LIVE: NASA-Astronauten gehen auf "Weltraumspaziergang" an der ISS

and on the left side of your screen is Barrett and assisting them through procedures at a spacewalk are NASA astronauts Matt Dominic towards the top of your screen and NASA Astron Jette EPS towards the bottom right of your screen they have completed the pre-breathe protocols and are currently working to Dawn the safersit aid for Eva rescue they will then move into the crew lock portion of the quest airlock to do some final Communications and systems checks before uh depress depress depressurizing the crew lock to bring it down to vacuum to match that of space the go for depressurization is currently scheduled for about 25 minutes from now around 700 a.m. Central 8:00 a.m. eastern and about 30 minutes after that we should see the start time of the spacewalk that start time coides uh to win they switch the suits to battery power the spacewalk is schedule to last about 6 and 1/2 hours and it will complete the removal of a faulty electronics box called a radio frequency group from a Communications antenna on the starboard Trust of the space station they will also collect some samples for analysis to better understand the ability of microorganisms to survive and reproduce on the exterior of the space station and just now you saw NASA ashot Tracy Dyson being moved into the crew lock once she is in the crew lock they will begin to attach the safer or simplified aid for Eva rescue to the back of NASA astronaut Mike Barrett suit on the left hand side of your screen and floating into your screen now you can see the safer or simplified aid for Eva rescue for Mike Barrett suit the safer is sort of like a jetpack that they attach to the back of the Emu or extra vehicular Mobility unit the crew will have two tethers attaching them to the space station at all times during today's space walk but the safer serves as a backup should they get detached e e e e e 81 tcv Houston copies e e e e e e e on your screen you can see NASA astronaut Mike Barrett as they attach the safer or simplified aid for Eva rescue further back on your screen you can see NASA astronaut Tracy Dyson her safer has already been attached and she has been moved into the crew lock portion of the quest airlock Barrett will be joining her there shortly and then they will begin uh final systems and Communications checks of the Emu extra vehicular Mobility unit before beginning to depressurize the crew lock to match that of space the go for deess is in about 15 minutes from now we should see that happen at about 700 a.m. Central 8: a.m. eastern e e Houston mat on hillock we're going to step 60 I'm looking at uh pushing the TV button from Mike we're not getting a good wvs light possible rebu we're going to visually check we copy and Houston for some reason we're showing Reba off can we go Reba on Matt you're go to take the Reba on Owen makes sense maybe somewhere in the shuffle here it went back to off doesn't matter we're going Rea on and with Rea on we got a good wvs light now we copy and you just heard the voice of NASA astronaut Matt Dominic aboard the International Space Station called down to michig control Houston as he continues to work through steps uh to Dawn the safer and work through some final emu or extra vehicular Mobility unit configurations before moving NASA astronaut Mike Barrett into the crew lock you heard him reference seeing emu TV and powering that on this references the camera for the Emu which will help provide views outside the International Space Station as the crew Works through to today Space Walk and now you can see NASA astronauts Matt Dominic Matt Dominic and Janette EPS moving NASA astronaut Mike Barrett into the crew lock to to join his fellow space walker Tracy Dyson after they finished moving the crew into the crew lock portion of the quest air lock they will begin to close the hatch between the crew lock and the equipment lock after that is complete they will begin the depressurization process of the crew lock to bring the air loock down to vacuum to match out of space the crew lock begins at a pressure of 14.7 PSI or pounds per square inch to match the rest of the space station which is similar to what we experience here on Earth and now on your screen you can also see NASA ashot Sunny Williams Williams is the pilot for NASA's Boeing crew flight test mission the Boeing Starliner spacecraft launched the space station earlier this month and they are continuing to spend time aboard the station as part of their flight test for e e e e e e e e and we are now on a brief but expected Handover between satellites of the tracking and data relay satellites or Tess we should regain those video views from the space station shortly e you are seeing a live look inside the international space station flight control room here in michig control Houston towards the middle of your screen is the Capcom or capsule Communicator console position supporting today's spacewalk as the ground IV or spacewalk Communicator is NASA astronaut Steve Bowen Bowen is third on the alltime space Walkers list with 10 Evas totaling 65 hours and 57 minutes of space walking time outside the International Space Station supporting the team of space walkers on the International Space Station we also have the flight director today who is Rebecca Wingfield and the lead Space Walk officer Sandy Fletcher and now we have a live look back inside the quest airlock of the internal space station you can see the team working to close the hatch between the crew lock and the equipment lock of the quest air lock um aboard the International Space Station the space Walkers are currently in the crew lock portion of the air loock and then once the hatch is closed they will do some final suit systems checks before beginning the depressurization process in the equipment lock portion which is the portion uh closer to your view we see NASA astronaut Matt Dominic and he is supporting The Space Walk as the prime spacewalk support he's going to be joined by NASA astronaut Janette EPs and then also on your screen right now you can see NASA astronauts Sunny Williams and Butch Wilmore who are part of NASA's boing crew flight test we copy five and 12 good numbers as the teams continue to work through procedures in preparation for today's space walk the International Space Station is currently flying over Southern Canada just north of Montana we should see the go for depressurization of the crew lock shortly after the hatches are closed and then we will have an official start of the Eva once the emus or extra vehicular Mobility units are switched to battery power we're expecting that to take place in about 30 minutes around 7:30 a.m. Central 8 :30 a.m. eastern and you just saw NASA astronaut Matt Dominic closed the hatch between the equipment lock and the crew lock of the quest air lock and we should hear that go for depressurization here shortly e e airlock One Step 76 and 77 are complete Houston copy 78 is complete we're working 79 and 80 uh we'll call you back shortly Roger e PC mik this is Houston you're now hot Mike good morning good morning and good morning will and airlock Houston step 79 is complete uh and you have a go for step 81 as well as performing The Crew lock b press section of the crew lock b PRC cardock copies we have a go in Step 81 and the team here in Mission Control Houston just gave the crew aboard the International Space Station the go to begin that depressurization process4 good copy mike ev2 check the switch deess pump power is off pump power is off Dy verify the deess pump enable LED is on that is on and with that we are stepping into the depress repress or the deess Q card2 on the UIA switch Dess pump power to oness