SpaceX réalise le premier vol spatial privé | euronews 🇫🇷

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 for 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 and uh Anna will also be performing an Eva in their own right that's right and we talked about it earlier first time four 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 at spere 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 uh if we 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 airlock with this with you know a full station worth of oxygen and stuff like that e1's go go out not copy initiating C venting that is great news 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 are yeah in in total this will take 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 Su 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 yeah Dand and you talked about that 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 along1 kid 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 around 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 tug to kind of break the seal break any of the kind of the stion in the hatchet self 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 devices in there we're going to see 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 this for the first time but we're going into those 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 de pressurization 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 vents an ev1 come check ev1 mad and clear mad 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 uh Comm is is just critical we can see Dragon capsule now approaching close to two 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's one good two good yeah you really have four Mini Spa or spaceships in there press approaching 2 PSI guess that means we have four aliens in there too that's right Dragon SpaceX 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 Hatch open prep One Cop 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 com and we're at it's kind of interesting cuz we're at a very critical phase 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 see it well we're seeing that pressure continue to tick down Dragon originally designed to be able to still operate in the 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 it 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 unlash hatch 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 see s 1.5 csia all sus look good you want 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 little under 28 minutes into the uh into the spacewalk today which again that started when we started flowing O2 to the suits of these crew members that was at 3 12 Pacific 1012 UTC we just heard that dragon's now in its Eva attitude hand complete so again we got he's got dragon's trunk pointing towards the sun on board watching through the cross 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 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 [Music] 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 satellites once the hatch is open we're going to disable any of the Draco thrusters that point forward is you don't want thrusters firing off when crew members [Music] outside we're at one you can see the Su 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 [Music] Mike did you get to open the hatch I did you did yes yeah when you when you go out as Eva hatch open Dragon SpaceX Eva hatch open prep confirm Ked to open hatch that [Music] open open SpaceX copies Dragon you are go to open hatch go excited space go to open the hatch Mike as you mentioned before that continuous communication handle 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 hat is visually indicated open space copies stand by should see him give that hatch a pretty strong jolt to release that [Music] stion hatch is now unlatched [Music] [Music] Mike talked about you see him getting his feet getting his feet set that's right Dan You' ask if I got open the hatch so when you go out a zv1 just like Jared here is ev1 that's that's typically the role for for you to open that hatch and guys have to draw straws fever 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 Zer psia you see that in the bottom left hand side bottom left corner of your screen um our four polaron crew members um have 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 [Music] reached got SpaceX I'm unting the hatch now Jarrett now opening Dragon [Music] 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 on the forward [Music] hatch this must 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 [Music] operation center of the hatch actually has a window the hatch is unseated copy give it another P hatches several in turn copy we see [Music] it looking out that tiny window there in the forward hatch knowing he is going to have a much bigger window in just minutes [Music] Dragon Space X complete ev1 return to [Music] seat then E1 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 them repeat them one of the reasons we're doing that is just to kind of vent any of that residual and ev1 you are go for manual hatch open sounds like we got our first Audible the day is 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 [Music] W 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 SpaceX copies hatch open that is fantastic news uh for those that sp1 I'm looking at for seals initial view looks pretty good I don't see any V oration copy on Hatch [Music] [Music] 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 SE can you command open forward hat we're going to stall it open there is our first view of the forward hatch wide open to space forward hatch [Music] up 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 that structure you see there is check for ER 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 [Music] resilience these are the first views of the first ever commercial spacewalk and at the bottom of the mobility is progressing I have a feeling the crowd is about to go wild fex back at home we all have a lot of work to do but from year work sure looks like a perfect Road ni take even one I'm going to step into t matri one single-handed mobility demonstration Commander Jared isaacman now emerging Matrix one watching from the nose cone up down left and right are three pitch and roller three y two switching single-handed operations refine static and with Dynamic disturbance switching to left hand up down left and right are three maybe a two ditch is the four roll is a two Y is a two so these are the suit Mobility checks that Jared is operations Dynamic and with disturbance are all adequate test Matrix one complete Hut check 5.3 PSI 48% RH 33 deal 9 CSI SpaceX copies test Matrix one and HUD readout SC op Jack e1's good good 2 one good good D stepping into vertical translation