1 00:00:04,390 --> 00:00:02,230 good morning welcome to the space 2 00:00:06,070 --> 00:00:04,400 station flight control room i'm brandi 3 00:00:08,070 --> 00:00:06,080 dean with nasa public affairs office and 4 00:00:10,629 --> 00:00:08,080 i'm joined today by lisborne who is with 5 00:00:11,749 --> 00:00:10,639 the space station program science office 6 00:00:12,950 --> 00:00:11,759 and uh we are going to be joined 7 00:00:14,549 --> 00:00:12,960 remotely 8 00:00:16,230 --> 00:00:14,559 by students from fayette academy in 9 00:00:18,310 --> 00:00:16,240 somerville tennessee and i believe they 10 00:00:23,029 --> 00:00:18,320 have some questions for us can you all 11 00:00:25,830 --> 00:00:24,390 all right well tell us a little bit 12 00:00:30,550 --> 00:00:25,840 about you and then we'll get started on 13 00:00:34,950 --> 00:00:32,790 good morning i'm the principal research 14 00:00:37,270 --> 00:00:34,960 investigator for the student spaceflight 15 00:00:38,869 --> 00:00:37,280 experiments research project that was 16 00:00:41,190 --> 00:00:38,879 selected to go to the international 17 00:00:43,830 --> 00:00:41,200 space station in october 18 00:00:46,549 --> 00:00:43,840 our research project focuses on the 19 00:00:49,750 --> 00:00:46,559 reishi mushroom's effect on chronic 20 00:00:52,709 --> 00:00:49,760 myeloid leukemia's biological model 21 00:00:54,630 --> 00:00:52,719 e coli and microgravity 22 00:00:56,869 --> 00:00:54,640 my question is 23 00:00:58,950 --> 00:00:56,879 what type of research has been done in 24 00:01:00,950 --> 00:00:58,960 recent years on the international space 25 00:01:03,430 --> 00:01:00,960 station that will help to make it 26 00:01:05,910 --> 00:01:03,440 possible to keep people in space for 27 00:01:07,429 --> 00:01:05,920 prolonged periods of time with minimal 28 00:01:09,750 --> 00:01:07,439 negative effects 29 00:01:11,590 --> 00:01:09,760 on the space travelers 30 00:01:14,310 --> 00:01:11,600 well first of all i want to say hello 31 00:01:16,310 --> 00:01:14,320 and greetings uh brandon and i had a 32 00:01:17,749 --> 00:01:16,320 communication with butch wilmore who's 33 00:01:19,910 --> 00:01:17,759 going to be on orbit when your 34 00:01:21,350 --> 00:01:19,920 experiment gets there and he wasn't able 35 00:01:23,190 --> 00:01:21,360 to be here today he's actually on his 36 00:01:24,789 --> 00:01:23,200 way to russia but he did say that he's 37 00:01:27,030 --> 00:01:24,799 going to take real good care of your 38 00:01:28,710 --> 00:01:27,040 experiment so that's pretty cool i also 39 00:01:31,590 --> 00:01:28,720 think it's fantastic that you guys are 40 00:01:32,789 --> 00:01:31,600 participating in this space in the ssep 41 00:01:35,190 --> 00:01:32,799 program 42 00:01:37,030 --> 00:01:35,200 it's it's fantastic to see young people 43 00:01:39,270 --> 00:01:37,040 be interested in science and then 44 00:01:41,350 --> 00:01:39,280 propose an experiment and i'll tell you 45 00:01:43,429 --> 00:01:41,360 what if i was your age and i was able to 46 00:01:45,190 --> 00:01:43,439 have an experiment on the space station 47 00:01:46,870 --> 00:01:45,200 i would just i would be over the moon so 48 00:01:48,710 --> 00:01:46,880 i'm i'm proud of you guys thanks very 49 00:01:50,789 --> 00:01:48,720 much for participating and i hope you 50 00:01:52,550 --> 00:01:50,799 get excellent results 51 00:01:54,469 --> 00:01:52,560 now to answer your question 52 00:01:56,789 --> 00:01:54,479 so we've actually done a tremendous 53 00:01:58,789 --> 00:01:56,799 amount of work studying what happens to 54 00:02:00,310 --> 00:01:58,799 the human body in space and some of 55 00:02:03,109 --> 00:02:00,320 those changes that happen to the human 56 00:02:06,230 --> 00:02:03,119 body they're not very good for us 57 00:02:08,469 --> 00:02:06,240 so we try and mitigate those changes and 58 00:02:10,389 --> 00:02:08,479 some of those changes include some of 59 00:02:13,190 --> 00:02:10,399 them you may have heard of astronauts 60 00:02:16,070 --> 00:02:13,200 tend to lose bone or bone density while 61 00:02:18,710 --> 00:02:16,080 they're in space the lack of 62 00:02:20,710 --> 00:02:18,720 the loading of gravity is removed so 63 00:02:22,869 --> 00:02:20,720 microgravity is what we say the 64 00:02:24,869 --> 00:02:22,879 astronauts are living in in space and 65 00:02:27,270 --> 00:02:24,879 microgravity 66 00:02:29,589 --> 00:02:27,280 causes your bones to get weaker it's 67 00:02:31,750 --> 00:02:29,599 also true for your cardiovascular system 68 00:02:33,750 --> 00:02:31,760 and your muscles and even the immune 69 00:02:35,750 --> 00:02:33,760 system gets weaker so 70 00:02:38,309 --> 00:02:35,760 living in space isn't all that great for 71 00:02:40,550 --> 00:02:38,319 the human body fortunately we've learned 72 00:02:42,630 --> 00:02:40,560 a lot over the 50 some odd years that 73 00:02:44,309 --> 00:02:42,640 we've been doing space flight and we've 74 00:02:45,910 --> 00:02:44,319 learned to mitigate a lot of those 75 00:02:48,869 --> 00:02:45,920 changes so 76 00:02:51,990 --> 00:02:48,879 astronauts exercise a lot on orbit we 77 00:02:53,509 --> 00:02:52,000 allot them about two hours a day to 78 00:02:55,430 --> 00:02:53,519 to work out and that includes a little 79 00:02:56,710 --> 00:02:55,440 bit of time for hygiene and getting 80 00:02:58,710 --> 00:02:56,720 changed 81 00:03:01,270 --> 00:02:58,720 but that exercise helps them maintain 82 00:03:03,910 --> 00:03:01,280 bone strength and cardiovascular fitness 83 00:03:06,229 --> 00:03:03,920 and muscle strength and has some other 84 00:03:07,670 --> 00:03:06,239 beneficial effects for just improving 85 00:03:10,229 --> 00:03:07,680 their mood and it's