1 00:00:04,760 --> 00:00:03,290 this is Mission Control Houston welcome 2 00:00:06,200 --> 00:00:04,770 to the International Space Station 3 00:00:08,210 --> 00:00:06,210 flight control room again that was a 4 00:00:10,940 --> 00:00:08,220 video replay from a downlink earlier 5 00:00:13,549 --> 00:00:10,950 yesterday from the commander dan burbank 6 00:00:15,650 --> 00:00:13,559 and here with us today we have our very 7 00:00:17,930 --> 00:00:15,660 special guest astronaut Mike Fossum 8 00:00:20,960 --> 00:00:17,940 welcome Mike hey it's great to be back 9 00:00:22,700 --> 00:00:20,970 at me go good and so Mike was is a 10 00:00:24,320 --> 00:00:22,710 veteran of three space wise the most 11 00:00:25,730 --> 00:00:24,330 recent flight was aboard the 12 00:00:28,310 --> 00:00:25,740 International Space Station he was the 13 00:00:30,169 --> 00:00:28,320 commander of expedition 29 he was 14 00:00:32,389 --> 00:00:30,179 actually up there and handed over it as 15 00:00:34,160 --> 00:00:32,399 you heard in the video and then talked 16 00:00:36,530 --> 00:00:34,170 about a little bit about that hand over 17 00:00:39,139 --> 00:00:36,540 and so Mike was actually there when Dan 18 00:00:40,430 --> 00:00:39,149 arrived and had a very quick hand over 19 00:00:42,319 --> 00:00:40,440 it was one of the guys handing over to 20 00:00:43,880 --> 00:00:42,329 him it was great this video was great I 21 00:00:46,310 --> 00:00:43,890 really loved it because it's such a 22 00:00:47,660 --> 00:00:46,320 great description from Dan about what 23 00:00:49,549 --> 00:00:47,670 it's like to live up there to come 24 00:00:51,080 --> 00:00:49,559 aboard and to have a very quick hand 25 00:00:53,720 --> 00:00:51,090 over like you said we really only had 26 00:00:55,459 --> 00:00:53,730 about four days to pass over as much as 27 00:00:58,670 --> 00:00:55,469 we could and show him how things worked 28 00:01:01,130 --> 00:00:58,680 and where we had hidden things and get 29 00:01:02,930 --> 00:01:01,140 ready ourselves to leave and so it's 30 00:01:04,399 --> 00:01:02,940 it's great seeing the video in his whole 31 00:01:06,380 --> 00:01:04,409 description of what it's like to live 32 00:01:08,929 --> 00:01:06,390 and work up there for a long period of 33 00:01:11,090 --> 00:01:08,939 time and kind of looking back now as he 34 00:01:13,460 --> 00:01:11,100 said nearing the last the last few weeks 35 00:01:16,399 --> 00:01:13,470 and getting ready to come home okay so 36 00:01:17,690 --> 00:01:16,409 what so he is now just a little more 37 00:01:20,090 --> 00:01:17,700 than a week and you were there about a 38 00:01:22,249 --> 00:01:20,100 week when he did arrive so talk to me a 39 00:01:23,960 --> 00:01:22,259 little about that last week I mean you 40 00:01:25,730 --> 00:01:23,970 obviously had a little more crew prep 41 00:01:27,350 --> 00:01:25,740 because you had handover activities as 42 00:01:29,600 --> 00:01:27,360 well but talk to me about some of your 43 00:01:31,520 --> 00:01:29,610 thoughts and and whatnot before yes 44 00:01:33,590 --> 00:01:31,530 what's going on right now is really is 45 00:01:36,440 --> 00:01:33,600 it and I've talked to Dan I talked to 46 00:01:38,330 --> 00:01:36,450 him twice last weekend they're getting 47 00:01:41,450 --> 00:01:38,340 ready to mean to come home he sees 48 00:01:44,210 --> 00:01:41,460 starting to pack things up and and you 49 00:01:45,830 --> 00:01:44,220 know and and you know putting those last 50 00:01:47,210 --> 00:01:45,840 few things that he really wanted to do 51 00:01:49,429 --> 00:01:47,220 there at the very top of his own 52 00:01:52,340 --> 00:01:49,439 personal to-do list he's trying to get a 53 00:01:53,600 --> 00:01:52,350 couple of those things done and he said 54 00:01:55,639 --> 00:01:53,610 I know that he's spending a little extra 55 00:01:57,410 --> 00:01:55,649 time with Don and Andre to say okay 56 00:01:59,359 --> 00:01:57,420 let's make sure we're really you know 57 00:02:00,469 --> 00:01:59,369 you guys really know everything that you 58 00:02:02,209 --> 00:02:00,479 need to know and of course they do 59 00:02:04,280 --> 00:02:02,219 they've been there since December also 60 00:02:06,040 --> 00:02:04,290 so they're ready there'll be a little 61 00:02:08,020 --> 00:02:06,050 bit nervous though knowing I 62 00:02:10,180 --> 00:02:08,030 you know how I felt even after spending 63 00:02:13,660 --> 00:02:10,190 months up there as I was taken over from 64 00:02:15,190 --> 00:02:13,670 ron garan but part of its just getting 65 00:02:18,040 --> 00:02:15,200 on getting your things you don't have a 66 00:02:20,110 --> 00:02:18,050 lot of stuff but you really owe it to 67 00:02:22,540 --> 00:02:20,120 the to the people that are following 68 00:02:24,250 --> 00:02:22,550 behind you to take care of your stuff to 69 00:02:26,290 --> 00:02:24,260 get things packed up and to get a lot of 70 00:02:28,300 --> 00:02:26,300 it actually thrown away because we don't 71 00:02:30,220 --> 00:02:28,310 have a way to return clothes or even 72 00:02:32,050 --> 00:02:30,230 wash them so things like clothes or are 73 00:02:34,030 --> 00:02:32,060 actually thrown away when you're done 74 00:02:35,500 --> 00:02:34,040 with them and so those are our pact on 75 00:02:37,000 --> 00:02:35,510 I'm sure a lot of them are packed on 76 00:02:38,770 --> 00:02:37,010 that progress vehicle that's leaving 77 00:02:40,600 --> 00:02:38,780 tomorrow morning they have that thing 78 00:02:42,400 --> 00:02:40,610 packed full of trash right to the point 79 00:02:44,160 --> 00:02:42,410 of just barely being able to operate the 80 00:02:46,090 --> 00:02:44,170 hatch I know how that stuff works 81 00:02:47,590 --> 00:02:46,100 speaking as they just closed those 82 00:02:49,570 --> 00:02:47,600 hatches and they're performing the leak 83 00:02:51,310 --> 00:02:49,580 checks now we'll get into some of that 84 00:02:52,810 --> 00:02:51,320 in a little bit so let's talk about some 85 00:02:54,760 --> 00:02:52,820 of these activities that are taking 86 00:02:56,050 --> 00:02:54,770 place on the International Space Station 87 00:02:57,430 --> 00:02:56,060 I think the last time you not talk there 88 00:02:58,990 --> 00:02:57,440 was a lot going on it seems like there's 89 00:03:00,580 --> 00:02:59,000 a lot going on always a lot going on 90 00:03:03,670 --> 00:03:00,590 that's what I'm beginning to understand 91 00:03:05,400 --> 00:03:03,680 you're so first of all commander Burbank 92 00:03:07,510 --> 00:03:05,410 is