1 00:00:00,000 --> 00:00:01,340 Picture this. 2 00:00:01,340 --> 00:00:04,000 Humanity not just visiting space, 3 00:00:04,000 --> 00:00:06,680 but like actually living there. 4 00:00:06,680 --> 00:00:07,520 Wow. 5 00:00:07,520 --> 00:00:08,520 Permanently. 6 00:00:08,520 --> 00:00:10,480 Beating homes on Mars, 7 00:00:10,480 --> 00:00:13,380 harvesting resources from asteroids, 8 00:00:13,380 --> 00:00:15,780 even turning the moon into a launch pad 9 00:00:15,780 --> 00:00:17,200 for deeper exploration. 10 00:00:17,200 --> 00:00:18,040 I like it. 11 00:00:18,040 --> 00:00:20,960 That's the future that your research dies into. 12 00:00:20,960 --> 00:00:23,480 And let me tell you, it's a wild ride. 13 00:00:23,480 --> 00:00:25,000 It is a wild ride. 14 00:00:25,000 --> 00:00:29,080 Welcome to Cosmos in a Pod, Space and Astronomy series. 15 00:00:29,080 --> 00:00:31,560 Today, we're strapping in 16 00:00:31,560 --> 00:00:33,960 for a deep dive into space colonization. 17 00:00:33,960 --> 00:00:34,800 Oh, right. 18 00:00:34,800 --> 00:00:37,640 Exploring the motivations, the locations, 19 00:00:37,640 --> 00:00:39,560 the mind blowing technology, 20 00:00:39,560 --> 00:00:41,520 and the hurdles that stand between us 21 00:00:41,520 --> 00:00:43,160 in a multi-planetary existence. 22 00:00:43,160 --> 00:00:44,000 That's a good one. 23 00:00:44,000 --> 00:00:44,820 It's a big one. 24 00:00:44,820 --> 00:00:46,240 What I find fascinating is that 25 00:00:46,240 --> 00:00:49,720 your sources don't just treat this as like sci-fi fantasy. 26 00:00:49,720 --> 00:00:53,560 They lay out a surprisingly pragmatic roadmap. 27 00:00:53,560 --> 00:00:55,480 Starting with the fundamental question, 28 00:00:55,480 --> 00:00:57,400 why bother leaving Earth at all? 29 00:00:57,400 --> 00:00:59,400 Right, because despite all our problems, 30 00:00:59,400 --> 00:01:01,160 Earth is still pretty comfy. 31 00:01:01,160 --> 00:01:04,160 Compared to, well, a barren rock in space. 32 00:01:04,160 --> 00:01:05,200 Pretty much, yeah. 33 00:01:05,200 --> 00:01:06,960 So what are these compelling reasons 34 00:01:06,960 --> 00:01:08,600 that your research highlights? 35 00:01:08,600 --> 00:01:11,900 Well, the sources converge on a few key arguments. 36 00:01:11,900 --> 00:01:13,680 One that really stood out is 37 00:01:15,200 --> 00:01:18,320 all our eggs in one basket problem. 38 00:01:18,320 --> 00:01:21,240 Earth is vulnerable to asteroid impacts, 39 00:01:21,240 --> 00:01:24,200 climate change, even pandemics. 40 00:01:24,200 --> 00:01:28,520 Far worse than we've seen colonizing space. 41 00:01:28,520 --> 00:01:30,800 It isn't just about expansion. 42 00:01:30,800 --> 00:01:34,360 It's about the long-term survival of humanity. 43 00:01:34,360 --> 00:01:35,800 So like a backup system. 44 00:01:35,800 --> 00:01:39,480 Yeah, just in case things go really south on Earth. 45 00:01:39,480 --> 00:01:41,320 Kind of a sobering thought. 46 00:01:41,320 --> 00:01:42,480 But I get the logic. 47 00:01:42,480 --> 00:01:43,760 I get the logic too. 48 00:01:43,760 --> 00:01:47,020 What else is driving this push beyond just safety? 49 00:01:47,020 --> 00:01:48,920 Well, your sources also point to 50 00:01:48,920 --> 00:01:51,940 the incredible resource potential of space. 51 00:01:51,940 --> 00:01:55,200 We're talking about asteroids packed with rare metals, 52 00:01:55,200 --> 00:01:57,240 water ice on the moon and Mars 53 00:01:57,240 --> 00:01:59,560 that could be turned into fuel. 54 00:01:59,560 --> 00:02:03,200 And solar energy on a scale we can barely comprehend. 55 00:02:03,200 --> 00:02:05,280 It's not just about surviving. 56 00:02:05,280 --> 00:02:06,840 It's about thriving. 57 00:02:06,840 --> 00:02:09,560 Okay, so that's starting to paint a more exciting picture. 58 00:02:09,560 --> 00:02:10,400 Little bit. 59 00:02:10,400 --> 00:02:14,200 But isn't there also a simple human drive to explore? 60 00:02:14,200 --> 00:02:15,040 Absolutely. 61 00:02:15,040 --> 00:02:16,720 Like we climbed the highest mountains, 62 00:02:16,720 --> 00:02:18,880 sailed the vastest oceans. 63 00:02:18,880 --> 00:02:21,480 Isn't space the next logical step? 64 00:02:21,480 --> 00:02:25,200 Several sources highlight the historical parallel. 65 00:02:25,200 --> 00:02:28,080 Two explorers setting out for new lands. 66 00:02:28,080 --> 00:02:31,600 Space colonization taps into that same spirit of discovery, 67 00:02:31,600 --> 00:02:34,560 pushing the boundaries of what humanity is capable of. 68 00:02:34,560 --> 00:02:37,520 And this time it's not just about claiming land. 69 00:02:37,520 --> 00:02:40,800 It's about potentially terraforming entire planets. 70 00:02:40,800 --> 00:02:42,880 Terraforming, wow, that's next level. 71 00:02:42,880 --> 00:02:44,000 That's next level. 72 00:02:44,000 --> 00:02:45,480 But before we get too carried away 73 00:02:45,480 --> 00:02:46,520 with transforming planets, 74 00:02:46,520 --> 00:02:48,560 let's figure out where we'd even set up camp. 75 00:02:48,560 --> 00:02:49,400 Good point. 76 00:02:49,400 --> 00:02:52,840 Your research seems to focus on a few key contenders 77 00:02:52,840 --> 00:02:55,000 for our first off-world homes. 78 00:02:55,000 --> 00:02:56,520 Right, the sources lay out 79 00:02:56,520 --> 00:02:59,120 a sort of cosmic real estate portfolio. 80 00:02:59,120 --> 00:02:59,960 I like that. 81 00:02:59,960 --> 00:03:02,200 Each with its own appeal and challenges. 82 00:03:02,200 --> 00:03:03,240 Okay, lay it on me. 83 00:03:03,240 --> 00:03:04,480 The moon, of course, 84 00:03:04,480 --> 00:03:09,280 is the closest and most familiar three days away. 85 00:03:09,280 --> 00:03:11,560 Potential water ice at the poles. 86 00:03:11,560 --> 00:03:14,120 And it could be a great testbed for technologies 87 00:03:14,120 --> 00:03:15,320 before we venture further. 88 00:03:15,320 --> 00:03:18,840 I can see the appeal of being close enough to Earth 89 00:03:18,840 --> 00:03:21,720 for somewhat regular visits. 90 00:03:21,720 --> 00:03:22,560 Right. 91 00:03:22,560 --> 00:03:23,520 But what about the downside? 92 00:03:23,520 --> 00:03:24,360 Yeah. 93 00:03:24,360 --> 00:03:26,440 Your research mentions some pretty harsh conditions 94 00:03:26,440 --> 00:03:27,680 on the lunar surface. 95 00:03:27,680 --> 00:03:28,920 That's where the challenges come in. 96 00:03:28,920 --> 00:03:29,760 Yeah. 97 00:03:29,760 --> 00:03:31,480 No atmosphere to speak of. 98 00:03:31,480 --> 00:03:32,320 Right. 99 00:03:32,320 --> 00:03:35,120 Wild temperature swings between lunar day and night, 100 00:03:35,120 --> 00:03:38,000 which last 14 Earth days each. 101 00:03:38,000 --> 00:03:38,840 Oh, wow. 102 00:03:38,840 --> 00:03:40,600 Building anything sustainable on the moon 103 00:03:40,600 --> 00:03:42,960 will require some serious innovation. 104 00:03:42,960 --> 00:03:45,760 Yeah, I mean, 14 days of darkness. 105 00:03:45,760 --> 00:03:46,600 Yeah. 106 00:03:46,600 --> 00:03:47,420 That's a long time. 107 00:03:47,420 --> 00:03:48,260 It's a long time. 108 00:03:48,260 --> 00:03:50,440 Okay, so maybe not the ideal vacation spot. 109 00:03:50,440 --> 00:03:51,400 Yeah, maybe not yet. 110 00:03:51,400 --> 00:03:53,440 But what about Mars? 111 00:03:53,440 --> 00:03:54,620 It seems like everyone's talking about 112 00:03:54,620 --> 00:03:56,560 colonizing the red planet these days. 113 00:03:56,560 --> 00:03:57,400 Right. 114 00:03:57,400 --> 00:03:58,220 What's the appeal there? 115 00:03:58,220 --> 00:04:00,760 Well, Mars is a fascinating prospect 116 00:04:00,760 --> 00:04:03,960 because it offers the most Earth-like environment 117 00:04:03,960 --> 00:04:05,140 in our solar system. 