going to be talking 4 00:00:08,790 --> 00:00:07,440 today about the spacewalk earlier this 5 00:00:11,270 --> 00:00:08,800 morning by chris cassidy and luca 6 00:00:13,110 --> 00:00:11,280 parmitano that was ended earlier than 7 00:00:15,350 --> 00:00:13,120 planned the spacewalk was due to last 8 00:00:16,950 --> 00:00:15,360 about six and a half hours to my left is 9 00:00:18,630 --> 00:00:16,960 kenny todd the chairman of the mission 10 00:00:20,150 --> 00:00:18,640 management team we're also joined by 11 00:00:22,150 --> 00:00:20,160 david korth who was the flight director 12 00:00:24,150 --> 00:00:22,160 on console today and we're also joined 13 00:00:25,670 --> 00:00:24,160 by karina eversley who is the spacewalk 14 00:00:27,750 --> 00:00:25,680 officer that was overseeing today's 15 00:00:28,630 --> 00:00:27,760 operations as well we'll hear from each 16 00:00:30,310 --> 00:00:28,640 one of them and we'll take some 17 00:00:31,910 --> 00:00:30,320 questions both here in houston at other 18 00:00:34,229 --> 00:00:31,920 nasa centers and also on the phone lines 19 00:00:35,830 --> 00:00:34,239 we'll get started with kenny 20 00:00:39,590 --> 00:00:35,840 thanks josh first of all 21 00:00:42,150 --> 00:00:39,600 i want to thank the ops team today 22 00:00:44,069 --> 00:00:42,160 the team had a good plan going in 23 00:00:46,310 --> 00:00:44,079 sometimes you have to adjust and this is 24 00:00:48,790 --> 00:00:46,320 one of those days where early on we had 25 00:00:50,310 --> 00:00:48,800 to make adjustments and and david karina 26 00:00:53,350 --> 00:00:50,320 and the rest of the ops team did a great 27 00:00:55,189 --> 00:00:53,360 job and uh and uh making sure that that 28 00:00:57,189 --> 00:00:55,199 we we did our number one objective which 29 00:00:59,910 --> 00:00:57,199 is to get the crew back in the airlock 30 00:01:02,470 --> 00:00:59,920 get them in into the iss safely and and 31 00:01:04,549 --> 00:01:02,480 that that goal was accomplished so uh 32 00:01:06,950 --> 00:01:04,559 from that standpoint i think i think we 33 00:01:09,109 --> 00:01:06,960 can all breathe a sigh of relief and say 34 00:01:12,789 --> 00:01:09,119 that indeed we did have some some 35 00:01:13,750 --> 00:01:12,799 success today so um crew's in good shape 36 00:01:16,789 --> 00:01:13,760 and 37 00:01:19,270 --> 00:01:16,799 you a little bit more about about the 38 00:01:21,270 --> 00:01:19,280 specifics of what happened today 39 00:01:22,870 --> 00:01:21,280 as far as where we go from here 40 00:01:24,870 --> 00:01:22,880 clearly we have a problem at this point 41 00:01:26,870 --> 00:01:24,880 that we don't quite understand and we're 42 00:01:28,149 --> 00:01:26,880 going to take the next day or two and 43 00:01:30,070 --> 00:01:28,159 and sort through that probably do a 44 00:01:31,749 --> 00:01:30,080 little bit of troubleshooting on orbit 45 00:01:33,429 --> 00:01:31,759 and the team will be working through the 46 00:01:34,789 --> 00:01:33,439 fault tree and and 47 00:01:36,870 --> 00:01:34,799 and trying to determine what kind of 48 00:01:38,870 --> 00:01:36,880 things that that we could do on orbit 49 00:01:40,149 --> 00:01:38,880 and and here on the ground to try to try 50 00:01:41,990 --> 00:01:40,159 to get a better understanding of what's 51 00:01:43,590 --> 00:01:42,000 going on so so that's that's kind of 52 00:01:46,550 --> 00:01:43,600 what i would term the immediate future 53 00:01:48,389 --> 00:01:46,560 as far as as where we're going to go 54 00:01:50,310 --> 00:01:48,399 past this do we need to go do this eva 55 00:01:52,630 --> 00:01:50,320 does it need to be done quickly 56 00:01:54,710 --> 00:01:52,640 that's just the the type of thing that 57 00:01:56,550 --> 00:01:54,720 through our normal uh processes here on 58 00:01:58,149 --> 00:01:56,560 the ground we'll we'll take the set of 59 00:02:00,230 --> 00:01:58,159 requirements that we have remaining and 60 00:02:01,590 --> 00:02:00,240 go try to try to bounce them up against 61 00:02:03,590 --> 00:02:01,600 the other things we need to do over the 62 00:02:05,590 --> 00:02:03,600 next several weeks and months and and 63 00:02:08,710 --> 00:02:05,600 we'll find the right time to to go do 64 00:02:11,190 --> 00:02:08,720 this eva once once we understand exactly 65 00:02:12,949 --> 00:02:11,200 what happened on orbit today and and how 66 00:02:14,309 --> 00:02:12,959 we can ensure that that it won't happen 67 00:02:17,270 --> 00:02:14,319 again so 68 00:02:19,670 --> 00:02:17,280 from that standpoint we have no 69 00:02:21,270 --> 00:02:19,680 no time clock that we're working to 70 00:02:22,869 --> 00:02:21,280 and and certainly when you have an issue 71 00:02:24,150 --> 00:02:22,879 like this you want to make sure that 72 00:02:26,070 --> 00:02:24,160 that you 73 00:02:28,309 --> 00:02:26,080 turn over every rock and and make sure 74 00:02:30,949 --> 00:02:28,319 that that that we've dealt with the with 75 00:02:32,550 --> 00:02:30,959 the issue and uh completely so 76 00:02:34,470 --> 00:02:32,560 with that that's uh that's kind of where 77 00:02:35,990 --> 00:02:34,480 we're at from a program standpoint i'll 78 00:02:37,830 --> 00:02:36,000 i'll hand it over to david and he can 79 00:02:39,830 --> 00:02:37,840 talk to you about the specifics of what 80 00:02:41,830 --> 00:02:39,840 happened today 81 00:02:44,229 --> 00:02:41,840 okay yeah what i'm going to do is i'll 82 00:02:45,750 --> 00:02:44,239 talk a bit at a higher level of 83 00:02:48,150 --> 00:02:45,760 kind of the timeline the flow of events 84 00:02:49,990 --> 00:02:48,160 today what we did accomplish a little 85 00:02:51,830 --> 00:02:50,000 bit of what happened and why we came in 86 00:02:54,790 --> 00:02:51,840 and i'll ask karina to fill in any 87 00:02:57,030 --> 00:02:54,800 specific details 88 00:02:58,710 --> 00:02:57,040 the crew was ready for the eva today as 89 00:02:59,910 --> 00:02:58,720 kenny mentioned we had a good plan going 90 00:03:00,710 --> 00:02:59,920 into it 91 00:03:02,550 --> 00:03:00,720 and 92 00:03:03,990 --> 00:03:02,560 in fact they started off about 18 93 00:03:05,270 --> 00:03:04,000 minutes ahead of the timeline getting 94 00:03:07,350 --> 00:03:05,280 out the door 95 00:03:09,030 --> 00:03:07,360 we knocked off the first two tasks that 96 00:03:11,190 --> 00:03:09,040 were planned for the eva 97 00:03:12,470 --> 00:03:11,200 and at one point chris was about 40 98 00:03:14,710 --> 00:03:12,480 minutes ahead 99 00:03:16,790 --> 00:03:14,720 of the timeline and it was about at that 100 00:03:19,670 --> 00:03:16,800 point where 101 00:03:21,190 --> 00:03:19,680 luca noted to us that he had a co2 102 00:03:22,790 --> 00:03:21,200 sensor 103 00:03:25,190 --> 00:03:22,800 in his system that that was bad he 104 00:03:27,190 --> 00:03:25,200 wasn't able to read a co2 anymore so we 105 00:03:29,270 --> 00:03:27,200 had some discussion on the ground 106 00:03:32,309 --> 00:03:29,280 and we have rules in place for how we 107 00:03:34,470 --> 00:03:32,319 handle uh bad co2 sensors and we can 108 00:03:36,710 --> 00:03:34,480 monitor the the co2 level 109 00:03:38,789 --> 00:03:36,720 of the the crew to keep them safe and 110 00:03:39,910 --> 00:03:38,799 just rely on them really to report any 111 00:03:42,869 --> 00:03:39,920 uh 112 00:03:44,149 --> 00:03:42,879 symptoms of co2 and we progressed from 113 00:03:46,630 --> 00:03:44,159 there 114 00:03:48,550 --> 00:03:46,640 and had the crew at that point 115 00:03:51,350 --> 00:03:48,560 uh luca had already finished uh the 116 00:03:53,430 --> 00:03:51,360 first task of the day which was the uh 117 00:03:55,589 --> 00:03:53,440 grapple fixture on the fgb making the 118 00:03:58,309 --> 00:03:55,599 final data connections we we routed the 119 00:04:00,630 --> 00:03:58,319 cable you recall on the last dva and we 120 00:04:02,070 --> 00:04:00,640 just made the final connections to get 121 00:04:03,990 --> 00:04:02,080 that in good shape 122 00:04:06,789 --> 00:04:04,000 and he was starting into the 123 00:04:08,470 --> 00:04:06,799 mlm ethernet cable hookup and then he 124 00:04:10,949 --> 00:04:08,480 was going to route it and it was at that 125 00:04:12,470 --> 00:04:10,959 point as i mentioned co2 cents are bad 126 00:04:13,990 --> 00:04:12,480 we talked about it a bit and then about 127 00:04:15,110 --> 00:04:14,000 six seven minutes later he started 128 00:04:16,629 --> 00:04:15,120 reporting 129 00:04:20,789 --> 00:04:16,639 uh water 130 00:04:22,550 --> 00:04:20,799 his head 131 00:04:24,629 --> 00:04:22,560 specifically kind of a 132 00:04:26,230 --> 00:04:24,639 gush or whatever just kind of a bubble 133 00:04:27,430 --> 00:04:26,240 in the back of his head 134 00:04:29,270 --> 00:04:27,440 and 135 00:04:31,670 --> 00:04:29,280 we uh we talked about it with him tried 136 00:04:33,670 --> 00:04:31,680 to get a sense of uh did it just appear 137 00:04:35,110 --> 00:04:33,680 has it been increasing and and the sense 138 00:04:37,350 --> 00:04:35,120 we got at the time 139 00:04:38,870 --> 00:04:37,360 was that and and as well from his 140 00:04:40,790 --> 00:04:38,880 perspective that 141 00:04:42,870 --> 00:04:40,800 uh things were okay stabilized he just 142 00:04:44,230 --> 00:04:42,880 had this water accumulation in the back 143 00:04:47,189 --> 00:04:44,240 of his head 144 00:04:50,230 --> 00:04:47,199 and we drew the conclusion that the co2 145 00:04:52,070 --> 00:04:50,240 sensor bad uh was probably related to 146 00:04:54,550 --> 00:04:52,080 the fact that the water accumulation we 147 00:04:56,710 --> 00:04:54,560 have a history of you know co2 sensors 148 00:04:58,950 --> 00:04:56,720 getting wet and it kind of makes them go 149 00:05:00,230 --> 00:04:58,960 bad anyways we started to talk about 150 00:05:03,030 --> 00:05:00,240 next steps 151 00:05:05,430 --> 00:05:03,040 and karina suggested that we hold right 152 00:05:07,590 --> 00:05:05,440 there and talk through any implications 153 00:05:08,550 --> 00:05:07,600 to the suit and whether we are happy 154 00:05:09,430 --> 00:05:08,560 with 155 00:05:11,430 --> 00:05:09,440 luca 156 00:05:13,909 --> 00:05:11,440 continuing with his tasks 157 00:05:15,909 --> 00:05:13,919 and not long after that 158 00:05:17,830 --> 00:05:15,919 chris chris was finished with his task 159 00:05:20,629 --> 00:05:17,840 which was the z1 wipe 160 