00:02:49,840 we don't get any free time so i have to 53 00:02:53,589 --> 00:02:51,680 steal it from the boss 54 00:02:54,790 --> 00:02:53,599 pretty much but uh the most i think 55 00:02:56,070 --> 00:02:54,800 everybody does that when they get a 56 00:02:57,910 --> 00:02:56,080 moment off they kind of look out the 57 00:02:59,830 --> 00:02:57,920 window and just see the whole world go 58 00:03:07,750 --> 00:02:59,840 by it's like a geography lesson it's 59 00:03:12,790 --> 00:03:09,750 hi my name is yvette i am a fourth 60 00:03:14,869 --> 00:03:12,800 grader in harlingen texas i am bilingual 61 00:03:16,869 --> 00:03:14,879 and i was wondering how many languages 62 00:03:23,509 --> 00:03:16,879 you need to speak to work on the 63 00:03:27,110 --> 00:03:24,390 i think 64 00:03:29,750 --> 00:03:27,120 good question 65 00:03:31,670 --> 00:03:29,760 uh well the the official main language 66 00:03:33,430 --> 00:03:31,680 on the space station one that we all 67 00:03:34,550 --> 00:03:33,440 understand is english 68 00:03:36,229 --> 00:03:34,560 however 69 00:03:38,789 --> 00:03:36,239 it's very essential that you learn 70 00:03:41,910 --> 00:03:38,799 russian as well since uh we tend to 71 00:03:43,190 --> 00:03:41,920 operate uh in the soyuz or we do operate 72 00:03:46,789 --> 00:03:43,200 in the soyuz 73 00:03:48,869 --> 00:03:46,799 spacecraft solely in russian um but we 74 00:03:50,630 --> 00:03:48,879 have a lot of talented very bright 75 00:03:54,309 --> 00:03:50,640 people on board and some of them know 76 00:03:58,470 --> 00:03:54,319 several languages such as japanese 77 00:04:00,470 --> 00:03:58,480 got suici on board and uh french german 78 00:04:02,070 --> 00:04:00,480 tj knows german so 79 00:04:04,309 --> 00:04:02,080 it's a when you have an international 80 00:04:11,670 --> 00:04:04,319 space station it's almost endless uh the 81 00:04:16,229 --> 00:04:13,750 my name is paige and i go to later 82 00:04:18,870 --> 00:04:16,239 middle school and lived in kentucky my 83 00:04:21,349 --> 00:04:18,880 question is what does it feel like after 84 00:04:26,870 --> 00:04:21,359 being on the space station when you come 85 00:04:32,150 --> 00:04:28,950 i can answer that 86 00:04:36,710 --> 00:04:34,150 well uh when you come back to earth 87 00:04:39,670 --> 00:04:36,720 things feel really really heavy 88 00:04:41,189 --> 00:04:39,680 um i remember taking off my helmet and 89 00:04:43,189 --> 00:04:41,199 feeling like i was holding a pickup 90 00:04:44,629 --> 00:04:43,199 truck in my hand it felt so incredibly i 91 00:04:46,390 --> 00:04:44,639 was like oh my goodness how am i ever 92 00:04:49,030 --> 00:04:46,400 going to brush my teeth my toothbrush is 93 00:04:51,270 --> 00:04:49,040 going to feel like a ton of bricks but 94 00:04:53,430 --> 00:04:51,280 um turns out that you get really used to 95 00:04:54,710 --> 00:04:53,440 gravity again pretty quickly within like 96 00:04:55,990 --> 00:04:54,720 an hour or so 97 00:04:58,070 --> 00:04:56,000 and 98 00:05:00,469 --> 00:04:58,080 you uh after it takes a little while for 99 00:05:01,990 --> 00:05:00,479 you to get all your senses back uh and 100 00:05:04,390 --> 00:05:02,000 they won't let you drive a car usually 101 00:05:05,830 --> 00:05:04,400 for about a month but uh other than that 102 00:05:13,909 --> 00:05:05,840 uh after about a month you're pretty 103 00:05:17,990 --> 00:05:16,070 my name is antonio and i go to 104 00:05:20,469 --> 00:05:18,000 elementary