118 00:04:05,140 --> 00:04:09,680 It has water ice, a thin atmosphere, even some gravity. 119 00:04:09,680 --> 00:04:10,520 Okay. 120 00:04:10,520 --> 00:04:12,360 Though only about 38% of Earths. 121 00:04:12,360 --> 00:04:13,200 Right. 122 00:04:13,200 --> 00:04:15,760 Your sources suggest this makes it a prime candidate 123 00:04:15,760 --> 00:04:17,160 for terraforming. 124 00:04:17,160 --> 00:04:19,960 Potentially making it more habitable in the long run. 125 00:04:19,960 --> 00:04:24,160 That sounds almost pleasant. 126 00:04:24,160 --> 00:04:25,840 Yeah, relatively speaking. 127 00:04:25,840 --> 00:04:26,680 Relatively speaking. 128 00:04:26,680 --> 00:04:27,520 Yeah. 129 00:04:27,520 --> 00:04:30,080 But I bet there were some major drawbacks too, right? 130 00:04:30,080 --> 00:04:30,920 Oh, for sure. 131 00:04:30,920 --> 00:04:32,840 I mean, it's not exactly a short trip to Mars. 132 00:04:32,840 --> 00:04:35,720 The travel time is a major hurdle. 133 00:04:35,720 --> 00:04:36,560 Yeah. 134 00:04:36,560 --> 00:04:39,000 Six to nine months each way using current technology. 135 00:04:39,000 --> 00:04:39,840 Wow. 136 00:04:39,840 --> 00:04:42,360 Exposes astronauts to prolonged radiation. 137 00:04:42,360 --> 00:04:43,200 Right. 138 00:04:43,200 --> 00:04:44,880 And the psychological stress of confinement. 139 00:04:44,880 --> 00:04:45,720 Right. 140 00:04:45,720 --> 00:04:48,440 Mars has those infamous dust storms. 141 00:04:48,440 --> 00:04:49,280 Oh yeah. 142 00:04:49,280 --> 00:04:51,520 That could wreak havoc on any surface infrastructure. 143 00:04:51,520 --> 00:04:53,280 So a bit of a fixer upper planet. 144 00:04:53,280 --> 00:04:54,320 It needs a little bit of work. 145 00:04:54,320 --> 00:04:55,160 It needs some work. 146 00:04:55,160 --> 00:04:55,980 Yeah. 147 00:04:55,980 --> 00:04:57,840 But what about thinking outside the planet box entirely? 148 00:04:57,840 --> 00:04:58,680 Yeah. 149 00:04:58,680 --> 00:05:01,480 Your research also delves into the potential 150 00:05:01,480 --> 00:05:04,520 of space stations as colonization hubs. 151 00:05:04,520 --> 00:05:06,340 Is that a serious contender? 152 00:05:06,340 --> 00:05:07,180 Absolutely. 153 00:05:07,180 --> 00:05:10,640 Space stations offer some intriguing advantages. 154 00:05:10,640 --> 00:05:11,480 Okay. 155 00:05:11,480 --> 00:05:15,700 Imagine modular habitats like the lunar gateway. 156 00:05:15,700 --> 00:05:18,240 But much larger orbiting Earth. 157 00:05:18,240 --> 00:05:19,080 Yeah. 158 00:05:19,080 --> 00:05:22,920 Or even strategically placed near resource rich asteroids. 159 00:05:22,920 --> 00:05:23,760 I like it. 160 00:05:23,760 --> 00:05:25,240 They could offer a more controlled environment. 161 00:05:25,240 --> 00:05:26,080 Okay. 162 00:05:26,080 --> 00:05:28,320 Free from the constraints of a planet surface. 163 00:05:28,320 --> 00:05:29,560 Sounds pretty futuristic. 164 00:05:29,560 --> 00:05:30,560 A little bit, yeah. 165 00:05:30,560 --> 00:05:32,380 But I imagine even space stations come 166 00:05:32,380 --> 00:05:33,580 with their own set of headaches. 167 00:05:33,580 --> 00:05:34,420 Oh, of course. 168 00:05:34,420 --> 00:05:36,200 The biggest challenge is resource dependency. 169 00:05:36,200 --> 00:05:37,040 Okay. 170 00:05:37,040 --> 00:05:38,960 Space stations would require constant resupply 171 00:05:38,960 --> 00:05:41,280 from Earth for the foreseeable future. 172 00:05:41,280 --> 00:05:42,160 Right. 173 00:05:42,160 --> 00:05:43,000 Think about it. 174 00:05:43,000 --> 00:05:43,820 Yeah. 175 00:05:43,820 --> 00:05:47,160 Water, air, spare parts. 176 00:05:47,160 --> 00:05:48,000 Yeah. 177 00:05:48,000 --> 00:05:49,920 Everything would need to be shipped from Earth. 178 00:05:49,920 --> 00:05:50,760 Wow. 179 00:05:50,760 --> 00:05:53,600 Making it logistically and economically challenging. 180 00:05:53,600 --> 00:05:54,440 Right. 181 00:05:54,440 --> 00:05:55,260 At least initially. 182 00:05:55,260 --> 00:05:56,100 Yeah. 183 00:05:56,100 --> 00:05:58,120 So maybe more of a stepping stone 184 00:05:58,120 --> 00:06:00,240 to full blown colonization. 185 00:06:00,240 --> 00:06:01,080 I think so. 186 00:06:01,080 --> 00:06:02,160 And a permanent solution. 187 00:06:02,160 --> 00:06:03,200 Right. 188 00:06:03,200 --> 00:06:05,440 Your sources also mentioned asteroids themselves 189 00:06:05,440 --> 00:06:06,600 as potential sites. 190 00:06:06,600 --> 00:06:07,440 They do. 191 00:06:07,440 --> 00:06:09,000 I'm picturing something out of The Expanse. 192 00:06:09,000 --> 00:06:09,960 Oh yeah, good show. 193 00:06:09,960 --> 00:06:11,120 How realistic is that? 194 00:06:11,120 --> 00:06:13,960 Well, asteroids are like the cosmic wild card. 195 00:06:13,960 --> 00:06:14,800 Okay. 196 00:06:14,800 --> 00:06:17,680 Full of valuable minerals like platinum and nickel. 197 00:06:17,680 --> 00:06:18,520 Uh-huh. 198 00:06:18,520 --> 00:06:20,560 Some even contain water ice. 199 00:06:20,560 --> 00:06:21,400 Right. 200 00:06:21,400 --> 00:06:23,440 Which could be converted into rocket fuel. 201 00:06:23,440 --> 00:06:24,280 Okay. 202 00:06:24,280 --> 00:06:25,820 Turning them into refueling stations 203 00:06:25,820 --> 00:06:27,600 for deeper space exploration. 204 00:06:27,600 --> 00:06:28,440 Right. 205 00:06:28,440 --> 00:06:30,400 But building habitats on asteroids. 206 00:06:30,400 --> 00:06:32,920 That's where things get really tricky. 207 00:06:32,920 --> 00:06:33,840 And I can imagine. 208 00:06:33,840 --> 00:06:35,200 No gravity to speak of. 209 00:06:35,200 --> 00:06:36,040 Right. 210 00:06:36,040 --> 00:06:38,400 Constantly bombarded by micrometeoroids. 211 00:06:38,400 --> 00:06:39,240 Uh-huh. 212 00:06:39,240 --> 00:06:41,760 Not to mention the challenge of anchoring anything 213 00:06:41,760 --> 00:06:43,760 to a spinning rock in space. 214 00:06:43,760 --> 00:06:44,720 That too. 215 00:06:44,720 --> 00:06:46,600 Sounds like a recipe for disaster. 216 00:06:46,600 --> 00:06:49,080 It's definitely not for the faint of heart. 217 00:06:49,080 --> 00:06:49,920 No. 218 00:06:49,920 --> 00:06:52,720 Your research highlights these immense engineering challenges. 219 00:06:52,720 --> 00:06:53,560 Yeah. 220 00:06:53,560 --> 00:06:55,440 But it also suggests that asteroids 221 00:06:55,440 --> 00:06:58,080 could become crucial resource hubs. 222 00:06:58,080 --> 00:06:58,920 Okay. 223 00:06:58,920 --> 00:07:01,940 Even if permanent habitation remains a distant goal. 224 00:07:01,940 --> 00:07:04,000 So we've got our potential locations. 225 00:07:04,000 --> 00:07:04,840 We do. 226 00:07:04,840 --> 00:07:07,240 Each with its own set of perks and problems. 227 00:07:07,240 --> 00:07:08,660 But let's say we pick a spot 228 00:07:08,660 --> 00:07:11,440 and decide to go all in on space colonization. 229 00:07:11,440 --> 00:07:13,840 What kind of tech are we gonna need to pull this off? 230 00:07:13,840 --> 00:07:14,680 Yeah. 231 00:07:14,680 --> 00:07:17,680 Because I'm guessing duct tape and a prayer won't cut it. 232 00:07:17,680 --> 00:07:18,520 I don't think so. 233 00:07:18,520 --> 00:07:19,340 No. 234 00:07:19,340 --> 00:07:22,320 That's where the truly mind blowing aspects 235 00:07:22,320 --> 00:07:23,440 of your research come in. 236 00:07:23,440 --> 00:07:24,280 Right. 237 00:07:24,280 --> 00:07:25,520 We're talking about a whole suite of technologies. 238 00:07:25,520 --> 00:07:27,000 Some already in development. 239 00:07:27,000 --> 00:07:27,840 Right. 240 00:07:27,840 --> 00:07:29,640 Others still in the realm of science fiction. 241 00:07:29,640 --> 00:07:30,480 Yeah. 242 00:07:30,480 --> 00:07:31,960 But one thing is clear. 