LIVE: SpaceX Polaris Dawn Mission EVA (Spacewalk) - First-ever Spacewalk by Commercial Astronauts

[Music] [Music] good morning and Welcome to our live coverage of SpaceX polar is done space work the first ever space work by four commercial astronauts wearing SpaceX developed EVS suits it's just some hours away the PO is done crew will attempt the evf from Dragon today on September 12th at 2:23 a.m. eastern time we hope you all are doing fine and much excited about this special Eva before moving [Music] on let me just tell you now we will be discussing a little bit about the updates we receiv received from Polaris Dawn Mission and what what they did in this last two days after lift off and following that we will be starting the stream of the Polaris on Space Walk hello my name is dipto Mitra performing the commentary for today's special space work by polar is Dawn mission on behalf of astri team we express our heartfelt gratitude to everyone for being a part of today's live stream and we really appreciate you being here big thanks to our amazing YouTube Community for being here today as we provide detailed coverage of space launches complete with extensive stats and thought power insights now let me just start with the lift off at the very beginning of this Mission as you can see on your screen the polar is Dawn crew walked out for their launch about the Falcon 9 from space space uh excuse me launch complex 39a at nasas Kennedy Space Center in Florida back in September 10th at 523 a.m. following their workout they reach the pad using SpaceX Tesla cards on your screen you can see the crew getting transported they are right now on their respective Tesla cards on the way to Launchpad some happy faces and now J ISAC man coming with a big thumbs up following that the crew went for the increase procedure some happy smiles and waving there while they were about the Dragon although at the initial lift of time we couldn't lift the Falcon 9 and the mission so we had to delay due to the ongoing weather conditions out there later on we attempted the second launch opportunity during the 4our launch window that is at 5:23 a.m. eastern time 9:23 UTC and 2:23 a.m. Pacific Time on your screen you just saw how the launch was in a slow-mo another slow-mo video of the launch F 9 leaving the pad launch complex 39a with the four commercial astronauts about the dragon spacecraft and just about 10 minutes 12 minutes from that lifp off we saw the dragon separation from its second stage on the Falcon 9 heading to the initial orbit we are get we did got that time some nice views from the second stage following that we got an update that Dragon made its first pass through the South Atlantic anomaly also the shot for SAA a region where Earth's magnetic field is weaker allowing more high energy particles from space to penetrate closer to Earth the mission control operators and the crew worked hand to hand to Monitor and respond the vehicle system across all high APO phase of the flight particularly through the South Atlantic anomaly region and following that the crew settled in for their first sleep period in space during which Dragon will dragon performed its first apoi raising burn orbiting Earth higher than any human in over 50 years the crew rest for about 8 hours ahead of a busy day on flight day one excuse me flight day two and during the dragon's first orbit Dragon reached an oi of approximately 1,216 km making polar is on the highest dragon mission flown to date following a healthy system checkout the crew and the machion control monitored the spacecraft before the vehicle raised itself to an eliptical orbit of tracking 400 km Dragon you've soared to over 1,400 kilometers and you're farther from Earth than any other person since the last Apollo Mission over 50 years ago we all look forward to our friends at the emis program to take us to even greater Heights well said dragon nice views from there when the dragon was in orbit of 1,400 km we heard the mission control there communicating with the PO Dawn crew also we did saw that how the Draco thrusters from the dragon spacecraft made their work lifting the dragon to Reeve uh to reach the highest orbit to date any spacecraft went at an altitude of 1,400 km just for a quick reference you can see on the screen where Dragon reached its highest orbit and now just some hours left from the space work and where it will be happening the mission involved complex orbital Maneuvers starting targeting an epoi of 1,400 km that you can see on your screen the highest apoi there as of now ISS orbits around the world our world around 420 km during the inspiration Mission SpaceX pushed the boundry a little bit far farther and reach the orbit of 575 km M and this time they made it more and went to 1,400 kilm and following that addition to 700 km for the much anticipated Space Walk now after launching to an elliptical orbit with an apoi of 1,200 km and per of 190 kilm getting verified about the health of the Dragon spacecraft dragons Draco engines fired to raise the spacecraft epoi to an altitude of 1,4 km where Dragon remained for several orbits before lowering to a coasting elliptical orbit with an apoi of 700 km and per of 190 kilm for the remainder of the mission including today's space walk and preparing for the re-entry PO is Dawn will be the first non-government mission to perform a space walk but not only that it will do that about 700 km above Earth you can easily comprehend from the slide on your screen we are presenting that the International Space Station orbits Earth at about 420 km and today we will be having The Space Walk at 700 kilm so how much it makes a difference and why this mission is so anticipated also the dragon orbit Earth through regions of a highly charged belt of radiation also known as Van Allen belts there are two such belts around Earth an inner one and outer now those of who you are not familiar with Van Allen belt let me just make you understand in a easy way so here is a slide for you to make you understand how the Van Allen bels looks like this van alen belt is a zone of Mag excuse me energetic charge particles most of which originate from the solar winds and which are captured by and held around the planet by the planet's magnetosphere for us Earth has two such belts as I mentioned before and sometimes others may be temporarily created but those are temporary these two bels are permanent and this reside the these bels are named after James Van Allen who is often credited with their Discovery overall these two belts extend from an altitude of 640 to 500 uh excuse me 58,000 km above the surface the inner Van Allen belt extends typically from an altitude of 1,000 km to 12,000 km above the Earth whereas the outer belt begins at an altitude of 13,000 to 60,000 km above Earth's surface polariz da orbit so through a region called South Atlantic anomal which I mentioned before here the lower most of Earth's two Van Allen belts comes closest to Earth with high concentrations of electrons and energetic protons the Van Allen bels are harmful to humans if exposed for a prolonged period the crew's expected radiation dosage over just 5 days stay on the orbit is equivalent to 3 months stay about the ISS so you can make the difference as I mentioned before after completing six orbits of Earth at an altitude of 1,400 km Dragon performed a series of decent burn to reach an orbit of 700 kilm altitude for today's space walk also simultaneously they continue to lower the dragon's interior pressure bringing the cabin environment closer to the condition required for the Eva the crew also spent few hours demonstrating the suits pressurized Mobility verifying positions and accessibility in micro gravity along with preparing the dragon cabin for the upcoming extra vehicular activity in addition to the space work preparation the crew conducted a series of activities on orbit including time dedicated to science and research and all these 5 days of their stay they will be conducting some science and researches weaved throughout the mission the group focused on monitoring initial changes today on the flight day to their eyesight and ocular health we know about that sense so I will be making you to understand all this just make me to give you all the updates first then I we will talk about the mission once again also they studied how fluid shifts and exposure to the microgravity effect on the blood flow and assess how medications are processed by the body while on orbit following that the entire crew met with the representatives from pools of Honor good morning good afternoon good evening Dan Rachel and Kenley we're so excited to bring you along our Dragon capsule so we've been up here for uh just over 28 hours flying around and around the globe we're going about 8 km per second that's about 17,500 M hour going around every 106 minutes it's pretty wild to see Earth from this altitude we're up at 1,400 kilomet and why is that significant it's the highest anyone has ever been since 1972 when Apollo 17 went to the moon so it's a it's it's a beautiful uh opportunity for us to see Earth Mother Earth from this altitude and it's also pretty special because two of my crew members have uh set an altitude record uh for the furthest any female has ever traveled from the planet Earth uh let me take a moment and introduce my crew I'm kid potit I'm a mission pilot for polaron to my right you got Sarah Gillis her call sign is Cooper she is a mission specialist she's also an engineer with facex and then to my left you got our illustrious Commander two-time astronaut Jared Rook isaacman uh and then to his left is Anna Minn her call sign is Walker she is a mission specialist also a medical officer for this flight we are so honored uh to have this opportunity to talk to you guys uh you know it's um there's no greater than uh what you guys have done and what your spouses have have sacrificed uh for our freedom in our nation and we are forever grateful uh for that and and we just want to take a moment uh and and honor uh those sacrifices uh and try to carry on the Legacy uh of your spouses because it's it's so important what folds of honor is doing uh for these families um so it's just an honor for us to be here and and I'm G to pass it off to my crew to say a couple words hi there um so just want to really highlight the the opportunity of a stem education here and what FS of honor is doing it's a huge part of our mission and it's what goes into the incredible Feats that happen in order to go explore Among the Stars and go farther into the universe stem is such an important part um of everything we do to make progress and so just want to acknowledge and recognize what FS of honor is doing as an organization and how important it is and how grateful we are that you guys are able to continue providing education opportunities just want to say what um what a real honor it is to speak with all of you today um you know a little background on uh on the spaceship we're on right now it's uh it's actually named resilience and uh and that's what really comes to mind when I when I think about the the sacrifices that you've all made um and what you've endured and persevered and and really in the name of freedom um and again it's a it's a it's a real honor to to Really connect with you all today hey there I am so thrilled to get to talk to you guys today I also have a loved one in in the Air Force my husband and while we've made sacrifices they're nothing in comparison to what you all have had to endure so you know I just so admire what you do and your commitment to continuing their legacy and working with FS of honor and I just so appreciate you so thanks for everything you're doing and we're so thrilled to be with you today and with that we'd be honored to to hear from you guys Dan and Rachel and Kinsley you just heard the pois dawn crew having the conversation with the representatives from FS of Honor FS of honor is an organization providing educational scholarships to the spouses and children of America's fallen and disabled military service members and the First Responders it's an act of honoring those who have made the ultimate sacrifice in service to the United States following that event Ana Menan read her book kisses from space to a group of St Jude patients and to her family as well followed by a question and answer session also at that time all PC gold medalist Sean Johnson East joined the crew via a video conference to host the book reading here is a short clip of that hi Sean hi everyone hi James and Grace I am so excited to talk with all of you today and also get to read a book that's really special to me this book kisses from space is a story that I wrote for you James and Grace to remind you that I love you and that I'm always thinking of you even when we're apart but I'm also excited for another reason and that is the fact that this book raises money for St JW Children's Research Hospital I co-authored this story with Carrie vosik and it is beautifully illustrated by Andy Harkness and all of our proceeds are going to benefit the this hospital and the incredible work that they do so without further Ado let's read kisses from space gather around my sweet dragons your mama is back you just saw Ana Menan reading the book she authored skes from space also would like to mention if you want to have a copy of this book WR cases from space please go ahead and have a p because it will help to raise the fund for St Jude's Children's Hospital there and following this book reading Isaac man kid Sarah and Anna ended their flight day two with with the calls to family which was conducted over starting connections and they went for a good night sleep ahead of today's world's first commercial space walk so these were the updates we received for from Polaris Dawn up to the flight day two now we are in the flight day three the Eva day also we got a good view of the sunset through the external cam on the dragon you can see how beautiful it looks showing that thin atmosphere of the earth we hope that we could give you the best possible way to have the updates for the polariz dawn Mission now before moving on on if you feel like we are adding value to your viewing experience please consider giving this video a like it really helps YouTube's algorithm bring in more space lovers to discover this stream helping us to build a community with amazing space enthusiasts like you also consider about smashing the Subscribe button and turning on the Bell notification as we work hard to bring you detailed streams with stats and insights we would be super grateful for your support let's just talk about the crew a little bit jar Isaac man as the mission Commander is the founder and CEO of CEO of Shift 4 and also served as Mission commander of inspiration 4 Mission which was the world's first all civilian mission to space back in 2021 which helped raise over $250 million for S Jud Children's Research Hospital is an accomplished Aviator and adventurer from Pennsylvania Isaac man is rated to fly commercial and military aircraft and he holds several world records including to speed around the world flights next we have skid C put it serving as the mission pilot for the mission who is a retired US state Air Force Lieutenant Colonel and has 20 years in the service including commander of the 64th aggressor Squadron USF Thunderbird 4 demonstration pilot operational test and evaluation pilot also he served as a role of flight Examiner what it previously served as Mission director for inspiration for Mission Sarah Gillis Mission specialist for Polaris Dawn mission is a Colorado Native who is a lead space operation engineer at SpaceX where she is responsible for overseeing the company's Astronaut training program being a lead astronaut trainer she trained many of the crews that have gone to space including Isaac man who is the commander of Polaris Dawn mission for the inspiration for Mission she is a trained classical violinist Giles begin began as an intern for SpaceX in 2015 and worked on human in Loop testing for the dragon spacecraft Gillis has developed a curriculum a musicians guide to reaching for the stars that encourage enes students to reach for their dreams and discover the connection between music creativity and exploration let say we have Ana Menon Mission specialist and medical officer for the polariz mission who is a lead space operations engineer at SpaceX as well in that role she manages the development of crew operations and serves in the mission control as both a mission director and crew Communicator prior to that she was a biomedical engineer and supporting astronauts on console at Nasa as mentioned before she authored a children's book Kes from space which was inspired by her experience preparing for the polar Dawn Mission and her desire to share her space flight experience with her two young children as well as well as with the St Jude Children's Research Hospital the polar Dawn Mission will be the first of the three planed Polaris Dawn missions in the polariz dawn program the mission utilize Iz a flight proven Falcon 9 booster for its fourth flight launching from the historic launch complex 39a at kedy Space Center the polar Dawn mission is set to last for up to 5 days with an inclination orbital inclination of 51.6 De which is a common angle for Missions to the International Space Station due to its optimal ground coverage and accessibility before moving on would like to have a look at the chat and welcome our guests here firstly once again welcome Simon also would like to welcome one of our moderator here Popa thanks for tuning in hope you will be enjoying the stream and yes indeed those short from the dragon on orbit were really spectacular would like to welcome Jeffrey Frank thanks for tuning in really we are holding our breath to have this EV to witness and a big thanks to Patrick Vin for subscribing to us and tuning in we hope you all will be enjoying the stream and we could deliver our best to give you the overview and the good overall experience of the Polar Dawn Mission with the upcoming Eva extra vehicular activity now just let's discuss about the mission a little bit before the webcast Begins the mission involves several orbital Maneuvers starting with the targeting of an EP of 1,400 km which we already achieved with the dragon mission taking advantage of Falcon 9 and dragon's maximum performance endeavoring to the endeavoring to fly higher than any dragon mission to date and farther than humans have traveled since the end of Apollo program in 1972 the Falcon 9 lifted off from launch complex 39a at kinetic Space Center to an elliptical orbit with an apoi of 1,200 kilm and a pery of 190 kilm after verification of the healthy vehicle dragon's Draco engines fired up to raise the spacecraft apoi to an altitude of 1,400 km where Dragon remained for several orbits before lowering to a coasting elliptical orbit with an apoi of 700 km for the remainder of the mission including today's space walk before preparing for re-entry a little bit about polariz on mission objectives out of this checklist already we did the first one now we are awaiting for the second one for the first commercial space walk with this first commercial space walk Gil is and Isaac [Music] man to perform the Eva at a planned 700 kilom altitude we'll see several World Records three times higher than the ISS it will be the highest Eva ever in Earth orbit smashing an altitude record of 1,370 KM set by gini Gemini 11 astronauts Charles conard and Richard Gordon back in September 1966 attempting the first ever commercial space walk this will take place at an elliptical orbit of 700 km altitude above Earth in newly developed SpaceX EVS suits during The Space Walk The Crew will conduct a series of tests that will provide necessary data that will allow SpaceX teams to produce and scale for future long duration missions also the pillar Dawn 2 mission will be based on the data gathered from the the Polaris Dawn Mission and following that we will have the first human space flight using the Starship in the Polaris Dawn 3 mission the crew worked with the SpaceX Engineers throughout the suit development testing various iterations for mobility and performance and conducted operations inside the vacuum Chambers to validate pre-bath protocols and the Readiness of the EVS suit aged 30 years and 242 days on the planed date as of today of the Eva Gillis will also be become the youngest human to have a space walk eclipsing first ever space walker Soviet Cosmonaut Alexi leonov who was 30 years 292 days old when he floated outside the vcot 2 capsule back in March 1965 also jointly with Menan and GIS will fly to the highest altitude ever attended by a woman they already accomplished this Milestone as it is the highest altitude of the human space flight to date they made it double the 358 miles that is 576 kilm reached by astronauts KY torton Nancy curri and Megan MacArthur across three Hubble Space Telescope repair flights between 1993 and 2009 now following the Eva the Polaris Dawn Miss is set to test the laser Bas based satellite communication using optical inters satellite links between the dragon spacecraft and stalling satellites and during the whole stay of 5 days on orbit This Crew will the polar is Dawn crew will be conducting nearly nearly 4 experiments for critical scientific research designed to advance our knowledge of human space flight both on Earth and during future long duration mission space flight e let's just take a quick look how the [Music] training was done for the polar Dawn Mission by the crew ahead of the Polar Stone Mission during the last two years on your screen you can see the centrifuge and hypoxia familiarization [Music] training during this the Polaris Dawn crew completed their training to familiarize themselves with the symptoms that may experience while at the higher altitudes where there is a lack of oxygen as well as the G forces experienced during the launch and re-entry by having that centrifuge training in the centrifuge it's about 4 and a half to 5 GS similar to that the forces experienced during the various transitions on the way to space and back to Earth following that the crew spend time in the altitude chamber here on your screen right now you can see that slide getting familiar with their symptoms of hypoxia these are some of the images taken by John Crow would highly recommend everyone to follow him on X to have more such amazing pictures not only he's taking the Polaris on Mission pictures he do take some of the breathtaking pictures of every launch a big thanks to him else we would have been not get a good view of the Polar Dawn Mission at the back end now here you can see the Polaris Dawn crew participating in a decompression sickness study at NASA Johnson Space Center in Houston Texas December last year this facility originally served as a platform for similar atmospheric modulation test in the early 1970s ahead of NASA's mission to Skylab which was the United States first space station the risk of decompression sickness is lowered when the amount of nitrogen is reduced in a human body current extra regular activity decompression models such as those used on the ISS International Space Station achieve this during a long duration 100% oxygen pre Brea exercise in an air lock which requires the entire vehicle entire vehicle including the cube members to decompress down the vacuum with a limited prebid because Dragon does not have an air lock in anticipation of the mission's Eva attempt this study characterized the decompression sickness risk for polary stone and helped SpaceX to develop a new decompression model for EVS from dragon as the name just suggest this is just a dawn we will be seeing many upcoming EV EVS from the dragon itself in addition to character ing the decompression sickness risk the event also allowed for the crew and team to practice monitoring