we're going to start with the horizontal bars all right we're going to transition over to vertical i' say vertical and horizontal are equally workable slightly favor horizontal I'm going to do a Max reach left hands at the top of the mobility a at the midpoint you have good video we just lost our live video stand by one okay Switching over to Max reach switching P St facex I'm holding up at the max reach any ev1 go ahead and continue the operation uh we'll let you know we're back on with live video that and for your awareness Max reach L8 and the mid bar ma test Matrix 2 is complete C readout 5.3 PSI 33 decimal 9 Celsius 50% RH copy test Matrix complete and hard read out through off check e1's good E's good we good two good stepping in with test Matrix three three demonstration ev1 SpaceX for engress time go recommended Ingress time of 02 flow plus 4 7 Minutes copy that Ingress Time 4 7 minutes and dragon we're back on live video from the no gone Happ and space at1 I would say the handsfree demonstration is very comparable for the trainer in terms of the fo stre space I 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 happy that test Matrix 3 is complete the H readout is 5.3 PSI 47% R 33 decimal 8 Celsius and stepping vacuum Max reach copy test Matrix top of the mobility Aid and uh let's get a Quick Crew off check e one good e good good good happy that okay uh Max re whether it's left or right hand seems to be about the same top the mobility Aid and then the mid R copy we see it checking up from the bottom any go back SpaceX negative we got about 1 minute until ev1 Ingress Happ have 1 minute it's gorgeous you want to you get right1 we're checking out your helmet cam now now I'm checking out your no K right now and looks pretty good cop we those see looking at us all right we're coming up about that 024 timer time through check for in E1 good e all right than ja ev1 that's for the huge team effort that it took to get us to this point we know it's just to start then I'm transing back in the vehicle and face at TV1 we taking a quick look here the hatch Shields from what I can see so far they look pretty good copy on the hatch seils and stand by for transition to read off reset face this and 1 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 is in progress calling out numbers right now though we're doing you just heard copy Arthur call up three off resets 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 thrust or 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 BX attitude reset complete ev2 go for erress there is Sarah's clear to crew check for ev2 E e1's good EV good good two good eved is going to go stand on 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 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 FS look good I see a little bit of a bulge between 14 and [Applause] 13 so you're hearing Sarah call out some more of this 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 this scenario just pop it back in one final between 19 and [Music] 18 but might be best reated and hatch closer SpaceX copies can you repeat the location Eva complete between 19 and 18 all right I'll track that and uh ask again when you're Ingress cppy edq is exing with EAS 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 us work here cuz we want to do this 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 happy all I stay all three three transation AIS I'm having certainly cross Pur movements forward back I am inducing a bit of roll left right and up down a bit of a tip but all are achievable right in the three y a three BR a four and P the three the than for the next man stepping into vertical translation SpaceX copies and ev2 for awareness for tracking in Ingress time at O2 flow 59 minutes Cy 59 minutes horizontal bar definitely prer and I'm not able to stabilize my body with single hand right stepping into Mass reach do you have visual a firm we have visual on the nose cone copy from bar four to Bar two from top down and similar reach from bar two up to Bar four SpaceX copies reach and8 test one con SE pressure 5.25 33.8 Celsius 37% humidity SpaceX copies HUD readout and test Matrix one complete Happ 7 p62 like we mentioned before views going in and out doing during excuse me due to those ground station uh coverage gaps yeah we we C 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 are actually pretty good we're hearing the voice of mission specialist Sarah Gillis our fellow space xer on her Space Walk got just got about a minute left and then she's going to start heading inside and and St with a little more work I can actually get between almost bar one and bar four on that space has copies and you could see the Earth dark and we flew into like an orbital and T to trying to combine them so we'll call that conce PE pressure 5 27 38% humidity 33.7 cius SpaceX copies Matrix complete and H out stepping into H demo are able to engage and disengage my feet copy that D2 and once you are able to engage disengage we'll actually have you start Ingress we just over 59 minutes O2 flowy with that needing at indress Pro check for indress good stey coming on in all right and just like that Sarah's going to start making her way in clear 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 out it as well when ready to copy ready 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 report if you can see that Che 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 fing again between 12 and 13 copy you're go no mostly between 12 and 13 right now SpaceX copies at 12 if you can you're go to address those copy and lo 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 back one 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 D2 is clear 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 driving close you're good Cy depl handle a fing 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 [Music] hatch it sounds like we might give the motor a try he confirm the hatch is visually indicating closed Comm hatch is verified L hey command Eva hatch closed Eva hatch closed all Dr those 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 good one check secondary O2 valve Clos cing supp one I'm good TV1 closed 82 plus 41 F to [Applause] close a couple of real big moments right there Sarah was able to make sure eess oneop secondary FL is closed and agree EV press one she was here ble 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 tick up just a final confirmation everyone confirmed secondary O2 vales are closed one close 14 and we're through one for 8.3 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 spacewalk itself suit 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 one 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 right at about a 14 uh or so PSI and we're also looking at what the partial