1 00:00:05,349 --> 00:00:03,669 hi welcome to mission control houston 2 00:00:06,869 --> 00:00:05,359 and thank you for joining us today we're 3 00:00:08,710 --> 00:00:06,879 inside the international space station 4 00:00:11,110 --> 00:00:08,720 flight control room where the orbit 2 5 00:00:12,150 --> 00:00:11,120 team is monitoring the systems and the 6 00:00:14,070 --> 00:00:12,160 cruise activities aboard the 7 00:00:16,230 --> 00:00:14,080 international space station we're here 8 00:00:18,070 --> 00:00:16,240 today to talk with uh sixth to eighth 9 00:00:20,230 --> 00:00:18,080 grade students that are out at 10 00:00:22,710 --> 00:00:20,240 huntsville alabama at 11 00:00:24,390 --> 00:00:22,720 space camp and here with us today is a 12 00:00:26,790 --> 00:00:24,400 special guest she knows a little about 13 00:00:29,589 --> 00:00:26,800 space camp liz warren who is also the 14 00:00:30,950 --> 00:00:29,599 space station uh science communication 15 00:00:32,549 --> 00:00:30,960 coordinator 16 00:00:33,990 --> 00:00:32,559 welcome liz and thank you for coming 17 00:00:35,750 --> 00:00:34,000 thank you very much for having me i'm 18 00:00:38,229 --> 00:00:35,760 very excited to speak with you thank you 19 00:00:40,069 --> 00:00:38,239 and what is also very very very special 20 00:00:41,670 --> 00:00:40,079 about liz being here is 21 00:00:42,790 --> 00:00:41,680 well you've been here at nasa for eight 22 00:00:45,590 --> 00:00:42,800 years now 23 00:00:47,910 --> 00:00:45,600 and um she's a space camp graduate she 24 00:00:50,869 --> 00:00:47,920 went level one and level two 25 00:00:53,029 --> 00:00:50,879 and um it's also was recently inducted 26 00:00:55,510 --> 00:00:53,039 into the space camp hall of fame just 27 00:00:57,830 --> 00:00:55,520 this year yes i was congratulations it 28 00:00:59,830 --> 00:00:57,840 was a lot of fun it's a huge honor so 29 00:01:01,430 --> 00:00:59,840 many people have gone to space camp just 30 00:01:03,750 --> 00:01:01,440 like the students were speaking with 31 00:01:04,869 --> 00:01:03,760 today i believe while i was there in 32 00:01:08,070 --> 00:01:04,879 june 33 00:01:09,750 --> 00:01:08,080 the 600 000th graduate walked through 34 00:01:11,510 --> 00:01:09,760 the doors of space camp 35 00:01:12,870 --> 00:01:11,520 so that's exciting so again we have a 36 00:01:18,950 --> 00:01:12,880 special treat for you guys so we're 37 00:01:24,469 --> 00:01:21,910 hi i'm maggie swanian and i'm from 38 00:01:27,830 --> 00:01:24,479 duluth georgia 39 00:01:29,270 --> 00:01:27,840 my question is what are the 40 00:01:30,550 --> 00:01:29,280 what are all the 41 00:01:32,550 --> 00:01:30,560 um 42 00:01:35,350 --> 00:01:32,560 kind of like 43 00:01:37,990 --> 00:01:35,360 defects almost of being in space too 44 00:01:41,350 --> 00:01:38,000 long what happens to your body what 45 00:01:43,030 --> 00:01:41,360 happens if you're there too long or for 46 00:01:45,270 --> 00:01:43,040 a long period of time 47 00:01:46,550 --> 00:01:45,280 well that's a great question and it's 48 00:01:48,630 --> 00:01:46,560 actually very appropriate i'm a 49 00:01:50,230 --> 00:01:48,640 physiologist so that's like the thing 50 00:01:52,550 --> 00:01:50,240 i'm most interested in what happens to 51 00:01:54,870 --> 00:01:52,560 the human body when you go to space for 52 00:01:56,630 --> 00:01:54,880 a really long time and 53 00:01:58,469 --> 00:01:56,640 while it looks like a lot of fun to live 54 00:02:01,190 --> 00:01:58,479 in space and float around it looks like 55 00:02:03,190 --> 00:02:01,200 a like a great time it's not really that 56 00:02:05,429 --> 00:02:03,200 good for your body 57 00:02:07,749 --> 00:02:05,439 gravity is this force that we live with 58 00:02:10,150 --> 00:02:07,759 on earth all the time and it helps us 59 00:02:12,309 --> 00:02:10,160 maintain strong bones and muscles and a 60 00:02:15,270 --> 00:02:12,319 strong cardiovascular system in 61 00:02:18,150 --> 00:02:15,280 microgravity while those systems tend to 62 00:02:21,430 --> 00:02:18,160 decondition or get weaker so astronauts 63 00:02:24,390 --> 00:02:21,440 can lose bone mass bone strength 64 00:02:25,910 --> 00:02:24,400 muscle strength and mass and also their 65 00:02:29,110 --> 00:02:25,920 hearts get a little bit weaker among 66 00:02:31,270 --> 00:02:29,120 some other changes fortunately we have 67 00:02:33,350 --> 00:02:31,280 studied these changes and we know how to 68 00:02:35,910 --> 00:02:33,360 prevent them or prevent some of the 69 00:02:38,550 --> 00:02:35,920 changes that occur so astronauts have to 70 00:02:40,150 --> 00:02:38,560 exercise about two hours every day 71 00:02:42,630 --> 00:02:40,160 and we make sure that they eat very 72 00:02:44,550 --> 00:02:42,640 nutritious meals and so just like living 73 00:02:46,229 --> 00:02:44,560 here on earth it's important to exercise 74 00:02:48,830 --> 00:02:46,239 and eat well and that helps our 75 00:02:53,750 --> 00:02:48,840 astronauts helps you as 76 00:02:55,589 --> 00:02:53,760 well good question we have another one 77 00:02:59,750 --> 00:02:55,599 my name is emma hearn and i'm from 78 00:03:02,869 --> 00:02:59,760 snowville georgia and my question is 79 00:03:04,790 --> 00:03:02,879 what kind like when 80 00:03:07,350 --> 00:03:04,800 when did you