00:01:12,950 --> 00:01:10,640
outside of moscow as they continue to

35
00:01:15,270 --> 00:01:12,960
take a look at the windows just always

36
00:01:17,190 --> 00:01:15,280
checking for any possible imperfections

37
00:01:18,950 --> 00:01:17,200
or damage from potential micro

ball sized objects which are used for a

151
00:05:17,510 --> 00:05:15,440
number of different exciting experiments

152
00:05:20,390 --> 00:05:17,520
including formation flying in the

153
00:05:22,310 --> 00:05:20,400
development of algorithms by

154
00:05:24,310 --> 00:05:22,320
students and teams from schools across

155
00:05:26,469 --> 00:05:24,320
the country they get a chance to follow

156
00:05:29,189 --> 00:05:26,479
along with the expedition astronauts

157
00:05:30,629 --> 00:05:29,199
watching as these satellites conduct

158
00:05:33,110 --> 00:05:30,639
various flying

investigation

194
00:06:43,830 --> 00:06:42,080
looking into the various dynamic loads

195
00:06:45,749 --> 00:06:43,840
that the international space station's

196
00:06:46,710 --> 00:06:45,759
russian segment structure is subjected

197
00:06:49,430 --> 00:06:46,720
to

198
00:06:51,830 --> 00:06:49,440
during different dynamic operations

199
00:06:53,909 --> 00:06:51,840
some of these dynamic operations include

200
00:06:56,469 --> 00:06:53,919
docking and visiting vehicles

201
00:06:59,029 --> 00:06:56,479
also station reboots

202
00:07:01,990 --> 00:06:59,039
the physical exercise of the astronauts

203
00:07:04,390 --> 00:07:02,000
themselves and also up any extra

204
00:07:06,390 --> 00:07:04,400
vehicular activity or spacewalks uh the

205
00:07:07,510 --> 00:07:06,400
russians having just completed one back

206
00:07:09,990 --> 00:07:07,520
in uh

207
00:07:11,749 --> 00:07:10,000
late june and the us

208
00:07:14,629 --> 00:07:11,759
os crew members getting ready to

209
00:07:17,029 --> 00:07:14,639
complete two over the next two weeks

210
00:07:19,110 --> 00:07:17,039
european astronaut luca parmitano

211
00:07:21,350 --> 00:07:19,120
joining cassidy and much of his

212
00:07:23,749 --> 00:07:21,360
activities this week as they continue to

213
00:07:25,510 --> 00:07:23,759
prepare for those uh two upcoming

214
00:07:27,990 --> 00:07:25,520
spacewalks

215
00:07:30,390 --> 00:07:28,000
he'll be doing a an on-orbit fit check

216
00:07:33,189 --> 00:07:30,400
verification of his own spacesuit

217
00:07:34,870 --> 00:07:33,199
along with cassidy he'll also be

218
00:07:36,710 --> 00:07:34,880
responsible for doing a checkout of

219
00:07:40,550 --> 00:07:36,720
their safer devices

220
00:07:42,870 --> 00:07:40,560
the safer are small nitrogen gas-powered

221
00:07:44,950 --> 00:07:42,880
backpacks that the astronauts wear

222
00:07:46,629 --> 00:07:44,960
sort of acting as their life jacket

223
00:07:49,110 --> 00:07:46,639
during these

224
00:07:50,790 --> 00:07:49,120
spacewalks aside from the regular

225
00:07:52,390 --> 00:07:50,800
contingent of tethers and hand grips

226
00:07:54,550 --> 00:07:52,400
that they use to keep attached to the

227
00:07:56,230 --> 00:07:54,560
station the safer can serve as a last

228
00:07:58,790 --> 00:07:56,240
resort should the astronauts begin to

229
00:08:00,790 --> 00:07:58,800
float away free from the station getting

230
00:08:02,710 --> 00:08:00,800
them back to safety

231
00:08:04,629 --> 00:08:02,720
parmitano also

232
00:08:06,710 --> 00:08:04,639
scheduled to do his own monthly periodic

233
00:08:07,670 --> 00:08:06,720
fitness evaluation also on that sevis

234
00:08:08,869 --> 00:08:07,680
device

235
00:08:10,710 --> 00:08:08,879
