1 00:00:03,120 --> 00:00:06,000 Speaker 1: Welcome to stuff to blow your mind from how stuff 2 00:00:06,000 --> 00:00:14,080 Speaker 1: weren't dot com? Hey, welcome to stuff to blow your mind. 3 00:00:14,120 --> 00:00:17,840 Speaker 1: My name is Robert Lamb and I'm Joe McCormick. So Robert, Yes, 4 00:00:18,680 --> 00:00:22,880 Speaker 1: I wanna put you in a strange scenario. I want 5 00:00:22,920 --> 00:00:28,400 Speaker 1: you to imagine yourself an astronaut in a near future dystopia, 6 00:00:28,520 --> 00:00:32,280 Speaker 1: in fact, a truly dystopian scenario. From my perspective, to 7 00:00:32,320 --> 00:00:34,920 Speaker 1: do this is an exer side I try to employ 8 00:00:35,040 --> 00:00:36,959 Speaker 1: you know every day. Okay, Now, you might be going 9 00:00:37,040 --> 00:00:40,560 Speaker 1: to a kind of Orwellian place, like the totalitarian Hell 10 00:00:40,760 --> 00:00:43,640 Speaker 1: don't go there. Or you might be going to like 11 00:00:43,720 --> 00:00:46,479 Speaker 1: the oldest Huxley place where we're all just medicated and 12 00:00:46,520 --> 00:00:51,800 Speaker 1: placated and have an empty, soulless bliss. Not there. I 13 00:00:51,840 --> 00:00:56,360 Speaker 1: want you to put yourself in the actuarial capitalist bureaucracy 14 00:00:56,440 --> 00:01:01,760 Speaker 1: of the private insurance market. Okay, okay, so we land 15 00:01:01,800 --> 00:01:03,800 Speaker 1: in a place that's maybe a little more comfortable, but 16 00:01:03,840 --> 00:01:08,200 Speaker 1: a little more mundane. So specifically, what you're trying to 17 00:01:08,240 --> 00:01:11,440 Speaker 1: do is purchase a suite of insurance policies that will 18 00:01:11,480 --> 00:01:15,600 Speaker 1: protect you and your family if you suffer death, disability, 19 00:01:15,680 --> 00:01:18,560 Speaker 1: or a serious medical condition in your line of work. 20 00:01:19,520 --> 00:01:22,280 Speaker 1: So during a brief interview, there's a policy agent who 21 00:01:22,360 --> 00:01:25,199 Speaker 1: has to ask you if you questions to determine whether 22 00:01:25,240 --> 00:01:27,120 Speaker 1: they can sell you a policy and what your rate 23 00:01:27,200 --> 00:01:29,039 Speaker 1: is going to be, so you get the standard ones. 24 00:01:29,080 --> 00:01:33,720 Speaker 1: Are you a smoker, heavy drinker, ivy drug user? Wait? 25 00:01:33,959 --> 00:01:38,400 Speaker 1: What this is the future? Right? Yes? Okay? Uh duelist 26 00:01:38,480 --> 00:01:44,640 Speaker 1: and or gun slinger? Um, this is the future? Yeah, um, 27 00:01:44,680 --> 00:01:49,960 Speaker 1: I'll say sometimes how about drag race junkie night of 28 00:01:50,000 --> 00:01:53,520 Speaker 1: the Sacred art of the motor joust? Um? Do you 29 00:01:53,520 --> 00:01:57,840 Speaker 1: work with high voltage nitroglycerin or flying guillotines? Not currently? 30 00:01:58,160 --> 00:02:04,559 Speaker 1: And does your church congregation practice snake handling? Not bio snakes? 31 00:02:04,600 --> 00:02:07,760 Speaker 1: So we're good, right, you only get those uh those 32 00:02:07,800 --> 00:02:10,240 Speaker 1: safe synthetic snakes. Yeah, yeah, I mean so we get 33 00:02:10,240 --> 00:02:12,240 Speaker 1: you know, the spirit of the practice is still true. 34 00:02:12,360 --> 00:02:15,519 Speaker 1: It's not the Middle Ages. Come on the future. Okay. 35 00:02:15,520 --> 00:02:17,840 Speaker 1: So we're all the way through the interview except for 36 00:02:17,840 --> 00:02:20,399 Speaker 1: one final question. Are you now or have you ever 37 00:02:20,480 --> 00:02:23,520 Speaker 1: been on the waiting list for a space colonization project? 38 00:02:26,320 --> 00:02:28,680 Speaker 1: And there you got me? Yeah, I got you. Sorry, 39 00:02:28,760 --> 00:02:31,799 Speaker 1: that's the kicker, because Robert, I know that you are 40 00:02:31,840 --> 00:02:35,680 Speaker 1: in fact, currently an in astronaut training to become one 41 00:02:35,720 --> 00:02:38,399 Speaker 1: of the members of the first wave of semi permanent 42 00:02:38,639 --> 00:02:42,560 Speaker 1: Mars colonists. Uh. And depending on circumstances, you might be 43 00:02:42,600 --> 00:02:45,360 Speaker 1: spending the next six to twelve years and maybe the 44 00:02:45,480 --> 00:02:49,160 Speaker 1: rest of your natural life in a habitat on the 45 00:02:49,200 --> 00:02:53,799 Speaker 1: surface of a red, red waste land. And unfortunately you're 46 00:02:53,840 --> 00:02:56,080 Speaker 1: well aware of this, and well aware of the fact 47 00:02:56,160 --> 00:02:59,080 Speaker 1: that if you answer yes to this question, your monthly 48 00:02:59,080 --> 00:03:01,280 Speaker 1: payments are going to be so high as to defeat 49 00:03:01,320 --> 00:03:04,200 Speaker 1: the entire purpose of the insurance policy, right, because this 50 00:03:04,280 --> 00:03:07,239 Speaker 1: is a risky venture. This is this is even beyond 51 00:03:07,400 --> 00:03:10,519 Speaker 1: drag racing and motor jousting and what have you. This 52 00:03:10,600 --> 00:03:13,120 Speaker 1: is uh, this is this is a risky lifestyle to 53 00:03:13,160 --> 00:03:15,520 Speaker 1: take on. How true that is? Now, you could do 54 00:03:15,600 --> 00:03:17,840 Speaker 1: what Neil Armstrong and the rest of the crew of 55 00:03:17,880 --> 00:03:20,600 Speaker 1: Apollo eleven did. Did Did you ever hear about this story? Now? 56 00:03:21,080 --> 00:03:24,320 Speaker 1: The whole insurance policies for astronaut is is an area 57 00:03:24,440 --> 00:03:27,320 Speaker 1: I've I've not explored well. When the crew of the 58 00:03:27,360 --> 00:03:29,320 Speaker 1: Apollo eleven mission, who were going to be the first 59 00:03:29,360 --> 00:03:32,079 Speaker 1: people to land on the Moon, realized that life insurance 60 00:03:32,120 --> 00:03:35,880 Speaker 1: policies would be prohibitively expensive for them. They came up 61 00:03:35,880 --> 00:03:39,080 Speaker 1: with an interesting idea to to make a policy of 62 00:03:39,120 --> 00:03:41,360 Speaker 1: their own. So, during the month when they were in 63 00:03:41,440 --> 00:03:45,119 Speaker 1: quarantine before launch, and this is true, they signed hundreds 64 00:03:45,160 --> 00:03:48,840 Speaker 1: of autographed covers they were called which were these envelopes 65 00:03:48,960 --> 00:03:53,600 Speaker 1: postmarked with historically significant dates on them? Uh, And they were. 66 00:03:53,640 --> 00:03:56,480 Speaker 1: They were autographing these covers, and then they would deliver 67 00:03:56,600 --> 00:03:58,840 Speaker 1: them all to their families. This way, they knew that 68 00:03:58,880 --> 00:04:01,280 Speaker 1: if they didn't survive of the mission, the sale of 69 00:04:01,360 --> 00:04:04,680 Speaker 1: autographed memorabilia would at least be enough to keep their 70 00:04:04,720 --> 00:04:07,880 Speaker 1: families afloat. So since I'm probably not going to get 71 00:04:07,920 --> 00:04:12,280 Speaker 1: this insurance policy because of my my my aspirations to 72 00:04:12,280 --> 00:04:15,520 Speaker 1: to become a Mars colonist, I can at least set 73 00:04:15,600 --> 00:04:18,479 Speaker 1: up the possibility that my family can make money off 74 00:04:18,520 --> 00:04:22,320 Speaker 1: the fact that I am Slash was the first man 75 00:04:22,400 --> 00:04:25,680 Speaker 1: to die on Mars. Yeah, okay, I could see that. Yeah, 76 00:04:25,680 --> 00:04:28,000 Speaker 1: I mean that the motion pictures that would be made 77 00:04:28,000 --> 00:04:30,880 Speaker 1: about me, the rights to your life. Who's gonna play 78 00:04:30,920 --> 00:04:33,960 Speaker 1: you dying on Mars? I I hope everybody. They would 79 00:04:34,000 --> 00:04:36,640 Speaker 1: be like a Bob Dylan kind of thing, where different 80 00:04:36,720 --> 00:04:39,800 Speaker 1: actors and actress would would play me at different stages 81 00:04:39,839 --> 00:04:44,080 Speaker 1: of my demise. Kate Blanchets you gasping on the red Rock. 82 00:04:44,400 --> 00:04:47,680 Speaker 1: I think that's perfect. That would be pretty cool. But anyway, 83 00:04:48,000 --> 00:04:50,599 Speaker 1: put yourself back in the scenario. So the insurance agent 84 00:04:51,880 --> 00:04:55,280 Speaker 1: that that question might actually cause you to have some 85 00:04:55,320 --> 00:04:59,920 Speaker 1: second thoughts about your plans to go to Mars because 86 00:05:00,040 --> 00:05:02,040 Speaker 1: of what your body is going to be up against. 87 00:05:02,040 --> 00:05:04,839 Speaker 1: Now you know a few things, but you might not 88 00:05:04,960 --> 00:05:09,679 Speaker 1: realize the entire spate of potential challenges to your health 89 00:05:09,680 --> 00:05:13,360 Speaker 1: and well being while living on Mars, well while bound 90 00:05:13,400 --> 00:05:16,240 Speaker 1: for Mars, and once you get there, especially since you 91 00:05:16,279 --> 00:05:18,520 Speaker 1: couldn't wait out the years of preparation it was going 92 00:05:18,560 --> 00:05:21,279 Speaker 1: to take to be part of the joint NASA Jackson Yes, 93 00:05:21,360 --> 00:05:23,919 Speaker 1: a mission, and instead you have signed up with a 94 00:05:24,000 --> 00:05:28,719 Speaker 1: kind of sketchy sounding nonprofit based Mars colonization outfit because 95 00:05:28,760 --> 00:05:31,719 Speaker 1: they promised lift off within eighteen months and you're in 96 00:05:31,720 --> 00:05:35,200 Speaker 1: a hurry. Though from what you've seen so far, they 97 00:05:35,279 --> 00:05:38,240 Speaker 1: might be cutting some corners. Uh. Yeah, I was very 98 00:05:38,279 --> 00:05:41,400 Speaker 1: skeptical of the the wooden spaceship approach that they were 99 00:05:41,760 --> 00:05:44,200 Speaker 1: they were looking to employ. Did you ever read that? 100 00:05:44,240 --> 00:05:47,120 Speaker 1: What was that there? Was a proposition that that the 101 00:05:47,200 --> 00:05:49,719 Speaker 1: movie Alien three was originally going to be about a 102 00:05:49,720 --> 00:05:52,400 Speaker 1: wooden planet. Oh yeah, I go, yeah, wooden space station 103 00:05:52,520 --> 00:05:56,640 Speaker 1: man by monks. That idea. Pretty wish they'd made that. Anyway, 104 00:05:56,680 --> 00:05:59,559 Speaker 1: back to the story, So this is a good jumping 105 00:05:59,600 --> 00:06:02,520 Speaker 1: off point to talk about the real thrust of today's episode, 106 00:06:02,520 --> 00:06:05,599 Speaker 1: which is the question, what are all of the health 107 00:06:05,839 --> 00:06:08,880 Speaker 1: challenges that our bodies might face over the course of 108 00:06:08,920 --> 00:06:13,240 Speaker 1: a long term Mars colonization effort, both traveling to Mars 109 00:06:13,440 --> 00:06:16,200 Speaker 1: and living there for years at a time or maybe 110 00:06:16,240 --> 00:06:19,280 Speaker 1: for a whole lifetime, And are there anyways we know 111 00:06:19,320 --> 00:06:22,320 Speaker 1: of to overcome these challenges? Yeah, it's a it's a 112 00:06:22,320 --> 00:06:25,559 Speaker 1: big question one that uh that NASA and other space 113 00:06:25,600 --> 00:06:30,200 Speaker 1: exploration authorities continue to look into, because that's kind of 114 00:06:30,240 --> 00:06:33,440 Speaker 1: the next big phase, right, that's the dream that's our 115 00:06:33,520 --> 00:06:37,560 Speaker 1: generation's moon, the idea of actually making it to the 116 00:06:37,600 --> 00:06:41,120 Speaker 1: red planet, of leaving this world that we've evolved to 117 00:06:41,400 --> 00:06:44,559 Speaker 1: thrive on and to thrive within a very slim portion 118 00:06:44,600 --> 00:06:47,400 Speaker 1: of the atmosphere and also only in certain regions of 119 00:06:47,400 --> 00:06:52,160 Speaker 1: the planet, to leave this world, travel through the unforgiving 120 00:06:52,240 --> 00:06:57,279 Speaker 1: void of space to a rather lifeless world and somehow 121 00:06:57,320 --> 00:06:59,480 Speaker 1: make a go of it. Yeah, well, we certainly don't 122 00:06:59,520 --> 00:07:03,640 Speaker 1: want to discourage Mars exploration with this podcast, but I 123 00:07:03,680 --> 00:07:08,640 Speaker 1: think it's just helpful while encouraging the exploratory and scientific 124 00:07:08,720 --> 00:07:13,120 Speaker 1: spirit to also realize what a truly horrible place Mars is. 125 00:07:14,200 --> 00:07:15,960 Speaker 1: So I think we should start with some of the 126 00:07:16,000 --> 00:07:19,200 Speaker 1: more obvious and more often talked about issues such as 127 00:07:19,480 --> 00:07:25,120 Speaker 1: radiation and reduced gravity micro gravity or zero gravity as 128 00:07:25,120 --> 00:07:27,320 