CSPAN Key Capitol Hill Hearings December 24, 2013

Standby just a second, hopper. Ok. It. Will scratch things up and hopper, you may have checked that release ring. Can you verify . For the snap back . Yes. I did not get a good snap that. Copy that, so just stabilizing the qd with one hand holding it so the qd does not demate. Use the blunt end of the bill drive lever, try not to make any contact with the mail qd and see if we can counteract. Spacecraft communicator, mikewheelock instructing hopkins how to use this particular tool to ensure that we have a tight mate of this third in a series of four fluid lines to. The new spare pump module it is staying clear of the button, just to a pull test. I have a pull test. Copy and a visual. I heard you said the visual cap test looked good as well. It does. Is only thing i will say there is a little bit of play where i can push it forward and it comes back. Be 16 of an inch or 1 32 of an inch. There is some play for and after. Four and aft. 1 32 of an inch. There is some play for and after. Four and aft. Standing by. We are getting words that this may be typical. Rick, do you remember when we disconnected that line, was there some play in it . I cannot say i remember, sorry. Ok, copy that. Standby. Copy. Ok, guys, we will take a glove checked from both of you when you are able. Houston, from ed1, the half second as normal on the glove and the index finger, the thread near the end of the digit, there is more of that showing. Dont see any damage underneath. Ok, copy, hopper print thats acceptable. No change. Copy, rick. This is missioni heard you p test looked good as well. It does. Control houston, five hours and 12 minutes into the spacewalk. Three out of four fluid lines are now connected to the new spare pump module. You will be working with the m3 line now. The m3 line is a is the final fluid line that is hooked up to the pump module jumper box. The jumper box is utilized in an interim state to maintain among you flowing through the plumbing of the space station on the starboard truss in an acceptable fashion during the period between the disconnection of the saturday and the installation of the new pump today. There was difficulty with the third in the series of fluid lines, the m4 line. It refused to budge from that jumper a short time ago. When we finally were able to get it disconnected, a small number of ammonia flakes were detected by the crew. Playing it safe and per the flight rules, we will have to conduct a decontamination procedure for the crew before they are able to reenter the International Space station. That is forward work a short time from now. The task at hand now is to disconnect the fourth and final fluid line from the jumper box and hook it up to the new pump module. Can you squeeze the handles and i will pull back on the jumper box . That qdte we have to and i will review the steps when you are ready. Ready. Ready. Lease the side loads prior to demate. Pull back on the release ring and demate the qd. Demated. Demated. Looks pretty clean. On the jumper box copy that. Got it. In the female and, i do see some likes, some snow. The female plug. And the casing. There is a gap there and i can see one snowflake there. If you can see that, houston. Do you have a visual . Ok, yes we do, hopper. And hopper, as you are looking at the female end, can you verified the release ring is retracted and the forward white than does not visible . Im sorry. The release band is retracted. Copy, thank you. Standby for mate of the m3 to the pump module we are going to have to look starboard again. Ok, guys, we have a go to mate m3 to the pump module so get in position as needed for that maneuver. Copy. Ok, do you need me to pull this . Yes, we need to pull it back. Of this fourth line seemed to be no problem. A touch of residual ammonia flaking noted at the end of the connector but the thermal systems officer and the Flight Control team in Mission Control argot to mate this fourth line to the new pump. It is ready to mate and the detemp button should be up. Assess and counteract side loads prior to mate and mate the qd. Copy that. Hold on. Hold on. [no audio] [inaudible] five hours, 17 minutes into the spacewalk, and an hour and a half since the beginning of the of theg and mating fluid lines and onto the new spare pump. Copy forward white band visible. Hopper, on them3, perform snap back test. It release. D. Copy and forward white band visible again . No. It released. The qd just demated. Copy that, we will start from the beginning. Ok. We will just step through again when you guys are ready. Ready. Ok, weve done the inspection again. Verified the female qd is ready to mate and the d10 button should be up. Its stock right now. It does not want to move. It should be depressive all, took thats correct. Its not. Hopper, make sure the bale is full. I push it back and it is now depressing. Button ish,e detemp up and check that the forward white band is not visible. Not visible. Assess and counteract sideload prior to mate and when you guys are ready, made to the qd. Are you ready . Ready. Ok, lets do it. Took thats correct. The clamp is released and out of the way. On the snapback, if we can counteract the we have a good snapback. Hopper. That, stay clear of the button and the release ring. Perform papal test on the qd. Perform pull test on the qd. Completed pull test. Looks good and the visual gap test, did you read that already . I have not. We will take that when you are able. Its not. Houston, i would like to pull this off and tried one more time, if we could. Standby, hopper. Ok. The white band does not seem to be as big its supposed to be. Have a little bit of play in them. The white band what about that gap . Back. L this mli those are the threads. Those gap that gap is the same as f2. I think its good. Ok, hopper, we think you are connected. Back,we had a good snap what you are doing with your left hand, if you want to pull forward on that release ring to see if it moves further forward, up by the release ring at the forward end of the connector. Release ring. The release ring, not the bering just to see if it snaps out anymore. Ok, so here. Band sohe forward white we feel