pump power coming on in three two one on in a wait period okay next step deess pump manual isolation valve to open manual ISO valve is open monitor your suit P gauge your suit pressure gauge is less than 5.51 copy the crew lock is at 6.0 expect alert tone the gur lock depressurization process has begun the crew lock began at a pressure of 14.7 PSI or pounds per square inch which matches the rest of the International Space Station and is similar to that which we experience on Earth the pressure is currently down to about 12 PSI continuing to drop it'll continue to decline until it reaches that of vacuum to match space e1's at 4.6 on the gaug also 4.6 4.8 4.82 V1 is reaching five2 at five five on GPM is 5.1 ev1 5.22 at 57 5.0 here in a hum y9 me to 4.9 loud home just checking is that expected that loud hum C check hear you guys got you loud and clear okay are you hearing the same home negative ev2 holding steady 4.9 loud Mike ev2 ev2 we have you allowed and clear that's expected hum all right1 4.92 stable 49 lot louder than I expected and the crew lock pressure is down to about 9.9 PSI or pounds per square inch and continuing to decrease once it reaches about 5 PSI they will then conduct some leak checks You2 still St 4.9 the crew lock is down to 8 and 1 12 PBS per square inch as they continue with the depressurization process ahead of today's spacewalk is for the crew lock portion of the quest airlock is continuing its depressurization process it is down to about 7.3 lound per square inch once it reaches about five PSI they will then conduct some leak checks they will then continue the depressurization down to about 2 lb per square in before reporting some initial tether configurations and then once it gets down to less than half a pound per square inch close to that of vacuum to match that of space they will open and Stow the EV hatch how you doing Mike doing good 4.9 6.5 on the oh I see 615 the crew lock pressure is down to about 6 PSI or pounds per square inch on your screen you can see NASA astronaut Matt Dominic he is helping today's space Walkers NASA astronaut Tracy Dyson and Mike Barrett through the procedures and he will be the prime support for today's uh spacewalk robotics operations as well and he will be joined by NASA astronaut Janette EPS as backup support the crew lock is now just under 52 PBS per square inch once it gets to 5 PSI they will then conduct some leak checks is he still stable all right with the crew lock at 5.0 deess pump manual isolation valve to closed expect alert Zone deep manual is closed closed ev1 ev2 on your DCM switch display status until Le check question mark displayed and then switch display yes for two seconds follow the displayed instructions one copy two copies h ev2 we complete St cop and uh once you're there report that it's in that position and we just heard confirmation that we have two good leak checks on the emus or the extra vehicular Mobility units two in EV cop1 O2 activator Eva thank you on got a bunch of adjustable tethers in the way fing down I can see your finger you can probably see it better than I can I think I can got bring it over I got these adjustables out of the way way there go you got it on it yeah yeah yeah out of position press if you can grab it I can't I just got to get lower hang on I will it if you do that if you can't let's see got too much stuff in the way I keep trying y down down which way me y you're thank you you're welcome let's Che a look I see position Eva thank you no we can do that yes B this camera out of the way2 Eva copy station copy ev1 and ev2 are an Eva and uh might take your time to Res situate your tar and when you're ready I got the next step that stand [Applause] by okay ready for next step awesome step seven Dess pump manual isolation valve to open EV expect alert tone open valve is open happy for your awareness emergency m is also coming open and with those good leak checks the depressurization process of the crew lock begun is 55 at5 the crew lock pressure the crew luck pressure is now just under 4.4 pounds per square inch once it is down to two pounds per square inch at 5 expected right just up to 5.0 also once once it is down to 2 PSI they will report some initial tether configurations the pressure is now under 3.5 lbs per square inch airlock Houston uh since we have a moment here the Dess is looking good proceeding as expected the crew lock is now just under three pounds per square inch and continuing to decline I may relocate the adjustables in my mini work station there just to enhance visibility when we come in sounds like a good plan and we'll check each other over before absolutely e and the crew lock is at 2 pounds per square inch as they continue the depressurization process2 we've arrived at 2psi for the crew lock you can take the depress pump manual isolation valve to close deess pump manual ISO valve is closed doopy closed on the UIA switch depress pump power to off we are now in a brief but expected Handover between satellites for the tracking and data relay satellite system or tedris which provides those views from the International Space Station we should get those camera views back here shortly while they're at that 2 PSI they will report the initial tether configuration to Mission Control Houston once all of the tethers are confirmed and in the correct place they will continue the crew lock de pressurization all the way down to less than half a half a pounds per square inch and then they will open and Stow the one and Matt go ahead for tether config if you're ready to turn them over I'm ready to pick them up I think maybe we short loss or hand over my call the first time but you have a go to start T fig thank you and I'll pick up thank you Matt and uh Tracy and Mike and I can either lead you through your te config or you can tell me what you have and uh we'll work from there right well how about we just kick it off and then you tell us what we miss that'll work great okay so start all right Mike why don't we start with you at the Anchor Point that Steve good to hear your voice my uh right waist tether is connected big hook to the airlock d-ring extender Hook is closed and locked the small end is connected to my right fe- ring extender that hook is closed and locked I let me pull stuff in here you might actually be able to see my cheddar reels better than I down at your end all right so I'm looking at Mike's um's left ring extender has a Red Hook the gate closed Bel locked and here's other close is um sorry his yellow Hook is on his green reel clo black and black his green Hook is on his red reel and lo and his reels are locked the anchor is attached to wa wa both hooks are fate closed lock black on black and 81 Wast to right side connected toing extender eight with close black and B1 red is on the same heing Extender with the baril hook closed baril lock back on black the uhow hook the red reel is heads to the green rail with the Clos tail lock black on black and green Hook is on the red reel was black on black and the anchor for ev1 is on ev1 workstation fail closed unlocked miss anything we're checking to make sure Bally just double check that your reels are unlocked on for you and you have a good T thank you all right we got the green wheel is unlocked and red wheel is unlocked a good tether config and now you get to wait and stare at the hatch and wait for that pressure to get in range to get it open okay well while I'm staring Mike gonna U bring my feat down a little bit all right position somewh see so maybe if you could rotate so that your p is toward the forward side of the crew lock okay that might give a little bit more room okay I'm going to move forward for that and then I'll move I mean forward