working on a remove and replace 93 00:03:09,250 --> 00:03:07,520 replacement of the hydrogen sensor and 94 00:03:10,840 --> 00:03:09,260 this is of the oxygen generator system 95 00:03:13,800 --> 00:03:10,850 can you talk to me a little about this 96 00:03:18,220 --> 00:03:13,810 system takes water and then through a 97 00:03:20,890 --> 00:03:18,230 hydrolysis it splits the water into 98 00:03:22,630 --> 00:03:20,900 hydrogen and oxygen and we have to make 99 00:03:25,449 --> 00:03:22,640 sure that those stay separated and 100 00:03:27,250 --> 00:03:25,459 there's a hydrogen sensor in there that 101 00:03:28,960 --> 00:03:27,260 needs to be replaced periodically and 102 00:03:31,270 --> 00:03:28,970 it's kind of a fussy procedure with a 103 00:03:33,850 --> 00:03:31,280 lot of odd things we don't use very 104 00:03:36,370 --> 00:03:33,860 often something that I'm excited about 105 00:03:38,170 --> 00:03:36,380 today is that the ground has prepared a 106 00:03:40,000 --> 00:03:38,180 training video which is actually 107 00:03:42,520 --> 00:03:40,010 inserted right into the beginning of his 108 00:03:45,820 --> 00:03:42,530 procedures open up a little five-minute 109 00:03:46,720 --> 00:03:45,830 video as refresher training and I think 110 00:03:48,570 --> 00:03:46,730 this is going to be really really 111 00:03:52,420 --> 00:03:48,580 valuable it's going to help us be more 112 00:03:55,000 --> 00:03:52,430 efficient and on orbit to have just this 113 00:03:57,280 --> 00:03:55,010 little video thing similar to today if 114 00:03:59,770 --> 00:03:57,290 you've got to do some work on a car or a 115 00:04:01,600 --> 00:03:59,780 piece of something around the house if 116 00:04:03,699 --> 00:04:01,610 you do in quick internet search you can 117 00:04:06,490 --> 00:04:03,709 find videos on how to do things you 118 00:04:08,979 --> 00:04:06,500 never even been trained on undoing but 119 00:04:10,930 --> 00:04:08,989 you can watch a video see somebody else 120 00:04:12,699 --> 00:04:10,940 doing it then the written procedure 121 00:04:14,620 --> 00:04:12,709 makes sense and you can figure it out 122 00:04:17,620 --> 00:04:14,630 and so that's kind of what we're 123 00:04:19,759 --> 00:04:17,630 evaluating today is dams ability to do 124 00:04:22,550 --> 00:04:19,769 this this 125 00:04:24,890 --> 00:04:22,560 little maintenance activity with the 126 00:04:29,180 --> 00:04:24,900 training that he had a year or maybe 127 00:04:31,100 --> 00:04:29,190 more ago but proceeded the activity with 128 00:04:32,990 --> 00:04:31,110 just a few minutes of video to review it 129 00:04:34,640 --> 00:04:33,000 and I can't wait to hear is a commentary 130 00:04:37,460 --> 00:04:34,650 on that I I watched the video myself 131 00:04:39,649 --> 00:04:37,470 yesterday I did this procedure also on 132 00:04:42,020 --> 00:04:39,659 orbit while I was there did you find it 133 00:04:43,610 --> 00:04:42,030 and i think the videos can be queried I 134 00:04:45,439 --> 00:04:43,620 can't hear I can't wait to hear what the 135 00:04:47,180 --> 00:04:45,449 crew has to say about it that's a great 136 00:04:49,070 --> 00:04:47,190 idea and I can't imagine that that 137 00:04:50,450 --> 00:04:49,080 wouldn't be useful to them so every good 138 00:04:53,089 --> 00:04:50,460 to hear from that now know they have 139 00:04:55,909 --> 00:04:53,099 about three and a half hours schedule of 140 00:04:57,710 --> 00:04:55,919 work time to do that so it does sound 141 00:05:03,770 --> 00:04:57,720 like tedious I bet dance done into an 142 00:05:05,719 --> 00:05:03,780 act so and other things that are going 143 00:05:09,189 --> 00:05:05,729 on pretty exciting stuff Pettit and 144 00:05:12,559 --> 00:05:09,199 Kuiper's are actually working on a 145 00:05:14,839 --> 00:05:12,569 onboard training session with the mainly 146 00:05:16,790 --> 00:05:14,849 a practice session with the robotic arm 147 00:05:19,219 --> 00:05:16,800 they're working with Canada arm to to 148 00:05:21,260 --> 00:05:19,229 grapple the dragon SpaceX's dragon that 149 00:05:22,820 --> 00:05:21,270 set to launch on April thirtieth talk to 150 00:05:24,920 --> 00:05:22,830 me some of them oh yeah this is this 151 00:05:27,830 --> 00:05:24,930 exciting getting ready for that for the 152 00:05:30,920 --> 00:05:27,840 dragon grapple and this is a change in 153 00:05:33,589 --> 00:05:30,930 crew responsibilities because we the 154 00:05:37,580 --> 00:05:33,599 they were planning to catch the the 155 00:05:39,920 --> 00:05:37,590 space exploration cargo vehicle which 156 00:05:41,029 --> 00:05:39,930 has named the dragon was supposed to 157 00:05:44,269 --> 00:05:41,039 arrive a little bit ago it's been 158 00:05:46,370 --> 00:05:44,279 delayed some and so don pettit is 159 00:05:50,240 --> 00:05:46,380 getting will be the prime arm operator 160 00:05:51,769 --> 00:05:50,250 for that we call it a grab just in a way 161 00:05:54,260 --> 00:05:51,779 of talking about it but what happens 162 00:05:57,379 --> 00:05:54,270 here is that dragon vehicle will fly up 163 00:05:59,600 --> 00:05:57,389 and hover right in formation right 164 00:06:02,089 --> 00:05:59,610 underneath the space station just 10 165 00:06:04,159 --> 00:06:02,099 meters out this is really a cool it's a 166 00:06:06,769 --> 00:06:04,169 minute it's a very complicated maneuver 167 00:06:09,709 --> 00:06:06,779 this is a new ship and so this is the 168 00:06:11,240 --> 00:06:09,719 first of a kind and we can do a lot of 169 00:06:12,769 --> 00:06:11,250 simulations and a lot of training on a 170 00:06:15,110 --> 00:06:12,779 lot of things but it really boils down 171 00:06:16,730 --> 00:06:15,120 to the ability of that that dragon 172 00:06:19,700 --> 00:06:16,740 vehicle to maintain a very steady 173 00:06:23,089 --> 00:06:19,710 position and then Don with andre's 174 00:06:25,399 --> 00:06:23,099 assistance will be using the SS rms the 175 00:06:28,700 --> 00:06:25,409 big space station arm built in Canada to 176 00:06:30,590 --> 00:06:28,710 reach out and grab the grapple fixture a 177 00:06:34,370 --> 00:06:30,600 little pin that's on that 178 00:06:36,440 --> 00:06:34,380 on that the spacecraft to and then they 179 00:06:38,030 --> 00:06:36,450 will once they get it on the arm then 180 00:06:40,340 --> 00:06:38,040 they'll feel them and maneuver it and 181 00:06:42,980 --> 00:06:40,350 install it what they're doing today is 182 00:06:45,050 --> 00:06:42,990 actually flying the big arm manual 183 00:06:48,140 --> 00:06:45,060 