    The transcript for this episode is below.

    This… is Making New Worlds

    It’s been five years since Making New Worlds ended, so if you’re listening to this episode because you were still subscribed to the podcast… thanks for being such a loyal listener! Or maybe just one who doesn’t tidy up their podcast subscriptions.

    I’m recording this bonus episode to update you on some recent Making New Worlds-related projects that you may be interested in

    First of all, I’m very excited to announce that I have a book coming out on March 7 called Off-Earth: Ethical Questions and Quandaries for Living in Outer Space. The book is essentially an expansion of the Making New Worlds podcast: it includes some of the content from this podcast, plus a bunch of new research and interviews I’ve done since the podcast came out.

    Basically, if you enjoyed Making New Worlds and just wish there was more of it, you’ll like Off-Earth!

    You can pre-order Off-Earth now at any of the major online booksellers. I’ll also put a link in the show notes, along with a preorder discount code you can use if you order through Penguin Random House.

    If a 13-episode podcast and an entire book aren’t good enough for you, I also have a free weekly newsletter, also called Making New Worlds, where I write about various topics and recent news stories related to ethics and human space settlement. You can find the Making New Worlds newsletter on Substack.

    And finally, just after the podcast wrapped up in 2018, I realized I wanted to do more than just talk and write about how to create better futures in space and on Earth, I also wanted to actively work towards those futures. So along with another astronomer, Lucianne Walkowicz, I co-founded a non-profit organization called the JustSpace Alliance. Our mission is to advocate for a more inclusive and ethical future in space, and to harness visions of tomorrow for a more just and equitable world today. If you’d like to learn more or become a member, you can visit our website at justspacealliance.org.

    And that’s what I’ve been up to in the past five years! Thanks again for listening— all the projects I just described grew out of this podcast, which exists because of interest from listeners like you. You can still listen to any of the past episodes, or read the transcripts, at makingnewworlds.com.

    This has been Making New Worlds, a podcast by me, Erika Nesvold. Our intro and outtro music is by Herr Doktor.


    Ep 13: Should We Settle Space? Feb 28, 2018
    Show notes

    For the last episode of Making New Worlds, we ask the question we skipped at the very beginning: Should we settle space? Featuring answers by many of our guests from previous episodes. The transcript for this episode is below. Imagine this: You live on Earth, in 2018, still the early decades of the space age. It feels like humanity is standing at a crossroads: We’re beginning to face the ramifications of the damage we’re doing to the planet, while at the same time we’re starting to talk seriously about creating settlements on other worlds. But there are so many challenges facing us here on Earth, and developing the technologies and infrastructure we’ll need in space will require a huge amount of effort and resources. So… should we settle space? Welcome to the final episode of Making New Worlds, a podcast about the ethical issues involved with settling space. I’m Erika Nesvold. In the first episode of this podcast, I said that we’d be skipping over the question of whether we should settle space. I asked my guests and listeners to assume that space settlement was inevitable, and to think about *how* we should go about doing it. But now that we’ve reached the last of our planned thirteen episodes, let’s revisit this first, fundamental question. I interviewed 28 fantastic guests for the podcast, and at the end of each conversation, I asked them the same question: Do you think that we should settle space? I got a really interesting range of answers, especially when you consider that the sample of people that I polled was limited to people who agreed to be on a podcast about space settlement. Unsurprisingly, I got a lot of very enthusiastic “yes”s. Michael Waltemathe: “Yes! Yes, I do. I definitely think we should settle space.” Laura Montgomery: “Oh, yes. Oh, yes.” Kelly Smith: “Oh, yes. Oh, yes.” Shawna Pandya: “Oh, absolutely. There’s so many reasons.” That was Michael Waltemathe, Laura Montgomery, Kelly Smith, and Shawna Pandya. The reasons that my guests gave for these “yes” votes reflected a lot of the motivations we talked about in Episode 1. For example, the idea that we need to spread our civilization to multiple planets in order to prevent extinction. Here’s Michelle Hanlon. Michelle Hanlon: “Absolutely. I think it is incumbent on us to settle space for our own survival. I absolutely believe Stephen Hawking that whether we put ourselves into untenable position through nuclear fallout, whether it’s natural disasters, there’s a cycle in evolution, species die out, and if we want to continue as a species, we need to get off this Earth… We have the technology, we have the innovation, we have the brains, incredible minds right now working to get us back to the Moon with companies like Astrobotic and Part Time Scientists. There’s no reason not to harness that and get us out there and explore the Moon, Mars, and deep space.” Shawna Pandya made a similar argument, one that I hear a lot in the space industry these days. Shawna Pandya: “If we can successfully settle off-world, we’re no longer putting all our eggs, or in this case all our humans, in one basket. And there’s this facetious saying that I’m sure you’ve heard in the space industry, that the dinosaurs didn’t have a space program, and look how far it got them.” But my guests also talked about other reasons for settling space, reasons that don’t have to do the with survival of the species. Here’s Brian Ferguson. Brian Ferguson: “I think it’s a great aspiration. I think it’s something that could provide a unifying force for humanity. I mean, look, after all, at the space station today. Russians and Americans are not getting along very well right now, but they are in space. And this is something that could be developed as a principle. I know there’s going to be more opportunities to militarize space but to work towards a space exploration that is not done on a national basis, but is done on a human basis, that includes people from all over the world, that could be a kind of a model for people back home and going forward in time, could eliminate some of the possible divisions that would ensue if it’s a nation-based colonization program.” Kelly Smith brought up Manifest Destiny in his answer, an idea we discussed critically in Episode 1, but he also mentioned the idea that by moving our civilization off-world, we’ll actually make the Earth a better place for other species to live. Kelly Smith: “I sometimes annoy some of my colleagues by being one of those guys that really believes in something akin to Manifest Destiny. I think if you really think long-term about the future of humankind, it clearly lies in space. Absolutely clearly. And that’s true even if you’re an environmentalist and you only care about stuff on Earth. It doesn’t seem like it, but you know, one of the arguments that people, I think, can make more of is they can say, “If you’re interested in preserving all the resources and biodiversity on Earth, then you have an interest in making sure that we don’t have strong incentives to dig stuff up and burn things down on Earth.” Well, we could go back to being Amish. Right? We could all live in the 19th century. But if we want a technological civilization like we have, we have to have a place to get those resources. And guess what? The Solar System is chock full of them. So you should really, in the long run, you should be in favor of trying to find ways to get what humankind needs from space.” Some of my other guests were generally in favor of space exploration and settlement, but were a little more cautious. Lauren Benton and Keith Abney both pointed out that you can explore space a lot more efficiently and safely with robots than with human explorers. Here’s how Lauren Benton put it. Lauren Benton: “I have learned very clearly from my scientist friends that they can very often do just as much space– just as much science remotely without human beings present, and maybe more than they can with human beings aboard. But at the same time, I think historically there is a lot of evidence that, you know, human beings like to be there, like to be witnesses, like to see themselves there. In fact, I would say that in the history of writing about colonization, the first-person testimony and the first-person witnessing reports were extremely important in circulating information about colonies. And I imagine that will continue to be the case, and could be the case in the future of space. So, I suspect there’s always gonna be an impulse for human beings to be there, even if there isn’t a scientific reason for them to be there.” James Schwartz also made an argument for prioritizing science and exploration over settlement, at least for now. James Schwartz: “We need to settle space over the long term. But over the short term, I think there are more pressing things to do, both here and in space. In particular, I think scientific research is the main thing that needs to occur in various places in the Solar System. And settlement can facilitate that in some ways but it can also get in the way because it’s a competition for resources. So I think in advance of any, you know, major settlement endeavor, we need to have good science done at various locations, in various places.” Donna Gabaccia is a fan of space exploration, but is worried about the path we might go down if we shift our goal to colonization. Donna Gabaccia: “Humans always rise to the occasion, they’re always curious. And, you know, that’s the part of exploration, in particular, that I still would encourage and support. Once we start to use the word colonization, however, I’m less sure that that should be our goal. It may very well be, some time in the very distant future, that we will encounter habitable (by human) empty spaces, but it may equally be possible that we will only find those habitable spaces to be inhabited by someone else. And both in sci-fi and historically, those have not usually ended well. They have generated inequality, they have generated massive death, and they have generated wars between worlds. So, when I think about colonization, I’m not so sure that’s a goal that should be pursued independent of, you know, let’s explore and see if there’s someone out there. I would actually think many times about that, because I believe humans frequently have made a mess of their own lives on this planet and I frankly would hate to see that exploited elsewhere. Sorry to be so grim.” Some guests were skeptical of our ability to settle space, even with future technologies, given the enormous challenges. For example, here’s Mehmet Ozalp. Mehmet Ozalp: “I certainly think we should try. We should try to look for ways, develop technologies that would take us beyond the Moon, to Mars, and beyond the places to Mars. And some pioneers may risk their lives in the process. It’s all part of that human curiosity and wanting to stretch the boundaries. I’m certainly for that. But I’m not sure if it will at all be possible to have a reasonable settlement in outer space, before we destroy the Earth itself. You know, like, we could run out of time. I don’t know, I’m not a futurist, but it doesn’t– I can’t see that we could do it in a reasonable timeframe and then still have a sustainable life on Earth.” Other guests said yes, maybe someday, we should expand out into the universe. But right now? We’re just not ready. Here’s Karen Backe. Karen Backe: “My hesitation is fundamentally ethical, I don’t think that humans are grown-up enough as a species to be responsible in exploration. I think that all of the Earth-bound incidences we have of human civilizations coming into contact with new places and other civilizations, we’ve seen a lot of exploitation that would be pretty tragic to repeat anywhere. But I don’t know, I guess I’m fundamentally an optimist, and I think that children never grow up unless they’re given the opportunity to take bigger challenges. And that there’s really a possibility that when presented with larger challenges that we might rise up to a new level of capacity, of being. And that would be pretty great.” Several guests said we need more information, more data, about what it will take for us to live in space. For example, here’s Rebecca Kukla. Rebecca Kukla: “ I’m not sure I have a yes-or-no answer to the question of whether we should settle space. I think that I would need a lot more empirical knowledge than I think even exists or certainly than I have about exactly the kinds of risks that you’re talking about. And also, I would want to know a lot more about how much is gonna be done in advance to make sure that by the time that colony starts, it has the kinds of social support institutions and legal institutions and so forth that we have here on Earth that I think are incredibly important protections for allowing people to lead flourishing lives.” Some of the guests who said no, we shouldn’t settle space, pointed to an idea that’s come up in a few of these responses: that space settlement will just mean that humans will export all of the problems we have here on Earth into space. Here’s Sarah Newell. Sarah Newell: “But generally, I’m gonna go, “No,” on settling space, because I think human beings are not to be trusted with colonization based on our past efforts. I think it will be another place for us to environmentally destroy and abuse workers.” Others argued that the time and effort we would spend on settling space could instead be used for solving problems on Earth. For example, here’s Darcie Little Badger. Darcie Little Badger: “One issue I have is that a lot of these resources that are being expended towards these vastly expensive projects that probably aren’t feasible within the near future could be instead used to help improve our prospects here on this planet. I do think that it is worth thinking about, but I do wish that maybe more of those resources could be instead funneled into Earth-improvement-based projects. Unfortunately, as a climate change scientist I am aware that some pretty serious changes are coming, not just with sea level change, or with drought. For example, I studied a toxic-producing phytoplankton, and blooms of these plankton are becoming more frequent. So, we’re having all these issues on Earth, and right now it is really the only place where we and our beautiful ecosystem can thrive. Although, I don’t— I’m not against settlement in space, you know, as a broad blanket statement, I do wish that more of this attention can be placed on improving the Earth right now.” Zuleyka Zevallos made a similar point. Zuleyka Zevallos: “There are no ethical justifications for settling other planets. What we need to do is focus on repairing the damage in our own planet, and taking greater responsibility for the way in which we plan future scientific endeavors on Earth, and how we can use science and other bodies of knowledge from Indigenous groups, from other people of color, from communities of color, bring them all together in order to make a more viable and sustainable future on our planet.” A lot of my guests agreed with me that space settlement seems inevitable, so maybe we should be focusing on how best to do it. Here’s Michelle Brown. Michelle Brown: “Because I’m sociological by training, I often– And maybe this is a way to evade your question– I don’t get into the “shoulds” as much as I think we will settle space. I think that’s, you know, I think that’s already– There’s enough indications that those sorts of things are already happening. I think in a world in which we have market economies and capitalism, space settlement will happen. So I’m much more concerned with the idea about what it would mean to have active democratic voices involved in what the actual shape of that existence would be and how we could do exactly the kinds of things you’re pointing to.” Even these responses came with both optimistic and pessimistic perspectives. For instance, here’s Jesse Shanahan, with a glass that’s half-full. Jesse Shanahan: “Because in so many ways, it’s a blank slate. We can choose what we take with us into space. And so, as much as possible, the people doing this need to be very progressive, and they need to be very well aware of existing social and ethical problems on Earth. Because we don’t want to take the problems on Earth and just copy-and-paste them into space.” And here’s Debbie Becher, with a half-empty glass. Debbie Becher: “I think as a sociologist, what I would want to point out is that space isn’t a blank slate. We are here already, as a world, highly institutionalized. That is, if we settle space we are bringing all of that with us. And it’s not just lessons, we’re actually bringing the institutions, the organizations, the governments, the corporations, our cultures, all of that will be involved in settling space. It’s not a matter of, we can just decide to pick and choose what we like from it and then, and take only the stuff we like over there. I mean, that’s what we’re seeing in this political and corporate fight for resources in space already, right? Only those who are powerful enough or scientific enough, or interested enough are getting involved in the first place. And they’re gonna wield those powers as they fight for it.” I’m an optimist, by nature. So while I think space settlement might be inevitable, and while I’ve certainly become more convinced of humanity’s ability to screw it up in the course of making this podcast, I also think that we can prevent the darkest possibilities for our future in space by taking the time to think about the kinds of worlds we want to create. And there is so much we can learn from people like my guests, about how to learn from our past and present to work for a better future. Michael Oman-Reagan: “They are going to settle space whether we like it or not, so we, especially people who are opposed or skeptical, or have critiques, or are excited about it but have visions that include justice, we need to engage with…

