10 Good Reasons Not to Colonize Mars Robert Walker , Science 2.0 August 15, 2013 Mars is a fascinating planet, the most like Earth of all the planets in the solar system, and may help us to understand much about the origins of life on Earth. Believe it or not, that’s great news. Humans Should Not Colonize Mars - Volume 3 Issue 3. You read that right. When it comes to terraforming Mars, there’s also the logistics to consider, and the materials available to the geoengineers who would dare to embark upon such a multi-generational project. Pioneering astronautics engineer Louis Friedman, co-founder of the Planetary Society and author of Human Spaceflight: From Mars to the Stars, likens this unfounded enthusiasm to the unfulfilled visions proposed during the 1940s and 1950s. Seidler said some of these changes scale with the duration of microgravity exposure, from two weeks up to six months, but she hasn’t looked beyond that. The thin atmosphere also means that heat cannot be retained at the surface. The low gravity may also “confuse” the gestational process, delaying or interfering with critical phases of the fetus’ development, such as the fetus dropping by week 39. Horgan pointed to a recent Nature study showing that radiation on Mars is far worse than we thought, adding that “we don’t have the long-term solutions yet, unless you want to risk radiation illnesses.” Depending on the degree of exposure, excessive radiation can result in skin burns, radiation sickness, cancer, and cardiovascular disease. Briony Horgan, assistant professor of planetary science at Purdue University, said Martian terraforming is a pipedream, a prospect that’s “way beyond any kind of technology we’re going to have any time soon,” she told Gizmodo. Astronauts who return from long-duration missions have a rough go for the first few days back on Earth, experiencing nausea, dizziness, and weakness. The red planet is no place for flags and nationalism. A common argument in favor of colonizing Mars is that it’ll allow us to begin the process of transforming the planet to a habitable state. Elon Musk (born in 1971) of SpaceX says he wants to die on Mars—but not on impact. Excellent article and worthy of discussion and serious thought. The suggestion that humans will soon set up bustling, long-lasting colonies on Mars is something many of us take for granted. Even though this is all true the rejecting side has claims that outweigh these reasons to go. To beat COVID-19, we need a global vaccination effort. It can ‘learn’ how to control movements in microgravity despite the altered sensory inputs. “It’s not clear whether these changes would plateau at some point. For the Moon, there is the Google Lunar X prize, Shackleton Energy Corp, and OpenLuna, and again numerous other groups. This scenario has been tackled by a number of science fiction authors, including Kim Stanley Robinson in his acclaimed Mars Trilogy. That we may eventually become an interplanetary or interstellar species remains an open question. The … The average temperature on Mars is -81 degrees Fahrenheit (-63 degrees Celsius), with temperatures dropping as low as -195 degrees F (-126 degrees C). But don’t ever expect mass emigration from Earth. “Some of these effects would have to eventually plateau—there is a structural limit on the fluid volume that the skull can contain, for example,” she said. If humans can’t make it to Mars, it means we’re destined to be “a single-planet species,” he said. But again, nothing that we could possibly develop soon. There’s no ‘Planet B’ for ordinary risk-averse people. After the Moon landings, Friedman said he and his colleagues were hugely optimistic about the future, believing “we would do more and more things, such as place colonies on Mars and the Moon,” but the “fact is, no human spaceflight program, whether Apollo, the Space Shuttle Program, or the International Space Station,” has established the necessary groundwork for setting up colonies on Mars, such as building the required infrastructure, finding safe and viable ways of sourcing food and water, mitigating the deleterious effects of radiation and low gravity, among other issues. Indeed, modifying humans to make them adaptable to living on Mars will require dramatic changes. The arguments above show that we are perhaps not ready to go to Mars – at least, not today. A possible solution is to radically modify human biology to make Martian colonists specially adapted to live, work, and procreate on the Red Planet. “People don’t realize how complicated this is,” said Horgan. Sadly, this is literally science fiction. On Earth, bones, muscles, the circulatory system, and other aspects of human physiology develop by working against gravity. But space is a spectacularly awful place…. Endless expansion is not possible, and we’re about to realize that painfully. Jakosky and Edwards concluded that there’s not nearly enough CO2 on Mars required for terraforming, and that future geoengineers would have to somehow import the required gases to do so. By post-human future, Rees is referring to a hypothetical future era in which humans have undergone extensive biological and cybernetic modifications such that they can no longer be classified as human. Turns out the moon is an even harsher mistress than we all thought. And these are the health issues we think might be a problem. 