I mean bag and then I'll move the UIA the mechanism and we just heard confirmation of good tether configurations they're continuing the depressurization of the crew lock down to vacuum it's currently just under 1 PB per square inch [Applause] once the crew lock pressure is under half a pound per square inch theide of the air log imagine the rfg in that position and think about how much room you have and try and visualize where that cone is going to be relative to Tracy been kind of thinking about that be a bit of a squeeze I think we can do it though about the uh light reach I'll be reach him if I'm not on my umbilical I think have to come in on my right side and kind of carefully reach up there fortunately that's where the te is going to be left side up yeah you're hearing some conversation between today's SP a93 a gentle hug may be okay he said got a question about myit pressure I know we were anticipating the high but I expect to maintain this pressure it Dr the Eva no that that your pressure will bleed down over the next few minutes uh you know it once the relief valve seats uh and then it holds steady for a while and then you just kind of breathe it down uh the fact that the pressure is holding is a good sign that your Lea valve is fully seated and we'll be watching everything it looks good so far awesome okay thanks mik when I start to work the hatch if you could keep the Reel um towards you so hatway clear do all right I'm turning them down here now and I'll keep an eye at them thanks a lot crew lock is now under point8 pound per square inch as they continue the depressurization down to vacuum once it's at half a pound per square inch they will begin to open the EV hatch and stow it around that time they will also switch their suits to battery power which will Mark the official start of the Space Walk ch cre lock is now at 7 lb per square inch e e cre is now down 26 pounds per square inch as they continue the depressurization down to vacuum ahead of today spacewalk for those of you who are just joining joining us um we are covering today's space walk where NASA astronauts Tracy Dyson and Mike Barrett will exit the International Space Station to complete the removal of a faulty electronics box called a radio frequency group from a Communications antenna on the starboard truss of the space station they will also collect samples for analysis to better understand the ability of of microorganisms to survive and reproduce on the exterior of the orbiting laboratory in preparation for today's spacewalk they have already completed the pre-breathe protocols to prevent decompression sickness and they are currently in the crew lock portion of the International Space Station's Quest airlock completing the depressurization process down to vacuum here in the room supporting today's spacewalk we have flight Direct Rebecca Wingfield who you can see on your screen and then supporting as the ground IV or Space Walk Communicator we have NASA astronaut Steve Bowen just about to ask the crew lock is almost 2.5 pounds per square inch once it reaches this marker the crew will start the procedures to open the EV hatch after that step is complete they will turn their emus or extra vehicular Mobility units to battery power once that step is complete that will start the clock for today's space walk today's space walk is expected to last about 6 and 1/2 hours it was me oh I sound like bleed over somewhere yeah like I'm hoping there's nobody else on the loops with you guys how's the gauge looking Trac did you did you guys hear that little BP I think before you before you guys started talking so must have heard the same thing you heard [Music] Y and Tracy we're looking for a pressure left 6 are pressure less than okay you have a go to proceed so Tracy you can open and Stow the EV hatch ready for the I'm ready I've got both backed back here thank you you have a go for the hatch you have a go for the hatch he M I'm going to do this in two steps I'm going to first slch it then I may need to reposition myself to uh swing it open okay Rog that and we just heard the go for the crew to open the EV hatch once that step is complete once that step is complete they will turn their suits to internal battery power to start today's Space Walk M can you control of my feet they have to come down towards me okay I got one of your foots got your left foot trying to keep mine out of the way all right hat is open awesome go your and for uh mat you can take the emergency EP to close that is complete okay Tracy and Mike uh we're ready to pick up in the post Dess so I'd like you to switch your power to battery and stagger your switch thres stand by okay going to B by and I received a 2p High message and I copy1 you're power bar right yes on ev1 power on ev2 all right rate zero I would like you to uh switch your display Pro to verify a functional display and ev1 has a functional display ev2 functional display UIA switch power ev1 and two two switches to off you want and two power switches off lights out C Al LED disconnect your SCU from your DCM and Stow install a DCM cover and Stow the SCU in its pouch when do we go water on once you get the you stowed and uh we check a couple other things then we'll take it on but not quite yet you'll get there got okay make sure my pouch oh my goodness my uh up no was that just Ice Crystal out of myu guys yeah there's a lot of particulat flowing around here yeah can we uh we turn off the UIA and you can reconnect your sdu to your DCM and we'll take a look at that a lot of water is it still coming out if uh I don't think we can do it yeah there's water everywhere okay let's get youru we connected to literally water everywhere now I don't think we should try it I think we need to turn the water off there's water [Applause] everywhere not on my and Trac the best way we can do this is TR if you can connect youru back to your GCM that's the best way to stop this all right live view C it's connected but I don't have it locked yes just work on getting it locked and I just want to verify the water was coming from the seu side I can verify that the water was coming from theu side okay I got ice all over my hands all right just uh work on getting your seu connected and uh I'm going to start working through the checklist for this your vision vision's good get a tone Reserve water on time left 30 cop the reserve water on and uh have you got your seu reconnected yet I have it connected I just I think it's locked all right work on getting it LO lock yet and Mike I just want to verify that you're still on the seu I have reconnected my seu and it is locked you can help Tracy get hers locked uh we'll good just thinking about how I unlocked well done okay so we both have your scus on and locked and that should that should help here the reserve water on time left 29 can I put on my on my gloves just want to double check that your seu is locked seu is locked okay so with both of you on suus and lock we're going to terminate for the day uh so Tracy we'd like you to uh shut the uh EV hatch and lock it work m a little more challenging and Tracy this is uh this one of the more difficult things you're going to do so one of the tricks you might use is using the large hook one of your large hooks from your waist tether and poke the uh latching mechanism because that gives you a little bit more room to get your body out of the way to get that hatch seated okay m do this in two steps okay and since my weight Setter is connected to your set yep take my uh do you think I can do it with a small hook yeah the big hook just gives you a little bit further reach and I know you know personally there are some days you need a little bit more reach just just whatever