e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e 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 they're so good 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 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 long 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 space walk 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 per it really is and probably one of the hardest I think parts of the suit to design is the gloves right because you you hear us use the term it fits like a glove right we use that a lot but but you don't realize how much you use your hands when you're outside on a space walk as opposed to say your feet when you're you know because in space we don't use our feet or 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 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 checks 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 lead 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 leag check uh because now you know that you're ready to go so today's going to be kind of unique because all four of our crew members are going to be like doing The Space Walk they're all going to be exposed to the vacuum of space but I mean even when you did space walks it it's never a solo act right like you're always out there with a partner you you are it's uh it's extremely important in fact one of the hardest parts about our training for space walks is what we call incapacitated crew and so you need to always be able to get your crewmate back into the airlock if something should happen if uh if they should no longer be conscious and and something of that nature and so we we actually do spend quite a bit of time and that's why it's extremely important for us to go out in pairs because things can go wrong um and and so you want to be prepared for those those moments yeah U that's a great Point Dan to make that um while only Jared and Sarah are going to be somewhat exiting the space Craft 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 three folks outside on a on a spacewalk um and so yeah that's a that's a big deal deal and and kind of exciting you know one of the one of the things we do on the on the space station of course is We Have astronauts that are still inside and if we do get into those emergency situations they're there prepared to help us uh get back into the airlock and and uh and get unsuited and and things of that nature so of course when you have all the crew it just makes you think about those emergency situations probably in a little bit different way than we than we do on station yeah and hey if you're just tuning in we are still waiting to really kick off our 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 sex Dragon um ev1 is completing GL zipper closure but at this time we are ready for seat rotation TOA be that for seat rotation can you confirm crew is ready with the current gloves of props all right I I guess they just needed me to to say it was coming soon and then and then there it is uh but uh we are going to hear the seat rotation coming up soon again they're in their recline position and I'll do stand by get to the seat copy standing by so they're going to get those seats rotated and then we're 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 want all the way in the bottom left corner that's your dragon that's your dragon cabin pressure that's in PSI ready for seat rotation space siiz 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 if you're ever using a scale you zero out the scale before you put something on it it'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 seat rotations complete so now they're going to start doing that tear getting readyy and can I get a confirmation of completion for the call out in two decimal 18 complete copy at this time you are or 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 2 and uh Scott will be support one uh also Scott and Sarah are switching seats uh I perhaps they already cop you stand by for HUD power for pressure centor 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 uh is in that seat he's going to be in that seat right now but once we actually get ready to open the hatch and everything he's going to be positioned kind of over by the hatch and then Sarah ev2 is going to be in one of those Center seats then you'll have Anna and kid on either side Dragon SpaceX suit Huds powered report results of primary sensor HUD checks in three decimal 2 so again that's our that's our SE layout we just heard the Huds are powered on so they've got heads up displays actually being kind of projected on their visor in their helmet which if you if you've ever seen space suits 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 this the suits and head check out complete all nomin copy swapping the backup sensors stand by to repeat High 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 technology uh you know look it's our first live views inside Dragon resilience for this morning that's fantastic yeah I think this is the definition of chilling yeah so they're 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 H checks the crew is going to check out those heads up displays one more time real quick check back copy good Huds returning to primary standby for helmet camera check outs 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 suit pressure temperature basically it's a way to kind of keep an eye on things and we were talking about a little bit Mike but on the Emu is a little bit different yeah the Emu is certainly different uh a lot of that kind of information is on a on a display way 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 because I'd feel the pressure of I got to get a lot of things done I'm running out of talk yeah all right um so so they're they're going through these Hut checkouts again pretty soon Dragon Space X powering on helmet camps 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 utiliz 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 just like see good video oned no and almost double check your work copy checkouts 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 