event 4 00:00:15,990 --> 00:00:14,480 senator nelson this is mission control 5 00:00:19,750 --> 00:00:16,000 houston please call the station for a 6 00:00:26,950 --> 00:00:22,950 this is bill nelson i'm in the senate 7 00:00:33,750 --> 00:00:29,910 senator nelson i read you loud and clear 8 00:00:37,270 --> 00:00:35,510 dr marshburn 9 00:00:41,750 --> 00:00:37,280 you are 10 00:00:44,630 --> 00:00:41,760 one who joined nasa in 1994 11 00:00:46,869 --> 00:00:44,640 as a flight surgeon 12 00:00:48,069 --> 00:00:46,879 and ten years later you were selected to 13 00:00:51,430 --> 00:00:48,079 become 14 00:00:55,750 --> 00:00:51,440 a member of the astronaut office 15 00:00:57,510 --> 00:00:55,760 your sp first space flight came in 09 16 00:00:59,750 --> 00:00:57,520 aboard endeavour 17 00:01:01,750 --> 00:00:59,760 and now you're on your second trip to 18 00:01:03,590 --> 00:01:01,760 space 19 00:01:06,310 --> 00:01:03,600 you've spent the last four and a half 20 00:01:09,670 --> 00:01:06,320 months orbiting the earth 21 00:01:11,510 --> 00:01:09,680 on the station uh what is your specific 22 00:01:16,390 --> 00:01:11,520 location right now 23 00:01:20,230 --> 00:01:18,310 well senator right now i'm at the 24 00:01:22,630 --> 00:01:20,240 forward end of the space station i'm the 25 00:01:24,630 --> 00:01:22,640 japanese experiment module so our 26 00:01:27,109 --> 00:01:24,640 velocity vector is that way we're flying 27 00:01:28,870 --> 00:01:27,119 that way all around me and behind me is 28 00:01:30,630 --> 00:01:28,880 the vacuum of space behind me is 29 00:01:32,390 --> 00:01:30,640 actually an external platform that's 30 00:01:35,030 --> 00:01:32,400 encrusted with experiments looking at 31 00:01:36,550 --> 00:01:35,040 the earth and looking at space 32 00:01:38,310 --> 00:01:36,560 so this is a 33 00:01:40,149 --> 00:01:38,320 module like all the other laboratories 34 00:01:41,749 --> 00:01:40,159 here behind all the walls just filled 35 00:01:42,630 --> 00:01:41,759 with the experiments and racks that we 36 00:01:45,030 --> 00:01:42,640 work on 37 00:01:47,030 --> 00:01:45,040 so that's my location now and and you're 38 00:01:49,030 --> 00:01:47,040 right this is the uh come to the end of 39 00:01:50,789 --> 00:01:49,040 a four month mission feeling 40 00:01:52,069 --> 00:01:50,799 adapted feeling great 41 00:01:53,590 --> 00:01:52,079 it's been 42 00:01:54,950 --> 00:01:53,600 wonderful being able to be efficient and 43 00:01:57,990 --> 00:01:54,960 get a lot done up here it's very 44 00:02:03,510 --> 00:02:00,950 well in the early part of the space 45 00:02:05,429 --> 00:02:03,520 shuttle program we never had any time to 46 00:02:08,070 --> 00:02:05,439 get to the window 47 00:02:09,910 --> 00:02:08,080 because every minute was planned with 48 00:02:11,750 --> 00:02:09,920 our experiments or else we were supposed 49 00:02:13,990 --> 00:02:11,760 to be sleeping 50 00:02:16,710 --> 00:02:14,000 many times of which we didn't that's 51 00:02:19,830 --> 00:02:16,720 when we had time to get to the window 52 00:02:25,350 --> 00:02:19,840 uh do you have a lot of time to look 53 00:02:30,150 --> 00:02:27,350 well actually during the day not a lot 54 00:02:31,830 --> 00:02:30,160 of time uh now one of our experiments 55 00:02:34,790 --> 00:02:31,840 one of our payloads we call them that we 56 00:02:36,630 --> 00:02:34,800 are participating in is crew earth 57 00:02:38,550 --> 00:02:36,640 observations looking at uh flooding 58 00:02:40,630 --> 00:02:38,560 sites i was just we were just flying 59 00:02:41,830 --> 00:02:40,640 over saudi arabia earlier today looking 60 00:02:43,750 --> 00:02:41,840 at some of the flooding that's been 61 00:02:45,350 --> 00:02:43,760 occurring there getting photographs to 62 00:02:46,949 --> 00:02:45,360 the ground right away for disaster 63 00:02:48,390 --> 00:02:46,959 response or for a better understanding 64 00:02:51,270 --> 00:02:48,400 of what's going on in that part of the 65 00:02:53,110 --> 00:02:51,280 world so immediate immediate contact 66 00:02:54,550 --> 00:02:53,120 with the earth that's when we can see 67 00:02:56,630 --> 00:02:54,560 the earth have time to see the earth 68 00:02:59,270 --> 00:02:56,640 during the day but you're right it's at 69 00:03:01,030 --> 00:02:59,280 night time usually past the sleep time 70 00:03:02,630 --> 00:03:01,040 that we get a chance to float up to the 71 00:03:03,670 --> 00:03:02,640 window or with our colleagues and spend 72 00:03:05,830 --> 00:03:03,680 some time 73 00:03:11,030 --> 00:03:05,840 looking out the window and they're as 74 00:03:16,070 --> 00:03:13,910 well in the cupola 75 00:03:17,830 --> 00:03:16,080 i understand it's almost like three 76 00:03:19,990 --> 00:03:17,840 dimension 77 00:03:24,390 --> 00:03:20,000 what's it like to look back at the earth 78 00:03:29,190 --> 00:03:27,430 well i i wish every head of state around 79 00:03:32,630 --> 00:03:29,200 the world could come and see our earth 80 00:03:34,869 --> 00:03:32,640 from the cupola it is a 360 degree view 81 00:03:36,309 --> 00:03:34,879 and directly overhead overhead