1 00:00:06,800 --> 00:00:02,840 good afternoon and welcome today's 2 00:00:08,660 --> 00:00:06,810 expedition 32 post spacewalk briefing 3 00:00:10,790 --> 00:00:08,670 today we have with us International 4 00:00:13,759 --> 00:00:10,800 Space Station program manager Mike SEF 5 00:00:15,589 --> 00:00:13,769 rodini advanced ice the flight director 6 00:00:18,109 --> 00:00:15,599 in charge of the spacewalk today and 7 00:00:19,970 --> 00:00:18,119 Keith Johnson a lead spacewalk officer 8 00:00:21,349 --> 00:00:19,980 for today's activities we'll start off 9 00:00:24,200 --> 00:00:21,359 with some opening statements and they'll 10 00:00:26,210 --> 00:00:24,210 move on to your questions well good 11 00:00:28,189 --> 00:00:26,220 afternoon I never thought I'd be saying 12 00:00:29,990 --> 00:00:28,199 this but I've never been so happy to 13 00:00:33,620 --> 00:00:30,000 have seven of eight power channels 14 00:00:35,389 --> 00:00:33,630 onboard ISS as I am today and I won't go 15 00:00:37,040 --> 00:00:35,399 through all the details of the EBA I'll 16 00:00:40,430 --> 00:00:37,050 leave that to Eddie and Keith since they 17 00:00:42,709 --> 00:00:40,440 they live through it but we do have as 18 00:00:46,069 --> 00:00:42,719 everyone knows we've got the NBS you one 19 00:00:49,040 --> 00:00:46,079 installed and activated its it's acting 20 00:00:51,830 --> 00:00:49,050 very well and over the next couple of 21 00:00:54,979 --> 00:00:51,840 days we'll integrate all of the 22 00:00:57,529 --> 00:00:54,989 components back in that that mvsu feeds 23 00:01:00,349 --> 00:00:57,539 so we get more closer to a nominal 24 00:01:02,060 --> 00:01:00,359 config in addition that the team was 25 00:01:04,700 --> 00:01:02,070 able to take the time to change out the 26 00:01:07,190 --> 00:01:04,710 SSR ms boom camera which put us in a 27 00:01:10,190 --> 00:01:07,200 really good configuration for all the 28 00:01:12,310 --> 00:01:10,200 operations we do utilizing the arm while 29 00:01:16,550 --> 00:01:12,320 it was difficult to live without the 30 00:01:19,190 --> 00:01:16,560 this boom camera we can and and we're 31 00:01:22,219 --> 00:01:19,200 prepared to do that if we had to but 32 00:01:24,580 --> 00:01:22,229 today's EBA went as good as you could 33 00:01:27,080 --> 00:01:24,590 hope for and once we have to be MBS you 34 00:01:29,899 --> 00:01:27,090 installed the crew and the ground team 35 00:01:32,179 --> 00:01:29,909 decided they they have the time to go 36 00:01:33,920 --> 00:01:32,189 ahead and get the boom camper replace so 37 00:01:36,679 --> 00:01:33,930 we're in good shape the EBA went very 38 00:01:38,270 --> 00:01:36,689 well I'll talk a little bit about the 39 00:01:41,719 --> 00:01:38,280 future and then hand it to these guys to 40 00:01:43,850 --> 00:01:41,729 tell you more of the details so with the 41 00:01:45,679 --> 00:01:43,860 EBA that we had to do today we really 42 00:01:48,170 --> 00:01:45,689 couldn't squeeze in the HTV departure 43 00:01:51,889 --> 00:01:48,180 which was originally planned for for 44 00:01:54,620 --> 00:01:51,899 tomorrow in there in between the HTTP 45 00:01:59,060 --> 00:01:54,630 departure and the Soyuz departure we had 46 00:02:01,429 --> 00:01:59,070 a reboost planned to really it's for 47 00:02:03,440 --> 00:02:01,439 phasing for future vehicles it would 48 00:02:05,870 --> 00:02:03,450 tweak the landing a little bit but that 49 00:02:09,169 --> 00:02:05,880 wasn't mandatory but in working with the 50 00:02:12,559 --> 00:02:09,179 rest of the partners we've decided that 51 00:02:13,730 --> 00:02:12,569 the plan is as follows we will we will 52 00:02:17,900 --> 00:02:13,740 plan to have h 53 00:02:20,330 --> 00:02:17,910 depart on the 12th will do a reboost to 54 00:02:22,760 --> 00:02:20,340 tweak the phasing of the orbit on the 55 00:02:25,040 --> 00:02:22,770 fourteenth and then the soy of 30 so 56 00:02:27,650 --> 00:02:25,050 users will depart on time on the 57 00:02:30,140 --> 00:02:27,660 sixteenth and and that then puts 58 00:02:32,270 --> 00:02:30,150 everything in play to go ahead and have 59 00:02:34,270 --> 00:02:32,280 the ATV depart on time which i think is 60 00:02:36,800 --> 00:02:34,280 currently the twenty-fifth of September 61 00:02:40,210 --> 00:02:36,810 so hats off to the team they did a 62 00:02:43,940 --> 00:02:40,220 fantastic job this is a very challenging 63 00:02:45,920 --> 00:02:43,950 issue that took a lot of a lot of 64 00:02:47,960 --> 00:02:45,930 thinking about what do you have in your 65 00:02:51,080 --> 00:02:47,970 your list of tools and not necessarily 66 00:02:53,150 --> 00:02:51,090 tools on orbit that you can use to get 67 00:02:56,600 --> 00:02:53,160 yourself in a good posture to install 68 00:02:59,240 --> 00:02:56,610 this bolt as it turned out the bolt post 69 00:03:03,190 --> 00:02:59,250 did had some some rough threads in it 70 00:03:05,900 --> 00:03:03,200 and since we don't have on orbit a 71 00:03:07,430 --> 00:03:05,910 tapping device per se we had to come up 72 00:03:08,930 --> 00:03:07,440 with tools kind of cleaning out as best 73 00:03:11,390 --> 00:03:08,940 we could and then and then run this 74 00:03:13,850 --> 00:03:11,400 other bolt in but the team did a really 75 00:03:16,700 --> 00:03:13,860 great job the crew did a fantastic job 76 00:03:18,410 --> 00:03:16,710 outside today and and as a result of 77 00:03:20,450 --> 00:03:18,420 that we're back in in really good shape 78 00:03:24,860 --> 00:03:20,460 on orbit and so with that I'll hand it 79 00:03:26,600 --> 00:03:24,870 over to add thank you sir i'll start 80 00:03:28,580 --> 00:03:26,610 with the the end of today obviously i 81 00:03:32,890 --> 00:03:28,590 getting MBS you one installed and 82 00:03:36,680 --> 00:03:32,900 activated doing that successfully is a 83 00:03:37,970 --> 00:03:36,690 broad team across several organizations 84 00:03:40,220 --> 00:03:37,980 throughout the program and across the 85 00:03:42,680 --> 00:03:40,230 partnership to to make that all happen 86 00:03:44,480 --> 00:03:42,690 and i'm extremely proud and impressed 87 00:03:46,760 --> 00:03:44,490 with all the work of all the people that 88 00:03:50,000 --> 00:03:46,770 were involved in putting this together 89 00:03:51,710 --> 00:03:50,010 not only the EV a team but as they're 90 00:03:53,720 --> 00:03:51,720 the ones that are out in front pulling 91 00:03:55,910 --> 00:03:53,730 this together for the crew but all of 92 00:03:57,580 --> 00:03:55,920 the different flight control disciplines 93 00:04:00,530 --> 00:03:57,590 that are involved all the engineers 94 00:04:02,750 --> 00:04:00,540 analysts the folks at Kennedy Space 95 00:04:05,390 --> 00:04:02,760 Center that actually installed the MBS 96 00:04:06,800 --> 00:04:05,400 you into s0 before it launched at the 97 00:04:08,480 --> 00:04:06,810 press conference we had last week mr. 98 00:04:10,280 --> 00:04:08,490 Sabatini talked about going back and 99 00:04:12,740 --> 00:04:10,290 pulling paper on the actual initial 100 00:04:14,510 --> 00:04:12,750 installations we did that we talked to 101 00:04:16,039 --> 00:04:14,520 everybody we possibly could to 102 00:04:18,410 --> 00:04:16,049 understand what was going on and that 103 00:04:19,970 --> 00:04:18,420 paid off here today in the end I'll talk 104 00:04:22,010 --> 00:04:19,980 briefly about what's happened over the 105 00:04:23,900 --> 00:04:22,020 last six days if you can believe it it's 106 00:04:24,620 --> 00:04:23,910 today's only the sixth day after the end 107 00:04:28,490 --> 00:04:24,630 of the 108 00:04:32,210 --> 00:04:28,500 third-longest a VA in US history last 109 00:04:34,700 --> 00:04:32,220 Thursday since that time even friday 110 00:04:37,670 --> 00:04:34,710 morning we had a skeleton plan of what 111 00:04:40,190 --> 00:04:37,680 we would do on a EV a that turned out to 112 00:04:42,110 --> 00:04:40,200 be today we came with a bunch of 113 00:04:43,370 --> 00:04:42,120 questions first obviously what happened 114 00:04:45,980 --> 00:04:43,380 and wanted to understand as best we 115 00:04:47,750 --> 00:04:45,990 could what happened last Thursday and 116 00:04:50,570 --> 00:04:47,760 then we went from those questions to try 117 00:04:52,670 --> 00:04:50,580 to in broad terms say what needs to be 118 00:04:55,370 --> 00:04:52,680 done to make us most successful on doing 119 00:04:58,160 --> 00:04:55,380 it again so of course that meant go take 120 00:04:59,390 --> 00:04:58,170 a look at the failed MBS you the the MBS 121 00:05:00,830 --> 00:04:59,400 you we have been trying to install and 122 00:05:03,230 --> 00:05:00,840 see if it had been damaged if there is 123 00:05:05,360 --> 00:05:03,240 anything on that MBS you that might tell 124 00:05:06,980 --> 00:05:05,370 us some clues about what had happened we 125 00:05:09,290 --> 00:05:06,990 also needed to clean that up and get it 126 00:05:11,780 --> 00:05:09,300 ready for installation go inspect the 127 00:05:14,480 --> 00:05:11,790 cold plate on the s0 work site where the 128 00:05:16,970 --> 00:05:14,490 NBS you gets installed make sure see if 129 00:05:18,290 --> 00:05:16,980 there are any smoking guns out there to 130 00:05:20,060 --> 00:05:18,300 show us what had happened but then also 131 00:05:22,340 --> 00:05:20,070 get that all cleaned up and ready for an 132 00:05:24,410 --> 00:05:22,350 installation task from that point the 133 00:05:27,620 --> 00:05:24,420 engineers and all the various flight 134 00:05:29,150 --> 00:05:27,630 controllers went from those questions to 135 00:05:30,530 --> 00:05:29,160 finding ways to get answers to those 136 00:05:32,330 --> 00:05:30,540 questions so of course we looked at 137 00:05:35,390 --> 00:05:32,340 paperwork we looked at previous tasks 138 00:05:38,180 --> 00:05:35,400 that had similar types of installations 139 00:05:40,550 --> 00:05:38,190 for example the battery charge discharge 140 00:05:42,200 --> 00:05:40,560 units the BC to