1 00:00:08,520 --> 00:00:12,320 Speaker 1: Hey, Daniel, have you been ordering stuff online a lot lately. Yeah, 2 00:00:12,360 --> 00:00:16,080 Speaker 1: you know, like everyone, I've been clicking on websites rather 3 00:00:16,120 --> 00:00:18,239 Speaker 1: than visiting stores. Yeah, you don't need a mass when 4 00:00:18,239 --> 00:00:21,440 Speaker 1: you click. I guess it is pretty amazing how inexpensive 5 00:00:21,480 --> 00:00:23,640 Speaker 1: it is these days to get stuff sent to your 6 00:00:23,720 --> 00:00:25,760 Speaker 1: house from around the world. Even if it comes from 7 00:00:25,840 --> 00:00:28,400 Speaker 1: the other side of the planet. It can just be 8 00:00:28,440 --> 00:00:31,120 Speaker 1: like a few cents per gram to ship it to 9 00:00:31,200 --> 00:00:33,479 Speaker 1: your house. Yeah, you know, I wonder when we can 10 00:00:33,520 --> 00:00:37,160 Speaker 1: start ordering stuff from even further away. I've been trying 11 00:00:37,159 --> 00:00:39,519 Speaker 1: to order some moon rocks. I wonder how much is 12 00:00:39,520 --> 00:00:42,480 Speaker 1: the shipping on those things. Well, I heard NASA spent 13 00:00:42,520 --> 00:00:46,559 Speaker 1: about three hundred thousand dollars per gram to get some 14 00:00:46,640 --> 00:00:48,440 Speaker 1: moon rocks. But you know, I think it's cheaper if 15 00:00:48,479 --> 00:00:51,800 Speaker 1: you have prime. You know, Jeff Bezos is starting his 16 00:00:51,880 --> 00:00:55,120 Speaker 1: own rocket company, so he's probably gonna link that up 17 00:00:55,160 --> 00:00:57,640 Speaker 1: and make it super cheap. Yeah. Why visit other planets 18 00:00:57,640 --> 00:01:15,800 Speaker 1: when you can just order a little bit of him online? Hi, 19 00:01:15,840 --> 00:01:17,840 Speaker 1: am or Hey, I'm a cartoonist and the creator of 20 00:01:17,920 --> 00:01:22,120 Speaker 1: PhD Comics. I'm Daniel. I'm a particle physicist and I 21 00:01:22,120 --> 00:01:24,680 Speaker 1: would love to have a little bit of Jupiter delivered 22 00:01:24,720 --> 00:01:29,319 Speaker 1: to my house. Really, isn't Jupiter mostly gas? So you 23 00:01:29,400 --> 00:01:31,759 Speaker 1: just wanted like a canister or just to like release 24 00:01:31,840 --> 00:01:33,440 Speaker 1: it in your home, to know that you breathe it 25 00:01:33,480 --> 00:01:35,440 Speaker 1: in a little bit of Jupiter. Well, you know, Jupiter 26 00:01:35,560 --> 00:01:37,520 Speaker 1: is mostly gas, but some of that gas is in 27 00:01:37,560 --> 00:01:41,160 Speaker 1: a really weird state, like metallic hydrogen. And that makes 28 00:01:41,200 --> 00:01:43,600 Speaker 1: me really curious. I really want to see what metallic 29 00:01:43,720 --> 00:01:46,639 Speaker 1: hydrogen looks like. It doesn't need to be like super 30 00:01:46,760 --> 00:01:49,560 Speaker 1: under pressure. Hey, these are all engineering details. I just 31 00:01:49,640 --> 00:01:52,200 Speaker 1: want the metallic hydrogen or to my house. I'm just 32 00:01:52,280 --> 00:01:54,600 Speaker 1: clicking and waiting. I want a little bit of that 33 00:01:54,920 --> 00:01:58,080 Speaker 1: gas from the red eye of Jupiter, like it is 34 00:01:58,080 --> 00:02:01,600 Speaker 1: the gas. Also read what's going on there? I think 35 00:02:01,600 --> 00:02:03,440 Speaker 1: we did a whole podcast episode on that one, like 36 00:02:03,480 --> 00:02:06,400 Speaker 1: I should listen to it. But welcome to said podcast. 37 00:02:06,480 --> 00:02:09,200 Speaker 1: Daniel and Jorge Explain the Universe, a production of I 38 00:02:09,360 --> 00:02:11,440 Speaker 1: Heart Radio in which we let you stay at home 39 00:02:11,480 --> 00:02:15,640 Speaker 1: and order in information about the whole universe delivered to 40 00:02:15,800 --> 00:02:18,799 Speaker 1: your ears without any effort on your part. We talk 41 00:02:18,840 --> 00:02:21,680 Speaker 1: about things in the universe that are super far away. 42 00:02:21,960 --> 00:02:25,280 Speaker 1: We talked about the tiny particles that are swimming inside 43 00:02:25,280 --> 00:02:28,040 Speaker 1: your body. We talk about everything and anything, and we 44 00:02:28,120 --> 00:02:30,120 Speaker 1: try to explain all of it to you. That's right. 45 00:02:30,160 --> 00:02:33,440 Speaker 1: We try to bring the universe and the cosmos and 46 00:02:33,480 --> 00:02:38,240 Speaker 1: everything in between to your brain free of charge, because 47 00:02:38,320 --> 00:02:41,160 Speaker 1: wondering belongs to everybody, and the questions that you have 48 00:02:41,400 --> 00:02:44,680 Speaker 1: about space and physics and the universe are the questions 49 00:02:44,720 --> 00:02:48,720 Speaker 1: that everybody has, and the same questions that scientists want 50 00:02:48,760 --> 00:02:51,720 Speaker 1: answers to, because we're all still learning about the universe, 51 00:02:51,760 --> 00:02:54,520 Speaker 1: and part of that learning is exploring, is going out 52 00:02:54,560 --> 00:02:58,280 Speaker 1: into the cosmos, into other planets, into the stars, and 53 00:02:58,400 --> 00:03:01,720 Speaker 1: figuring out what's going on and what is there for 54 00:03:01,840 --> 00:03:04,880 Speaker 1: us to discover. And sometimes it's so depressing to think 55 00:03:04,919 --> 00:03:08,799 Speaker 1: that we've explored such a tiny little fraction of our universe. 56 00:03:09,160 --> 00:03:12,359 Speaker 1: You know, we've barely gotten off this planet to explore 57 00:03:12,400 --> 00:03:16,120 Speaker 1: the Moon, to land a few rovers on Mars. It's incredible, 58 00:03:16,240 --> 00:03:18,760 Speaker 1: what a tiny little dot of the universe we have 59 00:03:18,840 --> 00:03:20,880 Speaker 1: been able to explore so far. But what a dot 60 00:03:20,960 --> 00:03:24,520 Speaker 1: it is. It's a pretty cool dot, and we're lucky 61 00:03:24,600 --> 00:03:26,920 Speaker 1: that there is something to explore. I mean, right in 62 00:03:26,919 --> 00:03:31,320 Speaker 1: our neighborhood, right next door, there's an amazing planet, Mars, 63 00:03:31,360 --> 00:03:35,240 Speaker 1: that really has a lot of tantalizing and fascinating scientific question. Yeah, 64 00:03:35,280 --> 00:03:38,000 Speaker 1: Mars is awesome, and so we'd like to know a 65 00:03:38,040 --> 00:03:41,000 Speaker 1: little bit more about what is there on Mars. I 66 00:03:41,000 --> 00:03:43,440 Speaker 1: mean we can see it, but so far we haven't 67 00:03:43,480 --> 00:03:45,920 Speaker 1: been able to really, I don't know, study it up close. 68 00:03:46,120 --> 00:03:48,880 Speaker 1: It's pretty hard because it's so far away. And all 69 00:03:48,920 --> 00:03:51,200 Speaker 1: we've been able to do so far is send our 70 00:03:51,520 --> 00:03:54,400 Speaker 1: robots there and have them do science. But that's sort 71 00:03:54,440 --> 00:03:56,440 Speaker 1: of like trying to do science with a ten foot 72 00:03:56,440 --> 00:03:59,960 Speaker 1: poll or a ten million mile long pole, and that's 73 00:04:00,120 --> 00:04:03,120 Speaker 1: not easy to do. That's kind of a philosophical question, 74 00:04:03,160 --> 00:04:05,920 Speaker 1: isn't it, Daniel, Like if you send a robot out 75 00:04:06,040 --> 00:04:09,840 Speaker 1: to explore something, have you explored it technically? Like if 76 00:04:09,840 --> 00:04:12,960 Speaker 1: the robot touches Mars, did you touch Mars? That humans 77 00:04:13,000 --> 00:04:15,520 Speaker 1: touch Mars? Yeah, I mean if you have a robotic hand, 78 00:04:15,920 --> 00:04:18,520 Speaker 1: you consider it part of yourself. If you touch something 79 00:04:18,560 --> 00:04:20,560 Speaker 1: with that hand, then it's part of you. And so 80 00:04:20,839 --> 00:04:25,160 Speaker 1: this is just like a spatially disconnected prosthetic, right, think 81 00:04:25,160 --> 00:04:28,560 Speaker 1: about the rovers as part of your body. Then. Yeah, philosophically, 82 00:04:28,839 --> 00:04:30,800 Speaker 1: I've been on Mars. I wonder if the Mars were 83 00:04:30,839 --> 00:04:34,000 Speaker 1: over would disagree. When he gets to the point that 84 00:04:34,040 --> 00:04:36,239 Speaker 1: it can disagree, it's no longer part of your body. 85 00:04:37,600 --> 00:04:39,400 Speaker 1: It has its own Twitter account. Do you know that 86 00:04:39,480 --> 00:04:41,760 Speaker 1: the Mars rover has its own Twitter account? It has 87 00:04:41,800 --> 00:04:44,920 Speaker 1: more followers than I do. Yeah, but did get off 88 00:04:44,920 --> 00:04:47,960 Speaker 1: its couch, Daniel, And actually, you know went somewhere. It 89 00:04:48,000 --> 00:04:50,200 Speaker 1: has accomplished more in its life than I ever will. 90 00:04:50,320 --> 00:04:52,640 Speaker 1: That's true. But yeah, we'd love to know more about 91 00:04:52,720 --> 00:04:55,200 Speaker 1: Mars and whether or not it had life on it, 92 00:04:55,480 --> 00:04:58,880 Speaker 1: like bacteria or who knows what else we could discover 93 00:04:58,920 --> 00:05:00,800 Speaker 1: that Mars had, but it's really hard to do it 94 00:05:00,880 --> 00:05:03,640 Speaker 1: from here, and even to do it through robots. It 95 00:05:03,720 --> 00:05:06,480 Speaker 1: is challenging, and it's amazing to me how open this 96 00:05:06,600 --> 00:05:09,640 Speaker 1: question remains. You know, through history we thought, oh, maybe 97 00:05:09,680 --> 00:05:11,880 Speaker 1: Mars has life on it. Then we took a closer look, 98 00:05:11,880 --> 00:05:14,600 Speaker 1: where like, actually it looks pretty dry. They're like, wait, no, 99 00:05:14,760 --> 00:05:17,640 Speaker 1: there is water on there. Maybe there are microbes, and 100 00:05:17,680 --> 00:05:19,960 Speaker 1: so keep going up and down, and it's fascinating to 101 00:05:19,960 --> 00:05:22,480 Speaker 1: me that this planet, this one that the closest to us. 102 00:05:22,920 --> 00:05:25,960 Speaker 1: We still don't know the answer. If there is life 103 00:05:25,960 --> 00:05:27,880 Speaker 1: on Mars, is it's similar to Earth? Did it come 104 00:05:27,920 --> 00:05:30,600 Speaker 1: to Earth from Mars, or to Mars from Earth, or 105 00:05:30,839 --> 00:05:34,560 Speaker 1: to both planets from somewhere else. It's an incredibly important question, 106 00:05:34,640 --> 00:05:38,000 Speaker 1: and it's right there, it's so accessible. Yeah, that's a 107 00:05:38,080 --> 00:05:41,200 Speaker 1: huge question, right, But they're not Life on Earth actually 108 00:05:41,240 --> 00:05:44,240 Speaker 1: started on Mars. Because it's possible that there was life 109 00:05:44,279 --> 00:05:47,640 Speaker 1: on Mars and then got knocked off on an asteroid 110 00:05:47,760 --> 00:05:50,520 Speaker 1: and then flew here and landed on Earth, and that's 111 00:05:50,520 --> 00:05:53,680 Speaker 1: how life started Earth. That's a theory, right, That is 112 00:05:53,720 --> 00:05:55,560 Speaker 1: a theory, and it's not just the plot of a 113 00:05:55,600 --> 00:05:59,240 Speaker 1: science fiction novel. It's potentially actually plausible, and it's a 114 00:05:59,320 --> 00:06:01,960 Speaker 1: kind of question that we could answer if we had 115 00:06:02,000 --> 00:06:05,360 Speaker 1: deeper access to rocks on Mars. Right, we could all 116 00:06:05,360 --> 00:06:09,760 Speaker 1: be Martians. Martians could all be Earthlings. Who knows, we 117 00:06:09,800 --> 00:06:12,080 Speaker 1: could all be Jovians. Yeah, but it'd be great to 118 00:06:12,160 --> 00:06:13,960 Speaker 1: answer that question. And I think the only way we're 119 00:06:13,960 --> 00:06:16,200 Speaker 1: going to answer that question is to actually go there 120 00:06:16,320 --> 00:06:19,359 Speaker 1: and take a close look at the rocks and the 121 00:06:19,520 --> 00:06:22,520 Speaker 1: soil and to like actually like take a super microscope 122 00:06:22,520 --> 00:06:24,920 Speaker 1: to it and see if we see any little critters 123 00:06:24,920 --> 00:06:27,560 Speaker 1: in there. That's right, But sending scientists to Mars is 124 00:06:27,640 --> 00:06:32,200 Speaker 1: unfortunately still many many years away, decades probably if ever. 125 00:06:32,320 --> 00:06:35,080 Speaker 1: It's really hard, but we've done it with some things 126 00:06:35,080 --> 00:06:37,680 Speaker 1: in space, like for example, we've gone to the Moon 127 00:06:37,920 --> 00:06:40,000 Speaker 1: and gone and rock from the Moon and brought them 128 00:06:40,040 --> 00:06:42,200 Speaker 1: back to Earth. I think you can order them online, right, 129 00:06:42,800 --> 00:06:46,080 Speaker 1: I don't think you can order them online. No, you can. Can. 130 00:06:46,200 --> 00:06:48,160 Speaker 1: You get on eBay and like a bid on a 131 00:06:48,520 --> 00:06:50,600 Speaker 1: piece of moon rock. I think anything you buy on 132 00:06:50,720 --> 00:06:53,359 Speaker 1: eBay is not going to be actually moon rocks, so 133 00:06:53,720 --> 00:06:57,440 Speaker 1: please don't waste your money. But we did actually bring 134 00:06:57,600 --> 00:06:59,960 Speaker 1: rocks back from the Moon, and those rocks have been 135 00:07:00,040 --> 00:07:03,800 Speaker 1: an incredible treasure trove of science. Were like still thinking 136 00:07:03,800 --> 00:07:06,760 Speaker 1: of new things to do to those rocks, to learn things, 137 00:07:07,040 --> 00:07:10,240 Speaker 1: to figure out answers to new questions about the science 138 00:07:10,400 --> 00:07:13,800 Speaker 1: of the Moon. So it's incredibly valuable to have here 139 00:07:13,840 --> 00:07:17,280 Speaker 1: in our Earth laboratories a sample from the Moon or 140 00:07:17,360 --> 00:07:20,560 Speaker 1: from somewhere else. Yeah. I have actually held in moon rock. 141 00:07:21,000 --> 00:07:22,960 Speaker 1: I was at JPO of visiting ones and they let 142 00:07:23,000 --> 00:07:25,000 Speaker 1: me hold a little bit of moon dust, And did 143 00:07:25,000 --> 00:07:29,280 Speaker 1: you feel transported? I accidentally breedd them in and sneeze 144 00:07:30,760 --> 00:07:34,400 Speaker 1: had to go in there for a second. That sounds 145 00:07:34,440 --> 00:07:37,000 Speaker 1: like the opening scene of a terrible science fiction novel. 