1
00:00:00,000 --> 00:00:01,468
>> Good morning and welcome to

2
00:00:01,468 --> 00:00:03,303
mission control Houston and

3
00:00:03,303 --> 00:00:04,738
international space station

4
00:00:04,738 --> 00:00:06,005
flight control room.

5
00:00:06,005 --> 00:00:07,440
The specialists here are

6
00:00:07,440 --> 00:00:09,576
watching over the operation of

7
00:00:09,576 --> 00:00:14,280
the system and the crew members

8
00:00:14,280 --> 00:00:16,716
as they near the end of a busy

9
00:00:16,716 --> 00:00:17,984
workweek.

10
00:00:17,984 --> 00:00:19,285
They have been busy with science

11
00:00:19,285 --> 00:00:21,254
and maintenance this week.

12
00:00:21,254 --> 00:00:22,122
As well as getting ready for

13
00:00:22,122 --> 00:00:23,957
some special activities next

14
00:00:23,957 --> 00:00:24,991
week.

15
00:00:24,991 --> 00:00:26,760
An U.S. spacewalk on Wednesday.

16
00:00:26,760 --> 00:00:34,667
And the arrival of an uncrewed

17
00:00:34,667 --> 00:00:38,638
soyu spacecraft.

18
00:00:38,638 --> 00:00:39,773
>> This week the crew

19
00:00:39,773 --> 00:00:43,343
appropriate for an up coming

20
00:00:43,343 --> 00:00:43,910
spacewalk.

21
00:00:43,910 --> 00:00:47,814
Nick Haig and Andrew Morgan

22
00:00:47,814 --> 00:00:50,250
reviewed procedures for a

23
00:00:50,250 --> 00:00:52,085
spacewalk.

24
00:00:52,085 --> 00:00:53,653
The system sin tallalation of

25
00:00:53,653 --> 00:00:55,789
the international docket adapter

26
00:00:55,789 --> 00:00:58,491
to the space station.

27
00:00:58,491 --> 00:01:00,059
It will provide a sect docking

28
00:01:00,059 --> 00:01:01,628
port to accommodate the future

29
00:01:01,628 --> 00:01:04,864
arrivals of commercial crews

30
00:01:04,864 --> 00:01:05,899
spacecraft.

31
00:01:05,899 --> 00:01:08,401
This will be the third spacewalk

32
00:01:08,401 --> 00:01:10,437
for Haig and the first for

33
00:01:10,437 --> 00:01:11,004
Morgan.

34
00:01:11,004 --> 00:01:19,979
The launch of the soyuz is

35
00:01:19,979 --> 00:01:22,115
helping the vehicle in

36
00:01:22,115 --> 00:01:23,850
preparation for human launches

37
00:01:23,850 --> 00:01:26,553
beginning next March.

38
00:01:26,553 --> 00:01:28,087
This booster has been used for

39
00:01:28,087 --> 00:01:30,690
cargo vehicle launches but not

40
00:01:30,690 --> 00:01:38,598
yet for human space trips.

41
00:01:38,598 --> 00:01:40,567
It will automatically dock to

42
00:01:40,567 --> 00:01:42,202
the station two days after it

43
00:01:42,202 --> 00:01:44,737
launches and two days at the

44
00:01:44,737 --> 00:01:48,107
station before it is orbited for

45
00:01:48,107 --> 00:01:51,511
landing in Kazakhstan.

46
00:01:51,511 --> 00:01:57,383
The key is fuel.

47
00:01:57,383 --> 00:01:58,918
Which is just as true in space

48
00:01:58,918 --> 00:02:01,754
as it is on earth.

49
00:02:01,754 --> 00:02:06,192
The technology to replenish the

50
00:02:06,192 --> 00:02:11,998
crew does not currently exist.

51
00:02:11,998 --> 00:02:15,001
This project will enable longer

52
00:02:15,001 --> 00:02:18,838
duration of space exploration.

53
00:02:18,838 --> 00:02:22,408
This will store cryogenic fluid

54
00:02:22,408 --> 00:02:25,111
in space, and will demonstrate

55
00:02:25,111 --> 00:02:29,215
the efficient use of importable

56
00:02:29,215 --> 00:02:30,750
consumables.

57
00:02:30,750 --> 00:02:32,785
It could apply to the missions

58
00:02:32,785 --> 00:02:34,787
to moon and mars.

59
00:02:34,787 --> 00:02:38,091
Keep sending these questions to

60
00:02:38,091 --> 00:02:40,326
#ask NASA.

61
00:02:40,326 --> 00:02:52,105
We'll see you next week.

62
00:02:52,105 --> 00:02:53,373
>> Here are just a couple of

63
00:02:53,373 --> 00:02:56,075
NASA TV programming notes.

64
00:02:56,075 --> 00:02:57,810
Today at 1:00 Houston time,

65
00:02:57,810 --> 00:03:01,781
we'll air a briefing previewing

66
00:03:01,781 --> 00:03:03,049
of the spacewalk.

67
00:03:03,049 --> 00:03:06,452
The coverage starts this

68
00:03:06,452 --> 00:03:07,754
Wednesday morning at 5:30

69
00:03:07,754 --> 00:03:08,621
central time.

70
00:03:08,621 --> 00:03:10,456
The spacewalk should start about

71
00:03:10,456 --> 00:03:12,025
7:20.

