Watch again: SpaceX conducts first private spacewalk with billionaire on Polaris Dawn mission

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 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 Pary raise and lower 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 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 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-and 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 Starling 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 adap adapter can be swapped out drag and you guys are welcome back aboard if you want SpaceX 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 got it 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 um 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 koua 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 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 we went over it you literally called Dragon home during that time what was it 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 and it was a 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'd call my family every night before I'd go to bed and I'd be looking out the window uh at the Earth uh as as I was doing that it was uh very special did did any of them get jealous because 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 4 launch but it wasn't a very long time and yet you were able to take that docking adapter off put the uh Koopa on in a in a very short time which is also pretty impressive I actually have that noted here uh crew one took off in November of 2020 and inspiration for 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 impressive your mission patch sticker is in the is in the capsule that they're in now and add their own sticker too as well right 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 our that we give to NASA astronauts they also had to train to perform their Eva though for basic training at SpaceX Hawthorne they train 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 [Music] 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 manufacturers are 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 activity 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 it 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 of dragon to get outside and do The Space Walk we had to add in new joints um a new features in the suit to allow them enhance Mobility while the suit is pressurized when a crew member is pressurized 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 uh 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 inseam uh but since we needed to have lots of Mobility on our Eva suit that was not the Preferred Choice by moving the Zer system from them inseam 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 this build 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 uh which we referred to as the Faraday layer and this is a conductive cage around the suit that Shields the suit from external electric [Music] Fields the helmet on the Eva suit uh looks very similar to the Iva suit but is really an all new design of that helmet um it's much more robust from a thermal structural perspective since it would be taking more extreme temperatures we are really excited to introduce this new single pane visor helmet to the world of space 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 cud 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 [Applause] [Music] day we also had a chance to talk to the SpaceX team that developed some of the hardware and procedures for our first Space Walk let's hear what they had to say Eva stands for extravehicular 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 on we're going to be testing the mobility of the suit we're going to see if the inp space 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 walk on earth in a way that's represented 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 in to 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 play ston 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 the single crew member inside the capsule we can lift them up and get them situated so that they can egress 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 really really amazing Mobility dat 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 sideway suspension system so gravity isn't helping them close or helping them open that hatch mechanism it's new development for Dragon it's 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 polaron objectives are the first step towards that ultimate flight with with humans inside of Starship which is right along the SpaceX development path 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 hotpots 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 and Mar oh they 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 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 suits 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 feels good what doesn't um 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 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 spacewalk as opposed to say your feet when you're you know cuz 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 uh what's called delamination on my fingernails um 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 leak 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 LE check what do you do next and and so there's always usually procedures associated with that as well that 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 leak 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 spacewalk they're all going to be exposed to the vacuum of space but I mean even when you did space walks it's 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 hard 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 stand 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 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 space walk 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 shagon um ev1 is completing glove zipper closures but at this time we are ready for seat rotation copy that for SE rotation can you confirm crew is ready with the current glove zip 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 standby well get them to the 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 uh that one all the way in the bottom left corner that's your dragon that's your dragon cabin pressure that's in PSI space you're 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 the seat rotation we'll 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 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 SE rotations complete so now they're going to start doing that tear getting [Music] ready Cy and can I get a confirmation of completion per the call out in two decimal 18 want that's complete with 2.1 copy at this time you are go to step into section three and tear suit [Music] deers 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 Space Walk operation is ev1 um Sarah's call sign will be ev2 Anna will be support two and uh Scott will be support one uh also Scott and Sarah are switching seats uh I may perhaps they already have copy standby for HUD power for pressure sensor checkouts 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' 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 the center seats then you'll have Anna and kid on either side Dragon SpaceX suit Huds powered report results of primary sensor HUD checks in three decimal to 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 that's always kind of felt like that's that Space Age Technology that we're missing cuz 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 it's uh of course the the suits and head checkouts complete nominal copy swapping the backup sensors standby 