1
00:00:08,390 --> 00:00:05,510
um we're uh pleased to join you guys in

2
00:00:10,709 --> 00:00:08,400
phoenix from here inside the room and

3
00:00:12,950 --> 00:00:10,719
and luckily i'm joined by uh astronaut

4
00:00:15,509 --> 00:00:12,960
al drew who's got a lot of experience up

5
00:00:17,830 --> 00:00:15,519
in space he's been uh he's been in space

6
00:00:20,310 --> 00:00:17,840
twice he's flown on two space shuttle

7
00:00:22,150 --> 00:00:20,320
missions uh to that international space

8
00:00:24,790 --> 00:00:22,160
station uh sts

9
00:00:26,950 --> 00:00:24,800
118 and sts-133

10
00:00:28,870 --> 00:00:26,960
uh once uh aboard space shuttle

11
00:00:31,830 --> 00:00:28,880
endeavour and then he also flew on the

12
00:00:33,590 --> 00:00:31,840
last flight of discovery before it was

13
00:00:35,910 --> 00:00:33,600
retired along with the other two space

14
00:00:38,549 --> 00:00:35,920
shuttles so al has a tremendous amount

15
00:00:40,389 --> 00:00:38,559
of experience in space flight and and

16
00:00:42,069 --> 00:00:40,399
knows what life is like on board the

17
00:00:43,990 --> 00:00:42,079
international space station and in fact

18
00:00:45,910 --> 00:00:44,000
here in the flight control room he

19
00:00:46,950 --> 00:00:45,920
supported flights from in here as well

20
00:00:49,350 --> 00:00:46,960
so

21
00:00:52,150 --> 00:00:49,360
welcome phoenix and monterey park we're

22
00:00:54,549 --> 00:00:52,160
happy to be with you guys

23
00:00:57,189 --> 00:00:54,559
we're happy to have you as our guest

24
00:00:59,510 --> 00:00:57,199
today thank you so much for your time

25
00:01:01,189 --> 00:00:59,520
and liberty here

26
00:01:03,349 --> 00:01:01,199
is the first person that is going to be

27
00:01:04,630 --> 00:01:03,359
asking you a question

28
00:01:08,630 --> 00:01:04,640
okay

29
00:01:10,950 --> 00:01:08,640
um what um sports do you play in space

30
00:01:13,590 --> 00:01:10,960
what sports do you play in space uh

31
00:01:15,270 --> 00:01:13,600
let's see we have a basketball hoop on

32
00:01:16,550 --> 00:01:15,280
board the space station

33
00:01:18,149 --> 00:01:16,560
most of our europeans come up with

34
00:01:19,590 --> 00:01:18,159
soccer balls it's very easy to make

35
00:01:21,590 --> 00:01:19,600
bicycle kicks when you're on board the

36
00:01:33,830 --> 00:01:21,600
space station as well

37
00:01:37,910 --> 00:01:36,310
do you have access to the

38
00:01:39,030 --> 00:01:37,920
social media

39
00:01:41,270 --> 00:01:39,040
online

40
00:01:43,510 --> 00:01:41,280
video games

41
00:01:45,510 --> 00:01:43,520
yes we do we actually um in the past few

42
00:01:47,510 --> 00:01:45,520
years have gotten live internet on board

43
00:01:49,990 --> 00:01:47,520
the space station so we can

44
00:01:51,590 --> 00:01:50,000
access facebook and twitter i don't know

45
00:01:52,950 --> 00:01:51,600
if anybody who plays the video games i

46
00:01:55,030 --> 00:01:52,960
didn't see anybody was up there doing at

47
00:01:56,789 --> 00:01:55,040
the time but that may be because we're a

48
00:01:58,389 --> 00:01:56,799
little bit too old for that i'm sure

49
00:01:59,590 --> 00:01:58,399
that as we get newer and younger

50
00:02:01,670 --> 00:01:59,600
astronauts on they'll be playing things

51
00:02:10,389 --> 00:02:01,680
like world of warcraft on on the space

52
00:02:16,550 --> 00:02:12,869
do you get scared every time when you

53
00:02:18,150 --> 00:02:16,560
board into the spacecraft

54
00:02:19,670 --> 00:02:18,160
do you get scared yes there's an element

55
00:02:21,030 --> 00:02:19,680
of danger involved with spacecraft

56
00:02:22,790 --> 00:02:21,040
anybody who's not a little bit worried

57
00:02:24,550 --> 00:02:22,800
about that probably doesn't understand

58
00:02:26,550 --> 00:02:24,560
what's going on there's a lot of energy

59
00:02:28,949 --> 00:02:26,560
involved with getting yourself to earth

60
00:02:30,550 --> 00:02:28,959
orbit you're going 25 times the speed of

61
00:02:31,990 --> 00:02:30,560
sound that's about

62
00:02:34,309 --> 00:02:32,000
whole

63
00:02:36,229 --> 00:02:34,319
12 times faster than a speeding bullet

64
00:02:37,670 --> 00:02:36,239
and so it's a lot of energy has to go

65
00:02:39,350 --> 00:02:37,680
into that and so

66
00:02:40,949 --> 00:02:39,360
it's a good thing it makes us very

67
00:02:42,309 --> 00:02:40,959
careful and very safe and we pay a lot

68
00:02:44,390 --> 00:02:42,319
of attention to what we're doing when

69
00:02:46,070 --> 00:02:44,400
we're going to and from space and i

70
00:03:02,630 --> 00:02:46,080
think a little bit of anxiety helps you

71
00:03:07,350 --> 00:03:05,910
my question is how likely does space

72
00:03:11,430 --> 00:03:07,360
elevator

73
00:03:13,270 --> 00:03:11,440
i think it's likely the question more is

74
00:03:14,630 --> 00:03:13,280
when do we get a space elevator not will

75
00:03:16,470 --> 00:03:14,640
we ever have one

76
00:03:18,710 --> 00:03:16,480
we worked out the physics of it a long

77
00:03:20,550 --> 00:03:18,720
time ago it actually does work in theory

78
00:03:22,470 --> 00:03:20,560
however it takes some very strong

79
00:03:23,670 --> 00:03:22,480
materials to build that space elevator i

80
00:03:24,789 --> 00:03:23,680
don't think we have those materials

81
00:03:26,869 --> 00:03:24,799
quite yet

82
00:03:28,550 --> 00:03:26,879
but i think that we can get there at

83
00:03:45,190 --> 00:03:28,560
some point i don't think it's anywhere

84
00:03:47,750 --> 00:03:46,630
hi i'm steve

85
00:03:50,630 --> 00:03:47,760
how

86
00:03:51,990 --> 00:03:50,640
long does travel time to the space

87
00:03:54,149 --> 00:03:52,000
station

88
00:03:55,670 --> 00:03:54,159
how long does it take to get into space

89
00:03:57,350 --> 00:03:55,680
uh for if you're on a charlotte takes

90
00:03:58,710 --> 00:03:57,360
about eight and a half minutes and so

91
00:03:59,589 --> 00:03:58,720
think about that you're sitting on the

92
00:04:01,350 --> 00:03:59,599
ground

93
00:04:04,149 --> 00:04:01,360
at zero feet of altitude rating right at

94
00:04:05,589 --> 00:04:04,159
sea level doing zero miles per hour

95
00:04:09,030 --> 00:04:05,599
and eight and a half minutes later you

96
00:04:10,710 --> 00:04:09,040
