00:00:05,829 --> 00:00:03,750
ktrk tv this is mission control houston

2
00:00:08,549 --> 00:00:05,839
please call station 4 voice check

3
00:00:09,669 --> 00:00:08,559
station this is ktrk this can you hear

4
00:00:11,669 --> 00:00:09,679
me

5
00:00:17,430 --> 00:00:11,679
tv

6
00:00:17,440 --> 00:00:22,390
hi scott it's kevin quinn how you doing

7
00:00:22,400 --> 00:00:27,750
doing good kevin how are you

8
00:00:32,310 --> 00:00:30,070
i'm good i'm good let's talk a little

9
00:00:38,389 --> 00:00:32,320
bit about your mission this time so far

10
00:00:42,869 --> 00:00:41,030
you know it's uh it's interesting when i

11
00:00:44,470 --> 00:00:42,879
got on board the space station the one

12
00:00:46,150 --> 00:00:44,480
thing i noticed that was different than

13
00:00:48,150 --> 00:00:46,160
when i got on board last time is that i

14
00:00:50,470 --> 00:00:48,160
was much more comfortable here you know

15
00:00:53,189 --> 00:00:50,480
it's uh really amazing how your body

16
00:00:55,110 --> 00:00:53,199
remembers the environment uh how you

17
00:00:57,350 --> 00:00:55,120
move around well just how your you know

18
00:00:59,349 --> 00:00:57,360
your body systems

19
00:01:01,990 --> 00:00:59,359
you know remember being up here

20
00:01:04,950 --> 00:01:02,000
uh so that was different in a good way i

21
00:01:06,789 --> 00:01:04,960
was more comfortable

22
00:01:08,230 --> 00:01:06,799
but also a lot of things were the same

23
00:01:09,830 --> 00:01:08,240
you know it was interesting seeing how

24
00:01:13,590 --> 00:01:09,840
the space station

25
00:01:15,429 --> 00:01:13,600
by and large does not look like it aged

26
00:01:21,670 --> 00:01:15,439
four years since i was here last and

27
00:01:25,749 --> 00:01:23,749
a mission like this for a year in space

28
00:01:31,830 --> 00:01:25,759
do you have to take necessarily a

29
00:01:35,749 --> 00:01:34,149
yeah i do you know when i was here last

30
00:01:37,830 --> 00:01:35,759
time on a

31
00:01:38,710 --> 00:01:37,840
on a six month or around a six-month

32
00:01:40,390 --> 00:01:38,720
flight

33
00:01:42,069 --> 00:01:40,400
it's almost the type of thing where you

34
00:01:43,190 --> 00:01:42,079
can kind of see the end from the

35
00:01:46,149 --> 00:01:43,200
beginning

36
00:01:47,749 --> 00:01:46,159
and uh you know you you think about

37
00:01:50,069 --> 00:01:47,759
well you know i got through this month

38
00:01:51,109 --> 00:01:50,079
and i got you know four or five more to

39
00:01:52,149 --> 00:01:51,119
go

40
00:01:54,389 --> 00:01:52,159
um

41
00:01:57,190 --> 00:01:54,399
i don't think that way now and i i think

42
00:01:59,030 --> 00:01:57,200
it's um you know critical to me be able

43
00:02:00,950 --> 00:01:59,040
being able to function and work up here

44
00:02:02,789 --> 00:02:00,960
for a long period of time

45
00:02:04,870 --> 00:02:02,799
i just try to have the mindset that this

46
00:02:07,350 --> 00:02:04,880
is where i live now and uh you know

47
00:02:08,630 --> 00:02:07,360
someday in the future long in the future

48
00:02:09,589 --> 00:02:08,640
i'll leave

49
00:02:11,350 --> 00:02:09,599
but

50
00:02:13,350 --> 00:02:11,360
between now and then you know what's

51
00:02:14,949 --> 00:02:13,360
important is for me to pace myself to

52
00:02:17,350 --> 00:02:14,959
get enough rest

53
00:02:18,710 --> 00:02:17,360
to get enough exercise and

54
00:02:23,990 --> 00:02:18,720