decide you wanted to be an 81 00:03:08,869 --> 00:03:07,360 astronaut or work at nasa 82 00:03:10,869 --> 00:03:08,879 i think i was pretty young when i 83 00:03:12,869 --> 00:03:10,879 decided that that being an astronaut 84 00:03:14,949 --> 00:03:12,879 would be pretty cool and definitely 85 00:03:16,390 --> 00:03:14,959 working at nasa i might have been even 86 00:03:17,430 --> 00:03:16,400 younger than you 87 00:03:22,470 --> 00:03:17,440 and 88 00:03:24,470 --> 00:03:22,480 questions asked my parents how do i do 89 00:03:27,270 --> 00:03:24,480 this i talked to teachers 90 00:03:29,910 --> 00:03:27,280 and really anyone can can work at nasa 91 00:03:31,830 --> 00:03:29,920 any there's a variety of interests 92 00:03:33,350 --> 00:03:31,840 engineering and science and math of 93 00:03:35,589 --> 00:03:33,360 course help you 94 00:03:38,390 --> 00:03:35,599 open up many doors to career fields but 95 00:03:40,229 --> 00:03:38,400 nasa has people that are artists and 96 00:03:42,070 --> 00:03:40,239 lawyers as well 97 00:03:43,430 --> 00:03:42,080 but i knew pretty young that that i 98 00:03:45,509 --> 00:03:43,440 wanted to contribute to space 99 00:03:47,670 --> 00:03:45,519 exploration and 100 00:03:50,070 --> 00:03:47,680 i think it was in particular there was 101 00:03:52,630 --> 00:03:50,080 one very inspiring space shuttle mission 102 00:03:54,309 --> 00:03:52,640 to me it was sts-40 it was in the year 103 00:03:56,309 --> 00:03:54,319 1991 104 00:03:58,630 --> 00:03:56,319 i was still in high school and this 105 00:04:00,710 --> 00:03:58,640 mission was dedicated to studying space 106 00:04:02,390 --> 00:04:00,720 life sciences and i didn't know very 107 00:04:04,229 --> 00:04:02,400 much about space life sciences but i 108 00:04:06,550 --> 00:04:04,239 knew that i liked space and i knew that 109 00:04:08,229 --> 00:04:06,560 i liked biology and this particular 110 00:04:11,270 --> 00:04:08,239 space shuttle mission combined both of 111 00:04:13,270 --> 00:04:11,280 my interests and uh with that mission i 112 00:04:15,350 --> 00:04:13,280 decided i'm gonna go be a physiologist 113 00:04:16,949 --> 00:04:15,360 at nasa it took a couple years but here 114 00:04:18,870 --> 00:04:16,959 i am 115 00:04:23,990 --> 00:04:18,880 and we're very glad to have you here 116 00:04:29,510 --> 00:04:26,870 hi my name is cameron and 117 00:04:31,749 --> 00:04:29,520 i'm from atlanta georgia and i was 118 00:04:35,350 --> 00:04:31,759 wondering have you ever sent any other 119 00:04:36,790 --> 00:04:35,360 monkeys to space other than mrs baker 120 00:04:40,950 --> 00:04:36,800 and abel 121 00:04:42,469 --> 00:04:40,960 special monkeys but in fact a lot of 122 00:04:44,710 --> 00:04:42,479 different animals including other 123 00:04:46,870 --> 00:04:44,720 monkeys have flown in space in fact our 124 00:04:48,070 --> 00:04:46,880 early space program since we weren't 125 00:04:50,469 --> 00:04:48,080 really sure what would happen to the 126 00:04:52,469 --> 00:04:50,479 human body living in space we we had 127 00:04:54,629 --> 00:04:52,479 animals go first and kind of test the 128 00:04:56,629 --> 00:04:54,639 waters so to speak 129 00:04:58,870 --> 00:04:56,639 but in fact we've uh even on the 130 00:05:00,870 --> 00:04:58,880 international space station we have a 131 00:05:03,590 --> 00:05:00,880 brand new aquarium it's called the 132 00:05:05,430 --> 00:05:03,600 aquatic habitat and pretty soon we're 133 00:05:06,909 --> 00:05:05,440 going to have some fish on board so we 134 00:05:08,629 --> 00:05:06,919 can learn about 135 00:05:10,950 --> 00:05:08,639 multi-generational studies in other 136 00:05:12,150 --> 00:05:10,960 words send up some fish that are going 137 00:05:14,070 --> 00:05:12,160 to to 138 00:05:16,469 --> 00:05:14,080 have babies will study their babies and 139 00:05:18,390 --> 00:05:16,479 then their babies so we can learn uh 140 00:05:20,310 --> 00:05:18,400 developmentally what happens in 141 00:05:26,550 --> 00:05:20,320 microgravity but yeah lots of animals 142 00:05:30,710 --> 00:05:29,029 do we have another one 143 00:05:32,390 --> 00:05:30,720 hi i'm margaret ann 144 00:05:35,350 --> 00:05:32,400 and i'm from 145 00:05:38,550 --> 00:05:35,360 duluth georgia and my question is 146 00:05:39,749 --> 00:05:38,560 who controls the shuttle or the rocket 147 00:05:41,990 --> 00:05:39,759 is it you 148 00:05:44,070 --> 00:05:42,000 or the astronauts 149 00:05:45,830 --> 00:05:44,080 well i think a lot of the controlling of 150 00:05:47,110 --> 00:05:45,840 vehicles actually happens from the 151 00:05:49,350 --> 00:05:47,120 ground 152 00:05:51,110 --> 00:05:49,360 but amico do you want to chime in you 153 00:05:53,189 --> 00:05:51,120 know you work here in the international 154 00:05:55,350 --> 00:05:53,199 space station control room this this 155 00:05:57,670 --> 00:05:55,360 entire room is full of a team and and 156 00:05:59,990 --> 00:05:57,680 not only this team there are many other 157 00:06:03,110 --> 00:06:00,000 folks that are not inside this room that 158 00:06:04,469 --> 00:06:03,120 uh manage and work the systems that are 159 00:06:07,629 --> 00:06:04,479 the international space station which is 160 00:06:10,870 --> 00:06:07,639 now flying um 161 00:06:11,670 --> 00:06:10,880 230 mile i mean 