flying and this is great stuff because 184 00:06:50,180 --> 00:06:48,150 it's it's I mean it's real flying and 185 00:06:52,340 --> 00:06:50,190 there's there's there's there's a target 186 00:06:55,430 --> 00:06:52,350 on the side of the space station and 187 00:06:58,130 --> 00:06:55,440 they're setting the arm up so it's it's 188 00:07:00,650 --> 00:06:58,140 it's not directly over that target it's 189 00:07:03,470 --> 00:07:00,660 at an offset so the crew has to manually 190 00:07:06,710 --> 00:07:03,480 fly the fly the arm to get it centered 191 00:07:09,440 --> 00:07:06,720 up and then fly in / the pin and that's 192 00:07:14,000 --> 00:07:09,450 exactly the kind of maneuver they'll be 193 00:07:17,000 --> 00:07:14,010 doing on about mace mace second or so 194 00:07:19,670 --> 00:07:17,010 when the when the dragon vehicle is up 195 00:07:21,980 --> 00:07:19,680 there ready for the grab and I 196 00:07:24,110 --> 00:07:21,990 understand this is the third time for 197 00:07:26,990 --> 00:07:24,120 the station arm to be used to actually 198 00:07:29,240 --> 00:07:27,000 grapple a free flying spacecraft that's 199 00:07:31,370 --> 00:07:29,250 pretty exciting as well and I understand 200 00:07:33,200 --> 00:07:31,380 now the mission itself of Dragon can you 201 00:07:35,780 --> 00:07:33,210 talk to me about that is basically to 202 00:07:38,660 --> 00:07:35,790 see and to test whether we can fly 203 00:07:40,760 --> 00:07:38,670 commercial small craft up to the energy 204 00:07:43,520 --> 00:07:40,770 presentations this is a big test for the 205 00:07:45,800 --> 00:07:43,530 first two free fliers were Japanese HTV 206 00:07:48,920 --> 00:07:45,810 vehicles and nicole stott and Cady 207 00:07:52,340 --> 00:07:48,930 Coleman were the primum operators for 208 00:07:53,990 --> 00:07:52,350 those two grabs and so this is this is 209 00:07:56,300 --> 00:07:54,000 the third vehicle but it is a different 210 00:07:57,740 --> 00:07:56,310 or it's a third time we do this kind of 211 00:07:59,870 --> 00:07:57,750 operation but it is a different vehicle 212 00:08:02,090 --> 00:07:59,880 so everybody looks forward to just 213 00:08:05,870 --> 00:08:02,100 seeing how how it performs as it gets in 214 00:08:09,410 --> 00:08:05,880 close and now the this is the also the 215 00:08:11,480 --> 00:08:09,420 first of the us-built commercial cargo 216 00:08:13,840 --> 00:08:11,490 vehicles which were built specifically 217 00:08:16,760 --> 00:08:13,850 to bring cargo up to the space station 218 00:08:18,950 --> 00:08:16,770 by a US carrier that's the first time we 219 00:08:24,170 --> 00:08:18,960 have that we have the russian progress 220 00:08:26,150 --> 00:08:24,180 the Japanese HTV and the European a TV 221 00:08:28,070 --> 00:08:26,160 which we have the third of the ATV 222 00:08:30,410 --> 00:08:28,080 vehicles is docked to the station right 223 00:08:33,800 --> 00:08:30,420 now so this is now the next US 224 00:08:35,719 --> 00:08:33,810 capability the SpaceX Dragon and now 225 00:08:38,150 --> 00:08:35,729 hopefully followed soon by the orbital 226 00:08:41,980 --> 00:08:38,160 sickness in a few months also so so talk 227 00:08:45,519 --> 00:08:41,990 to me bring about wise food clothing 228 00:08:47,470 --> 00:08:45,529 medical equipment new experiments those 229 00:08:48,970 --> 00:08:47,480 kind of things I don't have the numbers 230 00:08:50,500 --> 00:08:48,980 on the tip of my tongue but it's over a 231 00:08:53,740 --> 00:08:50,510 thousand pounds of equipment that's 232 00:08:55,750 --> 00:08:53,750 coming up in the on the dragon that's 233 00:08:57,070 --> 00:08:55,760 great well and so it is in points that 234 00:08:58,570 --> 00:08:57,080 that's what I was going to ask uses to 235 00:09:00,160 --> 00:08:58,580 describe the importance of that and 236 00:09:01,990 --> 00:09:00,170 obviously the critical point you know we 237 00:09:04,630 --> 00:09:02,000 have different ways of getting cargo up 238 00:09:06,370 --> 00:09:04,640 there but we we need to get this this 239 00:09:08,019 --> 00:09:06,380 next capability online and it's been a 240 00:09:11,050 --> 00:09:08,029 real challenge for the private companies 241 00:09:12,820 --> 00:09:11,060 that have have you know have been very 242 00:09:16,780 --> 00:09:12,830 anxious to get into this business and 243 00:09:19,090 --> 00:09:16,790 with NASA's support and an encouragement 244 00:09:21,280 --> 00:09:19,100 and and financial incentives these 245 00:09:22,570 --> 00:09:21,290 companies are coming into the into the 246 00:09:24,280 --> 00:09:22,580 business into the game and they're 247 00:09:26,290 --> 00:09:24,290 they're ready that we've had the Flight 248 00:09:28,630 --> 00:09:26,300 Readiness reviews earlier this week and 249 00:09:31,030 --> 00:09:28,640 it's a you know it's exciting times as 250 00:09:33,639 --> 00:09:31,040 we're moving forward to this okay well 251 00:09:35,410 --> 00:09:33,649 we're all excited and looking forward to 252 00:09:37,240 --> 00:09:35,420 that so I'm also while we're talking 253 00:09:38,800 --> 00:09:37,250 about the coming of a vehicle let's talk 254 00:09:40,990 --> 00:09:38,810 about the going of a vehicle so we also 255 00:09:43,690 --> 00:09:41,000 have a spacecraft progress 46 p you 256 00:09:47,110 --> 00:09:43,700 mentioned earlier filled up with trash 257 00:09:48,670 --> 00:09:47,120 till it's about to buckle they have 258 00:09:51,220 --> 00:09:48,680 closed the hatches and they are 259 00:09:53,530 --> 00:09:51,230 performing delete checks and that is to 260 00:09:55,750 --> 00:09:53,540 perform the leak checks escape laura and 261 00:09:57,610 --> 00:09:55,760 kononenko and explain a little about 262 00:10:00,160 --> 00:09:57,620 what they are doing those final closeout 263 00:10:02,800 --> 00:10:00,170 activities well it the first of all you 264 00:10:04,630 --> 00:10:02,810 need to pack the thing up and and and 265 00:10:07,420 --> 00:10:04,640 when you're doing that also maintaining 266 00:10:09,970 --> 00:10:07,430 the proper distribution of the of the 267 00:10:12,040 --> 00:10:09,980 stuff in under the mass to or the center 268 00:10:14,530 --> 00:10:12,050 of gravity because it needs to fly as a 269 00:10:16,630 --> 00:10:14,540 free flying vehicle it doesn't land but 270 00:10:19,090 --> 00:10:16,640 it needs to fly safely and so it needs 271 00:10:22,090 --> 00:10:19,100 to be packed so that the control system 272 00:10:24,910 --> 00:10:22,100 knows how to handle it when would bring 