Speaker 1: the case may be, and and then move on to 129 00:07:27,440 --> 00:07:31,520 Speaker 1: some of the more obscure concerns. So, the biggest health concern, 130 00:07:31,840 --> 00:07:36,000 Speaker 1: quite obviously for Mars travelers is going to be radiation exposure. Indeed, 131 00:07:36,040 --> 00:07:38,560 Speaker 1: we live in a kind of privileged a situation here 132 00:07:38,560 --> 00:07:41,560 Speaker 1: on Earth because we're we're largely shielded from some of 133 00:07:41,600 --> 00:07:45,160 Speaker 1: the the harsher radiation that can reach us in the 134 00:07:45,200 --> 00:07:47,920 Speaker 1: form of cosmic radiation and in a lot of the 135 00:07:47,920 --> 00:07:51,360 Speaker 1: solar radiation. Yeah, that's certainly true, And we actually would 136 00:07:51,400 --> 00:07:54,600 Speaker 1: have to deal with radiation in two different scenarios that 137 00:07:54,760 --> 00:07:57,640 Speaker 1: both apply to the Mars colonists. So there's gonna be 138 00:07:57,640 --> 00:08:01,000 Speaker 1: the radiation on the way to Mars and the radiation 139 00:08:01,040 --> 00:08:04,080 Speaker 1: once you get there. Because it's a sad fact that 140 00:08:04,200 --> 00:08:07,680 Speaker 1: Mars is not shielded the way Earth is, so both 141 00:08:07,720 --> 00:08:11,880 Speaker 1: cosmic and solar radiation immediately become a problem once you 142 00:08:11,960 --> 00:08:14,960 Speaker 1: leave the neighborhood of Earth. Even on Earth's surface, we're 143 00:08:15,640 --> 00:08:19,000 Speaker 1: actually exposed to a steady ambient level of radiation from 144 00:08:19,000 --> 00:08:21,600 Speaker 1: the Sun and from the larger universe. That would be 145 00:08:21,600 --> 00:08:26,920 Speaker 1: solar radiation and cosmic radiation, respectively. But Earth's atmosphere and 146 00:08:27,120 --> 00:08:30,680 Speaker 1: magneto sphere, so that's the magnetic field generated by the 147 00:08:30,760 --> 00:08:35,280 Speaker 1: dynamo effect when the Earth's liquid metal outer core rotates 148 00:08:35,280 --> 00:08:38,480 Speaker 1: around the intercore, an effect that most planets, uh that 149 00:08:38,559 --> 00:08:42,800 Speaker 1: we know do not feature. Yeah. Uh, that protects us 150 00:08:42,840 --> 00:08:45,360 Speaker 1: from the danger. So most of the incoming radiation gets 151 00:08:45,440 --> 00:08:48,520 Speaker 1: deflected or absorbed and we don't really have to worry 152 00:08:48,559 --> 00:08:51,920 Speaker 1: about it. Even astronauts on the International Space Station, which 153 00:08:51,960 --> 00:08:55,160 Speaker 1: is on average two nine miles above the surface of Earth, 154 00:08:55,559 --> 00:08:58,600 Speaker 1: even though they're exposed to more radiation than we get 155 00:08:58,640 --> 00:09:01,880 Speaker 1: on the surface, there's still shielded by Earth's magnetosphere, which 156 00:09:01,880 --> 00:09:05,600 Speaker 1: extends thousands of miles out into space. Yeah. When you 157 00:09:05,679 --> 00:09:09,280 Speaker 1: take that into account, I mean it's it's hostile and unforgiving. 158 00:09:09,360 --> 00:09:12,880 Speaker 1: As as the orbital environment is, it makes it seem like, 159 00:09:13,200 --> 00:09:15,280 Speaker 1: you know, like a five year old camping in his 160 00:09:15,360 --> 00:09:20,800 Speaker 1: parents backyard compared to actually venturing beyond the magnetosphere into 161 00:09:20,960 --> 00:09:24,280 Speaker 1: this unprotected regional space. Well, it's the equivalent of like 162 00:09:24,440 --> 00:09:27,360 Speaker 1: wading into three feet of water as opposed to swimming 163 00:09:27,360 --> 00:09:31,240 Speaker 1: across the ocean. But yeah, so once you're traveling in 164 00:09:31,480 --> 00:09:33,439 Speaker 1: outer space on the way to Mars, you no longer 165 00:09:33,480 --> 00:09:36,480 Speaker 1: have these protective barriers. And even once you get to Mars, 166 00:09:36,840 --> 00:09:39,439 Speaker 1: as we said, things aren't gonna be much better because 167 00:09:39,480 --> 00:09:42,520 Speaker 1: Mars does not have a strong magnetosphere like Earth, and 168 00:09:42,559 --> 00:09:45,719 Speaker 1: its atmosphere is absolutely puny. It's puny and thin. It's 169 00:09:45,720 --> 00:09:48,840 Speaker 1: about one percent the thickness of Earth's atmosphere. So you're 170 00:09:48,880 --> 00:09:52,160 Speaker 1: just not going to get much protection from radiation on Mars. 171 00:09:53,200 --> 00:09:55,400 Speaker 1: And there are ways to get around this. So people 172 00:09:55,440 --> 00:09:58,000 Speaker 1: have been coming up with all kinds of habitat and 173 00:09:58,200 --> 00:10:02,040 Speaker 1: space ship designs that would try to shield astronauts from 174 00:10:02,040 --> 00:10:04,440 Speaker 1: the various types of radiation they would encounter. So some 175 00:10:04,520 --> 00:10:07,679 Speaker 1: ideas are how to how to make shielding around a 176 00:10:07,760 --> 00:10:11,240 Speaker 1: spaceship that would absorb cosmic rays and try to prevent 177 00:10:11,320 --> 00:10:15,319 Speaker 1: secondary radiation from shooting off and irradiating you. One interesting 178 00:10:15,360 --> 00:10:19,000 Speaker 1: idea of read about is surrounding the crew capsule with 179 00:10:19,320 --> 00:10:23,520 Speaker 1: organic materials and water, so all of the food and 180 00:10:23,720 --> 00:10:27,280 Speaker 1: human waste and water and things like that would go, 181 00:10:27,520 --> 00:10:31,920 Speaker 1: would sort of form a weird moist BioShield around you. 182 00:10:32,240 --> 00:10:34,360 Speaker 1: Oh wow, so in in a sense, you would be 183 00:10:34,760 --> 00:10:40,440 Speaker 1: sailing to Mars in a protective bubble of your own sewage. Yes, exactly. Yeah, 184 00:10:40,600 --> 00:10:45,720 Speaker 1: it's sewage to the future. It will save your life, hopefully, 185 00:10:45,760 --> 00:10:48,880 Speaker 1: But we need to do more research to determine exactly 186 00:10:48,920 --> 00:10:51,640 Speaker 1: what the risks are and if we can create a 187 00:10:51,679 --> 00:10:55,640 Speaker 1: system like this that's economically feasible and we'll keep astronauts safe. 188 00:10:55,640 --> 00:10:59,560 Speaker 1: Because another problem is, sure, you can build a radiation shield. 189 00:10:59,559 --> 00:11:01,120 Speaker 1: I mean, we've build stuff like that all the time. 190 00:11:01,120 --> 00:11:03,600 Speaker 1: We have nuclear power plants, people who work with radiation, 191 00:11:03,640 --> 00:11:06,920 Speaker 1: and they can do that with relative protection. But it's 192 00:11:07,000 --> 00:11:10,200 Speaker 1: expensive to ship stuff into space, and the more bulk 193 00:11:10,280 --> 00:11:13,960 Speaker 1: you're adding to your ship to shield yourself, the more 194 00:11:14,000 --> 00:11:16,960 Speaker 1: trouble you're making this mission. Yeah, and it's in a 195 00:11:17,000 --> 00:11:19,400 Speaker 1: continuing theme that we'll we'll keep coming back to here 196 00:11:19,480 --> 00:11:21,640 Speaker 1: is is so much of this work is still ongoing. 197 00:11:21,640 --> 00:11:24,240 Speaker 1: We're still trying to find the answers, still trying to 198 00:11:24,240 --> 00:11:27,120 Speaker 1: figure out the best methods and dealing with a limited 199 00:11:27,120 --> 00:11:32,079 Speaker 1: ability to experiment on them. UH in real life. Totally true, 200 00:11:32,240 --> 00:11:37,400 Speaker 1: And unfortunately, it's not even just the standard radiation risks 201 00:11:37,480 --> 00:11:39,840 Speaker 1: that we're going to be dealing with during the trip 202 00:11:39,880 --> 00:11:42,240 Speaker 1: to Mars. So a standard trip to Mars might take 203 00:11:42,280 --> 00:11:46,480 Speaker 1: somewhere around six months. This is an estimate you see 204 00:11:46,480 --> 00:11:49,719 Speaker 1: thrown out a lot, and during those six months, and 205 00:11:49,840 --> 00:11:52,320 Speaker 1: once you get get to Mars, it's not just the 206 00:11:52,400 --> 00:11:57,040 Speaker 1: increased risk of cancer and other standard dangers associated with radiation. 207 00:11:57,400 --> 00:12:00,360 Speaker 1: Astronauts bound for Mars might face even weird or and 208 00:12:00,440 --> 00:12:06,040 Speaker 1: more disturbing dangers, for example, brain damage. So there is 209 00:12:06,080 --> 00:12:09,319 Speaker 1: some evidence that the kinds of cosmic rays that will 210 00:12:09,360 --> 00:12:12,839 Speaker 1: be cutting through your body on a regular basis while 211 00:12:12,920 --> 00:12:16,400 Speaker 1: you're on the way to Mars can produce brain damage, 212 00:12:16,480 --> 00:12:22,120 Speaker 1: leading to symptoms somewhat analogous to neurodegenerative diseases like Alzheimer's UH, 213 00:12:22,160 --> 00:12:24,960 Speaker 1: and I've read a few articles about this. So medical 214 00:12:25,040 --> 00:12:28,959 Speaker 1: doctors have noted that some patients who receive radiation to 215 00:12:29,040 --> 00:12:32,880 Speaker 1: the head in the course of treating brain cancer display 216 00:12:32,920 --> 00:12:37,320 Speaker 1: side effects like increased confusion and other cognitive impairments, and 217 00:12:37,400 --> 00:12:41,400 Speaker 1: cosmic rays might do pretty much the same thing to us. 218 00:12:41,440 --> 00:12:46,120 Speaker 1: So in recent experiments, researchers have subjected mice to simulated 219 00:12:46,280 --> 00:12:51,000 Speaker 1: cosmic rays, and six weeks after acute exposure to this radiation, 220 00:12:51,360 --> 00:12:55,800 Speaker 1: the mice exhibited decreased cognitive performance as well as physiological 221 00:12:55,880 --> 00:12:58,600 Speaker 1: changes to brain tissue. And I just want to read this, 222 00:12:59,240 --> 00:13:01,920 Speaker 1: uh quote from the abstract of the study. It was 223 00:13:02,120 --> 00:13:07,079 Speaker 1: reductions in dendritic complexity and spine density along the medial 224 00:13:07,120 --> 00:13:13,079 Speaker 1: prefrontal cortical neurons known to mediate neurotransmissions specifically interrogated by 225 00:13:13,080 --> 00:13:17,240 Speaker 1: our behavioral tasks. So so your ability to behave with 226 00:13:17,320 --> 00:13:22,280 Speaker 1: intelligence could be impaired by the time you arrive at Mars. 227 00:13:24,000 --> 00:13:29,120 Speaker 1: Showing up at Mars brain damage is not a good idea. Yeah, yeah, right, 228 00:13:29,160 --> 00:13:32,160 Speaker 1: when a lot of the really heavy work is about 229 00:13:32,160 --> 00:13:34,480 Speaker 1: to begin. Yeah. And so a couple of notes, these 230 00:13:34,480 --> 00:13:36,920 Speaker 1: are mice brains, not human brains, and we know there's 231 00:13:36,920 --> 00:13:39,720 Speaker 1: some difference there. Also, we we should be able to 232 00:13:39,760 --> 00:13:42,080 Speaker 1: protect against this, like I was saying earlier, if we 233 00:13:42,160 --> 00:13:45,120 Speaker 1: prepare and invest enough, if we do the research, figure 234 00:13:45,120 --> 00:13:47,880 Speaker 1: out what the vulnerabilities are, and build the right kind 235 00:13:47,880 --> 00:13:51,000 Speaker 1: of shielding. But again it's an economics problem. Can we 236 00:13:51,040 --> 00:13:54,600 Speaker 1: invest enough resources to make sure people are safe from 237 00:13:54,600 --> 00:13:59,000 Speaker 1: these effects? If you're going on the nonprofit cutting corners 238 00:13:59,320 --> 00:14:03,199 Speaker 1: get you there fast missions, that might not be the case. Yeah, 239 00:14:03,240 --> 00:14:05,320 Speaker 1: I don't know if the balsa wood shielding is going 240 00:14:05,400 --> 00:14:07,600 Speaker 1: to work and the outfit that I've been I've been 241 00:14:07,640 --> 00:14:10,559 Speaker 1: reading the brochure about. But of course it's not just 242 00:14:10,679 --> 00:14:13,640 Speaker 1: the radiation that will threaten our bodies on the trip 243 00:14:13,679 --> 00:14:17,559 Speaker 1: to Mars. What about the effects of micro gravity. Yeah, 244 00:14:17,600 --> 00:14:19,240 Speaker 1: this is a big one. And again I'm sure this 245 00:14:19,320 --> 00:14:22,720 Speaker 1: is one that that everyone is familiar with on some level. Uh, 246 00:14:22,800 --> 00:14:25,200 Speaker 1: you know, it often shows well, I was about to 247 00:14:25,240 --> 00:14:27,320 Speaker 1: say it often shows up in science fiction, but more 248 00:14:27,680 --> 00:14:30,560 Speaker 1: more often it's ignored in science fiction than the whole 249 00:14:30,560 --> 00:14:33,240 Speaker 1: issue of of of gravity and the lack of gravity 250 00:14:33,280 --> 00:14:35,360 Speaker 1: and space flight. Generally, you