are 100 miles up going at 17 500 miles

97
00:04:12,149 --> 00:04:10,720
per hour uh so it makes for a very

98
00:04:14,149 --> 00:04:12,159
exciting eight and a half minute ride

99
00:04:16,069 --> 00:04:14,159
yeah he also asked how long does it take

100
00:04:18,150 --> 00:04:16,079
to get to the space station too so in

101
00:04:19,909 --> 00:04:18,160
addition to that okay so once we get to

102
00:04:21,189 --> 00:04:19,919
space um there's the trekking into the

103
00:04:22,550 --> 00:04:21,199
space station now if we really needed to

104
00:04:24,390 --> 00:04:22,560
get there very very quickly which we

105
00:04:25,830 --> 00:04:24,400
don't typically uh it wouldn't take much

106
00:04:28,390 --> 00:04:25,840
longer to get to the space station maybe

107
00:04:30,150 --> 00:04:28,400
another 45 minutes however because the

108
00:04:31,590 --> 00:04:30,160
way we do our rendezvous we don't like

109
00:04:32,550 --> 00:04:31,600
just run to the space station and stand

110
00:04:34,550 --> 00:04:32,560
on the brakes because you don't want to

111
00:04:36,070 --> 00:04:34,560
hit the space station so we usually will

112
00:04:37,749 --> 00:04:36,080
spend a couple of days getting the space

113
00:04:39,670 --> 00:04:37,759
station going through checkouts making

114
00:04:41,189 --> 00:04:39,680
sure our spacecraft works okay

115
00:04:42,629 --> 00:04:41,199
but when it's time to come back from the

116
00:04:45,189 --> 00:04:42,639
space station when it comes time to land

117
00:04:47,110 --> 00:04:45,199
by the time we undock within an hour and

118
00:04:54,550 --> 00:04:47,120
a half we're back on the ground

119
00:04:59,350 --> 00:04:56,870
hi my name is michael and my question is

120
00:05:00,870 --> 00:04:59,360
how often do you travel to space

121
00:05:02,790 --> 00:05:00,880
questions how often do you travel to

122
00:05:04,710 --> 00:05:02,800
space depends on the astronaut depends

123
00:05:06,629 --> 00:05:04,720
on the time you're here

124
00:05:07,990 --> 00:05:06,639
it typically

125
00:05:09,189 --> 00:05:08,000
when things are very very busy when

126
00:05:10,870 --> 00:05:09,199
during this time of the space shuttle

127
00:05:13,990 --> 00:05:10,880
program you could count on going into

128
00:05:15,990 --> 00:05:14,000
space about once every two to four years

129
00:05:17,830 --> 00:05:16,000
with the shuttle retired and going to

130
00:05:19,990 --> 00:05:17,840
the space station the training alone

131
00:05:21,029 --> 00:05:20,000
takes anywhere between two and a half to

132
00:05:23,590 --> 00:05:21,039
four years depending on what you're

133
00:05:25,430 --> 00:05:23,600
training for so it would probably maybe

134
00:05:27,189 --> 00:05:25,440
even five years now between space

135
00:05:35,430 --> 00:05:27,199
station missions uh if you're on one of

136
00:05:42,150 --> 00:05:38,790
hi my name is d'angelo and how do you

137
00:05:43,830 --> 00:05:42,160
manage waste in space hi deangelo that's

138
00:05:45,029 --> 00:05:43,840
a very important question one of the

139
00:05:47,189 --> 00:05:45,039
things that you don't think about is the

140
00:05:48,390 --> 00:05:47,199
fact that when you're in space

141
00:05:50,390 --> 00:05:48,400
first off

142
00:05:52,150 --> 00:05:50,400
getting things is tough to do you can't

143
00:05:53,430 --> 00:05:52,160
run down to your local store and get

144
00:05:54,469 --> 00:05:53,440
groceries or go to the hardware store

145
00:05:55,909 --> 00:05:54,479
and get replaced so you have to bring

146
00:05:57,110 --> 00:05:55,919
everything up there with you and

147
00:05:58,230 --> 00:05:57,120
everything you get rid of there's no

148
00:05:59,670 --> 00:05:58,240
garbage truck that comes by every

149
00:06:00,550 --> 00:05:59,680
tuesday and thursday and takes away your

150
00:06:02,309 --> 00:06:00,560
stuff

151
00:06:03,749 --> 00:06:02,319
so but we do have garbage trucks there

152
00:06:05,909 --> 00:06:03,759
to the space station

153
00:06:08,150 --> 00:06:05,919
the progress capsules take away most of

154
00:06:10,950 --> 00:06:08,160
our garbage right now and we it burns up

155
00:06:13,029 --> 00:06:10,960
in the atmosphere so it i think every

156
00:06:14,629 --> 00:06:13,039
90 days or so a new progress comes in so

157
00:06:16,950 --> 00:06:14,639
we'll unpack it it has all of our fresh

158
00:06:18,629 --> 00:06:16,960
groceries and supplies and as soon as

159
00:06:20,550 --> 00:06:18,639
we've got it empty we start putting all

160
00:06:22,870 --> 00:06:20,560
of our old trash in there and when the

161
00:06:26,629 --> 00:06:22,880
new one comes up we undock it and we let

162
00:06:33,270 --> 00:06:27,749
thank you

163
00:06:33,280 --> 00:06:36,629
where do you get water

164
00:06:39,350 --> 00:06:38,469
uh water that's another very important

165
00:06:41,590 --> 00:06:39,360
question

166
00:06:43,510 --> 00:06:41,600
because uh it's probably the most

167
00:06:45,510 --> 00:06:43,520
important thing we have on space station

168
00:06:47,430 --> 00:06:45,520
that's a resource if we didn't have a

169
00:06:49,430 --> 00:06:47,440
reason a regular supply of anything if

170
00:06:50,870 --> 00:06:49,440
all of our supplies stopped today nobody

171
00:06:52,230 --> 00:06:50,880
took anything else up there

172
00:06:53,749 --> 00:06:52,240
probably the first thing we would run

173
00:06:55,189 --> 00:06:53,759
out of would be water even before we'd

174
00:06:56,790 --> 00:06:55,199
run out of air

175
00:06:58,469 --> 00:06:56,800
and so water is very important to all of

176
00:06:59,830 --> 00:06:58,479
us when we have just

177
00:07:02,070 --> 00:06:59,840
offices full of people here at johnson

178
00:07:03,110 --> 00:07:02,080
space center who watch our water budgets

179
00:07:05,110 --> 00:07:03,120
and figure out how we're going to get

180
00:07:07,029 --> 00:07:05,120
our water now again back in the days of

181
00:07:09,029 --> 00:07:07,039
the space station our fuel cells which

182
00:07:10,950 --> 00:07:09,039
made electricity for the space shuttle

183
00:07:13,110 --> 00:07:10,960
actually made hundreds of gallons of

184
00:07:14,710 --> 00:07:13,120
water as a waste product the clearest

185
00:07:17,270 --> 00:07:14,720