it takes you can poke it you get it off seat and sometimes it likes to go reseat itself uh so you got to get that momentum started to get the hatch over Center and then it goes right down you've heard quite a bit of communication between the crew and the team here in Michigan troll Houston The Space Walk for today has been cancelled due to a space suit cooling unit water Le leak that began right after the suits were put on internal battery power the crew is now moving back into the airlock and closing that EV hatch then they will begin the repressurization process my so you're going have to let go of the re yep that's okay my feet up toward your head a bit more there go got to unlock something here I got you a little bit more right all right now you can go a little bit forward forward okay good okayed and locked EV hat is thank you closed and locked that's good news lock I got a frozen finger so if I turn my glove heaters on that'd be great can I turn on my glove heaters yes you can you can turn on your glove heaters and uh that should help with your fingertips uh and Mike while you're sitting there just check the oxygen emu one two valves are both still open oy and Val both open and Tracy you just want to make sure how you feel in the suit we understand your hands are cold want to make sure you're uh uh feeling like your lcv G is working and you you can obviously adjust your your heating and cooling a little bit if you need to now I'm comfortable but I do feel a little warm all right we got water 24 minutes left on my just got quiet but I think I could hear the F still yeah as long as the so your fan still running there's a couple uh indications we'd like to get from you we like your water water pressure and your water gas pressure water gas is 15 water water is 15.1 15 and 15.1 that sounds good I would it see Reserve water on there yeah the reserve water on locked now it's just the timer that's going to be running uh you've got good pressures you sh as long as you're comfortable it should still feel good uh we're going to sit like this and have a little bit of a discussion uh before we determine exactly what our next step is you should be stable let us know if there are any changes uh now that you've actually got that hatch shut uh think about doing that again because it's never the same place okay but am I right are we ter you said terminate right yeah that's what we're holding for right now we're just discussing uh which way you want to go with this uh we're going to check all the indications and uh because the uh that Reserve water on is a potential indication that we were taking water from the suit and that leak was on the DCM side as opposed to just on the seu side uh there is a towel in the uh bags in front of you if you can still you have any water still flowing around or you want to try to clean up any ice crystals uh you can take care of that I'm not sure what else you're seeing there uh what do you you continue to see any ice chips floating around or anything yeah yeah there it's a little snowy in here but not as bad as it was when the Su was off um I uh I have ice on my glove still um and on my uh helmet but if it's all the same to you I not to hand at the moment to get into that bag get those you how you want to manage that uh are your hands getting warm again your heater working I hope um they not getting colder PR it does take a while for those heers to kick on and I've noted that after a while they seem to get a little bit too warm so uh let us know by a couple more minutes if they don't if they don't come on we'll talk about that as well okay did you have any water you didn't right no coming out of M yeah it seems all I couldn't tell where it was coming from the or DCM you could but it was all from you okay I got an Arctic blast all over my visor yeah just just ice was flowing everywhere yeah I wasn't sure if it was my uh it was on the outside or the inside I couldn't see anything out there for those of you just joining us you're seeing live views inside the International Space Station Quest airlock where NASA astronauts Tracy Dyson and Mike Barrett are in the crew lock portion they were scheduled for a space walk today to complete the removal of a radio frequency group as well as collecting microorganism samples shortly after they switch their suits out yeah not yet shortly after their suits were switched to internal battery power about 15 minutes ago the crew reported a water leak which was coming from the SPAC suit cooling unit on the space suits uh and after that call took place the crew went ahead and closed the Eevee hat on the space station and teams are currently working through next steps and so Tracy uh just a another quick question about your seu as you were did you get it fully clear from the DCM as you were removing it uh so you could verify exactly which direction that water was coming from or did you keep it close realizing that something was leaking I had it way clear in fact I was trying to hold it outside the hatchway the cameras you may have seen some SX um it was coming out of the it was coming out of the port that's um not Ming the um you're holding it in your right hand it was the the bottom um bottom right quadrant and um it was it blowing out of it to dead I couldn't see what was coming out of my d because had a layer of ice on my visor there I brushed it away and I could see the seu which I was holding out um wasn't out of the hatch but it but there was enough of a gap in the thermal cover that I could see the ice crystals were flowing out there and then um just like a snow con machine there was Ice forming at that port on the suu uh sounds like you had pretty good rate out of the suu I mean if you get a uh ice on your visor that quick and you had a pretty good Cloud good job getting the Su back on and loost because that definitely a little bit of ice build up that could have been a big problem thanks for getting that done yes PR good Steve um it was instantaneous as soon as I lifted the I unlocked it and as soon as I lifted it away it was a blast all over my um visor it wasn't until I cleared the ice I could see it was pouring out ofu C that those are good words that helped the the discussion down here a lot hey Houston also um I was happened to be out the gem window with I saw a pretty good storm going out that way heading Port um thousands of ice crystals just so you know that was a great words that helped a lot as well my fingers are warming up okay great great job getting the hatch closed as well thanks teamwork where the and Defector cold figes after some discussion here in the room of Mission Control Houston the team has confirmed that we will be terminating today's space walk following a spacit cooling unit water leak in Tracy Dyson suit that occurred after the suits were turned to battery power we also heard confirmation that the EV hatch on the space station got be setting a three getting a little bit cold in there uh Trac if you can do us a favor and just double check make sure you have the EV hatch closed locked and uh then we'll pick up with the Q card I can confirm that the is closed and locked locked okay and it's snowing understand is uh is your visor pretty clear now just want to double check yes sa for a little bit of ice the base but I I can see fine okay and uh based on the report of the amount of water we saw from the gem uh coming from there they were our one concern is the uh obviously the seal on the EV hatch uh so give us one last second to double check before we proceed all right so on the UIA we're going to pick up in the uh pre press card switch power ev1 and two two switches to on and verify that all uh both LEDs are break break want I just want