1 00:00:05,860 --> 00:00:04,280 welcome to this launch status news 2 00:00:07,760 --> 00:00:05,870 conference for Space Shuttle Endeavour's 3 00:00:09,500 --> 00:00:07,770 sts-134 mission to the International 4 00:00:10,970 --> 00:00:09,510 Space Station joining us at NASA's 5 00:00:12,320 --> 00:00:10,980 Kennedy Space Center this afternoon our 6 00:00:13,549 --> 00:00:12,330 two managers will give us the latest on 7 00:00:15,589 --> 00:00:13,559 efforts to prepare endeavour for its 8 00:00:17,150 --> 00:00:15,599 next launch attempt first we have space 9 00:00:18,890 --> 00:00:17,160 shuttle launch integration manager and 10 00:00:22,939 --> 00:00:18,900 mission management team chair Mike Moses 11 00:00:25,130 --> 00:00:22,949 Efrain and shuttle launch director Mike 12 00:00:26,330 --> 00:00:25,140 Leinbach good afternoon or start with 13 00:00:28,609 --> 00:00:26,340 some opening comments about where we are 14 00:00:31,460 --> 00:00:28,619 and then open to questions sir thanks 15 00:00:32,630 --> 00:00:31,470 Alan let's see yeah the team's been 16 00:00:34,880 --> 00:00:32,640 working really hard on the 17 00:00:36,709 --> 00:00:34,890 troubleshooting plan we've been getting 18 00:00:39,799 --> 00:00:36,719 getting information updates as they go 19 00:00:41,150 --> 00:00:39,809 it was a pretty good a pretty good plan 20 00:00:43,040 --> 00:00:41,160 that they had and I'll let Mike go into 21 00:00:45,830 --> 00:00:43,050 the details of how they got to where 22 00:00:48,740 --> 00:00:45,840 that we are today but but the the bottom 23 00:00:50,720 --> 00:00:48,750 line is that the failure that we have 24 00:00:53,510 --> 00:00:50,730 appears to be a power problem which is 25 00:00:55,910 --> 00:00:53,520 in the LCA the load control assembly box 26 00:00:59,090 --> 00:00:55,920 which is basically a box of switches 27 00:01:01,700 --> 00:00:59,100 that we use to control power feeds so 28 00:01:03,680 --> 00:01:01,710 that's an electronic box so that 29 00:01:05,509 --> 00:01:03,690 basically means that the the powers not 30 00:01:07,010 --> 00:01:05,519 getting out to the heaters that that 31 00:01:08,780 --> 00:01:07,020 weren't working on launch day and we 32 00:01:11,780 --> 00:01:08,790 need to go in and change out that box 33 00:01:14,570 --> 00:01:11,790 the team had some options in case it was 34 00:01:16,070 --> 00:01:14,580 a ground side problem on the on the 35 00:01:17,960 --> 00:01:16,080 ground electrically grounded side 36 00:01:20,090 --> 00:01:17,970 problem we could have may be kind of hot 37 00:01:22,370 --> 00:01:20,100 wired our way around and and rewired a 38 00:01:23,990 --> 00:01:22,380 few things but this is on the upstream 39 00:01:25,330 --> 00:01:24,000 side so it's the power feed side and 40 00:01:27,620 --> 00:01:25,340 there really are no options other than 41 00:01:29,990 --> 00:01:27,630 replacing the failed component which 42 00:01:31,580 --> 00:01:30,000 requires removing the whole box so that 43 00:01:32,539 --> 00:01:31,590 works gonna take us a while so 44 00:01:33,590 --> 00:01:32,549 unfortunately we're not gonna be able to 45 00:01:35,690 --> 00:01:33,600 make a launch attempt here in the next 46 00:01:36,859 --> 00:01:35,700 few days I'm here to disappoint 47 00:01:37,760 --> 00:01:36,869 everybody by saying I'm not going to 48 00:01:40,490 --> 00:01:37,770 tell you what the new launch date is 49 00:01:43,039 --> 00:01:40,500 because I have no idea we have a lot 50 00:01:45,740 --> 00:01:43,049 more to evaluate both the work to do the 51 00:01:48,380 --> 00:01:45,750 RNR the retest that has to be done how 52 00:01:49,940 --> 00:01:48,390 we work all that schedule in there's 53 00:01:51,200 --> 00:01:49,950 their APIs on the range lunch and on the 54 00:01:53,690 --> 00:01:51,210 sixth right now so we have to evaluate 55 00:01:56,330 --> 00:01:53,700 conflicts with them and then the mission 56 00:01:57,889 --> 00:01:56,340 timelines and the ISS time would be 57 00:02:00,740 --> 00:01:57,899 coming up as we move to the other side 58 00:02:02,810 --> 00:02:00,750 of the Atlas we'd be looking at some 59 00:02:04,670 --> 00:02:02,820 potential conflicts with the 25 Soyuz 60 00:02:06,410 --> 00:02:04,680 undocking and we want to make sure we D 61 00:02:09,020 --> 00:02:06,420 conflict the right way with that 62 00:02:10,190 --> 00:02:09,030 activity so right now we are we're not 63 00:02:12,350 --> 00:02:10,200 ready to settle launch date we're going 64 00:02:13,520 --> 00:02:12,360 to need a couple more days we might have 65 00:02:15,920 --> 00:02:13,530 an M empty tomorrow to pick the 66 00:02:17,059 --> 00:02:15,930 we might go to Tuesday and do that will 67 00:02:19,100 --> 00:02:17,069 kind of wait and see where we have 68 00:02:20,300 --> 00:02:19,110 enough data to make that decision but we 69 00:02:22,610 --> 00:02:20,310 can tell you pretty much that it's not 70 00:02:23,960 --> 00:02:22,620 gonna be any earlier than the 8th that 71 00:02:25,670 --> 00:02:23,970 doesn't mean we're gonna go launch on 72 00:02:27,080 --> 00:02:25,680 the 8th that just means we know right 73 00:02:28,970 --> 00:02:27,090 now the 8th is our next available 74 00:02:30,229 --> 00:02:28,980 opening so we'll kind of start looking 75 00:02:32,240 --> 00:02:30,239 at that but we're really not even 76 00:02:33,440 --> 00:02:32,250 setting the schedules today there's 77 00:02:36,080 --> 00:02:33,450 still a whole lot of short-term work 78 00:02:37,490 --> 00:02:36,090 that has to be done in addition to once 79 00:02:39,680 --> 00:02:37,500 the box comes out we have to go verify 80 00:02:41,600 --> 00:02:39,690 circuitry and prove that the box itself 81 00:02:42,920 --> 00:02:41,610 was the failure and that there's not 82 00:02:45,320 --> 00:02:42,930 some other failure in the ship somewhere 83 00:02:46,610 --> 00:02:45,330 that we're getting fooled by so we still 84 00:02:48,560 --> 00:02:46,620 have a lot of work and a lot of off 85 00:02:50,420 --> 00:02:48,570 roads that could take us one way or 86 00:02:52,400 --> 00:02:50,430 another but we're not gonna try any 87 00:02:54,650 --> 00:02:52,410 earlier than the 8th and and we may or 88 00:02:56,600 --> 00:02:54,660 may not be on the 8th itself so again 89 00:02:57,949 --> 00:02:56,610 don't take that as a launch date just 90 00:03:00,140 --> 00:02:57,959 take that as a target for when we're 91 00:03:02,300 --> 00:03:00,150 ready to start talking again about a 92 00:03:03,710 --> 00:03:02,310 lunch date so with that we we knew 93 00:03:05,270 --> 00:03:03,720 enough that we could send folks home the 94 00:03:07,490 --> 00:03:05,280 crew has departed their families are on 95 00:03:08,930 --> 00:03:07,500 their way home all the support teams 96 00:03:10,610 --> 00:03:08,940 from other centers around the country 97 00:03:13,100 --> 00:03:10,620 have gone home or in the process of 98 00:03:14,930 --> 00:03:13,110 going home like I said will then convene 99 00:03:16,699 --> 00:03:14,940 there's a management team on Monday or 100 00:03:19,280 --> 00:03:16,709 Tuesday where we'll start to discuss 101 00:03:20,780 --> 00:03:19,290 future options and bring in the whole 102 00:03:23,060 --> 00:03:20,790 entire team's impacts with the space 103 00:03:25,130 --> 00:03:23,070 station program and then the range and 104 00:03:26,390 --> 00:03:25,140 the Atlas team I talked to them this 105 00:03:28,009 --> 00:03:26,400 morning they're still in really good 106 00:03:29,990 --> 00:03:28,019 shape and on schedule they don't 107 00:03:32,210 --> 00:03:30,000 anticipate any hiccups and their flow 108 00:03:33,740 --> 00:03:32,220 but again obviously we need to be ready 109 00:03:35,449 --> 00:03:33,750 in case they had some problems too as to 110 00:03:37,520 --> 00:03:35,459 how we mutually work through range 111 00:03:39,440 --> 00:03:37,530 conflicts as we get to the get to the 112 00:03:42,140 --> 00:03:39,450 end of end of that week in May so about 113 00:03:44,630 --> 00:03:42,150 a week from now so that's the that's the 114 00:03:46,039 --> 00:03:44,640 quick and dirty answer for us a lot of 115 00:03:48,229 --> 00:03:46,049 more work to happen the teams have been 116 00:03:50,750 --> 00:03:48,239 doing an amazing job up to this point 117 00:03:52,099 --> 00:03:50,760 and again one of the things we can tend 118 00:03:54,170 --> 00:03:52,109 to not try to make decisions too quickly 119 00:03:56,569 --> 00:03:54,180 is is this team is shown again and again 120 00:03:58,069 --> 00:03:56,579 that given enough time they can come up 121 00:03:59,630 --> 00:03:58,079 with some pretty creative solutions so 122 00:04:01,280 --> 00:03:59,640 right now we have what looks like a 123 00:04:03,890 --> 00:04:01,290 boiler plate scheduled to go pull this 124 00:04:05,750 --> 00:04:03,900 box out in the next day you go retest 125 00:04:07,490 --> 00:04:05,760 put a new box in and then do a whole 126 00:04:09,319 --> 00:04:07,500 