30 miles above the earth 162 00:06:13,590 --> 00:06:11,680 and 163 00:06:15,990 --> 00:06:13,600 you know orbiting the earth what how 164 00:06:18,629 --> 00:06:16,000 many times a day nine years 16 times a 165 00:06:21,189 --> 00:06:18,639 day every 90 minutes yeah um of course 166 00:06:22,870 --> 00:06:21,199 the astronauts are on board you know 167 00:06:24,710 --> 00:06:22,880 most of the most of the rockets to make 168 00:06:27,029 --> 00:06:24,720 sure that all the systems are operating 169 00:06:29,510 --> 00:06:27,039 nominally and and uh of course they have 170 00:06:31,749 --> 00:06:29,520 to throw switches and certainly during 171 00:06:34,390 --> 00:06:31,759 landing they're they're having to make 172 00:06:36,550 --> 00:06:34,400 key inputs as well 173 00:06:38,550 --> 00:06:36,560 does that answer your question yep it's 174 00:06:40,550 --> 00:06:38,560 a team there's no uh 175 00:06:42,390 --> 00:06:40,560 no one person that manages all of that 176 00:06:45,029 --> 00:06:42,400 obviously and that's why teamwork is so 177 00:06:47,189 --> 00:06:45,039 very important to us here um and it's 178 00:06:49,830 --> 00:06:47,199 also something that you can probably use 179 00:06:52,230 --> 00:06:49,840 yourself as um you 180 00:06:54,390 --> 00:06:52,240 continue to work on your your 181 00:06:56,070 --> 00:06:54,400 your education career and then later in 182 00:06:58,629 --> 00:06:56,080 life in your career you'll see that 183 00:07:00,230 --> 00:06:58,639 teamwork is very valuable in all aspects 184 00:07:05,110 --> 00:07:00,240 of your life good question do we have 185 00:07:10,550 --> 00:07:08,390 um i'm kira hoskin from atlanta georgia 186 00:07:13,270 --> 00:07:10,560 um about how many people has america 187 00:07:15,430 --> 00:07:13,280 attempted to send up to space 188 00:07:18,950 --> 00:07:15,440 i think total there's been 189 00:07:21,270 --> 00:07:18,960 close to 500 people total who have been 190 00:07:23,909 --> 00:07:21,280 to space and i actually don't know the 191 00:07:26,790 --> 00:07:23,919 distribution of americans versus 192 00:07:28,309 --> 00:07:26,800 russians versus other countries 193 00:07:29,670 --> 00:07:28,319 but that's actually a pretty small 194 00:07:31,909 --> 00:07:29,680 number when you consider all of the 195 00:07:33,189 --> 00:07:31,919 human beings that have existed on our 196 00:07:35,589 --> 00:07:33,199 planet we've been sending people to 197 00:07:37,749 --> 00:07:35,599 space for 50 years now which which 198 00:07:40,230 --> 00:07:37,759 sounds like a long time probably to to 199 00:07:44,070 --> 00:07:40,240 uh to you but but that's that's just 200 00:07:46,230 --> 00:07:44,080 only been a very short time um so i 201 00:07:47,749 --> 00:07:46,240 think you know in the future our numbers 202 00:07:49,589 --> 00:07:47,759 are going to keep growing as as 203 00:07:50,869 --> 00:07:49,599 commercial space flight really comes on 204 00:07:52,710 --> 00:07:50,879 board in fact 205 00:07:55,110 --> 00:07:52,720 you know there's even been 206 00:07:57,350 --> 00:07:55,120 space flight participants or or tourists 207 00:07:59,510 --> 00:07:57,360 as a less commonly used term but there 208 00:08:02,230 --> 00:07:59,520 are companies right now who are who are 209 00:08:04,710 --> 00:08:02,240 working towards sending 210 00:08:06,390 --> 00:08:04,720 people who just buy a ticket to space 211 00:08:09,589 --> 00:08:06,400 and that's that's kind of a neat thing 212 00:08:11,749 --> 00:08:09,599 opening up this this once very very 213 00:08:13,029 --> 00:08:11,759 restricted area to to more people so i 214 00:08:16,070 --> 00:08:13,039 think i think more people are going to 215 00:08:17,589 --> 00:08:16,080 go to space uh very soon very good and 216 00:08:19,510 --> 00:08:17,599 as liz said i mean i don't really know 217 00:08:21,830 --> 00:08:19,520 that distribution is well i don't have 218 00:08:23,589 --> 00:08:21,840 my cheat sheet with me um however but i 219 00:08:24,950 --> 00:08:23,599 have talked with several of these folks 220 00:08:26,230 --> 00:08:24,960 who have flown to the international 221 00:08:28,390 --> 00:08:26,240 space station and i will tell you that 222 00:08:30,070 --> 00:08:28,400 they all recognize that it is a 223 00:08:31,430 --> 00:08:30,080 privilege and an honor to fly aboard the 224 00:08:33,909 --> 00:08:31,440 international space station but it is 225 00:08:36,469 --> 00:08:33,919 something that is obtainable and so if 226 00:08:37,909 --> 00:08:36,479 it's something that you aspire to do you 227 00:08:39,430 --> 00:08:37,919 know i would encourage you to continue 228 00:08:40,550 --> 00:08:39,440 with your studies that is always first 229 00:08:41,350 --> 00:08:40,560 and foremost 230 00:08:45,190 --> 00:08:41,360 um 231 00:08:47,670 --> 00:08:45,200 nasa it's very very important so 232 00:08:48,949 --> 00:08:47,680 continue with that and uh 233 00:08:51,269 --> 00:08:48,959 you'll you'll 234 00:08:53,829 --> 00:08:51,279 see your dreams absolutely you know one 235 00:08:55,509 --> 00:08:53,839 of one of the key aspects of space camp 236 00:08:58,310 --> 00:08:55,519 and one of the things that we learn at 237 00:09:00,070 --> 00:08:58,320 space camp is teamwork uh the importance 238 00:09:02,870 --> 00:09:00,080 of being a good