273 00:10:26,710 --> 00:10:24,920 the supplies up to space you know 274 00:10:28,980 --> 00:10:26,720 everybody thinks in terms of getting all 275 00:10:31,840 --> 00:10:28,990 of this food up there and and 276 00:10:33,910 --> 00:10:31,850 experiments and clothes and other things 277 00:10:37,090 --> 00:10:33,920 that you use you have to get rid of 278 00:10:40,180 --> 00:10:37,100 those things too and indeed I mean that 279 00:10:42,420 --> 00:10:40,190 our storage our ability to store more 280 00:10:45,280 --> 00:10:42,430 stuff on the space station is limited 281 00:10:47,290 --> 00:10:45,290 because you reach the point it's kind of 282 00:10:50,230 --> 00:10:47,300 like that garage that's over packed and 283 00:10:52,480 --> 00:10:50,240 multi layers deep so you can't find the 284 00:10:54,780 --> 00:10:52,490 thing you're looking for when it's time 285 00:10:57,120 --> 00:10:54,790 to go find that spare part to do or 286 00:10:58,650 --> 00:10:57,130 error or do some work or even find the 287 00:11:00,720 --> 00:10:58,660 food containers that you're supposed to 288 00:11:03,090 --> 00:11:00,730 be opening up next and so we have to get 289 00:11:04,410 --> 00:11:03,100 rid of stuff and the different vehicles 290 00:11:06,810 --> 00:11:04,420 that are going home now like the 291 00:11:09,060 --> 00:11:06,820 progress we say going home of course it 292 00:11:11,250 --> 00:11:09,070 just burns out right but as well as 293 00:11:13,770 --> 00:11:11,260 human waste and and other things they're 294 00:11:15,840 --> 00:11:13,780 all packed in there okay so it's it's 295 00:11:17,160 --> 00:11:15,850 ready to go and it's the crew really 296 00:11:18,780 --> 00:11:17,170 likes packing those things up because 297 00:11:20,700 --> 00:11:18,790 that means you're opening up some free 298 00:11:22,620 --> 00:11:20,710 space i'm born from what come on boy and 299 00:11:24,120 --> 00:11:22,630 so that's the packing part the other 300 00:11:26,250 --> 00:11:24,130 part they're doing right now is making 301 00:11:29,190 --> 00:11:26,260 sure when that vehicle leaves right now 302 00:11:32,550 --> 00:11:29,200 it's attached to a docking port on the 303 00:11:34,950 --> 00:11:32,560 station that has a hatch and and they're 304 00:11:36,770 --> 00:11:34,960 closing the hatch on the cargo ship as 305 00:11:39,870 --> 00:11:36,780 well as the hatch on the station side 306 00:11:42,900 --> 00:11:39,880 because when when the vehicle leaves 307 00:11:44,670 --> 00:11:42,910 that hatch and the seals on that hatch 308 00:11:48,030 --> 00:11:44,680 are now what's keeping the air in the 309 00:11:50,100 --> 00:11:48,040 station and so we do very carefully do 310 00:11:52,770 --> 00:11:50,110 these checks on that interface to make 311 00:11:56,580 --> 00:11:52,780 sure that the hatch on the station side 312 00:11:58,410 --> 00:11:56,590 is is solid and not leaking sure that 313 00:12:00,090 --> 00:11:58,420 all you exposed to space until the next 314 00:12:02,160 --> 00:12:00,100 cargo ship comes to dock in that 315 00:12:03,960 --> 00:12:02,170 location yes so very important work that 316 00:12:05,520 --> 00:12:03,970 they were working on so it sounds like 317 00:12:09,360 --> 00:12:05,530 we just have nothing but important work 318 00:12:11,790 --> 00:12:09,370 up there so let's talk now about there's 319 00:12:13,860 --> 00:12:11,800 also today club and even Asian are 320 00:12:15,570 --> 00:12:13,870 working while Burbank continues to work 321 00:12:18,930 --> 00:12:15,580 on that hydrogen sensor they were going 322 00:12:20,850 --> 00:12:18,940 to be doing some crew departure pipe 323 00:12:22,590 --> 00:12:20,860 work and you talked a little about that 324 00:12:23,880 --> 00:12:22,600 but there let's talk about something you 325 00:12:28,350 --> 00:12:23,890 did not talk about and that was the 326 00:12:29,820 --> 00:12:28,360 center fit check that is the anti G sing 327 00:12:31,590 --> 00:12:29,830 again I think a Venetian is going to be 328 00:12:33,030 --> 00:12:31,600 doing a fit check of that suit today and 329 00:12:35,070 --> 00:12:33,040 talk to me a little about what that is 330 00:12:37,200 --> 00:12:35,080 well in addition to getting your 331 00:12:38,640 --> 00:12:37,210 personal stuff taken care of and part of 332 00:12:41,520 --> 00:12:38,650 it is making sure you're ready to ride 333 00:12:45,510 --> 00:12:41,530 in the Soyuz spaceship again and the the 334 00:12:48,810 --> 00:12:45,520 anti G suit that that we have in the in 335 00:12:50,850 --> 00:12:48,820 them for high performance jet flying and 336 00:12:53,610 --> 00:12:50,860 stuff here we wear what we've just 337 00:12:55,710 --> 00:12:53,620 called the G suit and it's it it's there 338 00:12:58,890 --> 00:12:55,720 there are it's it's kind of like leggins 339 00:13:00,210 --> 00:12:58,900 that that or pants that have air 340 00:13:01,830 --> 00:13:00,220 bladders inside of them and that's 341 00:13:05,220 --> 00:13:01,840 hooked into the jet so when you're 342 00:13:07,710 --> 00:13:05,230 pulling geez that inflates to keep the 343 00:13:09,010 --> 00:13:07,720 blood from pooling in your legs and and 344 00:13:12,340 --> 00:13:09,020 causing you to lose 345 00:13:15,520 --> 00:13:12,350 sciousness we don't use a similar system 346 00:13:18,400 --> 00:13:15,530 we don't use a system with air inflation 347 00:13:20,980 --> 00:13:18,410 for this Russian space suit we use 348 00:13:23,650 --> 00:13:20,990 something that is you actually uses 349 00:13:27,960 --> 00:13:23,660 elastic and they call it the contar and 350 00:13:31,810 --> 00:13:27,970 that you pull it on and it's very tight 351 00:13:35,020 --> 00:13:31,820 and it squeezes particularly the legs 352 00:13:36,730 --> 00:13:35,030 and the leg muscle area is to keep just 353 00:13:40,120 --> 00:13:36,740 to keep those blood vessels from 354 00:13:42,120 --> 00:13:40,130 dilating and after we land and you try 355 00:13:45,520 --> 00:13:42,130 to stand up to climb out of the ship 356 00:13:47,830 --> 00:13:45,530 after your of your body systems right 357 00:13:49,660 --> 00:13:47,840 now is are working to keep the blood 358 00:13:52,420 --> 00:13:49,670 from pooling in the lower parts of our 359 00:13:54,880 --> 00:13:52,430 of our bodies and there's a system of 360 00:13:56,620 --> 00:13:54,890 different check valves in the veins and 361 00:13:59,860 --> 00:13:56,630 the legs and things like that that help 362 00:14:02,770 --> 00:13:59,870 help that as well as just muscle tone in 363 00:14:05,170 --> 00:14:02,780 space those systems get lazy and so you 364 00:14:06,760 --> 00:14:05,180 need to make sure that that you give a 365 00:14:09,580 --> 00:14:06,770 little extra support it's kind of like 366 00:14:11,650 --> 00:14:09,590 support hose actually or something you 367 00:14:14,890 --> 00:14:11,660 might use for for somebody that has 368 00:14:17,620 --> 00:14:14,900 varicose veins to have to help to 369 00:14:20,670 --> 00:14:17,630 squeeze on the extremities the ankles 370 00:14:24,340 --> 00:14:20,680 lower legs to keep those veins from from 371 00:14:26,500 --> 00:14:24,350 expanding so what they're doing today is 372 00:14:29,680 --> 00:14:26,510 a full check of the full system for the 373 00:14:32,890 --> 00:14:29,690 guys putting on that anti-g kind of 374 00:14:34,510 --> 00:14:32,900 elastic g-suit as well as then the 375 00:14:35,740 --> 00:14:34,520 spacesuit and maybe even getting into 376 00:14:38,920 --> 00:14:35,750 the seats and making sure that 377 00:14:42,280 --> 00:14:38,930 everything fits and and that's it's a 378 00:14:44,590 --> 00:14:42,290 it's part of getting kind of ready to 379 00:14:46,840 --> 00:14:44,600 get in change modes because they've been 380 00:14:48,640 --> 00:14:46,850 you know they've been a space station 381 00:14:50,620 --> 00:14:48,650 crew they've been living up there for 382 00:14:52,690 --> 00:14:50,630 five and a half months and they've been 383 00:14:55,600 --> 00:14:52,700 taking care of the space station and 384 00:14:56,800 --> 00:14:55,610 doing science experiments and it's time 385 00:14:58,660 --> 00:14:56,810 to start changing their way of thinking 386 00:15:00,160 --> 00:14:58,670 it's time to start they're going to be 387 00:15:03,390 --> 00:15:00,170 coming home in another spaceship they 388 00:15:05,470 --> 00:15:03,400 have not spent much time in the Soyuz 389 00:15:07,120 --> 00:15:05,480 practicing those procedures that we 390 00:15:09,730 --> 00:15:07,130 spend so much time before launch 391 00:15:11,680 --> 00:15:09,740 practicing and drilling and and being 392 00:15:14,620 --> 00:15:11,690 evaluated and so now it's it's part of 393 00:15:16,330 --> 00:15:14,630 the whole picture every day get doing a 394 00:15:18,880 --> 00:15:16,340 little bit of that kind of work to 395 00:15:22,180 --> 00:15:18,890 prepare for they ride home and what a 396

00:15:45,140 my russian not there yet so let's go 405 00:15:49,150 --> 00:15:46,520 ahead and ask some questions we have 406 00:15:50,410 --> 00:15:49,160 asked polled twitter and we got some 407 00:15:51,790 --> 00:15:50,420 questions from the public and we have a 408 00:15:54,700 --> 00:15:51,800 few questions so thank you very much for 409 00:15:57,070 --> 00:15:54,710 sending those to us first we'll ask this 410 00:16:00,600 --> 00:15:57,080 the first question comes from Katie Huth 411 00:16:03,280 --> 00:16:00,610 Jones my question did you see something 412 00:16:05,260 --> 00:16:03,290 spectacular from the cupola that you are 413 00:16:06,790 --> 00:16:05,270 unable to capture with your camera first 414 00:16:08,050 --> 00:16:06,800 let's talk about what the cupola is and 415 00:16:09,550 --> 00:16:08,060 then we can answer that question well 416 00:16:11,320 --> 00:16:09,560 first I want to say hi to katie she's a 417 00:16:13,630 --> 00:16:11,330 very old friend and yours was the first 418 00:16:15,790 --> 00:16:13,640 question that popped up so this this 419 00:16:17,890 --> 00:16:15,800 will be fun and I'm glad to answer your 420 00:16:19,990 --> 00:16:17,900 question the cupola is the little 421 00:16:22,960 --> 00:16:20,000 cluster of windows sits on the bottom of 422 00:16:25,660 --> 00:16:22,970 the station and it is spectacular it is 423 00:16:27,550 --> 00:16:25,670 such an amazing part of the station the 424 00:16:30,550 --> 00:16:27,560 other windows that we have are pretty 425 00:16:33,850 --> 00:16:30,560 much you know flush with the with the 426 00:16:35,710 --> 00:16:33,860 outer walls and most of them point down 427 00:16:38,380 --> 00:16:35,720 toward the earth which is really cool 428 00:16:41,440 --> 00:16:38,390 but you don't get a good chance to see 429 00:16:43,210 --> 00:16:41,450 the horizon and with this little cluster 430 00:16:44,950 --> 00:16:43,220 of windows there's one large one that 431 00:16:46,900 --> 00:16:44,960 looks down but there's six that look 432 00:16:51,100 --> 00:16:46,910 around the sides too so you can see the 433 00:16:53,170 --> 00:16:51,110 horizon and for me now I love to try to 434 00:16:55,210 --> 00:16:53,180 capture these these views in the low 435 00:16:57,490 --> 00:16:55,220 light photography of the Aurora and city 436 00:16:59,770 --> 00:16:57,500 lights and stuff were a real challenge 437 00:17:01,990 --> 00:16:59,780 and I enjoy doing that something that I 438 00:17:04,990 --> 00:17:02,000 kept trying to get and I could never get 439 00:17:07,540 --> 00:17:05,000 it right was to really try to capture 440 00:17:10,090 --> 00:17:07,550 the sunrise because it was just so cool 441 00:17:12,179 --> 00:17:10,100 as you're coming across it at night and 442 00:17:15,329 --> 00:17:12,189 seeing the city's rolling by down below 443 00:17:18,280 --> 00:17:15,339 occasionally shooting stars down below 444 00:17:19,840 --> 00:17:18,290 and and then to see the light as it 445 00:17:22,630 --> 00:17:19,850 starts to grow in the horizon as you're 446 00:17:25,449 --> 00:17:22,640 coming toward the sunrise and and and 447 00:17:27,640 --> 00:17:25,459 that light spreads you know across your 448 00:17:29,350 --> 00:17:27,650 view across the horizon and you get the 449 00:17:31,540 --> 00:17:29,360 layers of the atmosphere is the lights 450 00:17:33,160 --> 00:17:31,550 kind of bending through and you can see 451 00:17:34,010 --> 00:17:33,170 these layers and the colors that grow 452 00:17:36,050 --> 00:17:34,020 and grow 453 00:17:38,570 --> 00:17:36,060 and you know it's just a really cool 454 00:17:41,090 --> 00:17:38,580 thing and I couldn't capture that with 455 00:17:42,590 --> 00:17:41,100 the cameras because the extreme lighting 456 00:17:44,870 --> 00:17:42,600 was just too much for it and so I 457 00:17:46,970 --> 00:17:44,880 couldn't get that the really good bands 458 00:17:50,120 --> 00:17:46,980 of color in the atmosphere as well as 459 00:17:52,310 --> 00:17:50,130 kind of the Purple's of the earth and 460 00:17:53,930 --> 00:17:52,320 the as it's starting to be illuminated 461 00:17:57,200 --> 00:17:53,940 down below