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 well space repeating checkouts are complete Huds are going to remain powered proceed to step three decimal 3 operations review through 3 dmal 8 and Report when complete happy inter and and the reason it's so choreographed and important is because you only have so much time outside right you only have so many consumables that allow you to go out there and so you want to take advantage of all of that you want to have every step very well scripted so that so that there's not a lot of wasted time now that being said it is nice when you're out there once in a while to just kind of take a moment look around enjoy the views kind of trying to absorb where you actually are which uh can be pretty incredible as well every every once in a while guys I'm a little tired I'm gonna 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 are support uh crew members are really going to that's kind of one of their one of their primary jobs during The Space Walk is to 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 gas coms 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 12 feet 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 85t 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 tether there's I feel like every time I watch there's like there's no way in heck that this thing isn't getting snagged on something no you're absolutely right because everything and and you talked earlier about making sure there was no loose items in the cockpit right because when you open that that hatch uh things are going to want to float away if they're not tied down or stored or anything like that so when we go out on a spacewalk not only do we keep us Tethered to the spacecraft but any tool any part that we take out with us also has to be tethered and it can be quite a challenge to manage all you'll open up a bag and there's there's 10 pieces of Hardware in there with 10 different tethers and they get all tangled up and and it can really be pretty challenging it's important though um we simplified that a little bit for this Mission um 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 Shar they're kind of moving around right it's it's very easy in in this environment where you're floating it's like Dragon Eva off you complete who are in position for Eva nice excellent cop Cent position but you saw Sarah kind of move the tether out of the way and the part of that is that's actually impacting go to command box push a talk all seats and so this will this will be one of the unique things about the space walk today it'll it'll feel familiar if you've ever if you watch some of Mike space walks the crew is going to go over to what's called voet set go the com check ev1 com check ev2 com check support one com check support two com check SpaceX copies all good coms all four [Music] crew 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 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 about 90 seconds from EV 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 suit Purge and that's going to be the official start of our space walk today so we're we'll get through the the final goes and then we'll see those visors get closed oxygen start flowing and we'll be off I love how everyone look so calm and collected right now I think that's 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 ort visor down ready for secondary O2 flow initiation and crew is go for spacewalk verify your bers are closed secondary O2 B is [Music] open and that you are go the EV ev1 is go ev2 is go support one is go support two is go Dragon bace X initiating secondary O2 [Music] 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 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 pure too 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'd be pretty tough to do and and as we talked about earlier that's why that Mobility is so important because uh when that suit is pressurized like that it it can be challenging to move around absolutely so here on your screen we can see the polaron crew now with their visors down the Eva has begun we are beginning to flow that uh O2 through now we will of course bring these views to you as we have them but due to ground station coverage they do come in and out here and there um but every moment that we can we will certainly be sharing these with you um I also wanted to point out quickly that the the the window near kids feet was so much brighter than it was uh just even five minutes ago we're going to be seeing that uh in start contrast as soon as we get uh the Eva or with the hatch open and ev1 out there yeah it's kind of interesting you you you mentioned that because as you're going around the earth as fast as you are right in in 30 minutes or 45 minutes or so you can be passing in and out of that sun and and going into Shadow and and so that brings its challenges as as well because the temperature um can change pretty drastically just in those transitions from night to to Daylight and and so there's a there's a it's an interesting moment when you're passing through uh through that time that's actually one of uh the reasons that the visors have this new coding 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 Space X a reminder after the initiation of primary O2 flow ev1 ev2 will need to adjust Vox threshold low following primary O2 flow initiation B one copies D2 copies Dragon SpaceX secondary flow Purge complete close secondary O2 valves and Report ready for suit [Music] pressurization ev1 closed ev2 closed support one closed support two closed X Dragon is ready for SE pressurization initiating primary O2 [Laughter] this is normal this is with the air flow coming through uh the crew members 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 left hand side of the screen so we can see that suit pressure going up um and we're able to keep tabs there um as well with the dragon pressure so Dragon uh on the far left Circle that's the pressure within the cabin and then suit obviously that's the pressure within the suits so we'll be actually be able to