How long would it take to terraform mars: timelines, tech, and challenges
Terraforming Mars is a monumental project expected to take centuries, possibly thousands of years, due to its fundamental challenges: a thin atmosphere, extreme cold, and relentless radiation. Early warming efforts could occur within a century, but creating a breathable biosphere would take millennia. Ethical dilemmas arise about altering Martian conditions and the risk of destroying any existing life.