follower as well as a 239 00:09:04,790 --> 00:09:02,880 good leader so those skills i i recall 240 00:09:07,670 --> 00:09:04,800 learning um pretty much for the first 241 00:09:09,910 --> 00:09:07,680 time at space camp and space academy 242 00:09:11,110 --> 00:09:09,920 and believe me those skills those little 243 00:09:13,030 --> 00:09:11,120 little bits that you take away from 244 00:09:14,949 --> 00:09:13,040 space camp they're with you for for the 245 00:09:17,670 --> 00:09:14,959 rest of your life i still draw upon 246 00:09:19,269 --> 00:09:17,680 experiences that i learned at space camp 247 00:09:23,110 --> 00:09:19,279 absolutely good question do we have 248 00:09:28,310 --> 00:09:25,030 hi i'm matt stone from lawrenceville 249 00:09:31,269 --> 00:09:28,320 georgia and my question is 250 00:09:34,630 --> 00:09:31,279 what is the longest period of time 251 00:09:36,949 --> 00:09:34,640 that an astronaut has been in space 252 00:09:40,150 --> 00:09:36,959 matt that's a good question the longest 253 00:09:43,110 --> 00:09:40,160 time at once like in one consecutive uh 254 00:09:45,870 --> 00:09:43,120 stay in space uh was actually uh done by 255 00:09:49,509 --> 00:09:45,880 a russian his name is valeri polyakov 256 00:09:51,910 --> 00:09:49,519 438 days so well over a year this 257 00:09:53,430 --> 00:09:51,920 gentleman stayed in space 258 00:09:55,110 --> 00:09:53,440 we have other we have many other 259 00:09:56,949 --> 00:09:55,120 astronauts and cosmonauts that when you 260 00:09:58,470 --> 00:09:56,959 add up their the number of stays that 261 00:10:00,389 --> 00:09:58,480 they've been in space have just been 262 00:10:03,269 --> 00:10:00,399 tremendous i think uh 263 00:10:05,269 --> 00:10:03,279 sergey krikalov has well over over a 264 00:10:06,069 --> 00:10:05,279 couple of years correct 265 00:10:10,069 --> 00:10:06,079 um 266 00:10:12,150 --> 00:10:10,079 a special day for the commander of the 267 00:10:14,790 --> 00:10:12,160 space station gennady padalka today 268 00:10:17,030 --> 00:10:14,800 actually marks his 700th cumulative time 269 00:10:19,269 --> 00:10:17,040 in space so yeah 270 00:10:21,430 --> 00:10:19,279 so several people who have have uh 271 00:10:26,470 --> 00:10:21,440 chalked up some time yeah good question 272 00:10:31,750 --> 00:10:29,030 yeah um my name is sarah 273 00:10:33,190 --> 00:10:31,760 and my question is that um if you could 274 00:10:36,790 --> 00:10:33,200 predict 275 00:10:38,230 --> 00:10:36,800 when humans could start going on mars 276 00:10:40,230 --> 00:10:38,240 you know 277 00:10:41,990 --> 00:10:40,240 we are learning every day 278 00:10:43,910 --> 00:10:42,000 on the international space station how 279 00:10:46,470 --> 00:10:43,920 to live and work in space efficiently 280 00:10:49,350 --> 00:10:46,480 and safely it's a very hard thing to do 281 00:10:52,389 --> 00:10:49,360 just keeping a vehicle in an operational 282 00:10:54,870 --> 00:10:52,399 state is very hard to do just yesterday 283 00:10:56,710 --> 00:10:54,880 we completed a very complex and very 284 00:10:59,430 --> 00:10:56,720 important spacewalk because we had an 285 00:11:01,190 --> 00:10:59,440 electrical problem on the space station 286 00:11:03,750 --> 00:11:01,200 so every day we're learning how to go 287 00:11:05,509 --> 00:11:03,760 how to live and work safely in space 288 00:11:08,230 --> 00:11:05,519 we're going to go to mars it's just a 289 00:11:10,870 --> 00:11:08,240 matter of time and national priority i 290 00:11:12,710 --> 00:11:10,880 think if we had to go soon we could we 291 00:11:15,190 --> 00:11:12,720 could go but there's still a lot we need 292 00:11:17,910 --> 00:11:15,200 to learn for example 293 00:11:19,990 --> 00:11:17,920 just human beings being in space for 294 00:11:22,949 --> 00:11:20,000 that long is really hard there are some 295 00:11:25,190 --> 00:11:22,959 challenges with radiation 296 00:11:26,389 --> 00:11:25,200 and so there's a lot we need to learn 297 00:11:28,630 --> 00:11:26,399 but 298 00:11:30,389 --> 00:11:28,640 i i i'm sure we're going to get there uh 299 00:11:36,310 --> 00:11:30,399 eventually 300 00:11:40,389 --> 00:11:37,990 hi my name is brandon and i live in 301 00:11:43,509 --> 00:11:40,399 lawrenceville georgia and my question is 302 00:11:45,190 --> 00:11:43,519 how would astronauts like 303 00:11:47,509 --> 00:11:45,200 move around and do 304 00:11:50,949 --> 00:11:47,519 regular everyday things with 305 00:11:52,230 --> 00:11:50,959 less much less gravity 306 00:11:53,670 --> 00:11:52,240 living on the international space 307 00:11:54,829 --> 00:11:53,680 station 308 00:11:56,710 --> 00:11:54,839 we say 309 00:11:58,870 --> 00:11:56,720 microgravity and 310 00:12:00,949 --> 00:11:58,880 you can see video i hope you you're able 311 00:12:02,710 --> 00:12:00,959 to watch nasa tv or some of the 312 00:12:05,910 --> 00:12:02,720 excellent footage we have on the 313 00:12:07,430 --> 00:12:05,920 nasa.gov website and youtube sites 314 00:12:08,949 --> 00:12:07,440 it looks like a blast it looks like fun 315 00:12:10,470 --> 00:12:08,959 it goes like this 316 00:12:12,069 --> 00:12:10,480 it's very slow motion 317 00:12:13,670 --> 00:12:12,079 yeah and all you need it's very 318 00:12:15,590 --> 00:12:13,680 effortless though if you