it is not in fit. Thats the bail. I concur. Ok, copy that. I think the gap looks the same as the other ones. Ok, copy that, guys. I heard that that we are getting ready to open m3. Jumper the pump module are here for now. Copy that, rick, thanks. Coming your way. Copy. In selling one final positioning device to find some structural stiffening for the fourth and final fluid line. We have a go to open the m3 valve. It is called the forward spacer after the release ring. Assess and counteract side loads. Copy. Detent buttono and move it forward to the spacer. Against the fourth spacer. Install the aft spid spacer. Thermal systems officer here reports no leakage through any of the four fluid lines now hooked up to the spare pump module. Nice work, guys. And guys, the next step is to finger start the pclamp on the m4 line. Ok, am i clear to release my wrist off the spid . Affirmative. Im ready. About 20 centimeters starboard. Starboard, 20 centimeters. Here comes the 20 centimeter motion to the starboard. Good motion. Good motion. Its about 20 . Stopping motion. Stopping. Destination 10 centimeters. Now in motion. Motion. This is Mission Control, houston all for fluid lines enable ammonia to flowthrough cooling loop a on the starboard side of the International Space station and they are now connected. One of the fluid lines , the so line proved to be a bit stubborn as it was being disconnected by hopkins and modulechio from a pump jumper box that provided an interim home for two of the four fluid lines during the period between the removal of the faulty pump on saturday and the installation of the new pump earlier today. Dirt ime that the that the third in a series of fluid lines was disconnected from the jumper box, some flakes of ammonia were detected emanating from the female module of that interface. The crew was diligent and pressed ahead with a recommendation of the Flight Control and we are able and were able to get that line disconnected and connected backup to the spare pump itself. The thermal systems officer in Mission Control is monitoring pressure in the system and everything looks good so far. We will be pressing ahead for the connection of a series of five electoral connectors that will set the stage for a so called bump test that will be monitored by the thermal systems officer under the call sign of spartan here in Mission Control. That bump test will be a brief but important test of the internal mechanisms in the new pump including all of the valves to make sure that we have a pump that is alive and well or it stow that as needed and retrieved this. The final line. Gather items. Copy, the next step is opening the valve at m4 but standby on that. I need to come port about 20 centimeters. Ok, copy porch, 20 centimeters . Thats affirmative. Ok, here comes the motion. Its in motion. Good motion. Stop motion. Complete. Breaks are on. Breaks are on. Ok, guys, when you are ready, we will open the m4 valve. We are ready. Ok, guys, prior to and movement, moved to the unlock position. Unlocked. Copy. To press the d10 button and push the blae forward so the white then begins to show. Copy. Ok, just beginning to show. Ok, we are going to slide the spid in now. Knob up. Ull the lock slide the slider aft and install the spid. Installed. Slide the spid slider forward to engage on the handle. Copy. Slide the slider aft and install the spid. Its over the handle. Ale towardush the b the closed position for this letter and put the lock knob onto the spid. Will this go all the way up against the release ring . Is that correct . Checking the slider . Yeah. Let me see. Move your left hand. It should go all the way. We are checking. The bale needs to go further forward. I agree. Houston, think about it. We are discussing, standby. [inaudible] i got one. Ok, hopper, we are expecting maybe a little bit of it yet between the forward part of that spacer, the spid and the release ring so if you can confirm it is fully seated in the aft portion and the bale is locked inside the spid, we are in good shape. Standby. And those forward tanks should be engaged as well. Tangs should be engaged as well. Ok, so, on the spid, the af t portion of the spid is back. Probablyrd portion is 1 4 inch space. Config, s a good hopper. Ok. Down around the handle. Copy. We will do a pull test on the spid and i think youve already done that. The spid is in place. Ready for a pull test. Ok, it looks like we have a good valve opening there, guys. Shorthand over, we will meet you on the other side. Copy. [no audio] we went around the wires. Ok guys, we have about 1. 5 to four minute drop out so we wanted to an ammonia inspection in your sues. Try to get an oblique angle. We want you to raise your sun visor, inspect each others suits and take a look at any loss of tmg thread pattern, any or glossy or hardpacked snow appearance on the front of the suits. And any unusual contours, copy . We copy. I am putting something in the bag. I will be right there. Copy that. Since you guys were in a mini blizzard, we will look all over the suit. They were pretty small. Most of them but there were a few up to1 4 of an inch. Copy that, we have about 30 seconds and we will have a four minute drop out and meet you on the other side with the results of your inspection. Things, guys. You bet. Coming your way, mike. An oblique angle. This is Mission Control houston, five hours 39 minutes into todays spacewalk or all four fluid lines have been to be up and confirmed perfectly made it mated between the ammonia system on the trust and the new pump module that was installed earlier today by spacewalkers mike hopkins and rick mastracchi o. During the time the third of the four fluid connection lines d was beingemated from a pump module jumper box to maintain duringte of the ammonia the time they were pretty smal. Between the disconnection and removal of the faulty pump module on saturday, and the new pump earlier today, the third in this series of lies, the socalled m4 line was very stubborn. It was finally disconnected but some some dissipation, flakes of ammonia that the crew believes came in contact with their suits. They are in the process of inspecting one another and beginning