learning center in cudahy 105 00:05:30,790 --> 00:05:20,479 california and my question is is there 106 00:05:33,909 --> 00:05:31,749 hey 107 00:05:36,310 --> 00:05:33,919 well we're going very very fast up here 108 00:05:38,230 --> 00:05:36,320 five miles per second but we're out of 109 00:05:39,830 --> 00:05:38,240 the atmosphere but there's a little bit 110 00:05:41,830 --> 00:05:39,840 of atmosphere left there so there are a 111 00:05:43,990 --> 00:05:41,840 few atoms i guess hitting the front of 112 00:05:46,230 --> 00:05:44,000 station at five miles per second so 113 00:05:48,469 --> 00:05:46,240 that's a very weak wind but it's enough 114 00:05:50,150 --> 00:05:48,479 to slow the space station down and make 115 00:05:52,390 --> 00:05:50,160 it slowly fall back to earth so every so 116 00:05:54,230 --> 00:05:52,400 often we have to boost it back up again 117 00:06:02,070 --> 00:05:54,240 using a rocket motor on the back of the 118 00:06:06,629 --> 00:06:04,629 my name is aaron smith and i go to 119 00:06:09,029 --> 00:06:06,639 orleans elementary school 120 00:06:11,350 --> 00:06:09,039 in orleans vermont my question is what 121 00:06:18,629 --> 00:06:11,360 is the temperature at the international 122 00:06:22,629 --> 00:06:20,710 inside here it's uh 123 00:06:24,230 --> 00:06:22,639 just like it is at school for you it's 124 00:06:26,870 --> 00:06:24,240 room temperature very comfortable we're 125 00:06:29,670 --> 00:06:26,880 just working out here in shirt sleeves 126 00:06:31,990 --> 00:06:29,680 but when we go outside on our spacewalks 127 00:06:34,950 --> 00:06:32,000 the temperatures can vary plus or minus 128 00:06:44,150 --> 00:06:34,960 200 degrees depending on whether the 129 00:06:48,390 --> 00:06:46,230 hi my name is jackson i am a sixth 130 00:06:50,950 --> 00:06:48,400 grader at hobgood elementary in 131 00:06:52,469 --> 00:06:50,960 murfreesboro tennessee my question is 132 00:06:54,230 --> 00:06:52,479 what is one of the worst and best 133 00:06:59,909 --> 00:06:54,240 effects of being in a microgravity 134 00:07:05,670 --> 00:07:01,029 for 135 00:07:07,029 --> 00:07:05,680 it's very nice to be able to float 136 00:07:09,430 --> 00:07:07,039 that's probably the best effect you get 137 00:07:12,469 --> 00:07:09,440 to hang around and float and you can 138 00:07:13,749 --> 00:07:12,479 become an expert gymnast in seconds you 139 00:07:15,430 --> 00:07:13,759 can do all sorts of things you can't do 140 00:07:17,350 --> 00:07:15,440 on the ground 141 00:07:19,270 --> 00:07:17,360 one of the long-term problems with being 142 00:07:21,990 --> 00:07:19,280 in this environment however is 143 00:07:23,430 --> 00:07:22,000 bone loss muscle deconditioning and 144 00:07:25,350 --> 00:07:23,440 over time we're starting to learn how to 145 00:07:27,110 --> 00:07:25,360 deal with that on board tracy here works 146 00:07:28,629 --> 00:07:27,120 out several hours a day trying to stay 147 00:07:31,029 --> 00:07:28,639 strong so when she gets home in six 148 00:07:37,909 --> 00:07:31,039 months she can 149 00:07:42,150 --> 00:07:40,230 my name is sammy and i am a senior at 150 00:07:44,230 --> 00:07:42,160 wendover high school my question is how 151 00:07:55,510 --> 00:07:44,240 do you feel about flying on the last 152 00:08:00,070 --> 00:07:58,309 well we're not exactly sure that this is 153 00:08:02,469 --> 00:08:00,080 in fact the last space shuttle flight of 154 00:08:04,469 --> 00:08:02,479 atlantis uh if it is though