the boom clear of the pallet 121 00:04:32,710 --> 00:04:30,800 once he's clear of the pallet he's going 122 00:04:35,590 --> 00:04:32,720 to go ahead and reposition the boom for 123 00:04:37,430 --> 00:04:35,600 installation at the z1 work site 124 00:04:39,350 --> 00:04:37,440 steve will then pick up his 125 00:04:41,350 --> 00:04:39,360 foot restraint 126 00:04:43,510 --> 00:04:41,360 translate back over to the 127 00:04:46,150 --> 00:04:43,520 port cedar cart which will drop it off 128 00:04:47,510 --> 00:04:46,160 we'll use that later when we install the 129 00:04:49,670 --> 00:04:47,520 pallet onto the 130 00:04:51,270 --> 00:04:49,680 dexter 131 00:04:52,870 --> 00:04:51,280 and then as we fly over here you can see 132 00:04:53,909 --> 00:04:52,880 that one big dish antenna is the 133 00:04:55,670 --> 00:04:53,919 existing 134 00:04:57,030 --> 00:04:55,680 space to ground antenna on the station 135 00:04:58,950 --> 00:04:57,040 and we are going to install the 136 00:05:00,870 --> 00:04:58,960 redundant system 137 00:05:02,629 --> 00:05:00,880 just starboard of it 138 00:05:04,070 --> 00:05:02,639 whereas that first antenna slopes off to 139 00:05:06,629 --> 00:05:04,080 the side ours 140 00:05:08,390 --> 00:05:06,639 will become a new 14 foot tall straight 141 00:05:09,590 --> 00:05:08,400 up structure right 142 00:05:12,390 --> 00:05:09,600 next to it in the center of the space 143 00:05:15,510 --> 00:05:13,830 so garrett you'll see here is about to 144 00:05:19,350 --> 00:05:15,520 do these big uh we'll call windshield 145 00:05:20,469 --> 00:05:19,360 wiper maneuvers over to the z1 146 00:05:22,870 --> 00:05:20,479 once 147 00:05:24,310 --> 00:05:22,880 he's over at the work site 148 00:05:26,150 --> 00:05:24,320 steve will have translated over there 149 00:05:28,550 --> 00:05:26,160 they'll work together 150 00:05:31,350 --> 00:05:28,560 to position the boom you can see here 151 00:05:33,749 --> 00:05:31,360 working in the neutral buoyancy lab 152 00:05:35,430 --> 00:05:33,759 to practice that steve will go ahead and 153 00:05:38,230 --> 00:05:35,440 drive the bolts there's two bolts that 154 00:05:40,870 --> 00:05:38,240 hold the boom onto the z1 and then 155 00:05:42,469 --> 00:05:40,880 garrett will go ahead and fly back 156 00:05:44,070 --> 00:05:42,479 to pick up the dish 157 00:05:45,189 --> 00:05:44,080 while he's gone steve is going to 158 00:05:47,670 --> 00:05:45,199 connect a couple of electrical 159 00:05:50,070 --> 00:05:47,680 connectors to an interface panel 160 00:05:51,670 --> 00:05:50,080 he'll then grab four other electrical 161 00:05:52,629 --> 00:05:51,680 connectors that were pre-positioned for 162 00:05:56,070 --> 00:05:52,639 us 163 00:05:58,070 --> 00:05:56,080 to the boom 164 00:06:00,550 --> 00:05:58,080 and once that is complete if he still 165 00:06:02,550 --> 00:06:00,560 has time he'll translate up the boom 166 00:06:04,390 --> 00:06:02,560 and remove the thermal cover from the 167 00:06:16,629 --> 00:06:04,400 transmit receive box 168 00:06:23,510 --> 00:06:18,870 okay in the meantime we have garrett as 169 00:06:27,590 --> 00:06:25,590 he'll work with piers 170 00:06:29,430

--> 00:06:35,039 he'll drive each of those bolts and then 174 00:06:38,790 --> 00:06:36,720 very carefully 175 00:06:41,990 --> 00:06:38,800 start to lift the dish 176 00:06:43,189 --> 00:06:42,000 out of that support equipment 177 00:06:46,070 --> 00:06:43,199 a little bit of a 178 00:06:49,029 --> 00:06:46,080 tight space here so 179 00:06:50,309 --> 00:06:49,039 they'll work together just get clear of 180 00:06:51,670 --> 00:06:50,319 the pallet 181 00:06:52,790 --> 00:06:51,680 then do a little maneuver out from 182 00:06:54,870 --> 00:06:52,800 underneath the 183 00:06:56,550 --> 00:06:54,880 boom of the arm and then again the big 184 00:06:59,029 --> 00:06:56,560 windshield wiper maneuver 185 00:07:00,710 --> 00:06:59,039 back over to the z1 186 00:07:02,070 --> 00:07:00,720 when garrett arrives at the z1 steve 187 00:07:03,670 --> 00:07:02,080 should be waiting for him at the top of 188 00:07:06,309 --> 00:07:03,680 the boom 189 00:07:08,710 --> 00:07:06,319 they're going to again work together to 190 00:07:11,110 --> 00:07:08,720 very gently bring those two interfaces 191 00:07:12,950 --> 00:07:11,120 together there's some very sensitive 192 00:07:15,029 --> 00:07:12,960 areas up the top there where the actual 193 00:07:16,390 --> 00:07:15,039 signal passes through from the antenna 194 00:07:17,909 --> 00:07:16,400 down into the 195 00:07:19,430 --> 00:07:17,919 boom box 196 00:07:20,390 --> 00:07:19,440 that we call it 197 00:07:22,710 --> 00:07:20,400 and 198 00:07:27,510 --> 00:07:22,720 locate go ahead work together drive four 199 00:07:31,029 --> 00:07:28,550 once the 200 00:07:32,230 --> 00:07:31,039 dish is bolted on there's two electrical 201 00:07:34,550 --> 00:07:32,240 connectors 202 00:07:36,710 --> 00:07:34,560 that need to get 203 00:07:38,150 --> 00:07:36,720 connected 204 00:07:40,550 --> 00:07:38,160 and then 205 00:07:42,070 --> 00:07:40,560 just before garrett leaves they'll go 206 00:07:43,670 --> 00:07:42,080 ahead and work together to install a 207 00:07:48,629 --> 00:07:43,680 thermal shield 208 00:07:51,909 --> 00:07:50,070 you can see that's what white section 209 00:07:54,469 --> 00:07:51,919 that just went on there as soon as that 210 00:07:55,589 --> 00:07:54,479 is complete we'll send garrett back over 211 00:07:57,589 --> 00:07:55,599 to the pallet 212 00:07:58,710 --> 00:07:57,599 to start the retrieval of the dexter 213 00:08:00,469 --> 00:07:58,720 platform 214 00:08:02,550 --> 00:08:00,479 steve will then 215 00:08:04,230 --> 00:08:02,560 proceed to remove two launch locks 216 00:08:05,990 --> 00:08:04,240 gimbal locks we call them 217 00:08:07,830 --> 00:08:06,000 on the antenna those immobilize the 218 00:08:11,430 --> 00:08:07,840 antenna during its 219 