use we've installed some 141 00:05:44,480 --> 00:05:42,210 of those in our past and they have a 142 00:05:46,220 --> 00:05:44,490 similar configuration we went talked to 143 00:05:49,070 --> 00:05:46,230 all the people involved with those 144 00:05:50,840 --> 00:05:49,080 activities to learn what we could we 145 00:05:52,700 --> 00:05:50,850 also like mr. suffered any mentioned we 146 00:05:54,500 --> 00:05:52,710 went and invented new tools that we 147 00:05:57,260 --> 00:05:54,510 could take outside to help us clean and 148 00:06:01,250 --> 00:05:57,270 chase the threads in the posts of the 149 00:06:03,770 --> 00:06:01,260 SEO cold plate to blow out any debris to 150 00:06:05,990 --> 00:06:03,780 look for damage and to make sure that we 151 00:06:08,600 --> 00:06:06,000 fully understood and could correct the 152 00:06:10,790 --> 00:06:08,610 best we could the situation there at s0 153 00:06:12,410 --> 00:06:10,800 we also had several very long 154 00:06:14,780 --> 00:06:12,420 discussions with all of our engineering 155 00:06:16,880 --> 00:06:14,790 counterparts to take the questions as 156 00:06:18,740 --> 00:06:16,890 far deep as we possibly could what if we 157 00:06:20,840 --> 00:06:18,750 find such and such out at the work site 158 00:06:22,880 --> 00:06:20,850 what are we going to do if this method 159 00:06:24,680 --> 00:06:22,890 doesn't work what's the next step so 160 00:06:26,270 --> 00:06:24,690 we've really completely developed as 161 00:06:29,120 --> 00:06:26,280 much we could as we could what we call 162 00:06:32,120 --> 00:06:29,130 the crib sheet or the what do you do if 163 00:06:35,360 --> 00:06:32,130 this happens paperwork and that went 164 00:06:37,820 --> 00:06:35,370 very smoothly developing that was a long 165 00:06:38,159 --> 00:06:37,830 process several meetings went into that 166 00:06:41,580 --> 00:06:38,169 but 167 00:06:43,110 --> 00:06:41,590 today's success shows the the results of 168 00:06:44,399 --> 00:06:43,120 all those all those meetings and how 169 00:06:46,200 --> 00:06:44,409 fruitful they were we had a great 170 00:06:47,969 --> 00:06:46,210 documentation we didn't have to stray 171 00:06:50,519 --> 00:06:47,979 from it and it enabled us to be 172 00:06:52,890 --> 00:06:50,529 successful today so the we call it a 173 00:06:55,649 --> 00:06:52,900 team for effort and it's because we were 174 00:06:59,070 --> 00:06:55,659 pulling out a separate team to go focus 175 00:07:00,959 --> 00:06:59,080 on all these it really was a amazing 176 00:07:02,879 --> 00:07:00,969 experience to be a part of and to watch 177 00:07:05,249 --> 00:07:02,889 as this entire team came together with 178 00:07:07,469 --> 00:07:05,259 its resolve to fix the singular issue 179 00:07:08,969 --> 00:07:07,479 and then we did so with enough time left 180 00:07:11,399 --> 00:07:08,979 that we could go pick up one remaining 181 00:07:12,929 --> 00:07:11,409 scheduled test from last week CBA and 182 00:07:14,279 --> 00:07:12,939 that was replacing the boom camera so 183 00:07:16,649 --> 00:07:14,289 I'm glad we could get that done as well 184 00:07:18,360 --> 00:07:16,659 and over the course of these two epa's 185 00:07:21,300 --> 00:07:18,370 we were able to get all of our primary 186 00:07:23,670 --> 00:07:21,310 objectives for the EBA 18 accomplished 187 00:07:26,459 --> 00:07:23,680 so I'm very very happy with the success 188 00:07:31,140 --> 00:07:26,469 the EBA and I like Keitha go into any 189 00:07:33,899 --> 00:07:31,150 more details he wants to thanks it let's 190 00:07:37,679 --> 00:07:33,909 see so today zva was six hours and 28 191 00:07:41,369 --> 00:07:37,689 minutes which puts sunny at 44 hours and 192 00:07:44,639 --> 00:07:41,379 two minutes of total EV a duration puts 193 00:07:46,829 --> 00:07:44,649 her 11th in the u.s. standings and and 194 00:07:50,969 --> 00:07:46,839 she is of course the the number one 195 00:07:52,260 --> 00:07:50,979 female duration for four evaa so that's 196 00:07:55,649 --> 00:07:52,270 kind of cool and we let her know that 197 00:07:57,629 --> 00:07:55,659 during the VA she slept it off as and 198 00:07:58,769 --> 00:07:57,639 said I'm just out here doing a job and 199 00:08:01,230 --> 00:07:58,779 I'm in the right place at the right time 200 00:08:03,600 --> 00:08:01,240 so that's a as a wonderful attitude to 201 00:08:06,659 --> 00:08:03,610 have to know that she's out there to do 202 00:08:09,469 --> 00:08:06,669 her job aki that was his second dva 203 00:08:12,719 --> 00:08:09,479 makes his total 14 hours and 45 minutes 204 00:08:16,019 --> 00:08:12,729 he is the leading japanese astronaut he 205 00:08:19,350 --> 00:08:16,029 surpassed to cowboy who had 12 hours and 206 00:08:22,200 --> 00:08:19,360 43 minutes we went out the door with an 207 00:08:25,290 --> 00:08:22,210 off nominal suit configuration from the 208 00:08:28,800 --> 00:08:25,300 VA last week we had a problem with the 209 00:08:32,550 --> 00:08:28,810 cooling on aki suit and because of that 210 00:08:35,279 --> 00:08:32,560 both crew members had to shift suits aki 211 00:08:39,449 --> 00:08:35,289 went out in sunny suits which was 212 00:08:42,329 --> 00:08:39,459 resized for him and sunny went out in a 213 00:08:44,670 --> 00:08:42,339 large heart upper torso which is an off 214 00:08:46,680 --> 00:08:44,680 nominal size but she had practiced in it 215 00:08:49,780 --> 00:08:46,690 before and she didn't have any 216 00:08:53,620 --> 00:08:49,790 complaints and and stuck a head 217 00:08:56,020 --> 00:08:53,630 with the plan so I'd mentioned a lot of 218 00:08:58,960 --> 00:08:56,030 the the work that went into getting 219 00:09:00,640 --> 00:08:58,970 ready for this e VA and I have to say I 220 00:09:02,980 --> 00:09:00,650 had many people come up to me and asked 221 00:09:05,980 --> 00:09:02,990 me what I what I thought the odds were 222 00:09:08,590 --> 00:09:05,990 of installing the MBS you under these 223 00:09:10,960 --> 00:09:08,600 conditions and and really the best that 224 00:09:13,440 --> 00:09:10,970 you could do is is plan for getting the 225 00:09:15,370 --> 00:09:13,450 Box in but then also plan for all of the 226 00:09:17,250 --> 00:09:15,380 multiple things that you would have to 227 00:09:19,750 --> 00:09:17,260 do if we had to bring that box inside 228 00:09:23,080 --> 00:09:19,760 mr. suffered any asked us to look at 229 00:09:24,940 --> 00:09:23,090 that several months ago with the the 230 00:09:28,270 --> 00:09:24,950 failed box that we took out because 231 00:09:30,990 --> 00:09:28,280 their plans to potentially change out 232 00:09:34,330 --> 00:09:31,000 one of the the plates inside of that the 233 00:09:36,460 --> 00:09:34,340 cards and so we did have a chance to 234 00:09:40,180 --> 00:09:36,470 look at how well that n BSU fits inside 235 00:09:42,160 --> 00:09:40,190 of the airlock along with other bags and 236 00:09:45,000 --> 00:09:42,170 because of that we came up with a 237 00:09:48,010 --> 00:09:45,010 configuration that if we needed to bring 238 00:09:50,230 --> 00:09:48,020 everything back inside with us along 239 00:09:52,740 --> 00:09:50,240 with both crew members we we had a safe 240 00:09:56,140 --> 00:09:52,750 configuration so we had to plan for that 241 00:09:59,500 --> 00:09:56,150 and during the the week between the 242 00:10:01,450 --> 00:09:59,510 failure and the CVA today as ed 243 00:10:05,740 --> 00:10:01,460 mentioned we had teams going off 244 00:10:10,480 --> 00:10:05,750 developing many many tools to make our 245 00:10:13,570 --> 00:10:10,490 jobs more highly successful one of the 246 00:10:16,020 --> 00:10:13,580 the tools that we developed we pulled 247 00:10:21,760 --> 00:10:16,030 out we have spare boxes that are inside 248 00:10:27,310 --> 00:10:21,770 Space Station that are the same bolting 249 00:10:29,650 --> 00:10:27,320 configuration as as the MBS you so in 250 00:10:34,120 --> 00:10:29,660 order to understand what could have been 251 00:10:36,220 --> 00:10:34,130 wrong with the bolt we scavenged the the 252 00:10:40,000 --> 00:10:36,230 bolting mechanism out of one of the 253 00:10:43,000 --> 00:10:40,010 boxes that was inside and developed what 254 00:10:45,220 --> 00:10:43,010 we used as a tapping tool that mr. 255 00:10:48,460 --> 00:10:45,230 suffered any mentioned this is a 256 00:10:52,390 --> 00:10:48,470 t-handle tool that the crew members use 257 00:10:55,360 --> 00:10:52,400 to restrain some of the the outer 258 00:10:59,260 --> 00:10:55,370 coating on space station it's a handling 259 00:11:02,200 --> 00:10:59,270 aid it's got a pin on one end and it fit 260 00:11:03,220 --> 00:11:02,210 nicely into just fortunately fit nicely 261 00:11:06,970 --> 00:11:03,230 into the 262 00:11:09,040 --> 00:11:06,980 mechanism and so we could develop a tool 263 00:11:11,260 --> 00:11:09,050 that allowed us to drive the bolt 264 00:11:13,870 --> 00:11:11,270 without the box around it so we could 265 00:11:16,960 --> 00:11:13,880 see just what it took to get a bolt 266 00:11:20,080 --> 00:11:16,970 installed we also had to put tether 267 00:11:22,420 --> 00:11:20,090 features on it and that allowed us to 268 00:11:25,810 --> 00:11:22,430 keep it safely secured during the 269 00:11:27,880 --> 00:11:25,820 operation well we knew that the torque 270 00:11:29,350 --> 00:11:27,890 was going to be a high running torque or 271 00:11:32,680 --> 00:11:29,360 we suspected that it was going to be 272 00:11:35,520 --> 00:11:32,690 fairly high this is about what a gloved 273 00:11:38,560 --> 00:11:35,530 hand could could do to turn this bolt 274 00:11:41,470 --> 00:11:38,570 and because the torque could go up from 275 00:11:44,680 --> 00:11:41,480 there we had to find a way to allow us 276 00:11:49,900 --> 00:11:44,690 to take this t-handle tool off and put 277 00:11:51,910 --> 00:11:49,910 another socket in place so the the guys 278 00:11:54,130 --> 00:11:51,920 on the ground came up with a really 279 00:11:58,570 --> 00:11:54,140 nifty method to cut this particular tool 280 00:12:02,290 --> 00:11:58,580 loose and then install a much larger 281 00:12:04,000 --> 00:12:02,300 handle that would then allow them to put 282 00:12:07,270 --> 00:12:04,010 quite a bit more torque into the bolt 283 00:12:09,940 --> 00:12:07,280 and this was a really good design and 284 00:12:11,320 --> 00:12:09,950 this worked out really well because the 285 00:12:13,270 --> 00:12:11,330 torque got to the point where neither 286 00:12:16,390 --> 00:12:13,280 sunny nor aki was able to do it with 287 00:12:18,580 --> 00:12:16,400 with the t-handle tool and it also 288 00:12:21,490 --> 00:12:18,590 allowed them to drive it both forward 289 00:12:24,760 --> 00:12:21,500 and backward when installing the bolt 290 00:12:27,430 --> 00:12:24,770 and that way they overcame the rough 291 00:12:30,630 --> 00:12:27,440 spots that mr. suffer dini mentioned by 292 00:12:33,730 --> 00:12:30,640 driving it through those those spots so 293 00:12:39,100 --> 00:12:33,740 we in the process lubricated the bolt 294 00:12:42,820 --> 00:12:39,110 with lubricant that we've used on orbit 295 00:12:47,200 --> 00:12:42,830 before this is the what we call the lube 296 00:12:52,950 --> 00:12:47,210 gun and it has breakout in it which is 297 00:12:56,530 --> 00:12:52,960 kind of a vacuum stabilized grease with 298 00:12:59,950 --> 00:12:56,540 some some particles in it that allow it 299 00:13:02,860 --> 00:12:59,960 to some graphite particles that at eight 300 00:13:04,450 --> 00:13:02,870 and lubrication we brought this gun out 301 00:13:09,430 --> 00:13:04,460 with us and fortunately we didn't have 302 00:13:11,710 --> 00:13:09,440 to use it the this in previous ivas 303 00:13:15,340 --> 00:13:11,720 we've used this gun to lubricate the 304 00:13:17,310 --> 00:13:15,350 solar alpha rotary joint and also the 305 00:13:19,890 --> 00:13:17,320 the end effector on the 306 00:13:23,490 --> 00:13:19,900 and other points were grapple fixtures 307 00:13:27,630 --> 00:13:23,500 on board space station so we had this on 308 00:13:30,030 --> 00:13:27,640 board we used it to squirt into midst 309 00:13:34,320 --> 00:13:30,040 that the crew members have for applying 310 00:13:36,540 --> 00:13:34,330 this this lubricant and with that they 311 00:13:39,480 --> 00:13:36,550 put some of their other tools that we we 312 00:13:43,530 --> 00:13:39,490 applied the lubricant to such as the 313 00:13:46,560 --> 00:13:43,540 bolt that I mentioned before and also an 314 00:13:51,000 --> 00:13:46,570 application tool that may seem familiar 315 00:13:53,310 --> 00:13:51,010 to people which is a toothbrush so while 316 00:13:55,110 --> 00:13:53,320 we were I VA the crew took this 317 00:13:57,870 --> 00:13:55,120 toothbrush attached it to another 318 00:14:02,340 --> 00:13:57,880 t-handle and then put it in the grease 319 00:14:05,070 --> 00:14:02,350 and prepared it to go EV a so the 320 00:14:07,590 --> 00:14:05,080 process the crew used once they got the 321 00:14:09,540 --> 00:14:07,600 the MBS you out and away from the 322 00:14:13,830 --> 00:14:09,550 stanchion and we knew that we had 323 00:14:18,000 --> 00:14:13,840 particles down inside the socket so they 324 00:14:19,740 --> 00:14:18,010 came outside with yet another tool that 325 00:14:23,310 --> 00:14:19,750 was developed by the ground team and 326 00:14:30,360 --> 00:14:23,320 this is a very interesting tool this is 327 00:14:34,700 --> 00:14:30,370 a piece of cable that has the end wires 328 00:14:37,680 --> 00:14:34,710 bent back to make a bit of a brush and 329 00:14:40,950 --> 00:14:37,690 they took this tool out with them to the 330 00:14:42,840 --> 00:14:40,960 work site it has on the end of it what 331 00:14:45,120 --> 00:14:42,850 we can attach the the pistol grip tool 332 00:14:49,580 --> 00:14:45,130 so they put the pistol grip tool on it 333 00:14:52,950 --> 00:14:49,590 and then drove it down into the socket 334 00:14:54,990 --> 00:14:52,960 and then back out again and in the 335 00:14:57,540 --> 00:14:55,000 process of doing that they liberated a 336 00:15:00,060 --> 00:14:57,550 lot of the extra material that that we 337 00:15:01,740 --> 00:15:00,070 suspect was binding the bolt and they 338 00:15:03,570 --> 00:15:01,750 also had a chance to kind of feel how 339 00:15:05,190 --> 00:15:03,580 stiff it was driving it in and then 340 00:15:07,590 --> 00:15:05,200 driving back out again so it gave him 341 00:15:08,790 --> 00:15:07,600 some appreciation for what they had in 342 00:15:11,760 --> 00:15:08,800 store for them when they were going to 343 00:15:13,770 --> 00:15:11,770 drive the bolt after that we took the 344 00:15:16,470 --> 00:15:13,780 gas the tool that you saw in the 345 00:15:18,540 --> 00:15:16,480 previous e VA which is a nitrogen 346 00:15:20,910 --> 00:15:18,550 canister attached to a little nozzle and 347 00:15:23,400 --> 00:15:20,920 they put it down in and they they 348 00:15:25,680 --> 00:15:23,410 bursted the nitrogen gas down in to get 349 00:15:29,730 --> 00:15:25,690 blow out the particulate that was down 350 00:15:30,660 --> 00:15:29,740 inside and then after that was done we 351 00:15:33,330 --> 00:15:30,670 took the 352 00:15:37,290 --> 00:15:33,340 brush that I mentioned and my little bag 353 00:15:41,130 --> 00:15:37,300 of tricks here and we used this covered 354 00:15:45,600 --> 00:15:41,140 with lubricant and drove it down in and 355 00:15:47,940 --> 00:15:45,610 then back out again and lubricated again 356 00:15:50,310 --> 00:15:47,950 the socket drove the bolt down in with 357 00:15:52,860 --> 00:15:50,320 the tools that I mentioned and after 358 00:15:55,170 --> 00:15:52,870 doing that back and forth several times 359 00:15:57,690 --> 00:15:55,180 to get past those points the crew 360 00:16:00,300 --> 00:15:57,700 members felt that it was time to install 361 00:16:03,210 --> 00:16:00,310 the box as we did on the ground and we 362 00:16:05,850 --> 00:16:03,220 put the MBS you in place and in this 363 00:16:08,310 --> 00:16:05,860 particular case you saw before we were 364 00:16:10,920 --> 00:16:08,320 using a torque multiplier and a PG t we 365 00:16:12,780 --> 00:16:10,930 decided that probably the best method 366 00:16:15,060 --> 00:16:12,790 for driving this bolt where you'd get 367 00:16:18,240 --> 00:16:15,070 the most feedback and you also have a 368 00:16:20,760 --> 00:16:18,250 good lever arm was using our EV a 369 00:16:22,680 --> 00:16:20,770 ratchet tool with the socket attached to 370 00:16:26,340 --> 00:16:22,690 it so the crew members put this into the 371 00:16:30,090 --> 00:16:26,350 bolt and it turns out that this time we 372 00:16:32,520 --> 00:16:30,100 also came up with some methods to get 373 00:16:34,350 --> 00:16:32,530 the Box in a neutral position which 374 00:16:36,660 --> 00:16:34,360 allowed them to drive the bolt much more 375 00:16:40,320 --> 00:16:36,670 easily than we saw on the previous e VA 376 00:16:43,050 --> 00:16:40,330 which proves successful and we didn't 377 00:16:45,750 --> 00:16:43,060 have any other issues during the EV a 378 00:16:48,120 --> 00:16:45,760 the suits ran very well and the crew 379 00:16:49,860 --> 00:16:48,130 members had a good fit and they're back 380 00:16:54,420 --> 00:16:49,870 inside right now getting ready for bed 381 00:16:55,890 --> 00:16:54,430 and we're very happy with the EBA ok 382 00:16:58,550 --> 00:16:55,900 we'll start out with questions here at 383 00:17:02,730 --> 00:16:58,560 the Johnson Space and are in Houston 384 00:17:04,680 --> 00:17:02,740 yeah sure if I have time for one so Mike 385 00:17:08,880 --> 00:17:04,690 what point did you breathe a sigh of 386 00:17:13,260 --> 00:17:08,890 relief today Oh Gina you always ask me 387 00:17:16,200 --> 00:17:13,270 these questions let's see I didn't sweat 388 00:17:18,000 --> 00:17:16,210 too much when the NBS you wouldn't go in 389 00:17:20,280 --> 00:17:18,010 because being down two channels wasn't 390 00:17:22,230 --> 00:17:20,290 too bad but the last few days every day 391 00:17:25,770 --> 00:17:22,240 as you were watching we lost to Pat 392 00:17:29,160 --> 00:17:25,780 another power Channel we lost a thermal 393 00:17:30,720 --> 00:17:29,170 loop at least briefly and node 3 and we 394 00:17:32,220 --> 00:17:30,730 had another hiccup that's evading me 395 00:17:35,070 --> 00:17:32,230 right this instant but we had a number 396 00:17:37,710 --> 00:17:35,080 of little gotchas come up we had a 397 00:17:41,670 --> 00:17:37,720 normal health flag on NBS you two over 398 00:17:44,140 --> 00:17:41,680 the course of a few days and so things 399 00:17:46,300 --> 00:17:44,150 seemed like they were adding up so 400 00:17:48,100 --> 00:17:46,310 once the NBS you went in that was nice 401 00:17:49,900 --> 00:17:48,110 but when they powered it up and said it 402 00:17:52,750 --> 00:17:49,910 was a healthy box then I started feel a 403 00:17:54,520 --> 00:17:52,760 little bit better and friend Keith when 404 00:17:59,260 --> 00:17:54,530 did the toothbrush come to play and 405 00:18:01,630 --> 00:17:59,270 whose bright idea was that well you know 406 00:18:03,850 --> 00:18:01,640 what I mean I would that I heard it come 407 00:18:05,590 --> 00:18:03,860 from two different directions so I I 408 00:18:07,660 --> 00:18:05,600 would like to say that at some point I 409 00:18:09,520 --> 00:18:07,670 suggested it and i don't want to take 410 00:18:11,140 --> 00:18:09,530 credit because someone else came in and 411 00:18:13,000 --> 00:18:11,150 said hey we just tried the the 412 00:18:15,130 --> 00:18:13,010 toothbrush over on the fixture and I 413 00:18:16,330 --> 00:18:15,140 thought it's someone hear me say that or 414 00:18:18,280 --> 00:18:16,340 did they come up with it on their own 415 00:18:20,440 --> 00:18:18,290 and and I have to say you know there are 416 00:18:22,450 --> 00:18:20,450 lots and lots of brilliant ideas that 417 00:18:24,760 --> 00:18:22,460 that come up with people and it's always 418 00:18:26,230 --> 00:18:24,770 those ones where you know you take 419 00:18:28,630 --> 00:18:26,240 something common that everybody 420 00:18:31,060 --> 00:18:28,640 understands and and use it in an off 421 00:18:33,640 --> 00:18:31,070 nominal situation that just really makes 422 00:18:36,430 --> 00:18:33,650 you appreciate where you work and what 423 00:18:38,440 --> 00:18:36,440 you do we were concerned that this 424 00:18:40,480 --> 00:18:38,450 wasn't going to pass thermal vacuum 425 00:18:43,150 --> 00:18:40,490 testing so as part of the whole 426 00:18:44,800 --> 00:18:43,160 preparation for the e VA and you know we 427 00:18:46,570 --> 00:18:44,810 send teams all over the place because we 428 00:18:49,630 --> 00:18:46,580 look at every every aspect of things 429 00:18:51,850 --> 00:18:49,640 that could go wrong or how you could get 430 00:18:53,410 --> 00:18:51,860 it stuck or cause more damage with the 431 00:18:56,890 --> 00:18:53,420 piece of hardware that you're taking out 432 00:18:58,840 --> 00:18:56,900 and then good so we did put this in a 433 00:19:00,130 --> 00:18:58,850 thermal vacuum chamber and found out 434 00:19:01,780 --> 00:19:00,140 that it could stand the high 435 00:19:03,310 --> 00:19:01,790 temperatures and low temperatures and 436 00:19:05,080 --> 00:19:03,320 we're still a little nervous about the 437 00:19:06,880 --> 00:19:05,090 the bristles or breaking off but the 438 00:19:12,040 --> 00:19:06,890 crew was very careful with it so we're 439 00:19:14,530 --> 00:19:12,050 very happy about that it was really 440 00:19:16,240 --> 00:19:14,540 amazing to watch the ingenuity of the 441 00:19:19,150 --> 00:19:16,250 engineers involved in the the flight 442 00:19:20,290 --> 00:19:19,160 controllers and they would come up with 443 00:19:22,240 --> 00:19:20,300 this idea of hey let's stick a 444 00:19:23,620 --> 00:19:22,250 toothbrush in there and from there it 445 00:19:25,150 --> 00:19:23,630 was like okay well if we're going to do 446 00:19:27,250 --> 00:19:25,160 that it has to have this it has to be 447 00:19:28,600 --> 00:19:27,260 long enough it has to be tether abul ask 448 00:19:31,510 --> 00:19:28,610 you something that a gloved hand can 449 00:19:33,550 --> 00:19:31,520 interact with we have to be able to to 450 00:19:35,080 --> 00:19:33,560 spin it and keep control of it and in 451 00:19:37,690 --> 00:19:35,090 the right away just a halt this wide 452 00:19:40,030 --> 00:19:37,700 variety of ingenious people oh well if 453 00:19:41,560 --> 00:19:40,040 we put this the tape on it for example 454 00:19:43,480 --> 00:19:41,570 that'll keep it all together and keep it 455 00:19:46,120 --> 00:19:43,490 within the thermal and we'll put this 456 00:19:48,370 --> 00:19:46,130 particular tool on it so it's got a 457 00:19:51,280 --> 00:19:48,380 tether point and it makes it the right 458 00:19:52,810 --> 00:19:51,290 size and then you know we would get go 459 00:19:54,670 --> 00:19:52,820 through a couple prototypes really 460 00:19:56,310 --> 00:19:54,680 quickly and go over to the mock-up 461 00:19:58,360 --> 00:19:56,320 facility and try it out and 462 00:19:59,500 --> 00:19:58,370 there you have it we have the tools that 463 00:20:03,400 --> 00:19:59,510 you see in front of you it was amazing 464 00:20:05,950 --> 00:20:03,410 to watch it all come together Robert 465 00:20:07,840 --> 00:20:05,960 problems collectspace.com so these 466 00:20:10,510 --> 00:20:07,850 makeshift tools now become part of the 467 00:20:12,910 --> 00:20:10,520 permanent spacewalkers arsenal or does 468 00:20:14,590 --> 00:20:12,920 it now inspire the team on earth to go 469 00:20:17,260 --> 00:20:14,600 formalize an actually build a tool that 470 00:20:22,060 --> 00:20:17,270 does the same job they launched on a 471 00:20:24,100 --> 00:20:22,070 future mission linear term at least they 472 00:20:26,140 --> 00:20:24,110 will certainly become what we consider 473 00:20:27,820 --> 00:20:26,150 to be hip pockets we certainly won't 474 00:20:30,820 --> 00:20:27,830 throw away the the good work that we've 475 00:20:32,590 --> 00:20:30,830 done to assemble these if we need them 476 00:20:35,830 --> 00:20:32,600 again my guess is that the crew will 477 00:20:37,030 --> 00:20:35,840 take and keep them somewhere staged on 478 00:20:39,640 --> 00:20:37,040 board the vehicle I don't believe we're 479 00:20:41,710 --> 00:20:39,650 going to build any more before we need 480 00:20:42,910 --> 00:20:41,720 them again I wouldn't be surprised 481 00:20:44,440 --> 00:20:42,920 though if there isn't a team that goes 482 00:20:46,540 --> 00:20:44,450 off and we're going to have a lot of 483 00:20:48,190 --> 00:20:46,550 post flight that goes on with this and 484 00:20:50,200 --> 00:20:48,200 make sure we truly understand what 485 00:20:52,360 --> 00:20:50,210 happened and how we should be postured 486 00:20:54,670 --> 00:20:52,370 and if we decide that this has 487 00:20:57,370 --> 00:20:54,680 applicability across a wide range it if 488 00:20:59,140 --> 00:20:57,380 not go build and fly new tools then 489 00:21:03,040 --> 00:20:59,150 certainly will consider ways to better 490 00:21:04,480 --> 00:21:03,050 our posture in case before it happens 491 00:21:08,050 --> 00:21:04,490 the next time even if it means just 492 00:21:11,110 --> 00:21:08,060 assembling something on board the these 493 00:21:13,420 --> 00:21:11,120 these boxes are very common so the 494 00:21:15,940 --> 00:21:13,430 batteries have this same to acne bolt 495 00:21:18,160 --> 00:21:15,950 solution the the mDM's that are 496 00:21:21,040 --> 00:21:18,170 installed have the in fact this bolt 497 00:21:23,190 --> 00:21:21,050 came from an MDM that's that stored 498 00:21:25,570 --> 00:21:23,200 inside that actually is for use outside 499 00:21:29,050 --> 00:21:25,580 so one of the things we all wished we 500 00:21:31,900 --> 00:21:29,060 had was a tap to follow the threads down 501 00:21:34,450 --> 00:21:31,910 in case they were buggered up and so 502 00:21:37,570 --> 00:21:34,460 that was already on our list in fact we 503 00:21:39,730 --> 00:21:37,580 were planning on flying that on the next 504 00:21:41,110 --> 00:21:39,740 SpaceX flight that was already in our 505 00:21:43,780 --> 00:21:41,120 plan in case other things didn't work 506 00:21:45,340 --> 00:21:43,790 out for so ed said you know you look at 507 00:21:47,530 --> 00:21:45,350 the things you wish you had on orbit 508 00:21:50,380 --> 00:21:47,540 that perhaps we'll do that job better 509 00:21:51,880 --> 00:21:50,390 and will probably think about that in 510 00:21:53,470 --> 00:21:51,890 terms of we have a lot of our use 511 00:21:55,360 --> 00:21:53,480 outside all of them have this same 512 00:21:58,120 --> 00:21:55,370 interface and what are the set of two 513 00:22:00,250 --> 00:21:58,130 tools the crew should have when they go 514 00:22:01,420 --> 00:22:00,260 out to this next one is just to see it 515 00:22:03,100 --> 00:22:01,430 and make sure that you don't have to 516 00:22:04,540 --> 00:22:03,110 come back inside you can do the things 517 00:22:06,269 --> 00:22:04,550 you know you need to do if the threads 518 00:22:09,299 --> 00:22:06,279 are our 519 00:22:12,299 --> 00:22:09,309 not acting right for you add to that 520 00:22:13,919 --> 00:22:12,309 that the tools that we use do in most 521 00:22:16,409 --> 00:22:13,929 cases we try to use ones that are 522 00:22:18,419 --> 00:22:16,419 already EV a certified so these do have 523 00:22:21,899 --> 00:22:18,429 a use for them and will probably d 524 00:22:23,459 --> 00:22:21,909 integrate the what we put together these 525 00:22:24,930 --> 00:22:23,469 are now covered with grease and 526 00:22:27,810 --> 00:22:24,940 particulate that we want to keep 527 00:22:30,810 --> 00:22:27,820 somewhat isolated so we'll take those 528 00:22:32,519 --> 00:22:30,820 probably out of the inventory but at 529 00:22:35,669 --> 00:22:32,529 least consider you know where they are 530 00:22:37,109 --> 00:22:35,679 for a future EBA I'm not sure which 531 00:22:38,369 --> 00:22:37,119 particular crew member the toothbrush 532 00:22:45,749 --> 00:22:38,379 came from but they're going to want it 533 00:22:47,369 --> 00:22:45,759 back so just a larger sense more than 534 00:22:50,820 --> 00:22:47,379 ten years into the station's life and 535 00:22:53,629 --> 00:22:50,830 165 spacewalks did you at all anticipate 536 00:22:56,549 --> 00:22:53,639 that bolts were gonna still be an issue 537 00:22:58,829 --> 00:22:56,559 this far into the program and what does 538 00:23:00,149 --> 00:22:58,839 it say for looking out you know towards 539 00:23:01,649 --> 00:23:00,159 the outers well you know we didn't 540 00:23:05,549 --> 00:23:01,659 really talk to you too much about what 541 00:23:08,639 --> 00:23:05,559 causes what causes this problem so 542 00:23:11,039 --> 00:23:08,649 during the EV a the the team got to the 543 00:23:13,950 --> 00:23:11,049 point where they were trying to use 544 00:23:17,039 --> 00:23:13,960 technique to get the Box down and this 545 00:23:18,749 --> 00:23:17,049 is not the first box like this we we did 546 00:23:22,049 --> 00:23:18,759 six batteries which have the same 547 00:23:24,359 --> 00:23:22,059 interface and and so really this was a 548 00:23:26,399 --> 00:23:24,369 combination of technique but that the 549 00:23:29,070 --> 00:23:26,409 bolts we found this particular bolt as 550 00:23:31,049 --> 00:23:29,080 you may have called what call it noticed 551 00:23:33,599 --> 00:23:31,059 watching the EBA this particular bolt 552 00:23:35,219 --> 00:23:33,609 about four turns in got stuck and we 553 00:23:37,769 --> 00:23:35,229 really couldn't get past about four 554 00:23:40,289 --> 00:23:37,779 turns during the the last dva and when 555 00:23:44,519 --> 00:23:40,299 we ran this bolt down we found this spot 556 00:23:46,109 --> 00:23:44,529 in this