243 00:07:31,960 --> 00:07:32,800 Okay. 244 00:07:32,800 --> 00:07:35,360 Life support systems are absolutely paramount. 245 00:07:35,360 --> 00:07:36,200 Life support. 246 00:07:36,200 --> 00:07:37,020 Yeah. 247 00:07:37,020 --> 00:07:38,040 That sounds pretty basic. 248 00:07:38,040 --> 00:07:38,880 I don't care. 249 00:07:38,880 --> 00:07:40,640 But I bet it gets complicated fast 250 00:07:40,640 --> 00:07:42,360 when you're talking about living in space. 251 00:07:42,360 --> 00:07:43,200 Very fast. 252 00:07:43,200 --> 00:07:44,360 What are the key ingredients 253 00:07:44,360 --> 00:07:47,640 for keeping humans alive off world? 254 00:07:47,640 --> 00:07:51,500 Well, the sources all emphasize closed loop systems 255 00:07:51,500 --> 00:07:52,580 as the Holy Grail. 256 00:07:52,580 --> 00:07:53,420 Okay. 257 00:07:53,420 --> 00:07:55,960 Imagine a miniature earth in a habitat 258 00:07:55,960 --> 00:07:59,880 where air, water and waste are constantly recycled 259 00:07:59,880 --> 00:08:00,960 and regenerated. 260 00:08:00,960 --> 00:08:01,800 Wow. 261 00:08:01,800 --> 00:08:04,720 We can't afford to constantly ship supplies from earth. 262 00:08:04,720 --> 00:08:05,560 Right. 263 00:08:05,560 --> 00:08:09,280 Learning to live off the land, so to speak, is essential. 264 00:08:09,280 --> 00:08:11,920 So it's like creating a self-sustaining ecosystem 265 00:08:11,920 --> 00:08:12,740 in a bottle. 266 00:08:12,740 --> 00:08:13,580 Pretty much, yeah. 267 00:08:13,580 --> 00:08:15,200 Are there any examples of this kind 268 00:08:15,200 --> 00:08:17,600 of technology actually working? 269 00:08:17,600 --> 00:08:19,540 One example that pops up in your research 270 00:08:19,540 --> 00:08:21,480 is NASA's MOXIE experiment. 271 00:08:21,480 --> 00:08:22,320 Okay. 272 00:08:22,320 --> 00:08:24,840 Which stands for Mars Oxygen Institute 273 00:08:24,840 --> 00:08:26,880 Resource Utilization Experiment. 274 00:08:26,880 --> 00:08:27,700 Okay. 275 00:08:27,700 --> 00:08:29,020 I'm gonna need you to break that down for me. 276 00:08:29,020 --> 00:08:31,960 Basically, it's designed to extract oxygen 277 00:08:31,960 --> 00:08:33,640 from the Martian atmosphere. 278 00:08:33,640 --> 00:08:34,480 Oh, okay. 279 00:08:34,480 --> 00:08:36,240 And then it can be stepped toward breathable air 280 00:08:36,240 --> 00:08:37,240 on another planet. 281 00:08:37,240 --> 00:08:39,600 So we could potentially breathe Martian air one day. 282 00:08:39,600 --> 00:08:40,440 Potentially air. 283 00:08:40,440 --> 00:08:41,280 That's pretty amazing. 284 00:08:41,280 --> 00:08:42,100 It is. 285 00:08:42,100 --> 00:08:44,160 But I imagine oxygen is just the tip of the iceberg 286 00:08:44,160 --> 00:08:45,520 when it comes to life support, right? 287 00:08:45,520 --> 00:08:46,360 Exactly. 288 00:08:46,360 --> 00:08:47,180 Yeah. 289 00:08:47,180 --> 00:08:49,240 Your research highlights the interconnectedness 290 00:08:49,240 --> 00:08:51,100 of all these systems. 291 00:08:51,100 --> 00:08:53,800 Growing food, purifying water. 292 00:08:53,800 --> 00:08:54,640 Right. 293 00:08:54,640 --> 00:08:55,720 Managing waste. 294 00:08:55,720 --> 00:08:56,560 Yeah. 295 00:08:56,560 --> 00:08:57,920 Even creating artificial gravity. 296 00:08:57,920 --> 00:08:58,760 Okay. 297 00:08:58,760 --> 00:09:02,240 All of these elements will need to work together seamlessly 298 00:09:02,240 --> 00:09:04,400 to support human life in the long term. 299 00:09:04,400 --> 00:09:05,920 It sounds like a massive undertaking. 300 00:09:05,920 --> 00:09:06,760 It is, yeah. 301 00:09:06,760 --> 00:09:08,200 But before we get into the nitty gritty 302 00:09:08,200 --> 00:09:10,640 of space farming and waste recycling. 303 00:09:10,640 --> 00:09:11,480 Sure. 304 00:09:11,480 --> 00:09:14,600 There's another big concern I keep thinking about. 305 00:09:14,600 --> 00:09:15,680 Radiation. 306 00:09:15,680 --> 00:09:18,020 How do you protect colonists 307 00:09:18,020 --> 00:09:20,640 from those harmful cosmic rays 308 00:09:20,640 --> 00:09:24,080 and solar flares constantly bombarding space? 309 00:09:24,080 --> 00:09:25,760 That's a crucial challenge. 310 00:09:25,760 --> 00:09:28,860 And your sources explore several approaches. 311 00:09:28,860 --> 00:09:32,620 Shielding habitats with water, regolith, 312 00:09:32,620 --> 00:09:34,840 or even polyethylene is a common theme. 313 00:09:34,840 --> 00:09:35,680 Okay. 314 00:09:35,680 --> 00:09:37,840 Imagine living inside a water tank. 315 00:09:37,840 --> 00:09:38,680 Okay. 316 00:09:38,680 --> 00:09:40,480 Or burying habitats underground. 317 00:09:40,480 --> 00:09:41,320 Right, okay. 318 00:09:41,320 --> 00:09:42,280 To protect against radiation. 319 00:09:42,280 --> 00:09:43,400 Underground habitat. 320 00:09:43,400 --> 00:09:44,280 Potentially, yeah. 321 00:09:44,280 --> 00:09:47,200 So we might be living like mole people on Mars. 322 00:09:47,200 --> 00:09:48,040 Maybe. 323 00:09:48,040 --> 00:09:50,120 I'm not sure that's the glamorous space future 324 00:09:50,120 --> 00:09:50,960 I had in mind. 325 00:09:50,960 --> 00:09:52,900 It might not be the most glamorous, but. 326 00:09:52,900 --> 00:09:54,560 But I guess safety first. 327 00:09:54,560 --> 00:09:55,720 Safety first. 328 00:09:55,720 --> 00:09:58,160 What about the energy to power all of this? 329 00:09:58,160 --> 00:09:59,000 Uh-huh. 330 00:09:59,000 --> 00:10:00,040 Where are we gonna get the juice 331 00:10:00,040 --> 00:10:01,840 to run these life support systems, 332 00:10:01,840 --> 00:10:04,200 habitats, and everything else a colony needs? 333 00:10:04,200 --> 00:10:07,280 Well, your research consistently points to solar power 334 00:10:07,280 --> 00:10:09,720 as the most likely primary source, 335 00:10:09,720 --> 00:10:10,800 at least in the early stages. 336 00:10:10,800 --> 00:10:11,640 Okay. 337 00:10:11,640 --> 00:10:13,760 Giant solar arrays could harness 338 00:10:13,760 --> 00:10:15,800 the abundant energy of the sun. 339 00:10:15,800 --> 00:10:16,620 Right. 340 00:10:16,620 --> 00:10:18,780 Particularly in areas with minimal atmosphere 341 00:10:18,780 --> 00:10:19,720 to filter it out. 342 00:10:19,720 --> 00:10:20,560 Okay, that makes sense. 343 00:10:20,560 --> 00:10:21,400 Yeah. 344 00:10:21,400 --> 00:10:24,440 But what about places with long periods of darkness? 345 00:10:24,440 --> 00:10:25,280 Uh-huh. 346 00:10:25,280 --> 00:10:27,600 Like those 14 day lunar nights we talked about earlier. 347 00:10:27,600 --> 00:10:28,440 Yeah. 348 00:10:28,440 --> 00:10:30,840 Are we gonna be sitting in the dark half the time? 349 00:10:30,840 --> 00:10:33,200 That's where energy storage comes in. 350 00:10:33,200 --> 00:10:34,400 Advanced batteries. 351 00:10:34,400 --> 00:10:35,240 Uh-huh. 352 00:10:35,240 --> 00:10:36,060 Fuel cells. 353 00:10:36,060 --> 00:10:36,900 Okay. 354 00:10:36,900 --> 00:10:38,840 Even potentially small scale nuclear reactors 355 00:10:38,840 --> 00:10:40,200 are all on the table. 356 00:10:40,200 --> 00:10:41,040 Wow. 357 00:10:41,040 --> 00:10:44,040 The key is finding a reliable mix of energy sources. 358 00:10:44,040 --> 00:10:44,880 Right. 359 00:10:44,880 --> 00:10:46,000 To provide continuous power 360 00:10:46,000 --> 00:10:47,960 no matter where the colony is located. 361 00:10:47,960 --> 00:10:48,800 Right. 362 00:10:48,800 --> 00:10:50,420 Because nobody wants to live in a space colony 363 00:10:50,420 --> 00:10:51,560 with rolling blackouts. 364 00:10:51,560 --> 00:10:52,800 No, definitely not. 365 00:10:52,800 --> 00:10:54,120 Speaking of places to live. 366 00:10:54,120 --> 00:10:54,960 Yeah. 367 00:10:54,960 --> 00:10:56,880 Let's talk about those habitats themselves. 