cleanest water you could possibly ever

186
00:07:19,029 --> 00:07:17,280
find would come out of these fuel cells

187
00:07:20,469 --> 00:07:19,039
and we would take them and pipe them

188
00:07:21,749 --> 00:07:20,479
over to the space station so that water

189
00:07:23,749 --> 00:07:21,759
was never an issue

190
00:07:25,510 --> 00:07:23,759
now we have the progress capsules and

191
00:07:27,270 --> 00:07:25,520
other resupply vehicles and they bring

192
00:07:28,950 --> 00:07:27,280
up tanks of water with them and we

193
00:07:31,510 --> 00:07:28,960
conserve our water but our life support

194
00:07:33,270 --> 00:07:31,520
systems now are much more miserly they

195
00:07:34,550 --> 00:07:33,280
we waste a lot less water used to be you

196
00:07:35,909 --> 00:07:34,560
know if you the water was dirty we

197
00:07:37,350 --> 00:07:35,919
didn't care much about recycling we

198
00:07:40,150 --> 00:07:37,360
would just dump the the dirty water

199
00:07:41,670 --> 00:07:40,160
overboard now we scrub and purify and

200
00:07:43,430 --> 00:07:41,680
recycle as much of that water as we

201
00:07:44,710 --> 00:07:43,440
possibly can because we don't have

202
00:07:50,629 --> 00:07:44,720
shuttles coming up every few weeks with

203
00:07:55,350 --> 00:07:51,830
thank you

204
00:08:01,110 --> 00:07:57,990
hi i'm brooklyn how do you guys keep

205
00:08:02,469 --> 00:08:01,120
yourself clean in space hi brooklyn uh

206
00:08:03,990 --> 00:08:02,479
keeping clean in space something very

207
00:08:08,150 --> 00:08:04,000
near and dear to my heart because i have

208
00:08:09,110 --> 00:08:08,160
spent a total of 26 days in space uh

209
00:08:10,790 --> 00:08:09,120
obviously the things you do on the

210
00:08:12,710 --> 00:08:10,800
ground here aren't don't quite work in

211
00:08:14,469 --> 00:08:12,720
space much of what you do in the

212
00:08:15,990 --> 00:08:14,479
bathroom the shower and what clean up

213
00:08:17,909 --> 00:08:16,000
needs gravity for the water to come

214
00:08:19,189 --> 00:08:17,919
across your body out of the spigot and

215
00:08:20,790 --> 00:08:19,199
go down the drain

216
00:08:21,990 --> 00:08:20,800
that doesn't work in space now any water

217
00:08:23,270 --> 00:08:22,000
you would shoot out of a nozzle would

218
00:08:25,270 --> 00:08:23,280
stay right there with you and along with

219
00:08:26,869 --> 00:08:25,280
the dirt that came off of you so

220
00:08:28,950 --> 00:08:26,879
rather than going to hop into a shower

221
00:08:30,629 --> 00:08:28,960
or a bathtub we take sponge baths if

222
00:08:32,310 --> 00:08:30,639
you've ever been camping you know what

223
00:08:33,750 --> 00:08:32,320
it's like to go out there and just get a

224
00:08:34,870 --> 00:08:33,760
towel or something wet and wipe yourself

225
00:08:36,790 --> 00:08:34,880
down

226
00:08:38,230 --> 00:08:36,800
clean that off and then rinse yourself

227
00:08:40,550 --> 00:08:38,240
off with another towel that have the

228
00:08:42,149 --> 00:08:40,560
soap on it and so it's very good at

229
00:08:44,070 --> 00:08:42,159
keeping you clean

230
00:08:45,590 --> 00:08:44,080
but not nearly as satisfying as say just

231
00:08:47,030 --> 00:08:45,600
a hot shower and you'll find most

232
00:08:48,230 --> 00:08:47,040
astronauts when they get back down the

233
00:08:49,910 --> 00:08:48,240
ground no matter how long they've been

234
00:08:51,670 --> 00:08:49,920
in space will go hop in the shower for

235
00:08:55,750 --> 00:08:51,680
30 to 45 minutes because they miss the

236
00:09:02,070 --> 00:08:55,760
sensation of just having a hot shower

237
00:09:06,389 --> 00:09:05,110
hello my name is jennifer hi jennifer my

238
00:09:08,389 --> 00:09:06,399
question is

239
00:09:10,949 --> 00:09:08,399
what is your favorite food

240
00:09:13,350 --> 00:09:10,959
what's my favorite food

241
00:09:15,430 --> 00:09:13,360
it depends from day to day

242
00:09:16,230 --> 00:09:15,440
well i'm here in in texas i like a lot

243
00:09:17,910 --> 00:09:16,240
of

244
00:09:19,910 --> 00:09:17,920
cajun food things like gumbo but also

245
00:09:21,190 --> 00:09:19,920
like barbecue and imagine if i live

246
00:09:22,630 --> 00:09:21,200
somewhere else i would eat something

247
00:09:24,470 --> 00:09:22,640
else differently but that's what they

248
00:09:26,870 --> 00:09:24,480
make best around here and they do a very

249
00:09:28,790 --> 00:09:26,880
good job of it what about

250
00:09:30,550 --> 00:09:28,800
yeah that's a good question because

251
00:09:32,710 --> 00:09:30,560
we've always heard that in space your

252
00:09:34,389 --> 00:09:32,720
taste buds tend to change

253
00:09:36,550 --> 00:09:34,399
what do you have a favorite food when

254
00:09:38,070 --> 00:09:36,560
you're flying can shift in space

255
00:09:39,110 --> 00:09:38,080
now some people debate that they say

256
00:09:41,750 --> 00:09:39,120
they've been in space and their tastes

257
00:09:43,190 --> 00:09:41,760
don't shift and for me my taste did

258
00:09:44,389 --> 00:09:43,200
shift on my first mission but it wasn't

259
00:09:45,829 --> 00:09:44,399
consistent didn't happen again on my

260
00:09:47,350 --> 00:09:45,839
second mission

261
00:09:48,630 --> 00:09:47,360
one of the things on space when i was in

262
00:09:51,509 --> 00:09:48,640
my shuttle mission

263
00:09:53,670 --> 00:09:51,519
we had these string beans with mushrooms

264
00:09:55,269 --> 00:09:53,680
and i eat string beans i don't hate

265
00:09:57,030 --> 00:09:55,279
string beans but i probably wouldn't go

266
00:09:58,389 --> 00:09:57,040
five steps out of my way to get a bowl

267
00:09:59,430 --> 00:09:58,399
of string beans anywhere on your earth i

268
00:10:00,230 --> 00:09:59,440
know they're good for me that's why i

269
00:10:02,150 --> 00:10:00,240
eat them

270
00:10:03,990 --> 00:10:02,160
uh i craved string beans when i was on

271
00:10:06,230 --> 00:10:04,000
orbit and i was trading away all my beef

272
00:10:07,590 --> 00:10:06,240
jerky which i love here on earth to get

273
00:10:09,190 --> 00:10:07,600
all the string beans that i could

274
00:10:10,389 --> 00:10:09,200
possibly get my hands on to us so i

275
00:10:12,310 --> 00:10:10,399
pretty much ate the entire shuttle

276
00:10:13,590 --> 00:10:12,320