for and Reporting Eva related medical information and communication Loops ahead of the mission's actual space work the B Dawn crew members also climbed the cexi Strat volcano in Ecuador which presented them an opportunity for the crew to develop mental resilience for facing physical strains challenging weather conditions and evaluations at high as 19374 ft above sea level this allowed the crew to build upon their endurance and mental toughness which is a must need quality for the space environment also the crew went to the scuba driving training where we know that there is a limited way to communicate between each other this non-verbal communication and body support skills used in the scuba are comparable to communication skills used during extra regular activities which emphasizes the importance of clear and concise conveying of the information between crew members and team back on Earth the Zerg Flight Training of the polariz Dawn Mission which was essential for any astronaut to get accompanied to the weightlessness experienced in space these are 30 seconds of interval in which we experienced the z g during these flights so the crew utilized this opportunity to accomplish some of their science and research to see how that would feel like during the space mission the crew went through the skydiving training at the UN United States Air Force academ's basic Free Fall parachuting course in Colorado which is the only program in the whole world where the students make their first sky jump solo entirely uned from any instructors they soloed skydiving experience gave the crew continued valuable practice in making rapid High takes decision taking them alone similar to the Dynamics they encounter during the fighter jet training and other offsite team building events such as Kuba diving and mountaineering these are are some of the breathtaking pictures taken by John Cross during the flighter jet training which allowed the crew Resource Management teamwork and checklist procedures applied in high consequence environment this skill set translates into a space flight context where the crew must be prepared to react swiftly to a wide range of nominal and off nominal scenarios that could raise that could arise du during their mission replying to PO poika from the chat yes indeed the training was something these trainings will make anyone to have a complete wholesome training for a space flight making them to prepare mentally physically and psychology as well here on your screen you can see Anna Manon during her training in a medical skill training at Meo medical school at UT Health Houston their training focused on an internal and focused assessments collection of vital science physical exam skills basically life support and Airway management and other procedural medical skills en encompassing a wide array of potential concerns that may need to attend during the space flight so Anna and Sarah are the live saver you can say on the space flight right now now let me just check because I guess is time for the webcast to begin as they mentioned it will they will start the webcast prior to the prior to 1 hour from the Eva guys we hope that we are able to add something to your viewing experience if you feel so please like this stream so that it will reach a wider audience of space lovers so that we can have a good community of space lovers and space Enthusiast like you well we are getting an update that today at 4:52 a.m. eastern time Falcon 9 will be launching the bluebird 1-5 Mission launching the five first commercial satellite launch for as space mobiles launch will be happening from space launch complex 40 and currently the weather is 30% favorable for the liftoff hopefully we we able to stream because I don't want both the streams to go inside so as of now it seems like the webcast has not began so while we keep an eye on the webcast to commence let's just talk a little bit about the science and research aspect of the polariz Dawn Mission as we know the mission proof from the mission profile of the Polar is Dawn which affords us to have some great opportunities to expand our collect knowledge about the human body in space and Associated applicability here on Earth these are one of the most exciting and viral images during the polar Dawn Mission here you can see the crew members wearing a contact lens embedded with micro Electronics which will allow the crew to continuously monitor changes in the shape and pressure of the eye also this is a first for a human space flight Mission the collected data will contribute to an understanding of space flight Associated neuro ocular syndromes in short it is said as Sans a condition that can cause degraded vision and posess a risk of human performance during mission space missions to be particular next up you can see here Gillis who participated in an research where a device which will use the blood flow restrictions to help improve the efficacy of the exercise in space and also helps improve the effects of the fluid shifts that astronauts experience when they go to space some of the other science and research experiments you can visualize through this images this one is for the endoscopy or a camera that will be inserted through the nose into the AOA to gather imagery and look for the inner body challenges like inflammation the last slide which you saw where Anna was there that was about a research about which we all know that the balance and orientation issues that astronauts face when they return to a Earth's gravity environment so in that experiment a testing tool that might help with this issue where actually this slide on your screen right now you are seeing I'm talking about this which uses electric shorts between inner ears to stimulate that disorientation and balance issue and which will teach more about rapid adaptation skills to the Earth's gravity environment also the polar is on crew visited the St Jude Children's Research Hospital meeting doctors researchers and patients while throughout the last year working to raise funds and awareness for the hospital to ensure no child dies in the dawn of Life additionally by providing Starling to 100 schools in Chile and Brazil with starlink the Polaris team is striving to increase internet connectivity to commun communities around the world which can improve education and tele medicine efforts in communities in need of Greater connection to such resources although they did serve the staring satellites in Brazil as I mentioned but right now we know all know that staling is having some issues with the Brazilian government and also the Brazil government said that they won't be making any payments for the stalling Services being provided there and in reply to that Elon Musk mentioned that he will be making the service free as of now they at Brazil yes POA we don't have any images uh so far now that how people are sleeping inside the dragon we know how uh the astronauts are sleeping on the ISS we saw their sleeping beds those vertical sleeping beds but on Dragon we didn't saw it hopefully I think there was a slide or a video during the axm 2 mission where Peggy witson was inside the dragon sleeping bed but that was a closeup one we cannot understand anything from that that how its orientation is and where it is situated on the dragon spacecraft as of now the webcast has not begun yet we are awaiting for it and continuously checking for that so meanwhile let's discuss more about the polar is Dawn Mission here are some of the slides during the polariz dawn crew members checking the modified Dragon spacecraft for The Space Walk we know that PO da Space Walk will involve opening the dragons hatch forward hatch to be precise which has a new motor for the job for The Space Walk but the capsule won't feature an air lock this is different than space walking procedures on the International Space Station and NASA's retired space shuttle where the airlock has allowed the rest of the spacecraft to be isolated from the vacuum of space Dragon lacks of an air loock meaning all four Polaris Dawn astronauts will Dawn their space suits during The Space Walk and will be exposed to the vacuum of space Also the space Flyers cannot Purge nitrogen from their systems and avoid de decompression Sickness by using pre-breathing procedures as seen on the ISS inste the instead the spacecraft will here in the dragon spacecraft will gradually lower its overall internal pressure while the partial pressure of the oxygen Rises which will remove the nitrogen then all four astronauts will use pure oxygen in their suits while The Space Walk is happening po down Space Walk will be the first time that four astronauts will be concurrently exposed to the vacuum of space during the approximately 2hour long operation Mission Commander Jed Isaac man and Mission specialist Sara Gillis will separately exit the dragon spacecraft through its forward hatch Mission pilot kid and Mission specialist and medical officer on the Poli raed on Mission an a Menon will remain seated managing spacit emical and monitoring Telemetry on the diag interior display Scott and Anna both will be also monitoring the space Walkers that is the Isaac man and Sarah as they perform their Eva outside the dragon spacecraft we all know that the Eva today will be performed using the SpaceX new newly developed EVS suit which is designed keeping in mind that astronaut needs to move around easily both inside and outside the dragon spacecraft this space space suit is developed for the intra and Inter vehicular space activities that is the both and outside the dragon space craft and the team behind the elen musk back ventured used new materials production methods and specially designed joints that led the suit be Bend and flex to allow a high degree of Mobility the suits are having more flexible joints so that the astronauts can have more Mobility there are extra seals and pressure valves to ensure the space suit stays pressurized also SpaceX claims to have created a more convenient plug-in systems to attach attach the space shot to the vehicle this plug system is home to crucial elements such as communication kit cooling hardware and pressure control system one of the cool feature on the newly developed EVS suit is this EVS helmet which is a 3D printed and has special padding elements that house communication mics and pressure control Wes the new spacecraft comes with an upgraded visors that rotates and offers a wider field of view the helmet also incorporates a special display on display screen to be precise which is heads up display short in short it is h a camera to show critical information like pressure levels inside the space suit temperature levels and humidity moreover the company claims it reduces bright glare when astronauts are outside the spacecraft performing space work this new developed 3D printed Eva helmets their visors has a copper coating to protect against radiation as well using tin oxide similar to that employed on the wrap around cupola window that flew on inspiration 4 Mission the external fabric features flame resistant material with tlon fabric and NX playing a key role there deflon Fabrics were also a part of space suit used for Appollo programs NASA's version of fabric is called beta cloth which is essentially ultra fine glass filament used as yarn to make fabric and then coated with Teflon that is poly Tetra floro ethylene and with the melting point of having 650° Centigrade this material offers thermal shielding that protects against dangerous Luna dust for astronauts wearing the a7l space suits for the Apollo program Mission notably the suit Neil Armstrong wo for his historical Moon work had both tlon and nomix nomix is also used in SpaceX EVS suits which is a crucial element for firefighter suits for its flame resistance anomic is a preferred choice for making space shoots owing to its higher level of comfort and durability as well evolve from intra vehicular activity that is IVs suit the EVS suit provides greater Mobility a state of art helmet heads up display H and Camera new thermal management textiles and materials bordered from Falcon 99's interstage and dragon's trunk those of who are here right now on the live stream would like to just ask you that do you guys have any information about the webcast well well well we got the update the webcast will begin at 4:55 a.m. eastern time so it is it has been pushed a little bit nearly about 2 and a half hours right now we got this update so we have some more time before the webcast to begin once again like the lift off of the polarized on Mission we got to see the adjustment in the webcast there we had the 2 hours of adjustment and here we are having 2 and a half hour of [Music] adjustment yes Boba I just saw that as well that the Eva will begin at 4:55 a.m. eastern time actually that's a good decision I would like to say because already people who were much excited they were awake to witness this SP this Eva but now they can have a 2 hours of power nap before getting to witness this maybe that can happen POA but let's see what they can they have to say about this adjustment also I think with that we won't be able to cover the bluebird 1-5 Mission launch but let me just see if we can incorporate that launch here on this webcast only because current the system in which I'm working it is not possible to have two simultaneous webcast to host so with that we will ask apologies from all of you because we did plan and schedule the webcast for the SpaceX Bluebird 1-5 Mission but as the webcast of the Polar is done space work got shifted to 455 a.m. eastern time which will be coinciding with the webcast of the bluebird 1-5 mission for the as space mobiles from cap canaval so we would see that if we can manage here we would like to have you guys to have the webcast to witness on this webcast only so please don't switch to that scheduled live stream on our Channel's page for the bluebird 1-5 mission e e well as we are here on the flight day three that is the Eva day after the crew wakes up they have several hours of preparations including the final cargo configurations preparing biomedical monitoring devices for the space work they will get into the space suits and will perform a suit leak check and then perform the Eva following today the flight day four is the Starling demonstration day the crew will have some checkouts and then perform a series of demonstrations as a part of that test hopefully we will have a live stream for that as well flight day five is the final full day on Orbit on that day crew will be wrapping up all the research that they will be performing weaved in every single day of the mission and finally preparing for the reentry and with that it brings us to the flight day six having space routs on they will re-enter through to Earth's atmosphere and then splash down of the coast of Florida at one of the SpaceX seven sides and will be recovered by the SpaceX recovery vessel e previously after the dragon [Music] separation on the flight day two the incredible Milestone Dragon reached an apoi of more than 1,4 400 km marking the farest humans have ever traveled in space since the completion of the Apollo program over 50 years years ago on your screen you can see the drod thrusters out the dragon spacecraft these are the for forward bulk head R of firing during the burn reaching an apoi of 1, 14.7 KM today we got some good views Dragon you've soared to over 1400 km and you're farther from Earth than any other person since the last Apollo Mission over 50 years ago top that SpaceX uh we all look forward to our friends at the the Artemis program to take us to even greater Heights Dron you can see how beautiful the planet earth looks also this views from the dragon we got through the starlink communication system also one of the beautiful clip we got today as well of this orbital Sunset View From the cameras about the dragon spacecraft you can see that thing Earth's atmosphere with a white line just like a curve there due to the sunlight at behind now let us just check that what is the status for the SpaceX Bluebird 1-5 Mission well it will be launching from space launch complex 40 at Cape canaval space for station in Florida right now they are targeting a lift of time of 4:52 a.m. eastern time with the launch opening launch window opening at the same time and the weather is currently 30% favorable for the lift off that this will be the 13th Flight of the Falcon 9 booster supporting this mission and we will be seeing a first stage to land on the landing Zone one at Cape canaville space for station so let's just take a small break so that I can have a glass of water meanwhile you can have some music to hear here please be tuned in and I will be coming back and also you can have a break as well because we are having a good amount of time left from the webcast of the today's Eva to begin so I'm just joining you guys in in just couple of minute while you enjoy this

we are getting closer to the webcast of the bluebird 1-5 Mission so I will be a little updating this stream because it was intended for the PO Dawn Eva but although we made a mistake that to make it this stream to get live earlier than the when the scheduled time was for the PO is Dawn we just wanted to give you the more insights about this Eva and the polariz dawn Mission but unfortunately SpaceX adjusted the Eva time for the Polaris Dawn Space Walk so we got stuck here currently we have the blue bird 1-5 Mission live stream on our page but uh we won't be streaming from there we will be streaming here because currently as mentioned before we don't have the infrastructure to multi stream at the same time so please allow me a couple of seconds and the screen might get black so don't worry I'm still there just updating the stream it will take me 2 minutes only less than 2 minutes and I will be coming back [Music] [Music] e e e e guys I'm done with the setup of the stream for the blue bird 1-5 Mission currently we got that update that today we we are 30% having a 30% favorable chance for the web for the launch to happen SpaceX is targeting the launch of ASD space mobiles Bluebird 1-5 mission to low earth orbit although I don't know whether it is a low earth orbit or not it is not clearly mentioned from space launch complex 40 space SLC at Cape canaval space for station in Florida we have a 4-Hour launch window which opens at five 4:52 a.m. eastern time a backup launch opportunity is also available tomorrow that is on Friday September 133 again with a 4-Hour launch WI window opening at 4:43 a.m. eastern time now let's just discuss about the mission details today's here is a mistake I made while making this slide although there will be a nine Starling satellites being was being supported by this mission previously so please consider that today the booster with tail number 1078 will be supporting today's Mission the booster will be supporting this mission on its 13th flight which previously supported space screw Dragon 6 on 2nd March of 2023 SCS o3b M Power Mission and another non starlink mission that is the a classified launch of USS 114 Mission excuse me USS f124 mission I'm actually a little bit agitated because this I mixed up with the streams and previously as I said that uh ite supported nine staring Mission here on your screen you can see it is eight starlink mission written so it's a typo please consider that the last starlink mission mission supported by the booster was starting group 10-6 on August 2024 and that was the last supported Mission by this booster as well as of now this booster is having a 41 day [Music] turnaround now let's just quickly look into the payload details today's Bluebird 1-5 mission is the first commercial launch of the five satellites for Bluebird constellation and also for as space mobile the satellites are built at EST space mobile and its companies's 1 lakh 85,00 85 1 lakh 85,000 Square ft of assembly integration and testing space in Midland Washington this is a batch of five Bluebird cell phone compatible Broadband satellites each blue bir satellite has a communication array of 693 Square ft to establish this connectivity directly with the cell phones via 3gpp standard [Music] frequencies and also with the partnership with the leading cellular service providers all around the world each satellite consist of 10 m d 10 m diameter phased array antennas with an area of 64 square m which also consist of numerous identical sub antenna modules these satellites are built on the success of our of our inorbit blue Walker 3 satellite and will provide uset na wide non-continuous service with 5,600 cells in premium low band Spectrum which will make it 10-fold increase in the processing bandwidth so we can say that it will be a partial competition with the starting satellites now let's just quickly look into the stats for today's Bluebird 1-5 Mission this will be the SpaceX 383rd overall launch first launch for as spe mobile of five commercial satellites 31st Falcon 9 launch to date 371st excuse me Falcon 9 launch to date 13th flight for the Falcon 9 booster with tail number 1078 supporting the mission 88 Falcon 9 launch of this year this launch marks The 91st SpaceX overall launch of 2024 this will be the 316th Falcon booster reflight to date meaning a booster having a flight at least once before 205th SpaceX orbital launch from pad space launch complex 40 and 360 overall launch from this pad coming to some reusability statistics this will be the 32 Fon booster reflight to date 12th landing on Landing Zone one of this year and 44th Landing overall 13th Landing for the falcon9 booster supporting this Mission with t number 1078 and with that it will be the 75th overall land Landing which will Mark 328th Falcon 9 booster Landing to date and 347th overall SpaceX Landing prior to today's Mission these are the landing stats for different Landing zones for SpaceX Landing Zone one having one un unsuccessful and 43 successful land land ings to date with today's Mission it will be having 44 successful Landings whereas Landing Zone 2 is having zero unsuccessful Landings and 11 successful Landings whereas the Vandenburg Landing Zone 4 is having zero unsuccessful and 20 successful Landings now let's just take a quick look at the SpaceX stats for this year including today's Mission launch SpaceX will be having a total of 91 launches this year out of which 61 are starting missions 28 are non- Starling missions including one from today for commercial organizations as well as Government organizations which are having a noning missions and two Starship boost uh Starship launches these non stying missions also consist of the 10th Falcon heavy launch for the go you Mission previously SpaceX will have a 85 times of reused booster with today's Mission launch the geographical distributions with today's launch it stands with 60 launches from East Coast 17 from kedy Space Center and 43 from space launch complex 40 including this mission on the west coast SpaceX is having 29 launches and in the Gulf Coast of in the Gulf Coast they have two Starship launches back in Texas with today's Mission they will be nailing 88 times of Landings most of them are on drone ships today's one is not a drone ship Landing this one is a rtls operation that is return to launch site operation so it will be landing on Landing Zone one but uh among the Drone ship Landings they are having 69 launches uh Landings overall out of that 24 were of course I still The View 20 on just read the instructions and 25 on a shortfall of Gravitas and as of ground Landings they will be pulling it off 19 times with today's Mission Landing Zone will be witnessing 12 12th Landing whereas Landing Zone 2 is having two Landings and Landing Zone 4 is having five Landings prior to today's Mission the overall Landing success rate is 98.67% for the land Landings and for the Drone ship Landings it is 96.11% with the overall Landing success rate with 