368 00:10:56,880 --> 00:10:57,720 Okay. 369 00:10:57,720 --> 00:10:59,720 Building anything in space is a challenge. 370 00:10:59,720 --> 00:11:00,560 Uh-huh. 371 00:11:00,560 --> 00:11:02,640 These structures need to withstand 372 00:11:02,640 --> 00:11:05,440 extreme temperatures, radiation. 373 00:11:05,440 --> 00:11:06,280 Right. 374 00:11:06,280 --> 00:11:08,880 And even the occasional micrometeoroid strike. 375 00:11:08,880 --> 00:11:09,720 Yep. 376 00:11:09,720 --> 00:11:11,240 How are we gonna build structures 377 00:11:11,240 --> 00:11:14,280 that are both robust and comfortable? 378 00:11:14,280 --> 00:11:16,360 That's where 3D printing comes in. 379 00:11:16,360 --> 00:11:17,200 Okay. 380 00:11:17,200 --> 00:11:20,520 Your research points to this technology as a game changer. 381 00:11:20,520 --> 00:11:21,360 Right. 382 00:11:21,360 --> 00:11:24,240 Imagine using robots to 3D print 383 00:11:24,240 --> 00:11:26,520 entire habitats out of local materials. 384 00:11:26,520 --> 00:11:27,360 Okay. 385 00:11:27,360 --> 00:11:29,640 Like lunar regolith or Martian soil. 386 00:11:29,640 --> 00:11:30,480 Yeah. 387 00:11:30,480 --> 00:11:33,200 We need to haul heavy construction materials from Earth. 388 00:11:33,200 --> 00:11:34,040 Right. 389 00:11:34,040 --> 00:11:36,080 Just scoop up what's already there and start printing. 390 00:11:36,080 --> 00:11:38,640 So we could be living in houses made of moon dust. 391 00:11:38,640 --> 00:11:39,920 Essentially, yeah. 392 00:11:39,920 --> 00:11:42,320 That's both futuristic and kind of poetic. 393 00:11:42,320 --> 00:11:43,440 I think so, yeah. 394 00:11:43,440 --> 00:11:45,640 But 3D printing takes time, right? 395 00:11:45,640 --> 00:11:46,480 It does. 396 00:11:46,480 --> 00:11:48,560 What if we need to deploy habitats quickly? 397 00:11:48,560 --> 00:11:49,400 Yeah. 398 00:11:49,400 --> 00:11:50,560 In an emergency situation. 399 00:11:50,560 --> 00:11:52,000 For rapid deployment. 400 00:11:52,000 --> 00:11:52,840 Yeah. 401 00:11:52,840 --> 00:11:54,880 Inflatable habitats are another option. 402 00:11:54,880 --> 00:11:55,720 Inflatable. 403 00:11:55,720 --> 00:11:56,560 Yeah. 404 00:11:56,560 --> 00:11:57,380 Okay. 405 00:11:57,380 --> 00:11:59,320 These are basically giant high-tech balloons. 406 00:11:59,320 --> 00:12:00,160 Oh. 407 00:12:00,160 --> 00:12:01,600 That can be packed up small. 408 00:12:01,600 --> 00:12:02,440 Right. 409 00:12:02,440 --> 00:12:03,280 Launched into space. 410 00:12:03,280 --> 00:12:04,100 Yeah. 411 00:12:04,100 --> 00:12:05,440 And then inflated on-site. 412 00:12:05,440 --> 00:12:06,280 Okay. 413 00:12:06,280 --> 00:12:07,100 Instant housing. 414 00:12:07,100 --> 00:12:08,120 Okay, now we're talking. 415 00:12:08,120 --> 00:12:08,960 Now we're talking. 416 00:12:08,960 --> 00:12:10,960 It's starting to feel like we have the pieces in place 417 00:12:10,960 --> 00:12:12,480 to build a home in space. 418 00:12:12,480 --> 00:12:13,840 It's starting to come together. 419 00:12:13,840 --> 00:12:17,520 But there's one big question we haven't addressed yet. 420 00:12:17,520 --> 00:12:18,420 What's that? 421 00:12:18,420 --> 00:12:19,260 Transportation. 422 00:12:19,260 --> 00:12:20,080 Uh. 423 00:12:20,080 --> 00:12:21,560 How are we gonna get all this stuff 424 00:12:21,560 --> 00:12:23,520 and all these people off Earth 425 00:12:23,520 --> 00:12:25,520 and out to these colonies in the first place? 426 00:12:25,520 --> 00:12:26,360 Right. 427 00:12:26,360 --> 00:12:27,720 Because right now, space travel 428 00:12:27,720 --> 00:12:30,120 is basically a billionaire's playground. 429 00:12:30,120 --> 00:12:31,280 It is expensive, yeah. 430 00:12:31,280 --> 00:12:32,120 Yeah. 431 00:12:32,120 --> 00:12:32,960 That's the elephant in the room. 432 00:12:32,960 --> 00:12:33,780 Yeah. 433 00:12:33,780 --> 00:12:35,320 And your research doesn't shy away 434 00:12:35,320 --> 00:12:37,140 from the immense cost and complexity 435 00:12:37,140 --> 00:12:38,320 of space transportation. 436 00:12:38,320 --> 00:12:39,160 Right. 437 00:12:39,160 --> 00:12:41,760 But it also highlights some exciting developments. 438 00:12:41,760 --> 00:12:42,580 Okay. 439 00:12:42,580 --> 00:12:46,060 Particularly in the area of reusable

Okay. 444 00:12:49,500 --> 00:12:50,960 Isn't that what companies like SpaceX are working on? 445 00:12:50,960 --> 00:12:51,800 Exactly. 446 00:12:51,800 --> 00:12:54,680 SpaceX's Starship program is a prime example. 447 00:12:54,680 --> 00:12:55,520 Okay. 448 00:12:55,520 --> 00:12:57,280 Imagine a spacecraft that can take 449 00:12:57,280 --> 00:12:59,720 hundreds of people to Mars and back. 450 00:12:59,720 --> 00:13:00,560 Wow. 451 00:13:00,560 --> 00:13:03,320 Landing and relaunching like a giant space airplane. 452 00:13:03,320 --> 00:13:04,160 Okay. 453 00:13:04,160 --> 00:13:04,980 If successful. 454 00:13:04,980 --> 00:13:05,820 Yeah. 455 00:13:05,820 --> 00:13:09,080 It could dramatically reduce the cost per passenger. 456 00:13:09,080 --> 00:13:09,900 Right. 457 00:13:09,900 --> 00:13:11,400 Making space travel more accessible. 458 00:13:11,400 --> 00:13:12,220 Yeah. 459 00:13:12,220 --> 00:13:13,520 To a wider range of people. 460 00:13:13,520 --> 00:13:14,920 That would be a game changer. 461 00:13:14,920 --> 00:13:15,760 Big time. 462 00:13:15,760 --> 00:13:17,720 But even with reusable spacecraft, 463 00:13:17,720 --> 00:13:19,920 those trips are still gonna take months, 464 00:13:19,920 --> 00:13:21,080 if not longer. 465 00:13:21,080 --> 00:13:21,920 Right. 466 00:13:21,920 --> 00:13:25,240 Is there any hope for faster travel times in the future? 467

00:13:28,680 --> 00:13:29,880 cooped up in a spaceship? 472 00:13:29,880 --> 00:13:30,720 Right. 473 00:13:30,720 --> 00:13:33,440 Eating freeze dried food and staring out the window. 474 00:13:33,440 --> 00:13:35,360 It's not the most exciting prospect. 475 00:13:35,360 --> 00:13:36,200 No. 476 00:13:36,200 --> 00:13:37,360 For shorter travel times, 477 00:13:37,360 --> 00:13:40,480 your research dives into some truly wild concepts 478 00:13:40,480 --> 00:13:42,460 like nuclear propulsion. 479 00:13:42,460 --> 00:13:43,300 Nuclear propulsion. 480 00:13:43,300 --> 00:13:44,140 Yeah. 481 00:13:44,140 --> 00:13:44,960 Yeah. 482 00:13:44,960 --> 00:13:47,400 Now this is still very much in the theoretical stage 483 00:13:47,400 --> 00:13:50,720 with all sorts of technical and safety hurdles to overcome. 484 00:13:50,720 --> 00:13:51,540 Of course. 485 00:13:51,540 --> 00:13:53,600 But the potential is there 486 00:13:53,600 --> 00:13:56,920 to significantly shorten travel times to Mars and beyond. 487 00:13:56,920 --> 00:13:57,760 Okay. 488 00:13:57,760 --> 00:13:59,440 Maybe even opening up the possibility 489 00:13:59,440 --> 00:14:01,300 of interstellar travel one day. 490 00:14:01,300 --> 00:14:02,440 Whoa. 491 00:14:02,440 --> 00:14:03,640 Interstellar travel. 492 00:14:03,640 --> 00:14:04,480 Oh, it's out there. 493 00:14:04,480 --> 00:14:06,080 That's getting a bit ahead of ourselves, isn't it? 494 00:14:06,080 --> 00:14:06,920 It might be. 495 00:14:06,920 --> 00:14:08,720 We haven't even figured out how to live on Mars yet. 496 00:14:08,720 --> 00:14:09,560 Right. 497 00:14:09,560 --> 00:14:11,720 And now we're talking about visiting other star systems. 498 00:14:11,720 --> 00:14:12,800 Baby steps. 499 00:14:12,800 --> 00:14:14,000 I love

