1 00:00:03,750 --> 00:00:02,149 good afternoon and welcome back to 2 00:00:06,230 --> 00:00:03,760 nasa's johnson space center as we 3 00:00:07,749 --> 00:00:06,240 continue to take a look at the sts-134 4 00:00:09,589 --> 00:00:07,759 mission and endeavors flight to the 5 00:00:11,350 --> 00:00:09,599 international space station there's 6 00:00:12,789 --> 00:00:11,360 going to be four space walks planned for 7 00:00:15,110 --> 00:00:12,799 this mission these will also be the 8 00:00:16,630 --> 00:00:15,120 final spacewalks ever conducted by a 9 00:00:18,470 --> 00:00:16,640 space shuttle crew so here to give us 10 00:00:20,310 --> 00:00:18,480 more details about all of that is 11 00:00:23,349 --> 00:00:20,320 allison bolinger she is the lead 12 00:00:25,509 --> 00:00:23,359 spacewalk officer for sts-134 go ahead 13 00:00:27,509 --> 00:00:25,519 thanks josh i'm very excited to be here 14 00:00:29,750 --> 00:00:27,519 today to talk about the spacewalks that 15 00:00:31,750 --> 00:00:29,760 we will be performing on the sts-134 16 00:00:33,830 --> 00:00:31,760 mission as josh mentioned we have four 17 00:00:36,069 --> 00:00:33,840 spacewalks planned on this mission they 18 00:00:38,229 --> 00:00:36,079 will occur on flight days five seven 19 00:00:39,910 --> 00:00:38,239 nine and eleven we will be utilizing 20 00:00:41,910 --> 00:00:39,920 three of endeavour's crew members to 21 00:00:43,510 --> 00:00:41,920 perform these spacewalks and each of 22 00:00:46,069 --> 00:00:43,520 these crew members brings a very unique 23 00:00:49,029 --> 00:00:46,079 experience space to our team 24 00:00:50,549 --> 00:00:49,039 our lead spacewalker ev1 is drew feustel 25 00:00:52,549 --> 00:00:50,559 drew will be wearing the suit that's 26 00:00:54,389 --> 00:00:52,559 marked with a solid red stripe drew 27 00:00:56,430 --> 00:00:54,399 comes to us with three space walks under 28 00:00:58,790 --> 00:00:56,440 his belt which he performed during the 29 00:01:00,470 --> 00:00:58,800 sts-125 mission which was the most 30 00:01:02,470 --> 00:01:00,480 recent hubble telescope servicing 31 00:01:04,229 --> 00:01:02,480 mission so this will be drew's first 32 00:01:06,230 --> 00:01:04,239 trip to the international space station 33 00:01:08,870 --> 00:01:06,240 and he will be performing spacewalks one 34 00:01:10,630 --> 00:01:08,880 two and three no stranger to spacewalk 35 00:01:13,030 --> 00:01:10,640 however i'm sorry no stranger to the 36 00:01:15,190 --> 00:01:13,040 international space station is our ev2 37 00:01:17,190 --> 00:01:15,200 crew member who will be mike fink mike 38 00:01:19,590 --> 00:01:17,200 has spent just a little over a year on 39 00:01:21,749 --> 00:01:19,600 the space station during expeditions 9 40 00:01:23,990 --> 00:01:21,759 and 18. during that time on the space 41 00:01:25,830 --> 00:01:24,000 station mike performed six space walks 42 00:01:28,070 --> 00:01:25,840 however all of those space walks were in 43 00:01:31,749 --> 00:01:28,080 the russian orlan suit so these will be 44 00:01:33,510 --> 00:01:31,759 his first spacewalks in the u.s emu he 45 00:01:36,069 --> 00:01:33,520 will be wearing the all-white suit on 46 00:01:38,390 --> 00:01:36,079 eva's 2 3 and 4. 47 00:01:40,390 --> 00:01:38,400 our ev3 crew member will be greg 48 00:01:42,469 --> 00:01:40,400 chamotov greg will be wearing the suit 49 00:01:44,310 --> 00:01:42,479 marked with the broken red stripes greg 50 00:01:46,630 --> 00:01:44,320 is also no stranger to space station he 51 00:01:47,590 --> 00:01:46,640 spent a little over six months up there 52 00:01:50,389 --> 00:01:47,600 during the 53 00:01:52,310 --> 00:01:50,399 expanding expedition 17 and 18. these 54 00:01:55,109 --> 00:01:52,320 will be his first spacewalks and he will 55 00:01:57,429 --> 00:01:55,119 be performing evas 1 and 4. 56 00:01:58,709 --> 00:01:57,439 the role of the task iv crew member or 57 00:02:00,709 --> 00:01:58,719 the person who remains inside the 58 00:02:02,550 --> 00:02:00,719 shuttle to choreograph the space walks 59 00:02:04,950 --> 00:02:02,560 will be performed by as i call it the 60 00:02:06,550 --> 00:02:04,960 odd man in or one of the three eva crew 61 00:02:08,869 --> 00:02:06,560 members who is not outside performing 62 00:02:10,630 --> 00:02:08,879 the space walk that day 63 00:02:13,270 --> 00:02:10,640 endeavors commander mark kelly will 64 00:02:15,510 --> 00:02:13,280 serve as our suit iv or the crew member 65 00:02:17,110 --> 00:02:15,520 in charge of getting the eva crew ready 66 00:02:18,790 --> 00:02:17,120 to go out the door which includes 67 00:02:21,350 --> 00:02:18,800 depressing and repressing the iss 68 00:02:23,350 --> 00:02:21,360 airlock he will be assisted by iss crew 69 00:02:24,790 --> 00:02:23,360 members paolo nespoli and ron garan to 70 00:02:27,030 --> 00:02:24,800 help with his duties 71 00:02:29,350 --> 00:02:27,040 wrapping up our eva team is endeavour's 72 00:02:31,350 --> 00:02:29,360 pilot greg box johnson i'll refer to him 73 00:02:33,509 --> 00:02:31,360 as greg i'm sorry as box so as not to 74 00:02:35,430 --> 00:02:33,519 confuse him with greg chamitov 75 00:02:40,790 --> 00:02:35,440 greg will be flying box will be flying 76 00:02:42,949 --> 00:02:40,800 the robotic arm for us on evas 2 and 4. 77 00:02:44,710 --> 00:02:42,959 another unique aspect to our mission 78 00:02:46,229 --> 00:02:44,720 will be the first time use of a new 79 00:02:48,390 --> 00:02:46,239 pre-breathe protocol which i believe you 80 00:02:50,470 --> 00:02:48,400 heard about earlier in derek's briefing 81 00:02:52,470 --> 00:02:50,480 this new protocol the protocols are 82 00:02:54,309 --> 00:02:52,480 generally used to purge the eva crew 83 00:02:56,229 --> 00:02:54,319 member's body of nitrogen prior to 84 00:02:58,070 --> 00:02:56,239 egressing to perform an eva to avoid 85 00:03:00,550 --> 00:02:58,080 getting decompression sickness or the 86 00:03:02,710 --> 00:03:00,560 bends on currently our pre-flight plan 87 00:03:05,350 --> 00:03:02,720 on evas 1 2 and 4 88 00:03:07,350 --> 00:03:05,360 is to utilize the nominal eva kampa 89 00:03:09,350 --> 00:03:07,360 pre-booth protocol which is the protocol 90 00:03:13,270 --> 00:03:09,360 in which the crew members are isolated 91 00:03:15,990 --> 00:03:13,280 in the iss airlock at 10.2 psi overnight 92 00:03:18,550 --> 00:03:16,000 for eva 3 however we will be we will be 93 00:03:21,110 --> 00:03:18,560 utilizing this new aisle or in-suit 94 00:03:23,270 --> 00:03:21,120 light exercise pre-breathe protocol this 95 00:03:25,910 --> 00:03:23,280 protocol starts the morning of the eva 96 00:03:27,830 --> 00:03:25,920 and looks very similar to the morning of 97 00:03:29,270 --> 00:03:27,840 camp out day of eva with a slight 98 00:03:30,869 --> 00:03:29,280 exception that i'll talk about and show 99 00:03:32,869 --> 00:03:30,879 you a video of 100 00:03:35,270 --> 00:03:32,879 the crew members will begin the day by 101 00:03:38,309 --> 00:03:35,280 donning oxygen masks we will depress the 102 00:03:40,070 --> 00:03:38,319 airlock down to 10.2 psi this will be 103 00:03:41,750 --> 00:03:40,080 with the two eevee crew members and the 104 00:03:44,550 --> 00:03:41,760 three ivy crew members who will assist 105 00:03:45,990 --> 00:03:44,560 in donning it's at this time at 10.2 psi 106 00:03:47,990 --> 00:03:46,000 that the crew members will don their 107 00:03:51,270 --> 00:03:48,000 suits then we will repress the airlock 108 00:03:53,350 --> 00:03:51,280 back up to 14.7 psi they will perform 109 00:03:54,630 --> 00:03:53,360 the nominal 50 minute in-suit resting 110 00:03:56,789 --> 00:03:54,640 pre-breathe which you've seen with the 111 00:03:58,710 --> 00:03:56,799 camp protocol and then for this new 112 00:04:01,350 --> 00:03:58,720 aisle protocol we will add an additional 113 00:04:05,830 --> 00:04:01,360 50 minutes of light in suit exercise so 114 00:04:09,670 --> 00:04:08,070 alright so this is video that was taken 115 00:04:11,670 --> 00:04:09,680 during one of our training runs at the 116 00:04:13,509 --> 00:04:11,680 neutral buoyancy lab 117 00:04:15,190 --> 00:04:13,519 on the left side we've got 118 00:04:16,789 --> 00:04:15,200 crew member mike fink on the right side 119 00:04:19,270 --> 00:04:16,799 we have drew feustel and you can see 120 00:04:21,270 --> 00:04:19,280 they're performing the light exercise 121 00:04:23,270 --> 00:04:21,280 as we as just as you could see it's 122 00:04:25,670 --> 00:04:23,280 extremely light exercise something that 123 00:04:28,230 --> 00:04:25,680 i fondly refer to as a slow motion hokey 124 00:04:29,990 --> 00:04:28,240 pokey so during the 50 minutes of this 125 00:04:31,510 --> 00:04:30,000 exercise the crew members will be doing 126 00:04:33,430 --> 00:04:31,520 these