00:08:14,629 --> 00:08:12,710 and once he is finished with those 220 00:08:16,710 --> 00:08:14,639 gimbal locks he'll go ahead 221 00:08:18,390 --> 00:08:16,720 clean up that z1 work site 222 00:08:19,909 --> 00:08:18,400 drop a bag off at the airlock and then 223 00:08:21,189 --> 00:08:19,919 meet garrett 224 00:08:23,830 --> 00:08:21,199 back over at the dexter for the 225 00:08:25,670 --> 00:08:23,840 installation of the platform 226 00:08:27,830 --> 00:08:25,680 here you can see garrett once he gets 227 00:08:29,430 --> 00:08:27,840 back over to the pallet 228 00:08:33,430 --> 00:08:29,440 he's driving 229 00:08:38,310 --> 00:08:33,440 one of the four bolts here that hold the 230 00:08:44,230 --> 00:08:41,269 and once that platform is released 231 00:08:45,670 --> 00:08:44,240 he'll again go ahead and 232 00:08:47,590 --> 00:08:45,680 pull that away from the pallet and then 233 00:08:49,509 --> 00:08:47,600 again another big sweeping maneuver just 234 00:08:50,949 --> 00:08:49,519 from one side of the mobile transporter 235 00:08:52,550 --> 00:08:50,959 over to the other side 236 00:08:54,070 --> 00:08:52,560 this is kind of like going around the 237 00:08:57,350 --> 00:08:54,080 block to get your next door neighbor's 238 00:09:00,710 --> 00:08:59,350 so then once garrett's over there with 239 00:09:02,630 --> 00:09:00,720 the pallet 240 00:09:04,870 --> 00:09:02,640 he and steve will work together 241 00:09:07,430 --> 00:09:04,880 to insert four fasteners 242 00:09:09,910 --> 00:09:07,440 that hold the pallet onto the dexter 243 00:09:13,350 --> 00:09:09,920 there's also a hinge pin this platform 244 00:09:18,550 --> 00:09:15,350 during future operations for 245 00:09:21,030 --> 00:09:18,560 into what we call a maintenance position 246 00:09:23,430 --> 00:09:21,040 once garrett and steve are complete with 247 00:09:25,030 --> 00:09:23,440 the fasteners garrett will egress the 248 00:09:27,030 --> 00:09:25,040 arm and then send that away to a 249 00:09:29,670 --> 00:09:27,040 position that he can later take the foot 250 00:09:31,190 --> 00:09:29,680 restraint off of it and clean it up 251 00:09:33,990 --> 00:09:31,200 and if we have time at this point 252 00:09:34,710 --> 00:09:34,000 garrett's going to head and install 253 00:10:08,630 --> 00:09:34,720 a 254 00:10:10,470 --> 00:10:08,640 is either for the dexter itself or for 255 00:10:11,590 --> 00:10:10,480 an ev crew to actually rotate that 256 00:10:13,509 --> 00:10:11,600 pallet 257 00:10:15,509 --> 00:10:13,519 180 degrees in either direction 258 00:10:16,870 --> 00:10:15,519 depending on well 259 00:10:19,910 --> 00:10:16,880 what piece of equipment you would like 260 00:10:22,470 --> 00:10:19,920 to temporarily stow there 261 00:10:24,470 --> 00:10:22,480 while all that is taking place 262 00:10:26,150 --> 00:10:24,480 steve will have translated back over to 263 00:10:27,590 --> 00:10:26,160 the pallet to perform some get-ahead 264 00:10:29,990 --> 00:10:27,600 tasks for us 265 00:10:32,790 --> 00:10:30,000 we're going to have him break torque 266 00:10:35,110 --> 00:10:32,800 on the batteries that are on the pallet 267 00:10:35,829 --> 00:10:35,120 so for each of the six batteries he'll 268 00:10:37,269 --> 00:10:35,839 be 269 00:10:38,949 --> 00:10:37,279 opening up the 270 00:10:42,150 --> 00:10:38,959 thermal cover 271 00:10:44,150 --> 00:10:42,160 and then using a ratchet wrench 272 00:10:46,389 --> 00:10:44,160 to release the torque just by putting 273 00:10:48,069 --> 00:10:46,399 one turn on each of those bolts and then 274 00:10:50,069 --> 00:10:48,079 he'll 275 00:10:53,590 --> 00:10:50,079 torque it back down by hand and that's 276 00:10:55,670 --> 00:10:53,600 so that we can easily use our power tool 277 00:10:57,350 --> 00:10:55,680 during evas two and three to remove the 278 00:10:59,110 --> 00:10:57,360 batteries 279 00:11:02,790 --> 00:10:59,120 from the pallet and you can see here 280 00:11:04,790 --> 00:11:02,800 steve practicing that again in the pool 281 00:11:06,150 --> 00:11:04,800 once he's broken torque on 282 00:11:07,990 --> 00:11:06,160 as many of the batteries we can get 283 00:11:10,160 --> 00:11:08,000 through we'd like to get through all six 284 00:11:11,269 --> 00:11:10,170 but it's not required he'll go ahead and 285 00:11:12,710 --> 00:11:11,279 [Music] 286 00:11:15,110 --> 00:11:12,720 close the thermal 287 00:11:17,670 --> 00:11:15,120 cover back up 288 00:11:20,470 --> 00:11:17,680 and that will be the completion of eva 289 00:11:32,710 --> 00:11:20,480 one we'll bring our bags back inside and 290 00:11:35,670 --> 00:11:34,230 okay 291 00:11:39,110 --> 00:11:35,680 for eva 292 00:11:40,630 --> 00:11:39,120 two we'll have steve bowen and mike good 293 00:11:43,670 --> 00:11:40,640 going out the door 294 00:11:46,230 --> 00:11:43,680 steve will take the lead on this eva 295 00:11:48,230 --> 00:11:46,240 prior to egress on this eva the mobile 296 00:11:50,310 --> 00:11:48,240 transporter will move down to its port 297 00:11:52,069 --> 00:11:50,320 most location 298 00:11:54,870 --> 00:11:52,079 on the trust just prior to the solar 299 00:11:57,350 --> 00:11:54,880 array rotary joint 300 00:11:59,509 --> 00:11:57,360 garrett in piers will then work together 301 00:12:00,870 --> 00:11:59,519 to pull the pallet 302 00:12:02,550 --> 00:12:00,880 off of the 303 00:12:04,870 --> 00:12:02,560 mobile transporter 304 00:12:06,310 --> 00:12:04,880 and extend it all the way out to the p6 305 00:12:08,310 --> 00:12:06,320 segment 306 00:12:14,870 --> 00:12:08,320 for the start of the eva 307 00:12:19,110 --> 00:12:16,710 so here you see we're coming into our 308 00:12:20,310 --> 00:12:19,120 work site at the far port end of the 309 00:12:22,550 --> 00:12:20,320 truss 310 00:12:25,030 --> 00:12:22,560 our first task on this eva is going to 311 00:12:27,269 --> 00:12:25,040 be to move a couple of portable foot 312 00:12:29,750 --> 00:12:27,279 restraints and some gap spanner chains 313 00:12:32,310 --> 00:12:29,760 that have been out there since sts-127 314 00:12:34,389 --> 00:12:32,320 back last july 315 00:12:36,310 --> 00:12:34,399 when they did the very similar task of 316 00:12:39,750 --> 00:12:36,320 rnr 317 00:12:41,590 --> 00:12:39,760 those batteries so steve bowen will grab 318 00:12:43,990 --> 00:12:41,600 each of those foot restraints 319 00:12:45,110 --> 00:12:44,000 bring them over to the opposite side of 320 00:12:47,509 --> 00:12:45,120 the truss 321 00:12:49,750 --> 00:12:47,519 where we'll be doing our battery 322 00:12:50,870 --> 00:12:49,760 remove and replace 323 00:12:52,470 --> 00:12:50,880 and 324 00:12:53,990 --> 00:12:52,480 grab those foot restraints grab that gap 325 00:12:55,110 --> 00:12:54,000 spanner chain install it on the other 326 00:12:57,509 --> 00:12:55,120 side 327 00:13:00,629 --> 00:12:57,519 and while steve is doing that 328 00:13:03,750 --> 00:13:00,639 mike will go around and break torque 329 00:13:05,110 --> 00:13:03,760 on each of the six truss batteries again 330 00:13:07,430 --> 00:13:05,120 with a ratchet wrench similar to what 331 00:13:12,310 --> 00:13:07,440 steve did on the pallet for 332 00:13:15,750 --> 00:13:13,670 once they're complete with all those 333 00:13:17,190 --> 00:13:15,760 prep activities 334 00:13:20,150 --> 00:13:17,200 the first thing we need to do this whole 335 00:13:21,590 --> 00:13:20,160 battery rnr is like a shell game or one 336 00:13:22,949 --> 00:13:21,600 of those puzzles where you move the 337 00:13:25,269 --> 00:13:22,959 numbers around the first thing you need 338 00:13:27,670 --> 00:13:25,279 to do is create an open spot 339 00:13:30,470 --> 00:13:27,680 to start your shuffle so we'll install 340 00:13:32,870 --> 00:13:30,480 some handling aids onto the battery 341 00:13:36,150 --> 00:13:32,880 first a battery that we intend to remove 342 00:13:38,710 --> 00:13:36,160 and then we're also going to install a 343 00:13:40,710 --> 00:13:38,720 we call a ball stack it's a tether metal 344 00:13:44,310 --> 00:13:40,720 tether that can be rigidized to 345 00:13:48,629 --> 00:13:46,790 during the evas 346 00:13:52,470 --> 00:13:48,639 so there you see 347 00:13:59,590 --> 00:13:52,480 mike putting that ball stack in place 348 00:14:05,590 --> 00:14:03,350 mike will go ahead and ingress the 349 00:14:07,269 --> 00:14:05,600 foot restraint we call we call mike the 350 00:14:09,750 --> 00:14:07,279 trust guy and steve will be the pallet 351 00:14:11,110 --> 00:14:09,760 guy because mike takes all the batteries 352 00:14:12,870 --> 00:14:11,120 out of the truss and replaces them and 353 00:14:15,030 --> 00:14:12,880 steve will take the batteries out of the 354 00:14:16,389 --> 00:14:15,040 pallet and replace them 355 00:14:17,350 --> 00:14:16,399 so here you can see they're working 356 00:14:18,629 --> 00:14:17,360 together 357 00:14:19,829 --> 00:14:18,639 mike's pulled the battery out of the 358 00:14:21,750 --> 00:14:19,839 truss 359 00:14:24,470 --> 00:14:21,760 and then they pass it down to the 360 00:14:27,110 --> 00:14:24,480 tempstow location 361 00:14:28,710 --> 00:14:27,120 we'll install it onto that ball stack 362 00:14:30,470 --> 00:14:28,720 and then 363 00:14:31,829 --> 00:14:30,480 tuck it under the truss there to keep it 364 00:14:33,670 --> 00:14:31,839 out of the way during the robotics 365 00:14:35,430 --> 00:14:33,680 operations 366 00:14:37,269 --> 00:14:35,440 and then mike will reposition his foot 367 00:14:39,110 --> 00:14:37,279 restraint for the installation of the 368 00:14:40,550 --> 00:14:39,120 battery 369 00:14:43,590 --> 00:14:40,560 at this point 370 00:14:44,710 --> 00:14:43,600 steve will guide the pallet that appears 371 00:14:46,310 --> 00:14:44,720 as 372 00:14:47,910 --> 00:14:46,320 operating the arm there 373 00:14:49,990 --> 00:14:47,920 guide the pallet in for the removal of 374 00:14:51,590 --> 00:14:50,000 the first battery 375 00:14:53,189 --> 00:14:51,600 you know better and the pallet gets 376 00:14:54,550 --> 00:14:53,199 close enough it'll go ahead and open the 377 00:14:58,150 --> 00:14:54,560 thermal clever 378 00:14:59,750 --> 00:14:58,160 install a couple more handling aids pull 379 00:15:01,670 --> 00:14:59,760 that battery out 380 00:15:04,230 --> 00:15:01,680 here you can see them practicing 381 00:15:05,430 --> 00:15:04,240 that again in the pool 382 00:15:06,870 --> 00:15:05,440 training for this was challenging 383 00:15:08,150 --> 00:15:06,880 because since we couldn't put the pallet 384 00:15:10,790 --> 00:15:08,160 on the arm in the pool we had to 385 00:15:15,030 --> 00:15:10,800 actually put the crew member on the arm 386 00:15:17,670 --> 00:15:16,629 so there's steve pulling the battery out 387 00:15:19,910 --> 00:15:17,680 of the 388 00:15:21,670 --> 00:15:19,920 pallet as he'll do on 389 00:15:24,230 --> 00:15:21,680 eva2 390 00:15:25,590 --> 00:15:24,240 once the battery has been removed 391 00:15:27,189 --> 00:15:25,600 they'll work together to what we call 392 00:15:29,509 --> 00:15:27,199 shepherd the battery down to its install 393 00:15:30,870 --> 00:15:29,519 location that's just basically a hand 394 00:15:32,470 --> 00:15:30,880 handoff 395 00:15:35,269 --> 00:15:32,480 from one crew member to the next kind of 396 00:15:37,110 --> 00:15:35,279 inchworm it down the truss 397 00:15:40,230 --> 00:15:37,120 and then 398 00:15:41,829 --> 00:15:40,240 install it back into the truss these 399 00:15:44,150 --> 00:15:41,839 batteries are about three and a half 400 00:15:47,189 --> 00:15:44,160 feet by three and a half feet each 401 00:15:49,430 --> 00:15:47,199 uh weigh about 365 pounds 402 00:15:51,910 --> 00:15:49,440 so you can imagine uh there when steve 403 00:15:53,430 --> 00:15:51,920 is holding the battery now installing it 404 00:15:55,189 --> 00:15:53,440 back into the pallet you