supply of string beans in order to get

277
00:10:14,870 --> 00:10:13,600
them all and when i went back the second

278
00:10:17,269 --> 00:10:14,880
time i thought i'd crave them again and

279
00:10:20,150 --> 00:10:17,279
i didn't i didn't hate them but but they

280
00:10:21,910 --> 00:10:20,160
were just string beans at that point

281
00:10:23,590 --> 00:10:21,920
so who knows that's a science out there

282
00:10:25,110 --> 00:10:23,600
waiting to find out is why your taste

283
00:10:28,550 --> 00:10:25,120
might change on orbit and why they

284
00:10:28,560 --> 00:10:35,110
thank you

285
00:10:41,110 --> 00:10:37,670
hi my name is taitung

286
00:10:42,550 --> 00:10:41,120
my question is what hobbies do you have

287
00:10:45,670 --> 00:10:42,560
while in space

288
00:10:47,110 --> 00:10:45,680
so it just depends on

289
00:10:48,069 --> 00:10:47,120
the astronaut and how they're up how

290
00:10:49,750 --> 00:10:48,079
long they're up there if you're on a

291
00:10:51,829 --> 00:10:49,760
shuttle crew there's not much time for

292
00:10:52,870 --> 00:10:51,839
hobbies it's a very busy time you're

293
00:10:54,470 --> 00:10:52,880
just running very quickly for the

294
00:10:55,990 --> 00:10:54,480
two-week mission that you're there the

295
00:10:57,829 --> 00:10:56,000
space station crews have a little bit

296
00:10:59,590 --> 00:10:57,839
more free time and they do take up

297
00:11:01,670 --> 00:10:59,600
hobbies probably the most popular hobby

298
00:11:03,030 --> 00:11:01,680
in space is taking pictures of the earth

299
00:11:04,790 --> 00:11:03,040
we spend a lot of time with just

300
00:11:05,910 --> 00:11:04,800
top-notch photography instructors and we

301
00:11:07,829 --> 00:11:05,920
have some of the best photography

302
00:11:09,190 --> 00:11:07,839
equipment you can imagine and one of the

303
00:11:12,230 --> 00:11:09,200
most interesting things to look at when

304
00:11:14,550 --> 00:11:12,240
you're up in space about 250 miles up is

305
00:11:16,790 --> 00:11:14,560
the planet beneath us looking at oceans

306
00:11:19,110 --> 00:11:16,800
and reefs and mountain ranges and

307
00:11:20,870 --> 00:11:19,120
volcanoes and hurricanes and everything

308
00:11:23,030 --> 00:11:20,880
else you can imagine that goes on here

309
00:11:24,470 --> 00:11:23,040
back on earth uh is photography now some

310
00:11:26,230 --> 00:11:24,480
people have built ships and bottles and

311
00:11:27,670 --> 00:11:26,240
they like also using playing with ham

312
00:11:29,030 --> 00:11:27,680
radios to talk to

313
00:11:30,790 --> 00:11:29,040
school children just like you from on

314
00:11:34,710 --> 00:11:30,800
the ground and so those are things that

315
00:11:34,720 --> 00:11:39,269
thank you

316
00:11:45,030 --> 00:11:43,190
hi my name is andrew and my question is

317
00:11:47,030 --> 00:11:45,040
what kind of pets do you think will

318
00:11:49,110 --> 00:11:47,040
survive in that environment

319
00:11:50,790 --> 00:11:49,120
hi andrew i think most pets would

320
00:11:53,590 --> 00:11:50,800
survive in space we've taken up all

321
00:11:55,269 --> 00:11:53,600
types of animals not as pets from mice

322
00:11:57,110 --> 00:11:55,279
and other things like that and they seem

323
00:11:58,389 --> 00:11:57,120
to work just fine like anybody they're a

324
00:11:59,750 --> 00:11:58,399
little bit disoriented when we first

325
00:12:01,750 --> 00:11:59,760
take them to orbit because there's no up

326
00:12:03,509 --> 00:12:01,760
or down um but one thing i noticed with

327
00:12:04,710 --> 00:12:03,519
the mice that we carried up with us was

328
00:12:06,310 --> 00:12:04,720
after about a day or two they were doing

329
00:12:07,430 --> 00:12:06,320
the same astronaut stupid astronaut

330
00:12:09,030 --> 00:12:07,440
tricks that we were doing you know

331
00:12:10,870 --> 00:12:09,040
running around bouncing off the edge of

332
00:12:12,230 --> 00:12:10,880
the cages and smacking each other in the

333
00:12:13,829 --> 00:12:12,240
head and just doing goofy things that

334
00:12:15,350 --> 00:12:13,839
you would do when you realize that how

335
00:12:16,710 --> 00:12:15,360
much fun it is being weightless so i

336
00:12:19,670 --> 00:12:16,720
think most pets would do just fine in

337
00:12:19,680 --> 00:12:22,870
thank you

338
00:12:28,949 --> 00:12:26,069
hi my name is gaia my question is

339
00:12:31,269 --> 00:12:28,959
what um type of physical activities do

340
00:12:32,470 --> 00:12:31,279
you do in space yeah good uh it's

341
00:12:34,470 --> 00:12:32,480
another very good question something

342
00:12:35,670 --> 00:12:34,480
that we do worry about now one of the

343
00:12:37,670 --> 00:12:35,680
things you remember in space when you're

344
00:12:38,870 --> 00:12:37,680
weightless is that just sitting in your

345
00:12:40,790 --> 00:12:38,880
chair or standing there like you are

346
00:12:42,710 --> 00:12:40,800
talking to me you're getting more of a

347
00:12:44,949 --> 00:12:42,720
workout than you would just floating in

348
00:12:46,470 --> 00:12:44,959
space i just think about your head has

349
00:12:48,870 --> 00:12:46,480
weight and your neck has to hold your

350
00:12:50,230 --> 00:12:48,880
head up uh your legs and your feet have

351
00:12:51,590 --> 00:12:50,240
to hold the rest of your body up just

352
00:12:53,990 --> 00:12:51,600
lifting up your arm you know just moving

353
00:12:55,590 --> 00:12:54,000
your arms takes effort

354
00:12:57,750 --> 00:12:55,600
and when you're in space those muscles

355
00:12:59,590 --> 00:12:57,760
don't work anymore and so what we find

356
00:13:01,350 --> 00:12:59,600
out is that after a few days in space

357
00:13:03,590 --> 00:13:01,360
your muscles begin to waste away because

358
00:13:05,430 --> 00:13:03,600
your body is efficient which is my

359
00:13:06,870 --> 00:13:05,440
codeword for saying very lazy it doesn't

360
00:13:08,710 --> 00:13:06,880
support things it doesn't have to and

361
00:13:10,069 --> 00:13:08,720
your bones start to dissolve away too

362
00:13:11,990 --> 00:13:10,079
because the bones are there to support

363
00:13:13,350 --> 00:13:12,000
the muscles so in order to keep that

364
00:13:14,389 --> 00:13:13,360
from happening because eventually you do