72
00:03:12,025 --> 00:03:13,459
Later the same day we'll have

73
00:03:13,459 --> 00:03:14,861
live coverage of the launch of

74
00:03:14,861 --> 00:03:20,733
the uncrewed 60 soyuz.

75
00:03:20,733 --> 00:03:24,704
That begins at 6:15 Houston time

76
00:03:24,704 --> 00:03:25,405
Wednesday.

77
00:03:25,405 --> 00:03:27,106
Then we'll be back next Friday

78
00:03:27,106 --> 00:03:29,375
night, the 23rd, with coverage

79
00:03:29,375 --> 00:03:32,245
of 60 s dock together station.

80
00:03:32,245 --> 00:03:33,479
That's scheduled to take place a

81
00:03:33,479 --> 00:03:35,348
half hour after midnight next

82
00:03:35,348 --> 00:03:36,215
Saturday morning.

83
00:03:36,215 --> 00:03:37,517
The spacewalk next week will be

84
00:03:37,517 --> 00:03:39,085
the third in the career of

85
00:03:39,085 --> 00:03:41,087
flight engineers Nick Haig.

86
00:03:41,087 --> 00:03:43,056
You probably know he's a colonel

87
00:03:43,056 --> 00:03:54,968
in the U.S. air force and an

88
00:03:54,968 --> 00:04:03,476
astronautcal engineer by

89
00:04:03,476 --> 00:04:05,044
training.

90
00:04:05,044 --> 00:04:07,614
>> So we're an air force family.

91
00:04:07,614 --> 00:04:08,781
Something that you may not know

92
00:04:08,781 --> 00:04:09,482
about us.

93
00:04:09,482 --> 00:04:11,317
I met my wife at the air force

94
00:04:11,317 --> 00:04:14,020
academy back in 1996 when we

95
00:04:14,020 --> 00:04:16,322
were in the same squadron.

96
00:04:16,322 --> 00:04:17,957
I was from Kansas.

97
00:04:17,957 --> 00:04:18,858
She was from New York City.

98
00:04:18,858 --> 00:04:21,027
We never would have cross paths

99
00:04:21,027 --> 00:04:22,996
had it not been for the air

100
00:04:22,996 --> 00:04:23,863
force academy.

101
00:04:23,863 --> 00:04:25,298
So the question I get all the

102
00:04:25,298 --> 00:04:31,571
time are you a "Star Trek" fan

103
00:04:31,571 --> 00:04:34,774
or are you a "Star Wars" fan.

104
00:04:34,774 --> 00:04:36,676
But rarely anyone asks me about

105
00:04:36,676 --> 00:04:38,811
Dr. "WHO."

106
00:04:38,811 --> 00:04:44,517
That's the show that I watched

107
00:04:44,517 --> 00:04:46,819
when I was young.

108
00:04:46,819 --> 00:04:49,856
"Dr. Who" was a staple when I

109
00:04:49,856 --> 00:04:51,324
was growing up.

110
00:04:51,324 --> 00:04:52,392
Something that my wife

111
00:04:52,392 --> 00:04:54,394
introduced me to is yoga.

112
00:04:54,394 --> 00:04:56,829
We're regular practitioners of

113
00:04:56,829 --> 00:04:58,097
yoga.

114
00:04:58,097 --> 00:04:59,532
I got to tell you that I'm

115
00:04:59,532 --> 00:05:01,367
extremely thankful that she got

116
00:05:01,367 --> 00:05:03,936
me hooked because being crammed

117
00:05:03,936 --> 00:05:07,340
up inside the module of the

118
00:05:07,340 --> 00:05:10,176
soyuz capsule with your knees in

119
00:05:10,176 --> 00:05:12,178
your chest for hours on end is

120
00:05:12,178 --> 00:05:13,913
easier ever putting yourself

121
00:05:13,913 --> 00:05:17,450
through a few hours of torture

122
00:05:17,450 --> 00:05:18,317
doing yoga.

123
00:05:18,317 --> 00:05:20,953
I don't know if torture was the

124
00:05:20,953 --> 00:05:21,554
right word.

125
00:05:21,554 --> 00:05:24,424
Growing up in a small school I

126
00:05:24,424 --> 00:05:26,392
got to play every sport.

127
00:05:26,392 --> 00:05:27,994
But the thing that really got me

128
00:05:27,994 --> 00:05:30,129
hooked, and was my passion was

129
00:05:30,129 --> 00:05:31,564
baseball.

130
00:05:31,564 --> 00:05:33,966
I was a pitcher, and so one of

131
00:05:33,966 --> 00:05:35,668
the things I did when I got to

132
00:05:35,668 --> 00:05:38,171
the air force academy was walk

133
00:05:38,171 --> 00:05:40,373
onto the baseball team.

134
00:05:40,373 --> 00:05:41,641
I played for a couple of years

135
00:05:41,641 --> 00:05:43,242
there on the junior varsity

136
00:05:43,242 --> 00:05:45,378
team, and then got a chance to

137
00:05:45,378 --> 00:05:48,147
throw an inning at the varsity

138
00:05:48,147 --> 00:05:49,682
level, and then after that they

139
00:05:49,682 --> 00:05:51,818
decided that my hobby was going

140
00:05:51,818 --> 00:05:55,221
to go anywhere, and I got cut.

