00:01:24,560 taint middle school is it difficult to 19 00:01:35,590 --> 00:01:33,670 hi brianna good question i think for me 20 00:01:39,109 --> 00:01:35,600 the hardest part for me is leaving 21 00:01:41,590 --> 00:01:39,119 behind my family i'm married i have four 22 00:01:44,230 --> 00:01:41,600 kids and i have a granddaughter now too 23 00:01:45,670 --> 00:01:44,240 so it's hard for me to be away from home 24 00:01:47,749 --> 00:01:45,680 for a long time for those kind of 25 00:02:02,709 --> 00:01:47,759 reasons but i think what i'm doing here 26 00:02:02,719 --> 00:02:05,830 my name is lord 27 00:02:10,869 --> 00:02:06,830 my name 28 00:02:14,229 --> 00:02:10,879 is from hurting k28 middle school 29 00:02:22,150 --> 00:02:14,239 how long do you have to train 30 00:02:27,270 --> 00:02:24,390 hey louis it's a great question how long 31 00:02:29,270 --> 00:02:27,280 do you have to train for a mission uh 32 00:02:31,430 --> 00:02:29,280 the the training goes on for many years 33 00:02:34,630 --> 00:02:31,440 it really started when i was in school 34 00:02:38,150 --> 00:02:34,640 just like you as i began an interest in 35 00:02:41,190 --> 00:02:38,160 math and science and technology uh and 36 00:02:43,430 --> 00:02:41,200 and began actually laying the the basics 37 00:02:45,910 --> 00:02:43,440 or the foundations for my mission up 38 00:02:48,229 --> 00:02:45,920 here back when i was in grade school 39 00:02:50,309 --> 00:02:48,239 after you go through college and and 40 00:02:52,869 --> 00:02:50,319 work and are selected as an astronaut 41 00:02:55,589 --> 00:02:52,879 well then for a space station mission 42 00:02:57,910 --> 00:02:55,599 like this it was intensive training 43 00:02:59,589 --> 00:02:57,920 for two and a half years of dedicated 44 00:03:00,550 --> 00:02:59,599 training before i launched on this 45 00:03:03,110 --> 00:03:00,560 mission 46 00:03:05,110 --> 00:03:03,120 uh which is a a long time so you take 47 00:03:07,910 --> 00:03:05,120 two and a half years of training and 48 00:03:09,830 --> 00:03:07,920 then almost half a year in space so 49 00:03:11,990 --> 00:03:09,840 that's a that's a three year chunk out 50 00:03:13,509 --> 00:03:12,000 of your life and it is wonderful i'm 51 00:03:15,190 --> 00:03:13,519 enjoying every minute of it of the 52 00:03:25,589 --> 00:03:15,200 training and now every minute of the 53 00:03:29,270 --> 00:03:28,229 i'm takiyah vader from engineer k-8 54 00:03:31,350 --> 00:03:29,280 school 55 00:03:37,350 --> 00:03:31,360 how long does it take the space station 56 00:03:42,470 --> 00:03:39,270 that's a good really good question and 57 00:03:44,789 --> 00:03:42,480 it's kind of surprising it only takes us 58 00:03:46,869 --> 00:03:44,799 90 minutes to go all the way around the 59 00:03:48,309 --> 00:03:46,879 earth just an hour and a half 60 00:03:50,789 --> 00:03:48,319 because that's because we're going over 61 00:03:53,429 --> 00:03:50,799 17 000 miles an hour 62 00:03:55,429 --> 00:03:53,439 or about five miles a second and so it's 63 00:03:56,789 --> 00:03:55,439 it's really pretty amazing to look out 64 00:03:58,630 --> 00:03:56,799 the window and i've done this a few 65 00:04:02,149 --> 00:03:58,640 times when i had time on a weekend to 66 00:04:05,509 --> 00:04:02,159 just watch the world go by and to see 67 00:04:08,470 --> 00:04:05,519 an entire day in about 45 minutes and 68 00:04:10,869 --> 00:04:08,480 then night night time also about 45 69 00:04:13,110 --> 00:04:10,879 minutes so it's it's a it's pretty 70 00:04:14,789 --> 00:04:13,120 pretty cool to see that so knowing 71 00:04:16,229 --> 00:04:14,799 whether it's light outside doesn't 72 00:04:17,030 --> 00:04:16,239 doesn't make any difference to us 73 00:04:18,949 --> 00:04:17,040 because 74 00:04:20,710 --> 00:04:18,959 it doesn't get dark at night here when 75 00:04:22,790 --> 00:04:20,720 it's time for us to go to bed