365
00:13:15,990 --> 00:13:14,399
come back to earth and you want to be

366
00:13:17,829 --> 00:13:16,000
able to walk around

367
00:13:19,829 --> 00:13:17,839
our astronauts will exercise for as much

368
00:13:22,069 --> 00:13:19,839
as two and a half hours a day and so

369
00:13:23,590 --> 00:13:22,079
they're on these weight lifting machines

370
00:13:25,110 --> 00:13:23,600
obviously weights don't work because

371
00:13:26,550 --> 00:13:25,120
it's weightless but you can have

372
00:13:28,389 --> 00:13:26,560
resistance machines that simulate those

373
00:13:31,110 --> 00:13:28,399
weights we have treadmills and we have

374
00:13:33,350 --> 00:13:31,120
bicycles as well so you can keep

375
00:13:34,470 --> 00:13:33,360
keep your heart pumping as well so you

376
00:13:35,509 --> 00:13:34,480
keep your physical conditioning while

377
00:13:36,870 --> 00:13:35,519
you're in space in fact a lot of

378
00:13:38,550 --> 00:13:36,880
astronauts come back in better shape

379
00:13:40,230 --> 00:13:38,560
from being in space than they do on the

380
00:13:41,590 --> 00:13:40,240
ground because they have scheduled two

381
00:13:46,150 --> 00:13:41,600
and a half hours time to work we don't

382
00:13:46,160 --> 00:13:50,790
thank you

383
00:13:54,949 --> 00:13:52,870
do you keep a greenhouse in the space

384
00:13:56,310 --> 00:13:54,959
station and how

385
00:13:58,230 --> 00:13:56,320
do we keep a greenhouse in the space

386
00:14:00,230 --> 00:13:58,240
station yes we do we have plant growth

387
00:14:02,230 --> 00:14:00,240
experiments and we grow things there

388
00:14:04,069 --> 00:14:02,240
with lights and hydroponics and all

389
00:14:06,550 --> 00:14:04,079
kinds of other things like that

390
00:14:08,230 --> 00:14:06,560
and so we we we've grown like radishes

391
00:14:09,189 --> 00:14:08,240
and we've actually i think even managed

392
00:14:11,189 --> 00:14:09,199
to eat some of those things that we've

393
00:14:12,710 --> 00:14:11,199
grown in space but everybody enjoys

394
00:14:14,389 --> 00:14:12,720
seems to enjoy doing gardening in space

395
00:14:16,550 --> 00:14:14,399
it's one of the better past times even

396
00:14:23,030 --> 00:14:16,560
if it's out this will be an experiment

397
00:14:23,040 --> 00:14:27,269
thank you you're welcome

398
00:14:32,150 --> 00:14:29,590
hi my name is fernando and my question

399
00:14:33,670 --> 00:14:32,160
is can you control gravity in your cabin

400
00:14:36,470 --> 00:14:33,680
the question is can you control grabbed

401
00:14:38,550 --> 00:14:36,480
in your cabin um theoretically yes in in

402
00:14:40,629 --> 00:14:38,560
practice we really don't what you can do

403
00:14:42,389 --> 00:14:40,639
is you can spin your cabin so it behaves

404
00:14:44,069 --> 00:14:42,399
like a centrifuge uh years ago we

405
00:14:45,910 --> 00:14:44,079
actually thought about putting a a

406
00:14:47,350 --> 00:14:45,920
centrifuge aboard the space station

407
00:14:48,870 --> 00:14:47,360
because one of the few things you can do

408
00:14:51,350 --> 00:14:48,880
in space that you can't do here on earth

409
00:14:53,110 --> 00:14:51,360
is simulate gravities that are between

410
00:14:55,269 --> 00:14:53,120
zero and one so earth is always at one

411
00:14:56,550 --> 00:14:55,279
gravity and only for brief periods of

412
00:14:58,790 --> 00:14:56,560
time maybe seconds if you're doing a

413
00:15:01,110 --> 00:14:58,800
parabola in space over the earth can you

414
00:15:03,189 --> 00:15:01,120
get yourself to less than one earth

415
00:15:05,110 --> 00:15:03,199
gravity in terms of force if you're in

416
00:15:06,550 --> 00:15:05,120
space then you've got no gravity acting

417
00:15:08,629 --> 00:15:06,560
on you because you're in free fall you

418
00:15:10,550 --> 00:15:08,639
can simulate half of earth's gravity you

419
00:15:12,310 --> 00:15:10,560
can simulate mars gravity which is about

420
00:15:14,470 --> 00:15:12,320
38 percent burst gravity or even moon's

421
00:15:16,710 --> 00:15:14,480
gravity or just one sixteen percent

422
00:15:18,310 --> 00:15:16,720
burst gravity and so you can control in

423
00:15:19,590 --> 00:15:18,320
that aspect but we don't have any means

424
00:15:22,389 --> 00:15:19,600
of doing that right now aboard our space

425
00:15:22,399 --> 00:15:26,470
thank you you're welcome

426
00:15:31,749 --> 00:15:28,230
hi my name is alex and i want to know

427
00:15:33,269 --> 00:15:31,759
how do you guys power the iss alex

428
00:15:34,790 --> 00:15:33,279
that's also a very good question one of

429
00:15:37,110 --> 00:15:34,800
the things that the way we power the

430
00:15:39,189 --> 00:15:37,120
international space station is by solar

431
00:15:40,629 --> 00:15:39,199
arrays you see those giant um

432
00:15:42,470 --> 00:15:40,639
rays you see out there though those

433
00:15:44,870 --> 00:15:42,480
eight of them out there um it's an acre

434
00:15:46,230 --> 00:15:44,880
of solar arrays and i think it

435
00:15:47,670 --> 00:15:46,240
gathers something in order of 80

436
00:15:49,670 --> 00:15:47,680
kilowatts of power and that's about

437
00:15:51,509 --> 00:15:49,680
enough that a city blocks worth of homes

438
00:15:53,910 --> 00:15:51,519
there in phoenix would use about 80

439
00:15:56,150 --> 00:15:53,920
kilowatts worth of power and so really

440
00:15:57,829 --> 00:15:56,160
our our power source is the sun and i

441
00:15:59,509 --> 00:15:57,839
remember when i was on the space shuttle

442
00:16:01,269 --> 00:15:59,519
we would go and plug into the space

443
00:16:02,389 --> 00:16:01,279
station and use their power and all

444
00:16:04,629 --> 00:16:02,399
those kind of giggles i thought we were

445
00:16:08,550 --> 00:16:04,639
stealing power from the sun onboard our

446
00:16:08,560 --> 00:16:13,590
thank you you're welcome

447
00:16:18,310 --> 00:16:16,310
hi my name is fernando and i want to

448
00:16:20,150 --> 00:16:18,320
know what is the possibility of space

449
00:16:21,430 --> 00:16:20,160
tourism in the future

450
00:16:22,629 --> 00:16:21,440
ah it's another good question the

451
00:16:24,790 --> 00:16:22,639
possibility of space tourism in the

452
00:16:26,389 --> 00:16:24,800
future well space tourism is now uh

453