kind of a stress 86 00:03:12,309 --> 00:03:10,239 relief as well so that's that's kind of 87 00:03:13,990 --> 00:03:12,319 a high level overview of of what we do 88 00:03:16,229 --> 00:03:14,000 to keep our astronauts safe while 89 00:03:20,550 --> 00:03:16,239 they're in space 90 00:03:20,560 --> 00:03:24,710 hi um 91 00:03:29,030 --> 00:03:25,830 i wanted to know if you've ever 92 00:03:31,110 --> 00:03:29,040 performed any uh research on metabolism 93 00:03:32,789 --> 00:03:31,120 if they had any effect with the 94 00:03:35,030 --> 00:03:32,799 anti-gravity 95 00:03:37,270 --> 00:03:35,040 and if you have what kind of research 96 00:03:39,910 --> 00:03:37,280 experiments have you done 97 00:03:41,670 --> 00:03:39,920 well when i was a university student and 98 00:03:44,710 --> 00:03:41,680 then in grad school i was really 99 00:03:46,630 --> 00:03:44,720 interested in metabolism and metabolism 100 00:03:49,589 --> 00:03:46,640 is sort of how your body controls how 101 00:03:52,710 --> 00:03:49,599 much energy it takes in through the form 102 00:03:55,030 --> 00:03:52,720 of calories so eating food how much 103 00:03:58,869 --> 00:03:55,040 energy you expend 104 00:04:01,350 --> 00:03:58,879 so daily metabolic rate and exercise and 105 00:04:03,750 --> 00:04:01,360 how those things balance out to maintain 106 00:04:05,910 --> 00:04:03,760 our body mass and i was interested if 107 00:04:08,630 --> 00:04:05,920 going to a different gravity level would 108 00:04:11,030 --> 00:04:08,640 affect metabolism different gravity all 109 00:04:13,110 --> 00:04:11,040 the way from maybe more gravity than is 110 00:04:16,069 --> 00:04:13,120 on earth to less gravity than is on 111 00:04:18,629 --> 00:04:16,079 earth and so i actually was able to 112 00:04:20,629 --> 00:04:18,639 perform some experiments 113 00:04:23,189 --> 00:04:20,639 here on earth using a centrifuge to 114 00:04:26,150 --> 00:04:23,199 expose my subjects to more than one 115 00:04:29,110 --> 00:04:26,160 gravity actually two times earth gravity 116 00:04:31,830 --> 00:04:29,120 and i found that not surprisingly that 117 00:04:34,469 --> 00:04:31,840 caused more energy expenditure so there 118 00:04:36,870 --> 00:04:34,479 was a little more uh intake requirement 119 00:04:39,030 --> 00:04:36,880 the more energy you expend the more food 120 00:04:41,110 --> 00:04:39,040 you have to eat to maintain 121 00:04:43,909 --> 00:04:41,120 normal energy balance 122 00:04:45,830 --> 00:04:43,919 and the reverse was true in space sort 123 00:04:48,469 --> 00:04:45,840 of it wasn't exactly what i wanted was 124 00:04:50,790 --> 00:04:48,479 hoping to find so my hypothesis was not 125 00:04:52,710 --> 00:04:50,800 exactly supported but that's kind of one 126 00:04:53,749 --> 00:04:52,720 of the cool things about science you ask 127 00:04:56,230 --> 00:04:53,759 a question 128 00:04:58,070 --> 00:04:56,240 you form a hypothesis what you think the 129 00:05:00,070 --> 00:04:58,080 answer is going to be then you perform 130 00:05:01,430 --> 00:05:00,080 the experiment and sometimes you're 131 00:05:03,909 --> 00:05:01,440 right and sometimes you're wrong but 132 00:05:05,990 --> 00:05:03,919 either way you have learned something 133 00:05:08,710 --> 00:05:06,000 and so i had that experience and that 134 00:05:11,270 --> 00:05:08,720 opportunity when i got to college and 135 00:05:13,749 --> 00:05:11,280 part of my um part of my experiment was 136 00:05:15,909 --> 00:05:13,759 done on a space shuttle mission it was 137 00:05:18,150 --> 00:05:15,919 sts-90 138 00:05:20,310 --> 00:05:18,160 it was a neurolab mission it was called 139 00:05:22,230 --> 00:05:20,320 neurolab mission and so that was a great 140 00:05:23,990 --> 00:05:22,240 opportunity for me you guys are getting 141 00:05:26,150 --> 00:05:24,000 to do the same thing now when you're in 142 00:05:27,749 --> 00:05:26,160 high school so you guys are you guys are 143 00:05:28,950 --> 00:05:27,759 well ahead of the game 144 00:05:30,469 --> 00:05:28,960 sounds like you're the perfect person to 145 00:05:33,830 --> 00:05:30,479 answer that question too 146 00:05:36,469 --> 00:05:33,840 good job so uh next question 147 00:05:38,629 --> 00:05:36,479 hi arch school was mentored by dr rafael 148 00:05:40,950 --> 00:05:38,639 collins underwood a researcher from 149 00:05:42,469 --> 00:05:40,960 saint jude children's research hospital 150 00:05:44,390 --> 00:05:42,479 during our student space flight 151 00:05:46,310 --> 00:05:44,400 experience program my research team 152 00:05:48,070 --> 00:05:46,320 designed a project that focused on what 153 00:05:50,150 --> 00:05:48,080 effect would microgravity have on the 154 00:05:51,749 --> 00:05:50,160 growth rate of chronic model of leukemia 155 00:05:53,110 --> 00:05:51,759 we were one of our school's finalists 156 00:05:55,110 --> 00:05:53,120 but our experiment will not be going to 157 00:05:56,309 --> 00:05:55,120 the international space station do you 158 00:05:58,230 --> 00:05:56,319 know that there has been research on the 159 00:05:59,670 --> 00:05:58,240 iss that focuses on the effect of 160 00:06:01,749 --> 00:05:59,680 microgravity on the growth rate of 161 00:06:04,230 --> 00:06:01,759 lithium cells 162 00:06:06,070 --> 00:06:04,240 so first of all let me say you know the 163 00:06:07,749 --> 00:06:06,080 fact that your exact experiment isn't 164 00:06:09,590 --> 00:06:07,759 going to make it to the space station 165 00:06:11,270 --> 00:06:09,600 don't let that discourage you the whole 166 00:06:13,270 --> 00:06:11,280 fact that you came up with an idea and 167 00:06:15,590 --> 00:06:13,280 proposed it to nasa 168 00:06:17,270 --> 00:06:15,600 is something to be very proud of 169 