the sun is 76 00:04:24,390 --> 00:04:22,800 still shining bright and we're still 77 00:04:34,710 --> 00:04:24,400 going around the earth having a day and 78 00:04:39,189 --> 00:04:37,510 my name is santiago romero and 79 00:04:40,870 --> 00:04:39,199 i'm i'm an 8th grade student from 80 00:04:41,670 --> 00:04:40,880 wickerson middle school and my question 81 00:04:43,110 --> 00:04:41,680 is 82 00:04:45,510 --> 00:04:43,120 when are you on 83 00:04:47,430 --> 00:04:45,520 when when you are on the space station 84 00:04:49,670 --> 00:04:47,440 what prevents everyone and everything 85 00:04:53,909 --> 00:04:49,680 from bringing being sucked out into 86 00:04:59,030 --> 00:04:56,710 so tell that the answer to that is we 87 00:05:00,629 --> 00:04:59,040 don't open the windows uh we have 88 00:05:02,390 --> 00:05:00,639 windows these 89 00:05:04,390 --> 00:05:02,400 are our windows right behind me but 90 00:05:06,469 --> 00:05:04,400 there's no way to open those windows 91 00:05:08,950 --> 00:05:06,479 there's a cover on the outside and 92 00:05:10,550 --> 00:05:08,960 sometimes if you're listening to nasa tv 93 00:05:13,029 --> 00:05:10,560 we might talk about opening the windows 94 00:05:14,710 --> 00:05:13,039 but we're not really opening the windows 95 00:05:16,710 --> 00:05:14,720 we'll just there's a cover that helps 96 00:05:18,550 --> 00:05:16,720 protect the windows from being damaged 97 00:05:20,070 --> 00:05:18,560 by something or sometimes we want to 98 00:05:21,430 --> 00:05:20,080 keep the light 99 00:05:26,230 --> 00:05:21,440 from getting 100 00:05:28,950 --> 00:05:26,240 in and so the whole space station is 101 00:05:31,029 --> 00:05:28,960 sealed up and to keep all of the air 102 00:05:32,710 --> 00:05:31,039 inside and that's really really 103 00:05:34,310 --> 00:05:32,720 important and anytime we're doing 104 00:05:36,230 --> 00:05:34,320 something we do have little vents that 105 00:05:37,830 --> 00:05:36,240 go outside and we have hatches like when 106 00:05:40,230 --> 00:05:37,840 we do walks 107 00:05:42,230 --> 00:05:40,240 or have a hatch to the space shuttle or 108 00:05:44,790 --> 00:05:42,240 hatch to the soyuz spacecraft or one of 109 00:05:46,469 --> 00:05:44,800 our cargo ships and we'd spend a lot of 110 00:05:48,310 --> 00:05:46,479 time to make sure those are sealed 111 00:05:50,710 --> 00:05:48,320 perfectly so we're not going to leak air 112 00:05:53,189 --> 00:05:50,720 through those things now if the hole got 113 00:05:54,230 --> 00:05:53,199 punched in the wall right right behind 114 00:05:55,350 --> 00:05:54,240 here 115 00:05:58,790 --> 00:05:55,360 then 116 00:06:00,070 --> 00:05:58,800 rushing out of those holes and if it's a 117 00:06:02,390 --> 00:06:00,080 big enough hole then we're all going to 118 00:06:03,909 --> 00:06:02,400 get sucked out of it so we're but we 119 00:06:05,749 --> 00:06:03,919 it's all designed so we're not going to 120 00:06:08,070 --> 00:06:05,759 get holes in the wall it makes for an 121 00:06:10,390 --> 00:06:08,080 exciting scene in a movie 122 00:06:18,950 --> 00:06:10,400 but fortunately that kind of thing 123 00:06:22,390 --> 00:06:21,029 my name is elia torrell i'm from dane 124 00:06:25,110 --> 00:06:22,400 payne middle school 125 00:06:27,909 --> 00:06:25,120 what happens to rockin's when at rocket 126 00:06:33,510 --> 00:06:27,919 screen after they have finished with 127 00:06:36,710 --> 00:06:34,710 that's an interesting a really 128 00:06:37,990 --> 00:06:36,720 interesting question what happens to 129 00:06:41,270 --> 00:06:38,000 rockets when they're finished with their 130 00:06:43,029 --> 00:06:41,280 mission uh it it it depends but in 131 00:06:44,710 --> 00:06:43,039 general the rocket 132 00:06:46,790 --> 00:06:44,720 is you could think of it as being made 133 00:06:48,550 --> 00:06:46,800 up of a few different pieces and the 134 00:06:50,870 --> 00:06:48,560 