00:16:27,829 --> 00:16:26,399
we've actually had a number of space

454
00:16:29,509 --> 00:16:27,839
tourists go to the international space

455
00:16:30,550 --> 00:16:29,519
station over the past few years i

456
00:16:32,230 --> 00:16:30,560
believe the russians are actually

457
00:16:34,310 --> 00:16:32,240
planning on carrying up a another space

458
00:16:35,910 --> 00:16:34,320
tourist in a few years from now and now

459
00:16:37,910 --> 00:16:35,920
they have some extra capacity on their

460
00:16:39,829 --> 00:16:37,920
line for the soyuz capsules here in

461
00:16:42,069 --> 00:16:39,839
america we have a number of companies

462
00:16:44,870 --> 00:16:42,079
building spacecraft specifically for

463
00:16:46,230 --> 00:16:44,880
space tourism uh they're just someone

464
00:16:47,590 --> 00:16:46,240
will take you in space for maybe four or

465
00:16:49,670 --> 00:16:47,600
five minutes where you can be weightless

466
00:16:50,710 --> 00:16:49,680
and float your m ms whatever you want to

467
00:16:52,790 --> 00:16:50,720
put out in front of you and get some

468
00:16:54,470 --> 00:16:52,800
pictures and be back on earth or you can

469
00:16:56,790 --> 00:16:54,480
actually have ones that will take you up

470
00:16:58,470 --> 00:16:56,800
for weeks in space in orbit and so i

471
00:17:00,230 --> 00:16:58,480
think by the time

472
00:17:01,670 --> 00:17:00,240
you're able to afford going into space

473
00:17:03,110 --> 00:17:01,680
we'll have lots of people out there

474
00:17:06,549 --> 00:17:03,120
willing to carry you up to space to go

475
00:17:06,559 --> 00:17:11,110
thank you you're welcome

476
00:17:15,429 --> 00:17:13,270
my name is liberty and

477
00:17:18,230 --> 00:17:15,439
another question i would like to ask how

478
00:17:20,630 --> 00:17:18,240
long do you think astronauts

479
00:17:21,829 --> 00:17:20,640
possibly live and work in space

480
00:17:23,189 --> 00:17:21,839
the question is how long do you think

481
00:17:24,789 --> 00:17:23,199
astronauts can live and work in space

482
00:17:26,710 --> 00:17:24,799
and that's something that's been on my

483
00:17:27,990 --> 00:17:26,720
mind for about the last year i've been

484
00:17:30,310 --> 00:17:28,000
working over in a program called the

485
00:17:32,070 --> 00:17:30,320
deep space habitat project and we've

486
00:17:34,710 --> 00:17:32,080
been thinking about you know taking

487
00:17:36,710 --> 00:17:34,720
spacecraft out to places like asteroids

488
00:17:38,310 --> 00:17:36,720
and even the planet mars and some of

489
00:17:40,789 --> 00:17:38,320
those missions are very long they can be

490
00:17:43,350 --> 00:17:40,799
as much as 900 to 1500 days away from

491
00:17:45,430 --> 00:17:43,360
the earth and so the question is like

492
00:17:47,750 --> 00:17:45,440
can people survive for that amount of

493
00:17:49,830 --> 00:17:47,760
time out there in space and if so what

494
00:17:51,590 --> 00:17:49,840
do we need to go about doing and so

495
00:17:53,750 --> 00:17:51,600
there's there's big challenges out there

496
00:17:56,070 --> 00:17:53,760
one of the bigger ones is radiation in

497
00:17:57,990 --> 00:17:56,080
deep space our earth and its atmosphere

498
00:17:59,830 --> 00:17:58,000
and its magnetic field protect us from a

499
00:18:01,430 --> 00:17:59,840
lot of radiation that comes from the

500
00:18:03,110 --> 00:18:01,440
center of our galaxy

501
00:18:04,549 --> 00:18:03,120
and so

502
00:18:06,310 --> 00:18:04,559
if we're going to go out beyond the

503
00:18:08,230 --> 00:18:06,320
earth's magnetic field

504
00:18:09,510 --> 00:18:08,240
we're going to be subject to radiation

505
00:18:11,350 --> 00:18:09,520
such that we probably wouldn't stay out

506
00:18:12,950 --> 00:18:11,360
there for more than six months right now

507
00:18:14,470 --> 00:18:12,960
without some type of shielding or ways

508
00:18:16,310 --> 00:18:14,480
of deflecting or maybe creating our own

509
00:18:17,669 --> 00:18:16,320
magnetic field another thing is

510
00:18:19,270 --> 00:18:17,679
weightlessness we know even with all of

511
00:18:20,789 --> 00:18:19,280
our exercises we're not doing things

512
00:18:23,350 --> 00:18:20,799
that stimulate our inner ear to give us

513
00:18:24,630 --> 00:18:23,360
balance and so that sense goes away and

514
00:18:26,150 --> 00:18:24,640
it takes a while the longer you're in

515
00:18:28,150 --> 00:18:26,160
space the longer it takes to bring that

516
00:18:30,710 --> 00:18:28,160
back so we may have to do things like

517
00:18:31,590 --> 00:18:30,720
bring about artificial gravity like one

518
00:18:33,590 --> 00:18:31,600
of your

519
00:18:35,270 --> 00:18:33,600
fellow classmates brought up so we can

520
00:18:37,190 --> 00:18:35,280
have some way of doing that

521
00:18:39,669 --> 00:18:37,200
food because we don't have a way to cook

522
00:18:41,590 --> 00:18:39,679
in zero g we have to prepare all food

523
00:18:43,430 --> 00:18:41,600
here in earth and basically make tv

524
00:18:45,110 --> 00:18:43,440
dinners out of them some of those new

525
00:18:46,710 --> 00:18:45,120
lose their nutrients after about a year

526
00:18:48,710 --> 00:18:46,720
and so they're not they didn't give you

527
00:18:51,110 --> 00:18:48,720
everything you need so that is how do we

528
00:18:52,230 --> 00:18:51,120
make food that keeps that nutrition or

529
00:18:53,590 --> 00:18:52,240
like let's see if somebody come up with

530
00:18:54,870 --> 00:18:53,600
a way of cooking in

531
00:18:56,950 --> 00:18:54,880
zero gravity you know go out there and

532
00:18:59,270 --> 00:18:56,960
just give me things like you know oats

533
00:19:00,870 --> 00:18:59,280
and flour and water and eggs and things

534
00:19:03,270 --> 00:19:00,880
like that and i can go whip up something

535
00:19:04,630 --> 00:19:03,280
right in my own kitchen there in zero g

536
00:19:06,310 --> 00:19:04,640
so those things we need to think about

537
00:19:07,909 --> 00:19:06,320
for keeping people in space but up to

538
00:19:10,630 --> 00:19:07,919
now up to date we've had a person in

539
00:19:12,789 --> 00:19:10,640
space for 400 days on that one order of

540
00:19:14,470 --> 00:19:12,799
that and you know in a short time we'll

541
00:19:16,549 --> 00:19:14,480