    Ep 12: What Do You Think? Feb 21, 2018
    Show notes

    What do you think about the space settlement ethics topics we’ve covered in the podcast so far? This episode includes comments and feedback from members of the Making New Worlds audience.

    The transcript for this episode is below.

    Welcome to Making New Worlds. I’m Erika Nesvold. For the past eleven episodes, I’ve been talking to various experts about the kinds of ethical challenges we might face as we move our civilization into space. But as we’ve heard multiple times on the podcast, space is for everyone, not just the experts and industry leaders. So I asked my listeners and followers for their thoughts on the topics we’ve covered so far. Before I get into the results, I just want to point out that you shouldn’t read too much into the statistics of the responses I got. The polls I conducted on Twitter were extremely unscientific, skewed heavily towards other astronomers and space enthusiasts. But I got some really great answers, and I appreciate everyone who responded.

    Let’s start back at the beginning, with Episode 1, where we talked about our motivations for going to space. I ran a Twitter poll asking what our primary motivation should be, and provided three options: one, as a backup to the Earth, in case humanity needs a new home someday; two, as more room for a growing population; and three, because it’s “humanity’s destiny”. That last one was the most popular answer, getting 44% of the votes. There were also some pretty poetic responses pointing out that humankind has a need to explore and expand that goes beyond just survival. A Twitter user by the name @TheClarksTale argued that “People need a frontier… to explore, and have an option to live outside the social confines of most of humanity.” As Twitter user @landingpartyof1 put it, “As far as we know human life remains meaningless. Assuming there is some sort of meaning to be had we aren’t going to find it sitting here. Thus, to space and beyond.”

    But there were also some arguments for space as a way to protect not just our species, but the other species on Earth, either by preserving them in space in the event of a catastrophe, or by leaving them a cleaner, less crowded Earth while we go off to explore the stars. As my colleague Eric Dahlstrom put it, we should go to space to “‘green the asteroids’ into a solar system of biodiversity. (Humans are just tools for plants to explore space.)” he said.

    And Jeffrey Montes said on Twitter, “These days I think often of the Earth and how precious and unique it is. Space is hopeful in that it might provide the only lasting way to protect Earth.” On our Facebook page, Joshua Rosenthal argued that the lessons we would learn by expanding into space and terraforming other planets could help us reverse some of the damage we’ve caused on Earth. He said, “If we have the technology to terraform otherwise uninhabitable planets making them habitable and earth-like, why would we not apply that same technology to fixing earth? I would argue that our society tends to seek solutions to problems and in this example could build other worlds, but would probably also actively repair our current one with that same technology. This would be practical and economical as well as moral.”

    The next question I asked my followers came from Episode 2, which was about how we select who gets to go and settle space. Of the three options I offered in my poll, hardly anyone picked the first option, “whoever can afford the ticket.” The responses were roughly evenly split between the other two answers: either the space agency or corporation like SpaceX should select their passengers, or “whoever wants to should get to go.” You might remember that this last option was suggested by one of my guests for Episode 2, Michael Oman-Reagan, who argued that until we’ve reached the point that anyone who wants to can go live in space, we’re not ready to settle space as a species at all.

    A few people suggested a fourth option: some kind of lottery system, or maybe a combination of a rigorous selection for some spots but a lottery for others. I actually really like this idea, myself. There was a lot of discussion about how people should be selected for a spot in the settlement. Physical fitness came up a lot, which made me think back to my guest Jesse Shanahan’s comment that even if you send the absolute healthiest, most able-bodied people to live in space, eventually, as generations pass, you’ll have disabled people living in space, too. So maybe the better choice is to plan to make space as accessible as possible.

    People also talked about the non-physical qualities that would be required for selection as a space settler. On our Facebook page, Nick Krewson envisioned selection based on expertise, in several stages. He said, “First, engineers and biologists to build a basic, sustainable infrastructure. Next scientists and resource support personnel to build on that infrastructure. Finally, poets, dog walkers, and IT Directors?”

    But on Twitter, the conversation centered around temperament. Harshita Gupta said we should send “People most likely to survive there AND not start a war on the planet. Basically really smart people.” And user @EliteYacob suggested “Extensive testing to determine individual personality traits and goals. Willingness to work and cooperate is important too. Selfishness and self centered personalities would lead to the same problems we have here. Also can’t have people who can’t accept being wrong. Hubris sucks.”

    I think there are a few problems with screening people based on personality, although psychological testing is part of the NASA astronaut selection process now. For one thing, while we have some idea of what kind of temperament performs well in a dangerous, mission-based environment like space, I’m not sure we know as much about what kind of person would do well building a new community far from home. We can’t even agree on what a community should look like: how it should be structured and run, how it should interact with other communities. Not to mention, you probably need lots of different personality types to form a strong community.

    Let’s move on to my next poll, which came from Episode 3, on property rights. I asked my followers to imagine living in a space settlement, then asked: “Who owns the land you’re living on?” This one was a landslide: 70% of the responses said it should be communal property, while only 20% imagined that they would have bought the land they lived on in space. User @landingpartyof1 suggested private ownership, but in a system where the land is distributed to owners, not bought: “Original settlers get X amount of personal space with governmental provisions to update policy as more and more arrive.”

    Speaking of money, my question from Episode 4 had to do with economics: How do you acquire goods and services in a space environment? This answer surprised me a bit, although it shouldn’t have after the property rights poll. 50% of voters said “Everything should be shared”, while 27% voted for a barter system, and only 9% went with a capitalist system.

    A few people pointed out that the answer depended on things like the size and age of the space settlement in question. David Wilson pointed out “there may be different answers for settlements just starting out with very limited resources, thriving self-sufficient settlements, and those somewhere in between.” And Joseph A’Hearn said “For a small enough settlement, people can share everything, but I don’t think it would work for groups of, say, over 5,000 people.”

    One of my listeners from Ireland, Connor Hogan, reached out on Facebook to send me a link to his undergrad thesis on ethics in space exploration, titled, “Private Production and the Future of Human Space Exploration beyond Low Earth Orbit: A Practical and Ethical Critique”. In it, Connor talks about the challenges of labor rights in a capitalist space economy. He suggests that “we need a new approach that emphasises communal ownership (i.e. “whoever lives on the spaceship owns the spaceship”, or has a stake as it were), and a global forum/think-tank to approach these issues democratically with this in mind.”

    Episode 5 was about crime and punishment in space. When I asked what a space settlement should do with a citizen who’s broken the law, only 10% of people chose “prison”. As my colleague J.L. Galache put it, “Space prison is a luxury we can’t afford in early space settlements. It also doesn’t work especially well on Earth, so we should learn from experience, no?”

    The other options I offered were more popular. 24% of voters selected “send the person back to Earth,” while 43% chose “loss of privileges”. User @cdkharris suggested “Restorative justice + loss of privilege for repeats. If theft or destruction of resources, how can they be repaired or replaced? If someone was hurt, how can they be made whole?” I really liked this answer, and it reminded me of the great discussion I had with my guests in Episode 5 about transformative justice.

    My next poll was a yes-or-no question, from Episode 6: Do you think war in space is inevitable? The votes were exactly split down the middle. And the responses pointed out that this question can be asked about our future in general, not just in space. As Laura Montgomery put it, “I don’t think space will magically make us better people, so if someone figures a need and a method, there could be war.”

    Listener Kyle Foster also wrote in via email about Episode 6. Remember that one of the things my guests discussed in this episode was the possibility that international conflicts here on Earth could extend outwards to include those nations’ settlements in space. Kyle pointed to two contrasting examples of this scenario in classic science fiction: Ray Bradbury’s The Martian Chronicles, in which, as Kyle puts it, Mars colonists “return to Earth upon the occasion of a colossal war.” On the other hand, in the movie adaptation of Arthur C. Clarke’s “2010”, the threat of war on Earth briefly divides the protagonists, but eventually they buck orders and rejoin forces. Kyle wrote that the reaction of the characters in “2010” felt more plausible to him, and asked “to what extent would conflict on a home planet actually induce conflict in a colony? Is the leash really that long, that taut?”

    Episode 7 was all about reproductive rights and challenges in space. I asked my Twitter followers how they thought a space settlement with limited resources should control its population size. 40% of voters said the settlement shouldn’t attempt any official population control, while 30% favored some kind of limit in the number of children allowed for each adult, and 10% chose a lottery for having kids.

    Episode 8 was on terraforming and conservation. I asked whether we should be concerned with environmental conservation as we move out into space, assuming that we don’t find any life there. 58% of the voters said we should preserve historical sites, so I’ll just point out to those voters that For All Moonkind is working to do just that on the Moon. 25% said we should focus primarily on conserving resources, and 17% said we don’t need to worry about conservation in space at all. Here’s how Rand Simberg put it: “We should evaluate and respect the value of certain locations, but in general, rocks don’t have rights. Asteroids are certainly not scenery.”

    Now let’s assume we do find life out there. We talked about planetary protection and astrobiology ethics in Episode 9. I asked my Twitter followers what we should do if we find microbes on Mars. 24% said that in that case, we shouldn’t settle Mars at all. That’s in line with what Carl Sagan said on the topic in his book Cosmos: “If there is life on Mars, I believe we should do nothing with Mars. Mars then belongs to the Martians, even if the Martians are only microbes.” But 59% of the people who responded to my poll said that we should try to carefully cohabitate with these hypothetical Martian microbes. Only 6% said that we shouldn’t worry about the microbes at all.

    The last poll I ran on Twitter came from Episode 10, on medical ethics. I asked how we should triage patients in a resource-limited space settlement. The overwhelming majority of voters selected the triage methods we’re most familiar with in our medical system: prioritizing patients according to their likelihood of survival. I did get a few votes for the other options, prioritizing based on age or based on the patient’s expertise or job in the settlement, but it sounds like the people who responded are most comfortable with the triage protocol used in most hospitals and mass casualty incidents today.

    I also got some great feedback on topics that weren’t covered in the podcast. For example, I received a couple different emails pointing out the challenges of communication as settlements move farther and farther from the Earth. As one email put it, “Can we find enough colonists to sign up and leave the Internet behind forever?”