00:06:19,110 --> 00:06:17,280 it certainly doesn't preclude you from 170 00:06:21,189 --> 00:06:19,120 being involved in the future and i hope 171 00:06:23,189 --> 00:06:21,199 that you'll consider to do that 172 00:06:25,430 --> 00:06:23,199 research and science is something that 173 00:06:27,590 --> 00:06:25,440 is so much fun and i'm again i'm proud 174 00:06:30,070 --> 00:06:27,600 of you all of you for being involved and 175 00:06:32,710 --> 00:06:30,080 asking a question please don't ever lose 176 00:06:33,510 --> 00:06:32,720 that curiosity it it keeps it keeps us 177 00:06:36,230 --> 00:06:33,520 all 178 00:06:38,710 --> 00:06:36,240 scientist 179 00:06:42,070 --> 00:06:38,720 so to answer your question about 180 00:06:44,070 --> 00:06:42,080 leukemia cells in space i think a lot of 181 00:06:46,550 --> 00:06:44,080 examples have been flown a lot of cells 182 00:06:49,510 --> 00:06:46,560 have been flown in microgravity in space 183 00:06:52,230 --> 00:06:49,520 including leukemia cells and you asked 184 00:06:54,790 --> 00:06:52,240 specifically about growth rate 185 00:06:57,029 --> 00:06:54,800 from the literature that i'm aware of i 186 00:06:59,589 --> 00:06:57,039 think we've actually seen that growth 187 00:07:02,230 --> 00:06:59,599 rate of some leukemia cells is arrested 188 00:07:04,309 --> 00:07:02,240 or stopped in microgravity that doesn't 189 00:07:06,710 --> 00:07:04,319 mean it's always going to be true or 190 00:07:09,189 --> 00:07:06,720 it's going to be true for all cell lines 191 00:07:11,270 --> 00:07:09,199 so we still have a lot to learn but from 192 00:07:13,749 --> 00:07:11,280 what i'm familiar with we have seen 193 00:07:15,670 --> 00:07:13,759 microgravity affect 194 00:07:16,390 --> 00:07:15,680 multiple aspects of 195 00:07:19,830 --> 00:07:16,400 cell 196 00:07:22,230 --> 00:07:19,840 life growth cytoskeletal activity 197 00:07:25,029 --> 00:07:22,240 meiosis or separation and division of 198 00:07:28,070 --> 00:07:25,039 cells so we've seen a lot of changes 199 00:07:29,589 --> 00:07:28,080 but we still have a lot to learn so so i 200 00:07:31,110 --> 00:07:29,599 save that experiment and propose it 201 00:07:32,550 --> 00:07:31,120 another time 202 00:07:33,749 --> 00:07:32,560 that's fascinating y'all are asking 203 00:07:37,350 --> 00:07:33,759 great questions i think we're ready for 204 00:07:41,749 --> 00:07:39,270 hi my name is bowman 205 00:07:46,469 --> 00:07:41,759 i want to know would the lack of gravity 206 00:07:49,510 --> 00:07:48,390 so that's a fascinating question and 207 00:07:52,070 --> 00:07:49,520 it's been 208 00:07:54,309 --> 00:07:52,080 proposed and it's actually been flown on 209 00:07:56,309 --> 00:07:54,319 a several space flight experiments 210 00:07:59,110 --> 00:07:56,319 chicken eggs quail eggs and different 211 00:08:01,589 --> 00:07:59,120 kinds of bird eggs and 212 00:08:04,309 --> 00:08:01,599 i think that our findings have been a 213 00:08:06,710 --> 00:08:04,319 little bit inconclusive but for the most 214 00:08:09,350 --> 00:08:06,720 part we have actually seen that chicken 215 00:08:10,950 --> 00:08:09,360 eggs are able to develop 216 00:08:13,510 --> 00:08:10,960 when you launch them to space and 217 00:08:16,309 --> 00:08:13,520 incubate them and there's actually been 218 00:08:17,990 --> 00:08:16,319 some hatching of bird eggs 219 00:08:19,830 --> 00:08:18,000 on the mere space station which was the 220 00:08:22,150 --> 00:08:19,840 precursor to the international space 221 00:08:24,469 --> 00:08:22,160 station so we've had some success it 222 00:08:26,309 --> 00:08:24,479 hasn't been a perfect system 223 00:08:28,070 --> 00:08:26,319 the reason we ask questions like this 224 00:08:30,869 --> 00:08:28,080 and i assume this is why you're asking 225 00:08:33,750 --> 00:08:30,879 the question as well is it's un it's 226 00:08:37,190 --> 00:08:33,760 understanding is there a role of gravity 227 00:08:40,230 --> 00:08:37,200 in the development of an embryo 228 00:08:42,790 --> 00:08:40,240 and i think the jury is still out on on 229 00:08:43,990 --> 00:08:42,800 for sure knowing if gravity is important 230 00:08:45,670 --> 00:08:44,000 or not 231 00:08:47,670 --> 00:08:45,680 there's two schools of thoughts one of 232 00:08:48,550 --> 00:08:47,680 course is that gravity is 233 00:08:50,630 --> 00:08:48,560 um 234 00:08:52,630 --> 00:08:50,640 required and for you know early in 235 00:08:55,269 --> 00:08:52,640 gestation for development of like the 236 00:08:57,910 --> 00:08:55,279 neural tube of the organism 237 00:08:59,670 --> 00:08:57,920 but we've seen success without it so i 238 00:09:02,870 --> 00:08:59,680 think the jury's still out we've seen 239 00:09:05,350 --> 00:09:02,880 some success but it hasn't been perfect 240 00:09:06,710 --> 00:09:05,360 i think we still have a little bit to uh 241 00:09:09,430 --> 00:09:06,720 to understand maybe some more 242 00:09:14,389 --> 00:09:09,440 experiments to do 243 00:09:20,150 --> 00:09:16,790 um i was wondering what effect does 244 00:09:22,150 --> 00:09:20,160 micro gravity have on the human body 245 00:09:23,829 --> 00:09:22,160 well a little bit earlier i talked about 246 00:09:25,430 --> 00:09:23,839 um some of those effects and i'll go 247 00:09:27,110 --> 00:09:25,440 ahead and repeat them again because it's 248 00:09:29,509 --> 00:09:27,120 really what's very very interesting to 249 00:09:31,829 --> 00:09:29,519 me i am a physiologist and i'm 250 00:09:33,750 --> 00:09:31,839 interested in how the human body works 251 00:09:35,430 --> 00:09:33,760 which is fascinating itself but when you 252 00:09:37,590 --> 00:09:35,440 take the human body and you put it in an 253 00:09:40,710 --> 00:09:37,600 extreme