and I think we've kind of been able to see it already um that these suits will inflate a little bit um look a little different and we were talking about the the visors before so when they're in the sunlight that coating will help keep them cool and not overheat them and then when they're in Shadow it'll help keep them warm so uh and it's also like your sunglasses as well right serves that purpose all right so at this moment the suits are getting their primary pressurization this takes about three and a half minutes a little bit less and then we're going to go through those actual suit leak checks I the crew will probably get a reminder they have to stay really still when we do those leak checks and I always was kind of wondering like why the heck and like if you if you bend your arms you're actually going to start you know changing the volume inside the suit that'll cause pressure spikes and so that's right you got to stay really still yep and then after after we get through the 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 Environ just to continue purging all of that excess nitrogen um on report complete ev1 open one open the part two open and right there they they finished the purge and they did a quick uh reinitiation of that secondary flow check resp second flort complete give one close support one St Tex to conf Second [Music] CL these handles that we see Jared holding on to these were one of the addition uh or uh customizations for this mission that we talked about earlier support one STX cont [Music] [Music] we got you all right copy got the one Dragon space beginning to the check evaluation and then still for the [Music] [Applause] check 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 comms 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 they we got four good leag checks on their suits and now they're going to be in this final Suited pre-bath 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 nitren out um and we started pre-bed just two two hours after they got on orbit just like 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 we when you were doing your space walk yeah so we were past the kind of the camp out phase free breathe uh but that's how we used to do it 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 start about 6 hours prior to going out the door uh but it's not two days prior it's worth noting uh along the lines of training and how the crew prepared for this mission that all four of our Polaris 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 it's it's the first time that you're in that suit and it's actually a vacuum around you right and there's just something mentally that I think is important to put people through those moments before you actually have to experience the first time in space yep we we saw some of the unique ways we train the crew for this and I mean training for space station spacewalks 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 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 him train we'll be back on board with cameras in 3 [Applause] minutes so our CT just called up we'll get we'll get views back on board in about 3 minutes as Kate talked about earlier we're using ground stations for our video coverage all of our communication with the astronauts are through tedris so tracking a data relay satellites so we have we'll have constant audio but that video we need those ground stations uh but right now they're just they're in that pre- uh that final pre-breathe still we started our space walk about 13 minutes ago when we initiated O2 float to the suits the time is 3:12 a.m. Pacific 12 10112 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 spacewalk and and then after after we get through the pre-breathe we're going to get to cabin vents so you know what's what's going through your head when you're like man it's happening the 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 you're fifth you kind of understand how long it's going to take you have a better appreciation for how long it's going to take and so you literally find yourself in these moments when when you're kind of waiting through this pre-breathe or you're waiting for the airlock to depressurize just kind of find yourself just floating there kind of zoning out trying to keep yourself calm and relaxed and and until that moment when it's it's game it's game time yeah now just a quick mention we about a minute out until we uh get those views back uh inside the cabin um The View that we had previously was our Dragon tracker which uh if you want to see where Dragon is you can actually look that up as well um we have it on our website spacex.com 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 three um and then Anna is on the far left side and Scott is on the oh yeah we can see it there on the far on the far right side um and also just a reminder uh their their call signs for these Eva operations um Anna being support two kid being support one and then Sarah being ev2 and Jared ev1 representing uh that Jared will exit first uh do his activities which 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 in 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 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 Eerie 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 state [Applause] of T1 go copy initiating Caron venting that is great news exting so uh that breathing of incre a pre-breathe where they were breathing increased oxygen we just heard that uh they're good they all all four crew members gave the go uh so now we're going to vent the cabin yeah in in total this will take in total this will take about 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 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 and Dan 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 CS from the crew they're they're monitoring along 81 P2 we're going to hear that kind of we're going to hear that chorus pretty frequently you do those kind of frequent like checks and I know you guys did something kind of similar where like you have to pause and you know check your gloves