Multiple technical barriers make successful colonization impossible

Few people shape our perceptions of the future like Elon Musk. Through companies like SpaceX and Tesla, he’s presented an optimistic vision for the technologies of tomorrow and endeared himself to millions. Out of all his stated goals, one stands out in particular– creating a permanent base on Mars. Musk appears to care deeply about this. He’s regularly discussed his goals with the media, spoke at the Mars Society conference in 2020, and even said in 2014 that his purpose behind creating SpaceX was to develop technologies necessary for “a self-sustaining, permanent base on Mars.” The idea is a central part of his brand of futurism, and it’s easily his most ambitious proposal. However, those goals fall apart when faced with reality. Creating a Martian colony would be highly challenging and unnecessarily expensive. To discuss why let’s start with an obvious factor: space is big. On average, Mars is 140 million miles away from Earth, a distance that takes light and radio signals over 12 minutes to cover. Under ideal circumstances, rockets take nine long months to complete this journey. However, even that ideal transfer window only occurs for 30 days every 26 months. Outside that window, rockets need substantially reduced payloads to allow for higher fuel loads. For a permanent settlement, this is highly impractical. We also have to consider the substantial environmental and health risks of living on Mars. The thin atmosphere and extremely low temperatures would require expensive and complex life support systems. The Martian soil is toxic and unsuitable for crop growth, and the low surface gravity would have major long-term effects on colonists’ bodies. Perhaps the biggest hazard on Mars is radiation. Without the Earth’s magnetic field or ozone layer to protect them, Martian colonists would be exposed to dangerous cosmic rays, substantially increasing cancer risks. Admittedly, radiation doses could be lessened by building shelters underground with few or no windows. However, confining stressed colonists to cramped quarters that are isolated from almost all of humanity could cause the colonists mental strain. Combined with the difficulties of maintaining the colony, psychological breakdowns would be inevitable for the colonists. In Antarctica, researchers enduring the continent’s brutal winters often develop “winter-over syndrome,” with symptoms including depression, insomnia, irritability, difficulty concentrating, and aggression. Even then, Antarctica has a breathable atmosphere and relative proximity to civilization. Mars lacks both, so living there would be even more miserable.