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 our first live views inside Dragon resilience for this morning that's fantastic yeah I think this is the definition of chilling yeah so 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 Hut checks the crew is going to check out those heads up displays one more time real quick check out back C copy good Huds returning to stand by for helmet camera check outs uh 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 has 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 uh they'll be able to see their sup 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 em 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 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 out of yeah all right um so they're 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 um 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 good and almost double check your work copy check out's complete Huds will remain powered proceed to step 3 decimal c 3 operations review through 3 decimal 8 report when 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 like 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 Space X repeating checkouts are complete Huds are going to remain powered proceed to step 3 decimal 3 operations review through 3 decimal 8 and Report when complete happy 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 and 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 try and 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 I 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 spacewalk is to manage those Abal for you guys Mike you had one that's uh what plugs into kind of the leg in your suit and that's what's providing like the breathing connections all of that stuff uh for the spacewalk today it's a little bit different this one uh that uh 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 have so so it's Dual Purpose 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 fft 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 cuz 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 floating basic Dragon Eva offie complete crew are in position for Eva start nice EXC cop crew in position but you saw Sarah kind of move the tether out of the way and the part of that is that's actually impacting X you are go to command box push a talk all seats copy and so this will this will be one of the unique things about the spacewalk 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 vet set go for to check1 to check ev2 com check support one com check support two com check SpaceX copies all good coms all four crew [Music] 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 suits um how how loud does it get inside your suit it it actually is quite loud uh that air flow is just constantly which 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 initiation 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 sup 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 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] spacewalk verify your visors are closed secondary L2 valve is open and that you are go for the EVS ev1 is go ev2 is go support one is go support two is go Dragon SpaceX initiating secondary [Music] O2 and with that news our Eva has begun so you're you're going to hear referred to as primary and secondary O2 primary is going to be that primary flow of oxygen to pressurize 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 their 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 then 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 like no that would be pretty that' 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 STK contrast as soon as we get uh the Eva or with the hatch open and ev1 out there yeah it's 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 day 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 at the Sun Dragon SpaceX a reminder after the initiation of primary O2 flow ev1 ev2 will need to adjust Vox threshold low following primary O2 flow [Music] initiation B one copies BB2 copies Dragon SpaceX secondary flow Purge complete close secondary O2 Valves and Report ready for suit [Music] pressurization ev1 closed ev2 closed P one Clos CL report two closed BX 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 their 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 Le 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 1/2 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 after we get through the Le 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 St complete second on repete ev1 open one open the sh open and right there they they finished the purge and they did a quick uh reinitiation of that secondary flow check response secondary flow and Report went complete give one close support your close L you [Music] close support one stay confirm secondary CL [Music] 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 [Music] [Music] earlier support one SpaceX Conta [Music] [Music] we got you we got you all right copy got the one [Music] Dragon Space X beginning to the check evaluation and then still for the [Music] checks so 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- 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 nit out um and we started pre-bed just two two hours after they got on orbit just by you know gradually lowering the pressure and I mean pre 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 free breathe um that's how we used to do it and it's very similar to what what the Polaris daon 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 6 hours prior to going out the door uh but it's not 2 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 Dawn 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 right 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 station space walks I'm still really upset I never got in the pool that looks like one of the coolest like parts of being an astronaut is like not being in space but just doing some of this training yeah Dan I I I tell you I can still remember the first time I stuck my head underwater 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'll be back on board with cameras in 3 [Applause] minutes so our core just called up we'll get we'll get views back 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-bed still we started our space walk about 133 minutes ago when we initiated O2 flow to the suits that time is 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 to 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 C events so you know what's what's going through your head when you're like man it's happening the Air's going out it's really happening it's happening yeah I 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 breath 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 follow- Dragon um but yeah just as a reminder uh our our crew they are in their 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 3 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 include 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 uh kid and uh Anna will also be performing an Eva in their own right that's right 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 we terminate or abort that The Space Walk during that venting we cannot start again we talked a little bit earlier about how consumables are like thing that really drives you uh and for us we don't have a great big airlock with this with you know a full station worth of oxygen and stuff like that um [Applause] [Music] so T1 [Music] go copy initiating cabin venting there we go that is great news exciting so uh that breathing of incre that 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 6 in total this will take about 8 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 sup 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 four .