it sounds like a very 462 00:17:58,880 --> 00:17:57,210 brilliant scene to see and despite the 463 00:18:02,060 --> 00:17:58,890 fact that how many sunrises do you come 464 00:18:04,070 --> 00:18:02,070 across 16 a day and how many you have a 465 00:18:06,740 --> 00:18:04,080 lot of seven days Iran's you have a lot 466 00:18:09,980 --> 00:18:06,750 of opportunities but just hard to catch 467 00:18:12,890 --> 00:18:09,990 hard to capture that kind of thing it 468 00:18:16,460 --> 00:18:12,900 can be done though and and if the guys 469 00:18:18,380 --> 00:18:16,470 up there Dan and Dan Burbank and Don 470 00:18:20,780 --> 00:18:18,390 Pettit and Andre to have been working 471 00:18:22,070 --> 00:18:20,790 hard at catching some of those things so 472 00:18:23,600 --> 00:18:22,080 there's there's some really nice shots 473 00:18:27,200 --> 00:18:23,610 up there okay sounds like you need to 474 00:18:29,270 --> 00:18:27,210 know the trip oh maybe so okay well 475 00:18:32,300 --> 00:18:29,280 speaking of the buoyancy of some of the 476 00:18:35,330 --> 00:18:32,310 sites awarded ISS the second question on 477 00:18:37,340 --> 00:18:35,340 Twitter comes to us from seb and do you 478 00:18:40,480 --> 00:18:37,350 see the city lights as bright as they're 479 00:18:43,460 --> 00:18:40,490 shown on the ISS night timelapse videos 480 00:18:45,380 --> 00:18:43,470 you do the city lights really show up 481 00:18:46,900 --> 00:18:45,390 like that I love to actually had two 482 00:18:48,770 --> 00:18:46,910 pairs of binoculars in the cupola 483 00:18:52,070 --> 00:18:48,780 because you could see the city lights 484 00:18:53,780 --> 00:18:52,080 and it was really cool and I discovered 485 00:18:56,720 --> 00:18:53,790 just with binoculars with a little bit 486 00:18:58,610 --> 00:18:56,730 of a magnification like that you can see 487 00:19:00,200 --> 00:18:58,620 so many details that really jump out 488 00:19:02,720 --> 00:19:00,210 because you have the darker countryside 489 00:19:04,880 --> 00:19:02,730 and then you see these these lights and 490 00:19:07,970 --> 00:19:04,890 you can you know literally see 491 00:19:09,410 --> 00:19:07,980 individual cars on roads out there as 492 00:19:11,600 --> 00:19:09,420 you realize what you're looking at is 493 00:19:16,820 --> 00:19:11,610 the little Bhima headlights or streams 494 00:19:18,650 --> 00:19:16,830 of cars and it so cities and and to see 495 00:19:20,000 --> 00:19:18,660 the bridges to see the rivers that come 496 00:19:22,190 --> 00:19:20,010 through the city with the bridges across 497 00:19:24,770 --> 00:19:22,200 them all those things really jump out 498 00:19:26,120 --> 00:19:24,780 and just amazing to see well that was a 499 00:19:28,430 --> 00:19:26,130 great question because I know that you 500 00:19:29,990 --> 00:19:28,440 sent us a lot of those videos we so we 501 00:19:31,850 --> 00:19:30,000 had a lot of those time-lapse videos and 502 00:19:35,570 --> 00:19:31,860 to me personally it looks sort of like 503 00:19:37,250 --> 00:19:35,580 glitter you know I love ya because you 504 00:19:40,160 --> 00:19:37,260 look at these things and you say how can 505 00:19:42,260 --> 00:19:40,170 I how could I describe this I'm an 506 00:19:44,840 --> 00:19:42,270 engineer yeah I don't have the words to 507 00:19:47,150 --> 00:19:44,850 describe what this looks like and 508 00:19:49,760 --> 00:19:47,160 have to now you can see it you can see 509 00:19:52,190 --> 00:19:49,770 it as we see it and it's sped up when we 510 00:19:54,800 --> 00:19:52,200 take those individual photos and string 511 00:19:57,770 --> 00:19:54,810 them together to make make you know a 512 00:19:59,510 --> 00:19:57,780 video it's we're moving faster in the 513 00:20:01,760 --> 00:19:59,520 video then we're really moving but you 514 00:20:04,430 --> 00:20:01,770 can see it and get that same feeling we 515 00:20:06,170 --> 00:20:04,440 have sure and so thank you to the public 516 00:20:11,510 --> 00:20:06,180 for those questions we have one final 517 00:20:14,240 --> 00:20:11,520 questions here I'm curious as well okay 518 00:20:16,370 --> 00:20:14,250 so this comes from auto Chen hi Mike one 519 00:20:20,320 --> 00:20:16,380 question that concerns me how does it 520 00:20:25,520 --> 00:20:20,330 smell in the ISS thank you for answering 521 00:20:27,770 --> 00:20:25,530 it is a unique smell and it you don't 522 00:20:29,780 --> 00:20:27,780 notice it after you've been there but 523 00:20:33,530 --> 00:20:29,790 when you first get there you definitely 524 00:20:36,740 --> 00:20:33,540 notice it and interestingly I I was able 525 00:20:39,260 --> 00:20:36,750 to bring home a shirt was able to bring 526 00:20:41,300 --> 00:20:39,270 home in my allotment of personal things 527 00:20:46,520 --> 00:20:41,310 I could bring back it came back in a in 528 00:20:48,770 --> 00:20:46,530 a plastic wrap and and and when I opened 529 00:20:51,260 --> 00:20:48,780 that back up it had nobody else had 530 00:20:53,240 --> 00:20:51,270 opened it and there's the smell of space 531 00:20:56,360 --> 00:20:53,250 station to me it smells like a 532 00:21:01,670 --> 00:20:56,370 combination of kind of exotic foods and 533 00:21:03,560 --> 00:21:01,680 spices in a locker room interesting in a 534 00:21:05,330 --> 00:21:03,570 good description well here you know 535 00:21:07,670 --> 00:21:05,340 you're living and working up there for a 536 00:21:09,350 --> 00:21:07,680 period of time and so that's uh I can 537 00:21:11,000 --> 00:21:09,360 imagine so there's also a jam aboard 538 00:21:12,770 --> 00:21:11,010 there is a triple board what you're 539 00:21:16,910 --> 00:21:12,780 using almost every day that's exactly 540 00:21:18,680 --> 00:21:16,920 right yay so so let's get back to space 541 00:21:20,870 --> 00:21:18,690 station I think we let's see if we can 542 00:21:23,210 --> 00:21:20,880 get some video that's that's coming down 543 00:21:25,550 --> 00:21:23,220 to us now the other one of the other 544 00:21:28,610 --> 00:21:25,560 activities that is taking place right 545 00:21:30,260 --> 00:21:28,620 now is Don Pettit is working with 546 00:21:33,050 --> 00:21:30,270 Robonaut and you spent some time with 547 00:21:35,450 --> 00:21:33,060 over not oh you bet so he spent some 548 00:21:36,920 --> 00:21:35,460 time assembling and putting Roca not 549 00:21:39,170 --> 00:21:36,930 together and we're getting a lot live 550 00:21:40,970 --> 00:21:39,180 you right now that is a bore this space 551 00:21:43,160 --> 