want to move 319 00:12:17,990 --> 00:12:15,600 all the way across a room all you need 320 00:12:20,230 --> 00:12:18,000 to do is push gently on on the wall that 321 00:12:22,710 --> 00:12:20,240 you're near and you'll you'll float to 322 00:12:24,870 --> 00:12:22,720 the other side of the room so 323 00:12:26,629 --> 00:12:24,880 it looks like a lot of fun but it looks 324 00:12:29,190 --> 00:12:26,639 also looks pretty easy you can use your 325 00:12:31,190 --> 00:12:29,200 hands you can use your feet and you see 326 00:12:32,790 --> 00:12:31,200 them lifting very large heavy things 327 00:12:34,310 --> 00:12:32,800 that traditionally we would not be able 328 00:12:36,230 --> 00:12:34,320 to lift here on earth but also i know 329 00:12:38,629 --> 00:12:36,240 that at times it can complicate things 330 00:12:40,310 --> 00:12:38,639 and as liz had mentioned earlier about 331 00:12:42,389 --> 00:12:40,320 even just the uh you know if you imagine 332 00:12:44,310 --> 00:12:42,399 the gravity especially on our bodies you 333 00:12:47,190 --> 00:12:44,320 know just the simple movements that we 334 00:12:49,670 --> 00:12:47,200 make standing sitting and walking even 335 00:12:50,389 --> 00:12:49,680 though you don't have a you may not have 336 00:13:31,430 --> 00:12:50,399 a 337 00:13:32,710 --> 00:13:31,440 once once it's in orbit it just goes 338 00:13:35,030 --> 00:13:32,720 around and around the earth it's 339 00:13:37,190 --> 00:13:35,040 constantly falling though essentially 340 00:13:39,590 --> 00:13:37,200 when we when we talk about microgravity 341 00:13:41,269 --> 00:13:39,600 um we can you could also say free fall 342 00:13:42,790 --> 00:13:41,279 so the space station is always falling 343 00:13:45,110 --> 00:13:42,800 toward the earth but the great thing is 344 00:13:47,509 --> 00:13:45,120 the earth is also moving away from it so 345 00:13:49,829 --> 00:13:47,519 that's this neat balance between gravity 346 00:13:51,269 --> 00:13:49,839 pulling it down and and the force of the 347 00:13:52,790 --> 00:13:51,279 space station and the speed of the space 348 00:13:54,710 --> 00:13:52,800 station carrying it away it's it's a 349 00:13:57,350 --> 00:13:54,720 nice balance which which creates that 350 00:13:59,350 --> 00:13:57,360 micro gravity environment 351 00:14:00,710 --> 00:13:59,360 but the way it stays in space is is 352 00:14:02,470 --> 00:14:00,720 every once in a while we have to give it 353 00:14:04,949 --> 00:14:02,480 a little bit of a boost because there's 354 00:14:07,350 --> 00:14:04,959 just a little bit of friction out there 355 00:14:08,790 --> 00:14:07,360 just a few air molecules and everyone 356 00:14:10,629 --> 00:14:08,800 every time the space station hits one of 357 00:14:12,629 --> 00:14:10,639 those little air molecules it slows down 358 00:14:13,910 --> 00:14:12,639 ever so slightly 359 00:14:15,829 --> 00:14:13,920 so every once in a while we have to give 360 00:14:17,750 --> 00:14:15,839 the space station a little extra boost 361 00:14:20,550 --> 00:14:17,760 and it'll stay up there indefinitely 362 00:14:22,790 --> 00:14:20,560 until we're ready to take it down 363 00:14:26,150 --> 00:14:22,800 very good question very smart kids i can 364 00:14:28,470 --> 00:14:26,160 tell do we have another one 365 00:14:29,670 --> 00:14:28,480 hi my name is regan uh i'm from 366 00:14:31,110 --> 00:14:29,680 huntsville 367 00:14:32,550 --> 00:14:31,120 what are the qualifications of an 368 00:14:34,870 --> 00:14:32,560 astronaut 369 00:14:37,590 --> 00:14:34,880 hey reign well the qualifications for 370 00:14:40,150 --> 00:14:37,600 astronauts are that they have to have an 371 00:14:42,230 --> 00:14:40,160 advanced uh education so you've got to 372 00:14:43,430 --> 00:14:42,240 finish college get a bachelor of science 373 00:14:47,350 --> 00:14:43,440 degree 374 00:14:48,389 --> 00:14:47,360 in science math technology engineering 375 00:14:50,550 --> 00:14:48,399 and also 376 00:14:52,870 --> 00:14:50,560 usually a work experience the more 377 00:14:54,150 --> 00:14:52,880 breadth you have seems to be really 378 00:14:56,710 --> 00:14:54,160 valuable 379 00:14:59,509 --> 00:14:56,720 our astronauts have have a wide variety 380 00:15:00,790 --> 00:14:59,519 of skill sets and experience there are 381 00:15:03,110 --> 00:15:00,800 people who are 382 00:15:07,110 --> 00:15:03,120 marine biologists there are geologists 383 00:15:09,350 --> 00:15:07,120 there are engineers there are 384 00:15:11,750 --> 00:15:09,360 boy there are a whole variety there's 385 00:15:14,710 --> 00:15:11,760 medical doctors so it almost seems like 386 00:15:16,389 --> 00:15:14,720 any career that you choose um 387 00:15:18,870 --> 00:15:16,399 and if you want to be an astronaut be 388 00:15:20,629 --> 00:15:18,880 really good at what you do 389 00:15:22,470 --> 00:15:20,639 and enjoy what you're doing choose a 390 00:15:24,550 --> 00:15:22,480 field that that is something you enjoy 391 00:15:26,550 --> 00:15:24,560 and you'll probably excel if you're 392 00:15:27,430 --> 00:15:26,560 doing something that you really enjoy 393 00:15:32,470 --> 00:15:27,440 and 394 00:15:33,910 --> 00:15:32,480 there are people in the military who 395 00:15:36,870 --> 00:15:33,920 become astronauts because of their 396 00:15:37,749 --> 