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 or and Dan and you talked about that about five PSIs what 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 C from the crew they're they're monitoring along1 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 Deep pressurization 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've 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 any of the kind of the stion 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 four PSI two pressures look good copy four so Jared really can't open the hatch all in one fluid 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 had 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 devic 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 stressing 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 this 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 or it's going to get real hard real quick right that's right yep uh we did we did also hear uh dragons moving into its uh its 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 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 an ev1 cont check ev1 moud and clear moud 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 Vox 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 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 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's good two yeah you really have four Mini Spa or spaceships in there press approaching PSI guess that means we have four aliens in there too yeah that's right Dragon SpaceX less than one 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 in Chen [Music] prep one copy yeah I think you heard that the the tedris 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 yeah as 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 air lock 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 stion and then we're going to be able to uh 1.5 csia all suits look good one cop 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 space walk today which again that started when we started flowing O2 to the suits of these crew members that was at 312 Pacific 1012 UTC we just heard that dragon's now in its Eva attitude hand over [Music] complete so again we've got we've got dragon's trunk pointing towards the sun you on board watching through the cross [Music] view that was SpaceX core Arthur baralt 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 inter 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 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 satellites uh once the hatch is open we're going to disable any of the Draco thrusters that point forward cuz you don't want thrusters firing off members outside we're at one you can see the S pressure is ticked down too there's about 4.7 difference between the suit uh 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 cab 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 yes yeah when you when you go out as uh open FR Dragon Space X or hatch open prep andir CR to open [Music] hatch that is greatness you can one we're ready to open hat SpaceX copies Dragon you or go to open hatch excited SpaceX go to open the hatch Mike as you mentioned before that continuous communication [Music] hand 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 uh1 hatches Vis indicated open SpaceX copies standby [Music] should see him give that hatch a pretty strong jolt to release that stion hatch is now unlatched Mike talked about you see him getting his feet getting his feet set that's right danard ask if I got open in the hatch so when you go out a ev1 just like Jared here a ev1 that's that's typically the role for for you is to open that hatch and you guys have to draw straws fight ever 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 our four polaron crew members um have uh gone through the uh O2 flow and we see Commander Jared um Isaac 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 SpaceX Target pressure [Music] reached SpaceX I'm unting the hatch now Jared now opening Dragon resilience into space 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 [Music] open much more movement there on the forward hatch this supp be prettyy exciting for Jared because that center part of dragon Space X that's a good brace we're going to have you repeat the [Applause] [Music] operation center of the hatch actually has a window the hatch is unseated copy let give it another [Music] call it hatches several in turn right 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 X vent complete ev1 return to [Music] seat then ev1 copy transitioning back under the display so again one of the reasons we had Jared do that was to Dragon SpaceX 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 ev1 you are go for manual hatch [Music] open sounds like we got our first audible of the day as we said that we can open the hatch opening the hatch man 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 wow we'll get the views back real shortly uh and then the the hatch see a hatch open and hopefully we see it yeah hopefully we see a hatch open the hatch is open St Tex copies hatch [Music] open that is fantastic news uh for those that1 I'm looking at the seals initial view looks pretty good I don't see any vation copy on Hatch report yeah that seal that you just heard him 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 of the SpaceX can you command open pullet hat this is going to stall it open there is our first view of the forward hatch wide open to space forward hatch [Music] that's if you just jumped in we are 38 minutes into today's spacewalk and the hatch is open on Dragon first view from a helmet cam looking out Dragon SpaceX we see installed ev1 is go to continue [Music] that structure you see there is for1 I'm transitioning back from under the display SpaceX copies we're with you in your helmet cam 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 a progressing I have a feeling the crowd is about to go wild [Music] stch back at home we all have a lot of work to do but from here birth Ser looks like a perfect [Music] world even one I'm going to step into T Matrix one handed Mobility demonstration Commander Jared isaacman now emerging m one watching from the nose [Music] con up down left and right are [Music] [Applause] [Music] threes pitch and roller three y ENT two switching single-handed operations are fine static and with

true check for ingr ev1's good E's good two good all right stay back TV1 GRS for the huge steam effort that have took to get us to this point we know it's just to start then I'm transitioning back in the vehicle [Music] and Space X ev1 we taking a quick look here at the Hat fields from what I can see so far they look pretty good copy on the hatch seals and standby for transition to read off [Music] reset got guys face this and ev1 is clear [Music] [Music] 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 fre off reset is in progress calling out numbers right now though we're doing you just heard copy 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 yes 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 SpaceX attitude reset complete ev2 go for [Music] erress there is Sarah's clear to proceed crew check for ev2 E e1's good EV good good two good EV is going to go stand in the door and then step 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 for hours 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 feels 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 three SE SpaceX copies that report good fck so this was something we knew might happen um and between 28 and 27 copy the crew trained on exactly what to do in the scenario just pop it back in one final between 19 and 18 [Music] [Music] that might be best