is the 82 00:03:39,270 --> 00:03:36,319 earth so we're actually from an earth 83 00:03:41,430 --> 00:03:39,280 standpoint to have our heads down 84 00:03:42,949 --> 00:03:41,440 but i've found that i've fallen in love 85 00:03:44,309 --> 00:03:42,959 with the earth again 86 00:03:47,509 --> 00:03:44,319 the 87 00:03:50,470 --> 00:03:47,519 incredible 88 00:03:51,990 --> 00:03:50,480 beauty nuance uh the colors the variants 89 00:03:55,270 --> 00:03:52,000 from country to country and from season 90 00:03:56,630 --> 00:03:55,280 to season is uh is remarkable and it's 91 00:03:58,390 --> 00:03:56,640 impossible to pull you're almost 92 00:03:59,509 --> 00:03:58,400 impossible to pull your eyes away from 93 00:04:02,390 --> 00:03:59,519 it 94 00:04:04,309 --> 00:04:02,400 what strikes every astronaut is that 95 00:04:05,910 --> 00:04:04,319 there are no borders down there and that 96 00:04:07,830 --> 00:04:05,920 with our lives with our international 97 00:04:09,589 --> 00:04:07,840 partners up here 98 00:04:12,470 --> 00:04:09,599 knocks down a lot of the barriers that 99 00:04:14,149 --> 00:04:12,480 we have for for 100 00:04:15,910 --> 00:04:14,159 getting getting through technological 101 00:04:17,990 --> 00:04:15,920 difficulties and language difficulties 102 00:04:19,270 --> 00:04:18,000 and and cultural differences and we 103 00:04:21,509 --> 00:04:19,280 actually share that looking out the 104 00:04:23,189 --> 00:04:21,519 window together so the earth is riveting 105 00:04:25,110 --> 00:04:23,199 it's beautiful uh 106 00:04:27,270 --> 00:04:25,120 our existence on there appears to be 107 00:04:29,430 --> 00:04:27,280 very fragile the atmosphere is very thin 108 00:04:31,189 --> 00:04:29,440 so we try to get pictures to convey that 109 00:04:33,189 --> 00:04:31,199 to everyone on the ground it really 110 00:04:37,749 --> 00:04:33,199 changes the way you see the earth and 111 00:04:42,390 --> 00:04:40,150 tom you look pretty good you look like 112 00:04:45,189 --> 00:04:42,400 you're physically fit 113 00:04:46,790 --> 00:04:45,199 uh we've been concerned that there's 114 00:04:50,230 --> 00:04:46,800 bone loss 115 00:04:51,830 --> 00:04:50,240 in zero g for extended periods of time 116 00:04:54,310 --> 00:04:51,840 tell us about the things that you're 117 00:04:56,790 --> 00:04:54,320 trying to do to keep yourself in shape 118 00:04:59,749 --> 00:04:56,800 which you obviously have 119 00:05:01,189 --> 00:04:59,759 and how do you adjust to the fact that 120 00:05:03,590 --> 00:05:01,199 the fluids 121 00:05:08,230 --> 00:05:03,600 shift into the upper torso outside of 122 00:05:11,510 --> 00:05:09,590 we're exactly right that's one of the 123 00:05:13,670 --> 00:05:11,520 biggest challenges uh another way of 124 00:05:14,950 --> 00:05:13,680 putting that actually the zero gravity 125 00:05:17,110 --> 00:05:14,960 and the atrophy that occurs in the 126 00:05:19,270 --> 00:05:17,120 muscles and the bones and our heart and 127 00:05:21,270 --> 00:05:19,280 blood vessels as well that on top of the 128 00:05:23,110 --> 00:05:21,280 radiation we're getting from the outside 129 00:05:25,430 --> 00:05:23,120 uh high radiation doses up here where 130 00:05:27,749 --> 00:05:25,440 all radiation workers all of that is 131 00:05:30,390 --> 00:05:27,759 accelerates it's it's an analog for 132 00:05:32,310 --> 00:05:30,400 acceleration of the aging process so it 133 00:05:33,510 --> 00:05:32,320 actually offers an opportunity to do a 134 00:05:35,110 --> 00:05:33,520 lot of research 135 00:05:37,110 --> 00:05:35,120 you can do in a few years what you can 136 00:05:40,390 --> 00:05:37,120 only do on the ground in decades through 137 00:05:41,270 --> 00:05:40,400 the final years of someone's life 138 00:05:42,870 --> 00:05:41,280 so 139 00:05:45,029 --> 00:05:42,880 what we've been doing is research on 140 00:05:46,390 --> 00:05:45,039 that area i believe that we're getting 141 00:05:48,390 --> 00:05:46,400 close to solving the problem for the 142 00:05:49,749 --> 00:05:48,400 bone and muscle atrophy that you've 143 00:05:51,909 --> 00:05:49,759 alluded to 144 00:05:53,830 --> 00:05:51,919 we i'll exercise two and a half hours a 145 00:05:56,550 --> 00:05:53,840 day a little bit of cardiovascular a lot 146 00:05:58,710 --> 00:05:56,560 of resistance exercise uh we i'm 147 00:06:00,150 --> 00:05:58,720 participating right now on the subject 148 00:06:02,550 --> 00:06:00,160 in an experiment where we're looking at 149 00:06:05,749 --> 00:06:02,560 dietary changes it's called pro-k 150 00:06:07,270 --> 00:06:05,759 and seeing if we can tweak the diet 151 00:06:09,590 --> 00:06:07,280 with the right protein to potassium 152 00:06:11,430 --> 00:06:09,600 ratio to actually 153 00:06:13,189 --> 00:06:11,440 reduce bone loss 154 00:06:15,350 --> 00:06:13,199 our food group has also worked very hard 155 00:06:16,550 --> 00:06:15,360 on changing our food reducing the salt 156 00:06:18,150 --> 00:06:16,560 in the food 157 00:06:19,830 --> 00:06:18,160 and has actually been invited to a lot 158 00:06:21,830 --> 00:06:19,840 of conferences around