slight flutter kicks with their 127 00:04:35,110 --> 00:04:33,440 legs for four minutes they will rest for 128 00:04:36,790 --> 00:04:35,120 a minute they will exercise again for 129 00:04:39,430 --> 00:04:36,800 four minutes they will rest for another 130 00:04:41,830 --> 00:04:39,440 minute and we will continue this for the 131 00:04:43,590 --> 00:04:41,840 next 50 minutes as derek mentioned there 132 00:04:44,790 --> 00:04:43,600 are quite a few benefits to this new 133 00:04:46,150 --> 00:04:44,800 protocol 134 00:04:47,510 --> 00:04:46,160 the first one is that the crew members 135 00:04:49,189 --> 00:04:47,520 are not isolated in the airlock 136 00:04:51,270 --> 00:04:49,199 overnight so they can have a normal 137 00:04:53,110 --> 00:04:51,280 night before eva and a normal morning of 138 00:04:55,030 --> 00:04:53,120 eva when they first wake up the crew 139 00:04:56,629 --> 00:04:55,040 members spend less time on the oxygen 140 00:04:59,270 --> 00:04:56,639 masks which can be uncomfortable for 141 00:05:01,350 --> 00:04:59,280 some crew members and we are also 142 00:05:04,070 --> 00:05:01,360 expecting this protocol to use less of 143 00:05:05,670 --> 00:05:04,080 station's precious resource of oxygen so 144 00:05:07,590 --> 00:05:05,680 there's been quite a bit of planning on 145 00:05:09,110 --> 00:05:07,600 the ground that has gone into preparing 146 00:05:11,350 --> 00:05:09,120 this protocol for flight so i'm very 147 00:05:14,070 --> 00:05:11,360 excited to see it in action on eva 3 and 148 00:05:15,430 --> 00:05:14,080 possibly eva4 149 00:05:16,629 --> 00:05:15,440 with that i'll go ahead and start 150 00:05:17,909 --> 00:05:16,639 detailing 151 00:05:20,469 --> 00:05:17,919 the different tasks that we'll be 152 00:05:22,950 --> 00:05:20,479 performing on the evas we will start out 153 00:05:25,029 --> 00:05:22,960 eva 1 with our highest eva mission 154 00:05:26,629 --> 00:05:25,039 priority which is to retrieve two 155 00:05:28,390 --> 00:05:26,639 experiments that are currently located 156 00:05:29,510 --> 00:05:28,400 on the s3 truss 157 00:05:32,310 --> 00:05:29,520 these experiments are called the 158 00:05:35,270 --> 00:05:32,320 materials iss experiments or missy 7a 159 00:05:37,590 --> 00:05:35,280 and 7b these experiments were installed 160 00:05:40,710 --> 00:05:37,600 during the sts-129 mission on the 161 00:05:42,629 --> 00:05:40,720 express logistics carrier or elc 2. we 162 00:05:43,990 --> 00:05:42,639 will retrieve these experiments and then 163 00:05:45,830 --> 00:05:44,000 take them to the payload bay for the 164 00:05:47,430 --> 00:05:45,840 return home while we're in the payload 165 00:05:49,590 --> 00:05:47,440 bay we'll retrieve a new missy 8 166 00:05:52,390 --> 00:05:49,600 experiment which drew will install in 167 00:05:53,990 --> 00:05:52,400 the spot where missy 7a was located 168 00:05:56,629 --> 00:05:54,000 the middle part of this eva will be 169 00:05:58,710 --> 00:05:56,639 dedicated to setting up for eva2's 170 00:06:00,950 --> 00:05:58,720 ammonia refill of the cooling system out 171 00:06:03,110 --> 00:06:00,960 on the p6 truss this is the cooling 172 00:06:04,469 --> 00:06:03,120 system that cools the batteries for the 173 00:06:07,670 --> 00:06:04,479 solar arrays out there it's also 174 00:06:10,230 --> 00:06:07,680 referred to as the pvtcs or photovoltaic 175 00:06:11,909 --> 00:06:10,240 photovoltaic thermal control system this 176 00:06:13,510 --> 00:06:11,919 system has been experienced a slight 177 00:06:15,350 --> 00:06:13,520 leak over the past few years and needs 178 00:06:17,350 --> 00:06:15,360 to be refilled with ammonia in order for 179 00:06:19,189 --> 00:06:17,360 it to keep properly functioning 180 00:06:21,430 --> 00:06:19,199 this task isn't as straightforward as it 181 00:06:23,350 --> 00:06:21,440 seems since the p6 truss is isolated 182 00:06:25,590 --> 00:06:23,360 from the primary ammonia tank located on 183 00:06:27,510 --> 00:06:25,600 the p1 side of the truss we will need to 184 00:06:29,749 --> 00:06:27,520 hook up a series of jumpers that span 185 00:06:33,029 --> 00:06:29,759 from the p1 ammonia tank assembly all 186 00:06:34,629 --> 00:06:33,039 the way out board to the p6 truss on eva 187 00:06:36,469 --> 00:06:34,639 1 we will work on setting up those 188 00:06:38,070 --> 00:06:36,479 jumpers and venting the nitrogen pad 189 00:06:41,110 --> 00:06:38,080 that was launched inside these jumpers 190 00:06:43,270 --> 00:06:41,120 in preparation for eva2 191 00:06:45,189 --> 00:06:43,280 we'll finish up the eva by translating 192 00:06:47,270 --> 00:06:45,199 down to the lab and installing two new 193 00:06:49,510 --> 00:06:47,280 antennas in their associated octopus of 194 00:06:51,430 --> 00:06:49,520 cables these antennas will eventually 195 00:06:53,830 --> 00:06:51,440 talk wirelessly to experiments that are 196 00:07:01,749 --> 00:06:53,840 located on the express logistics carrier 197 00:07:07,670 --> 00:07:04,870 ev1 we'll start out at the airlock with 198 00:07:09,430 --> 00:07:07,680 drew feustel and greg chamitov 199 00:07:11,589 --> 00:07:09,440 both crew members will translate out to 200 00:07:13,589 --> 00:07:11,599 the starboard side of the truss 201 00:07:16,309 --> 00:07:13,599 to the elc 2 where they will start their 202 00:07:19,430 --> 00:07:16,319 work on the missy 7a and 7b experiments 203 00:07:21,589 --> 00:07:19,440 they will demate existing electrical and 204 00:07:23,350 --> 00:07:21,599 data cables they will close the the 205 00:07:24,469 --> 00:07:23,360 doors on the experiment they will 206 00:07:31,029 --> 00:07:24,479 release it and then stow it on their 207 00:07:35,189 --> 00:07:32,309 here's some footage from the neutral 208 00:07:40,230 --> 00:07:35,199 buoyancy lab of drew and greg practicing 209 00:07:43,029 --> 00:07:41,589 once they have the experiments both 210 00:07:44,790 --> 00:07:43,039 stowed on their body restraint tethers 211 00:07:46,550 --> 00:07:44,800 they will translate down to endeavour's 212 00:07:48,150 --> 00:07:46,560 payload bay 213 00:07:49,589 --> 00:07:48,160 greg will work on the starboard side of 214 00:07:51,830 --> 00:07:49,599 the payload bay drew will work on the 215 00:07:53,430 --> 00:07:51,840 port side they will work on transferring 216 00:07:54,790 --> 00:07:53,440 the missing experiments from their body 217 00:07:57,350 --> 00:07:54,800 restraint tethers to the sidewall 218 00:07:59,029 --> 00:07:57,360 carriers for the return trip home 219 00:08:00,710 --> 00:07:59,039 drew will translate aft in the payload 220 00:08:02,550 --> 00:08:00,720 bay then to retrieve the missy 8 221 00:08:03,909 --> 00:08:02,560 experiment 222 00:08:06,869 --> 00:08:03,919 both crew members will then translate 223 00:08:08,309 --> 00:08:06,879 back up to the s3 truss 224 00:08:10,309 --> 00:08:08,319 drew will translate to the top of the 225 00:08:13,189 --> 00:08:10,319 elc2 once again where he will install 226 00:08:13,990 --> 00:08:13,199 the new missy 8 you'll open the cover on 227 00:08:15,430 --> 00:08:14,000 it 228 00:08:17,670 --> 00:08:15,440 and then install two connectors 229 00:08:22,070 --> 00:08:17,680 providing data and power you also take 230 00:08:25,909 --> 00:08:24,070 meanwhile greg will work on installing a 231 00:08:27,270 --> 00:08:25,919 light on the s3 truss this is called a 232 00:08:29,430 --> 00:08:27,280 cedar light or crew equipment and 233 00:08:30,629 --> 00:08:29,440 translation aid light 234 00:08:32,469 --> 00:08:30,639 here's a photo of the light in the 235 00:08:33,990 --> 00:08:32,479 install location the light has a single 236 00:08:35,750 --> 00:08:34,000 bolt and there's a single electrical 237 00:08:36,550 --> 00:08:35,760 connector that provides power to this 238 00:08:37,990 --> 00:08:36,560 light 239 00:08:39,350 --> 00:08:38,000 once he's complete at that work site 240 00:08:42,149 --> 00:08:39,360 he'll translate a little further 241 00:08:43,589 --> 00:08:42,159 outboard to the p3 sarge or sola alpha 242 00:08:45,430 --> 00:08:43,599 rotary joint where he will work on 243 00:08:47,190 --> 00:08:45,440 reinstalling a cover that protects that 244 00:08:49,430 --> 00:08:47,200 sarge this cover was first removed 245 00:08:51,750 --> 00:08:49,440 during an increment 16 eva this cover 246 00:08:53,110 --> 00:08:51,760 has six bolts 247 00:08:54,470 --> 00:08:53,120 once complete on the starboard side of 248 00:08:55,829 --> 00:08:54,480 the truss both crew members will 249 00:08:57,590 --> 00:08:55,839 translate over to the port side of the 250 00:09:00,470 --> 00:08:57,600 truss to start setting up for that fill 251 00:09:01,910 --> 00:09:00,480 on eva2 they will demate a 16 foot long 252 00:09:03,910 --> 00:09:01,920 jumper that we have that's currently 