to hear that if I go to SCU I'm going to be okay because there's water on thatu you still leaking water T I don't know but when I put on there was still water shooting out should be fine we can assume that it's there's water in there should be fine that should should be separated um but that's a good question we're all looking at each other and we we all agree we should be fine one last delay we'll do one check uh that section obviously should be isolated and the you you know how those electrical connections are made up in there it has a little bit of a uh insulation around and it's unlikely you would have gotten it fully closed if it had any uh anything in there to be concerned about okay because because I understand that when it's mated they're isolated but it was while it was unmated it was shooting water at my DCM so we can presume that water got into that connector electrical connector and I don't know I mean I'm sure itated but if there was any ice crystals in there you're telling me that wouldn't be able to get my Stu on and locked yeah but uh you know out of concern we're looking at just bringing you up without that without your power we've got plenty of battery power not going to be an issue okay thanks Steve we we'll get back to that set but just to confirm there'll be a normal Power on for ev1 correct for the Q card yeah we're going to wait on that Mike so we're g uh we'll wait on the command we'll bring you up with power we got plenty of battery power so this is not an issue uh so we'll bring you up on the seu and we'll leave her off at standby one hold e how you doing over there t I'm good M thanks how about you I turned my glove heer off so it did that's good to hear I turned off my glove I turned off the glove heater did the trick okay so we're gonna pick up here and the Delta is we're going to bring Mike up on the seu so I'll give him the switch PO for that and during the repress Tracy you should expect a battery amps High message which you can acknowledge but that's just an indication the batter's uh you know being used a little bit more than expected and that's there's no action for you beyond just acknowledgement okay thanks for the head you are seeing live views inside the International Space Station's Quest airlock NASA astronauts Tracy Dyson and Mike Barrett are on the other side of that hatch in the crew lock portion shortly after the crew lock was brought down to vacuum and their suits were switched to internal battery power power The Space Walk uh you can take power ev2 one switch to on ev2 copies ev2 only power coming up to on a good light dation and I see good volt 18.6 okay and for ev2 only take the power to SCU ev2 poweru expected tone so for ev1 and two uh we'd like to take O2 actuator to press e22 press verify between okay I understand both ev1 and ev2 are impressed check Ed the EV hatch Mev is closed EV hatch Mev is closed confir TC you are in press right I am iness he we want to take the IV hatch Equalization valve uh throttle stand by standby stand getting theault so must not be stand by but it sure it seems like a PR yeah once you get it there give it a wiggle make sure it seats I get that message oh no it's hold on and Tracy just as a heads up you know you might have a little ice built up in there so a little bit of uh might have to wiggle it shake it get it seated so this might take a little bit longer now it's off hold on it went off need tole on is all right TR understand you are in press you are in good indication for press correct D says and Mike just verify you two2 data up here as well we're down here know where your head is see my Reserve water on message it's um it's right have time four minutes all right so your reserve water on says 12 minutes as I said that's a dummy timer you have good pressures so you that's uh not a concern we see both of you impressed now uh so we are going to proceed from there check the EV hatch I is closed try yes it's Clos hat and is closed and now take the IV hatch Equalization valve and thle off to Norm to establish the required rate and um should we do that or expecting Ivy to do that yeah and Mike we would like you to do that because and Steve Matt I'm ready to pick up the reest Q card if You' like and understand step three IV hatch Equalization file throttle off to North yeah I think let Mike do that I'd like to have Mike do that to bring this up so that they can manage it and then once we get through the lead check at 5.0 uh that's probably when I'll turn over to you Matt uh we want to make sure we get a good seal on the hatch based on the possibility that there's ice there uh so we're g to we're going to do that leak check verify it at 5 and uh once we're done with that point I'll I'll be able to turn a r to you after that all right get in position here real quick let me know if you need me to do anything fine all right um I'm in position I have a hand on it and I'm going to start very gently fing the termination of today's space walk the Eevee hatch has been closed and they are now beginning the repressurization process as of the crew lock out don't want CRA it open too far too far we're starting to see pressure coming up so uh you should be feeling here in a moment right I should be about a third of the way between H nor how's the Press TP um it's good yeah let's definitely making some ice fly around and it's already starting to liquefy amazing excellent physics experiment sort of unplanned but good observations you're welcome passing one is what we're seeing the RC good see going through 2.3 [Music] and just is an FYI Steve I don't think I could reach this with the rfg here that's good to know that's very good to know thank you for that now without uh moving it out outboard a little bit a [Applause] lot the pressure inside the crew lock is now up to 3.5 lb per square inch and climbing once it hits five PSI they will wait for a couple minutes for the crew lock pressure to stabilize here the alert [Applause] Zone when you get to five you can take the off welome I see 4 five for five [Applause] ipsi valve is off we're going to pick up with our leak check all right so we're going to let things stabilize here and Tracy you might end up with a no too high usage rate based on the fact that you're coming up in pressure so there's a couple things you might get along the way let us know when you do okay well right now my pressure SC I think at 4.2 on the gug and2 4.2 copy 4.2 and how's the uh uh the hatch pressure gauge for you there Tracy that you're looking at it's reading um like 7.5 negative 7 on the negative side between 10 and all right we're just going to keep starring at that and hopefully it hold steady and then we'll be able to proceed once we get a good Le check I won't take my eyes off it this is one of those few times you actually want that that gauge not to move this one of the times you don't want that gauge to move right right the crew is continuing to work through repressurization procedures following the termination of today's space walk us spacewalk 90 and so Mike and Tracy as we uh get through the leag check uh as you look around and water starts to form if you guys can keep an eye on where you see puddles and water forming that might help the uh IB crew when they come in wipe up to know where you think the water wenty yeah Cy I'll tell you that at least on this end of the crew lock it was just crystals would uh run into the surface and start to stick there as we pressed up it was pretty random no big collections out at this hand all right that's good to know and uh every roet I form is already evaporated in the low pressure yeah I can see water on my uh helmet on my helmet not in it on it and around my bcmu interface that in