00:00:20,240 --> 00:00:17,730
Hangout exploring the space station and

6
00:00:21,950 --> 00:00:20,250
spacewalks and science on orbit this

7
00:00:23,750 --> 00:00:21,960
event connects NASA social media

8
00:00:25,700 --> 00:00:23,760
followers with astronauts were on the

9
00:00:26,810 --> 00:00:25,710
ground the recently returned from living

10
00:00:29,390 --> 00:00:26,820
and working aboard the space station

11
00:00:32,290 --> 00:00:29,400
orbiting some 230 miles above the earth

12
00:00:34,880 --> 00:00:32,300
and traveling at 17,500 miles per hour

13
00:00:38,090 --> 00:00:34,890
will be taking real-time questions using

14
00:00:40,760 --> 00:00:38,100
the hashtag pound ask Astro excuse me

15
00:00:43,400 --> 00:00:40,770
pound ask NASA on Twitter or from the

16
00:00:44,840 --> 00:00:43,410
NASA Google+ page during the event we've

17
00:00:46,310 --> 00:00:44,850
also opened up a comment thread on

18
00:00:48,650 --> 00:00:46,320
NASA's Facebook page where you can post

19
00:00:50,479 --> 00:00:48,660
questions let me introduce those who are

20
00:00:52,459 --> 00:00:50,489
joining us on today's hangout we have

21
00:00:55,970 --> 00:00:52,469
with us nasa astronaut suni williams and

22
00:00:58,279 --> 00:00:55,980
japanese astronaut aki hoshide both

23
00:01:02,060 --> 00:00:58,289
sunny and aki recently returned to Earth

24
00:01:04,460 --> 00:01:02,070
on November 18 2012 after spending 127

25
00:01:06,050 --> 00:01:04,470
days in space including 125 of those

26
00:01:08,510 --> 00:01:06,060
aboard the International Space Station

27
00:01:10,550 --> 00:01:08,520
we're also joined by two NASA Explorer

28
00:01:12,380 --> 00:01:10,560
schools on today's hangout we have with

29
00:01:13,850 --> 00:01:12,390
us high school science students from

30
00:01:18,559 --> 00:01:13,860
Dalton Intermediate School in Dalton

31
00:01:20,150 --> 00:01:18,569
Ohio wave guys hi we also have with us

32
00:01:22,070 --> 00:01:20,160
middle school science students from Our

33
00:01:25,779 --> 00:01:22,080
Lady of Perpetual Help Catholic School

34
00:01:30,949 --> 00:01:29,270
hi guys at this point I want to

35
00:01:32,300 --> 00:01:30,959
introduce to you guys our astronauts

36
00:01:33,559 --> 00:01:32,310
here they're gonna talk a little bit

37
00:01:36,620 --> 00:01:33,569
about their mission and we have a little

38
00:01:38,270 --> 00:01:36,630
video for you guys so take it away hi

39
00:01:41,080 --> 00:01:38,280
everybody we were psyched to be here

40
00:01:47,540 --> 00:01:45,139
so Aki and I like Jason said just got

41
00:01:49,729 --> 00:01:47,550
back from space in November so we've

42
00:01:52,249 --> 00:01:49,739
gone through a little physical rehab and

43
00:01:53,839 --> 00:01:52,259
now are raring to go to get ready to

44
00:01:56,300 --> 00:01:53,849
talk to you guys about what we did up in

45
00:01:59,240 --> 00:01:56,310
space so to start that we got a little

46
00:02:01,820 --> 00:01:59,250
video that shows some of the things that

47
00:02:03,979 --> 00:02:01,830
we did while we are up there it's gonna

48
00:02:06,650 --> 00:02:03,989
start off with a couple different crews

49
00:02:10,609 --> 00:02:06,660
of six because we'd be on a swimming

50
00:02:12,830 --> 00:02:10,619
spacecraft Soyuz have crews of three so

51
00:02:15,140 --> 00:02:12,840
there's two show use docked to the space

52
00:02:16,880 --> 00:02:15,150
station which means three plus three is

53
00:02:18,110 --> 00:02:16,890
six so six people are living on the

54
00:02:20,750 --> 00:02:18,120
space station

55
00:02:23,150 --> 00:02:20,760
now four Soyuz fly per year - in the

56
00:02:24,890 --> 00:02:23,160
spring and - in the fall so we alternate

57
00:02:26,449 --> 00:02:24,900
cruise back and forth and that's why

58
00:02:28,640 --> 00:02:26,459
you'll see different people in the

59
00:02:30,770 --> 00:02:28,650
pictures part of the video also shows

60
00:02:32,300 --> 00:02:30,780
our training strength training is pretty

61
00:02:34,070 --> 00:02:32,310
extensive it's about two and a half

62
00:02:37,280 --> 00:02:34,080
years of training not only here in the

63
00:02:40,820 --> 00:02:37,290
US but also of course in Japan in Russia

64
00:02:43,039 --> 00:02:40,830
in Canada and Europe and so we do a lot

65
00:02:45,890 --> 00:02:43,049
of traveling to support getting ready

66
00:02:47,660 --> 00:02:45,900
for this or our flight in space on the

67
00:02:49,130 --> 00:02:47,670
space station some of the things we're

68
00:02:52,160 --> 00:02:49,140
gonna do while we're up there is

69
00:02:54,259 --> 00:02:52,170
spacewalks and also some work with a

70
00:02:56,420 --> 00:02:54,269
robotic arm as well as lots and lots and

71
00:02:59,150 --> 00:02:56,430
lots of science experiments so in the

72
00:03:00,410 --> 00:02:59,160
video you're going to see some of the

73
00:03:02,539 --> 00:03:00,420
science experiments some of the stuff we

74
00:03:06,050 --> 00:03:02,549
do to ourselves take our blood take our

75
00:03:10,280 --> 00:03:06,060
urine look at our eyes for example

76
00:03:11,780 --> 00:03:10,290
you're gonna see what space walk what it

77
00:03:14,030 --> 00:03:11,790
looks like to be in a spacesuit and go

78
00:03:17,000 --> 00:03:14,040
on a spacewalk and you're also gonna see

79
00:03:19,520 --> 00:03:17,010
some of what we call visiting vehicles

80
00:03:20,960 --> 00:03:19,530
that come to the station for only a

81
00:03:23,479 --> 00:03:20,970
small amount of time but they're the

82
00:03:24,770 --> 00:03:23,489
ones who bring supplies food water

83
00:03:26,780 --> 00:03:24,780
clothes

84
00:03:29,690 --> 00:03:26,790
toothbrushes new experiments and even

85
00:03:32,690 --> 00:03:29,700
spiders sometimes so you'll see all of

86
00:03:35,089 --> 00:03:32,700
those spacecraft up there and then

87
00:03:38,599 --> 00:03:35,099
you're gonna see how we come back from

88
00:03:41,780 --> 00:03:38,609
space now you know we launch and come

89
00:03:44,180 --> 00:03:41,790
back from space in Kazakhstan and that's

90
00:03:47,569 --> 00:03:44,190
a country if you're familiar with it a

91
00:03:50,330 --> 00:03:47,579
little bit in the middle of the Asian

92
00:03:51,589 --> 00:03:50,340
continent just south of Russia and so

93
00:03:52,879 --> 00:03:51,599
you'll be able to see what a little bit

94
00:03:55,460 --> 00:03:52,889
of that looks like and you'll be able to

95
00:03:55,970 --> 00:03:55,470
see our Soyuz capsule from where we

96
00:03:58,309 --> 00:03:55,980
landed

97
00:03:59,720 --> 00:03:58,319
so with that Aki and I would like to

98
00:04:02,509 --> 00:03:59,730
show you the video and then we'll be

99
00:06:56,380 --> 00:04:02,519
ready for some questions - whatever you

100
00:07:03,050 --> 00:07:00,350
liftoff of the soyuz tma-05m carrying

101
00:07:04,760 --> 00:07:03,060
sunday williams yuri malenchenko and aki

102
00:09:41,730 --> 00:07:04,770
hooks today on a two-day journey to the

103
00:12:28,120 --> 00:09:44,050
suddenly us just became the era her

104
00:12:33,079 --> 00:12:31,310
all right thank you guys very very much

105
00:12:34,700 --> 00:12:33,089
for that wonderful video you guys

106
00:12:35,930 --> 00:12:34,710
obviously had some great experiences I

107
00:12:36,650 --> 00:12:35,940
hope you guys will share with everybody

108
00:12:38,900 --> 00:12:36,660
today

109
00:12:40,220 --> 00:12:38,910
on this hangout just a reminder for

110
00:12:41,510 --> 00:12:40,230
everybody who's watching we're taking

111
00:12:44,450 --> 00:12:41,520
real-time questions using the hashtag

112
00:12:46,670 --> 00:12:44,460
found ask NASA on Twitter or from the

113
00:12:48,050 --> 00:12:46,680
NASA Google+ page doing this event we've

114
00:12:49,400 --> 00:12:48,060
also opened up a thread on NASA's

115
00:12:51,620 --> 00:12:49,410
Facebook page where you can also post

116
00:12:52,850 --> 00:12:51,630
your questions without any further ado

117
00:12:54,410 --> 00:12:52,860
we're gonna go to our very first

118
00:13:02,420 --> 00:12:54,420
question from the doulton Intermediate

119
00:13:04,940 --> 00:13:02,430
School my name is Jackie I am an eighth

120
00:13:10,070 --> 00:13:04,950
grade student at Downton Intermediate

121
00:13:14,329 --> 00:13:10,080
School where either of you afraid during

122
00:13:17,540 --> 00:13:14,339
the spacewalks and how are you protected

123
00:13:23,720 --> 00:13:17,550
from the sun's radiation when you are on

124
00:13:25,600 --> 00:13:23,730
a spacewalk well heck yeah it's it's a

125
00:13:28,400 --> 00:13:25,610
little scary out there sometimes

126
00:13:31,190 --> 00:13:28,410
particularly when you look down and you

127
00:13:34,130 --> 00:13:31,200
see the earth zipping zipping by you at

128
00:13:35,810 --> 00:13:34,140
like a 17,000 miles an hour but you know

129
00:13:39,019 --> 00:13:35,820
we're trained pretty well you saw us

130
00:13:40,940 --> 00:13:39,029
doing all this stuff in the pool so we

131
00:13:42,380 --> 00:13:40,950
know what would our tasks are we know

132
00:13:43,820 --> 00:13:42,390
what we have to do when we get out there

133
00:13:46,230 --> 00:13:43,830
I really want to work and make sure we

134
00:13:48,449 --> 00:13:46,240
get that stuff done so you

135
00:13:50,610 --> 00:13:48,459
lie on the things that you that you

136
00:13:52,650 --> 00:13:50,620
learned for many years we did about two

137
00:13:54,780 --> 00:13:52,660
and a half years of training so you rely

138
00:13:57,180 --> 00:13:54,790
on their skills and you rely on each

139
00:13:58,889 --> 00:13:57,190
other as a team in case something

140
00:14:00,870 --> 00:13:58,899
happens to you the other guys gonna

141
00:14:03,120 --> 00:14:00,880
rescue you so you know we're pretty good

142
00:14:05,400 --> 00:14:03,130
buddies at this point in time that we

143
00:14:06,420 --> 00:14:05,410
our lifes depend on each other and yeah

144
00:14:09,210 --> 00:14:06,430
of course we have to worry about

145
00:14:12,000 --> 00:14:09,220
radiation but the suits have multiple

146
00:14:13,860 --> 00:14:12,010
layers of material to help us stay

147
00:14:15,630 --> 00:14:13,870
protected and so does the spacecraft

148
00:14:18,030 --> 00:14:15,640