just throtle in some sort 251 00:14:35,400 --> 00:14:39,080 Speaker 1: of magical artificial gravity scenario and you don't worry about it. 252 00:14:39,160 --> 00:14:43,120 Speaker 1: I always respect the science fiction universes that have some 253 00:14:43,200 --> 00:14:45,920 Speaker 1: kind of rotating device on the ship to generate the 254 00:14:46,280 --> 00:14:49,520 Speaker 1: force of gravity. Yeah, where it's not just the millennium 255 00:14:49,520 --> 00:14:52,280 Speaker 1: falcon and you can walk around wherever. Yeah, because the 256 00:14:52,720 --> 00:14:56,400 Speaker 1: bottom line, of course, is that we evolved on a 257 00:14:56,920 --> 00:15:00,080 Speaker 1: world with a certain amount of gravitational pull and we're 258 00:15:00,120 --> 00:15:03,240 Speaker 1: completely adapted to it. Yeah, everything about our form and 259 00:15:03,240 --> 00:15:06,480 Speaker 1: gravity dictates the form of our muscle groups. Uh. And 260 00:15:06,520 --> 00:15:10,360 Speaker 1: gravity alone forces a certain level of exercise on you 261 00:15:10,440 --> 00:15:12,400 Speaker 1: at all times. So even if you're just you know, 262 00:15:12,480 --> 00:15:16,920 Speaker 1: standing in your apartment otherwise doing nothing, your body is 263 00:15:16,920 --> 00:15:20,600 Speaker 1: still working with gravity. And on a microscopic level, our 264 00:15:20,600 --> 00:15:25,280 Speaker 1: skeleton constantly alters its structure to bear the gravitational forces 265 00:15:25,320 --> 00:15:28,400 Speaker 1: of our planet. Even our organs work with it. With 266 00:15:28,640 --> 00:15:31,320 Speaker 1: with Earth gravity, I mean our heart beats against gravity 267 00:15:31,320 --> 00:15:34,600 Speaker 1: when it pushes blood um up to our brains. So 268 00:15:34,680 --> 00:15:36,560 Speaker 1: I mean we are we are just steeped in it. 269 00:15:36,640 --> 00:15:38,600 Speaker 1: We often take it for granted. I mean we we 270 00:15:38,600 --> 00:15:41,520 Speaker 1: almost always take it for granted. But we are creatures 271 00:15:41,560 --> 00:15:45,960 Speaker 1: that have evolved to live with our gravity, with Earth gravity. Yeah, 272 00:15:46,000 --> 00:15:48,760 Speaker 1: you don't think about it, but your body is constantly 273 00:15:48,800 --> 00:15:53,200 Speaker 1: having to compensate for gravity. I mean, the gravity wants 274 00:15:53,280 --> 00:15:55,600 Speaker 1: to pull you towards the floor. The gravity wants to 275 00:15:55,640 --> 00:15:58,400 Speaker 1: pull all your blood into your feet. So, like you said, 276 00:15:58,840 --> 00:16:02,040 Speaker 1: your circulatory says them, Like you mentioned has to pump 277 00:16:02,200 --> 00:16:04,640 Speaker 1: more blood pressure into the top of your body just 278 00:16:04,720 --> 00:16:07,680 Speaker 1: to make sure you get an even circulation, all because 279 00:16:07,680 --> 00:16:11,520 Speaker 1: of gravity. Indeed, so when we when we send astronauts 280 00:16:11,560 --> 00:16:15,360 Speaker 1: into space, when they go into orbit, um, they experience 281 00:16:15,400 --> 00:16:19,680 Speaker 1: a certain amount of muscle and skeleptle system deterioration. It's 282 00:16:19,720 --> 00:16:23,520 Speaker 1: called getting soft. Yeah, and literally that's that's what happens. 283 00:16:24,080 --> 00:16:28,600 Speaker 1: The muscles, especially the underutilized leg muscles, become flabby, lose 284 00:16:28,640 --> 00:16:34,040 Speaker 1: tone and mass, Muscular atrophy occurs. Bone becomes weaker because 285 00:16:34,160 --> 00:16:37,120 Speaker 1: of the loss of the minerals calcium, potassium, and sodium 286 00:16:37,680 --> 00:16:41,520 Speaker 1: um and the bone degeneration can reduce bone in the 287 00:16:41,560 --> 00:16:46,360 Speaker 1: lower limbs by so it's essentially a form of osteoporosis 288 00:16:46,400 --> 00:16:50,400 Speaker 1: known as space flight osteopenia. Yeah, and astronauts have to 289 00:16:50,400 --> 00:16:53,480 Speaker 1: do tons of exercise just to prevent this from being 290 00:16:53,560 --> 00:16:56,280 Speaker 1: worse than it is. Yeah, they're a number that there's 291 00:16:56,280 --> 00:17:00,800 Speaker 1: a lot of exercise. Um. Also, astronauts will generally take 292 00:17:01,520 --> 00:17:04,960 Speaker 1: various vitamins and even some pharmaceuticals. Particularly will take calcium 293 00:17:04,960 --> 00:17:08,480 Speaker 1: and vitamin d H. NASA often you know, tends to 294 00:17:08,520 --> 00:17:11,160 Speaker 1: have their their astronauts take clay to help to supposedly 295 00:17:11,200 --> 00:17:14,760 Speaker 1: help with calcium retention and then also uh, and it's 296 00:17:14,760 --> 00:17:17,760 Speaker 1: thought that osteoporosis drugs can be helpful in mitigating this 297 00:17:17,880 --> 00:17:22,119 Speaker 1: as well. Um, it's interesting the calcium is especially a problem. 298 00:17:22,160 --> 00:17:25,159 Speaker 1: The calcium loss in the bones of our body is 299 00:17:25,200 --> 00:17:27,639 Speaker 1: calcium is stored in the skeleton, and when we lose 300 00:17:27,680 --> 00:17:31,280 Speaker 1: it in low gravity, it enters the bloodstream, where an 301 00:17:31,280 --> 00:17:34,520 Speaker 1: excess of calcium can cause a host of unpleasantries. You know, 302 00:17:34,600 --> 00:17:36,560 Speaker 1: that could be as mild as just you know, diarrhea. 303 00:17:36,640 --> 00:17:40,320 Speaker 1: But you don't need another reason to have diarrhea in space. Yeah, well, 304 00:17:40,359 --> 00:17:43,560 Speaker 1: I mean you don't need you don't need a reason 305 00:17:43,600 --> 00:17:46,359 Speaker 1: to have any condition in space. That plays on another 306 00:17:46,400 --> 00:17:50,080 Speaker 1: problem that's not a medical condition in itself, but just 307 00:17:50,119 --> 00:17:54,320 Speaker 1: the fact that if you're headed towards Mars, or on Mars, 308 00:17:54,480 --> 00:17:59,040 Speaker 1: you are so far away from the nearest medical facility. Yeah, 309 00:17:59,080 --> 00:18:01,439 Speaker 1: you've got to have it all in the back, right, 310 00:18:01,520 --> 00:18:03,480 Speaker 1: you're ready to go. Yeah, what if you get a 311 00:18:03,560 --> 00:18:06,320 Speaker 1: kidney stone on Mars? You know? And the other thing 312 00:18:06,359 --> 00:18:08,679 Speaker 1: about the the exercise, because it easy to imagine, all right, 313 00:18:08,680 --> 00:18:11,520 Speaker 1: we'd have our our our drug hampers is completely filled 314 00:18:11,600 --> 00:18:14,199 Speaker 1: up and our our vitamins and our um and our 315 00:18:14,280 --> 00:18:17,520 Speaker 1: osto process medications. But then and we'll just be hitting 316 00:18:17,520 --> 00:18:20,479 Speaker 1: the treadmill the whole time. But you know, we've been 317 00:18:20,520 --> 00:18:24,080 Speaker 1: working with this problem for decades and and uh and 318 00:18:24,080 --> 00:18:26,959 Speaker 1: and experts still aren't really convinced, you know, what the 319 00:18:27,000 --> 00:18:31,000 Speaker 1: best method of exercises and if exercise really helps to 320 00:18:31,080 --> 00:18:35,040 Speaker 1: mitigate this, because you're again you're talking about constant ambient 321 00:18:35,119 --> 00:18:38,239 Speaker 1: gravitational pressure on the body and that's not something you 322 00:18:38,240 --> 00:18:41,560 Speaker 1: can you can really replicate with our current systems of 323 00:18:41,640 --> 00:18:44,239 Speaker 1: you know, treadmills or even some of these, uh, like 324 00:18:44,320 --> 00:18:48,760 Speaker 1: these force suits that the the Russians experimented within the past, 325 00:18:48,800 --> 00:18:51,280 Speaker 1: where they would be like this, we're just the act 326 00:18:51,280 --> 00:18:53,720 Speaker 1: of moving your arm would have a certain amount of 327 00:18:53,720 --> 00:18:58,800 Speaker 1: of of exercises. Yeah, the resistance suits, those are interesting, Yeah, 328 00:18:58,920 --> 00:19:01,600 Speaker 1: they're Um is a space musical by the name of 329 00:19:02,400 --> 00:19:05,040 Speaker 1: the American Astronaut, and there's a character that shows up 330 00:19:05,600 --> 00:19:08,840 Speaker 1: named body Suit, and he's this, uh, he's been living 331 00:19:08,840 --> 00:19:11,720 Speaker 1: in deep space for a long time and has has 332 00:19:11,760 --> 00:19:15,560 Speaker 1: one of these resistant suits on to keep his body strong. Meanwhile, 333 00:19:15,640 --> 00:19:20,919 Speaker 1: his father is just this stringy creature that's completely lost 334 00:19:20,960 --> 00:19:23,560 Speaker 1: all of his bone mass and as this enormous swollen head. 335 00:19:24,880 --> 00:19:28,520 Speaker 1: It's a yeah, um, it's it's a common exploration in 336 00:19:28,520 --> 00:19:30,880 Speaker 1: sci fi. I guess some of the heavier sci fi, 337 00:19:31,040 --> 00:19:35,439 Speaker 1: like Dan Simon's Hyperion books, there's a there's like a 338 00:19:35,520 --> 00:19:38,960 Speaker 1: race of humans that live in wayless environments and very 339 00:19:39,080 --> 00:19:44,159 Speaker 1: very tall and elongated, creepy. Well. I mean, actually, if 340 00:19:44,200 --> 00:19:48,240 Speaker 1: you've ever seen live footage of astronauts on the International 341 00:19:48,280 --> 00:19:51,000 Speaker 1: Space Station, you might have noticed that they look a 342 00:19:51,000 --> 00:19:54,399 Speaker 1: little weird, like, yeah, what, what exactly is wrong with 343 00:19:54,440 --> 00:19:59,080 Speaker 1: their bodies? That's an effect of weightlessness, where where body 344 00:19:59,119 --> 00:20:02,800 Speaker 1: fluids are read distributed up from the legs and into 345 00:20:02,920 --> 00:20:05,760 Speaker 1: the chest, shoulders, and heads. So if their face looks 346 00:20:05,800 --> 00:20:09,240 Speaker 1: puffy and they look they've got the kind of bodybuilder shoulders, 347 00:20:09,920 --> 00:20:13,960 Speaker 1: that's because of the microgravity environment. Yeah, there's so many 348 00:20:13,960 --> 00:20:16,920 Speaker 1: things we don't even necessarily think about. One that always 349 00:20:16,920 --> 00:20:19,960 Speaker 1: amazes me is how your bladder fills up in a 350 00:20:19,960 --> 00:20:23,880 Speaker 1: weightless environment. Yeah, because we've evolved to live in gravity. 351 00:20:23,920 --> 00:20:26,400 Speaker 1: So as our bladder fills up, that water is subject 352 00:20:26,440 --> 00:20:29,240 Speaker 1: to gravity, and as it starts getting a little bit, 353 00:20:29,560 --> 00:20:32,880 Speaker 1: a little bit towards the tipping point, we realize Hey, 354 00:20:32,920 --> 00:20:34,560 Speaker 1: I need to go to the bathroom. I should go 355 00:20:34,720 --> 00:20:38,400 Speaker 1: and relieve this. But if you're in a weightless environment, 356 00:20:38,920 --> 00:20:40,840 Speaker 1: it's not filling from the bottom up, it's just kind 357 00:20:40,840 --> 00:20:45,959 Speaker 1: of filling all around. So afternots don't often really realize 358 00:20:46,040 --> 00:20:50,600 Speaker 1: they have to go urinate until they've reached like maximum capacity, 359 00:20:50,760 --> 00:20:53,840 Speaker 1: like like almost you know, dangerous levels of full bladder. 