that kind of stuff we we did I I will tell you one of the interesting things watching this uh live right now the difference is how quickly the depressurization is happening here versus uh what my experience was and and so you talked about being able to clear your ears and all that you're not giving a lot of time for your you're not giving a lot of time for your your ears to adapt to that lower pressure so this this is seems pretty quick to me yeah break breaking new ground with this new suits new operations for everything we're at about 4.5 we're going to see that tick down it's going to get down to just under one and it's not going to go all the way down um and then what we'll actually see is we've got a capability to open the hatch automatically we've got a motor in it uh 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 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 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 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 us for the first time but we're going into this with a whole lot more information than they had back then we know you need handrails or it's going to get real hard real quick that's right that's right yep we did we did also hear uh dragons moving into its uh it's Eva orientation essentially we're going to point the trunk at the sun under 3 PSI I think it's also interesting you notice that the depressurization has slowed down 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 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 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 good oh we're good two good yeah you really have four Mini Spa or spaceships in there press approaching 2 PSI I guess that means we have four aliens in there too that's right drag 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 into Hatch open [Music] 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 Cal and we're at it's kind of interesting because we're at a very critical phase ah 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 tick down Dragon originally designed to be able to still operate in a vacuum that was some of the emergency situations I know you trained for Mike we did make some modifications to this one uh to essentially turn Dragon into a functional airlock um we added some additional uh vent paths um we do use like some of the same ones that you guys use to like pressurize the vestibule and stuff like that um that are actually in the hatch but we've got a we've got an extra one in there to to be able to essentially do that deess as quickly as we did uh but we're going to we're going to see that get down to a little under one and then we're going to see Jared kind of jump into action he's going to unlatch the hatch and then he's going to give it a little pull to break the initial stion and then we're going to be able to uh 1.5 psia all sus look good one Cofe it's one thing to note that while we have been progressing through this pretty quickly we did have the capability to pause if any of the four crew members needed to uh you know take a moment to you know let their ears um come to equilibrium or just kind of get comfortable again um we did have that option but everything has been going really well so far we haven't had uh to to pause cabin venting and if you're just tuning in heck of a time to do it we're about a little under 28 minutes into the uh into the spacewalk today which again that started when we started flowing O2 to the suits of these crew members that was at 312 Pacific 1012 UTC we just heard that dragon's now in its Eva attitude complete so again we've got we've got dragon's trunk pointing towards the sun 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 intern when we were first starting the training and and so now to see him as a as a core and uh is it was pretty neat very similar to Sarah who also started as an intern yes yeah right we're coming up on one PSI you might see you saw the light change a little bit through that window as we 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 CU you don't want thrusters firing off when a group 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 C here we go Mike did you get to open the hatch I did you did yes yeah when you when you go out as uh G hat open front Dragon SpaceX for E hatch open prep confirm K to open [Music] hatch that is great open SpaceX copies Dragon you or go to open hatch go excited space 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 uh hatches Vis indicated open SP copies stand [Music] by should see him give that hatch a pretty strong jolt to release that stion hatch is now unlatched as Mike talked about we see him getting his feet getting his speed set that's right Dan you'd ask if I got opene in the hatch so when you go out a zv1 just like Jared here a zv1 that's that's typically the role for for you is to open that hatch and guys have to draw straws fever get 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 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 and just shortly after uh the crew got into orbit uh so Dragon Space X Target pressure [Music] reached SpaceX I'm on seating 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 pretty exciting for Jared because that center part of dragon Space X that's a good brace for have you repeat the [Applause] [Music] operation center of the hatch actually has a window the hatch is copy give it another [Music] call hatches several in copy we see it looking out that tiny window there in the forward hatch knowing he is going to have a much bigger window in just minutes Dragon space xent complete ev1 return to [Music] seat and ev1 copy transitioning back under the display so again one of the reasons we had Jared do that was to Dragon Space X we're actually watching that hatch we're going to have you repeat the last operation sounds like they're going to have 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 audit of 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 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 will get see hatch open and hopefully we see it yeah