itself the whole spacecraft has some

149
00:14:20,310 --> 00:14:18,040
protection on it of course we do get

150
00:14:22,320 --> 00:14:20,320
some radiation and so we wear a little

151
00:14:25,260 --> 00:14:22,330
dosimeter with us all the time so we

152
00:14:26,639 --> 00:14:25,270
come back to earth they can put that in

153
00:14:29,400 --> 00:14:26,649
a machine and they can understand how

154
00:14:30,900 --> 00:14:29,410
much radiation we do get and actually

155
00:14:32,910 --> 00:14:30,910
some folks on the ground are watching

156
00:14:35,760 --> 00:14:32,920
for solar flares and other big events

157
00:14:37,470 --> 00:14:35,770
like that that could help you know hurt

158
00:14:39,389 --> 00:14:37,480
us with the radiation and if it really

159
00:14:41,340 --> 00:14:39,399
gets bad and they detect that they know

160
00:14:43,380 --> 00:14:41,350
that they could tell us to go to a safe

161
00:14:45,810 --> 00:14:43,390
place on the space station to try to be

162
00:14:59,540 --> 00:14:45,820
a little bit further protected from the

163
00:15:06,300 --> 00:15:05,040
we're not hearing you sorry guys we're

164
00:15:07,949 --> 00:15:06,310
gonna go to our next question here from

165
00:15:16,440 --> 00:15:07,959
Our Lady of Perpetual Help Catholic

166
00:15:20,010 --> 00:15:16,450
school I'm Reagan this is kit

167
00:15:21,990 --> 00:15:20,020
Caroline and we'll our question how does

168
00:15:24,240 --> 00:15:22,000
being in space to thank you emotionally

169
00:15:26,670 --> 00:15:24,250
is it difficult to be with the same

170
00:15:30,000 --> 00:15:26,680
people for so long how do you resolve

171
00:15:37,819 --> 00:15:30,010
disputes does airplane be alone

172
00:15:43,230 --> 00:15:40,139
it's interesting you asked about that

173
00:15:47,040 --> 00:15:43,240
question you know you saw the video of

174
00:15:49,290 --> 00:15:47,050
our training - we trained about two and

175
00:15:51,360 --> 00:15:49,300
a half years before we launched so by

176
00:15:54,510 --> 00:15:51,370
the time we watched and you know get

177
00:15:57,269 --> 00:15:54,520
stuffed in that mall no it's not small

178
00:15:59,550 --> 00:15:57,279
it's a big and can up there the space

179
00:16:00,150 --> 00:15:59,560
station but by that time we're like

180
00:16:02,910 --> 00:16:00,160
family

181
00:16:07,970 --> 00:16:02,920
and you know signs like a sister he was

182
00:16:10,500 --> 00:16:07,980
like a brother to me so it wasn't

183
00:16:13,530 --> 00:16:10,510
together there you work together really

184
00:16:18,930 --> 00:16:13,540
well by that time so we didn't have any

185
00:16:22,410 --> 00:16:18,940
problems so what about tears tears yes

186
00:16:26,280 --> 00:16:22,420
so I'm on earth I guess it comes down

187
00:16:28,170 --> 00:16:26,290
right on your cheek well it just fixed

188
00:16:30,120 --> 00:16:28,180
there and it gets bigger and bigger I

189
00:16:32,130 --> 00:16:30,130
had something in my eye

190
00:16:34,189 --> 00:16:32,140
one time and you know you're closing

191
00:16:37,220 --> 00:16:34,199
your eye and trying to get it out just

192
00:16:39,540 --> 00:16:37,230
your tears and it just you know

193
00:16:42,510 --> 00:16:39,550
accumulates right there and just stays

194
00:16:50,130 --> 00:16:42,520
there it's like a ball in front of your

195
00:16:52,860 --> 00:16:50,140
face thank you thank you thank you guys

196
00:16:53,670 --> 00:16:52,870
very much our next question comes from

197
00:16:56,850 --> 00:16:53,680
Google+

198
00:16:58,519 --> 00:16:56,860
it's from Nihar Palmer who says I get

199
00:17:00,689 --> 00:16:58,529
sick I get a sick feeling on

200
00:17:04,409 --> 00:17:00,699
merry-go-rounds I know many people don't

201
00:17:06,419 --> 00:17:04,419
so do keep eat do people like me have a

202
00:17:08,320 --> 00:17:06,429
problem with space-related training and

203
00:17:11,550 --> 00:17:08,330
g-forces etc

204
00:17:13,650 --> 00:17:11,560
and how does that affect you injuries

205
00:17:15,880 --> 00:17:13,660
well I think you know you're

206
00:17:18,610 --> 00:17:15,890
uncomfortable with anything that's a

207
00:17:21,220 --> 00:17:18,620
little out of the ordinary at first I

208
00:17:23,350 --> 00:17:21,230
think for all of us to you know we fly

209
00:17:24,930 --> 00:17:23,360
airplanes and the first time I got into

210
00:17:28,480 --> 00:17:24,940
an airplane I didn't feel so good

211
00:17:30,040 --> 00:17:28,490
sitting in there was high and it was you

212
00:17:31,600 --> 00:17:30,050
know we were flying up you know loops

213
00:17:33,790 --> 00:17:31,610
and turns and stuff like that and I

214
00:17:35,710 --> 00:17:33,800
didn't feel so good but you know you get

215
00:17:38,620 --> 00:17:35,720
used to it your body really can adapt

216
00:17:40,750 --> 00:17:38,630
earlier if you're in good health so you

217
00:17:42,460 --> 00:17:40,760
can know what your body actually really

218
00:17:44,560 --> 00:17:42,470
what's cool about it it remembers the

219
00:17:46,510 --> 00:17:44,570
things that it's gone through before and

220
00:17:48,910 --> 00:17:46,520
you could work through some of those

221
00:17:50,800 --> 00:17:48,920
things for sure you know when I first

222
00:17:53,590 --> 00:17:50,810
went to space my first time I felt

223
00:17:55,420 --> 00:17:53,600
pretty sick so this time I was waiting

224
00:17:57,220 --> 00:17:55,430
for myself to get pretty sick and I

225
00:17:59,440 --> 00:17:57,230
think all sudden my brain goes oh yeah

226
00:18:01,450 --> 00:17:59,450
you didn't before it's like old news so

227
00:18:04,030 --> 00:18:01,460
I didn't get sick the second time so

228
00:18:05,320 --> 00:18:04,040
absolutely you can adapt so if you're

229
00:18:07,450 --> 00:18:05,330
don't worry about the merry-go-round

230
00:18:10,600 --> 00:18:07,460
then get back on that horse as they say

231
00:18:12,820 --> 00:18:10,610
and try it again and one advice I have

232
00:18:14,110 --> 00:18:12,830
for you is when if you do start to feel

233
00:18:16,630 --> 00:18:14,120
a little sick just look out toward the

234
00:18:18,130 --> 00:18:16,640
horizon if you look far focus far away

235
00:18:19,930 --> 00:18:18,140
and not really writing on what you're

236
00:18:25,660 --> 00:18:19,940
doing it seems to help you with getting

237
00:18:27,310 --> 00:18:25,670
any type of motion sickness alright our

238
00:18:30,580 --> 00:18:27,320
next question comes from Facebook here

239
00:18:32,380 --> 00:18:30,590
from Ian tanum who says I noticed that

240
00:18:33,310 --> 00:18:32,390
both of you have flown on both the Space

241
00:18:36,190 --> 00:18:33,320
Shuttle and I saw you

242
00:18:37,900 --> 00:18:36,200
what are some things that you liked or

243
00:18:41,860 --> 00:18:37,910
disliked or found unique about each

244
00:18:44,290 --> 00:18:41,870
spacecraft well you know it's a few

245
00:18:45,940 --> 00:18:44,300
different spacecrafts it's not you know

246
00:18:47,830 --> 00:18:45,950
one is better than the other you know

247
00:18:50,080 --> 00:18:47,840
Space Shuttle was designed to do so many

248
00:18:51,730 --> 00:18:50,090
things it can you know go up to the

249
00:18:54,910 --> 00:18:51,740
space station it can be its own

250
00:18:57,880 --> 00:18:54,920
laboratory and stay up in space for a

251
00:18:59,920 --> 00:18:57,890
week or two it can deploy satellite I

252
00:19:02,320 --> 00:18:59,930
can go to the Hubble telescope to repair

253
00:19:05,320 --> 00:19:02,330
it on the other hand the Soyuz

254
00:19:08,290 --> 00:19:05,330
spacecraft is really reliable to to

255
00:19:10,570 --> 00:19:08,300
bring people to station and then back

256
00:19:13,420 --> 00:19:10,580
and it also serves as a lifeboat

257
00:19:15,670 --> 00:19:13,430
now the Space Shuttle we can fit every

258
00:19:17,950 --> 00:19:15,680
people on the other hand the Soyuz only

259
00:19:21,370 --> 00:19:17,960
three and it's much smaller you know we

260
00:19:22,390 --> 00:19:21,380
were like like this crammed in there for

261
00:19:25,240 --> 00:19:22,400
two days

262
00:19:27,790 --> 00:19:25,250
and it's it is tight but it's reliable

263
00:19:31,570 --> 00:19:27,800
and for launch and landing we kind of

264
00:19:34,360 --> 00:19:31,580
joke around that we like to want I in a

265
00:19:37,150 --> 00:19:34,370
Soyuz spacecraft and then land on the

266
00:19:39,550 --> 00:19:37,160
shuttle because you know for launch the

267
00:19:42,580 --> 00:19:39,560
shuttle has this vibration because it

268
00:19:44,800 --> 00:19:42,590
has solid rocket boosters the Soyuz

269
00:19:48,790 --> 00:19:44,810
rocket has only liquid engines so it's a

270
00:19:50,890 --> 00:19:48,800
really a smooth ride for landing of

271
00:19:53,350 --> 00:19:50,900
course you know shuttle is like smooth

272
00:19:56,500 --> 00:19:53,360
glider just glides in and touches down

273
00:19:58,240 --> 00:19:56,510
on the runway whereas the Soyuz it just

274
00:20:00,370 --> 00:19:58,250
hits the ground we call it a soft

275
00:20:03,240 --> 00:20:00,380
landing but yeah you know what what that

276
00:20:06,460 --> 00:20:03,250
really means so there are differences

277
00:20:10,720 --> 00:20:06,470
can't really say which is better and

278
00:20:12,310 --> 00:20:10,730
it's just different all right wonderful

279
00:20:15,820 --> 00:20:12,320
we're gonna take our next question from

280
00:20:17,290 --> 00:20:15,830
Dalton Intermediate School my name is

281
00:20:18,970 --> 00:20:17,300
Christopher I am in the eighth grade

282
00:20:21,640 --> 00:20:18,980
stem class at downe Intermediate School

283
00:20:23,380 --> 00:20:21,650
we wrote a proposal for an experiment to

284
00:20:25,690 --> 00:20:23,390
be done in the Portland State University

285
00:20:32,550 --> 00:20:25,700
drop tower can you talk to us about how

286
00:20:36,160 --> 00:20:32,560
liquids behave in microgravity hey so I

287
00:20:38,650 --> 00:20:36,170
I don't know if you met dr. mark wangle

288
00:20:41,380 --> 00:20:38,660
who's part of the the Portland State

289
00:20:43,570 --> 00:20:41,390
drop tower he's a good friend of ours

290
00:20:45,370 --> 00:20:43,580
and he designed the capillary flow