bunch of checks get back into launch 127 00:04:10,759 --> 00:04:09,329 count that looks like it's a pretty 128 00:04:13,370 --> 00:04:10,769 aggressive schedule to make the end of 129 00:04:14,630 --> 00:04:13,380 next week but but you know they need 130 00:04:16,099 --> 00:04:14,640 more time to go look and see how they 131 00:04:17,270 --> 00:04:16,109 can parallel that work up and what 132 00:04:19,250 --> 00:04:17,280 really has to be in there so we need to 133 00:04:21,199 --> 00:04:19,260 give them that time before we go set any 134 00:04:22,760 --> 00:04:21,209 dates in front of them so so we're gonna 135 00:04:23,600 --> 00:04:22,770 let them do that with that all that Mike 136 00:04:24,649 --> 00:04:23,610 talk to you little more about the 137 00:04:26,360 --> 00:04:24,659 details of how the team's been working 138 00:04:26,730 --> 00:04:26,370 but again can't be more proud of how 139 00:04:29,760 --> 00:04:26,740 they're 140 00:04:30,870 --> 00:04:29,770 make really good decisions based on the 141 00:04:32,760 --> 00:04:30,880 data we have and try not to make any 142 00:04:34,020 --> 00:04:32,770 decisions before we actually have data 143 00:04:35,520 --> 00:04:34,030 and we've been doing pretty good with 144 00:04:38,370 --> 00:04:35,530 that so far so we're gonna keep on that 145 00:04:40,200 --> 00:04:38,380 track go Mike okay thanks 146 00:04:41,700 --> 00:04:40,210 let's say we've had a series of telecoms 147 00:04:43,320 --> 00:04:41,710 over the last day and a half or so to 148 00:04:45,330 --> 00:04:43,330 try to understand this problem little 149 00:04:47,820 --> 00:04:45,340 bit better and as Mike said it does lead 150 00:04:50,430 --> 00:04:47,830 to a box RNR so we're in the process of 151 00:04:52,290 --> 00:04:50,440 gaining a full full platform set in they 152 00:04:54,270 --> 00:04:52,300 after the orbiter that's not required 153 00:04:55,650 --> 00:04:54,280 for the box itself that's required for 154 00:04:56,700 --> 00:04:55,660 some of the retest we have to get all 155 00:04:59,430 --> 00:04:56,710 the way down to the bottom they have 156 00:05:01,020 --> 00:04:59,440 compartment for some of the retest so 157 00:05:02,760 --> 00:05:01,030 that access is going into the after the 158 00:05:05,129 --> 00:05:02,770 orbiter right now we're also 159 00:05:07,020 --> 00:05:05,139 establishing the connection for the 160 00:05:09,469 --> 00:05:07,030 orbiter mid body umbilical unit that's 161 00:05:11,969 --> 00:05:09,479 the unit that we use to drain the PRS D 162 00:05:13,830 --> 00:05:11,979 cryogenics we need to offload PRS D for 163 00:05:16,200 --> 00:05:13,840 this operation we also need to 164 00:05:17,610 --> 00:05:16,210 disconnect our ordnance complete 165 00:05:18,930 --> 00:05:17,620 ordnance or partial ordnance that's 166 00:05:20,339 --> 00:05:18,940 still an open question for the team 167 00:05:23,010 --> 00:05:20,349 they'll come to grips with that later 168 00:05:24,719 --> 00:05:23,020 this afternoon or this evening and then 169 00:05:26,790 --> 00:05:24,729 we'll power down the ship tomorrow and 170 00:05:28,379 --> 00:05:26,800 that will effectively take us out it 171 00:05:30,749 --> 00:05:28,389 does it take it takes us out of launch 172 00:05:31,110 --> 00:05:30,759 countdown and then we'll get into the 173 00:05:33,240 --> 00:05:31,120 box 174 00:05:35,040 --> 00:05:33,250 removal we'll check the cold plate under 175 00:05:37,110 --> 00:05:35,050 the box right now to make sure there are 176 00:05:39,330 --> 00:05:37,120 no dings as we were pulling the Box off 177 00:05:41,279 --> 00:05:39,340 we'll put in the new box and then we'll 178 00:05:43,409 --> 00:05:41,289 get into the retest the retest is quite 179 00:05:46,290 --> 00:05:43,419 lengthy we've done this once before and 180 00:05:48,779 --> 00:05:46,300 the integrated flow STS 70 I believe it 181 00:05:49,980 --> 00:05:48,789 was and there are nine different systems 182 00:05:51,870 --> 00:05:49,990 we're going to have to retest they're 183 00:05:54,089 --> 00:05:51,880 quite lengthy retest I think we reported 184 00:05:55,379 --> 00:05:54,099 the other day two full days of retest 185 00:05:57,420 --> 00:05:55,389 we're taking a good hard look at that 186 00:05:59,580 --> 00:05:57,430 schedule that was developed many years 187 00:06:01,350 --> 00:05:59,590 ago to see if that's a still all 188 00:06:03,839 --> 00:06:01,360 required or maybe there's even a bit 189 00:06:06,600 --> 00:06:03,849 more but right now our our tentative 190 00:06:08,730 --> 00:06:06,610 plan has two full days of retest after 191 00:06:10,620 --> 00:06:08,740 which we get back in and and connect up 192 00:06:12,719 --> 00:06:10,630 ordnance again get into launch countdown 193 00:06:14,399 --> 00:06:12,729 and it'll be a standard three day launch 194 00:06:14,939 --> 00:06:14,409 countdown we'll start over from ground 195 00:06:17,100 --> 00:06:14,949 zero 196 00:06:19,409 --> 00:06:17,110 and we'll load PRS D two days before 197 00:06:21,390 --> 00:06:19,419 count and then now launch two days later 198 00:06:23,700 --> 00:06:21,400 so it's a it's a heck of a lot of work 199 00:06:24,930 --> 00:06:23,710 ahead of the team I'm extremely proud of 200 00:06:26,670 --> 00:06:24,940 the work we've already done over the 201 00:06:28,830 --> 00:06:26,680 weekend to understand this problem and 202 00:06:30,540 --> 00:06:28,840 now that now that we've essentially 203 00:06:33,120 --> 00:06:30,550 pinpointed the problem to inside the 204 00:06:35,070 --> 00:06:33,130 load control assembly we'll get on about 205 00:06:37,379 --> 00:06:35,080 our business of taking that guy out and 206 00:06:38,910 --> 00:06:37,389 replacing it with the new one so that's 207 00:06:40,470 --> 00:06:38,920 the work in front of us and 208 00:06:41,910 --> 00:06:40,480 Tina's ready to execute the team is 209 00:06:43,320 --> 00:06:41,920 upbeat I'll tell you a little 210 00:06:46,080 --> 00:06:43,330 disappointing of course that we couldn't 211 00:06:47,550 --> 00:06:46,090 launch but you know respond to problems 212 00:06:49,470 --> 00:06:47,560 is one of the things we do best around 213 00:06:51,420 --> 00:06:49,480 here and the team always likes a good 214 00:06:52,950 --> 00:06:51,430 challenge I'm sure we're going to be 215 00:06:55,170 --> 00:06:52,960 really glad when when endeavour is 216 00:06:56,730 --> 00:06:55,180 finally on orbit but right now the team 217 00:06:59,400 --> 00:06:56,740 is upbeat and ready to execute the plan 218 00:07:03,480 --> 00:06:59,410 that we've laid out so with that we'll 219 00:07:05,010 --> 00:07:03,490 be glad to take questions like you said 220 00:07:07,170 --> 00:07:05,020 we'll love when the microphone gets to 221 00:07:08,880 --> 00:07:07,180 you and I think I don't want to go from 222 00:07:11,340 --> 00:07:08,890 here um please wait for the microphone 223 00:07:12,750 --> 00:07:11,350 and name news affiliation to whom you'd 224 00:07:16,920 --> 00:07:12,760 like to answer your question and we'll 225 00:07:18,990 --> 00:07:16,930 start with the front row Marcia Marcia 226 00:07:20,760 --> 00:07:19,000 den Associated Press I'm just wondering 227 00:07:25,230 --> 00:07:20,770 what do you think's wrong with the 228 00:07:28,200 --> 00:07:25,240 switch box and is it any indicate is it 229 00:07:29,940 --> 00:07:28,210 just sort of an illustration of how the 230 00:07:31,950 --> 00:07:29,950 shoulders are getting older and perhaps 231 00:07:34,100 --> 00:07:31,960 how complicated they are could you just 232 00:07:36,480 --> 00:07:34,110 sort of put this in a big picture for me 233 00:07:38,220 --> 00:07:36,490 we won't know exactly what's wrong with 234 00:07:39,930 --> 00:07:38,230 this particular this it's called a 235 00:07:41,940 --> 00:07:39,940 hybrid driver it's it's essentially a 236 00:07:43,650 --> 00:07:41,950 power switch we won't know for sure 237 00:07:45,420 --> 00:07:43,660 until we get that box out when we send 238 00:07:47,400 --> 00:07:45,430 it down to our malfunction lab for 239 00:07:49,470 --> 00:07:47,410 detailed analysis but we know the powers 240 00:07:51,450 --> 00:07:49,480 not getting through and so there's a 241 00:07:53,310 --> 00:07:51,460 shorter and open something like that and 242 00:07:55,680 --> 00:07:53,320 inside that box and we'll go do it 243 00:07:56,880 --> 00:07:55,690 complete forensics on it as far as you 244 00:07:58,770 --> 00:07:56,890 know the work we're getting old no it's 245 00:08:00,540 --> 00:07:58,780 it's a machine and occasionally machines 246 00:08:03,330 --> 00:08:00,550 break and and this this time we had a 247 00:08:05,490 --> 00:08:03,340 failure in a in a switching box and and 248 00:08:08,160 --> 00:08:05,500 so no I mean it's just part of the 249 00:08:10,590 --> 00:08:08,170 business well yeah we go to great 250 00:08:12,330 --> 00:08:10,600 lengths to test various systems but this 251 00:08:14,100 --> 00:08:12,340 