For one, the Moon lacks an atmosphere to protect … The thin atmosphere also means that heat cannot be retained at the surface. 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. For the Moon, there is the Google Lunar X prize, Shackleton Energy Corp, and OpenLuna, and again numerous other groups. They are much cheaper than humans because they don’t require a vast support infrastructure to provide things like water, food and breathable air. Finally, there’s the day-to-day survival to consider. It seems a poor alternative to living on Earth, and certainly a major step down in terms of quality of life. Excellent article and worthy of discussion and serious thought. The human lifespan on Mars is likely to be significantly less than it is on Earth, though again, we simply don’t know. live 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. I know, it's a weird question, but as technology improves, it's bound to come up sooner or later. As Martin Rees pointed out, Mars and other space environments are “inherently hostile for humans,” but as he wrote in his book. Populations of people have a tenancy to ruin the places we go to. With this in mind, it’s an open question as to how Martian colonists might fare upon a return visit to Earth. It’s possible that the human body might adapt to the low-gravity situation on Mars, but we simply don’t know. “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. What reasons do we have to invest the resources required to establish a human presence on Mars? “Establishing stable resources to live off for a long period of time is possible, but it’ll be tough,” said Horgan. 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. 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. Colonists will also need stable food sources, and figure out a way to keep plants away from radiation. The problem is that you can’t stay in there [i.e. The suggestion that humans will soon set up bustling, long-lasting colonies on Mars is something many of us take for granted. 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. 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. Unless we radically adapt our brains and bodies to the harsh Martian environment, the Red Planet will forever remain off limits to humans. 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? She thinks we should go there, visit the planet and do science there. “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.”. That said, colonizing Mars would be a significant achievement if done correctly. “People like to be optimistic about the idea of colonizing Mars,” Seidler, a specialist in motor learning and the effects of microgravity on astronauts, told Gizmodo. No place in our solar system offers an environment even as clement as the Antarctic or the top of Everest. This might be the first step towards divergence into a new species. But as Friedman told Gizmodo, “that’s thousands of years in the making at least.”. Podcast: Unreliable COVID tests; Amazon’s creepy Halo health band; Celebrate pesticides? underground or in bases] forever. The suggestion that humans will soon set up bustling, long-lasting colonies on Mars is something many of us take for granted. Here we outline some of these perspectives. SpaceX CEO Elon Musk is projecting colonies on Mars as early as the 2050s, while astrobiologist Lewis Darnell, a professor at the University of Westminster, has offered a more modest estimate, saying it’ll be about 50 to 100 years before “substantial numbers of people have moved to Mars to live in self-sustaining towns.” The United Arab Emirates is aiming to build a Martian city of 600,000 occupants by 2117, in one of the more ambitious visions of the future. Like some of the other solutions proposed, this won’t happen any time soon, nor will it be easy. We must slow down global warming and reverse it back, if possible. [We] (and our progeny here on Earth) should cheer on the brave space adventurers, because they will have a pivotal role in spearheading the post-human future and determining what happens in the twenty-second century and beyond. For example, astronauts on the ISS, who are subject to tremendous muscle and bone loss, try to counteract the effects by doing strength and aerobic training while up in space. 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. More needs to be done.”. 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. Nevertheless, even with optimistic extrapolation of robotic manufacturing techniques, Mars will not have the division of labor required to make it fully self-sufficient until its population numbers in the millions. 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. 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. A strong case could even be made that, for prospective families hoping to spawn future generations of Martian colonists, it’s borderline cruelty.