area so this doesn't have to do 557 00:23:47,399 --> 00:23:46,119 with how long it's been on orbit it 558 00:23:48,989 --> 00:23:47,409 really has to do with when we install 559 00:23:51,570 --> 00:23:48,999 them when we start and when we installed 560 00:23:53,969 --> 00:23:51,580 these particular NBS use and this one in 561 00:23:55,769 --> 00:23:53,979 particular because of the the face of 562 00:23:58,619 --> 00:23:55,779 the truss it's on I think I mentioned 563 00:24:01,049 --> 00:23:58,629 this before this really we didn't have 564 00:24:03,239 --> 00:24:01,059 we weren't able to rotate the s0 trust 565 00:24:05,369 --> 00:24:03,249 so the crews the ground crews had to get 566 00:24:08,190 --> 00:24:05,379 on scissor jack they lift up as high as 567 00:24:10,079 --> 00:24:08,200 it can to 220 pound oh are you in there 568 00:24:11,399 --> 00:24:10,089 in a 45 degree face facing up and 569 00:24:12,930 --> 00:24:11,409 they're trying to get it up here and 570 00:24:15,599 --> 00:24:12,940 then they're trying to torque it in 571 00:24:18,389 --> 00:24:15,609 wiglet and torque it so we're not 572 00:24:19,740 --> 00:24:18,399 completely surprised that that the the 573 00:24:21,890 --> 00:24:19,750 threads could be a little 574 00:24:24,900 --> 00:24:21,900 gummed up again you can't you can't 575 00:24:26,670 --> 00:24:24,910 cross thread and Acme bolt but but we 576 00:24:28,580 --> 00:24:26,680 think we called the bolt which is not an 577 00:24:32,370 --> 00:24:28,590 uncommon thing to have happen if you put 578 00:24:34,320 --> 00:24:32,380 a torque off-center torque on it while 579 00:24:36,750 --> 00:24:34,330 you're trying to to a torque the bolt 580 00:24:38,580 --> 00:24:36,760 down so so we believe just as a normal 581 00:24:40,200 --> 00:24:38,590 course of installing some of these or 582 00:24:42,330 --> 00:24:40,210 used particularly ones where we couldn't 583 00:24:44,190 --> 00:24:42,340 put the trust in a position where is 584 00:24:45,750 --> 00:24:44,200 easy to lower in case of the batteries 585 00:24:48,240 --> 00:24:45,760 we always rotated the trust and we lower 586 00:24:49,590 --> 00:24:48,250 the batteries down and put them in place 587 00:24:51,570 --> 00:24:49,600 and then torque them down but in the 588 00:24:53,940 --> 00:24:51,580 case these in MBS use and some other 589 00:24:55,320 --> 00:24:53,950 components we weren't able to do that so 590 00:24:56,910 --> 00:24:55,330 part of what will look as the futures 591 00:24:58,590 --> 00:24:56,920 which ones do we expect to have trouble 592 00:25:01,530 --> 00:24:58,600 which ones might have slightly gold 593 00:25:04,350 --> 00:25:01,540 bolts so that will will know to you know 594 00:25:06,330 --> 00:25:04,360 just expect to the plan the EBA around a 595 00:25:08,160 --> 00:25:06,340 you know chasing the threads or whatever 596 00:25:10,560 --> 00:25:08,170 else we think is the the technique we 597 00:25:13,230 --> 00:25:10,570 need to use but but this isn't this 598 00:25:15,720 --> 00:25:13,240 isn't an age issue this is this just has 599 00:25:17,430 --> 00:25:15,730 to do with the the way we had to install 600 00:25:19,590 --> 00:25:17,440 on the ground and and what it ultimately 601 00:25:23,490 --> 00:25:19,600 does to the interface when you install 602 00:25:25,920 --> 00:25:23,500 it that way ok that's all the questions 603 00:25:28,620 --> 00:25:25,930 for now here in houston will go to the 604 00:25:32,910 --> 00:25:28,630 telephone lines i think in order of 605 00:25:36,810 --> 00:25:32,920 Colin Jim Oberg with NBC yeah I might 606 00:25:38,550 --> 00:25:36,820 turn off the TV or below the way I would 607 00:25:45,330 --> 00:25:38,560 ask you to go back look the big picture 608 00:25:47,610 --> 00:25:45,340 of the of the big 14 failures and this 609 00:25:51,090 --> 00:25:47,620 was one of the big 14 that it fixed but 610 00:25:53,210 --> 00:25:51,100 isn't there another big 14 already out 611 00:25:56,790 --> 00:25:53,220 there in the weeds waiting for you and 612 00:25:59,730 --> 00:25:56,800 are these so far the work of your big 14 613 00:26:01,080 --> 00:25:59,740 list the past two years the second third 614 00:26:04,530 --> 00:26:01,090 failures were there some more that we 615 00:26:06,420 --> 00:26:04,540 didn't notice let's see big 12 so that's 616 00:26:10,560 --> 00:26:06,430 an interesting question because it's 617 00:26:15,570 --> 00:26:10,570 it's 12 now by the way and we think we 618 00:26:18,870 --> 00:26:15,580 think we've settled on that number so so 619 00:26:21,570 --> 00:26:18,880 as you rightly recall the NBS you and 620 00:26:24,350 --> 00:26:21,580 the pump module both on the big 12 list 621 00:26:26,880 --> 00:26:24,360 and and we've learned even more about 622 00:26:29,130 --> 00:26:26,890 installing these kinds of boxes we have 623 00:26:32,700 --> 00:26:29,140 particular mDM's that are on the big 12 624 00:26:33,510 --> 00:26:32,710 list we have the fluid hose rotary 625 00:26:38,970 --> 00:26:33,520 coupler with 626 00:26:41,400 --> 00:26:38,980 is them the coupler that the radiators 627 00:26:43,080 --> 00:26:41,410 rotate around it allows the fluid hoses 628 00:26:44,760 --> 00:26:43,090 to rotate around the radiator and get 629 00:26:47,760 --> 00:26:44,770 the fluid to the radiator so that's one 630 00:26:49,440 --> 00:26:47,770 so we so we have this list of 12 we're 631 00:26:51,270 --> 00:26:49,450 working through them now part of what 632 00:26:52,800 --> 00:26:51,280 we're doing is reviewing the procedures 633 00:26:56,460 --> 00:26:52,810 making sure the procedures are well 634 00:26:57,720 --> 00:26:56,470 potted before we we had procedures and 635 00:27:00,030 --> 00:26:57,730 we thought we understood how they went 636 00:27:02,220 --> 00:27:00,040 but we hadn't done a lot of pool runs we 637 00:27:04,320 --> 00:27:02,230 hadn't spent a lot of time trying to 638 00:27:06,780 --> 00:27:04,330 figure out the technique so we we just 639 00:27:08,220 --> 00:27:06,790 made sure we were able to do the steps 640 00:27:11,520 --> 00:27:08,230 we thought were necessary to change out 641 00:27:13,410 --> 00:27:11,530 that component so part of the the work 642 00:27:17,010 --> 00:27:13,420 being done on all the big 12's and we've 643 00:27:18,720 --> 00:27:17,020 got a little ways to go is to run these 644 00:27:21,450 --> 00:27:18,730 in the pool make sure we understand the 645 00:27:23,670 --> 00:27:21,460 techniques and the other to me more 646 00:27:24,930 --> 00:27:23,680 critical is to understand how you're 647 00:27:26,640 --> 00:27:24,940 going to work around that interface 648 00:27:28,470 --> 00:27:26,650 until you make that change so that you 649 00:27:30,330 --> 00:27:28,480 stay in his robusta position remember on 650 00:27:31,980 --> 00:27:30,340 the on the pump module one of the 651 00:27:34,200 --> 00:27:31,990 challenges we had was we couldn't cool 652 00:27:35,880 --> 00:27:34,210 the arm we're supposed to have redundant 653 00:27:37,500 --> 00:27:35,890 power in the arm and we had to do a lot 654 00:27:39,570 --> 00:27:37,510 of work to figure out well actually we 655 00:27:42,330 --> 00:27:39,580 could provide redundant power to the 656 00:27:43,920 --> 00:27:42,340 armed with an uncooled EDC you and we 657 00:27:45,720 --> 00:27:43,930 had certain jumpers we use to put 658 00:27:47,610 --> 00:27:45,730 ourselves a more favorable coming fig so 659 00:27:48,810 --> 00:27:47,620 that's probably one of the biggest 660 00:27:50,460 --> 00:27:48,820 things we're having to work through in 661 00:27:53,970 --> 00:27:50,470 each of these is how do you get yourself 662 00:27:55,740 --> 00:27:53,980 in a more robust posture just to survive 663 00:27:58,320 --> 00:27:55,750 but also to make sure you can go outside 664 00:28:00,570 --> 00:27:58,330 which takes certain power to it to the 665 00:28:02,220 --> 00:28:00,580 airlock and certain systems so you can 666 00:28:04,710 --> 00:28:02,230 get yourself posture go outside use the 667 00:28:07,380 --> 00:28:04,720 systems you normally use to do that do 668 00:28:11,010 --> 00:28:07,390 the change out so whether we've done 669 00:28:12,480 --> 00:28:11,020 more than two of the big 12 I don't 670 00:28:16,320 --> 00:28:12,490 remember off the top of my head I don't 671 00:28:19,140 --> 00:28:16,330 think so but as you can tell here we're 672 00:28:21,300 --> 00:28:19,150 MBS you was on there we've done quite a 673 00:28:24,150 --> 00:28:21,310 bit of work in the SU but we've also 674 00:28:25,890 --> 00:28:24,160 learned along the way I think the CVA 675 00:28:27,500 --> 00:28:25,900 told us more I don't know if that gets 676 00:28:30,840 --> 00:28:27,510 what you were pulling on Jim but 677 00:28:33,060 --> 00:28:30,850 hopefully a betrayal that you've been a 678 00:28:37,400 --> 00:28:33,070 lisp I had but maybe it's been taken off 679 00:28:40,140 --> 00:28:37,410 which one the DC study at the dcs you 680 00:28:41,550 --> 00:28:40,150 know member of the dcs use on their SS 681 00:28:43,170 --> 00:28:41,560 you and dcs you are never took it off 682 00:28:44,730 --> 00:28:43,180 took it off yeah there you go where 683 00:28:45,340 --> 00:28:44,740 we're living through a dcs you down 684 00:28:47,850 --> 00:28:45,350 actually 685 00:28:52,360 --> 00:28:47,860 now yeah it's not completely down but 686 00:28:54,070 --> 00:28:52,370 but an RBI is down but I syst don't 687 00:28:56,500 --> 00:28:54,080 remember the conversation but I suspect 688 00:28:57,880 --> 00:28:56,510 it has to do with prior to that you know 689 00:28:59,950 --> 00:28:57,890 we weren't his robust we had very few 690 00:29:02,110 --> 00:28:59,960 power channels in the early days now 691 00:29:03,340 --> 00:29:02,120 we've got all eight channels so right 692 00:29:04,750 --> 00:29:03,350 now like we're saying we're breathing a 693 00:29:07,390 --> 00:29:04,760 sigh of relief we've got seven to eight 694 00:29:10,299 --> 00:29:07,400 