360 00:20:53,920 --> 00:20:56,560 Speaker 1: Oh man, Yeah, so it's kind of so it kind 361 00:20:56,560 --> 00:21:00,080 Speaker 1: of transforms, you know, an ad adventurous adult in to 362 00:21:00,200 --> 00:21:03,240 Speaker 1: a toddler who suddenly realizes I've got to go to 363 00:21:03,240 --> 00:21:05,000 Speaker 1: the bathroom and there's nothing I can do to stop it. 364 00:21:05,040 --> 00:21:07,639 Speaker 1: All right, But that's all just in space flight, when 365 00:21:07,680 --> 00:21:10,560 Speaker 1: you're in this effectively zero G environment, the micro gravity 366 00:21:10,640 --> 00:21:14,639 Speaker 1: environment floating around, when you're on the International Space Station 367 00:21:14,720 --> 00:21:17,320 Speaker 1: for a number of months, you can eventually come back 368 00:21:17,320 --> 00:21:20,560 Speaker 1: to Earth and retrain. Your body might never be exactly 369 00:21:20,640 --> 00:21:22,560 Speaker 1: the same as it was before you went up to 370 00:21:22,600 --> 00:21:25,000 Speaker 1: the I S S, but you can you can regain 371 00:21:25,040 --> 00:21:28,919 Speaker 1: a lot of lost capacity. One question I have is 372 00:21:29,119 --> 00:21:31,359 Speaker 1: to what extent is that going to be true once 373 00:21:31,400 --> 00:21:34,600 Speaker 1: astronauts get out of the ship after six months in 374 00:21:34,640 --> 00:21:38,159 Speaker 1: weightlessness and then walk around on Mars, Because Mars is 375 00:21:38,200 --> 00:21:42,680 Speaker 1: not Earth right less gravity there, So you be you're, 376 00:21:42,760 --> 00:21:46,520 Speaker 1: you're you would certainly leave behind this, uh, this weightless 377 00:21:46,600 --> 00:21:50,600 Speaker 1: environment of space travel, but you're not. You're certainly not 378 00:21:50,640 --> 00:21:53,120 Speaker 1: going back to Earth levels of gravity. You're going back 379 00:21:53,119 --> 00:21:56,679 Speaker 1: to something far lighter. Yeah, and so what is the 380 00:21:56,720 --> 00:22:02,119 Speaker 1: effect of living in sixty less gravity for years at 381 00:22:02,160 --> 00:22:04,520 Speaker 1: a time or the rest of your life. I don't 382 00:22:04,560 --> 00:22:07,760 Speaker 1: think anybody knows the answer to that question yet. Yeah, 383 00:22:07,800 --> 00:22:10,120 Speaker 1: it's just not something we've we've dealt with thus far. 384 00:22:10,320 --> 00:22:13,040 Speaker 1: And and and this is again an area where are 385 00:22:13,480 --> 00:22:18,320 Speaker 1: our research into ways to mitigate uh space flight osteopenia 386 00:22:18,760 --> 00:22:21,040 Speaker 1: has to improve. Is we have to figure out better 387 00:22:21,080 --> 00:22:25,359 Speaker 1: ways to tackle it with improved exercise system improve pharmaceuticals 388 00:22:25,440 --> 00:22:29,800 Speaker 1: and vitamin regiments. So it's it's hard to say. Yeah. 389 00:22:29,840 --> 00:22:32,280 Speaker 1: And then there are a whole host of other effects 390 00:22:32,280 --> 00:22:35,760 Speaker 1: we observe in astronauts and witless environments that are not 391 00:22:35,880 --> 00:22:39,520 Speaker 1: even related to the decay of muscle and bone density. 392 00:22:39,880 --> 00:22:43,159 Speaker 1: One example would be vision. We ever read about astronaut 393 00:22:43,240 --> 00:22:46,000 Speaker 1: vision impairment? Yeah, this is the thing. So on Earth, 394 00:22:46,080 --> 00:22:48,600 Speaker 1: like we were saying, our circulatory system has adapted to 395 00:22:48,640 --> 00:22:52,320 Speaker 1: give us even blood circulation despite the effects of gravity 396 00:22:52,400 --> 00:22:55,520 Speaker 1: yanking our blood towards the ground. So without the gravity, 397 00:22:56,000 --> 00:23:00,439 Speaker 1: your body overcompensates for gravity that isn't there and puts 398 00:23:00,520 --> 00:23:02,959 Speaker 1: way too much blood into your head, so you can 399 00:23:03,040 --> 00:23:07,840 Speaker 1: essentially read out without without the aid of the jet fighter. Well, 400 00:23:08,000 --> 00:23:11,600 Speaker 1: the it's actually the continuous effects of this increased blood 401 00:23:11,600 --> 00:23:14,440 Speaker 1: pressure in the head that caused the biggest problem. One 402 00:23:14,480 --> 00:23:18,000 Speaker 1: common symptom is far sightedness. Another thing is this thing 403 00:23:18,040 --> 00:23:21,760 Speaker 1: called cotton wool spots in your field of vision, and 404 00:23:21,800 --> 00:23:24,199 Speaker 1: that's caused by damage to the nerve fibers in the 405 00:23:24,200 --> 00:23:27,160 Speaker 1: back of the eye. So now we've got a few things. 406 00:23:27,800 --> 00:23:30,359 Speaker 1: When you get out of the ship, so you've just 407 00:23:30,520 --> 00:23:35,720 Speaker 1: arrived at Mars, you might have decreased bone and muscle density, 408 00:23:36,240 --> 00:23:39,720 Speaker 1: possibly brain damage if you didn't take you know, your 409 00:23:39,880 --> 00:23:45,440 Speaker 1: proper radiation shielding, and impaired vision. That's not a way 410 00:23:45,440 --> 00:23:50,719 Speaker 1: to build a colony. So I I don't know if 411 00:23:50,760 --> 00:23:53,800 Speaker 1: the impaired vision effects would carry over onto Mars either 412 00:23:54,000 --> 00:23:57,680 Speaker 1: or to what extent the Mars gravity would help solve 413 00:23:57,720 --> 00:24:00,400 Speaker 1: the problem. Again, we don't know about the long term 414 00:24:00,400 --> 00:24:03,359 Speaker 1: effects of living on reduced gravity. All Right, we're gonna 415 00:24:03,359 --> 00:24:05,760 Speaker 1: take a quick break and when we come back, we 416 00:24:05,840 --> 00:24:19,119 Speaker 1: will consider the Martian dusty. Alright, we're back, as we've 417 00:24:19,160 --> 00:24:23,120 Speaker 1: been discussing. Yeah, we've arrived at Mars and we've we've 418 00:24:23,160 --> 00:24:28,680 Speaker 1: just been ravaged by a micro gravity radiation and now 419 00:24:28,720 --> 00:24:32,199 Speaker 1: we're actually on the surface and here comes the Martian dust. Right, 420 00:24:32,240 --> 00:24:34,359 Speaker 1: So we've dealt with the main threats to health and 421 00:24:34,400 --> 00:24:37,119 Speaker 1: well being that people bring up, the micro gravity and 422 00:24:37,119 --> 00:24:39,560 Speaker 1: the radiation. But it turns out there are a bunch 423 00:24:39,600 --> 00:24:41,960 Speaker 1: of other ones, and and the Martian dust is a 424 00:24:42,040 --> 00:24:46,359 Speaker 1: particularly interesting one to me. In December of nineteen seventy two, 425 00:24:46,440 --> 00:24:51,000 Speaker 1: the astronauts Harrison Schmidt and Eugene turn On of Apollo 426 00:24:51,080 --> 00:24:54,440 Speaker 1: seventeen landed on the Moon and they were carrying out 427 00:24:54,480 --> 00:24:59,000 Speaker 1: some surface missions and once upon returning from the Taurus 428 00:24:59,080 --> 00:25:01,760 Speaker 1: Littro Valley, which is close to the Sea of Serenity 429 00:25:01,800 --> 00:25:05,600 Speaker 1: on the Moon, the two astronauts re entered the lunar 430 00:25:05,680 --> 00:25:12,760 Speaker 1: module and Harrison Schmidt reported respiratory distress from inhaling particles 431 00:25:12,800 --> 00:25:16,040 Speaker 1: of moon dust that they had tracked into the capsule 432 00:25:16,160 --> 00:25:18,760 Speaker 1: with them. Uh and to make it sound cute, he 433 00:25:18,800 --> 00:25:22,159 Speaker 1: called it lunar dust hay fever. That does sound cute, 434 00:25:22,240 --> 00:25:26,600 Speaker 1: but the actual situation isn't so cute. And while working 435 00:25:26,600 --> 00:25:28,680 Speaker 1: on the surface of the Moon, the Apollo astronauts have 436 00:25:28,680 --> 00:25:32,440 Speaker 1: have noticed a consistently annoying and troubling thing about the Moon. 437 00:25:32,880 --> 00:25:37,680 Speaker 1: It's covered in this sticky, abrasive dust that true fact, 438 00:25:37,800 --> 00:25:42,040 Speaker 1: smells like gunpowder, they all report, and it gets all 439 00:25:42,080 --> 00:25:46,840 Speaker 1: over everything. Astronauts found that it's these sharp edged, abrasive 440 00:25:47,000 --> 00:25:51,160 Speaker 1: dust grains, almost almost like a tiny shards of glass, 441 00:25:51,200 --> 00:25:54,159 Speaker 1: and they would embed themselves and surfaces, and it was 442 00:25:54,200 --> 00:25:57,640 Speaker 1: just impossible to prevent astronauts from bringing it with them 443 00:25:57,680 --> 00:26:00,439 Speaker 1: when they returned from outside. And this is proven a 444 00:26:00,440 --> 00:26:03,520 Speaker 1: tough problem for anybody imagining a return trip to the 445 00:26:03,520 --> 00:26:06,880 Speaker 1: Moon or a Moon colony, because if the trip involves 446 00:26:06,920 --> 00:26:10,800 Speaker 1: any extra vehicular activity, moon colonists are going to have 447 00:26:10,880 --> 00:26:13,879 Speaker 1: this dust problem. Yeah, I've read about some of this, 448 00:26:13,960 --> 00:26:16,560 Speaker 1: but before it's it's it's interesting. You just see those 449 00:26:16,560 --> 00:26:19,200 Speaker 1: images of the Moon and you you kind of default 450 00:26:19,240 --> 00:26:21,800 Speaker 1: to imagining it is being covered with you know, just 451 00:26:21,920 --> 00:26:26,480 Speaker 1: sand or maybe maybe like a fine flower, uh consistency, 452 00:26:26,560 --> 00:26:31,040 Speaker 1: but it's it's it's rough stuff and it gets over everything. 453 00:26:31,480 --> 00:26:34,800 Speaker 1: Another aspect is that again it's dark. It's like, uh, 454 00:26:35,080 --> 00:26:39,440 Speaker 1: and it's it's dark gray kind of material, and you're 455 00:26:39,480 --> 00:26:41,640 Speaker 1: on the Moon and it's say, it coats your instruments, 456 00:26:42,000 --> 00:26:44,760 Speaker 1: it coats your equipment, maybe it coats your space suit, 457 00:26:45,200 --> 00:26:47,679 Speaker 1: and it's gonna cause whatever it's coding to start heat up, 458 00:26:47,720 --> 00:26:49,639 Speaker 1: to heat up in the sun because this is the 459 00:26:50,320 --> 00:26:54,200 Speaker 1: dust itself will absorbed the solar radiation. So suddenly it's 460 00:26:54,240 --> 00:26:56,720 Speaker 1: like you're wearing a black coat on a sunny day 461 00:26:57,119 --> 00:26:59,399 Speaker 1: and you're just getting hotter and hotter because of the 462 00:26:59,480 --> 00:27:01,439 Speaker 1: dust on Yeah, and you don't want to sweat like 463 00:27:01,440 --> 00:27:05,040 Speaker 1: a pig on the moon, So you could essentially wind 464 00:27:05,119 --> 00:27:10,960 Speaker 1: up cooked via lunar dust. Scary thought, but that's the Moon. 465 00:27:12,000 --> 00:27:16,360 Speaker 1: Mars might have a similar problem, but basically even more horrible. 466 00:27:17,200 --> 00:27:22,359 Speaker 1: So one problem is fine grains of silicate materials. So 467 00:27:22,440 --> 00:27:26,080 Speaker 1: here on Earth, human miners often suffer from a disease 468 00:27:26,160 --> 00:27:29,119 Speaker 1: called silicosis. If you're working in like a mine or 469 00:27:29,119 --> 00:27:33,080 Speaker 1: a quarry, or if you work in tunneling, drilling, sand blasting, 470 00:27:33,240 --> 00:27:36,400 Speaker 1: glass works, any of these things, your work environment can 471 00:27:36,440 --> 00:27:41,879 Speaker 1: produce extremely fine grain particles of silicon dioxide or silica 472 00:27:42,080 --> 00:27:46,120 Speaker 1: dust in the air and silica is a totally common mineral. 473 00:27:46,240 --> 00:27:48,760 Speaker 1: It's not one of those things to get upset about. 474 00:27:48,840 --> 00:27:53,000 Speaker 1: As a material itself, sand is mostly sica. If ingested 475 00:27:53,040 --> 00:27:56,959 Speaker 1: in reasonable quantities orally, it's non toxic. But if you 476 00:27:57,040 --> 00:28:01,800 Speaker 1: breathe in extremely fine particles silica dust, they can become 477 00:28:01,880 --> 00:28:06,400 Speaker 1: embedded in your lungs and your body can't remove them, 478 00:28:06,520 --> 00:28:09,280 Speaker 1: so depending on the level and length of exposure, this 479 00:28:09,320 --> 00:28:13,560 Speaker 1: can lead to irritation, swelling, and difficulty breathing, and eventually 480 00:28:13,600 --> 00:28:17,639 Speaker 1: to progressive massive fibrosis, which means your lungs are pretty 481 00:28:17,720 --> 00:28:21,679 Speaker 1: much destroyed, and long term exposure to crystalline silica is 482 00:28:21,720 --> 00:28:24,399 Speaker 1: also considered a cancer risk. This is this is a 483 00:28:24,480 --> 00:28:30,280 Speaker 1: bad recipe for long health. Martian soil contains fine grained 484 00:28:30,320 --> 00:28:34,040 Speaker 1: silicate particles that are largely different from the particles of 485 00:28:34,119 --> 00:28:36,879 Speaker 1: quartz silica that we'd risk breathing on Earth, though they 486 00:28:36,920 --> 00:28:40,720 Speaker 1: might produce similar or even worse effects. So years ago, 487 00:28:40,840 --> 00:28:45,560 Speaker 1: researchers at Stony Brook University in New York pulverized samples 488 00:28:45,600 --> 00:28:48,320 Speaker 1: of the most common basaltic minerals you'd find in the 489 00:28:48,320 --> 00:28:53,360 Speaker 1: Martian soil feldspar, pyroxene, and olivine to see what would 490 00:28:53,360 --> 00:28:56,960 Speaker 1: happen when this faux Martian dust reacted with moisture the 491 00:28:57,000 --> 00:28:59,479 Speaker 1: way it would with the moisture in your lungs if 492 00:28:59,520 --> 00:29:02,640 Speaker 1: you breathe in And the results were kind of gross. 