the country 159 00:06:23,510 --> 00:06:21,840 because the food is great it's wonderful 160 00:06:25,909 --> 00:06:23,520 it's great tasting and it's relatively 161 00:06:28,390 --> 00:06:25,919 low in salt so again we don't leech the 162 00:06:31,029 --> 00:06:28,400 the bone out of our bodies so these are 163 00:06:31,830 --> 00:06:31,039 all avenues that we're working on 164 00:06:36,550 --> 00:06:31,840 to 165 00:06:38,469 --> 00:06:36,560 heart and our blood vessel status 166 00:06:39,909 --> 00:06:38,479 feel great i think i'm going to 167 00:06:41,909 --> 00:06:39,919 certainly be ready to stand up and walk 168 00:06:46,150 --> 00:06:41,919 around when i get back to the earth but 169 00:06:50,629 --> 00:06:47,909 so you've been there four and a half 170 00:06:52,790 --> 00:06:50,639 months uh do you think when you first 171 00:06:57,350 --> 00:06:52,800 stand up back on earth you'll be able to 172 00:07:00,870 --> 00:06:59,589 i think so i was able to after my 173 00:07:03,110 --> 00:07:00,880 shuttle flight 174 00:07:05,350 --> 00:07:03,120 i didn't exercise as much on the shuttle 175 00:07:06,870 --> 00:07:05,360 flight as i have here i've been very 176 00:07:08,150 --> 00:07:06,880 diligent about it 177 00:07:09,990 --> 00:07:08,160 there will be people around if there's 178 00:07:12,150 --> 00:07:10,000 any problems there's a lot of variants 179 00:07:14,070 --> 00:07:12,160 amongst astronauts about how they adapt 180 00:07:15,830 --> 00:07:14,080 when they arrive and when they 181 00:07:17,430 --> 00:07:15,840 when they come back so we don't know 182 00:07:20,230 --> 00:07:17,440 everything about it but i certainly hope 183 00:07:21,830 --> 00:07:20,240 so i intend on trying to stand up uh i'm 184 00:07:23,430 --> 00:07:21,840 going to take some fluids into my body 185 00:07:25,029 --> 00:07:23,440 either through an iv or drinking some 186 00:07:27,189 --> 00:07:25,039 water because you may know that we lose 187 00:07:28,309 --> 00:07:27,199 body fluids up here as well our body 188 00:07:30,150 --> 00:07:28,319 interprets 189 00:07:32,309 --> 00:07:30,160 zero gravity by saying hey there's too 190 00:07:35,589 --> 00:07:32,319 much fluid on board and it gets rid of 191 00:07:37,270 --> 00:07:35,599 it it adapts very well to space and so 192 00:07:39,110 --> 00:07:37,280 it takes some time to adapt again to the 193 00:07:41,430 --> 00:07:39,120 ground when you get back so all of that 194 00:07:42,710 --> 00:07:41,440 together i think we're prepared 195 00:07:43,990 --> 00:07:42,720 there's a lot of interesting research in 196 00:07:47,990 --> 00:07:44,000 that area as well but i think we're 197 00:07:52,390 --> 00:07:49,909 well when you get back i want you to 198 00:07:53,670 --> 00:07:52,400 tell me if you were able to stand 199 00:07:57,589 --> 00:07:53,680 immediately 200 00:08:00,070 --> 00:07:57,599 i tried and i fell right over 201 00:08:02,390 --> 00:08:00,080 i want to introduce 202 00:08:05,670 --> 00:08:02,400 senator ted cruz 203 00:08:07,510 --> 00:08:05,680 my co-leader of the 204 00:08:09,830 --> 00:08:07,520 science and space subcommittee of the 205 00:08:10,869 --> 00:08:09,840 commerce committee senator cruz is from 206 00:08:12,790 --> 00:08:10,879 texas 207 00:08:15,909 --> 00:08:12,800 his hometown as a matter of fact is 208 00:08:18,230 --> 00:08:15,919 houston but he's on the opposite side uh 209 00:08:21,029 --> 00:08:18,240 clear lake you're on the 210 00:08:22,230 --> 00:08:21,039 southeast side he's over a little bit to 211 00:08:24,390 --> 00:08:22,240 the west 212 00:08:26,390 --> 00:08:24,400 senator cruz 213 00:08:28,629 --> 00:08:26,400 thank you senator nelson i want to thank 214 00:08:32,230 --> 00:08:28,639 you dr marshburn for your service and 215 00:08:34,709 --> 00:08:32,240 and i'd love to just ask a question uh 216 00:08:36,070 --> 00:08:34,719 what surprised you the most about your 217 00:08:37,909 --> 00:08:36,080 time on the space station is there 218 00:08:40,070 --> 00:08:37,919 something you didn't expect that now 219 00:08:44,630 --> 00:08:40,080 four and a half months into it has 220 00:08:50,790 --> 00:08:46,550 yes what surprised me 221 00:08:53,110 --> 00:08:50,800 uh was that how busy and vibrant life 222 00:08:55,430 --> 00:08:53,120 and the work here on the space station 223 00:08:56,710 --> 00:08:55,440 is the space station is a hard place to 224 00:08:58,630 --> 00:08:56,720 go to sleep 225 00:09:01,430 --> 00:08:58,640 because if it's not looking out the 226 00:09:03,910 --> 00:09:01,440 window it is every moment enjoying the 227 00:09:06,790 --> 00:09:03,920 effects of zero gravity and especially 228 00:09:09,190 --> 00:09:06,800 the work during the day we are busy as 229 00:09:10,870 --> 00:09:09,200 can be and in a wonderful way 230 00:09:11,910 --> 00:09:10,880 we've just you may know we've just uh 231 00:09:14,070 --> 00:09:11,920 added 232 00:09:15,590 --> 00:09:14,080 up to four comm loops we can talk to 233 00:09:17,190 --> 00:09:15,600 scientists all around the world and if 234 00:09:19,190 --> 00:09:17,200 for a few days we've had every loop 235 