346 successful Landing is 96 65% for this year the overall Landing success rate is 98.85% now with today's Mission launch here is a buy chart showing the orbital launches this year USA having 104 launches including electron launches and taking a share of 63% of the pi China having 40 launches with 24.2% of the P Russia Russia with the recent so ms26 launch yesterday is having 10 launches having a 6.1% of the P Japan four four having four launches with 2.4% of the pi India is having three launches having 1.8% of the Pi while Iran and Europe both are having two launches with 1.2% of the pi respectively here is a pie chart showing the orbital launches made this year by rocket variation with today's launch Falcon 9 will be having 88 launches this year making 52.7% of the pie rocket lab with its electron having 10 launches taking a share of 6% of the pie so use two rockets from Russia having nine launches which takes a share of 5.4% of the pi China's Long March 2D also known as to CZ 2D having five launes taking 3% of the P next up China's long march to C no also known as CZ 2C having four four launches and taking 2.4% of the pie and that another Big Slice labeled others that is a mix of different Rockets launches having like Vega launch Aran 6 then Vulcan centor P Ros sslv launches China's gravity one long march 6A Long March [Music] 7A at last five launches so I'm not taking all the names and they collectively have 51 launches in total taking 30.5% of the pie with that we are 2 minutes away from the webcast to begin hope SpaceX will be sticking with their lift of time of 4:52 a.m. eastern time that is is the opening of the launch window for today's Mission launch as of now we couldn't make it to understand that what will be the trajectory for today's launch so we couldn't make you to see how what is the trajectory for today's launch because we need a little bit research to do for that and we didn't got time in between so pleas pardon us for that and upon completion of this stream we will be immediately switching to the EVS stream e the webcast began but uh we are not getting any well okay fine just a second I'm switching to the webcast for the bluebird 1-5 mission e we are just about to have the webcast to begin for the as space mobiles Bluebird 1 1-5 mission e e e good morning it's Thursday September 12th and you are looking at a live view of our Falcon 9 rocket awaiting its 4:52 a.m. eastern time launch from space launch complex 40 at cap paval space for station in Florida Welcome to our live launch coverage of as space Mobile's Bluebird 1-5 Mission today's launch marks spacex's 88th mission of 2024 and in the thir 383rd overall mission to date my name is somia shosta and I'm a heat shield engineer here at SpaceX joining you from Hawthorne California we're just about 12 minutes away from launch both the vehicle in Ranger Green and we are on track for an ontime launch at 4:52 a.m. eastern time although we do have a 60% possibility of violation on weather so we are keeping an eye on that today's mission is as space Mobile's first of five launches of their Bluebird commercial satellites which are designed to work like cell towers in space directly with everyday mobile phones today's Mission follows as space Mobile's blue Walker satellite 3 which launched on a falcon 9 Mission back in 2022 blue Walker demonstrated satellite direct to cell phone calls data downloads streaming video and video calls as plans to build a constellation of many satellites including a Next Generation Bluebird that's three times larger than the bluebird satellites launching today which themselves are about half the size of a volleyball court before we meet today's Falcon 9 let's take a minute to learn more about as space mobile and its blir satellites e large thin arrays made of microns each Micron has solar cells on one side that power cellular antennas on the other together they form a phased array with an area of nearly 700 sare ft that's just under half the size of a volleyball court yet each folds up to the size of a large refrigerator this allows our Engineers to tuck all of the satellites inside the top of a rocket or fing it takes under 10 minutes for the rocket to accelerate to 17,000 mph and reach a Zone called Low Earth orbit or Leo hundreds of miles above the planet each packed up satellite separates from the rocket our team will check all Satellite Systems before releasing each Bluebird from its container next the microns will start automatically unfolding as an array once the array is deployed two steerable antennas will pop out from from a central Hub called the control sat a monthlong process then begins to bring the satellites into service with industry-leading Partners like AT&T Verizon and vone among others this includes spacing out the five Bluebird satellites in Leo to provide optimal coverage so how will these marvelous machines squash dead zones the same way phones normally work with cell towers and providers let's break it down in a regular Cellular Connection a smartphone attaches to antennas at the top of a tower when the signals are strong enough at the bottom of the tower a base station computer interprets those signals like a switchboard operator connecting the phone to networks like AT&T's and Verizon and the internet each Bluebird array is like squeezing hundreds of cell tower tops together this allows each satellite to beam hundreds of cells of coverage over hundreds of thousands of square miles as it flies overhead in the US bluebirds will connect directly to unmodified phones using premium low band cellular Spectrum these signals can pass through foilage cars and even buildings meanwhile our Gateway antennas on the ground connect the satellite to our partners networks it's like combining hundreds of Base stations our solution makes smartphones function as if they are connected to ordinary cell towers to provide continuous coverage we plan to launch many satellites including a Next Generation Bluebird that's three times larger as we build out our constellation we aim to bring seamless 4G and 5G cover coverage to the US flying additional bluebirds would help build substantial Global coverage kicking off a bold New Era for mobile and human [Music] connectivity the bluebird satellites which are built by as space Mobile in Midland Texas seek to help connect the unconnected around 2.6 billion people have no internet access and more than 5.5 5 billion cellular subscribers still experience coverage gaps as space Mobile's goal is to provide 4G and 5G cellular Broadband coverage to even the most remote of areas including highspeed downloads streaming and video calls plan service could also assist first respond First Responders and help with Disaster Recovery today's mission is a critical step for as space mobile as they continue to expand their Network and bring communication services to even more people around the world now let's meet Falcon 9 Falcon 9 is a two-stage rocket developed and manufactured by SpaceX known for its safe reliable and costeffective access to space it's all it's also the first and currently the only orbital class rocket capable of reflight starting at the top of the vehicle is the payload fairing a protective shell that encases the payload being sent to space complete today's fairings will be flying for their 18th and eighth times today and will be recovered by our recovery vessel go Cosmos after launch that fairing will separate and jettison away from the vehicle exposing the payload once Falcon 9 reaches space Here's a photo of these satellites being encapsulated in that fairing just a few days ago continuing down the vehicle we have the second stage the second stage is powered by a single Merlin vacuum engine or mvac which is optimized to perform in the vacum vum of space and below that is the first stage which contains eight engines arranged around one Center engine held in place by a structure called the octaweb each of these nine Merlin 1D engines delivers about 190,000 lbs of thrust at sea level which gives Falcon 9 a combined 1.7 million pounds of thrust at liftoff the Falcon 9 first stage is also equipped with four Landing legs that deployed just before landing to allow for vertical touchdown on a drone ship or a landing pad let's take a look at today's flight profile today Falcon 99's primary objective is to launch the five Bluebird satellites into low earth orbit and in order to do that Falcon 9 for retra Falcon 9 will follow a trajectory that takes it Southeast over the Atlantic Ocean climbing vertically before curving down range in a maneuver we call the gravity turn where the rocket starts B bending its path to race along the Earth's surface we just heard the call out that a strong back will be starting to retract right now you can see on your screen the clamp arms underneath the payload fairing opening up and after that we will be reclining the strong back about a degre and a half away from the Falcon 9 it will remain in that position until lift off it's when it will be rapidly pulled back for the falcon9 vertical asent today's booster will be landing on a landing Zone one as this one is a rtls operation also yes Fair made ref uh one of our moderator here joined us today yes I'm good but uh not so good because was awake for the Eva to get prepared meanwhile I started the Eva to provide all the details but they made it now we got the call out that stage one locks load is complete now we are waiting for the stage two locks load to be getting completed just around 2 minutes mark from lift off and upon completion of the stage two locks load that time Falcon 9 will be fued with 1 million pounds of propellants ready for its lift off with the bluebird 1-5 Mission consisting of five Bluebird satellites now second stage locks load is complete as well right now we are venting the pressure that was there in the tubing of the strong back that's why we can see those white cloud right now we are performing The Grand uh ground gas close out and at T minus 1 minute we will be getting a call out for the Falcon 9 being in startup Falcon 9 is in startup just heard that Falcon 9 is now in startup which means the internal flight computers have taken over for the launch countdown now LD will get give the go go for launch and the launch director or LD has given the final go for launch so at T-minus 35 seconds all systems are go for the launch of Falcon 9 and we have the LI V ping down F9 has Tower we got the call out ision is nomal good call there stage one proportion is nominal as well C at t plus 33 seconds and counting Falcon 9 has successfully lifted off from slick 40 after clearing the tower we tilt or gimble the engines to initiate a roll maneuver which you May notice in the stage one camera view this enables the vehicles antennas to stay in the best position for communicating with the ground we got the call out for the power and Telemetry being nominal now at in 10 seconds we will be having the max Q right now s 9 s super seated Mark 1 it is faster than the speed of sound now we had the max Q This is a moment of peak mechanical stress on the rocket now upon this we will be having M back engine Shield prior to its ignition we started the M back Chi right now and after that we will have three successful three rapid succession events coming up first and second stage will separate after that excuse me first we will have the M code then we will have the stage separation and following that we will have the stage one flip following that we will have the second stage ignition following his its engine chills right now we had Miko State separation is confirmed and here we go you we have the M back ignition also known as scs1 right now we will have the stage one flip and following that we will have that for stage boost B burn to start at t + 11 seconds we are just yes 11 seconds away from that fairing separation will occur those fairing halves will be jettison exposing the payload to the vacuum of space fairing separation confirmed there we go we go have the fairing separation being confirmed we got a glimpse of the payload there and we had boost back shut down right now both the vehicles are in nominal trajectory at t + 6 minutes and 4 seconds we will have stage 1 entry burn to begin that entry burn of the first stage should be lasting for 11 seconds up to t + 17 seconds with the beginning of the entry burn at t + 6 minutes and 4 seconds and following that we will have the first stage Landing burn at t + 7 minutes and 8 seconds and nearly about 20 seconds from that out the landing burn we will have our first St Landing that entry burn coming up in about 30 seconds where Falcon 9 will decelerate by firing its Merlin engines guys as of now the webcast of the PO is done has started just after the landing we will be switching to that you great call out there and you can see the entry burn just completed but you can see that uh that the stage one is still continuing to move really really fast even though it is slowing down during entry burn the vehicle is flying through Merlin's exhaust gases or or its plume which deposits a layer of so on the vehicle surface and that soot comes from the carbon based fuel that Falcon 9 uses and each flight the soot builds up a little bit more on the outside of the vehicle we have Landing burn coming up in about 30 seconds from now right now I guess we can see those rights from The Landing side there and we got to see and there we go landing legs are deployed and we have a touchdown so with that we will be wrapping up this bluebird 1-5 Mission stream right now we will be switching to the Ava webcast just give me a couple of seconds be tuned in I'm just reconfiguring the stream for the webcast of the PO is Dawn to begin e e e e e is a lead space operations engineer here at SpaceX and she's responsible for overseeing our Astronaut training program she helped prepare NASA astronauts for the demo 2 and crew one missions and most recently directly trained the inspiration for astronauts Sarah is an experienced mission control operator who has supported real-time operations for dragon's cargo resupply missions to and from the International Space Station as navigation officer and as a crew Communicator for dragon's human space flight missions in 2015 while studying at the University of Colorado Boulder Sarah started an internship at SpaceX before moving into the Astronaut training program full-time and capping off the Polaris Dawn crew mission specialist and medical officer Anna Walker Menan who serves as a lead space operations engineer here at SpaceX where she manages the development of crew operations and works in mission control as both a mission director and crew Communicator during her time at SpaceX Anna has led the implementation of dragon's crew capabilities and developed critical operational responses to vehicle emergencies prior to SpaceX Anna worked for seven years at Nasa as a biomedical flight controller for the International Space Station she received her bachelor's degree in mathematics and Spanish from Texas Christian University and her master's degree in biomedical engineering from Duke University everyone on this Mission certainly has the background the qualifications you would want in your crew mates when you're going into space that's clear but let's take a moment now to meet our Polaris Dawn crew in their own words hi I'm Jared isaacman I'm Scott kid potit I'm Sarah Gillis and I'm Anna Menan and we're the players Don crew I Love This Crew I mean all of them are just so hardworking so smart kid potit over here is our mission pilot talk about a career in the Air Force doing every job as a pilot that than anyone could aspire to to achieve and having somebody who has you know been there before and can bring that perspective to our training but also when we're on the mission is just so important we are what we are as a crew because of you you hold us together and you are always there glue glue you are always there predicting what every person means um and he's needy what our commander Jared I think he is incredibly sharp that's right something I have just witnessed over and over is that he's always like five steps ahead of everybody else he's a Visionary he wanted to make it bigger than just himself going to space it was about uh how we could contribute and support organizations here on Earth uh as well as continue to push the envelope for space exploration so Sarah Gillis the technical confidence we don't get out of any engineering update or brief or go through a procedure deep brief without getting into the weeds and making sure every tea is crossed every guy is is is dotted she holds my feet to the fire uh when when we need to uh understand the systems and the operations it's it's her intellect every time she speaks every word is so thoughtfully prepared that served her in her role as core it serves her in her role as a trainer Anna you have this incredible joy that you bring to Everyday Life it is infectious it makes us all smile feels like she always has this big picture doesn't necessarily always speak up on it but when she does it's like time for everybody to to stop and and listen and then as a biomed engineer and a background like that inspires like a ton of confidence that we go up there if uh if people aren't feeling right that she's going to be there to take care of I cherish all the moments that we've had in these experiences and uh we're just so excited to to go to space now that you know a little more about the Polaris Dawn crew let's recap the mission so far and what's coming up next since liftoff and getting to their initial Orbit on day one the crew has been quite busy the crew had a few meals got some rest and spent a few hours demonstrating the Eva suit's pressurized Mobility to verify positions and accessibility in microgravity the crew also prepared the cabin for the Eva and of course had an opportunity to talk to their families and check in as I mentioned earlier on day two dragon proceeded to a high apy of more than 1,400 km higher than any dragon mission to date this was also the farthest from Earth for a crude spacecraft since the last Apollo lunar mission in 1972 in preparation for the spacewalk dragon has been executing a series of a apogee loing apogee lowering phasing Burns by now dragon has lowered itself from the highest apog of the mission of more than 1400 km to about 190 by 700 km above the Earth also on day two the crew was joined on air by some very special guests uh as you can uh see here we uh we are not here but we had patients and families at St Jude Children's Research Hospital um and they they're joined Live While polaron crew member Anna mened read from her new book kisses from space along with the patients and family amilies at St Jude and his children James and Grace also joined the reading and afterward the crew hosted a Q&A and speaking of St Jude for this Mission the pois dawn crew Enlisted the help of Childhood cancer survivor live to create the missions Zerg indicator while not a St Jude patient herself Liv met the inspiration for crew and inspired by the mission of St Jude she agreed to share her talents to support polara Dawn e e I want asteroid to be for every child and help them see oh rest went to space and I can to I can achieve my dreams we are also flying Liv's original drawing that you see there that was used to design the Zerg indicator which we plan to return to her after it has flown in space and while her design was inspired by the working dogs of St Jude Children's Research Hospital Alo donations from the sale of asteroid will will be General donations to St Jude the inspiration 4 Mission helped raise more than $240 million for St Jude Children's Research Hospital and polaron will continue to raise funds and awareness for St Jude while partnering with the organization to provide Health Care in underserved communities around the world now if you want your very own asteroid they are available at shop.ace x.com and polaris.com I did just look Unfortunately they are sold out right now but there are more on the way so be sure to check back at those sites to catch one of your own myself included I missed the first drop so uh I got I snagged one I got in there I got a kid who nice these one all right now the first phase of The Space Walk the preparation actually started just about 2 hours after the crew reached orbit and this is when the pre-breathe process started that's when the oxygen started to increase incrementally as the actual the Cav pressure inside Dragon was started to get incrementally lower the pre-breathe process is designed to decrease the amount of nitrogen in the body which then reduces the risk of decompression sickness which can happen as atmospheric pressure lowers protocols like this are used for any space walk done today and might feel familiar to anyone here on Earth that has gone scuba diving and done a decompression stop after ascending from a pressure of in deep water back up to the surface and to do all this dragon's just been slowly decreasing that cabin pressure that allows the crew to acclimate each time the pressure gets lower as they get ready for the lower pressure they'll be in in the suit during the spacewalk itself they've got the ability to pause the process if they experience any discomfort but the ear ear equilibrium just kind of naturally adjusts as the pressure decreases it's kind of like when your ears pop when you change altitude on an airplane um all four astronauts are going to be suited for this the spacewalk today cuz Dragon does not have an airlock that's also kind of why the entire cabin is going to be depressurized it's why we have this kind of unique pre-breathe process with the stuff today too all that brings us to now so far the crew has prepared the cabin for vacuum which includes securing all loose items that they don't want floating around they also completed medical checks suit inspections and final checkouts of the oxygen venting and nitrogen repressurization systems after that it was time to put on their Eva suits and now Jared and Sarah will be exiting the spacecraft today while kid and Anna will be supporting from the inside crew in the outer two seats kid and Anna are going to be fully strapped in and then the two in the middle seats Jared and Sarah are just going to be lightly secured ahead of The Space Walk since they're going to be moving around and eventually heading outside as we listen into comms during the Eva you may hear the crew referred to as ev1 which is Jared and ev2 which is Sarah support one is kid and support two is Anna again they will not exit the dragon during the Eva but make no mistake they are very much performing in Eva just the same and their data is being collected as well once everybody's in position the seats are going to get rotated upright generally they stay in the recline position for the majority of the mission but we're going to rotate those upright during the Eva just to give more room to move about after that se rotation the crew verifies that their heads up display or the HUD on their helmet visors are turned on operating as expected this is how the crew will actually be able to keep tabs in the health of their suits and they'll get some other stats of their suit operation during The Space Walk and that will take us to the first official go noo checkpoint to determine if the Eva can proceed after an operations bre from the SpaceX team the crew will announce their go noo status and then it'll be time for The Space Walk to begin it's expected to last about 2 hours from the time that O2 begins flowing to the crew suits until we complete the repress of the cabin and just prior to we get to cabin venting pure Oxygen's going to start flowing to the cruise suits that's when the Eva clock will start so keep an eye on that and this all gets followed by a suit leak check we'll do the leak checks once those look good Mission Control will start