you know because i'm in this for the

55
00:02:29,910 --> 00:02:25,910
what are you missing most at this point

56
00:02:33,750 --> 00:02:31,830
yeah you know you always miss uh i think

57
00:02:36,150 --> 00:02:33,760
what everyone misses the most is the

58
00:02:38,150 --> 00:02:36,160
humor human interaction you you have on

59
00:02:40,309 --> 00:02:38,160
earth with uh you know your family

60
00:02:42,309 --> 00:02:40,319
people you love your friends

61
00:02:44,070 --> 00:02:42,319
um

62
00:02:46,229 --> 00:02:44,080
you know even though we all get along

63
00:02:47,670 --> 00:02:46,239
great and we like each other

64
00:02:49,030 --> 00:02:47,680
there's not a whole lot of variety of

65
00:02:51,910 --> 00:02:49,040
people up here

66
00:02:52,790 --> 00:02:51,920
it's same people all day every day and

67
00:02:54,229 --> 00:02:52,800
uh

68
00:02:56,150 --> 00:02:54,239
so you miss

69
00:02:58,070 --> 00:02:56,160
the variety of that on earth you also

70
00:02:59,589 --> 00:02:58,080
miss uh the weather

71
00:03:01,910 --> 00:02:59,599
uh you know i know you've been having

72
00:03:03,430 --> 00:03:01,920
some bad weather in houston and uh you

73
00:03:06,229 --> 00:03:03,440
know i really feel for you guys down

74
00:03:09,270 --> 00:03:06,239
there uh it's really unfortunate the the

75
00:03:11,430 --> 00:03:09,280
tragedy and the the loss of life and uh

76
00:03:14,309 --> 00:03:11,440
you know property and

77
00:03:15,830 --> 00:03:14,319
that's that's occurred but uh

78
00:03:17,509 --> 00:03:15,840
when you're in this environment and it's

79
00:03:19,110 --> 00:03:17,519
a closed environment and there's no

80
00:03:21,190 --> 00:03:19,120
breeze there's no

81
00:03:22,949 --> 00:03:21,200
you know smell of nature there's no

82
00:03:25,350 --> 00:03:22,959
going outside

83
00:03:27,830 --> 00:03:25,360
walking around

84
00:03:29,750 --> 00:03:27,840
experiencing the rain although i know a

85
00:03:31,430 --> 00:03:29,760
lot of people in houston would like to

86
00:03:38,710 --> 00:03:31,440
not experience it rain for a while that

87
00:03:45,030 --> 00:03:41,190
what's it like i know you've sent a lot

88
00:03:47,350 --> 00:03:45,040
of amazing pictures from iss in your

89
00:03:49,190 --> 00:03:47,360
two months or so up there so far

90
00:03:50,949 --> 00:03:49,200
what's it like to see all of the flood

91
00:03:52,470 --> 00:03:50,959
waters from your perspective at this

92
00:03:58,070 --> 00:03:52,480
point when you look back upon the

93
00:04:01,270 --> 00:03:59,910
well you know we don't fly over the same

94
00:04:05,030 --> 00:04:01,280
spot of the gran

95
00:04:06,550 --> 00:04:05,040
spot over the ground um very often

96
00:04:08,789 --> 00:04:06,560
where

97
00:04:10,470 --> 00:04:08,799
the timing is right the lighting's right

98
00:04:13,670 --> 00:04:10,480
the weather is right

99
00:04:15,270 --> 00:04:13,680
and uh you know you're awake

100
00:04:17,270 --> 00:04:15,280
like for instance right now we're at

101
00:04:19,430 --> 00:04:17,280
what's called a high beta angle so we're

102
00:04:21,990 --> 00:04:19,440
kind of riding the you know the our

103
00:04:23,430 --> 00:04:22,000
orbit kind of parallels twilight for a

104
00:04:25,670 --> 00:04:23,440
lot of the time

105
00:04:27,670 --> 00:04:25,680
so it's kind of hard to see the ground

106
00:04:28,629 --> 00:04:27,680
plus in the case of houston with all the

107
00:04:32,390 --> 00:04:28,639
rain