challenge. 503 00:14:20,700 --> 00:14:22,800 Actually establishing a colony. 504 00:14:22,800 --> 00:14:23,640 Sure. 505 00:14:23,640 --> 00:14:26,120 How do we go from a few astronauts planting a flag 506 00:14:26,120 --> 00:14:29,640 to a thriving self-sustaining society in space? 507 00:14:29,640 --> 00:14:31,080 That's where things get really interesting. 508 00:14:31,080 --> 00:14:31,920 Okay. 509 00:14:31,920 --> 00:14:33,680 We'll need to delve into the step-by-step process 510 00:14:33,680 --> 00:14:35,400 of building a space colony. 511 00:14:35,400 --> 00:14:36,240 Okay. 512 00:14:36,240 --> 00:14:37,580 From sending robotic pioneers 513 00:14:37,580 --> 00:14:40,340 to establishing the first human outposts 514 00:14:40,340 --> 00:14:44,120 and eventually to creating a new branch of civilization 515 00:14:44,120 --> 00:14:44,960 among the stars. 516 00:14:44,960 --> 00:14:45,800 I like it. 517 00:14:45,800 --> 00:14:48,880 But that's a conversation for part two of our deep dive. 518 00:14:48,880 --> 00:14:50,760 You've definitely piqued my curiosity. 519 00:14:50,760 --> 00:14:51,600 But. 520 00:14:51,600 --> 00:14:53,240 I can't wait to explore those next steps. 521 00:14:53,240 --> 00:14:54,300 I can't wait either. 522 00:14:54,300 --> 00:14:56,120 But for now, let's give our listeners a chance 523 00:14:56,120 --> 00:14:58,240 to digest all this amazing information. 524 00:14:58,240 --> 00:14:59,580 Yeah, sounds good. 525 00:14:59,580 --> 00:15:01,040 We'll be back soon with part two 526 00:15:01,040 --> 00:15:03,360 of our deep dive into

we actually go. 537 00:15:19,760 --> 00:15:22,680 From a few astronauts on Mars 538 00:15:22,680 --> 00:15:25,200 to a full blown Martian colony. 539 00:15:25,200 --> 00:15:27,000 Right, because planting a flag is one thing. 540 00:15:27,000 --> 00:15:27,820 Yeah. 541 00:15:27,820 --> 00:15:32,000 But building a society that can thrive for generations, 542 00:15:32,000 --> 00:15:34,080 that's a whole different level of challenge. 543 00:15:34,080 --> 00:15:34,920 Definitely. 544 00:15:34,920 --> 00:15:36,680 Your research seems to approach this 545 00:15:36,680 --> 00:15:39,320 like a multi-stage rocket. 546 00:15:39,320 --> 00:15:40,160 Okay. 547 00:15:40,160 --> 00:15:42,040 Starting with robots doing the heavy lifting. 548 00:15:42,040 --> 00:15:43,440 That's a great analogy. 549 00:15:43,440 --> 00:15:44,260 Yeah. 550 00:15:44,260 --> 00:15:46,040 Several sources emphasize the importance 551 00:15:46,040 --> 00:15:47,620 of robotic precursors. 552 00:15:47,620 -->

job? 573 00:16:17,880 --> 00:16:20,160 Is it just like humans arrive 574 00:16:20,160 --> 00:16:22,560 and move into their prefab space houses? 575 00:16:22,560 --> 00:16:23,920 Not quite that simple. 576 00:16:23,920 --> 00:16:24,760 Okay. 577 00:16:24,760 --> 00:16:27,000 Your research suggests a more nuanced approach. 578 00:16:27,000 --> 00:16:27,840 Okay. 579 00:16:27,840 --> 00:16:30,560 Using the moon as a crucial stepping stone. 580 00:16:30,560 --> 00:16:31,560 Oh, interesting. 581 00:16:31,560 --> 00:16:33,400 Imagine a lunar base. 582 00:16:33,400 --> 00:16:34,240 Okay. 583 00:16:34,240 --> 00:16:36,000 Not just as a research outpost. 584 00:16:36,000 --> 00:16:36,840 Yeah. 585 00:16:36,840 --> 00:16:38,680 But as a full scale testing ground. 586 00:16:38,680 --> 00:16:39,520 Okay. 587 00:16:39,520 --> 00:16:41,080 For the technologies and systems 588 00:16:41,080 --> 00:16:43,960 needed for long term Martian colonization. 589 00:16:43,960 --> 00:16:47,500 So we're talking about like a lunar proving ground. 590 00:16:47,500 --> 00:16:48,340 Pretty much. 591 00:16:48,340 --> 00:16:51,920 So we work out the kinks in life support. 592 00:16:51,920 --> 00:16:52,760 Yep. 593 00:16:52,760 --> 00:16:54,640 Energy generation, food production. 594 00:16:54,640 --> 00:16:55,480 Mm-hmm. 595 00:16:55,480 --> 00:16:56,720 All those essential elements. 596 00:16:56,720 --> 00:16:57,560 Exactly. 597 00:16:57,560 --> 00:16:59,960 Before we try to replicate them on a much more distant. 598 00:16:59,960 --> 00:17:00,800 Right. 599 00:17:00,800 --> 00:17:02,240 And unforgiving planet like Mars. 600 00:17:02,240 --> 00:17:03,160 It's a good strategy. 601 00:17:03,160 --> 00:17:04,000 Yeah. 602 00:17:04,000 --> 00:17:04,840 Much less risky. 603 00:17:04,840 --> 00:17:05,760 It is a smart strategy. 604 00:17:05,760 --> 00:17:06,600 Yeah. 605 00:17:06,600 --> 00:17:07,420 Yeah. 606 00:17:07,420 --> 00:17:09,160 But I'm curious about those early Martian habitats. 607 00:17:09,160 --> 00:17:10,000 Uh-huh. 608 00:17:10,000 --> 00:17:11,320 We're talking about underground bunkers. 609 00:17:11,320 --> 00:17:12,320 I don't think so, no. 610 00:17:12,320 --> 00:17:15,960 Or something a bit more, shall we say, aspirational. 611 00:17:15,960 --> 00:17:19,120 Your sources paint a picture of modular habitats. 612 00:17:19,120 --> 00:17:19,960 Okay. 613 00:17:19,960 --> 00:17:23,600 Initially quite small and reliant on resupply from Earth. 614 00:17:23,600 --> 00:17:24,440 Okay. 615 00:17:24,440 --> 00:17:26,520 Think of them like interplanetary camping trips. 616 00:17:26,520 --> 00:17:28,800 But gradually evolving into larger, 617 00:17:28,800 --> 00:17:30,560 more self-sufficient communities. 618 00:17:30,560 --> 00:17:31,400 Yeah. 619 00:17:31,400 --> 00:17:33,960 As local resource extraction and production ramp up. 620 00:17:33,960 --> 00:17:37,160 So a gradual transition from camping to homesteading. 621 00:17:37,160 --> 00:17:38,000 Yeah, I like that. 622 00:17:38,000 --> 00:17:39,440 With Martian grown food on the table. 623 00:17:39,440 --> 00:17:40,280 Right. 624 00:17:40,280 --> 00:17:41,680 And Martian made tools in hand. 625 00:17:41,680 --> 00:17:42,520 Exactly. 626 00:17:42,520 --> 00:17:43,520 It's an inspiring vision. 627 00:17:43,520 --> 00:17:44,360 Yeah. 628 00:17:44,360 -->

For sure. 632 00:17:49,000 --> 00:17:50,080 Starting with sustainability. 633 00:17:50,080 --> 00:17:50,920 Yeah. 634 00:17:50,920 --> 00:17:53,360 How long will it realistically take 635 00:17:53,360 --> 00:17:56,480 for these colonies to become truly self-sufficient? 636 00:17:56,480 --> 00:17:57,320 Right. 637 00:17:57,320 --> 00:18:00,080 Where they're no longer dependent on Earth for survival. 638 00:18:00,080 --> 00:18:01,760 That's the million dollar question. 639 00:18:01,760 --> 00:18:02,600 It is. 640 00:18:02,600 --> 00:18:04,880 And your sources offer a range of perspectives. 641 00:18:04,880 --> 00:18:05,720 Okay. 642 00:18:05,720 --> 00:18:06,840 Some optimistic. 643 00:18:06,840 --> 00:18:07,680 Sure. 644 00:18:07,680 --> 00:18:08,520 Some more cautious. 645 00:18:08,520 --> 00:18:09,340 Right. 646 00:18:09,340 --> 00:18:11,880 The consensus seems to be that it will take decades. 647 00:18:11,880 --> 00:18:12,720 Wow. 648 00:18:12,720 --> 00:18:13,560 If not centuries. 649 00:18:13,560 --> 00:18:14,400 Centuries. 650 00:18:14,400 --> 00:18:15,240 Yeah. 651 00:18:15,240 --> 00:18:17,080 To get true self-sufficiency. 652 00:18:17,080 --> 00:18:17,920 Yeah. 653 00:18:17,920 --> 00:18:18,740 It's a long process. 654 00:18:18,740 --> 00:18:20,280 That's a long time to be relying 655 00:18:20,280 --> 00:18:22,000 on care packages from Earth. 656 00:18:22,000 --> 00:18:23,400 Yeah, it's a logistical challenge. 657 00:18:23,400 --> 00:18:24,240 Yep. 658 00:18:24,240 --> 00:18:25,960 And it's not just about the resources. 659 00:18:25,960 --> 00:18:26,800 Right. 660 00:18:26,800 --> 00:18:27,620 Yeah. 661 00:18:27,620 --> 00:18:28,460 We're also talking about the human factor. 662 00:18:28,460 --> 00:18:29,300 Absolutely. 663 00:18:29,300 --> 00:18:31,520 How do we ensure the mental and physical well-being 664 00:18:31,520 --> 00:18:32,360 of people. 665 00:18:32,360 --> 00:18:33,200 Yeah. 666 00:18:33,200 --> 00:18:37,000 Living in these isolated, confined environments. 667 00:18:37,000 --> 00:18:38,720 Generations removed from Earth. 