253 00:09:05,670 --> 00:09:03,920 stowed on the p4 bulkhead they will need 254 00:09:07,829 --> 00:09:05,680 to lock the port sarge in order to do 255 00:09:09,910 --> 00:09:07,839 this greg will work on installing the 256 00:09:11,590 --> 00:09:09,920 port side of the p4 side of this jumper 257 00:09:14,949 --> 00:09:11,600 and drew will work on installing the p3 258 00:09:18,150 --> 00:09:16,230 once they have that jumper installed 259 00:09:20,710 --> 00:09:18,160 drew will translate outboard to the p5 260 00:09:22,630 --> 00:09:20,720 p6 junction where he will demate 261 00:09:24,310 --> 00:09:22,640 a fluid line he will mate it up to a 262 00:09:25,990 --> 00:09:24,320 nitrogen vent tool at this point in time 263 00:09:28,230 --> 00:09:26,000 we have a continuous pipeline running 264 00:09:30,310 --> 00:09:28,240 from p5 all the way into the p1 ammonia 265 00:09:38,389 --> 00:09:30,320 tank assembly he will vent the nitrogen 266 00:09:41,829 --> 00:09:39,910 and then he will translate outboard to 267 00:09:45,590 --> 00:09:41,839 the final jumper that runs to the p6 268 00:09:47,030 --> 00:09:45,600 pvtcs he will dema demate that jumper 269 00:09:48,790 --> 00:09:47,040 make the nitrogen vent tool and then 270 00:09:58,070 --> 00:09:48,800 once again vent the nitrogen pad from 271 00:10:01,509 --> 00:09:59,350 once we're complete with venting the 272 00:10:03,110 --> 00:10:01,519 nitrogen from the p3 p4 jumper we will 273 00:10:04,870 --> 00:10:03,120 need to demate one side of it in order 274 00:10:07,190 --> 00:10:04,880 to allow the port sarge to rotate 275 00:10:09,110 --> 00:10:07,200 between evas for power generation so 276 00:10:10,550 --> 00:10:09,120 greg will work on demating the p3 side 277 00:10:12,069 --> 00:10:10,560 of that jumper 278 00:10:13,990 --> 00:10:12,079 he will route it back over to its 279 00:10:15,590 --> 00:10:14,000 stowage panel on p4 where he will mate 280 00:10:17,430 --> 00:10:15,600 it and then he will secure the line with 281 00:10:19,350 --> 00:10:17,440 a wire tie on a handrail to ensure that 282 00:10:23,990 --> 00:10:19,360 it doesn't get caught up in the serge 283 00:10:28,710 --> 00:10:25,990 both crew members will then translate 284 00:10:30,230 --> 00:10:28,720 over to the u.s lab node 2 interface on 285 00:10:35,030 --> 00:10:30,240 the nader side there where they will set 286 00:10:39,190 --> 00:10:37,350 drew will first set up a medium bag that 287 00:10:43,269 --> 00:10:39,200 contains the two antennas as well as 288 00:10:46,310 --> 00:10:45,190 and greg will start his work on the top 289 00:10:48,150 --> 00:10:46,320 side of the lab where he will be 290 00:10:49,670 --> 00:10:48,160 removing two existing handrails and 291 00:10:51,350 --> 00:10:49,680 installing two new and hand rails that 292 00:10:52,389 --> 00:10:51,360 already have the antennas integrated on 293 00:11:01,590 --> 00:10:52,399 them 294 00:11:07,670 --> 00:11:03,670 here's a flight photo 295 00:11:09,190 --> 00:11:07,680 integrated on the handrail and here's 296 00:11:13,990 --> 00:11:09,200 some footage from the neutral buoyancy 297 00:11:17,350 --> 00:11:15,829 he's complete he will translate nader on 298 00:11:19,509 --> 00:11:17,360 the lab to help drew with their next 299 00:11:21,750 --> 00:11:19,519 task of installing this octopus of cable 300 00:11:23,110 --> 00:11:21,760 they will release a gap spanner open up 301 00:11:25,509 --> 00:11:23,120 a shield which will 302 00:11:27,590 --> 00:11:25,519 which will reveal an existing ews or 303 00:11:29,590 --> 00:11:27,600 external wireless instrumentation system 304 00:11:31,910 --> 00:11:29,600 cable which they will demate and then 305 00:11:33,670 --> 00:11:31,920 they will work on installing this new 306 00:11:35,269 --> 00:11:33,680 set of cables they have two connections 307 00:11:36,949 --> 00:11:35,279 that they need to make underneath this 308 00:11:39,030 --> 00:11:36,959 shield then they will work on routing 309 00:11:40,389 --> 00:11:39,040 the six legs of this cable 310 00:11:42,150 --> 00:11:40,399 once they've made those connections 311 00:11:43,990 --> 00:11:42,160 under the shield they'll work together 312 00:11:45,670 --> 00:11:44,000 to close it up and install the two zeus 313 00:11:46,949 --> 00:11:45,680 fasteners three zeus fasteners that hold 314 00:11:49,030 --> 00:11:46,959 it down 315 00:11:49,990 --> 00:11:49,040 they will then finish de-mating that old 316 00:11:51,990 --> 00:11:50,000 e-wiss 317 00:11:53,750 --> 00:11:52,000 cable it will be tempted in a bag to 318 00:11:56,150 --> 00:11:53,760 return inside 319 00:11:57,670 --> 00:11:56,160 they will route two lines of this cable 320 00:12:00,550 --> 00:11:57,680 up to the antennas that greg just 321 00:12:03,750 --> 00:12:02,150 it will route another two lines and 322 00:12:05,670 --> 00:12:03,760 they'll just temp stow those for future 323 00:12:06,949 --> 00:12:05,680 use 324 00:12:08,870 --> 00:12:06,959 and then they will finally install the 325 00:12:10,550 --> 00:12:08,880 final two legs of this cable into those 326 00:12:15,269 --> 00:12:10,560 e-whis antennas so that that system 327 00:12:17,990 --> 00:12:16,470 once they're complete at the work site 328 00:12:19,670 --> 00:12:18,000 greg will reinstall the gap spanner and 329 00:12:22,310 --> 00:12:19,680 work on ensuring all the tools have been 330 00:12:24,870 --> 00:12:22,320 stowed inside the medium bag to return 331 00:12:26,230 --> 00:12:24,880 back to the air lock and drew will head 332 00:12:28,389 --> 00:12:26,240 off early to translate back to the 333 00:12:30,790 --> 00:12:28,399 airlock to start more preparation work 334 00:12:34,470 --> 00:12:30,800 for the eva2 ammonia fill he will 335 00:12:36,310 --> 00:12:34,480 retrieve a few tools from the larger 336 00:12:39,910 --> 00:12:36,320 fluid quick disconnect bag which he will 337 00:12:41,750 --> 00:12:39,920 relocate to the vent tool extender bag 338 00:12:43,509 --> 00:12:41,760 he will also work on retrieving from the 339 00:12:45,110 --> 00:12:43,519 airlock a bag that contains two of the 340 00:12:47,670 --> 00:12:45,120 power jumper cables that we will be 341 00:12:49,190 --> 00:12:47,680 installing on eva3 our airlock is so 342 00:12:51,750 --> 00:12:49,200 full on eva3 that we need to 343 00:12:55,910 --> 00:12:51,760 preemptively stow these cables external 344 00:12:58,790 --> 00:12:57,430 once complete with that task both crew 345 00:13:00,389 --> 00:12:58,800 members will translate back to the 346 00:13:04,710 --> 00:13:00,399 airlock they will ingress and that 347 00:13:09,750 --> 00:13:07,110 eva2 has two main objectives the first 348 00:13:11,829 --> 00:13:09,760 of those objectives is to finish up the 349 00:13:13,990 --> 00:13:11,839 ammonia fill of the p6 cooling system 350 00:13:15,590 --> 00:13:14,000 that we set up for on eva1 once this 351 00:13:17,670 --> 00:13:15,600 fill is complete we need to vent 352 00:13:19,990 --> 00:13:17,680 residual ammonia from those lines and we 353 00:13:22,389 --> 00:13:20,000 will do this in two separate vents the 354 00:13:24,949 --> 00:13:22,399 next major task on this eva is to 355 00:13:27,990 --> 00:13:24,959 perform a re-lubrication of the port 356 00:13:29,590 --> 00:13:28,000 sarge or solar alpha rotary joint this 357 00:13:32,550 --> 00:13:29,600 preventative maintenance was first 358 00:13:34,230 --> 00:13:32,560 performed on the sts-126 mission in 359 00:13:36,629 --> 00:13:34,240 order to do this we will remove six 360 00:13:38,389 --> 00:13:36,639 protective covers over the sarge we will 361 00:13:40,710 --> 00:13:38,399 use two different styles of grease guns 362 00:13:42,550 --> 00:13:40,720 to apply a first coat of lubrication to 363 00:13:45,030 --> 00:13:42,560 the sarge we will then wait for the 364 00:13:46,550 --> 00:13:45,040 ground to rotate the starch 200 degrees 365 00:13:48,310 --> 00:13:46,560 we'll come back out apply the second 366 00:13:49,990 --> 00:13:48,320 coat of lubrication and then reinstall 367 00:13:51,750 --> 00:13:50,000 those protective covers 368 00:13:53,750 --> 00:13:51,760 while this 200 degree rotation of the 369 00:13:56,150 --> 00:13:53,760 sarge is ongoing we have a few tasks for 370 00:13:58,710 --> 00:13:56,160 the crew members to perform drew will be 371 00:14:01,269 --> 00:13:58,720 utilizing his grease gun once again to 372 00:14:02,949 --> 00:14:01,279 apply a thin coat of grease to dexter's 373 00:14:04,949 --> 00:14:02,959 latching end effector he will apply 374 00:14:07,269 --> 00:14:04,959 grease to those snares to help it 375 00:14:09,110 --> 00:14:07,279 function properly and mike will work on 376 00:14:11,750 --> 00:14:09,120 installing some stowage beams that will 377 00:14:12,790 --> 00:14:11,760 eventually hold radiator grapple bars