00:05:23,350 --> 00:05:20,639 y cable jumper install 161 00:05:25,029 --> 00:05:23,360 part two we did part one of the last eva 162 00:05:27,029 --> 00:05:25,039 he finished it he was coming over to 163 00:05:28,629 --> 00:05:27,039 look at luca and kind of assess the 164 00:05:30,950 --> 00:05:28,639 situation he said hey there's there's a 165 00:05:33,350 --> 00:05:30,960 larger accumulation of water now around 166 00:05:35,430 --> 00:05:33,360 lucca and he started reporting that 167 00:05:37,350 --> 00:05:35,440 it was coming around his ears 168 00:05:39,110 --> 00:05:37,360 and getting on the front of his face and 169 00:05:40,950 --> 00:05:39,120 it was at that point that uh you know 170 00:05:42,950 --> 00:05:40,960 per the rules and guidelines we have we 171 00:05:45,029 --> 00:05:42,960 judge that it was in the best interest 172 00:05:47,189 --> 00:05:45,039 of the crew and the mission of the the 173 00:05:49,350 --> 00:05:47,199 task that day that we would call 174 00:05:51,350 --> 00:05:49,360 terminate the eva 175 00:05:54,790 --> 00:05:51,360 we just weren't gonna it wasn't 176 00:05:56,950 --> 00:05:54,800 uh prudent to try to continue tasks 177 00:05:58,710 --> 00:05:56,960 with uh water accumulating around his 178 00:05:59,990 --> 00:05:58,720 ears and and the discomfort that he had 179 00:06:02,469 --> 00:06:00,000 at that point 180 00:06:03,670 --> 00:06:02,479 and so we directed luca to head back to 181 00:06:05,670 --> 00:06:03,680 the airlock 182 00:06:08,390 --> 00:06:05,680 we told chris in the situation we have 183 00:06:10,790 --> 00:06:08,400 here to save the uh the bags that he had 184 00:06:12,150 --> 00:06:10,800 at that point and then follow luca back 185 00:06:14,230 --> 00:06:12,160 to the airlock 186 00:06:15,189 --> 00:06:14,240 uh luca ended up going in the airlock 187 00:06:19,189 --> 00:06:15,199 first 188 00:06:20,950 --> 00:06:19,199 one bag back in 189 00:06:22,550 --> 00:06:20,960 with these large v guides that was one 190 00:06:23,749 --> 00:06:22,560 of the tasks that he was just about to 191 00:06:25,189 --> 00:06:23,759 go work on 192 00:06:27,029 --> 00:06:25,199 he had those in the bag he brought those 193 00:06:28,070 --> 00:06:27,039 back inside 194 00:06:29,830 --> 00:06:28,080 and 195 00:06:32,150 --> 00:06:29,840 at about 196 00:06:34,629 --> 00:06:32,160 1305 let's see no 197 00:06:37,670 --> 00:06:34,639 1326 gmt we had a both crew in the 198 00:06:38,629 --> 00:06:37,680 airlock hatches closed and we at that 199 00:06:40,309 --> 00:06:38,639 point 200 00:06:42,150 --> 00:06:40,319 started getting reports from from both 201 00:06:44,469 --> 00:06:42,160 chris and luca that the amount of water 202 00:06:45,590 --> 00:06:44,479 accumulating in in his helmet was was 203 00:06:47,270 --> 00:06:45,600 increasing 204 00:06:50,070 --> 00:06:47,280 uh so we went through what we call an 205 00:06:51,670 --> 00:06:50,080 expedited suit doffing procedure which 206 00:06:54,070 --> 00:06:51,680 skips some of the 207 00:06:55,510 --> 00:06:54,080 while more methodical steps of of 208 00:06:56,870 --> 00:06:55,520 getting the crew 209 00:06:57,830 --> 00:06:56,880 configured 210 00:06:59,270 --> 00:06:57,840 for 211 00:07:01,350 --> 00:06:59,280 getting out of their suits and doffing 212 00:07:03,110 --> 00:07:01,360 their suits it hits hits to cuts to the 213 00:07:04,629 --> 00:07:03,120 chase and gets them out of their suits 214 00:07:06,230 --> 00:07:04,639 quicker and especially in this case 215 00:07:09,189 --> 00:07:06,240 getting the helmet off 216 00:07:11,749 --> 00:07:09,199 so we we took those steps and uh 217 00:07:14,230 --> 00:07:11,759 about 10 12 minutes later we got uh luca 218 00:07:16,150 --> 00:07:14,240 had his helmet and glove off gloves off 219 00:07:17,749 --> 00:07:16,160 and uh at that point we we started to 220 00:07:19,510 --> 00:07:17,759 get assessment of how much water we were 221 00:07:21,909 --> 00:07:19,520 talking about in there and the reports 222 00:07:25,270 --> 00:07:21,919 we got was anywhere between a liter and 223 00:07:27,110 --> 00:07:25,280 1.5 liters of water had accumulated in 224 00:07:29,189 --> 00:07:27,120 the suit itself not just in the helmet 225 00:07:31,589 --> 00:07:29,199 but all around the suit 226 00:07:33,830 --> 00:07:31,599 so as kenny mentioned there's been a lot 227 00:07:35,510 --> 00:07:33,840 of discussion with both the crew and all 228 00:07:37,510 --> 00:07:35,520 the engineering teams to try to 229 00:07:39,990 --> 00:07:37,520 determine what what exactly is the the 230 00:07:41,909 --> 00:07:40,000 source of the water 231 00:07:43,749 --> 00:07:41,919 what happened the suits are 232 00:07:45,430 --> 00:07:43,759 by all means the rest of the the suits 233 00:07:46,390 --> 00:07:45,440 are in good shape the crew is in good 234 00:07:47,189 --> 00:07:46,400 shape 235 00:07:48,309 --> 00:07:47,199 um 236 00:07:49,909 --> 00:07:48,319 they're 237 00:07:51,510 --> 00:07:49,919 of course interested as we are to find 238 00:07:53,189 --> 00:07:51,520 out what what happened and what caused 239 00:07:55,029 --> 00:07:53,199 the eva to 240 00:07:57,430 --> 00:07:55,039 terminate a little early we we did get a 241 00:07:58,950 --> 00:07:57,440 total of an hour and 32 minutes of pet 242 00:08:00,790 --> 00:07:58,960 time so 243 00:08:02,390 --> 00:08:00,800 that qualifies to give them their eva 244 00:08:04,309 --> 00:08:02,400 wings at least on this eva but it's 245 00:08:06,309 --> 00:08:04,319 their second eva 246 00:08:09,350 --> 00:08:06,319 so those are those are the main parts of 247 00:08:12,230 --> 00:08:09,360 the timeline how things flowed and and 248 00:08:13,430 --> 00:08:12,240 how the events transpired so i'll turn 249 00:08:15,189 --> 00:08:13,440 over to karina if you have any other 250 00:08:17,350 --> 00:08:15,199 details you want to add 251 00:08:19,510 --> 00:08:17,360 i think you covered the timeline pretty 252 00:08:20,550 --> 00:08:19,520 well david um i just want to reiterate 253 00:08:22,469 --> 00:08:20,560 that 254 00:08:24,309 --> 00:08:22,479 you know it's a good day today the crew 255 00:08:26,550 --> 00:08:24,319 is inside and safe and they're in good 256 00:08:28,710 --> 00:08:26,560 spirits we just spoke with them to ask 257 00:08:30,629 --> 00:08:28,720 them some more questions about the suit 258 00:08:32,949 --> 00:08:30,639 and what they saw 259 00:08:34,949 --> 00:08:32,959 and that will be excellent information 260 00:08:36,790 --> 00:08:34,959 for our engineering teams on the ground 261 00:08:39,350 --> 00:08:36,800 trying to determine what the source was 262 00:08:41,029 --> 00:08:39,360 of this water 263 00:08:43,509 --> 00:08:41,039 you know space walks are 264 00:08:45,190 --> 00:08:43,519 really a key part of the human 265 00:08:47,670 --> 00:08:45,200 space flight program 266 00:08:50,870 --> 00:08:47,680 and they can do some spectacular things 267 00:08:51,910 --> 00:08:50,880 we've had some fantastic victories with 268 00:08:53,590 --> 00:08:51,920 nothing less than building the 269 00:08:55,670 --> 00:08:53,600 international space station but of 270 00:08:56,870 --> 00:08:55,680 course all space flight does have risks 271 00:08:59,590 --> 00:08:56,880 and 272 00:09:01,750 --> 00:08:59,600 so does spacewalks 273 00:09:03,350 --> 00:09:01,760 the team today i have a fantastic team 274 00:09:05,110 --> 00:09:03,360 that was supporting me 275 00:09:08,070 --> 00:09:05,120 on the ground as well as the fantastic 276 00:09:10,550 --> 00:09:08,080 team on orbit and everybody performed 277 00:09:12,389 --> 00:09:10,560 very very well and so we made the 278 00:09:15,190 --> 00:09:12,399 decision very quickly to terminate the 279 00:09:18,389 --> 00:09:15,200 eva when we understood the situation 280 00:09:20,710 --> 00:09:18,399 with the water in lucca's helmet 281 00:09:23,110 --> 00:09:20,720 and i just want to say we simulate these 282 00:09:25,350 --> 00:09:23,120 types of things on the ground and that's 283 00:09:27,269 --> 00:09:25,360 so that we can perform under pressure 284 00:09:30,949 --> 00:09:27,279 the kind of way that we did today and 285 00:09:34,310 --> 00:09:33,190 there's a couple of numbers i can 286 00:09:36,389 --> 00:09:34,320 hand out that i think folks will 287 00:09:38,949 --> 00:09:36,399 probably be interested in 288 00:09:40,070 --> 00:09:38,959 sources of water in the suit 289 00:09:43,110 --> 00:09:40,080 of course one of the first things we 290 00:09:45,350 --> 00:09:43,120 often think about is the drink bag 291 00:09:46,550 --> 00:09:45,360 crew is outside for six and a half hours 292 00:09:48,630 --> 00:09:46,560 and so it's very important that they 293 00:09:51,190 --> 00:09:48,640 have a drink bag so that they can remain 294 00:09:52,630 --> 00:09:51,200 hydrated during what can be some pretty 295 00:09:55,350 --> 00:09:52,640 hard work 296 00:09:56,310 --> 00:09:55,360 our drink bag holds 32 ounces 297 00:09:57,990 --> 00:09:56,320 and 298 00:09:59,990 --> 00:09:58,000 obviously another source of moisture in 299 00:10:01,670 --> 00:10:00,000 the suit can be the crew sweating when 300 00:10:03,509 --> 00:10:01,680 they're working hard but that's not the 301 00:10:05,190 --> 00:10:03,519 type of that obviously is not going to 302 00:10:06,630 --> 00:10:05,200 create the kind of 303 00:10:08,150 --> 00:10:06,640 quantity of water that the crew was 304 00:10:10,470 --> 00:10:08,160 reporting 305 00:10:12,870 --> 00:10:10,480 and then in our cooling system we have 306 00:10:14,630 --> 00:10:12,880 about a gallon of water between 307 00:10:18,069 --> 00:10:14,640 the liquid cooling and ventilation 308 00:10:20,470 --> 00:10:18,079 garment and the water tanks that provide 309 00:10:25,670 --> 00:10:20,480 water to our sublimator which helps then 310 00:10:30,069 --> 00:10:27,269 and the liquid cooling and ventilation 311 00:10:31,829 --> 00:10:30,079 garment holds about an eighth of that 312 00:10:33,910 --> 00:10:31,839 volume so those were the things that we 313 00:10:37,509 --> 00:10:33,920 were thinking about as possible sources 314 00:10:39,910 --> 00:10:37,519 during the eva from words that the crew 315 00:10:42,069 --> 00:10:39,920 reported we think it's unlikely that it 316 00:10:45,269 --> 00:10:42,079 was the drink bag today 317 00:10:47,590 --> 00:10:45,279 and i would say that i don't know yet uh 318 00:10:49,269 --> 00:10:47,600 the exact source of the water today so 319 00:10:50,949 --> 00:10:49,279 that's part of the investigation that's 320 00:10:53,269 --> 00:10:50,959 going to be going forward 321 00:10:54,389 --> 00:10:53,279 and that's about all i have 322 00:10:55,670 --> 00:10:54,399 okay we're going to start off with 323 00:10:57,190 --> 00:10:55,680 questions here in houston we'll go to 324 00:10:58,470 --> 00:10:57,200 the phone lines let's start down here 325 00:11:00,790 --> 00:10:58,480 with uh gina 326 00:11:03,190 --> 00:11:00,800 uh genus cinceri abc news i've got a 327 00:11:05,829 --> 00:11:03,200 couple of questions um was there any 328 00:11:07,750 --> 00:11:05,839 danger of him drowning in his helmet was 329 00:11:10,710 --> 00:11:07,760 that a concern for you at all have you 330 00:11:12,230 --> 00:11:10,720 ever seen a problem like this before 331 00:11:14,389 --> 00:11:12,240 i would say no we have not seen a 332 00:11:16,630 --> 00:11:14,399 problem like this before with this type 333 00:11:18,389 --> 00:11:16,640 of quantity of water 334 00:11:20,069 --> 00:11:18,399 concerns with water in the suit 335 00:11:22,310 --> 00:11:20,079 especially free water 336 00:11:23,990 --> 00:11:22,320 one of the things that we worry about is 337 00:11:25,750 --> 00:11:24,000 the anti-fog on the 338 00:11:27,910 --> 00:11:25,760 helmet which has a 339 00:11:29,509 --> 00:11:27,920 soapy material now often divers for 340 00:11:31,350 --> 00:11:29,519 instance may put a soapy material inside 341 00:11:32,870 --> 00:11:31,360 their 342 00:11:34,790 --> 00:11:32,880 goggles to 343 00:11:37,110 --> 00:11:34,800 keep them from 344 00:11:38,470 --> 00:11:37,120 from being fogged up and 345 00:11:41,030 --> 00:11:38,480 right and so 346 00:11:43,110 --> 00:11:41,040 we've seen water small amounts of water 347 00:11:44,470 --> 00:11:43,120 get in that and then get in the crew's 348 00:11:46,069 --> 00:11:44,480 eyes and that can be very painful so 349 00:11:47,990 --> 00:11:46,079 that was obviously one concern that 350 00:11:49,910 --> 00:11:48,000 popped up ahead 351 00:11:51,190 --> 00:11:49,920 hearing and communication and we did see 352 00:11:53,990 --> 00:11:51,200 that today 353 00:11:56,310 --> 00:11:54,000 that enough water was in lucca's calm 354 00:11:58,069 --> 00:11:56,320 cap that it blocked his ability to hear 355 00:11:59,350 --> 00:11:58,079 towards the end as he was coming into 356 00:12:02,710 --> 00:11:59,360 the airlock 357 00:12:04,790 --> 00:12:02,720 and yes if there's enough water and 358 00:12:05,509 --> 00:12:04,800 the interesting thing in zero gravity 359 00:12:07,350 --> 00:12:05,519 that 360 00:12:09,350 --> 00:12:07,360 folks on the ground may not be aware of 361 00:12:10,629 --> 00:12:09,360 is you know the water pools 362 00:12:13,030 --> 00:12:10,639 in a big glob 363 00:12:14,470 --> 00:12:13,040 and so it doesn't necessarily go down 364 00:12:17,030 --> 00:12:14,480 into the suit and there's not a lot of 365 00:12:19,430 --> 00:12:17,040 absorptive material in the helmet so he 366 00:12:21,269 --> 00:12:19,440 he certainly had that risk today and 367 00:12:22,629 --> 00:12:21,279 that's why we took it so seriously and 368 00:12:24,310 --> 00:12:22,639 terminated the eva as soon as we 369 00:12:25,670 --> 00:12:24,320 understood that we were dealing with 370 00:12:28,470 --> 00:12:25,680 quantities of water and not just 371 00:12:31,910 --> 00:12:30,310 how has he recovered what are the after 372 00:12:33,990 --> 00:12:31,920 effects what have you seen so far that 373 00:12:36,470 --> 00:12:34,000 you're allowed to share with us luke is 374 00:12:38,150 --> 00:12:36,480 doing great he's he's smiling and happy 375 00:12:40,470 --> 00:12:38,160 and he's 376 00:12:42,389 --> 00:12:40,480 all the crew is looking at the suits and 377 00:12:44,069 --> 00:12:42,399 reporting information anything that they 378 00:12:45,750 --> 00:12:44,079 can to help us 379 00:12:47,590 --> 00:12:45,760 investigate the source 380 00:12:49,670 --> 00:12:47,600 yeah i would say grace under pressure 381 00:12:51,670 --> 00:12:49,680 because you know as we we learned 382 00:12:53,269 --> 00:12:51,680 as he progressed back toward the airlock 383 00:12:54,710 --> 00:12:53,279 you know the amount of water that he was 384 00:12:56,470 --> 00:12:54,720 reporting started to increase and 385 00:12:59,030 --> 00:12:56,480 increase and you can imagine 386 00:13:00,629 --> 00:12:59,040 you know you're in a fish bowl 387 00:13:02,710 --> 00:13:00,639 so go stick your head in the fishbowl 388 00:13:04,629 --> 00:13:02,720 and try to walk around and that's not 389 00:13:07,350 --> 00:13:04,639 anything that you you take lightly and 390 00:13:09,110 --> 00:13:07,360 certainly eva is dangerous already 391 00:13:11,509 --> 00:13:09,120 and he did a great job 392 00:13:14,949 --> 00:13:11,519 of just keeping calm and cool and 393 00:13:19,269 --> 00:13:16,949 okay well 394 00:13:21,750 --> 00:13:19,279 robert perrman with collectface.com 395 00:13:23,910 --> 00:13:21,760 um david you mentioned that there was an 396 00:13:26,069 --> 00:13:23,920 expedited suit doffing but from the 397 00:13:27,750 --> 00:13:26,079 point that i guess the first call was 398 00:13:29,430 --> 00:13:27,760 that you were 399 00:13:31,430 --> 00:13:29,440 ending the eva to the point that they 400 00:13:32,710 --> 00:13:31,440 reached the airlock was about 25 minutes 401 00:13:35,590 --> 00:13:32,720 and then it took another 10 minutes to 402 00:13:37,190 --> 00:13:35,600 repress if luca had been in a more 403 00:13:39,590 --> 00:13:37,200 serious situation with more water 404 00:13:42,150 --> 00:13:39,600 flowing in was that the fastest that you 405 00:13:43,350 --> 00:13:42,160 could get his helmet off or was there 406 00:13:45,910 --> 00:13:43,360 something else that you could have done 407 00:13:48,949 --> 00:13:45,920 to purge the water from the helmet 408 00:13:50,389 --> 00:13:48,959 before we press or before literally 409 00:13:52,790 --> 00:13:50,399 taking the helmet off 410 00:13:54,550 --> 00:13:52,800 yeah good question yeah we actually have 411 00:14:00,629 --> 00:13:54,560 uh 412 00:14:02,710 --> 00:14:00,639 could even ratchet up if we needed to 413 00:14:04,710 --> 00:14:02,720 the expedition 414 00:14:06,389 --> 00:14:04,720 expeditious 415 00:14:08,710 --> 00:14:06,399 traverse back to the airlock we call it 416 00:14:10,710 --> 00:14:08,720 an abort eva scenario 417 00:14:13,509 --> 00:14:10,720 where we think at that moment 418 00:14:15,269 --> 00:14:13,519 cruz life is is imminently in danger we 419 00:14:16,790 --> 00:14:15,279 did not at the point 420 00:14:18,470 --> 00:14:16,800 sense that that was the case we took 421 00:14:20,790 --> 00:14:18,480 action at the appropriate time so that 422 00:14:22,389 --> 00:14:20,800 that was not going to be the case 423 00:14:25,030 --> 00:14:22,399 but we could have 424 00:14:26,310 --> 00:14:25,040 expedited getting back to the airlock 425 00:14:27,910 --> 00:14:26,320 and then once in the airlock do an 426 00:14:29,990 --> 00:14:27,920 emergency repress 427 00:14:32,310 --> 00:14:30,000 karina mayo can share more details about 428 00:14:34,790 --> 00:14:32,320 what's involved in emergency repress 429 00:14:36,389 --> 00:14:34,800 it cuts a lot more corners and 430 00:14:38,949 --> 00:14:36,399 now there's a lot more 431 00:14:41,110 --> 00:14:38,959 less system reconfig involved and you 432 00:14:42,870 --> 00:14:41,120 only do that if you feel like a crew 433 00:14:46,870 --> 00:14:42,880 member's life is absolutely in danger at 434 00:14:52,389 --> 00:14:49,509 um how do you troubleshoot this can you 435 00:14:54,470 --> 00:14:52,399 um do you have to put back this suit 436 00:14:56,710 --> 00:14:54,480 together and prepare it for another walk 437 00:14:57,990 --> 00:14:56,720 and have it run empty or how do you 438 00:14:59,670 --> 00:14:58,000 figure out where the water is coming 439 00:15:01,829 --> 00:14:59,680 from yeah it's a that's a great question 440 00:15:02,790 --> 00:15:01,839 what we've started with today throughout 441 00:15:05,110 --> 00:15:02,800 the day 442 00:15:07,110 --> 00:15:05,120 is a detailed discussions with the crew 443 00:15:08,870 --> 00:15:07,120 to get their sense of 444 00:15:10,629 --> 00:15:08,880 where did they see the feel the water 445 00:15:13,430 --> 00:15:10,639 was coming from 446 00:15:15,990 --> 00:15:13,440 how much water and detailed inspections 447 00:15:18,150 --> 00:15:16,000 we the crew has been great about uh 448 00:15:20,389 --> 00:15:18,160 video and photography of the inside of 449 00:15:21,910 --> 00:15:20,399 the suit all aspects of the suit uh to 450 00:15:23,750 --> 00:15:21,920 help the engineers kind of determine 451 00:15:26,389 --> 00:15:23,760 what could be the problem 452 00:15:27,910 --> 00:15:26,399 nothing is jumping out right now 453 00:15:30,310 --> 00:15:27,920 as to what the source is as karina 454 00:15:32,470 --> 00:15:30,320 mentioned you know we originally thought 455 00:15:34,550 --> 00:15:32,480 the easy go for solution is the drink 456 00:15:36,870 --> 00:15:34,560 bag and i think we've pretty much ruled 457 00:15:38,069 --> 00:15:36,880 that out not entirely but that doesn't 458 00:15:40,710 --> 00:15:38,079 seem to be 459 00:15:41,990 --> 00:15:40,720 the the immediate source so uh that's 460 00:15:44,150 --> 00:15:42,000 that's the approach we take the 461 00:15:45,829 --> 00:15:44,160 engineering teams are meeting right now 462 00:15:47,350 --> 00:15:45,839 um to go through the photos that the 463 00:15:49,590 --> 00:15:47,360 crew has taken 464 00:15:53,430 --> 00:15:49,600 and the uh reviewing the uh discussion 465 00:15:55,590 --> 00:15:53,440 we've had with them on space to ground 466 00:15:57,670 --> 00:15:55,600 okay mark 467 00:15:58,710 --> 00:15:57,680 thank you mark mark rowe for aviation 468 00:16:00,870 --> 00:15:58,720 week 469 00:16:04,150 --> 00:16:00,880 um 470 00:16:06,870 --> 00:16:04,160 what does the current situation say 471 00:16:08,870 --> 00:16:06,880 about your ability to respond 472 00:16:10,710 --> 00:16:08,880 rather quickly if you had to to some 473 00:16:11,910 --> 00:16:10,720 other issue like a thermal control 474 00:16:14,790 --> 00:16:11,920 system 475 00:16:16,870 --> 00:16:14,800 problem or something with the power 476 00:16:18,870 --> 00:16:16,880 source outside the station can you can 477 00:16:20,790 --> 00:16:18,880 you still do it while you investigate 478 00:16:22,389 --> 00:16:20,800 when you hold that up or is that sort of 479 00:16:24,629 --> 00:16:22,399 a question that doesn't have an answer 480 00:16:26,470 --> 00:16:24,639 yet 481 00:16:28,230 --> 00:16:26,480 i know i can i can try a little bit and 482 00:16:29,670 --> 00:16:28,240 i'll let kenny answer 483 00:16:32,069 --> 00:16:29,680 the uh 484 00:16:34,550 --> 00:16:32,079 there are you know if if and a lot of it 485 00:16:35,990 --> 00:16:34,560 depends on what we determine 486 00:16:37,590 --> 00:16:36,000 while the engineers go through the the 487 00:16:39,430 --> 00:16:37,600 situation tonight and 488 00:16:41,269 --> 00:16:39,440 what the nature of this problem is is it 489 00:16:43,509 --> 00:16:41,279 a pervasive problem that we need to 490 00:16:45,350 --> 00:16:43,519 worry about all the emus or not 491 00:16:47,030 --> 00:16:45,360 if it really is something very specific 492 00:16:48,150 --> 00:16:47,040 to this suit 493 00:16:50,550 --> 00:16:48,160 we have 494 00:16:53,030 --> 00:16:50,560 procedures for the crew to resize 495 00:16:55,110 --> 00:16:53,040 and getting some different uh upper 496 00:16:56,790 --> 00:16:55,120 torsos and things like that so that we 497 00:16:58,310 --> 00:16:56,800 could go eva if we needed to for an 498 00:17:00,629 --> 00:16:58,320 emergency but it really is going to 499 00:17:01,749 --> 00:17:00,639 depend on what they learn and if they 500 00:17:04,230 --> 00:17:01,759 can 501 00:17:06,069 --> 00:17:04,240 pinpoint this as a unique suit issue or 502 00:17:06,900 --> 00:17:06,079 not 503 00:17:08,470 --> 00:17:06,910 i think 504 00:17:11,029 --> 00:17:08,480 [Applause] 505 00:17:13,350 --> 00:17:11,039 it was i mean we have redundancy suits 506 00:17:15,270 --> 00:17:13,360 on board they may not be the exact size 507 00:17:17,909 --> 00:17:15,280 but we have ways to to work around that 508 00:17:20,150 --> 00:17:17,919 and have worked around it in the past so 509 00:17:22,390 --> 00:17:20,160 we would be in a position to be able to 510 00:17:24,549 --> 00:17:22,400 respond from a hardware standpoint and 511 00:17:26,710 --> 00:17:24,559 being able to go out i think it becomes 512 00:17:28,470 --> 00:17:26,720 what do we know about this failure 513 00:17:30,630 --> 00:17:28,480 you know how stable are we with with 514 00:17:33,190 --> 00:17:30,640 whatever is going on outside 515 00:17:35,669 --> 00:17:33,200 sometimes you know we'll lose a loop and 516 00:17:37,590 --> 00:17:35,679 that'll take us down to the point where 517 00:17:39,110 --> 00:17:37,600 where we're you know single or zero 518 00:17:41,110 --> 00:17:39,120 fault tolerant on some systems and we 519 00:17:43,350 --> 00:17:41,120 want to get out sooner rather than later 520 00:17:44,789 --> 00:17:43,360 but we would trade that risk against you 521 00:17:46,310 --> 00:17:44,799 know what we know and don't know about 522 00:17:48,549 --> 00:17:46,320 this particular failure let's say if it 523 00:17:50,310 --> 00:17:48,559 were to happen tonight or tomorrow 524 00:17:52,150 --> 00:17:50,320 we clearly would want to 525 00:17:54,950 --> 00:17:52,160 to balance that risk to the best we can 526 00:17:56,230 --> 00:17:54,960 and that's uh and that's what we do 527 00:17:58,549 --> 00:17:56,240 okay one more down here and then we'll 528 00:18:01,669 --> 00:17:58,559 go to the phone lines uh mr todd what 529 00:18:03,909 --> 00:18:01,679 did you learn from this today 530 00:18:05,830 --> 00:18:03,919 well um 531 00:18:07,909 --> 00:18:05,840 what i learned from from the standpoint 532 00:18:09,830 --> 00:18:07,919 of the ops team was that those guys are 533 00:18:11,990 --> 00:18:09,840 ready to go you know if you could have 534 00:18:13,990 --> 00:18:12,000 heard the back traffic here and as they 535 00:18:16,070 --> 00:18:14,000 discussed you know what the situation 536 00:18:18,789 --> 00:18:16,080 was with the crew do we you know there 537 00:18:19,990 --> 00:18:18,799 wasn't any doubt as to as to how to how 538 00:18:22,710 --> 00:18:20,000 to get this done and get it done 539 00:18:25,190 --> 00:18:22,720 successfully it was uh really uh all the 540 00:18:27,750 --> 00:18:25,200 training clearly was was paid off and as 541 00:18:30,710 --> 00:18:27,760 far as as far as the crew goes uh you 542 00:18:32,950 --> 00:18:30,720 know the crew was top-notch experts and 543 00:18:34,630 --> 00:18:32,960 and they were really um you know they 544 00:18:36,630 --> 00:18:34,640 were they were part of the team and they 545 00:18:38,870 --> 00:18:36,640 were helping to work through this and 546 00:18:41,350 --> 00:18:38,880 and uh at the end of the day uh like i 547 00:18:44,230 --> 00:18:41,360 said we we accomplished objective one 548 00:18:45,750 --> 00:18:44,240 and uh and i think it uh it brought into 549 00:18:48,150 --> 00:18:45,760 mind for all of us that's really what 550 00:18:50,789 --> 00:18:48,160 this is all about is to uh is to go do 551 00:18:52,950 --> 00:18:50,799 this risky operation the best way we can 552 00:18:56,070 --> 00:18:52,960 to ensure that we we protect the main 553 00:18:57,190 --> 00:18:56,080 objective and uh and today uh you know 554 00:18:59,270 --> 00:18:57,200 um 555 00:19:01,510 --> 00:18:59,280 we we have to do eva's ebas are part of 556 00:19:03,270 --> 00:19:01,520 this business and i think what at least 557 00:19:05,830 --> 00:19:03,280 i walked away from this today is saying 558 00:19:07,990 --> 00:19:05,840 that indeed that when we have that day 559 00:19:09,750 --> 00:19:08,000 that we we really wouldn't like to have 560 00:19:11,669 --> 00:19:09,760 the team is really ready to respond and 561 00:19:13,190 --> 00:19:11,679 so so it was a 562 00:19:15,110 --> 00:19:13,200 from that standpoint i don't walk away 563 00:19:16,630 --> 00:19:15,120 with my head down i walk away saying 564 00:19:19,029 --> 00:19:16,640 sometimes you get judged by how you 565 00:19:21,270 --> 00:19:19,039 respond when bad things happen and today 566 00:19:22,789 --> 00:19:21,280 the team did a great job 567 00:19:24,549 --> 00:19:22,799 okay let's go to the phone lines now i'm 568 00:19:25,830 --> 00:19:24,559 going to call on them as we go down the 569 00:19:27,110 --> 00:19:25,840 line just a reminder keep your phone on 570 00:19:31,669 --> 00:19:27,120 mute until i'm calling you let's start 571 00:19:35,990 --> 00:19:32,950 good afternoon charles action 572 00:19:37,669 --> 00:19:36,000 examiner.com uh once back inside the 573 00:19:40,150 --> 00:19:37,679 station luca said that the drinking 574 00:19:42,310 --> 00:19:40,160 water tasted really funny and not like 575 00:19:44,390 --> 00:19:42,320 any normal drinking water would would 576 00:19:46,390 --> 00:19:44,400 that point you more towards the water 577 00:19:48,470 --> 00:19:46,400 coolant or the suit 578 00:19:49,350 --> 00:19:48,480 and then i have a follow-up that has to 579 00:19:51,350 --> 00:19:49,360 do with 580 00:19:53,350 --> 00:19:51,360 if you have a pinhole leak out of 581 00:19:55,110 --> 00:19:53,360 example how would the leak 582 00:19:56,150 --> 00:19:55,120 begin to move up to the suit to the 583 00:19:57,990 --> 00:19:56,160 helmet 584 00:20:00,150 --> 00:19:58,000 because cassidy had radioed to houston 585 00:20:03,590 --> 00:20:00,160 that his pants so that lucas pants were 586 00:20:08,789 --> 00:20:06,070 yeah let me start and karina you can 587 00:20:10,150 --> 00:20:08,799 fill in details 588 00:20:12,390 --> 00:20:10,160 let's see the first question the funny 589 00:20:15,669 --> 00:20:12,400 taste yeah we got we heard the same 590 00:20:18,230 --> 00:20:15,679 reports uh luca reported that 591 00:20:20,230 --> 00:20:18,240 he tried some of the water thinking 592 00:20:21,750 --> 00:20:20,240 initially that it may be the source was 593 00:20:23,430 --> 00:20:21,760 from the drink bag 594 00:20:25,430 --> 00:20:23,440 and it tasted funny 595 00:20:27,029 --> 00:20:25,440 which also pinpoints a couple of things 596 00:20:29,270 --> 00:20:27,039 and karina brought up you know we will 597 00:20:31,430 --> 00:20:29,280 also worry about the uh 598 00:20:33,750 --> 00:20:31,440 the anti-fog that we put on the the 599 00:20:35,430 --> 00:20:33,760 visors that has a it's basically like 600 00:20:37,510 --> 00:20:35,440 dish soap kind of stuff if you've ever 601 00:20:39,510 --> 00:20:37,520 gone diving you put dish soap on there 602 00:20:40,549 --> 00:20:39,520 and that has a weird funny taste also as 603 00:20:42,070 --> 00:20:40,559 you mentioned 604 00:20:43,669 --> 00:20:42,080 uh the 605 00:20:45,909 --> 00:20:43,679 garment the cooling system has a 606 00:20:47,110 --> 00:20:45,919 different taste and it has a iodine that 607 00:20:48,870 --> 00:20:47,120 runs through it 608 00:20:50,390 --> 00:20:48,880 to keep the bacteria from 609 00:20:51,909 --> 00:20:50,400 growing in the in the loop so there's a 610 00:20:54,070 --> 00:20:51,919 number of different sources and again we 611 00:20:56,310 --> 00:20:54,080 use that information 612 00:20:58,310 --> 00:20:56,320 to help us pinpoint where the source of 613 00:21:00,230 --> 00:20:58,320 this leak might be 614 00:21:01,430 --> 00:21:00,240 secondly you said if it's a pinpoint 615 00:21:02,950 --> 00:21:01,440 leak how would 616 00:21:05,590 --> 00:21:02,960 how would it end up 617 00:21:06,870 --> 00:21:05,600 up in the head region versus down in the 618 00:21:08,390 --> 00:21:06,880 the gloves 619 00:21:11,110 --> 00:21:08,400 uh if i understood your question 620 00:21:13,590 --> 00:21:11,120 correctly and why is that so 621 00:21:15,830 --> 00:21:13,600 again things tend in zero g to to kind 622 00:21:17,510 --> 00:21:15,840 of move around and bubble 623 00:21:20,070 --> 00:21:17,520 that certainly is a piece of information 624 00:21:23,029 --> 00:21:20,080 we learned through discussing with luca 625 00:21:24,390 --> 00:21:23,039 about where the water locations were 626 00:21:26,390 --> 00:21:24,400 that 627 00:21:28,710 --> 00:21:26,400 kind of helps us hone in on where 628 00:21:31,750 --> 00:21:28,720 potential areas of concern might be with 629 00:21:32,549 --> 00:21:31,760 the suit so yeah we're looking at all 630 00:21:36,789 --> 00:21:32,559 that 631 00:21:38,549 --> 00:21:36,799 the