have another crew that will stay up on

542
00:19:18,390 --> 00:19:16,559
the space station for about a year

543
00:19:20,950 --> 00:19:18,400
so that's the limit right now is about a

544
00:19:22,789 --> 00:19:20,960
year and i think it'll take some new

545
00:19:24,070 --> 00:19:22,799
technologies for us to get along go in

546
00:19:25,750 --> 00:19:24,080
space longer than that especially deep

547
00:19:29,110 --> 00:19:25,760
space outside of the earth's magnetic

548
00:19:29,120 --> 00:19:34,230
thank you you're welcome

549
00:19:39,430 --> 00:19:37,270
my name is susan my question is

550
00:19:41,270 --> 00:19:39,440
what is your most unforgettable moment

551
00:19:43,110 --> 00:19:41,280
while living in space yeah great

552
00:19:44,710 --> 00:19:43,120
question good question susan that's

553
00:19:46,150 --> 00:19:44,720
that's also a very difficult question

554
00:19:48,390 --> 00:19:46,160
it's because there are a number of

555
00:19:49,510 --> 00:19:48,400
unforgettable moments in space but i'll

556
00:19:51,590 --> 00:19:49,520
share this one secret you can't tell

557
00:19:53,669 --> 00:19:51,600
anybody about this okay

558
00:19:55,510 --> 00:19:53,679
we were undocked from the international

559
00:19:57,430 --> 00:19:55,520
space station on the final flight of the

560
00:19:59,110 --> 00:19:57,440
space shuttle discovery and one of the

561
00:20:00,390 --> 00:19:59,120
things we have to do before we come in

562
00:20:02,149 --> 00:20:00,400
and land is

563
00:20:04,230 --> 00:20:02,159
use the robot arm and a camera to look

564
00:20:06,549 --> 00:20:04,240
for any holes that may have been

565
00:20:08,310 --> 00:20:06,559
poked into the into the orbiter by any

566
00:20:10,149 --> 00:20:08,320
debris that was floating around in space

567
00:20:11,029 --> 00:20:10,159
and so we had this camera it's a very

568
00:20:13,350 --> 00:20:11,039
slow

569
00:20:15,190 --> 00:20:13,360
and painstaking process while you look

570
00:20:16,710 --> 00:20:15,200
but it's very important to go do

571
00:20:17,990 --> 00:20:16,720
and so we're very methodical very

572
00:20:19,430 --> 00:20:18,000
disciplined anybody who's not part of it

573
00:20:20,950 --> 00:20:19,440
doesn't need to be on the flight deck

574
00:20:23,029 --> 00:20:20,960
and we go through this in a step-by-step

575
00:20:24,310 --> 00:20:23,039
process also very tiring so two people

576
00:20:26,310 --> 00:20:24,320
have to do it but three of us kind of

577
00:20:27,909 --> 00:20:26,320
rotate through and so i just got done

578
00:20:29,590 --> 00:20:27,919
with my half hour of

579
00:20:31,510 --> 00:20:29,600
helping out with this and i was just

580
00:20:34,149 --> 00:20:31,520
resting my eyes looking out the window

581
00:20:36,390 --> 00:20:34,159
and we were coming up on the west coast

582
00:20:38,310 --> 00:20:36,400
of australia over the indian ocean and i

583
00:20:39,830 --> 00:20:38,320
saw a faint green glow down beneath me

584
00:20:41,350 --> 00:20:39,840
and almost at the same tone of voice i'm

585
00:20:43,669 --> 00:20:41,360
talking right now it's like wow that

586
00:20:45,590 --> 00:20:43,679
looks like an aurora down there

587
00:20:47,110 --> 00:20:45,600
and almost immediately

588
00:20:48,950 --> 00:20:47,120
the commander and the pilot who were

589
00:20:50,149 --> 00:20:48,960
working the inspection stopped the arm

590
00:20:51,430 --> 00:20:50,159
and put a brakes on and they said did

591
00:20:53,510 --> 00:20:51,440
you say aurora and all the other crew

592
00:20:55,510 --> 00:20:53,520
members come flooding up from the mid

593
00:20:57,029 --> 00:20:55,520
the flight the mid deck and we've got

594
00:20:58,630 --> 00:20:57,039
cameras and we're in and usually we know

595
00:21:00,070 --> 00:20:58,640
we're very calm you've never seen apollo

596
00:21:01,750 --> 00:21:00,080
13 now you always have to be very calm

597
00:21:03,110 --> 00:21:01,760
about things and it's just it's just

598
00:21:04,230 --> 00:21:03,120
chaos you know we're screaming we're

599
00:21:05,190 --> 00:21:04,240
trying to find lenses we're trying to

600
00:21:06,950 --> 00:21:05,200
get the right angle we're trying to get

601
00:21:08,390 --> 00:21:06,960
the right exposure it was just madness

602
00:21:09,990 --> 00:21:08,400
for about five minutes then we get over

603
00:21:11,510 --> 00:21:10,000
the aurora and we get these breathtaking

604
00:21:12,950 --> 00:21:11,520
shots and then we're over top of

605
00:21:14,870 --> 00:21:12,960
australia and everybody kind of like

606
00:21:16,149 --> 00:21:14,880
goes the insanity prevailed again you

607
00:21:17,750 --> 00:21:16,159
know we kind of cleaned everything back

608
00:21:19,029 --> 00:21:17,760
up they went back down the mid deck they

609
00:21:20,789 --> 00:21:19,039
weren't doing the inspection and we went

610
00:21:22,070 --> 00:21:20,799
back to finishing inspecting the orbiter

611
00:21:23,350 --> 00:21:22,080
to go back in but that was it was a

612
00:21:25,029 --> 00:21:23,360
breathtaking moment to be over top

613
00:21:26,630 --> 00:21:25,039
there's just some

614
00:21:27,750 --> 00:21:26,640
rivers of green fire that were coming up

615
00:21:29,350 --> 00:21:27,760
from the atmosphere and we're just right

616
00:21:30,549 --> 00:21:29,360
over top of it looking down and as if

617
00:21:31,830 --> 00:21:30,559
even from the ground it's impressive

618
00:21:34,789 --> 00:21:31,840
it's even more impressive to be looking

619
00:21:36,470 --> 00:21:34,799
at it from above in space

620
00:21:39,190 --> 00:21:36,480
but you can't tell me about that anybody

621
00:21:39,200 --> 00:21:45,830
thank you you're welcome

622
00:21:51,909 --> 00:21:47,750
hi my name is david i'm going to ask a

623
00:21:55,669 --> 00:21:53,590
i'm sorry what is your

624
00:21:59,430 --> 00:21:55,679
most favorite site

625
00:22:01,190 --> 00:21:59,440
tell you that after going to space and

626
00:22:02,789 --> 00:22:01,200
looking back the earth is my most

627
00:22:04,470 --> 00:22:02,799
favorite site from space i'm just

628
00:22:05,669 --> 00:22:04,480
looking back on it it's just a beautiful

629
00:22:06,870 --> 00:22:05,679
thing to be near

630
00:22:08,390 --> 00:22:06,880
i've thought about what other planets

