Scientists Discover the First Large Body of Liquid Water on Mars

Might be more accurate to say that the European Mars Express orbiter has found evidence (via radar) of water *in* Mars, a subsurface lake  beneath the polar ice cap that is 12 miles across and several feet thick… and about a mile below the surface. With no geothermal warming of any consequence, it doesn’t make a whole lot of sense for thee to be sub-ice cap water, but the researchers think that the water is probably saturated with various salts that lower the freezing point.