pressure of oxygen is cuz we want to make sure takes helmets off and everything fcking 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 fan 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 we're taking in that oxy 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 it did that was that was that was really cool to to see him 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 is tough X we're about 2 and a half minutes from Ted's 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 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 that I think is kind of cool is Max reach cuz like just going 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 face 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 and really for for Humanity CU 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 good to see you yeah 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 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 cute zerog 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 innov ailable breaks to allow the crew members to adjust during oh sorry I thought we were going to get something there the the Teedra sent 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 on we're good F you 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 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 8 and then we'll let it hang out there for a couple 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 1 hour and 13 minutes um it flew by so so quickly um six on cabin pressure approaching one PSI on P2 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 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 suit off uh our Eva clock's going to continue to count until we hear the call for Eva uh operations complete from our core orur 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 Puro 2 environment in the suit using nitrox before they get out Nitro 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 we're just going to keep ping out should hopefully be getting video back from ground stations pass seven and by for transition to repress 2 at 8 decimal 3 okay copy that SpaceX we're following along ref two at 8.3 yeah so once we transition to repress 2 once we're at about 8.3 PSI we'll stay there for about 2 minutes and then once the cabin gets up to nine 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 Clos 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 uh 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 ground 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 refes two Che ev1's good good and yeah that com we're hearing half side before we get the Le Che 9 the continual checks with all four crew members to make sure that everyone is good um if the answer to one of 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 9:00 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 time we need ref press two [Music] stop Dr space with you in Eva repress to stop waiting 5 minutes for theral [Applause] [Music] stabilization St that St we're tracking and pro for your awareness we do a positive ref press R we are 30 seconds into the reck like we mentioned earlier uh right now the this repress is being done with nitrogen um once we get awareness pp2 is 1 dmal 35 halfway there suits are 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 just one more minute yep reminds me of when I was a kid swimming in the pool you know time to get out just one more minute I mean 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 professionals they know there's a timeline minutes into the 8 Minute Le check throughout one's good one good you good pp2 just passed 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 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 in 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 uh 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 of Eva operations complete and that's when our clock's going to stop uh our space walk did start today at 3:12 a.m. Pacific 1012 UTC it's 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 halfway through the Le Che posi 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 four W hatch is properly sealed and and [Applause] shut it's very similar to 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 [Music] yeah big bigger volume evation Period start three minutes all right so we we hit X we're tracking we 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 to 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 [Applause] [Music] repress it'll it'll slow down a little bit um [Applause] for slow down a little bit for the remaining 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 [Music] [Applause] slow really enjoying these in Cabin views everyone gra for this L cheex is looking good so far but we're still going to wait to pull yeah probably that space TR we're tracking sometimes it seems as though the the feed freezes just cuz everybody's relaxing as the we're up on S minutes in Le check it's 9 decimal 7 pp2 is at two enough the final final minute of our leak check reports in the ground everything's still looking good [Music] or Jared report down that partial pressure of oxygen right at about two once that gets to about 2.6 we can essentially stop flow of that pure oxygen to the creu suits is like 2.6 is right where we want to keep it when we're at our final pressure Dragon space successful reck standby to restart refest C face we follow great news there successful leap check of the cabin all right crew we're in Eva repress 2 as a reminder Eva repress 2 will complete when either P2 reaches 2 decimal 62 or cabin reaches one atmosphere right now we're coming up on 10 psi for cabin pressure and cp2 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 up once that gets to about 2.62 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 is our Target for today uh and then our repress will be complete so uh this will go a little bit slower than the initial repress 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 what 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 are words are really hard right now um and uh we haven't had to utilize 2.3 pp2 targeting 2.62 cab pressure is at 10.3 if I was a betting man I'd say we get to the pp2 threshold first at that time U will switch to nitrox [Music] the hey good news there Interruption he wanton Dragon SPX we concur with e call [Music] 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 about 2.6 so we are continuing to progress uh pretty well 2.4 10.55 however as Dan just said this this portion of the recess 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 tests 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 one around and see how well you can stabilize yourself and and and then rate that activity on a scale of 1 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 