and then doing

236
00:08:13,189 --> 00:08:10,720
some pretty major

237
00:08:15,430 --> 00:08:13,199
maintenance tasks on board the station

238
00:08:17,270 --> 00:08:15,440
for their various uh eclipse or the

239
00:08:19,830 --> 00:08:17,280
environmental uh

240
00:08:22,309 --> 00:08:19,840
regeneration systems he'll be inside of

241
00:08:24,869 --> 00:08:22,319
the european columbus module

242
00:08:27,670 --> 00:08:24,879
working on removing and replacing the

243
00:08:28,869 --> 00:08:27,680
columbus's water processing assembly

244
00:08:30,950 --> 00:08:28,879
number two

245
00:08:32,870 --> 00:08:30,960
and also replacing some

246
00:08:35,269 --> 00:08:32,880
items inside of the waste and hygiene

247
00:08:36,949 --> 00:08:35,279
compartment he'll be replacing some of

248
00:08:39,029 --> 00:08:36,959
the piping between the pump separator

249
00:08:42,070 --> 00:08:39,039
and the pre-treat and water pump

250
00:08:43,509 --> 00:08:42,080
then our final expedition 36 crew member

251
00:08:45,190 --> 00:08:43,519

253
00:08:48,310 --> 00:08:46,800
checkouts over

254
00:08:49,509 --> 00:08:48,320
the rest of the week

255
00:08:51,030 --> 00:08:49,519
she'll be

256
00:08:53,269 --> 00:08:51,040
responsible for conducting all the

257
00:08:55,750 --> 00:08:53,279
robotic operations during cassidy and

258
00:08:57,590 --> 00:08:55,760
luca parmitano's spacewalks controlling

259
00:09:00,150 --> 00:08:57,600
the station's canada arm tour the

260
00:09:02,470 --> 00:09:00,160
robotic arm she'll be doing a checkout

261
00:09:04,870 --> 00:09:02,480
of that display and control panel also

262
00:09:07,829 --> 00:09:04,880
continuing with a lot of

263
00:09:10,389 --> 00:09:07,839
giving a hand with all the space suit or

264
00:09:12,949 --> 00:09:10,399
the emu preparations and going over all

265
00:09:15,509 --> 00:09:12,959
the space walk procedures

266
00:09:17,590 --> 00:09:15,519
she'll be doing her own review of the

267
00:09:19,990 --> 00:09:17,600
space station's robotic arm of the

268
00:09:21,750 --> 00:09:20,000
remote manipulator systems doug

269
00:09:23,670 --> 00:09:21,760
the doug again standing for dynamic

270
00:09:25,829 --> 00:09:23,680
onboard ubiquitous graphics she'll be

271
00:09:28,070 --> 00:09:25,839
doing that review with uh spacewalk

272
00:09:30,470 --> 00:09:28,080
officers down here on the ground

273
00:09:32,870 --> 00:09:30,480
aside from that uh quite a bit of

274
00:09:34,710 --> 00:09:32,880
experiment work for her

275
00:09:37,910 --> 00:09:34,720
aside from

276
00:09:39,269 --> 00:09:37,920
doing some earth cam setup the earth cam

277
00:09:41,110 --> 00:09:39,279
is the earth knowledge acquired by

278
00:09:42,949 --> 00:09:41,120
middle school students i shall be

279
00:09:45,030 --> 00:09:42,959
setting that up

280
00:09:46,230 --> 00:09:45,040
towards the end of the week

281
00:09:47,750 --> 00:09:46,240
and

282
00:09:49,910 --> 00:09:47,760
preparing that for middle school

283
00:09:52,310 --> 00:09:49,920
students to control and take photos of

284
00:09:53,910 --> 00:09:52,320
various locations around the world

285
00:09:56,310 --> 00:09:53,920
she'll also be working inside of the

286
00:09:58,389 --> 00:09:56,320

replacing one of the multi-user droplet

288
00:10:02,949 --> 00:10:01,120
combustion apparatus fuel reservoirs

289
00:10:04,790 --> 00:10:02,959
these reservoirs are used to contain the

290
00:10:07,110 --> 00:10:04,800
liquid fuel used during droplet

291
00:10:08,870 --> 00:10:07,120
combustion experiments that combustion

292
00:10:11,190 --> 00:10:08,880