00:15:36,880 experience flying so there's a there's a 397 00:15:43,910 --> 00:15:37,759 great 398 00:15:49,269 --> 00:15:43,920 really high skill sets and abilities 399 00:15:54,790 --> 00:15:51,910 hi i'm emily i'm from georgia besides 400 00:15:57,430 --> 00:15:54,800 exercise what do astronauts do 401 00:15:59,269 --> 00:15:57,440 boy astronauts are very very busy when i 402 00:16:01,189 --> 00:15:59,279 said they exercise two hours a day 403 00:16:02,389 --> 00:16:01,199 that's crammed in the middle of a very 404 00:16:04,470 --> 00:16:02,399 busy day 405 00:16:06,230 --> 00:16:04,480 an average day in space usually wake uh 406 00:16:08,069 --> 00:16:06,240 wake up around six in the morning now 407 00:16:10,790 --> 00:16:08,079 when i say six in the morning that's uh 408 00:16:12,949 --> 00:16:10,800 uh on greenwich mean time so for houston 409 00:16:14,790 --> 00:16:12,959 and for huntsville that's about two in 410 00:16:16,230 --> 00:16:14,800 the morning right or one in the morning 411 00:16:17,829 --> 00:16:16,240 depending on if it's if it's central 412 00:16:20,310 --> 00:16:17,839 daylight or if it's daylight savings 413 00:16:21,829 --> 00:16:20,320 time or not um wake up at six have a 414 00:16:23,829 --> 00:16:21,839 little bit of time 415 00:16:25,670 --> 00:16:23,839 for hygiene eating breakfast getting 416 00:16:27,829 --> 00:16:25,680 ready for the day getting dressed and 417 00:16:29,269 --> 00:16:27,839 then right into a conference where you 418 00:16:31,670 --> 00:16:29,279 speak with ground controllers here in 419 00:16:33,749 --> 00:16:31,680 the space station control room and you 420 00:16:35,269 --> 00:16:33,759 kind of talk about what's going to go go 421 00:16:37,189 --> 00:16:35,279 on for the day and then you get right 422 00:16:39,110 --> 00:16:37,199 into doing science experiments 423 00:16:40,230 --> 00:16:39,120 maintenance of the space station and it 424 00:16:42,870 --> 00:16:40,240 takes a lot of work just to keep the 425 00:16:44,710 --> 00:16:42,880 space station going a variety of space 426 00:16:47,430 --> 00:16:44,720 station experiments you may be working 427 00:16:49,030 --> 00:16:47,440 with flame and combustion one minute and 428 00:16:50,790 --> 00:16:49,040 then the next minute taking an 429 00:16:53,350 --> 00:16:50,800 ultrasound or the next hour taking an 430 00:16:55,910 --> 00:16:53,360 ultrasound images of your heart and then 431 00:16:58,230 --> 00:16:55,920 you may go 10 to the aquatic habitat 432 00:17:00,790 --> 00:16:58,240 where you may have some fish 433 00:17:02,470 --> 00:17:00,800 and then have a quick lunch usually keep 434 00:17:03,990 --> 00:17:02,480 working throughout the day 435 00:17:06,150 --> 00:17:04,000 maybe have another conference with a 436 00:17:09,189 --> 00:17:06,160 doctor or the flight director just to 437 00:17:10,710 --> 00:17:09,199 keep tabs on how things are going 438 00:17:12,630 --> 00:17:10,720 the day usually ends with another 439 00:17:13,909 --> 00:17:12,640 conference where i talk about what 440 00:17:15,429 --> 00:17:13,919 happened during the day with the ground 441 00:17:16,870 --> 00:17:15,439 controllers talk maybe about what's 442 00:17:19,029 --> 00:17:16,880 going to happen the next day what worked 443 00:17:20,549 --> 00:17:19,039 what didn't work 444 00:17:22,870 --> 00:17:20,559 and in the middle there i said you know 445 00:17:24,549 --> 00:17:22,880 you had your two hours of exercise and 446 00:17:26,309 --> 00:17:24,559 then and then you have a little bit of 447 00:17:28,789 --> 00:17:26,319 free time and then and then bed and 448 00:17:29,909 --> 00:17:28,799 that's a very very busy day the 449 00:17:32,390 --> 00:17:29,919 astronauts 450 00:17:35,669 --> 00:17:32,400 have a tremendous workload and almost 451 00:17:38,150 --> 00:17:35,679 every minute is accounted for 452 00:17:39,830 --> 00:17:38,160 very busy day and it's every day every 453 00:17:41,190 --> 00:17:39,840 day they get a little time to talk to 454 00:17:43,350 --> 00:17:41,200 their families on the weekends and they 455 00:17:45,350 --> 00:17:43,360 can make a phone call here and there 456 00:17:47,029 --> 00:17:45,360 but but otherwise they're extremely busy 457 00:17:48,710 --> 00:17:47,039 there's six people on the international 458 00:17:50,950 --> 00:17:48,720 space station and they're working very 459 00:17:53,029 --> 00:17:50,960 hard so you can imagine how much work is 460 00:17:54,870 --> 00:17:53,039 getting done 461 00:17:56,630 --> 00:17:54,880 very good question and i think we have 462 00:18:00,070 --> 00:17:56,640 time for another one do we have another 463 00:18:04,390 --> 00:18:01,430 my name is abigail and i'm from 464 00:18:05,510 --> 00:18:04,400 huntsville alabama and i was wondering 465 00:18:07,510 --> 00:18:05,520 um 466 00:18:08,549 --> 00:18:07,520 have there ever been any problems in 467 00:18:10,070 --> 00:18:08,559 with this 468 00:18:11,909 --> 00:18:10,080 rocket ship or anything that happened 469 00:18:14,710 --> 00:18:11,919 that wasn't supposed to happen 470 00:18:16,470 --> 00:18:14,720 absolutely space space travel abigail is 471 00:18:18,390 --> 00:18:16,480 is is difficult we've been doing it for 472 00:18:20,710 --> 00:18:18,400 50 years we're still learning 473 00:18:22,549 --> 00:18:20,720 there have