can't see a 405 00:15:57,110 --> 00:15:55,199 whole lot more than battery 406 00:15:59,670 --> 00:15:57,120 so it's really important for 407 00:16:02,470 --> 00:15:59,680 our other crew member mike in this case 408 00:16:07,990 --> 00:16:05,430 the battery into the slot without 409 00:16:09,990 --> 00:16:08,000 hitting any of the other equipment 410 00:16:11,670 --> 00:16:10,000 in between the first and second battery 411 00:16:13,910 --> 00:16:11,680 on the pallet there we need to 412 00:16:15,509 --> 00:16:13,920 reposition our foot restraint and then 413 00:16:17,430 --> 00:16:15,519 reposition the pallet 414 00:16:19,030 --> 00:16:17,440 that's to keep that bottom keel pin on 415 00:16:21,350 --> 00:16:19,040 the pallet from 416 00:16:22,949 --> 00:16:21,360 getting too close to the truss 417 00:16:25,269 --> 00:16:22,959 once that's complete we go ahead and 418 00:16:26,629 --> 00:16:25,279 guide the pallet back in again remove 419 00:16:28,150 --> 00:16:26,639 the battery 420 00:16:31,110 --> 00:16:28,160 and then once more 421 00:16:33,509 --> 00:16:31,120 shepard it over to its install location 422 00:16:35,590 --> 00:16:33,519 on the truss 423 00:16:37,590 --> 00:16:35,600 and then one more time here 424 00:16:39,749 --> 00:16:37,600 we'll move our foot restraint 425 00:16:41,910 --> 00:16:39,759 remove the third battery 426 00:16:44,069 --> 00:16:41,920 from the truss shepherd it back over to 427 00:16:45,189 --> 00:16:44,079 the pallet 428 00:16:46,790 --> 00:16:45,199 and then 429 00:16:49,189 --> 00:16:46,800 mike or i'm sorry 430 00:16:55,350 --> 00:16:49,199 steve will install that battery 431 00:16:59,030 --> 00:16:56,949 okay one more time we'll guide the 432 00:17:01,829 --> 00:16:59,040 pallet 433 00:17:03,590 --> 00:17:01,839 up to the next battery 434 00:17:05,510 --> 00:17:03,600 so here you can see the thermal comer 435 00:17:07,669 --> 00:17:05,520 closing on the second battery guide the 436 00:17:10,069 --> 00:17:07,679 pallet down 437 00:17:11,750 --> 00:17:10,079 install the handling aids and then again 438 00:17:14,309 --> 00:17:11,760 remove the battery 439 00:17:16,470 --> 00:17:14,319 from the pallet 440 00:17:18,230 --> 00:17:16,480 and shepard it back over to the truss to 441 00:17:19,829 --> 00:17:18,240 install it so at this point we have 442 00:17:21,750 --> 00:17:19,839 three new batteries installed in the 443 00:17:24,230 --> 00:17:21,760 truss and two of the old batteries put 444 00:17:25,829 --> 00:17:24,240 back on the pallet for return to earth 445 00:17:28,390 --> 00:17:25,839 at the very end there the crew will 446 00:17:29,190 --> 00:17:28,400 retrieve that temp stowed battery 447 00:17:31,029 --> 00:17:29,200 and 448 00:17:33,669 --> 00:17:31,039 put it back into the pallet close up the 449 00:17:35,350 --> 00:17:33,679 mli 450 00:17:38,470 --> 00:17:35,360 and the arm will then maneuver away to a 451 00:17:42,950 --> 00:17:39,909 where it will back out of the way so we 452 00:17:45,750 --> 00:17:42,960 continue to rotate the solar arrays 453 00:17:47,110 --> 00:17:45,760 in between evas 2 and 3. 454 00:17:48,630 --> 00:17:47,120 when that's complete the crew is going 455 00:17:50,630 --> 00:17:48,640 to go ahead and 456 00:17:54,070 --> 00:17:50,640 do a couple of get-aheads for the next 457 00:17:56,390 --> 00:17:54,080 dva they'll reposition that ball stack 458 00:17:59,190 --> 00:17:56,400 at a different temp stow location 459 00:18:01,270 --> 00:17:59,200 they'll take the foot restraint move it 460 00:18:01,990 --> 00:18:01,280 up to the location that garrett will use 461 00:18:03,350 --> 00:18:02,000 it 462 00:18:05,029 --> 00:18:03,360 to remove the first battery from the 463 00:18:06,950 --> 00:18:05,039 truss on eba 3 464 00:18:08,789 --> 00:18:06,960 and then we have a couple of tool bags 465 00:18:10,230 --> 00:18:08,799 that we took out 466 00:18:11,270 --> 00:18:10,240 on this eva and we're actually going to 467 00:18:13,430 --> 00:18:11,280 leave those 468 00:18:14,870 --> 00:18:13,440 stowed outside in between so they'll 469 00:18:16,390 --> 00:18:14,880 stow those 470 00:18:23,029 --> 00:18:16,400 on the truss also 471 00:18:27,909 --> 00:18:26,230 okay for the third eva 472 00:18:29,669 --> 00:18:27,919 goal is to 473 00:18:32,070 --> 00:18:29,679 finish the r r of the remaining 474 00:18:34,230 --> 00:18:32,080 batteries on the pallet 475 00:18:36,390 --> 00:18:34,240 mike good and garrett riesman will be 476 00:18:37,909 --> 00:18:36,400 going out for this 477 00:18:40,390 --> 00:18:37,919 third eva 478 00:18:42,230 --> 00:18:40,400 with mike taking the lead 479 00:18:44,549 --> 00:18:42,240 we're going to start this eva in the 480 00:18:46,310 --> 00:18:44,559 same arm and pallet configuration that 481 00:18:52,310 --> 00:18:46,320 we did on the last eva we'll go ahead 482 00:18:56,630 --> 00:18:54,470 so again coming into the 483 00:18:58,470 --> 00:18:56,640 same work site 484 00:19:01,190 --> 00:18:58,480 not as much preparation as required on 485 00:19:03,270 --> 00:19:01,200 eba2 since everything's 486 00:19:06,070 --> 00:19:03,280 set up for us 487 00:19:07,990 --> 00:19:06,080 so here you can see 488 00:19:09,510 --> 00:19:08,000 garrett is hanging upside down there 489 00:19:11,190 --> 00:19:09,520 from his foot restraint in what we call 490 00:19:13,590 --> 00:19:11,200 the batman position to remove that first 491 00:19:15,750 --> 00:19:13,600 battery from the truss he'll hand it 492 00:19:18,070 --> 00:19:15,760 down the mic they temp stow it 493 00:19:20,710 --> 00:19:18,080 down there at the bottom 494 00:19:23,350 --> 00:19:20,720 and then they will translate 495 00:19:24,390 --> 00:19:23,360 over to the pallet 496 00:19:26,150 --> 00:19:24,400 again 497 00:19:28,310 --> 00:19:26,160 guide it in 498 00:19:29,750 --> 00:19:28,320 and start the 499 00:19:31,110 --> 00:19:29,760 removal process 500 00:19:33,669 --> 00:19:31,120 over again 