one this one just failed on us and so 252 00:08:15,600 --> 00:08:14,110 with it that's where we are these things 253 00:08:18,870 --> 00:08:15,610 in addition to active switches they also 254 00:08:20,070 --> 00:08:18,880 act as fuses effectively and so same 255 00:08:21,840 --> 00:08:20,080 kind of thing it doesn't mean that that 256 00:08:23,760 --> 00:08:21,850 hybrid driver itself was the cause it 257 00:08:25,800 --> 00:08:23,770 could have been the victim so to speak 258 00:08:27,120 --> 00:08:25,810 so some other circuitry opened up put a 259 00:08:28,860 --> 00:08:27,130 little high spike a current in there and 260 00:08:31,170 --> 00:08:28,870 this this guy popped off and and did 261 00:08:32,250 --> 00:08:31,180 what it was supposed to do so we really 262 00:08:34,320 --> 00:08:32,260 need to wait and get in there and see 263 00:08:35,610 --> 00:08:34,330 but but no you know this kind of I don't 264 00:08:37,770 --> 00:08:35,620 want to say it happens all the time but 265 00:08:40,320 --> 00:08:37,780 these are typical electronics failures 266 00:08:42,450 --> 00:08:40,330 and and nothing in there that indicates 267 00:08:43,770 --> 00:08:42,460 anything with age a life or your age of 268 00:08:45,330 --> 00:08:43,780 components or anything like that nothing 269 00:08:47,280 --> 00:08:45,340 nothing to make us suspect that how long 270 00:08:49,730 --> 00:08:47,290 does this buck spin working or in there 271 00:08:52,220 --> 00:08:49,740 do you have any idea how old it is 272 00:08:53,750 --> 00:08:52,230 oh gosh I don't know what question on 273 00:08:57,860 --> 00:08:53,760 this particular box don't know I will 274 00:08:59,780 --> 00:08:57,870 have to get you that hi Clara Moskowitz 275 00:09:01,550 --> 00:08:59,790 with space comm and can you give us an 276 00:09:05,600 --> 00:09:01,560 idea of how this slip might affect the 277 00:09:07,130 --> 00:09:05,610 135 launch date you want to take that 278 00:09:09,889 --> 00:09:07,140 role out for them well let's see 279 00:09:13,160 --> 00:09:09,899 Atlantis is due to roll out of the of 280 00:09:14,990 --> 00:09:13,170 the OPF on the on the 10th over the 281 00:09:18,079 --> 00:09:15,000 Vehicle Assembly Building and out to the 282 00:09:19,760 --> 00:09:18,089 pad on the 20th of this month and so if 283 00:09:21,170 --> 00:09:19,770 we if we launch by the 8th that's 284 00:09:22,820 --> 00:09:21,180 probably okay if we're a little bit 285 00:09:25,100 --> 00:09:22,830 after that then it may be a slight 286 00:09:27,620 --> 00:09:25,110 impact Atlantis's roller and roll out 287 00:09:29,210 --> 00:09:27,630 date the key there is having enough time 288 00:09:31,430 --> 00:09:29,220 to turn the launchpad around from one 289 00:09:33,139 --> 00:09:31,440 launch to the next roll out to deal with 290 00:09:35,480 --> 00:09:33,149 any kind of damage we may have had from 291 00:09:37,010 --> 00:09:35,490 the previous launch typically booked 292 00:09:39,290 --> 00:09:37,020 keep eight days I think this allows us 293 00:09:40,940 --> 00:09:39,300 10 something like that so you know it's 294 00:09:42,290 --> 00:09:40,950 it's it's kind of thing where it's 295 00:09:43,820 --> 00:09:42,300 getting kind of close but right now 296 00:09:45,740 --> 00:09:43,830 we're not worried about it right now on 297 00:09:51,680 --> 00:09:45,750 paper the Atlantis mission looks 298 00:09:54,019 --> 00:09:51,690 perfectly fine what can you tell us 299 00:09:55,670 --> 00:09:54,029 about congresswoman giffords I mentioned 300 00:09:56,510 --> 00:09:55,680 that the cruise families were heading 301 00:09:59,060 --> 00:09:56,520 home 302 00:10:00,350 --> 00:09:59,070 what would her status be see I don't 303 00:10:01,670 --> 00:10:00,360 have any specific details on her 304 00:10:03,710 --> 00:10:01,680 particular travel plans you'd have to 305 00:10:05,120 --> 00:10:03,720 contact her staff and office but but 306 00:10:06,710 --> 00:10:05,130 from a family perspective I know we 307 00:10:09,260 --> 00:10:06,720 worked the details today with the crew 308 00:10:10,550 --> 00:10:09,270 office to tell them that there was no 309 00:10:12,319 --> 00:10:10,560 launch attempt that said that there was 310 00:10:14,480 --> 00:10:12,329 a need to keep the families in town from 311 00:10:16,030 --> 00:10:14,490 a travel perspective so the know they're 312 00:10:23,290 --> 00:10:16,040 free to make their own plans to go home 313 00:10:27,550 --> 00:10:26,530 J Barbary with NBC can you think of any 314 00:10:32,170 --> 00:10:27,560 scenario 315 00:10:33,820 --> 00:10:32,180 launch before the 8th yeah no that's 316 00:10:35,800 --> 00:10:33,830 that's kind of why we decided we talked 317 00:10:38,079 --> 00:10:35,810 last night we were kind of still hope 318 00:10:39,670 --> 00:10:38,089 holding some hope that we had some time 319 00:10:41,889 --> 00:10:39,680 when we looked at the need to actually 320 00:10:43,960 --> 00:10:41,899 go after the box itself that kind of set 321 00:10:46,690 --> 00:10:43,970 the timeline to say with that retest 322 00:10:48,220 --> 00:10:46,700 required we could potentially go a 323 00:10:50,320 --> 00:10:48,230 little bit earlier than then but there 324 00:10:53,079 --> 00:10:50,330 was no need to try to hold on hope to 325 00:10:54,699 --> 00:10:53,089 have Atlas have some problem or go push 326 00:10:56,260 --> 00:10:54,709 them to make them come off the range for 327 00:10:58,120 --> 00:10:56,270 a schedule that we weren't really sure 328 00:10:59,230 --> 00:10:58,130 of yet so no we were that's why we're 329 00:11:00,970 --> 00:10:59,240 ready to say we're not going to be going 330 00:11:09,329 --> 00:11:00,980 earlier than the 8th but we're not sure 331 00:11:15,579 --> 00:11:11,290 bill Harmon if he has two quick 332 00:11:17,019 --> 00:11:15,589 questions for Mike Moses if I know the 333 00:11:19,780 --> 00:11:17,029 8th in a date it's just you know earlier 334 00:11:22,030 --> 00:11:19,790 than target but then I'm confused about 335 00:11:24,220 --> 00:11:22,040 the 9th that's not available is it as it 336 00:11:25,389 --> 00:11:24,230 stands today because you'd be in dock in 337 00:11:27,190 --> 00:11:25,399 the same time so you so if you went on 338 00:11:28,600 --> 00:11:27,200 the 8th you'd skip a day to the 10th if 339 00:11:30,220 --> 00:11:28,610 you didn't get off yeah so I've learned 340 00:11:31,840 --> 00:11:30,230 after three years to be careful what I 341 00:11:33,819 --> 00:11:31,850 tell you guys so I could tell you right 342 00:11:35,230 --> 00:11:33,829 now yes right now we we on paper say 343 00:11:38,440 --> 00:11:35,240 that's not a good date but we say that 344 00:11:40,360 --> 00:11:38,450 because if we launched on time on the 345 00:11:42,639 --> 00:11:40,370 8th and added the two mission extension 346 00:11:44,079 --> 00:11:42,649 days that we want to on-orbit we would 347 00:11:47,530 --> 00:11:44,089 then be undocking on the same day that 348 00:11:48,880 --> 00:11:47,540 the Soyuz 25 s on docks so there's 349 00:11:50,650 --> 00:11:48,890 nothing to say that we can decide we 350 00:11:53,139 --> 00:11:50,660 don't we'd rather launch on the night 351 00:11:54,460 --> 00:11:53,149 then not use plus 2 and only use one of 352 00:11:55,990 --> 00:11:54,470 those 2 days in which case we just 353 00:11:58,329 --> 00:11:56,000 deconflict it in the nights now a good 354 00:12:00,040 --> 00:11:58,339 day to go we're not thinking that's what 355 00:12:01,990 --> 00:12:00,050 we're gonna do but all that thinking was 356 00:12:03,280 --> 00:12:02,000 based on before we knew we might be 357 00:12:04,870 --> 00:12:03,290 really seriously thinking about 358 00:12:06,069 --> 00:12:04,880 launching on that day so now that we 359 00:12:08,019 --> 00:12:06,079 know we're seriously headed into that 360 00:12:09,280 --> 00:12:08,029 conflict we're gonna go talk one of the 361 00:12:11,410 --> 00:12:09,290 big things I need to wait till tomorrow 362 00:12:13,030 --> 00:12:11,420 to talk to our Russian counterparts in 363 00:12:14,500 --> 00:12:13,040 our station counterparts to find out 364 00:12:16,240 --> 00:12:14,510 truly what that does to the timeline so 365 00:12:18,040 --> 00:12:16,250 yeah we kind of on paper say the night's 366 00:12:19,810 --> 00:12:18,050 not a good day but but don't hold us to 367 00:12:21,069 --> 00:12:19,820 that we could easily decide we want to 368 00:12:22,750 --> 00:12:21,079 rearrange the mission a little bit and 369 00:12:24,760 --> 00:12:22,760 make the ninth a good day thanks ed for 370 00:12:26,290 --> 00:12:24,770 Mike Leinbach could you just give us 371 00:12:27,639 --> 00:12:26,300 days when the box comes out when you 372 00:12:28,810 --> 00:12:27,649 expect to have the new and out I assume 373 00:12:29,920 --> 00:12:28,820 it comes out tomorrow the new one goes 374 00:12:31,569 --> 00:12:29,930 in Tuesday or something or maybe 375 00:12:33,730 --> 00:12:31,579 