and on were those are good words to use we don't need another issue yeah between 10 and on thetive side had a good leap check uh in Step seven and you can switch your glood heers to heers off1 glove heers are off all right just double check make sure there's no contamination on them there shouldn't be since you didn't go anywhere right ev1 and ev2 can take O2 actuators to IV work work is and we just heard confirmation of a good crew lock leak check as they continue the repressurization process and Mike uh have have you made it IV yet yeah you chose an IV with a good DCM okay that sounds good all right so Matt I'm ready to turn it over to you with Step 11 do you copy all the Deltas uh there are two two warnings that uh Tracy might get battery amps high and O2 usage high and uh we'd like to make sure that uh once you get the hatch open um that you understand where we're heading we've got uh you've got us into O2 acuator IV we're going to go into we can either go into 1.24 Z directly or we can use the one for the timeline that has the rfg stuff on it and just skip the rfg stuff and I understand Tracy's uh warning there for the O2 use high and the battery amps as well as the Tracy's on battery power and Mike is on Su power all right uh that sounds good and we'll pick it up with the XDP version on the timeline as opposed to the standard um or copy yep and that's 70- 0155 but for that I'm showing I'm picking up here in Step 11 of the the repress Q card I agree and it's all yours from Step 11 thanks for all your assistance happy controls than Steve thank St and Matt and Tracy's Trac follow the IV hatch Equalization F towards Norm expess was saying something St can you repeat I was just thanking you for uh the opportunity to work with you again very short L this morning hopefully next time we get a lot more work out of you as always appreciate the call voice in the uh in the nonexpected and uh Mike you you already have the shortest Eva I know of but this one doesn't count today so you still have your old record still hold great uh to Cave at that it was the shortest uh complete and successful Eva on record I think we got 12 minutes to time on that all right thank you Steve yeah thanks Steve you're [Music] welcome C let me know if you need to slow down for any ears or throttling the I hatch to Norm or towards Norm NASA astronaut Steve Bowen who was serving as today's ground IV or spacewalk Communicator just handed over to NASA astronaut Matt Dominic aboard the International Space Station to continue taking the crew through the repressurization steps before they open the hatch between the crew lock and Equipment lock portion of the quest airlock e e for NASA astronaut Steve Bowen handed over the communications to NASA astronaut Matt Dominic you heard him talking about a 12 minute Eva that Eva took place on June 10th 2009 with Steve Bowen as one of the space Walkers to reconfigure the transfer compartment between the zvezda and zarya modules on the International Space Station it was one of Bowen's uh 10 Total Space walks that he's done the crew lock pressure is now up to 6.7 pounds per square inch and continuing to rise for those of you who are just joining us us spacewalk 90 scheduled to take place today the is good good well us spacewalk 90 scheduled to take place today was terminated due to a water leak in the service and cooling umbilical unit on NASA astronaut Tracy Dyson space suit Dyson and NASA astronaut Mike Barrett had set their suits to internal battery power at 8:46 a.m. eastern 7:46 a.m. Central and had opened the evh hatch before reporting the water issue the crew is now working to repressurize the crew lock section of the quest air lock before returning inside the station's equipment log for today's spacewalk they had planned to complete the removal of a faulty electronics box from a Communications antenna on the starboard truss of the space station and had also intended to collect samples for analysis to better understand the ability of microorganisms to survive and reproduce on the exterior of the orbiting Laboratory good mik yeah I was GNA say TC how you doing with the Press I'm doing good it's a good R okay keep the r yes before we go in and have to help with the UPA or something the crew lock pressure is now up to 8.3 pounds per square inch and continuing to climb we expect that pressure to get up to about 14.7 PSI before they open the hatch between the crew lock and the equipment lock to bring NASA astronauts Tracy Dyson and Mike Barrett back in and begin removing their suits airlock Houston on one for mini big picture all right Matt once we get the IV hatch open uh we'd like for you to perform an inspection uh and give us a verbal report uh taking a look at the suits and your best estimate of quantity of water in the crew lock uh we do understand that some of it some of that may have been lost wi you know uh butcher is looking at the gem window I went to robotics work station I could see icex L on around the space station on almost all the cameras so that should give you a perspective and looking in the air lock it was pretty impressive we was watching a snowstorm use 10 copies uh thanks for that description um once we get a report uh of the crew lock we'd like you to clean up with towels if you have any extra hands available and then going into post DVA procedure obviously you can skip the rfg steps uh we want you to stop prior to step 90 90 for ev1 so this is a SCU step uh that may give us a chance to do some troubleshooting copy for ev2 stop prior to step 90 we go that's for ev1 Houston also the um Sunny had the airlock camera up against the window during the snowstorm if you want to go back in time and look at the tapes it'll give you some idea what it looked like copy uh thanks for that uh and just to clarify Matt step 90 uh hold is for ev1 Sorry Miss speak there Tracy ev1 do not disconnect the seu from the DCM good job we have about having Helping Hands here we have four people all lined up you may be just off camera but we're all lined up ready to pounce copied that's just give you guys a report of what I see in the herlock I see maybe two DRS of water now where I am it's not including my suit it's on the KCK wall I don't think there's a lot in other words C I'm peing at you through the window and not seeing much hou cupies two cups pressurization TC can you repeat we didn't get the unit drop I see only a couple a few drops copy a couple drops the repressurization process of the crew lot continuing to take place the pressure is at 10.8 pounds per square in and continuing to rise up towards that 14.7 PSI mark as teams here in Mission Control Houston continue to look into what exactly happened with the uh service and cooling umbilical unit on NASA astronaut Tracy Dyson space suit they were asking the crew aboard the International Space Station to take some observations and provide some best guesses and estimates of the amount of water that they were seeing inside the crew lock excuse me just got the bat amp High B 5.1 and that's expected expected they want me to report it though in Houston copies cop Houston copied copy my copy B pressure in the crew lck now just under 12 PB per square in as it continues the repressurization process you heard NASA astronaut Tracy Dyson reporting some levels on her spacit battery as a result of the water leak in the service and cooling umbilical of her space suit she has stayed on battery power for the duration of the repressurization process am e the repressurization of the crew lock on the International Space Station is continuing to take place it is now at about 13.2 pounds per square inch as it approaches that 14.7 PSI Mark PSI Mark before they can open the hatches