to vent the cabin just removing the air in order to lower its pressure down till we can get to hatch opening next dragon will use its Draco thrusters to reposition itself so that the trunk is facing the Sun this will help keep temperatures Communications and spacecraft power stable during The Space Walk at this point the crew should be ready to open dragon's hatch and exit the spacecraft after the hatch gets opened ev1 that's Jared's call sign during The Space Walk he's going to be the first to exit the spacecraft he's going to go outside and he's going to do a series of Mobility tests these are kind of the core component of the spacewalk today he's going to basically take the Eva suit through the paces it's going to take about 15 minutes before he climbs back into drag Dragon after that ev2 or Sarah will step out into space to perform the same tests of her Eva suit before she then climbs back into dragon in addition to the suit Mobility tests Jared and Sarah will also evaluate dragon's new Skywalker Hardware we'll talk more about that in just a bit and then after she's completed her test Sarah will stand by near the hatch for the actual closing and at this point after the hatch is closed the Eva is not over the hatch door gets closed and then the cabin has to be repressurized we got to get all that atmosphere back inside after we start introducing that atmosphere we'll do cabin leak checks once those leak checks are complete the crew will return to their seats and the Eva will be complete when the cabin pressure has returned to nominal so for now the crew is suited up and awaiting final checkouts and Eva venting which will bring in dragon to vacuum uh with everything on track we're about 45 minutes or so from the start of the spacewalk and before we get there though we're going to expand the desk a little bit we're happy to be joined by former NASA astronaut Mike Hopkins we were fortunate to have him tune in with us uh during the launch and now we've got him to talk to us a little bit about space walking today good to see you Mike yeah it's great to be back it's great to be back here in Hawthorne with you tonight on this uh very memorable night for sure yeah absolutely uh now Evas may be new to SpaceX but uh you have particip ipated in five yourself uh while you were on the International Space Station and spent a total of 333 days in space that's that's pretty cool yeah I mean I was very fortunate uh on my two Mission Jo the first one was back in 2013 and I uh I went up on a Russian soy use and on that one we had two space walks and the interesting thing about those space walks is they weren't planned uh they were what we yeah they were a big surprise for us uh contingency spacewalk and of course surprise happen at Christmas because that's when we actually went out the door our second walk was on Christmas Eve and uh that was pretty exciting to to be doing a spacewalk as everybody was getting ready to celebrate Christmas down just helping deliver presents that's right that's right and then your first play was on the so but your second one you were the commander of crew one I mean that was obviously really huge for everybody here that was big for me I was there with you at Nasa still that was a huge moment that was the first like long duration mission to the space station on dragon and I mean you you really got to know Dragon probably more than anybody cuz you you actually got to call it home while you were docked up there that's right I mean I tell you it was quite an honor to to get to be a part of that crew to get to command that crew um and and it was an great amazing group of people not only uh uh Victor Shannon and suichi but also everybody that that helped get us there at SpaceX and at Nasa but yes you're right Dan um while we were on board we we didn't have enough Cruise stations and actually you can see a picture of uh where I slept while I was on board for that second mission and uh it was actually quite comfortable uh and one of the best parts about being able to sleep on Dragon is that I had a view I had the window and our other crew quarters did not so I've got some amazing pictures from my time staying in Dragon that's amazing um it's great to have you here I had the pleasure of watching you launch uh in person I was hosting the crew one launch from the NASA press site and it was just so cool to see everything light up and just watch you ascend to the space and where the station where you made it your home it was also so great to see you here around campus during your training period um to seeing you here on the Mez having lunch and uh that was really cool and during that time you got to get the spa get to know the SpaceX team pretty well in fact Anna and Sarah uh were two of your Trainers for crew one weren't they they were yes and uh you know I got to for the launch we saw some of their videos of training and I I thought it was kind of fun to see see them as trainees and somebody else get to uh getting to test them all the time so yeah it was pretty neat to to get to see that switching it up a little bit cuz we're we're starting to get some views back from Dragon we've been treated to some pretty spectacular stuff as we were you know all the way out to 1400 kilometers uh we like to talk about something called the overview effect so kind of that first that and we're getting some coms from our crew too yeah nice SpaceX Dragon radio catch loud and clear kid help me catch loud and clear doin continues andless just going to be mik make that Dawning all right some some quick com checks we heard kid that got po he's going to be one of the support crew in there today so our our first calms down as we get ready for The Space Walk uh but we're looking out the view we're looking down at Earth that overview effect what's it like the first time you get to space you get to look back and I mean you can see Horizon to Horizon the whole the whole earth below you you know it's kind of funny Dan because uh the overview effect is definitely real but when I first got to space um on that on that soy use gosh how many years ago almost 9 years ago um I had this really weird feeling of falling and and so when I looked out that window the first time I wasn't really thinking the big thoughts of an overview effect I was kind of thinking like what is going on with my body right now this feels really that's pretty but oh no yeah um but again fortunately when you have time to be in space you you do have an opportunity to experience that and it is definitely true um you know you hear people talking about that that small sliver of atmosphere and you you see that and that's what's keeping us alive you you see a World Without Borders uh which is incredible but uh you know one of the experiences of the overview effect that I had was that you know that it gives you that sense of answers but it also for me gave me a lot of questions and made me realize that there's a lot of this world I don't really know much about the other other parts other countries other societies cultures languages and and so it sometimes it as many questions as it did answers hopefully a bunch of bunch more trips then right that's right that's right uh now for those of us who have never been to space uh it can be hard to imagine uh looking down from there uh here at Planet Earth um space photographer and author Frank White originally coined the term the overview effect in a book of the same name here's a little more on the phenomenon that few of us have yet to experience the overview effect is that sensation or that feeling that you get when you see our whole world from the perspective of being outside of it it ranges the whole Spectrum from like how delicate the Earth may appear because you know it's only this Thin Blue Line that separates this habitable atmosphere of our home planet to you know the vacuum of space it's hard to comprehend what the impact is going to to be when I first see Earth from space it just reminds us of how fragile our planet is one of my roles on this crew is to shoot as much footage as we possibly can so we can bring it back and share it with the world the big picture awareness that you gain from that sort of perspective when you were you know journeying amongst the stars and and see our our entire planet as we know it there outside of your window and kind of the the philosophical and the the many different emotions that it provokes inside of you when you see it that way we have barely begun our journey to explore the worlds around us and that hit me right when I saw the the moon rise around Earth and saying like come on it's been 50 years we got to get back there and we got to get to Mars and we got to figure out how to get out of our own solar system and try and figure out what this is all about there's so much in incredible footage that crew members have taken from space and that you see from satellites I think it's one of the things I'm looking forward to most on the mission is getting to see the Earth from that perspective I can't wait to share what that experience is but I guess I'll have to let you know once I get back and I mean I I think I speak for a lot of space next support is next and then ev1 and2 behind copy on that crew status getting a quick quick crew status from kid H yeah I I think I speak for a lot of space sees we we really want to get up there and see that view to feel that effect to experience that um and being able to see it just from dragon and you know pretty soon getting able to see a couple of people go out of dragon for the first time in a space walk I mean space walks are kind of like living on the edge with space flight it's it's always really cool it's it's really important for just about any program like what are what are some of the things when you were outside the space station what were some of the things that you were working on Mike yeah so when when I went out I mentioned that first space Walkers contingency we had a failure and so sometimes when we're going outside it's it's not planned and you have a component that that is no longer working and in this case it was a part of the cooling system external cooling system on station and so we needed to go out and replace this refrigerator size pump module and and so that took us a couple walks to do that other times we're we're going out and we're putting a new piece of equipment on board um sometimes uh normal maintenance sometimes we're upgrading equipment like uh new solar arays new batteries and and things of that nature and and sometimes you're doing like what uh what the Polaris Dawn crew is going to do today and you're just checking out the suits and checking out the equipment that that you're going to use in future spacewalks as well now uh with all of the experience that you have up there I'm guessing there might be uh an Eva experience or achievement that you are particularly proud of well I'm I'm uh yeah I'm proud of every of every one of them right when you uh when you get out the door and and then you come back in safely I think every that's what everybody that's what everybody wants to do um SpaceX for awareness we're going to be commanding a couple fans right here you'll hear them run but then we'll also be turning them off no correction required cby actually uh if I can I'm just going to jump in on that that's actually a very important call that was made you heard him say we're going to turn on some fans because when you're in space you acclimate to the sounds around you of the vehicle and when it changes all of a sudden you're kind of looking around of what was that and so you heard them give them a warning that we're going to turn on some fans yeah and so that they kind of knew what was going so that's actually a great call from the ground there um but uh but anyway going back to those those space walks where I was uh you know outside and and what are you're proud of you're you know it's it takes so much to put these vehicles up into space and and so when you go out on the spacewalks and you know that um you're a part of keeping that going a big part of it is you don't want to mess up right because uh people are depending on you and couple people watching over your shoulder that's right and so when you get back in and they call up and they say hey that repair that you just made everything's working looks good station's back up 100% it's like okay that's that feels great Dragon Space X our fan commanding is now complete all right hopefully no surprise sounds in there for him so I mean spacewalks are something that you you train the heck out of they they're planing down to like the minute what are you know why like what are some of the challenges you can you can run into when you're outside doing a Space Walk yeah so I mean one of the first challenges that you're always worried about is the how your suit's functioning right because that's what's keeping you alive when you're outside like that so uh there are always you know you're monitoring your suits yourselves people on the ground are monitoring your suits and how that's performing and so those are certainly things that you need to be conscious of and and aware of um and and then when you're out there as well uh there are so many steps that it takes to get through a space walk I mean hundreds and hundreds and hundreds of steps and so it's too much for you to remember and so that's where there's a it's a teamwork between you and the and the ground and so they're making all those calls hey here's your next step here's what the settings are for these tools and and they're just walking you through the whole process and and so I think that's one of the neat things about space walks that uh maybe people don't realize is you know you focus on the on the people actually getting to go out and and do the walk uh but but the team on the ground is such a huge part of that as well uh so on your third fourth subsequent Evas um you know they ex these space walks um they they you you train a lot for them beforehand before you even get up in space uh by the time you're on your fifth one it must have been more like a cakewalk it no it never felt like a cew walk at at all um you know it because it is you know it is a a risky Endeavor right so every time you go out on the spacewalk you're definitely uh very very focused and and you never want to let your guard down with it I will say you certainly are are more comfortable with what's going on more familiar maybe is a better way to to say that but I think um you can kind of trace it back to experiences down here on Earth for me A lot of times it's my uh Sports background so I'll equate a little bit of of going out and playing a football game right before every game you're still nervous right you still got a lot of that energy it was the same thing on my fifth Space Walk Like it was on that first one you know you still have all that kind of nervous energy you're getting ready to go out well so right now we're still kind of waiting to get into some of the final preparations for this space walk uh we should be coming up on SE rotation I don't know if we missed it or not but again they're going to be rotating those seats uh to move them upright that's just going to give the crew a little bit extra room to move around as we get into this uh but for now why don't we take a couple of moments and meet Dragon uh Polaris Dawn is space X's 14th human space flight Mission since 2020 when Dragon became the first private spacecraft to take humans to the International Space Station it's also the first private spacecraft to take an all civilian crew to orbit during the inspiration 4 Mission in 2021 and just prior of Polaris Dawn Dragon completed 46 launches 13 of those are human space flight missions and it's since flown 50 astronauts representing 14 different countries throughout all of those missions drag has helped support more than 1,000 experiments in space pretty incredible stats there um and even from low earth orbit dragon is helping lay the groundwork for deep space exploration through missions like inspiration 4 and Polaris Dawn we are rapidly expanding our knowledge of how humans will adapt live and work in space designed to be the safest spacecraft ever flown the fully autonomous Dragon stands nearly 27 ft tall and 13 ft around dragon is capable of carrying up to seven passengers to and front Earth orbit and Beyond but today it's carrying the four members of the Polaris Dawn crew and the crew is currently living and working in the top portion of the spacecraft that's that white section that you see there also known as the pressurized section this allows for the transport of people and environmentally sensitive cargo below that dragon's trunk it sits right below the pressurized section that can carry unpressurized cargo on resupply Mission and it remains attached to Dragon until before re-entry into Earth's atmosphere and as you can see about half the trunk is covered in solar panels those provide Power to Dragon during the flight the other half is the radiator Dragon itself is equipped with 16 Draco thrusters we got a really cool view of the four forward bulkhead ones firing earlier on this flight with lights on Earth behind you those are used to orient the spacecraft during the mission they also get used for apog and pery raise and low Maneuvers orbit adjustments and attitude control for the Eva the Draco are going to be used to reposition Dragon so the trunk is facing the Sun and they're also there to be used for reorientation during the space walk if needed in order to accommodate accommodate a spacewalk this is the first dragon to be outfitted with a Skywalker in place of the Koopa observation Dome the Skywalker that you see there looking up at it uh from the from basically from under underneath it um the Skywalker is a structure that is mounted to the top of the Dragon capsule and the astronauts will use this to assist in exiting and re-entering the spacecraft during their space block the team also added additional nitrogen tanks to assist in repressurization of the capsule after the Eva another new feature on Dragon is the addition of a motor plus hand holds and footh holds inside the spacecraft to help with opening and closing the hatch during The Space Walk This Dragon also o carrying what we are calling the starlink plug and pler making this the first mission on Dragon to use the starlink network in orbit inside a dragon is a router connected to a user terminal in Dragon's trunk and then this terminal is linked to a new plug-in player device that's mounted nearby while we're not using starlink for continuous coverage during this operation we've been testing its ability to establish and maintain laser Communications with our starlink satellites there in orbit that are below dragon dragon has proved to be quite a versatile spacecraft it can autonomously dock to the space station when outfitted with the ISS docking adapter and when it's intended for free flyer mode the docking ad adapter can be swapped out drag and you guys are welcome to pull them back aboard if you want space copies don't have uh ground station right now but we'll go ahead and bring cameras back on board so we get it when we do have ground stations quick coms there with SpaceX core uh from the Dragon capsule that was uh the crew just letting the folks here uh in Mission Control letting us know that it's okay to turn the onboard cameras back on once we have uh coverage for those cameras um but getting back to the different U configurations that we have for the Dragon capsule um I was talking about the docking adapter previously when the Dragon capsule is intended for free flyer mode docking adapter can be swapped out for a Koopa uh which is the one in the middle there and that is used for the best views that you can get while in orbit and then of course our newest option the Skywalker Hardware to support extra vehicular activities and that's what the crew is going to be using this morning so those are the current three ways that dragon can be configured to support different types of missions but hey you never know what's to come we always got something up Our Sleeve right now Mike crew one broke the record record for the longest space flight by a us crude vehicle surpassed the 84-day mark that was set by an Apollo capsule during that final flight to the Skylab space station in 1974 what was it like cuz we went over it you literally called Dragon home during that time they like to live in there so so first of all I got to say it's pretty exciting because uh the the dragon that they're using right now is the dragon that I lived in that took us to orbit uh yeah we affectionally called resilience uh and it was it was an amazing spacecraft uh it it from a standpoint of living inside it and um again it it a lot of room actually compared to some of the other crew quarters that we had on board and uh and and plus just uh you know being able to to uh spend all that time in it you know i' call my family every night before I go to bed and I'd be looking out the window uh at the Earth uh as as I was doing that it was very special did did any of them get jealous cuz you had the window seat well yeah there was a little bit of that certainly uh going on up there nice now as you mentioned this Dragon capsule that the inspiration excuse me that the Polaris Dawn crew is flying in was previously used uh really debuted on the crew One mission hence why you guys had the um honor of naming it in the first place but this capsule was also used for the inspiration for mission that uh Jared also commanded um what is your take on uh this being one spacecraft but supporting multiple missions I think it's fantastic it just shows the flexibility of the design that SpaceX made when uh when looking at the crew Dragon Vehicles so I I I think it's very exciting to see a vehicle that can that can go from one mission to the other and and quite frankly do it quite uh quickly as well I think I don't remember the exact timing uh from our mission and when we landed to win inspiration for launch but it wasn't a very long time and yet you were able to take that docking adapter off put the KO on in in a very short time which is also pretty impressive I actually have that noted here uh crew one took off in November of 20120 and inspiration 4 lifted off in September of 2021 that's that's a yeah we landed in May of 21 and So within that short period of time you reconfigured the vehicle and uh and were able to put that cou on and launch yeah very Prive your mission patch sticker is in the is in the capsule that they're in now and add their own sticker too as well all right well as you can imagine dragon has undergone some changes for this and with changes comes extensive testing for the mission and all the modifications that we made in preparation for today had to go through kind of their own test regimen yeah testing is a critical part of qualifying a spacecraft like Dragon for flight rigorous testing helps identify and mitigate potential risks verify system and component reliability and helps ensure that the designs meet the mission requirements there are many types of tests a spacecraft might undergo when qualifying for flight including structural thermal vacuum radiation software and Integrated Systems testing one of the tests the new Skywalker Hardware underwent is thermal vacuum testing this actually tested how Skywalker withstands the extreme temperature swings that it's going to see while it's in the vacuum of space and while Dragon was being put through all of its Paces the Polaris Dawn crew was going through the same SpaceX training uh as part of that we give to NASA astronauts they also had to train to perform their Eva though for basic training at SpaceX Hawthorne they trained on everything from orbital mechanics to just how to live and work in microgravity also ran through numerous simulations of what the full mission would