00:09:21,350 --> 00:09:19,200 socked in with conversation with 236 00:09:23,590 --> 00:09:21,360 scientists as we do experiments there's 237 00:09:25,829 --> 00:09:23,600 so much going on up here it's it's just 238 00:09:28,230 --> 00:09:25,839 hard to stop quite frankly it's it's 239 00:09:29,030 --> 00:09:28,240 hard to stop and go to sleep and 240 00:09:31,590 --> 00:09:29,040 and 241 00:09:33,509 --> 00:09:31,600 leave it alone for a while so that's 242 00:09:37,829 --> 00:09:33,519 very honestly that is what shocked me 243 00:09:41,750 --> 00:09:39,750 is there particular research that you're 244 00:09:44,790 --> 00:09:41,760 working on now that you're able to 245 00:09:49,269 --> 00:09:44,800 discuss that you think is is exciting or 246 00:09:52,310 --> 00:09:51,509 i actually i don't know where to start 247 00:09:54,870 --> 00:09:52,320 um 248 00:09:57,509 --> 00:09:54,880 being a doctor i'll be uh preferential 249 00:09:59,590 --> 00:09:57,519 to to those experiments just yesterday i 250 00:10:01,430 --> 00:09:59,600 was finalizing our uh 251 00:10:03,190 --> 00:10:01,440 i was the first subject along with my 252 00:10:04,470 --> 00:10:03,200 colleagues first subjects in the spinal 253 00:10:06,069 --> 00:10:04,480 ultrasound study 254 00:10:08,230 --> 00:10:06,079 using ultrasound as we all know it on 255 00:10:10,069 --> 00:10:08,240 the ground but in a very novel way 256 00:10:11,590 --> 00:10:10,079 looking at our spines doing something 257 00:10:14,310 --> 00:10:11,600 that's good for human space flight that 258 00:10:15,750 --> 00:10:14,320 is figuring out what is the cause of 259 00:10:17,269 --> 00:10:15,760 back pain which is something that occurs 260 00:10:19,110 --> 00:10:17,279 in some astronauts 261 00:10:21,269 --> 00:10:19,120 particularly maybe even back injury when 262 00:10:23,269 --> 00:10:21,279 we get back to the earth and we put our 263 00:10:24,870 --> 00:10:23,279 spine under compression again 264 00:10:27,910 --> 00:10:24,880 and comparing these ultrasound images to 265 00:10:29,509 --> 00:10:27,920 mri now we have ultrasound 266 00:10:31,590 --> 00:10:29,519 on the ground obviously they don't 267 00:10:32,870 --> 00:10:31,600 usually use it for the back 268 00:10:35,590 --> 00:10:32,880 but what's 269 00:10:38,069 --> 00:10:35,600 very exciting about this is that we are 270 00:10:40,949 --> 00:10:38,079 finding ways to use ultrasound even 271 00:10:43,509 --> 00:10:40,959 being able to visualize the spinal cord 272 00:10:45,910 --> 00:10:43,519 in ways that are completely unexpected 273 00:10:47,269 --> 00:10:45,920 there are countries and obviously places 274 00:10:50,230 --> 00:10:47,279 even in the united states where there 275 00:10:52,550 --> 00:10:50,240 are no mris are no cat scanners even in 276 00:10:55,030 --> 00:10:52,560 emergency rooms where the wait is eight 277 00:10:57,590 --> 00:10:55,040 to ten hours in the middle of a city 278 00:10:59,350 --> 00:10:57,600 this is one example a small example but 279 00:11:01,670 --> 00:10:59,360 one example of how 280 00:11:03,990 --> 00:11:01,680 nasa is using a current technology 281 00:11:05,269 --> 00:11:04,000 applying it to a very difficult problem 282 00:11:06,710 --> 00:11:05,279 that is bringing medical care to 283 00:11:08,310 --> 00:11:06,720 astronauts where we don't have a 284 00:11:10,069 --> 00:11:08,320 hospital up here 285 00:11:12,630 --> 00:11:10,079 and that has developed techniques and 286 00:11:14,150 --> 00:11:12,640 processes that can be used on the earth 287 00:11:17,110 --> 00:11:14,160 that's been done many times as a matter 288 00:11:19,269 --> 00:11:17,120 of fact i'll just have to say 289 00:11:20,949 --> 00:11:19,279 training for every surgical resident in 290 00:11:23,829 --> 00:11:20,959 the united states right now 291 00:11:25,990 --> 00:11:23,839 uses a technique that was developed by 292 00:11:28,389 --> 00:11:26,000 people that were solving a problem for 293 00:11:30,710 --> 00:11:28,399 nasa onboard the space station 294 00:11:32,310 --> 00:11:30,720 that is very essential for trauma care 295 00:11:34,470 --> 00:11:32,320 in the first hour 296 00:11:35,750 --> 00:11:34,480 it's saving lives right now this is a 297 00:11:38,150 --> 00:11:35,760 part of training for every resident 298 00:11:39,829 --> 00:11:38,160 surgical resident and surgeon in the u.s 299 00:11:41,670 --> 00:11:39,839 right now it's been adopted it came 300 00:11:43,990 --> 00:11:41,680 completely from the desire to provide 301 00:11:46,069 --> 00:11:44,000 medical care for astronauts 302 00:11:48,470 --> 00:11:46,079 so and that was an ultrasound technique 303 00:11:49,829 --> 00:11:48,480 as well so i'm very excited about it as 304 00:11:52,790 --> 00:11:49,839 a doctor but i think it's a great 305 00:11:54,870 --> 00:11:52,800 example of what happens when you ask 306 00:11:57,269 --> 00:11:54,880 very smart people to do a very hard 307 00:11:59,030 --> 00:11:57,279 thing and tell them also you're helping 308 00:12:00,629 --> 00:11:59,040 the exploration of the universe 309 00:12:04,790 --> 00:12:00,639 it's a great combination