146 00:07:38,040 --> 00:07:40,880 Speaker 1: Or he gets infected by a Moon based pathoge and 147 00:07:40,920 --> 00:07:44,960 Speaker 1: that's why I have superpowers. You gained the Moon's proportional 148 00:07:45,000 --> 00:07:49,120 Speaker 1: strength again, the ambility to moon people. You cause tides. Right, 149 00:07:49,160 --> 00:07:51,760 Speaker 1: you'd be a some sort of lunar superhuman. That's right. 150 00:07:51,800 --> 00:07:55,120 Speaker 1: I'm like the villain in the next Appman movie. That's right, 151 00:07:55,160 --> 00:07:59,800 Speaker 1: You're like the DC version of Magneto. Right, you insulted 152 00:07:59,800 --> 00:08:02,720 Speaker 1: me twice over there. You just confuse the DC character 153 00:08:02,920 --> 00:08:05,600 Speaker 1: with the Marvel character. No, I'm trying to bring one 154 00:08:05,640 --> 00:08:08,200 Speaker 1: from the other, right, Like Magneto controls medals, and so 155 00:08:08,480 --> 00:08:13,400 Speaker 1: lunar Jorge controls tides right in the DC universe. But anyways, 156 00:08:13,600 --> 00:08:15,320 Speaker 1: so the question is, can we just go to Mars, 157 00:08:15,360 --> 00:08:16,960 Speaker 1: pick up some rocks and bring them back and then 158 00:08:17,000 --> 00:08:20,120 Speaker 1: study them, and then we would know if life potentially 159 00:08:20,240 --> 00:08:22,760 Speaker 1: came from another planet. That would be incredible. And so 160 00:08:22,800 --> 00:08:24,600 Speaker 1: to be on the program, we'll be asking the question, 161 00:08:29,480 --> 00:08:34,040 Speaker 1: can we bring rocks back from Mars? Or more optimistically, 162 00:08:34,320 --> 00:08:38,200 Speaker 1: how can we bring rocks back from Mars? Oh, so 163 00:08:38,240 --> 00:08:40,280 Speaker 1: you're feeling good. You feel like it's not an if question, 164 00:08:40,480 --> 00:08:43,080 Speaker 1: it's not a physics question, right, there's nothing in physics 165 00:08:43,080 --> 00:08:46,320 Speaker 1: that prevents us from moving rocks from Mars to Earth. 166 00:08:46,360 --> 00:08:49,640 Speaker 1: It's definitely an engineering question, and as you'll hear, it's 167 00:08:49,679 --> 00:08:52,440 Speaker 1: a tricky one. So, as usually, we were wondering how 168 00:08:52,440 --> 00:08:55,120 Speaker 1: many people out there had thought about this question or 169 00:08:55,160 --> 00:08:58,120 Speaker 1: wonder whether or not it's possible to bring something back 170 00:08:58,160 --> 00:09:01,240 Speaker 1: from Mars. So Daniel and out there into the wilds 171 00:09:01,240 --> 00:09:04,360 Speaker 1: of the Internet to ask people how can we retrieve 172 00:09:04,480 --> 00:09:07,920 Speaker 1: rocks from Mars to study them on Earth. So these 173 00:09:07,920 --> 00:09:10,000 Speaker 1: are the answers I got from random folks on the 174 00:09:10,040 --> 00:09:14,440 Speaker 1: Internet who were willing to speculate baselessly without any googling 175 00:09:14,679 --> 00:09:17,320 Speaker 1: about the questions. I asked them, if you'd like to 176 00:09:17,360 --> 00:09:19,920 Speaker 1: participate and hear your voice on the podcast at some 177 00:09:19,960 --> 00:09:22,800 Speaker 1: point in the future, please write to us two questions 178 00:09:22,840 --> 00:09:25,440 Speaker 1: at Daniel and Jorge dot com. Here's what people had 179 00:09:25,440 --> 00:09:27,640 Speaker 1: to say. I think that we should send a rocket 180 00:09:27,679 --> 00:09:30,840 Speaker 1: to Mars, and then maybe the Mars wherever the acrono 181 00:09:30,920 --> 00:09:34,679 Speaker 1: Mars should take the rock samples and put them inside 182 00:09:34,679 --> 00:09:37,760 Speaker 1: the rocket, and then we could somehow program the rocket 183 00:09:37,920 --> 00:09:40,480 Speaker 1: to fly back on its own. Perseverance is on his 184 00:09:40,559 --> 00:09:42,760 Speaker 1: way there right now, and hopefully the next generation of 185 00:09:42,800 --> 00:09:45,520 Speaker 1: Perseverances will be able to bring them back to study. 186 00:09:45,880 --> 00:09:50,440 Speaker 1: I thought that that was part of the upcoming Mars mission, 187 00:09:50,679 --> 00:09:53,680 Speaker 1: or maybe for the next mission to have some sort 188 00:09:53,920 --> 00:09:57,280 Speaker 1: of return capsule. It's really difficult to get things back 189 00:09:57,320 --> 00:10:00,960 Speaker 1: from Mars, so I imagine that probably have to send 190 00:10:01,520 --> 00:10:03,880 Speaker 1: some sort of probe there that would then have to 191 00:10:03,920 --> 00:10:07,480 Speaker 1: do a lot of the analysis they're on Mars. I 192 00:10:07,520 --> 00:10:10,840 Speaker 1: think the new Perseverance wherever you can actually collect unstored 193 00:10:10,840 --> 00:10:13,280 Speaker 1: Mars rocks for a future mission to achieve and bring 194 00:10:13,320 --> 00:10:16,280 Speaker 1: back to Earth. I'm envisioning maybe we send something to 195 00:10:16,360 --> 00:10:19,760 Speaker 1: like enter into Mars's orbit that can maybe send down 196 00:10:19,800 --> 00:10:23,719 Speaker 1: an explosive heads the surface, sends out a bunch of particulates. 197 00:10:24,200 --> 00:10:28,000 Speaker 1: The probe gathers these particulates and then breaks out of 198 00:10:28,000 --> 00:10:31,400 Speaker 1: the orbit goes back to Earth. We can gather samples 199 00:10:31,440 --> 00:10:34,040 Speaker 1: from Mars for study on Earth, kind of how we 200 00:10:34,080 --> 00:10:38,600 Speaker 1: went to the Moon, except all robotically right, and instead 201 00:10:38,600 --> 00:10:40,840 Speaker 1: of a lamb, we have a mam. Well, I know 202 00:10:40,880 --> 00:10:43,000 Speaker 1: we already have a mission going there, and I believe 203 00:10:43,040 --> 00:10:45,360 Speaker 1: what they're going to do is h do little core 204 00:10:45,480 --> 00:10:49,680 Speaker 1: samples and then somehow package them and leave them for 205 00:10:49,720 --> 00:10:52,880 Speaker 1: a recovery mission. Al Right, a lot of excitement about 206 00:10:52,880 --> 00:10:55,199 Speaker 1: this idea. I feel, yeah, a lot of excitement. People 207 00:10:55,200 --> 00:10:58,000 Speaker 1: are like, I don't know, but it sounds cool. Somebody 208 00:10:58,000 --> 00:11:00,439 Speaker 1: out there is like, let's just nuke Mars, and I 209 00:11:00,480 --> 00:11:04,559 Speaker 1: have the feeling they were just waiting for the opportunity. 210 00:11:04,640 --> 00:11:08,200 Speaker 1: Is that a fellow physicist? I feel like that sounds 211 00:11:08,200 --> 00:11:11,079 Speaker 1: like an efficient solution to a physicist. You don't think 212 00:11:11,080 --> 00:11:13,560 Speaker 1: an engineer would be like, let's just shoot a string 213 00:11:13,640 --> 00:11:15,960 Speaker 1: of nuclear weapons at this thing to guide it back 214 00:11:15,960 --> 00:11:20,240 Speaker 1: to Earth. I think you mean a freshman engineer would 215 00:11:20,240 --> 00:11:22,360 Speaker 1: be like, maybe there's a better way, that's right, and 216 00:11:22,400 --> 00:11:25,920 Speaker 1: also would probably destroy the samples and pollute them with radiation, 217 00:11:26,200 --> 00:11:29,199 Speaker 1: so it might undermine the very science that we're trying 218 00:11:29,240 --> 00:11:31,719 Speaker 1: to do. Right, that's probably a huge part of it, right, 219 00:11:31,800 --> 00:11:35,640 Speaker 1: like not contaminating. Oh yeah, that's a big deal. All right, Well, 220 00:11:35,720 --> 00:11:39,040 Speaker 1: let's dig into this topic. Let's get some samples of 221 00:11:39,120 --> 00:11:41,880 Speaker 1: it and retreat it and bring it to Earth. So Daniel, 222 00:11:41,920 --> 00:11:44,360 Speaker 1: first of all, I guess talk about why we would 223 00:11:45,000 --> 00:11:47,040 Speaker 1: want to get rocks from Mars. I mean, I know 224 00:11:47,080 --> 00:11:49,959 Speaker 1: that it would be great to study them, but you know, 225 00:11:50,000 --> 00:11:51,960 Speaker 1: why can't we just study them there. Well, we can 226 00:11:52,040 --> 00:11:54,400 Speaker 1: do a lot of studying on the surface of Mars, 227 00:11:54,440 --> 00:11:57,560 Speaker 1: and we have rovers that do that, but it's tricky. 228 00:11:57,920 --> 00:11:59,840 Speaker 1: You want to do some science on a rover, you 229 00:12:00,080 --> 00:12:03,560 Speaker 1: have to pick an instrument which can survive like launch 230 00:12:03,960 --> 00:12:08,040 Speaker 1: and transit and landing on Mars, and then can get 231 00:12:08,080 --> 00:12:11,280 Speaker 1: set up automatically without any like a grad students tinkering 232 00:12:11,320 --> 00:12:14,040 Speaker 1: with it. You know, every cutting edge lab that I'm 233 00:12:14,080 --> 00:12:16,959 Speaker 1: aware of here on Earth, the most powerful instruments are 234 00:12:17,080 --> 00:12:20,360 Speaker 1: delicate instruments, and they require like experts tweaking them and 235 00:12:20,400 --> 00:12:23,439 Speaker 1: massaging them to make them work and to calibrate them. 236 00:12:23,720 --> 00:12:25,760 Speaker 1: So for something to work on a rover has to 237 00:12:25,760 --> 00:12:29,120 Speaker 1: be really robust, and that really limits the kinds of 238 00:12:29,160 --> 00:12:30,760 Speaker 1: signs that you can do. Yeah, I guess you need 239 00:12:30,800 --> 00:12:33,800 Speaker 1: a lab. And it's tricky to handle these samples and 240 00:12:33,840 --> 00:12:36,079 Speaker 1: to do the the signs, right, that's right. If you 241 00:12:36,120 --> 00:12:39,280 Speaker 1: had your hands on Martian samples like right now, there's 242 00:12:39,320 --> 00:12:41,280 Speaker 1: like a hundred things you would want to do to 243 00:12:41,320 --> 00:12:43,920 Speaker 1: it right away, but only a few of those ever 244 00:12:44,000 --> 00:12:47,120 Speaker 1: make it onto a rover, so you're really limited. And 245 00:12:47,120 --> 00:12:49,160 Speaker 1: then you get the answers back, you're like, oh, look 246 00:12:49,160 --> 00:12:50,959 Speaker 1: it has this weird thing in it. Now I want 247 00:12:50,960 --> 00:12:53,680 Speaker 1: to check with my other funky instrument. But you can't 248 00:12:53,679 --> 00:12:55,840 Speaker 1: do that kind of thing all in advance. When you 249 00:12:55,880 --> 00:12:58,199 Speaker 1: send your rover over, you have to plan very far 250 00:12:58,240 --> 00:13:00,720 Speaker 1: in advance exactly what you're gonna do to every sample. 