channels and so one channel down it's 695 00:29:12,340 --> 00:29:10,309 not a it's not it's not a position want 696 00:29:14,289 --> 00:29:12,350 to be in but it's you know it doesn't 697 00:29:15,700 --> 00:29:14,299 send you into really worrying and having 698 00:29:18,190 --> 00:29:15,710 to rush out the door I could just check 699 00:29:20,980 --> 00:29:18,200 it out but I'll gain hats off to the ifm 700 00:29:23,380 --> 00:29:20,990 group miracle workers in the great 701 00:29:28,180 --> 00:29:23,390 tradition yeah you know EDD said it 702 00:29:30,039 --> 00:29:28,190 really well and and I've you know I it's 703 00:29:31,960 --> 00:29:30,049 a treat for me to be the program manager 704 00:29:34,750 --> 00:29:31,970 in this program the number of people 705 00:29:38,289 --> 00:29:34,760 that were involved in coming up with 706 00:29:41,830 --> 00:29:38,299 ideas and and the folks that actually 707 00:29:44,320 --> 00:29:41,840 took those ideas and put them in a shape 708 00:29:48,760 --> 00:29:44,330 tools around that what crews could do on 709 00:29:51,100 --> 00:29:48,770 orbit using the stuff we had on orbit it 710 00:29:53,560 --> 00:29:51,110 was an amazing amazing thing to watch 711 00:29:55,960 --> 00:29:53,570 and behold and and it deserves a lot of 712 00:29:57,970 --> 00:29:55,970 credit is he he brought a big team of 713 00:30:00,100 --> 00:29:57,980 folks together not just the ops guys but 714 00:30:01,720 --> 00:30:00,110 the engineering guys in the MER as he 715 00:30:04,419 --> 00:30:01,730 said you know the texts were we called 716 00:30:06,070 --> 00:30:04,429 text one of them was in retirement that 717 00:30:07,600 --> 00:30:06,080 it's been a lot of time talking to us 718 00:30:10,210 --> 00:30:07,610 and explained to us to challenge the 719 00:30:12,039 --> 00:30:10,220 whole Boeing team was involved it was it 720 00:30:15,610 --> 00:30:12,049 was a great effort these guys have the 721 00:30:17,950 --> 00:30:15,620 experience and and the dedication and 722 00:30:19,990 --> 00:30:17,960 the attention to detail that you have to 723 00:30:23,049 --> 00:30:20,000 have to be successful in this 724 00:30:24,669 --> 00:30:23,059 environment and and sometimes they make 725 00:30:28,470 --> 00:30:24,679 it look a lot easier than it really is 726 00:30:31,630 --> 00:30:28,480 yeah and the girls another portal around 727 00:30:34,840 --> 00:30:31,640 thanks Jim on to mark karo with aviation 728 00:30:38,049 --> 00:30:34,850 week you know thank you Mark Corral from 729 00:30:41,590 --> 00:30:38,059 aviation week could you provide kind of 730 00:30:43,960 --> 00:30:41,600 status on the DD s you power trip on 731 00:30:46,480 --> 00:30:43,970 saturday is that something that book 732 00:30:49,390 --> 00:30:46,490 requires spacewalk ultimately to repair 733 00:30:50,980 --> 00:30:49,400 or is it still being evaluated well 734 00:30:54,460 --> 00:30:50,990 first of all we got to figure out 735 00:30:56,799 --> 00:30:54,470 exactly what trip so and it might have 736 00:30:58,870 --> 00:30:56,809 more so it jumps to learn when you're 737 00:31:01,420 --> 00:30:58,880 ready but the 738 00:31:03,400 --> 00:31:01,430 what what happened what did trip was an 739 00:31:05,650 --> 00:31:03,410 RBI in the dcs you but it was a reaction 740 00:31:07,840 --> 00:31:05,660 to something outside the dcs you that 741 00:31:10,570 --> 00:31:07,850 occurred either in the sequential shunt 742 00:31:12,700 --> 00:31:10,580 unit which is the solar rate beast power 743 00:31:14,980 --> 00:31:12,710 through the sequential shunt unit or 744 00:31:17,350 --> 00:31:14,990 it's an actually the the beta gimbal 745 00:31:19,690 --> 00:31:17,360 itself we refer to it as a broom but 746 00:31:21,790 --> 00:31:19,700 it's the rotating device that the power 747 00:31:23,380 --> 00:31:21,800 then goes through on its way to the dcs 748 00:31:26,290 --> 00:31:23,390 you and then at the dcs you it's 749 00:31:27,850 --> 00:31:26,300 distributed to the different locations 750 00:31:30,880 --> 00:31:27,860 to provide power where it's supposed to 751 00:31:33,940 --> 00:31:30,890 and so the dcs you reacted to what 752 00:31:36,430 --> 00:31:33,950 appears to be a short was a very high 753 00:31:38,740 --> 00:31:36,440 negative current short-lived negative 754 00:31:40,690 --> 00:31:38,750 current draw that tripped it now we have 755 00:31:43,600 --> 00:31:40,700 inside and we can see that that short is 756 00:31:45,700 --> 00:31:43,610 not there anymore so the the even though 757 00:31:48,310 --> 00:31:45,710 we're not providing power what we have 758 00:31:52,630 --> 00:31:48,320 to figure out is it was it the SSU or 759 00:31:54,520 --> 00:31:52,640 the or the role ring or is there some 760 00:31:55,950 --> 00:31:54,530 wiring issue in between which is hard to 761 00:31:58,480 --> 00:31:55,960 believe something like that would be 762 00:31:59,980 --> 00:31:58,490 momentary so we have a lot of work in 763 00:32:02,140 --> 00:31:59,990 front of us to try to sort through that 764 00:32:03,970 --> 00:32:02,150 when we kind of set it aside we're 765 00:32:06,190 --> 00:32:03,980 keeping power to the batteries we've got 766 00:32:09,070 --> 00:32:06,200 them charged I assume they're charged it 767 00:32:10,570 --> 00:32:09,080 up now now that we have the insight and 768 00:32:12,370 --> 00:32:10,580 we're keeping the we kept in all the 769 00:32:14,380 --> 00:32:12,380 systems on the iea and in good shape 770 00:32:16,630 --> 00:32:14,390 while we we wanted to get through this 771 00:32:19,750 --> 00:32:16,640 CVA and then think about what we need to 772 00:32:21,010 --> 00:32:19,760 do there so I have to go outside or not 773 00:32:22,540 --> 00:32:21,020 don't know we'll have finished going 774 00:32:25,870 --> 00:32:22,550 through the fault three tree and see 775 00:32:27,640 --> 00:32:25,880 what we think the cause was whether or 776 00:32:29,800 --> 00:32:27,650 not this temporary occurrence is 777 00:32:32,110 --> 00:32:29,810 something that is now we can assume 778 00:32:34,870 --> 00:32:32,120 won't happen again or if it's something 779 00:32:36,520 --> 00:32:34,880 we think is about to happen again what 780 00:32:38,140 --> 00:32:36,530 posture we need to be in for the future 781 00:32:40,630 --> 00:32:38,150 so we've got a little bit of work left 782 00:32:42,220 --> 00:32:40,640 to go on that one that didn't I give you 783 00:32:43,840 --> 00:32:42,230 a little history on the operations that 784 00:32:47,350 --> 00:32:43,850 we went through from the time of the 785 00:32:49,210 --> 00:32:47,360 trip until right right now the first 786 00:32:50,860 --> 00:32:49,220 thing of course the first thing we do 787 00:32:52,510 --> 00:32:50,870 when we see something of that nature is 788 00:32:54,070 --> 00:32:52,520 it puts a big red warning up on our 789 00:32:55,450 --> 00:32:54,080 caution and warning summary and we have 790 00:32:56,830 --> 00:32:55,460 procedures in place for any of those 791 00:32:59,890 --> 00:32:56,840 warnings so we took appropriate action 792 00:33:02,770 --> 00:32:59,900 to first just make sure that the vehicle 793 00:33:06,130 --> 00:33:02,780 was safe the channel was safe and moved 794 00:33:08,530 --> 00:33:06,140 on from there the first thing we wanted 795 00:33:10,660 --> 00:33:08,540 to do was isolate the upstream 796 00:33:12,490 --> 00:33:10,670 components which as mr. siffredi 797 00:33:15,220 --> 00:33:12,500 mentioned is the SSU 798 00:33:17,950 --> 00:33:15,230 the broom from the downstream components 799 00:33:19,570 --> 00:33:17,960 and that is the batteries themselves the 800 00:33:22,960 --> 00:33:19,580 thermal loop that the batteries are 801 00:33:24,820 --> 00:33:22,970 cooled under and then the NBS you and in 802 00:33:27,430 --> 00:33:24,830 this case that was NBS you number three 803 00:33:30,100 --> 00:33:27,440 and in this particular situation we're 804 00:33:33,340 --> 00:33:30,110 talking about dcs u3a is what you're 805 00:33:35,230 --> 00:33:33,350 referring to and the dcs you is the box 806 00:33:38,290 --> 00:33:35,240 out right under the solar array that 807 00:33:40,630 --> 00:33:38,300 routes all the power to down to the 808 00:33:43,090 --> 00:33:40,640 different loads we I wanted to isolate 809 00:33:45,070 --> 00:33:43,100 that box from from the solar array 810 00:33:47,350 --> 00:33:45,080 itself and the battery reason and the 811 00:33:49,440 --> 00:33:47,360 load so once we took care of that we 812 00:33:52,090 --> 00:33:49,450 could make use of a function that is 813 00:33:54,100 --> 00:33:52,100 exists in all of the NBS use and that is 814 00:33:56,350 --> 00:33:54,110 we can actually tie two channels 815 00:33:58,480 --> 00:33:56,360 together so we tied the three breach of 816 00:34:01,150 --> 00:33:58,490 the three be channel to the three a 817 00:34:03,820 --> 00:34:01,160 channel and that way the the fully 818 00:34:06,070 --> 00:34:03,830 functional 3b solar array could provide 819 00:34:07,960 --> 00:34:06,080 power to not only its loads but then 820 00:34:10,119 --> 00:34:07,970 also the loads that are all normally 821 00:34:11,800 --> 00:34:10,129 carried by that three a solar array and 822 00:34:14,619 --> 00:34:11,810 that included not only powering the 823 00:34:16,330 --> 00:34:14,629 loads underneath that MBS you so all of 824 00:34:18,940 --> 00:34:16,340 the end loads but it also let us send 825 00:34:20,710 --> 00:34:18,950 power back up into the the trust and we 826 00:34:23,619 --> 00:34:20,720 could actually like you said charge the 827 00:34:26,409 --> 00:34:23,629 batteries under the the three a solar 828 00:34:28,899 --> 00:34:26,419 array and so everything underneath that 829 00:34:31,899 --> 00:34:28,909 dcs you is currently being provided 830 00:34:33,970 --> 00:34:31,909 power from its next door neighbor its 831 00:34:36,490 --> 00:34:33,980 sibling power Channel the three beep our 832 00:34:39,580 --> 00:34:36,500 Channel