tomorrow could you give us a little 376 00:12:35,260 --> 00:12:33,740 detail on why the retest is so 377 00:12:36,519 --> 00:12:35,270 complicated with those nine systems what 378 00:12:39,309 --> 00:12:36,529 sort of things you have to do 379 00:12:40,809 --> 00:12:39,319 to go through that process but help us 380 00:12:42,999 --> 00:12:40,819 explain why it takes two days thanks 381 00:12:44,410 --> 00:12:43,009 sure well the box on paper right now the 382 00:12:46,179 --> 00:12:44,420 box will come out tomorrow you know 383 00:12:47,800 --> 00:12:46,189 again we'll send it down our malfunction 384 00:12:50,199 --> 00:12:47,810 lab for detail inspection the new box 385 00:12:51,970 --> 00:12:50,209 goes in on Tuesday and of course as we 386 00:12:53,439 --> 00:12:51,980 work through this this tentative plan 387 00:12:55,299 --> 00:12:53,449 that we have in front of us here you 388 00:12:56,799 --> 00:12:55,309 know it work execution is going to 389 00:12:58,960 --> 00:12:56,809 dictate the exact timelines but that 390 00:13:00,519 --> 00:12:58,970 that's generally it and then after that 391 00:13:02,379 --> 00:13:00,529 we get into the retest Tuesday night 392 00:13:04,090 --> 00:13:02,389 Wednesday that kind of timeframe and 393 00:13:07,119 --> 00:13:04,100 it's going to be a full two days of 394 00:13:08,679 --> 00:13:07,129 retest and I can read you the various 395 00:13:10,329 --> 00:13:08,689 systems I wrote them down so I wouldn't 396 00:13:11,519 --> 00:13:10,339 forget any exhilarate our units 397 00:13:13,780 --> 00:13:11,529

--> 00:13:18,709 boilers main propulsion systems orbital 401 00:13:22,960 --> 00:13:20,449 maneuvering systems spatial domain 402 00:13:25,239 --> 00:13:22,970 engines and orbiter flight controls and 403 00:13:27,249 --> 00:13:25,249 any time you break a connection to a box 404 00:13:28,960 --> 00:13:27,259 like this you essentially invalidate all 405 00:13:31,239 --> 00:13:28,970 the testing we did up to that point you 406 00:13:33,340 --> 00:13:31,249 know you could take the tact of saying 407 00:13:34,989 --> 00:13:33,350 well all you're doing is replacing the 408 00:13:36,720 --> 00:13:34,999 Box everything downstream and that box 409 00:13:39,129 --> 00:13:36,730 should be fine well that's true but our 410 00:13:40,929 --> 00:13:39,139 requirements are the way we do business 411 00:13:42,819 --> 00:13:40,939 is whenever we break a connection we go 412 00:13:44,410 --> 00:13:42,829 back and retest it that's just the 413 00:13:46,329 --> 00:13:44,420 prudent thing to do and the way our 414 00:13:48,040 --> 00:13:46,339 requirements are said and so we have to 415 00:13:51,090 --> 00:13:48,050 retest every one of those those nine 416 00:13:52,809 --> 00:13:51,100 systems the details within those systems 417 00:13:55,720 --> 00:13:52,819 you know you could probably write a 418 00:13:57,610 --> 00:13:55,730 thesis on how many individual tests 419 00:14:03,579 --> 00:13:57,620 there are within those nine systems and 420 00:14:07,480 --> 00:14:03,589 that's why it takes so long it's a next 421 00:14:11,799 --> 00:14:07,490 oh hi Robert Perlman with collec 422 00:14:14,889 --> 00:14:11,809 space.com I think for Mike Moses given 423 00:14:16,600 --> 00:14:14,899 that you have the time now and if it's 424 00:14:19,600 --> 00:14:16,610 necessary or not I don't know are you 425 00:14:21,929 --> 00:14:19,610 gonna have any teams look at the at the 426 00:14:24,069 --> 00:14:21,939 ohms the right ohms pod in terms of the 427 00:14:26,889 --> 00:14:24,079 slight pressure differential that was 428 00:14:28,119 --> 00:14:26,899 seen during during the count yeah no I 429 00:14:32,079 --> 00:14:28,129 don't think there's any plans to do that 430 00:14:34,329 --> 00:14:32,089 really what that was was a creep in the 431 00:14:36,069 --> 00:14:34,339 regulator so leakage that goes through 432 00:14:37,960 --> 00:14:36,079 the regulator down into the downstream 433 00:14:40,239 --> 00:14:37,970 components we had already known about 434 00:14:42,879 --> 00:14:40,249 that condition pre-flight it was really 435 00:14:44,949 --> 00:14:42,889 just a confluence of events of of the 436 00:14:46,509 --> 00:14:44,959 time it sat in lockup it creeped in bit 437 00:14:49,059 --> 00:14:46,519 flipped up just enough to trip the limit 438 00:14:50,710 --> 00:14:49,069 the the action we took to equalize the 439 00:14:52,690 --> 00:14:50,720 pressure seemed fine 440 00:14:54,220 --> 00:14:52,700 I don't think there's any plans to do to 441 00:14:55,570 --> 00:14:54,230 do anything other than maybe some more 442 00:14:57,460 --> 00:14:55,580 data reviews to make sure there wasn't 443 00:14:59,020 --> 00:14:57,470 anything else going on there but no no 444 00:15:05,170 --> 00:14:59,030 no targets to go out for anything in the 445 00:15:08,530 --> 00:15:05,180 home system todd halvorson Florida today 446 00:15:11,020 --> 00:15:08,540 with one for each mic for Mike Moses 447 00:15:14,260 --> 00:15:11,030 could you just remind us why you don't 448 00:15:16,870 --> 00:15:14,270 like to do too undocking operations on 449 00:15:19,600 --> 00:15:16,880 the same day and for Mike Leinbach could 450 00:15:22,060 --> 00:15:19,610 you kind of give us a little information 451 00:15:25,180 --> 00:15:22,070 on the work environment the technicians 452 00:15:28,360 --> 00:15:25,190 will have in front of them in the app 453 00:15:32,890 --> 00:15:28,370 compartment and it's pretty cramped as I 454 00:15:34,980 --> 00:15:32,900 recall and what are your what would do 455 00:15:40,690 --> 00:15:34,990 to make sure you do no harm 456 00:15:43,410 --> 00:15:40,700 let's see on the on the undocking really 457 00:15:45,430 --> 00:15:43,420 comes down to crew workload and shifting 458 00:15:48,070 --> 00:15:45,440 especially when we're dealing with a 459 00:15:50,200 --> 00:15:48,080 Russian vehicle and a stay on shuttle 460 00:15:51,580 --> 00:15:50,210 vehicle the the sleep shifts required 461 00:15:53,470 --> 00:15:51,590 for each of those are going to be pretty 462 00:15:55,150 --> 00:15:53,480 drastically different so you know the 463 00:15:57,250 --> 00:15:55,160 Russians are gonna the Soyuz crew is 464 00:15:59,320 --> 00:15:57,260 going to be undocking and within a day 465 00:16:00,940 --> 00:15:59,330 coming back into to deorbit and land so 466 00:16:02,710 --> 00:16:00,950 they need to be on the right sleep shift 467 00:16:04,510 --> 00:16:02,720 so that they're well-rested and able to 468 00:16:06,250 --> 00:16:04,520 execute that event whereas our shuttle 469 00:16:08,020 --> 00:16:06,260 crew was on a sleep shift that set them 470 00:16:09,400 --> 00:16:08,030 up for their launch and is slowly 471 00:16:11,560 --> 00:16:09,410 phasing to protect them for their 472 00:16:13,810 --> 00:16:11,570 landing which I think I haven't looked 473 00:16:15,790 --> 00:16:13,820 at the details but but based on where we 474 00:16:17,290 --> 00:16:15,800 were knowing that we're delaying that's 475 00:16:18,820 --> 00:16:17,300 gonna start to start to head out a face 476 00:16:20,920 --> 00:16:18,830 from each other and so we're probably 477 00:16:22,810 --> 00:16:20,930 gonna have a decent little sleep shift 478 00:16:25,120 --> 00:16:22,820 for the crew which could be a problem 479 00:16:26,980 --> 00:16:25,130 just in general for us but so we 480 00:16:29,110 --> 00:16:26,990 basically on a crew workday on that 481 00:16:30,460 --> 00:16:29,120 given day having both crews trying to to 482 00:16:32,440 --> 00:16:30,470 work to two separate work schedules 483 00:16:33,790 --> 00:16:32,450 wouldn't really work very well a lot of 484 00:16:35,470 --> 00:16:33,800 activities have to happen both for a 485 00:16:36,790 --> 00:16:35,480 shuttle undocking in a Soyuz undocking 486 00:16:40,060 --> 00:16:36,800 and to try to do them on the same day 487 00:16:41,770 --> 00:16:40,070 would be quite a challenge well it's a 488 00:16:43,810 --> 00:16:41,780 tight on the on the question about the 489 00:16:46,000 --> 00:16:43,820 work and the after you know the the box 490 00:16:48,340 --> 00:16:46,010 itself is in avionics Bay number five 491 00:16:50,200 --> 00:16:48,350 which is just inside the door so the 492 00:16:52,570 --> 00:16:50,210 work itself to replace the box is really 493 00:16:55,270 --> 00:16:52,580 really quite easy relatively speaking 494 00:16:57,280 --> 00:16:55,280 and access is good we'd put in the entry 495 00:16:59,920 --> 00:16:57,290 level platforms and maybe one one set 496 00:17:01,150 --> 00:16:59,930 below there but then we have to put in 497 00:17:03,100 --> 00:17:01,160 the full set in order to get all the 498 00:17:05,559 --> 00:17:03,110 retest to get to the various 499 00:17:07,240 --> 00:17:05,569 and items that we need to retest and and 500 00:17:08,829 --> 00:17:07,250 from that perspective it's the same as 501 00:17:09,939 --> 00:17:08,839 closing out the after every