00:02:31,750 --> 00:02:29,200 research center in silicon valley and i 53 00:02:32,949 --> 00:02:31,760 work on space missions fabulous 54 00:02:35,750 --> 00:02:32,959 thanks 55 00:02:37,509 --> 00:02:35,760 i'm tony culprite i'm also here at nasa 56 00:02:39,350 --> 00:02:37,519 ames research center i'm a planetary 57 00:02:41,910 --> 00:02:39,360 scientist and 58 00:02:44,869 --> 00:02:41,920 work on space instruments space missions 59 00:02:46,470 --> 00:02:44,879 uh things like that that right 60 00:02:48,309 --> 00:02:46,480 instruments too so 61 00:02:49,670 --> 00:02:48,319 we do a lot of similar stuff yeah we 62 00:02:51,190 --> 00:02:49,680 spent a lot of time in 63 00:02:53,509 --> 00:02:51,200 clean rooms 64 00:02:55,990 --> 00:02:53,519 five chambers thermal back chambers but 65 00:02:58,470 --> 00:02:56,000 not inside but not inside no no you 66 00:03:00,390 --> 00:02:58,480 don't undergo vacuum tests okay not on 67 00:03:02,949 --> 00:03:00,400 purpose yeah all right cool so let's 68 00:03:04,790 --> 00:03:02,959 start with the basics of returning 69 00:03:07,509 --> 00:03:04,800 humans to the moon when's this going to 70 00:03:11,430 --> 00:03:09,110 the clock i think up in front says 71 00:03:13,190 --> 00:03:11,440 something yeah yeah yes 72 00:03:15,910 --> 00:03:13,200 so quick do the math 73 00:03:18,470 --> 00:03:15,920 in 1656 days 74 00:03:20,229 --> 00:03:18,480 exactly eight hours 46 minutes to be 75 00:03:22,309 --> 00:03:20,239 precise that's right yeah 76 00:03:24,309 --> 00:03:22,319 counting in league years exactly this is 77 00:03:26,390 --> 00:03:24,319 not the doomsday clock 78 00:03:29,589 --> 00:03:26,400 this new clock of hours is counting down 79 00:03:31,110 --> 00:03:29,599 the days until the year 2024 which is 80 00:03:33,670 --> 00:03:31,120 when the 81 00:03:36,229 --> 00:03:33,680 first woman and the next person 82 00:03:37,990 --> 00:03:36,239 perhaps it's a man perhaps a woman will 83 00:03:39,750 --> 00:03:38,000 set foot on the moon right that's right 84 00:03:41,750 --> 00:03:39,760 that's a be a historic 85 00:03:43,910 --> 00:03:41,760 historic moment exactly yeah so let's 86 00:03:46,390 --> 00:03:43,920 talk about this mission let everybody 87 00:03:50,070 --> 00:03:46,400 know what it's called to start us off 88 00:03:51,589 --> 00:03:50,080 well um we're calling it artemis right 89 00:03:53,429 --> 00:03:51,599 so who like 90 00:03:55,509 --> 00:03:53,439 why why artemis like what's so 91 00:03:57,670 --> 00:03:55,519 significant about that name 92 00:03:58,789 --> 00:03:57,680 well she's a if you know your greek 93 00:04:01,830 --> 00:03:58,799 mythology 94 00:04:05,110 --> 00:04:01,840 because we are slowly talking great 95 00:04:06,630 --> 00:04:05,120 mythology um artemis is the twin sister 96 00:04:09,030 --> 00:04:06,640 of apollo 97 00:04:11,429 --> 00:04:09,040 that is and only appropriate yeah you 98 00:04:13,110 --> 00:04:11,439 see the connection 99 00:04:15,270 --> 00:04:13,120 for those who know about the apollo 100 00:04:17,590 --> 00:04:15,280 program that's when we did send the 101 00:04:19,509 --> 00:04:17,600 first humans um to set foot on the moon 102 00:04:21,590 --> 00:04:19,519 right exactly so the next are going 103 00:04:23,510 --> 00:04:21,600 under the artemis mission and i might 104 00:04:26,550 --> 00:04:23,520 add that when i was in fifth grade we 105 00:04:27,909 --> 00:04:26,560 did greek mythology and my goddess was 106 00:04:29,749 --> 00:04:27,919 artemis 107 00:04:31,430 --> 00:04:29,759 i'm pretty sure that played into the 108 00:04:34,150 --> 00:04:31,440 choice of the name for the missions and 109 00:04:35,749 --> 00:04:34,160 she's also a great goddess your destiny 110 00:04:37,110 --> 00:04:35,759 it was right that's right i'm very 111 00:04:40,390 --> 00:04:37,120 excited for this 112 00:04:42,310 --> 00:04:40,400 so why the moon what is so exciting for 113 00:04:44,870 --> 00:04:42,320 a couple of scientists about going back 114 00:04:49,110 --> 00:04:44,880 to the moon oh boy where to start 115 00:04:51,510 --> 00:04:49,120 um the moon is a spectacular place it's 116 00:04:53,350 --> 00:04:51,520 it's our nearest neighbor it's a 117 00:04:55,110 --> 00:04:53,360 treasure trove of science 118 00:04:56,390 --> 00:04:55,120 of exploration it's it's a place where 119 00:04:58,070 --> 00:04:56,400 we can learn about 120 00:05:01,189 --> 00:04:58,080 the history of the earth in our solar 121 00:05:03,749 --> 00:05:01,199 system it's also uh really a launching 122 00:05:04,629 --> 00:05:03,759 pad in terms of our exploration beyond 123 00:05:06,550 --> 00:05:04,639 earth 124 00:05:08,710 --> 00:05:06,560 there's uh resources there we can 125 00:05:11,430 --> 00:05:08,720 utilize to explore 126 00:05:12,390 --> 00:05:11,440 but there's also just the opportunity 127 00:05:15,270 --> 00:05:12,400 to 128 00:05:18,390 --> 00:05:15,280 test our abilities our technologies our 129 00:05:20,150 --> 00:05:18,400 processes for extended missions beyond 130 00:05:22,710 --> 00:05:20,160 the moon to mars for example that's the 131 00:05:24,790 --> 00:05:22,720 ultimate destination beyond 132 00:05:27,830 --> 00:05:24,800 the moon right now but even beyond that 133 00:05:30,230 --> 00:05:27,840 asteroids and other places wow so it's a 134 00:05:33,270 --> 00:05:30,240 it's a huge sandbox if you will to 135 00:05:36,150 --> 00:05:33,280 really learn in and and and demonstrate 136 00:05:38,390 --> 00:05:36,160 what we can do to explore yeah well said 137 00:05:40,230 --> 00:05:38,400 yeah and also um looking at just the 138 00:05:42,950 --> 00:05:40,240 moon itself um 139 00:05:44,870 --> 00:05:42,960 we know a lot about it but 140 00:05:47,990 --> 00:05:44,880 we've not really visited 141 00:05:49,590 --> 00:05:48,000 a lot fraction of the surface or even 142 00:05:50,950 --> 00:05:49,600 the environment of the moon okay so 143 00:05:53,270 --> 00:05:50,960 there's a lot of mysteries still yet to 144 00:05:55,350 --> 00:05:53,280 be uncovered yeah just on the surface 145 00:05:57,430 --> 00:05:55,360 and underneath the surface okay 146 00:05:58,390 --> 00:05:57,440 and yeah absolutely and 147 00:05:59,909 --> 00:05:58,400 you know we 148 00:06:02,309 --> 00:05:59,919 mentioned the apollo program we've been 149 00:06:04,390 --> 00:06:02,319 there robotically we have a robot 150 00:06:06,309 --> 00:06:04,400 spacecraft orbiting it now 151 00:06:08,309 --> 00:06:06,319 but we've only barely scratched the 152 00:06:10,230 --> 00:06:08,319 surface in terms of the amount of area 153 00:06:12,390 --> 00:06:10,240 we've explored on the moon there's so 154 00:06:14,870 --> 00:06:12,400 much more to learn imagine awesome all 155 00:06:15,909 --> 00:06:14,880 right so you were anxiously anticipating 156 00:06:17,870 --> 00:06:15,919 very 157 00:06:20,790 --> 00:06:17,880 uh 158 00:06:22,390 --> 00:06:20,800 656 days from now 159 00:06:24,309 --> 00:06:22,400 you'll be watching that clock closely i 160 00:06:26,150 --> 00:06:24,319 guess all right so tell us a little bit 161 00:06:28,390 --> 00:06:26,160 more specifically where are we sending 162 00:06:30,550 --> 00:06:28,400 astronauts in 2024 163 00:06:32,550 --> 00:06:30,560 well this is what i was gonna actually 164 00:06:34,070 --> 00:06:32,560 just say was what's really really 165 00:06:35,830 --> 00:06:34,080 exciting is where we are going where 166 00:06:37,590 --> 00:06:35,840 we've never been before and that's to 167 00:06:40,070 --> 00:06:37,600 one of the poles of the moon and very 168 00:06:41,909 --> 00:06:40,080 specifically the south pole of the moon 169 00:06:43,029 --> 00:06:41,919 which is my favorite pole it is if you 170 00:06:45,029 --> 00:06:43,039 have to have a favorite pole that's my 171 00:06:47,270 --> 00:06:45,039 favorite i hope it doesn't yeah 172 00:06:48,950 --> 00:06:47,280 exactly and and it's it's an incredible 173 00:06:51,510 --> 00:06:48,960 place um 174 00:06:52,390 --> 00:06:51,520 and we can talk about that as we go but 175 00:06:58,950 --> 00:06:52,400 uh 176 00:07:00,830 --> 00:06:58,960 moving shadows extreme temperatures it's 177 00:07:02,469 --> 00:07:00,840 it's unlike anywhere we've ever 178 00:07:03,670 --> 00:07:02,479 visited so cool in the solar system and 179 00:07:05,749 --> 00:07:03,680 we are going to talk all about that 180 00:07:08,230 --> 00:07:05,759 later i'm excited for that um but you 181 00:07:09,990 --> 00:07:08,240 mentioned resources now there's water 182 00:07:13,430 --> 00:07:10,000 there isn't there 183 00:07:17,670 --> 00:07:15,990 true statement okay so why why is that 184 00:07:19,749 --> 00:07:17,680 so important obviously i know humans 185 00:07:21,749 --> 00:07:19,759 need water to survive but but what do 186 00:07:24,150 --> 00:07:21,759 you see us using that for 187 00:07:25,110 --> 00:07:24,160 lots of other purposes right yeah 188 00:07:27,909 --> 00:07:25,120 um 189 00:07:30,390 --> 00:07:27,919 well water is is key in the 190 00:07:32,550 --> 00:07:30,400 water is so important for two different 191 00:07:34,230 --> 00:07:32,560 reasons one it's it's incredibly 192 00:07:36,070 --> 00:07:34,240 scientifically interesting 193 00:07:37,749 --> 00:07:36,080 and understanding the water that we now 194 00:07:39,670 --> 00:07:37,759 know exists on the moon is really 195 00:07:40,950 --> 00:07:39,680 important to understanding the processes 196 00:07:42,629 --> 00:07:40,960 that have acted on the moon and the 197 00:07:45,189 --> 00:07:42,639 earth over the last several billion 198 00:07:47,029 --> 00:07:45,199 years oh wow yeah and i like to think of 199 00:07:48,869 --> 00:07:47,039 the ice at the poles as almost like ice 200 00:07:50,629 --> 00:07:48,879 cores here on earth if we can examine 201 00:07:53,270 --> 00:07:50,639 that water ice we can actually look back 202 00:07:56,469 --> 00:07:53,280 into the history of the solar system 203 00:07:58,950 --> 00:07:56,479 uh but also just as important it is a 204 00:07:59,909 --> 00:07:58,960 valuable resource and 205 00:08:02,710 --> 00:07:59,919 as 206 00:08:05,909 --> 00:08:02,720 we probably all know water contains 207 00:08:06,790 --> 00:08:05,919 two hydrogen and an oxygen right atom 208 00:08:10,869 --> 00:08:06,800 and 209 00:08:13,110 --> 00:08:10,879 ingredients that go into rocket fuel 210 00:08:15,189 --> 00:08:13,120 and rather than spending lots of rocket 211 00:08:17,430 --> 00:08:15,199 fuel to bring rocket fuel into space 212 00:08:18,950 --> 00:08:17,440 which is what we do now right it'd be 213 00:08:21,749 --> 00:08:18,960 great if we could actually find a 214 00:08:23,990 --> 00:08:21,759 resource and produce rocket fuel outside 215 00:08:25,670 --> 00:08:24,000 the gravity well of earth that would not 216 00:08:27,350 --> 00:08:25,680 only make things more affordable it's 217 00:08:29,909 --> 00:08:27,360 actually could be enabling of new 218 00:08:32,310 --> 00:08:29,919 architectures uh for exploring mars and 219 00:08:35,350 --> 00:08:32,320 beyond yeah well and then 220 00:08:37,269 --> 00:08:35,360 the oxygen in itself is what we breathe 221 00:08:39,670 --> 00:08:37,279 yeah of course yeah and 222 00:08:41,430 --> 00:08:39,680 the the techniques and the approach to 223 00:08:43,029 --> 00:08:41,440 how we excavate 224 00:08:46,150 --> 00:08:43,039 water on the moon 225 00:08:49,190 --> 00:08:46,160 is applicable to even doing it on mars 226 00:08:51,750 --> 00:08:49,200 so if you're looking for long-term 227 00:08:54,550 --> 00:08:51,760 human presence on other worlds and truly 228 00:08:56,389 --> 00:08:54,560 becoming interplanetary species 229 00:08:58,070 --> 00:08:56,399 we can be creating the oxygen that we 230 00:09:00,630 --> 00:08:58,080 breathe and the habitats in which we're 231 00:09:02,070 --> 00:09:00,640 living in off world wow 232 00:09:04,389 --> 00:09:02,080 that's so amazing that we're actually 233 00:09:08,550 --> 00:09:04,399 talking about that you know as a future 234 00:09:12,790 --> 00:09:10,150 i actually have a couple of shout outs 235 00:09:14,710 --> 00:09:12,800 so super snail says that the earth and 236 00:09:17,190 --> 00:09:14,720 moon shirt is awesome 237 00:09:19,190 --> 00:09:17,200 and also uh 238 00:09:20,350 --> 00:09:19,200 said it's great to see tony and kimberly 239 00:09:24,630 --> 00:09:20,360 again 240 00:09:27,829 --> 00:09:24,640 [Music] 241 00:09:30,550 --> 00:09:27,839 outstanding wow all right 242 00:09:31,590 --> 00:09:30,560 do you have any questions yet danielle 243 00:09:32,790 --> 00:09:31,600 i do 244 00:09:33,670 --> 00:09:32,800 um so 245 00:09:34,389 --> 00:09:33,680 moon 246 00:09:36,550 --> 00:09:34,399 uh 247 00:09:39,350 --> 00:09:36,560 momestrites wants to know like what's 248 00:09:40,470 --> 00:09:39,360 the end long-term goal of the artemis 249 00:09:42,790 --> 00:09:40,480 mission 250 00:09:44,310 --> 00:09:42,800 because we've been talking it up but 251 00:09:45,190 --> 00:09:44,320 yeah that's a great question you wanna 252 00:09:47,750 --> 00:09:45,200 yeah 253 00:09:50,630 --> 00:09:47,760 so artemis is a term to describe in a 254 00:09:52,630 --> 00:09:50,640 whole series of missions to the lunar 255 00:09:55,030 --> 00:09:52,640 surface and using 256 00:09:56,790 --> 00:09:55,040 an orbital uh tugboat interplanetary 257 00:09:58,630 --> 00:09:56,800 spaceship called the gateway it's a big 258 00:10:00,870 --> 00:09:58,640 architecture but in the long term 259 00:10:03,030 --> 00:10:00,880 opening it up with many partners along 260 00:10:07,030 --> 00:10:03,040 on this journey we have a sustainable 261 00:10:08,790 --> 00:10:07,040 presence on the moon where we are 262 00:10:10,870 --> 00:10:08,800 you know providing the infrastructure 263 00:10:13,430 --> 00:10:10,880 for us to stay there 264 00:10:15,670 --> 00:10:13,440 for building materials to creating the 265 00:10:17,590 --> 00:10:15,680 rocket fuel to 266 00:10:20,470 --> 00:10:17,600 exploring areas that we've never been 267 00:10:22,230 --> 00:10:20,480 before the you know actually going into 268 00:10:24,310 --> 00:10:22,240 the the depths of craters that we 269 00:10:26,550 --> 00:10:24,320 haven't explored yet um and pieces of 270 00:10:28,470 --> 00:10:26,560 moon we don't see so that long-term 271 00:10:30,069 --> 00:10:28,480 presence on the moon but while we're 272 00:10:32,230 --> 00:10:30,079 using those techniques those become 273 00:10:34,710 --> 00:10:32,240 applicable for to that next step you 274 00:10:35,590 --> 00:10:34,720 know we're living off earth on another 275 00:10:37,910 --> 00:10:35,600 world 276 00:10:39,590 --> 00:10:37,920 in a harsh environment and learning to 277 00:10:41,590 --> 00:10:39,600 deal with those challenges and solving 278 00:10:43,910 --> 00:10:41,600 those challenges and once we've got that 279 00:10:45,590 --> 00:10:43,920 under our belt and we've understood our 280 00:10:46,949 --> 00:10:45,600 neighborhood background 281 00:10:49,269 --> 00:10:46,959 our backyard 282 00:10:51,590 --> 00:10:49,279 we can take that easily to mars yeah so 283 00:10:52,949 --> 00:10:51,600 cool i see lots of other great questions 284 00:10:55,190 --> 00:10:52,959 but i know