and the the solar array itself 833 00:34:42,040 --> 00:34:39,590 is still being controlled it's computers 834 00:34:44,590 --> 00:34:42,050 called the Electra electronics control 835 00:34:46,270 --> 00:34:44,600 unit the ECU and that is still 836 00:34:48,639 --> 00:34:46,280 functional the array is still tracking 837 00:34:51,220 --> 00:34:48,649 but is it currently in a mode that we 838 00:34:53,050 --> 00:34:51,230 call being shunted in that none of its 839 00:34:55,330 --> 00:34:53,060 solar power is actually being routed 840 00:34:58,450 --> 00:34:55,340 anywhere so it's not actually collecting 841 00:35:01,140 --> 00:34:58,460 and converting power for our use but it 842 00:35:03,580 --> 00:35:01,150 is tracking just like we wanted to and 843 00:35:04,870 --> 00:35:03,590 so it's in a safe configuration and 844 00:35:07,210 --> 00:35:04,880 that's what we're really going for to 845 00:35:10,600 --> 00:35:07,220 get ready for the EV a today we wanted 846 00:35:12,820 --> 00:35:10,610 to get three a safe be able to power all 847 00:35:14,050 --> 00:35:12,830 of its loads and then we wanted to 848 00:35:16,300 --> 00:35:14,060 understand how to operate the vehicle 849 00:35:18,460 --> 00:35:16,310 with three power channels offline the 850 00:35:21,010 --> 00:35:18,470 two service by MBS you one and then the 851 00:35:23,230 --> 00:35:21,020 three a channel we got that all of that 852 00:35:24,640 --> 00:35:23,240 worked we looked for any problems that 853 00:35:25,630 --> 00:35:24,650 we might have with that going into this 854 00:35:28,420 --> 00:35:25,640 EBA 855 00:35:30,849 --> 00:35:28,430 it only required some minor changes to 856 00:35:33,240 --> 00:35:30,859 our plans for doing power downs but then 857 00:35:36,430 --> 00:35:33,250 we were able to press into today zva and 858 00:35:38,109 --> 00:35:36,440 the goal was as soon as this EBA was 859 00:35:39,940 --> 00:35:38,119 done start doing all the work that mr. 860 00:35:41,769 --> 00:35:39,950 suffered Ian talked about in assessing 861 00:35:43,269 --> 00:35:41,779 how we can get the three a channel back 862 00:35:45,069 --> 00:35:43,279 of what needs to be done there it 863 00:35:46,779 --> 00:35:45,079 wouldn't be surprising to me if the team 864 00:35:48,549 --> 00:35:46,789 isn't already meeting to start looking 865 00:35:50,920 --> 00:35:48,559 at that problem now that we've got NBS 866 00:35:52,750 --> 00:35:50,930 you one up and running that's just the 867 00:35:54,430 --> 00:35:52,760 the engineers involved in the team 868 00:35:56,319 --> 00:35:54,440 involved is that once the problems 869 00:35:58,420 --> 00:35:56,329 behind us we just move on to the next 870 00:36:04,630 --> 00:35:58,430 thing that we have to take care of and 871 00:36:07,150 --> 00:36:04,640 we keep the laboratory running okay Hank 872 00:36:10,799 --> 00:36:07,160 further from you mark up good thank you 873 00:36:14,500 --> 00:36:10,809 very much ok onda Marcia done with AP 874 00:36:17,980 --> 00:36:14,510 yes hi I was wondering oh when do you 875 00:36:19,870 --> 00:36:17,990 expect to be back up to where you are or 876 00:36:23,650 --> 00:36:19,880 so to speak not counting this latest 877 00:36:25,539 --> 00:36:23,660 problem just you know do you expect have 878 00:36:28,269 --> 00:36:25,549 all the systems back to be on the proper 879 00:36:32,259 --> 00:36:28,279 circuits in a day or are they already on 880 00:36:34,660 --> 00:36:32,269 that way now well I can tuck the near 881 00:36:38,769 --> 00:36:34,670 term plan as far as reconfiguring the 882 00:36:41,109 --> 00:36:38,779 systems the immediate response we've 883 00:36:43,299 --> 00:36:41,119 already got the NBS you up and running 884 00:36:45,549 --> 00:36:43,309 and powering providing power to the DC 885 00:36:48,009 --> 00:36:45,559 DC converter units underneath it and 886 00:36:51,279 --> 00:36:48,019 like we talked about last week some of 887 00:36:53,559 --> 00:36:51,289 those converters are the only provider 888 00:36:56,230 --> 00:36:53,569 of power to some of our avionics and in 889 00:36:58,779 --> 00:36:56,240 other cases those converters share loads 890 00:37:00,279 --> 00:36:58,789 with what we call parallel ddc use being 891 00:37:02,769 --> 00:37:00,289 power from other channels so when you 892 00:37:05,559 --> 00:37:02,779 have the two ddc use together sharing 893 00:37:09,130 --> 00:37:05,569 the loads we have repowered those ddc 894 00:37:11,859 --> 00:37:09,140 use and now that 1a and 1b power is 895 00:37:13,630 --> 00:37:11,869 jointly feeding all of the loads and 896 00:37:17,319 --> 00:37:13,640 that is a nominal configuration that's 897 00:37:21,490 --> 00:37:17,329 that's normal two of our primary load 898 00:37:23,980 --> 00:37:21,500 carriers are ddc you one Bravo and then 899 00:37:26,740 --> 00:37:23,990 also at zero one alpha and what that is 900 00:37:29,319 --> 00:37:26,750 one side powers half of the avionics in 901 00:37:30,819 --> 00:37:29,329 the US lab the other side powers things 902 00:37:32,650 --> 00:37:30,829 like one of our external thermal loop 903 00:37:35,289 --> 00:37:32,660 pumps and one of our s band strings 904 00:37:37,120 --> 00:37:35,299 right now all of those loads are being 905 00:37:38,349 --> 00:37:37,130 powered through jumpers and we talked 906 00:37:38,930 --> 00:37:38,359 about those last week and how we've 907 00:37:41,630 --> 00:37:38,940 rerouted 908 00:37:43,730 --> 00:37:41,640 power through those jumpers now over the 909 00:37:45,530 --> 00:37:43,740 next two days we'll be removing those 910 00:37:47,630 --> 00:37:45,540 jumpers and that will get us back into 911 00:37:49,880 --> 00:37:47,640 the standard configuration so tomorrow 912 00:37:51,440 --> 00:37:49,890 we're going to remove the internal the 913 00:37:54,770 --> 00:37:51,450 the jumper that's providing power to the 914 00:37:57,380 --> 00:37:54,780 internal loads and then on Friday 915 00:37:59,000 --> 00:37:57,390 today's Wednesday and Friday will be 916 00:38:00,800 --> 00:37:59,010 removing the jumper that provides power 917 00:38:04,220 --> 00:38:00,810 to the external loads and then we'll be 918 00:38:08,089 --> 00:38:04,230 back in the normal configuration for the 919 00:38:10,309 --> 00:38:08,099 MBS you one service loads thank you and 920 00:38:13,490 --> 00:38:10,319 one other question I think I may know 921 00:38:15,859 --> 00:38:13,500 the answer but did you say that this was 922 00:38:17,900 --> 00:38:15,869 a defect that was introduced on the 923 00:38:19,190 --> 00:38:17,910 ground prior to launch the fact that all 924 00:38:22,190 --> 00:38:19,200 these metal shavings were in their 925 00:38:24,050 --> 00:38:22,200 jamming the the socket I just went 926 00:38:26,450 --> 00:38:24,060 trying to get a handle on how this 927 00:38:29,000 --> 00:38:26,460 actually happened to begin with well 928 00:38:31,970 --> 00:38:29,010 it's a and I don't know how to call it a 929 00:38:34,640 --> 00:38:31,980 defect as a result of how we had to 930 00:38:36,890 --> 00:38:34,650 install it we think we probably called 931 00:38:39,200 --> 00:38:36,900 the bolt as we were installing it and so 932 00:38:41,569 --> 00:38:39,210 the result of that is you damage the 933 00:38:45,829 --> 00:38:41,579 threads a little bit and leave you leave 934 00:38:48,800 --> 00:38:45,839 shavings behind and that's likely the 935 00:38:52,730 --> 00:38:48,810 source of the shavings that we found in 936 00:38:56,690 --> 00:38:52,740 the and the trouble we had with with the 937 00:38:58,490 --> 00:38:56,700 post threads that speculation but it's 938 00:39:01,250 --> 00:38:58,500 AB it's pretty good guess it'd be hard 939 00:39:04,609 --> 00:39:01,260 to do that kind of we just remove the 940 00:39:08,380 --> 00:39:04,619 bolt on orbit so it'd be hard to leave 941 00:39:12,290 --> 00:39:08,390 that kind of that number of threads I 942 00:39:13,700 --> 00:39:12,300 mean that amount of shavings that we saw 943 00:39:18,200 --> 00:39:13,710 with a little bit of work we did on 944 00:39:22,010 --> 00:39:18,210 orbit so that's the speculation thank 945 00:39:28,570 --> 00:39:22,020 you okay next is todd halvorson from 946 00:39:35,050 --> 00:39:31,000 well not hearing from Todd Denise with 947 00:39:39,240 --> 00:39:35,060 space com hi thank you I think it was 948 00:39:42,190 --> 00:39:39,250 Jack Fisher and Mission Control once the 949 00:39:43,990 --> 00:39:42,200 unit has been installed and powered up 950 00:39:46,180 --> 00:39:44,000 he said that when he was congratulating 951 00:39:49,690 --> 00:39:46,190 curly came that it felt a little bit 952 00:39:51,280 --> 00:39:49,700 like being on the set of Apollo 13 I was 953 00:39:53,920 --> 00:39:51,290 wondering eid or Keith if you could 954 00:39:56,080 --> 00:39:53,930 describe what kind of tension we were 955 00:39:59,220 --> 00:39:56,090 feeling in Mission Control today and 956 00:40:04,090 --> 00:39:59,230 also in the days leading up to the ETA 957 00:40:06,040 --> 00:40:04,100 i'll start you know there's one thing 958 00:40:07,720 --> 00:40:06,050 with apollo 13 and the issues that they 959 00:40:11,050 --> 00:40:07,730 faced obviously that was life 960 00:40:12,550 --> 00:40:11,060 threatening to the crew and the efforts 961 00:40:14,950 --> 00:40:12,560 that they were working through then was 962 00:40:18,490 --> 00:40:14,960 how to get the crew home safely alive we 963 00:40:20,740 --> 00:40:18,500 obviously weren't in that situation but 964 00:40:22,510 --> 00:40:20,750 what the similarities really were there 965 00:40:26,860 --> 00:40:22,520 though to watch how the team came 966 00:40:28,510 --> 00:40:26,870 together just the the the scene that 967 00:40:32,130 --> 00:40:28,520 comes to mind for the movie and we did 968 00:40:34,510 --> 00:40:32,140 make jokes and talk about Apollo 13 and 969 00:40:35,770 --> 00:40:34,520 failure is not an option as certainly is 970 00:40:37,180 --> 00:40:35,780 something that I