501 00:19:37,350 --> 00:19:33,679 so here we have like this time is our 502 00:19:37,360 --> 00:19:42,390 pulling the battery out of the pallet 503 00:19:46,230 --> 00:19:44,710 and then the crew will again shepherd it 504 00:19:48,710 --> 00:19:46,240 down 505 00:19:53,990 --> 00:19:48,720 to the install location 506 00:19:54,000 --> 00:19:57,909 reposition the foot restraint 507 00:20:01,510 --> 00:19:58,950 and then 508 00:20:03,830 --> 00:20:01,520 garrett will ingress the foot restraint 509 00:20:05,110 --> 00:20:03,840 remove the fifth battery from the truss 510 00:20:07,830 --> 00:20:05,120 again shepherd it back over to the 511 00:20:09,909 --> 00:20:07,840 pallet 512 00:20:12,070 --> 00:20:09,919 install it for the return to earth 513 00:20:13,909 --> 00:20:12,080 and here you can see garrett 514 00:20:15,029 --> 00:20:13,919 practicing at the 515 00:20:21,990 --> 00:20:15,039 in the pool 516 00:20:25,990 --> 00:20:24,149 once that battery is complete again 517 00:20:27,990 --> 00:20:26,000 guide the pallet 518 00:20:29,510 --> 00:20:28,000 down to the 519 00:20:39,669 --> 00:20:29,520 position to remove the fifth battery 520 00:20:45,830 --> 00:20:41,270 i'll go ahead and 521 00:20:50,630 --> 00:20:47,909 as you can see it's very slow and 522 00:20:52,470 --> 00:20:50,640 meticulous process 523 00:20:54,149 --> 00:20:52,480 the back side of those batteries has 524 00:20:55,750 --> 00:20:54,159 cooling fins on it so the crew has to be 525 00:20:58,390 --> 00:20:55,760 very careful 526 00:21:03,110 --> 00:20:58,400 not to nick or ding 527 00:21:08,070 --> 00:21:05,350 again pallet backs away 528 00:21:10,230 --> 00:21:08,080 crew will shepherd the battery 529 00:21:12,549 --> 00:21:10,240 down to the install location here you 530 00:21:14,549 --> 00:21:12,559 can see garrett installing the battery 531 00:21:16,950 --> 00:21:14,559 into the truss and then mike again 532 00:21:18,630 --> 00:21:16,960 helping him guide it in there 533 00:21:20,630 --> 00:21:18,640 so it doesn't 534 00:21:22,470 --> 00:21:20,640 hit any of the side walls of the truss 535 00:21:27,270 --> 00:21:22,480 there like i said garrett can't see much 536 00:21:31,510 --> 00:21:28,630 once we're done with the fifth battery 537 00:21:33,350 --> 00:21:31,520 we'll rotate our foot restraint over 538 00:21:36,789 --> 00:21:33,360 to a position that garrett can pull the 539 00:21:43,270 --> 00:21:38,149 again shepherd that back up to the 540 00:21:43,280 --> 00:21:46,630 install it 541 00:21:51,669 --> 00:21:48,470 remove the handling aids 542 00:21:51,679 --> 00:21:55,430 and then again guide the pallet 543 00:22:01,510 --> 00:21:57,750 up to the position that he can pull the 544 00:22:14,870 --> 00:22:03,350 off the pallet for installation into the 545 00:22:18,149 --> 00:22:16,710 we expect these batteries 546 00:22:20,310 --> 00:22:18,159 to take somewhere in the neighborhood of 547 00:22:23,750 --> 00:22:20,320 45 to an hour 548 00:22:26,230 --> 00:22:23,760 for each pair of one from each 549 00:22:27,750 --> 00:22:26,240 one from the pallet one from the truss 550 00:22:29,430 --> 00:22:27,760 again when that six battery is out of 551 00:22:30,710 --> 00:22:29,440 the pallet 552 00:22:31,909 --> 00:22:30,720 garrett will go ahead and install that 553 00:22:33,990 --> 00:22:31,919 into the truss 554 00:22:35,510 --> 00:22:34,000 the crew will then retrieve the temp 555 00:22:38,470 --> 00:22:35,520 stowed battery 556 00:22:41,350 --> 00:22:38,480 shepard that back over to the pallet 557 00:22:43,909 --> 00:22:41,360 install it remove the handling aids for 558 00:22:45,430 --> 00:22:43,919 the final time close up the 559 00:22:47,669 --> 00:22:45,440 thermal cover 560 00:22:49,909 --> 00:22:47,679 and then they'll make sure that 561 00:22:51,350 --> 00:22:49,919 everything's tucked away 562 00:22:52,470 --> 00:22:51,360 for the pallets returned in the shuttle 563 00:22:54,710 --> 00:22:52,480 bay 564 00:22:56,230 --> 00:22:54,720 and that's basically just closing some 565 00:22:58,310 --> 00:22:56,240 quarter turn fasteners making sure all 566 00:22:59,990 --> 00:22:58,320 the coverings are down 567 00:23:02,149 --> 00:23:00,000 and then again the arm will move off to 568 00:23:03,350 --> 00:23:02,159 a clearance position 569 00:23:07,190 --> 00:23:03,360 uh 570 00:23:09,750 --> 00:23:07,200 relocated down the truss so that it can 571 00:23:12,149 --> 00:23:09,760 be put back in the payload bay 572 00:23:14,230 --> 00:23:12,159 at this point the crew is going to 573 00:23:15,669 --> 00:23:14,240 gather up those gap spanner chains that 574 00:23:16,870 --> 00:23:15,679 they installed back at the beginning of 575 00:23:18,230 --> 00:23:16,880 eva2 576 00:23:20,470 --> 00:23:18,240 we're going to grab one of the foot 577 00:23:22,630 --> 00:23:20,480 restraints that we have out there we are 578 00:23:25,430 --> 00:23:22,640 leaving one out for use 579 00:23:27,669 --> 00:23:25,440 on a later shuttle mission 580 00:23:29,430 --> 00:23:27,679 and we will take the 581 00:23:31,430 --> 00:23:29,440 foot restraint the gap spanner chains 582 00:23:33,909 --> 00:23:31,440 and then the two tool bags that we also 583 00:23:35,190 --> 00:23:33,919 had taken out there on eba to 584 00:23:37,190 --> 00:23:35,200 bring everything 585 00:23:39,190 --> 00:23:37,200 back in board 586 00:23:41,029 --> 00:23:39,200 we're going to drop the foot restraint 587 00:23:42,230 --> 00:23:41,039 off 588 00:23:43,990 --> 00:23:42,240 on the 589 00:23:45,430 --> 00:23:44,000 port seat of cart that's one of the 590 00:23:47,190 --> 00:23:45,440 carts attached there to the mobile 591 00:23:48,789 --> 00:23:47,200 transporter 592 00:23:50,870 --> 00:23:48,799 and at this point 593 00:23:52,549 --> 00:23:50,880 if is time remaining 594 00:23:55,029 --> 00:23:52,559 in the eva 595 00:23:57,029 --> 00:23:55,039 we'll go ahead and translate 596 00:23:58,710 --> 00:23:57,039 