hopefully we see a hatch open the hatch is open SpaceX copies hatch [Music] open that is fantastic news uh for those that G1 I'm looking at for seals initial view looks pretty good don't see any V or ination 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 SE [Music] [Applause] SpaceX 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 for hat up if you just jumped in we are 38 minutes into today's space walk and the hatch is open on Dragon first view from a helmet cam looking out Dragon SpaceX we see installed ev1 is go to [Music] continue that structure you see there is check for ER [Applause] I'm transitioning back from under the display space 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 so the first views of the first ever commercial spacewalk and at the bottom of the mobility I have a feeling the crowd is about to go wild there fex back at home we all have a lot of work to do but from here work sure looks like a perfect [Applause] ro1 I'm going to step into T Matrix One singlehanded Mobility demonstration Commander Jared Isaac men now emerging from testm one watching from the nose [Applause] cone up down left and right are [Applause] three pitch and roller three yry two switching single-handed operations refine

we see it checking up from the [Music] bottom any go back space negative we got about 1 minute until ev1 [Music] Ingress to one minute it's gorgeous get right1 we checking out your helmet cam now now I'm checking out your nose cone right now and looks pretty good cop we're no cone see you looking at us all right we're coming up about that 024 timer time through check for ingr e1's good e all right St back t one that's for the huge team effort that it took to get us for this point we know it's just the start then I'm transm missing back in the vehicle [Applause] and space at ev1 we taking a quick look here at the hatch Shields from what I can see so far they look pretty good copy on the hatch seels and standby for transition to read off reset face this and ev1 is clear all right so Jared back inside uh we we heard him going through What's called the test Matrix uh it's basically just a bunch of Maneuvers using different hands using the foot Mobility is inog calling out numbers right now though we're doing you just heard cop Arthur call up three off reset so we didn't use any of the forward thrusters while was out there we're re-enabling them putting us back in our perfect attitude before Sarah gets ready to go out the door fun thing to note it's still not a perfect vacuum inside a dragon is it's an open loop system so oxygen is kind of getting dumped into the cabin as this is going on so you got a higher pressure in Dragon than you have outside so we're not worried about Thruster pluming yeah now you mentioned Sarah um just like Jared she will have 10 to 15 minutes uh outside perform those same sets of Mobility tests as Jared uh like we heard the core do um with ev1 uh they will call out when there's one minute remaining uhx attitude reset complete ev2 go for erress there is Sarah's clear to crew check for ev2 E ev1's good Ed good good two good Ed 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 and these guys only have 10 to 15 minutes and it just like that yeah it it can go pretty quick and and uh but fortunately um look good I see a little bit of a bulge between 14 and 13 so you're hearing Sarah call out some more of the seal check there as as she's exiting out three seated SpaceX copies that report good pick so this was something we knew might happen um and 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 that's might be best repeated and hatch closure SpaceX copies can you repeat the location complete between 19 and 18 all right copy I'll track that and uh ask again when you're [Music] Ingress copy P2 is secting with e super exciting to see this our fellow space xer yeah Sarah Gillis now about to make her Space Walk e one I'm going to hand this back to you like we mentioned Sarah will be performing the same uh set of Mobility tests uh so we will do the same uh try to stand by and listen to those CS I mean I said it before lot of the square 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 nosecon Cy all I to stay in all three translation AIS I'm having certainly cross couped movements forward back I am inducing a bit I roll similarly this left right and up down a bit of a tit but all aable right into three y a three roll is a four and pitches a three for left man stepping

complete second two like we mentioned before four views going in and out doing during EXC me due to those ground station uh coverage gaps yeah we we coms 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 stre space has copy and you could see the Earth dark and we flew into like an or all right and test Matrix to trying to combine them so we'll call that conce two pressure 5.27 38% humidity 33.7 celius SpaceX copies Matrix complete and H out St into H Street demo I able to engage and disengage my feat copy that D2 and once you are able to engage disengage we'll actually have you start Ingress we're just over 59 minutes 02 flow Cy that just sitting up IND check for ind's good good goody coming on in all right and just like that Sarah's going to start making her way in here check those hatch seals again SpaceX copies on strier plates and ev2 I have one more ask for the hatch if you can uh check that it as well when ready to copy ready 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 check 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 holding again between 12 and 13 copy your go no mostly between 12 and 13 right now SpaceX 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 reaing that seal not quite able to reach the back bom so we'll proceed with clearing for hatch closure just like that we're already hearing about hatch closure it's incredible that these two Evas just in two blinks of the eyes are uh2 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 cying handle app 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 hatch it sounds like we might give the motor a try confirm the hatch is