mentioned a couple of 971 00:40:40,750 --> 00:40:37,190 times because we had to get this thing 972 00:40:43,480 --> 00:40:40,760 installed but the scene where where the 973 00:40:45,580 --> 00:40:43,490 engineers came in and dumped a box full 974 00:40:46,960 --> 00:40:45,590 of here's the stuff they've got on the 975 00:40:49,720 --> 00:40:46,970 vehicle let's figure out how to make 976 00:40:51,760 --> 00:40:49,730 this work for their co2 scrubber we 977 00:40:53,920 --> 00:40:51,770 didn't use any socks but we pretty much 978 00:40:55,660 --> 00:40:53,930 pulled a bunch of different pieces out 979 00:40:59,740 --> 00:40:55,670 of our pantries and put together an 980 00:41:03,940 --> 00:40:59,750 amazing set of tools and the free flow 981 00:41:05,560 --> 00:41:03,950 of ideas from any corner that that might 982 00:41:07,480 --> 00:41:05,570 have helped us it was just like it was 983 00:41:11,590 --> 00:41:07,490 in the in the movie and then also in 984 00:41:13,980 --> 00:41:11,600 real life the the dedication and 985 00:41:16,210 --> 00:41:13,990 professionalism of everyone involved and 986 00:41:17,800 --> 00:41:16,220 something else that I don't know if it's 987 00:41:20,740 --> 00:41:17,810 easy to pick up in the movie but if you 988 00:41:22,270 --> 00:41:20,750 watch the movie or if you know about the 989 00:41:26,290 --> 00:41:22,280 real life story the age of the flight 990 00:41:29,320 --> 00:41:26,300 controllers these are all young kids 991 00:41:33,000 --> 00:41:29,330 that are doing this amazing work and the 992 00:41:35,260 --> 00:41:33,010 same was true in our story the the the 993 00:41:37,470 --> 00:41:35,270 younger generation of flight controllers 994 00:41:39,700 --> 00:41:37,480 that are pulling these things together 995 00:41:40,650 --> 00:41:39,710 assisted by the seasoned veterans that 996 00:41:42,720 --> 00:41:40,660 have been through 997 00:41:44,750 --> 00:41:42,730 things that included first element 998 00:41:47,250 --> 00:41:44,760 launch watching them pull together the 999 00:41:48,539 --> 00:41:47,260 amazing things that we did were that 1000 00:41:51,809 --> 00:41:48,549 they pulled together that allowed us to 1001 00:41:53,579 --> 00:41:51,819 do what we did today really did come 1002 00:41:56,309 --> 00:41:53,589 similar to what it must have been like 1003 00:41:57,420 --> 00:41:56,319 to experience Apollo 13 although we 1004 00:41:59,190 --> 00:41:57,430 didn't weren't allowed to smoke cigars 1005 00:42:06,990 --> 00:41:59,200 in the end so I think they still had it 1006 00:42:08,730 --> 00:42:07,000 a little better no that's it thank you 1007 00:42:11,940 --> 00:42:08,740 all right we'll move on to fill with 1008 00:42:14,250 --> 00:42:11,950 NASA Space Flight com has already 1009 00:42:17,220 --> 00:42:14,260 covered everything for me thanks all 1010 00:42:19,890 --> 00:42:17,230 right bill Harwood CBS yeah just one 1011 00:42:22,200 --> 00:42:19,900 more a dcs you question for it I guess 1012 00:42:24,809 --> 00:42:22,210 are there any operational constraints to 1013 00:42:26,730 --> 00:42:24,819 being one channel down or want to write 1014 00:42:28,559 --> 00:42:26,740 down I guess you have to manage anything 1015 00:42:30,599 --> 00:42:28,569 because you don't have all eight running 1016 00:42:34,020 --> 00:42:30,609 or is it too transparent at this point 1017 00:42:35,760 --> 00:42:34,030 Thanks well you know us so we have 1018 00:42:37,109 --> 00:42:35,770 flight rules for everything some so 1019 00:42:39,359 --> 00:42:37,119 there are there are definitely 1020 00:42:41,660 --> 00:42:39,369 constraints for operating in the 1021 00:42:43,890 --> 00:42:41,670 configuration that we're in right now 1022 00:42:45,900 --> 00:42:43,900 the constraints are a lot lighter now 1023 00:42:47,420 --> 00:42:45,910 that we have MBS you want up and running 1024 00:42:51,450 --> 00:42:47,430 and once we get back into that fully 1025 00:42:53,910 --> 00:42:51,460 normal configuration we will be in good 1026 00:42:56,250 --> 00:42:53,920 shape we talked a lot last week about 1027 00:42:57,029 --> 00:42:56,260 power balance and power loading and 1028 00:42:59,190 --> 00:42:57,039 we're still going to be in that 1029 00:43:01,460 --> 00:42:59,200 situation where we have to manage the 1030 00:43:03,930 --> 00:43:01,470 amount of power that we put on the 1031 00:43:06,750 --> 00:43:03,940 channels and make sure we don't do 1032 00:43:09,799 --> 00:43:06,760 something that might trip off either the 1033 00:43:11,940 --> 00:43:09,809 three a channel or the entire 3a and 3b 1034 00:43:15,000 --> 00:43:11,950 channel because now we have those two 1035 00:43:17,940 --> 00:43:15,010 things tied together we have the power 1036 00:43:21,180 --> 00:43:17,950 recess officers is a it's a group of 1037 00:43:24,240 --> 00:43:21,190 folks that analyze all of our power 1038 00:43:26,760 --> 00:43:24,250 loading the the solar angles where we 1039 00:43:29,250 --> 00:43:26,770 are in the orbit and and they tell us 1040 00:43:30,569 --> 00:43:29,260 what our forecast power usage is 1041 00:43:32,039 --> 00:43:30,579 obviously we've been putting them 1042 00:43:34,289 --> 00:43:32,049 through the grinder for the past week 1043 00:43:36,480 --> 00:43:34,299 and they'll continue to make sure that 1044 00:43:39,569 --> 00:43:36,490 we stay on the on the right path as far 1045 00:43:40,859 --> 00:43:39,579 as our power balance and then we do have 1046 00:43:44,309 --> 00:43:40,869 to make sure that we manage the 1047 00:43:47,010 --> 00:43:44,319 batteries for example we mentioned that 1048 00:43:51,210 --> 00:43:47,020 the the three AAA batteries are being 1049 00:43:53,609 --> 00:43:51,220 charged through the the three be solar 1050 00:43:54,270 --> 00:43:53,619 array but because the 3a and the 3b 1051 00:43:56,790 --> 00:43:54,280 channels are 1052 00:43:58,890 --> 00:43:56,800 tied together the the three a batteries 1053 00:44:01,020 --> 00:43:58,900 aren't going to be taxed as much as they 1054 00:44:03,420 --> 00:44:01,030 otherwise would be because the 3a and 3b 1055 00:44:05,100 --> 00:44:03,430 batteries are sharing the loads and so 1056 00:44:08,010 --> 00:44:05,110 there's actually a potential that we 1057 00:44:09,900 --> 00:44:08,020 could can hit the upper charge limits on 1058 00:44:12,420 --> 00:44:09,910 those batteries if we continue to just 1059 00:44:15,750 --> 00:44:12,430 let them charge so we have insight into 1060 00:44:17,340 --> 00:44:15,760 that and we might force those batteries 1061 00:44:19,800 --> 00:44:17,350 to be used just so we keep their 1062 00:44:22,560 --> 00:44:19,810 charging levels down to where they're I 1063 00:44:23,820 --> 00:44:22,570 think 105 percent is where we try to 1064 00:44:24,960 --> 00:44:23,830 stop them somewhere around there so we 1065 00:44:28,470 --> 00:44:24,970 just keep them make sure they keep 1066 00:44:29,700 --> 00:44:28,480 discharging as we need to on a scale of 1067 00:44:32,040 --> 00:44:29,710 what we've been working through the last 1068 00:44:34,980 --> 00:44:32,050 week though this is going to be a bit 1069 00:44:36,150 --> 00:44:34,990 more manageable for us and we should be 1070 00:44:41,010 --> 00:44:36,160 able to take care of this without any 1071 00:44:44,010 --> 00:44:41,020 problems thank you very much okay last 1072 00:44:46,230 --> 00:44:44,020 but not least Irene Klotz thanks so much 1073 00:44:47,700 --> 00:44:46,240 with my questions have been answered I 1074 00:44:50,490 --> 00:44:47,710 just was curious if you guys have a 1075 00:44:56,520 --> 00:44:50,500 target launch date for the SpaceX right 1076 00:44:59,610 --> 00:44:56,530 thing for SpaceX it's a it's interesting 1077 00:45:02,060 --> 00:44:59,620 it's one of these things where we tried 1078 00:45:04,710 --> 00:45:02,070 to manage our readiness for the vehicle 1079 00:45:06,420 --> 00:45:04,720 given the availability of the range so 1080 00:45:10,050 --> 00:45:06,430 they have the range today on the ninth 1081 00:45:12,900 --> 00:45:10,060 and tenth of October and we're prepared 1082 00:45:15,420 --> 00:45:12,910 to support that however they could fly 1083 00:45:17,820 --> 00:45:15,430 sooner and we prefer them to fly a 1084 00:45:21,810 --> 00:45:17,830 little sooner to just keep ourselves d 1085 00:45:24,210 --> 00:45:21,820 conflicted from the from the the Soyuz 1086 00:45:25,770 --> 00:45:24,220 flight that's coming up and they slip if 1087 00:45:27,360 --> 00:45:25,780 they slip from the 10th we've got to go 1088 00:45:29,070 --> 00:45:27,370 to the other side of the so you slide so 1089 00:45:31,260 --> 00:45:29,080 what we'd like to do is try a little 1090 00:45:34,440 --> 00:45:31,270 earlier if we can think there's an atlas 1091 00:45:36,360 --> 00:45:34,450 on the range so we're ready to fly 1092 00:45:38,940 --> 00:45:36,370 they'll be ready to fly some understands 1093 00:45:40,430 --> 00:45:38,950 early as the fifth of October and will 1094 00:45:43,310 --> 00:45:40,440 be prepared to take them on the fifth of 1095 00:45:45,330 --> 00:45:43,320 October but right now the ranges is 1096 00:45:46,830 --> 00:45:45,340 occupied on that date so if something 1097 00:45:48,660 --> 00:45:46,840 changes on the range then we'll try 1098 00:45:51,180 --> 00:45:48,670 earlier other right otherwise right now 1099 00:45:52,710 --> 00:45:51,190 we've got them there on the range for 1100 00:45:53,490 --> 00:45:52,720 the ninth and we're prepared for them to 1101 00:45:59,940 --> 00:45:53,500 arrive 1102 00:46:01,650 --> 00:45:59,950 after that launch okay well not seeing 1103 00:46:03,690 --> 00:46:01,660 any further follow-ups here in Houston 1104 00:46:05,340 --> 00:46:03,700 will close this briefing out thank you 1105 00:46:07,380 --> 00:46:05,350 very much for being here today remember 1106 00:46:09,150 --> 00:46:07,390 that all the latest information on the 1107 00:46:13,350 --> 00:46:09,160 International Space Station is available