look like while they were seated inside of our Dragon trainer in addition to ensuring that they're familiar with spacex's Falcon 9 rocket and dragon spacecraft the crew went through an extensive training regimen to build their physical endurance and mental toughness ensuring that they are well-rounded and prepared for space flight and today's Eva now switching gear is one of the coolest things designed in-house by SpaceX the Eva suit is all the functions of our original space suit with the added bonus of allowing astronauts to exit the spacecraft while in orbit and this Mission this Mission gives us a great opportunity to test our Eva suits in space building a base on the Moon and a city on Mars will require thousands of space suits so the development of this suit and the Eva performed on this Mission will be important steps toward a scalable design for space suits on future long duration missions as we mentioned SpaceX designs and manufactures our own suits and we have a little behind the scenes look for you something most people don't get to see the inside of our very own suit lab an Eva suit is an extra vehicular it suit which is a space suit that can go outside of the spacecraft to do a space walk we started with the Iva suit that we have the int vehicular activity suit as a kind of starting point and looked at it and said what would we have to change about this to be able to support a space walk so the first is mobility um the crew will have to do a lot of moving around inside a dragon to get outside and do The Space Walk we had to add in new joints um and new features in the suit to allow them enhance Mobility while the suit's pressurized when the member is pressur ized in the suit the soft portions of the suit become rigid they need actual flexure and rotational joints to allow them to move around it's kind of like a suit of armor made of fabric we innovated in flexure joints to allow easy bending at the elbows and the knees as well as a collapsible Rotator joint that exists on the shoulder which allows the suit to remain nearly fully soft but when pressurized is a rotational bearing the difference between the Iva and Eva suit is that on the Iva suit the zipper system location is in the inene uh but since we needed to have lots of Mobility on our Eva suit that was not the Preferred Choice by moving the zipper system from the inum to the waste we mitigated risk of the stress of the zipper and another big element was also the the thermal side of things the crew is obviously exposed to a much more extreme thermal environment during the Eva so we want to make sure that the inside of the suit is comfortable for them um and that as they interface with parts of the vehicle that that is safe for them to touch as well the Eva suit is built and designed here at SpaceX in Halton California we wanted to have something that's easy manufactured that we can handle here in house so we developed this new material so it's fabric based we actually added a new layer to the suit which we refer to as the Faraday layer and this is a inductive cage around the suit that Shields the suit from from external electric Fields the helmet on the Eva suit uh looks very similar to the Avia suit but is really an all new design of that helmet um it's much more robust from a thermal structural perspective since it will be taking more extreme temperatures we are really excited to introduce this new single pane visor helmet to the world of SPAC suits the Eva suit visor is made of polycarbonate and is coated with copper and I or indium T oxide these two Coatings together reflect the Sun away from the crew as well as reflecting infrared heat back to the crew when they are facing deep space our suit has a HUD or heads up display which is a small display screen in the helmet which is transparent which allows the crew to see through the display to have unfettered access during their Eva but it also provides critical Telemetry to the crew so pressure temperature relative humidity we're trying to improve the technology and streamline it in one way and at the same time we're also trying to get it more and more manufacturable with each generation the ultimate goal is that you can put on a spacit and go out and get work done anywhere in the solar system um and not feel like you're wearing anything more than you normally wear every day we also had a chance to talk to the SpaceX team that develops some of the hardware and procedures for our first Space Walk let's hear what they had to say Eva stands for extra retail particular activity and it's any sort of operation in space where a human is getting out of the spacecraft so in the case of Polaris Dawn we're going to be testing the mobility of the suit we're going to see if the inspace operation matches the training we've done here in Hawthorne there's really a lot of different things that can happen during an Eva and this is the first step for Dragon and SpaceX when I first started working at SpaceX I never thought I'd be training a crew to do an Eva it's brand new it's so unique we've never done anything like this before and so we wanted to make sure we had the best possible training program for this Mission we want to see if we can train a space walk on earth in a way that's representative of what it feels like in space even though only two people are going to be going outside during this first Eva all four crew will be in Eva suits going down to vacuum Dragon was always designed to vent to full vacuum but we've never taken full Dragon capsule down to vacuum and this will be the first time we do it in space we actually put crew into a chamber at Johnson Space Center in Houston and had them live the exact profile that they will experience and making sure that no one actually experienced uh decompression sickness we have a couple new training assets for player stwn to train the Eva specifically the suspension system that we have is situated on top of the platform of our capsule Simulator the lines drop through the hatch they attach to a single crew member inside the capsule we can lift them up and get them situated so that they can ESS the capsule and perform their tasks at Skywalker the mobility Aid the Skywalker what's amazing to me is a lot of people are going to think it's a metallic structure just bolted to the top of dragon but a lot of development effort testing went into the Skywalker so we actually used similar technology as we have in the super Draco Chambers to apply a thermal barrier coating to the outside of the Skywalker that is going to be a really really amazing Mobility eight on the front end of dragon we also developed a sideways simulator so we flip the hatch on its side in the event the hatch fails to close they can manually close the hatch we had them do that in a sideways suspension system so gravity isn't helping them close or helping them open that hatch mechanism it's new develop M for Dragon its new development for SpaceX and the industry as a whole so this is a great example of where polaron is forcing the team to innovate in a way that adds safety and reliability to every dragon mission going forward that's this huge challenge for us to go solve but that's also an opportunity for us to solve the problems that we have to go figure out anyway for our larger goals like putting people on Mars the Piston objectives are the first step towards that ultimate flight with with humans inside at Starship which is right along the SpaceX development paths that that we have towards getting to the moon and Mars love seeing how not only the suit but the space operations for the Eva itself uh came together and were developed uh now we are still counting down to the spacewalk this morning uh the crew is or excuse me the crew on board is completing final fit-ups and we're going to be standing by for seat rotation and suit leak checks so we're continuing to truck along to the the the main event uh now Mike you obviously went through some of the suitup process that we saw in that package in terms of um the the development of the suit and how it's custom fitted for each individual and that's that's the same case for an Eva suit so maybe you can share with us what that experience was like yeah it it's extremely important uh to to have a suit that fits whether again it's the Iva the EV Eva suit or the Emu that we wear with NASA when we go out on the spacewalks and the reason for that is because if it doesn't fit right it can be extremely uncomfortable you can get what you call hot spots or uh there can be a a a place where the a crease when it gets pressurized can really put a a uh a hard point on your arm or something of that nature so having a good suit fit check is extremely important and and it's one of the things that was kind of fun as well because you get to spend a lot of time with the the suit team here with Chris and Eric they're fantastic and and I mean just over the years they've gained so much experience and they can really help you hone in on what a the really good fitting suit is is like with just the way they ask the questions and lead you through that that process wow what are what are kind of The Sensational differences from being in like the ivac because a a lot of times the Iva suit when it gets pressurized you know it fills up but you're still in like a pressured environment with Eva suit you're in the vacuum right and so like what's it kind of like yeah so you know that Iva suit it has a different purpose right and that the purpose of that Iva suit is to Keep Us Alive in the event of some type of an emergency that might happen during a launch or a landing and and so that's that case where either you have a fire or you have a depress event and so that suit's going to pressurize and so in that case we're not as worried about like the mobility of of the suit you just want to get home and and do it in a safe way and so you need to have enough Mobility to still be able to control the spacecraft and and do the things you need to do but but you're just not as worried about it because you're not trying to perform a maintenance activity or or something like that when you're going down on the on a on a spacewalk and and so I think that's that's one of the the biggest differences between the Iva suit and the Eva suit is just what the purpose of it is and what you're trying to do with it yeah that feedback loop um is so important to be able to communicate what what feels good what doesn't U because I imagine um you know as you're out there and having to perform you know as you mentioned maintenance activities uh among other things that the functionality of your body is critical to to to perform those it really is and probably one of the hardest I think parts of the suit to design is the gloves right because absolutely you know you hear us use the term it fits like a glove right we use that a lot but but you don't realize how much you use your hands when you're outside on a space walk as opposed to say your feet when you're you know because in space we don't use our feet our legs as much as we do our hands and and so when you're in a a pressurized suit like that and you're constantly grabbing and reaching you are overcoming the pressure of the suit and your hands can get just exhausted and you can get those hot spots um I had some issues with my emu gloves when I first started training at Nasa and I would actually get what's called d ination on my fingernails yeah and and so there's just little things like that that it really matters how well that suit fits and and how well it functions and and so uh it you don't realize how important that is sometimes yeah um now we are going to be stepping into suit leak check soon um can you share with us a little bit about what that process uh entails um and and and more importantly because you you've actually experienced what it feels like to go through suit leag checks what what that experience is like extremely important part of the whole process right because before you take the cabin in this case all the way down to vacuum you want to make sure that your suit is maintaining the pressure that it needs to and and so it's a it it's a not a very long process it's usually just you know a few minutes to two or three minutes um and you know the the interesting part is if you don't pass that Lea check what do you do next and and so there's always usually procedures associated with that as well start checking your zipper start checking how you've closed things up did you not get something sealed quite right um and and so it's always a good point in the mission when uh whether it's on the Launchpad getting ready whether it's in the airlock getting ready to go out the door when you when you hear that yeah good lead check uh because now you know that you're ready to go so today's going to be kind of unique because all four of our crew members are going to be like doing The Space Walk they're all going to be exposed to the vacuum of space but I mean even when you did space box it's never a solo act right like you're always out there with a partner you you are it's uh it's extremely important in fact one of the hardest parts about our training for space walks is what we call incapacitated crew and so you need to always be able to get your crewmate back into the airlock if something should happen if uh if they should no longer be conscious and and something of that nature and so we we actually do spend quite a bit of time and that's why it's extremely important for us to go out in pairs because things can go wrong um and and so you want to be prepared for those those moments yeah uh that's a great Point Dan to make that um while only Jared and Sarah are going to be somewhat exiting the spacecraft um all four crew members are going to be exposed to the vacuum of space and it's actually going to set a new record for most number of people exposed to uh or not them without a suit but like yeah in the vacuum of gravity all at the same time yeah that's actually interesting I never I never actually thought of that piece of this Mission and the fact that you're going to have four people on a spacewalk I I know at one point on a shuttle mission we had three y three folks outside on a on a spacewalk um and so yeah that's a that's a big deal and and kind of exciting you know one of the one of the things we do on the on the space station of course is We Have astronauts that are still inside and if we do get into those emergency situations they're there prepared to help us uh get back into the airlock and and uh and get unsuited and and things of that nature so of course when you have all the crew it just makes you think about those emergency situations probably in a little bit different way than we than we do on station yeah and hey if you're just tuning in we are still waiting to really kick off our spacewalk today so right now the crew is inside the spacecraft they're getting suited up we should be hearing some coms from them pretty soon and then space XX Dragon um EV one is completing glove zipper closures but this time we are ready for seat [Music] rotation copy that for seat rotation can you confirm crew is ready with the current gloves at props all right I I guess they just needed me to to say it was coming soon and then and then there it is uh but uh we are going to hear the seat rotation coming up soon again they're in their recline position and I'll standby well get some of seat copy standing by so they're going to get those seats rotated and then we're then we're pretty much going to be ready to start getting into things and uh our Eva is going to officially start when we start flowing O2 into those suits um and so that'll kind of start our clock we're going to be showing you some of the Telemetry so all those numbers the bottom of your screen you've got a couple right now that want all the way in the bottom left corner that's your dragon that's your dragon cabin pressure that's in PSI ready for seat rotation SpaceX copies initiating seat rotation great news there that's going to help give the crew a little bit more room to move around uh during The Space Walk and after we get through this seat rotation will be able to perform those suit leak checks that we were just talking about yeah before they do that they'll do what's called a tear so it's kind of like if you're ever using a scale you zero out the scale before you put something on it that's essentially what we're doing with the suits they'll get like a baseline reading and then as we start to actually pressurize the suits we'll be able to measure that against the Baseline make sure everybody's got basically a nice seal before we start that vent yeah that one's pretty important that was pretty important yeah um so a lot of that's coming up again some of the data on your screen you've got cabin pressure you've got suit pressure Dragon SpaceX seat rotation complete and nominal all right C rotations complete so now they're going to start doing that tear getting readyy and can I get a confirmation of completion for the call out in 2 decimal 18 say complete with 2 copy at this time you are go to step into section three and tear suit deers [Music] now just a quick reminder in case if you missed the top of um the show we're we're going to be referring to the crew a little differently for the Eva activity um than we were previously so we heard Anna uh talk ev1 that was referring to Jared so his basically his call sign for this uh spacewalk operation is ev1 um Sarah's call sign will be ev2 Anna will be support 2 and uh Scott will be support one uh also Scott and Sarah are switching seats uh I perhaps they already have copy standby for HUD power for pressure centor check outs okay so our suit tear completed so next up is going to be the HUD checkout so the HUD your heads up display very excited about this really really excited about this and Mike I'd love to kind of get your perspective on this real quick we do have on your screen though that's your seat order so uh you've got ev1 Jared is in that seat he's going to be in that seat right now but once we actually get ready to open the hatch and everything he's going to be positioned kind of over by the hatch and then Sarah ev2 is going to be in one of those Center seats then you'll have Anna and kid on either side Dragon SpaceX suit Huds powered report results of primary sensor HUD checks and three decimal 2 so again that's our that's our SE layout we just heard the Huds are powered on so they've got heads up displays actually being kind of projected on their visor in their helmet which if you if you've ever seen space suits it's always kind of felt like that's that Space Age Technology that we're missing because Mike you guys use kind of a a a simpler but a little unorthodox way to see like your suit data yeah that that's right Dan uh of course the the suits and check complete ninous copying the backup sensors stand by to repeat H checks so of course the suits that we use for the the space walks on station are a little bit older they've been around for for quite a while and and so some of this uh technology uh you know look it's our first live views inside Dragon resilience for this morning that's fantastic yeah I think this is the definition of chilling yeah so there out of his seat that's Commander Jared uh who like I mentioned before will be referred to as ev1 behind him we can see already in his new seat uh pilot Scott kid potit uh he will be support one and then moving around in front of us is Sarah who will be ev2 and then just out of view underneath the camera but I think you can see her visor is um Anna Menan who is support to Dragon SpaceX we're on backup sensors repeat HUD checks the crew is going to check out those heads up display one more time real quick check back good returning to primary standby for helmet camera check out on that heads up display they'll be able to see the O2 flow timer that's kind of like our mission clock essentially like once the O2 is started to flow to their seats and they know they've got about an hour and 50 minutes just under two hours for the whole time they'll be able to see their suit pressure temperature basically it's a way to kind of keep an eye on things and we were talking about it a little bit Mike but on the Emu is a little bit different yeah the Emu is certainly different uh a lot of that kind of information is on a on a display right in front of you that you have to kind of look down to see and it it can be pretty challenging to see in fact a lot of the information you have to use a mirror on your wrist uh to be able to to read it and know what you're what you're controlling as well uh you mentioned the time timer of course we don't have that kind of information on on ours and I'm not sure I'd want to know that cuz I'd feel the pressure of I got to get a lot of things done running out of time yeah all right um so there they're going through these HUD checkouts again pretty soon Dragon Space X powering on helmet cams we're going to get the helmet cams powered on again give you that kind of look right over their shoulders yeah pretty excited for these we've uh seen them utilized during the training uh sessions that the crew has undergone and we're so excited to to see them live today yeah I I tell you the helmet cameras I mean it's going to be fantastic views right that we're all going to love but but there's also a very important U role for those cameras as well like when we have the same thing we have helmet cameras with the emus and what it allows is your ground team Dragon SpaceX suit cameras powered confirm good health so it really allows your ground teams to to kind of be able to see what you're doing and just good video on and almost double check your work copy checkouts complete Huds will remain powered proceed to step three decimal SE 3 operations review through three decimal 8 report one complete all right so we got through HUD checks we got cameras on powered ready to go so right now the crew is going to go through they're going to do kind of a final review of all of their procedures likee you talked about this a little bit like these things are so choreographed because even if you couldn't see the clock like you're on the clock so you've got to you've really got to make the most out of like every single second you're doing one of these you do and and of course you see that with with today's space walk as well space X repeating checkouts are complete Huds are going to remain powered proceed to step 3 decimal 3 operations review through 3 deal 8 and Report went complete the and and the reason it's so choreographed and important is because you only have so much time outside right you only have so many consumables that allow you to go out there and so you want to take advantage of all of that you want to have every step very well scripted so that so that there's not a lot of wasted time now that being said it is nice when you're out there once in a while to just kind of take a moment look around enjoy the views kind of trying to absorb where you actually are which uh can be pretty incredible as well every every once in a while guys I'm a little tired I'm going to take a minute that's right I need to take see my house from here that's right yeah all right but like it's it's awesome we're seeing the crew inside we're getting close to the start of today's spacewalk we're going to start flowing O2 to the suits and that's when our clock's going to start right now they're just doing kind of final cabin configurations they're going to check the lighting uh they're going to make sure that their umbilicals are in the right spot that's one of the things you'll see that's actually one of the the the roles that our support uh crew members are really going to that's kind of one of their one of their primary jobs during The Space Walk is to make manage those umbilicals for you guys Mike you had one that's what plugs into kind of the leg in