so 378 00:14:17,350 --> 00:14:12,800 with that we can go ahead and roll the 379 00:14:20,949 --> 00:14:19,269 eva2 will start out at the airlock once 380 00:14:23,430 --> 00:14:20,959 again with crew members drew feustel and 381 00:14:24,389 --> 00:14:23,440 mike fink 382 00:14:27,110 --> 00:14:24,399 drew 383 00:14:28,790 --> 00:14:27,120 the airlock where he will retrieve the 384 00:14:31,110 --> 00:14:28,800 ventral extender bag he will still that 385 00:14:32,710 --> 00:14:31,120 in his body restraint tether 386 00:14:34,550 --> 00:14:32,720 mike will retrieve a medium bag that 387 00:14:36,550 --> 00:14:34,560 contains the tools for his port sarge 388 00:14:38,470 --> 00:14:36,560 lubrication he will translate out to the 389 00:14:40,389 --> 00:14:38,480 port sarge and set up shop out there 390 00:14:41,590 --> 00:14:40,399 with his bag 391 00:14:43,829 --> 00:14:41,600 they will then work together to 392 00:14:47,269 --> 00:14:43,839 reinstall that p3p4 jumper that was 393 00:14:50,230 --> 00:14:47,279 temporarily stowed at the end of eva1 394 00:14:51,750 --> 00:14:50,240 drew will reconnect the p3 side 395 00:14:53,670 --> 00:14:51,760 then he will translate outward to the 396 00:14:59,110 --> 00:14:53,680 midpoint of p6 where he will temporarily 397 00:15:04,230 --> 00:15:00,949 meanwhile mike will make his way back to 398 00:15:06,790 --> 00:15:04,240 the p the p1 a 500 panel which we call 399 00:15:08,150 --> 00:15:06,800 home plate this panel is is hooked up to 400 00:15:09,910 --> 00:15:08,160 the ammonia tank assembly which is a 401 00:15:11,670 --> 00:15:09,920 large box above mic it's currently set 402 00:15:13,269 --> 00:15:11,680 up for a vent configuration in a 403 00:15:15,430 --> 00:15:13,279 contingency case when they needed to 404 00:15:16,949 --> 00:15:15,440 vent the ammonia tank he will relocate 405 00:15:18,949 --> 00:15:16,959 it to a fill location which will now 406 00:15:20,870 --> 00:15:18,959 allow ammonia to flow from this ammonia 407 00:15:23,030 --> 00:15:20,880 tank outboard so at this time the ground 408 00:15:25,030 --> 00:15:23,040 will perform an initial leak check of 409 00:15:26,550 --> 00:15:25,040 the pipeline to verify everything solid 410 00:15:27,910 --> 00:15:26,560 and it looks good 411 00:15:29,350 --> 00:15:27,920 once the leak check is complete 412 00:15:31,829 --> 00:15:29,360 verifying we have a good line from the 413 00:15:34,389 --> 00:15:31,839 ammonia tank assembly out to p5 drew 414 00:15:36,710 --> 00:15:34,399 will mate a p5 p6 jumper allowing the 415 00:15:38,310 --> 00:15:36,720 ammonia to flow even further outboard 416 00:15:40,550 --> 00:15:38,320 then he will translate out to the final 417 00:15:42,389 --> 00:15:40,560 jumper where he will throw two valves 418 00:15:45,670 --> 00:15:42,399 which will allow ammonia to finally flow 419 00:15:46,949 --> 00:15:45,680 to its final destination of the p6 pvtcs 420 00:15:49,350 --> 00:15:46,959 this ammonia fill should take 421 00:15:51,269 --> 00:15:49,360 approximately 10 minutes 422 00:15:53,030 --> 00:15:51,279 during that time he will be setting up 423 00:15:54,949 --> 00:15:53,040 the vent tool extension in preparation 424 00:15:56,470 --> 00:15:54,959 for the two vents that we need to do he 425 00:15:59,430 --> 00:15:56,480 will aim the nozzle of the vent tool 426 00:16:01,110 --> 00:15:59,440 extension in a retrograde direction 427 00:16:03,110 --> 00:16:01,120 once we're complete with the fill drew 428 00:16:04,629 --> 00:16:03,120 will demate one side of this jumper and 429 00:16:07,509 --> 00:16:04,639 we'll install a cap to ensure the 430 00:16:09,350 --> 00:16:07,519 ammonia stays nicely inside that pvtcs 431 00:16:11,269 --> 00:16:09,360 then he will work on routing the ventral 432 00:16:19,269 --> 00:16:11,279 extension line inboard to set up for the 433 00:16:23,350 --> 00:16:21,269 to start the vent he will demate the p5 434 00:16:25,509 --> 00:16:23,360 jumper from its p6 male and made it up 435 00:16:27,430 --> 00:16:25,519 to the vent tool extension 436 00:16:29,430 --> 00:16:27,440 once he starts this vent it takes about 437 00:16:30,870 --> 00:16:29,440 17 minutes to vent the ammonia that's 438 00:16:35,189 --> 00:16:30,880 running from this jumper all the way 439 00:16:38,310 --> 00:16:36,790 while all of the outboard operations 440 00:16:39,350 --> 00:16:38,320 have been going on with the fill and 441 00:16:41,269 --> 00:16:39,360 vent 442 00:16:43,509 --> 00:16:41,279 mike has been working diligently at the 443 00:16:45,269 --> 00:16:43,519 port sarge to start that lubrication his 444 00:16:47,590 --> 00:16:45,279 first task is to remove the six 445 00:16:49,430 --> 00:16:47,600 protective covers over the sarge 446 00:16:51,350 --> 00:16:49,440 once he has those covers removed he will 447 00:16:53,189 --> 00:16:51,360 be using an eva camera to take some 448 00:16:55,910 --> 00:16:53,199 pictures and then he will also be using 449 00:16:58,310 --> 00:16:55,920 an eva wipe to take some samples of the 450 00:17:00,629 --> 00:16:58,320 grease that was left over from sts-126 451 00:17:02,870 --> 00:17:00,639 so folks on the ground can analyze that 452 00:17:04,789 --> 00:17:02,880 he will then make use of two grease guns 453 00:17:06,710 --> 00:17:04,799 to perform this lubrication the top left 454 00:17:08,630 --> 00:17:06,720 picture shows the j-hook nozzle grease 455 00:17:16,710 --> 00:17:08,640 gun and the top right shows the straight 456 00:17:21,350 --> 00:17:19,270 once the 17-minute vent is complete 457 00:17:23,510 --> 00:17:21,360 drew will remate the p5 jumper to its 458 00:17:25,350 --> 00:17:23,520 dummy mail on p5 and he will work on 459 00:17:33,909 --> 00:17:25,360 rerouting the vent tool extension 460 00:17:37,029 --> 00:17:35,350 this smaller jumper vent should only 461 00:17:38,549 --> 00:17:37,039 take approximately four minutes however 462 00:17:40,710 --> 00:17:38,559 it has the unique constraint that we 463 00:17:42,150 --> 00:17:40,720 need to initiate this vent during an 464 00:17:43,830 --> 00:17:42,160 eclipse pass 465 00:17:45,590 --> 00:17:43,840 so if the day night cycles do not work 466 00:17:47,830 --> 00:17:45,600 out in our favor drew will simply head 467 00:17:49,750 --> 00:17:47,840 inboard and assist mike in the port 468 00:17:52,549 --> 00:17:49,760 sarge lubrication he has his own set of 469 00:17:54,070 --> 00:17:52,559 grease guns to help out with this 470 00:17:57,029 --> 00:17:54,080 once we're done with the four minute 471 00:18:02,950 --> 00:17:57,039 vent drew will relocate this jumper to a 472 00:18:06,630 --> 00:18:04,789 and then he will work on coiling and 473 00:18:12,310 --> 00:18:06,640 stowing the ventral extension back in 474 00:18:15,750 --> 00:18:14,070 then he will stow the ventual extension 475 00:18:19,190 --> 00:18:15,760 bag on his body restraint tether and he 476 00:18:23,590 --> 00:18:20,630 now that we're complete with the ammonia 477 00:18:25,110 --> 00:18:23,600 fill we need to stow the p3p4 jumper so 478 00:18:28,230 --> 00:18:25,120 the two crew members will work together 479 00:18:30,150 --> 00:18:28,240 to install it back on its p4 stowage 480 00:18:32,630 --> 00:18:30,160 bulkhead 481 00:18:34,470 --> 00:18:32,640 and then once we verify that all 482 00:18:36,070 --> 00:18:34,480 tools tethers and crew members are 483 00:18:38,150 --> 00:18:36,080 inboard of the sarge we'll give the 484 00:18:40,870 --> 00:18:38,160 ground a go to start its 200 degree 485 00:18:42,390 --> 00:18:40,880 rotation this rotation will not be 486 00:18:44,310 --> 00:18:42,400 nearly as fast as shown here it will 487 00:18:46,710 --> 00:18:44,320 take approximately 45 minutes to do this 488 00:18:48,630 --> 00:18:46,720 200 degree rotation 489 00:18:49,990 --> 00:18:48,640 while that's ongoing drew will translate 490 00:18:51,909 --> 00:18:50,000 back to the home plate panel to 491 00:18:53,669 --> 00:18:51,919 reconfigure that jumper to the vent 492 00:18:56,950 --> 00:18:53,679 location for the ammonia tank assembly 493 00:18:58,470 --> 00:18:56,960 in a contingency case 494 00:19:00,150 --> 00:18:58,480 and then he will translate up to the 495 00:19:02,470 --> 00:19:00,160 port crew equipment aid in translation 496 00:19:03,990 --> 00:19:02,480 or ceda cart where he will retrieve a 497 00:19:05,750 --> 00:19:04,000 foot restraint he will still then in his 498 00:19:08,710 --> 00:19:05,760 body restraint tether and then translate 499 00:19:10,390 --> 00:19:08,720 to the nader side of the p1 truss 500 00:19:12,630 --> 00:19:10,400 at this time he'll start working with 501 00:19:14,230 --> 00:19:12,640 box who's inside the station flying the 502 00:19:16,230 --> 00:19:14,240 station's robotic arm which is grappled 503 00:19:17,669 --> 00:19:16,240 to