493 00:29:03,440 --> 00:29:05,960 Speaker 1: A mixture of five million liters of water with a 494 00:29:05,960 --> 00:29:10,080 Speaker 1: couple hundred milligrams of the synthetic Mars dust reacted to 495 00:29:10,120 --> 00:29:16,000 Speaker 1: create hydrogen peroxide, So fizzy fizzy party times hydroxyl and 496 00:29:16,160 --> 00:29:21,440 Speaker 1: a negatively charged oxygen ion called superoxide. Not not really 497 00:29:21,480 --> 00:29:24,840 Speaker 1: things you want in your lungs. In addition to this, 498 00:29:24,920 --> 00:29:29,320 Speaker 1: scientists believe Martian soil contains perchlorates, which have detrimental effects 499 00:29:29,320 --> 00:29:32,680 Speaker 1: on the thyroid and hormone production in the human body. 500 00:29:33,280 --> 00:29:37,480 Speaker 1: So not only is it likely to cause irritation and 501 00:29:37,880 --> 00:29:41,720 Speaker 1: lung diseases if inhaled chronically over time, it can also 502 00:29:41,840 --> 00:29:45,960 Speaker 1: poison you and he gets worse. On Mars, there are 503 00:29:46,120 --> 00:29:48,880 Speaker 1: dust storms of titanic proportions. You don't really have to 504 00:29:48,920 --> 00:29:51,840 Speaker 1: worry about dust storms on the moon. On Mars, you do. 505 00:29:51,920 --> 00:29:54,480 Speaker 1: The dust storms there can become so bad they can 506 00:29:54,520 --> 00:29:59,320 Speaker 1: become planet wide dust storms engulfing the entire surface. So 507 00:29:59,440 --> 00:30:04,560 Speaker 1: welcome to planet poison storm. Don't breathe in. As far 508 00:30:04,560 --> 00:30:07,080 Speaker 1: as I'm aware, there is no known solution to this 509 00:30:07,120 --> 00:30:10,080 Speaker 1: problem yet except maybe just never going outside. I guess 510 00:30:10,080 --> 00:30:13,520 Speaker 1: if you seal yourself off in an airtight container and 511 00:30:13,760 --> 00:30:15,760 Speaker 1: you know you're never going in or out, then you 512 00:30:15,800 --> 00:30:19,360 Speaker 1: could probably be okay. But then what are you doing right? 513 00:30:19,400 --> 00:30:22,800 Speaker 1: As right? So I read in the past, I think, 514 00:30:22,800 --> 00:30:26,160 Speaker 1: in the context of Moon exploration, about NASA researchers looking 515 00:30:26,160 --> 00:30:30,440 Speaker 1: into designs for things like handheld vacuums and airlocks. And 516 00:30:30,800 --> 00:30:33,280 Speaker 1: I don't know where that research is today, but it 517 00:30:33,320 --> 00:30:35,800 Speaker 1: seems like even that would have trouble completely solving the 518 00:30:35,880 --> 00:30:39,160 Speaker 1: dust problem, because you only, what, are you just going 519 00:30:39,200 --> 00:30:42,280 Speaker 1: to bring an entire ship of vacuums that steadily break 520 00:30:42,320 --> 00:30:46,040 Speaker 1: down from all the particles that are surging through the system. Yeah, 521 00:30:46,040 --> 00:30:47,920 Speaker 1: and then there's the question of how the dust would 522 00:30:47,920 --> 00:30:51,880 Speaker 1: actually affect the equipment in your habitat. So is the 523 00:30:51,960 --> 00:30:55,120 Speaker 1: dust going to be clogging air filters, is it going 524 00:30:55,160 --> 00:30:57,840 Speaker 1: to be getting into instruments that you need to perform 525 00:30:57,880 --> 00:31:02,440 Speaker 1: your scientific work? And so, by and large, the dust 526 00:31:02,560 --> 00:31:05,680 Speaker 1: is going to be a huge problem, and it's something 527 00:31:05,760 --> 00:31:08,080 Speaker 1: we really need to think about if we're actually going 528 00:31:08,120 --> 00:31:10,880 Speaker 1: to be sending people to Mars. And that's assuming that 529 00:31:10,920 --> 00:31:14,040 Speaker 1: the dust doesn't suddenly turn into a giant hand like 530 00:31:14,120 --> 00:31:17,760 Speaker 1: the Stephen King short story Beach World. Right, yeah, because 531 00:31:17,760 --> 00:31:20,200 Speaker 1: then it's a whole set of set of problems in 532 00:31:20,200 --> 00:31:23,200 Speaker 1: addition to just breathing it in or or wait a minute, 533 00:31:23,240 --> 00:31:25,800 Speaker 1: what does the dust do in mission to Mars? Oh? 534 00:31:26,320 --> 00:31:28,560 Speaker 1: You know, I don't think I ever saw mission to Mars. Well, 535 00:31:28,640 --> 00:31:32,920 Speaker 1: you're one of the lucky ones, all right, Well, the 536 00:31:32,960 --> 00:31:35,680 Speaker 1: next thing to think about, you know, on the surface 537 00:31:35,720 --> 00:31:40,120 Speaker 1: seems a little less intensive. Uh, you know, it's not. 538 00:31:40,480 --> 00:31:44,880 Speaker 1: It's not as as crazy as dust that's gradually killing you, 539 00:31:45,080 --> 00:31:48,240 Speaker 1: or or the loss of phone mass, or even the 540 00:31:48,520 --> 00:31:51,640 Speaker 1: harmful effects of radiation. But it is very real, and 541 00:31:51,680 --> 00:31:54,040 Speaker 1: you can think of it as just an additional thing 542 00:31:54,120 --> 00:31:57,320 Speaker 1: you would have to deal with on Mars. And that 543 00:31:57,680 --> 00:32:01,360 Speaker 1: is how life on Mars would affect your circadian rhythm. Um. 544 00:32:01,400 --> 00:32:03,440 Speaker 1: And I have to admit I never really thought about 545 00:32:03,480 --> 00:32:07,479 Speaker 1: this myself, But a Mars day called a soul is 546 00:32:07,520 --> 00:32:10,800 Speaker 1: thirty nine minutes and thirty five seconds longer than an 547 00:32:10,800 --> 00:32:15,800 Speaker 1: Earth day. Oh that that's just close enough that it 548 00:32:15,960 --> 00:32:21,160 Speaker 1: seems maybe even worse than if it were way different. Well, 549 00:32:21,280 --> 00:32:24,120 Speaker 1: you know it, Yeah, and on the surface, it doesn't 550 00:32:24,120 --> 00:32:25,760 Speaker 1: maybe it maybe it doesn't sound like much. You might 551 00:32:25,800 --> 00:32:27,400 Speaker 1: even think, oh, it's a good thing. I can watch 552 00:32:27,560 --> 00:32:31,320 Speaker 1: one extra episode of of my favorite hour long show 553 00:32:31,680 --> 00:32:34,400 Speaker 1: Fans Commercials. Right, it's forty minutes. I can get it in, right, 554 00:32:34,560 --> 00:32:37,560 Speaker 1: maybe forty minutes of extra sleep. But we actually have 555 00:32:37,720 --> 00:32:42,240 Speaker 1: some experience dealing with the problems of an extra forty 556 00:32:42,240 --> 00:32:45,600 Speaker 1: odd minutes in the day. Uh As, every time NASA 557 00:32:45,680 --> 00:32:49,360 Speaker 1: lands are over on Mars operations teams have to adapt 558 00:32:49,440 --> 00:32:52,520 Speaker 1: to the Martians schedule. There's a there's a great article 559 00:32:52,520 --> 00:32:55,000 Speaker 1: that deals with this that appeared in Scientific American by 560 00:32:55,040 --> 00:32:58,040 Speaker 1: Katie It's an article by Katie Worth titled step into 561 00:32:58,040 --> 00:33:00,840 Speaker 1: the Twilight Zone? Can Earthlings adjust to a longer day 562 00:33:00,840 --> 00:33:05,880 Speaker 1: on Mars? And she describes how those extra forty minutes, 563 00:33:06,240 --> 00:33:08,800 Speaker 1: you know, they weren't bad at first, but you have 564 00:33:08,920 --> 00:33:11,120 Speaker 1: the you have this crew and they're dealing with with 565 00:33:11,120 --> 00:33:13,080 Speaker 1: with the Martian day, they're dealing with the Earth day, 566 00:33:13,080 --> 00:33:16,040 Speaker 1: and they're dealing with both across multiple time zones. So 567 00:33:16,120 --> 00:33:19,280 Speaker 1: the forty minutes just begins to add up over time. 568 00:33:19,440 --> 00:33:23,200 Speaker 1: It just ends up causing high levels of exhaustion, so 569 00:33:23,240 --> 00:33:26,120 Speaker 1: they end up trying limiting shifts to four days in 570 00:33:26,120 --> 00:33:29,400 Speaker 1: a row no more. But even this uh causes the 571 00:33:29,400 --> 00:33:33,720 Speaker 1: martian minutes to catch up with you after time. Um. Yeah, 572 00:33:33,720 --> 00:33:36,240 Speaker 1: because you have to imagine it. It's not just that 573 00:33:36,280 --> 00:33:39,320 Speaker 1: you would get an extra long day one day and 574 00:33:39,360 --> 00:33:42,800 Speaker 1: then you get to sleep and reset every day. This 575 00:33:43,000 --> 00:33:46,240 Speaker 1: accumulation of the extra forty minutes is adding on to 576 00:33:46,360 --> 00:33:50,920 Speaker 1: the accumulation of the day before. Now it's like continuous 577 00:33:51,000 --> 00:33:55,240 Speaker 1: jet lag. Now we're in for some good news because 578 00:33:55,680 --> 00:33:57,920 Speaker 1: one of the things is once you actually get to Mars, 579 00:33:58,360 --> 00:34:01,000 Speaker 1: you're at least going to have, you know, cycles of 580 00:34:01,080 --> 00:34:03,320 Speaker 1: day and night to tie in with your circadian rhythm. 581 00:34:03,400 --> 00:34:06,920 Speaker 1: So it's thought that you would probably adjust pretty well 582 00:34:07,000 --> 00:34:10,680 Speaker 1: to this extra forty minutes once you're on the planet. Now, 583 00:34:11,040 --> 00:34:12,960 Speaker 1: of course, one of the problems is that you've, of 584 00:34:13,000 --> 00:34:16,399 Speaker 1: course you've been traveling through space completely cut off from 585 00:34:16,440 --> 00:34:18,239 Speaker 1: cycles of night and day unless there's some sort of 586 00:34:18,280 --> 00:34:22,879 Speaker 1: artificial stimulation of your circadian rhythm and uh, and you're 587 00:34:22,880 --> 00:34:26,279 Speaker 1: still going to have to on some level deal with 588 00:34:26,400 --> 00:34:30,399 Speaker 1: time back come um. And this is where you get 589 00:34:30,400 --> 00:34:32,840 Speaker 1: into questions about, all right, what what's going to be 590 00:34:32,880 --> 00:34:36,960 Speaker 1: the degree of communication with the home world. Uh. I'm guessing, 591 00:34:37,040 --> 00:34:40,200 Speaker 1: especially in an early low budget visit to Mars, is 592 00:34:40,200 --> 00:34:42,720 Speaker 1: gonna be pretty minimal. You're not gonna have any direct 593 00:34:42,719 --> 00:34:46,040 Speaker 1: skype conversations with your family back home. Now, you're just 594 00:34:46,080 --> 00:34:51,080 Speaker 1: gonna be broadcasting your reality television show. Yeah, and with 595 00:34:51,080 --> 00:34:54,200 Speaker 1: with some tape delay, right. But um, but the people 596 00:34:54,200 --> 00:34:57,040 Speaker 1: back home, the people looking after you and uh and 597 00:34:57,040 --> 00:34:59,120 Speaker 1: and seeing how operations are going, they're going to be 598 00:34:59,160 --> 00:35:01,440 Speaker 1: the one suffering from that extra forty minutes is they 599 00:35:01,480 --> 00:35:06,759 Speaker 1: have to simultaneously live into different time zones at once. Um. 600 00:35:06,800 --> 00:35:09,279 Speaker 1: And this this plays into another area that I've thought 601 00:35:09,320 --> 00:35:11,440 Speaker 1: about before too, like how do we end up keeping 602 00:35:11,480 --> 00:35:15,400 Speaker 1: track of time in general when we start looking towards 603 00:35:15,480 --> 00:35:18,560 Speaker 1: an an interplanetary future where you have different lengths of 604 00:35:18,640 --> 00:35:21,759 Speaker 1: days on different worlds, um, And then you have to 605 00:35:21,800 --> 00:35:25,240 Speaker 1: deal with the distance between those worlds, the time delay 606 00:35:25,400 --> 00:35:28,239 Speaker 1: and communication. In some cases, you might even have to 607 00:35:28,280 --> 00:35:32,000 Speaker 1: deal with noticeable time dilation exactly. Yeah, if you're talking 608 00:35:32,000 --> 00:35:35,560 Speaker 1: about like near light speed travel between different I mean, 609 00:35:35,960 --> 00:35:39,360 Speaker 1: the idea of time starts to lose its sense of 610 00:35:39,480 --> 00:35:43,640 Speaker 1: universality when you're talking about an interplanetary species. Yeah, it's 611 00:35:43,640 --> 00:35:47,960 Speaker 1: a great example of taking a very terrestrial concept and 612 00:35:48,000 --> 00:35:50,200 Speaker 1: then trying to make sense of it when we leave 613 00:35:50,239 --> 00:35:52,560 Speaker 1: the planet and I and you know, there we've we've 614 00:35:52,560 --> 00:35:54,680 Speaker 1: touched on religion in that sense, and you know, now 615 00:35:54,680 --> 00:35:57,920 Speaker 1: we're talking about time and the human body there. And 616 00:35:58,200 --> 00:36:00,839 Speaker 1: I can't even imagine how many different additions to that 617 00:36:00,840 --> 00:36:02,560 Speaker 1: there are that we're not even thinking about, all the 618 00:36:02,600 --> 00:36:07,319 Speaker 1: little things that add up to make interplanetary life all 619 00:36:07,400 --> 00:36:11,959 Speaker 1: the stranger totally. I I was trying to think about 620 00:36:11,960 --> 00:36:14,319 Speaker 1: it in the car on the way to work this morning, like, 621 00:36:14,400 --> 00:36:17,520 Speaker 1: how do you synchronize Mars time with Earth time? This 622 00:36:17,600 --> 00:36:20,440 Speaker 1: is only forty minutes difference each day, but what do 623 00:36:20,480 --> 00:36:24,440 Speaker 1: you do? Does does Mars just have thirty nine points 624 