108
00:04:34,070 --> 00:04:32,400
so

109
00:04:35,510 --> 00:04:34,080
you know we don't have a good view of

110
00:04:37,350 --> 00:04:35,520
the ground so

111
00:04:39,909 --> 00:04:37,360
you know i haven't had much opportunity

112
00:04:42,150 --> 00:04:39,919
to get get my eyeballs with a big lens

113
00:04:42,950 --> 00:04:42,160
or binoculars on houston a little bit

114
00:04:44,710 --> 00:04:42,960
but

115
00:04:47,909 --> 00:04:44,720
it's not like we can look at the window

116
00:04:53,350 --> 00:04:47,919
uh often and see the the kind of the

117
00:04:58,150 --> 00:04:55,749
scott talk a little bit about the the

118
00:04:59,590 --> 00:04:58,160
issues with cargo resupply with progress

119
00:05:01,909 --> 00:04:59,600
is failure

120
00:05:04,790 --> 00:05:01,919
how critical is it that

121
00:05:09,590 --> 00:05:04,800
food fuel supplies all get to you and

122
00:05:15,110 --> 00:05:12,710
well you know the space station has a

123
00:05:17,350 --> 00:05:15,120
lot of redundancy and and one area of

124
00:05:19,350 --> 00:05:17,360
redundancy is redundant vehicles to

125
00:05:20,629 --> 00:05:19,360
deliver cargo

126
00:05:22,150 --> 00:05:20,639
um

127
00:05:24,150 --> 00:05:22,160
you know progress is the only vehicle

128
00:05:27,029 --> 00:05:24,160
that delivers fuel but we have plenty on

129
00:05:28,550 --> 00:05:27,039
board to last us until the next one gets

130
00:05:29,430 --> 00:05:28,560
up here

131
00:05:31,430 --> 00:05:29,440
and

132
00:05:34,469 --> 00:05:31,440
like i said you know we have a redundant

133
00:05:36,870 --> 00:05:34,479
spacex vehicle hopefully orbital will be

134
00:05:39,189 --> 00:05:36,880
flying again soon htv

135
00:05:41,510 --> 00:05:39,199
we have one of those in august so we

136
00:05:43,510 --> 00:05:41,520
have uh you know a couple of spacex

137
00:05:44,629 --> 00:05:43,520
vehicles coming up in the near future

138
00:05:47,110 --> 00:05:44,639
htv

139
00:05:49,350 --> 00:05:47,120
and uh they'll definitely tide us over

140
00:05:54,550 --> 00:05:49,360
until uh progress gets flying again

141
00:05:58,070 --> 00:05:56,469
of all the research you've done so far

142
00:05:59,749 --> 00:05:58,080
scott what

143
00:06:05,029 --> 00:05:59,759
for you personally has been the most

144
00:06:09,430 --> 00:06:07,430
you know uh we do a lot of

145
00:06:10,950 --> 00:06:09,440
the human research is pretty interesting

146
00:06:13,510 --> 00:06:10,960
a lot of uh

147
00:06:16,469 --> 00:06:13,520
scans ultrasounds i was doing yesterday

148
00:06:19,029 --> 00:06:16,479
as part of this fluid shifts experiment

149
00:06:22,950 --> 00:06:19,039
um next week i'm going to do

150
00:06:26,230 --> 00:06:22,960
those uh those scans ultrasound scans

151
00:06:27,350 --> 00:06:26,240
while in this chibus which is a russian

152
00:06:29,749 --> 00:06:27,360
uh

153
00:06:32,309 --> 00:06:29,759
piece of hardware that the russians use

154
00:06:35,510 --> 00:06:32,319
to to you know mitigate the effects of

155
00:06:37,110 --> 00:06:35,520
weightlessness and the the fluid shifts

156
00:06:39,189 --> 00:06:37,120
and they use this prior to coming home

157
00:06:41,110 --> 00:06:39,199
so it pulls a vacuum on the lower part

158
00:06:43,430 --> 00:06:41,120
of your body and we're gonna i'm gonna

159
00:06:45,990 --> 00:06:43,440
be the first american

160
00:06:47,749 --> 00:06:46,000
to use that device since the mere days

161