dexter 504 00:19:19,750 --> 00:19:17,679 drew and box will work together to 505 00:19:21,270 --> 00:19:19,760 maneuver dexter so that drew can install 506 00:19:23,110 --> 00:19:21,280 his foot restraint and then he will work 507 00:19:24,950 --> 00:19:23,120 on installing a lens cover over the 508 00:19:28,470 --> 00:19:24,960 camera that's on 509 00:19:30,150 --> 00:19:28,480 that's on dexter's latching end effector 510 00:19:31,350 --> 00:19:30,160 he will then work on retrieving the 511 00:19:32,549 --> 00:19:31,360 straight nozzle grease gun that he 512 00:19:33,590 --> 00:19:32,559 brought with him 513 00:19:35,590 --> 00:19:33,600 and he will start performing the 514 00:19:39,510 --> 00:19:35,600 lubrication on spdm's latching and 515 00:19:42,230 --> 00:19:40,789 here's a view of what drew will be 516 00:19:43,909 --> 00:19:42,240 looking at you can see the snares 517 00:19:45,510 --> 00:19:43,919 located inside the latching defector and 518 00:19:47,510 --> 00:19:45,520 also the camera that he just installed 519 00:19:49,190 --> 00:19:47,520 the lens cover on here's some footage 520 00:19:55,110 --> 00:19:49,200 from the neutral buoyancy lab of drew 521 00:19:58,070 --> 00:19:56,630 once they're complete with the full 522 00:19:59,990 --> 00:19:58,080 lubrication 523 00:20:01,909 --> 00:20:00,000 drew will work with box to maneuver 524 00:20:09,830 --> 00:20:01,919 dexter once again so that he can utilize 525 00:20:13,190 --> 00:20:11,190 drew will then retrieve that foot 526 00:20:19,990 --> 00:20:13,200 restraint and stow it back on the port 527 00:20:23,029 --> 00:20:21,669 meanwhile mike had translated back to 528 00:20:24,950 --> 00:20:23,039 the airlock and he had stowed the 529 00:20:26,470 --> 00:20:24,960 ventual extension bag back on top of the 530 00:20:28,870 --> 00:20:26,480 airlock where it was originally located 531 00:20:30,630 --> 00:20:28,880 prior to the eva he also retrieved a 532 00:20:32,630 --> 00:20:30,640 medium bag that contained the two 533 00:20:34,870 --> 00:20:32,640 grapple bar stowage beams 534 00:20:36,630 --> 00:20:34,880 then translates to the zenith side of s1 535 00:20:38,630 --> 00:20:36,640 where he works on installing first the 536 00:20:40,710 --> 00:20:38,640 inboard grapple bar stowage beam this 537 00:20:42,390 --> 00:20:40,720 beam has two bolts and then he'll work 538 00:20:47,510 --> 00:20:42,400 on installing the outboard stowage beam 539 00:20:50,710 --> 00:20:49,029 once both crew members are complete with 540 00:20:51,990 --> 00:20:50,720 their work inboard of the sarge and the 541 00:20:53,750 --> 00:20:52,000 ground is verified that the surge 542 00:20:55,510 --> 00:20:53,760 rotation is complete both crew members 543 00:20:57,669 --> 00:20:55,520 will translate outboard to finish up the 544 00:20:59,669 --> 00:20:57,679 port sarge lubrication they will use 545 00:21:01,830 --> 00:20:59,679 their own sets of guns to apply one more 546 00:21:03,590 --> 00:21:01,840 final coat of lubrication to the sarge 547 00:21:05,830 --> 00:21:03,600 race ring then they will work together 548 00:21:07,350 --> 00:21:05,840 to reinstall the six covers that protect 549 00:21:09,110 --> 00:21:07,360 the sarge 550 00:21:11,190 --> 00:21:09,120 four of these six covers have four bolts 551 00:21:16,549 --> 00:21:11,200 apiece and two of these covers have six 552 00:21:19,350 --> 00:21:17,830 once they're complete with the cover 553 00:21:21,270 --> 00:21:19,360 install they're verified that they have 554 00:21:23,190 --> 00:21:21,280 all of their tools and tethers packed 555 00:21:24,870 --> 00:21:23,200 inside that medium bag 556 00:21:26,470 --> 00:21:24,880 they will retrieve that verify the work 557 00:21:31,029 --> 00:21:26,480 site is clear then they will translate 558 00:21:31,039 --> 00:21:41,750 and that completes eva ii 559 00:21:45,909 --> 00:21:43,990 eva3 will be spent mostly on the russian 560 00:21:47,510 --> 00:21:45,919 segment so we're very lucky to have mike 561 00:21:49,909 --> 00:21:47,520 fink with all of his vast russian 562 00:21:52,149 --> 00:21:49,919 experience performing this eva the first 563 00:21:54,870 --> 00:21:52,159 task will be to install a power and data 564 00:21:56,470 --> 00:21:54,880 grapple fixture on the russian fgb the 565 00:21:58,950 --> 00:21:56,480 power and data grapple fixture along 566 00:22:00,549 --> 00:21:58,960 with its power and data cables and a 567 00:22:02,950 --> 00:22:00,559 video signal conditioner that we will 568 00:22:04,950 --> 00:22:02,960 install next to it will allow the ssrms 569 00:22:07,270 --> 00:22:04,960 or stations robotic arm to eventually 570 00:22:09,350 --> 00:22:07,280 walk off and use this as a base 571 00:22:11,669 --> 00:22:09,360 for future use once we're complete with 572 00:22:13,510 --> 00:22:11,679 that task we will work on installing 573 00:22:15,190 --> 00:22:13,520 the two power cables that we temp stowed 574 00:22:18,070 --> 00:22:15,200 outside the airlock at the end of eva 575 00:22:19,669 --> 00:22:18,080 one we refer to these as y-jumper cables 576 00:22:21,750 --> 00:22:19,679 we have a port side cable and a 577 00:22:24,310 --> 00:22:21,760 starboard side cable these cables run 578 00:22:27,270 --> 00:22:24,320 from node one port node one forward to 579 00:22:30,149 --> 00:22:27,280 node one nader and then a node one 580 00:22:32,470 --> 00:22:30,159 afternator and then back to the fgb 581 00:22:35,110 --> 00:22:32,480 and this will provide a redundancy to 582 00:22:36,789 --> 00:22:35,120 the russian segment and its power so 583 00:22:41,350 --> 00:22:36,799 with that we can go ahead and roll eva3 584 00:22:45,510 --> 00:22:43,669 eva 3 will start out at the joint 585 00:22:47,510 --> 00:22:45,520 airlock once again with crew members 586 00:22:49,669 --> 00:22:47,520 drew feustel and mike fink drew will 587 00:22:51,190 --> 00:22:49,679 first work on relocating that power 588 00:22:56,470 --> 00:22:51,200 cable bag that he temp slowed at the end 589 00:22:59,669 --> 00:22:57,830 mike will work on retrieving a 590 00:23:01,270 --> 00:22:59,679 medium-sized bag with a crew lock bag 591 00:23:02,870 --> 00:23:01,280 inside of it and he will set up shop on 592 00:23:11,190 --> 00:23:02,880 the port side of the truss 593 00:23:14,310 --> 00:23:12,870 mike will then install a gap spanner 594 00:23:17,909 --> 00:23:14,320 that will help with the translation 595 00:23:21,029 --> 00:23:19,270 and the two crew members will work 596 00:23:23,430 --> 00:23:21,039 together to remove five pieces of 597 00:23:24,870 --> 00:23:23,440 multi-layer insulation or mli that's 598 00:23:28,149 --> 00:23:24,880 currently protecting the install 599 00:23:30,070 --> 00:23:28,159 locations for the pdgf and the vsc once 600 00:23:31,830 --> 00:23:30,080 this mli is removed they will bundle it 601 00:23:33,750 --> 00:23:31,840 together with a wire tie and then use a 602 00:23:35,510 --> 00:23:33,760 few additional wire ties to secure it to 603 00:23:37,430 --> 00:23:35,520 a handrail in the russian segment this 604 00:23:39,990 --> 00:23:37,440 mli will probably be jettisoned on a 605 00:23:41,750 --> 00:23:40,000 future russian eva 606 00:23:43,350 --> 00:23:41,760 both crew members will then translate 607 00:23:45,990 --> 00:23:43,360 back to the airlock to assist one 608 00:23:47,750 --> 00:23:46,000 another with retrieving the pdgf and its 609 00:23:49,190 --> 00:23:47,760 frame as you can see it's a fairly large 610 00:23:50,789 --> 00:23:49,200 piece of equipment so they will both be 611 00:23:52,710 --> 00:23:50,799 tethered to it and 612 00:23:55,350 --> 00:23:52,720 kind of instrument back to its install 613 00:23:56,950 --> 00:23:55,360 location on the port side of the fgb 614 00:23:58,310 --> 00:23:56,960 once they get it soft docked they will 615 00:24:01,909 --> 00:23:58,320 tighten the three feet that hold the 616 00:24:06,549 --> 00:24:03,510 then they will work on installing the 617 00:24:08,470 --> 00:24:06,559 video signal conditioner this vsc has a 618 00:24:10,230 --> 00:24:08,480 single bolt 619 00:24:12,149 --> 00:24:10,240 and then they will route three cables 620 00:24:14,070 --> 00:24:12,159 that are installed on the pdgf to this 621 00:24:15,590 --> 00:24:14,080 video signal conditioner then they will 622 00:24:17,590 --> 00:24:15,600 retrieve and route a fourth cable which 623 00:24:20,789 --> 00:24:17,600 was temporarily stowed by a previous 624 00:24:23,990 --> 00:24:22,549 once that's installed 625 00:24:25,990 --> 00:24:24,000 once all the cables are installed they 626 00:24:28,230 --> 00:24:26,000 will install a hard protective cover on 627 00:24:29,750 --> 00:24:28,240 top of the vsc so at this point in time 628 00:24:31,830 --> 00:24:29,760 that we will start work on installing 629 