between the crew lock and the equipment lock to bring NASA astronauts Tracy Dyson and Mike Barrett back in and start removing their suits today's space walk was scheduled to take place and to complete the removal of a faulty electronics box known as the radio frequency group from a Communications antenna on the starboard Trust of the space station they were also going to collect samples for analysis to better understand the ability of microorganisms to survive and reproduce on the exterior of the orbiting laboratory the crew had successfully completed all of the pre breath protocols and had moved into the crew lock to depressurize and went all the way to vacuum opened the EV hatch and switched their suits to battery power they switched to battery power at 8:46 a.m. eastern 7:46 a.m. Central shortly after this time they the crew reported a water issue shortly after this report today's spacewalk was officially terminated due to a water leak stemming from the service and cooling umbilical unit on NASA astronaut Tracy Dyson spacit since then the crew has closed the EV hatch and have been working through procedures to repressurize the crew lock before returning inside the station's equipment lock [Music] I he was just turn into a night oh really yeah could you see like where's the station lights lighting up the ice yeah interesting more partly I saw the ter all right well I'm glad you got a view at least least you got that got that RF really wants to stay out there sure I didn't want to say it [Music] the pressure inside the crew lock is now up to just under 14.3 lb per square inch e [Music] [Music] [Music] [Music] want two hatches with the crew lock back up to pressure to match the space station they are now preparing to open the hatch between the crew lock and the equipment lock [Music] d [Music] moving wait till mat put the water switch cards on okay and the the hatch and the hatch is now open at 8:51 a.m. Central 9:51 a.m. eastern all right Houston the hatch is open and I'm just going in there to look for water before I move anybody or anything copy where listening got those water switch get there can you point to where you think you saw water sure don't look at my leg you you you said I could back oh yeah in Sharpie really unive now but there some it's all pretty much evaporated [Music] in that uh hairlock inspection the only drops on Tracy's side of the uh the crew lock um maybe four on the wall or 3 to four millimeters in diameter a small one on her visor but there's very little water I mean there's like nothing four on the wall F copies good [Music] report we're going to go ahead start if with that Pon concurs houst abuse steps four and five of 70-15 [Music] hey Matt we're working step four we'll let the crew know once they no longer hot mik so right now they are still hot [Music] mik they understand they're still hot mic and we're stepping into uh step eight since we don't have any of the rfg stuff that's a good standing after opening the hatch between the equipment lock and the crew lock NASA astronaut Matt Dominic went into the crew lock portion where NASA astronauts Tracy Dyson and Mike Barrett are uh just to inspect the crew lock for any water particles result of the SC message 433 for procedure Deltas 433 433 to inspect for any water particles as a result of the water leak in the service and cooling umbilical unit on Tracy Dyson space suit Matt Dominic and Janette EPS currently on your screen will now work to move Tracy Dyson and Mike Barrett back into the equipment lock after they are back in the equipment lock they will remove the safer or simplified aid for Eva rescue from the back of their space suits they will then begin some steps for suit doing or removal PC and you are no longer hot m e and you can now see NASA astronaut Mike Barrett currently being moved from the crew lock to the equipment lock portion of the International Space Station's Quest airlock e e the safer or simplified aid for Eva rescue has been removed from the back of NASA astronaut Mike Barrett's extra vehicular Mobility unit or emu which is the white space suit that he's currently wearing e you can now see e on understand the messages on board messages on Board number 433 can you give me a step where I need to start looking at that message because I want to keep moving with the crew yeah uh some of them are going to be pretty apparent uh and related to the rfg um so in Step 54 is probably where you see a Delta that's just a stoage step and then uh look closely on the rest of the steps I'm not going to look at that message until I get to step 53 does that work that'll work Matt and yeah I think the only thing we didn't do is we didn't take photographs but there was really nothing significant other than water I can get a picture of a water droplet if you want it we're all set Matt your description was really really helpful and then uh the Savers are getting packaged up Janette and I are going to focus on Mike and TC and after that uh Team Starliner is going to go in there and do your video tour for the IV hatch and the air lock does that work for you guys B work for us thanks both NASA astronauts Mike Barrett and Tracy Dyson have had their sfers or simplified aid for Eva rescue removed from the back of their suits and they're now working through procedures to begin doing or removing their emus want to give you an update on Comm here uh so uh we're having some KU issues on tus 275 uh we're coming up on a 275 pass here pretty soon uh so big picture we're not going to get video down from you uh that's not a constraint uh we could come back up back on board later for the video tour say time for post teers 275 that g&t time we can expect it to be good checking right Matt uh GMT 1434 we're going to be on another satellite 14 34 will kill on your screen you're seeing NASA astronaut Mike Barrett on the left hand side and NASA asant Tracy Dyson on the right hand side in the extra vehicular Mobility units they had dawned those space suits several hours ago and completed pre- Bru protocols moved into the crew lock depressurized the crew lock down to vacuum open the EV hatch and turned their space suits onto battery power shortly after setting their suits to battery power at 8:46 a.m. eastern 7:46 a.m. Central the crew reported a water issue after after some brief troubleshooting on the ground the spacewalk was officially terminated due to this water leak that was resulting from the service and cooling umbilical unit on NASA astronaut Tracy Dyson space suit the service and cooling umbilical is an umbilical that attaches the Emu or extra vehicular Mobility unit to transfer electrical power Hardline Communications oxygen cooling water and feed water between the International Space Station and the Emu or extra vehicular act Mobility unit at no time was the crew in any danger during this water leak but as a result of the termination of the spacewalk the EV hatch was closed and they began the process to repressurize the crew lock bringing it back up to 14.7 pounds per square inch they then opened the hatch between the crew lock and the equipment lock and moved NASA astronauts Mike Barrett and Tracy Dyson back into the equipment lock where they removed their safersit aid for easy VA rescue and have now begun doing or removing their suits we will continue to provide live coverage of the suit doing procedures until their helmets have been removed e e e e e e can now see NASA astronaut Butch Wilmore in the center of your screen he's part of NASA's Bing crew flight test currently on board the International Space Station he is capturing some photos of the glove of NASA astronaut Tracy Dyson's emu or extra vehicular Mobility unit as a result of today's space walk