00:21:40,980 station yeah today is that like a hand 552 00:21:44,720 --> 00:21:43,170 dexterity exercise is a part of what's 553 00:21:47,780 --> 00:21:44,730 going on Robonaut it's a really cool 554 00:21:50,090 --> 00:21:47,790 experiment the first humanoid robot you 555 00:21:52,070 --> 00:21:50,100 know in space and so it's it's really 556 00:21:55,100 --> 00:21:52,080 fascinating now I will tell you he has 557 00:21:57,710 --> 00:21:55,110 freaky long arms 558 00:21:59,900 --> 00:21:57,720 when he stretches out like that to see 559 00:22:02,299 --> 00:21:59,910 his arm then we cut you know he's a 560 00:22:04,460 --> 00:22:02,309 wingspan his arms are I'm guessing 561 00:22:06,620 --> 00:22:04,470 twenty percent longer than you know the 562 00:22:09,169 --> 00:22:06,630 normal if for you know for you know 563 00:22:11,930 --> 00:22:09,179 humanoid torso and head that size these 564 00:22:14,299 --> 00:22:11,940 arms are really long and the fingers are 565 00:22:16,580 --> 00:22:14,309 extra long too but it's it's really 566 00:22:20,960 --> 00:22:16,590 fascinating to see you know and actually 567 00:22:23,090 --> 00:22:20,970 the kind of coordination that does exist 568 00:22:25,039 --> 00:22:23,100 in there and there there's four sensors 569 00:22:27,680 --> 00:22:25,049 built into his hand which allows him to 570 00:22:30,409 --> 00:22:27,690 actually reach out and take your hand 571 00:22:32,270 --> 00:22:30,419 and shake it without crushing it because 572 00:22:34,130 --> 00:22:32,280 he has a strength the question shake I 573 00:22:36,770 --> 00:22:34,140 would you bet it is and so are you ever 574 00:22:39,620 --> 00:22:36,780 intimidated by the handshake is you did 575 00:22:41,419 --> 00:22:39,630 do it I didn't get the handshake it 576 00:22:43,310 --> 00:22:41,429 didn't oh no that's why it was it was 577 00:22:44,780 --> 00:22:43,320 cut short it was cut short a little bit 578 00:22:46,310 --> 00:22:44,790 they were still I mean that we're 579 00:22:48,919 --> 00:22:46,320 learning and that's the why we're sent 580 00:22:51,590 --> 00:22:48,929 him that the only time I was surprised 581 00:22:53,330 --> 00:22:51,600 was there was a some motion that was a 582 00:22:55,490 --> 00:22:53,340 it was bigger motion than I was 583 00:22:57,530 --> 00:22:55,500 expecting and I hadn't cleared enough 584 00:23:01,880 --> 00:22:57,540 room for this big guy to start sweeping 585 00:23:03,320 --> 00:23:01,890 his arms around so I and fortunately it 586 00:23:06,560 --> 00:23:03,330 just it startled me a little bit 587 00:23:09,080 --> 00:23:06,570 everything was fine but before before we 588 00:23:10,220 --> 00:23:09,090 let him out to to play anymore we we 589 00:23:12,049 --> 00:23:10,230 made sure we cleaned up all the 590 00:23:13,850 --> 00:23:12,059 computers and cables and things that 591 00:23:16,220 --> 00:23:13,860 might be within his field to reach right 592 00:23:20,270 --> 00:23:16,230 well aside from fun Robonaut I know has 593 00:23:22,159 --> 00:23:20,280 some very important task and and he it 594 00:23:23,690 --> 00:23:22,169 is up there for a specific reason you 595 00:23:27,020 --> 00:23:23,700 want to talk to you well you know right 596 00:23:29,060 --> 00:23:27,030 now we're there we have found their 597 00:23:32,030 --> 00:23:29,070 there are a lot of things to learn about 598 00:23:34,130 --> 00:23:32,040 how the robot actually moves and works 599 00:23:37,310 --> 00:23:34,140 in the zero-g environment we have 600 00:23:39,860 --> 00:23:37,320 actually was kind of unexpected because 601 00:23:41,409 --> 00:23:39,870 as the initial build up as we're 602 00:23:44,060 --> 00:23:41,419 learning how to do these kind of things 603 00:23:47,900 --> 00:23:44,070 he was you know the plan was for him to 604 00:23:50,360 --> 00:23:47,910 do you know pre-planned kinds of 605 00:23:53,210 --> 00:23:50,370 activities and stuff that had been done 606 00:23:56,200 --> 00:23:53,220 on the ground but we find that the 607 00:23:59,299 --> 00:23:56,210 dynamics of the motion in zero gravity 608 00:24:01,789 --> 00:23:59,309 the joints and stuff don't have the same 609 00:24:03,620 --> 00:24:01,799 kind of resistance or drag and so 610 00:24:05,570 --> 00:24:03,630 there's a like I think of it as like a 611 00:24:07,880 --> 00:24:05,580 bouncing when he goes to move his arm 612 00:24:08,730 --> 00:24:07,890 there would be a little bit of a bounce 613 00:24:11,160 --> 00:24:08,740 to it because 614 00:24:14,220 --> 00:24:11,170 he wasn't you know kind of dampening out 615 00:24:18,570 --> 00:24:14,230 or holding the arm down and that caused 616 00:24:20,520 --> 00:24:18,580 it caused it to trip and so we had to we 617 00:24:23,430 --> 00:24:20,530 learned about the dynamics of the motion 618 00:24:25,260 --> 00:24:23,440 and controlling that motion and so 619 00:24:27,299 --> 00:24:25,270 they've been reprogramming and tweaking 620 00:24:29,010 --> 00:24:27,309 and refining you know those models that 621 00:24:30,630 --> 00:24:29,020 make him work a little bit better and so 622 00:24:33,360 --> 00:24:30,640 it's been a learning process it's been 623 00:24:36,150 --> 00:24:33,370 wonderful the things you cannot learn on 624 00:24:37,950 --> 00:24:36,160 the ground that they kind of expected 625 00:24:39,870 --> 00:24:37,960 these things to go you know go ripping 626 00:24:41,580 --> 00:24:39,880 right through those kind of checks and 627 00:24:44,160 --> 00:24:41,590 you know and on to bigger and better 628 00:24:46,560 --> 00:24:44,170 things but hey that's why you do this 629 00:24:48,150 --> 00:24:46,570 kind of testing and so you know and it's 630 00:24:49,380 --> 00:24:48,160 it's a build-up approach to go through 631 00:24:51,720 --> 00:24:49,390 those kind of things to learn the 632 00:24:56,280 --> 00:24:51,730 control and then to work our way into 633 00:24:58,680 --> 00:24:56,290 doing things like a few weeks ago I did 634 00:25:03,330 --> 00:24:58,690 the first what you would call useful 635 00:25:07,350 --> 00:25:03,340 work where he's moving a a velocity 636 00:25:09,150 --> 00:25:07,360 detector in front of an air air vent and 637 00:25:12,990 --> 00:25:09,160 that's something we do the crew does 638 00:25:15,690 --> 00:25:13,000 periodically and it's to measure when 639 00:25:18,120 --> 00:25:15,700 you get it build up a dust in the 640 00:25:21,840 --> 00:25:18,130 ventilation system it starts to actually 641 00:25:24,090 --> 00:25:21,850 degrade the ventilation and so you have 642 