down to the shuttle 597 00:24:01,430 --> 00:23:58,720 we have a 598 00:24:02,710 --> 00:24:01,440 grapple fixture that we flew up on the 599 00:24:05,669 --> 00:24:02,720 port side 600 00:24:08,149 --> 00:24:05,679 of the shuttle payload bay 601 00:24:09,190 --> 00:24:08,159 so the crew will translate down on their 602 00:24:11,909 --> 00:24:09,200 way 603 00:24:14,310 --> 00:24:11,919 grab a handling aid 604 00:24:15,750 --> 00:24:14,320 that they can install onto the face of 605 00:24:17,669 --> 00:24:15,760 that 606 00:24:19,909 --> 00:24:17,679 grapple fixture 607 00:24:21,830 --> 00:24:19,919 once they have the handling aid 608 00:24:23,110 --> 00:24:21,840 installed 609 00:24:24,390 --> 00:24:23,120 you can see here in the video that's 610 00:24:26,149 --> 00:24:24,400 what they're doing right now is putting 611 00:24:27,669 --> 00:24:26,159 that handling aid on 612 00:24:30,950 --> 00:24:27,679 once that is installed they'll work 613 00:24:32,950 --> 00:24:30,960 together to remove four fasteners 614 00:24:35,350 --> 00:24:32,960 here they are driving 615 00:24:37,110 --> 00:24:35,360 those fasteners to release them 616 00:24:40,950 --> 00:24:37,120 remove the four fasteners that hold the 617 00:24:42,950 --> 00:24:40,960 grapple fixture to the payload bay wall 618 00:24:45,029 --> 00:24:42,960 pull it off 619 00:24:47,029 --> 00:24:45,039 and then 620 00:24:48,710 --> 00:24:47,039 we'll actually use that handling aid 621 00:24:49,909 --> 00:24:48,720 allows us to 622 00:24:51,830 --> 00:24:49,919 stow 623 00:24:54,230 --> 00:24:51,840 that grapple fixture onto 624 00:24:57,110 --> 00:24:54,240 mike good's body restraint tether 625 00:24:58,789 --> 00:24:57,120 on the left side of his spacesuit 626 00:25:00,950 --> 00:24:58,799 they'll then 627 00:25:02,470 --> 00:25:00,960 start the long translation from the 628 00:25:04,230 --> 00:25:02,480 shuttle payload bay back over to the 629 00:25:06,950 --> 00:25:04,240 airlock and we're actually going to take 630 00:25:10,230 --> 00:25:06,960 that grapple fixture back inside 631 00:25:11,830 --> 00:25:10,240 uh where it will be integrated onto some 632 00:25:13,750 --> 00:25:11,840 russian hardware 633 00:25:15,110 --> 00:25:13,760 and the plan is to take 634 00:25:17,029 --> 00:25:15,120 that full assembly with the grapple 635 00:25:19,269 --> 00:25:17,039 fixture and the russian hardware back 636 00:25:22,310 --> 00:25:19,279 out later on a stage eba 637 00:25:24,149 --> 00:25:22,320 front installation onto the fgb so it 638 00:25:27,029 --> 00:25:24,159 would give us a new arm base 639 00:25:30,149 --> 00:25:28,630 and when that is complete the crew is 640 00:25:35,990 --> 00:25:30,159 going to go go ahead and come back 641 00:25:40,149 --> 00:25:38,070 that go ahead and concludes the summary 642 00:25:42,950 --> 00:25:40,159 of the eba so if there's any questions 643 00:25:44,230 --> 00:25:42,960 now i can go ahead and take those 644 00:25:45,350 --> 00:25:44,240 okay we'll start off with questions here 645 00:25:50,470 --> 00:25:45,360 at the johnson space center then we'll 646 00:25:52,950 --> 00:25:51,669 nothing here 647 00:25:54,149 --> 00:25:52,960 anybody 648 00:25:55,029 --> 00:25:54,159 sure 649 00:25:56,870 --> 00:25:55,039 um 650 00:25:57,909 --> 00:25:56,880 moving the big batteries right you all 651 00:25:59,830 --> 00:25:57,919 have done stuff like this before is 652 00:26:02,149 --> 00:25:59,840 there anything in your mind especially 653 00:26:03,909 --> 00:26:02,159 challenging about any of these tasks if 654 00:26:05,430 --> 00:26:03,919 being either the the escant you know 655 00:26:07,350 --> 00:26:05,440 clearance issue and making sure you get 656 00:26:09,190 --> 00:26:07,360 it out without dinging something or just 657 00:26:11,190 --> 00:26:09,200 moving these masses around 658 00:26:13,510 --> 00:26:11,200 yeah the challenge i mean especially 659 00:26:14,230 --> 00:26:13,520 with the escant is that the uh 660 00:26:15,750 --> 00:26:14,240 well 661 00:26:17,269 --> 00:26:15,760 one like for the boom i mean like i said 662 00:26:19,350 --> 00:26:17,279 it's eight foot long 663 00:26:21,350 --> 00:26:19,360 so i mean it's just a very large mass 664 00:26:22,870 --> 00:26:21,360 it's not very heavy 665 00:26:24,789 --> 00:26:22,880 but the crew just needs to be careful as 666 00:26:27,190 --> 00:26:24,799 they you know translate it around and we 667 00:26:29,110 --> 00:26:27,200 especially want to make sure we don't 668 00:26:30,950 --> 00:26:29,120 hit any of the other hardware on the 669 00:26:33,590 --> 00:26:30,960 pallet so that's why it's very important 670 00:26:35,830 --> 00:26:33,600 that steve helps garrett lift that boom 671 00:26:37,669 --> 00:26:35,840 up over the gold posts 672 00:26:39,750 --> 00:26:37,679 on the dexter platform 673 00:26:41,750 --> 00:26:39,760 and then when we translate the dish 674 00:26:43,190 --> 00:26:41,760 itself that dish is very fragile that's 675 00:26:45,350 --> 00:26:43,200 a graphite 676 00:26:47,669 --> 00:26:45,360 composite dish 677 00:26:49,269 --> 00:26:47,679 so you can see there on the video it's a 678 00:26:50,710 --> 00:26:49,279 very tight clearance 679 00:26:52,470 --> 00:26:50,720 when garrett goes ahead and pulls that 680 00:26:54,310 --> 00:26:52,480 out so he just needs to be very careful 681 00:26:56,070 --> 00:26:54,320 and then again 682 00:26:57,830 --> 00:26:56,080 when they go to install the dish onto 683 00:26:59,830 --> 00:26:57,840 the boom 684 00:27:01,190 --> 00:26:59,840 we've been told by the engineers 685 00:27:03,350 --> 00:27:01,200 that own that hardware that that's a 686 00:27:04,710 --> 00:27:03,360 very very sensitive interface and any 687 00:27:06,230 --> 00:27:04,720 scratches could 688 00:27:07,990 --> 00:27:06,240 degrade the signal so we need to be 689 00:27:10,230 --> 00:27:08,000 careful with that 690 00:27:11,830 --> 00:27:10,240 as far as the