your suit and that's what's providing like the breathing gas coms connections all of that stuff uh for the spacewalk today it's a little bit different this one uh that they're going to be using has some tethers in it um for Anna or for Sarah and um Jared it's about 12T long so it's like about double double the length of what you guys are so it's dual purp right it's it's providing them the the air and the cooling that they need while they're out on the spacewalk uh but it's also providing that safety piece right so that if uh if something should happen they should slip or um that that they're not going to go floating off into space with the Emu uh that we use on the space station we actually you know all of those consumables are a part of the suit itself and we have a separate safety tether that the first thing we do when we open that hatch and we go out is is we hook up that safety tether and it's an 85 ft reel that uh as you're moving around it it goes out with you to again protect for that crazy moment when maybe uh an emergency happens and you come off station how how hard was it to manage all of those tethers I feel like every time I watched it was like there's no way in heck that this thing isn't getting snagged on something no you're absolutely right because everything and and you talked earlier about making sure there was no loose items in the cockpit right because when you open that that hatch uh things are going to want to float away if they're not tied down or stored or anything like that so when we go out on a spacewalk not only do we keep us Tethered to the spacecraft but any tool any part that we take out with us also has to be tethered and it can be quite a challenge to manage all you'll open up a bag and there's there's 10 pieces of Hardware in there with 10 different tethers and they get all tangled up and and it can really be pretty challenging it's important though um we simplified that a little bit for this Mission um we actually basically built in that tether into the umbilical one of which you can see actually they floating uh under Jared's right arm so not only does that Pro provide airf flow and comms and uh all the normal connections that we have in the in the umbilicals but we also added that that strength uh to provide that protection yeah and and the managing of that tether is extremely important because you know as they go out if it can get tangled up and you actually see Sarah there kind of moving around right it's it's very easy in in this environment where you're [Music] floating Dragon Eva off you complete who are in position to Eva start nice excellent C position but you saw Sarah kind of move the tether out of the way and the part of that is that's actually impacting go to command box push talk all seats [Music] C and so this will this will be one of the unique things about the space walk today it'll it'll feel familiar if you've ever if you watch some of Mike space walks the crew is going to go over to what's called VX is set go the to check1 to check ev2 to check support one con check support two com check SpaceX copies all good coms all [Music] four so essentially now all of our crew are on open mics they can all talk and hear each other and they can talk to the ground and so you're going to hear a lot more chatter start to pick up uh once we start the suit pressurization you're going to hear almost like a sound that's just the air starting to flow into their suit um how how loud does it get inside your suit it it actually is quite loud that air flow is just constantly which is a good thing right because not only is it providing you the oxygen but it's also helping get rid of that CO2 that you're breathing out so you want that air flow uh to be constantly going and and so you always are hearing that fan uh that that's uh making that happen and so that is that is certainly pretty important and the Box thing I got to say you know it's nice that you don't have to push a button when you're outside there to to talk Dragon SpaceX we're about 90 seconds from E initiation got some fist bumps going on yeah and we just heard we're about 90 seconds from Eva initiations so we should see them get the go to close their visors and then they're going to open up one of the O2 valves on their suits to start the suit Purge and that's going to be the official start of our space walk today so we're we'll get through the the final goes and then we'll see those visors get closed oxygen start flowing and we'll be off I love how everyone looks so calm and collected right now I think that's a a a great visualization of just all the extensive training that they've gone through to get to this point this has been years in the making um I'm sure they're excited uh but everyone's focused it it it is an interesting time right now right because one of the hardest parts I always found about Dragon SpaceX SpaceX is go for Space Walk operations report visor down ready for secondary O2 flow initiation and crew is go for [Music] spacewater verify your visors are closed secondary O2 is open [Music] and that you are the ev1 is go B2 is go support one is go support two is go [Music] Dragon SpaceX initiating secondary [Music] O2 and with that news our Eva has [Music] begun so you're you're going to hear it referred to as primary and secondary O2 primary is going to be that primary flow of oxygen to pressurized secondary is largely putting oxygen into their suits to help with cooling but secondary is the first one we turn on and so our O2 flow timer has started Eva start at 3:12 a.m. Pacific I'll do the math on UTC in a little bit so this first this first operation or this first step in the operation is a suit Purge so inside there's suit obviously when the visor is still open it's still a nitrox environment it's the same as the cabin uh and since they're going to be at a lower pressure than what you can basically live at with with oxygen levels um they're going to be on pure2 they're going to be a 100% oxygen environment and I mean you guys were kind of in the same thing and it's it's because like your suit can't you can't move a suit around at 14.7 PSI can you maybe you can but no that would be pretty that'd be pretty tough to do and and as we talked about earlier that's why that Mobility is so important because uh when that suit is pressurized like that it it can be challenging to move around absolutely so here on your screen we can see the polaron crew now with their visors down the Eva has begun we are beginning to flow that uh O2 through now we will of course bring these views to you as we have them but due to ground station coverage they do come in and out here and there um but every moment that we can we will certainly be sharing these with you um I also wanted to point out quickly that the the the window near kids feet was so much brighter than it was uh just even five minutes ago we're going to be seeing that uh in start contrast as soon as we get uh the Eva or with the hatch open and ev1 out there yeah it's kind of interesting you you you mention that because as you're going around the earth as fast as you are right in in 30 minutes or 45 minutes or so you can be passing in and out of that sun and and going into Shadow and and so that brings its challenges as as well because the temperature um can change pretty drastically just in those transitions from night to to Daylight and and so there's a there's a it's an interesting moment when you're passing through through that time that's actually one of uh the reasons that the visors have this new coating on them different than when you wore the a similar helmet um that coating actually helps to insulate the individual inside the suit so when they're looking look at the sun dragon Space X a reminder after the initiation of primary O2 flow ev1 ev2 will need to adjust Vox threshold low following primary O2 flow [Music] initiation maybe one copies BBE two copies Dragon SpaceX secondary flow Purge complete close secondary O2 Valves and report ready for suit [Music] pressurization ab1 closed ab2 closed report one closed report two closed facex dragon is ready for seat pressurization initiating primary [Music] O2 this is normal this is with the air flow coming through uh the crew members are on Vox meaning uh that their the microphone is on the whole time so Sarah and Jared are going to be adjusting their audio levels um as this flow continues to to help regulate that yeah the the the Vox will kind of attenuate so it'll it'll sound like this now but as we get through The Space Walk it'll kind of come down and you'll just hear voices a little bit more clearly uh their their voices are actually going to change too like did that did that happen to you did that throw you Mike the first time you heard that it absolutely did yeah cuz you're you're you're talking and you're going who is that right you don't realize how how much different it can sound um your voice can sound in that lower pressure environment yeah speaking of lower pressure we can uh we can see the pressure changing there with the Telemetry in the bottom left hand side of the screen so we can see that suit pressure going up um and we're able to keep tabs there um as well with the dragon pressure so Dragon uh on the far left Circle that's the pressure within the cabin and then suit obviously that's the pressure within the suits so we'll be actually be able to and I think we've kind of been able to see it already um that these suits will inflate a little bit um look a little different and we were talking about the the visors before so when they're in the sunlight that coating will help keep them cool and not overheat them and then when they're in Shadow it'll help keep them warm so uh and it's also like your sunglasses as well right serves that purpose all right so at this moment the suits are getting their primary pressurization this takes about 3 and a half minutes a little bit less and then we're going to go through those actual suit leak checks I the crew will probably get a reminder they have to stay really still when we do those leak checks and I always was kind of wondering like why the heck and like if you if you bend your arms you're actually going to start you know changing the volume inside the suit that'll cause pressure spikes and so that's right you got to stay really still yep and then after after we get through the leak checks we're going to go through kind of that final pre-breathe uh where they're going to hang out in that 100% O2 environment just to continue purging all of that excess nitrogen um second ev1 open one open support two open and right there they they finished the purge and they did a quick uh reinitiation of that secondary flow check [Music] give me one cl close these handles that we see Jared holding on to these were one of the additions uh or uh customizations for this mission that we talked about earlier support contact we got you all right cop got Dragon Space X beginning the check evaluation and then still checks once again that background noise is expected um that is the microphones and the flow of air uh within the suits so we're trying to stay quiet to uh along with you listen in on what the crew coms uh are as they go through um we're also uh going to get views in and out as we mentioned before due to uh ground station coverage and it is it is a little bit tough to hear we just heard though that we got four good leak checks on their suits and now they're going to be in this final suited pre breath and so again this is going to last about 19 or so minutes uh and this is just to do kind of that final get all of the excess nitrogen out um and we started pre-breathe just two two hours after they got on orbit just by you know gradually lowering the pressure and I mean preb that that's something that kind of evolved over time with the space station where where were you when you were doing your space walk yeah so we were past the kind of the camp out phase of pre- breath U but that's how we used to do it it's very similar to what what the polaron crew has been doing over the last couple of days we'd actually have uh astronauts stay inside the crew lock overnight at a lower pressure just like they did when they first got on orbit now we've moved on to we do it the day of it still is a long day we start about six hours prior to going out the door uh but it's not two days prior it's worth noting uh along the lines of training and how the crew prepared for this mission that all four of our Polaris da crew members uh and some additional Polaris and SpaceX crew members actually went into um a a vacuum chamber and tested these suits out and spent uh a bit of time at lower pressure just to help learn what that feels like and get used to it well and I think the other thing that's important about that is it's real right it's it's the first time that you're in that suit and it's actually a vacuum around you right and there's just something mentally that I think is important to put people through those moments before you actually have to experience the first time in space yep we we saw some of the unique ways we train the crew for this and I mean training for space stations space walks I'm still really upset I never got in the pool uh that looks like one of the coolest like parts of being an astronaut is like not being in space but just doing some of those training yeah Dan I I I tell you I can still remember the first time I stuck my head under water not in the in the soup but in the for diving but you can hear the calms of of everything that's going on through the water like that and it just gives me goosebumps to think about think about that it was a really neat environment but it looks like these guys had a pretty neat way to train as well with the uh the the harness that would hoist them up and out and and all that that's that's pretty impressive yeah um we definitely created some rigorous uh new training for the best we could simulate an Eva while still on Earth um with hoists and uh you know it was um it was a lot of fun to watch them train in minutes so our C just called up we'll get we'll get views back on board in about 3 minutes as Kate talked about earlier we're using ground stations for our video coverage all of our communication with the astronauts are through tedris so tracking a data relay satellites so we have we'll have constant audio but that video we need those ground stations uh but right now they're just they're in that pre-breathe uh that final pre-breathe still we started our space walk about 13 minutes ago we we initiated O2 flow to the suits the time was 3:12 a.m. Pacific 12 10:12 UTC I did some quick map took me took me 13 minutes to do it but I did it um so we're once they're through this pre-breathe we're going to start getting into some really exciting parts of the Space Walk and and then after after we get to the pre-breathe we're going to get to cabin vents so you know what's what's going through your head when you're like man it's happening the A's going out it's really happening it's happening yeah I I tell you it is a long process to get to this point right they've been prepping for this for two days right and and one of the hardest things I found about the space walks is the waiting hurry up and wait hurry up and wait right you are so ready to to go out and to do this Mission and and to go out that hatch and it just takes time and I think that's one of the things you talked about my fifth versus my first your fifth you kind of understand how long it's going to take you have a better appreciation for how long it's going to take and so you literally find yourself in these moments when when you're kind of waiting through this pre-breathe or you're waiting for the airlock to depressurize just kind of find yourself just floating there kind of zoning out trying to keep yourself calm and relaxed and and until that moment when it's it's game it's game time yeah now just a quick mention we about a minute out until we uh get those views back uh inside the cabin um The View that we had previously was our Dragon tracker which uh if you want to see where Dragon is you can actually look that up as well um we have it on our website spacex.com slf Dash Dragon um but yeah just as a reminder uh our our crew they are in there designated or well Jared's not but um the yeah um our our crew members basically Sarah and kid have switched their seats for the Eva um we saw we last time we were able to see inside the cabin we saw Jared awaiting um to open the hatch so he wasn't in his Commander seat but uh Sarah is now sitting in Scott's pilot seat also known as seat three um and then Anna is on the far left side and Scott is on the oh yeah we can see it there on the far on the far right side um and also just a reminder uh their their call signs for these Eva operations um Anna being support two kid being support one and then Sarah being ev2 and Jared ev1 representing uh that Jared will exit first uh do his activities which includ just some Mobility testing of the suit uh and then Sarah will go out and perform the exact same uh testing once Jared comes in um meanwhile uh kid and Anna will function as the eyes and ears uh they will be performing uh their own uh list of operations during uh or their own list of tasks during the Eva so while Sarah and Jared are going to be the ones that are you know partially egressing the capsule once that uh forward uh door is open open uh kid and uh Anna will also be performing in Eva in their own right that's great and we talked about it earlier first time for people exposed to the vacuum of space like that's there's a lot of first in this that's going to be a really cool first not just for us and dragon um but we are going to be getting views back really soon we're again just in that final pre-breathe step right now and then we're going to start venting uh venting Dragon down to near vacuum so we're going to have a couple of different valves that are going to open up and the atmosphere inside dragon is going to start going overboard out into the vacuum of space now the crew the ground they can control they can pause that cabin venting if they need to uh we can pause and resume the most likely reason is for ear Equalization is again you're you're going through a lot of pressure changes anytime you do a space walk and so if you've ever flown on an airplane and your ears popped you've experienced just a little bit of what they might be going through right now uh once we start cabin venting if terminate or abort that the spacewalk during that venting we cannot start again we talked a little bit earlier about how consumables are like the thing that really drives you uh and for us we don't have a great big air lock with this with you know a full station worth of oxygen and stuff like that um so T1 go initiating we go that is great news exting so that breathing of incre a pre-breathe where they were breathing increased oxygen we just heard that uh they're good they all all four crew members gave the go uh so now we're going to vent the cabin yeah in in total this will take in total this will take about eight minutes and you can this the graphics you see in your screen that's live Telemetry everybody so you can see the pressure inside Dragon starting to tick down you're going to see the sou pressure tick down as well is what we're really trying to maintain is a pressure differential and so with these suits we're going to be hovering right around five or so you might see about 4.9 to 5.1 5.2 um it'll be about 4.9 and then we'll probably see it go up a little bit uh when they reinitiate the secondary flow at and you talked about that uh about five PSIs with the suit will be we're actually a little bit lower in the Emu and so we've talked a lot about Mobility that difference between we're at 4.2 and they're going to be at five it can actually make quite a bit of difference just in how hard it can be to move the suit around Etc yeah this crew got to and that's something we can simulate you know on in a vacuum chamber or even just uh in 14.7 you can you can simulate that that differential pressure getting call us from the crew they're they're monitoring along we're going to hear that kind of we're going to hear that chorus pretty frequently where you do those kind of frequent most like check-ins and I know you guys did something kind of similar where like you would have to pause and you know check your gloves that kind of stuff we we did I I will tell you one of the interesting things watching this uh live right now the difference is how quickly the depressurization is happening here versus uh what my experience was and and so you talked about being able to clear your ears and all that you're not giving a lot of time for your you're not giving a lot of time for your your ears to adapt to that lower pressure so this this is seems pretty quick to me yeah break breaking new ground with this new suits new operations for everything we're at about 4.5 we're going to see that tick down it's going to get down to just under one and it's not going to go all the way down um and then what we'll actually see is we've got a capability to open the hatch automatically we got a motor in it U but Jared's actually going to unlatch it and he's going to give it a little tub to kind of break the seal break this any of the kind of the stick in the hatch itself and that's going to kind of take the capsule down to its final vent before Sarah who's at the displays she's going to command the hatch to actually open um yeah that's a good point and you know there's there will be slightly more pressure inside the capsule so really just helping presses look good copy is four so Jared really can't open the hatch all in one f ID motion so we will see him uh release that that pressure slightly um before being able to open it completely and I think one of the important things you guys I think I talked earlier about you put some more um restraint devices inside the capsule from when I flew on it and that's extremely important because there's going to be some force that Jared's going to have to be pulling down on and he needs to be able to Anchor his feet somehow um otherwise he's going to pull and it's not going to go anywhere and so the the new restraint Dev is in there we're going to see how important that's going to become here when he tries to open that hatch yeah yeah that's that's one of the things that's why we have Skywalker out there we've we've talked about how kind of similar to to Gemini when they were first kind of stretching their legs but important to remember we've got that 50 or 60 years of space flight history that we're able to draw these are new suits this is a new operation this is to you know work out all the Kinks and really test us for the first time but we're going into this with a whole lot more information than they had back then we know you need handrails it's going to get real hard real quick that's right that's right yep we did we did also hear uh dragons moving into its uh it's Eva orientation essentially we're going to point the trunk at the sun under 3 PSI I think it's also interesting you notice that the depressurization has slowed down yes a little bit right so as we get to this lower pressure it's it's just taking it longer for that remaining little bit of air to to uh go out through the vents and ev1 time check ev1 M and clear M and clear as well also hear the Vox starting to adjust its levels that that flow of oxygen has not stopped but the microphone's kind of adjusted and it's getting a little bit clearer and yeah keep keep an ear out you might hear their voices start to like tener down a little bit I do think that's a an important Point Dan that how important Comm is yeah right and and when it's compromised a little bit just by that extra air flow and the Box not keeping up with it right away uh how challenging it was just to hear those calls and they can be some pretty