water started pooling in the back of 632 00:21:42,390 --> 00:21:38,559 his head and seemed to increase from 633 00:21:46,070 --> 00:21:44,149 in a radio call to mission control that 634 00:21:49,270 --> 00:21:46,080 uh his clothes his thermal garment was 635 00:21:51,270 --> 00:21:49,280 dry except for normal sweat 636 00:21:52,870 --> 00:21:51,280 i can answer that 637 00:21:54,950 --> 00:21:52,880 what that helps us to answer is there's 638 00:21:56,630 --> 00:21:54,960 a connector between the suit the hard 639 00:21:58,950 --> 00:21:56,640 upper torso of the suit and the cooling 640 00:22:00,630 --> 00:21:58,960 garment and it helps us to say that 641 00:22:02,470 --> 00:22:00,640 there was not a direct leak at that 642 00:22:04,470 --> 00:22:02,480 location because it's kind of right at 643 00:22:05,750 --> 00:22:04,480 your belly button so that was that was 644 00:22:07,590 --> 00:22:05,760 very helpful information that luca 645 00:22:09,590 --> 00:22:07,600 provided 646 00:22:11,669 --> 00:22:09,600 okay and lastly was this the same suit 647 00:22:13,830 --> 00:22:11,679 used last week 648 00:22:15,510 --> 00:22:13,840 yes it was 649 00:22:18,310 --> 00:22:15,520 okay thank you very much thank you leo 650 00:22:20,630 --> 00:22:18,320 enright with irish television 651 00:22:23,190 --> 00:22:20,640 thanks very much josh i just wondered at 652 00:22:25,110 --> 00:22:23,200 what stage were the europeans involved 653 00:22:27,350 --> 00:22:25,120 in all this this was 654 00:22:30,149 --> 00:22:27,360 uh just about the most serious incident 655 00:22:32,470 --> 00:22:30,159 i can remember uh involving a 656 00:22:36,070 --> 00:22:32,480 spacewalking astronaut at one stage it 657 00:22:38,070 --> 00:22:36,080 seemed uh luca was functionally blind 658 00:22:40,630 --> 00:22:38,080 deaf and mute 659 00:22:42,549 --> 00:22:40,640 for various reasons because of the water 660 00:22:45,110 --> 00:22:42,559 so at what stage were the europeans 661 00:22:47,590 --> 00:22:45,120 consulted in in these emergencies at 662 00:22:49,909 --> 00:22:47,600 what stage are international partners 663 00:22:51,350 --> 00:22:49,919 consulted what is the status of the 664 00:22:52,950 --> 00:22:51,360 international partnership at that 665 00:22:55,430 --> 00:22:52,960 particular point 666 00:23:00,390 -->

far as international 670 00:23:11,830 --> 00:23:08,960 partnership yeah of course luca being 671 00:23:16,310 --> 00:23:11,840 the the first italian space walker 672 00:23:20,310 --> 00:23:18,549 the esa team relies on us 673 00:23:22,470 --> 00:23:20,320 here in houston as the eva experts and 674 00:23:24,230 --> 00:23:22,480 to handle these kind of situations and 675 00:23:26,310 --> 00:23:24,240 that's also part of the foundation of 676 00:23:28,149 --> 00:23:26,320 how the station program has been set 677 00:23:29,510 --> 00:23:28,159 with the partnership that we we provide 678 00:23:32,390 --> 00:23:29,520 the integration 679 00:23:35,029 --> 00:23:32,400 and the emergency response 680 00:23:37,029 --> 00:23:35,039 their teams are always plugged in 681 00:23:38,710 --> 00:23:37,039 and their control centers are part of 682 00:23:40,230 --> 00:23:38,720 our entire 683 00:23:42,310 --> 00:23:40,240 global team so they're aware of 684 00:23:44,070 --> 00:23:42,320 everything that's happening and we do 685 00:23:47,190 --> 00:23:44,080 keep them apprised as things are going 686 00:23:49,510 --> 00:23:47,200 along and following the eva once luca 687 00:23:51,190 --> 00:23:49,520 was safely back inside and some of the 688 00:23:52,789 --> 00:23:51,200 conferences that we've had with the uh 689 00:23:54,870 --> 00:23:52,799 the eva team 690 00:23:57,110 --> 00:23:54,880 we have involved the uh 691 00:23:59,110 --> 00:23:57,120 isa representatives here 692 00:24:01,029 --> 00:23:59,120 uh in the discussion so that they're 693 00:24:02,549 --> 00:24:01,039 aware of what we're doing and what 694 00:24:05,830 --> 00:24:02,559 things we're considering and any of the 695 00:24:07,270 --> 00:24:05,840 concerns that we've come up against 696 00:24:08,950 --> 00:24:07,280 and 697 00:24:10,630 --> 00:24:08,960 as far as a 698 00:24:12,630 --> 00:24:10,640 mission from a mission management team 699 00:24:14,870 --> 00:24:12,640 perspective issa is a member of the 700 00:24:17,909 --> 00:24:14,880 mission management team and and 701 00:24:20,630 --> 00:24:17,919 i spoke uh with our local 702 00:24:23,190 --> 00:24:20,640 representative from isa shortly after 703 00:24:24,710 --> 00:24:23,200 the crew got back in 704 00:24:26,470 --> 00:24:24,720 and gave them 705 00:24:28,470 --> 00:24:26,480 the most up-to-date information that we 706 00:24:30,870 --> 00:24:28,480 we had on the incident and what our 707 00:24:32,470 --> 00:24:30,880 forward steps were and as david said as 708 00:24:34,549 --> 00:24:32,480 we worked this afternoon through some of 709 00:24:36,390 --> 00:24:34,559 our technical meetings we've uh 710 00:24:38,549 --> 00:24:36,400 we've had that that same level of 711 00:24:41,350 --> 00:24:38,559 participation at the technical level 712 00:24:42,710 --> 00:24:41,360 with the with members of the esa team so 713 00:24:44,710 --> 00:24:42,720 and they'll continue to be part of that 714 00:24:46,870 --> 00:24:44,720 going forward and 715 00:24:48,630 --> 00:24:46,880 as well uh their their medical teams 716 00:24:50,710 --> 00:24:48,640 will continue to do the same role that 717 00:24:53,510 --> 00:24:50,720 they have been in terms of of uh 718 00:24:56,549 --> 00:24:53,520 maintaining uh uh status on on lucas 719 00:25:02,310 --> 00:24:59,669 and josh if i might ask just a up which 720 00:25:04,310 --> 00:25:02,320 is rather more lighthearted 721 00:25:06,470 --> 00:25:04,320 and that is to do with a sequence where 722 00:25:08,950 --> 00:25:06,480 the astronauts at the early stages of 723 00:25:10,630 --> 00:25:08,960 the emergency paused 724 00:25:13,110 --> 00:25:10,640 and they did what i imagined they 725 00:25:15,909 --> 00:25:13,120 practiced for doing later in the eva 726 00:25:19,669 --> 00:25:15,919 they started taking personal photographs 727 00:25:22,310 --> 00:25:19,679 of luca and he started flipping cards on 728 00:25:23,990 --> 00:25:22,320 his wrist which appeared to be perhaps 729 00:25:26,149 --> 00:25:24,000 family photographs 730 00:25:28,630 --> 00:25:26,159 and some paintings or something of that 731 00:25:30,789 --> 00:25:28,640 sort i wondered if anyone on the panel 732 00:25:32,950 --> 00:25:30,799 knew what was going on there i realized 733 00:25:34,950 --> 00:25:32,960 it wasn't part of the 734 00:25:36,789 --> 00:25:34,960 to do with this story but i'm curious as 735 00:25:39,430 --> 00:25:36,799 to what was going on 736 00:25:41,669 --> 00:25:39,440 i know that is the uh the crew 737 00:25:43,430 --> 00:25:41,679 um gave us a shout out on the ground 738 00:25:45,269 --> 00:25:43,440 they they have on their cuff checklist 739 00:25:46,950 --> 00:25:45,279 some extra pages and and we did send 740 00:25:48,710 --> 00:25:46,960 them up some special 741 00:25:51,269 --> 00:25:48,720 pages that they can tape on there with 742 00:25:52,950 --> 00:25:51,279 details about um the procedures that 743 00:25:55,510 --> 00:25:52,960 they were doing today and they added 744 00:25:57,269 --> 00:25:55,520 some extra pages of their own accord and 745 00:25:59,430 --> 00:25:57,279 said thanks to the team on the ground 746 00:26:02,070 --> 00:25:59,440 for the eva so that was a really nice 747 00:26:03,669 --> 00:26:02,080 gesture on their part 748 00:26:08,950 --> 00:26:03,679 all right thanks leo let's go to miriam 749 00:26:12,789 --> 00:26:11,029 hi um thank you for doing this i 750 00:26:14,710 --> 00:26:12,799 actually am curious 751 00:26:17,269 --> 00:26:14,720 about um 752 00:26:20,470 --> 00:26:17,279 where this kind of incident uh might 753 00:26:23,430 --> 00:26:20,480 rank uh with other spacewalk incidents i 754 00:26:27,190 --> 00:26:23,440 mean it it was the second shortest 755 00:26:29,110 --> 00:26:27,200 um in in history but i'm curious is 756 00:26:31,190 --> 00:26:29,120 is this considered a particularly 757 00:26:33,029 --> 00:26:31,200 dangerous incident because i remember 758 00:26:34,950 --> 00:26:33,039 that same moment where they were taking 759 00:26:36,870 --> 00:26:34,960 photos of each other too so it seemed as 760 00:26:38,549 --> 00:26:36,880 if it was pretty light-hearted uh 761 00:26:40,149 --> 00:26:38,559 through the course of 762 00:26:42,070 --> 00:26:40,159 the um 763 00:26:43,029 --> 00:26:42,080 of the space block but but yeah where 764 00:26:47,110 --> 00:26:43,039 does this 765 00:26:54,070 --> 00:26:47,120 uh 766 00:26:58,950 --> 00:26:56,870 well look at karina 767 00:27:01,510 --> 00:26:58,960 i would say today was certainly a very 768 00:27:03,510 --> 00:27:01,520 serious issue we have had evas be cut 769 00:27:06,390 --> 00:27:03,520 short for other things that 770 00:27:08,470 --> 00:27:06,400 can ultimately be serious as well carbon 771 00:27:10,390 --> 00:27:08,480 dioxide 772 00:27:11,110 --> 00:27:10,400 levels rising being one of them and we 773 00:27:12,630 --> 00:27:11,120 do 774 00:27:14,630 --> 00:27:12,640 watch all those things 775 00:27:17,029 --> 00:27:14,640 closely on the ground so that we 776 00:27:19,029 --> 00:27:17,039 get the crew back inside 777 00:27:22,149 --> 00:27:19,039 before things get 778 00:27:26,070 --> 00:27:22,950 okay 779 00:27:28,549 --> 00:27:26,080 uh let's go to irene klotz with reuters 780 00:27:30,789 --> 00:27:28,559 hi thanks very much um 781 00:27:34,630 --> 00:27:30,799 i have a i have two questions the first 782 00:27:35,510 --> 00:27:34,640 is um just before parmitano reported the 783 00:27:38,390 --> 00:27:35,520 uh 784 00:27:40,870 --> 00:27:38,400 the water issue in his helmet he was 785 00:27:42,950 --> 00:27:40,880 wedged um reported that he was wedged 786 00:27:45,110 --> 00:27:42,960 between modules and maybe that sounded a 787 00:27:47,269 --> 00:27:45,120 lot worse than it is could someone 788 00:27:49,430 --> 00:27:47,279 please explain what was going on and if 789 00:27:51,350 --> 00:27:49,440 it's possible at all that the suit was 790 00:27:54,149 --> 00:27:51,360 damaged at that time 791 00:27:55,269 --> 00:27:54,159 and then the second question is if there 792 00:27:58,590 --> 00:27:55,279 