Learn About Space Colonization

Plan humanity's future beyond Earth — Mars habitats, O'Neill cylinders, terraforming, space agriculture, radiation shielding, and the monumental challenges of becoming a multiplanetary species.

Gerard O'Neill's 1976 book "The High Frontier" proposed massive rotating space habitats at the L5 Lagrange point that could house millions of people using lunar and asteroid materials, and his ideas continue to influence space colonization planning at companies like Blue Origin. SpaceX's Starship, designed to carry up to 100 passengers to Mars, represents the first vehicle explicitly designed for interplanetary colonization, with Elon Musk's stated goal of establishing a self-sustaining Mars city of one million people. The major biological challenges include cosmic radiation (Mars settlers would receive roughly 0.67 millisieverts per day, compared to 0.01 on Earth), bone density loss of 1-2% per month in microgravity, and the psychological effects of isolation — the Mars-500 experiment locked six volunteers in a simulated Mars habitat for 520 days (2010-2011) to study long-duration confinement effects.