0. Genetic modification would be supplemented by cyborg technology—indeed there may be a transition to fully inorganic intelligences. Life in this closed environment, with limited access to the surface, could result in other health issues related to exclusive indoor living, such as depression, boredom from lack of stimulus, an inability to concentrate, poor eyesight, and high blood pressure—not to mention a complete disconnect from nature. … They would carry with them their earthly microbes. Humanity's eventual journey through interplanetary space and landing on Mars won't be about winning; it will be about progress. Unlike other fields, development into human spaceflight, he said, “has become static.” Friedman agreed that we’ll likely build bases on Mars, but the “evidence of history” suggests colonization is unlikely for the foreseeable future. “But this just hasn’t happened. Are we facing an ‘Insect Apocalypse’ caused by ‘intensive, industrial’ farming and agricultural chemicals? But as Friedman told Gizmodo, “that’s thousands of years in the making at least.”. Posted by 10 hours ago. This article or excerpt is included in the GLP’s daily curated selection of ideologically diverse news, opinion and analysis of biotechnology innovation. Why do you think there are so many conversations about Martian colonization? We’re gonna colonize Mars. But she says Mars is not a good place for living for the long term. How is that going? Podcast: Unreliable COVID tests; Amazon’s creepy Halo health band; Celebrate pesticides? Secondly, This would cost lots of money, And we could spend money on better things such as fixing our Earth, Which leads to my third point, That we should fix our Earth first … Horgan said there are many big challenges to colonizing Mars, with radiation exposure being one of them. A few more reasons why we shouldn’t move to Mars include the facts that it’s too cold for us to survive without an abundance of extremely reliable technology, the atmosphere is so thin it counts as a laboratory vacuum on Earth, there are rough and global dust storms and much more, according to Scientist Robert Walker. And of course, if we have not figured out how to deal with problems of our own making here on Earth, there is no guarantee that the same fate would not befall Mars colonists. This will require specialized lighting, genetically modified plants designed specifically for Mars, and plenty of water, the latter of which will be difficult to source on Mars. By contrast, the coldest temperature ever recorded on Earth was at Vostok Station in Antarctica, at -128 degrees F (-89 degrees C) on June 23, 1982. This might be the first step towards divergence into a new species. While delivering a keynote address at a NASA event in 2010, Venter said, “Not too many things excite my imagination as trying to design organisms—even people—for long-term space flight, and perhaps colonization of other worlds.”. This article offers two arguments for the conclusion that we should refuse on moral grounds to establish a human presence on the surface of Mars. This GLP project maps contributions by foundations to anti-biotech activists and compares it to pro-GMO industry spending. That said, colonizing Mars would be a significant achievement if done correctly. But again, it’s unclear what the upper limits are.”. With this in mind, it’s an open question as to how Martian colonists might fare upon a return visit to Earth. Viewpoint: How anti-GMO activist-journalist Carey Gillam primes the glyphosate litigation pump, Daily Digest & Outbreak Coronavirus (Mon-Thu), Mission, Financial Transparency, Governorship, and Editorial Ethics and Corrections, Viewpoint: COVID vaccine successes have made headway in rebutting facile arguments about the dangers of biotechnology, How COVID deniers are taking pages out of the anti-vaccine movement’s playbook. Humans once stepped on the lunar surface, but never Mars. How come Elon Musk is so obsessed with Mars? Known by some as the "Environmental Worrying Group," EWG lobbies ... Michael K. Hansen (born 1956) is thought by critics to be ... News on human & agricultural genetics and biotechnology delivered to your inbox. Right now, you are standing on the edge of history. “Yes, there would be physiological and neural changes that would occur on Mars due to its partial-gravity environment,” she told Gizmodo. Robots have several inherent advantages. Which brings a rather discouraging prospect to mind: We may be stuck on Earth. An artificial womb might be a possible solution, but again, that’s not something we’ll have access to anytime soon, nor does it solve the low-gravity issue as it pertains to fetal development (unless the artificial womb is placed in a centrifuge to simulate gravity). The main reason is radiation. There are also those who think that even if we can colonize other planets we shouldn't for a variety of reasons, either ethical, political, or social. They just want to be the first people on a new planet. And it may not even happen. Another issue has to do with motivation. “A lot of people approach it as thinking we shouldn’t limit ourselves based on practicalities, but I agree, there are a lot of potential negative physiological consequences.”