we all 155 00:08:06,469 --> 00:08:04,479 consider it just as important as any of 156 00:08:09,029 --> 00:08:06,479 the other flights this was the 32nd 157 00:08:10,629 --> 00:08:09,039 flight 32nd time that atlantis has 158 00:08:12,309 --> 00:08:10,639 launched into space 159 00:08:13,909 --> 00:08:12,319 and flown around the earth many many 160 00:08:16,390 --> 00:08:13,919 times so we're just another crew to be 161 00:08:18,869 --> 00:08:16,400 lucky enough to be part of that program 162 00:08:25,990 --> 00:08:18,879 and if it's the last flight 163 00:08:32,149 --> 00:08:28,869 my name is charles and i go to john b 164 00:08:34,230 --> 00:08:32,159 carey in richmond virginia my question 165 00:08:40,469 --> 00:08:34,240 is did you like training to be an 166 00:08:43,670 --> 00:08:41,909 yeah well that's a great question 167 00:08:45,190 --> 00:08:43,680 actually training to be an astronaut is 168 00:08:48,230 --> 00:08:45,200 a lot of fun 169 00:08:49,829 --> 00:08:48,240 uh we get to fly airplanes around work 170 00:08:52,790 --> 00:08:49,839 in the simulator 171 00:08:54,470 --> 00:08:52,800 and go to class all the things that you 172 00:08:57,509 --> 00:08:54,480 would learn in school 173 00:08:59,190 --> 00:08:57,519 we've been training uh the sts-132 crew 174 00:09:01,430 --> 00:08:59,200 has been training about eight months so 175 00:09:02,870 --> 00:09:01,440 just about a a school year getting ready 176 00:09:09,509 --> 00:09:02,880 for this mission but 177 00:09:14,389 --> 00:09:12,070 my name is serena anderson and i go to 178 00:09:18,070 --> 00:09:14,399 cumberland middle school in cumberland 179 00:09:19,430 --> 00:09:18,080 wisconsin my question is when you go up 180 00:09:21,190 --> 00:09:19,440 into space 181 00:09:28,870 --> 00:09:21,200 like how much pressure is it and how 182 00:09:33,910 --> 00:09:31,750 right so um here on the space station 183 00:09:35,870 --> 00:09:33,920 the uh the atmospheric pressure in here 184 00:09:38,630 --> 00:09:35,880 is just like sea level 185 00:09:40,710 --> 00:09:38,640 14.7 psi 186 00:09:41,590 --> 00:09:40,720 as far as like during launch we feel a 187 00:09:43,829 --> 00:09:41,600 lot of 188 00:09:46,949 --> 00:09:43,839 forces acceleration as we're going up in 189 00:09:49,190 --> 00:09:46,959 the space shuttle up to three times our 190 00:09:51,030 --> 00:09:49,200 normal body weight so it feels like 191 00:09:53,430 --> 00:09:51,040 there's uh three of your friends 192 00:09:55,269 --> 00:09:53,440 standing on your chest um as you're 193 00:09:56,870 --> 00:09:55,279 launching into space and 194 00:09:58,550 --> 00:09:56,880 sometimes it's a little bit of work just 195 00:10:01,590 --> 00:09:58,560 to raise your uh 196 00:10:03,990 --> 00:10:01,600 chest up to get some air into your lungs 197 00:10:06,470 --> 00:10:04,000 but uh after a couple days here on 198 00:10:14,069 --> 00:10:06,480 on station you really adapt to all this 199 00:10:17,990 --> 00:10:16,230 hi my name is megan and i'm from warren 200 00:10:19,910 --> 00:10:18,000 g hardy middle school in des moines iowa 201 00:10:21,670 --> 00:10:19,920 and my question is is how long does it 202 00:10:27,110 --> 00:10:21,680 take for 203 00:10:30,790 --> 00:10:29,509 now this is a tricky question 204 00:10:32,630 --> 00:10:30,800 how long does it take for water for 205 00:10:34,630 --> 00:10:32,640 evaporating space if you put some water 206 00:10:36,230 --> 00:10:34,640 out of space if you're on the