141
00:05:55,221 --> 00:05:56,823
So everybody has their

142
00:05:56,823 --> 00:05:58,825
individual tastes.

143
00:05:58,825 --> 00:06:01,094
When it comes to food, it's

144
00:06:01,094 --> 00:06:03,229
peanut butter and chocolate for

145
00:06:03,229 --> 00:06:03,796
me.

146
00:06:03,796 --> 00:06:05,064
That's an addiction I have.

147
00:06:05,064 --> 00:06:10,069
Who doesn't love a bowl of

148
00:06:10,069 --> 00:06:12,205
peanut butter and chocolate ice

149
00:06:12,205 --> 00:06:13,272
cream.

150
00:06:13,272 --> 00:06:15,174
The other thing that I enjoy is

151
00:06:15,174 --> 00:06:17,243
crushed red pepper garlic.

152
00:06:17,243 --> 00:06:19,445
If you put garlic on anything,

153
00:06:19,445 --> 00:06:21,581
it makes it taste better.

154
00:06:21,581 --> 00:06:23,416
So those are the things I crave

155
00:06:23,416 --> 00:06:33,559
when it comes to food.

156
00:06:33,559 --> 00:06:39,532
>> NASA's artimiss is working to

157
00:06:39,532 --> 00:06:41,367
returning to the moon and the

158
00:06:41,367 --> 00:06:44,937
surface of mars.

159
00:06:44,937 --> 00:06:46,639
Those are both missions that

160
00:06:46,639 --> 00:06:53,146
will deal with issues of

161
00:06:53,146 --> 00:06:55,848
creating materials for the crew.

162
00:06:55,848 --> 00:07:00,920
Mining may allow them to find

163
00:07:00,920 --> 00:07:02,355
the materials they need rather

164
00:07:02,355 --> 00:07:04,357
than bringing them from earth.

165
00:07:04,357 --> 00:07:08,628
But there is a new investigation

166
00:07:08,628 --> 00:07:10,196
on the international space

167
00:07:10,196 --> 00:07:12,498
station studying how microbes

168
00:07:12,498 --> 00:07:15,034
grow on and how they alter

169
00:07:15,034 --> 00:07:17,370
planetary rocks in micro gravity

170
00:07:17,370 --> 00:07:21,140
and simulated martian gravity.

171
00:07:21,140 --> 00:07:24,143
>> The international space

172
00:07:24,143 --> 00:07:26,012
station will soon host some of

173
00:07:26,012 --> 00:07:29,148
the smallest miners in the

174
00:07:29,148 --> 00:07:31,417
universe: microbes.

175
00:07:31,417 --> 00:07:34,821
Microbes growing on the surface

176
00:07:34,821 --> 00:07:37,123
of rocks can break them down and

177
00:07:37,123 --> 00:07:41,093
extract useful metals.

178
00:07:41,093 --> 00:07:44,664
Er this is a process called bio

179
00:07:44,664 --> 00:07:45,531
mining.

180
00:07:45,531 --> 00:07:47,133
We're looking to turn rock into

181
00:07:47,133 --> 00:07:49,001
soil for growing plants and

182
00:07:49,001 --> 00:07:49,869
food.

183
00:07:49,869 --> 00:07:50,736
But before we can use this

184
00:07:50,736 --> 00:07:52,705
technique in planetary

185
00:07:52,705 --> 00:07:54,407
settlements, we first need to

186
00:07:54,407 --> 00:07:55,274
test it in space.

187
00:07:55,274 --> 00:08:03,349
On the space station bio

188
00:08:03,349 --> 00:08:06,219
reactors will be placed inside

189
00:08:06,219 --> 00:08:13,759
of enter--centrifuge.

190
00:08:13,759 --> 00:08:16,195
Investigators will exam how

191
00:08:16,195 --> 00:08:18,898
three types of microbes behave

192
00:08:18,898 --> 00:08:20,900
within pieces of the salt, and

193
00:08:20,900 --> 00:08:22,168
evaluate how well the different

194
00:08:22,168 --> 00:08:24,470
microbes extract elements from

195
00:08:24,470 --> 00:08:24,871
the rock.

196
00:08:24,871 --> 00:08:30,142
The findings will be compared to

197
00:08:30,142 --> 00:08:31,711
ground based results.

198
00:08:31,711 --> 00:08:38,384
We hope to gain insights into

199
00:08:38,384 --> 00:08:41,254
how microbes interact with rocks

200
00:08:41,254 --> 00:08:43,322
and micro gravity, and how we

201
00:08:43,322 --> 00:08:45,124
might use them in our

202
00:08:45,124 --> 00:08:55,268
exploration of deep space.

203
00:08:55,268 --> 00:08:57,103
>> Robotic technology originally

204
00:08:57,103 --> 00:08:58,404
designed for the international

205
00:08:58,404 --> 00:09:00,106
space station has found a new

206
00:09:00,106 --> 00:09:01,941
application in healthcare as

207
00:09:01,941 --> 00:09:04,410
part of a telerobottic

208
00:09:04,410 --> 00:09:06,812
technology to provide mri-guided

209
00:09:06,812 --> 00:09:08,948
best buy oncies to women in

210
00:09:08,948 --> 00:09:11,217
remote areas.