00:36:24,480 --> 00:36:27,120 Speaker 1: something extra minutes that go up on the clock and 625 00:36:27,160 --> 00:36:31,000 Speaker 1: then it resets to zero or I'm sure nobody would 626 00:36:31,000 --> 00:36:32,960 Speaker 1: actually try to do this, But for a minute, my 627 00:36:33,040 --> 00:36:34,799 Speaker 1: brain went to the place of would you just make 628 00:36:34,840 --> 00:36:37,560 Speaker 1: your minutes a little bit longer and have twenty four 629 00:36:37,560 --> 00:36:41,480 Speaker 1: hour days? Or yeah, it's very complicated and uh, and 630 00:36:41,520 --> 00:36:43,640 Speaker 1: again we have some experience with this in the way 631 00:36:43,680 --> 00:36:48,160 Speaker 1: that that NASA workers looking after any kind of operations 632 00:36:48,200 --> 00:36:51,680 Speaker 1: on Mars have to add that forty extra minutes into 633 00:36:51,680 --> 00:36:54,120 Speaker 1: their day. Well, I've got another way that we are 634 00:36:54,280 --> 00:36:57,799 Speaker 1: completely and totally adapted to Earth, and I think we 635 00:36:57,920 --> 00:37:02,880 Speaker 1: haven't fully considered the rampant cations of removing our culture 636 00:37:03,400 --> 00:37:08,600 Speaker 1: to a non Earth location, and that is microbiota. Ah, 637 00:37:08,640 --> 00:37:10,640 Speaker 1: and this this is uh, this is what I had 638 00:37:10,680 --> 00:37:13,320 Speaker 1: never thought of either. But even though on the past, 639 00:37:13,320 --> 00:37:15,560 Speaker 1: on the show, we've done a number of episodes dealing 640 00:37:15,560 --> 00:37:20,760 Speaker 1: with microbota and and how essentially we're just this population 641 00:37:21,120 --> 00:37:25,880 Speaker 1: of different bacteria, uh, in different microbiotic organisms that all 642 00:37:25,960 --> 00:37:29,080 Speaker 1: kind of work together as one spaceship. Oh totally. So. Yeah, 643 00:37:29,080 --> 00:37:32,239 Speaker 1: imagine you're a colonist on Mars. Where are you going 644 00:37:32,280 --> 00:37:36,120 Speaker 1: to get your food? I imagine you're gonna be growing it, right, yeah, 645 00:37:36,239 --> 00:37:40,000 Speaker 1: or or you know, getting it from the cube distancer. Yeah. 646 00:37:40,040 --> 00:37:41,880 Speaker 1: I mean, so, if you're an astronaut in the I 647 00:37:42,120 --> 00:37:44,920 Speaker 1: S S. You can live on vacuum packed shrimp cocktail 648 00:37:45,040 --> 00:37:47,239 Speaker 1: for a couple of months and that's not gonna kill you. 649 00:37:47,600 --> 00:37:49,840 Speaker 1: On Mars, you can't take all your food with you 650 00:37:50,000 --> 00:37:52,640 Speaker 1: and you go. You're gonna have to somehow grow crops 651 00:37:52,719 --> 00:37:56,680 Speaker 1: for yourself. Once you're at your semi permanent colony on Mars. 652 00:37:57,040 --> 00:38:00,800 Speaker 1: So maybe you could survive on hydroponics like rooting plants 653 00:38:00,800 --> 00:38:04,359 Speaker 1: in nutrient field water, or maybe even aeroponics like free 654 00:38:04,360 --> 00:38:06,799 Speaker 1: growing roots in the air fed by a nutrient rich 655 00:38:06,960 --> 00:38:11,160 Speaker 1: mist or spray. Makes sense, but there's a crucial question there. 656 00:38:11,160 --> 00:38:14,480 Speaker 1: We might not be taking into consideration what happens when 657 00:38:14,480 --> 00:38:17,480 Speaker 1: you drive a hundred and forty million mile wedge between 658 00:38:17,600 --> 00:38:24,480 Speaker 1: earthlings and earth soil, because Mars is a microbiotic desert. 659 00:38:24,600 --> 00:38:28,160 Speaker 1: And this is a digression, but I had to report 660 00:38:28,520 --> 00:38:34,520 Speaker 1: that Microsoft word wanted to change microbiotic desert to macrobiotic dessert. 661 00:38:34,880 --> 00:38:39,560 Speaker 1: That's how that's how appalled Microsoft is that the idea 662 00:38:39,680 --> 00:38:42,160 Speaker 1: of life on Lars right. So I read a really 663 00:38:42,200 --> 00:38:47,080 Speaker 1: interesting article about this in Slate from called our Guts 664 00:38:47,120 --> 00:38:51,040 Speaker 1: May Hate Mars, and the author, Michael Chorrost, makes the 665 00:38:51,080 --> 00:38:54,319 Speaker 1: interesting point that the soil we live on isn't just 666 00:38:54,480 --> 00:38:57,560 Speaker 1: an inert mass of stuff for plants to sit in. 667 00:38:58,120 --> 00:39:01,400 Speaker 1: It's an ecosystem. It's an ecosystem of its own, like 668 00:39:01,440 --> 00:39:04,560 Speaker 1: a rainforest or a coral reef, and it is teeming 669 00:39:04,600 --> 00:39:10,759 Speaker 1: with life, including bacteria, insects, worms, protozoa, and this ecosystem 670 00:39:10,800 --> 00:39:13,600 Speaker 1: is something that humans have never really tried to live 671 00:39:13,680 --> 00:39:17,800 Speaker 1: without for years at a time. So a few considerations. 672 00:39:18,080 --> 00:39:21,000 Speaker 1: One of them is the bacteria found in earth soil 673 00:39:21,080 --> 00:39:26,239 Speaker 1: is probably important for maintaining your microbiotic profile, because, as 674 00:39:26,480 --> 00:39:28,560 Speaker 1: we were alluding to a minute ago, your body isn't 675 00:39:28,600 --> 00:39:32,719 Speaker 1: just your body. You are a symbiant. You have legions 676 00:39:32,760 --> 00:39:35,880 Speaker 1: of benign microorganisms that live inside you, for example, in 677 00:39:35,920 --> 00:39:39,440 Speaker 1: your digestive system. And without healthy gut flora, humans can 678 00:39:39,440 --> 00:39:43,480 Speaker 1: suffer serious consequences Like what happens to you if you 679 00:39:43,600 --> 00:39:47,439 Speaker 1: don't have healthy gut flora. A lot of bad things 680 00:39:47,520 --> 00:39:51,640 Speaker 1: gonna happen. I mean, at the very least diarrhea in space, yeah, 681 00:39:51,920 --> 00:39:54,279 Speaker 1: which is a bad thing to happen in space. Yeah. 682 00:39:54,320 --> 00:39:56,960 Speaker 1: And you know, this reminds me too of some past 683 00:39:56,960 --> 00:39:59,759 Speaker 1: episodes we've done on the show dealing with the problems 684 00:40:00,000 --> 00:40:02,839 Speaker 1: of creating all these artificial environments that we live in now, 685 00:40:02,960 --> 00:40:05,440 Speaker 1: just talking about our our office spaces, where you have 686 00:40:05,480 --> 00:40:10,480 Speaker 1: an entirely different microbiotic profile that emerges because it is 687 00:40:10,760 --> 00:40:15,520 Speaker 1: separated from the soil, separated from the natural microbiotic environment 688 00:40:15,760 --> 00:40:17,560 Speaker 1: in which we live. And that's just here on Earth. 689 00:40:17,760 --> 00:40:21,040 Speaker 1: That's your workplace. Yeah, and so in this article, Chorist 690 00:40:21,120 --> 00:40:23,759 Speaker 1: points out that scientists say organisms that live in the 691 00:40:23,800 --> 00:40:29,040 Speaker 1: earth soil also provide countless quote ecosystem services that go 692 00:40:29,160 --> 00:40:31,840 Speaker 1: unnoticed but which are really important for keeping the rest 693 00:40:31,880 --> 00:40:35,000 Speaker 1: of life on Earth running smoothly. And these services include 694 00:40:35,000 --> 00:40:39,000 Speaker 1: things like the breakdown of dead organic matter, water filtration, 695 00:40:39,160 --> 00:40:44,120 Speaker 1: carbon dioxide cycling, and he cites Justin L. Sonnenberg, a 696 00:40:44,200 --> 00:40:48,479 Speaker 1: microbiologist and immunologists from the Stanford School of Medicine, who 697 00:40:48,520 --> 00:40:51,040 Speaker 1: also says a couple of really interesting things. One of 698 00:40:51,080 --> 00:40:55,080 Speaker 1: them is that the soil bacteria on Earth might make 699 00:40:55,280 --> 00:40:59,440 Speaker 1: your food better. So when you grow crops in the 700 00:40:59,800 --> 00:41:03,160 Speaker 1: t eaming micro jungle of Earth's soil, the plants have 701 00:41:03,239 --> 00:41:05,839 Speaker 1: to face off against enemies. They have to face off 702 00:41:05,840 --> 00:41:09,600 Speaker 1: against predators parasites of the ecosystem, and this causes the 703 00:41:09,640 --> 00:41:12,400 Speaker 1: plants to you know, be like Rocky when in the 704 00:41:12,440 --> 00:41:16,120 Speaker 1: training montage. It makes the plant strong, and in getting strong, 705 00:41:16,160 --> 00:41:19,920 Speaker 1: they have to synthesize compounds like antioxidants that make the 706 00:41:19,960 --> 00:41:23,759 Speaker 1: plants more nutritious for us when we eat them. So 707 00:41:23,840 --> 00:41:28,200 Speaker 1: without having to fight off the microbiotic onslaught the plants, 708 00:41:28,280 --> 00:41:31,120 Speaker 1: we eat wouldn't do all the same beneficial things for 709 00:41:31,160 --> 00:41:33,799 Speaker 1: our bodies that they do here on Earth. And this 710 00:41:33,880 --> 00:41:36,880 Speaker 1: is just one example of the many ways the complexities 711 00:41:36,920 --> 00:41:39,720 Speaker 1: of earth soil contribute to our well being. The point 712 00:41:39,760 --> 00:41:42,120 Speaker 1: is we don't know all of the ways that earth 713 00:41:42,200 --> 00:41:44,720 Speaker 1: soil contributes to our well being and to what extent 714 00:41:45,360 --> 00:41:47,960 Speaker 1: we might be able to survive without it, and we 715 00:41:48,040 --> 00:41:50,640 Speaker 1: might face health and well being problems that are much 716 00:41:50,680 --> 00:41:52,920 Speaker 1: bigger than we could have expected. So we get to 717 00:41:53,000 --> 00:41:56,600 Speaker 1: Mars and we're flabby and fightless due to our our 718 00:41:56,640 --> 00:41:59,319 Speaker 1: bone and muscle loss, and then we're growing some sort 719 00:41:59,320 --> 00:42:03,480 Speaker 1: of hydropod pumpkin to eat that's equally flapping and fightless 720 00:42:03,480 --> 00:42:05,719 Speaker 1: because it doesn't have to deal with the with the 721 00:42:05,840 --> 00:42:10,040 Speaker 1: with the natural uh predators and microbiota that it has 722 00:42:10,080 --> 00:42:13,719 Speaker 1: to that it has evolved to combat. Yeah, how many 723 00:42:13,760 --> 00:42:17,640 Speaker 1: ways Mars would make us soft? Well. So there's one 724 00:42:17,640 --> 00:42:20,200 Speaker 1: potential solution, right, What if we just shipped a bunch 725 00:42:20,239 --> 00:42:23,560 Speaker 1: of soil with us two Mars. So you just pack 726 00:42:23,680 --> 00:42:26,960 Speaker 1: up dirt from Earth and you take it and you 727 00:42:27,080 --> 00:42:30,239 Speaker 1: protected along the way because you don't want irradiated soil either, 728 00:42:30,840 --> 00:42:33,000 Speaker 1: and then you grow your crops in that would would 729 00:42:33,040 --> 00:42:36,560 Speaker 1: that work. Probably not, and there are a couple of reasons. 