00:06:48,950 --> 00:06:47,759
and we're gonna look at how with the

162
00:06:52,070 --> 00:06:48,960
ultrasound

163
00:06:54,230 --> 00:06:52,080
and some other imaging techniques how um

164
00:06:57,029 --> 00:06:54,240
you know the changes in pressure

165
00:06:59,589 --> 00:06:57,039
uh to our brain up here

166
00:07:01,830 --> 00:06:59,599
uh you know affects the vessels and and

167
00:07:03,749 --> 00:07:01,840
what that effect may have on you know

168
00:07:06,469 --> 00:07:03,759
visu the issues with our vision for

169
00:07:08,629 --> 00:07:06,479
instance um so for me that's been pretty

170
00:07:10,469 --> 00:07:08,639
interesting a lot of the the experiments

171
00:07:12,390 --> 00:07:10,479
we do especially the medical stuff are

172
00:07:13,909 --> 00:07:12,400
human samples so we don't really see the

173
00:07:17,510 --> 00:07:13,919
uh you know the immediate effects of

174
00:07:18,469 --> 00:07:17,520
those but uh you know that and all the

175
00:07:23,830 --> 00:07:18,479
all the other stuff is really

176
00:07:28,710 --> 00:07:25,749
scott i know your your friend tom cook

177
00:07:30,469 --> 00:07:28,720
down here says hello told me to send you

178
00:07:31,670 --> 00:07:30,479
his regard saw that you tweeted a

179
00:07:34,070 --> 00:07:31,680
picture of

180
00:07:40,230 --> 00:07:34,080
watching eyewitness news this morning

181
00:07:44,790 --> 00:07:41,670
yeah we you know we have a good

182
00:07:47,749 --> 00:07:44,800
capability to get recorded and sometimes

183
00:07:49,510 --> 00:07:47,759
live video up here uh so generally when

184
00:07:50,469 --> 00:07:49,520
we're having our meals we can watch the

185
00:07:54,150 --> 00:07:50,479
news

186
00:07:55,830 --> 00:07:54,160
morning that was actually uh several

187
00:07:57,909 --> 00:07:55,840
weeks ago but it's uh

188
00:08:03,589 --> 00:07:57,919
great to watch you guys and some other

189
00:08:06,230 --> 00:08:04,550
all right

190
00:08:09,990 --> 00:08:06,240
best to you and we'll talk to you very

191
00:08:13,510 --> 00:08:11,830
yeah my pleasure kevin good talking and

192
00:08:17,189 --> 00:08:13,520
uh hope to see you back on earth here

193
00:08:19,589 --> 00:08:17,199
and uh within the next year

194
00:08:22,309 --> 00:08:19,599
station this is houston acr that

195
00:08:24,629 --> 00:08:22,319
concludes the ktr cape tv portion of the

196
00:08:47,670 --> 00:08:24,639
event please stand by for a voice check

197
00:08:55,350 --> 00:08:50,310
hi there station this is pri science

198
00:08:59,910 --> 00:08:57,350
i have you loud and clear welcome aboard

199
00:09:10,470 --> 00:08:59,920
the international space station

200
00:09:15,829 --> 00:09:12,230
uh scott your your longest mission

201
00:09:17,269 --> 00:09:15,839
before this was 159 days um how do you

202
00:09:19,350 --> 00:09:17,279
compare that mission do you have a

203
00:09:24,630 --> 00:09:19,360
different mindset that you do for a

204
00:09:28,150 --> 00:09:26,150
you know absolutely it's the last time i

205
00:09:29,990 --> 00:09:28,160
was here a little bit more than uh

206
00:09:33,430 --> 00:09:30,000
five months and uh you know like i was

207
00:09:35,829 --> 00:09:33,440
saying earlier when you uh

208
00:09:37,990 --> 00:09:35,839
when it's that duration at least in my

209
00:09:40,150 --> 00:09:38,000
case you can kind of see the the end of

210
00:09:43,350 --> 00:09:40,160
it from from the beginning

211