251 00:13:00,960 --> 00:13:04,000 Speaker 1: You can't respond to what you've learned with new ideas, 252 00:13:04,240 --> 00:13:06,839 Speaker 1: whereas if you bring the rocks back, then you can 253 00:13:06,920 --> 00:13:09,000 Speaker 1: keep coming up with new ideas. And also you have 254 00:13:09,040 --> 00:13:12,439 Speaker 1: access to future instruments. Right, cool techniques we're going to 255 00:13:12,520 --> 00:13:14,680 Speaker 1: develop in ten years or in twenty years that we 256 00:13:14,720 --> 00:13:17,559 Speaker 1: haven't even thought of. Now we have the rocks here, 257 00:13:18,080 --> 00:13:21,040 Speaker 1: rather than sending the machines there, then we can use 258 00:13:21,120 --> 00:13:24,360 Speaker 1: new machines on old rocks, right, Because I guess it's 259 00:13:24,880 --> 00:13:28,080 Speaker 1: you know, it's really hard to take stuff to Mars, right, 260 00:13:28,120 --> 00:13:30,720 Speaker 1: I mean, like every gram cost like a million dollars 261 00:13:30,800 --> 00:13:34,720 Speaker 1: or something, and these lab equipment machines are really big. 262 00:13:34,920 --> 00:13:36,920 Speaker 1: Sometimes they are really big, and a lot of the 263 00:13:37,000 --> 00:13:41,080 Speaker 1: engineering challenges of building a rover or how to miniaturize, right, 264 00:13:41,080 --> 00:13:43,640 Speaker 1: how to make these things really small. It's got to 265 00:13:43,720 --> 00:13:45,760 Speaker 1: be like the size of a shoe box and fit 266 00:13:45,800 --> 00:13:48,680 Speaker 1: on the edge of a stick and be totally robust, 267 00:13:48,760 --> 00:13:50,280 Speaker 1: Like you have to just be able to send it 268 00:13:50,320 --> 00:13:52,640 Speaker 1: one command and it boots up and starts up. It's 269 00:13:52,640 --> 00:13:54,560 Speaker 1: gonna have a little bit of AI in there to 270 00:13:54,600 --> 00:13:57,520 Speaker 1: get itself going. Right. You can't just like crawl out 271 00:13:57,520 --> 00:13:59,800 Speaker 1: there with your screw driver and fix it right once 272 00:13:59,840 --> 00:14:02,120 Speaker 1: you send it, it's gone. You can't just call I 273 00:14:02,200 --> 00:14:04,920 Speaker 1: T to fix it, and they'll say, have you tried 274 00:14:04,960 --> 00:14:08,120 Speaker 1: turning it off and turning it on again? Did you 275 00:14:08,200 --> 00:14:11,160 Speaker 1: update your Windows installation like I can. It's on Mars. 276 00:14:11,240 --> 00:14:14,400 Speaker 1: I can't even turn it on enough. No, And you 277 00:14:14,440 --> 00:14:18,160 Speaker 1: can't even like drive something on Mars. Remember these rovers 278 00:14:18,200 --> 00:14:22,960 Speaker 1: operate semi autonomously because Mars is so far away that 279 00:14:23,080 --> 00:14:25,760 Speaker 1: it takes light minutes to get there. So you can't 280 00:14:25,800 --> 00:14:28,720 Speaker 1: have the kind of feedback loop you need to real 281 00:14:28,880 --> 00:14:31,880 Speaker 1: time drive something on Mars. It's like you drive forward, 282 00:14:31,960 --> 00:14:34,080 Speaker 1: you stop, you take a picture, you send it back 283 00:14:34,120 --> 00:14:36,720 Speaker 1: to the folks in NASA. They figure out what to 284 00:14:36,760 --> 00:14:39,560 Speaker 1: do next. And so having it be so far away 285 00:14:39,640 --> 00:14:41,880 Speaker 1: makes it really limited. It has to survive a trip 286 00:14:41,920 --> 00:14:46,080 Speaker 1: to Like launching from the Earth into space is not easy, right, 287 00:14:46,120 --> 00:14:49,000 Speaker 1: Like there's huge forces and you know you're basically strapped 288 00:14:49,040 --> 00:14:52,000 Speaker 1: onto a giant explosion. It has to survive that. And 289 00:14:52,040 --> 00:14:54,480 Speaker 1: also the landing on Mars, which can be pretty tough, 290 00:14:54,720 --> 00:14:58,440 Speaker 1: like sometimes they just fall into the ground and bounce around, 291 00:14:58,720 --> 00:15:01,480 Speaker 1: and it has to survive that. That's the landing strategy. 292 00:15:01,840 --> 00:15:04,760 Speaker 1: That's the design strategy, right. I mean, remember all those 293 00:15:04,760 --> 00:15:07,480 Speaker 1: movies about astronaut training, Like they put those folks through 294 00:15:07,520 --> 00:15:11,280 Speaker 1: some tough stuff. They spin around, they shake them a lot. Basically, 295 00:15:11,320 --> 00:15:14,520 Speaker 1: take your most sensitive science instruments and put them through 296 00:15:14,600 --> 00:15:17,040 Speaker 1: astronaut training to see if they have the right stuff. 297 00:15:17,440 --> 00:15:19,920 Speaker 1: Most of the time, it's just gonna fall apart. Like 298 00:15:20,000 --> 00:15:23,440 Speaker 1: you go into a random geology or microbiology lab here 299 00:15:23,480 --> 00:15:26,320 Speaker 1: on Earth. Most of those instruments are very delicate. They 300 00:15:26,320 --> 00:15:29,240 Speaker 1: don't let people in there poking and products. So you're right, 301 00:15:29,480 --> 00:15:32,200 Speaker 1: surviving all the shaking and the landing and all that stuff. 302 00:15:32,360 --> 00:15:35,520 Speaker 1: It's not easy. So this whole categories of instruments, nobody 303 00:15:35,560 --> 00:15:38,400 Speaker 1: has figured out how to miniaturize and make robust enough 304 00:15:38,480 --> 00:15:40,400 Speaker 1: to send to Mars. Okay, so it would be a 305 00:15:40,400 --> 00:15:43,520 Speaker 1: lot better for science if we could bring some Mars 306 00:15:43,680 --> 00:15:46,440 Speaker 1: rocks back so we can study them, and you know, 307 00:15:46,480 --> 00:15:49,160 Speaker 1: you can do a whole bunch more tescent. You could 308 00:15:49,160 --> 00:15:52,239 Speaker 1: on a robot in Mars, but it's really hard and 309 00:15:52,480 --> 00:15:55,560 Speaker 1: apparently it can't just study meteors from Mars. Like that's 310 00:15:55,560 --> 00:15:58,880 Speaker 1: another possibility, but it's not, as I guess. Fresh. Yeah, 311 00:15:58,920 --> 00:16:02,680 Speaker 1: the amazing thing is that we actually already have Mars rocks, right, 312 00:16:02,760 --> 00:16:04,760 Speaker 1: like what yeah, what you were talking about sort of 313 00:16:04,800 --> 00:16:08,840 Speaker 1: as a joke, actually happens. Sometimes big rocks hit the 314 00:16:08,880 --> 00:16:12,560 Speaker 1: surface of Mars right impact creators and stuff gets thrown 315 00:16:12,600 --> 00:16:15,280 Speaker 1: out into space. You know, this can be really big 316 00:16:15,320 --> 00:16:18,280 Speaker 1: impacts and some of those rocks get tossed out into 317 00:16:18,280 --> 00:16:21,240 Speaker 1: space and eventually a small fraction of them hit the 318 00:16:21,280 --> 00:16:23,800 Speaker 1: surface of the Earth and then are recovered. And how 319 00:16:23,800 --> 00:16:25,840 Speaker 1: do we know they're from Mars? So they had like 320 00:16:25,840 --> 00:16:29,280 Speaker 1: a maide in Mars tag or well they went through customs, right, 321 00:16:29,520 --> 00:16:31,240 Speaker 1: and so we can tell they just look at the 322 00:16:31,240 --> 00:16:34,720 Speaker 1: forms they I mean, can you tell, like does it 323 00:16:34,840 --> 00:16:37,640 Speaker 1: have a special like queue of red or something? You 324 00:16:37,680 --> 00:16:40,040 Speaker 1: can tell because of the geology, every object in the 325 00:16:40,080 --> 00:16:43,240 Speaker 1: Solar System has a different history and a different composition 326 00:16:43,640 --> 00:16:45,640 Speaker 1: and that tells you where it comes from. And so 327 00:16:45,680 --> 00:16:47,840 Speaker 1: when you get a meteor from outer space, when you've 328 00:16:47,840 --> 00:16:50,120 Speaker 1: got a chunk of space rock. First of all, you 329 00:16:50,120 --> 00:16:51,880 Speaker 1: can tell it the space rock because of what it's 330 00:16:51,920 --> 00:16:54,040 Speaker 1: made out of. It's made of stuff you don't find 331 00:16:54,160 --> 00:16:56,440 Speaker 1: on Earth. And then you can tell roughly where it 332 00:16:56,480 --> 00:16:58,840 Speaker 1: came from based on the details of what's in it. 333 00:16:59,120 --> 00:17:01,320 Speaker 1: And so most of the rocks that land on Earth come, 334 00:17:01,400 --> 00:17:03,400 Speaker 1: for example, from the asteroid Belt, and we can tell 335 00:17:03,440 --> 00:17:06,760 Speaker 1: based on the blend of metals and also the organization 336 00:17:06,800 --> 00:17:08,640 Speaker 1: of the metals in them that tells you something about 337 00:17:08,680 --> 00:17:11,240 Speaker 1: its history, like when it was last melted and how 338 00:17:11,280 --> 00:17:13,720 Speaker 1: long it's been frozen for. And some of these things 339 00:17:13,720 --> 00:17:17,440 Speaker 1: have composition and geology that's only consistent with the surface 340 00:17:17,480 --> 00:17:20,320 Speaker 1: of Mars. Interesting. So, yeah, we have like dozens of 341 00:17:20,320 --> 00:17:23,320 Speaker 1: these objects that have landed on the Earth from Mars, 342 00:17:23,600 --> 00:17:27,640 Speaker 1: which is fascinating and incredible and wonderful opportunities to do science. 343 00:17:27,840 --> 00:17:30,280 Speaker 1: But it's not good enough, right, Yeah, you need like 344 00:17:30,400 --> 00:17:33,200 Speaker 1: fresh rocks, Like those asteroids are kind of stale. They've 345 00:17:33,200 --> 00:17:36,760 Speaker 1: been floating around face and who knows where they came from. 346 00:17:36,800 --> 00:17:39,119 Speaker 1: It's not just that you need fresh rocks, it's that 347 00:17:39,160 --> 00:17:41,320 Speaker 1: you need to know where they came from, Like it's 348 00:17:41,359 --> 00:17:43,399 Speaker 1: just a random sample. You don't know where on Mars 349 00:17:43,440 --> 00:17:45,199 Speaker 1: it came from, so you can't really like fit it 350 00:17:45,240 --> 00:17:47,959 Speaker 1: into your science picture of what's going on on Mars. 351 00:17:48,280 --> 00:17:50,399 Speaker 1: Which you'd like is to have a rover travel around 352 00:17:50,400 --> 00:17:52,639 Speaker 1: and make judicious decisions and say, I'm gonna get a 353 00:17:52,640 --> 00:17:54,680 Speaker 1: little bit of this kind of rock, and I see 354 00:17:54,720 --> 00:17:57,320 Speaker 1: where it is. It's on the downflow of a slope. 355 00:17:57,440 --> 00:17:59,560 Speaker 1: I'm gonna get that piece of rock over there, and 356 00:17:59,600 --> 00:18:02,560 Speaker 1: I know the scientific context. It's sort of just like 357 00:18:02,920 --> 00:18:05,840 Speaker 1: getting a piece of pottery and having no idea where 358 00:18:05,840 --> 00:18:09,080 Speaker 1: it was dug up from. It's much less valuable scientifically. 359 00:18:09,080 --> 00:18:10,320 Speaker 1: It's also kind of like when you go to a 360 00:18:10,359 --> 00:18:12,879 Speaker 1: Las Vegas bouffet. You know you want judiciously pick a 361 00:18:12,880 --> 00:18:14,920 Speaker 1: little bit from everything and know where you got it from, 362 00:18:14,960 --> 00:18:18,359 Speaker 1: so you can go back and get the stuff you liked. 363 00:18:18,960 --> 00:18:20,560 Speaker 1: That's right, and so you know what made you throw 364 00:18:20,680 --> 00:18:26,159 Speaker 1: up and what you yeah, yeah, alright. So it sounds 365 00:18:26,200 --> 00:18:28,520 Speaker 1: like it would be a lot better if we can 366 00:18:28,560 --> 00:18:31,000 Speaker 1: get go to Mars, get some rocks, bring them back, 367 00:18:31,040 --> 00:18:32,800 Speaker 1: and then study the heck out of him to answer 368 00:18:32,880 --> 00:18:35,679 Speaker 1: these big questions about life in the Solar System and 369 00:18:35,720 --> 00:18:38,199 Speaker 1: about Mars and the history of Mars. But it's a 370 00:18:38,240 --> 00:18:40,440 Speaker 1: tough problem, and so let's talk about how we would 371 00:18:40,480 --> 00:18:43,120 Speaker 1: actually do that and what has been and is being 372 00:18:43,160 --> 00:18:45,840 Speaker 1: done to do it. But first let's take a quick break, 373 00:18:58,520 --> 00:19:02,119 Speaker 1: all right, Daniel, we are souvenir shopping in the Solar System. 374 00:19:02,640 --> 00:19:08,000 Speaker 1: We're trying to get some original, authentic rocks from Mars. 375 00:19:08,040 --> 00:19:10,960 Speaker 1: But it's a tough problem because Mars is really far away, 376 00:19:11,240 --> 00:19:12,840 Speaker 1: and you don't just have to get the rocks. You 377 00:19:12,840 --> 00:19:14,400 Speaker 1: have to come back with them. You've got to come 378 00:19:14,400 --> 00:19:16,320 Speaker 1: back with the rocks. Right, Like we've done the one 379 00:19:16,359 --> 00:19:19,600 Speaker 1: way thing. We've sent something to Mars and it's dug 380 00:19:19,680 --> 00:19:22,800 Speaker 1: up rocks and studied them, but they're still on the 381 00:19:22,800 --> 00:19:25,399 Speaker 1: surface of Mars, and so now we need to do 382 00:19:25,480 --> 00:19:28,080 Speaker 1: the second bit, the round trip, to come home and 383 00:19:28,119 --> 00:19:31,800 Speaker 1: deliver them to scientists in a pristine condition, so that 384 00:19:31,840 --> 00:19:35,920 Speaker 1: we can finally answer some of these incredible, longstanding science questions. Right, 385 00:19:35,960 --> 00:19:38,760 Speaker 1: And I feel like the problem is it's not just double, 386 00:19:38,920 --> 00:19:41,560 Speaker 1: it's like squared, because you know, it's hard enough to 387 00:19:41,640 --> 00:19:44,240 Speaker 1: take off from a planet and land on another planet, 388 00:19:44,520 --> 00:19:46,520 Speaker 1: but now you're gonna do it again, take off from 389 00:19:46,560 --> 00:19:49,040 Speaker 1: there and land here. But it still has to be 390 00:19:49,119 --> 00:19:51,680 Speaker 1: the same machine that you send out, like the same 391 00:19:51,680 --> 00:19:53,960 Speaker 1: machine you send out has to do both of those things. Yeah, 392 00:19:54,080 --> 00:19:57,040 Speaker 1: it's complicated, and it's not just squared as you're gonna hear. 393 00:19:57,040 --> 00:19:59,240 Speaker 1: There's a lot of moving parts. It's more like to 394 00:19:59,280 --> 00:20:03,160 Speaker 1: the ninth power or something. It's pretty ridiculous little dance 395 00:20:03,200 --> 00:20:05,640 Speaker 1: of machines that we have to get working all together 396 00:20:05,920 --> 00:20:08,600 Speaker 1: to get those rocks back from Mars. And you know 397 00:20:08,760 --> 00:20:11,359 Speaker 1: what you just said, Nobody has ever done that before. 