We know that Mars once had lots of water, considered a prerequisite for habitability. What hasn't been known, however, is just how friendly — or unfriendly — this water might have been to life, as the temperature and chemical conditions of ancient Martian water has remained a complete mystery. But as a new analysis of Martian meteorites has revealed water temperatures on the Red Planet once ranged between 50°C to 150°C (122°F to 302°F) — temperatures that we know are most certainly hospitable to microbial life.