00:09:45,110 --> 00:09:43,360
uh i launched in october got uh

212
00:09:46,550 --> 00:09:45,120
i got home in march

213
00:09:49,670 --> 00:09:46,560
and you just look you know you look at

214
00:09:50,870 --> 00:09:49,680
it on almost as a month-to-month basis

215
00:09:53,590 --> 00:09:50,880
you know get through november

216
00:09:55,750 --> 00:09:53,600
thanksgiving december christmas and then

217
00:09:57,590 --> 00:09:55,760
the new year's and pretty soon it's

218
00:10:00,550 --> 00:09:57,600
almost time to come home

219
00:10:03,030 --> 00:10:00,560
this time it's much different

220
00:10:03,829 --> 00:10:03,040
you know i know i'll come home someday

221
00:10:05,509 --> 00:10:03,839
but

222
00:10:07,269 --> 00:10:05,519
from my perspective

223
00:10:09,030 --> 00:10:07,279
i live and work here now i'm going to be

224
00:10:10,870 --> 00:10:09,040
here for a long time and

225
00:10:12,710 --> 00:10:10,880
as such i just kind of have to pace

226
00:10:15,030 --> 00:10:12,720
myself

227
00:10:17,350 --> 00:10:15,040
we talked to don pettit a little while

228
00:10:19,670 --> 00:10:17,360
back about the zero gravity cups and

229
00:10:24,630 --> 00:10:19,680
espresso maker have you been clinking

230
00:10:30,630 --> 00:10:28,550
you know we uh we used don's cup um

231
00:10:33,590 --> 00:10:30,640
that he designed when we used the

232
00:10:34,870 --> 00:10:33,600
espresso maker uh early on once we had

233
00:10:37,509 --> 00:10:34,880
it hooked up

234
00:10:40,069 --> 00:10:37,519
i was surprised at how well it actually

235
00:10:41,509 --> 00:10:40,079
worked i didn't think it would would uh

236
00:10:43,509 --> 00:10:41,519
you know make it seem like you were

237
00:10:45,190 --> 00:10:43,519
drinking out of a cup it's pretty a

238
00:10:47,269 --> 00:10:45,200
pretty clever design

239
00:10:49,350 --> 00:10:47,279
but we don't have a whole lot of uh of

240
00:10:51,350 --> 00:10:49,360
those capsules for the espresso machine

241
00:10:53,430 --> 00:10:51,360
so we haven't used it in a while and

242
00:10:56,310 --> 00:10:53,440
hopefully we will and

243
00:10:59,590 --> 00:10:56,320
hopefully and and i samantha's throwing

244
00:11:01,190 --> 00:10:59,600
the cup at me real quick to show you so

245
00:11:02,389 --> 00:11:01,200
here here's the cup

246
00:11:03,990 --> 00:11:02,399
and uh

247
00:11:05,509 --> 00:11:04,000
yeah like i said it's pretty incredible

248
00:11:07,910 --> 00:11:05,519
how when you go like this it actually

249
00:11:09,910 --> 00:11:07,920
seems to pour uh with gravity even

250
00:11:11,670 --> 00:11:09,920
though there's no gravity but haven't

251
00:11:13,110 --> 00:11:11,680
used it much but look forward to using

252
00:11:16,230 --> 00:11:13,120
it again

253
00:11:18,069 --> 00:11:16,240
we spoke to julie robinson from johnson

254
00:11:20,710 --> 00:11:18,079
and she mentioned something called

255
00:11:22,870 --> 00:11:20,720
suction pants that has to do with how

256
00:11:24,470 --> 00:11:22,880
microgravity affects your vision have

257
00:11:26,389 --> 00:11:24,480
you been able to try them out have you

258
00:11:31,829 --> 00:11:26,399
noticed that your vision is affected by

259
00:11:36,949 --> 00:11:34,470
well that's the first i've heard of that

260
00:11:39,350 --> 00:11:36,959
uh that term it it could be something

261
00:11:40,829 --> 00:11:39,360
that i had not have had training on or

262
00:11:43,030 --> 00:11:40,839