decontamination procedures that are part of the normal flight rules that any handling of these ammonia lines in the vacuum of space. Meanwhile, the thermal systems officer, the spartan as he is called in Mission Control, has informed the flight director that with the valves open, 35 pounds of ammonia have flowed from the Ammonia Tank Assembly in an adjacent slot on the starboard truss of the International Space station to the newly installed pump. That is the first step in the ultimate activation of the new pump but there has been a change of plans. To enable the Flight Control team, particularly the thermal ontems, to gather data hydraulic conductivity between the Ammonia Tank Assembly and the pump itself, we will not be doing that bump test that i explained earlier. The brief check out of the valves internal to the new pump itself they will wait until this evening after the system is bypletely pressurized nitrogen that will come from a nitrogen Tank Assembly on the starboard side of the International Space station. That will pressurize the new pump to its full pressure. Willthat, the pump bespun up and the pump will come to light. That will not happen until this evening. Will belly, the cva concluded with the hooking up of electrical connectors as an extent by the crew outside. After which will begin the cleanup steps and the crew will then move inside the quest airlock and repressurized the airlock to complete the spacewalk. All of the examination of the functionality of the new pump will continue throughout the course of the day today and later tonight. The pump will beast bone up the pump will be spun up and checked out by the flight team in Mission Control. We will provide updates through on otherater tonight activities associated with the pump and the final result on the Health Status of the pump itself. Again, the initial bump test to give us a snapshot of the help of the pump of the health of the pump would be determined by the thermal Missions Team here so they can conduct other steps with the pressurization of the new pump itself and the actual activation of the pump that will come later this evening. We dont expect any problems of any of that activity. Its just that we will not get immediate results until later this evening. [no audio] [no audio] [no audio] [no audio] are you with us . Ok, im with you. Go ahead and do a gc8. Im ready. Lets go starboard. 50 centimeters. Starboard, 20 centimeters. Motion. Es the copy. Good motion. Stop motion. Stopping motion. Standby. Complete for now. Breaks are on. Copy that. We are back with you, it looks like you got the wire tie in . We did. Sounds good. Ande twists on the bale around all three lanyards and three twists as well. Thats affirmative. Im looking at m3. Qd. The backside of the where the line goes in. Like is a gap that looks the inner part where it slides into the backside of the qd. Copy, standby. Our telemetry in the system looks real good and tight right now. I dont see any leaking. Confirm that. I dont see any leaking. Partmply looks like the that slides into the hard outer shell of the qd, there is a gap. Its only on one side. Copy that. Cclamp here . Re a phink what i am seeing is a clamp. Ok, copy that, hopper. Since it looks different than the other lines, it looks like the mli is pulled back a little bit, is that correct . It is just a little bit. Now that i look at it from the other side, it is just the band of the pclamp that was released. Ok, we will take the results of the ammonia inspection if you have it. Ev, im looking ev1 to 2, i can see no indications of ammonia on the suit. Same as my, ev2, instructions for him. We will take these as very reliable based on the white suit and the white snowflakes and the angle we are looking at. Copy all that. Hopper, thank you. [no audio] ok, guys, we will start working on the electrical connectors now. Any order so if you want to work the zenith and nadir, work that out between you. Ok, that sounds good. I will go to zenith, rick. Ok. I will try them. I will try and free float. Can i get gca . 20 centimeters zenith . Ok, hopper am a five centimeters. 20 centimeters. Copy, 20 centimeters. In motion. I see good motion. Copy. Thats about 20. And that motion. This is Mission Control, houston, five hours, 50 minutes into todays spacewalk. The two crewmembers are now pressing ahead to mate a handful of electoral connections of electrical connection to the newly installed pump modules. The valves are open and some 35 pounds of ammonia have flowed into the new pump. That will set the stage for of the pumpheckouts module systems throughout the day by the thermal systems officer here in Mission Control but we will not actually get to the pressurization of the pump andugh a nitrogen system actual activation of the pump until this evening. That activity should be complete by about midevening central time. Further updates following the completion of todays spacewalk will be provided through the web , updates on our main page,www. N asa. Gov that will appear on the station website. Basically went by the book all the way through club their procedures today, running into only one snag and that was the disconnection of the third in the series of four fluid as it is m4 line called, from a pump module jumper box from which it had been temporarily attached to maintain the flow of ammonia through the cooling system of the space station in a liquid state from the time that the old pump was disconnected on saturday until the time the new spare was installed earlier today. Exposed to some dissipation of flakes of ammonia from the female side of the Quick Disconnect connection line from thatm4 line so they inspected one another in a loss of signal period and reported no apparent ammonia on each others suits but because of the exposure, the flight rules call for them to maintain a bake out to enable any residual ammonia to dissipate from their suits before they reenter the International Space station later today. All of the early indications suggest that the newly installed pump is in good shape. Issues withve no its pressurization and its activation later today which tol involve the spin up begin exercising all of the valves and the int