211
00:09:11,217 --> 00:09:12,652
The Canadian space agency

212
00:09:12,652 --> 00:09:14,320
contributed to the production of

213
00:09:14,320 --> 00:09:15,354
this feature about the

214
00:09:15,354 --> 00:09:21,327
innovations coming for

215
00:09:21,327 --> 00:09:23,162
innovation from Hamilton,

216
00:09:23,162 --> 00:09:26,032
Ontario.

217
00:09:26,032 --> 00:09:34,273
>> Space exploration means

218
00:09:34,273 --> 00:09:39,111
exposure to harsh environments.

219
00:09:39,111 --> 00:09:40,680
The other issue that now they're

220
00:09:40,680 --> 00:09:42,248
spending time to do the

221
00:09:42,248 --> 00:09:43,950
maintenance work and they're not

222
00:09:43,950 --> 00:09:45,117
doing the science, which is

223
00:09:45,117 --> 00:09:46,385
really what their purpose is.

224
00:09:46,385 --> 00:09:49,255
So with the maintenance

225
00:09:49,255 --> 00:09:50,523
challenges that we're going to

226
00:09:50,523 --> 00:09:51,490
have with the international

227
00:09:51,490 --> 00:09:53,059
space station, what we found is

228
00:09:53,059 --> 00:09:54,894
can it be in position to provide

229
00:09:54,894 --> 00:09:57,263
a solution to that problem?

230
00:09:57,263 --> 00:09:58,464
And Dexter was going to be that

231
00:09:58,464 --> 00:09:59,131
solution.

232
00:09:59,131 --> 00:10:01,901
Dexter is a two-armed robotic

233
00:10:01,901 --> 00:10:04,603
manipulator system capable of

234
00:10:04,603 --> 00:10:07,306
performing fine-motor tasks to

235
00:10:07,306 --> 00:10:09,041
replace what the astronaut would

236
00:10:09,041 --> 00:10:10,810
have to do on the exterior of

237
00:10:10,810 --> 00:10:12,078
the space station.

238
00:10:12,078 --> 00:10:15,147
I is basically a handyman.

239
00:10:15,147 --> 00:10:16,983
He allows us to do space

240
00:10:16,983 --> 00:10:17,850
maintenance.

241
00:10:17,850 --> 00:10:19,118
We're able to control it from

242
00:10:19,118 --> 00:10:19,852
the ground.

243
00:10:19,852 --> 00:10:21,687
So the ground crew could "K"

244
00:10:21,687 --> 00:10:23,255
operate these robotic systems

245
00:10:23,255 --> 00:10:26,125
and free the astronauts up from

246
00:10:26,125 --> 00:10:27,493
that task as well.

247
00:10:27,493 --> 00:10:29,228
Now that they're operating on a

248
00:10:29,228 --> 00:10:31,364
regular basis, we have a crew

249
00:10:31,364 --> 00:10:34,800
spending more time doing

250
00:10:34,800 --> 00:10:35,334
science.

251
00:10:35,334 --> 00:10:37,636
This was the idea of building an

252
00:10:37,636 --> 00:10:39,472
international space station, to

253
00:10:39,472 --> 00:10:41,774
be able to do science in lower

254
00:10:41,774 --> 00:10:53,619
earth orbit.

255
00:10:53,619 --> 00:10:55,755
>> Only 40% of women are getting

256
00:10:55,755 --> 00:10:57,923
annual mri as part of their

257
00:10:57,923 --> 00:10:59,492
screening.

258
00:10:59,492 --> 00:11:06,032
Part of the reason providing mri

259
00:11:06,032 --> 00:11:08,467
screening was because of lack of

260
00:11:08,467 --> 00:11:11,003
access to the radiologists.

261
00:11:11,003 --> 00:11:13,172
>> Some women have to drive very

262
00:11:13,172 --> 00:11:15,708
long distances, like seven or

263
00:11:15,708 --> 00:11:19,845
eight hours in the car,

264
00:11:19,845 --> 00:11:21,914
sometimes during snowstorms in

265
00:11:21,914 --> 00:11:23,816
the winter, so they may risk

266
00:11:23,816 --> 00:11:27,953
their lives to get the mris.

267
00:11:27,953 --> 00:11:30,089
>> When we started to do the

268
00:11:30,089 --> 00:11:35,361
research, we started to get

269
00:11:35,361 --> 00:11:38,330
involved with mda.

270
00:11:38,330 --> 00:11:40,066
A company that has been involved

271
00:11:40,066 --> 00:11:41,634
with manufacturing of all of the

272
00:11:41,634 --> 00:11:43,335
robotic systems, which is

273
00:11:43,335 --> 00:11:44,737
currently used on the space

274
00:11:44,737 --> 00:11:45,304
station.

275
00:11:45,304 --> 00:11:47,940
>> We developed a system called

276
00:11:47,940 --> 00:11:50,076
igr which stands for

277
00:11:50,076 --> 00:11:53,512
image-guided robot.

278
00:11:53,512 --> 00:11:57,483
>> Igar is an operated robot

279
00:11:57,483 --> 00:12:12,865
that that perform breast

280
00:12:12,865 --> 00:12:14,867
biopsies.

281
00:12:14,867 --> 00:12:16,569
>> It is provided to patients

282
00:12:16,569 --> 00:12:18,270
who may be thousands of

283
00:12:18,270 --> 00:12:20,406
kilometerses away.