something that's going to come in the

263
00:11:43,990 --> 00:11:43,040
future um

264
00:11:45,750 --> 00:11:44,000
to

265
00:11:47,910 --> 00:11:45,760
i guess what she's probably talking

266
00:11:51,030 --> 00:11:47,920
about is mitigating the fluid shift that

267
00:11:52,870 --> 00:11:51,040
occurs you know gravity on earth pushes

268
00:11:55,110 --> 00:11:52,880
a lot of the fluid you know out of your

269
00:11:57,350 --> 00:11:55,120
head towards your feet and up here it's

270
00:11:59,750 --> 00:11:57,360
just all redistributed so you you

271
00:12:01,910 --> 00:11:59,760
generally have a higher pressure in your

272
00:12:03,269 --> 00:12:01,920
head and that's why some astronauts me

273
00:12:05,269 --> 00:12:03,279
included when they first get up here

274
00:12:08,230 --> 00:12:05,279
they kind of have a puffy head and that

275
00:12:10,710 --> 00:12:08,240
kind of continues as far as my vision

276
00:12:12,629 --> 00:12:10,720
you know it seems like my middle vision

277
00:12:14,310 --> 00:12:12,639
uh is and distance vision is a little

278
00:12:15,350 --> 00:12:14,320
bit better my reading vision's a little

279
00:12:16,550 --> 00:12:15,360
bit worse

280
00:12:18,790 --> 00:12:16,560
um

281
00:12:19,910 --> 00:12:18,800
you know it varies from time to time up

282
00:12:21,269 --> 00:12:19,920
here

283
00:12:24,150 --> 00:12:21,279
you know i did have some little bit of

284
00:12:25,990 --> 00:12:24,160
structural changes last time

285
00:12:27,269 --> 00:12:26,000
and i'm sure i'll have that this time

286
00:12:28,389 --> 00:12:27,279
and

287
00:12:30,710 --> 00:12:28,399
you know it's

288
00:12:32,710 --> 00:12:30,720
part of the price that some people pay

289
00:12:35,190 --> 00:12:32,720
for going up here and we're trying to

290
00:12:37,110 --> 00:12:35,200
understand it better and understand the

291
00:12:38,470 --> 00:12:37,120
risks and how to mitigate those risks

292
00:12:40,870 --> 00:12:38,480
and hopefully some of the experiments

293
00:12:43,190 --> 00:12:40,880
we're doing on board even next week will

294
00:12:45,750 --> 00:12:43,200
help us do that

295
00:12:47,910 --> 00:12:45,760
the russians had a cosmonaut up there

296
00:12:50,389 --> 00:12:47,920
for 14 months did you talk to him did he

297
00:12:54,389 --> 00:12:50,399
give you any hints or tips about what to

298
00:13:00,389 --> 00:12:56,949
i did not talk to him um i don't think

299
00:13:02,790 --> 00:13:00,399
i've ever met him but uh i did talk to

300
00:13:04,629 --> 00:13:02,800
vladimir titov who spent about a year in

301
00:13:07,750 --> 00:13:04,639
space on

302
00:13:09,590 --> 00:13:07,760
the mir space station and uh he gave me

303
00:13:11,670 --> 00:13:09,600
uh you know one bit of advice and it's

304
00:13:12,949 --> 00:13:11,680
just like it was basically just pace

305
00:13:15,670 --> 00:13:12,959
yourself you know you're gonna be there

306
00:13:18,069 --> 00:13:15,680
for a long time and just uh

307
00:13:20,470 --> 00:13:18,079
you know try to keep

308
00:13:22,389 --> 00:13:20,480
a good balance of work and rest and

309
00:13:24,550 --> 00:13:22,399
you'll do just fine

310
00:13:27,590 --> 00:13:24,560
we're speaking to your brother mark

311
00:13:29,910 --> 00:13:27,600
today also now which one of you

312
00:13:36,230 --> 00:13:29,920
has the better right stuff sibling right

313
00:13:36,240 --> 00:13:41,269
uh that would be me

314
00:13:45,430 --> 00:13:43,189