that some of them are going 285 00:10:57,910 --> 00:10:55,200 to answer yes in the next few minutes so 286 00:10:59,990 --> 00:10:57,920 let's keep going i just want to touch 287 00:11:02,069 --> 00:11:00,000 back on the water a little bit how much 288 00:11:04,069 --> 00:11:02,079 are we actually talking about i know you 289 00:11:08,150 --> 00:11:04,079 two have worked together on a past 290 00:11:10,069 --> 00:11:08,160 mission that found some water 291 00:11:11,509 --> 00:11:10,079 tell us a little bit about that launched 292 00:11:13,400 --> 00:11:11,519 ten years ago 293 00:11:17,509 --> 00:11:13,410 yesterday yesterday 294 00:11:19,990 --> 00:11:17,519 [Music] 295 00:11:22,230 --> 00:11:20,000 and and the mission we launched with lro 296 00:11:24,389 --> 00:11:22,240 the lunar reconnaissance orbiter is 297 00:11:25,829 --> 00:11:24,399 still in orbit around the moon 298 00:11:27,670 --> 00:11:25,839 still collecting data 299 00:11:29,190 --> 00:11:27,680 and making fantastic maps of the lunar 300 00:11:31,350 --> 00:11:29,200 surface which actually was really 301 00:11:32,310 --> 00:11:31,360 enabling of artemis it's what's making 302 00:11:34,710 --> 00:11:32,320 it 303 00:11:37,030 --> 00:11:34,720 able to go forward awesome yeah yeah so 304 00:11:39,269 --> 00:11:37,040 the uh yeah kim and i were both part of 305 00:11:41,110 --> 00:11:39,279 the l cross mission which was 306 00:11:43,269 --> 00:11:41,120 a mission that crashed a spent upper 307 00:11:44,790 --> 00:11:43,279 stage of a rocket into a permanently 308 00:11:47,670 --> 00:11:44,800 shadowed crater at the south pole of the 309 00:11:50,470 --> 00:11:47,680 moon and the purpose was to understand 310 00:11:52,629 --> 00:11:50,480 the nature of hydrogen we had measured 311 00:11:54,470 --> 00:11:52,639 there prior with a different mission 312 00:11:56,470 --> 00:11:54,480 and saw an excess of this hydrogen we 313 00:11:58,470 --> 00:11:56,480 didn't know if the hydrogen was water or 314 00:12:00,710 --> 00:11:58,480 just soil protons which is hydrogen 315 00:12:03,350 --> 00:12:00,720 atoms it's trapped in the soil or what 316 00:12:05,350 --> 00:12:03,360 and and our job was to actually uh 317 00:12:07,430 --> 00:12:05,360 understand it to see if it could 318 00:12:08,949 --> 00:12:07,440 potentially be a resource so it was a 319 00:12:10,870 --> 00:12:08,959 very targeted 320 00:12:12,310 --> 00:12:10,880 mission see what that water 321 00:12:14,790 --> 00:12:12,320 i actually want to back up a little bit 322 00:12:16,550 --> 00:12:14,800 like what is a permanently shattered 323 00:12:18,629 --> 00:12:16,560 crater 324 00:12:21,110 --> 00:12:18,639 good question 325 00:12:23,910 --> 00:12:21,120 doesn't everybody know 326 00:12:26,069 --> 00:12:23,920 well with the tilt of the moon and the 327 00:12:27,829 --> 00:12:26,079 illumination of the sun 328 00:12:30,150 --> 00:12:27,839 there are places at both poles of the 329 00:12:32,150 --> 00:12:30,160 moon where the extreme topography the 330 00:12:33,990 --> 00:12:32,160 rims of the craters of the moon 331 00:12:37,030 --> 00:12:34,000 the sun didn't does not get above those 332 00:12:38,790 --> 00:12:37,040 rims so the basins of those craters are 333 00:12:40,790 --> 00:12:38,800 in permanent shadow and they have been 334 00:12:42,470 --> 00:12:40,800 in permanent shadow for you know four 335 00:12:44,710 --> 00:12:42,480 billion years wow 336 00:12:46,870 --> 00:12:44,720 and being in the shadows if you remember 337 00:12:48,949 --> 00:12:46,880 if you're out in a hot day 338 00:12:50,790 --> 00:12:48,959 and you go underneath the shadow of a 339 00:12:52,949 --> 00:12:50,800 tree you'll notice that things get a 340 00:12:54,710 --> 00:12:52,959 little cooler well and if you're in a 341 00:12:56,710 --> 00:12:54,720 permanently shadowed place on the moon 342 00:12:59,430 --> 00:12:56,720 things get really really cold 343 00:13:01,430 --> 00:12:59,440 so um these these what was interesting 344 00:13:03,269 --> 00:13:01,440 about tony was mentioning this orbiter 345 00:13:05,350 --> 00:13:03,279 mission that had found hydrogen it was 346 00:13:07,110 --> 00:13:05,360 concentrated at the poles 347 00:13:08,629 --> 00:13:07,120 and there was a correlation with the 348 00:13:09,829 --> 00:13:08,639 permanently shadowed craters so there 349 00:13:11,509 --> 00:13:09,839 was this 350 00:13:13,509 --> 00:13:11,519 connection between lots amounts of 351 00:13:16,310 --> 00:13:13,519 hydrogen in very cold places that had 352 00:13:17,670 --> 00:13:16,320 never seen sunlight okay and actually it 353 00:13:19,990 --> 00:13:17,680 was 354 00:13:22,870 --> 00:13:20,000 theorized that these craters would have 355 00:13:25,750 --> 00:13:22,880 cold bottoms and could hold water as 356 00:13:27,350 --> 00:13:25,760 early as 1961. oh really first we're 357 00:13:30,230 --> 00:13:27,360 really understanding the topography even 358 00:13:33,269 --> 00:13:30,240 before the apollo program really got 359 00:13:35,269 --> 00:13:33,279 you know off and running wow and so uh 360 00:13:37,509 --> 00:13:35,279 it wasn't though until 361 00:13:39,350 --> 00:13:37,519 10 years ago uh we 362 00:13:41,910 --> 00:13:39,360 verified the form of that hydrogen in 363 00:13:44,150 --> 00:13:41,920 one of these cold craters as water ice 364 00:13:46,550 --> 00:13:44,160 so let's review now that was l cross 365 00:13:48,470 --> 00:13:46,560 which is the loon 366 00:13:50,470 --> 00:13:48,480 crater observation and sensing 367 00:13:52,629 --> 00:13:50,480 satellites yes okay all right okay and 368 00:13:54,310 --> 00:13:52,639 we we hit a crater at the lunar south 369 00:13:56,310 --> 00:13:54,320 pole and that's why south poles is 370 00:13:58,069 --> 00:13:56,320 tony's favorite right right okay and 371 00:14:00,949 --> 00:13:58,079 where the future astronauts will be 372 00:14:03,509 --> 00:14:00,959 landing exactly okay and do you remember 373 00:14:05,590 --> 00:14:03,519 how much water l cross saw yeah so it 374 00:14:09,189 --> 00:14:05,600 was just like a point measurement right 375 00:14:12,069 --> 00:14:09,199 it made a crater about 35 meters across 376 00:14:14,230 --> 00:14:12,079 um half a football field or so across 377 00:14:17,269 --> 00:14:14,240 and so yeah pretty big hole but you'll 378 00:14:21,910 --> 00:14:17,279 never see it in the dark yeah 379 00:14:25,910 --> 00:14:23,430 but uh 380 00:14:27,829 --> 00:14:25,920 it brought ejecta up into sunlight so we 381 00:14:29,990 --> 00:14:27,839 could examine it and it 382 00:14:31,750 --> 00:14:30,000 threw the soil up the soil 383 00:14:33,350 --> 00:14:31,760 out of shadow until eventually reaches 384 00:14:35,910 --> 00:14:33,360 sunlight and what's i always like to 385 00:14:37,430 --> 00:14:35,920 think about that that's that soil hadn't 386 00:14:39,030 --> 00:14:37,440 seen sunlight in billions of years 387 00:14:41,350 --> 00:14:39,040 that's crazy yeah 388 00:14:43,670 --> 00:14:41,360 and in just the dirt we threw up into 389 00:14:47,590 --> 00:14:43,680 the cloud or into the sun sorry we saw 390 00:14:48,550 --> 00:14:47,600 about 152 gallons of water okay okay and 391 00:14:49,430 --> 00:14:48,560 if you 392 00:14:51,189 --> 00:14:49,440 uh 393 00:14:52,710 --> 00:14:51,199 take all if you take that measurement 394 00:14:55,189 --> 00:14:52,720 and all the other measurements we have 395 00:14:57,910 --> 00:14:55,199 of hydrogen at the poles 396 00:15:00,069 --> 00:14:57,920 and uh make some assumptions about how 397 00:15:03,509 --> 00:15:00,079 it's distributed with depth we're 398 00:15:05,110 --> 00:15:03,519 talking 10 million uh potentially up to 399 00:15:08,230 --> 00:15:05,120 100 million 400 00:15:10,790 --> 00:15:08,240 tons metric tons oh wow of water ice a 401 00:15:12,629 --> 00:15:10,800 lot of water ice it's a lot i think so 402 00:15:14,470 --> 00:15:12,639 it would make a big ice cube i think kim 403 00:15:17,030 --> 00:15:14,480 and i were talking beforehand and it was 404 00:15:20,150 --> 00:15:17,040 about a hundred and thirty 130 meters 405 00:15:23,990 --> 00:15:20,160 130 meter on the side ice cube 406 00:15:25,509 --> 00:15:24,000 stadium for the football stadium 407 00:15:28,310 --> 00:15:25,519 yeah 408 00:15:30,790 --> 00:15:28,320 important science there 409 00:15:32,629 --> 00:15:30,800 the moon's ice cube and yeah to be clear 410 00:15:35,189 --> 00:15:32,639 none of this is flowing liquid water 411 00:15:38,150 --> 00:15:35,199 this is crystals 412 00:15:38,870 --> 00:15:38,160 the temperatures are about minus 200 and 413 00:15:42,550 --> 00:15:38,880 uh 414 00:15:44,470 --> 00:15:42,560 to minus 240 or so below zero centigrade 415 00:15:46,310 --> 00:15:44,480 okay and this was the first time we ever 416 00:15:48,470 --> 00:15:46,320 sampled the bottom of a permanently 417 00:15:50,470 --> 00:15:48,480 shadowed crater i mean since then this 418 00:15:53,030 --> 00:15:50,480 has experiment has been repeated okay 419 00:15:54,389 --> 00:15:53,040 and um in not only did we find water but 420 00:15:56,710 --> 00:15:54,399 there was a bunch of other things that 421 00:15:59,110 --> 00:15:56,720 were excavated as well 422 00:16:02,150 --> 00:15:59,120 gold mercury argon 423 00:16:04,310 --> 00:16:02,160 carbon monoxide and so it's opening up 424 00:16:06,150 --> 00:16:04,320 these questions um when we're going to 425 00:16:08,230 --> 00:16:06,160 have humans and robots going to the 426 00:16:10,949 --> 00:16:08,240 poles of the south pole the moon we're 427 00:16:13,509 --> 00:16:10,959 gonna get the boots on ground the wheels 428 00:16:15,269 --> 00:16:13,519 on ground and really understand what's 429 00:16:17,110 --> 00:16:15,279 there because we've never been there 430 00:16:19,189 --> 00:16:17,120 before we just have this you know simple 431 00:16:20,550 --> 00:16:19,199 impactor experiment that opened more 432 00:16:22,150 --> 00:16:20,560 questions than it answered but it 433 00:16:23,670 --> 00:16:22,160 answered one particular one right the 434 00:16:26,710 --> 00:16:23,680 hydrogen is definitely in the form of 435 00:16:29,269 --> 00:16:26,720 water ice and enough such that there is 436 00:16:31,430 --> 00:16:29,279 the resources to enable the exploration 437 00:16:33,269 --> 00:16:31,440 exciting yeah another good way to put in 438 00:16:35,749 --> 00:16:33,279 perspective is el cross about five 439 00:16:37,749 --> 00:16:35,759 percent by weight water water in the 440 00:16:39,670 --> 00:16:37,759 regolith in the dirt regulators lunar 441 00:16:42,069 --> 00:16:39,680 dirt for comparison that's about what 442 00:16:43,749 --> 00:16:42,079 you have in the sahara yeah oh okay 443 00:16:45,430 --> 00:16:43,759 let's give you some the wettest places 444 00:16:51,030 --> 00:16:45,440 on the moon is as wet as the driest 445 00:16:54,150 --> 00:16:52,470 that's the engineering challenge ahead 446 00:16:55,749 --> 00:16:54,160 that we will solve to excavate it 447 00:16:57,990 --> 00:16:55,759 because we know it's there and we can 448 00:17:00,069 --> 00:16:58,000 extract um you know water has been 449 00:17:02,389 --> 00:17:00,079 extracted from very dry places okay yes 450 00:17:05,829 --> 00:17:02,399 yeah that can be done it can and we will 451 00:17:07,909 --> 00:17:05,839 do it how exciting awesome so 452 00:17:09,270 --> 00:17:07,919 i want to know then what's next okay we 453 00:17:10,789 --> 00:17:09,280 know that people will we'll get there 454 00:17:13,189 --> 00:17:10,799 we're going to send people there let's 455 00:17:15,510 --> 00:17:13,199 talk about how so what's the rocket 456 00:17:18,390 --> 00:17:15,520 that's going to take people on the f on 457 00:17:19,590 --> 00:17:18,400 the artemis missions to the moon who 458 00:17:22,390 --> 00:17:19,600 wants to take that 459 00:17:24,150 --> 00:17:22,400 space launch system that's it the sls 460 00:17:27,350 --> 00:17:24,160 yeah we have an animation i think of it 461 00:17:30,830 --> 00:17:27,360 too that's right yes um there it is 462 00:17:33,110 --> 00:17:30,840 largest rocket ever built 463 00:17:35,590 --> 00:17:33,120 um and uh 464 00:17:38,150 --> 00:17:35,600 it's to bring humans not only to the 465 00:17:39,990 --> 00:17:38,160 moon but actually beyond too they're uh 466 00:17:41,750 --> 00:17:40,000 it carries them 467 00:17:44,150 --> 00:17:41,760 in a capsule that's on the very tip of 468 00:17:46,630 --> 00:17:44,160 that that just went past the frame 469 00:17:48,230 --> 00:17:46,640 called the orion capsule very small 470 00:17:50,150 --> 00:17:48,240 capsule up there 471 00:17:52,150 --> 00:17:50,160 but uh that capsule 472 00:17:54,470 --> 00:17:52,160 uh you'll see a little yeah yeah we have 473 00:17:56,710 --> 00:17:54,480 an animation for that after the sls 474 00:17:59,029 --> 00:17:56,720 it is very powerful in fact it um is 475 00:18:02,230 --> 00:17:59,039 designed to take an incredible amount of 476 00:18:04,950 --> 00:18:02,240 material to you know deep space okay um 477 00:18:07,110 --> 00:18:04,960 so it is servicing moon and mars and 478 00:18:09,190 --> 00:18:07,120 also elsewhere i mean it also has 479 00:18:10,630 --> 00:18:09,200 amazing commercial spin-offs as well 480 00:18:12,630 --> 00:18:10,640 because you can actually put up a 481 00:18:15,029 --> 00:18:12,640 replacements of say the gps satellites 482 00:18:16,950 --> 00:18:15,039 in a single sls launch rocket it has a 483 00:18:19,750 --> 00:18:16,960 huge capacity 484 00:18:21,510 --> 00:18:19,760 and it could transform the way we do 485 00:18:24,470 --> 00:18:21,520 other types of things in the agency so 486 00:18:26,870 --> 00:18:24,480 it's one of many uses of a large rocket 487 00:18:29,110 --> 00:18:26,880 that's been you know uh can be utilized 488 00:18:31,350 --> 00:18:29,120 how awesome it's pretty awesome 489 00:18:33,029 --> 00:18:31,360 danielle you jump in whenever you have 490 00:18:34,870 --> 00:18:33,039 to with a question but otherwise we're 491 00:18:37,830 --> 00:18:34,880 going to keep talking about uh so that 492 00:18:41,190 --> 00:18:37,840 was sls the rocket and tony pointed out 493 00:18:42,710 --> 00:18:41,200 the capsule yeah so let's see the orion 494 00:18:45,669 --> 00:18:42,720 capsule animation and tell us a little 495 00:18:46,789 --> 00:18:45,679 bit about so ryan is uh either it is a 496 00:18:48,789 --> 00:18:46,799 the capsule that will bring the 497 00:18:51,190 --> 00:18:48,799 astronauts wherever they're going to go 498 00:18:54,630 --> 00:18:51,200 and and this indeed can go not just to 499 00:18:57,190 --> 00:18:54,640 the moon but also beyond the mars 500 00:18:59,830 --> 00:18:57,200 and after you know a lot of analysis and 501 00:19:00,710 --> 00:18:59,840 study uh it was eventually concluded 502 00:19:03,270 --> 00:19:00,720 that 503 00:19:05,830 --> 00:19:03,280 the the apollo shape the blunt nose 504 00:19:09,430 --> 00:19:05,840 reentry system that paul used is still 505 00:19:11,270 --> 00:19:09,440 the best way to go forward um however 506 00:19:13,029 --> 00:19:11,280 look how roomy if you're looking into 507 00:19:16,230 --> 00:19:13,039 this video how look how roomy this one 508 00:19:17,590 --> 00:19:16,240 is compared to the apollo um 509 00:19:18,950 --> 00:19:17,600 have anyone seen the apollo 11 510 00:19:20,789 --> 00:19:18,960 documentary that's out in the movie 511 00:19:22,230 --> 00:19:20,799 theaters you get a feel for how tight 512 00:19:23,350 --> 00:19:22,240 apollo is 513 00:19:26,230 --> 00:19:23,360 four 514 00:19:28,390 --> 00:19:26,240 and uh it's a lot more powerful in every 515 00:19:32,470 --> 00:19:28,400 single way from uh 516 00:19:35,270 --> 00:19:32,480 information systems guidance uh payload 517 00:19:37,029 --> 00:19:35,280 everything and and and it's meant to be 518 00:19:39,350 --> 00:19:37,039 able to carry humans 519 00:19:42,549 --> 00:19:39,360 longer distance way beyond the moon okay 520 00:19:44,390 --> 00:19:42,559 so uh it is really is apollo on steroids 521 00:19:47,750 --> 00:19:44,400 i like to say yeah that's awesome i love 522 00:19:51,029 --> 00:19:47,760 that it's kept some of the same designs 523 00:19:52,549 --> 00:19:51,039 way to go apollo engineers 524 00:19:53,669 --> 00:19:52,559 they solved some pretty tough challenges 525 00:19:55,830 --> 00:19:53,679 and they made it happen so because we 526 00:19:58,630 --> 00:19:55,840 know we can do this so they actually 527 00:20:00,390 --> 00:19:58,640 have a question from digital don donger 528 00:20:02,870 --> 00:20:00,400 who wants to know um are you using 529 00:20:05,029 --> 00:20:02,880 specifically any apollo era research or 530 00:20:07,830 --> 00:20:05,039 tech on the quest to return back to the 531 00:20:09,190 --> 00:20:07,840 moon well the the shape that i just 532 00:20:10,950 --> 00:20:09,200 mentioned is 533 00:20:13,110 --> 00:20:10,960 really was derived originally through 534 00:20:15,510 --> 00:20:13,120 the apollo program the shape of that 535 00:20:17,510 --> 00:20:15,520 capsule is very critical 536 00:20:19,669 --> 00:20:17,520 to enabling the reentry 537 00:20:22,789 --> 00:20:19,679 and and and this capsule is meant to 538 00:20:25,510 --> 00:20:22,799 reenter parachute and splash down in in 539 00:20:27,510 --> 00:20:25,520 the ocean just like the apollo program 540 00:20:30,390 --> 00:20:27,520 did and speaking of re-entry here at 541 00:20:32,070 --> 00:20:30,400 nasa ames um we developed and tested the 542 00:20:34,710 --> 00:20:32,080 thermal reentry 543 00:20:36,390 --> 00:20:34,720 materials and for the apollo program is 544 00:20:37,669 --> 00:20:36,400 a chemist a chemical compound called 545 00:20:39,029 --> 00:20:37,679 avcoat 546 00:20:40,470 --> 00:20:39,039 and their heat shield the heat shield 547 00:20:42,310 --> 00:20:40,480 for the heat so that re-entry through 548 00:20:44,230 --> 00:20:42,320 the atmosphere and they would ablate so 549 00:20:45,750 --> 00:20:44,240 they would absorb the heat and then you 550 00:20:47,350 --> 00:20:45,760 know protect the capsules with 551 00:20:49,830 --> 00:20:47,360 successfully returned 552 00:20:53,110 --> 00:20:49,840 um to preparation for orion 553 00:20:55,190 --> 00:20:53,120 engineers uh looked at avcote and 554 00:20:57,430 --> 00:20:55,200 modified the chemistry of that and did a 555 00:20:59,590 --> 00:20:57,440 lot of the testing so there's a direct 556 00:21:02,470 --> 00:20:59,600 connection even with the materials that 557 00:21:04,390 --> 00:21:02,480 were used during apollo pretty cool 558 00:21:07,110 --> 00:21:04,400 and just modified for the the the shape 559 00:21:09,669 --> 00:21:07,120 of the capsule but for to and to support 560 00:21:11,350 --> 00:21:09,679 um even re-entry from um further 561 00:21:12,789 --> 00:21:11,360 destinations say you're coming back from 562 00:21:14,830 --> 00:21:12,799 an asteroid or say you're coming back 563 00:21:17,510 --> 00:21:14,840 from mars orbit or something like 564 00:21:21,270 --> 00:21:17,520 that speeds can be hard 565 00:21:23,190 --> 00:21:21,280 so um it's smarter yeah all around i 566 00:21:25,110 --> 00:21:23,200 love that excellent and i i love these 567 00:21:27,909 --> 00:21:25,120 apollo connections but then on the flip 568 00:21:30,630 --> 00:21:27,919 side how is the artemis program 569 00:21:33,029 --> 00:21:30,640 different from apollo 570 00:21:34,870 --> 00:21:33,039 you want to take this no adventure one 571 00:21:38,149 --> 00:21:34,880 an element that we um that i mentioned 572 00:21:39,510 --> 00:21:38,159 briefly sorry about the spoilers is they 573 00:21:41,430 --> 00:21:39,520 is actually 574 00:21:43,350 --> 00:21:41,440 one of the cooler parts of the artemis 575 00:21:46,390 --> 00:21:43,360 program it's this this object called the 576 00:21:47,270 --> 00:21:46,400 gateway okay and the gateway 577 00:21:49,990 --> 00:21:47,280 is 578 00:21:51,270 --> 00:21:50,000 a for our first interplanetary spaceship 579 00:21:53,190 --> 00:21:51,280 and this is something that nasa has 580 00:21:55,830 --> 00:21:53,200 never really built before 581 00:21:57,590 --> 00:21:55,840 and that's why in a sense is exciting i 582 00:22:01,110 --> 00:21:57,600 mean this um 583 00:22:03,590 --> 00:22:01,120 space module sometimes we call spaceship 584 00:22:05,990 --> 00:22:03,600 will be in lunar orbit 585 00:22:08,549 --> 00:22:06,000 and it will provide the way to access 586 00:22:09,750 --> 00:22:08,559 all different parts of the moon 587 00:22:12,630 --> 00:22:09,760 and 588 00:22:13,830 --> 00:22:12,640 it's also going to be crude but not 100 589 00:22:16,070 --> 00:22:13,840 of the time 590 00:22:18,230 --> 00:22:16,080 so it has to be autonomous it'll have a 591 00:22:20,950 --> 00:22:18,240 lot of autonomy in it and it 592 00:22:22,950 --> 00:22:20,960 also would be providing a way to be a 593 00:22:25,590 --> 00:22:22,960 space laboratory so we can put 594 00:22:28,549 --> 00:22:25,600 experiments on board for understanding 595 00:22:31,029 --> 00:22:28,559 biology outside our magnetosphere 596 00:22:33,190 --> 00:22:31,039 it also can dock with all the different 597 00:22:35,270 --> 00:22:33,200 commercial and 598 00:22:37,750 --> 00:22:35,280 international partners it has an open 599 00:22:39,270 --> 00:22:37,760 architecture the port designs are going 600 00:22:41,110 --> 00:22:39,280 to be available for anyone who wants to 601 00:22:43,909 --> 00:22:41,120 build things that connect to it the 602 00:22:45,350 --> 00:22:43,919 apollo will connect apollo orion will 603 00:22:49,669 --> 00:22:45,360 connect to it 604 00:22:51,270 --> 00:22:49,679 service modules but it has the ability 605 00:22:53,350 --> 00:22:51,280 to change its orbit 606 00:22:55,430 --> 00:22:53,360 so it can also become this 607 00:22:57,430 --> 00:22:55,440 interplanetary tugboat because it can 608 00:22:59,590 --> 00:22:57,440 move things around and first enable 609 00:23:01,909 --> 00:22:59,600 travel i mean it's the transportation 610 00:23:03,750 --> 00:23:01,919 backbone for mars exploration oh wow 611 00:23:05,909 --> 00:23:03,760 okay and again this is gateway this is 612 00:23:08,470 --> 00:23:05,919 gateway it's called gateway and we're 613 00:23:09,350 --> 00:23:08,480 going to um this space 614 00:23:11,430 --> 00:23:09,360 ship 615 00:23:13,029 --> 00:23:11,440 um we'll oh and we have an animation 616 00:23:14,870 --> 00:23:13,039 showing of this orbit in which the 617 00:23:16,310 --> 00:23:14,880 gateway for the lunar exploration will 618 00:23:19,029 --> 00:23:16,320 have 619 00:23:21,190 --> 00:23:19,039 really is enabling and this is the part 620 00:23:23,110 --> 00:23:21,200 of the artemis program that's very this 621 00:23:24,870 --> 00:23:23,120 is apollo didn't do this apollo took 622 00:23:25,750 --> 00:23:24,880 everything with them and everything came 623 00:23:28,390 --> 00:23:25,760 back 624 00:23:31,990 --> 00:23:28,400 so um artemis is is building up a 625 00:23:34,230 --> 00:23:32,000 sustainable presence and this uh gateway 626 00:23:36,070 --> 00:23:34,240 is key to that yeah and one one one part 627 00:23:37,590 --> 00:23:36,080 that i'd like to emphasize that kim 628 00:23:40,549 --> 00:23:37,600 mentioned that is really different from 629 00:23:43,590 --> 00:23:40,559 apollo is this open architecture aspect 630 00:23:46,310 --> 00:23:43,600 is nasa's not doing this alone and it's 631 00:23:48,230 --> 00:23:46,320 and it's even beyond what we did for the 632 00:23:49,830 --> 00:23:48,240 international space station where we had 633 00:23:50,789 --> 00:23:49,840 lots of other government agencies 634 00:23:53,110 --> 00:23:50,799 involved 635 00:23:54,630 --> 00:23:53,120 there is a huge involvement from the 636 00:23:57,029 --> 00:23:54,640 private commercial 637 00:23:58,549 --> 00:23:57,039 sector that's involved in all parts of 638 00:24:01,190 --> 00:23:58,559 this so 639 00:24:03,190 --> 00:24:01,200 this artemis program and lunar 640 00:24:05,669 --> 00:24:03,200 exploration going forward 641 00:24:07,350 --> 00:24:05,679 has got a commercial element a private 642 00:24:09,350 --> 00:24:07,360 sector commercial element a lot of 643 00:24:11,830 --> 00:24:09,360 people call it new space 644 00:24:14,710 --> 00:24:11,840 part of it that didn't exist during 645 00:24:18,390 --> 00:24:14,720 apollo so we are really i think 646 00:24:21,830 --> 00:24:18,400 at the you know at the dawn of a new age 647 00:24:22,870 --> 00:24:21,840 of exploration uh and in space beyond 648 00:24:24,230 --> 00:24:22,880 leo 649 00:24:26,149 --> 00:24:24,240 and the low earth orbit lower 650 00:24:28,310 --> 00:24:26,159 authorities are going farther out yeah 651 00:24:29,830 --> 00:24:28,320 and also as tony was saying about this 652 00:24:30,950 --> 00:24:29,840 it's sort of a space economy have a lot 653 00:24:31,909 --> 00:24:30,960 of partners 654 00:24:34,070 --> 00:24:31,919 um 655 00:24:35,590 --> 00:24:34,080 we're on the verge of you know if you 656 00:24:37,190 --> 00:24:35,600 were to go back in time and ask the 657 00:24:38,950 --> 00:24:37,200 wright brothers to look at modern day 658 00:24:40,630 --> 00:24:38,960 today and see that oh i can fly from 659 00:24:42,630 --> 00:24:40,640 place to place on this planet using an 660 00:24:44,390 --> 00:24:42,640 airplane that they did this 661 00:24:46,310 --> 00:24:44,400 or go back and talk to alexander graham 662 00:24:47,830 --> 00:24:46,320 bell invented the telephone and we all 663 00:24:49,110 --> 00:24:47,840 look at using our smartphones to 664 00:24:51,909 --> 00:24:49,120 communicate 665 00:24:54,549 --> 00:24:51,919 we have no clue what the future of space 666 00:24:56,870 --> 00:24:54,559 will be when we involve the commercial 667 00:24:58,789 --> 00:24:56,880 aspect of it wow it is really an 668 00:25:01,510 --> 00:24:58,799 unbounded future 669 00:25:03,669 --> 00:25:01,520 that's monumental yeah i'm excited this 670 00:25:06,310 --> 00:25:03,679 is why it's different than a place right 671 00:25:08,149 --> 00:25:06,320 if you ask a simple question you get a 672 00:25:09,430 --> 00:25:08,159 pretty profound answer yeah from the 673 00:25:10,710 --> 00:25:09,440 science point of view tony and everybody 674 00:25:12,149 --> 00:25:10,720 else excited about the science but it 675 00:25:13,669 --> 00:25:12,159 has a lot of it's much bigger than once 676 00:25:15,029 --> 00:25:13,679 and then it will enable a lot of that 677 00:25:16,630 --> 00:25:15,039 science and we'll be able to do things 678 00:25:19,909 --> 00:25:16,640 we could never have done before before 679 00:25:21,909 --> 00:25:19,919 yeah yeah wow okay how long how long 1 680 00:25:24,390 --> 00:25:21,919 656 days 681 00:25:27,510 --> 00:25:24,400 well let's move into our rapid fire 682 00:25:28,950 --> 00:25:27,520 section so i'm not going to give any 683 00:25:30,470 --> 00:25:28,960 usernames but i'm just going to go ahead 684 00:25:36,310 --> 00:25:30,480 and just 685 00:25:40,870 --> 00:25:37,909 what is the long-term effect of the 686 00:25:42,470 --> 00:25:40,880 human body on the moon 687 00:25:44,070 --> 00:25:42,480 long-term effect of the human body on 688 00:25:45,269 --> 00:25:44,080 the moon or the environment on the human 689 00:25:48,070 --> 00:25:45,279 body 690 00:25:50,070 --> 00:25:48,080 oh i understand the environment so it 691 00:25:51,510 --> 00:25:50,080 goes both ways so and that's actually a 692 00:25:53,590 --> 00:25:51,520 really interesting question from the 693 00:25:55,029 --> 00:25:53,600 science standpoint in particular these 694 00:25:57,350 --> 00:25:55,039 cold areas 695 00:25:59,909 --> 00:25:57,360 these uh in the craters are what are 696 00:26:02,470 --> 00:25:59,919 called cold traps they're so cold any 697 00:26:04,789 --> 00:26:02,480 molecules that get in there freeze out 698 00:26:07,110 --> 00:26:04,799 so every time we've gone to the moon 699 00:26:08,950 --> 00:26:07,120 and the astronauts vented 700 00:26:11,190 --> 00:26:08,960 water or vented other things or 701 00:26:13,269 --> 00:26:11,200 outgassed outcasts mean stuff 702 00:26:15,669 --> 00:26:13,279 subliming off of equipment 703 00:26:17,430 --> 00:26:15,679 those molecules some of those molecules 704 00:26:19,669 --> 00:26:17,440 very likely found their ways to the 705 00:26:21,590 --> 00:26:19,679 poles of the moon and froze out 706 00:26:23,750 --> 00:26:21,600 and they're there now forever until a 707 00:26:27,269 --> 00:26:23,760 meteorite might release them 708 00:26:29,909 --> 00:26:27,279 if we go once we go exploring 709 00:26:31,909 --> 00:26:29,919 not just we nasa but the world 710 00:26:33,750 --> 00:26:31,919 uh we'll bring more and more of these 711 00:26:35,269 --> 00:26:33,760 volatiles and other materials to the 712 00:26:37,350 --> 00:26:35,279 moon that will be trapped in the cold 713 00:26:39,510 --> 00:26:37,360 trap so if you're trying to understand 714 00:26:42,630 --> 00:26:39,520 some pristine environments to understand 715 00:26:44,230 --> 00:26:42,640 the history the last three billion years 716 00:26:45,990 --> 00:26:44,240 you you want to do it in a way that you 717 00:26:47,590 --> 00:26:46,000 can understand what contaminants you've 718 00:26:50,830 --> 00:26:47,600 brought there yourself 719 00:26:53,669 --> 00:26:50,840 and we actually we nasa ames 720 00:26:55,669 --> 00:26:53,679 uh flew a mission not long 721 00:26:57,830 --> 00:26:55,679 long ago called lady the lunar 722 00:26:59,510 --> 00:26:57,840 atmospheric dust environment explorer 723 00:27:01,750 --> 00:26:59,520 and its principal purpose was actually 724 00:27:02,950 --> 00:27:01,760 to understand the lunar atmosphere the 725 00:27:04,870 --> 00:27:02,960 exosphere 726 00:27:06,390 --> 00:27:04,880 in its pristine state with the 727 00:27:08,149 --> 00:27:06,400 anticipation that more and more 728 00:27:10,630 --> 00:27:08,159 countries and commercial peoples would 729 00:27:12,230 --> 00:27:10,640 be going to the moon and so we wanted to 730 00:27:14,630 --> 00:27:12,240 get kind of a background before we 731 00:27:16,950 --> 00:27:14,640 started impacting right yeah yeah the 732 00:27:18,230 --> 00:27:16,960 baseline before we touched it right 733 00:27:19,269 --> 00:27:18,240 right interesting 734 00:27:21,110 --> 00:27:19,279 from a 735 00:27:23,029 --> 00:27:21,120 impact on the human body radiation is 736 