batteries 691 00:27:13,669 --> 00:27:11,840 like i said they are big and kind of 692 00:27:14,710 --> 00:27:13,679 unwieldy you can't see a you know a lot 693 00:27:16,470 --> 00:27:14,720 when you're 694 00:27:17,830 --> 00:27:16,480 actually holding the battery but one of 695 00:27:19,830 --> 00:27:17,840 the biggest challenges on that you can 696 00:27:21,669 --> 00:27:19,840 see it's a very repetitive process you 697 00:27:22,789 --> 00:27:21,679 know so the crew 698 00:27:23,990 --> 00:27:22,799 you know they've trained a lot but they 699 00:27:26,070 --> 00:27:24,000 need to really keep their head in the 700 00:27:27,909 --> 00:27:26,080 game you know to not get 701 00:27:29,430 --> 00:27:27,919 complacent and 702 00:27:30,549 --> 00:27:29,440 make sure they always remember where 703 00:27:33,269 --> 00:27:30,559 they are and 704 00:27:35,269 --> 00:27:33,279 tony antonelli our iv is very very good 705 00:27:37,350 --> 00:27:35,279 at uh keeping everybody you know in the 706 00:27:39,029 --> 00:27:37,360 game and making sure that we're 707 00:27:41,190 --> 00:27:39,039 you know doing what we're supposed to do 708 00:27:43,190 --> 00:27:41,200 and one more for me um i'm given that 709 00:27:44,710 --> 00:27:43,200 you've got three guys doing two each 710 00:27:46,389 --> 00:27:44,720 and everybody's a lead on one is there a 711 00:27:47,750 --> 00:27:46,399 reason for that or is that just 712 00:27:48,870 --> 00:27:47,760 just to spread it spread it around a 713 00:27:50,630 --> 00:27:48,880 little bit i wasn't sure about the 714 00:27:51,909 --> 00:27:50,640 reason um it was really just to spread 715 00:27:53,750 --> 00:27:51,919 it around a little bit i mean it's rare 716 00:27:54,950 --> 00:27:53,760 that you have three veteran spacewalkers 717 00:27:56,710 --> 00:27:54,960 on one mission 718 00:27:58,389 --> 00:27:56,720 um so they each bring something 719 00:28:01,430 --> 00:27:58,399 different to the table you know steve 720 00:28:03,110 --> 00:28:01,440 has done the assembly missions before 721 00:28:04,870 --> 00:28:03,120 mike has done the hubble missions and 722 00:28:06,070 --> 00:28:04,880 garrett actually lived onboard space 723 00:28:07,190 --> 00:28:06,080 station so they each bring something 724 00:28:08,389 --> 00:28:07,200 different so 725 00:28:11,669 --> 00:28:08,399 we only thought it was fair that they 726 00:28:13,269 --> 00:28:11,679 each get to take the lead on an eva 727 00:28:14,630 --> 00:28:13,279 okay that's it from here let's go down 728 00:28:18,549 --> 00:28:14,640 to the kennedy space center in florida 729 00:28:23,430 --> 00:28:21,029 marcia dunn associated press 730 00:28:25,029 --> 00:28:23,440 for the battery work some of that prep 731 00:28:27,029 --> 00:28:25,039 work i know was taken off the last 732 00:28:29,350 --> 00:28:27,039 flight due to some safety concerns and 733 00:28:32,710 --> 00:28:29,360 i'm wondering what changes were made 734 00:28:36,389 --> 00:28:32,720 to make it safe for the upcoming 735 00:28:37,909 --> 00:28:36,399 spacewalks that's a very good question 736 00:28:40,470 --> 00:28:37,919 yes the 737 00:28:42,830 --> 00:28:40,480 originally the relocation of the 738 00:28:45,269 --> 00:28:42,840 portable foot restraints in the gap 739 00:28:48,230 --> 00:28:45,279 spanners along with the breaking of the 740 00:28:50,070 --> 00:28:48,240 torque on the six batteries on the truss 741 00:28:51,830 --> 00:28:50,080 was to take place by the 742 00:28:54,630 --> 00:28:51,840 last shuttle flight 743 00:28:57,590 --> 00:28:56,310 the reason they decided not to do that 744 00:28:59,510 --> 00:28:57,600 was because of 745 00:29:01,590 --> 00:28:59,520 an uncertainty 746 00:29:02,710 --> 00:29:01,600 with an electrical shock hazard that we 747 00:29:05,269 --> 00:29:02,720 had 748 00:29:07,750 --> 00:29:05,279 and so we are flying up 749 00:29:09,830 --> 00:29:07,760 new mini workstations which is the 750 00:29:11,430 --> 00:29:09,840 piece of hardware that the crew wears on 751 00:29:13,029 --> 00:29:11,440 the front of the spacesuits that holds 752 00:29:14,149 --> 00:29:13,039 the tools 753 00:29:15,909 --> 00:29:14,159 for them 754 00:29:18,710 --> 00:29:15,919 those new base plates 755 00:29:20,070 --> 00:29:18,720 are electrically isolated from the suits 756 00:29:21,830 --> 00:29:20,080 and 757 00:29:23,750 --> 00:29:21,840 that will reduce the 758 00:29:25,909 --> 00:29:23,760 hazard back into an acceptable range 759 00:29:29,430 --> 00:29:25,919 when our crew performs the uh that 760 00:29:33,669 --> 00:29:30,710 will they be taking any other 761 00:29:36,310 --> 00:29:33,679 precautions aside from that to 762 00:29:38,549 --> 00:29:36,320 further reduce the risk or is that 763 00:29:42,070 --> 00:29:38,559 enough in terms of the 764 00:29:44,549 --> 00:29:42,080 safety concerns we had we had other 765 00:29:48,389 --> 00:29:44,559 mitigation 766 00:29:50,470 --> 00:29:48,399 that's to always make sure that their 767 00:29:52,630 --> 00:29:50,480 their wrist rings are covered by their 768 00:29:54,389 --> 00:29:52,640 gauntlets 769 00:29:55,350 --> 00:29:54,399 other than that we we don't have any 770 00:29:59,669 --> 00:29:55,360 other 771 00:30:03,830 --> 00:30:01,750 and and lastly for the last question 772 00:30:05,750 --> 00:30:03,840 from here how many um 773 00:30:08,389 --> 00:30:05,760 how what is the distance between that 774 00:30:10,470 --> 00:30:08,399 work site on the far port side and the 775 00:30:12,389 --> 00:30:10,480 airlock in terms of the distance 776 00:30:14,789 --> 00:30:12,399 traveled by the crew not you know as the 777 00:30:16,950 --> 00:30:14,799 bird fly so to speak but from 778 00:30:18,630 --> 00:30:16,960 hand over hand crawling how many feet is 779 00:30:19,590 --> 00:30:18,640 that do you know offhand 780 00:30:21,190 --> 00:30:19,600 um 781 00:30:24,310 --> 00:30:21,200 i don't let me see i don't i don't know 