important calls so of course uh Comm is is just critical we can see Dragon capsule now approaching close to 2 psia like Dan mentioned earlier that's going to get to just under one it's incredible to think that uh you know the Dragon capsule in all of its power and glory and awesomeness the the new capsule is around their bodies right that that is what is going to protect them um from the vacuum of space and uh you know just seeing how even though it's puffed up and we know that it's uh you know holding that pressure it still looks so cool for lack of a better word yeah you really have four Mini Spa or spaceships in there PSI I guess that means we have four aliens in there too yeah that's right Dron SpaceX the PSI from hatch operating pressure we have a tedris Handover in 2 minutes we are going to wait until after the tedris Handover to command into Hatch Open Press yeah I think you heard that the the teed's Handover so there's going to be a a short period of time there where they're out of Comm and we're at it's kind of interesting because we're at a very critical phase as well well and so you want to make sure you have all the data and uh and the ability to talk to the astronauts before you actually take that next critical step we'll see it we're seeing that pressure continue to take down Dragon originally designed to be able to still operate in a vacuum that was some of the emergency situations I know you trained for Mike we did make some modifications to this one uh to essentially turn Dragon into a functional airlock um we added some additional uh vent paths um we do use like some of the same ones that you guys use to like pressurize the vestibule and stuff like that um that are actually in the hatch but we've got a we've got an extra one in there to to be able to essentially do that deess as quickly as we did uh but we're going to we're going to see that get down to a little under one and then we're going to see Jared kind of jump into action he's going to unlatch the hatch and then he's going to give it a little pull to break the initial S and then we're going to be able to uh see SAR C all look good now it's one thing to note that while we have been progressing through this pretty quickly we did have the capability to pause if any of the four crew members needed to uh you know take a moment to you know let their ears um come to equilibrium or just kind of get comfortable again um we did have that option but everything has been going really well so far we haven't had uh to to pause cabin venting and if you're just tuning in heck of a time to do it we're about a little under 28 minutes into the uh into the spacewalk today which again that started when we started flowing O2 to the suits of the crew members that was at 312 Pacific 1012 UTC we did just heard that dragon's now in its Eva attitude so again we've got we've got dragon's trunk pointing towards the Sun that was SpaceX core Arthur Al just letting the crew know uh that where the cameras are on inside and uh basically which camera is is looking at them it's it's so fun to hear Arthur's voice because he was actually a part of our mission as well in fact Arthur was an intern started out as an intern when we were first uh starting the training and and so now to see him as a as a core and uh is is pretty neat very similar to Sarah who also started as an intern yes yeah right we're coming up on one PSI you might see you saw the light change a little bit through that window as we're in our Eva position trunk facing the sun that's going to help us with thermal uh inside the capsule and on the cruise suits also going to make sure we're maintaining that that optimal pointing for communications with the tedris saddle lights uh once the hatch is open we're going to disable any of the Draco thrusters that point forward CU you know want thrusters firing off when a crew member's outside we're at one you can see the Su pressure is ticked down to there's about 4.7 difference between the suit and the ambient cabin there in Dragon that umbilical that you see there uh just to the side of Jared that will continue to flow the air into his suit as well as provide Telemetry and Communications connection that's also where we have the um safety harness built in as well so it's able to Dragon SpaceX T Pressure below hatch operating limit standby for transition to hatch open prep here we go Mike did you get to open the hatch I did did yes yeah when you when you go out as uh FR SpaceX hatch open prep confir to open hatch that ISX copies Dragon you go to open hatch exited open m as you mentioned before that continuous communication as you can hear we do have a crowd Gathering outside of Mission Control uh here in hawthor in their excitement somebody dropped a cup we can see our commander Jared isaacman now turning the crank which allows the uh that top hatch to open we'll see him give it uh a pretty heavy uh hatches visually IND copies stand by should see him give that hatch a pretty strong jolt to release that stion hatch is now latched as Mike talked about we see him getting his feet getting his feet set that's right Dan you ask if I got open in the hatch so when you go out a zv1 just like Jared here a zv1 that's that's typically the role for for you to open that hatch and you guys have to draw straws fight ever again it's exciting it is it's very exciting yeah now for those of you that have just recently joined as you can see we have successfully depressurized the Dragon capsule uh down to zero psia you see that in the bottom left hand side bottom left corner of your screen um are four polaron crew members um have uh gone through the uh O2 flow and we see Commander Jared um isaacman now standing by uh to open that top hatch the nose cone is already open it opened just shortly after uh the crew got into orbit uh so Dragon Space X Target pressure reached SpaceX I'm on feing the hatch now Jared now opening Dragon resilience into so we saw some motion on the hatch again he's just giving it kind of that initial tug and then Sarah gets to push the button to swing that hatch open much more movement there on the forward hatch this supp be pretty exciting for Jared because that center part of dragon Space X that's a good brace we're going to have you repeat the operation center of the hatch actually has a window is copy give it another hat copy we we see it looking out that tiny window there in the forward hatch knowing he is going to have a much bigger window in just minutes Dragon space xent complete ev1 return to seat transitioning back under the display so again one of the reasons we had Jared do that was to Dragon Space X we're actually watching that hatch we're going to have you repeat the last operation sounds like they're going to have him repeat them one of the reasons we're doing that is just to kind of vent any of that residual atmosphere and ev1 you are go for manual hatch open sounds like like we got our first audible of the day is we said that we can open the hatch open the hatch we could open the hatch man we could open the hatch automatically or we can do it manually and so they just gave Jared the go to open that hatch manually so we we just went out of ground station reach so we'll get the views back we'll get the views back real shortly uh and then the the hatch will get see a hatch open hopefully we see it yeah hopefully we see a hatch open hatch is open Tex copies hatch open that is fantastic news uh for those that1 I'm looking at your seals initial view looks pretty good copy on report yeah that seal that you just heard I'm talking about it's such a important part for the end of the Eva right so that when they close that hatch again you get a good get a good seal open there is our first view of the forward hatch wide open to space hat ex if you just jumped in we are 38 minutes into today's spacewalk and the hatch is open on Dragon first view from a C looking out Dragon Space X we see installed ev1 is go to continue that structure you see there is copies we with you in your helmet C once again this helmet cam what we that structure we see is the the space walker this is Jared now egressing through the forward hatch of dragon resilience these are the first views of the first ever commercial spacewalk I'm at the bottom of the mobility possessive I have a feeling the crowd is about to go wild stex back at home we all have a lot of work to do but from here first sure looks like a perfect world [Music] Commander Jared ISAC now emerging watching from the no up down left and right are three pitch and roller three Y in two switching single-handed operations are fine static and with Dynamic disturbance glitching for left hand up down left and right are threes maybe a two ditch is a four roll is a two Y is a two so these are the suit Mobility checks that Jared operations Dynamic and which disturbance are all adequate one complete HJ 5.3 PSI 48% RH 33m 9 C SpaceX copies test Matrix one and HUD readout e stepping into vertical translation we're going to start with the bars all right we're going to transition over to vertical I say vertical and horizontal are equally workable slightly Savor horizontal I'm going to do a Max reach left hands at the top of the mobility Aid at the mid point you have video we just lost our live video stand by one okay Switching over to Max reach switching I'm holding up at the max reach And1 go ahead and continue the operation uh we'll let you know we're back on

the handsfree demonstration is very comparable to the trainer in terms of the foot restraints space copies and ev1 when you have time if you'd like to return to the reach demonstration uh we'll take a look at that with the live video test Matrix 3 is complete the Hut read out is 5.3 PSI 47% R 33 deal 8 C and stepping back into max reach copy test Matrix see top of the mobility a and uh let's get a

any go back negative we got about 1 minute until ed1 Ingress happy to have one minute it's gorgeous E1 we're checking out your helmet cam now well I'm checking out your nose going right now and looks pretty good cop we're turning those cone see you looking at us all right we're coming up about that 02 timer time check for E all right than T1 that's for the huge steam effort that it took to get us to this point you know it's just to start then I'm transitioning back in your vehicle there's space at ev1 just taking a quick look here into Hatch wheels from what I can see so far they look pretty good copy on the hatch seals and standby for transition to read off reset finish this and ev1 is clear all right so Jared back inside uh we we heard him going through What's called the test Matrix uh it's basically just a bunch of maneuvers using different hands using the foot Mobility calling out numbers right now though we're doing you just heard Arthur call up three off reset so we didn't use any of the forward thrusters while Jared was out there we're re-enabling them putting us back in our perfect attitude before Sarah gets ready to go out the door fun thing to note it's still not a perfect vacuum inside a dragon is it's an open loop system so oxygen is kind of getting dumped into the cabin as this is going on so you got a higher pressure in Dragon than you have outside so we're not worried about Thruster pluming yeah now you mentioned Sarah um just like Jared she will have 10 to 15 minutes uh outside perform those same sets of Mobility tests as Jared uh like we heard the core do um with ev1 uh they will call out when there's one minute remaining uh attitude reset complete ev2 go for erress there is Sarah's clear to proceed crew check for E e1's Good's good good EV is going to go stand on the door and then step [Music] outside now this test Matrix that uh Jared just performed and the one that Sarah's about to perform they have both committed to memory um in order to execute these um we saw it being done pretty efficiently I can't believe how quickly that time went by Mike we were talking about how your Spice Box were hours and these guys only have 10 to 15 minutes and it just like that yeah it it can go pretty quick and uh but fortunately um look good I see a little bit of a bulge between 14 and 13 so you're hearing Sarah call out some more of the seal check there as as she's exiting out seated SpaceX copies that report good fix so this was something we knew might happen um and S between 28 and 27 copy the crew trained on exactly what to do in the scenario just pop it back in rece it final between 19 and 18 that might be fated with hatch closure SpaceX copies can you repeat the locationa complete between 19 and 18 all right copy I'll track that and uh ask again when you're Ingress copy P2 is theing with e super exciting to see this our fellow space xer yeah Sarah Gillis now about to make her Space Walk e one I'm going to hand this back to you like we mentioned Sarah will be performing the same uh set of Mobility tests uh so we will do the same uh try to stand by and listen to those coms I mean I said it before a lot of the sare characters we want to do this all right stepping into T Matrix one for singlehanded Mobility really cool to see one of our own out there that's awesome and ev2 for awareness we're watching from the nose G and cofy all I would say in all three translation axis I'm having certainly Cross cou of movements forward back I am inducing the F ever roll similarly with left right and up down a bit of a kick but all our capable rating is three n for three R is a four and K is a three from Left Hand stepping into vertical [Music] translation copies and ev2 for awareness we're tracking an Ingress time at O2 flow 59 minutes happy 59 minutes horizontal bars are definitely preferred and I not be able to stabilize my body with single hand disturbances C for breath left and right stepping into max reach

5.25 33.8 Celsius 37% humidity Space X copies H readout and test makers one [Music] 72 like we mentioned before views going in and out doing during due to those ground station uh coverage gaps yeah we we coms are the same coms are through satellites but we've got ground stations for video on dragon as you can see in tracker we just flew over on New Zealand we're about to go right over the middle of the Pacific no ground stations in the middle of the Pacific are actually pretty good we're hearing the voice of mission specialist Sarah Gillis our fellow space xer on her Space Walk got got about a minute left and then she's going to start heading inside and a little more work I can actually get between almost bar one and bar on C and you could see the Earth dark and we flew into like an orbit am test makes to kind of combine them so we'll call that conce pressure 5.27 38% humidity 33.7 celd SpaceX copies Matrix complete and H [Music] outo I'm able to engage and disengage my feet happy night of you to and once you are able to engage disengage we'll actually have you start Ingress we're just over 5 9 Minutes O2 flow cyress Che for good good coming down in all right and just like that Sarah's going to start making her way in check those hatch seals again SpaceX cop on Striker plates and ev2 I have one more ask for the hatch if you can check that as well when ready to copy copy copy and ev2 what I'll have you do is when you Ingress can you get eyes on the hatch handle mechanism and see if the handle has been stowed in the Do Not Stow uh window and rep if you can see that Jack I think it's just outside copy just outside thank you just outside the range and for awareness I do see a couple of the same points buing again between 12 and 13 copy your go no mostly between 12 and 13 right now SpaceX copies at 12 if you can you're go to address those cop these numbers being called out represent the location around yeah the location around the circular hatch just identifying where these bulges are so Sarah is now reating that seal not quite able to reach the bom so we'll proceed with clearing for hatch closure just like that we're already hearing about hatch closure it's incredible that these two Evas just in two blinks of the eyes are uh DC is clear please on your screen there is SpaceX core uh or crew operations and resource engineer on duty tonight is Arthur baralt this is the uh the voice to the crew throughout uh their operations of course you know everyone has to sleep so we have different shifts for core um but Mike your time and dragon good Cy a f for and closing once we get ground station coverage uh again we will be sure to bring you views within the Dragon capsule but right now Sarah is closing the forward hatch it sounds like we might give the motor a try [Music] IND Eva hatch closed Alles enabled Dragon SpaceX we see Eva hatch closed and pressure indicates good hatch seal standby for transition to Eva repress one and E one copy secondary O2 BS Clos then support one I'm TV1 [Music] Clos a couple of real big moments right there Sarah was able to make sure the copy secondary flow is closed and agree EV press one he was able to make sure that the seals were in good spot we got the hatch closed you can see for 83 see the pressure starting to tick up just a final confirmation everyone confirmed secondary O2 Val are Clos gas and we're one for all right so each of the crew just closed those secondary O2 valves on their umbilicals again that was primarily for cooling um during the space walk itself suit still pressurized by that primary and now we're going to start to see uh the pressure tick up inside of dragon right after they get the hatch closed they're able to do kind of an initial pressure check CU again oxygen it's an open loop system with these suits still flowing into the cabin you're able to see positive pressure response showing that the cabin uh the hatch was closed and was sealed uh we'll still do a leak check on our way kind of back up to our nominal cabin pressure um so we're going to continue ticking up until we're about 8.3 PSI and then we're going to transition into the second phase of our repress um really the difference between repress one repress 2 is how frequently we're injecting atmosphere uh as kind of the the repress is also pretty unique with dragon um where repressurizing with just nitrogen right now um which is a little bit unique obviously you have nitrogen and oxygen in your atmosphere uh with this we have O2 flowing into the cabin through the suits so we only need to add nitrogen so we're able to just basically add a bunch of that to really start getting your pressure up O2 continues to flow into the cabin through the suits and we're going to continue pressurizing until we're pretty much right back at our 14 right about our 14 uh or so PSI and we're also looking at what the partial pressure of oxygen is cuz we want to make sure who takes helmets off and everything that plenty of oxygen in the cabin and then we're going to change that injection rate to just help with the mixing is micro gravity everything's harder everything's on hard mode um and you don't just have natural convection so like I mean space station I think I've heard it a bunch of times Mike like you just constant noise of fans that's right yeah there's uh you've got to continually recycle that air um and one to help get rid of the CO2 right because as they're taking in that auction they're breathing out the CO2 and we need to to get that out of the system which is another important reason to have that air constantly circulating yeah um man that felt really quick that was it did that was that was that was really cool to to see them outside for the first time and there they were what they were actually doing out there is a bunch of pretty simple tests as it looked but like this is just learning how the heck do you move cuz like just moving around yeah in micro gravity is tough right it it is tough two Andes from hand out of three yeah that that movement is tough and and there is a big difference just of moving around when you're in your short sleeves like we're in inside the capsule and when you put on that space suit uh it it's much more challenging to to move around with that on yeah and what they were really doing was just kind of like you put your hand on on Skywalker and then you're changing your pitch you're doing translation up and down and everything and then the one that I think is kind of cool is Max reach cuz like just going like that is you know not easy yeah and I think one of the other things I thought was interesting is you heard I think it was Sarah talk about the horizontal rail versus the vertical and how much easier that was for her to grab onto or utilize versus the vertical one so simple things like that you know for us it not a big deal uh but out there in in that uh in the vacuum and in the microgravity environment it does become a a much bigger deal and you and you know Dan and I we've never been in space so we certainly appreciate all of your expertise that you've be able to share with us throughout this morning's operations and uh contributing your two cents yeah no thank you it was great to be here uh just an incredible moment uh not only for the Polaris Dawn for all of SpaceX and really for for Humanity because it's just one of those small steps that's taken us that much closer to being that interplanetary species so thank you very much for having me around our pleasure you're welcome back anytime excellent all right see ho thanks all right so repress is continuing we're a little over 4 PSI right now again we're going to keep that going up until we're a little over eight and then we're going to change our repress rate uh we're basically just going to be injecting nitrogen for shorter periods of time that's just going to help that atmosphere mix as we get the crew kind of back up to their basically their normal cabin atmosphere that they were they haven't actually been at for the last couple of days cuz we we started this whole right after we got yeah it was almost like we we launched them and gave them two seconds to acclimate and enjoy their cute zero g indicator and immediately stepped into the pre-bath um in order to prepare for today's activity uh and really like you said let them acclimate and uh let their bodies adjust and you know the success of that really was demonstrated today by the fact that we were able to step through uh all of the steps today without having to take the uh and available breaks to allow the crew members to adjust during oh sorry I thought we were going to get something there com the the teer sing out so like we'll get it back but um so yeah just the fact that the uh all four crew members were able to just go right along and didn't have to pause um as the option was available I think it's a testament to the preparation that they did before and during [Music] good just heard a quick check in from them so we're going to keep keep counting the PSI up until we get to about eight we are going to do another leak check on the way up uh to our nominal cabin pressure uh as you introduce atmosphere you're introducing temperature changes not just pressure changes and so we'll essentially we'll get to a nice pretty stable point when we're at eight and then we'll let let it hang out there for a couple of minutes uh Let The Thermals kind of cancel out um that'll take about 5 minutes to do that uh this obviously has to be done to make sure we've got a really tight seal with that hatch as before we let crew get out of their seats move about the cabin anything like that want to make sure dragon is fully recovered this is we B we just use dragon as an airlock yeah and actually the info that you were talking about you see it there on your screen live with that telemetry there in the bottom left and bottom right hand Corners um we can see the Dragon capsule and the suit pressure starting or not starting But continuing to to Rise um it is incredible that we've only been in the Eva for one hour and 13 minutes um it flew by so so quickly um press approaching one PSI on C2 I'm I'm sure for sharid