night side 207 00:10:39,829 --> 00:10:36,240 of the earth it'll just freeze solid in 208 00:10:42,310 --> 00:10:39,839 or like a rock hard iceberg immediately 209 00:10:45,190 --> 00:10:42,320 if you're on the 210 00:10:46,630 --> 00:10:45,200 on the sun side it'll flash and boil 211 00:10:48,870 --> 00:10:46,640 almost immediately and you'll just get 212 00:10:50,150 --> 00:10:48,880 water vapor and sometimes there's some 213 00:10:52,389 --> 00:10:50,160 places where the water doesn't know 214 00:10:54,389 --> 00:10:52,399 whether to freeze or boil and it kind of 215 00:11:01,670 --> 00:10:54,399 does both at the same time 216 00:11:05,110 --> 00:11:03,269 my name is charles wallace and i go to 217 00:11:07,509 --> 00:11:05,120 cairo's middle school in congress 218 00:11:09,590 --> 00:11:07,519 georgia i would like to know 219 00:11:24,310 --> 00:11:09,600 are there any concerns about the closure 220 00:11:28,470 --> 00:11:25,750 well the end of the space shuttle 221 00:11:31,590 --> 00:11:28,480 program is essentially inevitable and 222 00:11:34,310 --> 00:11:31,600 that is because the space shuttle can't 223 00:11:36,389 --> 00:11:34,320 travel outside of low earth orbit and if 224 00:11:39,110 --> 00:11:36,399 we as humans want to 225 00:11:40,230 --> 00:11:39,120 explore deeper into the universe 226 00:11:41,750 --> 00:11:40,240 um 227 00:11:43,590 --> 00:11:41,760 it's starting with maybe the moon moving 228 00:11:45,350 --> 00:11:43,600 on to asteroids and mars 229 00:11:47,910 --> 00:11:45,360 the the space shuttle is not the machine 230 00:11:49,910 --> 00:11:47,920 that can do it so we simply don't have 231 00:11:51,829 --> 00:11:49,920 enough money to continue to operate the 232 00:11:53,990 --> 00:11:51,839 space shuttle and develop a whole new 233 00:11:55,110 --> 00:11:54,000 spacecraft that can go beyond low earth 234 00:11:57,269 --> 00:11:55,120 orbit 235 00:12:00,230 --> 00:11:57,279 so it's a it's a decision of 236 00:12:01,910 --> 00:12:00,240 national will you know if we want to 237 00:12:03,430 --> 00:12:01,920 explore the universe we've got to stop 238 00:12:04,949 --> 00:12:03,440 flying the space shuttle and it's a 239 00:12:10,550 --> 00:12:04,959 simple reality 240 00:12:14,389 --> 00:12:13,110 my name is william 241 00:12:16,389 --> 00:12:14,399 and 242 00:12:19,670 --> 00:12:16,399 in first grade 243 00:12:23,350 --> 00:12:19,680 in forest lake elementary 244 00:12:25,509 --> 00:12:23,360 in columbia south carolina my question 245 00:12:35,350 --> 00:12:25,519 is 246 00:12:38,550 --> 00:12:37,670 hey william uh thanks for asking that 247 00:12:41,030 --> 00:12:38,560 question 248 00:12:42,470 --> 00:12:41,040 um it's a good one uh the reason that 249 00:12:44,069 --> 00:12:42,480 there's not as much you don't feel as 250 00:12:46,629 --> 00:12:44,079 much gravity on the moon 251 00:12:48,310 --> 00:12:46,639 is because it's smaller than the earth 252 00:12:50,870 --> 00:12:48,320 the amount of gravity that a given 253 00:12:52,949 --> 00:12:50,880 planet uh or any anything for that 254 00:12:55,829 --> 00:12:52,959 matter poles on everything else 255 00:12:58,230 --> 00:12:55,839 ha is uh related to how big it is how 256 00:13:01,190 --> 00:12:58,240 much mass it has so the moon has a lot 257 00:13:03,350 --> 00:13:01,200 less mass than the earth so there's less 258 00:13:05,509 --> 00:13:03,360 gravity and if you go to jupiter which 259 00:13:08,310 --> 00:13:05,519 has got a lot more mass