291
00:20:46,900 --> 00:20:45,380
experiment that we did up on the space

292
00:20:50,350 --> 00:20:46,910
station that's been going on for quite

293
00:20:52,720 --> 00:20:50,360
some time it's pretty cool liquids do

294
00:20:54,460 --> 00:20:52,730
really neat things they form big spheres

295
00:20:54,970 --> 00:20:54,470
like if you see water coming out of a

296
00:20:56,950 --> 00:20:54,980
straw

297
00:21:00,580 --> 00:20:56,960
it doesn't forms this big cool sphere

298
00:21:02,440 --> 00:21:00,590
that you can use in in for washing your

299
00:21:03,580 --> 00:21:02,450
face brushing your teeth and all that

300
00:21:05,080 --> 00:21:03,590
kind of stuff

301
00:21:07,750 --> 00:21:05,090
but and that's just out in the open

302
00:21:09,550 --> 00:21:07,760
aspects atmosphere the capillary flow

303
00:21:12,330 --> 00:21:09,560
experiments were really awesome because

304
00:21:16,480 --> 00:21:12,340
they used different shapes within a

305
00:21:18,550 --> 00:21:16,490
vessel to make liquid take advantage of

306
00:21:20,590 --> 00:21:18,560
capillary flow without gravity so you

307
00:21:22,360 --> 00:21:20,600
can actually move liquid from one place

308
00:21:25,480 --> 00:21:22,370
to another which has really cool

309
00:21:27,610 --> 00:21:25,490
applications for maybe future fuel tanks

310
00:21:29,230 --> 00:21:27,620
and stuff like that so yeah I think

311
00:21:31,810 --> 00:21:29,240
we're pretty familiar with the work that

312
00:21:33,700 --> 00:21:31,820
those guys did we had the pleasure of

313
00:21:35,920 --> 00:21:33,710
doing more and more of their experiments

314
00:21:38,650 --> 00:21:35,930
up in space to see how

315
00:21:41,050 --> 00:21:38,660
liquids flow different viscosities and

316
00:21:42,970 --> 00:21:41,060
how we could take advantage of capillary

317
00:21:45,880 --> 00:21:42,980
flow in space because it's a something

318
00:21:49,210 --> 00:21:45,890
unique for space travel spacecraft so

319
00:21:50,410 --> 00:21:49,220
you guys I'm excited for you to be

320
00:21:52,210 --> 00:21:50,420
working with those guys they're pretty

321
00:21:58,210 --> 00:21:52,220
smart people so I hope you're having fun

322
00:21:59,470 --> 00:21:58,220
with them all right thank you wonderful

323
00:22:01,120 --> 00:21:59,480
we're gonna take our next question here

324
00:22:12,250 --> 00:22:01,130
from Our Lady of Perpetual helps

325
00:22:14,620 --> 00:22:12,260
Catholic school what happens if someone

326
00:22:17,530 --> 00:22:14,630
is seriously injured on a space station

327
00:22:19,570 --> 00:22:17,540
do bones heal differently when you get a

328
00:22:25,690 --> 00:22:19,580
cut is bleeding affected by the lack of

329
00:22:27,460 --> 00:22:25,700
gravity well first of all once our crew

330
00:22:29,770 --> 00:22:27,470
unfortunately we didn't have a medical

331
00:22:31,510 --> 00:22:29,780
doctor you know if it was we would be

332
00:22:34,000 --> 00:22:31,520
lucky if we had a medical doctor amongst

333
00:22:36,850 --> 00:22:34,010
the crew but we didn't so what do we do

334
00:22:39,370 --> 00:22:36,860
we have people called the crew Medical

335
00:22:41,170 --> 00:22:39,380
Officer get trained and actually Sonny

336
00:22:44,140 --> 00:22:41,180
and I were the crew medical officers

337
00:22:46,630 --> 00:22:44,150
one's an engineer one's a pilot but we

338
00:22:49,540 --> 00:22:46,640
still got training and we were able to

339
00:22:52,030 --> 00:22:49,550
you know help out if necessary of course

340
00:22:55,840 --> 00:22:52,040
we have doctors on the ground that would

341
00:22:57,850 --> 00:22:55,850
help us if we had an emergency we will

342
00:23:00,670 --> 00:22:57,860
talk to them and they'll give us some

343
00:23:03,310 --> 00:23:00,680
instructions and of course comes to

344
00:23:08,220 --> 00:23:03,320
worst we'll hear we'll get in our Soyuz

345
00:23:12,580 --> 00:23:08,230
and come back to earth for more help and

346
00:23:15,250 --> 00:23:12,590
well bounine what I don't know what

347
00:23:18,420 --> 00:23:15,260
happens to blood what happens to a cut

348
00:23:21,850 --> 00:23:18,430
all right I had a cut a little bit but I

349
00:23:25,150 --> 00:23:21,860
think it was not the same as it killed

350
00:23:26,740 --> 00:23:25,160
well just like on earth yeah I mean

351
00:23:28,990 --> 00:23:26,750
blood blood itself is just like another

352
00:23:30,580 --> 00:23:29,000
fluid so it's gonna fall up and make a

353
00:23:33,040 --> 00:23:30,590
ball if it gets loose and goes

354
00:23:35,110 --> 00:23:33,050
everywhere but we we took blood samples

355
00:23:36,730 --> 00:23:35,120
and sometimes we had a little bit of a

356
00:23:39,250 --> 00:23:36,740
spillage but we tried to contain that

357
00:23:40,840 --> 00:23:39,260
and luckily you I don't know if you

358
00:23:42,480 --> 00:23:40,850
could really break a bone in space it

359
00:23:44,800 --> 00:23:42,490
would be hard unless something sort of

360
00:23:48,170 --> 00:23:44,810
squished you because you know you're not

361
00:23:50,150 --> 00:23:48,180
falling or anything like that so

362
00:23:52,100 --> 00:23:50,160
we really I think the chances of

363
00:23:53,720 --> 00:23:52,110
breaking a bone might be pretty slim I'm

364
00:23:55,520 --> 00:23:53,730
not sure how that would heal though

365
00:23:57,080 --> 00:23:55,530
because bone density is a big problem

366
00:23:59,270 --> 00:23:57,090
which you probably can't you know

367
00:24:01,430 --> 00:23:59,280
generated this question so that might

368
00:24:03,140 --> 00:24:01,440
that could be really troublesome if you

369
00:24:05,420 --> 00:24:03,150
did have a broken bone in space for the

370
00:24:07,130 --> 00:24:05,430
healing of that so a great question and

371
00:24:09,080 --> 00:24:07,140
of course we have all the medications on

372
00:24:11,150 --> 00:24:09,090
board all the medical equipment if

373
00:24:18,790 --> 00:24:11,160
necessary if someone has a toothache we

374
00:24:24,260 --> 00:24:20,750
wonderful our next question comes from

375
00:24:26,180 --> 00:24:24,270
Twitter user at I'm hunter Smith hi I'm

376
00:24:28,100 --> 00:24:26,190
hunter I wanted to ask if you believe

377
00:24:31,630 --> 00:24:28,110
that life exists on other planets give

378
00:24:36,530 --> 00:24:34,760
well in our solar system I'm not exactly

379
00:24:39,590 --> 00:24:36,540
sure you know we're looking at Mars and

380
00:24:41,210 --> 00:24:39,600
that's why the most likely candidate but

381
00:24:43,010 --> 00:24:41,220
you know there's there's a million stars

382
00:24:45,290 --> 00:24:43,020
out there I think you guys can see it

383
00:24:46,910 --> 00:24:45,300
from where you are at night we could

384
00:24:48,590 --> 00:24:46,920
really see how many stars there were

385
00:24:50,930 --> 00:24:48,600
from the space station cuz we had that

386
00:24:53,180 --> 00:24:50,940
you know it's like a pair of nice pair

387
00:24:55,370 --> 00:24:53,190
of glasses without any humidity in the

388
00:24:57,770 --> 00:24:55,380
atmosphere to really see all of those

389
00:25:00,140 --> 00:24:57,780
stars out there in their full glory and

390
00:25:02,480 --> 00:25:00,150
actually see 3d as we look out into the

391
00:25:04,040 --> 00:25:02,490
universe so you know what's the

392
00:25:06,350 --> 00:25:04,050
probability there's millions of stars

393
00:25:08,720 --> 00:25:06,360
there's probably a couple planets or

394
00:25:10,940 --> 00:25:08,730
some planets orbiting at least a couple

395
00:25:12,410 --> 00:25:10,950
of a lot of those stars out there so the

396
00:25:15,650 --> 00:25:12,420
probability that there's going to be

397
00:25:17,630 --> 00:25:15,660
another earth-like third Rock from a

398
00:25:20,030 --> 00:25:17,640
star that is similar to ours yeah I

399
00:25:22,190 --> 00:25:20,040
would I would imagine that's probably is

400
00:25:24,260 --> 00:25:22,200
some life out there somewhere it just

401
00:25:25,850 --> 00:25:24,270
might be a little bit difficult for us

402
00:25:28,880 --> 00:25:25,860
to get there with our current engine

403
00:25:30,860 --> 00:25:28,890
technology so we need to work on that so

404
00:25:33,350 --> 00:25:30,870
we can zip around the universe a little

405
00:25:34,880 --> 00:25:33,360
quicker than we can today but like for

406
00:25:36,140 --> 00:25:34,890
our solar system Mars might be a

407
00:25:38,420 --> 00:25:36,150
candidate so that's why we have

408
00:25:40,550 --> 00:25:38,430
curiosity and other Rovers there in the

409
00:25:42,500 --> 00:25:40,560
future going there and hopefully you

410
00:25:44,390 --> 00:25:42,510
guys will be going there before too long

411
00:25:47,620 --> 00:25:44,400
as well to check it out with your own

412
00:25:52,400 --> 00:25:50,810
wonderful that's an awesome answer just

413
00:25:54,170 --> 00:25:52,410
a reminder for our online audience here

414
00:25:56,300 --> 00:25:54,180
we're taking real-time questions using

415
00:25:59,180 --> 00:25:56,310
the hashtag pound to ask NASA on Twitter

416
00:26:01,130 --> 00:25:59,190
and from NASA's Google+ page we've also

417
00:26:02,030 --> 00:26:01,140
opened up a comment thread on NASA's

418
00:26:04,460 --> 00:26:02,040
Facebook page where you

419
00:26:07,130 --> 00:26:04,470
host your questions as well our next

420
00:26:11,180 --> 00:26:07,140
question here comes from Twitter its

421
00:26:13,070 --> 00:26:11,190
user six of seven since the end of the

422
00:26:14,210 --> 00:26:13,080
space race the general public has not

423
00:26:16,580 --> 00:26:14,220
been as fascinating in this case

424
00:26:20,920 --> 00:26:16,590
exploration how do you think we can get

425
00:26:25,040 --> 00:26:23,390
well I hope we're doing it a little bit

426
00:26:27,560 --> 00:26:25,050
by doing this and talking to people in

427
00:26:29,060 --> 00:26:27,570
all these different social media venues

428
00:26:30,590 --> 00:26:29,070
that are out there nowadays because your

429
00:26:33,470 --> 00:26:30,600
generation is the one that's going to do

430
00:26:36,050 --> 00:26:33,480
a lot of exciting stuff you know when we

431
00:26:38,060 --> 00:26:36,060
first started flying and during the

432