00:27:25,110 --> 00:27:23,039 one of the principal concerns 737 00:27:27,029 --> 00:27:25,120 and there's a lot of very clever 738 00:27:28,950 --> 00:27:27,039 solutions being looked at 739 00:27:30,710 --> 00:27:28,960 uh in terms of shielding and and we talk 740 00:27:32,710 --> 00:27:30,720 about water as a resource 741 00:27:34,389 --> 00:27:32,720 there's lots of other resources 742 00:27:35,909 --> 00:27:34,399 at the moon and 743 00:27:36,870 --> 00:27:35,919 especially at the poles including 744 00:27:39,029 --> 00:27:36,880 lighting 745 00:27:41,110 --> 00:27:39,039 for the solar power but also the dirt 746 00:27:44,630 --> 00:27:41,120 itself the regolith can be an excellent 747 00:27:46,070 --> 00:27:44,640 insulator oh okay so uh as kimberly was 748 00:27:47,990 --> 00:27:46,080 talking about living off the land 749 00:27:49,430 --> 00:27:48,000 involves using whatever you have 750 00:27:51,510 --> 00:27:49,440 whatever you have to 751 00:27:53,830 --> 00:27:51,520 make your situation better 752 00:27:55,590 --> 00:27:53,840 yeah excellent okay next question how 753 00:27:56,549 --> 00:27:55,600 many launches until the first base is 754 00:27:58,549 --> 00:27:56,559 set up 755 00:28:09,750 --> 00:27:58,559 um 756 00:28:12,389 --> 00:28:09,760 that's the 2024 milestone and then 757 00:28:14,149 --> 00:28:12,399 there's a later milestone in 2028 where 758 00:28:17,510 --> 00:28:14,159 we have a more established presence 759 00:28:19,190 --> 00:28:17,520 there um prior to um the first humans 760 00:28:21,350 --> 00:28:19,200 going on on the moon we'll have the 761 00:28:23,029 --> 00:28:21,360 first launch of artemis artemis one 762 00:28:25,110 --> 00:28:23,039 which will not have humans on board but 763 00:28:27,029 --> 00:28:25,120 we'll carry uh space satellites and 764 00:28:27,909 --> 00:28:27,039 robots and the like some will go to deep 765 00:28:30,230 --> 00:28:27,919 space 766 00:28:31,909 --> 00:28:30,240 a second artemis mission will actually 767 00:28:34,310 --> 00:28:31,919 go to the moon or in orbit around the 768 00:28:36,710 --> 00:28:34,320 moon it's on that third launch of the 769 00:28:39,269 --> 00:28:36,720 sls um that we would be carrying the 770 00:28:41,990 --> 00:28:39,279 humans and that's the 2024 milestone so 771 00:28:44,470 --> 00:28:42,000 we should see a sequence of incremental 772 00:28:46,630 --> 00:28:44,480 steps towards proving out the new launch 773 00:28:49,110 --> 00:28:46,640 system and the new capabilities in 774 00:28:51,269 --> 00:28:49,120 addition the first module of the gateway 775 00:28:53,350 --> 00:28:51,279 which is the solar propulsion element 776 00:28:55,750 --> 00:28:53,360 which is a really cool technology 777 00:28:58,310 --> 00:28:55,760 advancement we've never seen an engine 778 00:28:59,430 --> 00:28:58,320 like this on a spaceship before that's 779 00:29:01,029 --> 00:28:59,440 going to be launched by a commercial 780 00:29:01,990 --> 00:29:01,039 rocket and so that's you know we're 781 00:29:04,310 --> 00:29:02,000 going to be having all these different 782 00:29:06,230 --> 00:29:04,320 types of infrastructures getting us all 783 00:29:07,430 --> 00:29:06,240 part of the artemis program and that's 784 00:29:08,870 --> 00:29:07,440 it this 785 00:29:09,990 --> 00:29:08,880 really brings an important point it's 786 00:29:11,669 --> 00:29:10,000 not a 787 00:29:14,470 --> 00:29:11,679 it will be done by this date it will be 788 00:29:16,950 --> 00:29:14,480 a continuous development and build up of 789 00:29:17,990 --> 00:29:16,960 in a to reach an eventual sustained 790 00:29:21,110 --> 00:29:18,000 presence 791 00:29:22,870 --> 00:29:21,120 and so the exact date when it becomes a 792 00:29:30,230 --> 00:29:22,880 base or whatever you want to call it 793 00:29:33,750 --> 00:29:31,669 when that exactly happens it's kind of 794 00:29:36,630 --> 00:29:33,760 ill-defined because it's really building 795 00:29:39,590 --> 00:29:36,640 up of capabilities over time 796 00:29:40,950 --> 00:29:39,600 there will be longer and longer stays as 797 00:29:43,669 --> 00:29:40,960 they move through these various phases 798 00:29:46,070 --> 00:29:43,679 as kimberly stayed as mentioned 799 00:29:48,389 --> 00:29:46,080 um for the astronauts on the surface so 800 00:29:49,909 --> 00:29:48,399 okay so we have time for two short 801 00:29:52,149 --> 00:29:49,919 questions i hope 802 00:29:53,430 --> 00:29:52,159 so how long is this gateway going to be 803 00:29:55,350 --> 00:29:53,440 inhabited by astronauts when it's 804 00:29:56,630 --> 00:29:55,360 finished that's a good question i mean 805 00:29:59,669 --> 00:29:56,640 it's variable 806 00:30:01,510 --> 00:29:59,679 um the the key point is that that 807 00:30:02,950 --> 00:30:01,520 spaceship needs to be able to operate 808 00:30:04,870 --> 00:30:02,960 without humans because there will be 809 00:30:07,830 --> 00:30:04,880 prairies in which humans aren't on board 810 00:30:08,950 --> 00:30:07,840 um so don't know the exact fraction of 811 00:30:10,310 --> 00:30:08,960 it but it's going to have two different 812 00:30:12,230 --> 00:30:10,320 modes when the humans are on board and 813 00:30:13,350 --> 00:30:12,240 when they're not yeah i've heard numbers 814 00:30:15,669 --> 00:30:13,360 uh 815 00:30:17,350 --> 00:30:15,679 up to 30 days at a time okay so they're 816 00:30:19,029 --> 00:30:17,360 not going to be up there for a year like 817 00:30:20,470 --> 00:30:19,039 we do on space station they'll go up 818 00:30:22,389 --> 00:30:20,480 there 819 00:30:23,830 --> 00:30:22,399 and then come back in in a month or two 820 00:30:25,669 --> 00:30:23,840 um and so that's to 821 00:30:27,590 --> 00:30:25,679 kimberly's point is a lot of the time 822 00:30:30,950 --> 00:30:27,600 you'll have to have robots running the 823 00:30:32,950 --> 00:30:30,960 house okay so last question 824 00:30:36,630 --> 00:30:32,960 uh someone wants to know like what's the 825 00:30:38,950 --> 00:30:36,640 coolest thing about gateway 826 00:30:43,190 --> 00:30:38,960 i've heard you vote for this power well 827 00:30:47,510 --> 00:30:45,510 i call it the tugboat this is electric 828 00:30:49,510 --> 00:30:47,520 propulsion system 829 00:30:51,909 --> 00:30:49,520 and it's at a power level we've never 830 00:30:53,669 --> 00:30:51,919 built before really and what's neat is 831 00:30:55,269 --> 00:30:53,679 it allows it to change its orbit around 832 00:30:57,350 --> 00:30:55,279 the moon so it is really a spaceship 833 00:31:00,070 --> 00:30:57,360 it's not just going in an orbit it can 834 00:31:01,909 --> 00:31:00,080 actually steer this entire space station 835 00:31:03,029 --> 00:31:01,919 size kind of thing 836 00:31:05,669 --> 00:31:03,039 in space 837 00:31:07,269 --> 00:31:05,679 and and then ultimately it's it's the 838 00:31:10,070 --> 00:31:07,279 kind of engine that's going to be used 839 00:31:12,789 --> 00:31:10,080 to bring us to mars and asteroids into 840 00:31:13,909 --> 00:31:12,799 wherever else so okay and now it's a 841 00:31:15,029 --> 00:31:13,919 slow 842 00:31:16,789 --> 00:31:15,039 ride 843 00:31:18,789 --> 00:31:16,799 slow acceleration 844 00:31:20,230 --> 00:31:18,799 acceleration it 845 00:31:21,830 --> 00:31:20,240 is slow but 846 00:31:23,669 --> 00:31:21,840 it's powerful it allows you to get to 847 00:31:25,350 --> 00:31:23,679 the kinds of velocities with a lot of 848 00:31:27,110 --> 00:31:25,360 mass that you need to to do 849 00:31:30,230 --> 00:31:27,120 interplanetary travel okay and i like 850 00:31:31,830 --> 00:31:30,240 the open architecture i don't think 851 00:31:34,789 --> 00:31:31,840 all the engineers have figured out all 852 00:31:36,149 --> 00:31:34,799 the wonderful uses of gateway 853 00:31:37,669 --> 00:31:36,159 because it's a little i mean it's going 854 00:31:39,430 --> 00:31:37,679 to be designed for a certain purpose and 855 00:31:41,669 --> 00:31:39,440 will achieve those purposes 856 00:31:43,669 --> 00:31:41,679 allowing the docking of multiple 857 00:31:44,870 --> 00:31:43,679 vehicles from different countries and 858 00:31:46,549 --> 00:31:44,880 companies 859 00:31:48,310 --> 00:31:46,559 allowing astronauts to stay for periods 860 00:31:49,990 --> 00:31:48,320 of days months 861 00:31:51,909 --> 00:31:50,000 being in constant communication with the 862 00:31:53,750 --> 00:31:51,919 earth being in communication with the 863 00:31:55,269 --> 00:31:53,760 surface of the moon being able to 864 00:31:57,669 --> 00:31:55,279 deliver things to the surface of the 865 00:31:59,430 --> 00:31:57,679 moon at different latitudes i mean it's 866 00:32:01,669 --> 00:31:59,440 very versatile 867 00:32:03,990 --> 00:32:01,679 but it could also be a test bed for 868 00:32:06,630 --> 00:32:04,000 testing um other types of vehicles that 869 00:32:08,389 --> 00:32:06,640 actually might be made in space someday 870 00:32:11,430 --> 00:32:08,399 and then launch them from there i mean 871 00:32:14,630 --> 00:32:11,440 it has a lifetime that will keep giving 872 00:32:17,590 --> 00:32:14,640 we're only thinking about how to uh you 873 00:32:19,430 --> 00:32:17,600 know do that first step is the the first 874 00:32:21,750 --> 00:32:19,440 step in the return to the moon the 875 00:32:23,350 --> 00:32:21,760 forward to the moon part um 876 00:32:26,389 --> 00:32:23,360 but there's a lot more than it can give 877 00:32:27,990 --> 00:32:26,399 okay yeah you you both keep mentioning 878 00:32:29,830 --> 00:32:28,000 learning at the moon and then we'll go 879 00:32:31,590 --> 00:32:29,840 on and you know sls could take us to 880 00:32:34,149 --> 00:32:31,600 mars let's talk really quickly a little 881 00:32:36,070 --> 00:32:34,159 bit about mars so what are some favorite 882 00:32:38,310 --> 00:32:36,080 fun facts about mars that you can share 883 00:32:40,630 --> 00:32:38,320 with us okay well we have a picture of 884 00:32:41,590 --> 00:32:40,640 mars to cue people and what mars looks 885 00:32:43,430 --> 00:32:41,600 like 886 00:32:44,710 --> 00:32:43,440 it's um it's the fourth planet around 887 00:32:47,430 --> 00:32:44,720 the sun 888 00:32:49,669 --> 00:32:47,440 it's a red planet the red is um 889 00:32:52,710 --> 00:32:49,679 primarily due to iron in the um the 890 00:32:53,909 --> 00:32:52,720 rocks on the surface of mars 891 00:32:56,230 --> 00:32:53,919 mars 892 00:32:58,310 --> 00:32:56,240 has polar caps it has you know it's one 893 00:33:00,870 --> 00:32:58,320 of the other bodies besides the earth 894 00:33:03,190 --> 00:33:00,880 that has um frozen 895 00:33:05,350 --> 00:33:03,200 um ice it's water ice and carbon dioxide 896 00:33:07,669 --> 00:33:05,360 ice at the polar poles 897 00:33:09,430 --> 00:33:07,679 um it's uh 898 00:33:10,789 --> 00:33:09,440 it has an atmosphere 899 00:33:12,549 --> 00:33:10,799 but its atmosphere is different than 900 00:33:13,990 --> 00:33:12,559 earth's um it's probably made of carbon 901 00:33:15,590 --> 00:33:14,000 dioxide whereas our atmosphere is 902 00:33:17,590 --> 00:33:15,600 nitrogen based 903 00:33:19,430 --> 00:33:17,600 um and uh 904 00:33:21,110 --> 00:33:19,440 if you it's the for where the earth is 905 00:33:22,830 --> 00:33:21,120 the third planet and mars is the fourth 906 00:33:26,070 --> 00:33:22,840 planet we're both circling around the 907 00:33:27,909 --> 00:33:26,080 sun um if you imagine racetrack cars on 908 00:33:30,630 --> 00:33:27,919 a racetrack um 909 00:33:33,110 --> 00:33:30,640 so at our closest distance between the 910 00:33:35,669 --> 00:33:33,120 earth and mars is about 34 million miles 911 00:33:37,909 --> 00:33:35,679 and that happens every 26 months 912 00:33:40,389 --> 00:33:37,919 otherwise we're doing laps um right 913 00:33:42,070 --> 00:33:40,399 there we're moving at different speeds 914 00:33:44,389 --> 00:33:42,080 around the racetrack yeah so this is a 915 00:33:47,029 --> 00:33:44,399 reason why when we launch our you know 916 00:33:49,590 --> 00:33:47,039 robots to mars and in the future the 917 00:33:52,870 --> 00:33:49,600 human the crude missions to mars uh 918 00:33:56,230 --> 00:33:52,880 taking advantage of the close that 26 919 00:33:57,909 --> 00:33:56,240 month period of uh of alignment okay 920 00:34:00,230 --> 00:33:57,919 help shorten the distance because even 921 00:34:02,470 --> 00:34:00,240 at that shortest distance the trip is 922 00:34:03,909 --> 00:34:02,480 still about six to nine months yeah okay 923 00:34:06,789 --> 00:34:03,919 still a long way do you want to take 924 00:34:09,030 --> 00:34:06,799 advantage of that yeah excellent all 925 00:34:11,109 --> 00:34:09,040 right and the moon you say is going to 926 00:34:13,750 --> 00:34:11,119 help us practice for what we might do 927 00:34:16,310 --> 00:34:13,760 when we reach everything 928 00:34:18,790 --> 00:34:16,320 so much of what we will be doing on 929 00:34:21,190 --> 00:34:18,800 the moon is extensible 930 00:34:22,950 --> 00:34:21,200 to to mars and and everything from the 931 00:34:25,030 --> 00:34:22,960 kinds of tools we use 932 00:34:26,790 --> 00:34:25,040 to the procedures and processes and the 933 00:34:29,430 --> 00:34:26,800 technologies 934 00:34:32,069 --> 00:34:29,440 learning to uh really work 935 00:34:34,149 --> 00:34:32,079 and and build and construct and uh 936 00:34:36,710 --> 00:34:34,159 different environments that the moon and 937 00:34:39,190 --> 00:34:36,720 mars everything from gravity to low 938 00:34:41,589 --> 00:34:39,200 little to no atmosphere etc 939 00:34:44,389 --> 00:34:41,599 um is really important and and bring it 940 00:34:45,829 --> 00:34:44,399 back to water as kimberly mentioned mars 941 00:34:47,589 --> 00:34:45,839 has got water we've known that for a 942 00:34:49,190 --> 00:34:47,599 while it's got a lot more water than the 943 00:34:50,069 --> 00:34:49,200 moon 944 00:34:51,750 --> 00:34:50,079 and 945 00:34:54,069 --> 00:34:51,760 but that is the one of the key 946 00:34:56,310 --> 00:34:54,079 connections between the moon and mars is 947 00:34:59,349 --> 00:34:56,320 as we learn to utilize 948 00:35:00,790 --> 00:34:59,359 water on the moon everything from 949 00:35:03,190 --> 00:35:00,800 locating it 950 00:35:03,910 --> 00:35:03,200 excavating it processing it all that can 951 00:35:06,150 --> 00:35:03,920 be 952 00:35:08,390 --> 00:35:06,160 carried over and applied to how we do 953 00:35:09,510 --> 00:35:08,400 that on mars which we want to do we want 954 00:35:15,829 --> 00:35:09,520 to 955 00:35:18,390 --> 00:35:15,839 eventually we will of course the first 956 00:35:20,710 --> 00:35:18,400 few times but you can't it's too far 957 00:35:22,870 --> 00:35:20,720 away yeah all right let's just say i was 958 00:35:25,270 --> 00:35:22,880 mentioning earlier is once we're really 959 00:35:27,430 --> 00:35:25,280 comfortable with this whole approach on 960 00:35:29,510 --> 00:35:27,440 excavating the water and processing the 961 00:35:32,390 --> 00:35:29,520 water and transferring it to rocket fuel 962 00:35:34,390 --> 00:35:32,400 or oxygen or other utilizations because 963 00:35:37,190 --> 00:35:34,400 water can be used in many different ways 964 00:35:38,550 --> 00:35:37,200 um that's a totally applicable system 965 00:35:40,470 --> 00:35:38,560 for mars 966 00:35:42,550 --> 00:35:40,480 um you know directly 967 00:35:44,630 --> 00:35:42,560 and also though most likely there will 968 00:35:46,230 --> 00:35:44,640 be wonderful spin-offs that can be used 969 00:35:47,750 --> 00:35:46,240 back here on earth oh yeah i mean 970 00:35:50,790 --> 00:35:47,760 anything to do with things in a closed 971 00:35:52,150 --> 00:35:50,800 system is uh usually very power 972 00:35:54,069 --> 00:35:52,160 conscious you're not using a lot of 973 00:35:56,069 --> 00:35:54,079 energy 974 00:35:57,829 --> 00:35:56,079 recycling a lot of things 975 00:36:00,150 --> 00:35:57,839 will have you know very improved 976 00:36:01,750 --> 00:36:00,160 technology uh who knows what we're doing 977 00:36:03,910 --> 00:36:01,760 actually i have a question from the chat 978 00:36:05,430 --> 00:36:03,920 looks like king goldboygamer wants to 979 00:36:08,950 --> 00:36:05,440 know like when are we actually going to 980 00:36:15,349 --> 00:36:09,670 i 981 00:36:18,550 --> 00:36:15,359 the top of my head 982 00:36:21,030 --> 00:36:18,560 but it would be uh 983 00:36:22,470 --> 00:36:21,040 you know a couple decades 984 00:36:24,069 --> 00:36:22,480 it's still a little ways out so first 985 00:36:25,510 --> 00:36:24,079 we're going to the moon we're going to 986 00:36:27,910 --> 00:36:25,520 practice we're going to learn to 987 00:36:28,950 --> 00:36:27,920 excavate water and process it and all 988 00:36:31,670 --> 00:36:28,960 that 989 00:36:33,349 --> 00:36:31,680 and also um the most fragile part in 990 00:36:35,270 --> 00:36:33,359 this whole uh 991 00:36:38,230 --> 00:36:35,280 amazing exploration adventure is the 992 00:36:40,150 --> 00:36:38,240 human body wow the human body outside 993 00:36:43,190 --> 00:36:40,160 the magnetosphere you know we've had 994 00:36:45,030 --> 00:36:43,200 only um 24 individuals who've been 995 00:36:47,430 --> 00:36:45,040 outside that we are now going to have 996 00:36:49,510 --> 00:36:47,440 the ability to really study biology and 997 00:36:51,829 --> 00:36:49,520 how the human body is reacting this this 998 00:36:53,270 --> 00:36:51,839 will make us totally prepared for that 999 00:36:54,870 --> 00:36:53,280 long trip to mars 1000 00:36:57,270 --> 00:36:54,880 because a mission to the moon is three 1001 00:36:59,990 --> 00:36:57,280 days and you're on the surface for weeks 1002 00:37:00,950 --> 00:37:00,000 months come back but you're you're close 1003 00:37:02,390 --> 00:37:00,960 to home 1004 00:37:04,790 --> 00:37:02,400 when you go to mars we're talking a 1005 00:37:06,310 --> 00:37:04,800 two-year and how is the bot you know 1006 00:37:07,349 --> 00:37:06,320 it's like a six months nine months to 1007 00:37:08,470 --> 00:37:07,359 get there you're gonna be there for a 1008 00:37:10,950 --> 00:37:08,480 few months you come back you want to 1009 00:37:12,310 --> 00:37:10,960 take advantage of the sure close by so 1010 00:37:14,150 --> 00:37:12,320 you're going to be on a sort of a 1011 00:37:16,790 --> 00:37:14,160 two-year time scale right 1012 00:37:18,870 --> 00:37:16,800 just think about it um you know 1013 00:37:20,950 --> 00:37:18,880 what we're going to learn to protect the 1014 00:37:23,670 --> 00:37:20,960 human body 1015 00:37:24,950 --> 00:37:23,680 and uh you know enable 1016 00:37:27,109 --> 00:37:24,960 all the infrastructure to allow the 1017 00:37:29,349 --> 00:37:27,119 human body to survive and thrive we'll 1018 00:37:30,069 --> 00:37:29,359 solve that by being on the moon yeah 1019 00:37:33,030 --> 00:37:30,079 cool 1020 00:37:34,950 --> 00:37:33,040 so tell me quickly so so i want to know 1021 00:37:37,030 --> 00:37:34,960 what's coming up then you know 1022 00:37:39,829 --> 00:37:37,040 what's what's in the news coming up next 1023 00:37:41,430 --> 00:37:39,839 in the process so um human landers will 1024 00:37:44,390 --> 00:37:41,440 be built 1025 00:37:46,470 --> 00:37:44,400 uh by by nasa by partners what do you 1026 00:37:47,829 --> 00:37:46,480 guys know about that 1027 00:37:49,109 --> 00:37:47,839 there was a i believe there was a bid 1028 00:37:52,310 --> 00:37:49,119 that went out on the street for 1029 00:37:54,310 --> 00:37:52,320 companies to um provide lunar landers um 1030 00:37:56,069 --> 00:37:54,320 and docking with the gateway or not 1031 00:37:58,870 --> 00:37:56,079 because it's an open it's a different 1032 00:38:01,510 --> 00:37:58,880 type of architecture you can use um but 1033 00:38:03,270 --> 00:38:01,520 yeah okay yeah there's and there's a 1034 00:38:05,589 --> 00:38:03,280 variety of landers being 1035 00:38:06,630 --> 00:38:05,599 pursued with the commercial sector with 1036 00:38:09,670 --> 00:38:06,640 nasa 1037 00:38:13,349 --> 00:38:09,680 and there are smaller landers 1038 00:38:16,550 --> 00:38:13,359 being built now and we've actually 1039 00:38:18,790 --> 00:38:16,560 nasa just recently selected three to be 1040 00:38:20,630 --> 00:38:18,800 carrying nasa payloads 1041 00:38:22,390 --> 00:38:20,640 so instruments and things before the 1042 00:38:24,710 --> 00:38:22,400 people go exactly it would land next 1043 00:38:27,829 --> 00:38:24,720 year next year already as soon as next 1044 00:38:31,430 --> 00:38:27,839 year and and a couple in in the summer 1045 00:38:32,550 --> 00:38:31,440 21 july 2021 and what's really neat is 1046 00:38:35,589 --> 00:38:32,560 these these 1047 00:38:37,349 --> 00:38:35,599 um companies are providing nasa a 1048 00:38:39,510 --> 00:38:37,359 delivery surface 1049 00:38:41,270 --> 00:38:39,520 it's not nasa telling them we need a 1050 00:38:43,510 --> 00:38:41,280 lander like this 1051 00:38:45,190 --> 00:38:43,520 no it's they're building a lander that 1052 00:38:48,069 --> 00:38:45,200 provides a service 1053 00:38:50,310 --> 00:38:48,079 and selling that service then okay nasa 1054 00:38:52,710 --> 00:38:50,320 here's an example of one on the screen 1055 00:38:55,030 --> 00:38:52,720 of one of these small commercial landers 1056 00:38:57,829 --> 00:38:55,040 and these companies then have plans to 1057 00:38:59,589 --> 00:38:57,839 increase the the scale and the scope of 1058 00:39:02,470 --> 00:38:59,599 these landers so they can carry more and 1059 00:39:03,349 --> 00:39:02,480 more to the surface so the human landers 1060 00:39:05,430 --> 00:39:03,359 are 1061 00:39:07,510 --> 00:39:05,440 like as kimberly said right now being 1062 00:39:08,230 --> 00:39:07,520 discussed with commercial companies as 1063 00:39:12,470 --> 00:39:08,240 to 1064 00:39:13,829 --> 00:39:12,480 build them going forward 1065 00:39:16,950 --> 00:39:13,839 it's really kind of exciting because 1066 00:39:19,349 --> 00:39:16,960 again this is a totally new paradigm we 1067 00:39:22,150 --> 00:39:19,359 nasa's always built 1068 00:39:24,310 --> 00:39:22,160 the landers with commercial companies 1069 00:39:27,030 --> 00:39:24,320 but they've done it in a 1070 00:39:29,349 --> 00:39:27,040 very much requirement driven process 1071 00:39:30,150 --> 00:39:29,359 we need you to build this for us okay 1072 00:39:31,910 --> 00:39:30,160 all right 1073 00:39:34,470 --> 00:39:31,920 this is very different this is i'm 1074 00:39:36,069 --> 00:39:34,480 buying my airline ticket to fly across 1075 00:39:37,750 --> 00:39:36,079 the country i'm not telling you how to 1076 00:39:39,990 --> 00:39:37,760 build your airplane right right you get 1077 00:39:42,630 --> 00:39:40,000 me there somehow exactly and that's what 1078 00:39:43,990 --> 00:39:42,640 we're doing now and um other um other 1079 00:39:46,710 --> 00:39:44,000 folks can 1080 00:39:48,670 --> 00:39:46,720 pay to use the services so it's um it 1081 00:39:51,430 --> 00:39:48,680 opens up the 1082 00:39:52,310 --> 00:39:51,440 accessibility of the moon 1083 00:39:59,430 --> 00:39:52,320 okay 1084 00:40:00,950 --> 00:39:59,440 chat a space space tv net wants to know 1085 00:40:03,190 --> 00:40:00,960 are any of these vehicles going to be 1086 00:40:05,589 --> 00:40:03,200 like the lunar roving vehicle 1087 00:40:07,910 --> 00:40:05,599 yeah there's actually commercial rovers 1088 00:40:09,829 --> 00:40:07,920 actually being discussed too so 1089 00:40:12,550 --> 00:40:09,839 nasa is working on some rovers as well 1090 00:40:14,309 --> 00:40:12,560 but uh and rovers come in all shapes and 1091 00:40:16,950 --> 00:40:14,319 sizes exactly 1092 00:40:19,030 --> 00:40:16,960 robotic but also for the uh humans 1093 00:40:21,270 --> 00:40:19,040 beyond 2024 1094 00:40:23,349 --> 00:40:21,280 uh there's definitely plans for large 1095 00:40:25,750 --> 00:40:23,359 even pressurized rovers that they would 1096 00:40:28,069 --> 00:40:25,760 go in so i see way beyond what we did in 1097 00:40:29,510 --> 00:40:28,079 the apollo era um i think the martian 1098 00:40:31,510 --> 00:40:29,520 remember the 1099 00:40:33,270 --> 00:40:31,520 pressure so but some of these commercial 1100 00:40:35,750 --> 00:40:33,280 landers the ones going in the next year 1101 00:40:37,030 --> 00:40:35,760 and a half or so are carrying very small 1102 00:40:43,990 --> 00:40:37,040 rovers 1103 00:40:46,069 --> 00:40:44,000 providing a service so 1104 00:40:47,910 --> 00:40:46,079 the landers provide the landed service 1105 00:40:49,990 --> 00:40:47,920 and commercial rovers can provide a 1106 00:40:52,710 --> 00:40:50,000 roving service okay so i can put my 1107 00:40:55,109 --> 00:40:52,720 instrument on a rover that 1108 00:40:56,870 --> 00:40:55,119 we can buy space on rather than nasa 1109 00:40:59,030 --> 00:40:56,880 having to build all that okay now 1110 00:41:02,150 --> 00:40:59,040 speaking of your instrument i know that 1111 00:41:04,230 --> 00:41:02,160 you have a good segue 1112 00:41:05,829 --> 00:41:04,240 that was perfect thanks tony 1113 00:41:08,230 --> 00:41:05,839 did you bring it today well i brought 1114 00:41:09,910 --> 00:41:08,240 part of it all right can you show us and 1115 00:41:12,470 --> 00:41:09,920 tell us what it's going to do up there i 1116 00:41:14,950 --> 00:41:12,480 don't drop it so something like this is 1117 00:41:18,390 --> 00:41:14,960 flying to the moon in the next year or 1118 00:41:20,870 --> 00:41:18,400 two yeah so this was selected to fly on 1119 00:41:22,710 --> 00:41:20,880 one of the three landers that is going 1120 00:41:24,150 --> 00:41:22,720 to the moon in the next few uh next 1121 00:41:26,950 --> 00:41:24,160 couple of years 1122 00:41:28,870 --> 00:41:26,960 and this is uh it's called nervous 1123 00:41:32,150 --> 00:41:28,880 nervous terrible 1124 00:41:37,270 --> 00:41:34,470 near infrared volatile spectrometer 1125 00:41:39,349 --> 00:41:37,280 system okay and what it does is it finds 1126 00:41:42,150 --> 00:41:39,359 water that's its principal purpose is to 1127 00:41:43,990 --> 00:41:42,160 find volatiles but especially water okay 1128 00:41:45,030 --> 00:41:44,000 so it's a prospecting instrument if you 1129 00:41:46,870 --> 00:41:45,040 think about 1130 00:41:48,790 --> 00:41:46,880 uh when we look for minerals and 1131 00:41:49,910 --> 00:41:48,800 resources on earth you prospect you go 1132 00:41:52,230 --> 00:41:49,920 and look at this is what this 1133 00:41:55,190 --> 00:41:52,240 instruments meant yeah yeah sniffing out 1134 00:41:56,870 --> 00:41:55,200 where the water is exactly and and this 1135 00:42:00,470 --> 00:41:56,880 is an engineering unit this is a unit 1136 00:42:02,150 --> 00:42:00,480 that we use to develop uh the technology 1137 00:42:04,630 --> 00:42:02,160 make sure we can make the measurements 1138 00:42:06,710 --> 00:42:04,640 and and meet the goals we want to meet 1139 00:42:08,069 --> 00:42:06,720 and then we then test it 1140 00:42:09,910 --> 00:42:08,079 in the similar environments it's going 1141 00:42:12,630 --> 00:42:09,920 to see for example it has to survive 1142 00:42:14,950 --> 00:42:12,640 launch landing oh yeah vacuum radiation 1143 00:42:16,870 --> 00:42:14,960 et cetera 1144 00:42:17,990 --> 00:42:16,880 test all that make sure it works and and 1145 00:42:20,230 --> 00:42:18,000 you can see it's just got a bunch of 1146 00:42:23,670 --> 00:42:20,240 eyes on it yeah 1147 00:42:25,829 --> 00:42:23,680 what else is going on there yeah so um 1148 00:42:28,309 --> 00:42:25,839 what what it's meant to an important 1149 00:42:30,150 --> 00:42:28,319 aspect of this is is it needs to work 1150 00:42:31,990 --> 00:42:30,160 both in sunlight and in darkness just 1151 00:42:33,589 --> 00:42:32,000 like kimberly was saying these are dark 1152 00:42:35,190 --> 00:42:33,599 craters some we're really interested in 1153 00:42:36,790 --> 00:42:35,200 because there's that correlation but we 1154 00:42:38,150 --> 00:42:36,800 yeah we have to go down there and we 1155 00:42:38,950 --> 00:42:38,160 have to look at the scales we're going 1156 00:42:40,550 --> 00:42:38,960 to 1157 00:42:42,390 --> 00:42:40,560 work out 1158 00:42:44,390 --> 00:42:42,400 because the data from orbit is giving us 1159 00:42:46,710 --> 00:42:44,400 hundreds of meter kind of footprints of 1160 00:42:48,710 --> 00:42:46,720 where the water is yeah this is going to 1161 00:42:50,710 --> 00:42:48,720 give us human scale you know things on 1162 00:42:53,829 --> 00:42:50,720 the meter and that's an unknown you know 1163 00:42:56,069 --> 00:42:53,839 so we do need to exactly that's exciting 1164 00:42:57,829 --> 00:42:56,079 so real quick this this if 1165 00:43:00,230 --> 00:42:57,839 this little guy right here i can't get 1166 00:43:03,109 --> 00:43:00,240 the nice blue shine of it that's this is 1167 00:43:05,030 --> 00:43:03,119 an infrared lamp oh yeah um and and the 1168 00:43:05,990 --> 00:43:05,040 intent of this is to actually 1169 00:43:07,670 --> 00:43:06,000 provide 1170 00:43:09,430 --> 00:43:07,680 infrared light for the other instruments 1171 00:43:11,750 --> 00:43:09,440 so it can see in the dark 1172 00:43:13,750 --> 00:43:11,760 likewise all these things over here 1173 00:43:15,270 --> 00:43:13,760 these little guys those are leds of 1174 00:43:16,790 --> 00:43:15,280 various colors 1175 00:43:18,710 --> 00:43:16,800 so they provide 1176 00:43:21,589 --> 00:43:18,720 illumination from the ultraviolet to the 1177 00:43:23,109 --> 00:43:21,599 near infrared uh for our camera system 1178 00:43:25,270 --> 00:43:23,119 which is right here this is a lens to 1179 00:43:28,069 --> 00:43:25,280 the camera system this black thing this 1180 00:43:29,990 --> 00:43:28,079 allows us to image the area at very high 1181 00:43:32,870 --> 00:43:30,000 resolution understand the chemical 1182 00:43:34,870 --> 00:43:32,880 makeup the mineralogy the morphology 1183 00:43:36,870 --> 00:43:34,880 and things like that and the last thing 1184 00:43:38,470 --> 00:43:36,880 are the four sensors right underneath uh 1185 00:43:39,670 --> 00:43:38,480 the camera these four right here this is 1186 00:43:41,510 --> 00:43:39,680 really hard to do it's like doing it in 1187 00:43:43,589 --> 00:43:41,520 the mirror 1188 00:43:44,870 --> 00:43:43,599 those are thermal sensors it's a thermal 1189 00:43:47,349 --> 00:43:44,880 radiometer 