than the earth 260 00:13:10,790 --> 00:13:08,320 then you'd feel a lot of gravity and 261 00:13:17,030 --> 00:13:10,800 you'd feel really really heavy so that's 262 00:13:21,509 --> 00:13:19,030 hi my name is michelle i'm a junior 263 00:13:23,590 --> 00:13:21,519 wendover high my question is what is it 264 00:13:33,269 --> 00:13:23,600 like seeing the sunset or sun rise every 265 00:13:37,910 --> 00:13:34,790 because of the well i'm starting to 266 00:13:41,030 --> 00:13:39,189 no because you get to go around the 267 00:13:43,269 --> 00:13:41,040 earth every 90 minutes or so you 268 00:13:45,350 --> 00:13:43,279 naturally see a sunset in the sunrise 269 00:13:46,949 --> 00:13:45,360 every 90 minutes and it's really amazing 270 00:13:48,790 --> 00:13:46,959 because you get to watch 271 00:13:50,470 --> 00:13:48,800 you know the earth below you both at 272 00:13:51,590 --> 00:13:50,480 night and during the day in just an hour 273 00:13:53,430 --> 00:13:51,600 and a half 274 00:13:54,710 --> 00:13:53,440 which is really really exciting the 275 00:13:55,750 --> 00:13:54,720 problem becomes when you're trying to go 276 00:13:57,110 --> 00:13:55,760 to sleep 277 00:13:58,550 --> 00:13:57,120 for some people 278 00:14:00,550 --> 00:13:58,560 because you have to have to shut the 279 00:14:01,670 --> 00:14:00,560 windows and seal yourself off inside and 280 00:14:02,710 --> 00:14:01,680 turn out the lights because otherwise 281 00:14:04,629 --> 00:14:02,720 you'd have the light coming through the 282 00:14:08,310 --> 00:14:04,639 windows every 45 minutes and that might 283 00:14:12,870 --> 00:14:10,949 oh outside oh going outside is eva 284 00:14:14,470 --> 00:14:12,880 that's a lot more fun because you're not 285 00:14:17,110 --> 00:14:14,480 constrained by the windows and you have 286 00:14:18,069 --> 00:14:17,120 the opportunity to look down and see the 287 00:14:19,910 --> 00:14:18,079 earth 288 00:14:21,670 --> 00:14:19,920 pass below your feet 289 00:14:23,910 --> 00:14:21,680 in darkness and in light and it's 290 00:14:25,269 --> 00:14:23,920 amazing what you can see at night uh not 291 00:14:27,590 --> 00:14:25,279 on this mission on a previous mission i 292 00:14:29,269 --> 00:14:27,600 saw a meteorite pass below me into the 293 00:14:32,629 --> 00:14:29,279 atmosphere and glow and that was pretty 294 00:14:34,550 --> 00:14:32,639 amazing lightning storms the aurora we 295 00:14:36,550 --> 00:14:34,560 saw the other day all sorts of amazing 296 00:14:38,230 --> 00:14:36,560 things you get to see outside at night 297 00:14:42,870 --> 00:14:38,240 that you don't necessarily think of you 298 00:14:45,670 --> 00:14:44,310 let me just add something to that real 299 00:14:47,509 --> 00:14:45,680 quick the other interesting thing about 300 00:14:50,150 --> 00:14:47,519 sunrises and sunsets up here though is 301 00:14:51,590 --> 00:14:50,160 that they happen really fast so it's not 302 00:14:53,590 --> 00:14:51,600 like at home when you're sitting on the 303 00:14:55,990 --> 00:14:53,600 beach and just enjoying the sunset go 304 00:14:57,990 --> 00:14:56,000 down into the ocean very slowly here it 305 00:14:59,590 --> 00:14:58,000 just happens uh so fast because we're 306 00:15:00,710 --> 00:14:59,600 traveling around the world so fast so 307 00:15:01,670 --> 00:15:00,720 you're out there and you're looking at 308 00:15:04,150 --> 00:15:01,680 the sun 309 00:15:13,030 --> 00:15:04,160 and it's bright bright bright bright 310 