00:26:39,440 --> 00:26:38,070
astronaut program we were flying the

433
00:26:41,270 --> 00:26:39,450
space shuttle and now the spatial of

434
00:26:43,910 --> 00:26:41,280
course is not flying anymore but what's

435
00:26:45,770 --> 00:26:43,920
good about that is you know that means

436
00:26:48,620 --> 00:26:45,780
we have money and time to dedicate to

437
00:26:50,420 --> 00:26:48,630
new programs and build spacecraft that

438
00:26:52,820 --> 00:26:50,430
will go out of low Earth orbit so I

439
00:26:54,290 --> 00:26:52,830
think what we have to do is just try to

440
00:26:56,450 --> 00:26:54,300
make sure we reach the next generation

441
00:26:58,640 --> 00:26:56,460
and know and make sure that they know

442
00:27:00,410 --> 00:26:58,650
that there are lots of opportunities out

443
00:27:02,960 --> 00:27:00,420
there and actually bigger and better

444
00:27:04,730 --> 00:27:02,970
things that you guys are gonna do then

445
00:27:06,590 --> 00:27:04,740
what we did you know if you thought we

446
00:27:08,750 --> 00:27:06,600
did was cool you guys are gonna go

447
00:27:11,330 --> 00:27:08,760
farther away from this planet and see

448
00:27:13,490 --> 00:27:11,340
our earth actually as a whole sphere how

449
00:27:15,290 --> 00:27:13,500
cool would that be you know we just are

450
00:27:16,880 --> 00:27:15,300
in low-earth orbit you guys are the ones

451
00:27:20,480 --> 00:27:16,890
who are gonna go back to the moon onto

452
00:27:22,580 --> 00:27:20,490
an asteroid and possibly to Mars so I

453
00:27:24,320 --> 00:27:22,590
think it's exciting I just think you

454
00:27:25,790 --> 00:27:24,330
guys have to be know that you're gonna

455
00:27:27,290 --> 00:27:25,800
do it you have to be determined and

456
00:27:29,570 --> 00:27:27,300
ready to get to take those

457
00:27:31,100 --> 00:27:29,580
responsibilities because you guys will

458
00:27:38,440 --> 00:27:31,110
you'll be the ones that will be watching

459
00:27:41,360 --> 00:27:40,310
wonderful before we go back to the

460
00:27:42,860 --> 00:27:41,370
schools we just got a really good

461
00:27:45,530 --> 00:27:42,870
question here on Twitter from miss band

462
00:27:50,420 --> 00:27:45,540
room 23 what's the scariest thing that

463
00:28:03,980 --> 00:27:50,430
you've come across in space mmm scariest

464
00:28:07,070 --> 00:28:03,990
thing I don't know maybe sunny I was

465
00:28:10,820 --> 00:28:07,080
never scared I thought I would be very

466
00:28:12,590 --> 00:28:10,830
nervous for launch because that's a very

467
00:28:15,769 --> 00:28:12,600
critical moment and you know it's the

468
00:28:18,139 --> 00:28:15,779
first step but going up to space but

469
00:28:20,209 --> 00:28:18,149
or my two flights first I'm a shuttle

470
00:28:22,039 --> 00:28:20,219
Discovery and this time on the Soyuz I

471
00:28:25,159 --> 00:28:22,049
felt really comfortable and that's

472
00:28:28,339 --> 00:28:25,169
because you've trained so many times and

473
00:28:30,440 --> 00:28:28,349
you see things just like you trained and

474
00:28:32,709 --> 00:28:30,450
also because you're together with your

475
00:28:35,359 --> 00:28:32,719
families you know sunny yuri malenchenko

476
00:28:37,099 --> 00:28:35,369
we were together on the soyuz on the

477
00:28:38,779 --> 00:28:37,109
launch pad and we trained together for

478
00:28:41,149 --> 00:28:38,789
two and a half years so we're family

479
00:28:43,820 --> 00:28:41,159
like I said and you're there together

480
00:28:45,889 --> 00:28:43,830
with them so I think that's why I felt

481
00:28:48,859 --> 00:28:45,899
comfortable so other than that I don't

482
00:28:54,440 --> 00:28:48,869
know I never had a something that scared

483
00:28:55,579 --> 00:28:54,450
me wonderful then we're gonna take our

484
00:28:59,959 --> 00:28:55,589
next question from the Dalton

485
00:29:01,849 --> 00:28:59,969
Intermediate School hi my name is Alex

486
00:29:04,190 --> 00:29:01,859
plants I am in the seventh grade at

487
00:29:05,810 --> 00:29:04,200
Dalton an intermediate sculpt when you

488
00:29:07,909 --> 00:29:05,820
are at on the International Space

489
00:29:10,969 --> 00:29:07,919
Station how long does it take you to

490
00:29:13,009 --> 00:29:10,979
orbit Earth also have you ever seen the

491
00:29:17,269 --> 00:29:13,019
Great Wall of China or the Grand Canyon

492
00:29:20,509 --> 00:29:17,279
from space yeah so we we go and people

493
00:29:22,310 --> 00:29:20,519
say this big number right is 17,500

494
00:29:24,079 --> 00:29:22,320
miles an hour approximately is how fast

495
00:29:26,269 --> 00:29:24,089
we're traveling so what that means it

496
00:29:29,180 --> 00:29:26,279
takes about 90 minutes to go all the way

497
00:29:31,969 --> 00:29:29,190
across the planet about five miles a

498
00:29:35,419 --> 00:29:31,979
second around the planet rather five

499
00:29:38,029 --> 00:29:35,429
miles a second so we have 45 minutes

500
00:29:40,519 --> 00:29:38,039
proximately of day time about 45 minutes

501
00:29:42,889 --> 00:29:40,529
of night time as we're as we're floating

502
00:29:46,039 --> 00:29:42,899
around but luckily they have lights on

503
00:29:48,139 --> 00:29:46,049
the ceiling on the ceiling in the space

504
00:29:49,639 --> 00:29:48,149
station and so we keep the lights on for

505
00:29:52,369 --> 00:29:49,649
the daytime and then we turn the lights

506
00:29:54,349 --> 00:29:52,379
off for our night time so we try to get

507
00:29:57,529 --> 00:29:54,359
a normal nighttime sleep just like you

508
00:29:59,479 --> 00:29:57,539
guys do back on earth and I don't know

509
00:30:02,749 --> 00:29:59,489
my Chinese geography as well as I should

510
00:30:04,729 --> 00:30:02,759
so I was able to pick out some major

511
00:30:07,070 --> 00:30:04,739
towns but I wasn't able to see exactly

512
00:30:08,899 --> 00:30:07,080
where the Great Wall of China was did

513
00:30:10,700 --> 00:30:08,909
you see it and yeah actually I was

514
00:30:13,339 --> 00:30:10,710
trying to see it too

515
00:30:15,950 --> 00:30:13,349
you know we have a application on our

516
00:30:18,469 --> 00:30:15,960
laptop on board called world maps so you

517
00:30:20,869 --> 00:30:18,479
know the trajectory of the station and

518
00:30:24,829 --> 00:30:20,879
you know what is coming in the next

519
00:30:27,589 --> 00:30:24,839
orbit so I was trying to look for it and

520
00:30:29,550 --> 00:30:27,599
it is hard to see especially if that if

521
00:30:31,590 --> 00:30:29,560
there's no contrast

522
00:30:34,770 --> 00:30:31,600
Queen the environment and itself for

523
00:30:36,990 --> 00:30:34,780
instance the the pyramids in Egypt it is

524
00:30:39,390 --> 00:30:37,000
really hard unless you know exactly

525
00:30:42,480 --> 00:30:39,400
where it is then you can find it but

526
00:30:45,810 --> 00:30:42,490
it's hard to see if is you know brown on

527
00:30:47,490 --> 00:30:45,820
brown it's it's really hard to see now

528
00:30:51,750 --> 00:30:47,500
on the other hand if you have contrast

529
00:30:53,850 --> 00:30:51,760
it is easy to pick up like the runway at

530
00:30:57,960 --> 00:30:53,860
Kennedy Space Center it's easy to pick

531
00:30:58,800 --> 00:30:57,970
out Central Park in New York it was easy

532
00:31:01,890 --> 00:30:58,810
to pick out

533
00:31:04,860 --> 00:31:01,900
so those if you have contrast since it

534
00:31:06,690 --> 00:31:04,870
was easy to pick it out but I was not

535
00:31:08,880 --> 00:31:06,700
able to see the payroll of China either

536
00:31:11,160 --> 00:31:08,890
but we did see the Grand Canyon for sure

537
00:31:13,260 --> 00:31:11,170
and you know what that looked like I

538
00:31:15,210 --> 00:31:13,270
mean you have a vision of what it looks

539
00:31:17,040 --> 00:31:15,220
like in your mind from the pictures and

540
00:31:18,840 --> 00:31:17,050
when you can see you know the wall the

541
00:31:21,270 --> 00:31:18,850
edge and stuff like that that's not how

542
00:31:24,960 --> 00:31:21,280
it looks from space from space it really

543
00:31:28,140 --> 00:31:24,970
looks like something variegated and like

544
00:31:30,510 --> 00:31:28,150
a like a big crack and with layers on it

545
00:31:32,580 --> 00:31:30,520
from above it looks almost flat or like

546
00:31:34,650 --> 00:31:32,590
a pancake but you can see like a key

547
00:31:37,530 --> 00:31:34,660
said the contrast of the different

548
00:31:39,030 --> 00:31:37,540
pieces of the sides that are going

549
00:31:40,800 --> 00:31:39,040
closer and closer and closer to the

550
00:31:42,840 --> 00:31:40,810
Colorado River going through the center

551
00:31:44,640 --> 00:31:42,850
of it so yeah you could definitely see

552
00:31:47,100 --> 00:31:44,650
it and you could see how blue the water

553
00:31:49,470 --> 00:31:47,110
is that's going through it the contrast

554
00:31:51,600 --> 00:31:49,480
of the colors like bright are like

555
00:31:54,000 --> 00:31:51,610
goldish brown to blue it's very obvious

556
00:31:55,230 --> 00:31:54,010
so yeah we've sorted quite a few times

557
00:31:59,850 --> 00:31:55,240
as a matter of fact coming across the

558
00:32:01,080 --> 00:31:59,860
country thank you wonderful our next

559
00:32:21,990 --> 00:32:01,090
question comes from Our Lady of

560
00:32:24,150 --> 00:32:22,000
Perpetual Help Catholic school hey I

561
00:32:25,470 --> 00:32:24,160
think the question I would go a little

562
00:32:27,570 --> 00:32:25,480
bit soft in the background there but I

563
00:32:29,310 --> 00:32:27,580
think your question was how is it

564
00:32:37,210 --> 00:32:29,320
emotionally and physically coming back

565
00:32:43,930 --> 00:32:39,700
yeah that sounds about right okay all

566
00:32:45,580 --> 00:32:43,940
right so physically in you might have

567
00:32:47,740 --> 00:32:45,590
seen pictures of people coming back from

568
00:32:49,960 --> 00:32:47,750
space think you know that's the soft

569
00:32:52,690 --> 00:32:49,970
landing and the capsule bumps on the

570
00:32:55,270 --> 00:32:52,700
ground like a car crash we roll for a

571
00:32:57,040 --> 00:32:55,280
little bit and we and then the rescue

572
00:32:59,680 --> 00:32:57,050
forces come they open the hatch and then

573