398 00:20:11,640 --> 00:20:15,080 Speaker 1: We've never successfully launched a rocket from the surface of 399 00:20:15,160 --> 00:20:17,520 Speaker 1: another planet. Right, Well, we've done it for the Moon, 400 00:20:17,600 --> 00:20:19,720 Speaker 1: but the Moon is kind of easy to take off from. 401 00:20:19,880 --> 00:20:21,880 Speaker 1: That's right. The Moon is pretty low gravity, and it's 402 00:20:21,920 --> 00:20:24,920 Speaker 1: not a planet, and it's not remote, right, there's somebody 403 00:20:24,960 --> 00:20:27,240 Speaker 1: in there driving that thing. So now we have to 404 00:20:27,480 --> 00:20:31,280 Speaker 1: remotely launch from the service of another planet. I mean, 405 00:20:31,359 --> 00:20:33,720 Speaker 1: that's hard enough to do from Earth. So yeah, it's 406 00:20:33,720 --> 00:20:36,560 Speaker 1: a big challenge. Luckily you volunteered to go tomorrows right now. 407 00:20:36,560 --> 00:20:38,720 Speaker 1: I volunteered to press the big red button. When the 408 00:20:38,760 --> 00:20:42,320 Speaker 1: time comes, Oh yeah, first to take off, to take 409 00:20:42,320 --> 00:20:44,679 Speaker 1: a button or the Abordan whatever. Man just put a 410 00:20:44,680 --> 00:20:46,240 Speaker 1: big red button in front of me and I will 411 00:20:46,320 --> 00:20:50,560 Speaker 1: hit it. That's my job. That's how these podcasts get started. 412 00:20:51,160 --> 00:20:52,880 Speaker 1: You hit a big red button. Hey, you don't get 413 00:20:52,880 --> 00:20:54,480 Speaker 1: to live your dream if you don't ask for it. 414 00:20:54,560 --> 00:20:57,520 Speaker 1: So this is my official request to get invited to 415 00:20:57,520 --> 00:21:01,439 Speaker 1: press the big red button NASA button pusher. All right, 416 00:21:01,480 --> 00:21:03,840 Speaker 1: but you've actually tried before, Like, this is not a 417 00:21:03,880 --> 00:21:05,919 Speaker 1: crazy idea that you and I just came up with 418 00:21:05,960 --> 00:21:08,359 Speaker 1: here on the podcast. The US the Soviets have been 419 00:21:08,359 --> 00:21:12,440 Speaker 1: trying to do this for really like fifty years. Yeah, 420 00:21:12,480 --> 00:21:14,919 Speaker 1: and they've been trying and failing. But the failures have 421 00:21:15,000 --> 00:21:18,119 Speaker 1: been political and financial. It's not like we've sent a 422 00:21:18,160 --> 00:21:21,080 Speaker 1: mission that's attempted to do this and then not succeeded. 423 00:21:21,400 --> 00:21:24,480 Speaker 1: The mission has been thought up and planned and organized 424 00:21:24,520 --> 00:21:28,000 Speaker 1: and then canceled many times in the past. The Soviets 425 00:21:28,119 --> 00:21:30,359 Speaker 1: thought about in the seventies, but they couldn't get their 426 00:21:30,400 --> 00:21:33,880 Speaker 1: rockets to work. NASA had a plan in nineteen seventy 427 00:21:33,960 --> 00:21:37,600 Speaker 1: nine that was canceled because it was too complicated. And 428 00:21:37,640 --> 00:21:42,000 Speaker 1: then recently NASA and the European Space Agency had a 429 00:21:42,000 --> 00:21:44,240 Speaker 1: plan that was in twenty twelve that people thought was 430 00:21:44,280 --> 00:21:46,800 Speaker 1: going to happen, but then it was aborted again because 431 00:21:46,800 --> 00:21:50,520 Speaker 1: it was too complicated and too expensive. This cancel culture 432 00:21:50,600 --> 00:21:52,560 Speaker 1: is out of hand. Daniel, Yeah, and I think that 433 00:21:52,720 --> 00:21:56,480 Speaker 1: especially was really traumatic for the sort of Mars science community. 434 00:21:56,480 --> 00:21:58,720 Speaker 1: People really believed that that one was going to be 435 00:21:58,760 --> 00:22:00,920 Speaker 1: the one. It was finally going to come to fruition. 436 00:22:01,320 --> 00:22:02,879 Speaker 1: So when that was canceled it was a bit like 437 00:22:02,920 --> 00:22:05,800 Speaker 1: the super Conducting super Collider was for particle physics. It 438 00:22:05,880 --> 00:22:08,480 Speaker 1: left a bit of like PTSD on the community. There 439 00:22:08,560 --> 00:22:11,080 Speaker 1: a little bit more cynicism than there was before. So 440 00:22:11,400 --> 00:22:14,320 Speaker 1: it sounds like people get excited about it, they start 441 00:22:14,400 --> 00:22:16,800 Speaker 1: the program, but then they realize it's too hard, so 442 00:22:16,920 --> 00:22:19,879 Speaker 1: they cancel. It is that, and it's happened over and over. 443 00:22:20,119 --> 00:22:22,480 Speaker 1: It's a little bit of a political problem though, because 444 00:22:22,480 --> 00:22:25,400 Speaker 1: it's one of these projects that takes years or decades 445 00:22:25,440 --> 00:22:28,640 Speaker 1: to pull off. So even if you're committed to spending 446 00:22:28,680 --> 00:22:31,560 Speaker 1: a lot of money over many years, you need all 447 00:22:31,560 --> 00:22:34,160 Speaker 1: the people who are in charge after you to stay 448 00:22:34,200 --> 00:22:37,520 Speaker 1: committed to not have their priorities changed, and so it 449 00:22:37,640 --> 00:22:41,040 Speaker 1: takes consistent support over many, many years for this kind 450 00:22:41,080 --> 00:22:43,560 Speaker 1: of thing to actually happen. All right, So there was 451 00:22:43,600 --> 00:22:46,840 Speaker 1: a big program at NASA that got canceled in twelve 452 00:22:47,000 --> 00:22:49,560 Speaker 1: but now now it's sort of been revived. Right now, 453 00:22:49,600 --> 00:22:52,760 Speaker 1: there is some activity at NASA to actually do this. 454 00:22:53,040 --> 00:22:55,480 Speaker 1: That's right, it has been revived. There's a new plan, 455 00:22:56,000 --> 00:22:59,280 Speaker 1: and it's a pretty reasonable plan in comparison with the 456 00:22:59,320 --> 00:23:02,320 Speaker 1: other crazy plans, although I think you'll still find it 457 00:23:02,400 --> 00:23:06,639 Speaker 1: fairly absurd and amazing. This is the level headed conservative 458 00:23:06,960 --> 00:23:10,080 Speaker 1: This is the least ridiculous plan that we have going. 459 00:23:10,240 --> 00:23:12,600 Speaker 1: So how they pitched it to to Congress. We have 460 00:23:12,640 --> 00:23:15,840 Speaker 1: a new, less ridiculous plan. You guys are gonna love 461 00:23:15,840 --> 00:23:19,679 Speaker 1: it now, less crazy. And the most exciting part is 462 00:23:19,720 --> 00:23:22,359 Speaker 1: that the first part of it has already launched. Like 463 00:23:22,440 --> 00:23:25,920 Speaker 1: the first element of this multi stage plan to bring 464 00:23:26,000 --> 00:23:28,679 Speaker 1: rocks back from the service of Mars is already on 465 00:23:28,800 --> 00:23:33,080 Speaker 1: its way to the red plan. Wait, what is this 466 00:23:33,119 --> 00:23:35,960 Speaker 1: is already happening. It's already happening. They have a new 467 00:23:36,000 --> 00:23:38,920 Speaker 1: clever strategy, which is they break it up into pieces 468 00:23:39,359 --> 00:23:42,159 Speaker 1: and so they're easier to sell. And the first piece 469 00:23:42,200 --> 00:23:44,240 Speaker 1: works no matter what, Like, the first piece is something 470 00:23:44,280 --> 00:23:45,720 Speaker 1: you want to do, even if you're not going to 471 00:23:45,800 --> 00:23:49,880 Speaker 1: bring the rocks back. Oh, I see they're cleverer now 472 00:23:49,920 --> 00:23:52,960 Speaker 1: about the mission planning. Yeah, they're a little bit more cynical, 473 00:23:53,119 --> 00:23:55,280 Speaker 1: I guess you could say, or more experienced. And so 474 00:23:55,320 --> 00:23:58,640 Speaker 1: this first piece is a rover that launched on July's 475 00:23:58,720 --> 00:24:02,000 Speaker 1: the Perseverance Rover here, and it's a this year, yeah, 476 00:24:02,119 --> 00:24:04,520 Speaker 1: just a few weeks ago, and it's on the way 477 00:24:04,600 --> 00:24:07,600 Speaker 1: to Mars now. And it's an awesome piece of technology. 478 00:24:07,680 --> 00:24:09,240 Speaker 1: You may have heard about it. It's going to be 479 00:24:09,280 --> 00:24:12,240 Speaker 1: the heaviest rover ever landed on Mars. It's going to 480 00:24:12,320 --> 00:24:15,080 Speaker 1: have a little helicopter on the top of it that 481 00:24:15,160 --> 00:24:18,080 Speaker 1: can fly up the first helicopter operate on the surface 482 00:24:18,080 --> 00:24:20,320 Speaker 1: of Mars. That is so sci fi. Yeah, it's gonna 483 00:24:20,359 --> 00:24:22,280 Speaker 1: be really cool. It's have a little laser on it. 484 00:24:22,600 --> 00:24:25,520 Speaker 1: But most importantly, it's going to have a device that 485 00:24:25,640 --> 00:24:29,280 Speaker 1: can drill into the surface of Mars and extract cores, 486 00:24:29,600 --> 00:24:32,000 Speaker 1: which it can then store in a little sample container. 487 00:24:32,920 --> 00:24:35,880 Speaker 1: I feel like now we're getting to really transform or territory, 488 00:24:36,000 --> 00:24:38,840 Speaker 1: you know, like we're sending a box and then when 489 00:24:38,880 --> 00:24:42,480 Speaker 1: the box lands, it's gonna transform into a drilling machine 490 00:24:42,480 --> 00:24:46,920 Speaker 1: with lasers and a helicopter. That's right, it's Optimist Prime. 491 00:24:47,000 --> 00:24:49,240 Speaker 1: That's what they should have called it. That's right. Forget 492 00:24:49,280 --> 00:24:52,720 Speaker 1: Perseverance or something inspiring. Just go with optimist prime. Yeah, 493 00:24:52,800 --> 00:24:54,840 Speaker 1: So this thing is going to have a year's long 494 00:24:54,880 --> 00:24:57,040 Speaker 1: mission and it's going to drive around and it's going 495 00:24:57,080 --> 00:25:00,040 Speaker 1: to collect like rock course from maybe thirty nine in 496 00:25:00,280 --> 00:25:03,119 Speaker 1: different locations. And each one is pretty small, you know, 497 00:25:03,160 --> 00:25:06,480 Speaker 1: they're like a centimeter wide and a few centimeters long. 498 00:25:06,560 --> 00:25:09,600 Speaker 1: But that's gold for scientists down here. To have a 499 00:25:09,640 --> 00:25:14,320 Speaker 1: few cubic centimeters of rock from several dozen locations around Mars, 500 00:25:14,680 --> 00:25:17,199 Speaker 1: it's incredibly valuable. So it is a rover like the 501 00:25:17,200 --> 00:25:19,879 Speaker 1: ones we've sent before, and it's going to run around 502 00:25:20,200 --> 00:25:22,600 Speaker 1: and collect samples and then keep them keep them in 503 00:25:22,720 --> 00:25:25,320 Speaker 1: like a box. So it's got its own science mission. 504 00:25:25,359 --> 00:25:28,280 Speaker 1: It's a good idea anyway, even if mar sample return 505 00:25:28,640 --> 00:25:31,280 Speaker 1: doesn't happen. But then it's going to collect these rocks 506 00:25:31,320 --> 00:25:33,119 Speaker 1: and it's going to put them in a little sample 507 00:25:33,119 --> 00:25:35,199 Speaker 1: container and then it's going to leave them on the 508 00:25:35,200 --> 00:25:38,640 Speaker 1: surface of Mars for the next stage to come and retrieve. 