00:15:17,030 --> 00:15:14,870 hi my name is helena i'm a fourth grader 311 00:15:19,829 --> 00:15:17,040 in holland in texas in comparison to 312 00:15:21,670 --> 00:15:19,839 plant life on earth do the plants grown 313 00:15:26,870 --> 00:15:21,680 on the international space station grow 314 00:15:29,829 --> 00:15:28,710 selena that's a really uh mature 315 00:15:31,509 --> 00:15:29,839 question and 316 00:15:34,069 --> 00:15:31,519 you're ahead of your time the space 317 00:15:36,230 --> 00:15:34,079 station uh science 318 00:15:39,430 --> 00:15:36,240 on board here really is looking at that 319 00:15:41,509 --> 00:15:39,440 very question itself we're looking at 320 00:15:43,509 --> 00:15:41,519 arabidopsis seeds and trying to 321 00:15:46,629 --> 00:15:43,519 understand because we see that the roots 322 00:15:48,470 --> 00:15:46,639 grow in a different way here on orbit 323 00:15:50,310 --> 00:15:48,480 with the lack of gravity than they do on 324 00:15:52,949 --> 00:15:50,320 earth and we're hoping that that will 325 00:15:55,590 --> 00:15:52,959 help us to understand plant growth on 326 00:15:56,710 --> 00:15:55,600 earth a little better so i can tell you 327 00:15:58,310 --> 00:15:56,720 that 328 00:15:59,829 --> 00:15:58,320 they do grow a little differently but 329 00:16:01,590 --> 00:15:59,839 how that's something that we're studying 330 00:16:03,670 --> 00:16:01,600 right now it's kind of interesting to 331 00:16:04,949 --> 00:16:03,680 see plants growing up here in the space 332 00:16:10,550 --> 00:16:04,959 station 333 00:16:14,389 --> 00:16:12,230 my name is jackie black and i go to 334 00:16:16,870 --> 00:16:14,399 arapahoe middle school in 335 00:16:19,110 --> 00:16:16,880 arapahoe wyoming my question is do you 336 00:16:27,910 --> 00:16:19,120 take any medication for the function of 337 00:16:33,749 --> 00:16:30,710 actually i'd have to say no we don't 338 00:16:36,629 --> 00:16:33,759 take any medications uh that i know of 339 00:16:39,590 --> 00:16:36,639 but we are trying to understand 340 00:16:41,990 --> 00:16:39,600 better how to preserve bone mass up here 341 00:16:42,949 --> 00:16:42,000 on orbit for long duration and so one of 342 00:16:44,150 --> 00:16:42,959 the 343 00:16:47,030 --> 00:16:44,160 ways that we 344 00:16:49,829 --> 00:16:47,040 counteract the effect of gravity or the 345 00:16:52,230 --> 00:16:49,839 lack of gravity here on orbit is to do 346 00:16:54,790 --> 00:16:52,240 exercise we find that the more exercise 347 00:16:57,509 --> 00:16:54,800 we do before we launch into space as 348 00:16:58,710 --> 00:16:57,519 well as while we're on orbit helps to 349 00:17:00,550 --> 00:16:58,720 maintain 350 00:17:02,790 --> 00:17:00,560 our bone mass which is extremely 351 00:17:04,710 --> 00:17:02,800 important and we're trying to study that 352 00:17:06,069 --> 00:17:04,720 right now to see how much we need to do 353 00:17:08,549 --> 00:17:06,079 and for 354 00:17:11,110 --> 00:17:08,559 how frequent we need to do that in order 355 00:17:13,350 --> 00:17:11,120 to maintain and possibly even grow 356 00:17:15,270 --> 00:17:13,360 stronger bones on orbit and that will 357 00:17:16,069 --> 00:17:15,280 also help us to understand our own bone 358 00:17:18,309 --> 00:17:16,079 growth 359 00:17:24,710 --> 00:17:18,319 back at home on earth great questions 360 00:17:33,110 --> 00:17:27,829 atlantis iss this is houston acr thank 361 00:17:36,549 --> 00:17:34,710 thank you atlanta station and nasa 362