why am i not i'm sure

315
00:13:47,509 --> 00:13:45,440
but i'm sure

316
00:13:48,629 --> 00:13:47,519
now i'm sure he would say the same thing

317
00:13:50,069 --> 00:13:48,639
you know we're

318
00:13:51,910 --> 00:13:50,079
we are uh

319
00:13:54,230 --> 00:13:51,920
you know i'm just kidding around i have

320
00:13:55,750 --> 00:13:54,240
no idea you know we're we're

321
00:13:56,870 --> 00:13:55,760
similar in a lot of ways different than

322
00:13:58,389 --> 00:13:56,880
others we're

323
00:14:01,269 --> 00:13:58,399
you know naturally competitive people

324
00:14:03,910 --> 00:14:01,279
but not not competitive with uh you know

325
00:14:05,910 --> 00:14:03,920
between each other uh you know our

326
00:14:08,389 --> 00:14:05,920
experiences in space are

327
00:14:10,230 --> 00:14:08,399
have been a little bit different um but

328
00:14:12,389 --> 00:14:10,240
we both recognize that just having the

329
00:14:14,710 --> 00:14:12,399
ability to fly in space once

330
00:14:15,910 --> 00:14:14,720
is a real privilege and

331
00:14:17,350 --> 00:14:15,920
you know it's just really been an

332
00:14:18,310 --> 00:14:17,360
incredible thing that we could share

333
00:14:20,550 --> 00:14:18,320
together

334
00:14:22,790 --> 00:14:20,560
this great experience and you know both

335
00:14:25,990 --> 00:14:22,800
of us having flown four times is really

336
00:14:27,670 --> 00:14:26,000
uh you know hard to hard to believe

337
00:14:29,750 --> 00:14:27,680
i i know he's on the ground here

338
00:14:32,389 --> 00:14:29,760
comparing what happens to him during

339
00:14:34,949 --> 00:14:32,399
your time up there in space have have

340
00:14:39,430 --> 00:14:34,959
you two noticed any differences already

341
00:14:44,550 --> 00:14:42,069
well most of that comparative research

342
00:14:46,550 --> 00:14:44,560
is is uh you know with

343
00:14:47,990 --> 00:14:46,560
samples of blood and urine and other

344
00:14:50,470 --> 00:14:48,000
things and uh

345
00:14:54,550 --> 00:14:50,480
you know cognitive ability uh some

346
00:14:57,670 --> 00:14:54,560
cognitive experiments experiments using

347
00:14:59,990 --> 00:14:57,680
mris and you know structural changes

348
00:15:00,870 --> 00:15:00,000
within our our bodies and the chemistry

349
00:15:02,949 --> 00:15:00,880
of our

350
00:15:04,629 --> 00:15:02,959
our bodies our genetics things like that

351
00:15:05,590 --> 00:15:04,639
so there's there's stuff that you don't

352
00:15:09,189 --> 00:15:05,600
see

353
00:15:13,030 --> 00:15:09,199
um that uh you know the researchers at

354
00:15:14,710 --> 00:15:13,040
some point will uh publish papers on you

355
00:15:17,509 --> 00:15:14,720
know for instance how

356
00:15:19,750 --> 00:15:17,519
you know my dna looked one way before

357
00:15:22,150 --> 00:15:19,760
flight and and how he's compared before

358
00:15:24,629 --> 00:15:22,160
flight and then maybe how mine changed

359
00:15:27,590 --> 00:15:24,639
over time while i was here where his you

360
00:15:29,749 --> 00:15:27,600
know in a certain area stayed the same

361
00:15:31,990 --> 00:15:29,759
uh but that's not stuff you can

362
00:15:33,350 --> 00:15:32,000
that we can see at this point but uh you

363
00:15:35,030 --> 00:15:33,360
know stuff that's very important

364
00:15:37,350 --> 00:15:35,040
nonetheless

365
00:15:39,430 --> 00:15:37,360
we asked our listeners what questions

366
00:15:42,150 --> 00:15:39,440