509 00:25:38,760 --> 00:25:42,560 Speaker 1: Wait what it's going to be littering. It's going to 510 00:25:42,640 --> 00:25:46,080 Speaker 1: be preparing a gift for us. Man, it's not trash, 511 00:25:46,600 --> 00:25:49,640 Speaker 1: but why not collect them? But it's gonna really leave 512 00:25:49,680 --> 00:25:51,600 Speaker 1: them out where it would find them. Yeah, it's going 513 00:25:51,640 --> 00:25:53,359 Speaker 1: to steal up in tubes and then it's going to 514 00:25:53,520 --> 00:25:56,159 Speaker 1: leave it out where the next mission can come and 515 00:25:56,200 --> 00:25:58,240 Speaker 1: collect it. But why not bring them all together so 516 00:25:58,280 --> 00:26:00,159 Speaker 1: that it's easier to pick up. No, it's going to 517 00:26:00,320 --> 00:26:02,800 Speaker 1: collect them all into one container. Oh, I see, and 518 00:26:02,800 --> 00:26:06,320 Speaker 1: then leaves the container there, sees it all nice, and 519 00:26:06,359 --> 00:26:08,440 Speaker 1: then the next stage is going to come and pick 520 00:26:08,480 --> 00:26:10,720 Speaker 1: it up. And so if you're keeping track, there's three 521 00:26:10,920 --> 00:26:14,760 Speaker 1: major stages to this mission. Stage one is perseverance. Go 522 00:26:14,880 --> 00:26:17,600 Speaker 1: and create the samples, pack them up in the container, 523 00:26:17,800 --> 00:26:20,359 Speaker 1: leave it on the surface. It's also going to study them, 524 00:26:20,400 --> 00:26:23,160 Speaker 1: but also going to leave them there. Okay. The next 525 00:26:23,200 --> 00:26:26,040 Speaker 1: stage is to get it off the surface of Mars, 526 00:26:26,640 --> 00:26:29,159 Speaker 1: all right, And each of these is like a different mission. 527 00:26:29,359 --> 00:26:30,840 Speaker 1: It's kind of I think that's when you're saying, like, 528 00:26:31,280 --> 00:26:33,560 Speaker 1: don't put it all in one mission that could fail, 529 00:26:33,720 --> 00:26:35,919 Speaker 1: but do one mission and if that one succeeds, then 530 00:26:35,960 --> 00:26:37,879 Speaker 1: do the next mission, and that one succeeds to the 531 00:26:37,880 --> 00:26:41,000 Speaker 1: next mission. Yes, So there's three separate launches from Earth, 532 00:26:41,080 --> 00:26:44,919 Speaker 1: Like we're sending three different devices from Earth. They're all 533 00:26:45,000 --> 00:26:48,160 Speaker 1: going to work together to make this happen. Three different transformers. 534 00:26:48,920 --> 00:26:51,200 Speaker 1: The first one lands on the service and makes these samples. 535 00:26:51,400 --> 00:26:54,800 Speaker 1: The next one is I think maybe the craziest, and 536 00:26:55,040 --> 00:26:56,800 Speaker 1: it's the one that's going to land on the surface 537 00:26:56,840 --> 00:26:59,840 Speaker 1: of Mars and then it's going to deploy a mini rover, 538 00:27:00,200 --> 00:27:03,280 Speaker 1: like a little rover that just runs out, picks up 539 00:27:03,280 --> 00:27:09,000 Speaker 1: the sample container, comes back, loads that into a rocket 540 00:27:09,400 --> 00:27:12,520 Speaker 1: that it has landed on the surface of Mars, wraps 541 00:27:12,520 --> 00:27:15,800 Speaker 1: out all up, and then launches from the surface of Mars, 542 00:27:16,200 --> 00:27:19,960 Speaker 1: sends the sample container up into space. So on a 543 00:27:20,040 --> 00:27:23,280 Speaker 1: rocket will be sending another rocket and a launching pad, 544 00:27:23,640 --> 00:27:26,240 Speaker 1: and a launching pad and a little tiny retriever robot 545 00:27:26,320 --> 00:27:29,520 Speaker 1: and a mini rover. Yeah, exactly. So the job of 546 00:27:29,560 --> 00:27:31,919 Speaker 1: this thing is to land there, pick up the sample 547 00:27:32,000 --> 00:27:34,560 Speaker 1: container and it has a robotic arm that will take 548 00:27:34,600 --> 00:27:37,199 Speaker 1: it from the rover and put it into the rocket 549 00:27:37,560 --> 00:27:41,200 Speaker 1: and then yeah, remote launch from the surface of another planet. 550 00:27:41,359 --> 00:27:45,600 Speaker 1: Maybe the most valuable sample ever to be collected. This 551 00:27:45,680 --> 00:27:48,159 Speaker 1: feels kind of comical to me, like, you know, like 552 00:27:48,200 --> 00:27:51,720 Speaker 1: this giant machine lands, opens up up, there's another rocket 553 00:27:51,760 --> 00:27:56,000 Speaker 1: in there. This little robot comes out, picks up something, 554 00:27:56,200 --> 00:27:59,479 Speaker 1: runs back, sticks it in the rocket, and then just 555 00:27:59,600 --> 00:28:03,160 Speaker 1: launches back somehow that it feels comedic, something like something 556 00:28:03,200 --> 00:28:06,000 Speaker 1: out of a cartoon. It does seem a little Looney Tunes. Yeah, 557 00:28:06,080 --> 00:28:08,640 Speaker 1: you're right, and if this thing works, it definitely needs 558 00:28:08,720 --> 00:28:12,120 Speaker 1: that sort of like comedic music in the background to inspire. 559 00:28:11,920 --> 00:28:17,840 Speaker 1: You know, it'll be pretty funny. But this is not 560 00:28:17,960 --> 00:28:20,879 Speaker 1: set to go for another five years or so, So 561 00:28:20,920 --> 00:28:26,000 Speaker 1: we're talking about launching this next bit in six So wait, 562 00:28:26,040 --> 00:28:27,680 Speaker 1: so there must be working on it now, like it's 563 00:28:27,720 --> 00:28:30,720 Speaker 1: being built right now. It's being built right now, So 564 00:28:31,200 --> 00:28:34,000 Speaker 1: Perseverance will have years on the surface of Mars to 565 00:28:34,080 --> 00:28:36,879 Speaker 1: collect these samples. And also we'll have an idea like 566 00:28:37,000 --> 00:28:39,680 Speaker 1: how did that go right, how well are things going? 567 00:28:39,960 --> 00:28:42,440 Speaker 1: We could change our plan based on where Perseverance is 568 00:28:42,560 --> 00:28:44,880 Speaker 1: or how things go for Perseverance, or what it learns, 569 00:28:44,960 --> 00:28:47,920 Speaker 1: or how the sample container looks um and so that's 570 00:28:48,080 --> 00:28:49,960 Speaker 1: another part of it. You build in these delays so 571 00:28:50,040 --> 00:28:53,440 Speaker 1: you can change your plans as things develop. So, yeah, 572 00:28:53,440 --> 00:28:55,600 Speaker 1: they're working on that now and they will launch it 573 00:28:55,600 --> 00:28:58,959 Speaker 1: in and the ideas they would arrive on the surface 574 00:28:59,000 --> 00:29:01,400 Speaker 1: of Mars in twenty twenty eight. Remember it's a two 575 00:29:01,480 --> 00:29:04,440 Speaker 1: year trip, and then grab it and launch it out 576 00:29:04,520 --> 00:29:07,240 Speaker 1: into space. But it only has the power to get 577 00:29:07,240 --> 00:29:09,960 Speaker 1: it into orbit around Mars. It can't bring all the 578 00:29:10,000 --> 00:29:13,320 Speaker 1: way back to Earth. Oh, that's still just phase two. 579 00:29:13,640 --> 00:29:16,959 Speaker 1: That's just phase two, right, The actual looney Tunes crazy 580 00:29:17,000 --> 00:29:20,640 Speaker 1: comedic value comes in the next day. All right, let's say, 581 00:29:20,680 --> 00:29:23,080 Speaker 1: let's phase three. So phase three as we launch a 582 00:29:23,240 --> 00:29:26,840 Speaker 1: third rocket from Earth and this one at the same 583 00:29:26,880 --> 00:29:29,080 Speaker 1: time as we're launching the second one, but this one 584 00:29:29,160 --> 00:29:32,160 Speaker 1: just stays in orbit around Mars. This is called the 585 00:29:32,200 --> 00:29:35,200 Speaker 1: Earth return orbiter. So this one is a concurrent, like 586 00:29:35,240 --> 00:29:37,240 Speaker 1: we're not gonna wait for the second one to finish. 587 00:29:37,440 --> 00:29:39,400 Speaker 1: We're gonna send two and three. It's like filming the 588 00:29:39,680 --> 00:29:43,000 Speaker 1: sequels at the same time. Yeah, exactly. So the third 589 00:29:43,040 --> 00:29:45,479 Speaker 1: one hangs at in orbit and it helps communicate and 590 00:29:45,480 --> 00:29:48,400 Speaker 1: do a bunch of stuff. And then it's most important 591 00:29:48,480 --> 00:29:52,920 Speaker 1: job is to catch the sample container. Because the surface 592 00:29:53,040 --> 00:29:55,479 Speaker 1: rocket is going to launch from the surface of Mars 593 00:29:56,080 --> 00:29:59,400 Speaker 1: and get out near orbit. Right, it can't go all 594 00:29:59,440 --> 00:30:01,840 Speaker 1: the way out actually out into space, and the one 595 00:30:01,880 --> 00:30:05,080 Speaker 1: that's in orbit has to lower itself down to lower orbit. 596 00:30:05,680 --> 00:30:08,160 Speaker 1: And then they're going to pass the sample container from 597 00:30:08,240 --> 00:30:11,560 Speaker 1: one rocket to the orbiter. Robots are going to do this. 598 00:30:11,720 --> 00:30:16,600 Speaker 1: Robots are going to do this in space, you know, 599 00:30:16,680 --> 00:30:19,800 Speaker 1: Sending Daniel is starting to seem a lot easier, I know. 600 00:30:20,320 --> 00:30:23,560 Speaker 1: And the sample container it has no like radio beacon, 601 00:30:23,800 --> 00:30:26,800 Speaker 1: has no tracker on it has no transmitter, has no thrusters, 602 00:30:27,120 --> 00:30:30,560 Speaker 1: is just an inert white ball and the orbiter just 603 00:30:30,600 --> 00:30:33,120 Speaker 1: has to catch it. Doesn't have like a GPS on 604 00:30:33,160 --> 00:30:37,160 Speaker 1: it even or it's just white. They're like, let's make 605 00:30:37,160 --> 00:30:41,800 Speaker 1: it white then you can see it in space. Right. Wow, 606 00:30:41,840 --> 00:30:44,360 Speaker 1: that is audacious to say the least. But I guess 607 00:30:44,400 --> 00:30:46,640 Speaker 1: my question is why can't the rocket just go straight 608 00:30:46,680 --> 00:30:49,680 Speaker 1: into orbit? You can't put in a fuel on it 609 00:30:49,800 --> 00:30:51,880 Speaker 1: or something or what. That definitely takes a lot more 610 00:30:51,880 --> 00:30:54,120 Speaker 1: power to get all the way into orbit. And so yeah, 611 00:30:54,160 --> 00:30:55,800 Speaker 1: I mean you have to launch this thing from Earth 612 00:30:55,840 --> 00:30:57,920 Speaker 1: and then send it to Mars. And so there's a 613 00:30:58,000 --> 00:31:00,400 Speaker 1: lot of risks and costs here that they're trying to balance. 614 00:31:00,480 --> 00:31:04,320 Speaker 1: And this was what they decided was the least crazy plan. 615 00:31:05,880 --> 00:31:08,400 Speaker 1: I guess it would be a lot to like land 616 00:31:08,520 --> 00:31:10,320 Speaker 1: a rocket that can make it all the way back 617 00:31:10,360 --> 00:31:13,040 Speaker 1: to Earth. I guess this is smartyr to like, you know, 618 00:31:13,240 --> 00:31:17,040 Speaker 1: make this rocket smaller and then save the spaceship part 619 00:31:17,040 --> 00:31:20,200 Speaker 1: of it for another phase. Yeah, and now the part 620 00:31:20,280 --> 00:31:22,840 Speaker 1: the orbiter only ever has to live in space. It 621 00:31:22,880 --> 00:31:24,840 Speaker 1: doesn't have to go down to the surface. So you 622 00:31:24,880 --> 00:31:27,240 Speaker 1: have one thing that's dedicated to going down to the surface, 623 00:31:27,280 --> 00:31:29,640 Speaker 1: it's good at that, and another thing that's dedicated at 624 00:31:29,880 --> 00:31:33,520 Speaker 1: orbiting Mars, catching this soccer ball with the most valuable 625 00:31:33,560 --> 00:31:37,360 Speaker 1: cargo humans have ever created, and then flying on its 626 00:31:37,360 --> 00:31:39,600 Speaker 1: own all the way back to Earth. It sounds like, 627 00:31:39,640 --> 00:31:41,640 Speaker 1: you know, kind of like a whole bunch of robots 628 00:31:41,680 --> 00:31:44,480 Speaker 1: that together make one big robot. Yeah, it's a bit 629 00:31:44,480 --> 00:31:46,520 Speaker 1: of a Rube Goldberg machine. Right. They should have called 630 00:31:46,520 --> 00:31:50,320 Speaker 1: this the Rube Goldberg Mars Mission. It's pretty hilarious. All right. Well, 631 00:31:50,400 --> 00:31:55,800 Speaker 1: let's get into what happens next phase three, but first 632 00:31:55,880 --> 00:32:10,479 Speaker 1: let's take a quick break. All right, Daniel, we are 633 00:32:10,520 --> 00:32:15,200 Speaker 1: talking about transformers in Mars and robots that we're gonna 634 00:32:15,280 --> 00:32:18,840 Speaker 1: send there and work together on their own to land 635 00:32:18,840 --> 00:32:22,040 Speaker 1: on Mars, get some rocks, shoot them back up into space, 636 00:32:22,440 --> 00:32:24,880 Speaker 1: hand it off, and then bring it back. So that's 637 00:32:24,920 --> 00:32:28,720 Speaker 1: phase three, is bringing the samples from Mars. Fact, that's right, 638 00:32:28,760 --> 00:32:31,320 Speaker 1: that's phase three. So it has to catch this soccer 639 00:32:31,360 --> 00:32:34,880 Speaker 1: ball in orbit around Mars. Right, it like opens a 640 00:32:35,000 --> 00:32:36,880 Speaker 1: door on the side of the ship and the ball 641 00:32:36,960 --> 00:32:40,000 Speaker 1: just like drifts in because remember the ball is not powered, 642 00:32:40,320 --> 00:32:42,600 Speaker 1: so it just has to like match it in orbital 643 00:32:42,640 --> 00:32:44,280 Speaker 1: speed and get in front of it and then slow 644 00:32:44,360 --> 00:32:46,600 Speaker 1: down a little bit and just sort of like mate 645 00:32:46,600 --> 00:32:50,080 Speaker 1: with this thing. Yeah, it's gonna catch it. It's gonna 646 00:32:50,120 --> 00:32:54,120 Speaker 1: catch it, and it has to then keep it somehow sterile. 