00:25:27,240 --> 00:25:24,100 you monitor the air flow out of these 643 00:25:29,070 --> 00:25:27,250 vents and at a certain point you know 644 00:25:32,160 --> 00:25:29,080 it's time to go in and clean things up 645 00:25:35,750 --> 00:25:32,170 again it's tedious it's hard to do it 646 00:25:38,190 --> 00:25:35,760 repeatedly in exactly the same place 647 00:25:39,990 --> 00:25:38,200 well robots are good at that kind of 648 00:25:42,240 --> 00:25:40,000 thing they can get it back in the same 649 00:25:44,220 --> 00:25:42,250 place that he did it last time he could 650 00:25:47,130 --> 00:25:44,230 do it every time so you get a better 651 00:25:49,140 --> 00:25:47,140 measure sure of that and so your bill to 652 00:25:50,730 --> 00:25:49,150 do better trend tracking and it also 653 00:25:52,200 --> 00:25:50,740 doesn't take fruit on and it doesn't 654 00:25:53,820 --> 00:25:52,210 take crew time and that's the eventual 655 00:25:56,370 --> 00:25:53,830 goal is to have things like this that 656 00:25:59,040 --> 00:25:56,380 can help us out great well thank you 657 00:26:01,290 --> 00:25:59,050 guys so much for that so we have just a 658 00:26:04,200 --> 00:26:01,300 little bit of time well let's talk real 659 00:26:06,210 --> 00:26:04,210 quickly about earlier this morning pet I 660 00:26:08,280 --> 00:26:06,220 mean I'm sorry commander Burbank had 661 00:26:09,419 --> 00:26:08,290 actually done some quality water testing 662 00:26:11,910 --> 00:26:09,429 and the reason why I want to bring this 663 00:26:14,490 --> 00:26:11,920 up is that Earth Day is right around the 664 00:26:17,280 --> 00:26:14,500 corner it's on sunday april the 22nd and 665 00:26:19,080 --> 00:26:17,290 so i wanted to talk a little about you 666 00:26:21,170 --> 00:26:19,090 know the water quality testing but also 667 00:26:22,850 --> 00:26:21,180 more importantly the water reclamation 668 00:26:26,390 --> 00:26:22,860 you can just talked a little about that 669 00:26:28,460 --> 00:26:26,400 well the because of the logistics or the 670 00:26:30,860 --> 00:26:28,470 difficulty of launching water to space 671 00:26:32,300 --> 00:26:30,870 because it weighs you know one kilogram 672 00:26:34,160 --> 00:26:32,310 per liter no matter what you do you 673 00:26:36,470 --> 00:26:34,170 can't freeze dry it or anything else and 674 00:26:38,420 --> 00:26:36,480 so we've got to reuse as much water as 675 00:26:41,180 --> 00:26:38,430 possible on the station and that means 676 00:26:42,530 --> 00:26:41,190 reclaiming the condensation out of the 677 00:26:45,050 --> 00:26:42,540 air conditioning system that's 678 00:26:48,080 --> 00:26:45,060 reclaiming the water that we we exhale 679 00:26:49,910 --> 00:26:48,090 we breathe out or we sweat out when we 680 00:26:51,560 --> 00:26:49,920 have those sweaty gym clothes we let 681 00:26:53,660 --> 00:26:51,570 them dry out then we collect the water 682 00:26:56,600 --> 00:26:53,670 back in the through the air conditioning 683 00:27:00,830 --> 00:26:56,610 system put it into the purifier we also 684 00:27:02,840 --> 00:27:00,840 collect we reclaim part of the water out 685 00:27:05,120 --> 00:27:02,850 of the urine that we collect it goes 686 00:27:07,640 --> 00:27:05,130 into a system that helps evaporate out 687 00:27:10,280 --> 00:27:07,650 part of that water we don't get all of 688 00:27:11,900 --> 00:27:10,290 it but we get a about half of it and 689 00:27:13,610 --> 00:27:11,910 then that has to go through a whole 690 00:27:15,830 --> 00:27:13,620 purification system so you're getting 691 00:27:17,510 --> 00:27:15,840 condensation that's dripping out a lot 692 00:27:20,270 --> 00:27:17,520 of air flow picking up things from the 693 00:27:23,450 --> 00:27:20,280 atmosphere obviously the you know that 694 00:27:25,910 --> 00:27:23,460 the contaminants associated with with 695 00:27:29,300 --> 00:27:25,920 cleaning you know urine back into 696 00:27:31,370 --> 00:27:29,310 drinking water are very clear and and so 697 00:27:33,650 --> 00:27:31,380 we monitor this kind of stuff and the 698 00:27:36,470 --> 00:27:33,660 systems that we have to do that that 699 00:27:39,680 --> 00:27:36,480 they've come up with are actually being 700 00:27:42,410 --> 00:27:39,690 used now in disaster situations where 701 00:27:44,840 --> 00:27:42,420 you can take water but not as maybe not 702 00:27:47,000 --> 00:27:44,850 as dirty as exit pouring urine in one 703 00:27:48,800 --> 00:27:47,010 end but taking stream water or other 704 00:27:51,680 --> 00:27:48,810 water sources that are that are known 705 00:27:53,000 --> 00:27:51,690 not to be safe or suspect and putting 706 00:27:54,770 --> 00:27:53,010 them through the same kind of filter 707 00:27:56,210 --> 00:27:54,780 systems we're using on the space station 708 00:27:58,250 --> 00:27:56,220 that we've developed for the space 709 00:28:00,620 --> 00:27:58,260 station and and that's that's 710 00:28:03,140 --> 00:28:00,630 immediately providing water in disaster 711 00:28:05,000 --> 00:28:03,150 situations which is a you know a great 712 00:28:06,920 --> 00:28:05,010 way to bring some of that technology 713 00:28:08,720 --> 00:28:06,930 back to earth that's fascinating you 714 00:28:12,050 --> 00:28:08,730 know you know they say ingenuity is the 715 00:28:14,000 --> 00:28:12,060 mother of all invention so I'm necessity 716 00:28:16,250 --> 00:28:14,010 I'm sorry is the mother of invention so 717 00:28:18,260 --> 00:28:16,260 and it's interesting that we we do have 718 00:28:19,370 --> 00:28:18,270 some takeaways you know on some of the 719 00:28:21,620 --> 00:28:19,380 knowledge that will transform things 720 00:28:23,690 --> 00:28:21,630 from space station here back on earth 721 00:28:25,730 --> 00:28:23,700 you bet and so I think we're running 722 00:28:28,310 --> 00:28:25,740 just a little bit and close to you 723 00:28:32,030 --> 00:28:28,320 quittin time and so first I just want to 724 00:28:34,280 --> 00:28:32,040 mention that the progress and docking is 725 00:28:36,410 --> 00:28:34,290 again scheduled to take place at 726 00:28:38,630 --> 00:28:36,420 604 a.m. central time we'll have that 727 00:28:41,390 --> 00:28:38,640 televised here live on NASA television 728 00:28:44,210 --> 00:28:41,400 and that coverage will begin at 5 45 729 00:28:46,130 --> 00:28:44,220 a.m. again thanks so much for coming out 730 00:28:48,230 --> 00:28:46,140 and talking with us today it's always a 731 00:28:49,730 --> 00:28:48,240 pleasure it's great being here amico I