first part is the rocket with all the 135 00:06:53,830 --> 00:06:50,880 fuels and the big rocket engine to get 136 00:06:55,830 --> 00:06:53,840 us off the ground and up into space and 137 00:06:57,990 --> 00:06:55,840 those typically 138 00:07:00,070 --> 00:06:58,000 come in separate sections too and when 139 00:07:03,029 --> 00:07:00,080 they burn out when they use up the fuel 140 00:07:05,350 --> 00:07:03,039 in those sections those things fall away 141 00:07:06,950 --> 00:07:05,360 now the space shuttle kept its engines 142 00:07:08,150 --> 00:07:06,960 and brought those engines back to the 143 00:07:09,909 --> 00:07:08,160 ground 144 00:07:11,749 --> 00:07:09,919 uh to reuse again 145 00:07:13,909 --> 00:07:11,759 and it just the big orange fuel tank 146 00:07:17,029 --> 00:07:13,919 fell away and was actually burned up as 147 00:07:18,790 --> 00:07:17,039 it fell back into the atmosphere 148 00:07:20,550 --> 00:07:18,800 with the other rockets like the soyuz 149 00:07:23,589 --> 00:07:20,560 rocket that i came up on it has some 150 00:07:25,189 --> 00:07:23,599 stages or some some kind of like rockets 151 00:07:26,790 --> 00:07:25,199 stacked on top of each other and the 152 00:07:28,950 --> 00:07:26,800 first ones you burn are the really big 153 00:07:30,629 --> 00:07:28,960 ones at the bottom and those fall away 154 00:07:33,029 --> 00:07:30,639 and the next one lights and it keeps 155 00:07:34,309 --> 00:07:33,039 pushing you up further and further 156 00:07:36,230 --> 00:07:34,319 and but 157 00:07:38,710 --> 00:07:36,240 the short answer is 158 00:07:40,710 --> 00:07:38,720 that today there's very little of 159 00:07:42,710 --> 00:07:40,720 rockets that are re 160 00:07:45,189 --> 00:07:42,720 very little that's reused you've got 161 00:07:46,869 --> 00:07:45,199 the again the rocket part that pushes us 162 00:07:50,070 --> 00:07:46,879 up and then there's the part that we're 163 00:07:52,550 --> 00:07:50,080 in the spaceship part of the rocket that 164 00:07:54,710 --> 00:07:52,560 has the humans you know on the top 165 00:07:56,550 --> 00:07:54,720 and that of course 166 00:07:59,589 --> 00:07:56,560 makes it all the way to orbit is 167 00:08:01,430 --> 00:07:59,599 attached to the space station right now 168 00:08:03,430 --> 00:08:01,440 and then when we go home 169 00:08:05,510 --> 00:08:03,440 that protects us from the 170 00:08:07,830 --> 00:08:05,520 incredibly hot temperatures as we're 171 00:08:11,110 --> 00:08:07,840 re-entering the atmosphere to come home 172 00:08:14,150 --> 00:08:11,120 to earth and a few pieces of that 173 00:08:30,070 --> 00:08:14,160 spaceship get reused but most of it goes 174 00:08:30,080 --> 00:08:33,990 got it 175 00:08:37,269 --> 00:08:35,909 my name is jamir and i'm from hudson 176 00:08:39,110 --> 00:08:37,279 k-38 177 00:08:44,870 --> 00:08:39,120 if i want to be an astronaut what should 178 00:08:49,910 --> 00:08:47,190 well that's a great question because the 179 00:08:51,910 --> 00:08:49,920 the answer to that is depends a lot on 180 00:08:53,910 --> 00:08:51,920 what you really love what are you 181 00:08:57,269 --> 00:08:53,920 interested in i mean everybody that's an 182 00:08:57,990 --> 00:08:57,279 astronaut has a background in education 183 00:09:03,990 --> 00:08:58,000 in 184 00:09:05,190 --> 00:09:04,000 mathematics and that covers a lot of 185 00:09:07,350 --> 00:09:05,200 different areas and when we have 186 00:09:09,190 --> 00:09:07,360 astronauts that are geologists they 187 00:09:10,230 --> 00:09:09,200 really like rocks 188 00:09:13,269 --> 00:09:10,240 chemists 189 00:09:16,070 --> 00:09:13,279 physicists medical doctors engineers of 190 00:09:17,550 --> 00:09:16,080 any kind i'm a mechanical engineer we 191 00:09:20,470 --> 00:09:17,560 have you know 192 00:09:22,550 --> 00:09:20,480 astronautical engineers we have mechanic 193 00:09:25,269 --> 00:09:22,560 or electrical