668 00:18:38,720 --> 00:18:40,320 That's where the psychological 669 00:18:40,320 --> 00:18:43,160 and physiological adaptation challenges come in. 670 00:18:43,160 --> 00:18:44,000 Right. 671 00:18:44,000 --> 00:18:45,920 The research highlights the potential risks. 672 00:18:45,920 --> 00:18:46,760 Okay. 673 00:18:46,760 --> 00:18:50,280 Of long duration space travel and off-world living. 674 00:18:50,280 --> 00:18:51,120 Okay. 675 00:18:51,120 --> 00:18:52,080 Radiation exposure. 676 00:18:52,080 --> 00:18:52,920 Uh-huh. 677 00:18:52,920 --> 00:18:55,120 Bone density loss due to lower gravity. 678 00:18:55,120 --> 00:18:55,960 Right. 679 00:18:55,960 --> 00:18:58,720 Even the potential for unique Martian-born diseases. 680 00:18:58,720 --> 00:18:59,560 Wow. 681 00:18:59,560 --> 00:19:02,680 These are all factors that will need to be addressed. 682 00:19:02,680 --> 00:19:03,640 It makes you wonder. 683 00:19:03,640 --> 00:19:04,480 Yeah. 684 00:19:04,480 --> 00:19:07,200 Will future generations born on Mars 685 00:19:07,200 --> 00:19:08,800 even be able to visit Earth? 686 00:19:08,800 --> 00:19:09,680 That's a good question. 687 00:19:09,680 --> 00:19:11,800 Will they be too physiologically different. 688 00:19:11,800 --> 00:19:12,640 Right. 689 00:19:12,640 --> 00:19:14,080 To a lower gravity environment. 690 00:19:14,080 --> 00:19:14,900 It's possible. 691 00:19:14,900 --> 00:19:16,800 It's almost like we're talking about the evolution 692 00:19:16,800 --> 00:19:18,520 of a new human species. 693 00:19:18,520 --> 00:19:19,760 It's a fascinating. 694 00:19:19,760 --> 00:19:20,600 It is. 695 00:19:20,600 --> 00:19:23,200 And somewhat unsettling thought experiment. 696 00:19:23,200 --> 00:19:25,520 Your sources delve into the ethical 697 00:19:25,520 --> 00:19:27,400 and philosophical implications. 698 00:19:27,400 --> 00:19:28,220 Yeah. 699 00:19:28,220 --> 00:19:29,640 Of this potential divergence. 700 00:19:29,640 --> 00:19:30,480 Right. 701 00:19:30,480 --> 00:19:32,080 Questioning what it means to be human. 702 00:19:32,080 --> 00:19:32,920 Uh-huh. 703 00:19:32,920 --> 00:19:34,560 And whether our values and rights. 704 00:19:34,560 --> 00:19:35,400 Yep. 705 00:19:35,400 --> 00:19:37,960 Will translate to a multi-planetary society. 706 00:19:37,960 --> 00:19:38,920 It's a big question. 707 00:19:38,920 --> 00:19:39,960 It is a big question. 708 00:19:39,960 --> 00:19:40,960 Yeah. 709 00:19:40,960 --> 00:19:43,480 But before we get too lost in existential pondering. 710 00:19:43,480 --> 00:19:44,480 Sure. 711 00:19:44,480 --> 00:19:46,100 There's a more immediate concern that 712 00:19:46,100 --> 00:19:48,320 keeps popping up in my mind. 713 00:19:48,320 --> 00:19:49,200 Conflict. 714 00:19:49,200 --> 00:19:49,840 Conflict. 715 00:19:49,840 --> 00:19:50,400 Yeah. 716 00:19:50,400 --> 00:19:52,280 I'm thinking about all those sci-fi stories 717 00:19:52,280 --> 00:19:55,720 where Earth and its colonies end up at odds with each other. 718 00:19:55,720 --> 00:19:56,220 Right. 719 00:19:56,220 --> 00:19:58,640 Fighting over resources or independence. 720 00:19:58,640 --> 00:19:59,140 Yeah. 721 00:19:59,140 --> 00:20:01,040 The classic us versus them scenario. 722 00:20:01,040 --> 00:20:01,640 Exactly. 723 00:20:01,640 --> 00:20:02,140 Yeah. 724 00:20:02,140 --> 00:20:03,840 How realistic is that scenario? 725 00:20:03,840 --> 00:20:06,720 Your research doesn't dismiss the potential for conflict. 726 00:20:06,720 --> 00:20:07,240 OK. 727 00:20:07,240 --> 00:20:09,320 After all, human history is full of examples. 728 00:20:09,320 --> 00:20:09,820 Yeah. 729 00:20:09,820 --> 00:20:12,120 Of groups competing for power and resources. 730 00:20:12,120 --> 00:20:12,920 It's true. 731 00:20:12,920 --> 00:20:15,280 The question is, can we learn from those mistakes? 732 00:20:15,280 --> 00:20:15,780 Right. 733 00:20:15,780 --> 00:20:19,640 And create a framework for peaceful coexistence 734 00:20:19,640 --> 00:20:21,600 and cooperation in space. 735 00:20:21,600 --> 00:20:22,520 That's the hope. 736 00:20:22,520 --> 00:20:23,240 It is. 737 00:20:23,240 --> 00:20:26,200 So how do we prevent those sci-fi discopias 738 00:20:26,200 --> 00:20:27,640 from becoming reality? 739 00:20:27,640 --> 00:20:28,240 Right. 740 00:20:28,240 --> 00:20:31,680 Is it as simple as drawing up some interplanetary treaties 741 00:20:31,680 --> 00:20:33,440 and hoping everyone plays by the rules? 742 00:20:33,440 --> 00:20:34,920 It's definitely not that simple. 743 00:20:34,920 --> 00:20:35,420 Which? 744 00:20:35,420 --> 00:20:37,840 Your research dives into the complexities 745 00:20:37,840 --> 00:20:38,960 of space governance. 746 00:20:38,960 --> 00:20:41,920 It's not just about legal frameworks, 747 00:20:41,920 --> 00:20:46,800 but about building trust, fostering communication, 748 00:20:46,800 --> 00:20:50,240 and establishing mechanisms for conflict resolution that 749 00:20:50,240 --> 00:20:52,360 work across planetary boundaries. 750 00:20:52,360 --> 00:20:54,680 It sounds like we need a whole new field of diplomacy. 751 00:20:54,680 --> 00:20:55,200 Yeah. 752 00:20:55,200 --> 00:20:58,600 Something like interplanetary conflict mediators shuttling 753 00:20:58,600 --> 00:21:01,360 between Earth and Mars to smooth things over. 754 00:21:01,360 --> 00:21:02,440 Interesting. 755 00:21:02,440 --> 00:21:04,520 Maybe we can train dolphins to do it. 756 00:21:04,520 --> 00:21:05,020 Right. 757 00:21:05,020 --> 00:21:06,480 They're supposed to be good communicators. 758 00:21:06,480 --> 00:21:07,680 That's an interesting image. 759 00:21:07,680 --> 00:21:08,180 Yeah. 760 00:21:08,180 --> 00:21:10,840 So I'm not sure how well dolphins would fare in space. 761 00:21:10,840 --> 00:21:11,920 Probably not very well. 762 00:21:11,920 --> 00:21:12,440 No. 763 00:21:12,440 --> 00:21:13,440 The point is well taken. 764 00:21:13,440 --> 00:21:13,940 Yeah. 765 00:21:13,940 --> 00:21:15,720 We need to start thinking seriously 766 00:21:15,720 --> 00:21:19,880 about how we manage relationships, resolve disputes, 767 00:21:19,880 --> 00:21:23,800 and ensure equitable access to resources in a 768 00:21:23,800 --> 00:21:25,160 multi-planetary future. 769 00:21:25,160 --> 00:21:26,760 Yeah, it's a whole new ball game. 770 00:21:26,760 --> 00:21:27,880 It is a whole new ball game. 771 00:21:27,880 --> 00:21:28,400 Yeah. 772 00:21:28,400 --> 00:21:33,220 And I'm realizing this whole space colonization endeavor 773 00:21:33,220 --> 00:21:37,000 is about so much more than just building rockets and habitats. 774 00:21:37,000 --> 00:21:37,560 Right. 775 00:21:37,560 --> 00:21:40,440 It's about redefining our relationship with each other, 776 00:21:40,440 --> 00:21:43,320 with our planet, and with the cosmos itself. 777 00:21:43,320 --> 00:21:44,880 That's a powerful insight. 778 00:21:44,880 --> 00:21:45,400 Yeah. 779 00:21:45,400 --> 00:21:47,720 Space exploration has a way of forcing 780 00:21:47,720 --> 00:21:51,960 us to confront fundamental questions about who we are, 781 00:21:51,960 --> 00:21:55,480 where we belong, and what kind of future we want to create. 782 00:21:55,480 --> 00:21:57,400 It's not just a technological challenge. 783 00:21:57,400 --> 00:21:57,900 Right. 784 00:21:57,900 --> 00:22:01,120 It's a reflection of our values and aspirations. 785 00:22:01,120 --> 00:22:02,600 I like that perspective. 786 00:22:02,600 --> 00:22:04,880 It's not just about escaping Earth. 787 00:22:04,880 --> 00:22:06,600 It's about evolving as a species. 788 00:22:06,600 --> 00:22:07,120 Right. 789 00:22:07,120 --> 00:22:09,880 It's about becoming something more than we are now. 790 00:22:09,880 --> 00:22:10,800 I agree. 