environment like space or under 254 00:09:42,870 --> 00:09:40,720 the ocean those environmental changes 255 00:09:44,790 --> 00:09:42,880 cause a lot of cause a lot of problems 256 00:09:47,110 --> 00:09:44,800 for the human body in some cases but we 257 00:09:48,949 --> 00:09:47,120 are extremely adaptable it's one of the 258 00:09:50,550 --> 00:09:48,959 wonderful things about the human body we 259 00:09:52,790 --> 00:09:50,560 can live in a number 260 00:09:54,949 --> 00:09:52,800 of extreme environments and it's really 261 00:09:57,269 --> 00:09:54,959 fun to study what happens 262 00:09:59,430 --> 00:09:57,279 so when you go into space microgravity 263 00:10:01,750 --> 00:09:59,440 is one of the one of the largest 264 00:10:03,430 --> 00:10:01,760 environmental changes there's no gravity 265 00:10:05,430 --> 00:10:03,440 or no measurable gravity on the human 266 00:10:06,870 --> 00:10:05,440 body there's also radiation 267 00:10:09,430 --> 00:10:06,880 so the environment is pretty different 268 00:10:11,350 --> 00:10:09,440 than what we experience here on earth 269 00:10:13,590 --> 00:10:11,360 and the changes that the human body 270 00:10:16,150 --> 00:10:13,600 undergoes includes 271 00:10:19,750 --> 00:10:16,160 like i mentioned before some bone loss 272 00:10:21,590 --> 00:10:19,760 some muscle atrophy loss of muscle 273 00:10:23,430 --> 00:10:21,600 some cardiovascular deconditioning 274 00:10:25,110 --> 00:10:23,440 that's your heart and your lungs and 275 00:10:26,150 --> 00:10:25,120 your cardiovascular system getting 276 00:10:29,110 --> 00:10:26,160 weaker 277 00:10:30,790 --> 00:10:29,120 some immune system changes 278 00:10:32,550 --> 00:10:30,800 even some neurovestibular changes 279 00:10:34,790 --> 00:10:32,560 without normal gravity your inner ear 280 00:10:37,030 --> 00:10:34,800 gets a little bit confused usually that 281 00:10:38,550 --> 00:10:37,040 resolves itself pretty quickly but so 282 00:10:40,949 --> 00:10:38,560 there's a number of changes that the 283 00:10:43,030 --> 00:10:40,959 human body has to accommodate and adapt 284 00:10:45,670 --> 00:10:43,040 to but again because we're such an 285 00:10:48,310 --> 00:10:45,680 adaptable species within a couple days 286 00:10:50,230 --> 00:10:48,320 people get very used to living in space 287 00:10:52,310 --> 00:10:50,240 when they come back to earth 288 00:10:54,150 --> 00:10:52,320 they have to re-adapt to gravity as well 289 00:10:56,870 --> 00:10:54,160 but if if they've been 290 00:10:58,710 --> 00:10:56,880 exercising and eating right and and 291 00:11:00,230 --> 00:10:58,720 taking care of themselves that 292 00:11:02,310 --> 00:11:00,240 adaptation 293 00:11:03,509 --> 00:11:02,320 back to earth gravity isn't so bad and 294 00:11:05,269 --> 00:11:03,519 like i said we really want our 295 00:11:07,829 --> 00:11:05,279 astronauts to be healthy when they get 296 00:11:09,190 --> 00:11:07,839 back to earth or when we get to whatever 297 00:11:11,990 --> 00:11:09,200 terrestrial environment we're going to 298 00:11:14,069 --> 00:11:12,000 when we go to the moon or an asteroid or 299 00:11:15,590 --> 00:11:14,079 mars again we want our we want our 300 00:11:17,670 --> 00:11:15,600 astronauts to be healthy when they get 301 00:11:19,990 --> 00:11:17,680 to where they're going and so it's very 302 00:11:22,069 --> 00:11:20,000 important that they exercise eat right 303 00:11:23,990 --> 00:11:22,079 and take care of their bodies same thing 304 00:11:25,509 --> 00:11:24,000 for you and i eating and 305 00:11:27,990 --> 00:11:25,519 getting enough exercise is important for 306 00:11:29,030 --> 00:11:28,000 our our bodies as well it sounds like 307 00:11:30,630 --> 00:11:29,040 we're really starting to get a good 308 00:11:32,230 --> 00:11:30,640 handle on that right yeah i think you 309 00:11:33,910 --> 00:11:32,240 know we're really starting to get a good 310 00:11:35,670 --> 00:11:33,920 handle on it we're still learning a lot 311 00:11:38,870 --> 00:11:35,680 however um 312 00:11:40,550 --> 00:11:38,880 you may be aware that next march we 313 00:11:41,590 --> 00:11:40,560 are going to be launching two people 314 00:11:43,590 --> 00:11:41,600 that are going to live on the space 315 00:11:45,910 --> 00:11:43,600 station for an entire year a one year 316 00:11:47,829 --> 00:11:45,920 mission most of our experience is about 317 00:11:49,430 --> 00:11:47,839 six months the the people that are in 318 00:11:50,949 --> 00:11:49,440 space right now they're going to stay 319 00:11:52,550 --> 00:11:50,959 there for about six months on the 320 00:11:54,710 --> 00:11:52,560 international space station we've had a 321 00:11:55,910 --> 00:11:54,720 lot of experience many people have 322 00:11:58,389 --> 00:11:55,920 stayed on the international space 323 00:12:00,710 --> 00:11:58,399 station for six months we're going to 324 00:12:03,269 --> 00:12:00,720 learn some more when we go to one year 325 00:12:05,509 --> 00:12:03,279 it's twice as long so there's we're 326 00:12:07,509 --> 00:12:05,519 pretty excited to to do this and 327 00:12:09,190 --> 00:12:07,519 undertake this mission and learn about 328 00:12:11,670 --> 00:12:09,200 the changes in the human body that occur 329 00:12:13,590 --> 00:12:11,680 over a year and we we hope to learn a 330 00:12:15,350 --> 00:12:13,600 lot we also hope to find out that what 331 00:12:17,430 --> 00:12:15,360 we're doing for six months works for a 332 00:12:18,550 --> 00:12:17,440 year as well 333 00:12:20,389 --> 00:12:18,560 okay i think we're ready for the next 334 00:12:21,829 --> 00:12:20,399 question 335 00:12:24,150 --> 00:12:21,839 do you believe that there are planets 336 00:12:26,949 --> 00:12:24,160 similar to our past