engineers lots of 194 00:09:27,030 --> 00:09:25,279 different kind of engineers too and so 195 00:09:29,110 --> 00:09:27,040 the real answer for what you should 196 00:09:29,829 --> 00:09:29,120 study if you want my job 197 00:09:31,269 --> 00:09:29,839 is 198 00:09:33,110 --> 00:09:31,279 it depends on what you're really 199 00:09:36,150 --> 00:09:33,120 interested in because you have to be 200 00:09:37,750 --> 00:09:36,160 interested in it in order to stick to it 201 00:09:39,190 --> 00:09:37,760 and to be one of the best and that's 202 00:09:40,470 --> 00:09:39,200 what you really want to do is do 203 00:09:41,269 --> 00:09:40,480 something you love 204 00:09:43,509 --> 00:09:41,279 and 205 00:09:46,070 --> 00:09:43,519 work at it really hard so you can be one 206 00:09:48,790 --> 00:09:46,080 of the best people ever doing whatever 207 00:09:51,030 --> 00:09:48,800 it is that you love doing and that's how 208 00:10:01,190 --> 00:09:51,040 you have your best chance of taking my 209 00:10:06,389 --> 00:10:03,750 my name is maya wilson from casey ray 210 00:10:11,910 --> 00:10:06,399 school how long have you spent space and 211 00:10:16,550 --> 00:10:14,310 oh that's that's a great question milo 212 00:10:19,110 --> 00:10:16,560 i've been up here this time four and a 213 00:10:21,269 --> 00:10:19,120 half months in space 214 00:10:23,590 --> 00:10:21,279 which is uh that's a long time for me i 215 00:10:26,470 --> 00:10:23,600 flow twice on the space shuttle and for 216 00:10:28,870 --> 00:10:26,480 those missions that was just two weeks 217 00:10:31,750 --> 00:10:28,880 and i thought those were long and really 218 00:10:33,750 --> 00:10:31,760 busy and now this is really long to be 219 00:10:35,430 --> 00:10:33,760 up here five and a half months 220 00:10:37,269 --> 00:10:35,440 we've had people on the space station 221 00:10:39,750 --> 00:10:37,279 longer the russians have had people 222 00:10:41,990 --> 00:10:39,760 living in space for over a year and so 223 00:10:43,990 --> 00:10:42,000 you could theoretically you could stay 224 00:10:47,350 --> 00:10:44,000 longer than five and a half or six 225 00:10:48,150 --> 00:10:47,360 months which is what we're planning for 226 00:10:50,310 --> 00:10:48,160 but 227 00:10:53,030 --> 00:10:50,320 normally we don't do that because living 228 00:10:54,750 --> 00:10:53,040 in space is kind of hard on the body 229 00:10:56,949 --> 00:10:54,760 it's hard on your bones in your 230 00:10:58,150 --> 00:10:56,959 cardiovascular system your heart and 231 00:11:00,069 --> 00:10:58,160 lungs 232 00:11:02,069 --> 00:11:00,079 to to be up here where it gets kind of 233 00:11:05,269 --> 00:11:02,079 lazy because my bones don't have to 234 00:11:07,590 --> 00:11:05,279 support my body i'm just floating around 235 00:11:11,269 --> 00:11:07,600 and so when i'm just floating around my 236 00:11:14,389 --> 00:11:12,550 maybe 237 00:11:17,750 --> 00:11:14,399 floating around out of control 238 00:11:20,069 --> 00:11:17,760 uh and so it's a and the muscles don't 239 00:11:22,550 --> 00:11:20,079 have to do as much work up here because 240 00:11:24,710 --> 00:11:22,560 nothing weighs anything it has mass but 241 00:11:26,710 --> 00:11:24,720 it doesn't have weight and so i can move 242 00:11:29,750 --> 00:11:26,720 things around that weigh a thousand 243 00:11:32,230 --> 00:11:29,760 pounds as long as i move slowly it's 244 00:11:34,790 --> 00:11:32,240 okay so it's hard on the body to be up 245 00:11:44,150 --> 00:11:34,800 here for for a long time so we limit it 246 00:11:49,190 --> 00:11:46,550 my name is jayla glenn and i'm from 247 00:11:58,710 --> 00:11:49,200 hudson k2a school how often do you get 248 00:12:03,509 --> 00:12:00,629 almost every day 249 00:12:06,470 --> 00:12:03,519 we we have different ways to do that uh 250 00:12:09,670 --> 00:12:06,480 every weekend i get a a video conference 251 00:12:12,550 --> 00:12:09,680 just 15 minutes and sometimes longer uh 252 00:12:13,350 --> 00:12:12,560 with my wife and and one son that's at 253 00:12:15,910 --> 00:12:13,360 home 254 00:12:18,629 --> 00:12:15,920 uh and the other kids if they're there 255 00:12:21,269 --> 00:12:18,639 i we also have a telephone it's not a 256 00:12:22,870 --> 00:12:21,279 normal telephone like you have but it's 257 00:12:25,190 --> 00:12:22,880 through the computers and stuff where i 258 00:12:26,949 --> 00:12:25,200 can actually call people and so i call 259 00:12:28,629 --> 00:12:26,959 my my family 260 00:12:31,030 --> 00:12:28,639 almost every day i have the chance to 261 00:12:33,350 --> 00:12:31,040 call my family and say hi and talk about 262 00:12:35,590 --> 00:12:33,360 school and work and how things are going 263 00:12:37,350 --> 00:12:35,600 so that's one way that we keep in touch 264 00:12:39,430 --> 00:12:37,360 we also have email 265 00:12:41,590 --> 00:12:39,440 and so it's not as fast as email you 266 00:12:43,350 --> 00:12:41,600 can't trade emails i can't send one and 267 00:12:45,350 --> 00:12:43,360 you can't receive it and answer me right 268 00:12:47,509 --> 00:12:45,360 back and and then i get it we have a 269 00:12:50,389 --> 00:12:47,519 conversation like that it doesn't work 270 00:12:52,150 --> 00:12:50,399 that well but it it is a way of staying 271 00:13:00,629 --> 00:12:52,160 in touch with family and friends which 272 00:13:05,269 --> 00:13:03,110 my name is ray shaw taylor from carver 273 00:13:07,110 --> 00:13:05,279 high school and my question is have you 274 00:13:18,629 --> 00:13:07,120 ever encountered anything unusual while 275 00:13:22,790 --> 00:13:20,389 would make for a good scene in the movie 276 00:13:25,190 --> 00:13:22,800 i haven't seen anything like that uh 277 00:13:28,389 --> 00:13:25,200 i've seen unusual things though i i've 278 00:13:30,790 --> 00:13:28,399 seen the aurora borealis and australis 279 00:13:33,269 --> 00:13:30,800 the the northern and southern lights are 280 00:13:35,670 --> 00:13:33,279 starting to become more active now and 281 00:13:37,750 --> 00:13:35,680 that's a fascinating thing to see with 282 00:13:39,030 --> 00:13:37,760 your eyes up here where you're not on 283 00:13:40,949 --> 00:13:39,040 the ground you can see them in the 284 00:13:43,110 --> 00:13:40,959 northern parts of the united states you 285 00:13:45,430 --> 00:13:43,120 can see it sometimes 286 00:13:47,110 --> 00:13:45,440 or in the southern parts of the world 287 00:13:49,189 --> 00:13:47,120 but up here you have the chance to fly 288 00:13:51,030 --> 00:13:49,199 through those areas and 289 00:13:53,189 --> 00:13:51,040 and you can actually we actually fly 290 00:13:55,829 --> 00:13:53,199 through it and it's it's a pretty 291 00:13:57,829 --> 00:13:55,839 strange thing with this incredible green 292 00:13:58,710 --> 00:13:57,839 kind of waving lights and there's some 293 00:14:00,949 --> 00:13:58,720 red 294 00:14:02,550 --> 00:14:00,959 glowing in the atmosphere up above too 295 00:14:05,910 --> 00:14:02,560 which is really cool 296 00:14:07,189 --> 00:14:05,920 uh i think other than that the 297 00:14:09,430 --> 00:14:07,199 you know that's probably the coolest 298 00:14:20,470 --> 00:14:09,440 thing of all of this really cool 299 00:14:24,470 --> 00:14:22,389 my name is kiera victor and i attend 300 00:14:29,670 --> 00:14:24,480 carver high school i want to know why do 301 00:14:34,389 --> 00:14:31,829 hey carrick good question we wear 302 00:14:36,150 --> 00:14:34,399 spacesuits for the same reason uh when 303 00:14:37,910 --> 00:14:36,160 we're talking about why 304 00:14:39,990 --> 00:14:37,920 we don't you know because there's a 305 00:14:42,870 --> 00:14:40,000 vacuum outside there's no air outside we 306 00:14:44,629 --> 00:14:42,880 don't all get sucked outside and die 307 00:14:46,629 --> 00:14:44,639 the