    Listener Terry Nesvold, AKA my mom, wrote in with another interesting point about the problem of privacy: “Arguably, scientists, as well as the backers of a space colony, whether corporate or government, if not all humankind, have a right to know how the colony is doing, collect data on the health and well-being of the colonists, and particularly learn as much as they can about the colonies that fail. Where does that leave the personal privacy of the colonists and their eventual descendants? Do they just sign that away at the start, as astronauts do? Do they get to draw a line somewhere, before their everyday lives become “the ultimate reality show” for the Earth-bound?”

    I’d like to thank all of our audience members who submitted their comments and thoughts on Making New Worlds. So many of these questions reflect challenges and complexities that we already face here on Earth. I hope we can keep the conversation going.

    Next week, we’ll explore a question that we’ve been avoiding for most of the podcast so far: Should we settle space? Join us next week for the final episode of Making New Worlds.

    How will people of faith adapt their religious practices to the space environment? How will our cultural values help us adapt to life in space? Christian theologian Michael Waltemathe and Muslim theologian Mehmet Ozalp discuss examples of how the limitations of space will affect religious rituals and traditions. And Alaskan Native Alice Glenn describes how her community, the Iñupiat people, have adapted to live in a harsh environment that shares a lot of characteristics with space. The transcript for this episode is below. Imagine this: It’s been a year since you left Earth for your new life in space. The settlement is doing well. Your family has grown, your habitat is expanding, and your community is thriving. You want to acknowledge this one-year milestone with a celebration. But you’re also a person of faith, and want to express your gratitude in a quieter, more personal way, too. What do you do? How much of your culture and religion have you brought here from Earth? How have you adapted your ceremonies and rituals to life in space? How has your culture helped you adapt to life in space? Welcome to Making New Worlds, a podcast about the ethical issues involved with settling space. I’m Erika Nesvold. Today we’re talking about religion and culture. Unlike some of the other topics we’ve covered, this one doesn’t have big, scary ethical questions and implications. But religion and ethics are closely linked for many people, and our culture and values will drive a lot of the choices we make about how to live in space. So I wanted to explore how our rituals, traditions, and values, will shift as we move off-Earth. Let’s start off by asking, how will we need to adapt our religious practices to life in space? People of faith have been traveling to space for decades now, so we already have some real-life examples of this. You might remember Protestant theologian Michael Waltemathe from our episode on planetary protection. He provided a couple of examples of religious activities in space in the Apollo era, both of which involved Christian practices. Religious activities by NASA astronauts has always been a bit controversial, since NASA is a government agency and the United States has laws about the separation of church and state. Michael Waltemathe: “When Apollo 8 flew around– flew to the Moon and back, and they orbited the Moon, they read from biblical scripture on Christmas Eve, 1968, and well, they basically read the story of creation, the first four verses. And then they blessed the population of Earth, and that caused quite a stir, because a couple of days later, the American Atheist Association sued the U.S. government for spending taxpayers money on religious messages from outer space. And the funny thing about that is that that went all the way up to the Supreme Court, and the Supreme Court threw it out because they said they did not have jurisdiction in lunar orbit. Which I think is a fascinating answer to that problem.” So far, there isn’t anything inherent in the environment of space or the Moon that makes it too difficult for astronauts to practice Christianity. Michael Waltemathe: “In the Apollo program, when Neil Armstrong and Buzz Aldrin landed on the Moon, Buzz Aldrin had taken some wine and wafers and a silver chalice, and the first thing they did on the surface of the Moon was, they actually celebrated Holy Communion. So that ritual worked very well in lunar gravity, you could say. Also, there’s some– When you look at the footage of the Apollo missions, there’s astronauts reading biblical texts from the surface of the Moon. I think that is something that was just part of the space program at that time. Christian astronauts had brought their religion with them out there, and they performed their religion and it was part of the mission in that way.” But what about other religions with different practices? In Islam, for example, Muslims are required to pray five times a day. These prayers have a specific format: they should be done in a clean place, and involve standing, bowing, and prostration on the ground, while facing towards the holy city of Mecca. Michael Waltemathe: “When the first Muslim astronaut flew into space, there of course was the question, where do you pray when you’re orbiting the Earth at the speed that the ISS does? So if you have to pray towards a certain direction, which is Mecca in the case of Islam, how do you do that when you’re orbiting the Earth?” I consulted Muslim theologian Mehmet Ozalp about this question. Mehmet Ozalp: “I am the Associate Professor for Islamic Studies at Charles Sturt University, Australia. I’m also the director of Center for Islamic Studies and Civilization, which was established in 2010 in Charles Sturt University. And it is the only university that offers an undergraduate-level Bachelor of Islamic Studies.” Mehmet is very interested in the practice of Islam in the modern world. He told me more about the requirements of daily prayers, and how Muslims adapt them to new environments. Mehmet Ozalp: “For Muslims it’s the– the direction is towards the Kaaba, the building inside Mecca. If someone is, for example, residing in Mecca or is doing pilgrimage, they would have to face in the direction of the Kaaba, the building itself. But scholars have said in the past that if you are outside of the city, it’s sufficient to just turn towards the city of Mecca. I guess you would get it just about right if you do that. Then when you look at the classical Islamic scholarship, they do talk about, what do you do if you’re on a ship and the direction of the ship is changing all the time? And they have come up with solutions to this. And they say that you start off with– facing in the direction of Mecca when that ship is in that direction at that particular time. It does no matter if the ship changes direction. You just keep your direction, it’s out of your control. While others say that if ship changes direction, you also change yourself slightly, if you can, as well, assuming that that can be done. This comes up in airplanes, you know, when someone is flying, what direction you face. Especially when you’re in the Pacific or something where you could go both directions. And then there’s the issue of curvature of the Earth. So all of this comes into play in space, as well. If someone’s in a space station, these are the things that the person has to think about: that the station is moving constantly, and that the direction would change.” When this question came up for a Malaysian astronaut who traveled to the International Space Station in 2007, Malaysia hosted a conference of Islamic scholars to decide on this question and a few others. Malaysia’s National Fatwa Council produced a document that discussed requirements for prayer and fasting for Muslims on the ISS. Here’s Michael Waltemathe again. Michael Waltemathe: “And if you’re off-planet or if you don’t know where you are, then you have to pray to Allah with the will in your heart to pray to Allah and not somebody else. So that is basically the rule that they apply. And the astronaut, Sheikh Muszaphar Shukor, who was on the ISS, he says in an interview, and I think it’s a fabulous quote, he says, “And that’s good, because Allah wants adoration, not acrobatics.”” But there are other aspects of the space environment that can pose a challenge for certain religious rituals. Weightlessness, for instance: how do your prostrate yourself on the ground if you are floating in space? Islam, as Mehmet told me, has a long history of adapting to these kinds of environmental limitations. Mehmet Ozalp: “I think that Islam is a flexible religion, inherently, in its practices. It does take into account difficulties one may face. And even from the time of the Prophet Muhammad, for instance, when Muslims pray, or before praying, they have to have ablution. And what if you don’t have water? What are you going to do? So there’s something called sand-washing, you know, you tap your hands on sand and you kind of wash your limbs. So there’s flexibility. There’s always some sort of a replacement and adjustment that can be done. Because fundamentally, the purpose is to pray. And as the Quran says, God is not in the West, not in the East. God is, kind of, beyond space and time. So the direction is just to indicate, to have a unity of direction and prayer, so that you can have a congregation. Otherwise, we’re not looking for God anywhere.” Then there’s the lack of night and day in space. A lot of rituals depend on the time of day or year, timing that’s determined by the movement of the Earth, Sun, moon, or stars. For example, the Jewish Sabbath begins at sunset, many Buddhist holidays fall on the day of the full moon, and the dates of the spring and winter equinoxes are celebrated in many cultures. Going back to Islam for a moment, the timing of the five daily prayers follows the movement of the sun across the sky. But what if there is no sunrise or sunset, no afternoon or evening? Mehmet Ozalp: “Actually, Prophet Muhammad gave a solution to this, interestingly. In a saying attributed to him, he talks about the end of times, when there will be a day which will be like a year. Or he talks about a day which will be like a month, or like a week, like a month, like a year. So time, kind of, losing its normal sense. And his companions ask him, “How do we pray in that day?” And he says, you calculate. You work it out. So basically– This question came up for Muslims in Sweden or Norway, where there is, you know, six months there’s no sun. And the solution is that you either assume that you are in Mecca and you follow Meccan times, a 24-hour cycle, or you go with the nearest normal day, a latitude where it would give you a kind of a reasonable day where you can have proper, five daily prayers. So if you were to– If you were on a space station, that’s what you would do. You would have a certain set of times when you would pray your five daily prayers… In Mars, though, it’s a little bit easier, because Mars would have a day, as well. You know, the sun would rise. I guess depends where you land. If you land towards the poles, because there could be some frozen water or something, it’ll be difficult. Then you might do it like you were in Sweden or something. But if it’s– Assuming that it’s a normal latitude where you can have a proper day, sunrise, sunset, you can just work it out according to that. The only thing is the direction of prayer would be towards Earth.” Many religions will have to consider similar kinds of accommodations as their members move into space. You may be aware of another space-related religious ruling that made the news a few years ago. Here’s Michael Waltemathe again. Michael Waltemathe: “There’s one interesting example of the– what was it called?– the Mars One mission. Where a Dutch entrepreneur proposed sending humans on one-way trips to Mars. And the general Islamic authority of the United Arab Emirates actually issued a fatwā against that one. So, their argument was, if you go to Mars on a one-way mission, that could be compared to suicide. And suicide is forbidden in Islam. That was also their argument as the– The purpose of religion is basically saving lives. Going there deliberately to die would be forbidden within their religion.” I asked Mehmet Ozalp if he had heard about this ruling. Mehmet Ozalp: “Yes, I had heard about that. Well, I certainly heard about the planned trip to Mars. If they’re looking for an imam, I can go! [laughs] I’m happy to go.” Mehmet provided some more background on this issue, and gave me his own perspective on the ruling. Mehmet Ozalp: “The consideration about that fatwā of saying that it is not permissible to go to Mars, in a one-way ticket kind of way– It rests on the premise that in Islam, protection of life is extremely important. And one should not risk their lives if there is certain death. And I think in this case, the people who pronounced that particular fatwā thought that it would be certain death, going to Mars. I personally don’t think so… Yes, certainly, it will be quite difficult to survive on Mars. But it is possible, you know. And people are certainly going there to survive. So I think it is permissible in that respect. Certainly risky, but we can take risks in life. Nothing is certain. But the other aspect is, I guess, leaving the planet completely. Saying, “I’m going to live and die in Mars when my time comes.” I can’t see anything wrong with that, but it’s like, once again, going to another land and trying to settle in that land and take humanity’s frontier forward into– You know, certainly Mars is a creation of God from an Islamic perspective. It’s not an alien land where it will be a problem.” But death in space will become more common, and eventually inevitable, as people begin to settle there. And this brings us to another area in society where religion plays an important role: what do we do with our dead? Christianity and Islam will likely not have too much trouble adapting their burial practices to space: Christians have practiced burial at sea for centuries, and there has been a fatwā issued about how to handle Muslim bodies in space. But other religions place a greater emphasis on preserving or cremating the body, or returning it to its homeland for burial in the ground. What if observing these traditions is impossible in space? Michael Waltemathe: “I mean, the other thing is: What if the body is extremely important? How do you– For instance, if you’re in a self-sustainable space settlement and the person dies and you need the body as resources, what do you do with that? I mean, can you just– Now, or on Earth, you can just bury– you bury someone in the ground and we all know that it is repurposed by organisms back into the ecology. And you would probably need to do that in a self-sustaining habitat as well, but there is sort of a difference between putting somebody in a recycler and putting someone in the ground, right? So that is not so much, I think, an ethical as an aesthetical problem. But religions will have to address that.” Michael also talked another research topic of his: Why are some Christian groups against the exploration of space? And is there a theological argument for space settlement? Michael Waltemathe: “Joshua Ambrosius, he’s a political scientist. He’s at the University of Dayton in Ohio. He published a paper and he did research on Pew Research data, on sociological data. And his research showed that certain evangelical groups are more opposed to space exploration than other religious groups. And those are the same groups are also opposed to science. So my argument would be, if you want to talk to those groups and understand their problems with space exploration and sway them to support space exploration, if you approach them in scientific language and with scientific terms, they will probably not understand you, not listen to what you say. But if you approach them on religious terms, that is exactly where their problems come from. And then you can talk to them and understand, and maybe help solve some of their problems and get them on board in support of space exploration.” I mentioned to Michael that this sounds a lot like issues around climate change. Michael Waltemathe: “For instance, one of the arguments that you can find about not supporting space exploration is that end of the world is near. And if the end of the world is near, and we can expect it to happen in our lifetime, why have a space exploration mission that would take thirty years time? From thinking about it from getting the logistics done, getting the engineering done and launching the probe, waiting for it to arrive, and then for the data to come back– I mean, New Horizons probably took about thirty years to get to the point where it gave us this fabulous data that we now have. And if you fully expect the world to end in that period, why spend money on that, right? And…