time I mean 502 00:17:12,640 --> 00:17:09,949 we'll have an engineer we'll have a 503 00:17:14,949 --> 00:17:12,650 technician a quality inspector both NASA 504 00:17:17,110 --> 00:17:14,959 and USA if necessary for a particular 505 00:17:19,270 --> 00:17:17,120 function so it you know to me it's it's 506 00:17:21,039 --> 00:17:19,280 it's well it's standard work is just 507 00:17:22,990 --> 00:17:21,049 unfortunate happened to us in countdown 508 00:17:26,380 --> 00:17:23,000 it's getting all this attention we do 509 00:17:27,850 --> 00:17:26,390 this stuff all the time I say all the 510 00:17:30,669 --> 00:17:27,860 time whenever we have a failure we do it 511 00:17:36,360 --> 00:17:30,679 and and so that the work itself is 512 00:17:41,169 --> 00:17:38,980 carry fybel houston public radio on 513 00:17:43,390 --> 00:17:41,179 behalf of my audience which is very 514 00:17:45,640 --> 00:17:43,400 general and doesn't speak acronym can 515 00:17:48,039 --> 00:17:45,650 you just describe normally normal 516 00:17:50,830 --> 00:17:48,049 function this box what it does 517 00:17:52,570 --> 00:17:50,840 downstream does it provide power for all 518 00:17:54,580 --> 00:17:52,580 those systems you need to retest or just 519 00:17:57,220 --> 00:17:54,590 can you in simple terms lay out why this 520 00:17:59,500 --> 00:17:57,230 isn't necessary yes so it's you could 521 00:18:01,600 --> 00:17:59,510 think of it as in your house wiring it's 522 00:18:02,950 --> 00:18:01,610 not the primary fuse box on the outside 523 00:18:05,020 --> 00:18:02,960 your house but it would be the 524 00:18:06,070 --> 00:18:05,030 equivalent of if you had like in your 525 00:18:08,590 --> 00:18:06,080 garage or in your laundry room a 526 00:18:10,299 --> 00:18:08,600 breakout box that kind of a subpanel so 527 00:18:12,730 --> 00:18:10,309 it's effectively one of our sub panels 528 00:18:14,230 --> 00:18:12,740 that's taking the main power we call 529 00:18:16,690 --> 00:18:14,240 this a load control assembly and it's an 530 00:18:18,640 --> 00:18:16,700 affluent roll assembly there's three of 531 00:18:20,230 --> 00:18:18,650 them in the aft compartment that take 532 00:18:23,530 --> 00:18:20,240 our three main orbiter buses and switch 533 00:18:24,940 --> 00:18:23,540 power to all the functions one good way 534 00:18:26,860 --> 00:18:24,950 to think about how many systems this 535 00:18:28,930 --> 00:18:26,870 touch is most of the systems in the aft 536 00:18:31,180 --> 00:18:28,940 compartment are redundant and most of 537 00:18:34,240 --> 00:18:31,190 them are at least in terms of critical 538 00:18:36,039 --> 00:18:34,250 flight control functions have have two 539 00:18:37,480 --> 00:18:36,049 levels of redundancy on them so that 540 00:18:38,500 --> 00:18:37,490 means they have multiple power feeds 541 00:18:41,260 --> 00:18:38,510 going to them and we're about to 542 00:18:42,669 --> 00:18:41,270 disconnect one of those power feeds to 543 00:18:44,620 --> 00:18:42,679 verify that we reconnected that power 544 00:18:45,789 --> 00:18:44,630 feed correctly we have to go test that 545 00:18:47,560 --> 00:18:45,799 item again to make sure it's now 546 00:18:50,080 --> 00:18:47,570 receiving power from from the source 547 00:18:52,240 --> 00:18:50,090 we're basically gonna disconnect a wire 548 00:18:53,470 --> 00:18:52,250 at the fuse box and we can't test right 549 00:18:54,909 --> 00:18:53,480 there we have to go down to the the 550 00:18:56,500 --> 00:18:54,919 light at the other end of the wire and 551 00:18:58,870 --> 00:18:56,510 make sure that that light comes back on 552 00:19:00,250 --> 00:18:58,880 again so if that if that helps in a 553 00:19:03,640 --> 00:19:00,260 simplified way it's effectively a 554 00:19:06,130 --> 00:19:03,650 subpanel fuse box it's a power switching 555 00:19:07,539 --> 00:19:06,140 we call it a power switching because we 556 00:19:09,640 --> 00:19:07,549 have the ability in the cockpit to turn 557 00:19:10,840 --> 00:19:09,650 that power and if we lost the primary 558 00:19:12,700 --> 00:19:10,850 power we could switch it over to 559 00:19:14,980 --> 00:19:12,710 alternate power so we use low voltage 560 00:19:16,220 --> 00:19:14,990 power in this box to switch those power 561 00:19:17,690 --> 00:19:16,230 feeds around 562 00:19:21,279 --> 00:19:17,700 and so that's why we call it a switching 563 00:19:25,609 --> 00:19:21,289 box but it's effectively a fuse box 564 00:19:27,289 --> 00:19:25,619 powering the you know the hydraulics the 565 00:19:28,759 --> 00:19:27,299 mechanicals that we were talking about 566 00:19:31,220 --> 00:19:28,769 on Friday it's it's more than that 567 00:19:33,830 --> 00:19:31,230 correct yes the APU heaters are one of 568 00:19:36,799 --> 00:19:33,840 probably 70 or 80 things that go through 569 00:19:39,169 --> 00:19:36,809 this box I know some of the systems on 570 00:19:41,149 --> 00:19:39,179 there are ohms valve so in the ohm 571 00:19:43,099 --> 00:19:41,159 system some of the valve power goes 572 00:19:44,720 --> 00:19:43,109 through this box and so we're about to 573 00:19:46,310 --> 00:19:44,730 go take that down you need to go verify 574 00:19:49,190 --> 00:19:46,320 that that valve still has proper power 575 00:19:51,470 --> 00:19:49,200 for functionality the there's reaction 576 00:19:53,419 --> 00:19:51,480 control drivers in the RCS system which 577 00:19:55,310 --> 00:19:53,429 provide power and command to the Jets to 578 00:19:57,710 --> 00:19:55,320 fire there's main engine commands that 579 00:20:00,139 --> 00:19:57,720 go through there so a lot of things that 580 00:20:01,820 --> 00:20:00,149 besides just this APU in fact this ap is 581 00:20:03,769 --> 00:20:01,830 probably just want a tiny little thing 582 00:20:14,239 --> 00:20:03,779 that goes through there we know how to 583 00:20:17,419 --> 00:20:14,249 test the APU again now Donna line one 584 00:20:19,879 --> 00:20:17,429 from USA Today do you have any sense 585 00:20:22,609 --> 00:20:19,889 about when the astronauts will come back 586 00:20:24,979 --> 00:20:22,619 and what they're gonna be doing in the 587 00:20:26,210 --> 00:20:24,989 meantime let's see in them in the 588 00:20:29,119 --> 00:20:26,220 meantime well let me start with the 589 00:20:30,769 --> 00:20:29,129 first one like Mike said we'd reset and 590 00:20:32,629 --> 00:20:30,779 effectively start launch countdown over 591 00:20:34,580 --> 00:20:32,639 again so when we do pick a new launch 592 00:20:35,930 --> 00:20:34,590 date in the next couple days all the 593 00:20:37,940 --> 00:20:35,940 schedules are reset and the crew will 594 00:20:39,139 --> 00:20:37,950 come down at the normal time four or 595 00:20:40,729 --> 00:20:39,149 five days I actually don't remember 596 00:20:42,259 --> 00:20:40,739 exactly when they do come down but 597 00:20:45,529 --> 00:20:42,269 they'll come down at the normal time 598 00:20:47,269 --> 00:20:45,539 before a launch period so we don't plan 599 00:20:48,470 --> 00:20:47,279 to be in this kind of what if we're not 600 00:20:50,330 --> 00:20:48,480 really sure when we're gonna launch and 601 00:20:52,759 --> 00:20:50,340 sneak the qurían and suddenly go launch 602 00:20:54,109 --> 00:20:52,769 it'll be a pretty cut-and-dry this is 603 00:20:55,879 --> 00:20:54,119 our new target date go reset all your 604 00:20:56,930 --> 00:20:55,889 schedules and March to that date we're 605 00:20:59,779 --> 00:20:56,940 just not ready to make that decision 606 00:21:01,190 --> 00:20:59,789 today in the meantime the the crews 607 00:21:03,019 --> 00:21:01,200 going to basically kind of go back into 608 00:21:05,210 --> 00:21:03,029 the training they will stay in 609 00:21:06,529 --> 00:21:05,220 quarantine I think if we launch on the 610 00:21:07,820 --> 00:21:06,539 8th they could come out of quarantine 611 00:21:09,680 --> 00:21:07,830 today but have to go right back in 612 00:21:11,479 --> 00:21:09,690 tomorrow so there's no real point to 613 00:21:13,930 --> 00:21:11,489 that so they'll stay in quarantine back 614 00:21:16,279 --> 00:21:13,940 in Houston I know that the teams are 615 00:21:17,930 --> 00:21:16,289 working to set up some ascent sim 616 00:21:19,340 --> 00:21:17,940 training probably on Tuesday or 617 00:21:20,869 --> 00:21:19,350 Wednesday so they'll start some 618 00:21:22,430 --> 00:21:20,879 refresher training whenever we go for 619 00:21:24,139 --> 00:21:22,440 about a week it's good to let them have 620 00:21:25,489 --> 00:21:24,149 a chance to get back in the simulator 621 00:21:26,629 --> 00:21:25,499 and work through the normal processes 622 00:21:28,789 --> 00:21:26,639 and they'll probably have some 623 00:21:29,750 --> 00:21:28,799 standalone training a lot of what they 624 00:21:31,970 --> 00:21:29,760 do is kind of we call it 625 00:21:33,290 --> 00:21:31,980 free time but the crews are unbelievably 626 00:21:34,880 --> 00:21:33,300 