visually indicating closed hatch is verifi last hey Commander EV hatch close Eva hatch Clos all three is enabled Dragon SpaceX we see Eva hatch closed and pressure indicates good hatch seal standby for transition to Eva repress one and E1 copy go check secondary O2 valves Clos stpp one I'm good e1's close close one two close [Applause] a couple of real big moments right there Sarah was able to make sure Eva repress one copy secondary FL is closed and agree Eva repress one she was able to make sure that the seals were in good spot we got the hatch closed you can see round of a half PSI for 8.3 see the pressure starting to TI up just a final confirmation everyone confirmed secondary O2 valve close keep1 close close close close C gas and we're through one for 8 point3 all right so each of the crew just closed those secondary O2 valves on their umbilicals again that was primarily for cooling um during the space walk itself suit still pressurized by that primary and now we're going to start to see uh the pressure tick up inside of dragon 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 kind of pretty much right back at our 14 right about our 14 uh or so PSI and we're also looking at what the partial pressure of oxygen is cuz we want to make sure the crew takes helmets off and everything fre that plenty of oxygen in the cabin and then we're going to change that injection rate to just help with the mixing is microgravity 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 get rid of the CO2 right because as they'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 that was 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's time right it is tough we're about 2 and half minutes from Ted hand 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 I think is kind of cool is Max reach cuz like just going like that is you know not easy yeah and I think one of the other things I thought was interesting is you heard I think it was Sarah talk about the horizontal rail versus the vertical and how much easier that was for her to grab 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've be able to share with us uh throughout this morning's operations and uh contributing your two cense yeah no thank you it was great to be here uh just an incredible moment uh not only for the Dawn for all of SpaceX and and really for for Humanity cuz 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 to see ho 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 in available breaks to allow the crew members to adjust during oh sorry I thought we were going to get something there the the Teedra s and out so like we'll get it back but um so yeah just the fact that the 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 them so we're going to keep keep counting the PSI up until we get to about eight we are going to do another leak check on the way up uh to our nominal cabin pressure uh as you introduce atmosphere you're introducing temperature changes not just pressure changes and so we'll essentially we'll get to a nice pretty stable point when we're at eight and then we'll let it hang out there for a couple of minutes uh Let The Thermals kind of cancel out um that'll take about 5 minutes to do that uh this obviously has to be done to make sure we've got a really tight seal with that hatch as before we let crew get out of their seats move about the cabin anything like that want to make sure dragon is fully recovered this is we B we just use dragon as an airlock yeah and actually the info that you were talking about you see it there on your screen live with that Telemetry there in the bottom left and bottom right hand Corners um we can see the Dragon capsule and the suit pressur 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 oness approaching one PSI on pp2 I'm I'm sure for sharid and Sarah it flew by even quicker yeah we just heard Jared call down we're coming up on one PSI for po2 so what we're really tracking before we give the crew the go to get out of their suits is both the actual like just the straight up what the absolute pressure is inside um but also what the partial pressure of oxygen is we want to make sure you you don't have a hypoxic environment inside basically you want to get them they're going to be pretty much right back at the atmosphere that we're walking around in right now uh before they get their suits off uh our Eva clock's going to continue to count until we hear the call for Eva uh operations complete from our core or through barrial 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 we're just going to keep pying out should hopefully be getting video back from ground stations passing s and by for transition toess 2 at 8 Deal 3 and copy that SpaceX we're following along ref press two at 8 point3 and 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 9 we're going to pause the repress and we're going to do a cabin leak check this is another kind of critical check we did the initial one after they closed the hatch where you're able to do just kind of a let's look at the pressure is it increasing at the rate we expect inside Dragon yes it is um and so we were able to confirm that seals and everything looked good we're going to do another leak check now that we've got more pressure inside Dragon just to really make sure uh that we've got a good seal on that hatch before we finish the operation coming up on 8.3 we should be hope 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 ref Che ev1's good good and yeah that coms we're hearing half PS before we get to leip Dr monitoring check 9s a 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 depressurized now this repress seems to be going uh really smoothly yeah we're just about at 9: I'm going to say we're almost there and then it's going to tick up but we're going to pause at 9:00 we're going to do another cabin Le check so we should hear that momentarily two [Applause] stop Dragon space with you and Eva repress to stop waiting 5 minutes with stabilization we're Ste that STX we're tracking and impr awareness we do a positive refresh rate we are 30 seconds