1190 00:43:48,870 --> 00:43:47,359 and what that does is allows us to 1191 00:43:50,790 --> 00:43:48,880 measure temperatures of the scene we're 1192 00:43:53,349 --> 00:43:50,800 looking at because we're interested in 1193 00:43:54,790 --> 00:43:53,359 not only understanding if water is there 1194 00:43:56,790 --> 00:43:54,800 but we don't want to understand the 1195 00:43:58,710 --> 00:43:56,800 environment we are finding water or not 1196 00:44:00,630 --> 00:43:58,720 finding water because ultimately we will 1197 00:44:02,150 --> 00:44:00,640 use this data to build what is called a 1198 00:44:03,670 --> 00:44:02,160 resource map on earth we call them a 1199 00:44:07,190 --> 00:44:03,680 mineral mineral map that's what the 1200 00:44:08,710 --> 00:44:07,200 united states geological survey provides 1201 00:44:10,870 --> 00:44:08,720 to a company that's interested in 1202 00:44:12,790 --> 00:44:10,880 finding minerals and and we're going to 1203 00:44:15,750 --> 00:44:12,800 do this on the moon basically build 1204 00:44:17,510 --> 00:44:15,760 these maps and understand the location 1205 00:44:19,349 --> 00:44:17,520 this is one instrument of several that 1206 00:44:21,910 --> 00:44:19,359 is dedicated to do this kind of work oh 1207 00:44:23,910 --> 00:44:21,920 yeah yeah all working in tandem and yeah 1208 00:44:27,109 --> 00:44:23,920 exactly together a map together maybe 1209 00:44:28,710 --> 00:44:27,119 yeah yeah exactly i see that makes sense 1210 00:44:30,550 --> 00:44:28,720 and i'm trying to convince tony that the 1211 00:44:32,390 --> 00:44:30,560 next iteration of this is to be handheld 1212 00:44:34,470 --> 00:44:32,400 by the astronauts 1213 00:44:42,470 --> 00:44:34,480 the astronauts go and look at like okay 1214 00:44:47,430 --> 00:44:45,990 it's on all right do you have a question 1215 00:44:49,750 --> 00:44:47,440 so 1216 00:44:51,430 --> 00:44:49,760 guard chose wants to know how is nasa 1217 00:44:53,190 --> 00:44:51,440 going to protect these rovers from lunar 1218 00:44:57,030 --> 00:44:53,200 dust 1219 00:44:59,030 --> 00:44:57,040 it is 1220 00:45:00,550 --> 00:44:59,040 and it's really is unique in that it's 1221 00:45:01,829 --> 00:45:00,560 only generated because of the 1222 00:45:04,309 --> 00:45:01,839 environment on the moon it's generated 1223 00:45:06,150 --> 00:45:04,319 through the impact processes and so the 1224 00:45:08,550 --> 00:45:06,160 dust and it's never eroded there's no 1225 00:45:11,190 --> 00:45:08,560 way there's no there's no wind to make 1226 00:45:14,309 --> 00:45:11,200 or water or flowing liquid water to 1227 00:45:17,030 --> 00:45:14,319 smooth things out so it's jagged and 1228 00:45:18,870 --> 00:45:17,040 jagged it locks in place 1229 00:45:20,390 --> 00:45:18,880 and the apollo astronauts you know 1230 00:45:22,550 --> 00:45:20,400 complained about you know got into their 1231 00:45:24,790 --> 00:45:22,560 lungs and they scratched their suits the 1232 00:45:27,510 --> 00:45:24,800 suits were all ripped to shreds 1233 00:45:29,109 --> 00:45:27,520 so it is it is a beast 1234 00:45:30,710 --> 00:45:29,119 and the way you protect there's a lot of 1235 00:45:32,309 --> 00:45:30,720 ways you can protect it everything from 1236 00:45:33,430 --> 00:45:32,319 electrostatic barriers they're working 1237 00:45:36,309 --> 00:45:33,440 on so 1238 00:45:38,710 --> 00:45:36,319 one nice thing about the uh a lot of the 1239 00:45:41,910 --> 00:45:38,720 lunar dust is it has a magnetic property 1240 00:45:44,230 --> 00:45:41,920 to it it's got some uh ferric iron in it 1241 00:45:46,710 --> 00:45:44,240 nanophase iron and so you can actually 1242 00:45:53,589 --> 00:45:46,720 repulse it with electric fields um you 1243 00:45:57,750 --> 00:45:55,829 and also a number of other mechanical 1244 00:45:59,670 --> 00:45:57,760 gasket materials basically things that 1245 00:46:00,630 --> 00:45:59,680 go between bearings on wheels and 1246 00:46:03,349 --> 00:46:00,640 whatnot 1247 00:46:04,230 --> 00:46:03,359 that make it very diff difficult for the 1248 00:46:06,309 --> 00:46:04,240 dust 1249 00:46:07,829 --> 00:46:06,319 to get to the bearings of the the the 1250 00:46:09,910 --> 00:46:07,839 delicate parts these are kind of 1251 00:46:11,670 --> 00:46:09,920 torturous paths it has to follow and 1252 00:46:13,670 --> 00:46:11,680 we're fortunate that there's been a 1253 00:46:15,510 --> 00:46:13,680 couple of lunar simulants that have been 1254 00:46:17,990 --> 00:46:15,520 made modeled on the regular that was 1255 00:46:19,030 --> 00:46:18,000 brought by the apollo astronauts and so 1256 00:46:20,630 --> 00:46:19,040 um 1257 00:46:23,030 --> 00:46:20,640 companies and engineers who are looking 1258 00:46:24,790 --> 00:46:23,040 at wheel design and rover design they 1259 00:46:26,710 --> 00:46:24,800 can test out 1260 00:46:28,630 --> 00:46:26,720 their designs as best as possible with 1261 00:46:29,990 --> 00:46:28,640 this kind of jagged kind of stimulant i 1262 00:46:31,190 --> 00:46:30,000 mean obviously it's not a one-to-one 1263 00:46:33,270 --> 00:46:31,200 connection in fact one of the big 1264 00:46:34,790 --> 00:46:33,280 mysteries about 1265 00:46:37,670 --> 00:46:34,800 the um 1266 00:46:39,349 --> 00:46:37,680 permanently shadow regions um when rl 1267 00:46:42,230 --> 00:46:39,359 cross experiment that we did it a decade 1268 00:46:44,150 --> 00:46:42,240 ago finding water in cabela's um it 1269 00:46:45,349 --> 00:46:44,160 revealed that perhaps the the regolith 1270 00:46:46,630 --> 00:46:45,359 and those permanently shallow craters 1271 00:46:48,470 --> 00:46:46,640 are actually different than the 1272 00:46:50,309 --> 00:46:48,480 regulator that was found on the apollo 1273 00:46:51,670 --> 00:46:50,319 sites oh it's different so 1274 00:46:53,589 --> 00:46:51,680 there's going to be some learning to be 1275 00:46:55,589 --> 00:46:53,599 done so the engineers will do the best 1276 00:46:57,670 --> 00:46:55,599 knowledge they have now using a simulant 1277 00:46:59,589 --> 00:46:57,680 designing the wheels and the excavation 1278 00:47:01,190 --> 00:46:59,599 we're gonna have challenges with drills 1279 00:47:02,870 --> 00:47:01,200 and scoops and all that the same thing 1280 00:47:04,870 --> 00:47:02,880 to deal with the beast that is the dust 1281 00:47:07,589 --> 00:47:04,880 yes but we'll overcome those but we're 1282 00:47:09,190 --> 00:47:07,599 gonna have to get there on the scene at 1283 00:47:11,190 --> 00:47:09,200 the south pole 1284 00:47:12,950 --> 00:47:11,200 and the polar regions and go hmm that 1285 00:47:14,790 --> 00:47:12,960 dust is different yeah that's what we're 1286 00:47:17,510 --> 00:47:14,800 going to do next time all right 1287 00:47:19,750 --> 00:47:17,520 that question foreshadowed 1288 00:47:21,109 --> 00:47:19,760 my favorite section of the day uh you 1289 00:47:22,790 --> 00:47:21,119 guys described the south pole as 1290 00:47:24,710 --> 00:47:22,800 unexplored territory and you keep 1291 00:47:26,950 --> 00:47:24,720 referencing that it's really extreme 1292 00:47:28,470 --> 00:47:26,960 it's going to be tough so let's go 1293 00:47:30,230 --> 00:47:28,480 through some of those specific 1294 00:47:31,030 --> 00:47:30,240 challenges i mean it's it's like you 1295 00:47:32,950 --> 00:47:31,040 know 1296 00:47:35,190 --> 00:47:32,960 wanting to go in the deepest minds on 1297 00:47:37,670 --> 00:47:35,200 earth oh really and the deep you know 1298 00:47:39,430 --> 00:47:37,680 the deepest undersea exploration you 1299 00:47:40,870 --> 00:47:39,440 know it is because it's so different 1300 00:47:41,910 --> 00:47:40,880 from what we're used to or is it really 1301 00:47:46,549 --> 00:47:41,920 deep 1302 00:47:48,390 --> 00:47:46,559 is extreme it's completely 1303 00:47:51,190 --> 00:47:48,400 unlike a lot of the department who saw 1304 00:47:53,589 --> 00:47:51,200 the lower latitudes they landed in flat 1305 00:47:55,270 --> 00:47:53,599 areas okay nice pristine that's when i 1306 00:47:57,910 --> 00:47:55,280 picture the moon and 1307 00:47:59,829 --> 00:47:57,920 will be landing perhaps in areas that 1308 00:48:02,470 --> 00:47:59,839 are ridges that are sitting on top of a 1309 00:48:06,309 --> 00:48:02,480 crater that looks down into a 1310 00:48:09,349 --> 00:48:06,319 six kilometer hole so i was like that's 1311 00:48:10,790 --> 00:48:09,359 yeah exactly about three miles down and 1312 00:48:13,270 --> 00:48:10,800 and you can stay they'll be standing on 1313 00:48:16,390 --> 00:48:13,280 the edge of these vistas overlooking wow 1314 00:48:18,230 --> 00:48:16,400 mountains that are many miles high wow 1315 00:48:21,270 --> 00:48:18,240 into craters that are 1316 00:48:23,190 --> 00:48:21,280 uh 10 miles across and 1317 00:48:24,470 --> 00:48:23,200 three miles deep i never knew it was 1318 00:48:26,790 --> 00:48:24,480 that extreme and then the lighting 1319 00:48:28,950 --> 00:48:26,800 conditions um because of the low angle 1320 00:48:31,750 --> 00:48:28,960 of the sun you can have shadows that are 1321 00:48:33,750 --> 00:48:31,760 being cast from a ridge of a crater 1322 00:48:35,829 --> 00:48:33,760 that's hundreds of kilometers away 1323 00:48:38,549 --> 00:48:35,839 really and the shadows will be sweeping 1324 00:48:40,309 --> 00:48:38,559 across you over time skills of hours and 1325 00:48:42,549 --> 00:48:40,319 as we mentioned earlier when you're in 1326 00:48:43,750 --> 00:48:42,559 shadow your temperature drops and so 1327 00:48:45,030 --> 00:48:43,760 you're going to be experienced of course 1328 00:48:47,910 --> 00:48:45,040 you're in a 1329 00:48:49,589 --> 00:48:47,920 suit that's keeping you regulated but if 1330 00:48:51,670 --> 00:48:49,599 you think about it the whole 1331 00:48:53,589 --> 00:48:51,680 lighting condition the whole dealing 1332 00:48:56,309 --> 00:48:53,599 with the swing of temperatures is going 1333 00:48:57,829 --> 00:48:56,319 to stress out your system so 1334 00:48:59,750 --> 00:48:57,839 your equipment your machine and 1335 00:49:01,750 --> 00:48:59,760 everything and there are areas where 1336 00:49:03,109 --> 00:49:01,760 there's this permanent shadow darkness 1337 00:49:05,109 --> 00:49:03,119 is prone to darkness but there's also 1338 00:49:07,510 --> 00:49:05,119 areas that have what i like to say 1339 00:49:09,589 --> 00:49:07,520 persistent sunlight so there are some of 1340 00:49:11,750 --> 00:49:09,599 these peaks because they're so extreme 1341 00:49:14,150 --> 00:49:11,760 that no matter what time it 1342 00:49:17,109 --> 00:49:14,160 year it is it has 1343 00:49:18,950 --> 00:49:17,119 very often sunlight at it so it's often 1344 00:49:20,950 --> 00:49:18,960 at the rims or or crests of some of 1345 00:49:22,069 --> 00:49:20,960 these ridges near these craters and so 1346 00:49:23,829 --> 00:49:22,079 those are very attractive for the 1347 00:49:25,589 --> 00:49:23,839 reasons kim said is you won't be getting 1348 00:49:28,230 --> 00:49:25,599 these deep shadows sweeping across you 1349 00:49:29,670 --> 00:49:28,240 all that often right and when they do it 1350 00:49:32,710 --> 00:49:29,680 might just be for 1351 00:49:35,109 --> 00:49:32,720 five six seven days as opposed to 1352 00:49:36,150 --> 00:49:35,119 you know three months and something like 1353 00:49:37,990 --> 00:49:36,160 that so 1354 00:49:40,230 --> 00:49:38,000 so these are uh and they're great places 1355 00:49:42,150 --> 00:49:40,240 to put your power station exactly 1356 00:49:44,069 --> 00:49:42,160 and have some of your infrastructure 1357 00:49:45,910 --> 00:49:44,079 again it's sort of you know if you're 1358 00:49:47,589 --> 00:49:45,920 going to explore and you you're learning 1359 00:49:49,109 --> 00:49:47,599 about where you're exploring take 1360 00:49:50,710 --> 00:49:49,119 advantage of 1361 00:49:52,390 --> 00:49:50,720 the gifts that were given to you by 1362 00:49:54,870 --> 00:49:52,400 nature 1363 00:49:57,190 --> 00:49:54,880 and also be aware of the dangers you 1364 00:49:58,950 --> 00:49:57,200 know of course so you keep talking about 1365 00:50:01,349 --> 00:49:58,960 those the polls we actually have this 1366 00:50:03,750 --> 00:50:01,359 really cool anime our video 1367 00:50:06,309 --> 00:50:03,760 showing uh some light cycles at the moon 1368 00:50:07,910 --> 00:50:06,319 south pole exactly right yeah yeah 1369 00:50:09,270 --> 00:50:07,920 so can you tell us what we're seeing 1370 00:50:09,890 --> 00:50:09,280 this is 1371 00:50:11,589 --> 00:50:09,900 light falling 1372 00:50:14,470 --> 00:50:11,599 [Music] 1373 00:50:16,150 --> 00:50:14,480 we started at a low um latitudes looking 1374 00:50:18,710 --> 00:50:16,160 at the moon as we see the moon and what 1375 00:50:21,670 --> 00:50:18,720 you saw was the the sun moving 1376 00:50:23,270 --> 00:50:21,680 across the face of the moon there is no 1377 00:50:25,270 --> 00:50:23,280 dark side of the moon 1378 00:50:27,430 --> 00:50:25,280 every side of the moon gets sunlight 1379 00:50:29,349 --> 00:50:27,440 at some point we get 14 days of sunlight 1380 00:50:31,109 --> 00:50:29,359 14 days of darkness and we just don't 1381 00:50:33,670 --> 00:50:31,119 see that we just don't see that because 1382 00:50:35,109 --> 00:50:33,680 we always see the near side now this 1383 00:50:37,030 --> 00:50:35,119 what's done is this 1384 00:50:39,109 --> 00:50:37,040 movie's swung down so you're looking at 1385 00:50:41,030 --> 00:50:39,119 the south pole of the moon that crater 1386 00:50:43,589 --> 00:50:41,040 nice circular one right in the middle 1387 00:50:45,349 --> 00:50:43,599 that shackleton crater is almost exactly 1388 00:50:47,990 --> 00:50:45,359 at the south pole of the moon 1389 00:50:49,829 --> 00:50:48,000 it is about 15 miles across and about 1390 00:50:52,150 --> 00:50:49,839 four miles deep 1391 00:50:53,990 --> 00:50:52,160 and what you see are these shadows that 1392 00:50:57,109 --> 00:50:54,000 are sweeping across and it's because 1393 00:50:59,190 --> 00:50:57,119 again as kim kimberly explained earlier 1394 00:51:01,109 --> 00:50:59,200 the tilt of the moon on its axis is very 1395 00:51:03,030 --> 00:51:01,119 small so 1396 00:51:05,750 --> 00:51:03,040 the sun's always just hugging the 1397 00:51:07,829 --> 00:51:05,760 horizon creating these shadows 1398 00:51:10,309 --> 00:51:07,839 and and you can see in some of these 1399 00:51:12,470 --> 00:51:10,319 craters like the big shackleton itself 1400 00:51:14,390 --> 00:51:12,480 and the larger ones just above it 1401 00:51:16,309 --> 00:51:14,400 the floors of those craters never get 1402 00:51:17,910 --> 00:51:16,319 sunlight they are in permanent shadow 1403 00:51:18,549 --> 00:51:17,920 they just say dark you can just stare at 1404 00:51:30,720 --> 00:51:18,559 a 1405 00:51:32,150 --> 00:51:30,730 sunlight 1406 00:51:34,630 --> 00:51:32,160 [Music] 1407 00:51:36,150 --> 00:51:34,640 they stayed light yeah yeah so extreme 1408 00:51:38,230 --> 00:51:36,160 so lighting conditions are extreme 1409 00:51:40,630 --> 00:51:38,240 topography is extreme temperatures are 1410 00:51:43,510 --> 00:51:40,640 extreme the dust we sort of know what 1411 