they had for you and we have a couple of

367
00:15:44,629 --> 00:15:42,160
them from twitter i'm gonna see if i can

368
00:15:47,189 --> 00:15:44,639
share them with you david she wanted to

369
00:15:50,310 --> 00:15:47,199
know if the likelihood of infection is

370
00:15:52,150 --> 00:15:50,320
higher on earth or on iss

371
00:15:53,990 --> 00:15:52,160
and is there a fat an effect on your

372
00:15:58,550 --> 00:15:54,000
microbiome and would you are you

373
00:16:03,350 --> 00:16:00,310
yeah so one of the the studies we're

374
00:16:05,590 --> 00:16:03,360
doing uh with my brother is a microbiome

375
00:16:07,269 --> 00:16:05,600
study how the mic your microbiome

376
00:16:09,509 --> 00:16:07,279
changes in the microbiome for people

377
00:16:11,670 --> 00:16:09,519
that might not be familiar with it is

378
00:16:14,150 --> 00:16:11,680
you know all this bacteria that resides

379
00:16:15,990 --> 00:16:14,160
within your digestive system

380
00:16:18,150 --> 00:16:16,000
and apparently from what i understand

381
00:16:21,189 --> 00:16:18,160
there's more of those cells

382
00:16:23,509 --> 00:16:21,199
that aren't you than there are of your

383
00:16:25,829 --> 00:16:23,519
own human cells so

384
00:16:26,949 --> 00:16:25,839
it's uh you know it's critical to our

385
00:16:30,550 --> 00:16:26,959
our

386
00:16:32,949 --> 00:16:30,560
it does change

387
00:16:36,069 --> 00:16:32,959
when uh when we're in space

388
00:16:39,189 --> 00:16:36,079
um and we're comparing that you know my

389
00:16:41,189 --> 00:16:39,199
the changes in in my microbiome with my

390
00:16:43,509 --> 00:16:41,199
brothers over over the period of time

391
00:16:45,110 --> 00:16:43,519
that we're here um and

392
00:16:47,509 --> 00:16:45,120
as getting back to the first part of

393
00:16:50,470 --> 00:16:47,519
your question about infections

394
00:16:52,069 --> 00:16:50,480
our immune system generally is depressed

395
00:16:53,749 --> 00:16:52,079
up here for

396
00:16:55,990 --> 00:16:53,759
you know i'm not sure why maybe someone

397
00:16:57,350 --> 00:16:56,000
knows exactly why but we actually are

398
00:16:58,069 --> 00:16:57,360
studying that

399
00:17:01,910 --> 00:16:58,079
so

400
00:17:04,549 --> 00:17:01,920
would be uh

401
00:17:06,309 --> 00:17:04,559
you know a little bit more prone to

402
00:17:08,630 --> 00:17:06,319
certain types of infections things that

403
00:17:10,630 --> 00:17:08,640
we have on board here that can

404
00:17:13,429 --> 00:17:10,640
infect you but for instance you know

405
00:17:15,189 --> 00:17:13,439
there's no uh cold virus up here the flu

406
00:17:18,549 --> 00:17:15,199
virus things like that

407
00:17:20,150 --> 00:17:18,559
um certain types of bacteria we

408
00:17:21,750 --> 00:17:20,160
don't have them on the space station

409
00:17:24,150 --> 00:17:21,760
therefore you know people generally

410
00:17:28,150 --> 00:17:24,160
don't get get sick like you might on

411
00:17:30,310 --> 00:17:28,160
earth at least not uh not very often

412
00:17:33,190 --> 00:17:30,320
all right scott thank you very much for

413
00:17:37,190 --> 00:17:33,200
taking time to be with us today and good

414
00:17:46,310 --> 00:17:39,669
yeah my pleasure uh thank you and it was

415
00:17:51,750 --> 00:17:48,230
this is houston acr

416
00:17:54,390 --> 00:17:51,760
thank you that concludes our event

417
00:17:56,390 --> 00:17:54,400
and thank you ktrk tv and prize science