    How can we prepare for medical emergencies in a space settlement? What equipment should we bring? What kinds of doctors? When resources are limited, who do we decide to treat first? Physician Ken Iserson talks about the lessons we can learn from remote and disaster medicine here on Earth. Philosopher Keith Abney highlights the ethical challenges of practicing medicine in a resource-limited environment like space. And physician Jim Duff discusses some things to keep in mind when selecting a medical team for a wilderness expedition. The transcript for this episode is below. Imagine this: Today started off like any other day in the space settlement where you live. You’re working in the community health clinic, sorting supplies. But around lunchtime, you hear a muffled explosion from the far end of the habitat. A call comes out over the radio: There’s been an accident at the power plant. The habitat isn’t damaged, but dozens of people are injured. As the patients come pouring into the clinic, you realize that you don’t have enough first aid supplies on hand to treat them all. And the last time anyone saw the community’s only doctor, she was heading for the power planet to check in with a former patient. No one’s heard from her since. What do you do? Welcome to Making New Worlds, a podcast about the ethical issues involved with settling space. I’m Erika Nesvold. Let’s talk about what happens when there’s a medical emergency in a space settlement. Specifically, what if there aren’t enough resources to treat everyone who’s sick or injured? Maybe there’s a disease outbreak, but not enough antibiotics to go around. Maybe it’s a flu epidemic, and you don’t have enough ventilators to keep the most severe cases alive. Maybe there’s been a large accident, with a lot of injured patients, but you don’t have enough medical providers to treat everyone quickly enough to save them all. How do we decide who gets treated immediately, and who has to wait? How do we choose who gets the life-saving treatment, and who doesn’t? This is a problem that medical providers often have to face on Earth, and the method they’ve developed to address it is called triage. Ken Iserson: “Triage is, essentially, sorting.” This is Dr. Ken Iserson, Professor Emeritus of Emergency Medicine at the University of Arizona in Tucson. He’s a physician and an expert in disaster international medicine who’s worked clinically or taught on every continent, including Antarctica. He gave me some background on triage. Ken Iserson: “And it comes from the French word trier, which means to sort agricultural products. But in reality, now, it’s strictly a medical term. And when we have limited resources, and that can be time– it’s always time– but then also personnel, equipment, we have to decide which patients get treated first and which will have to wait. That can be a really tough decision. It usually takes the most experienced health care providers, and sometimes a lot of fortitude, to do triage. Especially in really– in situations of big crunch. You know, there’s a lot of patients and very few resources, you have to decide who’s going to get treated and who’s not. And sometimes that means people are going to die.” These sorts of decisions about who lives and who dies can go beyond medical treatment. There’s a class of scenarios in ethics known as the lifeboat problem: Imagine you’re on a lifeboat that can only hold fifty people. But there are one hundred people in the water who will die if you don’t let them on board. What do you do? I talked with ethicist Keith Abney about how we might encounter the lifeboat problem in space. Keith is a philosopher at Cal Poly and also a senior fellow at the Ethics in Emerging Sciences Group. They study issues in the newest sciences and technologies that have ethical and policy components. Keith Abney: “Suppose we have a limited amount of oxygen and not enough to keep everyone alive until things get fixed. So, who are we gonna kill? And if we don’t kill anyone, then everyone dies. So how would we make that decision? This is something that would happen not only, potentially, in a spacecraft on the way to Mars, but let’s be clear, you’re going to be living under domes or in other kinds of limited facilities once you get there, or on the Moon, or, well, anywhere else in space. And it’s not only about oxygen. Suppose we have something that has to be immediately fixed, a solar panel, shielding for— against radiation, and there’s a solar storm. Who draws the short straw to go out and fix it and, quite possibly, die of radiation poisoning?” For now, let’s just focus on questions of medical treatment. How do you decide who gets treated first, or who gets to use the limited amount of medicine you have with you? It turns out there are a lot of different methods for making these decisions. Here’s Dr. Ken Iserson again. Ken Iserson: “Who do we decide on? There’s a number of ways you can do it, but one of the keys– and certainly in space that would be– one of the keys is they would have to decide how they were going to do this in advance. It’s not, “Let’s make a decision and set up a plan when something happens.” This has to be well planned out, certainly in a space mission. And usually in other long-term missions that have medical components, especially in resource-poor areas or after disasters.” Keith Abney gave me some examples of a few different approaches for triage. Keith Abney: “In medical ethics, there are considerable discussions about the best way to realize protocols for rationing. So one common approach is called, “QALY utilitarianism.” We’re going to do whatever— we’re going to give treatment out in such a way as to maximize the Quality-Adjusted Life Years of the patient. So if we only have enough resources for one cancer treatment, and there’s a twenty-year-old, and a eighty-year-old, then the twenty-year-old gets it. But by the same token, we might instead think about this in terms of traditional emergency triage, which is to divide patients into groups and using what’s called the “rule of rescue” as the primary principle, such that we prioritize treatment of those for whom treatment is a life-or-death issue. And only after we’ve treated all of those folks, do we treat people with non-terminal, non-lethal problems. Whether that’s a broken leg or a cold. And then last, and least, we treat those who we cannot save their lives, whose condition is terminal, and who really have only palliative care. If we decide to do things that way, that’s an entirely different approach, common in the military, but would cause very different decisions.” I have some experience with this last kind of triage, myself. I’ve been an EMT at a volunteer fire station for the last fifteen years, and I’ve been trained in emergency triage and used it in the field. This is the kind of triage most often used in emergency rooms, and might be the kind you’re most familiar with. It doesn’t matter who you’re treating, just what’s wrong with them, and how urgent their condition is. It can be tough to make those decisions, but in some ways it’s the easiest method of triage: you don’t have to try to think about the comparative value of the lives of the people you’re treating. But now imagine you’re in space, where the lives of certain people might matter more to the settlement than others. If those people die, then the whole settlement could die, because their expertise or training is lost. If you want to save the highest number of people in the long run, this could change the way you handle triage. Keith Abney: “Another way we could think about things is in terms of social value, or mission value. So, if we have to decide between the pilot of the craft versus a passenger, maybe we better save the pilot, right? If we have to decide between the person who’s responsible for keeping the atmosphere breathable versus a passenger, well, maybe we better make sure the atmospheric engineer lives. This is the kind of thing we might consider as well. All of these might well have different decisions when there’s a limited amount of medical care available.” Ken Iserson gave a similar example of this kind of triage, where it matters who the patient is, or more specifically, what their function is in the community. Ken Iserson: “Another is basically, treat and return to service those people who are most valuable to the team. In military, that seems to be pretty obvious. And the Germans did this in World War II, is they took their front-line soldiers and they tried to patch them up before anybody else. In civilian disasters, it might be the firemen, it might be the physician and nurse, it might be the rescue person, you know, who goes into buildings. If they get hurt, try to patch them up so they can maximize the good.” Triage isn’t just necessary in the fast-paced world of an emergency room or a battlefield. In places with more limited resources, like disaster zones or remote areas, triage can be a slower process, but these decisions still have to be made. Maybe you have a patient who is stable for now, but requires lifesaving care like surgery or chemotherapy in the next few months, or they’ll die. How much should the community contribute to helping this patient? Ken Iserson: “One thing that we didn’t talk about yet is the cost/benefit ratio. And sometimes, certainly in civilian settings, cost really means cost. How much might it cost to, for example, evacuate a patient from the South Pole in the winter? Certainly in terms of risk to the pilots, but also in terms of just the dollars and cents that it takes. That’s exactly the same scenario that would come to play in trying to evacuate a patient from a space station, let’s say.” Philosopher Keith Abney made a similar point about cost. Keith Abney: “In general, triage is going to be a huge issue because resources are limited. They’re limited here on Earth. Medical rationing is, in fact, a fact… Just, on Earth, it’s usually rationed by ability to pay. And so, poor people don’t get as much as rich people. In space, it’s gonna have to be more radically rationed, and we’re going to need to decide on the basis on which it’s rationed. Certainly, NASA doesn’t ration healthcare based on ability to pay. At least, not for the foreseeable future. But you could easily imagine, if you’re going up with Mars One or Elon Musk’s SpaceX, that you might be able to pay just a little, and be told, “You’re going have only minimal medical care on your voyage.” Or you could pay for the elaborate version, the platinum edition. And get much better guaranteed health care. There are all kinds of possible solutions to this, but we’re going to have to think through what we believe to be ethical and what we should allow.” No matter how you decide to fund your medical care, the amount of cargo you’ll be able to take on your initial founding of a space settlement will be limited. What do you bring with you to try to prepare for the largest range of possible emergencies? The question of what medical equipment and medication to bring is already being studied by groups like NASA, who have to think about this for the International Space Station. But what about the medical team? What kind of physician do you need to bring to space in the early days of your settlement? I put this question to Dr. Jim Duff, a retired GP and an expert in wilderness medicine who’s worked as the doctor on a number of expeditions in the Himalayas. Jim Duff: “First of all, I think the doctor has to be aware that he’s the Tail End Charlie in all this, because when he gets sick or ill, he– there’s no one, really, to back him up on the spot. I doubt there’ll be two doctors. There might be a paramedic or something like that. So I think the doctor has to be chosen very, very carefully. I think they’ve got to be psychologically fit, resilient and tough. And I think they’ve got to have, you know, it’s really– I see it as a– like, you’ve got to be a family physician with a very broad range of medical skills plus they have to have, you know, specialties like emergency medicine and a bit of surgery and so on. So they’ve got to have a really broad base of skills. And then, you know, a number of essential specialties.” As time goes on, more people will arrive in your space settlement, and you’ll be able to diversify your medical team. Here’s Ken Iserson again. Ken Iserson: “But after that, it will have to include the surgeon, and the obstetrician, and the anesthesiologist, as well as other people who can treat what will inevitably occur medically in those situations. You can’t send them back immediately, you’re going to have to have a robust enough team– medical team to treat what you know is going to happen.” But initially, there’ll be a lot of pressure placed on the few doctors in the settlement. This can potentially be really dangerous if the person with the highest level of training is the one who needs medical care. There are a few examples of this happening in Antarctica when there was only one physician present at a base. One of the most well-known examples is about a doctor in Antarctica who removed his own appendix. Ken Iserson: “It was actually a surgeon. It was decades ago. There’s a photo of him doing it. Or more than one photo of him doing it. It was a Russian. I’m sure he was paranoid. He didn’t want anybody else touching him, so he used a set of mirrors and he did an appendectomy on himself. I can’t think of anything worse [laughs] to do. Although, at one of our stations, a number of years ago, the physician actually came down with a large abscess in her mouth. She couldn’t drain it herself. So, using mirrors and instructions, she had the other, non-physician clinician drain it.” One key component of space missions, and a very important part of future space settlements, is cross-training. If only one person knows how to work the life support system, and that person is killed, then everyone dies. So you want to cross-train your crew to make sure that you have redundancies built in. Ken Iserson: “Well, we do cross-training. But you can’t cross-train someone to be a surgeon. You know, a general surgeon. We do dental work, including extractions and fillings and other things. And that’s cross-training, the physician generally does that. But you can’t– you just can’t train someone adequately to do general surgery. You know, in a week or whatever.” Fortunately, on Earth, technology allows us to take advantage of experts on the other side of the planet, even if you’re stuck in a remote location with a patient in need of more care than you can give them. Jim Duff: “Traditionally, you would go off into the Himalayas and you’d be away for, you know, a month, two months, three months. And you’d come out again. And if someone got sick, it was pretty much, you had to carry them out. Then helicopters came in. And then sat phones. So you could actually, you know, someone gets frostbitten on a Himalayan expedition these days, I mean, you just take some pictures and email them to the experts in the various countries you come from, and you get direct advice. And I can imagine that could be a quite– you know, with the– Once we get to the technological level where we have bases on Mars, that we’d probably put in a kind of surgical robot, and you could have telemedicine. Might be a bit of a delay, might be a slow process, but, you know, maybe you’re remote in terms of experts getting their hands on the– physically, on the patient, but there should be, one would assume, you know, a vast array of expertise available through telemedicine.” That “bit of a delay” in communications could be significant, the farther we travel from Earth, but initially, we will at least be able to do some slow research for non-emergency situations. Ken Iserson stressed the importance of having remote consultants who understand your situation and limitations in space. Ken Iserson: “You want to have the best possible consul…