absolutely been some 474 00:18:24,310 --> 00:18:22,559 challenges to overcome we've had we've 475 00:18:27,029 --> 00:18:24,320 had some accidents along the way we've 476 00:18:28,710 --> 00:18:27,039 lost some people and that's very hard 477 00:18:30,390 --> 00:18:28,720 it's something that we accept in the 478 00:18:31,750 --> 00:18:30,400 space business though 479 00:18:33,909 --> 00:18:31,760 we go into this knowing that we're 480 00:18:36,470 --> 00:18:33,919 pushing the very boundaries of human 481 00:18:38,070 --> 00:18:36,480 ability and when you're exploring and 482 00:18:39,350 --> 00:18:38,080 you're pushing boundaries 483 00:18:41,990 --> 00:18:39,360 there's going to be some losses and 484 00:18:44,230 --> 00:18:42,000 we've had some very sad losses 485 00:18:46,230 --> 00:18:44,240 but it also gives nasa an opportunity 486 00:18:47,909 --> 00:18:46,240 and our energy and our international 487 00:18:49,909 --> 00:18:47,919 partners to really shine too because 488 00:18:51,190 --> 00:18:49,919 when you overcome a challenge it really 489 00:18:53,029 --> 00:18:51,200 feels good 490 00:18:55,270 --> 00:18:53,039 like i mentioned earlier just yesterday 491 00:18:57,029 --> 00:18:55,280 there was a very very difficult eva 492 00:18:59,430 --> 00:18:57,039 that's a spacewalk 493 00:19:01,510 --> 00:18:59,440 that was performed that fixed a really 494 00:19:03,750 --> 00:19:01,520 serious problem with power 495 00:19:06,070 --> 00:19:03,760 that it was basically cut the space 496 00:19:09,190 --> 00:19:06,080 station's power by about half 497 00:19:11,270 --> 00:19:09,200 essentially and so every day we're 498 00:19:12,789 --> 00:19:11,280 having challenges almost every day and 499 00:19:14,789 --> 00:19:12,799 when we overcome those challenges it 500 00:19:16,710 --> 00:19:14,799 feels really good and it helps us to 501 00:19:18,470 --> 00:19:16,720 learn so that we can do better in the 502 00:19:20,789 --> 00:19:18,480 future 503 00:19:22,870 --> 00:19:20,799 and maybe one day get to mars 504 00:19:27,270 --> 00:19:22,880 i believe it we will 505 00:19:30,710 --> 00:19:29,270 what was the first mission they ever 506 00:19:32,390 --> 00:19:30,720 worked on 507 00:19:35,590 --> 00:19:32,400 me personally 508 00:19:38,070 --> 00:19:35,600 i was doing research as a college 509 00:19:40,630 --> 00:19:38,080 student the first mission i helped with 510 00:19:41,510 --> 00:19:40,640 was sts-84 511 00:19:43,830 --> 00:19:41,520 and 512 00:19:45,430 --> 00:19:43,840 this experiment actually 513 00:19:47,270 --> 00:19:45,440 went to the mir space station it 514 00:19:49,190 --> 00:19:47,280 launched on the space shuttle went to 515 00:19:51,350 --> 00:19:49,200 the mir space station and stayed there 516 00:19:54,070 --> 00:19:51,360 with astronaut mike foale and it was a 517 00:19:56,470 --> 00:19:54,080 little little uh experiment that studied 518 00:20:00,070 --> 00:19:56,480 circadian rhythms or or sleep and how 519 00:20:02,950 --> 00:20:00,080 well astronauts may um may learn uh how 520 00:20:04,789 --> 00:20:02,960 to how to sleep better and how light 521 00:20:06,549 --> 00:20:04,799 affects how well they sleep and actually 522 00:20:07,909 --> 00:20:06,559 the experiment was on little beetles we 523 00:20:11,110 --> 00:20:07,919 launched little beetles and little 524 00:20:12,630 --> 00:20:11,120 miniature um holding canisters and that 525 00:20:14,230 --> 00:20:12,640 was the first the first mission that i 526 00:20:16,310 --> 00:20:14,240 worked on and i've been working ever 527 00:20:18,950 --> 00:20:16,320 since on a whole bunch of missions it's 528 00:20:20,549 --> 00:20:18,960 it's it's been a tremendous honor and i 529 00:20:22,950 --> 00:20:20,559 love doing it every day 530 00:20:23,750 --> 00:20:22,960 and if it's something you want to do 531 00:20:25,430 --> 00:20:23,760 just 532 00:20:28,070 --> 00:20:25,440 keep working at it it's sometimes 533 00:20:30,870 --> 00:20:28,080 there's obstacles to overcome in school 534 00:20:33,270 --> 00:20:30,880 or in your personal life 535 00:20:35,029 --> 00:20:33,280 i was very very happy and lucky that i 536 00:20:38,789 --> 00:20:35,039 knew what i wanted to do so i just set 537 00:20:44,310 --> 00:20:38,799 my goal and i worked toward it steadily 538 00:20:49,909 --> 00:20:47,430 my name is gemin and i'm from ohio and 539 00:20:52,230 --> 00:20:49,919 how did the people know where to land 540 00:20:53,110 --> 00:20:52,240 curiosity on mars 541 00:20:54,470 --> 00:20:53,120 wow 542 00:20:56,149 --> 00:20:54,480 i don't even know the answer to that 543 00:20:58,549 --> 00:20:56,159 question but i can guess 544 00:21:00,830 --> 00:20:58,559 and i think they chose a place on mars 545 00:21:03,110 --> 00:21:00,840 that was really interesting to them 546 00:21:04,870 --> 00:21:03,120 geologically but i am definitely not the 547 00:21:06,630 --> 00:21:04,880 right person to ask there's so many 548 00:21:09,029 --> 00:21:06,640 things to learn about nasa and we can't 549 00:21:10,710 --> 00:21:09,039 possibly all know all the answers 550 00:21:12,230 --> 00:21:10,720 and i'm certainly not the person you ask 551 00:21:14,830 --> 00:21:12,240 either i'm sorry i don't know the answer 552 00:21:16,789 --> 00:21:14,840 to that but you can go to 553 00:21:18,390 --> 00:21:16,799 www.nasa.gov there's a ton of 554 00:21:20,470 --> 00:21:18,400 information there 555 00:21:22,149 --> 00:21:20,480 obviously there's a ton of information 556 00:21:23,909 --> 00:21:22,159 about mars curiosity there are several 557 00:21:25,669 --> 00:21:23,919 people who tweet 558 00:21:27,029 --> 00:21:25,679 on twitter so if any of you guys are on 559 00:21:29,590 --> 00:21:27,039 twitter 560 00:21:30,549 --> 00:21:29,600 go there i would say follow the flight 561 00:21:31,830 --> 00:21:30,559 director 562 00:21:34,310 --> 00:21:31,840 mohawk guy