284
00:12:20,406 --> 00:12:24,677
The patients can go under breast

285
00:12:24,677 --> 00:12:29,115
biopsy at their local hotel

286
00:12:29,115 --> 00:12:30,649
without having to travel to

287
00:12:30,649 --> 00:12:31,817
another hospital for the

288
00:12:31,817 --> 00:12:32,785
expertise.

289
00:12:32,785 --> 00:12:33,652
>> The results have been

290
00:12:33,652 --> 00:12:34,787
encouraging.

291
00:12:34,787 --> 00:12:37,089
We've demonstrated that it is

292
00:12:37,089 --> 00:12:39,625
safe, extremely accurate, as

293
00:12:39,625 --> 00:12:40,793
accurate as a human.

294
00:12:40,793 --> 00:12:42,328
>> This will allow us to

295
00:12:42,328 --> 00:12:43,896
hopefully increase the number of

296
00:12:43,896 --> 00:12:45,898
people undergoing screening

297
00:12:45,898 --> 00:12:48,634
close to 100% ratio.

298
00:12:48,634 --> 00:12:51,937
So igar is built on many of the

299
00:12:51,937 --> 00:12:54,773
know how which was developed for

300
00:12:54,773 --> 00:12:56,509
the space program as well as the

301
00:12:56,509 --> 00:12:58,644
software which is also used to

302
00:12:58,644 --> 00:13:00,646
control the robotics of the

303
00:13:00,646 --> 00:13:01,213
space station.

304
00:13:01,213 --> 00:13:02,348
>> We can see some of these

305
00:13:02,348 --> 00:13:03,616
technologies that we've worked

306
00:13:03,616 --> 00:13:05,351
with for a long time becoming

307
00:13:05,351 --> 00:13:06,752
available.

308
00:13:06,752 --> 00:13:07,987
We have a lot of insight of how

309
00:13:07,987 --> 00:13:09,855
to apply them.

310
00:13:09,855 --> 00:13:11,257
Not just in medicine, but in a

311
00:13:11,257 --> 00:13:12,892
number of other fields, which is

312
00:13:12,892 --> 00:13:14,093
what we're doing.

313
00:13:14,093 --> 00:13:15,594
Without the space station, would

314
00:13:15,594 --> 00:13:17,530
any of that have happened?

315
00:13:17,530 --> 00:13:18,864
No, not really.

316
00:13:18,864 --> 00:13:38,784
Not in that way, any way.

317
00:13:38,784 --> 00:13:40,920
>> Whether you're in space or

318
00:13:40,920 --> 00:13:44,323
here on earth, we always have

319
00:13:44,323 --> 00:13:46,458
trillions of micro organisms

320
00:13:46,458 --> 00:13:48,227
that live on or inside our

321
00:13:48,227 --> 00:13:48,961
bodies.

322
00:13:48,961 --> 00:13:51,397
They outnumber our cells 5-1,

323
00:13:51,397 --> 00:13:52,831
but many of them are essential

324
00:13:52,831 --> 00:13:54,233
to human health.

325
00:13:54,233 --> 00:13:55,367
Because of that, there is one

326
00:13:55,367 --> 00:13:56,635
study on the international space

327
00:13:56,635 --> 00:13:58,771
station looking into how space

328
00:13:58,771 --> 00:14:00,639
flight can change those micro

329
00:14:00,639 --> 00:14:02,775
organisms, and what that could

330
00:14:02,775 --> 00:14:04,910
mean for our bodies internal

331
00:14:04,910 --> 00:15:38,804
systems.

332
00:15:38,804 --> 00:15:40,773
>> Up there in orbit during long

333
00:15:40,773 --> 00:15:43,208
duration space flights, the

334
00:15:43,208 --> 00:15:44,510
astronautS can experience

335
00:15:44,510 --> 00:15:45,778
structural changes to their

336
00:15:45,778 --> 00:15:47,112
hearts, but exactly what

337
00:15:47,112 --> 00:15:48,714
changes, and how they occur are

338
00:15:48,714 --> 00:15:51,250
not yet clearly understood.

339
00:15:51,250 --> 00:15:52,117
That's why researchers are

340
00:15:52,117 --> 00:15:55,220
investigating cardiovascular

341
00:15:55,220 --> 00:15:56,822
stem cells so they can better

342
00:15:56,822 --> 00:15:58,957
understand the roles those cells

343
00:15:58,957 --> 00:16:00,626
play in the make up of our heart

344
00:16:00,626 --> 00:16:01,360
as well as in tissue

345
00:16:01,360 --> 00:16:34,827
regeneration.

346
00:16:34,827 --> 00:16:36,962
>> We know that they are an

347
00:16:36,962 --> 00:16:39,498
early population of cells.

348
00:16:39,498 --> 00:16:41,633
We're able to create different

349
00:16:41,633 --> 00:16:43,635
types of cardiac tissue whether

350
00:16:43,635 --> 00:16:46,572
it be the heart muscle cells, or

351
00:16:46,572 --> 00:16:50,676
the lining of blood vessels.

352
00:16:50,676 --> 00:16:51,977
The cells we work with have the

353
00:16:51,977 --> 00:16:55,114
capacity of bombing

354
00:16:55,114 --> 00:16:58,217
cardiovascular derivatives, and

355
00:16:58,217 --> 00:17:01,387
they function in a way in the

356
00:17:01,387 --> 00:17:02,821
environment and there is a lot

357
00:17:02,821 --> 00:17:04,790
we can learn in the treatment.