into the re check like we mentioned earlier uh right now the this repress is being done with nitrogen um once we get awareness tpmc is 1 deal 35 halfway there sus 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 yeah 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 me it it it speaks to to the professionalism for for Jared for Sarah for the whole crew really like that's that's got to be this is something they've been training for for years and it's got to be really hard not to go for those you know that extra 30 seconds but they're true professionals yep they know there's a timeline one's good good too 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 off we've stopped the nitrogen injections but again oxygen coming out of essentially 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 G 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 amb be in pressure the inside dragon's going to be right around 14.4 or so and I mean that's that's a little bit lower than what we're walking around it now but like if you're at a little higher altitude uh state in the country or something that's that's what you might be sitting in right now in your house and that's they haven't been at that pressure since they left her yeah uh but after we get all the way up there we're going to do kind of a final uh flush of the suits using that nitrox uh the C is talking about uh that takes them out of that pure oxygen environment and that's one of the final steps before we'll feel hear that call from Arthur evva 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 check still [Applause] 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 forward hatch is properly sealed and and shut it's very similar to a suit leak check um that we do in terms of sustaining a pressure and measuring that pressure over a period of time um and obviously the the leak check for the capsule takes a little longer than the individual suit leak checks uh but so far so good a little bit more than halfway [Applause] through yeah bigger volume start minutes all right so we we hit copy that face 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 of equalize and once that gets at a steady state you can do a a real no kidding pressure check on this hatch and so we're we're underway with that that's going to take a couple of minutes and then we'll hear the results and then look to resume Zoom uh with the repress it'll it'll slow down a little bit um for slow down a little bit for the remaining of the repress uh kind of kind of going in reverse when we did the depress that initial a lot of that atmosphere is flowing over um and once we got down low it started slow [Applause] [Applause] really enjoying these in Cabin views everyone gra for this is looking good so far but we're still going to wait to [Applause] pull yeah C that space for [Applause] tracking sometimes it seems as though the the feed freezes just because everybody's relaxing as the che 9M 7 pp2 is at two [Applause] enough the final final minute of our leak check reports from the ground everything's still looking good or Jared report down that partial pressure of oxygen r at about two once that gets to about two .6 we can essentially stop flow of that pure oxygen to the Cru suits is like 2.6 is right where we want to keep it when we're at our final pressure drag space successful check standby [Applause] toest happx for follow great news there successful leap check of the cabin refresh [Applause] too all right crew we're in Eva repress 2 as a reminder Eva repress 2 will complete when either pp2 reaches two 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 [Applause] 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 po2 that partial pressure of oxygen continue to tick up once that gets to about 2.62 uh we're going to be done flowing that uh pure oxygen to the suits of the crew uh and then eventually we're going to get to one atmosphere it's about 14.4 as our Target for today uh and then our 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 that the crew can do exactly uh these are opportunities for the crew to pause the repress and just um allow themselves to equil to come to equilibri equilibrium words words are really hard right now um and uh we haven't had to utilize 23 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 in the seat all right good news there Interruption [Music] keep Dragon pay X we concur with E1 [Applause] call continuing to repress the cabin we had a successful leak check uh and you can follow along with uh the repress along with the data there at the bottom of your screen um as Jared said we are targeting uh 14 about 14 psia for uh cabin pressure uh or when cabin pp2 that partial pressure for O2 reaches uh about 2.6 so we are continuing to progress uh pretty well 2. C 10.55 however as Dan just said this this portion of the repress 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 function 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 um both Jared and and we're back we got views again St Tex is with you reminder to start manual timer on nightx to we're standing [Applause] by there it is Fox start [Applause] [Applause] Nitro Pursuit C cp2 is two decimal 6 and cabin atmosphere is 11 1 one de 3 well it might look like the feet is frozen if you look closely you can see small micro movements there with fingers and uh the strap above Anna's shoulder um we uh unfortunately due to uh ground station coverage don't have video 100% of the time even though we wish we did that would be great but we can see that uh Jared and Sarah uh are not strapped into their seats of course because they performed uh their Evas or their space walks uh extra vehicular activities where Anna and kid remained in their seats the window seats so we can see their um safety harnesses uh still strapped in there um at this point in time we are continuing with the repressurization of the uh of the Dragon capsule Dragon resilience uh we had a successful leak check good Commander Jared isaacman continuing to check in with his three fellow Che secondary O2 valve open [Applause] give you one