730 00:42:36,560 --> 00:42:38,920 Speaker 1: One of the things is that we've alluded to already 731 00:42:39,000 --> 00:42:43,480 Speaker 1: is cost. It's unbelievably expensive to put mass into orbit, 732 00:42:44,120 --> 00:42:46,319 Speaker 1: even more expensive to send it all the way out 733 00:42:46,360 --> 00:42:48,279 Speaker 1: of Earth's gravity well as we would need to do 734 00:42:48,360 --> 00:42:50,880 Speaker 1: to get it to Mars. The old figure that was 735 00:42:50,920 --> 00:42:53,640 Speaker 1: commonly cited was that it cost ten tho dollars per 736 00:42:53,680 --> 00:42:56,879 Speaker 1: pound to put stuff into low Earth orbit. With all 737 00:42:56,880 --> 00:42:59,879 Speaker 1: the private space launch technology that's currently emerging or will 738 00:43:00,000 --> 00:43:02,759 Speaker 1: emerge soon, that number is going to change. Who knows 739 00:43:02,800 --> 00:43:05,239 Speaker 1: what it is today or what it will be, but 740 00:43:05,360 --> 00:43:07,200 Speaker 1: I think it's safe to say it's still going to 741 00:43:07,280 --> 00:43:11,120 Speaker 1: be very, very expensive. And if you're on this corner 742 00:43:11,120 --> 00:43:13,759 Speaker 1: cutting Mars mission, they're not going to pony up for 743 00:43:13,760 --> 00:43:17,200 Speaker 1: the Earth soil. But there's a second point that's made 744 00:43:17,200 --> 00:43:21,320 Speaker 1: by Dr Sonnenberg in this article, and that point is 745 00:43:21,360 --> 00:43:24,360 Speaker 1: that it might not matter because in a closed environment 746 00:43:24,480 --> 00:43:27,200 Speaker 1: separated from the rest of Earth. Sonnenberg says that the 747 00:43:27,239 --> 00:43:31,200 Speaker 1: biodiversity of a soil sample will tend to decrease over 748 00:43:31,280 --> 00:43:35,480 Speaker 1: time until you no longer have the balanced microbiotic jungle 749 00:43:35,560 --> 00:43:38,600 Speaker 1: that you're looking for in this soil, so you end 750 00:43:38,680 --> 00:43:41,760 Speaker 1: up with just this dead soil. Essentially, the soil dies 751 00:43:41,880 --> 00:43:46,720 Speaker 1: like you you will. Yeah, this is interesting. It brings 752 00:43:46,760 --> 00:43:49,920 Speaker 1: mind to two things. First of all, even though it 753 00:43:49,960 --> 00:43:52,320 Speaker 1: would ultimately die, if we just needed to get soil 754 00:43:52,400 --> 00:43:55,960 Speaker 1: into orbit, we could take the Great Escape route, right 755 00:43:56,080 --> 00:43:58,320 Speaker 1: or the no I guess it was. I guess it 756 00:43:58,360 --> 00:44:00,440 Speaker 1: was the Great Escape And maybe it was Shoshank Redemption 757 00:44:00,480 --> 00:44:03,560 Speaker 1: as well, where they you have the problem of right, 758 00:44:03,560 --> 00:44:05,680 Speaker 1: if you're digging a hole to escape from a prison, 759 00:44:05,880 --> 00:44:07,799 Speaker 1: you have to do something with the dirt, so you 760 00:44:07,920 --> 00:44:10,319 Speaker 1: just you you you sneak it out a little bit 761 00:44:10,360 --> 00:44:12,600 Speaker 1: at a time, right, So maybe we just start putting 762 00:44:12,640 --> 00:44:16,320 Speaker 1: like a pocket full of dirt into on on board 763 00:44:16,360 --> 00:44:19,320 Speaker 1: each astronaut as they go up every space launch. Yeah, 764 00:44:19,680 --> 00:44:22,080 Speaker 1: well that's a great idea. Every time an astronaut goes 765 00:44:22,120 --> 00:44:24,399 Speaker 1: to the I S S, they just take some fistfuls 766 00:44:24,400 --> 00:44:26,320 Speaker 1: of soil. Yeah. Of course, again, it doesn't really do 767 00:44:26,440 --> 00:44:29,040 Speaker 1: much good if it's dead. But the other thing that 768 00:44:29,160 --> 00:44:32,200 Speaker 1: kept entering my mind is we consider the possibility of 769 00:44:32,760 --> 00:44:35,319 Speaker 1: organisms bringing their soil with them when they travel to 770 00:44:35,360 --> 00:44:39,799 Speaker 1: a new land in order to to thrive and to live. Is, 771 00:44:39,800 --> 00:44:43,440 Speaker 1: of course Dracula, because when Dracula left his home in 772 00:44:43,480 --> 00:44:47,400 Speaker 1: Transylvania to begin life in uh in London, he brought 773 00:44:47,440 --> 00:44:49,600 Speaker 1: with him a bunch of that that soil from his 774 00:44:49,680 --> 00:44:52,279 Speaker 1: native land, right. Yeah, And you actually see this in 775 00:44:52,440 --> 00:44:56,040 Speaker 1: ancient religious concepts, to like the idea that the God 776 00:44:56,080 --> 00:44:59,400 Speaker 1: I worship is the god of my lands, and if 777 00:44:59,440 --> 00:45:02,080 Speaker 1: I want to work ship my God in a foreign land, 778 00:45:02,360 --> 00:45:05,160 Speaker 1: I might want to take some soil from where I 779 00:45:05,200 --> 00:45:07,960 Speaker 1: came from with me, so I'm still technically on the 780 00:45:08,080 --> 00:45:11,200 Speaker 1: lands of my god when I worship him. Well, there 781 00:45:11,200 --> 00:45:13,320 Speaker 1: you go. There's some Internet that's probably some great food 782 00:45:13,320 --> 00:45:17,040 Speaker 1: for thought when it comes to any asked ancient astronauts scenarios, right, 783 00:45:17,040 --> 00:45:20,200 Speaker 1: because clearly this idea was handed down to us by 784 00:45:20,360 --> 00:45:23,440 Speaker 1: quote unquote gods who from another planet and had to 785 00:45:23,440 --> 00:45:26,200 Speaker 1: bring their own soil because they were aware of the 786 00:45:26,239 --> 00:45:29,399 Speaker 1: problems here of venturing to a new world caught off 787 00:45:29,600 --> 00:45:32,680 Speaker 1: from your your Earth. They were the reason the Colossus 788 00:45:32,680 --> 00:45:38,120 Speaker 1: of Rhodes was anatomically correct. Uh So, So ultimately, what 789 00:45:38,160 --> 00:45:42,040 Speaker 1: will life be like separate from from Earth dirt? We 790 00:45:42,160 --> 00:45:47,120 Speaker 1: just don't know, And the prospects are intriguingly scary. And 791 00:45:47,200 --> 00:45:49,360 Speaker 1: I think this is something that needs to be researched 792 00:45:49,440 --> 00:45:53,440 Speaker 1: very well before somebody makes that leap and says, Okay, 793 00:45:53,480 --> 00:45:57,799 Speaker 1: I'm a Martian now. But there's another risk that you 794 00:45:57,880 --> 00:46:00,160 Speaker 1: might run when you take the leap to say I'm 795 00:46:00,160 --> 00:46:03,759 Speaker 1: a Martian now, which is that you're not going to 796 00:46:03,880 --> 00:46:07,919 Speaker 1: have a lot of room on Mars, and you might 797 00:46:07,920 --> 00:46:12,480 Speaker 1: not necessarily have a lot to do on Mars, and 798 00:46:12,560 --> 00:46:14,640 Speaker 1: you're not going to be able to leave if you 799 00:46:14,680 --> 00:46:18,680 Speaker 1: want to write, and you might be confined in this 800 00:46:18,800 --> 00:46:22,560 Speaker 1: small space with several other people who you don't get 801 00:46:22,600 --> 00:46:26,200 Speaker 1: to get away from if you don't like them. And 802 00:46:26,200 --> 00:46:29,640 Speaker 1: and that's where space madness centers EQUI right, what we 803 00:46:29,640 --> 00:46:31,560 Speaker 1: we would be remiss if we did not talk about 804 00:46:31,560 --> 00:46:35,480 Speaker 1: space madness. So what is the deal with psychological health 805 00:46:35,600 --> 00:46:38,560 Speaker 1: on Mars. Well, you know, we've already touched a little 806 00:46:38,600 --> 00:46:41,719 Speaker 1: bit on how radiation could play into it. But but yeah, 807 00:46:41,760 --> 00:46:45,239 Speaker 1: just when we're dealing with the possibilities of dealing with 808 00:46:45,239 --> 00:46:50,239 Speaker 1: a confined space, not much variety in your environment. Um, 809 00:46:50,239 --> 00:46:52,880 Speaker 1: certainly on the trip there, but even once you get there, 810 00:46:52,920 --> 00:46:55,400 Speaker 1: you know you're you're you're stuck in this little shell. 811 00:46:55,440 --> 00:46:58,319 Speaker 1: Perhaps and then occasionally you get to engage in this 812 00:46:58,600 --> 00:47:04,000 Speaker 1: very stressful john out into the dust ravage landscape. But 813 00:47:04,000 --> 00:47:06,680 Speaker 1: but yeah, you're opening yourself up to the psychological effects 814 00:47:06,760 --> 00:47:12,160 Speaker 1: of of of isolation and seclusion. Uh, social isolation as 815 00:47:12,160 --> 00:47:14,440 Speaker 1: well as just you know, a lack of variety in 816 00:47:14,440 --> 00:47:16,680 Speaker 1: your environment. They've been you know, countless studies that have 817 00:47:16,719 --> 00:47:20,600 Speaker 1: looked at at how um isolation affects the human mind. 818 00:47:21,000 --> 00:47:24,319 Speaker 1: Now when we don't, you know, it comes back to 819 00:47:24,440 --> 00:47:26,759 Speaker 1: what we've evolved to live. And we've evolved to live 820 00:47:26,840 --> 00:47:31,080 Speaker 1: in this rather vibrant world of fixed and movable objects, 821 00:47:31,160 --> 00:47:35,319 Speaker 1: of interacting people and things. And when you leave that, 822 00:47:35,719 --> 00:47:40,120 Speaker 1: your brain kind of starts gnawing on it, creating the 823 00:47:40,120 --> 00:47:42,600 Speaker 1: the varied stimuli that you have come to it, your 824 00:47:42,600 --> 00:47:45,720 Speaker 1: brain has come to expect. Yeah, so we're here on Earth, 825 00:47:45,760 --> 00:47:49,080 Speaker 1: we're the mice on the mouse playground. On Mars, you 826 00:47:49,160 --> 00:47:51,880 Speaker 1: might be the mouse in the tiny cage with nothing 827 00:47:51,880 --> 00:47:55,719 Speaker 1: but a heroine button to push right and uh, and 828 00:47:55,960 --> 00:47:58,839 Speaker 1: you better hope that the heroine button works. And of course, yeah, 829 00:47:58,840 --> 00:48:02,200 Speaker 1: the whole time you're dealing with people, which, of course, 830 00:48:02,320 --> 00:48:05,239 Speaker 1: just in any given environment, can be stressful. And then 831 00:48:05,280 --> 00:48:07,959 Speaker 1: on top of that, you were traveling through space. You're 832 00:48:07,960 --> 00:48:10,480 Speaker 1: going to a disco. You're dealing with all the stress 833 00:48:10,560 --> 00:48:13,440 Speaker 1: of that, which is only going to exasperate into these 834 00:48:13,480 --> 00:48:18,120 Speaker 1: other conditions. Yeah, you're possibly having a lung conditions, serious 835 00:48:18,200 --> 00:48:20,920 Speaker 1: lung conditions. You might be suffering from cancer, you might 836 00:48:20,960 --> 00:48:24,239 Speaker 1: be suffering brain damage, you might be suffering weakness and 837 00:48:24,280 --> 00:48:27,880 Speaker 1: bone density loss, you might be suffering from digestive distress 838 00:48:27,960 --> 00:48:32,239 Speaker 1: from lack of proper microbiome. And then you've got to 839 00:48:32,280 --> 00:48:34,120 Speaker 1: deal with all these jerks and a tin ft by 840 00:48:34,160 --> 00:48:36,879 Speaker 1: tin foot space. Yeah, it's not surely not tin foot 841 00:48:36,920 --> 00:48:39,240 Speaker 1: by tin foot. I just threw that out there. However 842 00:48:39,239 --> 00:48:42,240 Speaker 1: big the space would be. Let's hope it's bigger than that. Yeah, 843 00:48:42,719 --> 00:48:45,000 Speaker 1: it's uh. You know, it's an area that that NASA 844 00:48:45,000 --> 00:48:47,359 Speaker 1: has been looking into for a while, but it's also 845 00:48:47,400 --> 00:48:50,760 Speaker 1: an area that we haven't had an extensive amount of 846 00:48:50,920 --> 00:48:54,279 Speaker 1: research on because for the most part, space flights are 847 00:48:54,320 --> 00:48:58,160 Speaker 1: pretty busy, even when you're dealing with these longer johns 848 00:48:58,239 --> 00:49:01,200 Speaker 1: up to the I s s, because you have a 849 00:49:01,200 --> 00:49:03,040 Speaker 1: lot a lot of that time is taken up by 850 00:49:03,120 --> 00:49:06,320 Speaker 1: you know, just getting acclimatized to the orbital environment, forcing 851 00:49:06,360 --> 00:49:11,040 Speaker 1: down your food making yourself sleep, braving the indignities of 852 00:49:11,120 --> 00:49:14,520 Speaker 1: orbital toilet use, and then of course conducting lots of experiments, 853 00:49:14,520 --> 00:49:17,080 Speaker 1: repairs and all the exercise you have to do. Yeah, 854 00:49:17,160 --> 00:49:21,080 Speaker 1: hitting that that coldbart treadmill up there. Um, there's plenty 855 00:49:21,120 --> 00:49:23,240 Speaker 1: to do. So we're not we're not as yet dealing 856 00:49:23,320 --> 00:49:27,799 Speaker 1: with the long term, uh, solitude issues, of the very 857 00:49:27,880 --> 00:49:31,480 Speaker 1: long term isolation issues, and people don't spend you know, 858 00:49:32,040 --> 00:49:36,200 Speaker 1: six to twelve years of Yeah, but of course NASA 859 00:49:36,239 --> 00:49:39,239 Speaker 1: has been looking into it, and they've studied how work, entertainment, 860 00:49:39,239 --> 00:49:42,800 Speaker 1: and food can conquer the effects of solitude. The agency 861 00:49:42,840 --> 00:49:46,240 Speaker 1: even invested one point seventy four million in a virtual 862 00:49:46,280 --> 00:49:50,240 Speaker 1: space station, a computer program designed to council astronauts about 863 00:49:50,239 --> 00:49:54,120 Speaker 1: the emotional problems, about their emotional problems and insecurities. So 864 00:49:54,320 --> 00:49:59,040 Speaker 1: we're essentially talking about the birth of robots psychologists here, um, 865 00:49:59,040 --> 00:50:03,080 Speaker 1: which which I I believe the movie Moon explored. We 866 00:50:03,160 --> 00:50:06,919 Speaker 1: had to Kevin Spacey voiced psychologist robot the regularly checks 867 00:50:06,920 --> 00:50:09,480 Speaker 1: in with our main character to uh, to see how 868 00:50:09,520 --> 00:50:13,160 Speaker 1: he's coping with this isolation. Yeah, it was fun. It 869 00:50:13,239 --> 00:50:15,959 Speaker 1: had a number of cool science topics, the Helium three 870 00:50:16,120 --> 00:50:19,000 Speaker 1: isolation and a few others. I don't want to spoil, 871 00:50:19,600 --> 00:50:23,120 Speaker 1: but uh, there's also a two thousand eight study that 872 00:50:23,200 --> 00:50:26,560 Speaker 1: was conducted at the NHC Healthcare in Maryland Heights of Missouri, 873 00:50:26,840 --> 00:50:31,080 Speaker 1: and they found that the robotic dog Abbo or abbo 874 00:50:31,200 --> 00:50:35,040 Speaker 1: ibo ibo a I b o that's the one. Yeah 875 00:50:35,280 --> 00:50:38,520 Speaker 1: he uh he that that particular robot he she whatever 876 00:50:38,719 --> 00:50:41,920 Speaker 1: was just as effective at decreasing human loneliness as a living, 877 00:50:42,000 --> 00:50:48,360 Speaker 1: breathing dog. That's kind of weirdly depressing but comforting because 878 00:50:49,200 --> 00:50:51,239 Speaker 1: we probably don't want to send a dog on one 879 00:50:51,239 --> 00:50:53,280 Speaker 1: of these journeys. God knows it's it's gonna be difficult 880 00:50:53,320 --> 00:50:55,200 Speaker 1: enough to send a human. But if you have a 881 00:50:55,280 --> 00:50:58,480 Speaker 1: robot psychologist, a robot friend all wrapped up into one, 882 00:50:58,480 --> 00:51:02,000 Speaker 1: maybe it's a robot dogs I cologist that can help 883 00:51:02,160 --> 00:51:05,440 Speaker 1: mitigate the problems. Um. Yeah, I guess if he took 884 00:51:05,440 --> 00:51:07,680 Speaker 1: a real dog to Mars, you'd have a big problem 885 00:51:07,680 --> 00:51:10,280 Speaker 1: with like taking it out to do its business. Yeah, 886 00:51:10,320 --> 00:51:12,480 Speaker 1: I mean in the dust. I've been watching a lot 887 00:51:12,520 --> 00:51:17,760 Speaker 1: of shows recently that have a robotic humanoids in it. Um, 888 00:51:17,800 --> 00:51:21,080 Speaker 1: the excellent Humans show that's been airing on and you 889 00:51:21,160 --> 00:51:22,880 Speaker 1: can tell me about that. I've got to check it out. 890 00:51:23,080 --> 00:51:26,319 Speaker 1: It's pretty good. Um. It makes me think, like what 891 00:51:26,360 --> 00:51:28,560 Speaker 1: you need to do is you need a robot family 892 00:51:28,719 --> 00:51:32,920 Speaker 1: to send this uh the space uh explorer with right. 