00:33:01,960 --> 00:32:59,690
they pull us out of the spacecraft and

574
00:33:03,250 --> 00:33:01,970
you see people pulling us out and it's

575
00:33:04,690 --> 00:33:03,260
sort of funny because everyone goes oh

576
00:33:08,470 --> 00:33:04,700
my god you must have been incapacitated

577
00:33:10,210 --> 00:33:08,480
or is something wrong with you no it's

578
00:33:11,860 --> 00:33:10,220
just a little bit easier that's not like

579
00:33:14,380 --> 00:33:11,870
steps to get out of there it's just a

580
00:33:16,270 --> 00:33:14,390
little inconvenience to climb out of

581
00:33:18,690 --> 00:33:16,280
there and then plop on the ground and so

582
00:33:21,670 --> 00:33:18,700
the rescue forces actually pulled us out

583
00:33:23,710 --> 00:33:21,680
we could actually walk but the more

584
00:33:25,840 --> 00:33:23,720
difficulty thing was a little bit of the

585
00:33:28,870 --> 00:33:25,850
neurovestibular it's your head back and

586
00:33:31,110 --> 00:33:28,880
forth the balance of your inner ear and

587
00:33:34,450 --> 00:33:31,120
your brain net connection getting back

588
00:33:36,610 --> 00:33:34,460
situated back to gravity once again and

589
00:33:37,690 --> 00:33:36,620
so that takes probably a day or two

590
00:33:40,150 --> 00:33:37,700
until you're better

591
00:33:42,160 --> 00:33:40,160
we have exercise equipment on the space

592
00:33:44,920 --> 00:33:42,170
station a bike a treadmill and

593
00:33:46,900 --> 00:33:44,930
weightlifting equipment so that were

594
00:33:52,120 --> 00:33:46,910
bones and our muscles are pretty strong

595
00:33:54,310 --> 00:33:52,130
swear a belong now emotionally we it

596
00:33:56,650 --> 00:33:54,320
takes about 24 hours after landing for

597
00:33:58,630 --> 00:33:56,660
us to get back to the United States and

598
00:34:01,450 --> 00:33:58,640
that's where our family and friends are

599
00:34:03,880 --> 00:34:01,460
waiting for us and it is it is a little

600
00:34:06,550 --> 00:34:03,890
bit of a jolt to the system after being

601
00:34:08,500 --> 00:34:06,560
up there with only three or six people

602
00:34:10,900 --> 00:34:08,510
and then seeing a whole lot of people

603
00:34:12,400 --> 00:34:10,910
and seeing really the fit you're really

604
00:34:15,070 --> 00:34:12,410
close family and friends your parents

605
00:34:16,780 --> 00:34:15,080
and your husbands or wives or dogs or

606
00:34:20,350 --> 00:34:16,790
kids and you know the things that you

607
00:34:23,890 --> 00:34:20,360
really love it's a little overwhelming

608
00:34:26,260 --> 00:34:23,900
but soon enough your husband wears his

609
00:34:28,750 --> 00:34:26,270
dirty shoes in the house and your dog

610
00:34:31,480 --> 00:34:28,760
makes a mess and then you get tired of

611
00:34:33,160 --> 00:34:31,490
them again so I'm just joking but you

612
00:34:35,260 --> 00:34:33,170
know things get back to normal right

613
00:34:38,530 --> 00:34:35,270
away you can't avoid normal life on

614
00:34:41,260 --> 00:34:38,540
earth so it gets back and unfortunately

615
00:34:44,170 --> 00:34:41,270
we felt our bodies turning back to

616
00:34:46,720 --> 00:34:44,180
gravity and the pieces of microgravity

617
00:34:49,030 --> 00:34:46,730
slipping away as every second ticked by

618
00:34:50,980 --> 00:34:49,040
so a little sad to leave microgravity

619
00:34:55,450 --> 00:34:50,990
step by step

620
00:34:58,810 --> 00:34:55,460
thank you thank you wonderful

621
00:35:00,400 --> 00:34:58,820
so another Twitter user here asks how do

622
00:35:02,079 --> 00:35:00,410
you feel about the Soyuz launching and

623
00:35:07,200 --> 00:35:02,089
docking to the station in just six hours

624
00:35:12,849 --> 00:35:11,079
well so on our flight we actually had

625
00:35:15,310 --> 00:35:12,859
two days to Rhonda wind up with a

626
00:35:17,470 --> 00:35:15,320
station so that means we launched that

627
00:35:20,620 --> 00:35:17,480
was a long day and then we had two more

628
00:35:23,859 --> 00:35:20,630
days to get closer and closer to station

629
00:35:26,859 --> 00:35:23,869
what were we doing during that two days

630
00:35:29,859 --> 00:35:26,869
is we were doing some maneuvers getting

631
00:35:32,800 --> 00:35:29,869
closer so that we had to fire the

632
00:35:35,980 --> 00:35:32,810
Rockets a couple times but other than

633
00:35:39,130 --> 00:35:35,990
that we were just resting for like 15

634
00:35:42,520 --> 00:35:39,140
hours a day I thought I could sleep

635
00:35:45,940 --> 00:35:42,530
anywhere anytime as long as I could but

636
00:35:50,020 --> 00:35:45,950
the second day was tough for me

637
00:35:52,329 --> 00:35:50,030
so you know a six hour rendezvous it's

638
00:35:53,950 --> 00:35:52,339
cool you know you have to understand

639
00:35:56,320 --> 00:35:53,960
that it's going to be a longer day and

640
00:35:59,380 --> 00:35:56,330
at the very end it might be a very

641
00:36:01,570 --> 00:35:59,390
critical moment so fatigue is a factor

642
00:36:04,990 --> 00:36:01,580
but I think everyone has a good plan

643
00:36:08,620 --> 00:36:05,000
they can kind of download if something

644
00:36:11,859 --> 00:36:08,630
happens to the two-day rendezvous if

645
00:36:14,140 --> 00:36:11,869
necessary so we do have a plan I think

646
00:36:16,170 --> 00:36:14,150
it's a good idea and and it's kind of

647
00:36:20,560 --> 00:36:16,180
interesting to see the transition from

648
00:36:24,220 --> 00:36:20,570
two-day rendezvous to just six hours so

649
00:36:25,450 --> 00:36:24,230
going up you know you you've launched in

650
00:36:28,359 --> 00:36:25,460
the morning and then that afternoon

651
00:36:31,900 --> 00:36:28,369
you're already on the station and like

652
00:36:35,589 --> 00:36:31,910
spacex dragon you know we we had one

653
00:36:37,300 --> 00:36:35,599
dragon and we released it and then you

654
00:36:40,510 --> 00:36:37,310
know maybe it was lunch time I think

655
00:36:43,030 --> 00:36:40,520
when we released it by that evening it

656
00:36:45,940 --> 00:36:43,040
was already on on the ground or on the

657
00:36:48,460 --> 00:36:45,950
ocean so it's that quick nowadays so

658
00:36:53,920 --> 00:36:48,470
it's it doesn't take a long journey to

659
00:36:54,310 --> 00:36:53,930
go up to space so it's kind of cool very

660
00:36:56,680 --> 00:36:54,320
cool

661
00:36:59,829 --> 00:36:56,690
our next question here comes from a

662
00:37:01,540 --> 00:36:59,839
Heather BJ on Facebook how is it on your

663
00:37:03,370 --> 00:37:01,550
body to feel the effects of gravity

664
00:37:04,660 --> 00:37:03,380
after returning to Earth what exactly

665
00:37:06,569 --> 00:37:04,670
did you have to do to rehabilitate

666
00:37:09,160 --> 00:37:06,579
yourself

667
00:37:10,210 --> 00:37:09,170
so after coming back you know we talked

668
00:37:13,390 --> 00:37:10,220
a little bit about the neurovestibular

669
00:37:16,269 --> 00:37:13,400
stuff already that's the that's a big

670
00:37:19,359 --> 00:37:16,279
challenge but because you don't want to

671
00:37:21,279 --> 00:37:19,369
fall over in front of all your friends

672
00:37:23,589 --> 00:37:21,289
and so you you're working really hard

673
00:37:25,690 --> 00:37:23,599
and some people actually described Aki

674
00:37:27,309 --> 00:37:25,700
and I on our way home and was looking

675
00:37:28,749 --> 00:37:27,319
like zombies because you know you don't

676
00:37:31,900 --> 00:37:28,759
want to turn your head too much you sort

677
00:37:34,089 --> 00:37:31,910
of want to walk steady and still so that

678
00:37:36,489 --> 00:37:34,099
takes a little bit of time then we

679
00:37:38,079 --> 00:37:36,499
actually work with our trainers physical

680
00:37:41,079 --> 00:37:38,089
trainers sort of like the gym teachers

681
00:37:43,150 --> 00:37:41,089
in a gym back at Johnson Space Center

682
00:37:45,489 --> 00:37:43,160
and we go through a lot of exercises to

683
00:37:47,739 --> 00:37:45,499
include a lot of stretching and then

684
00:37:50,049 --> 00:37:47,749
building slowly but surely in the

685
00:37:51,819 --> 00:37:50,059
weights to try to make sure that you can

686
00:37:54,220 --> 00:37:51,829
you're as strong as you were before you

687
00:37:55,660 --> 00:37:54,230
left and with the exercise equipment up

688
00:37:57,549 --> 00:37:55,670
and at the space station

689
00:37:59,710 --> 00:37:57,559
Aki and I within probably a couple of

690
00:38:02,259 --> 00:37:59,720
weeks were were right back to where we

691
00:38:05,559 --> 00:38:02,269
were before we left one of the

692
00:38:08,079 --> 00:38:05,569
overarching things that I felt also

693
00:38:09,309 --> 00:38:08,089
those was I was tired you know maybe we

694
00:38:10,720 --> 00:38:09,319
were working quite a bit while we're up

695
00:38:12,700 --> 00:38:10,730
on the space station that might have got

696
00:38:14,979 --> 00:38:12,710
us tired but I think it's actually just

697
00:38:17,140 --> 00:38:14,989
gravity you know up in space you don't

698
00:38:18,519 --> 00:38:17,150
your body's not fighting against gravity

699
00:38:20,829 --> 00:38:18,529
little do you guys know your heads are

700
00:38:22,870 --> 00:38:20,839
very heavy when you come back to earth

701
00:38:25,180 --> 00:38:22,880
takes a little bit of muscle to hold

702
00:38:27,670 --> 00:38:25,190
your head up and just to hold yourself

703
00:38:29,769 --> 00:38:27,680
up and you I think your body just has to

704
00:38:31,329 --> 00:38:29,779
get used to that and get you know get a

705
00:38:33,489 --> 00:38:31,339
little bit of sleep to make sure your

706
00:38:35,680 --> 00:38:33,499
muscles aren't regenerated correctly so

707
00:38:39,370 --> 00:38:35,690
I felt sleepy for about a month and now

708
00:38:42,960 --> 00:38:39,380
as you can tell I'm very peppy that's

709
00:38:46,779 --> 00:38:45,099
wonderful then one last question here

710
00:38:48,849 --> 00:38:46,789
from Twitter from app Peggy Lamberton

711
00:38:53,200 --> 00:38:48,859
are you both great at math and his math

712
00:38:55,599 --> 00:38:53,210
important to astronauts I don't know if

713
00:38:57,759 --> 00:38:55,609
I'm great at math but I liked it as an

714
00:39:01,239 --> 00:38:57,769