and s it flew by even quicker yeah we just heard Jared call down we're coming up on one PSI for P2 so what we're really tracking before we give the crew the go to get out of their suits is both the actual like just the straight up what the absolute pressure is inside um but also what the partial pressure of oxygen is we want to make sure you you don't have a hypoxic environment inside basically you want to get them they're going to be pretty much right back at the atmosphere that we're walking around in right now uh before they get their suits off uh our Eva clock's going to continue to count until we hear the call for Eva uh operations complete from our core Arthur burial that's going to come uh once we are done with the repress repress operation uh we'll see a couple of uh other things happen with the suits they'll uh do kind of a final wash out of the P2 environment in the suit using Nitro before they get out Nitro being that same air mixture that you have in your scuba tank if got any scuba divers out there uh that nitrogen oxygen mixture um nope still still just there they're just going to keep ping should hopefully be getting video back from ground stations s and by for transition toess two F along at yeah so once we train transition to repress 2 once we're at about 8.3 PSI will stay there for about 2 minutes and then once the cabin gets up to 9 we're going to pause the repress and we're going to do a cabin leak check this is another kind of critical check we did the initial one after they closed the hatch where you're able to do just kind of a let's look at the pressure is it increasing at the rate we expect inside Dragon yes it is um and so we were able to confirm that seals and everything looked good we're going to do another leak check now that we've got more pressure inside Dragon just to really make sure that we've got a good seal on that hatch before we finish the operation coming up on 8.3 we should be hopefully just about a minute and a half or so away from Brown station so might get those views back inside a dragon I yeah it would be it would be great to see them uh post Eva now just like when we were depressurizing the capsule there were there was the option to uh pause and yeah that CS it we're hearing continual checks with all four crew members to make sure that everyone is good um if the answer to one of those those checks was no there would be an option in this repress sequence to uh pause possibly to reduce the um you know allow for ear pressure Equalization um but again just like the way that we depressurize now this repress it seems to be going uh really smoothly yeah we're just about at 9: I'm going to say we're almost there and then it's going to tick up we're going to pause at 9: we're going to do another cabin leak check so we should hear that momentarily evess two stop with you and evess to stop 5 minutes for theral stabilization than we tracking and improve for your awareness we positive refr here 30 seconds in theck like we mentioned earlier uh right now the this repress is being done with nitrogen um once we get aess cp2 is 3 halfway there they're still flowing that oxygen um and in a few minutes we will begin to flow we'll do a flush uh of of nitro uh into the suits all right we got our views back there they are it's a little sad to see that forward hatch closed again it's it's got to be really hard when they tell you it's time to go back in yeah just one more minute y reminds me of when I was kid swimming in the pool you know time to get out just one more minute you it it it speaks to to the professionalism for for Jared for Sarah for the whole crew really like that's that's got to be this is something they've been training for for years and it's got to be really hard not to go for those you know that extra 30 seconds but they're true professionals yep they know there's a timeline [Music] che2 just pass 1.5 we're a couple minutes into our leak check you're you're seeing the pressure continue to tick up we've stopped the nitrogen injections but again oxygen coming out of potentially vent line on those suits um and that that is why you're going to continue to see the pressure tick up you heard Jared call out the P2 that's gone up that's your partial pressure of oxygen uh we're looking to for that to get to over about 2.6 a little bit higher um and then our final actual like just ambient pressure inside dragon is going to be right around 14.4 or so and I mean that's that's a little bit lower than what we're walking around it now but like if you're at a little higher altitude uh state in the country or something that's that's what you might be sitting in right now in your house and that's they haven't been at that pressure since they left her yeah uh but after we get all the way up there we're going to do kind of a final uh flush of the suits using that nitrox the K was talking about uh that takes them out of that pure oxygen environment and that's one of the final steps before we'll he hear that call from Arthur vva operations complete and that's when our clock's going to stop uh or Space Walk did start today at 3:12 a.m. Pacific 1012 UTC continuing to tick up ours was unique we we talked about it a little bit with Mike there's there's different rules for every single Space Walk it's it's kind of it's fun a little challenging sometimes to track all of them um on the even on the space station there's still we're about halfway through the leak check so we got about 4ish minutes left we can see the uh pressure inside Dragon stabilized during the Sleep check at 9.4 helps to ensure that uh that forward hatch is properly sealed and and shut it's very similar to a suit leak check um that we do in terms of sustaining a pressure and measuring that pressure over a period of time um and obviously the the leak check for the capsule takes a little longer than the individual suit leak checks uh but so far so good a little bit more than halfway through bigger volume right so we hit hit essentially a thermal stabilization so again this is the fun I think it's chemistry I'm not sure but like as as you're raising the pressure you're you're changing the thermal environment inside the cabin so temperature goes up your temperature goes up your pressure can go up so you wait for all of that to kind of equalize and once that gets at a steady state you can do a a real no kidding pressure check on this hatch and so we're we're underway with that that's going to take a couple of minutes and then we'll hear the results and then look to resume uh with the repress it'll it'll slow down a little bit um for slow down a little bit for the remain of the repress uh kind of kind of going in reverse when we did the deess that initial a lot of that atmosphere is flowing over um and once we got down low it started to slow enjoying these in Cabin views everyone good we're going to wait to P track sometimes it seems as though the the feed freezes just because everybody's relaxing as [Music] the is n decimal 7 pp2 is at [Applause] two the final final minute of our leak check reports from the ground everything's still looking good or Jared report down that partial pressure of oxygen right at about two once that gets to about 2.6 we can essentially stock flow of that pure oxygen to the Cru suits is like 2.6 is right where we want to keep it when we're at our final pressure Dr successful standby great news there successful Lea check of the cabin all right crew we're in EV repress 2 as a reminder Eva repress 2 will complete when either pp2 reaches is two decimal 62 or cabin reaches one atmosphere right now we're coming up on 10 psi per cab pressure and C2 is two decimal 2 it's a really good explainer there from Jared again those are those are the values we're looking at we're seeing uh the P2 that partial pressure of oxygen continue to tick up once that gets to about 2.62 uh we're going to be done flowing that pure oxygen to the suits of the crew uh and then eventually we're going to get to one atmosphere it's about 14.4 as our Target for today uh and then our refresh will be complete so uh this will go a little bit slower than the initial refres uh this could take uh up to about 20 or 30 minutes even in some of the times that we simmed it uh you don't want to introduce them super quickly to a higher pressure um anytime you're doing pressure changes as gradual as you can make it the better um and that's why we have like the built-in holds that we talked about that the crew can do exactly uh these are opportunities for the crew to pause the repress and just um allow themselves to equil to come to equilibri equilibrium words words are really hard right now um and uh we haven't had to utilize 2.3 P2 targeting 2.62 cab pressure is at 10.3 I was a betting man I'd say we get to the P2 threshold first at that time U will switch to nitrox in the all right good news there Dragon we with e continuing to repress the cabin we had a successful leak check uh and you can follow along with uh the repress uh along with the data there at the bottom of your screen um as Jared said we are targeting uh 14 about 14 psia for uh cabin pressure uh or when cabin pp2 that partial pressure for O2 reaches uh about 2.6 so we are continuing to progress uh pretty well 7.5 however as Dan just said this this portion of the ress could take up to 30 minutes uh just so that we're allowing the the crew to uh acclimate along with the capsule really cool day so far it was awesome to see them you know out there going through the test Matrix like we we only got to talk about it a little bit but you know just some of the the different test that they were doing while they're out there this is like fundamental how do you do a space walk well first of all you use your hands a lot and how are you going to be able to move around this the first time we've ever had the suit in that environment crew and so they were they had a basically a checklist of like these are the things you're going to do it was you know use one hand and wave the other other one around and see how well you can stabilize yourself and and and then rate that activity on a scale of one to five and report it back to we we could hear that a little bit in in the activity of okay I'm doing this thing here's how here's here's the functionality of that test yep yeah and then doing doing the reach test doing the up and down and uh they did it at the very end you saw Jared go handsfree for a second and that was he that we had a foot restraint uh in Skywalkers well if you've ever watched a a space walk in the space station you've seen astronauts in the robotic arm getting flown around with just their feet strapped in that's a pretty critical tool when you're working in micro gravity because otherwise you know you go to you go to swing the hammer and like it swings back at you so you need something to kind of brace yourself and a foot restraint can be really important yeah it was uh we also saw um the helmet cam getting checked out uh that was uh certainly a highlight for us to see what Jared was seeing uh even though at that point I think we were in uh you know the orbital night but um it it was many amazing views and it went by so quickly uh both Jared and oh we got views again with you remind to start manual timer on night got we standing by there it is started on N purs T2 is two decimal and cabin atmosphere is 11 one de well it might look like the feed is frozen if you look closely you can see small micro movements there with fingers and uh the strap above Anna's shoulder um we uh unfortunately due to uh ground station coverage don't have video 100% of the time even though we wish we did that would be great but we can see that uh Jared and Sarah uh are not strapped into their seats of course because they performed uh their Evas or their space walks uh extra vehicular activities where Anna and kid remained in their seats the window seats so we can see their um safety harnesses uh still strapped in there um at this point in time we are continuing with the repressurization of the uh of the Dragon capsule Dragon resilience uh we had a successful leak check good Commander Jared isaacman continuing to check in with his three fellow second2 valve open ev1's open e2's open one yeah one open two open continuing to repressurize the Dragon capsule we're targeting about 14.1 psia for uh the dragon pressure which is the uh Telemetry readout in the far bottom left corner of your screen yep and along with that we're also tracking the part partial pressure of oxygen so we did hear that they've stopped the flow of P2 to the suits and they've switched over to nitrox so again anything that we're flowing into the suits also gets introduced into the cabin atmosphere it's an open loop system it's how you essentially maintain pressure in the suit um since you're just constantly flowing that air in there uh to wash out any carbon dioxide they're exhaling to actually function as they're cooling um so we're switching over to nitrox just to make make sure we we maintain kind of the right balance of nitrogen and oxygen in that cabin before they get to go to take their suits off so we're already at that um for the O2 and so we're we're on nitrox in the suits now still injecting um kind of the pure nitrogen into the cabin itself and the teams just keep an eye on the O2 levels as we go throughout and we can we can adjust our injections as we need to uh so we're we're just kind of hang out now waiting until they they get to that uh that 14 um a little yeah a little over 14 and then uh the the call we're going to be listening for uh is going to be Eva operations complete um from Arthur four four minutes into the C P2 is 2 deal 9 C pressure 12 deal 5 you can see the Polaris Dawn crew continuing uh as we continuing to monitor uh the repress of the Dragon capsule on the far left side of your screen is Mission specialist and medical officer Anna Menan to her left or our right is Mission specialist Sarah Gillis uh both of these wonderful women are our fellow SpaceX employees so incredible to see them in space doing amazing things and see see and Sarah gets a poke her head outside dragon that was I mean both of them have trained astronauts they've basically gotten people ready to go do this and it's it's got to just be really special to get up there and do it themselves incredibly uh and then to the right of uh Sarah was commander Jared isaacman uh who was the uh first who performed the first Eevee um operation or excuse me Eva operation so Jared went first and then uh Sarah after him and then on the far right hand side of the capsule uh so not this photo but the the live view inside um was uh Scott potit prefers to go by his call sign kid uh he had the other window seat um now if you tuned into the launch phase of Polaris Dawn uh you might recall that Scott pressure 13 3 Scott is actually our polaron pilot so in order to enable Eva operations he and Sarah had to swap seats so Sarah has been keeping uh the pilot seat warm for kid yeah like we talked about only say only we only saw Jared and Sarah actually get up and go outside but all four of these crew members did a space walk today all four were exposed to the vacuum of space this is the first time that's ever happened in human history having four people all at the same time yep we saw Jared and Sarah go out and do those Mobility tests uh Anna and kid uh they're one of their kind of main roles was being the eyes back inside very similar if you've ever watched the space station and Space Walk where you'll have people inside who are able to kind of call out or fly a robotic arm or something they're just a really important part of the team to make all of this work like no space walk doesn't happen in a vacuum it happens in a vacuum but like you're never doing it solo um and so they were they were largely uh making sure that umbilicals didn't get uh hung up and keep an eyes on seals and stuff like that for the crew um so also keeping an eye on the umbilicals in case if it got wrapped around their foot uh and just really acting as the uh assistant coach uh while while the Evas were underway right where coming up on 14 PSI again we're we're already at the the oxygen levels in the cabin that we' looked for and so now we're just waiting until we get to that that final pressure technically the Eva is still underway that's right uh we have not yet heard the call out Eva complete uh that will be uh that will be coming after we get a confirmation that the repress 9 minutes into the O2 wash out less than 4 minutes remaining cabin pp2 is 3 decimal 1 cabin pressure is coming up on one on 14 decimal 1 we want to do a few things so when the timer reaches 13 minutes we're going to uh shut down the nitrox FL the suits then we're going to close secondary O2 valves and then you can vent uh use your manual vent valve in the place when visors do not disconnect themop Happ one good good Dragon Space X we are less than two minutes from a teer Handover but copy your call and plan we can that was Jared just uh reminding the rest of the crew um that their uh when the timer hits 13 minutes um the order of operations they they have that manual valve there uh and this is something that we've seen all morning is continual checkin suit great news there confirmation that Dragon repress is now complete so right now we're just waiting for that final we call it the O2 wash out so again we've been using nitrox instead of the the pure oxygen into those suits for anyone that has joined recently unfortunately you missed most of the fun encourage you to rewind yeah go back about an hour um we have had successful completion of both Jared and Sarah's space walks we saw them uh move through their test Matrix and perform the suit Mobility tests and the uh the the testing of the Skywalker uh Mobility Aid at located at the top of the Dragon capsule they move through it quite quickly really quite in the blink of an eye um and we've closed the forward hatch we have repressurized uh the Dragon capsule and uh we're now standing by for really the the the final operations of the morning um so yeah unfortunately if you only recently tuned in you should definitely rewind and and go back there were some incredible views uh of the taking place during the Evas uh the crowd that we had in front of Mission Control here in Hawthorne uh was almost on Q uh we certainly excited as were we to see the the views of Jared and Sarah emerging from the top of dragon resilience uh it's been quite a morning and can't believe it's already almost 5:00 a.m. Pacific uh we had it is arming disconnecting and yep all right check secondary O2 valves closed ev1's [Music] closed give Clos 4 One Clos 4 two Clos all right you're going to manually event down [Applause] as we near to the end of the webcast because we are just left about to have that final call for the Eva to complete technically still we are in the Eva so finally flying higher than any previous dragon mission to date and reaching the highest orbit ever flown while moving through portion of the Van Allen radiation belt at an orbital altitude of 1,400 km from Earth surface or more than three times higher than the International Space Station this was the highest altitude of any human space flight mission in more than half a century since the Apple program and we got the final call edva is now complete also with today's Eva Sarah and Isaac man in an altitude of 700 km seized several records three times higher than the ISS it was the highest Eva ever in Earth orbit smashing an altitude record of 1,370 kilom set by Gemini 11 astronaut Charles conard and Richard Gordon back in September 1966 also Sarah became the youngest human to space walk eclipsing first ever space walker Soviet Cosmonaut Alexi leonov and jointly with Menan and gillin Gillis they flew the highest altitude ever attended by a woman which they made it to make it more than double the 576 km reached by astronauts Kathy Thorton Nancy cury and Megan McArthur across three Hubble Space Telescope repair flights between 1993 and 2009 this task before he ingressed got back inside a dragon uh we did that quick attitude adjustment and then it was uh SpaceX his own Sarah Gillis second to exit the spacecraft do her task for the uh for the Eva uh Jared and Sarah got back inside everybody's reporting back healthy we had a pretty smooth and nominal repress uh our mission pilot Scott kid potit and our mission specialist and medical officer Anna Manon have been supporting the space Park throughout now upcoming tomorrow the flight day four the Polaris joh crew will be testing laser based satellite communication using the optical inter satellite links between Dragon spacecraft and staring satellite hopefully we will be getting a live stream even if not please keep in track on our X handle so that you will be knowing any updates from them everything on their suit um these were only needed obviously while they were in there they're going to be able to get out of their suits uh next and kind of start moving around the cabin they turn the Vox off so we're not hearing kind of like the constant back and forth anymore um but wow really cool to see him back inside he complete and it's uh you know the the work isn't completely done yet he'll also have to perform some comms checks uh along with some additional tax tasks before uh their seats are rot ated back into their preeva position uh and all in all it's wow just an incredible view we've said it already a couple times before if you're just joining Dragon SpaceX will be with you when you're ready in 9 decimal 3 cabin atmosphere is looking pretty good right now very stable and following flight day4 on the flight day five will will be the final full day on Orbit on that day crew will be wrapping up all the research that they will be performing webbed in every single day of the mission and following that we will be arriving the flight day six so in that day having space suits Dawn the polar is Dawn crew will re-enter through Earth's atmosphere and then splash down off the coast of Florida at one of the SpaceX 7 sites and will be recovered by SpaceX recovery vessel either by Shannon or Megan so I guess it's time for us to wrap up the stream on is the first mission in the Polaris program that will demonstrate new technologies conduct extensive research uh and ultimately culminate in a flight of space axis Starship with humans on board all of this while continuing to raise funds and awareness for important causes here on Earth now you can learn more about the program at Polaris program.com this has been an incredible mission on day two dragon went to its high apy point the highest point in its orbit more than 1,400 km that's higher than any dragon mission to date this is the farthest from Earth anybody has been since Apollo and been 50 over 50 years since 1972 and then today the crew first civilians to perform an Eva in space first one in Dragon yeah and the crew also uh the first to test starlink laser-based Communications in space uh excuse me I got too excited and of course we'll also be back to bring you live coverage of Splashdown uh which uh we are hoping to have in a couple of days obviously weather dependent um but you can stay on top of all of the SpaceX updates by following us on X thank you for watching and we'll see you back here real soon so with that we will wrap up our coverage for now it seems like we won't be having any live coverage for the testing of the star links as per Kate but maybe we will have some videos there on X be sure to check out our social media handle on X for the latest happening in space industry and updates on upcoming launches hope you enjoyed the stream we appreciate everyone joining us for today's historic extra vehicular activity of the Polaris Dawn Mission wishing everyone a great week ahead thanks for watching this is asri Del live and me dpto signing off for now and we will see you next time B [Music] [Music]