termination they are working to gather some extra imagery to send to teams here on the ground to um investigate and troubleshoot and really determine a cause of the leak in the service and cooling umbilical unit e e e e e e we are now in a Handover between satellites for the tracking and data relay satellite system while we won't have video for approximately 20 minutes expecting to regain it at 9:30 34 a.m. Central we will still have Audio Communications with the crew as they continue to work through steps to do or remove the space suits from NASA astronaut Tracy Dyson and Mike Barrett we have also received word from today's spacewalk officer that today's space walking time was 31 minutes and this is the time from uh switching the suits to internal battery power which took place at 7:46 a.m. Central 8:46 a.m. eastern to the time that the repressurization of the crew lock took place at 8817 a.m. Central 9:17 a.m. eastern with this 31 minutes that brings NASA astronaut Tracy Dyson's space walking time up to 23 hours and 20 minutes across four Evas and for NASA astronaut Mike Barrett that brings him up to 5 hours and 37 minutes of space walking time across three Evas lock Houston on one for deltas hou go ahead us Matt we currently don't have video so we're just going to feed these delt now uh in Step 61 and 63 uh it has you removing the absorbent materials we want you to leave those installed for now uh and when you get to it later leave scus connected and that's for both suits for everybody hey firm for everybody okay we got a lot of Deltas hou over tracking here the first Deltas I see are in 47 to 50 and then uh 61 63 copy good uh that's a good understanding of the Deltas and as a well he's in my xtp does not have a 63 so that's easy not to do and 61 is just taking the helmet absortion pads out so we'll leave those in the helmets no problem yep that's good and uh step 54 for the PGT batteries those could go in the mesh bag so that's the other Delta okay PGT is going to a mesh bag okay we're going to Prior getting these folks out of this sus and then we might have to do later for those things there's a lot of things appreciate it copy no worries all the picks we took today are on ssc6 ssc6 and that includes the glove pictures and the only thing of note was inboard uh right side of uh Tracy's index finger so the inboard side of Tracy's index finger is there anything it might be a question thanks but we'll look at S6 appreciate the words yeah I think I said left hand just to clarify it is the left hand in the inboard side of the left index finger copy left hand we were uh just uh asking about that ourselves we continue to be an loss of signal for the video feeds coming from the International Space Station due to a transfer of ground stations but we still have Audio Communications with the crew on board the station as they continue to work through steps to remove the extra vehicular Mobility units currently on NASA astronuts Tracy Dyson and Mike Barrett following today's 31 minute spacewalk The Space Walk time officially began at 7:46 a.m. Central when they switched their their suits to battery power the crew had opened the hatch of the quest airlock before reporting a water issue this water issue was traced to a water leak in the service and cooling umbilical unit on NASA astronaut Tracy Dyson spacit as a result of this issue us spacewalk 90 for today was terminated the crew then worked with ground controllers to repressurize the crew lock section of the equest air loock before returning inside the station's equipment lock where they are currently working through those steps to remove their space suits for today's spacewalk they had planned to complete the removal of a faulty electronics box known as a radio frequency group from a Communications antenna on the starbridge trust of the space station they were also going to collect some samples for analysis to understand the ability of microorganisms to survive and reproduce on the exterior of the orbiting laboratory the spacewalk was expected to last about 6 and 1 half hours teams here in Mission Control Houston are continuing to troubleshoot and work through steps to better understand the water leak issue that was reported and the crew aboard the International Space Station are also working to collect imagery um of the crew lock and of the space suits to send to teams here on the ground to inspect further while today's space walk was terminated early the crew was at no time in any danger at the time of the spacewalk termination it was unclear how much water was left in the water tanks of her suit which is why the spacewalk was terminated early as a precautionary measure the service in cooling umbilical um on NASA Tracy Dyson suit that was experiencing that water Luke is a an umbilical that transfers electrical power Hardline Communications oxygen cooling water and feed water between the International Space Station and the extra vehicular Mobility unit we will continue to provide live coverage all the way until we receive video views back and we confirm that NASA astronaut Tracy Dyson and Mike Barrett have had their helmets removed we expect to regain video feed here in about 12 minutes at 9:34 a.m. Central 10:34 a.m. eastern e on your screen now you can see flight director Rebecca Wingfield towards the bottom she is the lead flight director for today's spacewalk operations she's currently speaking with flight controllers here in the International Space Station flight control room as they continue to discuss today's space walk and the issues that arose and also work through troubleshooting and next steps e e e e e e we now have confirmation that NASA astronauts Tracy Dyson and Mike Barrett are out of their space suits following today's 31 minute spacewalk us spacewalk 90 was going to complete the removal of a faulty electronics box from a Communications antenna on the starboard truss of the space station they were also planning to collect samples for analysis to better understand the ability of microorganisms to survive and reproduce on the exterior of the orbiting laboratory while the spacewalk was intended to last 6 and 1 half hours it was terminated shortly after the suits were set to battery power at 7:46 a.m. Central 8:46 a.m. eastern the crew had opened the extra vehicular hatch on the quest airlock before reporting a water issue this water issue was traced to a water leak in the service and cooling umbilical unit on NASA astronut Tracy Dyson's spacit at no time was the crew in any danger but they did make the decision to terminate the spacewalk as it was unclear how much water was left in the water tanks of Tracy Dyson's suit the crew then closed the EV hatch and worked with ground controllers to repressurize the crew lock section of the quest airlock before returning in inside the station's equipment lock the crew then work to remove their space suits and they have successfully removed from their extra vehicular Mobility unit or emus to complete today's um spacewalk activities the official duration of today's spacewalk was 31 minutes that brings NASA astronaut Tracy Dyson's Total Space walking time up to 23 hours and 20 minutes across 4 vas and it brings NASA astronut Mike Barrett up to 5 hours ACR team Mission Control Houston will continue to spend the day troubleshooting and collecting imagery and data from the crew aboard the International Space Station to better understand what exactly happened with the service and cooling umbilical unit and the water leak that took place today with that we will conclude our coverage of today's spacewalk activities this is Mission Control Houston [Music] [Music] [Music] [Music] [Music] [Music] [Music] [Music] [Music] e e e e for