our galaxy and if so 337 00:12:29,590 --> 00:12:26,959 do you feel like there's intelligent on 338 00:12:31,910 --> 00:12:29,600 so nasa has a spacecraft it's a 339 00:12:33,910 --> 00:12:31,920 telescope called the kepler space 340 00:12:35,350 --> 00:12:33,920 telescope and its entire job is to 341 00:12:37,190 --> 00:12:35,360 search for 342 00:12:39,990 --> 00:12:37,200 planets that are maybe like earth 343 00:12:41,509 --> 00:12:40,000 outside of our galaxy and i think 344 00:12:44,550 --> 00:12:41,519 many have been found well over a 345 00:12:46,629 --> 00:12:44,560 thousand probably closer to 1500 346 00:12:50,069 --> 00:12:46,639 planets that are somewhat similar to 347 00:12:51,190 --> 00:12:50,079 earth in habitable zones near stars 348 00:12:53,430 --> 00:12:51,200 but 349 00:12:56,550 --> 00:12:53,440 do i believe intelligent life exists out 350 00:12:59,269 --> 00:12:56,560 there ah not really but i do believe 351 00:13:01,190 --> 00:12:59,279 that certainly even maybe in our solar 352 00:13:03,350 --> 00:13:01,200 our own solar system like on mars at 353 00:13:05,190 --> 00:13:03,360 some point may have supported some 354 00:13:07,670 --> 00:13:05,200 bacterial life or some kind of little 355 00:13:10,310 --> 00:13:07,680 cyanobacteria 356 00:13:12,310 --> 00:13:10,320 the conditions for life have to be 357 00:13:13,670 --> 00:13:12,320 pretty precise you have to 358 00:13:15,750 --> 00:13:13,680 as we know it you have to have some kind 359 00:13:17,110 --> 00:13:15,760 of water you have to have something for 360 00:13:18,629 --> 00:13:17,120 for the life to 361 00:13:20,870 --> 00:13:18,639 to consume and 362 00:13:23,190 --> 00:13:20,880 life has to produce waste and when you 363 00:13:25,829 --> 00:13:23,200 find water and you find moderate 364 00:13:27,990 --> 00:13:25,839 temperatures and you find minerals and 365 00:13:31,509 --> 00:13:28,000 resources i think there's a good chance 366 00:13:33,990 --> 00:13:31,519 that some type of life bacterial life 367 00:13:35,509 --> 00:13:34,000 could have existed or will exist and so 368 00:13:37,750 --> 00:13:35,519 i think i think it's only a matter of 369 00:13:39,350 --> 00:13:37,760 time before we find some other place in 370 00:13:40,389 --> 00:13:39,360 the universe 371 00:13:43,750 --> 00:13:40,399 where 372 00:13:46,389 --> 00:13:43,760 potentially life could be 373 00:13:48,389 --> 00:13:46,399 next question 374 00:13:50,150 --> 00:13:48,399 uh what type of training is required to 375 00:13:52,230 --> 00:13:50,160 be an astronaut and how long does it 376 00:13:53,509 --> 00:13:52,240 usually take 377 00:13:55,509 --> 00:13:53,519 brandy do you want to take that yeah i 378 00:13:57,030 --> 00:13:55,519 can take that one um so there's there's 379 00:14:00,069 --> 00:13:57,040 several different kind of layers i guess 380 00:14:02,790 --> 00:14:00,079 to that question uh first of all to even 381 00:14:06,389 --> 00:14:02,800 become an astronaut you have to have 382 00:14:09,110 --> 00:14:06,399 some experience in working in some um 383 00:14:11,110 --> 00:14:09,120 degrees and in math or science fields 384 00:14:12,710 --> 00:14:11,120 and really be pretty good at what you're 385 00:14:14,790 --> 00:14:12,720 already doing but then once you are 386 00:14:16,790 --> 00:14:14,800 selected to be an astronaut you've got a 387 00:14:17,990 --> 00:14:16,800 little ways to go from there you've got 388 00:14:19,670 --> 00:14:18,000 the initial training that all the 389 00:14:21,670 --> 00:14:19,680 astronauts go through that takes a 390 00:14:23,189 --> 00:14:21,680 couple of years um 391 00:14:25,509 --> 00:14:23,199 just getting them kind of caught up and 392 00:14:26,870 --> 00:14:25,519 up to speed on on what astronauts do and 393 00:14:28,629 --> 00:14:26,880 all the different kind of activities 394 00:14:30,230 --> 00:14:28,639 they might be called on and then once 395 00:14:32,310 --> 00:14:30,240 you actually get assigned to a mission 396 00:14:34,069 --> 00:14:32,320 you've got some more training to do so 397 00:14:35,990 --> 00:14:34,079 um you have to you have to learn a lot 398 00:14:38,790 --> 00:14:36,000 to be an astronaut it's not an easy job 399 00:14:40,150 --> 00:14:38,800 um but i think they would mostly 400 00:14:41,670 --> 00:14:40,160 probably all tell you that it's 401 00:14:43,110 --> 00:14:41,680 definitely worth the time that it takes 402 00:14:45,590 --> 00:14:43,120 they seem to have a lot of fun up in 403 00:14:47,110 --> 00:14:45,600 space so and there there are pilots who 404 00:14:49,030 --> 00:14:47,120 have become astronauts they're medical 405 00:14:51,910 --> 00:14:49,040 doctors who've become astronauts 406 00:14:53,030 --> 00:14:51,920 engineers um and lots of different types 407 00:14:55,990 --> 00:14:53,040 of scientists 408 00:14:57,590 --> 00:14:56,000 geologists and uh alex gerst an east 409 00:14:59,110 --> 00:14:57,600 astronaut in his face right now he's a 410 00:15:02,069 --> 00:14:59,120 volcanologist he's interested in 411 00:15:04,870 --> 00:15:02,079 volcanoes and so all kinds of different 412 00:15:06,629 --> 00:15:04,880 um backgrounds can be fields that 413 00:15:08,550 --> 00:15:06,639 contribute to the space program and 414 00:15:09,910 --> 00:15:08,560 being selected as an astronaut one of 415 00:15:12,230 --> 00:15:09,920 the things i've heard a lot of them say 416 00:15:13,670 --> 00:15:12,240 is pick a field that you really enjoy 417 00:15:15,750 --> 00:15:13,680 because if you enjoy what you're doing 418 00:15:17,030 --> 00:15:15,760 you'll be really good at it and being 419 00:15:18,710 --> 00:15:17,040 really good at all kind of raise you to 420 00:15:21,030 --> 00:15:18,720 the top of of your 421 