Skywalker as 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 night and we're back we got views again St Tex is with you reminder to start manual timer on nightclock got St we're standing by there it is Bo started we're on Nitro Pursuit having P2 is two decimal 6 and cabin atmosphere is 11 one one death 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 and a 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 one good Commander Jared ISAC man continuing to check in with his three fellow Che secondary 02 valve open ev1's open ev2 is open one or yeah 4 One open 42 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 partial pressure of oxygen so we did hear that they've stopped the flow of pure2 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 cooling um so we're switching over to Nitro just to 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 uh 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 hanging 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 [Applause] we're four more four minutes into the open walk out 72 is 2 decimal 9 cam pressure 12 decimal 5 a [Applause] 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 yeah see see and Sarah gets a poker 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 to get up there and do it incredibly uh and then to the right of uh Sarah was commander Jared isaacman uh who was the uh first who performed the first EV 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 uh 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 period 3 cab pressure 13 decimal 3 Scott is actually our poison 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 Jered and Sarah go out and do those Mobility tests uh Anna and kid uh their one of their kind of main roles was being the eyes back inside if 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 keeping 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 the Evas were underway all right work [Applause] work coming up on 14 PSI again we're we're already at the the oxygen levels in the cabin that we'd look 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 we're 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 [Music] 1 I want to review a few things so when the timer reaches 13 minutes we're going to uh shut down the Nitro FL the suit then we're going to close secondary O2 valves and then you can vent uh use your manual vent valve in the plate uh when you're visor do not disconnect themop out copy one one good two good Dragon Space X we are less than 2 minutes from a teed's Handover but copy your call and plan we concur 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 checking Eva repress is complete continuing suit wash out Happ 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 y 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 minut to go 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 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 michig 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 500 a.m. Pacific uh we had there it is arming disconnecting nro and [Applause] yep all right check secondary O2 valves closed ev1's closed ev2 closed score one closed scort two closed all right you're going to manually vent down [Music] [Laughter] [Applause] [Music] [Applause] see Mr ringing check box yeah everybody smell that space Dragon SpaceX EV operations complete C that space X we show the same nice job for everyone uh and everyone in SpaceX made it possible all right Tex n all seats push the talk to manual armed execute space wow if you're just joining us we just heard the call out that EV Eva operations are complete which marks the completion ev1 uh com check on manual push talk manual push talk loud and clear all right that's the crew just switching off just switching off from Vox and back on to the push to talk that silence um really that's it that was the first ever commercial spacewalk um we started at 3:12 a.m. Pacific time which put which puts us at uh 1 hour and 46 minutes the four astronauts on board Dragon resilience performed a suited pre-breathe process to acclimate their bodies for the reduced pressure after that cabin was vented and the hatch door was opened and Mission Commander Jared isaacman he was the first to exit the spacecraft he got out there we saw him right as we were starting to get into that orbital sunset uh he was able to complete all of his tasks before he ingressed got back inside a dragon uh we did that quick attitude adjustment and then it was uh spacex's own Sarah Gillis the second exit the spacecraft do her 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 Menan have been supporting The Space Walk throughout from inside they went through the same preb the same depress process as Jared and Sarah they did a space walk too today um and everybody's reporting back healthy um and just I'll say it again because all the stat heads out there I know you guys are tracking our official start time was 3:12 a.m. Pacific and our official end was at 458 a.m. Pacific that was 1 hours and 1 hour and 46 minutes of space walking time uh next the crew is going to prepare for post Eva operations this is uh powering down 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 e complete and it's uh you know the the work isn't completely done yet they'll also have to perform some comms checks uh along with some additional tax tasks before uh their seats are rotated back into their preeva position uh and all in all it's wow just an incredible view we've said it already a couple of 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 yeah copy that SpaceX and we are ready for your seat rotation SPX incredible news yeah we're moving into sea rotation so again after that crew will be able to get out of their suits and that'll be the end of a just just a really successful day um hour and 46 minutes of space walking today uh so the player on crew they're back in their seats inside Dragon completed a successful space walk first ever from Dragon a massive congratulations to the crew all the teams in SpaceX who made this possible this was space walks are hard and this was an incredible amount of work over years to get ready uh special thanks to Mike Hopkins hopper for being here with us today sharing some great insights always good to have somebody who's done the thing to help you explain like what's happening that was awesome not only having done Evas himself but also he's a dragon rider he commanded the uh crew One mission so it was it was great to have him now uh Polaris Dawn is the first mission in the Polaris program that will demonstrate new technologies conduct extensive of 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 ex 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 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 [Music] let