    Ep 09: What If There’s Already Life on Mars? Jan 24, 2018
    Show notes

    How do we make sure we don’t bring harmful extraterrestrial microorganisms back to Earth from space? How do we keep our Earth microbes from contaminating potentially habitable worlds like Mars or Europa? How much effort do we really need to put into protecting these hypothetical lifeforms? SETI marine biologist Margaret Race joins us to explain how NASA approaches these planetary protection problems. Philosopher Kelly Smith explores the ethical questions about the moral value of extraterrestrial life. And theologian Michael Waltemathe presents a religious perspective on planetary protection. The transcript for this episode is below. Imagine this: Your space settlement wants to expand into a new region of the surface. But the surveyors have just reported back, and there’s a problem. They’ve discovered evidence of microbial life in an underground pool near where you want to build. The biologists are already arguing with each other about whether this is truly extraterrestrial life, or just some invasive Earth bacteria brought here by the settlers. But the engineers are pointing out that the power plant you were planning to build in the new area will almost certainly be harmful to this tiny ecosystem. What do you do? Welcome to Making New Worlds, a podcast about the ethical issues involved with settling space. I’m Erika Nesvold. Today’s episode is about the possibility of extraterrestrial life. Specifically, the kind of non-intelligent, microbial life that scientists speculate might exist in certain places in the Solar System, including Mars. We don’t know whether this life exists, or even what it would look like, but we have to consider the possibility that this hypothetical life might pose a threat to life on Earth, or vice versa. This issue is called planetary protection, which refers to both protecting the planet Earth from contamination by extraterrestrial life, and protecting other planets from contamination by Earth life. Planetary protection is not a new idea. In fact, it’s covered in Article IX of the Outer Space Treaty of 1967, which requires that the exploration of space avoids both the “harmful contamination” of the Moon and other celestial bodies, and any “adverse changes in the environment of the Earth” due extraterrestrial material. NASA has an Office of Planetary Protection that maintains policies to ensure that missions don’t violate this part of the treaty and other planetary protection regulations. This is one of our more science-y topics, so I called up a scientist friend of mine and an expert in planetary protection to walk us through some of the challenges. Margaret Race: “My name is Margaret Race, and I’m a marine biologist and ecologist who works with SETI Institute. And I am a contractor with NASA who asks questions about planetary protection.” Margaret got into the planetary protection business on the back contamination side of the problem — the question of how to prevent extraterrestrial microbes from getting loose on Earth. She was studying invasive species on Earth at a time when NASA was really starting to think about how to prevent bringing back invasive species from space. Margaret Race: “So I got a call from someone at NASA who said, would I come to a workshop? They were beginning to talk about sample return– now this is, mind you, in the early 1990s– and said we want to think about how we would include questions of risk with sample return and environmental impact statements. How would you build the lab to take samples from Mars back to Earth? And how do you tell people in an environmental impact statement that, “Don’t worry, we can handle it”? So these are questions that any federal government agency has to think about when you’re proposing to spend money on a new technology, new siting of something.” Even though they were planning for it back in the 90s, we still haven’t done a sample return from Mars yet. But we have brought back samples from another celestial body: the Moon. In fact, we even sent and brought back people. The Apollo program put a lot of effort into preventing back contamination. Margaret Race: “We know that when the astronauts went on the Apollo missions, there was quarantine. We did contain things. Materials were handled in glove boxes in order to make sure that we didn’t inadvertently introduce something to Earth. However, that was back in the late 60s, early 70s when we were designing this. And I tell students, if we– If there were life on the Moon, we would have it here. We didn’t know about the microbiome and how many microbes are associated with humans. Our view at the time was really that, you know, germs cause disease. And we didn’t have this same, larger view of, you know, biogeochemical cycles and things like that. So when NASA and the international community began talking about bringing back samples from Mars in robotic spacecraft and/or bringing back humans from Mars, they took that protocol and quarantine specifications that were done in Apollo and really looked at them carefully and said, “How would we go forward from here?”” So now that NASA is starting to talk about sample return from Mars again, and now that lots of different groups are talking about sending humans to Mars, people are taking a fresh look at our backwards contamination protocols and technologies. And not just for NASA — for everyone who wants to bring material or people back to the Earth from space. Margaret Race: “And so right now, the international community is saying, “Let’s take a look at sample return again. And so they– This spring, there’s a meeting in Germany, looking at European sample returns. And also, the U.S. is looking at it as well. And each one of them has to be done to protect the science and the astrobiology questions. But also it has to be done in accordance with the science requirements and legal policies and laws of the country where it’s placed. So if we have a sample return facility in the U.S., it would have to follow U.S. law. And likewise, if a commercial group was coming back and we hadn’t found out about Mars yet, the commercial group would also be subject to the same kind of restrictions. Doesn’t matter that you’re bringing something back– If you’re coming in from a vacation in South America and they stop you and ask, “Have you been on a farm? Do you have any fruits or vegetables?” They also stop container loads of things coming in, as well. So it doesn’t matter whether you’re commercial or not. The law still holds. So for thinking about humans to Mars, we’re now looking at, okay, how would you do that? And what are the big research questions we still have to address? So this is happening very much, now.”” You don’t even have to read or watch science fiction to understand the risks of backwards contamination. Just look at the problems we have on Earth with communicable diseases or even just invasive species. Quarantines and customs checks for people visiting the Earth from a space settlement might just become a part of the routine, just like it is for international travelers on Earth today. But then there’s the other half of planetary protection: forward contamination, what the Outer Space Treaty calls “harmful contamination” of the Moon or other bodies. Again, this idea is decades old, and some of the earliest concerns were about scientific integrity. Margaret Race: “Surprisingly, in the– at the time of Sputnik, so this is back in the 19– late 1950s, a group of biologists were already saying, if we can send spacecraft out there to the Moon and beyond to look for life, we don’t want to spend all this– these millions and millions of dollars, now billions, and get up there and discover life but find that it was launched with our spacecraft from Earth.” Let’s say we send a few missions to Mars. Suddenly one of the missions comes back with exciting news: they’ve discovered extraterrestrial life in the form of tiny microbes living on the polar ice caps on Mars. But if humans have been bouncing around the surface of Mars for a few years, how can we be sure that we didn’t bring that life with us? Sure, maybe these new microbes will look significantly different than Earth life, but what if it’s been decades since humans first set foot on Mars? What if those first Earth microbes have just evolved to thrive in their new environment? Or maybe it’ll be really obvious that this Martian life couldn’t have evolved from Earth life. Maybe it will have a completely different DNA structure, or won’t have DNA at all. There’s still the possibility that our presence on Mars could harm these microbes, even wipe them out. After all, we’re pretty good at causing species to die out on Earth without even trying. And Mars is already a harsh environment. If we show up on Mars with our industrial-strength cleaners and nuclear power plants and Earth viruses, we might kill off the local life before we even get the chance to study it. Kelly Smith: “If you’re saying, well, the goal is to preserve, say, microorganisms, so that we can study those microorganisms, then to some extent, there’s a scientific fix for this problem.” That’s Kelly Smith, a philosopher at Clemson University. He studies social and conceptual issues surrounding astrobiology. Kelly Smith: “The question would be something like, how diverse are the microbes that are going to be endangered, you know? Maybe you shouldn’t locate your human settlement in a particularly delicate, rich ecosystem because you’re going to be destroying microbes that will never be seen again. If there’s a particular species of microbe which is ubiquitous on Mars, it’s everywhere, then there’s less of a concern in the same way that there’s less of a concern on Earth if building a settlement chases off several field mice. We don’t really spend a whole lot of time worried about that, whereas snail darters or some exotic species of zebra or something like that, that’s much more concerning.” Kelly pointed out that some of the most interesting areas of the forward contamination issue involve conflicts between scientific interests. Kelly Smith: “Let’s suppose that there’s a warm, salty ocean underneath the ice cap on Europa. And we have reason to suspect that there’s life down there, like we’ve sampled some of the steam coming off the vents, and there are cells! And so we think, “Oh my gosh! There could be a really complicated ecosystem with fish and maybe even mammals and stuff down there.” But there’s absolutely no way you can put a probe down into the Europan ocean without contaminating it. It’s just not possible. So if the point of preserving life is to preserve the science, but you can’t do the science at all without taking some risk, now you’ve got a real quandary, even if everybody agrees it’s all about the science, you’re gonna have scientists arguing with each other. And that, I think is where things get more interesting.” But let’s set the question of science aside for a moment. Is it really okay for us to invade another planet and start remodeling the place if it means potentially killing the local lifeforms? Kelly Smith: “So you might be concerned with life on Mars for its own sake, irrespective of what science you might do on it. If you’re concerned about life on Mars irrespective of the science, then in some sense it doesn’t matter how diverse the microbes are that you’re destroying or not inconveniencing by your settlement. It might be unethical have a settlement on Mars at all.” So if we take this argument to its extreme, it means we should never go anywhere that might potentially harbor life, for fear of harming that life. On the other hand, remember that we’re talking about microorganisms here, at least for Mars. Kelly Smith: “Although in principle, that argument makes a lot of sense, I think I and a lot of other ethicists would say, “Uh, you’re talking about microbes, that’s a difficult argument to make.” Because you have to first grant that microbes, as a class of organisms, are somehow on the same level with human beings and that’s– I’m not saying you can’t make an argument to that effect, but it really stretches credulity. So it’s an uphill battle.” I asked Kelly if this means that the argument might be a little different if we discovered more complex life in space, not necessarily intelligent life, but maybe something a little bigger than a microbe. Kelly Smith: “I think almost everybody, including professional ethicists, but also just your average guy on the street, if you say, “Gosh, doing this mission is going to kill five billion really common Martian microbes,” people will yawn. But if you said, “Well there’s Martian bunnies, and we’re gonna kill a whole bunch of them,” then people are gonna get very upset. You know, when I was in graduate school, one of the most important things I learned is the fundamental distinction in biology between warm fuzzies and cold pricklies. You can do whatever you want to to a cold prickly and people just don’t care. You can take a sea urchin and inject it with potassium chloride and watch it go into spasms and everyone thinks it’s just interesting. But if you did that to a bunny rabbit, people would freak out. And so that’s just an intuitive reaction, but I think that even most professional ethicists would say you can give a legitimate justification for that. Maybe not quite the way people cash it out intuitively, but it’s not silly to think that, for example, more complex, social organisms have a higher moral value that a microbe… People, for example, have probably way too much emphasis on human value and on mammalian values, because those are like us. But nevertheless, multicellular versus single cellular, that’s not too hard to defend.” The story is also different if you’re talking about the extinction of an entire species, instead of just a small portion of the population of microbes on the planet. Kelly Smith: “All the Martian microbes are all representatives of particular species of microbe? Then what you’re really talking about is not microbes, but a species or a microbial ecosystem. And that clearly ups the ante. Though again, how much is a bit unclear.” When I asked marine biologist Margaret Race about whether we had the right to harm extraterrestrial life in the pursuit of space exploration and settlement, she said this question goes way beyond the legal and scientific questions that she works on. Margaret Race: “So the Outer Space Treaty, the way it was written, and the Section IX– Article IX, which talks about avoiding harmful contamination– When you really look at it, the lawyers look at it in recent years and said actually, what it focuses on is avoiding harmful contamination that would affect your science. And then they said, “Hm, that doesn’t have anything to do with protecting Mars, for instance, or protecting other bodies that you’ve gone to. What are our obligations there? And what if we find life out there?” So you have touched on things that go even beyond the science, beyond the law and the policy and touch on legal and– I mean, ethical and philosophical, and I would even say theological, questions. If you find microbes on Mars, and they are different and we can just show that scientifically, they’re different than anything we know of on Earth, and they don’t maybe have DNA or they don’t map on our tree of life that taxonomists and biologists have worked out, does that make them a second Genesis? That’s not a science question. Scientifically and otherwise, a discovery of life someplace else would be amazing. Highly significant. But, if that– you want to talk about meaning, I can give you the astrobiological and science meaning and I also am interested in how that plays over the policy. But you would need an ethicist or a theologian to talk about what it means to a Buddhist, or what it means to a Muslim, or a Christian of some sort. Or to an atheist.” So let’s get a theologian’s perspective on planetary protection! Michael Waltemathe: “[laughs] That’s a…