and wonderful 310 00:12:04,800 --> 00:12:07,750 terrific thank you 311 00:12:14,230 --> 00:12:10,790 tell us about are you still doing 312 00:12:16,949 --> 00:12:14,240 crystal growth in zero g 313 00:12:19,509 --> 00:12:16,959 and if not 314 00:12:21,990 --> 00:12:19,519 what are some of the promising 315 00:12:23,350 --> 00:12:22,000 medical research 316 00:12:26,230 --> 00:12:23,360 experiments 317 00:12:33,269 --> 00:12:26,240 for example in the development of drugs 318 00:12:37,110 --> 00:12:35,269 there is crystallography and crystal 319 00:12:38,870 --> 00:12:37,120 research going on right now particularly 320 00:12:40,389 --> 00:12:38,880 in this module in the japanese 321 00:12:43,509 --> 00:12:40,399 experiment module 322 00:12:45,509 --> 00:12:43,519 that is one experiment we we are 323 00:12:47,590 --> 00:12:45,519 astronauts are subjects as well as 324 00:12:49,829 --> 00:12:47,600 surrogate scientists but we're also lab 325 00:12:52,389 --> 00:12:49,839 technicians we get things going and let 326 00:12:53,670 --> 00:12:52,399 them run and the crystal growth 327 00:12:56,150 --> 00:12:53,680 experiments there's several of them 328 00:12:57,990 --> 00:12:56,160 actually and we stock them we let get 329 00:12:59,430 --> 00:12:58,000 them going and then we resupply them to 330 00:13:01,269 --> 00:12:59,440 the ground 331 00:13:02,790 --> 00:13:01,279 so that's going on all the time 332 00:13:04,069 --> 00:13:02,800 in my opinion one of the greatest 333 00:13:05,990 --> 00:13:04,079 achievements recently on the space 334 00:13:08,389 --> 00:13:06,000 station is the ability to turn that into 335 00:13:10,870 --> 00:13:08,399 a an assembly line a process whereby we 336 00:13:13,430 --> 00:13:10,880 can bring up lots of samples of crystals 337 00:13:14,790 --> 00:13:13,440 lots of samples of proteins 338 00:13:16,550 --> 00:13:14,800 and then 339 00:13:18,310 --> 00:13:16,560 put them up in these laboratories return 340 00:13:19,910 --> 00:13:18,320 them to the earth and then companies and 341 00:13:21,509 --> 00:13:19,920 scientists universities can go back and 342 00:13:23,670 --> 00:13:21,519 look at them and 343 00:13:25,590 --> 00:13:23,680 really define proteins to a level 344 00:13:27,670 --> 00:13:25,600 they've never been able to before uh 345 00:13:29,190 --> 00:13:27,680 you're probably familiar with uh 346 00:13:31,509 --> 00:13:29,200 better description of the genes that 347 00:13:33,990 --> 00:13:31,519 cause duchene's muscular dystrophy 348 00:13:35,750 --> 00:13:34,000 there's a 349 00:13:38,230 --> 00:13:35,760 any number of drugs that have been uh 350 00:13:40,310 --> 00:13:38,240 coming through it's fairly rare that a 351 00:13:42,310 --> 00:13:40,320 useful um 352 00:13:44,310 --> 00:13:42,320 application is discovered but now with 353 00:13:46,389 --> 00:13:44,320 the accelerated numbers that we're able 354 00:13:50,310 --> 00:13:46,399 to process up here on the space station 355 00:13:51,509 --> 00:13:50,320 i feel that the the uh the findings and 356 00:13:52,949 --> 00:13:51,519 the discoveries are going to be 357 00:13:55,910 --> 00:13:52,959 accelerating coming out much more 358 00:13:58,470 --> 00:13:55,920 frequent much quicker much more quickly 359 00:14:00,629 --> 00:13:58,480 uh other things outside crystallography 360 00:14:03,030 --> 00:14:00,639 uh you're probably familiar with the 361 00:14:04,790 --> 00:14:03,040 salmonella vaccine which came out of 362 00:14:07,910 --> 00:14:04,800 being able to bring up is something no 363 00:14:09,829 --> 00:14:07,920 one ever expected but bring up bacteria 364 00:14:10,870 --> 00:14:09,839 microorganisms up here and they actually 365 00:14:13,110 --> 00:14:10,880 change 366 00:14:15,269 --> 00:14:13,120 probably due to microgravity and become 367 00:14:17,269 --> 00:14:15,279 more virulent and therefore there are 368 00:14:19,590 --> 00:14:17,279 much better test cases for producing 369 00:14:21,670 --> 00:14:19,600 vaccines we can get to the answer of the 370 00:14:24,230 --> 00:14:21,680 proper vaccine much faster because of 371 00:14:27,350 --> 00:14:24,240 these super microorganisms that that 372 00:14:29,509 --> 00:14:27,360 occur up here that can grow up here 373 00:14:31,590 --> 00:14:29,519 along the medical field 374 00:14:33,829 --> 00:14:31,600 another thing so much of this is 375 00:14:35,269 --> 00:14:33,839 unexpected there's a capillary flow 376 00:14:36,069 --> 00:14:35,279 experimental just working on the other 377 00:14:38,790 --> 00:14:36,079 day 378 00:14:40,710 --> 00:14:38,800 the intent is to provide 379 00:14:42,550 --> 00:14:40,720 fuel tanks for spacecraft that don't 380 00:14:44,470 --> 00:14:42,560 have to have pumps just use capillary 381 00:14:46,790 --> 00:14:44,480 flow well it turns out 382 00:14:49,350 --> 00:14:46,800 micro flow the flow of micro liters of 383 00:14:51,750 --> 00:14:49,360 fluid can use this technology as well 384 00:14:53,750 --> 00:14:51,760 and they've been working on producing 385 00:14:55,350 --> 00:14:53,760 better lab on a chip technology so you 386 00:14:58,150 --> 00:14:55,360 can