00:15:22,470 --> 00:15:21,040 your class and and help you stand out 422 00:15:24,629 --> 00:15:22,480 when it comes time to actually apply to 423 00:15:26,230 --> 00:15:24,639 be an astronaut 424 00:15:28,069 --> 00:15:26,240 hope that answers your question uh next 425 00:15:30,310 --> 00:15:28,079 one 426 00:15:32,470 --> 00:15:30,320 hi i was wondering why time on earth was 427 00:15:34,710 --> 00:15:32,480 different from time and space 428 00:15:36,310 --> 00:15:34,720 okay that's a pretty complex question 429 00:15:39,350 --> 00:15:36,320 and i'm probably not the best person to 430 00:15:40,870 --> 00:15:39,360 answer it but i'll give it a shot um 431 00:15:43,910 --> 00:15:40,880 so the einstein 432 00:15:45,829 --> 00:15:43,920 uh in his theory of relative relativity 433 00:15:47,670 --> 00:15:45,839 stated that um 434 00:15:49,749 --> 00:15:47,680 gravity affects time 435 00:15:52,790 --> 00:15:49,759 and when you're close to a gravitational 436 00:15:53,990 --> 00:15:52,800 field time uh slows down a little bit so 437 00:15:56,710 --> 00:15:54,000 the further you are away from a 438 00:15:58,949 --> 00:15:56,720 gravitational field the faster time goes 439 00:16:01,749 --> 00:15:58,959 so we've actually measured this in 440 00:16:04,870 --> 00:16:01,759 spacecraft just in low earth orbit 441 00:16:07,910 --> 00:16:04,880 and so just a little bit away from earth 442 00:16:10,870 --> 00:16:07,920 there's just slightly less gravity and 443 00:16:12,550 --> 00:16:10,880 that actually affects time and so that 444 00:16:13,749 --> 00:16:12,560 somewhat answers your question and i 445 00:16:15,189 --> 00:16:13,759 know it's not perfect because i 446 00:16:17,670 --> 00:16:15,199 certainly don't have the best 447 00:16:20,230 --> 00:16:17,680 explanation but i will tell you that an 448 00:16:24,150 --> 00:16:20,240 astronaut living in space for six months 449 00:16:26,870 --> 00:16:24,160 will actually age .007 450 00:16:27,910 --> 00:16:26,880 seconds less than us here on earth and 451 00:16:29,110 --> 00:16:27,920 so 452 00:16:31,030 --> 00:16:29,120 i'll point out that one of the 453 00:16:33,110 --> 00:16:31,040 astronauts that is going to be living in 454 00:16:34,230 --> 00:16:33,120 space for one year on that one year 455 00:16:36,150 --> 00:16:34,240 mission 456 00:16:37,590 --> 00:16:36,160 he has a twin brother so scott kelly is 457 00:16:39,670 --> 00:16:37,600 the astronaut who will be living in 458 00:16:41,350 --> 00:16:39,680 space for a year he has a twin brother 459 00:16:44,150 --> 00:16:41,360 who's gonna stay here on earth his name 460 00:16:45,670 --> 00:16:44,160 is mark kelly and so they're twins so 461 00:16:47,670 --> 00:16:45,680 there's a slight age difference between 462 00:16:50,069 --> 00:16:47,680 them anyways just probably minutes i 463 00:16:52,550 --> 00:16:50,079 don't know exactly but when scott gets 464 00:16:54,550 --> 00:16:52,560 home he's going to be you know just a 465 00:16:57,670 --> 00:16:54,560 little bit younger 466 00:16:57,680 --> 00:17:03,030 all right next question 467 00:17:06,949 --> 00:17:05,189 we here on the news that mars and earth 468 00:17:08,870 --> 00:17:06,959 have similar environments even though 469 00:17:11,029 --> 00:17:08,880 there is no proof of life existing on 470 00:17:12,949 --> 00:17:11,039 mars today is there a possibility that 471 00:17:14,710 --> 00:17:12,959 humans might when they live there 472 00:17:16,150 --> 00:17:14,720 oh i sure hope so we're going to live on 473 00:17:17,750 --> 00:17:16,160 mars one day i think we're going to have 474 00:17:18,949 --> 00:17:17,760 a colony and there's people that are 475 00:17:20,710 --> 00:17:18,959 going to be staying there and living 476 00:17:23,189 --> 00:17:20,720 there it's a little ways off though 477 00:17:25,590 --> 00:17:23,199 because it's very challenging to do 478 00:17:27,669 --> 00:17:25,600 we're going to need to bring with us 479 00:17:29,830 --> 00:17:27,679 some pretty technologically advanced 480 00:17:31,350 --> 00:17:29,840 life support equipment 481 00:17:33,029 --> 00:17:31,360 we have some very technologically 482 00:17:35,110 --> 00:17:33,039 advanced life support equipment on the 483 00:17:37,190 --> 00:17:35,120 space station right now you can't live 484 00:17:39,510 --> 00:17:37,200 in space without bringing 485 00:17:41,510 --> 00:17:39,520 air and water in an environment and 486 00:17:43,029 --> 00:17:41,520 pressure and radiation protection you're 487 00:17:46,070 --> 00:17:43,039 going to need all of those things on 488 00:17:48,310 --> 00:17:46,080 mars too so mars is somewhat similar to 489 00:17:50,230 --> 00:17:48,320 earth and size and and the amount of 490 00:17:52,950 --> 00:17:50,240 sunlight it gets but there's more 491 00:17:54,150 --> 00:17:52,960 radiation more uv radiation it's really 492 00:17:57,669 --> 00:17:54,160 cold there 493 00:18:00,470 --> 00:17:57,679 the the atmosphere is very thin 494 00:18:02,470 --> 00:18:00,480 um and it's a lot of carbon dioxide we 495 00:18:04,950 --> 00:18:02,480 have mostly nitrogen in our atmosphere 496 00:18:06,710 --> 00:18:04,960 and they have mostly carbon dioxide and 497 00:18:08,870 --> 00:18:06,720 carbon dioxide is not really the most 498 00:18:10,950 --> 00:18:08,880 beneficial things for human to humans to 499 00:18:12,310 --> 00:18:10,960 breathe in high quantities 500 00:18:14,870 --> 00:18:12,320 so when we live on mars we're going to 501 00:18:17,750 --> 00:18:14,880 have to bring a lot of our own equipment 502 00:18:19,909 --> 00:18:17,760 um but that's part of the fun right it's 503 00:18:22,070 --> 00:18:19,919 part of the fun of exploration and 504 00:18:23,750 --> 00:18:22,080 and learning so yeah i think we're 505 