647 00:32:54,160 --> 00:32:57,320 Speaker 1: It can't like let the sample contain or anything that 648 00:32:57,440 --> 00:33:00,800 Speaker 1: was on it infect the rest of the ship. Oh 649 00:33:00,840 --> 00:33:03,720 Speaker 1: I see. It had to catch it and isolated, catch 650 00:33:03,760 --> 00:33:07,400 Speaker 1: it and isolated fly it all the way back to Earth. Right, 651 00:33:07,440 --> 00:33:09,040 Speaker 1: that's not that big a deal. You just had sort 652 00:33:09,040 --> 00:33:11,440 Speaker 1: of point in the right direction and have enough power left. 653 00:33:11,880 --> 00:33:15,080 Speaker 1: And then it has to drop it off on Earth. Wow, 654 00:33:15,120 --> 00:33:16,840 Speaker 1: I'm just gonna drop it off or it's gonna land. 655 00:33:16,920 --> 00:33:18,560 Speaker 1: It's not gonna land here on Earth. It's just going 656 00:33:18,600 --> 00:33:21,200 Speaker 1: to drop it off, and the sample container is essentially 657 00:33:21,280 --> 00:33:24,440 Speaker 1: just gonna fall to the surface. They were like, should 658 00:33:24,440 --> 00:33:27,520 Speaker 1: we add parachutes or something to slow it down? But 659 00:33:27,960 --> 00:33:31,680 Speaker 1: that seemed too complicated. They're like, no, can't you just 660 00:33:31,760 --> 00:33:35,040 Speaker 1: call like uber to pick it up or build a 661 00:33:35,160 --> 00:33:37,920 Speaker 1: huge catcher's mit or something. Well, why not build another 662 00:33:38,000 --> 00:33:41,200 Speaker 1: robot to go up there and catch it? Why not? Well, 663 00:33:41,240 --> 00:33:43,560 Speaker 1: they thought this was simplest, and you know, they already 664 00:33:43,600 --> 00:33:46,360 Speaker 1: used up their quota of crazy robots on this mission. 665 00:33:46,360 --> 00:33:48,600 Speaker 1: So they're just gonna toss it into what the ocean. No, 666 00:33:48,680 --> 00:33:50,960 Speaker 1: it's gonna land on the surface and land around ninety 667 00:33:51,040 --> 00:33:54,560 Speaker 1: miles per hour on the surface, and it's not going 668 00:33:54,600 --> 00:33:57,280 Speaker 1: to explode or vaporize. It's not going to vaporize that. 669 00:33:57,360 --> 00:33:59,720 Speaker 1: It should be able to survive that. And you know, 670 00:33:59,840 --> 00:34:02,680 Speaker 1: the samples themselves shouldn't be that delicate, right, It's not 671 00:34:02,720 --> 00:34:06,160 Speaker 1: like they're glass containers or you know, anything that's gonna break. 672 00:34:06,240 --> 00:34:08,319 Speaker 1: It's just rocks were bringing back. I thought they were 673 00:34:08,320 --> 00:34:10,040 Speaker 1: going to be on like, you know, test tubes, but 674 00:34:10,080 --> 00:34:13,960 Speaker 1: I guess you want something would have been more sturdy. Yeah, 675 00:34:14,000 --> 00:34:16,880 Speaker 1: But the question is like can we keep it safe 676 00:34:16,920 --> 00:34:20,799 Speaker 1: and contained? We're basically shipping a chunk of mars onto 677 00:34:20,840 --> 00:34:23,080 Speaker 1: the surface of the Earth, and we want to isolate 678 00:34:23,120 --> 00:34:24,880 Speaker 1: it so that we can study it for well a 679 00:34:24,880 --> 00:34:27,239 Speaker 1: couple of reasons. One is like who knows what's in 680 00:34:27,280 --> 00:34:29,319 Speaker 1: that thing? And if there really is like weird life 681 00:34:29,320 --> 00:34:31,239 Speaker 1: on Mars. The last thing we want to do is 682 00:34:31,280 --> 00:34:34,600 Speaker 1: like eradicate all life on Earth because we imported some pathogen. 683 00:34:35,440 --> 00:34:38,040 Speaker 1: Didn't wrap it into plastic bag. First, I've seen that movie. 684 00:34:39,000 --> 00:34:41,640 Speaker 1: It's pretty good unless you're living it. But the other 685 00:34:41,680 --> 00:34:43,359 Speaker 1: thing is we want to keep it sterile so that 686 00:34:43,440 --> 00:34:45,800 Speaker 1: if we do, like find weird bugs in it that 687 00:34:45,920 --> 00:34:47,839 Speaker 1: are similar to bugs on Earth, we want to know 688 00:34:48,000 --> 00:34:50,520 Speaker 1: they came from Mars and not from like the Utah 689 00:34:50,560 --> 00:34:52,719 Speaker 1: Desert where it landed. Wow. Well, this seems like a 690 00:34:52,840 --> 00:34:57,440 Speaker 1: super audacious and amazing and incredible plan. And Daniel, you 691 00:34:57,480 --> 00:34:59,680 Speaker 1: actually got to talk to somebody who works on this 692 00:35:00,000 --> 00:35:02,799 Speaker 1: so ready from NASA. Yeah, there's incredible excitement in the 693 00:35:02,800 --> 00:35:06,160 Speaker 1: community for this project. People are hoping beyond hope that 694 00:35:06,200 --> 00:35:09,080 Speaker 1: they'll get that get their hands on some of these rocks. 695 00:35:09,280 --> 00:35:12,440 Speaker 1: So I reached out to Dr Nina Lanza. She's a 696 00:35:12,480 --> 00:35:15,839 Speaker 1: Mars rover instrument scientist. She built some of the things 697 00:35:15,840 --> 00:35:18,919 Speaker 1: that are going on Perseverance right now, and I asked 698 00:35:18,960 --> 00:35:21,399 Speaker 1: her a bunch of fun questions about this project. Yeah, 699 00:35:21,400 --> 00:35:24,000 Speaker 1: it's a great interview, so we'll play that for you 700 00:35:24,080 --> 00:35:27,400 Speaker 1: right now. So here's Daniel talking to Dr Nina Lanzon 701 00:35:27,920 --> 00:35:31,520 Speaker 1: Mars Rover instrument scientist. So it's my pleasure to be 702 00:35:31,640 --> 00:35:35,600 Speaker 1: talking to Dr Nina Lanza Um. Would you introduce yourself 703 00:35:35,600 --> 00:35:39,080 Speaker 1: for our listeners. Sure, I'm Nina lanza I work at 704 00:35:39,120 --> 00:35:43,200 Speaker 1: Los Alamos National Laboratory and I'm a planetary scientist. Awesome, 705 00:35:43,440 --> 00:35:46,399 Speaker 1: And so our question today are mostly about getting your 706 00:35:46,440 --> 00:35:49,920 Speaker 1: hands on samples from Mars or the signs you can 707 00:35:49,960 --> 00:35:53,160 Speaker 1: do with stuff on Mars. So my first question has 708 00:35:53,200 --> 00:35:55,359 Speaker 1: to do with the rovers that we have over there 709 00:35:55,360 --> 00:35:57,640 Speaker 1: and that we're sending over there. What do you think 710 00:35:57,640 --> 00:36:01,880 Speaker 1: of the most important scientific stens that those instruments on 711 00:36:01,920 --> 00:36:05,719 Speaker 1: the rovers are asking? Well, it's important to remember that 712 00:36:05,800 --> 00:36:09,200 Speaker 1: each of these missions had a different goal and they 713 00:36:09,200 --> 00:36:12,080 Speaker 1: would they build on each other. Right, So, when we 714 00:36:12,120 --> 00:36:15,560 Speaker 1: first started sending rovers to Mars um and and even Landers, 715 00:36:15,719 --> 00:36:17,440 Speaker 1: you know, we didn't know a lot. We know a 716 00:36:17,440 --> 00:36:20,640 Speaker 1: lot more after all the missions we've done. So initial 717 00:36:20,640 --> 00:36:23,000 Speaker 1: missions were just to figure out, you know, what's on Mars, 718 00:36:23,120 --> 00:36:26,960 Speaker 1: what's it like? And subsequent missions have been trying to 719 00:36:27,000 --> 00:36:30,480 Speaker 1: find out the details of that. What has the history 720 00:36:30,480 --> 00:36:32,640 Speaker 1: of Mars been like, you know, in terms of climate, 721 00:36:32,640 --> 00:36:37,120 Speaker 1: in terms of geology. Now we're asking questions about habitability, 722 00:36:37,200 --> 00:36:40,879 Speaker 1: is or was the Martian environment habitable in a way 723 00:36:40,920 --> 00:36:44,240 Speaker 1: that we understand. So habitability is not looking for life, 724 00:36:44,520 --> 00:36:47,400 Speaker 1: but rather places where life as we understand it, could exist. 725 00:36:47,719 --> 00:36:51,160 Speaker 1: And so now after our most recent missions, you know, 726 00:36:51,200 --> 00:36:54,759 Speaker 1: we feel really confident that Mars was absolutely a habitable 727 00:36:54,800 --> 00:36:58,760 Speaker 1: place in the past, and it's kind of habitable now 728 00:36:58,960 --> 00:37:03,480 Speaker 1: for certain arestrial microbes um and so our next goal 729 00:37:03,800 --> 00:37:07,480 Speaker 1: is to find out whether or not life ever existed 730 00:37:07,600 --> 00:37:10,360 Speaker 1: in the past on Mars, and so that's really exciting. 731 00:37:10,719 --> 00:37:13,560 Speaker 1: So I think it's not that one of those questions 732 00:37:13,600 --> 00:37:16,040 Speaker 1: is more or less important. It's really that they are 733 00:37:16,160 --> 00:37:19,239 Speaker 1: building upon each other, and so are the questions that 734 00:37:19,280 --> 00:37:22,480 Speaker 1: are being asked by these rovers or instruments designed for 735 00:37:22,520 --> 00:37:25,280 Speaker 1: these rovers that are inspired specifically by things you learned 736 00:37:25,280 --> 00:37:28,360 Speaker 1: on previous generations, like we saw this and now we 737 00:37:28,360 --> 00:37:31,480 Speaker 1: have a follow up question. Oh certainly, gosh, And there's 738 00:37:31,520 --> 00:37:34,440 Speaker 1: so many examples of that. I mean, there are some 739 00:37:34,480 --> 00:37:38,399 Speaker 1: big questions. For example, we've seen from remote sensing these 740 00:37:38,480 --> 00:37:43,839 Speaker 1: huge mineral provinces, specifically clay minerals and carbonates, maybe less 741 00:37:43,920 --> 00:37:46,440 Speaker 1: huge on the carbonates, right, We've seen these from orbit, 742 00:37:46,840 --> 00:37:48,960 Speaker 1: and so the question is can we ground through this 743 00:37:49,040 --> 00:37:51,799 Speaker 1: and find this on Mars in a geologic context that 744 00:37:51,840 --> 00:37:54,520 Speaker 1: we can interpret. We've certainly found quite a bit of 745 00:37:54,560 --> 00:37:58,600 Speaker 1: clay on the surface with the curiosity rovers, so yeah, success, 746 00:37:59,440 --> 00:38:02,879 Speaker 1: But now we're looking for those pesky carbonates. Carbon rates 747 00:38:02,920 --> 00:38:05,600 Speaker 1: are predicted to have formed on Mars, but we've never 748 00:38:05,640 --> 00:38:08,319 Speaker 1: really encountered them in any kind of abundance, and so 749 00:38:08,400 --> 00:38:11,640 Speaker 1: it's one of these ongoing mysteries. And so as we 750 00:38:11,840 --> 00:38:15,480 Speaker 1: have moved forward looking at Mars and detail with curiosity, 751 00:38:15,600 --> 00:38:17,440 Speaker 1: we still haven't seen all that mighty carbon rates. So 752 00:38:17,440 --> 00:38:21,000 Speaker 1: it's still this question why not, And we're hoping to 753 00:38:21,000 --> 00:38:23,359 Speaker 1: answer that with the perseverance were over and its new 754 00:38:23,440 --> 00:38:26,719 Speaker 1: landing site, Geserro Crater. Cool. So, I know, when you 755 00:38:26,800 --> 00:38:29,720 Speaker 1: start a project, you have sort of like optimistic hopes 756 00:38:29,760 --> 00:38:32,919 Speaker 1: for what you know might happen, or fantasy is about 757 00:38:32,960 --> 00:38:35,359 Speaker 1: data you might collect or whatever. So if you let 758 00:38:35,360 --> 00:38:37,880 Speaker 1: your imagination run wild and you hit all the home runs, 759 00:38:37,960 --> 00:38:40,120 Speaker 1: it's like the best case scenario for what you could 760 00:38:40,120 --> 00:38:44,120 Speaker 1: discover using these rovers. Well, I think it would be 761 00:38:44,360 --> 00:38:48,960 Speaker 1: just incredible and paradigm shifting if we could find signs 762 00:38:49,040 --> 00:38:53,200 Speaker 1: that life existed somewhere not Earth. Right, we know there's 763 00:38:53,239 --> 00:38:55,520 Speaker 1: life on Earth, you know about how did it start? 