spacesuit we wear for the same 308 00:14:47,350 --> 00:14:46,639 reason to keep that air pressure around 309 00:14:50,550 --> 00:14:47,360 us 310 00:14:52,389 --> 00:14:50,560 our air pressure up here 311 00:14:54,310 --> 00:14:52,399 where we're living and working in space 312 00:14:56,949 --> 00:14:54,320 is the same as the air pressure around 313 00:14:58,710 --> 00:14:56,959 you right now in alabama and and we keep 314 00:15:01,110 --> 00:14:58,720 it that way because that's what where 315 00:15:02,470 --> 00:15:01,120 our bodies were designed to work at this 316 00:15:04,550 --> 00:15:02,480 kind of pressure and live at this 317 00:15:07,110 --> 00:15:04,560 pressure the spacesuit is designed to 318 00:15:09,910 --> 00:15:07,120 keep the air pressure around our bodies 319 00:15:12,389 --> 00:15:09,920 to to uh to help keep us healthy it also 320 00:15:13,910 --> 00:15:12,399 protects us from extreme cold 321 00:15:16,470 --> 00:15:13,920 or heat 322 00:15:18,910 --> 00:15:16,480 i've done seven space walks and outside 323 00:15:20,870 --> 00:15:18,920 the temperatures can get plus and minus 324 00:15:22,870 --> 00:15:20,880 200 degrees 325 00:15:24,949 --> 00:15:22,880 if it if it's away from the sun it gets 326 00:15:27,110 --> 00:15:24,959 really really cold and if the sun's 327 00:15:30,470 --> 00:15:27,120 shining on things it can get 200 degrees 328 00:15:32,949 --> 00:15:30,480 or even hotter from the intense energy 329 00:15:46,470 --> 00:15:32,959 on it so it the spacesuit protects us 330 00:15:50,069 --> 00:15:48,389 my name is marvel rhodes and i attend 331 00:15:52,069 --> 00:15:50,079 george washington high school my 332 00:15:54,710 --> 00:15:52,079 question is why do the rockets get i 333 00:16:00,389 --> 00:15:54,720 mean excuse me how do the rockets get to 334 00:16:04,550 --> 00:16:01,350 it's a 335 00:16:05,670 --> 00:16:04,560 good question margo the the rockets use 336 00:16:08,230 --> 00:16:05,680 thrust 337 00:16:09,829 --> 00:16:08,240 and they generate a lot of energy you 338 00:16:12,710 --> 00:16:09,839 know pushing out of the back of the 339 00:16:16,069 --> 00:16:12,720 rocket and it we combine a fuel 340 00:16:17,590 --> 00:16:16,079 and an oxidizer and a 341 00:16:21,030 --> 00:16:17,600 simple way to think of it would be like 342 00:16:23,910 --> 00:16:21,040 gasoline and oxygen it's not gasoline 343 00:16:25,829 --> 00:16:23,920 but you know it's fuels that that that 344 00:16:27,430 --> 00:16:25,839 we're all familiar with and you combine 345 00:16:30,470 --> 00:16:27,440 the two of them together it makes an 346 00:16:33,350 --> 00:16:30,480 explosive mixture that burns really 347 00:16:35,189 --> 00:16:33,360 really well and very very quickly uh and 348 00:16:37,509 --> 00:16:35,199 you know if you have some some gasoline 349 00:16:39,030 --> 00:16:37,519 or alcohol that that's out 350 00:16:41,110 --> 00:16:39,040 uh you know and you light it and i'm not 351 00:16:43,189 --> 00:16:41,120 recommending that uh you know you'll see 352 00:16:45,350 --> 00:16:43,199 that it burns and kind of a it mixes 353 00:16:47,430 --> 00:16:45,360 with air and stuff when when you mix the 354 00:16:50,550 --> 00:16:47,440 oxygen with it in that rocket engine it 355 00:16:54,790 --> 00:16:50,560 creates uh i mean a tremendous reaction 356 00:16:58,069 --> 00:16:54,800 of of force as the those liquids are 357 00:17:00,470 --> 00:16:58,079 expanding then into hot gas and the 358 00:17:03,189 --> 00:17:00,480 nozzle of the rocket kind of funnels 359 00:17:05,510 --> 00:17:03,199 that and push and directs it to push it 360 00:17:07,029 --> 00:17:05,520 down and you're sitting up on top of it 361 00:17:08,630 --> 00:17:07,039 and so that it's that's the kind of 362 00:17:09,909 --> 00:17:08,640 force that's generated from that 363 00:17:12,549 --> 00:17:09,919 combustion 364 00:17:13,990 --> 00:17:12,559 of the oxidizer and