. Which is a good point. Our interactive GLP global map explains the status of each country’s regulations for human and agricultural gene editing and gene drives. “You can only do so much with radiation protection,” Horgan said. Technological solutions to these problems may exist, as are medical interventions to treat Martian-specific diseases. More or less deadly? This can result in a poor sense of balance and compromised motor functions, but research suggests astronauts in microgravity eventually adapt. Colonists will also need stable food sources, and figure out a way to keep plants away from radiation. Space X wants to use the moon as a launching area for spaceships to Mars. It’s a dangerous delusion to think that space offers an escape from Earth’s problems. Seidler, an expert in human physiology and kinesiology, said the issue of human gestation on Mars is a troublesome unknown. We must colonize Mars to mitigate existential threats to humanity as a species. Organic v conventional using GMOs: Which is the more sustainable farming? Mars also has less mass than is typically appreciated. If that's your motivation, then remember, as soon as the first colonists arrive on Mars then it will already "be done". It might actually be a brutal experience, especially after having experienced years in a partial gravity environment. These traits could be made heritable, such that Martian colonists could pass down the characteristics to their offspring. Hendrix is actually not too negative about Mars. We don’t know how sperm and egg will act on Mars, or how the first critical stages of conception will occur. And that’s assuming humans could even reproduce on Mars, which is an open question. Indeed, there’s the whole terraforming issue to consider. By terraforming, scientists are referring to the hypothetical prospect of geoengineering a planet to make it habitable for humans and other life. But, we won’t know if a permanent presence is possible until we try. My work has shown an upward shift of the brain within the skull in microgravity, some regions of gray matter increases and others that decrease, structural changes within the brain’s white matter, and fluid shifts towards the top of the head.”. In the second instalment of his two-part feature on human missions to Mars, Dr Alexander Kumar asks whether we should send people to the Red Planet given our poor record managing this one. A host of other problems are likely to exist, giving rise to Martian-specific diseases affecting our brains, bodies, and emotional well-being. This leads Nick Bostrom to argue that failing to colonize space would be tragic because it would mean that these potential “worthwhile lives” would never exist, and this would be morally bad. Many people agree that we should go to mars but I disagree. Please support us – a donation of as little as $10 a month helps support our vital myth-busting efforts. This is an “issue that a lot of folks, including those at SpaceX, aren’t thinking about too clearly,” she told Gizmodo. Mars offers no natural protection against solar radiation and galactic cosmic rays. George is a senior staff reporter at Gizmodo. No place in our solar system offers an environment even as clement as the Antarctic or the top of Everest. While there’s no doubt in my mind that humans will eventually visit Mars and even build a base or two, the notion that we’ll soon set up colonies inhabited by hundreds or thousands of people is pure nonsense, and an unmitigated denial of the tremendous challenges posed by such a prospect. We’ve got to solve these problems here. This is why Mars can benefit us. More needs to be done.”. Mars is the best target for colonization in the solar system because it has by far the greatest potential for self-sufficiency. When the the first Apollo mission landed on the moon they only had 30 seconds of fuel left, 30 SECONDS! She only provides us with a limited amount of resources, and we are burning through them at an enormous rate. Limited access to fundamental resources, like food and water, could place further constraints on a colony’s ability to grow and thrive. Nanotechnology in the form of molecular machines could deliver medicines, perform repair work, and eliminate the need for breathing and eating. Work by NASA’s Scott Wood has shown that recovery time for astronauts is proportionate to the length of the mission—the longer the mission, the longer the recovery. We should wish them good luck in modifying their progeny to adapt to alien environments. Earthrise, 1968. Unless we radically adapt our brains and bodies to the harsh Martian environment, the Red Planet will forever remain off limits to humans. Populations of people have a tenancy to ruin the places we go to. Unless we radically adapt our brains and bodies to the harsh Martian environment, the Red Planet will forever remain off limits to humans. So, it’s these space-faring adventurers, not those of us comfortably adapted to life on Earth, who will spearhead the posthuman era. “It is really because we have an innate desire to explore.” The problem is that you can’t stay in there [i.e. Close. ... Mars is even more expensive, and we aren't likely to