    Ep 08: Should We Make Mars More Like Earth? Jan 17, 2018
    Show notes

    How do we balance out our hunger for resources in space with the desire to preserve the space environment for future generations? Will something inherently valuable and important be lost when we start transforming the Moon or Mars to extract resources and make habitats where we can live? How should we preserve our history on the surfaces of other worlds? Space lawyer Christopher Newman rejoins us to talk about how environmental conservation might be regulated in space. Philosopher James Schwartz discusses the ethics of mining and terraforming other worlds. And space lawyer Michelle Hanlon tells us about For All Moonkind, an organization dedicated to preserving our historical space heritage. The transcript for this episode is below. Hello! This is Erika Nesvold from Making New Worlds. In case you’ve been following our schedule on the website, I wanted to point out that we’ve rearranged the order of the next few episodes. I also want to point out that Episode 12 will be an audience feedback episode. We want to hear from you! You know all those questions I ask at the end of each episode? If you’ve got answers, send them our way. Maybe you disagree with something we’ve said, or you have a question about something we haven’t covered. Send a written comment or audio file to makingnewworldspodcast@gmail.com by February 7th, and we might include it in our episode. Now onto today’s episode. This is Making New Worlds. Imagine this: You’ve got the day off from your job working on the space settlement’s life support systems, so you decide to put on your pressure suit and go for a hike. You head for your favorite spot: the top of a crater ridge to the north, overlooking a fantastic view. But when you get up there, you see a sign posted: Development Coming Soon. Some waste disposal company has gotten the rights to dump toxic waste here. Soon they’ll be tearing up your beautiful view, and you won’t be able to come anywhere near it without risking radiation exposure. Is there anything you can do about it? Or will you just have to find another favorite hiking spot? What happens when more and more of the nearby surface gets taken over by waste disposal, mining, and new habitats? Welcome to Making New Worlds, a podcast about the ethical issues involved with settling space. I’m Erika Nesvold. Today’s episode is about environmental conservation in space. Space may be infinite, but the amount of valuable land and resources that are within our reach is limited, and will be in high demand. How do we balance out our hunger for resources with the desire to preserve something for future generations? Is there something inherently beautiful and valuable in the untouched landscapes on the Moon or Mars? Will something important be lost when we start transforming that land to extract resources and make habitats where we can live? The topic of environmentalism is always at the edges of conversations about settling space, because the deteriorating environment on Earth is one of the big reasons that space enthusiasts point to for spreading our species off-world. But the early space pioneers weren’t particularly concerned with environmental conservation, either here or in space. Here’s space lawyer Christopher Newman again, talking about our old friend, the Outer Space Treaty. Christopher Newman: “One of the things that we find is that space activity and space regulation is shaped by one instrument, and that’s the Outer Space Treaty of 1967. Now, again, as I kind of say to all of my law students, if ever you want to understand a piece of law, then look at the law it was passed. 1967: environmentalism wasn’t in the mainstream, it wasn’t a consideration. Getting to space was difficult enough. It was an achievement just getting up there. We didn’t worry quite how we got up there. We certainly didn’t worry about leaving things there. So you look at the Apollo mission, for example, tremendously wasteful, tremendously environmentally unfriendly, you know? There was a lot of stuff left on the Moon, because it was– it would save weight, you know, not bringing it back. And there wasn’t really a discussion, as well, what type of damage are we doing to the lunar environment, what type of damage are we doing to the Earth’s environment? Just getting up there was an achievement.” A lot’s changed since 1967. The environmentalism movement has grown, and people are more aware of the damage we are doing to the planet Earth. Meanwhile, that damage is increasing, as our population and energy requirements grow. And our increasing dependence on technology is affecting the space environment, too. Specifically, low-Earth orbit. Here’s the problem: for decades, countries on Earth have been launching spacecraft into low-Earth orbit: telecommunications satellites, military spy satellites, GPS navigation satellites, astronomical telescopes. Sometimes, when a satellite gets too old, its controllers on Earth fire its thrusters one last time to either deorbit it back down to Earth, or send it out into space. But a lot of the time, it’s just deactivated and left in place. So this space junk just stays there, hanging around in orbit. As time passes, the problem gets worse. Sometimes satellites collide, breaking into smaller pieces that spread out along the orbit. All of these pieces of debris are moving incredibly fast, and are hard to track, so they pose a danger to other satellites and spacecraft. NASA says there are over half a million pieces of orbital debris larger than a marble, and millions of untrackable smaller pieces, and those numbers are only growing. Christopher Newman: “The mess that we’re making in low-Earth orbit, the mess that we’re making due to space debris. What we’ve– You know, if we go to the planets, if we go to the Moon, if we go to Mars, we’re gonna need infrastructure. We’re going to need that satellite network for communications, for navigations. We’re gonna have similar problems if we’re not careful, that we’re exporting. And that’s just before we even land on the planet. That’s just putting the infrastructure in place to have a useful human habitat.” This problem is a big deal in the space community, and a lot of people are discussing what can be done to clean up this debris before the problem gets worse, but it doesn’t seem to be talked about much by the general public, with the exception of the movie Gravity from a few years ago. Christopher Newman: “And I mean, I think the problem is, there’s a lot to be said for when you can’t see the manifestation of the problem, it doesn’t become that much of a problem, you know? In Western society and across the world, actually, we’re beginning to see quite severe, profound climate change. And that climate change is, you know, accountable to human activity. And we’re seeing that, but we’re not seeing orbital debris. People can’t look up and see the skies are clouded. People can’t look up and see the dangers from hundreds of thousands of small fragments. So it doesn’t exist, so there’s an advocacy job to be done, as well. You know, as well as a regulatory job.” So let’s say we’ve dodged all the debris and made it out of low-Earth orbit. We’re out in the untouched wilderness of space. What’s the first thing we’re going to do? Well, according to a lot of the space companies today, we’re going to grab a space rock and start drilling. Christopher Newman: “A lot of the discussion around contemporary space activity on other planets tends to revolve around mining activities, and humans as workers. I think, you know, from my knowledge of the mining industry, it’s very difficult, there’s no really such thing as an environmentally friendly mining activity. So we’re inherently affecting the environment of the planet, of the celestial body that we’re going onto, if we’re looking to use it purely as resource utilization.” There’s a lot of discussion about the feasibility of asteroid and lunar mining in the space industry now. In particular, space mining companies are trying to convince investors that it’s a profitable enterprise, that you can get enough water and precious minerals out of space to make it worth the cost of going up there. We talked about some of this in our economics episode. But today I want to talk about the resources themselves, not the economics of asteroid mining. Sounds like a job for an ethicist. James Schwartz: “I’m James Schwartz, I teach philosophy at Wichita State University. And what I mostly research is philosophy and ethics of space exploration and space policy.” James has been doing some recent work on the ethics of resource extraction in space. He argues that these mining resources are more limited than a lot of people imagine, especially when you take into consideration how difficult it is to reach the asteroids you want to mine. James Schwartz: “Because, you know, we’re talking about exhaustible resources, as well. Not just limited resources, but exhaustible ones… These are the kind of things that are gonna get used up pretty quickly. And once they’re gone, you know, it’s not as though somebody can just hop in at the next slot and do everything they wanna do. So I tend to think that from a sort of philosophical or ethical point of view, it matters what you’re gonna do with the stuff. So I’m not as concerned about issues with fair access as I am concerned with issues of fair use, here. Because when you have extremely limited resources, now it becomes even more of an ethical decision about, you know, what are these resources gonna be used for? Are they just gonna, you know, satisfy some really rich person’s desire to have a hotel on the surface of the Moon? Or is it going to do something like contribute to valuable human scientific research?” But let’s set aside the problems with mining and resource extraction for a minute. Humans are perfectly capable of damaging an environment just by living in it. Do we need to worry about environmental conservation when we’re building our space settlements? What if someday we go beyond building domes or underground habitats, and start trying to terraform another planet? Scientists and engineers have proposed different ways for creating and maintaining an Earth-like atmosphere on Mars, bringing back the Martian oceans, and protecting the surface from radiation. If humankind can someday pull this off, we could live on the surface of Mars without needing spacesuits. But we will have fundamentally changed the face of the planet. Is this morally okay? The answer to that question sort of depends on whether we end up finding life on Mars, which is still a bit of an open question. Let’s assume for the moment that there’s no life there. James points out that this removes a lot of the arguments for environmental conservation. James Schwartz: “So, the challenging question about terraforming, especially if we think that Mars ends up being lifeless, is, how do you have a reason to preserve or protect a lifeless environment? Because if you look at most views of environmental ethics, the thought that there’s some ecosystem there that ought to be preserved is a real guiding thought. Maybe it’s not an ecosystem, maybe the focus is on the species level, or the individual organism level, but the presence of life has been very important in most views. So it becomes challenging, then, when you’ve got an environment that you take to be completely lifeless. And so you have to sort of get a little creative in terms of the ethical argumentation that you provide. Maybe the claim is that something of great beauty is there and would be lost. Maybe the claim is something about how, you know, even if there’s no life there, it would still demonstrate this great hubris on our part to completely remake a world. Maybe we can describe planetary surfaces as just valuable in themselves. And I don’t think any of these are incoherent claims, but I think they end up being fairly difficult claims to provide good justifications for.” But what if there is life on Mars, even just microbes? If they’re thriving in the Martian environment, they likely wouldn’t do so well if we terraformed Mars to be more like Earth. Here’s space lawyer Chris Newman again. Christopher Newman: “What do we do, for example, if we discover microbial life on Mars? Are we in a situation of contaminating that environment? Yes, we’re obviously going to contaminate it to an extent. But if we then inhabit the planet, you know, are we an infestation? I mean, I’m using quite crude terms there, but it’s something that I think we need to start having the conversation about.” This gets into a topic called planetary protection, which we’ll spend a whole episode talking about next week. For now, I want to point out one more thing we need to consider when we think about the changes we’ll make to the surface of places like the Moon or Mars, and that’s historical conservation. Neil Armstrong: “That’s one small step for [a] man, one giant leap for mankind.” Thanks to the lack of weather on the Moon, the Apollo landing sites, including the first footprints made by a human on another world, haven’t been washed away by wind or rain. They’re perfectly preserved– If you had a spaceship, you could go look at them right now. But if everyone had a spaceship, they probably wouldn’t last too long, thanks to all the tourists that would be bouncing around on the Moon’s surface. Is there something we can do to protect these historical sites from future space tourists? I’m glad you asked. Michelle Hanlon: “Hi, my name is Michelle Hanlon. I’m the co-founder of For All Moonkind, which is an organization which is dedicated and committed to preserving our human heritage in outer space. That means that we want to create international guidelines that will protect all of our first footsteps in outer space, starting with the Apollo lunar landing sites.” Michelle is a space lawyer, and her organization is staffed by lawyers from around the world who volunteer their time to try to figure out how to put protections in place now to prevent damage to historical sites on the Moon in the future. Michelle Hanlon: “In thinking about how we go to space and how we explore space, we really need to focus on what we’re gonna take of our own civilization into space. And we need to make sure that we take some of our civilization into space, because it will be very easy to end up with tyrannies. So, the first step in a world where our superpowers and up-and-coming powers can’t agree on much with respect to outer space, I think we can start with agreeing that those first footsteps, these were technological achievements that can be shared by humanity. And so if we can recognize those footsteps– both Apollo and Luna and, you know, the Jade Rabbit from China– recognize those as universal achievements of humanity, maybe we can start our exploration of space on the right foot as a human species and not as a particular nation or commercial entity.” I asked Michelle to talk about why she thought that these historical sites, in particular, were so important and worth preserving. Michelle Hanlon: “We mark achievements that we make as a human species, as a culture. The first footsteps in space, whether by man– human, or by rover are an incredible technological achievement, one that is unparalleled. And it is that– It is, like I said, the threshold of our exploration of space. It marks a change from being an Earth-bound species to a space-faring species. It’s really important to protect and preserve those first footsteps, because they say a lot about us as a species. The fact that there’s three different nations, you know, different flags, that’s a history that we have to protect and preserve and remembers as we go forth to colonize the Moon and elsewhere. We want to be able to look back and remember, “Okay, we came to the Moon in the midst of a Cold War, but look how far we’ve advanced since then.” Or, “Let’s remember that Cold War and make sure we don’t slip back into…