358
00:17:04,790 --> 00:17:10,763
Studying the cardiovascular

359
00:17:10,763 --> 00:17:11,764
tissue, and looking at

360
00:17:11,764 --> 00:17:14,767
disparities in their response,

361
00:17:14,767 --> 00:17:20,739
neonatal versus adult patients.

362
00:17:20,739 --> 00:17:23,275
We're able to compare the micro

363
00:17:23,275 --> 00:17:26,278
gravity using the same clone and

364
00:17:26,278 --> 00:17:28,113
be able to compare these two

365
00:17:28,113 --> 00:17:30,015
results to see if we can use the

366
00:17:30,015 --> 00:17:32,951
micro gravity, or any type of

367
00:17:32,951 --> 00:17:34,853
micro gravity treatment to

368
00:17:34,853 --> 00:17:37,689
promote cardiovascular care.

369
00:17:37,689 --> 00:17:39,224
We've been learning quite a bit

370
00:17:39,224 --> 00:17:40,759
even from the simulation, and we

371
00:17:40,759 --> 00:17:42,361
think with this space flight

372
00:17:42,361 --> 00:17:43,796
will be able to extend these

373
00:17:43,796 --> 00:17:45,631
observations, and hopefully

374
00:17:45,631 --> 00:17:50,402
promote cardiac repair.

375
00:17:50,402 --> 00:17:52,404
And even advance these insights

376
00:17:52,404 --> 00:17:55,941
in anticipating and treating in

377
00:17:55,941 --> 00:18:01,246
space.

378
00:18:01,246 --> 00:18:02,548
>> For many experiments where

379
00:18:02,548 --> 00:18:06,084
the astronautS and cosmonauts

380
00:18:06,084 --> 00:18:08,086
are test subjects there are

381
00:18:08,086 --> 00:18:09,755
samples that need to be produced

382
00:18:09,755 --> 00:18:11,323
and stored in space before they

383
00:18:11,323 --> 00:18:13,325
are returned to earth for study.

384
00:18:13,325 --> 00:18:15,427
Where do they store these test

385
00:18:15,427 --> 00:18:16,328
results?

386
00:18:16,328 --> 00:18:18,163
Well, in one of a dozen large

387
00:18:18,163 --> 00:18:20,866
freezers, in the speedy time

388
00:18:20,866 --> 00:18:24,036
segment, Jack fischer signs the

389
00:18:24,036 --> 00:18:26,572
light on the lab tear freezer

390
00:18:26,572 --> 00:18:27,840
for iss.

391
00:18:27,840 --> 00:18:29,441
>> Hello and welcome to another

392
00:18:29,441 --> 00:18:30,709
speedy time.

393
00:18:30,709 --> 00:18:31,844
Today we're going to talk about

394
00:18:31,844 --> 00:18:33,979
one of the most useful tools we

395
00:18:33,979 --> 00:18:35,547
have on the space station, the

396
00:18:35,547 --> 00:18:38,083
minus 80 lab freezer iss.

397
00:18:38,083 --> 00:18:42,221
Or as I like to call it, the

398
00:18:42,221 --> 00:18:44,656
freezer of awesomeness.

399
00:18:44,656 --> 00:18:46,091
We want to get all of these

400
00:18:46,091 --> 00:18:48,427
samples we take on the ground.

401
00:18:48,427 --> 00:18:49,428
In order to do that, we need a

402
00:18:49,428 --> 00:18:50,295
freezer.

403
00:18:50,295 --> 00:18:58,103
To get these freezers down below

404
00:18:58,103 --> 00:19:02,941
185, this is the big daddy.

405
00:19:02,941 --> 00:19:04,376
We have to wear these special

406
00:19:04,376 --> 00:19:04,676
gloves.

407
00:19:04,676 --> 00:19:09,515
Do you remember the Christmas

408
00:19:09,515 --> 00:19:14,620
story where he stuck his tongue?

409
00:19:14,620 --> 00:19:16,188
That's the same idea.

410
00:19:16,188 --> 00:19:17,923
We put these in these super

411
00:19:17,923 --> 00:19:19,591
coolers and then all of the

412
00:19:19,591 --> 00:19:21,326
science can be studied, and

413
00:19:21,326 --> 00:19:22,995
hopefully we find the cool

414
00:19:22,995 --> 00:19:25,130
results out of our experiment.

415
00:19:25,130 --> 00:19:48,220
I have an sample.

416
00:19:48,220 --> 00:19:49,488
>> That, my friend is the

417
00:19:49,488 --> 00:19:52,457
awesome super freezer that we

418
00:19:52,457 --> 00:19:54,626
have on the space station.

419
00:19:54,626 --> 00:19:56,228
Hope you learned something, have

420
00:19:56,228 --> 00:19:57,329
a great day.

421
00:19:57,329 --> 00:19:58,597
>> Scientists are using the

422
00:19:58,597 --> 00:19:59,865
international space station to

423
00:19:59,865 --> 00:20:01,466
learn more about the physical

424
00:20:01,466 --> 00:20:02,734
sciences, too.

425
00:20:02,734 --> 00:20:06,138
Researchers behind a number of

426
00:20:06,138 --> 00:20:10,976
experiments on the science of

427
00:20:10,976 --> 00:20:15,981
comebustion hope to learn ways

428
00:20:15,981 --> 00:20:18,050
to create less pollution.