information about what 566 00:21:42,710 --> 00:21:40,080 exactly is going on with that mars rover 567 00:21:49,830 --> 00:21:42,720 um there on mars and in the that landed 568 00:21:55,830 --> 00:21:52,789 hi i'm nicole i'm from stone mountain 569 00:21:58,310 --> 00:21:55,840 georgia and i was wondering how it felt 570 00:22:00,470 --> 00:21:58,320 when you had a successful landing from 571 00:22:02,390 --> 00:22:00,480 either a human or an animal and like 572 00:22:04,630 --> 00:22:02,400 they came back and they went there with 573 00:22:06,710 --> 00:22:04,640 no problems 574 00:22:08,789 --> 00:22:06,720 well that that mission that i mentioned 575 00:22:11,110 --> 00:22:08,799 earlier sts-84 being that it was the 576 00:22:13,990 --> 00:22:11,120 first mission that uh that i worked on 577 00:22:15,590 --> 00:22:14,000 personally um it was tremendous i had 578 00:22:18,149 --> 00:22:15,600 watched a lot of space shuttle missions 579 00:22:20,149 --> 00:22:18,159 launched before that as and and just 580 00:22:21,990 --> 00:22:20,159 watching those missions happen very 581 00:22:24,310 --> 00:22:22,000 exciting and thrilling but when you have 582 00:22:26,149 --> 00:22:24,320 a part when you're playing a part in a 583 00:22:27,909 --> 00:22:26,159 small role 584 00:22:30,789 --> 00:22:27,919 it really gives you tremendous 585 00:22:32,630 --> 00:22:30,799 satisfaction everyone here at nasa 586 00:22:34,870 --> 00:22:32,640 pretty much everyone has a very small 587 00:22:36,630 --> 00:22:34,880 role for the most part when you add up 588 00:22:38,950 --> 00:22:36,640 all those people working together you 589 00:22:41,029 --> 00:22:38,960 can do tremendous things and you know 590 00:22:41,990 --> 00:22:41,039 the astronauts they're just the most 591 00:22:45,270 --> 00:22:42,000 visible 592 00:22:46,870 --> 00:22:45,280 pieces of us of a mission um but there's 593 00:22:48,549 --> 00:22:46,880 there's thousands of people working 594 00:22:50,870 --> 00:22:48,559 every day to make sure that we're 595 00:22:53,270 --> 00:22:50,880 successful and all those thousands of 596 00:22:56,070 --> 00:22:54,470 i get tremendous 597 00:22:58,070 --> 00:22:56,080 self-satisfaction knowing that i'm 598 00:23:00,070 --> 00:22:58,080 helping just the littlest bit and that 599 00:23:02,390 --> 00:23:00,080 that makes me feel really good it's it 600 00:23:04,470 --> 00:23:02,400 just makes you feel just good inside and 601 00:23:08,070 --> 00:23:04,480 i think that's a in overall the 602 00:23:10,149 --> 00:23:08,080 consensus here i honestly um at landing 603 00:23:12,390 --> 00:23:10,159 you know i've seen many many missions 604 00:23:14,310 --> 00:23:12,400 land and i can tell you every time we 605 00:23:16,390 --> 00:23:14,320 land and we have a successful mission i 606 00:23:17,350 --> 00:23:16,400 get goosebumps i get excited it doesn't 607 00:23:19,110 --> 00:23:17,360 change 608 00:23:21,029 --> 00:23:19,120 i never become desensitized well i think 609 00:23:21,830 --> 00:23:21,039 yeah yeah i've seen it once i've seen it 610 00:23:23,270 --> 00:23:21,840 all 611 00:23:25,590 --> 00:23:23,280 every mission is different and every 612 00:23:27,909 --> 00:23:25,600 mission is special and everyone involved 613 00:23:29,909 --> 00:23:27,919 in that is very special and unique and 614 00:23:32,230 --> 00:23:29,919 important to us as well as the mission 615 00:23:33,990 --> 00:23:32,240 as well and um so yeah it's very 616 00:23:36,390 --> 00:23:34,000 important to us and i think of course we 617 00:23:37,110 --> 00:23:36,400 feel elated when we know that we nailed 618 00:23:47,350 --> 00:23:37,120 it 619 00:23:49,350 --> 00:23:47,360 and i was wondering about how many 620 00:23:51,510 --> 00:23:49,360 different types of animals have you sent 621 00:23:54,870 --> 00:23:51,520 up to space 622 00:23:56,789 --> 00:23:54,880 well personally let's talk generically 623 00:23:59,669 --> 00:23:56,799 boy there's been fish there's been 624 00:24:02,390 --> 00:23:59,679 monkeys there's been insects 625 00:24:04,710 --> 00:24:02,400 there's been mice and rats 626 00:24:06,470 --> 00:24:04,720 i would say at least 10 probably 627 00:24:09,190 --> 00:24:06,480 different types of animals have been in 628 00:24:11,590 --> 00:24:09,200 space and and we can we can study them 629 00:24:13,830 --> 00:24:11,600 and learn from them as well as from our 630 00:24:15,029 --> 00:24:13,840 astronauts um 631 00:24:17,029 --> 00:24:15,039 so i think 632 00:24:18,390 --> 00:24:17,039 yeah quite a few critters have gone up 633 00:24:20,950 --> 00:24:18,400 into space so 634 00:24:22,950 --> 00:24:20,960 along with our people quitters 635 00:24:24,390 --> 00:24:22,960 i think uh that's about all the