00:24:33,830 --> 00:24:31,840 the y-jumpers 630 00:24:36,870 --> 00:24:33,840 first retrieve the port jumper and then 631 00:24:38,789 --> 00:24:36,880 he will make his way up to the forward 632 00:24:40,710 --> 00:24:38,799 zenith side of node one into an area we 633 00:24:42,630 --> 00:24:40,720 call the rat's nest because there are so 634 00:24:44,549 --> 00:24:42,640 so many cables inside there he will 635 00:24:46,950 --> 00:24:44,559 demate an existing cable from the rat's 636 00:24:49,029 --> 00:24:46,960 nest and temp stow this y-jumper then he 637 00:24:50,870 --> 00:24:49,039 will translate to node one aft nader 638 00:24:54,710 --> 00:24:50,880 where he will demate another existing 639 00:24:56,310 --> 00:24:54,720 connector and temp stow the y-jumper 640 00:24:59,830 --> 00:24:56,320 at this point time drew will start his 641 00:25:02,070 --> 00:24:59,840 work on the pma-1 fgb interface where he 642 00:25:03,990 --> 00:25:02,080 will demand a connector from the fgb 643 00:25:05,590 --> 00:25:04,000 made it to this new y-jumper and then he 644 00:25:07,430 --> 00:25:05,600 will also demate 645 00:25:09,909 --> 00:25:07,440 a second connector which will route down 646 00:25:12,149 --> 00:25:09,919 to the pdgf once drew is complete with 647 00:25:14,789 --> 00:25:12,159 his work he will give mike a go to start 648 00:25:17,029 --> 00:25:14,799 making his connections mike will make 649 00:25:19,190 --> 00:25:17,039 the rat's nest cable to one end of the y 650 00:25:20,870 --> 00:25:19,200 jumper he will then secure the cable 651 00:25:23,830 --> 00:25:20,880 with wire ties to make sure it doesn't 652 00:25:25,350 --> 00:25:23,840 interfere with translation paths 653 00:25:28,070 --> 00:25:25,360 and then he will translate back down to 654 00:25:32,470 --> 00:25:28,080 node one nader aft again where he will 655 00:25:33,909 --> 00:25:32,480 mate up the second leg of the y-jumper 656 00:25:36,070 --> 00:25:33,919 at this point in time we've completed 657 00:25:37,669 --> 00:25:36,080 work on the port side of the y-jumper 658 00:25:39,190 --> 00:25:37,679 install the ground will start verifying 659 00:25:40,870 --> 00:25:39,200 the connections we made and we'll also 660 00:25:43,029 --> 00:25:40,880 start putting inhibits in place for the 661 00:25:44,950 --> 00:25:43,039 starboard side of these y-jumpers this 662 00:25:46,789 --> 00:25:44,960 task should take about 45 minutes so 663 00:25:50,149 --> 00:25:46,799 during that time we will finish up the 664 00:25:52,710 --> 00:25:50,159 pdgf install by routing the final 1553 665 00:25:54,789 --> 00:25:52,720 data cable this cable routes from 666 00:26:02,950 --> 00:25:54,799 connectors coming off of the pdgf and 667 00:26:05,990 --> 00:26:04,390 once complete with that work and once we 668 00:26:07,750 --> 00:26:06,000 verify that the ground has the inhibits 669 00:26:08,789 --> 00:26:07,760 in place for the starboard y jumper 670 00:26:09,990 --> 00:26:08,799 install 671 00:26:11,669 --> 00:26:10,000 mike will make his way with the 672 00:26:13,430 --> 00:26:11,679 starboard cable back up to the rat's 673 00:26:14,789 --> 00:26:13,440 nest area once again this time on the 674 00:26:16,789 --> 00:26:14,799 starboard side 675 00:26:20,950 --> 00:26:16,799 he will demate an existing rat's nest 676 00:26:24,549 --> 00:26:22,470 then he will translate to node one 677 00:26:29,430 --> 00:26:24,559 afternator where he will demate an 678 00:26:33,110 --> 00:26:30,870 and then drew will start his work once 679 00:26:35,190 --> 00:26:33,120 again on the pma1 fgb interface where he 680 00:26:36,950 --> 00:26:35,200 will demate an fgb cable that he hooks 681 00:26:38,390 --> 00:26:36,960 up to his y-jumper 682 00:26:40,470 --> 00:26:38,400 and then he'll demand a second cable 683 00:26:42,149 --> 00:26:40,480 from the fgb which will route down to 684 00:26:43,669 --> 00:26:42,159 the pdgf 685 00:26:45,190 --> 00:26:43,679 just like on the starboard side once 686 00:26:47,350 --> 00:26:45,200 drew is done with his work he'll give 687 00:26:49,830 --> 00:26:47,360 mike the go mike will start making his 688 00:26:52,390 --> 00:26:49,840 connections he'll first hook up the rats 689 00:26:56,070 --> 00:26:52,400 nest cable to the y jumper 690 00:26:59,750 --> 00:26:57,750 and then make his way 691 00:27:03,510 --> 00:26:59,760 to the node 1 nader aft where he'll 692 00:27:04,950 --> 00:27:03,520 finish up the y jumper install task 693 00:27:07,190 --> 00:27:04,960 once complete both crew members will 694 00:27:09,350 --> 00:27:07,200 translate back over to the pdgf install 695 00:27:11,750 --> 00:27:09,360 site mike will work on cleaning up the 696 00:27:13,669 --> 00:27:11,760 work site and drew will take photos of 697 00:27:15,269 --> 00:27:13,679 the fgb thrusters which are located 698 00:27:17,669 --> 00:27:15,279 right there as well as the newly 699 00:27:19,590 --> 00:27:17,679 installed pdgf both crew members will 700 00:27:25,190 --> 00:27:19,600 then translate back to the airlock and 701 00:27:29,990 --> 00:27:27,830 eva4 is mainly dedicated to stowing 702 00:27:31,909 --> 00:27:30,000 endeavour's orbital boom sensor system 703 00:27:34,389 --> 00:27:31,919 or boom as i'll refer to it on the space 704 00:27:35,990 --> 00:27:34,399 station for a future contingency use in 705 00:27:38,789 --> 00:27:36,000 order to stow this we'll make use of 706 00:27:40,549 --> 00:27:38,799 stands that the sts-123 mission first 707 00:27:43,750 --> 00:27:40,559 used when they stowed the boom in pres 708 00:27:46,389 --> 00:27:43,760 in preparation for sts-124 in order to 709 00:27:48,789 --> 00:27:46,399 get the most use out of this boom as a 710 00:27:50,470 --> 00:27:48,799 contingency tool on station we will need 711 00:27:52,230 --> 00:27:50,480 to change out the grapple fixture which 712 00:27:55,029 --> 00:27:52,240 is located at the end of the boom the 713 00:27:57,029 --> 00:27:55,039 boom currently has an efgf or electrical 714 00:27:58,789 --> 00:27:57,039 flight releasable grapple fixture and 715 00:28:00,870 --> 00:27:58,799 this grapple fixture is not compatible 716 00:28:02,310 --> 00:28:00,880 with the station's robotic arm so we 717 00:28:04,710 --> 00:28:02,320 will work on removing that grapple 718 00:28:07,269 --> 00:28:04,720 fixture and then retrieving a power and 719 00:28:09,110 --> 00:28:07,279 data grapple fixture pdgf from p6 which 720 00:28:11,029 --> 00:28:09,120 is no longer being used and we will 721 00:28:13,190 --> 00:28:11,039 install that on the orbiter boom sensor 722 00:28:16,149 --> 00:28:13,200 system in order to make it more useful 723 00:28:19,110 --> 00:28:16,159 for future station contingencies we'll 724 00:28:21,190 --> 00:28:19,120 finish out the eva on the p3 truss and 725 00:28:23,750 --> 00:28:21,200 the newly installed express logistics 726 00:28:25,830 --> 00:28:23,760 carrier 3 doing some work on dexter's 727 00:28:28,710 --> 00:28:25,840 spare arm which launched on this carrier 728 00:28:30,389 --> 00:28:28,720 when the sts-123 mission first assembled 729 00:28:32,070 --> 00:28:30,399 dexter they had some difficulty 730 00:28:34,230 --> 00:28:32,080 releasing the fasteners that held 731 00:28:36,230 --> 00:28:34,240 dexter's arm and the launch equipment 732 00:28:37,990 --> 00:28:36,240 and so in order to make lives easier for 733 00:28:39,590 --> 00:28:38,000 future station crews and the unlikely 734 00:28:41,510 --> 00:28:39,600 event that they'll need dexter's spare 735 00:28:43,190 --> 00:28:41,520 arm we're going to preemptively release 736 00:28:45,669 --> 00:28:43,200 those fasteners using a specially 737 00:28:47,830 --> 00:28:45,679 designed tool to help lighten the load 738 00:28:48,870 --> 00:28:47,840 on our crew members 739 00:28:52,870 --> 00:28:48,880 with that we can go ahead and roll the 740 00:28:56,710 --> 00:28:54,710 eva 4 will start at the joint airlock 741 00:28:59,110 --> 00:28:56,720 once again with crew members mike fink 742 00:29:00,950 --> 00:28:59,120 and greg chamitov 743 00:29:03,269 --> 00:29:00,960 mike will have a medium bag that 744 00:29:05,110 --> 00:29:03,279 contains the adapter assembly that we 745 00:29:07,269 --> 00:29:05,120 will need to install the pdgf on the 746 00:29:08,950 --> 00:29:07,279 boom he will temporarily stow that on 747 00:29:11,430 --> 00:29:08,960 the s1 truss 748 00:29:12,950 --> 00:29:11,440 and greg will work on reconfiguring and 749 00:29:15,909 --> 00:29:12,960 retrieving a foot restraint which is 750 00:29:17,350 --> 00:29:15,919 currently on the airlock toolbox 751 00:29:19,190 --> 00:29:17,360 he'll stow that on his body restraint 752 00:29:21,190 --> 00:29:19,200 tether and then translate up to the s1 753 00:29:23,029 --> 00:29:21,200 truss 754 00:29:27,750 --> 00:29:23,039 once