429
00:20:18,050 --> 00:20:19,851
>> The power of studying

430
00:20:19,851 --> 00:20:23,956
combustion on the iss presented

431
00:20:23,956 --> 00:20:29,027
by science at NASA.

432
00:20:29,027 --> 00:20:30,362
If you want to reduce the amount

433
00:20:30,362 --> 00:20:33,365
of pollution humans produce,

434
00:20:33,365 --> 00:20:35,500
where might you look?

435
00:20:35,500 --> 00:20:38,036
Here, yep, here?

436
00:20:38,036 --> 00:20:38,737
Sure.

437
00:20:38,737 --> 00:20:39,471
Here?

438
00:20:39,471 --> 00:20:41,607
Wait, what?

439
00:20:41,607 --> 00:20:45,010
That's exactly where scientists

440
00:20:45,010 --> 00:20:46,745
and researchers are looking,

441
00:20:46,745 --> 00:20:50,082
255 miles above earth on the

442
00:20:50,082 --> 00:20:51,783
international space station.

443
00:20:51,783 --> 00:20:52,651
Here astronautS are working on a

444
00:20:52,651 --> 00:20:54,620
series of experiments to learn

445
00:20:54,620 --> 00:20:58,890
more about combustion.

446
00:20:58,890 --> 00:21:03,895
Why combustion, the experiments,

447
00:21:03,895 --> 00:21:06,298
they say consider this, 85% of

448
00:21:06,298 --> 00:21:08,300
the energy we use comes from

449
00:21:08,300 --> 00:21:11,136
combustion.

450
00:21:11,136 --> 00:21:13,271
The burning of some sort of

451
00:21:13,271 --> 00:21:14,539
fuel.

452
00:21:14,539 --> 00:21:16,975
85% of the electricity that we

453
00:21:16,975 --> 00:21:19,378
use at home and work come from

454
00:21:19,378 --> 00:21:21,513
power plants that use

455
00:21:21,513 --> 00:21:24,216
combustion.

456
00:21:24,216 --> 00:21:25,384
If we can learn more about the

457
00:21:25,384 --> 00:21:27,386
process, we might be able to

458
00:21:27,386 --> 00:21:30,088
find newer and less polluting

459
00:21:30,088 --> 00:21:32,090
ways to burn fuel.

460
00:21:32,090 --> 00:21:35,494
Three series of combustion

461
00:21:35,494 --> 00:21:38,730
experiments on the cir are

462
00:21:38,730 --> 00:21:42,300
looking at combustion in very

463
00:21:42,300 --> 00:21:43,168
different ways.

464
00:21:43,168 --> 00:21:48,807
The flame extinguish experiment

465
00:21:48,807 --> 00:21:52,077
or flex, the last of the droplet

466
00:21:52,077 --> 00:21:55,247
combustion experiments were

467
00:21:55,247 --> 00:22:06,758
conducted in September 2017.

468
00:22:06,758 --> 00:22:07,392
These entrepreneurial possesses

469
00:22:07,392 --> 00:22:09,294
will exam how various gasses

470
00:22:09,294 --> 00:22:11,029
burn without gravity affecting

471
00:22:11,029 --> 00:22:12,864
the flames.

472
00:22:12,864 --> 00:22:14,833
The solid fuel ignition and

473
00:22:14,833 --> 00:22:20,372
extinction will explore the

474
00:22:20,372 --> 00:22:23,241
properties of burning solid

475
00:22:23,241 --> 00:22:24,509
matter.

476
00:22:24,509 --> 00:22:26,978
Why study in micro gravity?

477
00:22:26,978 --> 00:22:31,249
In the iss you have conditions

478
00:22:31,249 --> 00:22:36,888
that can't be found on earth.

479
00:22:36,888 --> 00:22:39,057
The candle flickers, why?

480
00:22:39,057 --> 00:22:41,326
Because the air cause it is to

481
00:22:41,326 --> 00:22:42,194
rise.

482
00:22:42,194 --> 00:22:44,196
This occurs at high speeds and

483
00:22:44,196 --> 00:22:46,164
resulting in turbulence and

484
00:22:46,164 --> 00:22:46,965
instability.

485
00:22:46,965 --> 00:22:48,800
That makes it hard to study the

486
00:22:48,800 --> 00:22:50,235
properties of the flame.

487
00:22:50,235 --> 00:22:52,370
But on the iss there is no

488
00:22:52,370 --> 00:22:54,906
flicker, which allows us to make

489
00:22:54,906 --> 00:22:57,609
more precise and consistent

490
00:22:57,609 --> 00:22:58,643
measurements.

491
00:22:58,643 --> 00:23:01,480
If we have precise measurements,

492
00:23:01,480 --> 00:23:03,315
we get closer to burning more

493
00:23:03,315 --> 00:23:04,349
efficiently.

494
00:23:04,349 --> 00:23:06,184
And more efficiency produce cost

495
00:23:06,184 --> 00:23:08,320
savings in producing power and

496
00:23:08,320 --> 00:23:12,457
reducing the production of soot

497
00:23:12,457 --> 00:23:16,995
and other pollutants.

498
00:23:16,995 --> 00:23:19,998
It brings practical applications

499
00:23:19,998 --> 00:23:20,699
on earth.