00:51:44,790 --> 00:51:43,520 it's made of but maybe not um 1412 00:51:46,150 --> 00:51:44,800 [Music] 1413 00:51:48,549 --> 00:51:46,160 yeah but it could have some other 1414 00:51:50,230 --> 00:51:48,559 benefits too we just have to we haven't 1415 00:51:52,870 --> 00:51:50,240 explored it mm-hmm and we haven't 1416 00:51:54,950 --> 00:51:52,880 explored it with robots yet either so 1417 00:51:56,549 --> 00:51:54,960 and humans and somebody's boots on the 1418 00:51:58,870 --> 00:51:56,559 ground and in general we see this 1419 00:52:00,950 --> 00:51:58,880 increase of hydrogen at the poles 1420 00:52:04,309 --> 00:52:00,960 and we've seen increase in hydration of 1421 00:52:06,630 --> 00:52:04,319 the soils meaning hydroxyl oh or water 1422 00:52:08,710 --> 00:52:06,640 molecules bound to the soils even in 1423 00:52:10,950 --> 00:52:08,720 sunlight right in 1424 00:52:13,829 --> 00:52:10,960 increased amounts towards the poles 1425 00:52:15,349 --> 00:52:13,839 so just the composition and even in the 1426 00:52:17,510 --> 00:52:15,359 sunlight areas is going to be different 1427 00:52:19,030 --> 00:52:17,520 from anything we've ever seen before wow 1428 00:52:20,549 --> 00:52:19,040 and um that's going to just make the 1429 00:52:21,990 --> 00:52:20,559 modelers go crazy because we're going to 1430 00:52:23,829 --> 00:52:22,000 have a lot of a lot of tony's types of 1431 00:52:25,109 --> 00:52:23,839 instruments you know looking for the 1432 00:52:26,309 --> 00:52:25,119 water on these scales and then we're 1433 00:52:27,750 --> 00:52:26,319 going to try to piece together quite a 1434 00:52:29,430 --> 00:52:27,760 complex puzzle 1435 00:52:32,549 --> 00:52:29,440 um but it's a nice it's an interesting 1436 00:52:35,430 --> 00:52:32,559 puzzle to have i mean we're going 1437 00:52:37,990 --> 00:52:35,440 on the moon it's only been 10 years now 1438 00:52:39,510 --> 00:52:38,000 10 years is a it's not a long time but 1439 00:52:41,270 --> 00:52:39,520 it's long enough for like to realize 1440 00:52:42,710 --> 00:52:41,280 that you know this moon is a place that 1441 00:52:44,470 --> 00:52:42,720 we have full of things that we don't 1442 00:52:46,790 --> 00:52:44,480 know what's going on 1443 00:52:49,030 --> 00:52:46,800 it's more active than i ever it is it's 1444 00:52:50,309 --> 00:52:49,040 very active and more extreme especially 1445 00:52:52,790 --> 00:52:50,319 at the polls kind of picked a better 1446 00:52:55,270 --> 00:52:52,800 place to go exciting yeah you know 1447 00:52:57,829 --> 00:52:55,280 speaking of that uh you guys don't 1448 00:52:59,910 --> 00:52:57,839 forget if you do have any questions 1449 00:53:01,150 --> 00:52:59,920 please type them into the twitch chat 1450 00:53:05,349 --> 00:53:01,160 it's 1451 00:53:06,950 --> 00:53:05,359 www.twitch.nas twitch.tv backslash nasa 1452 00:53:08,230 --> 00:53:06,960 so we're going to move into our rapid 1453 00:53:09,870 --> 00:53:08,240 fire section 1454 00:53:12,309 --> 00:53:09,880 so uh 1455 00:53:14,710 --> 00:53:12,319 jesta578 wants to know about the nervous 1456 00:53:16,230 --> 00:53:14,720 instrument is it ultrasound ir and 1457 00:53:19,109 --> 00:53:16,240 visual 1458 00:53:20,630 --> 00:53:19,119 uh it is a little bit of everything so i 1459 00:53:21,910 --> 00:53:20,640 always like to say we go in with our 1460 00:53:23,670 --> 00:53:21,920 eyes wide open 1461 00:53:25,030 --> 00:53:23,680 for all the reasons kim just said 1462 00:53:26,309 --> 00:53:25,040 because you don't exactly know what 1463 00:53:27,190 --> 00:53:26,319 you're going to see 1464 00:53:28,790 --> 00:53:27,200 so 1465 00:53:31,190 --> 00:53:28,800 it is actually 1466 00:53:33,190 --> 00:53:31,200 a combination of near-infrared and for 1467 00:53:35,670 --> 00:53:33,200 you geeks out there that's between about 1468 00:53:38,549 --> 00:53:35,680 1.2 and 4 microns 1469 00:53:40,630 --> 00:53:38,559 thermal infrared that's between about 8 1470 00:53:43,030 --> 00:53:40,640 and 25 microns 1471 00:53:46,549 --> 00:53:43,040 and ultraviolet visible which is a we 1472 00:53:48,870 --> 00:53:46,559 run about um 0.35 to 1473 00:53:50,150 --> 00:53:48,880 0.94 microns 1474 00:53:51,990 --> 00:53:50,160 okay so 1475 00:53:54,230 --> 00:53:52,000 ultraviolet 1476 00:53:57,349 --> 00:53:54,240 colors that are below what we can see in 1477 00:53:59,910 --> 00:53:57,359 terms of our visual spectrum and 1478 00:54:01,990 --> 00:53:59,920 and energy is beyond what we can see in 1479 00:54:03,589 --> 00:54:02,000 into the thermal infrared yeah and then 1480 00:54:05,349 --> 00:54:03,599 what dona dunny had mentioned is that 1481 00:54:08,309 --> 00:54:05,359 this this this is the front end with the 1482 00:54:09,990 --> 00:54:08,319 cameras but the infrared um is going to 1483 00:54:11,670 --> 00:54:10,000 be connected to a spectrometer on the 1484 00:54:13,109 --> 00:54:11,680 back end okay because it's from the 1485 00:54:14,710 --> 00:54:13,119 spectrometer spreading the light out 1486 00:54:15,990 --> 00:54:14,720 into different wavelengths and it's over 1487 00:54:17,829 --> 00:54:16,000 the infrared that you're going to see 1488 00:54:20,069 --> 00:54:17,839 the water signature or the hydroxyl 1489 00:54:22,230 --> 00:54:20,079 signature and the minerals yeah and so 1490 00:54:24,390 --> 00:54:22,240 this is a very it's a compact instrument 1491 00:54:25,510 --> 00:54:24,400 with both cameras and thermal sensors to 1492 00:54:27,910 --> 00:54:25,520 get the temperature plus the 1493 00:54:29,190 --> 00:54:27,920 spectrometer to get the amount of 1494 00:54:30,950 --> 00:54:29,200 composition 1495 00:54:32,950 --> 00:54:30,960 yeah what things are made out of all 1496 00:54:35,990 --> 00:54:32,960 right so let's see 1497 00:54:38,789 --> 00:54:36,000 dude is dudette wants to know is there a 1498 00:54:41,510 --> 00:54:38,799 sample return plan for lunar water 1499 00:54:43,589 --> 00:54:41,520 yeah that's uh absolutely 1500 00:54:45,510 --> 00:54:43,599 they do want to return uh yeah but the 1501 00:54:47,750 --> 00:54:45,520 question is will it happen 1502 00:54:48,789 --> 00:54:47,760 it will happen with the humans going in 1503 00:54:50,150 --> 00:54:48,799 2024 because they're going to bring 1504 00:54:51,829 --> 00:54:50,160 samples back okay don't worry we're 1505 00:54:53,750 --> 00:54:51,839 going to be so excited that 1506 00:54:55,430 --> 00:54:53,760 question is will we get a rover to get 1507 00:54:58,069 --> 00:54:55,440 us a sample return before the humans 1508 00:55:00,230 --> 00:54:58,079 don't know yet that would be awesome too 1509 00:55:01,589 --> 00:55:00,240 um but yeah we're certainly going to get 1510 00:55:03,109 --> 00:55:01,599 something we're going to get something 1511 00:55:04,630 --> 00:55:03,119 and specifically there's a lot of 1512 00:55:06,549 --> 00:55:04,640 discussion about 1513 00:55:08,950 --> 00:55:06,559 cryogenic sampling because when you 1514 00:55:10,950 --> 00:55:08,960 sample something that's at minus 230 1515 00:55:12,230 --> 00:55:10,960 degrees below centigrade 1516 00:55:13,430 --> 00:55:12,240 uh 1517 00:55:14,710 --> 00:55:13,440 there's a lot of debate right now 1518 00:55:16,950 --> 00:55:14,720 whether or not you need to keep it that 1519 00:55:18,950 --> 00:55:16,960 cold yeah or do you just need to seal it 1520 00:55:20,870 --> 00:55:18,960 and make sure you don't lose as it 1521 00:55:23,030 --> 00:55:20,880 sublimes as it warms and the ice is 1522 00:55:25,109 --> 00:55:23,040 sublime yeah i was on a mission concept 1523 00:55:26,549 --> 00:55:25,119 for sampling off a comet and we had that 1524 00:55:27,990 --> 00:55:26,559 same debate because we're going to bring 1525 00:55:30,150 --> 00:55:28,000 it back to the earth the question is you 1526 00:55:31,030 --> 00:55:30,160 keep it in cryo storage or do you allow 1527 00:55:32,710 --> 00:55:31,040 it to 1528 00:55:34,470 --> 00:55:32,720 come up to room temperature but then 1529 00:55:35,589 --> 00:55:34,480 you've lost some information but you're 1530 00:55:36,789 --> 00:55:35,599 right they're gonna have to solve that 1531 00:55:38,150 --> 00:55:36,799 issue i never thought about that you're 1532 00:55:39,430 --> 00:55:38,160 right yeah we're gonna bring back our 1533 00:55:40,870 --> 00:55:39,440 water samples from the moon we're gonna 1534 00:55:42,630 --> 00:55:40,880 have to have something cold you need a 1535 00:55:46,950 --> 00:55:42,640 couple years definitely yeah get me a 1536 00:55:52,950 --> 00:55:50,470 as yeah so it looks like grundian wants 1537 00:55:54,630 --> 00:55:52,960 to know he wonders what is the moon 1538 00:55:56,630 --> 00:55:54,640 smelling what does the air smell like on 1539 00:55:58,150 --> 00:55:56,640 the moon good question 1540 00:56:00,069 --> 00:55:58,160 well we don't know but according to the 1541 00:56:02,630 --> 00:56:00,079 apollo tapes they smell they said it 1542 00:56:04,549 --> 00:56:02,640 smelled like gun powder gun powder that 1543 00:56:06,470 --> 00:56:04,559 was the the it's reported by several of 1544 00:56:07,829 --> 00:56:06,480 the astronauts um so my husband and i 1545 00:56:10,590 --> 00:56:07,839 are geeks we kind of listen to the audio 1546 00:56:14,230 --> 00:56:10,600 tapes of all the apologies 1547 00:56:17,589 --> 00:56:15,829 and more than once they would say it 1548 00:56:19,349 --> 00:56:17,599 smelled like gunpowder i have no idea 1549 00:56:20,710 --> 00:56:19,359 whether that would be true i mean it 1550 00:56:22,069 --> 00:56:20,720 just and that's error to be clear 1551 00:56:23,430 --> 00:56:22,079 there's air in the capsule that's the 1552 00:56:25,109 --> 00:56:23,440 air in the capsule when they got in 1553 00:56:26,470 --> 00:56:25,119 after their evas is extra vehicle 1554 00:56:27,829 --> 00:56:26,480 activity and are romping around on the 1555 00:56:29,430 --> 00:56:27,839 surface and they're coming back in and 1556 00:56:32,950 --> 00:56:29,440 they're taking off their coat that's 1557 00:56:34,950 --> 00:56:32,960 when they smell it because you know um 1558 00:56:35,990 --> 00:56:34,960 yeah they needed the atmosphere but 1559 00:56:37,589 --> 00:56:36,000 they're also in a pure oxidative 1560 00:56:39,190 --> 00:56:37,599 atmosphere i don't know if that changed 1561 00:56:41,109 --> 00:56:39,200 anything maybe it has something to do 1562 00:56:42,630 --> 00:56:41,119 with the dust they think it's because 1563 00:56:46,309 --> 00:56:42,640 again this dust is very unique it's 1564 00:56:49,109 --> 00:56:46,319 never been as it gets fractured and and 1565 00:56:50,549 --> 00:56:49,119 melted and re-solidified by impacts on 1566 00:56:53,109 --> 00:56:50,559 the surface it creates what are called 1567 00:56:54,710 --> 00:56:53,119 very um open active sites on the 1568 00:56:56,390 --> 00:56:54,720 surfaces that 1569 00:57:00,069 --> 00:56:56,400 again on earth we have all this oxygen 1570 00:57:04,069 --> 00:57:01,750 very very very little atmosphere it's 1571 00:57:06,390 --> 00:57:04,079 called an exosphere meaning a molecule 1572 00:57:08,390 --> 00:57:06,400 can leave the surface of the moon and 1573 00:57:09,990 --> 00:57:08,400 never encounter another another molecule 1574 00:57:24,390 --> 00:57:10,000 as long as it lives 1575 00:57:28,950 --> 00:57:26,150 and then somehow a hook up to it some 1576 00:57:32,230 --> 00:57:28,960 sniffing instrument that will 1577 00:57:33,750 --> 00:57:32,240 knows what molecules are in women 1578 00:57:35,270 --> 00:57:33,760 there's instruments with the nanotubes 1579 00:57:37,750 --> 00:57:35,280 that measure can measure specific 1580 00:57:39,349 --> 00:57:37,760 chemicals right right as they reach so 1581 00:57:41,190 --> 00:57:39,359 it's kind of like a smell 1582 00:57:42,549 --> 00:57:41,200 but then to extrapolate it to what we 1583 00:57:44,390 --> 00:57:42,559 would experience 1584 00:57:46,150 --> 00:57:44,400 yes that's very subjective yeah so the 1585 00:57:47,829 --> 00:57:46,160 dust has these open surfaces and reacts 1586 00:57:49,349 --> 00:57:47,839 with the oxygen in the capsule i was 1587 00:57:51,190 --> 00:57:49,359 wondering whether that made it that's 1588 00:57:52,950 --> 00:57:51,200 the comment that was made and that's our 1589 00:57:55,030 --> 00:57:52,960 only one data point right 1590 00:57:58,150 --> 00:57:55,040 so we're looking forward to more data 1591 00:58:03,270 --> 00:58:01,270 so sun cricket wants to know um will new 1592 00:58:05,430 --> 00:58:03,280 suits be made specifically for longer 1593 00:58:08,789 --> 00:58:05,440 stays on the martian surface 1594 00:58:11,030 --> 00:58:08,799 or sorry the moon surface 1595 00:58:13,030 --> 00:58:11,040 they are working on the next generation 1596 00:58:14,870 --> 00:58:13,040 suit and i'm afraid i don't know the 1597 00:58:16,950 --> 00:58:14,880 name of it the designation of it but 1598 00:58:18,950 --> 00:58:16,960 they are working on a new generation 1599 00:58:19,750 --> 00:58:18,960 suit that is meant to be 1600 00:58:23,270 --> 00:58:19,760 uh 1601 00:58:26,470 --> 00:58:23,280 more mobile a lot more mobility to it 1602 00:58:28,549 --> 00:58:26,480 um and to allow the astronauts to 1603 00:58:30,390 --> 00:58:28,559 uh be able to do things like that they 1604 00:58:33,349 --> 00:58:30,400 couldn't do on apollo for example if you 1605 00:58:34,870 --> 00:58:33,359 saw an astronaut fall over on apollo 1606 00:58:36,230 --> 00:58:34,880 they would have to do a push-up to get 1607 00:58:38,870 --> 00:58:36,240 themselves up they couldn't bend the 1608 00:58:41,510 --> 00:58:38,880 knees well enough to actually stand so 1609 00:58:43,190 --> 00:58:41,520 they'd have to do a push-up a few times 1610 00:58:50,420 --> 00:58:43,200 until they got enough momentum to get 1611 00:58:54,230 --> 00:58:52,150 [Music] 1612 00:58:56,150 --> 00:58:54,240 the fingernails of the astronauts were 1613 00:58:58,789 --> 00:58:56,160 crushed up against the edges of the 1614 00:59:00,069 --> 00:58:58,799 gloves and they were all bruised and 1615 00:59:02,150 --> 00:59:00,079 everything so 1616 00:59:03,910 --> 00:59:02,160 we want are the astronauts on the moon 1617 00:59:05,910 --> 00:59:03,920 to be very physically active excavating 1618 00:59:08,390 --> 00:59:05,920 all this water for us and building off 1619 00:59:09,349 --> 00:59:08,400 habitats and doing that so the new suits 1620 00:59:14,390 --> 00:59:09,359 are 1621 00:59:17,829 --> 00:59:14,400 here's a good one can i jump in with it 1622 00:59:19,670 --> 00:59:17,839 go for it terminus 1961. how do you 1623 00:59:21,829 --> 00:59:19,680 communicate with a probe down in the 1624 00:59:23,990 --> 00:59:21,839 crater what are the challenges 1625 00:59:26,870 --> 00:59:24,000 so this is kind of really interesting uh 1626 00:59:28,950 --> 00:59:26,880 point a a dark crater does not mean we 1627 00:59:32,150 --> 00:59:28,960 can't see into the crater from earth 1628 00:59:33,349 --> 00:59:32,160 uh-huh good point so um in one instance 1629 00:59:35,030 --> 00:59:33,359 you can use what's called direct to 1630 00:59:37,030 --> 00:59:35,040 earth communications that's where is 1631 00:59:40,950 --> 00:59:37,040 what