764 00:38:55,560 --> 00:38:58,000 Speaker 1: We don't really understand a lot about our own origins, 765 00:38:58,560 --> 00:39:00,680 Speaker 1: and we don't know how common it is. Right now, 766 00:39:00,760 --> 00:39:03,560 Speaker 1: we only have one example of life on a planet, 767 00:39:03,600 --> 00:39:06,880 Speaker 1: and that's our planet. If we could find evidence of 768 00:39:06,920 --> 00:39:10,400 Speaker 1: life on a different planet, to be remarkable and incredible, 769 00:39:10,480 --> 00:39:13,240 Speaker 1: what would that look like in terms of the rovers 770 00:39:13,280 --> 00:39:15,360 Speaker 1: that we have now or the rovers that are in route, 771 00:39:15,600 --> 00:39:17,239 Speaker 1: what would that discovery look like? I mean, we're not 772 00:39:17,239 --> 00:39:21,759 Speaker 1: talking about little critters waving to the cameras, right, I mean, 773 00:39:21,800 --> 00:39:24,520 Speaker 1: I think it's pretty clear that there is a macroscopic 774 00:39:24,600 --> 00:39:27,120 Speaker 1: life on Mars right there, trees, There's no dinosaurs. We 775 00:39:27,120 --> 00:39:29,759 Speaker 1: would have seen those things. So now the question is 776 00:39:30,000 --> 00:39:33,640 Speaker 1: microscopic life. Was it there? It isn't there? So those 777 00:39:33,680 --> 00:39:36,440 Speaker 1: are actually two different questions and we have to have 778 00:39:36,520 --> 00:39:40,520 Speaker 1: different approaches to answer those questions. Right. The Perseverance Rover 779 00:39:40,640 --> 00:39:42,880 Speaker 1: is looking for signs of past life and there's a 780 00:39:42,920 --> 00:39:45,160 Speaker 1: lot of ways to do that, and we use the 781 00:39:45,239 --> 00:39:48,000 Speaker 1: same techniques that we do on Earth. How do we 782 00:39:48,080 --> 00:39:50,719 Speaker 1: know when life began on Earth and what were the 783 00:39:50,719 --> 00:39:53,799 Speaker 1: signs that it left? So that's our best way of 784 00:39:53,920 --> 00:39:56,879 Speaker 1: analyzing Mars rocks to find out if there was life 785 00:39:57,000 --> 00:39:59,719 Speaker 1: in the past. I think our best bet, you know, 786 00:40:00,120 --> 00:40:03,560 Speaker 1: he's going to be bringing these samples back to Earth. 787 00:40:04,080 --> 00:40:07,640 Speaker 1: We have some incredible rovers and they're having great hayloads 788 00:40:07,719 --> 00:40:10,279 Speaker 1: of these instruments that just do great things, and they're 789 00:40:10,320 --> 00:40:12,919 Speaker 1: doing them remotely. It's just amazing what we can do. 790 00:40:13,360 --> 00:40:15,840 Speaker 1: But it doesn't compare to our gold standard instruments that 791 00:40:15,880 --> 00:40:18,520 Speaker 1: we have on the Earth, and so there are questions 792 00:40:18,560 --> 00:40:21,279 Speaker 1: that we can never answer with our current hayloads. So 793 00:40:21,320 --> 00:40:23,600 Speaker 1: we're going to need to just get that sample back 794 00:40:23,680 --> 00:40:26,640 Speaker 1: into the laboratory, take a look at it, and then 795 00:40:26,800 --> 00:40:29,200 Speaker 1: we'll probably want to do different analyzes. Right, we don't 796 00:40:29,200 --> 00:40:30,879 Speaker 1: know what we're going to see, and so we don't 797 00:40:30,920 --> 00:40:33,120 Speaker 1: know what the next steps will be. And that's the 798 00:40:33,400 --> 00:40:36,560 Speaker 1: excitement and the fun part about doing science like this 799 00:40:36,680 --> 00:40:40,320 Speaker 1: is that you can only predict the first few steps, 800 00:40:40,400 --> 00:40:43,200 Speaker 1: but it's the next steps are all dependent on what 801 00:40:43,239 --> 00:40:46,120 Speaker 1: you find. And why can't we just do those studies 802 00:40:46,200 --> 00:40:48,520 Speaker 1: on Martian meteors, you know, bits of Mars that have 803 00:40:48,560 --> 00:40:51,600 Speaker 1: been blasted off and landed here already. We're very lucky 804 00:40:51,600 --> 00:40:54,320 Speaker 1: that Mars has sent us about hundred and fifty pieces 805 00:40:54,320 --> 00:40:56,560 Speaker 1: of itself. So we didn't actually have to go to 806 00:40:56,600 --> 00:40:59,560 Speaker 1: Mars to get those pieces of Mars. So thank you Mars. 807 00:41:00,120 --> 00:41:03,520 Speaker 1: The problem with those meteorites, though, is that they don't 808 00:41:03,560 --> 00:41:06,520 Speaker 1: have any context. Right, they fell out of the sky. 809 00:41:06,760 --> 00:41:09,960 Speaker 1: We don't know where they came from on Mars. It's 810 00:41:10,080 --> 00:41:14,200 Speaker 1: very hard to make statements about geology and a broad 811 00:41:14,239 --> 00:41:17,040 Speaker 1: sense if you only have a hand sample. Right. As 812 00:41:17,040 --> 00:41:19,279 Speaker 1: a geologist, people come to me all the time with 813 00:41:19,360 --> 00:41:21,759 Speaker 1: some random rocks. They're like, what's this. I'm like, well, 814 00:41:22,000 --> 00:41:25,080 Speaker 1: I could tell you some things, but you know, you 815 00:41:25,160 --> 00:41:26,680 Speaker 1: just picked that up off of the ground. Where did 816 00:41:26,680 --> 00:41:29,080 Speaker 1: it come from? What was the broader context? We need 817 00:41:29,120 --> 00:41:31,880 Speaker 1: that context to really be able to answer these questions 818 00:41:31,880 --> 00:41:34,840 Speaker 1: about Mars. That's why sample return is so exciting because 819 00:41:34,880 --> 00:41:38,360 Speaker 1: we know exactly where it came from. We have documented 820 00:41:38,400 --> 00:41:41,040 Speaker 1: that location very well, and so then when we get 821 00:41:41,080 --> 00:41:44,319 Speaker 1: results from that sample, we can then integrate that into 822 00:41:44,400 --> 00:41:47,239 Speaker 1: a larger context. That makes a lot of sense. And 823 00:41:47,280 --> 00:41:50,439 Speaker 1: so if there are creators alive on Mars and little 824 00:41:50,480 --> 00:41:53,960 Speaker 1: microubs and we sample them by chance and those samples 825 00:41:53,960 --> 00:41:57,240 Speaker 1: come back to Earth, they are we imagining that those 826 00:41:57,280 --> 00:42:00,719 Speaker 1: things could still be you know, alive and wiggling. We 827 00:42:00,760 --> 00:42:03,719 Speaker 1: measure like you know, metabolic activity in the sample that 828 00:42:03,800 --> 00:42:06,440 Speaker 1: returns to Earth from Mars. If there are things living 829 00:42:06,480 --> 00:42:08,480 Speaker 1: near the surface of Mars, they have got to be 830 00:42:08,560 --> 00:42:12,560 Speaker 1: amazing because the radiation environment on Mars is terrible. You know, 831 00:42:12,680 --> 00:42:15,920 Speaker 1: it's um Mars doesn't have a magnetic field because it 832 00:42:15,960 --> 00:42:18,640 Speaker 1: doesn't have a dynamo in its core, and so the 833 00:42:18,680 --> 00:42:21,919 Speaker 1: surface environment is just it's pretty icky for life. There's 834 00:42:21,920 --> 00:42:24,160 Speaker 1: a lot of life on Earth that could probably handle it, 835 00:42:24,160 --> 00:42:26,759 Speaker 1: but it's it's not that common. So so I would 836 00:42:26,800 --> 00:42:31,600 Speaker 1: say the chances of us finding extant Martians in the 837 00:42:31,680 --> 00:42:34,000 Speaker 1: near subsurface where we can access it with the rover, 838 00:42:34,120 --> 00:42:37,480 Speaker 1: it's very, very low. But we have to prepare for 839 00:42:37,560 --> 00:42:41,880 Speaker 1: that possibility. So one of the things that's really critical 840 00:42:41,920 --> 00:42:44,279 Speaker 1: that we do before our samples come back is to 841 00:42:44,320 --> 00:42:48,759 Speaker 1: prepare their housing facility. There are a few facilities on 842 00:42:48,840 --> 00:42:51,120 Speaker 1: Earth that already are ready for this. A notable one 843 00:42:51,400 --> 00:42:55,279 Speaker 1: is at Johnson Space Center, which is the main pository 844 00:42:55,320 --> 00:42:57,600 Speaker 1: for all the Apollo samples from the Moon. Because we 845 00:42:57,640 --> 00:42:59,560 Speaker 1: had the same questions about the Moon, you know, who 846 00:42:59,560 --> 00:43:01,799 Speaker 1: knows what's up there? And it turns out that the 847 00:43:01,840 --> 00:43:04,360 Speaker 1: Moon is a pretty sterile place which was out and 848 00:43:04,400 --> 00:43:07,400 Speaker 1: maybe that was easy to predict in in retrospect, but 849 00:43:07,400 --> 00:43:09,040 Speaker 1: you know, we had no idea, so we had to 850 00:43:09,080 --> 00:43:12,799 Speaker 1: take really a lot of precautions to protect both the 851 00:43:12,840 --> 00:43:15,719 Speaker 1: samples and earth from each other. And so we'll have 852 00:43:15,760 --> 00:43:18,720 Speaker 1: to do the same for a MAR sample return mission. 853 00:43:19,200 --> 00:43:22,040 Speaker 1: And so we know from our experience with Apollo and 854 00:43:22,120 --> 00:43:25,200 Speaker 1: also just bioscience in general, you know the best methods 855 00:43:25,239 --> 00:43:27,759 Speaker 1: for doing that. And so I think that facilities are 856 00:43:27,760 --> 00:43:31,319 Speaker 1: going to either be constructed or old ones retrofitted to 857 00:43:31,320 --> 00:43:34,000 Speaker 1: be able to handle these new samples. Awesome. Well, I 858 00:43:34,040 --> 00:43:37,000 Speaker 1: hope that happens. I've been reading a little bit about 859 00:43:37,000 --> 00:43:40,640 Speaker 1: the history of these missions, and I note that you know, 860 00:43:40,719 --> 00:43:44,239 Speaker 1: MAR sample return has been discussed for decades and even 861 00:43:44,320 --> 00:43:47,480 Speaker 1: planned and then canceled and replanned and recanceled. Do you 862 00:43:47,520 --> 00:43:50,759 Speaker 1: think this latest plan by NASA and s A is 863 00:43:50,960 --> 00:43:53,520 Speaker 1: likely to actually happen or do you think the political 864 00:43:53,560 --> 00:43:57,800 Speaker 1: climate where we change administrations and government every few years 865 00:43:57,840 --> 00:44:00,680 Speaker 1: makes it difficult to pull off a long term product. Well, 866 00:44:00,719 --> 00:44:03,440 Speaker 1: it's certainly above my pay grade to make political predictions, 867 00:44:03,480 --> 00:44:07,120 Speaker 1: so I can't really speak to that, but um, it's true. 868 00:44:07,200 --> 00:44:11,440 Speaker 1: That these missions are really big, they require incredible amounts 869 00:44:11,440 --> 00:44:14,280 Speaker 1: of collaboration over long periods of time, and they require 870 00:44:14,360 --> 00:44:17,319 Speaker 1: quite a bit of funding. So that is what we 871 00:44:17,360 --> 00:44:20,200 Speaker 1: need the most. I don't think that anything is impossible 872 00:44:20,239 --> 00:44:22,840 Speaker 1: for us if we work together. I think that we've 873 00:44:23,040 --> 00:44:24,719 Speaker 1: really come up with a great plan that has a 874 00:44:24,800 --> 00:44:28,000 Speaker 1: high likelihood of success. The question is whether or not 875 00:44:28,080 --> 00:44:30,680 Speaker 1: we want to fund that, and that's not up to 876 00:44:30,680 --> 00:44:32,920 Speaker 1: to me as an individual. If it were would be 877 00:44:32,960 --> 00:44:34,839 Speaker 1: funded right now, but you know, we have to make 878 00:44:34,880 --> 00:44:39,000 Speaker 1: sure that this is aligned with our taxpayers desires. Um 879 00:44:39,000 --> 00:44:40,640 Speaker 1: there's a lot of things that go into that and 880 00:44:40,920 --> 00:44:43,040 Speaker 1: is this where we want to put our priorities. I 881 00:44:43,120 --> 00:44:46,840 Speaker 1: would note that NASA it's not funded at the levels 882 00:44:46,840 --> 00:44:48,799 Speaker 1: that most people think right when I like to play 883 00:44:48,840 --> 00:44:51,360 Speaker 1: this game like what percentage of the total US budget 884 00:44:51,560 --> 00:44:55,160 Speaker 1: is NASA getting and people are like twent and I'm 885 00:44:55,239 --> 00:45:00,840 Speaker 1: like that's great. I know, of like that would be amazing, 886 00:45:01,400 --> 00:45:04,520 Speaker 1: you know, but unfortunately, at its maximum, NASA has never 887 00:45:04,520 --> 00:45:06,600 Speaker 1: gotten more than one percent of the totally US budget. 888 00:45:06,600 --> 00:45:08,759 Speaker 1: It's much lower than that now, you know. So we 889 00:45:08,840 --> 00:45:13,440 Speaker 1: are doing all of this work with really very little funding, 890 00:45:13,520 --> 00:45:15,960 Speaker 1: which is amazing. We don't really need that much more 891 00:45:16,000 --> 00:45:19,600 Speaker 1: funding to make a sample return mission from Mars reality. 892 00:45:19,840 --> 00:45:21,680 Speaker 1: So that's that's what I would say. I would say, 893 00:45:21,680 --> 00:45:23,799 Speaker 1: you know, maybe it feels like it's a little bit 894 00:45:23,840 --> 00:45:26,320 Speaker 1: of extra money now, but the I think the rewards 895 00:45:26,320 --> 00:45:28,520 Speaker 1: would be incredible and it would absolutely be worth the 896 00:45:28,520 --> 00:45:30,840 Speaker 1: price tag. I agree with you. I think it's incredible 897 00:45:30,880 --> 00:45:33,279 Speaker 1: when we have the capability to do something and the 898 00:45:33,320 --> 00:45:35,839 Speaker 1: only thing that limits us is the money. It's like, 899 00:45:36,280 --> 00:45:38,600 Speaker 1: you're at the universe is like knowledge shop, and you 900 00:45:38,640 --> 00:45:41,600 Speaker 1: could just buy this information about the universe and the 901 00:45:41,640 --> 00:45:44,720 Speaker 1: money is there, but they're spending it on aircraft carriers. 