791 00:22:10,800 --> 00:22:13,880 And I think that's an idea that can unite people 792 00:22:13,880 --> 00:22:16,200 from all walks of life, regardless 793 00:22:16,200 --> 00:22:17,920 of their background or beliefs. 794 00:22:17,920 --> 00:22:20,680 Space exploration has the potential 795 00:22:20,680 --> 00:22:23,720 to transcend our differences and inspire 796 00:22:23,720 --> 00:22:25,720 a new era of collaboration. 797 00:22:25,720 --> 00:22:26,440 I hope so. 798 00:22:26,440 --> 00:22:27,760 Innovation and hope. 799 00:22:27,760 --> 00:22:28,320 Absolutely. 800 00:22:28,320 --> 00:22:33,320 It's a reminder that we're all part of the same human story. 801 00:22:33,320 --> 00:22:35,560 And that story is just beginning to unfold. 802 00:22:35,560 --> 00:22:37,320 That's a great place to pause for now. 803 00:22:37,320 --> 00:22:37,840 It is. 804 00:22:37,840 --> 00:22:38,880 Yeah. 805 00:22:38,880 --> 00:22:39,920 But we're not done yet. 806 00:22:39,920 --> 00:22:40,440 Right. 807 00:22:40,440 --> 00:22:43,000 Next time on Cosmos in a Pod, we'll 808 00:22:43,000 --> 00:22:46,120 wrap up our deep dive into space colonization. 809 00:22:46,120 --> 00:22:46,720 We will. 810 00:22:46,720 --> 00:22:48,960 By tackling those big ethical questions. 811 00:22:48,960 --> 00:22:49,680 OK. 812 00:22:49,680 --> 00:22:50,720 The potential pitfalls. 813 00:22:50,720 --> 00:22:51,280 Uh-huh. 814 00:22:51,280 --> 00:22:53,600 And the inspiring possibilities that lie ahead. 815 00:22:53,600 --> 00:22:54,760 I'm looking forward to it. 816 00:22:54,760 --> 00:22:56,400 Welcome back to Cosmos in a Pod. 817 00:22:56,400 --> 00:22:57,480 We're back. 818 00:22:57,480 --> 00:23:00,680 We've journeyed from the motivations for leaving Earth 819 00:23:00,680 --> 00:23:03,360 to the challenges of building a new home in space. 820 00:23:03,360 --> 00:23:04,200 Right. 821 00:23:04,200 --> 00:23:06,000 Now in this final part, your research 822 00:23:06,000 --> 00:23:10,720 takes us beyond the nuts and bolts of rockets and habitats 823 00:23:10,720 --> 00:23:13,800 into the territory of ethics, philosophy, 824 00:23:13,800 --> 00:23:16,520 and the very soul of space colonization. 825 00:23:16,520 --> 00:23:17,400 The big question. 826 00:23:17,400 --> 00:23:18,040 Big question. 827 00:23:18,040 --> 00:23:19,560 It's where it gets really interesting. 828 00:23:19,560 --> 00:23:20,320 It does. 829 00:23:20,320 --> 00:23:22,840 What's striking is how your sources don't shy away 830 00:23:22,840 --> 00:23:24,280 from the tough questions. 831 00:23:24,280 --> 00:23:24,800 Right. 832 00:23:24,800 --> 00:23:27,640 They acknowledge that expanding into space 833 00:23:27,640 --> 00:23:29,880 isn't just a technological feat. 834 00:23:29,880 --> 00:23:30,400 Yeah. 835 00:23:30,400 --> 00:23:33,560 It's a mirror reflecting our human values. 836 00:23:33,560 --> 00:23:34,080 Oh, yeah. 837 00:23:34,080 --> 00:23:36,840 The potential for both greatness and folly. 838 00:23:36,840 --> 00:23:38,880 It's easy to get caught up in the excitement 839 00:23:38,880 --> 00:23:40,160 of new frontiers. 840 00:23:40,160 --> 00:23:40,760 Oh, yeah. 841 00:23:40,760 --> 00:23:43,680 But we can't just repeat the mistakes of the past. 842 00:23:43,680 --> 00:23:44,160 No. 843 00:23:44,160 --> 00:23:45,560 We've been there, done that. 844 00:23:45,560 --> 00:23:47,960 So what are these ethical dilemmas 845 00:23:47,960 --> 00:23:49,600 that keep popping up in your research? 846 00:23:49,600 --> 00:23:52,800 Well, one that looms large is the question of ownership. 847 00:23:52,800 --> 00:23:53,320 OK. 848 00:23:53,320 --> 00:23:55,240 Who gets to claim a piece of Mars? 849 00:23:55,240 --> 00:23:55,740 Right. 850 00:23:55,740 --> 00:23:58,320 Is it a first come, first served, free for all? 851 00:23:58,320 --> 00:23:58,960 Right. 852 00:23:58,960 --> 00:24:02,240 Your sources explore various approaches 853 00:24:02,240 --> 00:24:04,920 from strengthening international treaties 854 00:24:04,920 --> 00:24:08,480 to creating entirely new governance structures 855 00:24:08,480 --> 00:24:10,520 for a multi-planetary society. 856 00:24:10,520 --> 00:24:13,640 Right, because the outer space treaty, while a landmark, 857 00:24:13,640 --> 00:24:15,360 it's really groundbreaking at the time. 858 00:24:15,360 --> 00:24:18,440 It was written back when space travel was in its infancy. 859 00:24:18,440 --> 00:24:18,940 Right. 860 00:24:18,940 --> 00:24:19,960 It could be outdated now. 861 00:24:19,960 --> 00:24:21,800 It doesn't really address the complexities 862 00:24:21,800 --> 00:24:25,000 of permanent settlements, resource extraction, 863 00:24:25,000 --> 00:24:27,880 and all the potential conflicts that could arise. 864 00:24:27,880 --> 00:24:28,640 Exactly. 865 00:24:28,640 --> 00:24:32,200 Some experts in your research argue for an updated treaty. 866 00:24:32,200 --> 00:24:32,700 OK. 867 00:24:32,700 --> 00:24:38,200 That clearly defines property rights, resource allocation, 868 00:24:38,200 --> 00:24:40,440 and environmental protection guidelines 869 00:24:40,440 --> 00:24:41,760 for celestial bodies. 870 00:24:41,760 --> 00:24:42,600 Interesting. 871 00:24:42,600 --> 00:24:45,200 Others propose a more radical shift. 872 00:24:45,200 --> 00:24:46,200 OK, like what? 873 00:24:46,200 --> 00:24:48,680 A kind of interplanetary governing body. 874 00:24:48,680 --> 00:24:49,240 Oh, wow. 875 00:24:49,240 --> 00:24:52,240 That represents not just nations, but also 876 00:24:52,240 --> 00:24:55,080 the interests of future space-born generations. 877 00:24:55,080 --> 00:24:57,920 It's almost like we need a cosmic constatation. 878 00:24:57,920 --> 00:24:58,680 I like that. 879 00:24:58,680 --> 00:25:03,200 Laying out the ground rules for a new era of human civilization. 880 00:25:03,200 --> 00:25:05,440 It's a big task, but someone's got to do it. 881 00:25:05,440 --> 00:25:08,720 But even with the best laws in place, 882 00:25:08,720 --> 00:25:10,720 there's still the issue of ensuring 883 00:25:10,720 --> 00:25:15,400 that this expansion into space benefits all of humanity, 884 00:25:15,400 --> 00:25:16,440 not just a select few. 885 00:25:16,440 --> 00:25:18,840 That's where the concept of equity becomes crucial. 886 00:25:18,840 --> 00:25:21,320 Your research is full of cautionary tales 887 00:25:21,320 --> 00:25:24,840 about how space colonization could exacerbate existing 888 00:25:24,840 --> 00:25:27,400 inequalities if we're not careful. 889 00:25:27,400 --> 00:25:30,480 Imagine a future where only the wealthy elite can afford 890 00:25:30,480 --> 00:25:34,240 a one-way ticket to Mars, leaving the rest of humanity 891 00:25:34,240 --> 00:25:36,040 behind on a depleted Earth. 892 00:25:36,040 --> 00:25:39,000 Yeah, that's not a good look. 893 00:25:39,000 --> 00:25:39,960 Not a good look at all. 894 00:25:39,960 --> 00:25:43,080 It's a dystopian scenario that we need to actively avoid. 895 00:25:43,080 --> 00:25:44,040 For sure. 896 00:25:44,040 --> 00:25:47,720 So how do we ensure that space exploration and its benefits 897 00:25:47,720 --> 00:25:51,040 are accessible to everyone, not just a privileged few? 898 00:25:51,040 --> 00:25:54,920 Well, your sources highlight the need for global cooperation 899 00:25:54,920 --> 00:25:57,360 and investment in STEM education. 900 00:25:57,360 --> 00:25:59,320 Particularly in developing countries. 901 00:25:59,320 --> 00:26:01,800 So it's about creating opportunities for everyone. 902 00:26:01,800 --> 00:26:02,440 Exactly. 903 00:26:02,440 --> 00:26:04,480 To participate in this grand adventure. 904 00:26:04,480 --> 00:26:05,280 That's the idea. 905 00:26:05,280 --> 00:26:07,360 Regardless of their background or nationality. 