get the funds back directly. Yet despite these and a plethora of other issues, there’s this popular idea floating around that we’ll soon be able to set up colonies on Mars with ease. All of which suggests that the problem is "more of an issue for colonization outside of the solar system." This idea that we are going to abandon Earth and go live on Mars … The suggestion that humans will soon set up bustling, long-lasting colonies on Mars is something many of us take for granted. Until such time, an un-terraformed Mars will present a hostile setting for venturing pioneers. To Understand Earth: Mars is the planet in our solar system that is most similar to Earth. Read full, original post: The case against Mars colonization. The paltry amount of air that does exist on Mars is primarily composed of noxious carbon dioxide, which does little to protect the surface from the Sun’s harmful rays. 1. We must slow down global warming and reverse it back, if possible. They’ll harness the super-powerful genetic and cyborg technologies that will be developed in coming decades. Seidler’s research into the effects of microgravity suggests it’s a distinct possibility. Air pressure on Mars is very low; at 600 Pascals, it’s only about 0.6 percent that of Earth. Saturn’s largest moon Titan is the only natural satellite with more than a trace atmosphere. Within a few years, Mars will be a suitable place to live. “But it also sounds a bit pie-in-the-sky,” she said. [T]he first argument against human travel to Mars: contamination. Seidler said NASA and other space agencies are currently working very hard to create and test countermeasures for the various negative impacts of living on Mars. In a few centuries or less humans will likely still exist, but the technological society we’ve built for ourselves will be gone and something vastly different will have replaced it. Like some of the other solutions proposed, this won’t happen any time soon, nor will it be easy. Perhaps after five or 10 or 20 years of constant exposure to low gravity, similar gravity-related disorders will set in. Firstly, It is dangerous to fly there, Especially with young families. What reasons do we have to invest the resources required to establish a human presence on Mars? But the further north you go, the rougher the conditions get on the surface. An experiment that had vast possibilities but has the fatal flaw of hubris. I googled it, and I didn't find anything about the topic, so I came here. A strong case can be made that any attempt to procreate on Mars should be forbidden until more is known. underground or in bases] forever. Once temperatures get below the -40 degrees F/C mark, people who aren’t properly dressed for the occasion can expect hypothermia to set in within about five to seven minutes. As soon as you go outside to do anything, you’re in trouble,” she said. They are much cheaper than humans because they don’t require a vast support infrastructure to provide things like water, food and breathable air. The effects of living in partial gravity compared to microgravity may not be as severe, she said, but in either case, different sensory inputs are going into the brain, as they’re not loaded by weight in the way they’re used to. Is there a Bible passage that justifies why we SHOULDN'T colonize or terraform Mars? It’s possible that the human body might adapt to the low-gravity situation on Mars, but we simply don’t know. Are most GMO safety studies funded by industry? We shouldn't colonize Mars. And most of all, we don’t know how low gravity will affect the mother and fetus. While that might sound appealing, this low-gravity environment would likely wreak havoc to human health in the long term, and possibly have negative impacts on human fertility. Mars’ gravity is less than Earth but large enough to lure gases and form an atmosphere. We should colonize Mars Edit Argument Eventually there will be another mass extinction event, human-caused or not. As Friedman pointed out, this carries some rather heavy existential and philosophical implications. Preliminary: Why should we colonize Mars? I identify five reasons offered by advocates of colonization… Even if Mars is a lifeless planet, whether it’s ethical to colonize Mars may depend on what kinds of consequences the mission has here on Earth. She thinks we should go there, visit the planet and do science there. Mars is the easiest planet for Earthlings to reach, but it isn’t exactly easy to get there. You might as well be exposed to the vacuum of space, resulting in a severe form of the bends—including ruptured lungs, dangerously swollen skin and body tissue, and ultimately death. The regolith, or soil, on Mars is toxic, containing dangerous perchlorate chemicals, so that also needs to be avoided. So while Mars will remain inaccessible to ordinary, run-of-the-mill Homo sapiens, the Red Planet could become available to those who dare to modify themselves and their progeny. Friedman agrees that, in principle, we could create artificial environments on Mars, whether by building domes or underground dwellings. Of course, one easy way to minimise the risk of contamination is to send robots to Mars instead of humans – the second argument against a manned trip to Mars. I suspect that AI and robotic development will reach the point that by the time we can send and return a few people to Mars, we can send indestructible “human-like” robots that can accomplish the same things (and more) on a Mars mission that a real human could do, but without the life-sustaining needs and fragility of humans. We must work to make this futuristic prospect a reality, but until then, we have to make sure that Earth—the only habitable planet we know of—remains that way. The radiation problem may be solvable, he said, “but the problems are still huge, and in a sense anti-human.”