repeated with hatch closure SpaceX copies can you repeat the location Eva [Music] complete between 19 and 18 all right copy I'll track that and uh ask again when you're Ingress [Music] 82 is the shoting with e super exciting to see this our fellow space xer yeah Sarah Gillis now about to make her space walk you 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 Cals I mean I said it before a lot of us sare characters we want to do this all right stepping into test 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 con [Music] and cofy all I just say in all three translation office I'm having certainly cross Cupic movements forward back I am inducing a bit room similarly with left right and up down a bit of a pitch but all are aable rating is three [Music] Y is a three BR is a four and Pitch is a three [Music] [Music] [Music] [Music] than for for left man stepping into vertical [Music] translation St T copies and ev2 for awareness we're tracking an Ingress time at O2 flow 59 [Music] minutes happy 59 minutes horizontal bars are definitely [Music] preferred and I'm not be able to stabilize my body with single hand disturbances two for breath left and right stepping into Mass reach do you have visual a firm we have visual on the nose [Music] cone cppy from bar four to Bar two from top down and similar reach from bar two up to Bar four SpaceX copies reach and test Matrix one complete SE pressure 5.25 33.8 Celsius 37% humidity SpaceX copies HUD readout and test Matrix one [Music] complete 7 to test Matrix 2 like we mentioned before views going in and out during during excuse me due to those ground station uh coverage gaps yeah we we com some of the same coms are through satellites but we've got ground stations for video on dragon as you can see in the 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 actually pretty good we're hearing the voice of mission specialist Sarah Gillis our fellow space xer on her Space Walk got she got about a minute left and then she's going to start heading inside and let see with a little more work I can actually get between almost bar one and bar four on Max reach space has copes and you could see the Earth dark and we flew into like an orbital and is to try to combine them so we'll call that conce se pressure 5.27 38% humidity 33.7 CSUS SpaceX copies Matrix complete and HUD read out stepping into hree demo I'm able to engage and disengage my seat copy that D2 and once you are able to engage disengage we'll actually have you start Ingress we're just over 5 9 Minutes O2 flow Cy with that may just to sitting atress check for Ang good E's good cppy coming on in all right and just like that Sarah's going to start making her way in check those hatch seals again SpaceX copies on Striker plates and ev2 I have one more ask for the hatch if you can uh check that it as well when ready to [Music] copy ready [Music] copy copy and E2 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 report if you can see that check it I think it's just outside copy just outside thank you just outside the range and for awareness I do see a couple of those same points buing again between 12 and 13 copy your go to no mostly between 12 and 13 right now space X copies at 12 uh if you can you're go to address those copy and 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 reing that seal not quite able to reach the bathroom 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 EVC is clear PCH 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 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 driving Clos you're good puppy the play handle a f and forth 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 confirm the hatch is visually indicating closed hatch is verified L hey commanding Eva hatch [Music] closed Eva hatch closed all Dr those is enabl [Music] Dragon SpaceX we see Eva hatch closed and pressure indicates good hatch seal standby for transition to Eva repress [Music] one and E1 copy one check secondary O2 valve closed CPP support one up ev1's closed T is CL one turn two [Applause] CL a couple of real big moments right there Sarah was able to make sure eess one 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 a half PSI for 8.3 see the pressure starting to TI up just a final confirmation everyone confirmed secondary O2 valves are closed T1 close close 4 close 14 close and we're through one for eight point 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 suits still pressurized by that primary and now we're going to start to see uh the pressure tick up inside of dragon uh right after they get the hatch closed they're able to do kind of an initial pressure check cuz 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 1 repress 2 is how frequently we're injecting atmosphere uh as kind of the the repress is also pretty unique with dragon um we're 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 one coming on Med spe right at about our 14 uh or so PSI and we're also looking at what the partial pressure of oxygen is cuz we want want to make sure crew takes helmets off fing 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 almost yeah there's uh you've got to continually recycle that air um and one to help help get rid of the CO2 right because as they're taking in that oxygen 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 because like just moving around yeah in micro gravity is tough right it it is tough Dragon Space X we're about 2 and a half minutes from Ted's [Music] Handover One Cop 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 capu and when you put on that it's challenging 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 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 with Sarah talk about the horizontal rail versus the vertical and how much easier that was for her to grab on to 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'd be able to share with us uh 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 space sex and and really for for Humanity CU it's just one of those small steps that's taking 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 to see you hopp thanks by all right so repress is continuing we're a little over 4 PSI right now again we're 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 process like right after we got on orbit yeah it was almost like we we launched them and gave them two seconds to acclimate and enjoy their their q0g 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 optional uh and available breaks to allow the crew members to adjust during oh sorry I thought we were going to get something there the the tedris in and 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 good just heard a quick check- in from him so we're going to keep keep counting the PSI up until we get to about 8 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 it hang out there for a couple of minutes I'll 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 1 hour and 13 minutes um it flew by so so quickly um on pressure approaching one PSI on T2 I'm I'm sure for shared and Sarah it flew by even quicker yeah we just heard Jared call down we're coming up on one PSI for P2 so what 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 arur 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 pure2 environment in the suit using nitrox before they get out nitrox being that same air mixture that you have in your scuba tank uh if got any scuba divers out there uh that nitrogen oxygen mixture um nope still still just there they're just going to keep pying out should hopefully be getting video back from ground stations passing seven and Viper transition to repress 2 at 8 dimal 3 and copy that SpaceX we're following along ref press two at 8.3 yeah so once we transition to repr