631
00:22:09,909 --> 00:22:08,400
i'd like to be above but none of them i

632
00:22:11,590 --> 00:22:09,919
think would be as interesting as the

633
00:22:13,270 --> 00:22:11,600
earth

634
00:22:15,350 --> 00:22:13,280
other planets no other planets i know

635
00:22:17,350 --> 00:22:15,360
have any real oceans the other ones have

636
00:22:19,270 --> 00:22:17,360
atmospheres and weather but this don't

637
00:22:20,470 --> 00:22:19,280
have the color and variety and just the

638
00:22:22,549 --> 00:22:20,480
different things that are out there that

639
00:22:24,310 --> 00:22:22,559
i think that earth does so it took me

640
00:22:26,390 --> 00:22:24,320
leaving the earth for two weeks at a

641
00:22:31,350 --> 00:22:26,400
time to really appreciate what a gym we

642
00:22:31,360 --> 00:22:37,270
thank you you're welcome

643
00:22:42,390 --> 00:22:40,070
hi my name is joey and i'm going to ask

644
00:22:45,190 --> 00:22:42,400
questions what are your top

645
00:22:46,470 --> 00:22:45,200
issues that you have to deal with in the

646
00:22:48,230 --> 00:22:46,480
space station

647
00:22:49,510 --> 00:22:48,240
well the top issues we have to deal with

648
00:22:50,710 --> 00:22:49,520
in the space station now again another

649
00:22:52,630 --> 00:22:50,720
very good question is the kind of things

650
00:22:53,830 --> 00:22:52,640
that that flight directors ask about so

651
00:22:55,590 --> 00:22:53,840
you sure you

652
00:22:58,070 --> 00:22:55,600
you're afraid to come down here and work

653
00:22:59,590 --> 00:22:58,080
for us flight director in training uh

654
00:23:01,830 --> 00:22:59,600
the top issues the main thing is that

655
00:23:03,830 --> 00:23:01,840
again we're isolated um and it's not so

656
00:23:06,630 --> 00:23:03,840
much by the distance we're only 250

657
00:23:08,230 --> 00:23:06,640
miles up in space which is probably

658
00:23:10,789 --> 00:23:08,240
less distance between you and the

659
00:23:13,510 --> 00:23:10,799
arizona state border however you're

660
00:23:15,430 --> 00:23:13,520
separated by speed 17 500 miles an hour

661
00:23:17,110 --> 00:23:15,440
is a incredibly fast speed so things

662
00:23:19,510 --> 00:23:17,120
just you just don't get there and back

663
00:23:21,750 --> 00:23:19,520
very quickly and so things like water

664
00:23:23,350 --> 00:23:21,760
and air and food and science everything

665
00:23:24,870 --> 00:23:23,360
out there has to be imported i mean

666
00:23:26,870 --> 00:23:24,880
there's really nothing up there in space

667
00:23:29,190 --> 00:23:26,880
you just can't step outside and grab

668
00:23:31,110 --> 00:23:29,200
what you need so that's probably the the

669
00:23:33,110 --> 00:23:31,120
top issue there

670
00:23:34,310 --> 00:23:33,120
the other part is because of that we

671
00:23:35,990 --> 00:23:34,320
we're pack rats you know you've seen

672
00:23:37,750 --> 00:23:36,000
these hoarding shows we we have our own

673
00:23:39,590 --> 00:23:37,760
hoarding problem on the city space space

674
00:23:41,590 --> 00:23:39,600
station because we're afraid of running

675
00:23:43,190 --> 00:23:41,600
out of things so you'll find that every

676
00:23:45,269 --> 00:23:43,200
nook and cranny in the space station is

677
00:23:47,430 --> 00:23:45,279
just crammed with something that we

678
00:23:49,990 --> 00:23:47,440
might need sooner or later and so as big

679
00:23:51,350 --> 00:23:50,000
and palatial as the space station is

680
00:23:53,350 --> 00:23:51,360
finding room for all that stuff is kind

681
00:23:54,950 --> 00:23:53,360
of a problem

682
00:24:06,630 --> 00:23:54,960
all right this is going to be our final

683
00:24:10,070 --> 00:24:08,470
hi my name is christian

684
00:24:13,909 --> 00:24:10,080
what is the

685
00:24:15,909 --> 00:24:13,919
what is next for nasa's space flights

686
00:24:17,510 --> 00:24:15,919
great question wow that's a that is a

687
00:24:19,510 --> 00:24:17,520
great question and

688
00:24:21,350 --> 00:24:19,520
this that is the 64 million dollar

689
00:24:24,070 --> 00:24:21,360
question what is next from nasa space

690
00:24:25,590 --> 00:24:24,080
flights um i said for the foreseeable

691
00:24:27,590 --> 00:24:25,600
future we will continue to operate the

692
00:24:28,870 --> 00:24:27,600
international space station which is

693
00:24:30,470 --> 00:24:28,880
like everything nasa has built

694
00:24:32,390 --> 00:24:30,480
incredibly over engineered and living

695
00:24:34,070 --> 00:24:32,400
long past when we thought it would and

696
00:24:35,990 --> 00:24:34,080
so we expect well into the next decade

697
00:24:37,990 --> 00:24:36,000
to be operating the space station

698
00:24:39,430 --> 00:24:38,000
our we expect to have more commercial

699
00:24:41,909 --> 00:24:39,440
partners onboard the international space

700
00:24:43,430 --> 00:24:41,919
station as some of our

701
00:24:45,830 --> 00:24:43,440
commercial like these commercial space

702
00:24:47,350 --> 00:24:45,840
operators get the capability to bring up

703
00:24:49,350 --> 00:24:47,360
crew members as well as cargo they're

704
00:24:50,789 --> 00:24:49,360
already bringing up cargo back and forth

705
00:24:52,230 --> 00:24:50,799
in the space station next world thing

706
00:24:53,190 --> 00:24:52,240
we'll see is our crew members going to

707
00:24:54,950 --> 00:24:53,200
and from the space station on these

708
00:24:56,870 --> 00:24:54,960
commercial vehicles and of course we're

709
00:24:59,350 --> 00:24:56,880
always thinking about interplanetary

710
00:25:01,269 --> 00:24:59,360
travel so we're looking at

711
00:25:02,149 --> 00:25:01,279
we go to asteroids that are near the

712
00:25:03,669 --> 00:25:02,159
earth

713
00:25:05,350 --> 00:25:03,679
and going of course i'm always thinking

714
00:25:06,630 --> 00:25:05,360
about the red planet that's the next

715
00:25:09,029 --> 00:25:06,640
place i'd like to go see us do in my

716
00:25:10,549 --> 00:25:09,039
lifetime so i think that's out there

717
00:25:11,909 --> 00:25:10,559
about the time that you get to sit in

718
00:25:14,070 --> 00:25:11,919
mission control and talk to students in

719
00:25:16,149 --> 00:25:14,080
phoenix that's will be you'll be talking

720
00:25:18,070 --> 00:25:16,159