have a greater 387 00:14:59,430 --> 00:14:58,160 suite of laboratory analysis you can do 388 00:15:01,509 --> 00:14:59,440 on blood 389 00:15:03,670 --> 00:15:01,519 just on a chip so put a cd and a little 390 00:15:05,030 --> 00:15:03,680 disc and uh get a blood analysis 391 00:15:07,110 --> 00:15:05,040 accomplished 392 00:15:09,829 --> 00:15:07,120 the list goes on i hope i'm not talking 393 00:15:11,350 --> 00:15:09,839 too much but it's it's very hard to say 394 00:15:12,790 --> 00:15:11,360 in just a few minutes everything that's 395 00:15:15,670 --> 00:15:12,800 going on particularly in the medical 396 00:15:20,790 --> 00:15:18,790 tom what is it about zero g 397 00:15:23,430 --> 00:15:20,800 that is causing 398 00:15:30,150 --> 00:15:26,470 differences in the production of a 399 00:15:32,150 --> 00:15:30,160 vaccine for mrsa and i also for for 400 00:15:36,949 --> 00:15:32,160 salmonella and i also understand for 401 00:15:41,749 --> 00:15:39,670 yes sir for mrsa as well 402 00:15:43,430 --> 00:15:41,759 that's a great question 403 00:15:44,949 --> 00:15:43,440 and i'm sure that there are scientists 404 00:15:45,910 --> 00:15:44,959 that can answer it much better than i 405 00:15:47,110 --> 00:15:45,920 could 406 00:15:49,590 --> 00:15:47,120 if just 407 00:15:51,030 --> 00:15:49,600 on my somewhat layman's 408 00:15:52,829 --> 00:15:51,040 knowledge on it 409 00:15:55,110 --> 00:15:52,839 every cell has a 410 00:15:57,910 --> 00:15:55,120 cytoskeleton there are changes to that 411 00:16:00,550 --> 00:15:57,920 cytoskeleton because of zero gravity how 412 00:16:03,030 --> 00:16:00,560 that changes gene expression within the 413 00:16:04,550 --> 00:16:03,040 cell within the microorganism i don't 414 00:16:06,870 --> 00:16:04,560 know the answer to that 415 00:16:08,790 --> 00:16:06,880 maybe it's not microgravity maybe it's 416 00:16:09,749 --> 00:16:08,800 potentially the the radiation 417 00:16:11,670 --> 00:16:09,759 environment 418 00:16:14,230 --> 00:16:11,680 although they're somewhat protected here 419 00:16:16,150 --> 00:16:14,240 i think it is microgravity but it's a 420 00:16:18,629 --> 00:16:16,160 great example of 421 00:16:20,870 --> 00:16:18,639 of we're we're in our infancy here and 422 00:16:23,189 --> 00:16:20,880 seeing what the benefits of doing 423 00:16:23,990 --> 00:16:23,199 research in microgravity are 424 00:16:25,910 --> 00:16:24,000 and 425 00:16:27,670 --> 00:16:25,920 so i i can't answer your question but i 426 00:16:29,269 --> 00:16:27,680 would love to know the answer i would 427 00:16:30,710 --> 00:16:29,279 love to talk to the experts that maybe 428 00:16:34,389 --> 00:16:30,720 are coming close to an answer to that 429 00:16:39,910 --> 00:16:36,790 let me ask a a lighter question on on a 430 00:16:42,310 --> 00:16:39,920 more personal side which is 431 00:16:43,590 --> 00:16:42,320 what do you do for recreation up there 432 00:16:47,910 --> 00:16:43,600 are there 433 00:16:52,790 --> 00:16:47,920 games you play nerf golf in zero g or 434 00:16:56,310 --> 00:16:54,629 you know actually 435 00:16:58,550 --> 00:16:56,320 for me 436 00:16:59,990 --> 00:16:58,560 just moving around the space station is 437 00:17:01,590 --> 00:17:00,000 a lot of fun 438 00:17:02,870 --> 00:17:01,600 we can have some competitions as to who 439 00:17:04,390 --> 00:17:02,880 can get through a module without 440 00:17:05,829 --> 00:17:04,400 touching a wall or 441 00:17:08,630 --> 00:17:05,839 who can stay free floating for the 442 00:17:10,390 --> 00:17:08,640 longest time without touching a wall but 443 00:17:12,789 --> 00:17:10,400 just the day-to-day work 444 00:17:15,350 --> 00:17:12,799 i love the efficiencies that we build up 445 00:17:17,029 --> 00:17:15,360 as we've been here for a while learn how 446 00:17:19,909 --> 00:17:17,039 to not put anything anywhere but just 447 00:17:21,110 --> 00:17:19,919 kind of it's like uh static juggling you 448 00:17:22,630 --> 00:17:21,120 just put everything up there that just 449 00:17:24,069 --> 00:17:22,640 sits there once you get good enough at 450 00:17:26,150 --> 00:17:24,079 it and you can do a lot of work without 451 00:17:27,270 --> 00:17:26,160 having to put anything down or restrain 452 00:17:28,470 --> 00:17:27,280 it 453 00:17:30,870 --> 00:17:28,480 looking out the window is a great 454 00:17:33,830 --> 00:17:30,880 pastime we have a guitar up here we play 455 00:17:36,150 --> 00:17:33,840 guitar uh usually just by ourselves off 456 00:17:38,950 --> 00:17:36,160 into a module somewhere 457 00:17:40,230 --> 00:17:38,960 we do have some books as well but it's 458 00:17:45,350 --> 00:17:40,240 it's hard to tear yourself away from 459 00:17:50,789 --> 00:17:48,470 uh you know uh the people on earth 460 00:17:53,590 --> 00:17:50,799 don't really know a lot about what's 461 00:17:56,310 --> 00:17:53,600 going on we have uh a contraption up 462 00:17:58,150 --> 00:17:56,320 there that's as long as from one goal 463 00:18:00,789 --> 00:17:58,160 post to the other goal posts on a 464 00:18:03,190 --> 00:18:00,799 football field and all of this 465 00:18:05,190 --> 00:18:03,200 scientific experiment is going on with 466 00:18:08,390 --> 00:18:05,200 six human beings 467 00:18:10,390 --> 00:18:08,400 uh what could you tell us earthlings 468 00:18:12,230 --> 00:18:10,400 that we can do better 469 00:18:13,830 --> 00:18:12,240 to get them to understand this 470 00:18:16,070 --> 00:18:13,840 extraordinarily 471 00:18:21,190 --> 00:18:16,080 this extraordinary flying machine that 472 00:18:25,430 --> 00:18:23,270 that's a great question i i believe 473 00:18:28,230 --> 00:18:25,440 we're making inroads as we go one of my 474 00:18:30,789 --> 00:18:28,240 colleagues chris hadfield has been using 475 00:18:32,230 --> 00:18:30,799 music to tell the story of of not just 476 00:18:34,789 --> 00:18:32,240 the personal experience of living on 477 00:18:36,470 --> 00:18:34,799 space station but just a glimpse of what 478 00:18:37,750 --> 00:18:36,480 it means in terms of the science return 479 00:18:39,510 --> 00:18:37,760 as well 480 00:18:40,789 --> 00:18:39,520 social media we've been trying to use 481 00:18:41,590 --> 00:18:40,799 quite a bit 482 00:18:51,029 --> 00:18:41,600 it 483 00:18:53,029 --> 00:18:51,039 that they really do want to know what's 484 00:18:53,990 --> 00:18:53,039 going on up here they are fascinated 485 00:18:56,070 --> 00:18:54,000 with it 486 00:18:57,750 --> 00:18:56,080 they like the direct access that some of 487 00:18:59,190 --> 00:18:57,760 the social media provides so they can 488 00:19:02,230 --> 00:18:59,200 ask directly a question and get a 489 00:19:05,190 --> 00:19:02,240 response directly back from an astronaut 490 00:19:06,470 --> 00:19:05,200 so we've been exploring that a good bit 491 00:19:07,830 --> 00:19:06,480 and 492 00:19:09,750 --> 00:19:07,840 that with the events that we're having 493 00:19:11,190 --> 00:19:09,760 right now we obviously are talking to a 494 00:19:13,590 --> 00:19:11,200 lot of schools do a lot of pre-flight 495 00:19:15,750 --> 00:19:13,600 and post flight work as well 496 00:19:18,150 --> 00:19:15,760 but uh that's a great question i think 497 00:19:19,830 --> 00:19:18,160 we're getting better at it 498 00:19:23,430 --> 00:19:19,840 and we'll continue to look for better 499 00:19:29,990 --> 00:19:26,070 well you are clearly a part of that 500 00:19:32,150 --> 00:19:30,000 uh and uh we thank you uh i you know 501 00:19:34,150 --> 00:19:32,160 we're going to mars 502 00:19:37,669 --> 00:19:34,160 and uh 503 00:19:40,070 --> 00:19:37,679 and we may go back to that 504 00:19:42,150 --> 00:19:40,080 retrograde orbit where we're going to 505 00:19:45,350 --> 00:19:42,160 nudge 506 00:19:48,230 --> 00:19:45,360 a piece of space into an orbit there a 507 00:19:50,870 --> 00:19:48,240 stable orbit we may go back to the moon 508 00:19:53,669 --> 00:19:50,880 in preparation to go to mars 509 00:19:55,909 --> 00:19:53,679 what do you think on the station that 510 00:20:00,710 --> 00:19:55,919 you're doing in preparation for us to go 511 00:20:05,510 --> 00:20:03,750 well virtually everything to keep humans 512 00:20:07,669 --> 00:20:05,520 alive and productive up here on the 513 00:20:09,830 --> 00:20:07,679 space station that that is no small 514 00:20:11,909 --> 00:20:09,840 matter it's something that we get better 515 00:20:14,230 --> 00:20:11,919 at every day 516 00:20:15,510 --> 00:20:14,240 you know we we live inside of a power 517 00:20:17,909 --> 00:20:15,520 station 518 00:20:19,350 --> 00:20:17,919 that's uh the biggest one in orbit 519 00:20:20,390 --> 00:20:19,360 that's why we're able to run so many 520 00:20:22,710 --> 00:20:20,400 experiments 521 00:20:25,430 --> 00:20:22,720 we have a water system where we we 522 00:20:26,870 --> 00:20:25,440 reclaim almost 100 of our water these 523 00:20:28,950 --> 00:20:26,880 are all things that we have to be able 524 00:20:30,310 --> 00:20:28,960 to do to leave earth orbit not be able 525 00:20:31,350 --> 00:20:30,320 to resupply 526 00:20:33,190 --> 00:20:31,360 so 527 00:20:35,350 --> 00:20:33,200 i believe i'm i'm living and working in 528 00:20:37,029 --> 00:20:35,360 the first mars vehicle 529 00:20:38,390 --> 00:20:37,039 uh the the next generation is going to 530 00:20:41,270 --> 00:20:38,400 learn from everything that we have 531 00:20:43,190 --> 00:20:41,280 learned the engineers uh astronauts the 532 00:20:44,950 --> 00:20:43,200 people that build spacecraft 533 00:20:47,029 --> 00:20:44,960 everything that we've learned here 534 00:20:48,789 --> 00:20:47,039 is going to be used and needs to be used 535 00:20:49,909 --> 00:20:48,799 for the for the next generation of 536 00:20:52,310 --> 00:20:49,919 vehicle 537 00:20:54,149 --> 00:20:52,320 so i think we're doing it right now and 538 00:20:55,830 --> 00:20:54,159 we need it's not easy we have to keep 539 00:20:57,430 --> 00:20:55,840 doing it it's not a switch you can turn 540 00:20:58,789 --> 00:20:57,440 off and turn back on again and think you 541 00:21:01,510 --> 00:20:58,799 have the answer 542 00:21:05,750 --> 00:21:01,520 right away it's a process that's very 543 00:21:10,470 --> 00:21:08,149 we have four