    Ep 07: What If I Want to Have Kids? Jan 03, 2018
    Show notes

    How do we sustain a stable population in our future space settlements? Do we require settlers to reproduce? How do we limit population growth when resources are scarce? What rights do children born in space have? Is it even possible to safely raise children in space? Physician Shawna Pandya joins us for a discussion of the challenges of biological reproduction in space. Bioethicist Rebecca Kukla explores some of the potential problems and pitfalls around reproductive rights in a resource-limited environment like a space settlement. The transcript for this episode is below. Imagine this: You’ve been living and working in humanity’s newest space settlement for a few years, now. Your little community has hit a few bumps along the way, but you’ve pulled together and dealt with every obstacle you’ve faced. The settlement is becoming self-sustainable: you grow your own food, make your own power, and have even started to turn a profit on the interplanetary mineral market. People are beginning to make long-term plans, plans that include the next generation of citizens in your community. But do you have enough spare resources to spend on raising children? What if people don’t have babies fast enough to replace the aging population? Is it even possible to safely conceive and raise kids in space? Welcome to Making New Worlds, a podcast about the ethical issues involved with settling space. I’m Erika Nesvold. Today’s episode is about reproduction in space. How do we maintain a sustainable population in a space settlement, without harming prospective parents or their children? If you decide you do or don’t want to have children in space, how much of that decision is yours and how much will be influenced by the community’s needs? Human reproduction in space has never been tested, and we know so little about what the biological challenges might be, so this episode will include even more speculation than usual. For a quick background on the potential medical hazards, I talked with a physician who does research on this topic. Shawna Pandya: “My name is Dr. Shawna Pandya. I am a licensed physician in general practice, and doing some extra training in surgery. I am also a citizen-scientist astronaut with Projects PoSSUM and PHEnOM. And I also do space-related research in psychological resilience as well as reproduction and sexuality in space.” I asked Shawna what some of the challenges would be for someone who wanted to conceive and raise a baby in space. Shawna Pandya: “The short answer is that space is trying to kill you… Every life form of all the species we have, whether, you know, primate or not, mammalian or not, despite having such a wide array of species and life here on Earth, every single one of them has had the luxury of developing in 1 g. The radiation has been constant, and– has been near constant, and the gravity, the 1-g gravity environment has absolutely been constant… There’s a huge breadth of literature on astronauts who are fully developed adults and how they fare in the zero-gravity environment, and every bodily system, whether you’re talking about their vision, or their nervous systems, or their immune systems, they’re affected. And often adversely so. And so, when you bring the question of, can we safely reproduce in space? There’s so many unknowns. And you can’t help but suspect that those effects that we see in developed, fully developed adults would be amplified in developing bodies.” It might not even be possible to conceive viable fetuses in space, in which case the people in future space settlements will have a huge hurdle to overcome in terms of becoming independent from Earth. But there’s no way to know without trying it. Even if we do a lot of research with animal reproduction in space, we’ll still eventually have to experiment with actual mothers and babies. Now we’re getting into medical ethics, so I called in an expert. Rebecca Kukla: “My name is Rebecca Kukla. I’m a professor of philosophy at Georgetown University, where I’m also a senior research scholar in the Kennedy Institute of Ethics… So I’ve worked on topics from health communication and analyzing things like public service announcements around early motherhood and pregnancy, to how we do science and communicate about science around risks during pregnancy, to topics like what kind of obligations, if any, do mothers have to try to produce certain kinds of babies or avoid producing kinds of babies and that sort of thing.” Rebecca pointed out that trying to experiment with safe methods of reproduction in space could violate a lot of the research ethics protocols we have here on Earth. Rebecca Kukla: “I mean, the thing is, actually, if you look at our research ethics principles and protocols on Earth, if anything, we’re overly stringent when it comes to experimenting on fetuses and embryos and pregnant women. We let pregnant women engage in almost no research protocols. Even just completely theoretical, tiny risks rule women out from participating in research right now. And I think that’s actually a problem in the other direction. But what we would, in effect, be doing is swinging all the way to the other side. And it wouldn’t be part of an official research protocol, but we would, in effect, be doing incredibly risky research in this kind of uncontrolled condition. And that does go against what we think of as standard principles of research ethics.” But let’s suppose we’ve crossed that bridge and we’ve figured out that it’s possible to bear healthy children in space, or on other planets. Maybe it takes some extra effort or technology, like medicine or specialized life support for the newborn. Or maybe fetus development isn’t a problem, but the baby can only be delivered surgically. What does this mean for our bare-bones, brand-new space settlers, who are surviving on whatever supplies they brought with them from Earth? Shawna Pandya discussed some of the potential problems. Shawna Pandya: “The other challenge is– comes with the trade-offs that come with being able to support gestation and birth off-world. So, even now, on current space missions, there’s always trade-offs when it comes to medical supply kits. You’re limited by mass and volume. And the way you determine what you bring with you on your… space mission is what scenarios are most likely to come up, what is lightweight, has a long shelf life, and can be used for more than one medical condition. Now, you throw in something like a pregnancy in there, and suddenly you have a very wide need of medications and specific medical tools that may not be able to be used for other areas of medicine. And that may take up their own sig– not insignificant mass and volume on a space mission. So for example, consider that here on Earth, you know, a basic hospital, so even the furthest hospitals, they might not have C-section coverage, and they have to accept that. But then they have to send their higher-risk pregnancies to a facility that has an OR and could theoretically perform a C-section in an emergency situation. But at least they would have forceps, and vacuums for– and they have monitoring equipment specific to the fetus during delivery. You always have to be prepared for, you know, what’s the worst that could happen? And so that’s, you know, that becomes an ethical quandary. You know, if you have limited mass and volume, where’s the trade-off?” Even later down the line, once a settlement has been established, it’s possible that conception and childbirth will remain something that’s very costly and difficult, either because you need extra support biologically, or because the expense of raising a child is so high. Does that mean that only people who can afford it will be able to have children? In fact, the extreme limitations of a space settlement could make child-rearing costly for the whole community, not just the parents. Shawna Pandya: “Because now not only do you have a crew member who’s likely going to have to go on some sort of maternity leave, the rest of the crew is picking up the slack now and filling in for the duties of the crew member who’s on medical leave. And then once the baby’s born, there’s now an extra mouth to feed.” If your settlement is only producing enough food to barely feed all its inhabitants, what do you do with a baby who not only can’t contribute any labor to the community yet, but requires other people to divert their labor to taking care of them? What do you do when a baby is born with extra needs in terms of care or resources? Here’s Rebecca Kukla again. Rebecca Kukla: “Presumably, at least at the beginning, there would be enormous and understandable pressures to, to whatever extent possible, produce healthy children who would be able to fully participate in continuing to found that colony. We would have way less infrastructure in place, both in terms of medical care, and in terms of social services– and even, I guess, in terms of educational services– we’d have way less infrastructure in place, for instance, for dealing with disabled or special needs children. And so aside from the risk issue, one of the concerns I have is, there’s already, here on Earth, increasing pressure on prospective parents to abort fetuses who prenatal tests show are going to be disabled or have special needs. And I worry that there would be heightened pressure to abort disabled fetuses in space colonies, especially at the beginning, for resource issues, if nothing else.” This might remind you of something we discussed in the second episode of the podcast with astrophysicist Jesse Shanahan. Jesse argued that it’s better to make our space settlements more accessible instead of just requiring every space traveler to be healthy and able-bodied, because disability can happen to anyone. If we’re not prepared to welcome disabled space settlers and make it possible for them to live in and contribute to these new societies, what’s going to happen to the settlement’s children who are born disabled? Rebecca Kukla: “…This would enforce a horrific kind of ableism where we dramatically disvalue children who have special needs or who can’t contribute in the same way to the propagation or founding of this colony… It would be a breeding ground, so to speak, for the worst kind of eugenic impulses, where people would start being under enormous imperatives to design specific sorts of babies that are gonna have the right qualities to propagate in the way that’s seen as valuable in that community. We have a long history of ethical concerns about that kind of eugenic program.” Even before the baby is born, there will be a huge amount of pressure on its pregnant mother to ensure that her child is developing in a safe and healthy way in the extremely unsafe and unhealthy environment of space. Rebecca Kukla: “I think that women already face enormous, disproportionate burdens to manage risk during pregnancy and to discipline their bodies during pregnancy in ways that are often contradictory and impossible. So you’re supposed to not exercise because it might be dangerous, but you’re also supposed to not get out of shape because that might be dangerous. You’re supposed to, you know, manage your emotions, because being overly emotional could be dangerous, but you’re not supposed to take any drugs to manage your emotions. So, women are already asked to police their bodies during pregnancy… towards the goal of producing a healthy baby in ways that are nearly impossible if not impossible to carry out. And I feel like if we add on a whole set of unknown risks, and say, “Well, for all we know this might be dangerous, we really just don’t have any idea,” women are gonna be caught in a position of trying to manage so many risks, both theoretical and actual, that they won’t have control over their bodies at all, or be able to act in any way at all that’s considered acceptable. So that strikes me as a serious concern.” Even on Earth, babies are a massive drain on resources for the first few years of their lives, and in a world where even the air has to be imported or produced, overpopulation could be a big threat to the existence of a space settlement. So how do you keep your population under control? Mandatory birth control? Requiring permits to have children? A legal limit on the number of kids that each settler can have? All of these ideas have been explored in science fiction, and of course even real-world societies like China have struggled with population control. What do you do when someone breaks one of these rules? We talked about crime and punishment in a previous episode — do you lock up the parents? What do you do with the fetus, who never asked for any of this, but who could pose a threat to the settlement just by being born? Rebecca Kukla: “I mean, there are ethical problems in the sense that coercing or manipulating somebody into an abortion and into that kind of control over their body seems to be, prima facie, unethical. Whether or not you think that abortion is ethical under some circumstances, surely most of us agree that trying to pressure somebody into an abortion or force them into an abortion is always wrong. So I’m concerned that people would be under huge pressure to do away with fetuses who were seen as unsupportable in these new environments, where there weren’t many resources.” And then there’s the opposite problem: What happens when your settlement is underpopulated? In order to become self-sufficient, a settlement has to be able to maintain, and hopefully grow, its population without having to keep shipping in new settlers from Earth. Any dip in the birth rate could mean a severe labor shortage down the line. So how do you maintain a stable population? Mandating reproduction sounds like an even worse idea than mandating birth control. Rebecca Kukla: “In addition to all of the worries around coercion in both directions to do with reproduction itself, there’s a whole other cluster of issues around the fact that the way that we generally reproduce is through sex. So if we’re worried about pressure on people to reproduce, we also need to be worried about pressure on people to consent to sex in the first place. So I think that there’s a whole interesting set of ethical concerns around sexual consent that would come up.” This goes back to something else we talked about in the second episode: when you’re selecting who gets to go live in your space settlement, are you thinking about how those people will reproduce in the future? What does that look like? Do you only bring people who want to have children? Specifically, do you only bring straight people who are interested in having kids the traditional way? Rebecca Kukla: “I mean, there’s a whole temporally prior set of questions around who we pick to do this colonizing in the first place. And if there’s a huge bias in favor of people who are interested in heterosexual reproduction, you’re right that that, along the way, turns into other kinds of biases that we’re not comfortable with. And also, I mean, people’s sexuality is fluid. They may think that they’re interested in heterosexual reproduction. I mean, presumably, we’re gonna be mostly picking young, healthy people to go do this in the first place. And young people’s opinions change, and their desires change. And they may get there and decide that heterosexuality is not for them after all. And even aside from the sexual coercion point, yeah, there’s a real question about whether that would become, you know, a source of resentment or prejudice, not for the usual homophobic reasons but for a whole new set of reasons. Yeah, that’s a real concern. And then of course, you know, when you’re looking at one generation on, then you can’t control who’s there in the same way, but you still have a small colony that presumably is still under enormous pressure to propagate itself. And so there’s a worry that people born into that colony who turn out to be queer or just not interesting hete…