elementary student I really like math

715
00:39:04,720 --> 00:39:01,249
and it's like a problem-solving and it's

716
00:39:06,460 --> 00:39:04,730
like a game or a quiz to me so I really

717
00:39:09,640 --> 00:39:06,470
liked it I don't know if I was great or

718
00:39:11,349 --> 00:39:09,650
not but yeah I just liked it and I did

719
00:39:13,539 --> 00:39:11,359
well at math because I wanted to not

720
00:39:15,190 --> 00:39:13,549
have to carry my big fat math book home

721
00:39:17,380 --> 00:39:15,200
now you guys probably don't have that

722
00:39:18,410 --> 00:39:17,390
issue because you do try most of your

723
00:39:20,660 --> 00:39:18,420
stuff through

724
00:39:23,990 --> 00:39:20,670
computer but I used to get on my math

725
00:39:25,490 --> 00:39:24,000
homework done really quick so it I

726
00:39:27,859 --> 00:39:25,500
didn't have to do it later which I think

727
00:39:32,480 --> 00:39:27,869
made me good and quick at

728
00:39:34,039 --> 00:39:32,490
problem-solving apparently wonderful

729
00:39:35,480 --> 00:39:34,049
then just to remind our online audience

730
00:39:37,760 --> 00:39:35,490
here we're taking real-time questions

731
00:39:40,130 --> 00:39:37,770
using the hashtag pound asknasa on

732
00:39:42,710 --> 00:39:40,140
Twitter and from the NASA Google+ page

733
00:39:44,210 --> 00:39:42,720
you can also find a comment thread open

734
00:39:46,309 --> 00:39:44,220
on our NASA Facebook page where you can

735
00:39:47,180 --> 00:39:46,319
also post our questions our next

736
00:39:50,390 --> 00:39:47,190
question is going to come from the

737
00:39:51,890 --> 00:39:50,400
Dalton Intermediate School hi my name is

738
00:39:54,530 --> 00:39:51,900
James Moore Hart I'm in the eighth grade

739
00:39:56,359 --> 00:39:54,540
elementary medium school my question is

740
00:39:59,410 --> 00:39:56,369
do you need to learn other languages to

741
00:40:02,569 --> 00:39:59,420
work on the International Space Station

742
00:40:05,750 --> 00:40:02,579
he actually does speak Japanese can you

743
00:40:08,180 --> 00:40:05,760
believe it because I had to study you

744
00:40:10,339 --> 00:40:08,190
have to study Japanese that was my

745
00:40:13,400 --> 00:40:10,349
second language now I'm just kidding so

746
00:40:15,500 --> 00:40:13,410
so you know being in Japanese I had to

747
00:40:18,230 --> 00:40:15,510
learn English and Russian

748
00:40:21,160 --> 00:40:18,240
lucky for me I grew up in New Jersey so

749
00:40:25,549 --> 00:40:21,170
of English was not that big of a deal

750
00:40:27,400 --> 00:40:25,559
but learning Russian you know after what

751
00:40:30,799 --> 00:40:27,410
ten years after graduating from college

752
00:40:34,250 --> 00:40:30,809
that's a big deal I mean you you know

753
00:40:37,700 --> 00:40:34,260
you have to understand the grammar you

754
00:40:39,620 --> 00:40:37,710
have to learn new words and it took me

755
00:40:42,799 --> 00:40:39,630
like ten years to get to where I am

756
00:40:44,809 --> 00:40:42,809
right now but it's rewarding as well as

757
00:40:46,789 --> 00:40:44,819
you know you go to Star City you go to

758
00:40:50,599 --> 00:40:46,799
Russia you try to communicate with

759
00:40:54,559 --> 00:40:50,609
instructors and you know slowly but

760
00:40:56,450 --> 00:40:54,569
gradually you do get to be able to talk

761
00:40:58,960 --> 00:40:56,460
to them communicate with them in Russian

762
00:41:02,180 --> 00:40:58,970
and that was really rewarding and you do

763
00:41:06,260 --> 00:41:02,190
get to learn about the culture as well

764
00:41:09,170 --> 00:41:06,270
and and on board the space station

765
00:41:11,809 --> 00:41:09,180
English is the official language so

766
00:41:13,549 --> 00:41:11,819
everyone needs to study English

767
00:41:18,530 --> 00:41:13,559
including the Russian cosmonauts too and

768
00:41:21,109 --> 00:41:18,540
they do a great job we were talking on

769
00:41:23,599 --> 00:41:21,119
the space station in English but on the

770
00:41:26,390 --> 00:41:23,609
Soyuz capsule everything is in Russian

771
00:41:29,420 --> 00:41:26,400
because it's their vehicle so all the

772
00:41:31,339 --> 00:41:29,430
panel labels were in Russia and the the

773
00:41:32,180 --> 00:41:31,349
procedures are in Russia and all the

774
00:41:35,329 --> 00:41:32,190
communications

775
00:41:38,680 --> 00:41:35,339
rushon so we needed to learn that

776
00:41:40,640 --> 00:41:38,690
language dude thank you

777
00:41:42,650 --> 00:41:40,650
wonderful we're going to go to Our Lady

778
00:41:56,900 --> 00:41:42,660
of Perpetual Help Catholic school here

779
00:42:02,260 --> 00:41:56,910
for our next question they speak up a

780
00:42:05,569 --> 00:42:02,270
little bit louder our question is what

781
00:42:07,510 --> 00:42:05,579
what was your favorite part of and your

782
00:42:10,309 --> 00:42:07,520
least favorite part of being in space

783
00:42:14,540 --> 00:42:10,319
what was the coolest thing you saw or

784
00:42:16,760 --> 00:42:14,550
did in spaces well I think my favorite

785
00:42:18,440 --> 00:42:16,770
thing is the ability to fly I know I

786
00:42:19,849 --> 00:42:18,450
mean if you guys can look around the

787
00:42:21,319 --> 00:42:19,859
room where you're at right now look at

788
00:42:23,480 --> 00:42:21,329
the ceiling above you just think about

789
00:42:25,370 --> 00:42:23,490
pushing off the ground and floating

790
00:42:27,349 --> 00:42:25,380
right up to the ceiling and then doing a

791
00:42:30,470 --> 00:42:27,359
flip and pushing back down from one wall

792
00:42:32,480 --> 00:42:30,480
to the other flying is awesome I mean

793
00:42:34,130 --> 00:42:32,490
it's really it's like you know it makes

794
00:42:35,870 --> 00:42:34,140
me look at Birds and with a lot of envy

795
00:42:38,230 --> 00:42:35,880
nowadays when I see them zipping around

796
00:42:41,000 --> 00:42:38,240
on on tree branches and stuff like that

797
00:42:43,609 --> 00:42:41,010
flying is really really cool but you

798
00:42:46,670 --> 00:42:43,619
know what else is second part of that is

799
00:42:48,260 --> 00:42:46,680
not only we fly everything flies though

800
00:42:50,480 --> 00:42:48,270
one of the most annoying things about

801
00:42:51,920 --> 00:42:50,490
being in space is losing stuff you know

802
00:42:53,809 --> 00:42:51,930
here we can put you could just put

803
00:42:56,390 --> 00:42:53,819
something down on the table and it'll

804
00:42:58,400 --> 00:42:56,400
it'll be there it'll just stay there up

805
00:43:00,620 --> 00:42:58,410
in space if you just put something for a

806
00:43:03,200 --> 00:43:00,630
moment it's a lot of fun because you

807
00:43:04,760 --> 00:43:03,210
could just drop it it just hovers there

808
00:43:06,559 --> 00:43:04,770
for a little bit you can go do something

809
00:43:09,380 --> 00:43:06,569
and then hopefully when you come back

810
00:43:10,940 --> 00:43:09,390
it's there but nine times out of ten the

811
00:43:13,370 --> 00:43:10,950
air flow in the space station or

812
00:43:14,780 --> 00:43:13,380
somebody's foot comes by and kicks it

813
00:43:16,250 --> 00:43:14,790
and then you're not gonna find this

814
00:43:18,109 --> 00:43:16,260
thing for quite some time because it's

815
00:43:20,839 --> 00:43:18,119
not a life of its own and starts flying

816
00:43:22,790 --> 00:43:20,849
around so that was probably you know

817
00:43:25,040 --> 00:43:22,800
both the the best part in the worst part

818
00:43:27,530 --> 00:43:25,050
is that stuff flies around not only that

819
00:43:29,930 --> 00:43:27,540
like stuff flies in your hair like my

820
00:43:32,030 --> 00:43:29,940
hair was like full of dust you know and

821
00:43:34,130 --> 00:43:32,040
you know when you're eating something

822
00:43:35,089 --> 00:43:34,140
the cracker crumbs go all over the place

823
00:43:36,440 --> 00:43:35,099
so you don't want to have something

824
00:43:37,910 --> 00:43:36,450
that's crummy because then that's gonna

825
00:43:39,980 --> 00:43:37,920
get in your hair and your sleeping bag

826
00:43:42,319 --> 00:43:39,990
and stuff like that so those parts of

827
00:43:44,000 --> 00:43:42,329
the space are something that gets a

828
00:43:46,220 --> 00:43:44,010
little tiresome but you train yourself

829
00:43:47,750 --> 00:43:46,230
and you you know you take some Prakash

830
00:43:50,839 --> 00:43:47,760
so you don't have to worry about that I

831
00:43:53,359 --> 00:43:50,849
think the worst part of living in

832
00:43:55,819 --> 00:43:53,369
station and I think sunny agrees is that

833
00:43:58,130 --> 00:43:55,829
we had to come back home yeah to stay

834
00:44:03,880 --> 00:43:58,140
longer but we have to come back home

835
00:44:06,170 --> 00:44:03,890
that was worse part absolutely thank you

836
00:44:10,040 --> 00:44:06,180
wonderful our next question comes from

837
00:44:15,069 --> 00:44:10,050
Google+ our listen kitano says what is

838
00:44:19,250 --> 00:44:17,660
well the space suit is interesting you

839
00:44:19,730 --> 00:44:19,260
know because it's gonna it could save

840
00:44:22,609 --> 00:44:19,740
your life

841
00:44:25,310 --> 00:44:22,619
the reason we do wear space suits for

842
00:44:28,130 --> 00:44:25,320
launch and entry is just in case

843
00:44:30,460 --> 00:44:28,140
anything happens and the vehicle has a

844
00:44:32,810 --> 00:44:30,470
depressurization so the space suit is

845
00:44:34,790 --> 00:44:32,820
self-contained and make sure you're

846
00:44:36,410 --> 00:44:34,800
gonna be okay in there it's not super

847
00:44:39,319 --> 00:44:36,420
comfortable and neither is the big space

848
00:44:41,329 --> 00:44:39,329
walking soup but they they're it's hard

849
00:44:43,579 --> 00:44:41,339
to make a very safe suit comfortable and

850
00:44:45,829 --> 00:44:43,589
the gloves on all of those suits it's

851
00:44:47,780 --> 00:44:45,839
like if you want to go work on your

852
00:44:50,120 --> 00:44:47,790
computer and you had to wear our garden

853
00:44:51,890 --> 00:44:50,130
gloves all the time it's a little bit

854
00:44:54,410 --> 00:44:51,900
hard you know think about getting on

855
00:44:56,540 --> 00:44:54,420
your BlackBerry or your iPhone with big

856