the fuel 365 00:17:17,750 --> 00:17:14,000 and then going through the nozzle of the 366 00:17:19,909 --> 00:17:17,760 rocket to push and it's literally a push 367 00:17:22,710 --> 00:17:19,919 i don't know the numbers for the soyuz 368 00:17:24,710 --> 00:17:22,720 rocket for the space shuttle it it 369 00:17:26,710 --> 00:17:24,720 weighs about four and a half million 370 00:17:29,270 --> 00:17:26,720 pounds sitting on the ground 371 00:17:32,230 --> 00:17:29,280 uh that's the the space shuttle itself 372 00:17:34,310 --> 00:17:32,240 and the fuel tanks and everything else 373 00:17:37,029 --> 00:17:34,320 and when it's leaving the earth it's 374 00:17:38,070 --> 00:17:37,039 pushing with over 7 million pounds of 375 00:17:40,070 --> 00:17:38,080 thrust 376 00:17:42,950 --> 00:17:40,080 and so that's that's a tremendous amount 377 00:17:43,830 --> 00:17:42,960 of incredible energies involved to get 378 00:17:45,830 --> 00:17:43,840 us 379 00:17:46,630 --> 00:17:45,840 from sitting still on the surface of the 380 00:17:49,430 --> 00:17:46,640 earth 381 00:17:51,669 --> 00:17:49,440 and into orbit around the planet 382 00:17:53,990 --> 00:17:51,679 in about nine minutes 383 00:18:05,110 --> 00:17:54,000 it's a it's huge energies involved it's 384 00:18:09,510 --> 00:18:07,510 my name is demarcus jimbo and i attend 385 00:18:11,669 --> 00:18:09,520 dave payne middle school 386 00:18:14,070 --> 00:18:11,679 why are things different in space for 387 00:18:19,350 --> 00:18:14,080 example why do footprints stay on the 388 00:18:24,870 --> 00:18:22,470 oh that's a great question uh marcus the 389 00:18:26,789 --> 00:18:24,880 the the with for the moon 390 00:18:28,710 --> 00:18:26,799 i mean what changes the earth all the 391 00:18:30,390 --> 00:18:28,720 time if you go out and put footprints in 392 00:18:33,590 --> 00:18:30,400 the mud today 393 00:18:35,430 --> 00:18:33,600 sometime in the next week or two so the 394 00:18:37,190 --> 00:18:35,440 wind's going to come along somebody else 395 00:18:39,029 --> 00:18:37,200 is going to come along and step on them 396 00:18:40,950 --> 00:18:39,039 or a car is going to drive over them or 397 00:18:43,669 --> 00:18:40,960 it's going to rain again and it's going 398 00:18:45,190 --> 00:18:43,679 to wash it away the moon doesn't have 399 00:18:47,110 --> 00:18:45,200 the kind of weather that we have here 400 00:18:48,630 --> 00:18:47,120 because the weather depends on 401 00:18:51,110 --> 00:18:48,640 an atmosphere 402 00:18:53,830 --> 00:18:51,120 and rain and wind 403 00:18:55,510 --> 00:18:53,840 erosion processes and things like that 404 00:18:57,430 --> 00:18:55,520 that's why the moon has all these 405 00:18:59,510 --> 00:18:57,440 craters if you look at the moon with a 406 00:19:01,909 --> 00:18:59,520 good set of binoculars you can see these 407 00:19:03,750 --> 00:19:01,919 craters pockmarking the moon it's really 408 00:19:06,310 --> 00:19:03,760 amazing 409 00:19:08,230 --> 00:19:06,320 but the earth is in the same space that 410 00:19:09,750 --> 00:19:08,240 the moon is in so when we look at the 411 00:19:11,909 --> 00:19:09,760 earth and i look at the earth and i'm 412 00:19:14,549 --> 00:19:11,919 looking for these craters and you can 413 00:19:16,870 --> 00:19:14,559 find some there's there are many craters 414 00:19:18,789 --> 00:19:16,880 on the earth but they're barely visible 415 00:19:21,750 --> 00:19:18,799 most of them are just barely visible 416 00:19:24,390 --> 00:19:21,760 anymore because over time 417 00:19:26,950 --> 00:19:24,400 the weather processes have kind of 418 00:19:29,510 --> 00:19:26,960 washed away or eroded away 419 00:19:31,350 --> 00:19:29,520 most of the big signs of these craters 420 00:19:32,710 --> 00:19:31,360 as well as on the earth we have plate 421 00:19:34,950 --> 00:19:32,720 tectonics and that gets really 422 00:19:37,510 --> 00:19:34,960 complicated