π΄ Mars: Not Quite Earth's Next Home Yet
Mars is often eyed for human colonization, but several harsh realities challenge these big plans. Giant dust storms can circle the planet, blocking 99% of sunlight and damaging equipment, as seen with the Opportunity rover in 2018. The lack of a magnetosphere means humans face high radiation risks from solar flares and cosmic rays. Martian dust is highly abrasive and contains toxic perchlorates, posing health threats inside habitats. Furthermore, at only 38% of Earth's gravity, long-term human health is a major concern, alongside extreme temperature swings.