00:18:24,950 --> 00:18:23,760 definitely gonna live on mars one day 506 00:18:28,070 --> 00:18:24,960 but we're just gonna have to bring a lot 507 00:18:29,350 --> 00:18:28,080 of uh a lot of comforts of home with us 508 00:18:30,950 --> 00:18:29,360 and you know we're we're building right 509 00:18:33,590 --> 00:18:30,960 now the spaceship that will take us 510 00:18:35,029 --> 00:18:33,600 there orion and it's getting ready um to 511 00:18:36,630 --> 00:18:35,039 go on its first test flight it won't go 512 00:18:38,870 --> 00:18:36,640 to mars the first time or even the 513 00:18:41,190 --> 00:18:38,880 second or third time um but we're gonna 514 00:18:43,270 --> 00:18:41,200 we're gonna send it 3 600 miles into 515 00:18:44,789 --> 00:18:43,280 space to test out a lot of its systems 516 00:18:46,310 --> 00:18:44,799 that we really want to make sure work 517 00:18:48,630 --> 00:18:46,320 before we put people on it and that test 518 00:18:50,549 --> 00:18:48,640 flight's coming up in december so 519 00:18:52,549 --> 00:18:50,559 we've just about got the spacecraft 520 00:18:54,230 --> 00:18:52,559 finished it's being built in florida at 521 00:18:56,390 --> 00:18:54,240 kennedy space center and it's supposed 522 00:18:57,909 --> 00:18:56,400 to launch on december 4th and we're also 523 00:19:00,470 --> 00:18:57,919 working on the rocket that would let us 524 00:19:04,470 --> 00:19:00,480 go to mars as well so that'll be 525 00:19:04,480 --> 00:19:09,510 next question 526 00:19:13,669 --> 00:19:12,070 hello and good morning my question for 527 00:19:15,669 --> 00:19:13,679 y'all is uh 528 00:19:17,750 --> 00:19:15,679 what changes do you see coming to 529 00:19:20,310 --> 00:19:17,760 research aboard the in-n-out space 530 00:19:21,510 --> 00:19:20,320 international space station 531 00:19:23,830 --> 00:19:21,520 so right now 532 00:19:26,150 --> 00:19:23,840 we've had about fifteen hundred and 533 00:19:28,549 --> 00:19:26,160 fifty different uh research 534 00:19:30,710 --> 00:19:28,559 investigations on the space station and 535 00:19:31,350 --> 00:19:30,720 uh come october we'll be counting you 536 00:19:33,029 --> 00:19:31,360 know 537 00:19:35,669 --> 00:19:33,039 your school as having one of those 538 00:19:37,669 --> 00:19:35,679 investigations so that's a lot and 539 00:19:39,590 --> 00:19:37,679 there's a lot coming and some of the 540 00:19:41,190 --> 00:19:39,600 changes that we see coming are we always 541 00:19:44,950 --> 00:19:41,200 have new facilities going to the space 542 00:19:46,950 --> 00:19:44,960 station that allow for new capabilities 543 00:19:48,390 --> 00:19:46,960 in fact one of those new capabilities is 544 00:19:50,549 --> 00:19:48,400 going to get there this fall where we're 545 00:19:52,390 --> 00:19:50,559 going to bring a 3d printer to the space 546 00:19:54,150 --> 00:19:52,400 station and that 547 00:19:56,310 --> 00:19:54,160 um we're actually doing research with it 548 00:19:57,909 --> 00:19:56,320 because we're not absolutely absolutely 549 00:19:58,870 --> 00:19:57,919 positive that it's going to work so 550 00:20:00,630 --> 00:19:58,880 we're going to bring it to the space 551 00:20:03,190 --> 00:20:00,640 station to test it out and once it's 552 00:20:05,430 --> 00:20:03,200 there um we're going to be able to 553 00:20:07,110 --> 00:20:05,440 perhaps build spare parts i know that 554 00:20:08,789 --> 00:20:07,120 that butch wilmore is pretty excited to 555 00:20:10,710 --> 00:20:08,799 get that 3d printer up there because 556 00:20:12,230 --> 00:20:10,720 he's a very handy guy he likes to build 557 00:20:14,149 --> 00:20:12,240 stuff and i think he's pretty excited to 558 00:20:16,789 --> 00:20:14,159 have that up there that's one example of 559 00:20:18,470 --> 00:20:16,799 a capability we also have a new habitat 560 00:20:20,070 --> 00:20:18,480 for fruit flies and we're going to be 561 00:20:23,430 --> 00:20:20,080 able to do a lot of genetics type of 562 00:20:25,110 --> 00:20:23,440 genomics experiments on them 563 00:20:27,110 --> 00:20:25,120 so we always have new equipment going to 564 00:20:28,870 --> 00:20:27,120 the space station new capabilities and 565 00:20:31,190 --> 00:20:28,880 new areas of research that we're looking 566 00:20:33,029 --> 00:20:31,200 forward to performing and that's that's 567 00:20:35,270 --> 00:20:33,039 just a quick highlight 568 00:20:38,549 --> 00:20:35,280 but if you go to our website which is 569 00:20:43,110 --> 00:20:41,110 iss hyphen science 570 00:20:44,870 --> 00:20:43,120 you can see there's we put out a lot of 571 00:20:46,390 --> 00:20:44,880 information there 572 00:20:48,070 --> 00:20:46,400 about the new facilities that are going 573 00:20:49,830 --> 00:20:48,080 to the space station the facilities that 574 00:20:51,669 --> 00:20:49,840 already exist there you know we have a 575 00:20:54,310 --> 00:20:51,679 centrifuge for spinning 576 00:20:56,630 --> 00:20:54,320 fluids down bodily fluids and otherwise 577 00:20:59,909 --> 00:20:56,640 we have some freezers really deep 578 00:21:02,149 --> 00:20:59,919 freezers minus 80 degrees celsius 579 00:21:04,470 --> 00:21:02,159 for storing samples 580 00:21:07,830 --> 00:21:04,480 we've got a combustion furnace for for 581 00:21:09,190 --> 00:21:07,840 doing combustion research we've got 582 00:21:12,149 --> 00:21:09,200 a fluids 583 00:21:14,070 --> 00:21:12,159 research rack for doing fluids research 584 00:21:15,430 --> 00:21:14,080 so we've got all types of equipment that 585 00:21:17,190 --> 00:21:15,440 is open for 586 00:21:19,510 --> 00:21:17,200 all kinds of scientists all over the 587 00:21:20,789 --> 00:21:19,520 world to propose their science and 588 00:21:22,390 --> 00:21:20,799 