were any 793 00:27:59,990 --> 00:27:58,600 precautionary medical um 794 00:28:02,230 --> 00:28:00,000 [Music] 795 00:28:04,310 --> 00:28:02,240 protocols or anything that he's been 796 00:28:06,389 --> 00:28:04,320 asked to do thanks 797 00:28:08,789 --> 00:28:06,399 i can answer the first question um we 798 00:28:10,710 --> 00:28:08,799 specifically asked him some questions he 799 00:28:13,190 --> 00:28:10,720 was in a work site that's fairly tight 800 00:28:15,269 --> 00:28:13,200 and there is a heat exchanger in that 801 00:28:17,190 --> 00:28:15,279 area as well and we were asking him some 802 00:28:19,269 --> 00:28:17,200 questions about 803 00:28:21,430 --> 00:28:19,279 the reach into that area so that we can 804 00:28:23,190 --> 00:28:21,440 verify that against our training 805 00:28:25,510 --> 00:28:23,200 mock-ups on the ground and make sure we 806 00:28:27,190 --> 00:28:25,520 understand what the 807 00:28:28,549 --> 00:28:27,200 difficulties would be of performing a 808 00:28:29,510 --> 00:28:28,559 heat exchanger 809 00:28:33,590 --> 00:28:29,520 in 810 00:28:36,630 --> 00:28:33,600 that was planned he was not 811 00:28:39,909 --> 00:28:36,640 wedged um in there by accident he was 812 00:28:43,029 --> 00:28:41,909 yeah i'll address the second part as far 813 00:28:44,870 --> 00:28:43,039 as the 814 00:28:47,350 --> 00:28:44,880 the surgeons i what i failed to mention 815 00:28:48,470 --> 00:28:47,360 earlier uh the gentleman from ireland 816 00:28:50,870 --> 00:28:48,480 asked about the international 817 00:28:53,590 --> 00:28:50,880 participation involvement uh we do have 818 00:28:57,110 --> 00:28:53,600 resident here just for this set of evas 819 00:28:59,909 --> 00:28:57,120 uh some of the surgeon team from esa 820 00:29:01,430 --> 00:28:59,919 and so after the first eva as well as 821 00:29:04,389 --> 00:29:01,440 following this when we arranged for them 822 00:29:05,990 --> 00:29:04,399 to talk uh to luca to assess his health 823 00:29:08,310 --> 00:29:06,000 and uh they 824 00:29:12,710 --> 00:29:08,320 they've not reported any any ill effects 825 00:29:19,909 --> 00:29:16,070 um so if he ingested any any water that 826 00:29:22,070 --> 00:29:19,919 was um painted from the liquid cooling 827 00:29:23,590 --> 00:29:22,080 garment or the 828 00:29:25,029 --> 00:29:23,600 film on the 829 00:29:27,590 --> 00:29:25,039 inside the helmet that you had mentioned 830 00:29:28,549 --> 00:29:27,600 earlier there are no health implications 831 00:29:31,190 --> 00:29:28,559 for that 832 00:29:33,510 --> 00:29:31,200 yeah no that we're aware of 833 00:29:35,190 --> 00:29:33,520 thank you okay thanks irene let's go to 834 00:29:41,029 --> 00:29:35,200 elizabeth barber with christian science 835 00:29:44,789 --> 00:29:43,430 elizabeth are you there 836 00:29:51,750 --> 00:29:44,799 all right let's move along to carrie 837 00:29:57,110 --> 00:29:54,310 all right marcia dunn associated press 838 00:29:59,269 --> 00:29:57,120 hi can you hear me yeah oh good um i 839 00:30:01,590 --> 00:29:59,279 have a couple of questions 840 00:30:03,830 --> 00:30:01,600 um if the two water sources are either 841 00:30:06,710 --> 00:30:03,840 the water bag or the garment cooling 842 00:30:08,630 --> 00:30:06,720 system the garment or the tanks doesn't 843 00:30:10,630 --> 00:30:08,640 this mean the garment or the tanks are 844 00:30:14,070 --> 00:30:10,640 the number one suspects in at this point 845 00:30:18,710 --> 00:30:15,909 i would say that the 846 00:30:20,830 --> 00:30:18,720 likelihood of the leak coming from the 847 00:30:23,350 --> 00:30:20,840 drink bag is 848 00:30:24,710 --> 00:30:23,360 um pretty low at this point given what 849 00:30:26,230 --> 00:30:24,720 the crew has 850 00:30:28,230 --> 00:30:26,240 told us but 851 00:30:30,389 --> 00:30:28,240 like we always do i'm sure you've seen 852 00:30:32,070 --> 00:30:30,399 these press conferences before when we 853 00:30:33,830 --> 00:30:32,080 have different things that don't go as 854 00:30:35,190 --> 00:30:33,840 planned on orbit 855 00:30:36,789 --> 00:30:35,200 our whole 856 00:30:38,789 --> 00:30:36,799 spacewalk community will be working 857 00:30:40,470 --> 00:30:38,799 through a fault tree 858 00:30:42,310 --> 00:30:40,480 and checking off 859 00:30:45,990 --> 00:30:42,320 every possible source that we can think 860 00:30:51,510 --> 00:30:47,830 okay i have two more questions if i 861 00:30:54,310 --> 00:30:51,520 might i'm wondering um the risks um of 862 00:30:56,950 --> 00:30:54,320 all that water inside his helmet inside 863 00:30:58,710 --> 00:30:56,960 the entire suit actually um 864 00:31:01,830 --> 00:30:58,720 are there systems in there that could 865 00:31:03,510 --> 00:31:01,840 have if wet could have given him a shock 866 00:31:05,029 --> 00:31:03,520 and i'm wondering it might you know 867 00:31:08,710 --> 00:31:05,039 choking or drowning even have been a 868 00:31:10,710 --> 00:31:08,720 possibility if he'd had no relief 869 00:31:12,870 --> 00:31:10,720 so the choking or drowning is definitely 870 00:31:13,750 --> 00:31:12,880 a possibility 871 00:31:15,269 --> 00:31:13,760 there's 872 00:31:17,110 --> 00:31:15,279 very little in the way of electrical 873 00:31:19,350 --> 00:31:17,120 systems inside the suit on purpose 874 00:31:20,549 --> 00:31:19,360 because it is also a pure oxygen 875 00:31:22,389 --> 00:31:20,559 environment 876 00:31:25,669 --> 00:31:22,399 so the only systems inside the suit that 877 00:31:28,950 --> 00:31:25,679 are electrical is the com cap and the 878 00:31:31,350 --> 00:31:28,960 biomed sensors which are pretty low uh 879 00:31:33,990 --> 00:31:31,360 low voltage type systems 880 00:31:35,669 --> 00:31:34,000 thank you and my last question had to do 881 00:31:40,070 --> 00:31:35,679 with the the uh 882 00:31:41,990 --> 00:31:40,080 the test the tension the tension um 883 00:31:43,830 --> 00:31:42,000 in mission control if this was all 884 00:31:46,149 --> 00:31:43,840 happening especially as the problem 885 00:31:48,710 --> 00:31:46,159 seemed to mount and you couldn't see he 886 00:31:51,110 --> 00:31:48,720 couldn't hear he couldn't speak um was 887 00:31:53,350 --> 00:31:51,120 that scary i'm just wondering how would 888 00:31:55,029 --> 00:31:53,360 you characterize that it must have been 889 00:31:57,590 --> 00:31:55,039 some hairy moments for the flight 890 00:31:59,190 --> 00:31:57,600 controllers as well 891 00:32:02,630 --> 00:31:59,200 you know 892 00:32:04,470 --> 00:32:02,640 we train a lot of these things and we go 893 00:32:07,750 --> 00:32:04,480 through uh generic and then 894 00:32:10,070 --> 00:32:07,760 uh task specific simulations and we uh 895 00:32:13,110 --> 00:32:10,080 we always try to train uh some level of 896 00:32:15,669 --> 00:32:13,120 emergency and uh you get to where you 897 00:32:17,269 --> 00:32:15,679 are in our business whether you're the 898 00:32:20,070 --> 00:32:17,279 eva officer or anybody else in the 899 00:32:20,950 --> 00:32:20,080 control room uh by uh having proven that 900 00:32:23,269 --> 00:32:20,960 you can 901 00:32:24,950 --> 00:32:23,279 go through things and think clearly 902 00:32:27,430 --> 00:32:24,960 and kind of divorce yourself from the 903 00:32:28,630 --> 00:32:27,440 the actual moment at hand and just work 904 00:32:30,549 --> 00:32:28,640 through the way you've been trained work 905 00:32:31,990 --> 00:32:30,559 through your procedures and and that's 906 00:32:33,509 --> 00:32:32,000 kind of the way the team 907 00:32:35,669 --> 00:32:33,519 actually performed today they did a 908 00:32:38,789 --> 00:32:35,679 great job everyone responded 909 00:32:40,870 --> 00:32:38,799 very promptly very succinctly and we 910 00:32:42,389 --> 00:32:40,880 worked through understanding where we 911 00:32:43,269 --> 00:32:42,399 were and as soon as we got a good sense 912 00:32:45,350 --> 00:32:43,279 that 913 00:32:46,230 --> 00:32:45,360 from both chris and luca working as a 914 00:32:48,070 --> 00:32:46,240 team 915 00:32:51,430 --> 00:32:48,080 on board that the the water was 916 00:32:53,269 --> 00:32:51,440 increasing in volume in luca's helmet 917 00:32:55,590 --> 00:32:53,279 we immediately kicked into the 918 00:32:57,990 --> 00:32:55,600 terminated eva mode and everyone 919 00:33:00,310 --> 00:32:58,000 understood clearly what that meant and 920 00:33:02,549 --> 00:33:00,320 we got him back in the airlock expedited 921 00:33:07,590 --> 00:33:02,559 getting the suit and helmet off and got 922 00:33:11,509 --> 00:33:09,909 and so how big of a relief was it when 923 00:33:13,269 --> 00:33:11,519 he finally got the helmet off i mean was 924 00:33:15,029 --> 00:33:13,279 there an audible sight going through the 925 00:33:16,310 --> 00:33:15,039 mission control tell me tell me how that 926 00:33:18,549 --> 00:33:16,320 moment was 927 00:33:19,590 --> 00:33:18,559 you know for me you know anytime you do 928 00:33:21,029 --> 00:33:19,600 anything 929 00:33:23,029 --> 00:33:21,039 like eva or whatever it's always 930 00:33:25,190 --> 00:33:23,039 dangerous there's always a great sigh of 931 00:33:27,509 --> 00:33:25,200 relief inwardly when the crew's back 932 00:33:28,950 --> 00:33:27,519 safe inside period 933 00:33:31,750 --> 00:33:28,960 honestly 934 00:33:33,669 --> 00:33:31,760 going through the moment at the time 935 00:33:35,190 --> 00:33:33,679 a lot of it was starting to think about 936 00:33:36,310 --> 00:33:35,200 why why did this happen what could have 937 00:33:38,389 --> 00:33:36,320 gone wrong 938 00:33:39,350 --> 00:33:38,399 and what do we what data do we need to 939 00:33:40,149 --> 00:33:39,360 gather 940 00:33:47,909 --> 00:33:40,159 uh 941 00:33:49,029 --> 00:33:47,919 we lose the sense of the detail so those 942 00:33:51,029 --> 00:33:49,039 are the first things that we start 943 00:33:53,830 --> 00:33:51,039 thinking about and there's time later on 944 00:33:56,230 --> 00:33:53,840 to sigh relief 945 00:33:59,750 --> 00:33:56,240 thank you okay marcia smith with space 946 00:34:04,950 --> 00:34:01,909 yes i had a question about how long it 947 00:34:07,190 --> 00:34:04,960 took again for the uh crew to get back 948 00:34:09,510 --> 00:34:07,200 into the airlock and you had mentioned 949 00:34:11,589 --> 00:34:09,520 that there were even more expedited 950 00:34:13,270 --> 00:34:11,599 procedures that you could