906 00:26:07,360 --> 00:26:07,880 Absolutely. 907 00:26:07,880 --> 00:26:10,160 It's not just about who gets to go to space. 908 00:26:10,160 --> 00:26:13,240 It's about who gets to benefit from the technological 909 00:26:13,240 --> 00:26:16,960 advancements and scientific discoveries that come 910 00:26:16,960 --> 00:26:18,720 from pushing those boundaries. 911 00:26:18,720 --> 00:26:19,360 Exactly. 912 00:26:19,360 --> 00:26:22,920 Space exploration has historically driven innovation 913 00:26:22,920 --> 00:26:25,760 in fields like medicine, materials, science, 914 00:26:25,760 --> 00:26:29,320 and communications with benefits rippling back to Earth. 915 00:26:29,320 --> 00:26:33,040 Imagine the potential for even greater breakthroughs 916 00:26:33,040 --> 00:26:35,480 as we establish a permanent human presence 917 00:26:35,480 --> 00:26:36,640 beyond our planet. 918 00:26:36,640 --> 00:26:38,680 It's like a rising tide that lifts all boats. 919 00:26:38,680 --> 00:26:40,360 I like that analogy. 920 00:26:40,360 --> 00:26:43,920 But along with those exciting possibilities 921 00:26:43,920 --> 00:26:47,040 comes some profound ethical considerations 922 00:26:47,040 --> 00:26:50,000 about our impact on the environments we're entering. 923 00:26:50,000 --> 00:26:54,240 I'm thinking about things like planetary protection, preserving 924 00:26:54,240 --> 00:26:57,160 the pristine beauty of these alien landscapes. 925 00:26:57,160 --> 00:26:57,960 Right. 926 00:26:57,960 --> 00:27:00,240 Even the potential for terraforming. 927 00:27:00,240 --> 00:27:02,320 That's where the conversation gets really interesting. 928 00:27:02,320 --> 00:27:02,840 It does. 929 00:27:02,840 --> 00:27:05,400 Your research delves into the debate 930 00:27:05,400 --> 00:27:08,600 between those who believe we have a moral obligation 931 00:27:08,600 --> 00:27:11,280 to leave these celestial bodies untouched 932 00:27:11,280 --> 00:27:14,640 and those who argue that terraforming is necessary to make 933 00:27:14,640 --> 00:27:16,520 them habitable for humans. 934 00:27:16,520 --> 00:27:17,560 It's a tough one. 935 00:27:17,560 --> 00:27:18,560 It is, yeah. 936 00:27:18,560 --> 00:27:22,160 On the one hand, it feels almost sacrilegious 937 00:27:22,160 --> 00:27:23,960 to alter these ancient landscapes. 938 00:27:23,960 --> 00:27:24,760 I get that. 939 00:27:24,760 --> 00:27:30,360 On the other hand, if we can make Mars more Earth-like, 940 00:27:30,360 --> 00:27:33,320 wouldn't that open up incredible opportunities 941 00:27:33,320 --> 00:27:35,240 for human expansion and flourishing? 942 00:27:35,240 --> 00:27:36,400 There's no easy answer. 943 00:27:36,400 --> 00:27:37,000 No. 944 00:27:37,000 --> 00:27:39,720 And your research reflects that complexity. 945 00:27:39,720 --> 00:27:43,440 It's about finding a balance between our desire 946 00:27:43,440 --> 00:27:47,360 to explore and expand and our responsibility 947 00:27:47,360 --> 00:27:50,840 to be stewards of the cosmos, to preserve 948 00:27:50,840 --> 00:27:54,200 the wonder and beauty of these alien worlds for future 949 00:27:54,200 --> 00:27:55,040 generations. 950 00:27:55,040 --> 00:27:56,120 It's a delicate balance. 951 00:27:56,120 --> 00:27:58,960 It's a reminder that space colonization isn't just 952 00:27:58,960 --> 00:28:01,080 about conquering new frontiers. 953 00:28:01,080 --> 00:28:03,240 It's about evolving as a species, 954 00:28:03,240 --> 00:28:05,720 about taking the best of humanity with us 955 00:28:05,720 --> 00:28:07,200 as we venture into the unknown. 956 00:28:07,200 --> 00:28:09,400 And that's what I find so compelling about the research 957 00:28:09,400 --> 00:28:10,400 you've compiled. 958 00:28:10,400 --> 00:28:13,240 It's not just a dry technical manual. 959 00:28:13,240 --> 00:28:15,480 It's a philosophical exploration of what 960 00:28:15,480 --> 00:28:18,520 it means to be human in a cosmic context. 961 00:28:18,520 --> 00:28:20,320 It challenges us to think bigger. 962 00:28:20,320 --> 00:28:21,080 Yes. 963 00:28:21,080 --> 00:28:25,600 To dream bolder, but also to act with wisdom and compassion. 964 00:28:25,600 --> 00:28:26,120 Absolutely. 965 00:28:26,120 --> 00:28:28,360 As we shape this multi-planetary future. 966 00:28:28,360 --> 00:28:29,760 It's a powerful message. 967 00:28:29,760 --> 00:28:30,260 It is. 968 00:28:30,260 --> 00:28:33,120 And one that I think resonates deeply with our listeners. 969 00:28:33,120 --> 00:28:35,560 We've covered a lot of ground in this deep dive 970 00:28:35,560 --> 00:28:37,160 into space colonization. 971 00:28:37,160 --> 00:28:37,720 We have. 972 00:28:37,720 --> 00:28:41,280 From the practical challenges of building habitats and growing 973 00:28:41,280 --> 00:28:45,680 food on Mars to the profound ethical questions 974 00:28:45,680 --> 00:28:49,920 about ownership, equity, and our responsibility to the cosmos. 975 00:28:49,920 --> 00:28:50,800 Big topics. 976 00:28:50,800 --> 00:28:51,720 Big topics. 977 00:28:51,720 --> 00:28:54,600 But as we wrap up this journey, I'm 978 00:28:54,600 --> 00:28:57,680 left with a sense of awe and excitement 979 00:28:57,680 --> 00:29:00,000 about the possibilities that lie ahead. 980 00:29:00,000 --> 00:29:02,400 It's an incredible time to be alive. 981 00:29:02,400 --> 00:29:02,900 It is. 982 00:29:02,900 --> 00:29:07,040 To witness humanity on the cusp of a new era of exploration 983 00:29:07,040 --> 00:29:08,080 and discovery. 984 00:29:08,080 --> 00:29:11,360 And while there are certainly risks and challenges involved, 985 00:29:11,360 --> 00:29:13,200 the potential rewards are immense. 986 00:29:13,200 --> 00:29:13,800 They are. 987 00:29:13,800 --> 00:29:16,200 Imagine a future where we've not only established 988 00:29:16,200 --> 00:29:18,520 a sustainable presence beyond Earth, 989 00:29:18,520 --> 00:29:20,920 but also use that experience to solve 990 00:29:20,920 --> 00:29:23,240 some of our most pressing problems here at home. 991 00:29:23,240 --> 00:29:25,160 It's a vision worth striving for. 992 00:29:25,160 --> 00:29:25,840 Absolutely. 993 00:29:25,840 --> 00:29:26,680 And who knows? 994 00:29:26,680 --> 00:29:27,200 Yeah. 995 00:29:27,200 --> 00:29:30,160 Maybe one day we'll look back at this moment 996 00:29:30,160 --> 00:29:33,280 as the beginning of a new chapter in human history. 997 00:29:33,280 --> 00:29:34,160 It's possible. 998 00:29:34,160 --> 00:29:37,880 A chapter written not just on Earth, but among the stars. 999 00:29:37,880 --> 00:29:40,320 I can't wait to see what that chapter holds. 1000 00:29:40,320 --> 00:29:43,600 And that's a wrap on our deep dive into space colonization. 1001 00:29:43,600 --> 00:29:44,480 It's been a good one. 1002 00:29:44,480 --> 00:29:47,600 A huge thank you to our expert for guiding us 1003 00:29:47,600 --> 00:29:49,720 through this fascinating and complex topic. 1004 00:29:49,720 --> 00:29:50,720 It's been my pleasure. 1005 00:29:50,720 --> 00:29:51,800 And to our listeners. 1006 00:29:51,800 --> 00:29:52,560 Yes. 1007 00:29:52,560 --> 00:29:55,760 If you've enjoyed this exploration of the cosmos, 1008 00:29:55,760 --> 00:29:58,520 be sure to follow Cosmos in a pod. 1009 00:29:58,520 --> 00:29:59,040 Yes. 1010 00:29:59,040 --> 00:30:01,280 And subscribe to our YouTube channel. 1011 00:30:01,280 --> 00:30:01,960 Absolutely. 1012 00:30:01,960 --> 00:30:05,280 For more deep dives into the wonders of the universe. 1013 00:30:05,280 --> 00:30:06,440 We'll see you there. 1014 00:30:06,440 --> 00:30:08,040 Until next time. 1015 00:30:08,040 --> 00:30:09,800 Keep looking up. 1016 00:30:09,800 --> 00:30:22,000 And keep dreaming big.