dedicated they don't do anything in 627 00:21:36,500 --> 00:21:34,890 their free time other than study their 628 00:21:38,390 --> 00:21:36,510 checklists and practice their procedures 629 00:21:39,980 --> 00:21:38,400 so I don't think they're gonna go jump 630 00:21:41,180 --> 00:21:39,990 in the pool and do any VA training but I 631 00:21:43,550 --> 00:21:41,190 bet you they dry run through the 632 00:21:44,680 --> 00:21:43,560 timelines at their desk and review what 633 00:21:47,030 --> 00:21:44,690 they're supposed to be doing rehearse 634 00:21:50,840 --> 00:21:47,040 they put their time in to be ready to go 635 00:21:56,660 --> 00:21:54,170 I can't Kramer for spaceflight magazine 636 00:21:58,100 --> 00:21:56,670 for Mike Leinbach I think um can you 637 00:22:00,380 --> 00:21:58,110 tell us a little bit about the testing 638 00:22:02,180 --> 00:22:00,390 you did on this unit before the launch 639 00:22:07,490 --> 00:22:02,190 to ensure that it was good to go 640 00:22:09,620 --> 00:22:07,500 and on STS 70 I believe what was it 641 00:22:11,060 --> 00:22:09,630 exactly the same problem that you found 642 00:22:12,410 --> 00:22:11,070 or was it a different problem within 643 00:22:14,360 --> 00:22:12,420 that box thank you 644 00:22:15,860 --> 00:22:14,370 well the testing leading up to the 645 00:22:18,380 --> 00:22:15,870 countdown is Mike described the other 646 00:22:20,750 --> 00:22:18,390 day a lot of the times what we what we 647 00:22:24,020 --> 00:22:20,760 take credit for is the on-orbit success 648 00:22:26,330 --> 00:22:24,030 or failure of a system and so this 649 00:22:29,330 --> 00:22:26,340 particular box not not every function 650 00:22:33,140 --> 00:22:29,340 was tested in the OPF we do take credit 651 00:22:34,520 --> 00:22:33,150 for on-orbit on over it operations but 652 00:22:36,170 --> 00:22:34,530 everything seemed to be working just 653 00:22:38,660 --> 00:22:36,180 fine and how the failure occurred we 654 00:22:42,770 --> 00:22:38,670 just don't know yet and what was your 655 00:22:45,410 --> 00:22:42,780 part I'm sorry on STS 70 you said you 656 00:22:48,500 --> 00:22:45,420 swapped this box out before I wonder if 657 00:22:50,090 --> 00:22:48,510 the failure in that box is the same as 658 00:22:52,940 --> 00:22:50,100 what you suspect now where was it at 659 00:22:54,590 --> 00:22:52,950 different I don't know I don't know yeah 660 00:22:56,930 --> 00:22:54,600 I don't think we got that level of 661 00:22:58,970 --> 00:22:56,940 detail we know we took the box out and 662 00:23:00,920 --> 00:22:58,980 and therefore that creates the full 663 00:23:02,450 --> 00:23:00,930 retest of all those systems I mentioned 664 00:23:04,160 --> 00:23:02,460 what the particular failure was back 665 00:23:06,860 --> 00:23:04,170 then I don't remember we'll have to get 666 00:23:08,150 --> 00:23:06,870 that for you chances are it was not this 667 00:23:09,860 --> 00:23:08,160 particular failure because there are 668 00:23:13,370 --> 00:23:09,870 dozens and dozens and dozens of 669 00:23:15,650 --> 00:23:13,380 functions that go through this box this 670 00:23:19,850 --> 00:23:15,660 box replacement box fails do you have 671 00:23:22,640 --> 00:23:19,860 another one after that thanks boy 672 00:23:24,560 --> 00:23:22,650 if the replacement fails no we didn't 673 00:23:27,330 --> 00:23:24,570 were not going that way that the 674 00:23:29,100 --> 00:23:27,340 replacement is going to be great 675 00:23:31,470 --> 00:23:29,110 and that is you know the team has built 676 00:23:33,600 --> 00:23:31,480 into the timeline once we do have the 677 00:23:35,850 --> 00:23:33,610 box out of retesting and checking of the 678 00:23:38,669 --> 00:23:35,860 circuitry to verify that that box was 679 00:23:40,019 --> 00:23:38,679 the failed component so you know 680 00:23:41,789 --> 00:23:40,029 capacitance testing on the upstream and 681 00:23:43,230 --> 00:23:41,799 downstream components we kind of already 682 00:23:44,310 --> 00:23:43,240 verified heater functionality but 683 00:23:46,289 --> 00:23:44,320 they'll probably go in with breakout 684 00:23:47,489 --> 00:23:46,299 boxes and and double-check all that to 685 00:23:49,049 --> 00:23:47,499 ensure that there is no downstream 686 00:23:51,419 --> 00:23:49,059 wiring damage that might have been a 687 00:23:52,769 --> 00:23:51,429 cause to caused this break this box to 688 00:23:54,930 --> 00:23:52,779 go so that we don't put another one in 689 00:23:56,940 --> 00:23:54,940 there and blow it too so that'll be part 690 00:23:58,799 --> 00:23:56,950 of the normal test planning before we go 691 00:24:05,399 --> 00:23:58,809 put the new box in place definitely be 692 00:24:06,269 --> 00:24:05,409 doing it Sentinel from Mike Moses I just 693 00:24:09,799 --> 00:24:06,279 wanted a little bit of a clarification 694 00:24:13,470 --> 00:24:09,809 on the Soyuz undocking complication 695 00:24:15,029 --> 00:24:13,480 since 134 can have 14 15 or 16 days 696 00:24:18,619 --> 00:24:15,039 you're essentially trying to preserve a 697 00:24:21,480 --> 00:24:18,629 three-day window on the other end here 698 00:24:24,570 --> 00:24:21,490 not necessarily we're basically trying 699 00:24:25,739 --> 00:24:24,580 to preserve those two extension days we 700 00:24:27,989 --> 00:24:25,749 know ahead of time 701 00:24:30,299 --> 00:24:27,999 we're very valuable for the station in 702 00:24:32,190 --> 00:24:30,309 order to have get ahead tasks so we knew 703 00:24:34,529 --> 00:24:32,200 pre-flight we wanted to add those two 704 00:24:37,440 --> 00:24:34,539 days you could almost say we are we are 705 00:24:40,019 --> 00:24:37,450 99% ready to call this a 16-day mission 706 00:24:41,879 --> 00:24:40,029 rather than a 14-day mission but we 707 00:24:44,220 --> 00:24:41,889 didn't want to commit to them just yet 708 00:24:46,499 --> 00:24:44,230 until we got in orbit and evaluated 709 00:24:48,359 --> 00:24:46,509 other conditions like how the crew did 710 00:24:50,460 --> 00:24:48,369 how they're doing on rendezvous how 711 00:24:52,230 --> 00:24:50,470 they're adapting to being in space make 712 00:24:53,489 --> 00:24:52,240 sure there's no sleep shift issues the 713 00:24:55,710 --> 00:24:53,499 original plan was it was gonna be a 714 00:24:57,119 --> 00:24:55,720 piece of cake sleep shift so adding 715 00:24:58,739 --> 00:24:57,129 those plus two we're gonna be a pretty 716 00:25:00,269 --> 00:24:58,749 no brainer we'll sit down and look at 717 00:25:02,519 --> 00:25:00,279 all the new math and see where we're at 718 00:25:04,169 --> 00:25:02,529 the act of staying up two more days now 719 00:25:05,789 --> 00:25:04,179 might be a little more stress on the 720 00:25:07,259 --> 00:25:05,799 crew if they are having to do a big 721 00:25:08,669 --> 00:25:07,269 sleep shift and we might decide that 722 00:25:10,080 --> 00:25:08,679 that's not the right thing to do anymore 723 00:25:12,119 --> 00:25:10,090 which would then tell us we don't need 724 00:25:13,619 --> 00:25:12,129 to cover so many days of a launch window 725 00:25:15,810 --> 00:25:13,629 and we could drop a day off that mission 726 00:25:17,340 --> 00:25:15,820 so yeah it's kind of it's kind of what 727 00:25:19,470 --> 00:25:17,350 you said but it's a few more factors 728 00:25:20,159 --> 00:25:19,480 than that - one of the reasons why we 729 00:25:24,899 --> 00:25:20,169 need little more time to evaluate 730 00:25:26,940 --> 00:25:24,909 exactly what the right decision is yes 731 00:25:28,710 --> 00:25:26,950 yeah well with right now the conflict of 732 00:25:30,899 --> 00:25:28,720 why we wouldn't launch May 9th is 733 00:25:32,999 --> 00:25:30,909 because on the 16th today that would be 734 00:25:37,019 --> 00:25:33,009 undocking actually that's not that's not 735 00:25:38,430 --> 00:25:37,029 the 16th take that it's on the second 736 00:25:39,940 --> 00:25:38,440 day of docked operations second 737 00:25:42,669 --> 00:25:39,950 additional day docked operations 738 00:25:44,169 --> 00:25:42,679 but okay but it would affect the 739 00:25:45,639 --> 00:25:44,179 consequence of having a secure day-long 740 00:25:48,370 --> 00:25:45,649 mission coming what's what the undocking 741 00:25:50,019 --> 00:25:48,380 is on the same day yeah I know it's 742 00:25:54,759 --> 00:25:50,029 confusing without our calendar I don't 743 00:25:56,529 --> 00:25:54,769 have one either look at the panel CERN 744 00:25:58,029 --> 00:25:56,539 and right how far can you push this 745 00:26:01,060 --> 00:25:58,039 mission this mission not to four feet 746 00:26:03,340 --> 00:26:01,070 the next one well as Mike said you know 747 00:26:05,740 --> 00:26:03,350 we know that the eighth ninth 10th is 748 00:26:07,029 --> 00:26:05,750 probably about the same not too much of 749 00:26:08,500 --> 00:26:07,039 an impact beyond that we'll have to look 750 00:26:10,000 --> 00:26:08,510 pretty close so we're getting very