have used so 951 00:34:14,629 --> 00:34:13,280 would you confirm it was 25 minutes 952 00:34:16,550 --> 00:34:14,639 before they got back to the airlock and 953 00:34:17,510 --> 00:34:16,560 then 10 minutes before they were either 954 00:34:19,589 --> 00:34:17,520 suits 955 00:34:21,589 --> 00:34:19,599 is that about right and and how much 956 00:34:24,550 --> 00:34:21,599 more quickly could they have gotten back 957 00:34:26,470 --> 00:34:24,560 in if you'd realize how serious it was 958 00:34:28,230 --> 00:34:26,480 yeah i don't have my detailed timeline 959 00:34:29,750 --> 00:34:28,240 with me but it was about 20 minutes from 960 00:34:32,710 --> 00:34:29,760 the moment we 961 00:34:35,030 --> 00:34:32,720 declared uh let's terminate the eva 962 00:34:36,710 --> 00:34:35,040 until chris was back in the airlock with 963 00:34:37,990 --> 00:34:36,720 the hatch closed luca was back in the 964 00:34:40,790 --> 00:34:38,000 airlock 965 00:34:42,869 --> 00:34:40,800 much sooner than that 966 00:34:45,270 --> 00:34:42,879 again i i don't have the specifics with 967 00:34:48,629 --> 00:34:45,280 me about how much quicker the 968 00:34:50,629 --> 00:34:48,639 expedited or the emergency repress 969 00:34:52,629 --> 00:34:50,639 scenario works out i don't know if you 970 00:34:55,270 --> 00:34:52,639 remember that the 971 00:34:57,109 --> 00:34:55,280 the equalization valve in the hatch can 972 00:34:58,790 --> 00:34:57,119 repressurize the air lock very very 973 00:34:59,670 --> 00:34:58,800 quickly i don't i don't have a number 974 00:35:01,109 --> 00:34:59,680 but 975 00:35:03,430 --> 00:35:01,119 if we had needed to turn that to the 976 00:35:06,310 --> 00:35:03,440 emergency position and we had actually 977 00:35:08,150 --> 00:35:06,320 given karen on board the heads up and 978 00:35:09,510 --> 00:35:08,160 the eba crew as well to be ready and 979 00:35:11,510 --> 00:35:09,520 that they could do that if they needed 980 00:35:12,950 --> 00:35:11,520 to they just turn it to a new position 981 00:35:14,710 --> 00:35:12,960 and it would repressurize the airlock 982 00:35:16,950 --> 00:35:14,720 very quickly and the other thing that we 983 00:35:20,230 --> 00:35:16,960 always practice with all of our eva 984 00:35:21,829 --> 00:35:20,240 crews is a crew rescue scenario so if 985 00:35:23,430 --> 00:35:21,839 luca had needed additional help getting 986 00:35:24,870 --> 00:35:23,440 back in the airlock 987 00:35:27,510 --> 00:35:24,880 the crew would have been perfectly 988 00:35:30,790 --> 00:35:27,520 prepared for chris to come help and get 989 00:35:32,790 --> 00:35:30,800 him back in the air lock any quicker 990 00:35:35,030 --> 00:35:32,800 thank you and could you also go over 991 00:35:40,630 --> 00:35:35,040 again how many functional spacesuits 992 00:35:45,349 --> 00:35:43,270 so i know that we have two because 993 00:35:48,069 --> 00:35:45,359 we had 994 00:35:49,829 --> 00:35:48,079 each of the two crew members can size up 995 00:35:52,069 --> 00:35:49,839 to the next size we that's something 996 00:35:53,270 --> 00:35:52,079 that we check before we do evas to 997 00:35:55,190 --> 00:35:53,280 understand what our backup suit 998 00:35:56,390 --> 00:35:55,200 capability is in case for instance we 999 00:35:58,710 --> 00:35:56,400 had a problem with the suit while we 1000 00:36:01,829 --> 00:35:58,720 were checking it out before these evas 1001 00:36:04,069 --> 00:36:01,839 so we do have at least two and we've got 1002 00:36:05,510 --> 00:36:04,079 a number of other parts on board and i 1003 00:36:06,870 --> 00:36:05,520 haven't counted up how many of those 1004 00:36:09,109 --> 00:36:06,880 parts could be put together into 1005 00:36:11,430 --> 00:36:09,119 additional suits 1006 00:36:13,510 --> 00:36:11,440 okay thank you all right amina khan with 1007 00:36:15,510 --> 00:36:13,520 los angeles times 1008 00:36:18,390 --> 00:36:15,520 hi um thank you for for taking my 1009 00:36:21,430 --> 00:36:18,400 questions i just have a couple um of the 1010 00:36:23,109 --> 00:36:21,440 one to 1.5 liters how much of that was 1011 00:36:24,630 --> 00:36:23,119 in the helmet and how much it was in the 1012 00:36:27,190 --> 00:36:24,640 suit you may have touched upon this a 1013 00:36:28,950 --> 00:36:27,200 little bit already but where exactly was 1014 00:36:32,470 --> 00:36:28,960 the water in the in the suit not the 1015 00:36:36,870 --> 00:36:35,030 i would say the majority of the water 1016 00:36:38,710 --> 00:36:36,880 that they reported was in the helmet you 1017 00:36:41,349 --> 00:36:38,720 know obviously some of it got absorbed 1018 00:36:43,030 --> 00:36:41,359 in the the calm cap the the snoopy cap 1019 00:36:44,550 --> 00:36:43,040 that you see the crew wear 1020 00:36:46,470 --> 00:36:44,560 um 1021 00:36:47,829 --> 00:36:46,480 that's that's really the main place that 1022 00:36:49,670 --> 00:36:47,839 they reported that water had been 1023 00:36:52,829 --> 00:36:49,680 absorbed um 1024 00:36:54,790 --> 00:36:52,839 so i'd say the most of it was in the 1025 00:36:57,190 --> 00:36:54,800 helmet okay 1026 00:36:59,750 --> 00:36:57,200 and have there been any other incidents 1027 00:37:02,310 --> 00:36:59,760 of of damage to just i mean what's the 1028 00:37:04,630 --> 00:37:02,320 normal sort of wear and tear or or sort 1029 00:37:08,069 --> 00:37:04,640 of accidental malfunctions with tooth 1030 00:37:13,430 --> 00:37:09,589 we have not seen 1031 00:37:15,030 --> 00:37:13,440 a situation like this before um 1032 00:37:17,270 --> 00:37:15,040 you know we've had a smattering of other 1033 00:37:19,430 --> 00:37:17,280 things for instance 1034 00:37:22,470 --> 00:37:19,440 co2 sensors as it's been mentioned 1035 00:37:24,710 --> 00:37:22,480 before those are susceptible to water 1036 00:37:26,710 --> 00:37:24,720 in the ventilation loop moisture in the 1037 00:37:30,069 --> 00:37:26,720 ventilation loop or humidity 1038 00:37:31,910 --> 00:37:30,079 we've seen that a few different times 1039 00:37:34,550 --> 00:37:31,920 but overall i would have to say that our 1040 00:37:36,950 --> 00:37:34,560 suits are very robust they're they're 1041 00:37:40,150 --> 00:37:36,960 well designed and we don't very often 1042 00:37:45,430 --> 00:37:43,910 thank you okay bill harwood with cbs 1043 00:37:47,109 --> 00:37:45,440 hey thanks guys making sure you can hear 1044 00:37:49,030 --> 00:37:47,119 me yeah we can hear you 1045 00:37:50,710 --> 00:37:49,040 thanks um you know i just wanted to 1046 00:37:52,230 --> 00:37:50,720 parse the answer to a couple of these 1047 00:37:53,829 --> 00:37:52,240 earlier questions about 1048 00:37:55,270 --> 00:37:53,839 the situation luke would've been i mean 1049 00:37:57,109 --> 00:37:55,280 is this a case where 1050 00:37:58,710 --> 00:37:57,119 you ordered an early termination because 1051 00:38:00,870 --> 00:37:58,720 you wanted to protect against the 1052 00:38:05,190 --> 00:38:00,880 possibility of him being in real trouble 1053 00:38:08,630 --> 00:38:07,349 it it was clear that he was having 1054 00:38:10,230 --> 00:38:08,640 trouble we were definitely in a 1055 00:38:11,349 --> 00:38:10,240 situation where 1056 00:38:12,870 --> 00:38:11,359 um 1057 00:38:15,349 --> 00:38:12,880 we weren't expecting to be you know we 1058 00:38:17,190 --> 00:38:15,359 don't expect any water to be in the uh 1059 00:38:19,510 --> 00:38:17,200 above and beyond just normal sweating 1060 00:38:21,270 --> 00:38:19,520 inside the the helmet and when he 1061 00:38:23,670 --> 00:38:21,280 started reporting that it was 1062 00:38:24,950 --> 00:38:23,680 accumulating around his ears that's the 1063 00:38:27,510 --> 00:38:24,960 point at which we said you know we are 1064 00:38:29,270 --> 00:38:27,520 not comfortable doing anything else 1065 00:38:32,310 --> 00:38:29,280 for the rest of the eda i wouldn't i 1066 00:38:33,910 --> 00:38:32,320 wouldn't want my team to press forward 1067 00:38:35,910 --> 00:38:33,920 or have luca press forward trying to do 1068 00:38:37,829 --> 00:38:35,920 any tasks where we couldn't guarantee 1069 00:38:39,510 --> 00:38:37,839 that he could hear us clearly or 1070 00:38:41,829 --> 00:38:39,520 understand what we were telling him so 1071 00:38:43,670 --> 00:38:41,839 it was that point that we said this is a 1072 00:38:45,670 --> 00:38:43,680 good good place and a good reason to 1073 00:38:46,870 --> 00:38:45,680 terminate the eva 1074 00:38:48,710 --> 00:38:46,880 certainly when he got back to the 1075 00:38:50,710 --> 00:38:48,720 airlock the water accumulation started 1076 00:38:53,270 --> 00:38:50,720 to increase and so we knew we had made 1077 00:38:54,550 --> 00:38:53,280 the right decision 1078 00:38:55,510 --> 00:38:54,560 thanks and one more quick along those 1079 00:38:57,109 --> 00:38:55,520 lines 1080 00:38:58,630 --> 00:38:57,119 water in the helmet 1081 00:39:00,230 --> 00:38:58,640 i'm trying to picture that fishbowl 1082 00:39:01,670 --> 00:39:00,240 thing you were describing earlier with 1083 00:39:03,349 --> 00:39:01,680 without gravity 1084 00:39:05,190 --> 00:39:03,359 and it sounds like the real threat would 1085 00:39:06,390 --> 00:39:05,200 be starting to cough and you'd have a 1086 00:39:09,030 --> 00:39:06,400 hard time with that and then that could 1087 00:39:10,870 --> 00:39:09,040 get to be something worse um 1088 00:39:14,069 --> 00:39:10,880 is that kind of the threat you face if 1089 00:39:15,990 --> 00:39:14,079 you have too much water in the helmet 1090 00:39:18,470 --> 00:39:16,000 i'd say yes that's that's a correct 1091 00:39:19,990 --> 00:39:18,480 assessment of it um and you know if it's 1092 00:39:22,550 --> 00:39:20,000 just a little bit obviously you cough 1093 00:39:24,310 --> 00:39:22,560 you can expel that similar to how you do 1094 00:39:26,390 --> 00:39:24,320 here on earth but like i was describing 1095 00:39:28,150 --> 00:39:26,400 earlier in zero gravity the water tends 1096 00:39:30,550 --> 00:39:28,160 to wanna to 1097 00:39:32,310 --> 00:39:30,560 pool in just a big glob 1098 00:39:35,750 --> 00:39:32,320 and there's some interesting videos 1099 00:39:37,349 --> 00:39:35,760 probably available on youtube that um 1100 00:39:39,510 --> 00:39:37,359 i believe it was 1101 00:39:41,190 --> 00:39:39,520 chris hadfield did somebody asked him 1102 00:39:42,870 --> 00:39:41,200 can you cry in space and so he