893 00:51:33,680 --> 00:51:35,800 Speaker 1: You can't send him with his actual hit him or 894 00:51:35,840 --> 00:51:38,520 Speaker 1: her with her actual family. You know. Another way you 895 00:51:38,520 --> 00:51:40,040 Speaker 1: could go is if you want to go down the 896 00:51:40,080 --> 00:51:43,480 Speaker 1: total recall route, the Quato route, and then you could 897 00:51:43,560 --> 00:51:47,080 Speaker 1: have a friendly companion in your body with you, like 898 00:51:47,400 --> 00:51:51,080 Speaker 1: Quato's Uh, well you have Big Marshall Bell and then 899 00:51:51,080 --> 00:51:54,480 Speaker 1: he has Quato in his stomach. Yeah, okay, well well 900 00:51:54,560 --> 00:51:57,319 Speaker 1: you know, and maybe the the the form that could 901 00:51:57,320 --> 00:52:01,560 Speaker 1: take is that essentially the I on your ship or 902 00:52:01,600 --> 00:52:04,120 Speaker 1: in your suit, like that is your buddy. Like your 903 00:52:04,160 --> 00:52:05,840 Speaker 1: suit is your buddy. You talk to your suit, and 904 00:52:05,880 --> 00:52:09,360 Speaker 1: your suit is analyzing your your your your your levels 905 00:52:09,360 --> 00:52:12,880 Speaker 1: and your your your current state of physical fitness, and 906 00:52:12,880 --> 00:52:15,440 Speaker 1: then also quizzing you about your mental health. So it's 907 00:52:15,440 --> 00:52:20,279 Speaker 1: like David Hasselhoff in his car. What's the car called, um, 908 00:52:20,480 --> 00:52:23,600 Speaker 1: smart car? Smart cars? No, I don't think it's not 909 00:52:23,680 --> 00:52:29,280 Speaker 1: how kit kits the tea, Yeah, because you need somebody 910 00:52:29,320 --> 00:52:32,880 Speaker 1: to talk to, so talk to the computer anyway. It's 911 00:52:32,920 --> 00:52:35,879 Speaker 1: you know, it's not a perfect, perfect answer. Well, but 912 00:52:36,120 --> 00:52:37,879 Speaker 1: but it's the one we've been looking at. Tying back 913 00:52:37,920 --> 00:52:40,560 Speaker 1: into our echo Boorgs podcast. I think we would need 914 00:52:40,600 --> 00:52:43,640 Speaker 1: better chat pots before this would make any sense. Otherwise 915 00:52:43,640 --> 00:52:45,600 Speaker 1: you're just gonna be up there and infuriated that it 916 00:52:45,680 --> 00:52:48,080 Speaker 1: won't stop bringing up fruit trees. Yeah. I mean it 917 00:52:48,120 --> 00:52:51,200 Speaker 1: comes back to the reminding you of the fruits you 918 00:52:51,239 --> 00:52:53,799 Speaker 1: can't get. Yeah. I mean it comes back to the 919 00:52:53,840 --> 00:52:56,839 Speaker 1: idea that there there's certain things that we've evolved as 920 00:52:56,920 --> 00:52:58,640 Speaker 1: part of our lot to deal with as part of 921 00:52:58,640 --> 00:53:04,360 Speaker 1: our lives, and would be dealing with long term um 922 00:53:04,560 --> 00:53:07,960 Speaker 1: extraction from that environment, and so what can we do 923 00:53:08,160 --> 00:53:13,080 Speaker 1: to mitigate the effects of removal from that environment? Uh, 924 00:53:13,120 --> 00:53:18,000 Speaker 1: and or the recreation of that environment on another planet 925 00:53:18,040 --> 00:53:21,480 Speaker 1: and during the voyage to that planet. Yeah, So is 926 00:53:21,520 --> 00:53:25,160 Speaker 1: your solution to try to simulate Earth on Mars or 927 00:53:25,239 --> 00:53:30,160 Speaker 1: to try to recognize that your Mars habitat isn't Earth 928 00:53:30,239 --> 00:53:34,840 Speaker 1: and deal with the problems as they arise. I know 929 00:53:34,920 --> 00:53:36,360 Speaker 1: that's a tough one. I mean, maybe you try and 930 00:53:36,360 --> 00:53:43,000 Speaker 1: find some sort of space between I'm reminded of one 931 00:53:43,000 --> 00:53:45,440 Speaker 1: of the elements from Philip K. Dicks The Streets the 932 00:53:45,440 --> 00:53:49,799 Speaker 1: Three Stigmata of Palmer Eldrick. Um, they're they're they want 933 00:53:49,800 --> 00:53:51,680 Speaker 1: to read it just based on that title. Oh yeah, 934 00:53:51,680 --> 00:53:53,080 Speaker 1: I mean it's a wonderful book. It's one of his 935 00:53:53,160 --> 00:53:56,040 Speaker 1: trippier books and and really one of his best in 936 00:53:56,080 --> 00:53:59,840 Speaker 1: my opinion. But you have these individuals in space and 937 00:54:00,400 --> 00:54:04,160 Speaker 1: they take this drug called can D which allows them 938 00:54:04,280 --> 00:54:08,600 Speaker 1: to share the experiences of these perky pat layouts that 939 00:54:08,680 --> 00:54:11,000 Speaker 1: they play around, which is essentially kind of like Barbie 940 00:54:11,080 --> 00:54:15,000 Speaker 1: play uh houses with little dolls. Um. But it also 941 00:54:15,080 --> 00:54:18,000 Speaker 1: reminds me a lot of the computer game The Sims. 942 00:54:18,800 --> 00:54:20,799 Speaker 1: You know, You're really end up. I haven't played it 943 00:54:20,840 --> 00:54:22,520 Speaker 1: in you know, over a decade, but I remember when 944 00:54:22,560 --> 00:54:24,920 Speaker 1: it came out and I'm playing it, remember how invested 945 00:54:25,320 --> 00:54:28,239 Speaker 1: I felt in these uh these little you know, non 946 00:54:28,280 --> 00:54:33,240 Speaker 1: existing characters and they're little, very you know, one dimensional lives. 947 00:54:33,840 --> 00:54:36,560 Speaker 1: But but it reminded me even then a lot of 948 00:54:36,560 --> 00:54:40,000 Speaker 1: of perky pat and and of course the in this scenario, 949 00:54:40,200 --> 00:54:45,040 Speaker 1: there's a there's a pharmaceutical, uh means of of increasing 950 00:54:45,200 --> 00:54:47,919 Speaker 1: your involvement with perkey Pats. So I don't know, maybe 951 00:54:47,960 --> 00:54:51,480 Speaker 1: it's a situation of giving the the astronaut or robotic 952 00:54:51,560 --> 00:54:55,080 Speaker 1: family that looks after him and analyzes his, uh his 953 00:54:55,080 --> 00:54:58,760 Speaker 1: mental state and then also secretly, you know, pumping ecstasy 954 00:54:58,760 --> 00:55:02,640 Speaker 1: and in the whole trip. Maybe that's the the answer. 955 00:55:02,800 --> 00:55:05,359 Speaker 1: That's what I'm suggesting. We're gonna have to be way 956 00:55:05,440 --> 00:55:08,120 Speaker 1: less prude issue about our methods to keep the astronauts 957 00:55:08,160 --> 00:55:10,200 Speaker 1: truly happy. Yeah, you kind of end up having to 958 00:55:10,480 --> 00:55:14,960 Speaker 1: perhaps take that that lab rat mentality. Right, This is 959 00:55:15,800 --> 00:55:19,480 Speaker 1: maybe less a person in more an experiment. This is 960 00:55:19,480 --> 00:55:22,080 Speaker 1: more about the living cargo, and how do we keep 961 00:55:22,120 --> 00:55:26,200 Speaker 1: the cargo uh in in shape for the duration? Yeah, 962 00:55:26,200 --> 00:55:30,920 Speaker 1: that is an interesting question. How how mercenary do you 963 00:55:30,960 --> 00:55:34,560 Speaker 1: want to be about keeping the astronauts on your Mars 964 00:55:34,600 --> 00:55:38,080 Speaker 1: colony happy? Like if you found that you could just 965 00:55:38,200 --> 00:55:41,759 Speaker 1: give them a drug that would make them, you know, 966 00:55:41,920 --> 00:55:44,680 Speaker 1: sort of placated, and then the oldest Huxley sense to 967 00:55:44,719 --> 00:55:46,719 Speaker 1: go back to that, you know, if you could, if 968 00:55:46,760 --> 00:55:49,440 Speaker 1: you could make a brave new world on Mars, and 969 00:55:49,440 --> 00:55:51,600 Speaker 1: and that was a pretty reliable way to keep the 970 00:55:51,640 --> 00:55:55,719 Speaker 1: astronauts from going crazy, would you do it? Yeah? I mean, 971 00:55:55,760 --> 00:55:59,640 Speaker 1: and it also just drives home that we don't belong there, 972 00:56:00,120 --> 00:56:03,520 Speaker 1: right in a very very basic sense, like this is 973 00:56:03,560 --> 00:56:07,600 Speaker 1: not our world. And it's it's not how it's completely 974 00:56:07,600 --> 00:56:11,759 Speaker 1: inhospitable to the human form. We want to go there. 975 00:56:11,840 --> 00:56:13,960 Speaker 1: We want to go there to two so we can say, hey, 976 00:56:14,000 --> 00:56:17,120 Speaker 1: we have been to Mars, and then in our grander 977 00:56:17,600 --> 00:56:21,720 Speaker 1: visions of the thing, we want to recreate Earth life there. 978 00:56:22,400 --> 00:56:26,200 Speaker 1: But is that is that just kind of a ridiculous 979 00:56:26,239 --> 00:56:29,160 Speaker 1: notion that we eventually have to get past. Yeah? I 980 00:56:29,160 --> 00:56:32,719 Speaker 1: don't know. Is it wishful thinking? I don't want to 981 00:56:32,760 --> 00:56:34,960 Speaker 1: take away from this episode to be let's not go 982 00:56:35,040 --> 00:56:37,839 Speaker 1: to Mars, right, I mean, because I don't feel that way. 983 00:56:37,880 --> 00:56:40,959 Speaker 1: I'm in a lot of ways I support a very 984 00:56:41,000 --> 00:56:46,239 Speaker 1: aggressive program of space exploration and colonization. But I think 985 00:56:46,280 --> 00:56:49,440 Speaker 1: we're just highlighting how difficult this project is if we 986 00:56:49,480 --> 00:56:51,839 Speaker 1: want to do it right, all of the things we 987 00:56:51,880 --> 00:56:53,600 Speaker 1: have to learn and all the things we don't we're 988 00:56:53,640 --> 00:56:56,360 Speaker 1: not even aware that we don't know about the dangers 989 00:56:56,400 --> 00:56:59,399 Speaker 1: of space and Mars and and and colonization of other 990 00:56:59,440 --> 00:57:04,120 Speaker 1: bodies in the Solar System. Indeed, the destination is hostile, 991 00:57:04,360 --> 00:57:08,400 Speaker 1: the trip is dangerous and lonely, and those are realities 992 00:57:08,440 --> 00:57:10,640 Speaker 1: we have to face if we are actually going to 993 00:57:10,680 --> 00:57:13,080 Speaker 1: send humans to Mars. Yeah, but if you're one of 994 00:57:13,120 --> 00:57:16,400 Speaker 1: those people out there who's working on these problems. Right now, 995 00:57:16,520 --> 00:57:18,880 Speaker 1: I salute you and I and I say more people 996 00:57:18,920 --> 00:57:23,440 Speaker 1: should support your efforts. Indeed, yeah, I'm still one behind 997 00:57:24,440 --> 00:57:27,040 Speaker 1: putting up you know, human on Mars. Uh you know, 998 00:57:27,280 --> 00:57:29,240 Speaker 1: just one though, just just one. Yeah, I don't think 999 00:57:29,240 --> 00:57:33,120 Speaker 1: we should go crazy, just just one. Really, it should 1000 00:57:33,160 --> 00:57:36,080 Speaker 1: just be Val Kilmer, just Valkolmer. Or who's going to 1001 00:57:36,120 --> 00:57:39,360 Speaker 1: be in the upcoming film about the I think it's 1002 00:57:39,400 --> 00:57:42,400 Speaker 1: Matt Damon. There's a film. Yeah, I heard about that. 1003 00:57:42,480 --> 00:57:45,760 Speaker 1: I haven't read that book, but I hear good things interesting. 1004 00:57:45,880 --> 00:57:48,800 Speaker 1: So we'll have to we'll have to revisit this topic 1005 00:57:48,800 --> 00:57:51,520 Speaker 1: when that film comes out.