    Ep 06: Who’s in Charge? Dec 20, 2017
    Show notes

    Who will make the decisions in future space settlements? Will they be governed remotely by nations on Earth? Will settlements develop their own local governments? How will conflicts between settlements and with nations back on Earth be resolved? Are we facing a future of war in space? Space lawyers Laura Montgomery and Christopher Newman join us again to talk about how current and future laws might regulate behavior in space. Historian Lauren Benton describes how empires in the past governed their remote colonies. And anthropologist Brian Ferguson discusses the potential for war in space. The transcript for this episode is below. Imagine this: Life is pretty good in space. You just got a promotion at the mining company, and the new restaurant that opened in your section of the habitat makes kebabs that you swear are even better than the ones back on Earth. But things have gotten a little tense around the neighborhood. Everyone’s arguing about the water supply issue. The farmers have been arguing for a bigger share to keep up with demand, but the power plant engineers say they can’t cut their usage without risking outages. Somebody’s going to have to make a decision. But who? Welcome to Making New Worlds, a podcast about the ethical issues involved with settling space. I’m Erika Nesvold. Today we’re asking, who’s going to be in charge of our space settlements? Will they be ruled from a distance by governments back on Earth? Will they have local governments? How will they be structured? How will they deal with conflict, both within the settlement and with other settlements and countries on Earth? Let’s check in with current space law. You might remember from Episode 3 that we talked about the Outer Space Treaty of 1967, which covers things like property ownership and the use of nuclear weapons in space. The relevant part of the Treaty for this episode is Article VI, which says that “The activities of non-governmental entities in outer space… require authorization and continuing supervision by the appropriate State Party to the Treaty.” Non-governmental entities means people like you and me and Elon Musk. Space lawyer Laura Montgomery, who talked to us in Episode 3, points out that no one really agrees what “authorization and continuing supervision” means. Laura Montgomery: “And the question is, is whether that requires a heavy regulatory hand, or nothing, which is my own view, in terms of what the private sector can do under current law.” Laura argues that interpreting Article VI to mean that Earth-based governments should regulate every possible activity that could be done in space would be unnecessarily expensive and overreaching. Laura Montgomery: “And right now, you know, Congress is looking at whether to pass a law requiring that everything you do in space be authorized and supervised. And we have– there was a proposal from the previous administration that would have had everything you did in outer space be authorized and supervised. And, I’m being a little sarcastic here, but I do think that we should first federalize Connecticut and see how that works out before we go and federalize the entire Solar System. So I would rather see a more limited approach than one that just said, “All space activities.” I think that’s biting off more than anyone can chew, and is perhaps a waste of resources, because there’s a whole host of activities that are completely harmless and benign that do not require governmental oversight.” It remains to be seen how the Outer Space Treaty will be interpreted by the courts as more and more activity moves into space in the future. But let’s take a moment to look towards the past. Unless this is your first episode of the podcast, you’ve probably noticed that I like to get a historical perspective on the issues we talk about to see how people handled things in previous generations. For this topic, I talked to historian Lauren Benton. Lauren Benton: “I’m a historian and am the Nelson O. Tyrone, Jr. Professor of History and Professor of Law at Vanderbilt University… I do research on the history of empires, with a special emphasis on European empires, and then also a focus on law in European empires. How it is– was used in the formation of colonies, in interactions with indigenous peoples, and in inter-imperial relations.” I started off by asking how empires governed their remote colonies in the past. Lauren Benton: “It’s difficult to reach broad generalization about this. I can tell you about some of the patterns. It– There are some similarities based on their familiarity with Roman law, for example, as the basis for making claims. They also had a lot of, and relied on a lot of the routines that they used in governance at home, and constituted their settlements as extensions of the realm or in some cases, as– They were all composite polities, that is to say, they were kingdoms made up, in some cases, of many realms, and so it was not that unusual for them to imagine rule of some sort over a distant realm that had different governance. And so they innovated a lot, as they created these systems of rule… It was very interesting in the history of colonization that none of the powers engaging in colonization actually had a very clear-cut constitutional or governance model for how they were going to do this. So really, they were shifting all the time. They would kind of create a certain framework for governance in the colonies and then forces would come to light that would cause those– that framework to need to be adjusted. So, for example, as elites in the colonies got more powerful and wealthier, they would place demands to have greater autonomy and in some cases were successful in changing the very framework of governance for the colonies. And in other cases, they just took more autonomy.” On the one hand, a flexible, adaptable, make-it-up-as-you-go-along approach to government would fit right in with the spirit of the tech culture that’s dominating currently the conversation about corporate space settlement. On the other hand, it could also result in the wealthiest people in a society taking more and more power. Will that be at the expense of the rest of the population? And where does that kind of power shift lead? I’m an American, educated by the American school system, in which the American Revolution is kind of a big deal. Also, I watch and read a lot of science fiction. So when I think about the governments of future space settlements, my thoughts naturally turn to independence. I mean, let’s get to the good stuff, right? When will our imaginary space settlers decide to throw off the yoke of oppression and declare themselves independent from Earth? When I asked my guests a more professional version of that question, however, they poked some holes in my image of a space revolution as inevitable. Here’s Laura Montgomery. Laura Montgomery: “But– could I say something here? At the beginning, when someone goes to Mars, it’s going to probably be a corporation. It is going to be a corporation with its assets on Earth. And if it is doing something that violates actual laws, and, you know, I have a limited view of what the actual laws are, then its assets can be attached, it can be fined, by the government here on– by governments here on Earth. So I think it will be a long time before we see any kind of declarations of independence. But then, it was a long time between Christopher Columbus and 1776, too, so. Time does pass.” Okay, sure, so initially, people living in space will have a lot of reasons for wanting to maintain good relations with Earth. Their assets will still be back on Earth, along with their families, their national identities, not to mention all of the supplies that they’ll need to keep shipping to space until they’re able to become completely self-sufficient, which will likely take generations. Lauren Benton agreed. Lauren Benton: “I’m guessing that space colonies are not going to want to go independent. They’re going to have a lot of incentive not to be independent, right? They’re going to maintain– And really in that way, they will be more similar to overseas colonies where elites really dreamt, very often, of returning home with their fortunes and sending their children back home to be educated and marrying people back home and trading back home.” Lauren pointed out that this idea of independence as the natural and inevitable end goal of colonies is not supported by historical evidence. Lauren Benton: “I actually think it’s a little bit of a– an odd impression that people sometimes have, that independence was the central preoccupation of people in colonies. In a lot of cases, that was not the case, right? They were— there were a lot of worries on the part of European rulers about settlements becoming not so much independent but acting independently. That is, you know, rulers doing things that had not been specifically sanctioned, making up their own foreign policy, these kinds of things. But the worry about breakaway independence was, you know, for a long period of time, I would say, not as important as we might think. Particularly Americans who are focused on the American Revolution tend to view this as the, you know, most central preoccupation of colonies. But after all, the colonies very often depended very much on trade and on– Their elites depended for advancement, for social advancement, and economic advancement, on the home country. They’d look to the monarchs for patronage and so they were referring all the time and writing all the time to the kings to proclaim that they were doing a great job and really should be rewarded for it… It was extremely rare for people to just say, “I’m no longer in the empire. I’m not longer a loyal subject of the king.” This was true even of people we tend to think of as rogue actors in the early modern period, in and around colonies, like pirates. We tend to think of pirates flying the black flag and attacking anybody in sight, but most people who were labeled pirates always were, themselves, very careful to be claiming to act on behalf of a particular sovereign. And sometimes they changed their idea or– they literally changed the flag to indicate that they were acting for one sovereign rather than another, but they very rarely put up the black flag. That was something that happened during a very short period of time. Most people were representing themselves as loyal subjects of some power at all times. That might happen in the future of space colonization. I would think it would happen— be more likely to happen than have people go rogue, because, particularly out in space, with the dependence one would have on supplies and communication and– I don’t think going rogue would be much of an option.” Of course, this doesn’t mean that there will never be conflict between space settlers and governments back on Earth. But history suggests plenty of outlets for that kind of conflict that don’t include taking up arms and designing a new flag. Lauren Benton: “There was a famous phrase in the Spanish empire. In Spanish it is, “Obedezco pero no cumplo.” And that means, “I obey but do not comply.” So there was an interesting game that very often governing elites would play, where they would receive instructions from the home government, the metropolitan government, and they would sort of do what was asked of them, or pretend to do what was being asked of them, but not very effectively, not very quickly. And in some cases they had delaying tactics. And this is something you might see in the future of space colonization. They were very far away, so they could always ask for clarification. So, they would write back and say, “We’re not really sure what you meant by that. Could you give a little more specificity there?” And they knew that it would be months for this message to travel back to Spain or to England or France and then months more for the answer to come back. So just by that very delay, they were gaining a lot of time during which they could do what they wanted.” For the record, now that Lauren has brought it up, I 100% believe that space settlers of the future will pull this trick. It seems like the perfect use of the communications delay that people living beyond the Earth’s orbit will have to deal with. Lauren also discussed another potential source of conflict, aside from disagreements between a settlement and their parent government on Earth. Lauren Benton: “I would put that to one side, and if I could, I would mention another element of strife, which I think might play itself out in the future in space colonization and was very present in the history of colonization. And that is conflict among and between empires for claims to colonies and settlements. That kind of conflict— about which power had the right to settle areas, which power had the right to control trade in and out of particular ports— that kind of conflict was very, very present. And European used certain kinds of conventions for attempting to deal with that conflict, not always successfully. But that was the main focus, I would say, of colonial governance right up until the end of the 18th century.” Given that humanity’s big initial push into space was driven by the Cold War between the U.S. and the Soviet Union, it seems like a safe bet to predict that in the future, conflict will arise between nations on Earth about resources and territory in space. Just because corporations are currently dominating the conversation about space settlement doesn’t mean that governments won’t get back into the game. If the U.S. and China both put colonies on Mars, will tensions between the two countries on Earth extend to space? What about vice versa? War in space is scary to think about, mostly because it’s even easier to kill large groups of people in a fragile environment like a space habitat than it is on Earth. Just cut off their supplies, contaminate their water, poke a big hole in the dome or space station or underground habitat and let all the air out. And the people back on Earth won’t be much safer if war moves into space. Before you even start worrying about nukes or giant lasers, remember that a space rock wiped out the dinosaurs. Someone in space who wanted to attack a city on Earth could literally just drop a rock on it. So is this our future? Is war in space inevitable? Brian Ferguson: “People tend to think that we’re always going to have war, even war in outer space. And one of the reasons they think that is they think that war is inevitable, it’s in our nature. And they think it’s in our nature in part because they think that humans have always made war.” This is Brian Ferguson, professor of anthropology of Rutgers University Newark, who studies the anthropology of war. Brian Ferguson: “This has been a lot of my research over recent years. And although you will find many people who argue that the archaeological record suggests that we find war everywhere we look in the past, I can tell you quite definitely that that is not the case. People who seem to find everywhere they look are looking at cases where war is present… What’s very interesting, I think, is that you see some places where all the preconditions would seem to indicate war is going to be present, and yet war is not present in the archaeological record. For instance, I have written about an area called the Southern Levant, which is the Mediterranean, the eastern Mediterranean coast area that’s wracked by war now. And the incredible thing, I believe, is that from 13,000 BC to 3,200 BC, there is not one single place where you can say that war was present. There’s a couple of suspected places, but nothing that’s definite. And in other parts of the world, definite evidence is abundant. And what I think you can discern there is that those people, the people who domesticated plants and animals, also found ways to domesticate conflict. Conflict always exists. It will always exist. But there are violent…