00:44:59,030 --> 00:44:56,550
gloves on all the time this is it makes

857
00:45:01,099 --> 00:44:59,040
life a little bit troublesome they're

858
00:45:03,319 --> 00:45:01,109
usually a little bit rubbery type of

859
00:45:04,400 --> 00:45:03,329
plastic material to that you know they

860
00:45:07,250 --> 00:45:04,410
have to because they're a pressure

861
00:45:09,410 --> 00:45:07,260
bladder and so they cause a little bit

862
00:45:11,300 --> 00:45:09,420
of sweating and so everybody comes out

863
00:45:12,800 --> 00:45:11,310
of all of those suits just a little bit

864
00:45:15,109 --> 00:45:12,810
of sweaty and a little bit moist and

865
00:45:18,020 --> 00:45:15,119
sort of stinky so that's all it's not so

866
00:45:20,990 --> 00:45:18,030
nice and one other part of this the

867
00:45:22,550 --> 00:45:21,000
thing of course is we get we're in them

868
00:45:23,960 --> 00:45:22,560
for a long period of time you know it

869
00:45:26,150 --> 00:45:23,970
takes a little bit of time to get in

870
00:45:28,280 --> 00:45:26,160
them the launch and entry suits probably

871
00:45:30,500 --> 00:45:28,290
a half an hour each the spacesuit maybe

872
00:45:33,500 --> 00:45:30,510
45 minutes to an hour to actually get in

873
00:45:35,210 --> 00:45:33,510
that thing and so then you don't want to

874
00:45:37,990 --> 00:45:35,220
just put it on and take it off and so

875
00:45:42,079 --> 00:45:38,000
you're in it for a long time which means

876
00:45:44,690 --> 00:45:42,089
no go into the bathroom in a bathroom

877
00:45:46,940 --> 00:45:44,700
you have in all of those spaces who

878
00:45:50,089 --> 00:45:46,950
actually wear a diaper first and then

879
00:45:51,620 --> 00:45:50,099
you put long underwear and then a liquid

880
00:45:54,160 --> 00:45:51,630
cooling garment if you're going to go do

881
00:45:56,120 --> 00:45:54,170
a spacewalk a suit that has water

882
00:45:58,520 --> 00:45:56,130
circulating around it to cool you off

883
00:46:00,860 --> 00:45:58,530
and then the spacesuit goes on top and

884
00:46:03,470 --> 00:46:00,870
so it's multi-layer

885
00:46:06,020 --> 00:46:03,480
it's you know you have your own air that

886
00:46:07,520 --> 00:46:06,030
you're breathing inside so else I'll say

887
00:46:10,130 --> 00:46:07,530
that everything that you do is fairly

888
00:46:13,630 --> 00:46:10,140
self contained in there so don't eat

889
00:46:18,230 --> 00:46:13,640
beans before you put a spacesuit on and

890
00:46:20,570 --> 00:46:18,240
and it's not super super comfortable but

891
00:46:21,860 --> 00:46:20,580
it gets the job done and with their and

892
00:46:28,340 --> 00:46:21,870
they're needed for the things that we're

893
00:46:31,460 --> 00:46:28,350
using them for wonderful our next

894
00:46:34,190 --> 00:46:31,470
question comes from Irish space blog on

895
00:46:35,840 --> 00:46:34,200
Twitter Aki and sunny did the cupola

896
00:46:37,820 --> 00:46:35,850
make your overall spaceflight experience

897
00:46:43,640 --> 00:46:37,830
more enjoyable compared to previous

898
00:46:46,910 --> 00:46:43,650
flights yes it's a dangerous place that

899
00:46:48,710 --> 00:46:46,920
window that is a dangerous place in the

900
00:46:50,870 --> 00:46:48,720
space station I call it a black hole

901
00:46:52,870 --> 00:46:50,880
because you think hey I'll I'll take a

902
00:46:55,940 --> 00:46:52,880
peek outside the window for ten minutes

903
00:46:57,920 --> 00:46:55,950
you're stuck there for two hours you'd

904
00:47:01,040 --> 00:46:57,930
love it as you love it it's just

905
00:47:02,900 --> 00:47:01,050
gorgeous you see things fly by you know

906
00:47:07,100 --> 00:47:02,910
and then there's the next thing coming

907
00:47:09,140 --> 00:47:07,110
by you see deserts you see ocean you see

908
00:47:11,990 --> 00:47:09,150
mountains you see the night lights and

909
00:47:14,960 --> 00:47:12,000
it's just gorgeous and you can't leave

910
00:47:21,950 --> 00:47:14,970
so it is a dangerous place but we just

911
00:47:23,660 --> 00:47:21,960
loved it absolutely wonderful then our

912
00:47:26,300 --> 00:47:23,670
next question comes from Google+ here

913
00:47:28,760 --> 00:47:26,310
Patricia Fay asks are you fans of some

914
00:47:30,290 --> 00:47:28,770
of the science fiction genre or is your

915
00:47:36,590 --> 00:47:30,300
experience in space even better than

916
00:47:38,810 --> 00:47:36,600
fiction well I grew up watching Star

917
00:47:43,040 --> 00:47:38,820
Trek Star Wars you know I have a science

918
00:47:47,180 --> 00:47:43,050
fiction geek but you know it's one thing

919
00:47:48,980 --> 00:47:47,190
to watch those and imagine things and

920
00:47:52,520 --> 00:47:48,990
it's another to actually get to

921
00:47:55,580 --> 00:47:52,530
experience it I think everyone should go

922
00:47:58,460 --> 00:47:55,590
to space and experience it on their own

923
00:48:01,460 --> 00:47:58,470
because it's it's not the same as in

924
00:48:08,660 --> 00:48:01,470
your imaginated so it's it's really cool

925
00:48:12,539 --> 00:48:10,799
wonderful then for our online audience

926
00:48:14,099 --> 00:48:12,549
at home just a reminder that we're

927
00:48:17,069 --> 00:48:14,109
taking real-time questions using the

928
00:48:18,750 --> 00:48:17,079
hashtag pound to ask NASA on Twitter or

929
00:48:20,940 --> 00:48:18,760
we're taking them from our NASA Google+

930
00:48:22,710 --> 00:48:20,950
page we've also opened a comment thread

931
00:48:24,029 --> 00:48:22,720
for everybody on our NASA Facebook page

932
00:48:25,890 --> 00:48:24,039
where you can post your questions as

933
00:48:30,000 --> 00:48:25,900
well our next question is going to come

934
00:48:31,980 --> 00:48:30,010
from the Dalton Intermediate School my

935
00:48:34,079 --> 00:48:31,990
name is Kari I am an eighth grader at

936
00:48:36,089 --> 00:48:34,089
the Downton Intermediate School do you

937
00:48:39,720 --> 00:48:36,099
have any free time in the space station

938
00:48:45,359 --> 00:48:39,730
if you do what do you like to do do you

939
00:48:46,920 --> 00:48:45,369
have any fun of course we have fun we do

940
00:48:49,470 --> 00:48:46,930
have a little bit of free time every now

941
00:48:51,049 --> 00:48:49,480
and then yeah it wasn't all work up

942
00:48:53,970 --> 00:48:51,059
there wasn't all serious all the time

943
00:48:56,940 --> 00:48:53,980
and actually the work is really just fun

944
00:48:58,770 --> 00:48:56,950
anyway but we did try to have a normal

945
00:49:00,450 --> 00:48:58,780
day like I talked about we sort of got

946
00:49:03,450 --> 00:49:00,460
up at 6 o'clock in the morning started

947
00:49:05,609 --> 00:49:03,460
work around 7:00 7:30 and worked around

948
00:49:07,589 --> 00:49:05,619
it worked until around 6 o'clock at

949
00:49:09,240 --> 00:49:07,599
night 5 or 6 o'clock at night and then

950
00:49:12,059 --> 00:49:09,250
we had a little free time before we went

951
00:49:14,339 --> 00:49:12,069
to bed around 10 o'clock and so we ate

952
00:49:16,920 --> 00:49:14,349
dinner together we actually sort of

953
00:49:20,640 --> 00:49:16,930
gathered around a computer to watch some

954
00:49:23,640 --> 00:49:20,650
TV shows while we're eating dinner just

955
00:49:24,900 --> 00:49:23,650
sort of like a just a group thing to get

956
00:49:26,640 --> 00:49:24,910
together it's sort of just like at home

957
00:49:28,529 --> 00:49:26,650
we watched a little diners drive-ins and

958
00:49:31,019 --> 00:49:28,539
dives every now and then everything

959
00:49:33,210 --> 00:49:31,029
Italian just to sort of watch other

960
00:49:34,740 --> 00:49:33,220
people make some good food and just some

961
00:49:36,960 --> 00:49:34,750
some funny shows like that and sometimes

962
00:49:38,940 --> 00:49:36,970
the news you know we watched actually

963
00:49:40,230 --> 00:49:38,950
the Olympics while we were up there for

964
00:49:41,640 --> 00:49:40,240
part of the time we would get the

965
00:49:44,339 --> 00:49:41,650
highlights of the Olympics we watched

966
00:49:47,880 --> 00:49:44,349
part of the football season and as well

967
00:49:49,079 --> 00:49:47,890
on Sundays we also but you know you

968
00:49:50,460 --> 00:49:49,089
don't want to spend your time looking at

969
00:49:52,170 --> 00:49:50,470
a computer is that type of stuff while

970
00:49:53,789 --> 00:49:52,180
you're up in space so there's a lot of

971
00:49:55,500 --> 00:49:53,799
other cool things you can do you can do

972
00:49:57,450 --> 00:49:55,510
some of your own experiments with water

973
00:50:00,059 --> 00:49:57,460
or things that you brought up there

974
00:50:01,529 --> 00:50:00,069
I wrote a journal while I was there and

975
00:50:04,859 --> 00:50:01,539
of course looking out the window and

976
00:50:07,680 --> 00:50:04,869
taking pictures and talking to friends

977
00:50:09,750 --> 00:50:07,690
and family at home we have email as well

978
00:50:11,819 --> 00:50:09,760
as a phone that we're able to call home

979
00:50:13,319 --> 00:50:11,829
and talk to folks at home and wish

980
00:50:15,480 --> 00:50:13,329
people happy birthdays and stuff like

981
00:50:17,339 --> 00:50:15,490
that so we did spend a lot you know

982
00:50:22,500 --> 00:50:17,349
times trying to communicate with folks

983
00:50:26,620 --> 00:50:24,760
so a couple of things that you mentioned

984
00:50:27,700 --> 00:50:26,630
there are actually dovetail right into

985
00:50:29,620 --> 00:50:27,710
and one of our questions that we have

986
00:50:31,390 --> 00:50:29,630
from one of our Facebook users here so

987
00:50:32,620 --> 00:50:31,400
many days what kind of work did you do

988
00:50:33,640 --> 00:50:32,630
what experiments did you actually

989
00:50:38,860 --> 00:50:33,650
conduct while you were on the

990
00:50:41,380 --> 00:50:38,870
International Space Station so there was

991
00:50:43,960 --> 00:50:41,390
never a dull moment up or when we were

992
00:50:46,270 --> 00:50:43,970
there so we had EBA you know spacewalks

993
00:50:48,850 --> 00:50:46,280
so we had to prepare for it we had so

994
00:50:52,900 --> 00:50:48,860
many different visiting vehicles like

995
00:50:56,290 --> 00:50:52,910
the Japanese vehicle European the u.s.