where the plates that make 423 00:19:39,430 --> 00:19:37,520 up the surface of our earth are shifting 424 00:19:42,070 --> 00:19:39,440 and grinding against each other over 425 00:19:43,590 --> 00:19:42,080 time and uh you know so there's several 426 00:19:45,510 --> 00:19:43,600 things but those footprints they leave 427 00:19:46,630 --> 00:19:45,520 on the moon are going to be there for a 428 00:19:48,710 --> 00:19:46,640 long time 429 00:19:50,070 --> 00:19:48,720 and i think it's really kind of cool to 430 00:19:52,789 --> 00:19:50,080 think about the fact that there are 431 00:19:54,310 --> 00:19:52,799 still you know our human footprints on 432 00:19:55,830 --> 00:19:54,320 the moon and someday we're going to go 433 00:19:58,150 --> 00:19:55,840 back up there and we're going to see 434 00:20:01,190 --> 00:19:58,160 that the footprints and the tire tracks 435 00:20:02,549 --> 00:20:01,200 from the lunar rovers and someday 436 00:20:04,470 --> 00:20:02,559 we're going to be putting human 437 00:20:06,390 --> 00:20:04,480 footprints on mars 438 00:20:07,830 --> 00:20:06,400 and that's a really cool thing too but 439 00:20:09,990 --> 00:20:07,840 they're not going to stay on mars 440 00:20:11,350 --> 00:20:10,000 because mars has wind 441 00:20:13,510 --> 00:20:11,360 it doesn't have much atmosphere it's 442 00:20:15,190 --> 00:20:13,520 very thin but it does have wind that 443 00:20:17,350 --> 00:20:15,200 kicks up big dust storms so the 444 00:20:19,110 --> 00:20:17,360 footprints on mars will make the history 445 00:20:24,950 --> 00:20:19,120 books but they won't be there a hundred 446 00:20:29,110 --> 00:20:27,430 commander felson thank you so much we 447 00:20:31,110 --> 00:20:29,120 are just so thrilled to have this 448 00:20:33,270 --> 00:20:31,120 opportunity and i know i speak on behalf 449 00:20:35,510 --> 00:20:33,280 of all those students here and 450 00:20:37,510 --> 00:20:35,520 birmingham and bessemer city schools and 451 00:20:39,430 --> 00:20:37,520 americans to say thank you for your 452 00:20:52,149 --> 00:20:39,440 service thank you so much for this 453 00:20:55,510 --> 00:20:53,750 safe travels 454 00:20:58,470 --> 00:20:55,520 oh 455 00:21:00,710 --> 00:20:58,480 thank you very much the the the children 456 00:21:02,870 --> 00:21:00,720 are amazing those were some awesome 457 00:21:04,870 --> 00:21:02,880 questions some really good questions i 458 00:21:06,710 --> 00:21:04,880 can tell they're really thinking and i 459 00:21:08,630 --> 00:21:06,720 know that the the purpose of this is to 460 00:21:10,470 --> 00:21:08,640 expose them to different ideas about the 461 00:21:13,430 --> 00:21:10,480 science and technology engineering and 462 00:21:14,789 --> 00:21:13,440 math that are key to our future there's 463 00:21:15,750 --> 00:21:14,799 a lot of things that they hear about in 464 00:21:16,789 --> 00:21:15,760 the world 465 00:21:18,470 --> 00:21:16,799 then and 466 00:21:19,669 --> 00:21:18,480 the key to figuring out some of these 467 00:21:21,750 --> 00:21:19,679 problems that they hear about in the 468 00:21:23,430 --> 00:21:21,760 news are really 469 00:21:25,350 --> 00:21:23,440 delving into the science and the 470 00:21:26,950 --> 00:21:25,360 technology behind these things to find 471 00:21:29,590 --> 00:21:26,960 out better solutions for a better 472 00:21:31,270 --> 00:21:29,600 tomorrow and enjoy the 473 00:21:33,270 --> 00:21:31,280 enjoy the adventures because it is fun 474 00:21:35,510 --> 00:21:33,280 stuff it's exciting stuff i've really 475 00:21:37,190 --> 00:21:35,520 enjoyed talking to you and 476 00:21:40,870 --> 00:21:37,200 now it's mike fossum on the 477 00:21:46,230 --> 00:21:43,430 station this is houston acr thank you 478 00:21:47,830 --> 00:21:46,240 that concludes the event 479 00:21:49,830 --> 00:21:47,840 and thank you carver high school 480 00:21:51,270 --> 00:21:49,840 representative