. Disaster interrupted: Which farming system better preserves insect populations: Organic or conventional? Not only does it not support life, but it turns out those charming craters aren’t just lovable scars from millions of years ago. The human lifespan on Mars is likely to be significantly less than it is on Earth, though again, we simply don’t know. Well, progress and parades. “Back then, cover stories of magazines like Popular Mechanics and Popular Science showed colonies under the oceans and in the Antarctic,” Friedman told Gizmodo. Gravity on the Red Planet is 0.375 that of Earth’s, which means a 180-pound person on Earth would weigh a scant 68 pounds on Mars. Coping with climate change may seem daunting, but it’s a doddle compared to terraforming Mars. The developing fetus, she said, is likely to sit higher up in the womb owing to the lower gravity, which will press upon the mother’s diaphragm, making it hard for the mother to breathe. First and foremost there’s the intense radiation to deal with, which will confront the colonists with a constant health burden. These goods can be fairly limited in m… Nobody owns Mars, because Mars is the common inheritance of all humankind. Sometime soon, something’s gonna happen that will send you tumbling over into a whole new era of human evolution. The notion that we’ll soon set up colonies inhabited by hundreds or thousands of people is pure nonsense. Neuroscientist Rachael Seidler from the University of Florida says many people today fail to appreciate how difficult it’ll be to sustain colonies on the Red Planet. For Mars, that would mean the injection of oxygen and other gases into the atmosphere to raise surface temperature and air pressure, among other interventions. What’s more, it suggests extraterrestrial civilizations might be in the same boat, and that the potential for “intelligent life to spread throughout the universe is very, very gloomy,” he told Gizmodo. I know, it's a weird question, but as technology improves, it's bound to come up sooner or later. So why aren’t we racing to colonize the moon? “If we can’t make it to a nearby planet with an atmosphere, water, and a stable surface—which in principle suggests we could do it—then certainly we’re not going to make it much beyond that,” said Friedman. Have we lost hope for Earth? Life in a Martian colony would be miserable, with people forced to live in artificially lit underground bases, or in thickly protected surface stations with severely minimized access to the outdoors. As Martin Rees pointed out, Mars and other space environments are “inherently hostile for humans,” but as he wrote in his book. To grow crops, colonists will likely build subterranean hydroponic greenhouses. And like the International Space Station, Martian habitats will likely be a microbial desert, hosting only a tiny sample of the bacteria needed to maintain a healthy human microbiome. As Friedman pointed out earlier, we don’t see colonists living in Antarctica or under the sea, so why should we expect troves of people to want to live in a place that’s considerably more unpleasant? To inform the public about what’s really going on, we present the facts and challenge those who don't. “Trying to think about establishing colonies to point of what we would consider safe will be a big challenge.”. “We could quantify the risks for about a year, but not over the super long term. Podcast: Beyond CRISPR and gene therapy—How ‘gene writing’ is poised to transform the treatment of even the rarest diseases, Podcast: Polymerase chain reaction—The ‘transformative’ tool that sparked a genetics revolution, Video: Infrared camera shows how COVID spreads through a room. Disturbingly, we have no data for microgravity exposure beyond a year or so, and it’s an open question as to the effects of low gravity on the human body after years, or even decades, of exposure. To be clear, terraforming is not necessarily an impossibility, but the timeframes and technologies required preclude the possibility of sustaining large, vibrant colonies on Mars for the foreseeable future. There are many reasons why we shouldn’t go like, it is too expensive, and that it is very dangerous. The notion that we can start colonizing Mars within the next 10 years or so is an overoptimistic, delusory idea that falls just short of being a joke. In fact, not at all, despite the relative ease at which we could achieve this. But many explorers who want to colonize Mars have as their main motivation that it is new. Collectively, these changes would result in an entirely new species of human—one built specifically for Mars. No, vaccines are not harmful. In the interim billions will die.