we did in apollo or in this case 1632 00:59:44,789 --> 00:59:42,549 or depending on the geometry exactly 1633 00:59:47,349 --> 00:59:44,799 right right so in some instances yes you 1634 00:59:48,710 --> 00:59:47,359 can see earth from a psr from the floor 1635 00:59:49,670 --> 00:59:48,720 of a permanently shadowed region or 1636 00:59:51,109 --> 00:59:49,680 crater 1637 00:59:52,870 --> 00:59:51,119 other instances you'll be able to look 1638 00:59:54,470 --> 00:59:52,880 up overhead and see gateway 1639 00:59:57,270 --> 00:59:54,480 so you can relay you can look straight 1640 00:59:58,549 --> 00:59:57,280 up and talk to a relay satellite or 1641 01:00:00,069 --> 00:59:58,559 gateway 1642 01:00:01,750 --> 01:00:00,079 but they've also talked about having 1643 01:00:02,789 --> 01:00:01,760 repeaters yeah so some of these 1644 01:00:04,710 --> 01:00:02,799 commercial 1645 01:00:07,109 --> 01:00:04,720 service providers aren't just talking 1646 01:00:09,670 --> 01:00:07,119 about providing landed services i can 1647 01:00:11,430 --> 01:00:09,680 take you uh to the moon but they're also 1648 01:00:17,030 --> 01:00:11,440 talking about setting up infrastructure 1649 01:00:21,430 --> 01:00:19,670 the commercial uh landers that are going 1650 01:00:23,750 --> 01:00:21,440 actually will communicate with the small 1651 01:00:25,589 --> 01:00:23,760 rovers and whatnot with wi-fi okay and 1652 01:00:27,990 --> 01:00:25,599 they're actually talking about uh both 1653 01:00:29,349 --> 01:00:28,000 communication power all kinds of relay 1654 01:00:30,950 --> 01:00:29,359 systems building infrastructure to 1655 01:00:32,150 --> 01:00:30,960 actually assist in the exploration and 1656 01:00:34,390 --> 01:00:32,160 science and 1657 01:00:36,390 --> 01:00:34,400 build up that's cool yeah and that helps 1658 01:00:37,510 --> 01:00:36,400 me picture better the creator and 1659 01:00:38,789 --> 01:00:37,520 communicating 1660 01:00:40,230 --> 01:00:38,799 i mean if you're really deep in you're 1661 01:00:41,270 --> 01:00:40,240 going to have to go up but if you're you 1662 01:00:43,750 --> 01:00:41,280 know it depends on where you can put a 1663 01:00:46,230 --> 01:00:43,760 repeater true cool okay so i have 1664 01:00:47,829 --> 01:00:46,240 another question uh calcu's wants to 1665 01:00:49,670 --> 01:00:47,839 know are you going to send rovers to 1666 01:00:52,789 --> 01:00:49,680 these craters first 1667 01:00:56,630 --> 01:00:52,799 before we eventually send the next woman 1668 01:00:58,390 --> 01:00:56,640 or like the next person and if so when 1669 01:01:01,349 --> 01:00:58,400 uh we really want to 1670 01:01:03,109 --> 01:01:01,359 and uh we're working on plans along 1671 01:01:07,190 --> 01:01:03,119 those lines that 1672 01:01:09,829 --> 01:01:07,200 still are being formulated so um yes uh 1673 01:01:11,829 --> 01:01:09,839 you need mobility to really understand 1674 01:01:13,670 --> 01:01:11,839 the distribution of water 1675 01:01:15,430 --> 01:01:13,680 and and i think everyone appreciates 1676 01:01:17,109 --> 01:01:15,440 that so um 1677 01:01:18,549 --> 01:01:17,119 that is one of the higher priorities 1678 01:01:21,030 --> 01:01:18,559 right now to understand the resources at 1679 01:01:22,230 --> 01:01:21,040 the polls is to get a rover at the polls 1680 01:01:24,069 --> 01:01:22,240 at least one 1681 01:01:25,910 --> 01:01:24,079 and more you really probably want more 1682 01:01:27,510 --> 01:01:25,920 and to start prospecting and 1683 01:01:29,750 --> 01:01:27,520 characterizing and identifying and 1684 01:01:31,829 --> 01:01:29,760 that's the instrument i showed was built 1685 01:01:34,150 --> 01:01:31,839 specifically to go on a rover just like 1686 01:01:36,870 --> 01:01:34,160 that oh yeah yeah and so hopefully 1687 01:01:39,109 --> 01:01:36,880 before 2024. okay 1688 01:01:40,950 --> 01:01:39,119 i mean that's an ideal 1689 01:01:43,510 --> 01:01:40,960 situation but there's also alternative i 1690 01:01:44,789 --> 01:01:43,520 mean if if if we get the human uh 1691 01:01:47,030 --> 01:01:44,799 visiting the moon before we get the 1692 01:01:49,030 --> 01:01:47,040 rovers the rovers will go hand in hand i 1693 01:01:51,030 --> 01:01:49,040 mean it doesn't it doesn't slow down no 1694 01:01:53,589 --> 01:01:51,040 it's a whole architecture to get humans 1695 01:01:55,670 --> 01:01:53,599 2024 does not depend at all 1696 01:01:58,069 --> 01:01:55,680 because wherever the the astronauts are 1697 01:01:59,910 --> 01:01:58,079 going to land is unexplored territory 1698 01:02:01,510 --> 01:01:59,920 non-stop you know and they're going to 1699 01:02:02,870 --> 01:02:01,520 make so many discoveries they're going 1700 01:02:04,549 --> 01:02:02,880 to make so many discoveries and they're 1701 01:02:06,069 --> 01:02:04,559 going to be like we're going to do this 1702 01:02:07,510 --> 01:02:06,079 slightly different less i mean that's 1703 01:02:09,910 --> 01:02:07,520 exactly what happened on apollo with the 1704 01:02:12,150 --> 01:02:09,920 six landed missions each of them built 1705 01:02:13,670 --> 01:02:12,160 upon the experience of the prior oh yeah 1706 01:02:15,270 --> 01:02:13,680 and we all do that in science and in 1707 01:02:18,069 --> 01:02:15,280 engineering we learn what works what 1708 01:02:19,990 --> 01:02:18,079 doesn't work and we we expand 1709 01:02:21,589 --> 01:02:20,000 in fact perhaps we might have a scenario 1710 01:02:23,190 --> 01:02:21,599 where the humans get first men they're 1711 01:02:23,990 --> 01:02:23,200 going to like i want a rover to go over 1712 01:02:25,430 --> 01:02:24,000 there 1713 01:02:28,069 --> 01:02:25,440 because you know what i haven't yet 1714 01:02:29,829 --> 01:02:28,079 developed my harness to do repelling off 1715 01:02:31,750 --> 01:02:29,839 of cliff 1716 01:02:33,349 --> 01:02:31,760 but i know a rover can do it with you 1717 01:02:34,710 --> 01:02:33,359 know some sort of design and then you 1718 01:02:36,630 --> 01:02:34,720 know a couple years later i've got my 1719 01:02:38,870 --> 01:02:36,640 repelling harness ready to go so you 1720 01:02:40,950 --> 01:02:38,880 know okay could be that all right yeah a 1721 01:02:42,470 --> 01:02:40,960 little better so we have time for one 1722 01:02:44,630 --> 01:02:42,480 last question 1723 01:02:49,670 --> 01:02:44,640 uh so 1724 01:02:52,230 --> 01:02:49,680 triple x y h v h triple x wants to know 1725 01:02:54,150 --> 01:02:52,240 um is radioactivity uh really a major 1726 01:02:55,829 --> 01:02:54,160 concern when traveling to and from earth 1727 01:02:58,309 --> 01:02:55,839 and how does this radiation affect your 1728 01:03:00,230 --> 01:02:58,319 instruments 1729 01:03:01,510 --> 01:03:00,240 it is it absolutely is and it needs to 1730 01:03:02,549 --> 01:03:01,520 be designed 1731 01:03:04,549 --> 01:03:02,559 into 1732 01:03:06,710 --> 01:03:04,559 all your considerations both for the 1733 01:03:07,589 --> 01:03:06,720 instruments and for humans 1734 01:03:09,109 --> 01:03:07,599 and so 1735 01:03:11,349 --> 01:03:09,119 our instrument 1736 01:03:13,190 --> 01:03:11,359 uses components and electronic parts 1737 01:03:15,190 --> 01:03:13,200 that are what was called flight 1738 01:03:17,510 --> 01:03:15,200 qualified for flight and what the what 1739 01:03:19,829 --> 01:03:17,520 that means is they've undergone testing 1740 01:03:22,309 --> 01:03:19,839 to show that radiation doesn't affect 1741 01:03:24,630 --> 01:03:22,319 them okay and for electronics we've been 1742 01:03:25,990 --> 01:03:24,640 sending probes to pluto and the voyagers 1743 01:03:27,430 --> 01:03:26,000 have left the syst you know the solar 1744 01:03:29,109 --> 01:03:27,440 system time and space so from an 1745 01:03:31,670 --> 01:03:29,119 electronics point of view we're kind of 1746 01:03:32,710 --> 01:03:31,680 smart on making things robust i mean the 1747 01:03:34,549 --> 01:03:32,720 challenges are when you have new 1748 01:03:35,829 --> 01:03:34,559 materials and really smaller transistors 1749 01:03:38,069 --> 01:03:35,839 transistors and the like that you'll 1750 01:03:41,029 --> 01:03:38,079 have to do but we have facilities here 1751 01:03:43,430 --> 01:03:41,039 to test them okay so um for that for the 1752 01:03:44,549 --> 01:03:43,440 the biology is the the other yeah so the 1753 01:03:46,470 --> 01:03:44,559 biology is the one that we're going to 1754 01:03:48,710 --> 01:03:46,480 have to be learning and adapting and 1755 01:03:49,670 --> 01:03:48,720 reacting to and being proactive as we go 1756 01:03:51,270 --> 01:03:49,680 forward 1757 01:03:53,589 --> 01:03:51,280 and also we're going to be wanting to 1758 01:03:54,549 --> 01:03:53,599 monitor um when the big solar storms 1759 01:03:56,309 --> 01:03:54,559 come 1760 01:03:58,069 --> 01:03:56,319 our understanding i mean we have 1761 01:04:00,870 --> 01:03:58,079 sentinels out in space right now that 1762 01:04:02,549 --> 01:04:00,880 are monitoring the solar um behavior and 1763 01:04:04,230 --> 01:04:02,559 whenever we get these solar storms that 1764 01:04:05,270 --> 01:04:04,240 could you know uh 1765 01:04:06,309 --> 01:04:05,280 you know when it happens and our 1766 01:04:09,270 --> 01:04:06,319 astronauts are on the international 1767 01:04:11,109 --> 01:04:09,280 space station um they go to a certain 1768 01:04:13,109 --> 01:04:11,119 part of the space station that's more 1769 01:04:15,349 --> 01:04:13,119 safer a safer place we're going to have 1770 01:04:17,029 --> 01:04:15,359 scenarios like that with our humans on 1771 01:04:20,230 --> 01:04:17,039 the moon as well and on you know 1772 01:04:22,789 --> 01:04:20,240 wherever they are next uh so uh it is a 1773 01:04:24,309 --> 01:04:22,799 concern but it's it's uh we're gonna 1774 01:04:26,549 --> 01:04:24,319 learn and we're gonna adapt and we're 1775 01:04:28,710 --> 01:04:26,559 gonna um you know 1776 01:04:30,950 --> 01:04:28,720 react and be also preventing things 1777 01:04:32,950 --> 01:04:30,960 the only thing i'll add is uh another 1778 01:04:34,470 --> 01:04:32,960 great use of water is radiation 1779 01:04:36,710 --> 01:04:34,480 shielding one of the best radiation 1780 01:04:38,710 --> 01:04:36,720 shields there is is water so there are 1781 01:04:40,470 --> 01:04:38,720 discussions about using regolith but 1782 01:04:42,390 --> 01:04:40,480 also in the safe room where you really 1783 01:04:44,230 --> 01:04:42,400 need extra protection 1784 01:04:45,029 --> 01:04:44,240 you have a layer of water that you find 1785 01:04:54,789 --> 01:04:45,039 on 1786 01:04:56,069 --> 01:04:54,799 for the last ten years um 1787 01:04:58,230 --> 01:04:56,079 uh 1788 01:05:00,710 --> 01:04:58,240 has you know uncovered these places that 1789 01:05:01,990 --> 01:05:00,720 are lava tubes these underground caverns 1790 01:05:03,990 --> 01:05:02,000 in the moon 1791 01:05:04,870 --> 01:05:04,000 and they're also places that we have to 1792 01:05:07,190 --> 01:05:04,880 explore 1793 01:05:08,789 --> 01:05:07,200 they're not quite at the poles but once 1794 01:05:10,549 --> 01:05:08,799 we've set up this infrastructure to 1795 01:05:13,029 --> 01:05:10,559 allow us to go anywhere on the lunar 1796 01:05:14,870 --> 01:05:13,039 surface yeah i bet you an early 1797 01:05:16,470 --> 01:05:14,880 destination after going to the polls 1798 01:05:17,910 --> 01:05:16,480 will be good to explore the underground 1799 01:05:20,470 --> 01:05:17,920 caverns 1800 01:05:21,349 --> 01:05:20,480 and that's also a place for potentially 1801 01:05:23,430 --> 01:05:21,359 uh 1802 01:05:26,630 --> 01:05:23,440 you could take advantage of the you know 1803 01:05:28,630 --> 01:05:26,640 what nature gave you as a shield right 1804 01:05:30,710 --> 01:05:28,640 go underground or underground exactly 1805 01:05:32,549 --> 01:05:30,720 excellent very cool so maybe there's 1806 01:05:34,230 --> 01:05:32,559 lava tubes on mars too so that's right 1807 01:05:35,349 --> 01:05:34,240 so you can figure out if you can work 1808 01:05:38,150 --> 01:05:35,359 this whole thing out on the moon you've 1809 01:05:40,630 --> 01:05:38,160 got it sorted from mars excellent 1810 01:05:42,630 --> 01:05:40,640 we got it all figured out 1811 01:05:44,230 --> 01:05:42,640 we have to go and do it yeah 1812 01:05:47,510 --> 01:05:44,240 it's all we're all talk right now once 1813 01:05:51,750 --> 01:05:47,520 we do it right then we can say 1814 01:05:53,349 --> 01:05:51,760 we're ready we've got 1656 days to do it 1815 01:05:55,829 --> 01:05:53,359 yeah i was just going to say before we 1816 01:05:58,150 --> 01:05:55,839 have to wind up we've been talking about 1817 01:05:59,349 --> 01:05:58,160 all these challenges and you guys sound 1818 01:06:00,470 --> 01:05:59,359 confident that we're going to figure it 1819 01:06:02,230 --> 01:06:00,480 out but we're going to need a lot of 1820 01:06:05,109 --> 01:06:02,240 help right so there might be people 1821 01:06:07,190 --> 01:06:05,119 listening who want to get in on that so 1822 01:06:09,589 --> 01:06:07,200 do you guys have an answer for 1823 01:06:11,349 --> 01:06:09,599 what's a what's a good way to prepare to 1824 01:06:12,470 --> 01:06:11,359 help nasa tackle these challenges down 1825 01:06:14,630 --> 01:06:12,480 the road 1826 01:06:16,390 --> 01:06:14,640 are there particular you know majors in 1827 01:06:17,589 --> 01:06:16,400 college you would do or skills you would 1828 01:06:20,309 --> 01:06:17,599 develop 1829 01:06:22,470 --> 01:06:20,319 one thing is it's important to note that 1830 01:06:24,870 --> 01:06:22,480 this isn't going back to put a new 1831 01:06:26,390 --> 01:06:24,880 footprint on the moon and then come home 1832 01:06:28,789 --> 01:06:26,400 it really is 1833 01:06:31,349 --> 01:06:28,799 to be a sustained presence 1834 01:06:32,710 --> 01:06:31,359 that is 1835 01:06:34,470 --> 01:06:32,720 with within open architectures can 1836 01:06:36,309 --> 01:06:34,480 really describe so it's involving 1837 01:06:39,670 --> 01:06:36,319 everybody from the commercial side to 1838 01:06:42,069 --> 01:06:39,680 industry to governments foreign nasa 1839 01:06:44,309 --> 01:06:42,079 agencies all nasa agencies 1840 01:06:46,549 --> 01:06:44,319 so uh 1841 01:06:48,710 --> 01:06:46,559 i really do think we're at a 1842 01:06:51,029 --> 01:06:48,720 dawn of a new age of exploration 1843 01:06:53,109 --> 01:06:51,039 and so the opportunities are going to be 1844 01:06:54,950 --> 01:06:53,119 incredible and vast in terms of being 1845 01:06:57,430 --> 01:06:54,960 able to participate 1846 01:06:59,750 --> 01:06:57,440 uh not only within a government agency 1847 01:07:02,390 --> 01:06:59,760 to get into space but you can now go 1848 01:07:05,910 --> 01:07:02,400 work at a company and get into space 1849 01:07:08,470 --> 01:07:05,920 yeah and eventually i do not doubt that 1850 01:07:09,670 --> 01:07:08,480 there won't only be nasa astronauts 1851 01:07:12,069 --> 01:07:09,680 there will be 1852 01:07:13,190 --> 01:07:12,079 corporate astronauts interesting we're 1853 01:07:17,430 --> 01:07:13,200 gonna need people who know how to build 1854 01:07:19,430 --> 01:07:17,440 things and fix things