500
00:23:20,699 --> 00:23:22,968
A new type of fire extinguisher

501
00:23:22,968 --> 00:23:25,837
is only one example, and I think

502
00:23:25,837 --> 00:23:28,540
we're in for a new surprises as

503
00:23:28,540 --> 00:23:32,377
a result of these micro gravity

504
00:23:32,377 --> 00:23:33,645
experiments.

505
00:23:33,645 --> 00:23:34,646
Because they knew where to look

506
00:23:34,646 --> 00:23:37,182
for answers in reducing global

507
00:23:37,182 --> 00:23:38,083
pollution.

508

>> Engineers who are developing

515
00:23:59,638 --> 00:24:02,340
the future spaceships are able

516
00:24:02,340 --> 00:24:08,146
to work out their issues with

517
00:24:08,146 --> 00:24:09,581
human needs in orbit.

518
00:24:09,581 --> 00:24:13,451
Issues like providing clean

519
00:24:13,451 --> 00:24:14,019
water.

520
00:24:14,019 --> 00:24:16,321
In this video series, they

521
00:24:16,321 --> 00:24:17,856
discuss the water recovery

522
00:24:17,856 --> 00:24:19,724
system used to recycle crew

523
00:24:19,724 --> 00:24:42,914
waste water for consumption.

524
00:24:42,914 --> 00:24:45,617
>> Hi welcome to the

525
00:24:45,617 --> 00:24:46,618
international space station.

526
00:24:46,618 --> 00:24:49,821
On our water recovery system is

527
00:24:49,821 --> 00:24:51,223
vital to our mission and

528
00:24:51,223 --> 00:24:52,057
survival.

529
00:24:52,057 --> 00:24:56,228
You want to know why and how we

530
00:24:56,228 --> 00:24:58,230
recycle our water?

531
00:24:58,230 --> 00:24:59,497
Let's go.

532
00:24:59,497 --> 00:25:02,500
We use water recovery filtration

533
00:25:02,500 --> 00:25:04,469
because it is expensive to

534
00:25:04,469 --> 00:25:07,339
provide on missions.

535
00:25:07,339 --> 00:25:09,474
Think about the weight of a

536
00:25:09,474 --> 00:25:11,309
single bucket of water.

537
00:25:11,309 --> 00:25:13,178
With you imagine the weight of

538
00:25:13,178 --> 00:25:16,848
water for moss' supply on for

539
00:25:16,848 --> 00:25:18,283
several people on the enter

540
00:25:18,283 --> 00:25:21,853
space station?

541
00:25:21,853 --> 00:25:23,121
That's a lot of water, and

542
00:25:23,121 --> 00:25:25,257
bringing it with us is not very

543
00:25:25,257 --> 00:25:26,258
efficient.

544
00:25:26,258 --> 00:25:28,660
On station we recycle space

545
00:25:28,660 --> 00:25:30,795
water to get fresh drinking

546
00:25:30,795 --> 00:25:31,663
water.

547
00:25:31,663 --> 00:25:33,665
This includes our urine,

548
00:25:33,665 --> 00:25:36,801
moisture, exhale, and sweat.

549
00:25:36,801 --> 00:25:38,069
Along with the water we use to

550
00:25:38,069 --> 00:25:39,504
bathe and shave.

551
00:25:39,504 --> 00:25:40,739
It works like this.

552
00:25:40,739 --> 00:25:43,642
When we use the both, urine is

553
00:25:43,642 --> 00:25:48,947
collected, and the touches spin,

554
00:25:48,947 --> 00:25:50,682
urine is heated to evaporate

555
00:25:50,682 --> 00:25:51,950
water from the waste, and thin

556
00:25:51,950 --> 00:25:54,085
condensed in the outer chambers

557
00:25:54,085 --> 00:25:56,788
to form.

558
00:25:56,788 --> 00:25:58,056
Next the water is pumped to a

559
00:25:58,056 --> 00:25:59,958
tank where it is joined with the

560
00:25:59,958 --> 00:26:03,061
water recovered from cabin air

561
00:26:03,061 --> 00:26:07,198
created by crew sweat and

562
00:26:07,198 --> 00:26:09,167
respiration.

563
00:26:09,167 --> 00:26:13,438
Contaminates are removed with

564
00:26:13,438 --> 00:26:17,008
heat, and then iodine is added.

565
00:26:17,008 --> 00:26:19,010
It is monitored for bacteria,

566
00:26:19,010 --> 00:26:22,147
pollutants and proper ph.

567
00:26:22,147 --> 00:26:25,250
The ph scale ranges from 0 to

568
00:26:25,250 --> 00:26:30,121
14, and it is a tool used by

569
00:26:30,121 --> 00:26:35,493
scientists to measure for acid

570
00:26:35,493 --> 00:26:36,528
to base.

571
00:26:36,528 --> 00:26:38,196
The process provides clean

572
00:26:38,196 --> 00:26:40,465
drinking water that we get to

573
00:26:40,465 --> 00:26:41,533
enjoy every day.

574
00:26:41,533 --> 00:26:43,201
The recycled water on the space

575
00:26:43,201 --> 00:26:46,604
station is sterile.

576
00:26:46,604 --> 00:26:49,975
There is no odor or bad taste.

577
00:26:49,975 --> 00:26:50,976
Water is critical, and it will

578
00:26:50,976 --> 00:26:53,111
be for future trips to the moon

579