did a 1103 00:39:44,550 --> 00:39:42,880 little bit of experiment with a water 1104 00:39:45,750 --> 00:39:44,560 bag and he basically squirted water in 1105 00:39:47,750 --> 00:39:45,760 his eye and you can see it just becomes 1106 00:39:53,510 --> 00:39:47,760 this big glob of water in his eye it 1107 00:39:57,349 --> 00:39:55,510 okay one more quick one for me to follow 1108 00:39:58,630 --> 00:39:57,359 up marcia smith's question you had the 1109 00:39:59,990 --> 00:39:58,640 two suits you used today and i guess 1110 00:40:02,230 --> 00:40:00,000 what you're thinking is you have enough 1111 00:40:04,150 --> 00:40:02,240 spare parts you could possibly assemble 1112 00:40:06,630 --> 00:40:04,160 a third or do you have two backups i was 1113 00:40:07,430 --> 00:40:06,640 confused we have two full backups that 1114 00:40:08,950 --> 00:40:07,440 were 1115 00:40:10,950 --> 00:40:08,960 would have been ready to go today if we 1116 00:40:12,710 --> 00:40:10,960 had needed them during some of the 1117 00:40:14,150 --> 00:40:12,720 preparation work for these evas so we do 1118 00:40:16,710 --> 00:40:14,160 have two full backups and then 1119 00:40:18,230 --> 00:40:16,720 additional parts on top of that 1120 00:40:19,589 --> 00:40:18,240 thank you very much 1121 00:40:23,270 --> 00:40:19,599 okay thanks bill let's go to todd 1122 00:40:26,790 --> 00:40:25,270 uh thanks very much can you hear me yeah 1123 00:40:28,630 --> 00:40:26,800 we can 1124 00:40:30,910 --> 00:40:28,640 uh great um 1125 00:40:32,630 --> 00:40:30,920 this was uh the 1126 00:40:35,030 --> 00:40:32,640 171st 1127 00:40:38,230 --> 00:40:35,040 eva since assembly and maintenance of 1128 00:40:38,950 --> 00:40:38,240 the station began in late 1998 1129 00:40:40,790 --> 00:40:38,960 and 1130 00:40:43,109 --> 00:40:40,800 i'm wondering what this incident says 1131 00:40:45,670 --> 00:40:43,119 about the fact that you guys have been 1132 00:40:48,950 --> 00:40:45,680 able to uh pull off this 1133 00:40:50,069 --> 00:40:48,960 assembly uh and all of the other work 1134 00:40:54,550 --> 00:40:50,079 without 1135 00:40:59,030 --> 00:40:57,270 well i think it just uh it's just more 1136 00:41:01,190 --> 00:40:59,040 is a testament to the 1137 00:41:03,510 --> 00:41:01,200 to the uh the hardware that that gets 1138 00:41:04,550 --> 00:41:03,520 produced it gets gets flown to orbit and 1139 00:41:06,790 --> 00:41:04,560 the uh 1140 00:41:08,790 --> 00:41:06,800 and uh again along the way we've had our 1141 00:41:10,630 --> 00:41:08,800 challenges as karina said you know we've 1142 00:41:12,870 --> 00:41:10,640 had some problems with co2 sensors but 1143 00:41:15,589 --> 00:41:12,880 the team understands what to do when we 1144 00:41:17,270 --> 00:41:15,599 have those problems they're not uh 1145 00:41:19,349 --> 00:41:17,280 you know they're not life-threatening 1146 00:41:20,790 --> 00:41:19,359 when you manage them properly and so the 1147 00:41:23,190 --> 00:41:20,800 team has figured out how to manage your 1148 00:41:25,510 --> 00:41:23,200 way through those uh but the the 1149 00:41:28,150 --> 00:41:25,520 robustness of the hardware that that has 1150 00:41:30,309 --> 00:41:28,160 has come out of the eva project has been 1151 00:41:31,829 --> 00:41:30,319 been very good through the years and and 1152 00:41:35,190 --> 00:41:31,839 as you said we've done 1153 00:41:36,630 --> 00:41:35,200 a lot of ebas and we've had a 1154 00:41:38,950 --> 00:41:36,640 you know very good performance in the 1155 00:41:40,630 --> 00:41:38,960 airlock and so 1156 00:41:43,030 --> 00:41:40,640 again we'll go figure out what happened 1157 00:41:45,109 --> 00:41:43,040 in this instance and uh and we'll uh 1158 00:41:51,829 --> 00:41:45,119 we'll get back up and get ready to go to 1159 00:41:56,550 --> 00:41:53,510 thanks um 1160 00:41:59,109 --> 00:41:56,560 and uh i also wondered 1161 00:42:03,030 --> 00:41:59,119 you know what you would um 1162 00:42:04,470 --> 00:42:03,040 or david would say about the risks that 1163 00:42:06,790 --> 00:42:04,480 are involved with 1164 00:42:09,270 --> 00:42:06,800 space walking work just in a general 1165 00:42:11,670 --> 00:42:09,280 sense um i mean you guys mentioned that 1166 00:42:13,990 --> 00:42:11,680 this is part of the business of 1167 00:42:17,510 --> 00:42:14,000 operating a space station but i'm not 1168 00:42:20,790 --> 00:42:17,520 sure the public understands exactly uh 1169 00:42:22,630 --> 00:42:20,800 how much risk there is involved here and 1170 00:42:26,550 --> 00:42:22,640 i'm wondering if you could characterize 1171 00:42:30,790 --> 00:42:28,630 well let's see if i can sum that up in a 1172 00:42:33,109 --> 00:42:30,800 couple of seconds the i i can tell you 1173 00:42:35,829 --> 00:42:33,119 personally i've gotten a a much greater 1174 00:42:38,950 --> 00:42:35,839 appreciation of what goes into 1175 00:42:40,150 --> 00:42:38,960 preparing and conducting an eva 1176 00:42:42,230 --> 00:42:40,160 and i've been in the flight director 1177 00:42:45,030 --> 00:42:42,240 office for about seven years 1178 00:42:47,990 --> 00:42:45,040 and getting deep involved in this there 1179 00:42:49,670 --> 00:42:48,000 there are many many factors and you know 1180 00:42:51,990 --> 00:42:49,680 not to say this lightly but the the 1181 00:42:53,349 --> 00:42:52,000 devil is in the details absolutely and 1182 00:42:56,470 --> 00:42:53,359 and the folks 1183 00:43:00,150 --> 00:42:56,480 um in the eva project the the eva 1184 00:43:02,630 --> 00:43:00,160 operations team spend a lot of time 1185 00:43:04,790 --> 00:43:02,640 going through the details 1186 00:43:07,190 --> 00:43:04,800 whether it's procedures training the 1187 00:43:09,030 --> 00:43:07,200 hardware the maintenance of the hardware 1188 00:43:11,109 --> 00:43:09,040 there are a lot of aspects to this you 1189 00:43:13,190 --> 00:43:11,119 have to take into consideration 1190 00:43:15,190 --> 00:43:13,200 you've got to consider 1191 00:43:16,950 --> 00:43:15,200 temperatures outside on the different 1192 00:43:18,150 --> 00:43:16,960 modules and where the crew is going you 1193 00:43:20,870 --> 00:43:18,160 have to consider 1194 00:43:22,150 --> 00:43:20,880 how they get from point a to point b 1195 00:43:23,510 --> 00:43:22,160 you want to make sure they're tethered 1196 00:43:24,950 --> 00:43:23,520 properly 1197 00:43:26,829 --> 00:43:24,960 that all their equipment is tethered 1198 00:43:28,950 --> 00:43:26,839 properly 1199 00:43:31,270 --> 00:43:28,960 micrometeoroids you're always worried 1200 00:43:32,630 --> 00:43:31,280 about your procedures to deal with you 1201 00:43:34,710 --> 00:43:32,640 know the 1202 00:43:36,390 --> 00:43:34,720 unexpected and you know 1203 00:43:38,069 --> 00:43:36,400 hit of a micrometeoroid or something 1204 00:43:40,069 --> 00:43:38,079 that punctures the suit we worry about 1205 00:43:42,390 --> 00:43:40,079 gloves 1206 00:43:43,750 --> 00:43:42,400 we worry about 1207 00:43:45,510 --> 00:43:43,760 things floating away and not getting 1208 00:43:47,589 --> 00:43:45,520 away from us being able to have leverage 1209 00:43:49,270 --> 00:43:47,599 at the work sites so you can 1210 00:43:50,790 --> 00:43:49,280 you can get your task done 1211 00:43:52,950 --> 00:43:50,800 in a good manner and everything is 1212 00:43:55,589 --> 00:43:52,960 optimized for a six and a half hour 1213 00:43:56,790 --> 00:43:55,599 period of time outside and you're in a 1214 00:43:58,950 --> 00:43:56,800 very limited 1215 00:44:01,109 --> 00:43:58,960 mini spacesuit or a mini space station 1216 00:44:03,430 --> 00:44:01,119 that's going around outside 1217 00:44:04,710 --> 00:44:03,440 that's got limited consumables 1218 00:44:06,950 --> 00:44:04,720 so you got to get a lot done in a short 1219 00:44:09,030 --> 00:44:06,960 period of time and get back in safely so 1220 00:44:10,470 --> 00:44:09,040 there's a lot that goes into it i'm 1221 00:44:12,470 --> 00:44:10,480 certainly much more appreciative of 1222 00:44:13,990 --> 00:44:12,480 what's involved and 1223 00:44:16,790 --> 00:44:14,000 that's why you know as kenny mentioned 1224 00:44:19,589 --> 00:44:16,800 we don't take evas lightly at all and 1225 00:44:21,589 --> 00:44:19,599 everyone that goes out the door 1226 00:44:23,510 --> 00:44:21,599 we try to do our best to meet the 1227 00:44:25,030 --> 00:44:23,520 requirements but when the crew is back 1228 00:44:28,550 --> 00:44:25,040 in at the end of the day that's that's 1229 00:44:32,550 --> 00:44:30,230 all right thanks let's go to alan boyle 1230 00:44:34,950 --> 00:44:32,560 msnbc 1231 00:44:36,870 --> 00:44:34,960 hi thank you uh i just had a couple of 1232 00:44:40,230 --> 00:44:36,880 follow-up questions about the rate of 1233 00:44:42,230 --> 00:44:40,240 the accumulation of water uh it that's 1234 00:44:43,829 --> 00:44:42,240 just that it was 1235 00:44:46,309 --> 00:44:43,839 actually a leak in the system rather 1236 00:44:49,430 --> 00:44:46,319 than just a normal accumulation of water 1237 00:44:52,870 --> 00:44:49,440 and how much time do you think you had 1238 00:44:56,950 --> 00:44:52,880 left just judging by the rate of how the 1239 00:45:01,430 --> 00:44:59,510 it was definitely a leak in the system 1240 00:45:02,309 --> 00:45:01,440 this was this was not a normal amount of 1241 00:45:04,790 --> 00:45:02,319 water 1242 00:45:08,790 --> 00:45:04,800 and i i really couldn't quantify 1243 00:45:14,950 --> 00:45:11,910 but uh it definitely was accumulating at 1244 00:45:17,829 --> 00:45:14,960 a pretty fast rate uh what did it seem 1245 00:45:20,390 --> 00:45:17,839 fast to you uh were you surprised by 1246 00:45:25,510 --> 00:45:20,400 finding how much more water there was uh 1247 00:45:28,710 --> 00:45:27,430 um 1248 00:45:30,710 --> 00:45:28,720 i don't know that i would say i was 1249 00:45:32,470 --> 00:45:30,720 surprised um we knew that there was 1250 00:45:34,470 --> 00:45:32,480 going to be a a 1251 00:45:36,390 --> 00:45:34,480 good quantity of water and to be honest 1252 00:45:38,790 --> 00:45:36,400 i hadn't thought about what the 1253 00:45:41,670 --> 00:45:38,800 number was going to be 1254 00:45:46,309 --> 00:45:43,750 okay thanks okay thanks alan do we have 1255 00:45:47,430 --> 00:45:46,319 any followers here back in houston all 1256 00:45:49,030 --> 00:45:47,440 right that's going to wrap it up for