close 751 00:26:11,919 --> 00:26:10,010 to being an impact to the next mission 752 00:26:13,029 --> 00:26:11,929 we're not quite there yet but that's one 753 00:26:15,549 --> 00:26:13,039 of the things that teams will take a 754 00:26:17,620 --> 00:26:15,559 close look at one of the consequences of 755 00:26:19,389 --> 00:26:17,630 our of us coming to the end of the 756 00:26:22,360 --> 00:26:19,399 program is we no longer have you know 757 00:26:24,279 --> 00:26:22,370 multiple teams able to do the jobs we're 758 00:26:25,810 --> 00:26:24,289 down on our resources and our staffing 759 00:26:27,970 --> 00:26:25,820 so we need to make sure we know what 760 00:26:29,590 --> 00:26:27,980 this launch schedule is and then we'll 761 00:26:31,180 --> 00:26:29,600 let the next team take a look at what 762 00:26:32,799 --> 00:26:31,190 they need resource wise and make sure we 763 00:26:34,870 --> 00:26:32,809 don't have to move that launch date to 764 00:26:36,639 --> 00:26:34,880 avoid some conflicts really I think what 765 00:26:37,810 --> 00:26:36,649 we're gonna find is the pad turnaround 766 00:26:39,789 --> 00:26:37,820 that Mike talked about is really gonna 767 00:26:41,440 --> 00:26:39,799 be our driver of once we launch this 768 00:26:43,240 --> 00:26:41,450 vehicle go out and assess the damage to 769 00:26:44,950 --> 00:26:43,250 the pad how long it'll take to repair 770 00:26:46,840 --> 00:26:44,960 and be ready to receive the next mission 771 00:26:49,899 --> 00:26:46,850 on paper right now it looks like we're 772 00:26:51,639 --> 00:26:49,909 okay but if we go too much past the 9th 773 00:26:53,889 --> 00:26:51,649 or the 10th and we might need to add a 774 00:26:55,149 --> 00:26:53,899 couple extra days so I don't want to 775 00:26:56,560 --> 00:26:55,159 tell you no impact but I don't want to 776 00:27:01,029 --> 00:26:56,570 tell you definite impact it's it's 777 00:27:03,039 --> 00:27:01,039 getting close the saint-jacques from the 778 00:27:06,460 --> 00:27:03,049 Houston Chronicle just wanted to know 779 00:27:08,080 --> 00:27:06,470 about the quarantine can you explain to 780 00:27:10,389 --> 00:27:08,090 us again why astronauts have to be on 781 00:27:13,570 --> 00:27:10,399 quarantine and where are they going to 782 00:27:15,639 --> 00:27:13,580 be quarantined in Houston also I 783 00:27:17,320 --> 00:27:15,649 understand they're allowed I think one 784 00:27:19,840 --> 00:27:17,330 visitor a day for a certain amount of 785 00:27:22,419 --> 00:27:19,850 hours does that visitor have to come to 786 00:27:23,769 --> 00:27:22,429 the quarantine area or are there 787 00:27:27,639 --> 00:27:23,779 exceptions being made for certain 788 00:27:29,440 --> 00:27:27,649 astronauts like commander Mark Kelly we 789 00:27:31,529 --> 00:27:29,450 lock them in a box and we don't let 790 00:27:35,289 --> 00:27:31,539 anybody ever see him again 791 00:27:37,570 --> 00:27:35,299 yeah the quarantine rules are pretty 792 00:27:39,250 --> 00:27:37,580 straightforward I don't remember the 793 00:27:41,200 --> 00:27:39,260 exact number of days before mission but 794 00:27:44,649 --> 00:27:41,210 the purpose is to basically stay away 795 00:27:46,029 --> 00:27:44,659 from any any contagious illnesses that 796 00:27:48,759 --> 00:27:46,039 would then take a few days to show up 797 00:27:50,549 --> 00:27:48,769 and manifest and so the quarantine 798 00:27:52,539 --> 00:27:50,559 basically is the crew reports to a 799 00:27:53,860 --> 00:27:52,549 quarantine facility that's on site at 800 00:27:56,170 --> 00:27:53,870 the Johnson Space Center 801 00:27:57,400 --> 00:27:56,180 astronaut crew quarters it's a it's a 802 00:28:00,190 --> 00:27:57,410 pretty nice building conference room 803 00:28:02,740 --> 00:28:00,200 facilities training facilities a gym and 804 00:28:04,150 --> 00:28:02,750 and sleeping quarters and then they have 805 00:28:06,040 --> 00:28:04,160 contact a lot more than just one person 806 00:28:07,720 --> 00:28:06,050 for an hour a day there's a whole list 807 00:28:09,070 --> 00:28:07,730 of folks who are on the approved contact 808 00:28:10,870 --> 00:28:09,080 list as long as you've passed your 809 00:28:12,670 --> 00:28:10,880 physical and are cleared with what we 810 00:28:14,110 --> 00:28:12,680 call a where we used to call a primary 811 00:28:15,910 --> 00:28:14,120 contact physical I think we've changed 812 00:28:17,590 --> 00:28:15,920 the name of it recently but it's 813 00:28:18,820 --> 00:28:17,600 effectively if you're in primary contact 814 00:28:21,370 --> 00:28:18,830 with the crew you also have to show 815 00:28:24,700 --> 00:28:21,380 you're in good health really the the 816 00:28:26,020 --> 00:28:24,710 biggest restriction is in terms of young 817 00:28:28,990 --> 00:28:26,030 children that's those are the ones that 818 00:28:30,460 --> 00:28:29,000 really we have trouble for those of us 819 00:28:31,930 --> 00:28:30,470 who have very young children they bring 820 00:28:33,640 --> 00:28:31,940 home all kinds of nasty bugs and you get 821 00:28:35,230 --> 00:28:33,650 sick when a short notice you can tell 822 00:28:36,940 --> 00:28:35,240 I'm coughing I am I am currently not 823 00:28:40,780 --> 00:28:36,950 allowed on primary contact with the crew 824 00:28:41,740 --> 00:28:40,790 by choice if nothing else but but it's 825 00:28:43,090 --> 00:28:41,750 that kind of thing so they'll go back 826 00:28:44,860 --> 00:28:43,100 into quarantine at the crew facility 827 00:28:46,360 --> 00:28:44,870 they'll be able to visit with family 828 00:28:48,040 --> 00:28:46,370 members who are cleared and through 829 00:28:49,510 --> 00:28:48,050 their through their physical process 830 00:28:51,100 --> 00:28:49,520 they'll start meeting with all their 831 00:28:52,990 --> 00:28:51,110 trainers and all their flight directors 832 00:28:54,760 --> 00:28:53,000 and the training crews and they'll get 833 00:28:56,200 --> 00:28:54,770 back in and do their job it'll be a lot 834 00:28:57,850 --> 00:28:56,210 like they were just a couple days before 835 00:28:59,740 --> 00:28:57,860 they came down here not a lot of 836 00:29:02,470 --> 00:28:59,750 difference for him yeah they'll be at 837 00:29:04,680 --> 00:29:02,480 Johnson Space Center know they'll be 838 00:29:06,669 --> 00:29:04,690 yeah they'll stay in the crew quarters 839 00:29:07,810 --> 00:29:06,679 but they don't know they're not 840 00:29:09,250 --> 00:29:07,820 restricted and locked in the building 841 00:29:10,270 --> 00:29:09,260 like I was joking at the beginning you 842 00:29:11,530 --> 00:29:10,280 know they'll leave and they'll go over 843 00:29:12,820 --> 00:29:11,540 to the trainers and they'll run in the 844 00:29:14,560 --> 00:29:12,830 training facility if they needed to go 845 00:29:15,790 --> 00:29:14,570 out to the NBL they could so they're not 846 00:29:16,990 --> 00:29:15,800 they're not locked down they just don't 847 00:29:22,780 --> 00:29:17,000 go home and sleep at night in their own 848 00:29:24,430 --> 00:29:22,790 bed at home annaleigh he lofty ambitions 849 00:29:26,980 --> 00:29:24,440 and Chapman magazine one more 850 00:29:29,890 --> 00:29:26,990 clarification on the crew when you're 851 00:29:32,410 --> 00:29:29,900 working a delay how long does the delay 852 00:29:34,299 --> 00:29:32,420 have to out how long do you have to know 853 00:29:36,130 --> 00:29:34,309 the delay is going to be before you send 854 00:29:37,810 --> 00:29:36,140 the crew home does it have to be at 855 00:29:40,120 --> 00:29:37,820 least five days because that's what they 856 00:29:42,040 --> 00:29:40,130 would normally spend here yeah that 857 00:29:45,100 --> 00:29:42,050 factors into it really it's kind of more 858 00:29:47,140 --> 00:29:45,110 just of a logistics if we knew that that 859 00:29:48,730 --> 00:29:47,150 we'd be picking up a launch day such 860 00:29:49,900 --> 00:29:48,740 that they'd go home turn right back 861 00:29:51,520 --> 00:29:49,910 around and have to fly back here the 862 00:29:53,560 --> 00:29:51,530 next day we'd probably give them the 863 00:29:55,540 --> 00:29:53,570 choice to do that if they wanted to it's 864 00:29:57,160 --> 00:29:55,550 not like they can go back and and repack 865 00:29:58,990 --> 00:29:57,170 their suitcase and do a lot of other 866 00:30:01,570 --> 00:29:59,000 things so there's not a lot of drive for 867 00:30:04,360 --> 00:30:01,580 them to return home on a short trip but 868 00:30:06,230 --> 00:30:04,370 then again it is a chance to go back to 869 00:30:08,570 --> 00:30:06,240 your home environment and 870 00:30:10,040 --> 00:30:08,580 more comfort little more contact you're 871 00:30:11,300 --> 00:30:10,050 not you're not stuck here at the Kennedy 872 00:30:12,890 --> 00:30:11,310 Space Center you're least stuck at the 873 00:30:15,200 --> 00:30:12,900 Johnson Space Center which is a little 874 00:30:16,760 --> 00:30:15,210 closer to your home