782 00:30:25,750 --> 00:30:24,320 exactly off hand but i know we're 783 00:30:27,909 --> 00:30:25,760 almost towards the end of our tethers 784 00:30:29,909 --> 00:30:27,919 we're using an 85 foot safety tether to 785 00:30:31,590 --> 00:30:29,919 get out 786 00:30:33,269 --> 00:30:31,600 to an anchor point where we're we're 787 00:30:35,269 --> 00:30:33,279 dropping the anchors of those tethers 788 00:30:37,350 --> 00:30:35,279 off and then we 789 00:30:38,909 --> 00:30:37,360 go another 85 feet 790 00:30:41,830 --> 00:30:38,919 from there so it's at 791 00:30:44,470 --> 00:30:41,840 170 feet and then we have a 55 foot 792 00:30:46,230 --> 00:30:44,480 tether connected to our 85 foot tethers 793 00:30:48,549 --> 00:30:46,240 so that would be some place in the 794 00:30:51,430 --> 00:30:48,559 neighborhood of 220 feet that the crew 795 00:30:54,549 --> 00:30:51,440 is translating 796 00:30:56,950 --> 00:30:55,830 okay i think that's it from the kennedy 797 00:31:02,310 --> 00:30:56,960 space center let's go to nasa 798 00:31:07,350 --> 00:31:04,310 thank you it's uh tarek malek from 799 00:31:08,789 --> 00:31:07,360 space.com and uh you know i it seemed 800 00:31:10,470 --> 00:31:08,799 you mentioned the the repetitive nature 801 00:31:13,269 --> 00:31:10,480 of the battery working and that it's 802 00:31:15,669 --> 00:31:13,279 going to take a couple spacewalks to um 803 00:31:18,470 --> 00:31:15,679 to complete i'm just wondering how um 804 00:31:21,029 --> 00:31:18,480 how you do keep them focused on what it 805 00:31:23,669 --> 00:31:21,039 what looks to be a pretty tedious 806 00:31:25,830 --> 00:31:23,679 task at the end of the space station and 807 00:31:27,830 --> 00:31:25,840 i guess how many runs that they do each 808 00:31:29,909 --> 00:31:27,840 of the spacewalkers perform 809 00:31:32,230 --> 00:31:29,919 to rehearse those those 810 00:31:33,509 --> 00:31:32,240 actions thanks 811 00:31:35,750 --> 00:31:33,519 good question 812 00:31:37,350 --> 00:31:35,760 uh we actually as far as timeline runs 813 00:31:39,110 --> 00:31:37,360 for the batteries 814 00:31:40,789 --> 00:31:39,120 we did six 815 00:31:42,549 --> 00:31:40,799 runs in the water there was actually an 816 00:31:44,230 --> 00:31:42,559 another few 817 00:31:45,509 --> 00:31:44,240 runs that we did just for development to 818 00:31:47,509 --> 00:31:45,519 make sure we 819 00:31:50,630 --> 00:31:47,519 we had a good technique for training the 820 00:31:55,110 --> 00:31:52,630 as far as keeping the crew on game i 821 00:31:56,870 --> 00:31:55,120 mean when you're holding a big 365 pound 822 00:31:57,830 --> 00:31:56,880 battery i think they're they're very 823 00:32:00,630 --> 00:31:57,840 aware 824 00:32:02,710 --> 00:32:00,640 um how important it is um to stay with 825 00:32:04,950 --> 00:32:02,720 it but like i said our our iv tony 826 00:32:07,990 --> 00:32:04,960 antonelli um he really 827 00:32:11,110 --> 00:32:08,000 you know um keeps the crews the crew 828 00:32:12,470 --> 00:32:11,120 talking he makes sure makes sure that uh 829 00:32:14,389 --> 00:32:12,480 you know that 830 00:32:16,789 --> 00:32:14,399 that the guy on the pallet is 831 00:32:18,789 --> 00:32:16,799 communicating clearly to piers 832 00:32:19,750 --> 00:32:18,799 operating it from the arm so 833 00:32:21,110 --> 00:32:19,760 um 834 00:32:24,149 --> 00:32:21,120 we haven't 835 00:32:26,230 --> 00:32:24,159 and executed this but i don't think the 836 00:32:29,830 --> 00:32:26,240 crew is going to have any problems 837 00:32:31,029 --> 00:32:29,840 keeping their head in the game 838 00:32:32,710 --> 00:32:31,039 i think that's it from headquarters 839 00:32:37,830 --> 00:32:32,720 let's come back here for some follow-ups 840 00:32:41,269 --> 00:32:39,190 yeah just have a quick one uh mark 841 00:32:42,789 --> 00:32:41,279 kirkman inner space news can you tell me 842 00:32:45,190 --> 00:32:42,799 where you stand on eva training at this 843 00:32:48,070 --> 00:32:45,200 point are any more nbl runs uh vr lab 844 00:32:50,789 --> 00:32:48,080 runs or sims left nope at this point 845 00:32:52,310 --> 00:32:50,799 we've completed all of the mbl runs and 846 00:32:53,750 --> 00:32:52,320 it's a good point we did because this 847 00:32:55,669 --> 00:32:53,760 was so hard to train in the pool we 848 00:32:57,750 --> 00:32:55,679 pretty much coupled every 849 00:32:59,430 --> 00:32:57,760 pool run with a run in the virtual 850 00:33:01,029 --> 00:32:59,440 reality lab so 851 00:33:04,070 --> 00:33:01,039 but at this point everything is complete 852 00:33:05,509 --> 00:33:04,080 the crew's fully trained and ready to go 853 00:33:07,750 --> 00:33:05,519 okay bill 854 00:33:09,029 --> 00:33:07,760 yeah just one more follow-up on marsha's 855 00:33:10,470 --> 00:33:09,039 question about the shock hazard i was 856 00:33:12,950 --> 00:33:10,480 never clear when they told us about this 857 00:33:14,310 --> 00:33:12,960 last time was this an issue that your 858 00:33:16,149 --> 00:33:14,320 suit takes a charge and you have a 859 00:33:17,669 --> 00:33:16,159 malfunction or does this kill somebody i 860 00:33:19,269 --> 00:33:17,679 mean i never really understood the real 861 00:33:20,789 --> 00:33:19,279 nature of the threat 862 00:33:22,149 --> 00:33:20,799 um 863 00:33:24,389 --> 00:33:22,159 i'm probably not the best person to 864 00:33:26,310 --> 00:33:24,399 answer that but in my understanding is 865 00:33:29,430 --> 00:33:26,320 it's not something that's going to kill 866 00:33:31,590 --> 00:33:29,440 somebody but it could cause you to 867 00:33:34,230 --> 00:33:31,600 involuntarily move 868 00:33:35,590 --> 00:33:34,240 maybe cause somebody to drop a battery 869 00:33:39,110 --> 00:33:35,600 lose their grip 870 00:33:41,029 --> 00:33:39,120 on the trust something like that 871 00:33:42,549 --> 00:33:41,039 okay is that it from here 872 00:33:44,549 --> 00:33:42,559 all right