minutes left in the window 544 00:21:11,510 --> 00:21:10,480 let's give somebody in the audience a 545 00:21:14,470 --> 00:21:11,520 chance 546 00:21:16,549 --> 00:21:14,480 step up and identify yourself for tom hi 547 00:21:18,630 --> 00:21:16,559 i'm jason hopkins i work in senator bill 548 00:21:19,750 --> 00:21:18,640 nelson's office um 549 00:21:20,549 --> 00:21:19,760 uh 550 00:21:22,310 --> 00:21:20,559 so 551 00:21:24,630 --> 00:21:22,320 can you explain uh how 552 00:21:27,029 --> 00:21:24,640 you know u.s private space companies 553 00:21:31,350 --> 00:21:27,039 uh are using the iss as a technology 554 00:21:36,070 --> 00:21:33,510 well primarily uh first of all it's a 555 00:21:38,789 --> 00:21:36,080 destination uh this is a product they 556 00:21:40,789 --> 00:21:38,799 can provide and a place to go in space 557 00:21:42,549 --> 00:21:40,799 we need it we need the uh need the 558 00:21:45,029 --> 00:21:42,559 supply we need to be able to return 559 00:21:46,230 --> 00:21:45,039 results to the ground 560 00:21:48,470 --> 00:21:46,240 so 561 00:21:50,390 --> 00:21:48,480 if they can do it that is 562 00:21:52,390 --> 00:21:50,400 an incredibly impressive technology 563 00:21:55,270 --> 00:21:52,400 demonstration going into space is not 564 00:21:57,590 --> 00:21:55,280 easy we can still just barely do it 565 00:21:59,510 --> 00:21:57,600 we've had companies with some problems 566 00:22:01,430 --> 00:21:59,520 with launches that's completely expected 567 00:22:03,190 --> 00:22:01,440 because this is still a very hard thing 568 00:22:05,510 --> 00:22:03,200 to do now having said that they're 569 00:22:07,270 --> 00:22:05,520 coming up with great efficiencies great 570 00:22:09,190 --> 00:22:07,280 new technologies built on what nasa's 571 00:22:10,870 --> 00:22:09,200 already done so that they can get 572 00:22:13,270 --> 00:22:10,880 probably cheaper better faster get 573 00:22:15,190 --> 00:22:13,280 things up to the space station 574 00:22:17,669 --> 00:22:15,200 so besides everything we've learned 575 00:22:24,830 --> 00:22:17,679 about spacecraft we're also providing 576 00:22:29,510 --> 00:22:27,430 well thank you doctor for your important 577 00:22:31,750 --> 00:22:29,520 work my name is ben bradley and i just 578 00:22:34,070 --> 00:22:31,760 wanted to ask something about your daily 579 00:22:36,549 --> 00:22:34,080 routine uh what you go through 580 00:22:38,549 --> 00:22:36,559 and uh and and how that helps you 581 00:22:39,669 --> 00:22:38,559 throughout the day developing a routine 582 00:22:45,190 --> 00:22:39,679 i know you've been up there for four 583 00:22:48,630 --> 00:22:46,549 well the ground certainly helps with 584 00:22:50,789 --> 00:22:48,640 that a lot every five minutes is blocked 585 00:22:53,270 --> 00:22:50,799 out but there's some variability there 586 00:22:54,950 --> 00:22:53,280 we wake up and typically we'll read 587 00:22:57,270 --> 00:22:54,960 summaries from the ground we do we do 588 00:22:58,950 --> 00:22:57,280 our homework uh ground sends itself the 589 00:23:01,110 --> 00:22:58,960 plan for the day and why the rationale 590 00:23:02,549 --> 00:23:01,120 for the plan uh things to look out for 591 00:23:04,710 --> 00:23:02,559 we read about the experiments we might 592 00:23:05,990 --> 00:23:04,720 even start looking into the procedures 593 00:23:07,830 --> 00:23:06,000 see if there's any hiccups that might 594 00:23:09,590 --> 00:23:07,840 come up but then we just implement the 595 00:23:11,990 --> 00:23:09,600 plan that we've been given if we find 596 00:23:14,149 --> 00:23:12,000 efficiencies we try to fill fill in more 597 00:23:15,669 --> 00:23:14,159 work during that time 598 00:23:17,350 --> 00:23:15,679 you know obviously we have a little 599 00:23:19,029 --> 00:23:17,360 break for uh for a meal in the middle of 600 00:23:21,190 --> 00:23:19,039 the day we do have our two and a half 601 00:23:23,350 --> 00:23:21,200 hour block of exercise that can occur 602 00:23:25,270 --> 00:23:23,360 just about any time during the day 603 00:23:27,669 --> 00:23:25,280 so that's very much into our routine as 604 00:23:30,630 --> 00:23:27,679 well and then uh after a meal which we 605 00:23:31,909 --> 00:23:30,640 often share with our russian colleagues 606 00:23:33,350 --> 00:23:31,919 it's great to be able to get together 607 00:23:36,310 --> 00:23:33,360 and just talk about the day talk about 608 00:23:38,390 --> 00:23:36,320 the work just amongst uh colleagues we 609 00:23:39,110 --> 00:23:38,400 also have a planning conference both at 610 00:23:42,789 --> 00:23:39,120 the 611 00:23:44,710 --> 00:23:42,799 it's kind of bookended that way 612 00:23:46,950 --> 00:23:44,720 and then it's time off we do kind of 613 00:23:48,789 --> 00:23:46,960 what i described before i'm i'm partial 614 00:23:50,390 --> 00:23:48,799 to doing a little bit of homework 615 00:23:52,070 --> 00:23:50,400 at night to get ready for the following 616 00:23:53,830 --> 00:23:52,080 day as well and usually at the end of 617 00:23:56,310 --> 00:23:53,840 the day we call uh home we have an 618 00:23:59,350 -->