902 00:45:44,840 --> 00:45:46,440 Speaker 1: So we need those two, We need them all, We 903 00:45:46,440 --> 00:45:48,799 Speaker 1: need all the things, but we could just you know, 904 00:45:49,160 --> 00:45:51,160 Speaker 1: I think people think of it as more expensive than 905 00:45:51,200 --> 00:45:54,080 Speaker 1: it really is. It really is a bargain. What we 906 00:45:54,120 --> 00:45:56,840 Speaker 1: can do really is. So let's say this mission happens. 907 00:45:57,239 --> 00:45:59,520 Speaker 1: There are several parts to it which seemed a little 908 00:45:59,600 --> 00:46:02,680 Speaker 1: you know, of wracking. Bit's being transferred from one to 909 00:46:02,719 --> 00:46:06,000 Speaker 1: the other. Say this happens. Which part is the most 910 00:46:06,120 --> 00:46:08,719 Speaker 1: nail biting for you? Which is the moment where you're like, 911 00:46:09,320 --> 00:46:11,640 Speaker 1: you know, holding your breath hoping that it works. I 912 00:46:11,640 --> 00:46:14,439 Speaker 1: think for me, the most anxiety ridden part of any 913 00:46:14,480 --> 00:46:17,600 Speaker 1: mission is launching and landing. Those are the hardest parts 914 00:46:17,640 --> 00:46:20,920 Speaker 1: that we do. It's really hard to launch something off 915 00:46:20,920 --> 00:46:24,360 Speaker 1: of another planet and get it onto another planet safely. 916 00:46:24,960 --> 00:46:28,080 Speaker 1: And so you know, we've we've done this now for 917 00:46:28,440 --> 00:46:31,520 Speaker 1: many missions successfully, right, but we can never guarantee that 918 00:46:31,600 --> 00:46:33,320 Speaker 1: it's going to always work out well. I think we 919 00:46:33,360 --> 00:46:35,799 Speaker 1: have a good track record, but we're gonna be trying 920 00:46:35,800 --> 00:46:39,000 Speaker 1: to do some very different things with sample return that 921 00:46:39,000 --> 00:46:41,279 Speaker 1: we've never tried before, and that is we've got to 922 00:46:41,560 --> 00:46:46,200 Speaker 1: first get our rover perseverance to Mars. So we're already launching, 923 00:46:46,280 --> 00:46:48,480 Speaker 1: We've already launched off of Earth and now we're en 924 00:46:48,600 --> 00:46:51,440 Speaker 1: route to Mars. We're gonna land on Mars. Then that 925 00:46:51,520 --> 00:46:54,719 Speaker 1: rover has to gather samples, and then we're gonna launch 926 00:46:54,760 --> 00:46:57,360 Speaker 1: another spacecraft that's gonna get into orbit around Mars, and 927 00:46:57,360 --> 00:46:59,400 Speaker 1: then that spacecraft is going to launch a lander with 928 00:46:59,440 --> 00:47:01,480 Speaker 1: a little fete strover, and that rover is gonna pick 929 00:47:01,520 --> 00:47:04,320 Speaker 1: up our samples and then get back to this lander 930 00:47:04,360 --> 00:47:07,080 Speaker 1: and then launch off of Mars. This is all by itself, 931 00:47:07,120 --> 00:47:10,000 Speaker 1: by the way, no help from us. Then it's gonna 932 00:47:10,000 --> 00:47:12,759 Speaker 1: rendezvous with that orbiting spacecraft, and then that spacecraft is 933 00:47:12,760 --> 00:47:17,479 Speaker 1: going to come back to Earth. That's very complicated. I 934 00:47:17,520 --> 00:47:20,440 Speaker 1: think we can absolutely do it. It's absolutely feasible, but 935 00:47:20,480 --> 00:47:22,920 Speaker 1: there's quite a bit of risk there, and especially because 936 00:47:22,960 --> 00:47:25,719 Speaker 1: we can't operate this in real time, these systems have 937 00:47:25,800 --> 00:47:29,439 Speaker 1: to be somewhat autonomous. So then imagine that it's here. 938 00:47:29,680 --> 00:47:32,239 Speaker 1: We have Mars samples there, sterile or pristine. They're in 939 00:47:32,239 --> 00:47:35,600 Speaker 1: the laboratory, and you're the first person to get cracked 940 00:47:35,600 --> 00:47:37,440 Speaker 1: at them. Right, what's the first thing you do to 941 00:47:37,520 --> 00:47:40,839 Speaker 1: those samples? What's the first question you want to answer? Oh, 942 00:47:40,880 --> 00:47:42,640 Speaker 1: my goodness, that is such a I mean, if I'm 943 00:47:42,680 --> 00:47:44,239 Speaker 1: the first person to see them, I don't know if 944 00:47:44,239 --> 00:47:45,560 Speaker 1: I could keep it from my friends. I have to 945 00:47:45,560 --> 00:47:47,560 Speaker 1: invite everybody over so we can all look at this together, 946 00:47:48,239 --> 00:47:51,000 Speaker 1: I think. I mean, the first step for bringing back 947 00:47:51,000 --> 00:47:53,200 Speaker 1: samples like this is you must triage them. So we 948 00:47:53,239 --> 00:47:55,680 Speaker 1: need to get a general sense what kind of rock 949 00:47:55,800 --> 00:47:59,000 Speaker 1: is this, what kind of minerals? You know, just basic characteristics, 950 00:47:59,640 --> 00:48:02,000 Speaker 1: because is that will then tell you what the next 951 00:48:02,040 --> 00:48:04,560 Speaker 1: question should be. You know, if you have a rock 952 00:48:04,719 --> 00:48:08,640 Speaker 1: that appears to be igneous, so from a volcano. The 953 00:48:08,680 --> 00:48:11,440 Speaker 1: next questions are going to be, you know, more about 954 00:48:11,880 --> 00:48:14,680 Speaker 1: how did vulcanism evolve in this place, you know, what 955 00:48:14,880 --> 00:48:18,560 Speaker 1: kind of volcano reduced this material, and then what happened 956 00:48:18,560 --> 00:48:21,640 Speaker 1: to it next. If you get a sedimentary sample, totally 957 00:48:21,680 --> 00:48:24,600 Speaker 1: different questions. You're like, Okay, so now this is sedimentary. 958 00:48:24,640 --> 00:48:27,719 Speaker 1: Was it emplaced in water? What kind of water? You know, 959 00:48:27,760 --> 00:48:30,319 Speaker 1: what's the nature of the properties of that fluid, and 960 00:48:30,360 --> 00:48:33,560 Speaker 1: then what kind of other minerals were precipitating there, and 961 00:48:33,600 --> 00:48:36,640 Speaker 1: what does that tell us about the habitability of that 962 00:48:36,800 --> 00:48:40,440 Speaker 1: environment and what kind of things could actually utilize you know, 963 00:48:40,480 --> 00:48:42,399 Speaker 1: what are the energy sources that might have been there. 964 00:48:42,680 --> 00:48:45,480 Speaker 1: So so I think like, depending on the first canister 965 00:48:45,640 --> 00:48:48,360 Speaker 1: that I open, you know, you go in a different direction. 966 00:48:48,880 --> 00:48:53,319 Speaker 1: So I'm hoping that we get some sedimentary materials that 967 00:48:53,360 --> 00:48:56,200 Speaker 1: are high in manganese, and we'll know that before they 968 00:48:56,239 --> 00:48:59,560 Speaker 1: come back from ours because we will select these very carefully, 969 00:48:59,600 --> 00:49:02,000 Speaker 1: So that would probably be something that will already know. 970 00:49:02,120 --> 00:49:05,200 Speaker 1: So I would pick, you know, my favorite canister to 971 00:49:05,239 --> 00:49:07,680 Speaker 1: open first so that I could follow my favorite questions. 972 00:49:08,080 --> 00:49:10,759 Speaker 1: And for me, I'm really interested in understanding, you know, 973 00:49:10,840 --> 00:49:15,239 Speaker 1: are there bio signatures that are preserved in sedimentary materials 974 00:49:15,239 --> 00:49:19,399 Speaker 1: on Mars. So these are chemical or mineralogical or even 975 00:49:19,400 --> 00:49:24,399 Speaker 1: morphological features that are left by life that can tell 976 00:49:24,440 --> 00:49:26,960 Speaker 1: us something about what it was doing. Um, and then 977 00:49:27,000 --> 00:49:28,719 Speaker 1: it can also, depending on the age of the rock, 978 00:49:28,880 --> 00:49:31,120 Speaker 1: tell us when it was doing that. So those are 979 00:49:31,120 --> 00:49:33,800 Speaker 1: the questions that I don't want to answer first. All right, wonderful. 980 00:49:33,840 --> 00:49:36,160 Speaker 1: Well I can hear your enthusiasm and it makes me 981 00:49:36,239 --> 00:49:42,640 Speaker 1: excited to get these samples back here. So thanks again 982 00:49:42,680 --> 00:49:45,160 Speaker 1: for coming out of program and for telling us about it. Yeah, 983 00:49:45,200 --> 00:49:47,680 Speaker 1: thanks for having me. It's been great chatting. All right, 984 00:49:48,000 --> 00:49:52,240 Speaker 1: pretty awesome. She's amazing. It sounds like it's totally possible, 985 00:49:52,320 --> 00:49:54,799 Speaker 1: Like this might work, Daniel. It's basically a question of 986 00:49:54,880 --> 00:49:57,600 Speaker 1: politics and money and then you know a little bit 987 00:49:57,600 --> 00:50:00,359 Speaker 1: of luck, like if we actually commit to doing thing 988 00:50:00,640 --> 00:50:02,839 Speaker 1: and to sending this thing over there, we have a 989 00:50:02,840 --> 00:50:06,360 Speaker 1: reasonable chance of it working. Really, you know, something of 990 00:50:06,520 --> 00:50:11,920 Speaker 1: missions to Mars fail. But that's a reasonable chance. Is 991 00:50:11,920 --> 00:50:13,960 Speaker 1: that our hit rate, Yeah, that's our hit rate, and 992 00:50:14,000 --> 00:50:15,399 Speaker 1: I think we have the best hit rate of any 993 00:50:15,400 --> 00:50:18,560 Speaker 1: country on Earth. But it's still it's tricky, it's far away. 994 00:50:18,600 --> 00:50:21,440 Speaker 1: These things are complicated. But remember what NASA has pulled 995 00:50:21,440 --> 00:50:24,399 Speaker 1: off like they have done amazing things like the sky 996 00:50:24,600 --> 00:50:27,719 Speaker 1: crane landing on Mars and all sorts of stuff. So 997 00:50:27,760 --> 00:50:30,640 Speaker 1: this some pretty awesome engineers over there. I trust them. 998 00:50:30,680 --> 00:50:33,640 Speaker 1: I think they deserve a couple of billion. Yeah, yeah, 999 00:50:33,680 --> 00:50:36,760 Speaker 1: you're saying that. The biggest challenges just keeping this project funded, 1000 00:50:36,800 --> 00:50:38,960 Speaker 1: because you know it takes years and years. It's like 1001 00:50:39,000 --> 00:50:42,200 Speaker 1: a twenty year project, fifteen year project. Yeah. If the 1002 00:50:42,239 --> 00:50:45,799 Speaker 1: samples do return, they'll be back here in twenty one 1003 00:50:46,719 --> 00:50:49,200 Speaker 1: and so it just needs constant funding. And you know 1004 00:50:49,239 --> 00:50:52,120 Speaker 1: how it is these days with politics. New administration comes in, 1005 00:50:52,640 --> 00:50:54,880 Speaker 1: first thing they love to do is cancel the projects 1006 00:50:54,880 --> 00:50:58,160 Speaker 1: from the previous administration, and so it has to be 1007 00:50:58,400 --> 00:51:04,359 Speaker 1: consistently supported by multiple branches of government in order to survive. Well, sure, yeah, 1008 00:51:04,440 --> 00:51:06,919 Speaker 1: let's give him all the billions. I mean not all 1009 00:51:06,920 --> 00:51:09,440 Speaker 1: of the billions, but a few of the billions. I 1010 00:51:09,600 --> 00:51:12,080 Speaker 1: think of the things we could learn. I'm always frustrated 1011 00:51:12,080 --> 00:51:15,279 Speaker 1: when there are opportunities to learn something important and deep 1012 00:51:15,320 --> 00:51:18,480 Speaker 1: about the universe and the only barrier is money, money 1013 00:51:18,520 --> 00:51:21,600 Speaker 1: that we have. I would totally go into the Universe 1014 00:51:21,719 --> 00:51:24,440 Speaker 1: knowledge Shop and spend lots of billions of dollars to 1015 00:51:24,520 --> 00:51:26,759 Speaker 1: learn things about the universe. You would totally press that 1016 00:51:26,880 --> 00:51:31,520 Speaker 1: red by now, but Mars rock by now. Sample of 1017 00:51:31,520 --> 00:51:34,759 Speaker 1: gas from Jupiter by now. Secrets of the universe. Click 1018 00:51:34,760 --> 00:51:41,600 Speaker 1: click click deliver tomorrow please next day delivery please. All right? Well, 1019 00:51:42,040 --> 00:51:45,680 Speaker 1: Dr Lanson was definitely excited. We're excited, and good luck 1020 00:51:45,719 --> 00:51:47,759 Speaker 1: to the Mars scientists who are working on this and 1021 00:51:47,800 --> 00:51:50,840 Speaker 1: tune in one. Well we'll break down for you the 1022 00:51:50,880 --> 00:51:55,720 Speaker 1: incredible discoveries made by Mars. Sample return. That's right today 1023 00:51:55,760 --> 00:51:59,880 Speaker 1: on episode three thousand, Daniel and Horror Explained Auniverse. Remember 1024 00:51:59,880 --> 00:52:02,279 Speaker 1: that time we interviewed one of the scientists. No, it 1025 00:52:02,320 --> 00:52:04,600 Speaker 1: will be two robots. Two robots will have taken over 1026 00:52:04,600 --> 00:52:09,120 Speaker 1: the podcast by then, and together they'll transform into an 1027 00:52:09,120 --> 00:52:14,920 Speaker 1: awesome podcast actually making good jokes that end up on 1028 00:52:14,960 --> 00:52:17,520 Speaker 1: a trump All right, well, thanks for joining us.