sometimes they have to have their own 589 00:21:23,830 --> 00:21:22,400 specialized equipment 590 00:21:27,190 --> 00:21:23,840 we have a lot of equipment mounted 591 00:21:28,310 --> 00:21:27,200 outside the space station as well 592 00:21:29,990 --> 00:21:28,320 so 593 00:21:31,430 --> 00:21:30,000 it's just more and more there's room for 594 00:21:32,630 --> 00:21:31,440 more science on the space station and 595 00:21:34,630 --> 00:21:32,640 that's something that we're interested 596 00:21:36,149 --> 00:21:34,640 in attracting and i'm glad that we're 597 00:21:37,830 --> 00:21:36,159 starting with students like yourselves 598 00:21:39,510 --> 00:21:37,840 we'd like we'd like for more people to 599 00:21:41,750 --> 00:21:39,520 propose experiments for the space 600 00:21:45,830 --> 00:21:41,760 station 601 00:21:49,830 --> 00:21:48,070 what kind of v-technology is being used 602 00:21:52,070 --> 00:21:49,840 to keep astronauts safe well in the 603 00:21:53,750 --> 00:21:52,080 international space station 604 00:21:56,149 --> 00:21:53,760 well um 605 00:21:57,990 --> 00:21:56,159 one type of new technology is is we're 606 00:21:59,669 --> 00:21:58,000 always trying to improve the amount and 607 00:22:01,029 --> 00:21:59,679 the types of exercise that the 608 00:22:03,110 --> 00:22:01,039 astronauts do 609 00:22:05,350 --> 00:22:03,120 we have three different devices up there 610 00:22:07,669 --> 00:22:05,360 we have a type of treadmill 611 00:22:09,669 --> 00:22:07,679 and we have a stationary bike 612 00:22:11,430 --> 00:22:09,679 and we have an advanced resistive 613 00:22:14,070 --> 00:22:11,440 exercise device which is kind of like a 614 00:22:15,990 --> 00:22:14,080 solo flex it's it's a it's like a 615 00:22:17,510 --> 00:22:16,000 modifiable gym equipment where you're 616 00:22:19,510 --> 00:22:17,520 not lifting weights but you're working 617 00:22:20,630 --> 00:22:19,520 against a resistive load 618 00:22:21,990 --> 00:22:20,640 and 619 00:22:23,750 --> 00:22:22,000 that's been up there for a little while 620 00:22:26,149 --> 00:22:23,760 but we're really kind of learning how 621 00:22:28,149 --> 00:22:26,159 best to use it by having really high 622 00:22:29,510 --> 00:22:28,159 intensity exercise and that's 623 00:22:33,190 --> 00:22:29,520 seeming to 624 00:22:35,029 --> 00:22:33,200 maintain astronaut bone very well 625 00:22:37,510 --> 00:22:35,039 and other technologies 626 00:22:39,190 --> 00:22:37,520 include better nutrition as well 627 00:22:40,950 --> 00:22:39,200 we've found that we have to reduce the 628 00:22:43,110 --> 00:22:40,960 amount of salt sodium intake that the 629 00:22:45,350 --> 00:22:43,120 astronauts are getting and that involves 630 00:22:47,350 --> 00:22:45,360 a whole team of food scientists here on 631 00:22:49,350 --> 00:22:47,360 the ground because the food has to taste 632 00:22:51,430 --> 00:22:49,360 good so it has to be palatable it has to 633 00:22:52,149 --> 00:22:51,440 have low salt but also has to have a 634 00:22:54,950 --> 00:22:52,159 good 635 00:22:56,789 --> 00:22:54,960 shelf life because once the food gets 636 00:22:58,630 --> 00:22:56,799 packaged and then launched to the space 637 00:23:00,710 --> 00:22:58,640 station we want it to be able to 638 00:23:02,310 --> 00:23:00,720 stay good and viable and all the 639 00:23:03,590 --> 00:23:02,320 nutrients are still available in the 640 00:23:04,870 --> 00:23:03,600 food for a while and so there's 641 00:23:06,789 --> 00:23:04,880 technologies that we're working on the 642 00:23:10,470 --> 00:23:06,799 ground as well to help 643 00:23:10,480 --> 00:23:15,510 okay next question 644 00:23:19,029 --> 00:23:16,549 what 645 00:23:23,110 --> 00:23:19,039 planets outside of this solar system 646 00:23:25,750 --> 00:23:23,120 would be able to sustain human life 647 00:23:28,070 --> 00:23:25,760 i don't think we have found any just yet 648 00:23:30,870 --> 00:23:28,080 but um i think we're you know we're 649 00:23:32,870 --> 00:23:30,880 searching we're looking um we've found 650 00:23:34,549 --> 00:23:32,880 planets that are similar in size to 651 00:23:37,350 --> 00:23:34,559 earth we've found planets that are 652 00:23:38,710 --> 00:23:37,360 similar in distance to a star 653 00:23:40,630 --> 00:23:38,720 as earth is 654 00:23:42,149 --> 00:23:40,640 so we're looking and you know i think 655 00:23:45,350 --> 00:23:42,159 one day we might find that we're not 656 00:23:47,029 --> 00:23:45,360 quite so unique there are there are 657 00:23:49,269 --> 00:23:47,039 billions and billions of stars and 658 00:23:51,430 --> 00:23:49,279 billions and billions of galaxies 659 00:23:53,909 --> 00:23:51,440 so i think you know the the longer we 660 00:23:57,909 --> 00:23:53,919 look the more we're going to find but uh 661 00:24:01,990 --> 00:23:59,990 and fayette academy this is nasa's 662 00:24:04,310 --> 00:24:02,000 digital learning network uh mike o'hare 663 00:24:05,750 --> 00:24:04,320 um just wanted to say that we're running 664 00:24:07,510 --> 00:24:05,760 out of time so i just wanted to see if 665 00:24:10,310 --> 00:24:07,520 you guys want to say any final words or 666 00:24:17,110 --> 00:24:10,320 thank you uh to dr warren and 667 00:24:21,029 --> 00:24:18,710 thank you sorry we didn't get a chance 668 00:24:23,029 --> 00:24:21,039 to get everybody's question but uh i'm 669 00:24:24,870 --> 00:24:23,039 sure glad you guys called today i'm glad 670 00:24:27,269 --> 00:24:24,880 we could answer some of your questions 671 00:24:28,870 --> 00:24:27,279 and uh good luck with your experiment 672 00:24:32,070 --> 00:24:28,880 i'm very excited to see it get up there 673 00:24:36,710 --> 00:24:32,080 i know butch is as well and stay curious