996
00:50:59,590 --> 00:50:56,300
dragon vehicle and also a couple of

997
00:51:01,810 --> 00:50:59,600
progress vehicles from Russia and on top

998
00:51:05,530 --> 00:51:01,820
of that we did have a lot of different

999
00:51:07,180 --> 00:51:05,540
experiment you know medical science we

1000
00:51:12,250 --> 00:51:07,190
got to take our own blood and urine

1001
00:51:17,860 --> 00:51:12,260
samples we had like oh yeah that we had

1002
00:51:22,470 --> 00:51:17,870
got to uh look at our eyes using like

1003
00:51:26,740 --> 00:51:22,480
ultrasound and other stuff we did deploy

1004
00:51:28,780 --> 00:51:26,750
some satellites from station the Russian

1005
00:51:33,700 --> 00:51:28,790
side did it during their spacewalk

1006
00:51:36,130 --> 00:51:33,710
it was a huge sphere like maybe that big

1007
00:51:38,100 --> 00:51:36,140
and they they went outside with that

1008
00:51:40,630 --> 00:51:38,110
sphere and then they just tossed it out

1009
00:51:43,540 --> 00:51:40,640
they did it that way

1010
00:51:45,970 --> 00:51:43,550
we had another way of doing that on the

1011
00:51:48,700 --> 00:51:45,980
Japanese side we had a satellite

1012
00:51:51,820 --> 00:51:48,710
deployer which is like a just a box with

1013
00:51:53,770 --> 00:51:51,830
a spring at the end so you open the door

1014
00:51:56,680 --> 00:51:53,780
and then that spring force just pushes

1015
00:51:59,320 --> 00:51:56,690
out a small satellites outside so we did

1016
00:52:03,280 --> 00:51:59,330
it that way too and we had a couple of

1017
00:52:07,150 --> 00:52:03,290
creatures Sonny had spiders I had fishes

1018
00:52:09,370 --> 00:52:07,160
both for experiment for the fish we used

1019
00:52:15,610 --> 00:52:09,380
them to see the effect of microgravity

1020
00:52:18,460 --> 00:52:15,620
on bone density and muscle so they were

1021
00:52:22,000 --> 00:52:18,470
up there for two months and then B I

1022
00:52:23,890 --> 00:52:22,010
think they're all back down on earth so

1023
00:52:26,080 --> 00:52:23,900
the investigators will take a look at it

1024
00:52:28,240 --> 00:52:26,090
and compare with the fishes on the

1025
00:52:31,740 --> 00:52:28,250
ground and see if there's any any

1026
00:52:35,710 --> 00:52:33,880
wonderful we're going to go back to

1027
00:52:51,700 --> 00:52:35,720
Our Lady of Perpetual Help Catholic

1028
00:52:53,710 --> 00:52:51,710
school for the next question and our

1029
00:52:56,200 --> 00:52:53,720
question is what inspired you to become

1030
00:53:01,840 --> 00:52:56,210
an astronaut and what made you want to

1031
00:53:03,010 --> 00:53:01,850
be a scientist okay so hey you know I

1032
00:53:04,810 --> 00:53:03,020
didn't think about being an astronaut

1033
00:53:06,460 --> 00:53:04,820
till quite some time you know not

1034
00:53:08,350 --> 00:53:06,470
definitely not when I was your age I had

1035
00:53:11,080 --> 00:53:08,360
never met anybody who had been an

1036
00:53:13,270 --> 00:53:11,090
astronaut or actually really been in the

1037
00:53:14,590 --> 00:53:13,280
military except for my brother who went

1038
00:53:17,230 --> 00:53:14,600
to the Naval Academy a couple of years

1039
00:53:19,900 --> 00:53:17,240
before I did so I didn't really think

1040
00:53:22,690 --> 00:53:19,910
about it too much I I liked science and

1041
00:53:24,190 --> 00:53:22,700
math so engineering seemed to be a good

1042
00:53:26,800 --> 00:53:24,200
fit for me

1043
00:53:29,260 --> 00:53:26,810
so I went into general engineering and

1044
00:53:30,820 --> 00:53:29,270
went to the Naval Academy and started

1045
00:53:32,590 --> 00:53:30,830
flying helicopters right after that

1046
00:53:34,720 --> 00:53:32,600
still never thought about being an

1047
00:53:36,940 --> 00:53:34,730
astronaut until I had the opportunity to

1048
00:53:40,930 --> 00:53:36,950
go down to Johnson Space Center and meet

1049
00:53:44,140 --> 00:53:40,940
John Young who happily happened to have

1050
00:53:47,020 --> 00:53:44,150
flown a vertical landing type of space

1051
00:53:48,610 --> 00:53:47,030
aircraft to practice landing on the moon

1052
00:53:50,560 --> 00:53:48,620
and I thought wow well I'm doing that

1053
00:53:51,790 --> 00:53:50,570
flying helicopter so maybe I had the

1054
00:53:54,280 --> 00:53:51,800
same type of skills that some of these

1055
00:53:56,080 --> 00:53:54,290
guys have because I wanted to go back to

1056
00:53:58,840 --> 00:53:56,090
the moon and land on the moon so it

1057
00:54:00,430 --> 00:53:58,850
wasn't until later on in my life that I

1058
00:54:04,630 --> 00:54:00,440
thought wow maybe I could be an

1059
00:54:07,060 --> 00:54:04,640
astronaut science I love science it's it

1060
00:54:09,580 --> 00:54:07,070
came somewhat natural to me my dad was a

1061
00:54:11,530 --> 00:54:09,590
doctor and a research scientist so he

1062
00:54:13,360 --> 00:54:11,540
used to take us to his laboratory when

1063
00:54:15,070 --> 00:54:13,370
we were young kids and we looked through

1064
00:54:17,290 --> 00:54:15,080
the electron microscope and I think I

1065
00:54:21,310 --> 00:54:17,300
was having a curious mind in questioning

1066
00:54:22,330 --> 00:54:21,320
why and how does that work is is one of

1067
00:54:24,640 --> 00:54:22,340
those things that sort of came naturally

1068
00:54:26,500 --> 00:54:24,650
and or and actually maybe even just

1069
00:54:29,710 --> 00:54:26,510
taught because I think I heard it quite

1070
00:54:31,900 --> 00:54:29,720
a bit from my dad and his friends so I

1071
00:54:33,820 --> 00:54:31,910
would encourage all of you to do that

1072
00:54:35,620 --> 00:54:33,830
and I think when you start probing in

1073
00:54:37,480 --> 00:54:35,630
for the answers you might not always

1074
00:54:39,490 --> 00:54:37,490
find a satisfactory answer one that you

1075
00:54:41,800 --> 00:54:39,500
understand so I keep asking the question

1076
00:54:45,750 --> 00:54:41,810
and again and I'll bet you you will

1077
00:54:52,180 --> 00:54:50,770
thank you.thank wonderful we've got time

1078
00:54:56,220 --> 00:54:52,190
for just a couple more questions here

1079
00:55:01,030 --> 00:54:56,230
our next question comes from Facebook

1080
00:55:02,410 --> 00:55:01,040
from Theresa the Minsky Meijer sunny I

1081
00:55:03,790 --> 00:55:02,420
was wondering if your body felt it's

1082
00:55:06,250 --> 00:55:03,800
only after running the Boston Marathon

1083
00:55:07,570 --> 00:55:06,260
in space as it would on the ground for

1084
00:55:11,410 --> 00:55:07,580
instance did you have the same kind of

1085
00:55:13,750 --> 00:55:11,420
muscle soreness you know that's a really

1086
00:55:16,360 --> 00:55:13,760
interesting question because running on

1087
00:55:18,310 --> 00:55:16,370
the treadmill up there as I was building

1088
00:55:19,810 --> 00:55:18,320
up toward the marathon I didn't and I

1089
00:55:21,550 --> 00:55:19,820
was thinking to myself wow this is

1090
00:55:25,240 --> 00:55:21,560
interesting I'm not really getting as

1091
00:55:27,250 --> 00:55:25,250
sore but then as I started doing some

1092
00:55:29,500 --> 00:55:27,260
longer runs which took like an hour to

1093
00:55:31,150 --> 00:55:29,510
two hours to three hours I was like oh

1094
00:55:33,460 --> 00:55:31,160
you know now I'm finally getting that

1095
00:55:36,160 --> 00:55:33,470
soreness the same one back again and I

1096
00:55:37,930 --> 00:55:36,170
think part of the process there is and

1097
00:55:40,180 --> 00:55:37,940
then let me just say one other thing too

1098
00:55:43,530 --> 00:55:40,190
when I finished the marathon I

1099
00:55:47,080 --> 00:55:43,540
definitely had particularly you know

1100
00:55:48,970 --> 00:55:47,090
soreness on my thighs typical of what

1101
00:55:51,220 --> 00:55:48,980
you get back on earth when you're

1102
00:55:52,960 --> 00:55:51,230
running a marathon but if white all of

1103
00:55:55,060 --> 00:55:52,970
that went away really quickly you know

1104
00:55:56,620 --> 00:55:55,070
here on earth after you run you have all

1105
00:55:58,240 --> 00:55:56,630
that lactic acid built up in your

1106
00:56:00,340 --> 00:55:58,250
muscles and then you're still walking

1107
00:56:02,410 --> 00:56:00,350
around and having to go upstairs and

1108
00:56:05,410 --> 00:56:02,420
things like that and so it really feels

1109
00:56:07,540 --> 00:56:05,420
like it hurts but in space automatically

1110
00:56:09,520 --> 00:56:07,550
right if it's running you're floating

1111
00:56:12,670 --> 00:56:09,530
again and so your muscles are recovering

1112
00:56:14,080 --> 00:56:12,680
really quickly and so actually I thought

1113
00:56:16,600 --> 00:56:14,090
to myself I'm never getting on that darn

1114
00:56:18,430 --> 00:56:16,610
treadmill again but by the next day my

1115
00:56:20,650 --> 00:56:18,440
muscles felt fine and I was able to get

1116
00:56:22,780 --> 00:56:20,660
right back on it again so I think the

1117
00:56:24,490 --> 00:56:22,790
recovery process of not having to keep

1118
00:56:26,980 --> 00:56:24,500
that pounding going like we do here on

1119
00:56:30,360 --> 00:56:26,990
earth helps you with with that quite a

1120
00:56:35,350 --> 00:56:32,500
wonderful our next question comes from

1121
00:56:37,510 --> 00:56:35,360
Twitter from jail Oakley what is the

1122
00:56:39,610 --> 00:56:37,520
danger of space junk is there a project

1123
00:56:41,530 --> 00:56:39,620
to map it what kind of danger does it

1124
00:56:45,310 --> 00:56:41,540
pose to Earth in any way of future space

1125
00:56:48,310 --> 00:56:45,320
flights well there's a lot of garbage

1126
00:56:51,880 --> 00:56:48,320
around earth right now if those are from

1127
00:56:55,420 --> 00:56:51,890
like rockets dead satellites and a lot

1128
00:56:58,480 --> 00:56:55,430
of other things but for a space station

1129
00:56:59,650 --> 00:56:58,490
we're kind of tracking something which

1130
00:57:03,039 --> 00:56:59,660
is larger than

1131
00:57:05,470 --> 00:57:03,049
or inches and that's from the ground so

1132
00:57:08,140 --> 00:57:05,480
we know the trajectory and if that

1133
00:57:11,559 --> 00:57:08,150
coincides with the station's trajectory

1134
00:57:14,890 --> 00:57:11,569
we know ahead of time usually and we

1135
00:57:16,750 --> 00:57:14,900
will know that hey if we go on this path

1136
00:57:19,299 --> 00:57:16,760
we're gonna hit it or they're gonna hit

1137
00:57:22,990 --> 00:57:19,309
it hit us so what we do in that case is

1138
00:57:26,230 --> 00:57:23,000
we burn our engine a little bit so that

1139
00:57:31,049 --> 00:57:26,240
we change our ltitude and then that way

1140
00:57:32,410 --> 00:57:31,059
it will miss us now if it's smaller than

1141
00:57:35,230 --> 00:57:32,420
half an inch

1142
00:57:37,359 --> 00:57:35,240
one centimeter and it's not gonna

1143
00:57:39,760 --> 00:57:37,369
penetrate the whole of the station so

1144
00:57:43,180 --> 00:57:39,770
it's designed that way so that it's

1145
00:57:45,339 --> 00:57:43,190
protected now the problem is the size

1146
00:57:47,260 --> 00:57:45,349
between that so 1 centimeters to 10

1147
00:57:50,440 --> 00:57:47,270
centimeters you can't detect it you

1148
00:57:52,930 --> 00:57:50,450
can't you can't watch where it's going

1149
00:57:55,920 --> 00:57:52,940
and if it hit station then it's gonna

1150
00:58:00,069 --> 00:57:55,930
make a hole so what do we do the

1151
00:58:02,859 --> 00:58:00,079
probability is very low but we do train

1152
00:58:04,599 --> 00:58:02,869
for the worst case so if it hits we're

1153
00:58:07,420 --> 00:58:04,609
going to have depressurization onboard

1154
00:58:10,000 --> 00:58:07,430
the space station so we are trained we

1155
00:58:12,339 --> 00:58:10,010
have procedures we're trained on the

1156
00:58:14,710 --> 00:58:12,349
onboard as well as all the flight

1157
00:58:18,490 --> 00:58:14,720
controllers on the ground they are

1158
00:58:20,980 --> 00:58:18,500
trained and we we do train together in

1159
00:58:26,109 --> 00:58:20,990
some cases so we know what to do to save

1160
00:58:27,910 --> 00:58:26,119
ourselves wonderful this is gonna be our

1161
00:58:29,589 --> 00:58:27,920
final question for this Google+ hangout

1162
00:58:33,339 --> 00:58:29,599
here this comes from Twitter user Mike's

1163
00:58:35,559 --> 00:58:33,349
0-3 what role could the ISS play on the

1164
00:58:40,150 --> 00:58:35,569
future of human space travel including a

1165
00:58:42,339 --> 00:58:40,160
manned Mars mission well the space

1166
00:58:45,069 --> 00:58:42,349
station is a really great platform right

1167
00:58:54,320 --> 00:58:45,079
now because it's sort of a testbed we

1168
00:58:59,640 --> 00:58:57,960
but we try out all sorts of interesting

1169
00:59:02,490 --> 00:58:59,650
experiments like you guys talked about

1170
00:59:14,040 --> 00:59:02,500
capillary flow experiments to hopefully

1171
00:59:17,940 --> 00:59:14,050
design better fuel tanks for future

1172
00:59:19,740 --> 00:59:17,950
spacecraft all the material science we

1173
00:59:21,360 --> 00:59:19,750
actually did some burning science up

1174
00:59:23,340 --> 00:59:21,370
there where we burn different materials

1175
00:59:25,260 --> 00:59:23,350
to try to figure out how to build a

1176
00:59:27,840 --> 00:59:25,270
spacecraft that may be in microgravity

1177
00:59:31,200 --> 00:59:27,850
won't burn so we're using the space

1178
00:59:32,880 --> 00:59:31,210
station right now as a testbed for all

1179
00:59:36,210 --> 00:59:32,890
of these different pieces and parts that

1180
00:59:38,610 --> 00:59:36,220
will get smarter and on or make it more

1181
00:59:39,900 --> 00:59:38,620
efficient more better the things that

1182
00:59:42,750 --> 00:59:39,910
we're learning to make a better better

1183
00:59:45,270 --> 00:59:42,760
smarter spacecraft for you guys in the

1184
00:59:48,270 --> 00:59:45,280
future now a space station also could be

1185
00:59:50,430 --> 00:59:48,280
a platform we try out new spacecraft as

1186
00:59:51,720 --> 00:59:50,440
well we're actually moving some modules

1187
00:59:54,240 --> 00:59:51,730
around or we're planning to in the

1188
00:59:56,880 --> 00:59:54,250
future to provide more docking ports for

1189
01:00:00,090 --> 00:59:56,890
more potentially experimental type of

1190
01:00:01,290 --> 01:00:00,100
spacecraft to come up and join us on top

1191
01:00:03,990 --> 01:00:01,300
of that I think there's a the

1192
01:00:06,570 --> 01:00:04,000
international cooperation aspect right

1193
01:00:08,490 --> 01:00:06,580
now US Russia European countries Canada

1194
01:00:12,150 --> 01:00:08,500
and Japan are cooperating for the

1195
01:00:14,730 --> 01:00:12,160
international space station the space

1196
01:00:17,070 --> 01:00:14,740
station program will end eventually but

1197
01:00:19,980 --> 01:00:17,080
that cooperation that relationship the

1198
01:00:23,190 --> 01:00:19,990
partnership that will go on to the next

1199
01:00:29,490 --> 01:00:23,200
space program so we can help out each

1200
01:00:31,440 --> 01:00:29,500
other and that's in that way - wonderful

1201
01:00:33,000 --> 01:00:31,450
thank you very much for taking time to

1202
01:00:34,440 --> 01:00:33,010
sit down and answer all of these

1203
01:00:36,390 --> 01:00:34,450
questions today thank you to the two

1204
01:00:38,580 --> 01:00:36,400
schools for joining us and so on this

1205
01:00:40,380 --> 01:00:38,590
concludes today's Google+ hangout for

1206
01:00:42,960 --> 01:00:40,390
more information about the space station

1207
01:00:44,700 --> 01:00:42,970
research in low-earth orbit NASA's

1208
01:00:52,160 --> 01:00:44,710