he's up there he will install that 755 00:29:31,110 --> 00:29:29,430 then he will ingress it ingress the foot 756 00:29:33,110 --> 00:29:31,120 restraint and then both crew members 757 00:29:34,710 --> 00:29:33,120 will work on their own respective stands 758 00:29:36,470 --> 00:29:34,720 and they'll work with box who's inside 759 00:29:38,389 --> 00:29:36,480 the station flying the station's robotic 760 00:29:40,470 --> 00:29:38,399 arm which is grappled to the midpoint of 761 00:29:42,149 --> 00:29:40,480 the boom they'll work together to back 762 00:29:44,389 --> 00:29:42,159 the boom into place to where the eva 763 00:29:46,070 --> 00:29:44,399 crew members can take control of it 764 00:29:47,830 --> 00:29:46,080 box will back off the arm and the two 765 00:29:50,230 --> 00:29:47,840 eva crew members will work together to 766 00:29:52,630 --> 00:29:50,240 slowly back the boom into the stands 767 00:29:55,110 --> 00:29:52,640 they will then lock it in place 768 00:29:57,269 --> 00:29:55,120 mike will start work on the sensor end 769 00:29:59,430 --> 00:29:57,279 of the boom 770 00:30:00,870 --> 00:29:59,440 since without the efgf there's no way to 771 00:30:02,149 --> 00:30:00,880 apply power to these sensors they're 772 00:30:03,990 --> 00:30:02,159 eventually going to die so we will 773 00:30:05,510 --> 00:30:04,000 demate the electrical connectors from 774 00:30:06,950 --> 00:30:05,520 these sensors and install two new 775 00:30:10,789 --> 00:30:06,960 grounding connectors which will ground 776 00:30:14,470 --> 00:30:12,789 while that works ongoing greg is 777 00:30:16,310 --> 00:30:14,480 reconfiguring a foot restraint and 778 00:30:17,909 --> 00:30:16,320 working with box to maneuver the arm 779 00:30:26,789 --> 00:30:17,919 back so greg can install that foot 780 00:30:29,750 --> 00:30:28,310 greg will be using the arm as a work 781 00:30:38,149 --> 00:30:29,760 platform later in the eva for the 782 00:30:42,310 --> 00:30:39,590 both crew members will then translate 783 00:30:43,830 --> 00:30:42,320 all the way out board to the p6 truss 784 00:30:45,990 --> 00:30:43,840 greg will work on setting up the foot 785 00:30:47,510 --> 00:30:46,000 restraint for mike to ingress mike will 786 00:30:49,590 --> 00:30:47,520 hop in the foot restraint install a 787 00:30:51,029 --> 00:30:49,600 handling aid on the pdgf and then 788 00:30:52,950 --> 00:30:51,039 together they will release the four 789 00:30:54,389 --> 00:30:52,960 fasteners that are holding the pdgf on 790 00:30:56,149 --> 00:30:54,399 the p6 truss 791 00:31:00,070 --> 00:30:56,159 once released they will stow the grapple 792 00:31:01,669 --> 00:31:00,080 fixture on mike's body restraint tether 793 00:31:02,710 --> 00:31:01,679 and greg will retrieve the foot 794 00:31:04,149 --> 00:31:02,720 restraint 795 00:31:05,990 --> 00:31:04,159 both crew members will then start making 796 00:31:08,310 --> 00:31:06,000 their way back towards the s1 truss and 797 00:31:09,509 --> 00:31:08,320 the boom greg will make a quick pit stop 798 00:31:14,630 --> 00:31:09,519 where he will drop off that foot 799 00:31:18,310 --> 00:31:16,549 and then greg will work with box to 800 00:31:19,669 --> 00:31:18,320 slowly maneuver the arm into position to 801 00:31:25,190 --> 00:31:19,679 where greg can ingress the foot 802 00:31:28,789 --> 00:31:26,789 greg will then maneuver over to mike 803 00:31:30,549 --> 00:31:28,799 where he will retrieve the pdgf and stow 804 00:31:32,310 --> 00:31:30,559 that on his body restraint tether and 805 00:31:35,430 --> 00:31:32,320 then both crew members will translate up 806 00:31:37,430 --> 00:31:35,440 to the grapple fixture swap location 807 00:31:39,669 --> 00:31:37,440 they will work on releasing the efgf 808 00:31:41,029 --> 00:31:39,679 which has six bolts once they release 809 00:31:43,190 --> 00:31:41,039 that they will need to peel back the 810 00:31:45,509 --> 00:31:43,200 efgf and cut the electrical cable that 811 00:31:47,029 --> 00:31:45,519 runs down to those sensors mike will 812 00:31:49,190 --> 00:31:47,039 stow that in the medium bag then they 813 00:31:50,870 --> 00:31:49,200 will work on installing the pdgf adapter 814 00:31:52,630 --> 00:31:50,880 assembly or paa 815 00:31:54,549 --> 00:31:52,640 this has six bolts and then it provides 816 00:31:58,310 --> 00:31:54,559 a mounting ring for the pdgf to be 817 00:32:01,430 --> 00:31:59,830 they'll then work together to install 818 00:32:04,070 --> 00:32:01,440 the pdgf and tighten down the four 819 00:32:05,669 --> 00:32:04,080 fasteners that hold it in place 820 00:32:07,909 --> 00:32:05,679 and we now have a new grapple fixture on 821 00:32:09,509 --> 00:32:07,919 the end of the boom 822 00:32:11,430 --> 00:32:09,519 greg will then work with box to maneuver 823 00:32:13,269 --> 00:32:11,440 back to his egress position where he 824 00:32:15,029 --> 00:32:13,279 will egress the apfr and then catch a 825 00:32:17,509 --> 00:32:15,039 free ride over to the starboard seat of 826 00:32:20,549 --> 00:32:19,110 greg we'll transfer the foot restraint 827 00:32:31,990 --> 00:32:20,559 from the arm 828 00:32:36,389 --> 00:32:34,070 greg then translates to the zenith f 829 00:32:38,310 --> 00:32:36,399 side of s zero where he inspects and 830 00:32:40,549 --> 00:32:38,320 cinches a long duration title tether 831 00:32:45,509 --> 00:32:40,559 which is currently holding down dexter's 832 00:32:49,350 --> 00:32:47,269 meanwhile mike has retrieved that medium 833 00:32:51,029 --> 00:32:49,360 bag that contained the efgf which was 834 00:32:53,110 --> 00:32:51,039 removed from the boom and he translates 835 00:32:54,789 --> 00:32:53,120 down to endeavour's payload bay once 836 00:32:56,870 --> 00:32:54,799 he's down there he opens up the door on 837 00:32:59,750 --> 00:32:56,880 endeavour's port toolbox or tool stowage 838 00:33:01,990 --> 00:32:59,760 assembly and he will transfer the efgf 839 00:33:04,230 --> 00:33:02,000 grapple fixture from his medium bag to 840 00:33:07,350 --> 00:33:04,240 this port tsa so it can return home with 841 00:33:11,669 --> 00:33:09,590 once he's complete stowing that grapple 842 00:33:12,470 --> 00:33:11,679 fixture in the tsa he will close the 843 00:33:14,870 --> 00:33:12,480 door 844 00:33:16,230 --> 00:33:14,880 and tighten the four latches 845 00:33:18,870 --> 00:33:16,240 and then both crew members will start 846 00:33:21,029 --> 00:33:18,880 making their way out to the port truss 847 00:33:23,029 --> 00:33:21,039 once out on p3 848 00:33:24,710 --> 00:33:23,039 they will translate along the newly 849 00:33:26,789 --> 00:33:24,720 installed express logistics carrier 850 00:33:28,789 --> 00:33:26,799 elc-3 and this is where they will work 851 00:33:30,950 --> 00:33:28,799 on releasing the three fasteners that 852 00:33:33,590 --> 00:33:30,960 held dexter's spare arm in place for 853 00:33:37,669 --> 00:33:35,669 once the first fastener is is released 854 00:33:39,430 --> 00:33:37,679 they will work together to use a 40 inch 855 00:33:41,190 --> 00:33:39,440 long pry rod this was the tool that was 856 00:33:42,950 --> 00:33:41,200 specially designed for this task one 857 00:33:44,870 --> 00:33:42,960 crew member will insert this pry load 858 00:33:46,470 --> 00:33:44,880 and offload the adjacent fasteners as 859 00:33:47,590 --> 00:33:46,480 the other crew member releases those 860 00:33:50,630 --> 00:33:47,600 fasteners 861 00:33:57,430 --> 00:33:50,640 are two clamps that are still holding 862 00:34:01,110 --> 00:33:59,110 once complete with that task greg will 863 00:34:02,789 --> 00:34:01,120 translate to the opposite side of elc 3 864 00:34:04,070 --> 00:34:02,799 where he will install a protective cover 865 00:34:06,310 --> 00:34:04,080 on the grapple fixture on the high 866 00:34:07,990 --> 00:34:06,320 pressure gas tank he will also take some 867 00:34:13,270 --> 00:34:08,000 photos of a dod 868 00:34:16,710 --> 00:34:14,950 both crew members will clean up their 869 00:34:19,109 --> 00:34:16,720 work site and translate back to the 870 00:34:21,510 --> 00:34:19,119 joint airlock they will ingress 871 00:34:22,950 --> 00:34:21,520 and we will be closing the hatch for the 872 00:34:24,950 --> 00:34:22,960 final time 873 00:34:32,149 --> 00:34:24,960 on an eva conducted by space shuttle 874 00:34:35,510 --> 00:34:33,510 so with that that completes my briefing 875 00:34:37,270 --> 00:34:35,520 i'll hand it back over to you okay let's 876 00:34:38,869 --> 00:34:37,280 take some questions here at the johnson 877 00:34:40,710 --> 00:34:38,879 space center first and we'll see if we 878 00:34:42,950 --> 00:34:40,720 have any of the other centers 879 00:34:44,790 --> 00:34:42,960 who would like to go first go ahead 880 00:34:47,909 --> 00:34:44,800 mark kramer from