The Real Waters of Mars

MSNBC has an interesting article talking about three different studies on Martian water, what it might have looked like when Mars had a hydrological cycle, and what might have happened to it (newest/best theory at the moment; a lack of magnetic fields allowed the solar wind to blow away the Martian atmosphere, leading to cooling and the water being collected as ice at the poles). What really tugged at my gamer’s heart, though, was this terrific map of what Mars would have looked like, based on its topography, with an enormous ocean covering much of the northern hemisphere. I can definitely see that as a game map!