but it really comes 875 00:30:18,290 --> 00:30:16,770 down to a trade-in and the crew office 876 00:30:20,090 --> 00:30:18,300 the crew management office and and the 877 00:30:21,620 --> 00:30:20,100 program talks about the likelihood we 878 00:30:23,510 --> 00:30:21,630 had those conversations this morning and 879 00:30:25,040 --> 00:30:23,520 I let him know pretty clearly that that 880 00:30:27,140 --> 00:30:25,050 we weren't going to be looking at a 881 00:30:28,310 --> 00:30:27,150 Thursday Friday launch attempt and there 882 00:30:29,690 --> 00:30:28,320 was no need to keep the guys here they 883 00:30:35,120 --> 00:30:29,700 could head home and we'll bring them 884 00:30:37,910 --> 00:30:35,130 back when we're ready Mark Boucher 885 00:30:40,580 --> 00:30:37,920 spacecraft for Mike Moses are there any 886 00:30:43,550 --> 00:30:40,590 dates between the 8th and the 15th that 887 00:30:45,770 --> 00:30:43,560 you have ruled out not specifically no 888 00:30:47,210 --> 00:30:45,780 those all look pretty good to us and a 889 00:30:49,730 --> 00:30:47,220 follow-up question for Michael wingback 890 00:30:54,950 --> 00:30:49,740 have you ever had a failure with the 891 00:30:56,510 --> 00:30:54,960 hybrid drivers before I don't know the 892 00:30:58,010 --> 00:30:56,520 answer to that I'll have to get I have 893 00:30:59,570 --> 00:30:58,020 to get to that data do we hear that and 894 00:31:00,680 --> 00:30:59,580 I know a telecoms last night yeah I know 895 00:31:02,570 --> 00:31:00,690 failure to it we've definitely had 896 00:31:04,640 --> 00:31:02,580 hybrid driver failures before whether 897 00:31:08,320 --> 00:31:04,650 it's this is a civic hybrid driver I 898 00:31:12,770 --> 00:31:10,820 Jean macoco both talking space could you 899 00:31:14,960 --> 00:31:12,780 give us an idea on how big the LCA is as 900 00:31:18,890 --> 00:31:14,970 a bigger than a breadbox or something 901 00:31:21,980 --> 00:31:18,900 like that what it's 40 to 50 pounds it's 902 00:31:25,130 --> 00:31:21,990 probably on this sort of scale maybe a 903 00:31:26,900 --> 00:31:25,140 little bit bigger and and to get it into 904 00:31:28,580 --> 00:31:26,910 the avionics babies a little bit of a 905 00:31:31,070 --> 00:31:28,590 trick because you kind of kind of wiggle 906 00:31:33,200 --> 00:31:31,080 it up there and then attach it and so we 907 00:31:36,290 --> 00:31:33,210 have a system of rails that we actually 908 00:31:38,240 --> 00:31:36,300 use to to guide the Box in place to help 909 00:31:41,210 --> 00:31:38,250 the technicians as they're bolting it in 910 00:31:43,460 --> 00:31:41,220 and so we have to put the rail set in as 911 00:31:44,960 --> 00:31:43,470 well and that's just sort of a safety 912 00:31:46,700 --> 00:31:44,970 precaution I mean the guys probably 913 00:31:48,590 --> 00:31:46,710 could muscle it into place but it's a 914 00:31:50,630 --> 00:31:48,600 heck of a lot easier with that rail so 915 00:31:53,570 --> 00:31:50,640 yeah it's 40 to 50 pounds probably 48 916 00:32:01,310 --> 00:31:53,580 something like that and a little tricky 917 00:32:03,750 --> 00:32:03,360 there's actually this I didn't think of 918 00:32:13,260 --> 00:32:03,760 it 919 00:32:15,690 --> 00:32:13,270 ken is Apollo sorry I can't grammar 920 00:32:17,340 --> 00:32:15,700 again for spaceflight magazine for 921 00:32:19,290 --> 00:32:17,350 either Mike I'm not sure these these 922 00:32:22,290 --> 00:32:19,300 hydrazine fuel lines can you tell me how 923 00:32:25,530 --> 00:32:22,300 thick they are and what kind of pressure 924 00:32:27,330 --> 00:32:25,540 they can withstand please oh I don't 925 00:32:30,270 --> 00:32:27,340 know that well my head yeah I don't know 926 00:32:32,460 --> 00:32:30,280 what an APU fuel line I could speculate 927 00:32:34,260 --> 00:32:32,470 about probably wrong I don't I don't 928 00:32:37,530 --> 00:32:34,270 know either Ken I'm sorry we'll get you 929 00:32:40,470 --> 00:32:37,540 that right the concern is if if it's 930 00:32:42,660 --> 00:32:40,480 thaws and expands that the lines could 931 00:32:44,520 --> 00:32:42,670 good so we have a lot of testing and 932 00:32:46,740 --> 00:32:44,530 we've we've done that out or white sands 933 00:32:48,780 --> 00:32:46,750 test facility in New Mexico a whole 934 00:32:50,670 --> 00:32:48,790 bunch of testing to show that the lines 935 00:32:53,910 --> 00:32:50,680 we can basically withstand a single 936 00:32:55,410 --> 00:32:53,920 freeze-thaw cycle but beyond that you 937 00:32:57,630 --> 00:32:55,420 then kind of really start to worry about 938 00:32:59,670 --> 00:32:57,640 the integrity of the system we've shown 939 00:33:01,650 --> 00:32:59,680 in that testing that the plug of 940 00:33:03,540 --> 00:33:01,660 hydrazine ice that would form would kind 941 00:33:04,920 --> 00:33:03,550 of move up and down the line so that 942 00:33:06,270 --> 00:33:04,930 that's not really the problem but 943 00:33:07,980 --> 00:33:06,280 there's a lot of valves and plumbing and 944 00:33:09,840 --> 00:33:07,990 piping and if you if you were in one of 945 00:33:11,430 --> 00:33:09,850 those regions where you had a nice ball 946 00:33:13,200 --> 00:33:11,440 formation you'd worry about extra stress 947 00:33:15,660 --> 00:33:13,210 in that region which is hard to model 948 00:33:17,430 --> 00:33:15,670 and test and therefore we try our very 949 00:33:18,930 --> 00:33:17,440 best and that's why this rule allows us 950 00:33:20,670 --> 00:33:18,940 or does not allow us to launch with a 951 00:33:22,110 --> 00:33:20,680 failed heater we want to make sure we 952 00:33:23,130 --> 00:33:22,120 have good integrity of those systems so 953 00:33:26,000 --> 00:33:23,140 we don't ever have to get into a 954 00:33:30,360 --> 00:33:29,100 Doug deco Knox magazine since you 955 00:33:33,180 --> 00:33:30,370 introduced that part of the 956 00:33:36,090 --> 00:33:33,190 functionality of the LCA is as a fusing 957 00:33:37,440 --> 00:33:36,100 system doesn't that allow for the 958 00:33:40,110 --> 00:33:37,450 possibility that something upstream of 959 00:33:42,270 --> 00:33:40,120 that fuse is malfunctioning and if so 960 00:33:45,330 --> 00:33:42,280 what would concern you the most yeah 961 00:33:46,980 --> 00:33:45,340 most definitely we've effectively kind 962 00:33:48,960 --> 00:33:46,990 of cleared the wiring outside the box by 963 00:33:50,460 --> 00:33:48,970 doing the the thermostat response tests 964 00:33:51,900 --> 00:33:50,470 and the measurements of the current 965 00:33:53,130 --> 00:33:51,910 there they're going to go back and do 966 00:33:55,560 --> 00:33:53,140 that again with a different set of 967 00:33:57,180 --> 00:33:55,570 equipment once the box is out but 968 00:33:59,370 --> 00:33:57,190 there's a lot of internal components 969 00:34:01,560 --> 00:33:59,380 inside that LCA that takes the power 970 00:34:03,270 --> 00:34:01,570 from the from the the connectors down to 971 00:34:04,710 --> 00:34:03,280 the right hybrid driver over to the 972 00:34:06,690 --> 00:34:04,720 common ground hybrid drivers there's a 973 00:34:09,090 --> 00:34:06,700 lot of a wiring path in there that could 974 00:34:10,290 --> 00:34:09,100 be the problem you know a little little 975 00:34:11,010 --> 00:34:10,300 piece of debris or something like that a 976 00:34:14,430 --> 00:34:11,020 blown 977 00:34:16,530 --> 00:34:14,440 have what could have been what caused 978 00:34:18,930 --> 00:34:16,540 this just a solder connection that came 979 00:34:20,700 --> 00:34:18,940 open really could be the problem and so 980 00:34:22,500 --> 00:34:20,710 we'll take that box out and then we'll 981 00:34:23,820 --> 00:34:22,510 confirm that the failures inside that 982 00:34:25,440 --> 00:34:23,830 box and then that'll give us a 983 00:34:27,720 --> 00:34:25,450 confidence that we know it might not be 984 00:34:29,520 --> 00:34:27,730 the hybrid driver itself these why the 985 00:34:31,290 --> 00:34:29,530 problem happened but the problems also 986 00:34:36,570 --> 00:34:31,300 inside the box as well if that makes 987 00:34:39,869 --> 00:34:36,580 sense okay well last questions that need 988 00:34:42,000 --> 00:34:39,879 answering now okay not see any hands up 989 00:34:44,010 --> 00:34:42,010 we do have some new video of some of the 990 00:34:46,109 --> 00:34:44,020 activities going on at the pad this 991 00:34:47,099 --> 00:34:46,119 morning it's not any of course you've 992 00:34:49,109 --> 00:34:47,109 heard them saying nothing about the 993 00:34:50,909 --> 00:34:49,119 actual chain Network since that hasn't 994 00:34:53,040 --> 00:34:50,919 happened yet but at least is some fresh 995 00:34:55,139 --> 00:34:53,050 video from today so we playing that 996 00:34:58,349 --> 00:34:55,149 after the briefing of course to follow 997 00:35:00,599 --> 00:34:58,359 along online go to wws AG up slash 998 00:35:02,580 --> 00:35:00,609 shuttle tell you about the any of the