cbs 881 00:34:50,149 --> 00:34:47,919 the pdgf that comes off p6 was that a 882 00:34:51,829 --> 00:34:50,159 spare or was that used actively and 883 00:34:54,310 --> 00:34:51,839 taking it away does that mean you lose 884 00:34:55,990 --> 00:34:54,320 some capability it was used so that pdgf 885 00:34:57,750 --> 00:34:56,000 doesn't have any power or anything 886 00:35:00,150 --> 00:34:57,760 provided to it so it was never used as a 887 00:35:03,030 --> 00:35:00,160 base for the ssrms it was used when they 888 00:35:04,630 --> 00:35:03,040 first installed p6 on top of z1 during 889 00:35:06,630 --> 00:35:04,640 the foray mission 890 00:35:09,430 --> 00:35:06,640 so it's just it's just out there now not 891 00:35:16,710 --> 00:35:11,670 anyone else 892 00:35:20,950 --> 00:35:18,790 marcia done associated press 893 00:35:23,109 --> 00:35:20,960 um because you had that one extra day 894 00:35:25,270 --> 00:35:23,119 maybe um if you didn't get everything 895 00:35:27,589 --> 00:35:25,280 done during four would you consider a 50 896 00:35:28,870 --> 00:35:27,599 va or are you pretty hard down with four 897 00:35:30,150 --> 00:35:28,880 this time 898 00:35:32,310 --> 00:35:30,160 i think i think we'll be pretty good 899 00:35:34,069 --> 00:35:32,320 with with four evas i don't think it 900 00:35:36,390 --> 00:35:34,079 with that plus one day since we only 901 00:35:38,470 --> 00:35:36,400 have three total crew members we can't 902 00:35:40,069 --> 00:35:38,480 do back-to-back evas so we would need to 903 00:35:42,310 --> 00:35:40,079 add two additional days in order to 904 00:35:44,230 --> 00:35:42,320 support a fifth eva but i think we 905 00:35:46,069 --> 00:35:44,240 should have enough time and this crew is 906 00:35:47,589 --> 00:35:46,079 so well trained that i don't think we 907 00:35:49,109 --> 00:35:47,599 should we should easily be able to fit 908 00:35:51,829 --> 00:35:49,119 all of our nominal tasks within our four 909 00:35:56,790 --> 00:35:53,990 okay claire 910 00:35:58,790 --> 00:35:56,800 hi clara moskowitz with space.com um can 911 00:36:01,270 --> 00:35:58,800 you just talk about in general how these 912 00:36:04,230 --> 00:36:01,280 evas rate in terms of difficulty and 913 00:36:05,829 --> 00:36:04,240 complexity to general evas and also just 914 00:36:07,510 --> 00:36:05,839 how much time the crews have had to put 915 00:36:09,829 --> 00:36:07,520 in to rehearse these 916 00:36:11,510 --> 00:36:09,839 okay great question so let's see i'll 917 00:36:13,030 --> 00:36:11,520 fir i'll answer your second question 918 00:36:14,950 --> 00:36:13,040 first so 919 00:36:16,150 --> 00:36:14,960 in terms of the number of runs that 920 00:36:17,589 --> 00:36:16,160 we've done in the neutral buoyancy lab 921 00:36:19,109 --> 00:36:17,599 for each of the evas it's helped that 922 00:36:20,790 --> 00:36:19,119 we've slipped about nine months since 923 00:36:23,910 --> 00:36:20,800 our original launch date in july so for 924 00:36:25,589 --> 00:36:23,920 eva's one and two we've done 10 runs eva 925 00:36:27,430 --> 00:36:25,599 3 since that was added later in the flow 926 00:36:30,069 --> 00:36:27,440 we've done four runs of that and then 927 00:36:31,910 --> 00:36:30,079 we've done nine runs of eva four 928 00:36:33,510 --> 00:36:31,920 so that's ten ten 929 00:36:36,150 --> 00:36:33,520 four and nine 930 00:36:38,390 --> 00:36:36,160 so in terms of difficulty i would say i 931 00:36:41,190 --> 00:36:38,400 think evas one three and four are 932 00:36:43,190 --> 00:36:41,200 probably standard difficulty level evas 933 00:36:45,270 --> 00:36:43,200 eva2 is the one that 934 00:36:47,430 --> 00:36:45,280 involves quite a bit of choreography 935 00:36:50,630 --> 00:36:47,440 between the ground for both the the 936 00:36:52,069 --> 00:36:50,640 refill of the of the p6 cooling system 937 00:36:53,430 --> 00:36:52,079 the crew members have to wait for goes 938 00:36:55,030 --> 00:36:53,440 from the ground and then have to give 939 00:36:57,030 --> 00:36:55,040 the ground goes and so there's quite a 940 00:36:58,870 --> 00:36:57,040 bit of choreography between 941 00:37:00,710 --> 00:36:58,880 between that fill task and also just the 942 00:37:02,470 --> 00:37:00,720 sheer number of fluid quick disconnects 943 00:37:04,390 --> 00:37:02,480 that we're touching during this eva 944 00:37:06,710 --> 00:37:04,400 those fluid qd's have historically 945 00:37:09,109 --> 00:37:06,720 caused quite a few problems during evas 946 00:37:10,950 --> 00:37:09,119 so we have i think it's a total of 11 947 00:37:12,630 --> 00:37:10,960 fluid fluid cuties that we're touching 948 00:37:14,470 --> 00:37:12,640 throughout this eva multiple times we're 949 00:37:16,310 --> 00:37:14,480 opening and closing them both a few 950 00:37:17,589 --> 00:37:16,320 times on eva one but most of the time on 951 00:37:18,870 --> 00:37:17,599 eva ii 952 00:37:20,630 --> 00:37:18,880 so that's probably one of the most 953 00:37:22,150 --> 00:37:20,640 difficult and challenging tasks on this 954 00:37:23,430 --> 00:37:22,160 flight 955 00:37:35,190 --> 00:37:23,440 okay 956 00:37:39,109 --> 00:37:36,950 angie king with harvard journalism can 957 00:37:40,870 --> 00:37:39,119 you explain again what is it about what 958 00:37:45,030 --> 00:37:40,880 you call the slow hokey pokey that 959 00:37:47,109 --> 00:37:45,040 exercise that makes the aisle possible 960 00:37:48,790 --> 00:37:47,119 i'm definitely not a medical doctor and 961 00:37:50,470 --> 00:37:48,800 i did not stay at a holiday inn express 962 00:37:52,470 --> 00:37:50,480 last night so i can't even pretend to be 963 00:37:54,870 --> 00:37:52,480 one but it's my understanding that it's 964 00:37:56,470 --> 00:37:54,880 it's all about the oxygen exchange so 965 00:37:58,710 --> 00:37:56,480 just the fact that you're in the suit 966 00:38:00,150 --> 00:37:58,720 and you're exerting you know you're 967 00:38:01,349 --> 00:38:00,160 exerting yourself a little bit and 968 00:38:02,790 --> 00:38:01,359 you're kind of getting your heart rate 969 00:38:04,630 --> 00:38:02,800 up so your blood's pumping a little bit 970 00:38:06,470 --> 00:38:04,640 faster and it's so it's all about 971 00:38:08,310 --> 00:38:06,480 exertion level and so you're exchanging 972 00:38:10,230 --> 00:38:08,320 oxygen at a higher rate and then the 973 00:38:11,750 --> 00:38:10,240 actual movement itself helps move any 974 00:38:13,829 --> 00:38:11,760 little nitrogen bubbles that might be in 975 00:38:15,109 --> 00:38:13,839 the veins so it's all about 976 00:38:17,030 --> 00:38:15,119 just kind of working yourself out a 977 00:38:19,349 --> 00:38:17,040 little bit and like you saw it's very 978 00:38:20,470 --> 00:38:19,359 very light exercise that we're talking 979 00:38:21,750 --> 00:38:20,480 about here because we don't want the 980 00:38:23,670 --> 00:38:21,760 crew members to wear themselves out 981 00:38:26,230 --> 00:38:23,680 before they go out the door but just 982 00:38:30,069 --> 00:38:26,240 anything over just sitting there helps 983 00:38:33,990 --> 00:38:30,950 okay 984 00:38:37,829 --> 00:38:35,910 marshad and associated press again this 985 00:38:39,670 --> 00:38:37,839 will be the last shuttle crew going out 986 00:38:42,710 --> 00:38:39,680 on a spacewalk ever 987 00:38:44,470 --> 00:38:42,720 um have you given that much thought or 988 00:38:45,349 --> 00:38:44,480 what what are your thoughts about 989 00:38:46,790 --> 00:38:45,359 you know 990 00:38:48,790 --> 00:38:46,800 30 years of 991 00:38:50,150 --> 00:38:48,800 you know shuttle program ending in the 992 00:38:53,829 --> 00:38:50,160 last the very last shuttle-based 993 00:38:55,910 --> 00:38:53,839 spacewalk right well you know i grew up 994 00:38:58,710 --> 00:38:55,920 i hate to admit it but i was born after 995 00:39:00,950 --> 00:38:58,720 sts-1 so i have only ever known a world 996 00:39:02,710 --> 00:39:00,960 that's had shuttle flights in it so it's 997 00:39:04,710 --> 00:39:02,720 it's going to be a very a very 998 00:39:06,950 --> 00:39:04,720 bittersweet but very proud moment for me 999 00:39:08,470 --> 00:39:06,960 to be able to help execute 1000 00:39:10,470 --> 00:39:08,480 these evas 1001 00:39:11,670 --> 00:39:10,480 and you know i think life aboard the 1002 00:39:13,349 --> 00:39:11,680 space station is still going to be 1003 00:39:15,109 --> 00:39:13,359 exciting in terms of evas we're still 1004 00:39:16,870 --> 00:39:15,119 going to be doing spacewalk so my job 1005 00:39:19,190 --> 00:39:16,880 personally won't won't change that much 1006 00:39:20,390 --> 00:39:19,200 but we'll continue to do spacewalks 1007 00:39:22,630 --> 00:39:20,400 but i think it'll just be a very 1008 00:39:23,990 --> 00:39:22,640 exciting time to actually complete to 1009
