Ice on Mars! Bears in the Woods!

Er, we've known that Mars has bazillions of tons of relatively pure frozen water for a couple of decades now -- the whole north polar cap, and some of the southern too.

It's cool to see a patch of ice like that a little south of the polar cap, but there's nothing new here in terms of whether Mars has accessible resources or not. We *know* it has all the water ice any colonists will ever need, so long as they don't mind transporting it some distance or building a hab near the pole in the first place.

In terms of *liquid* water, this "lake" also says nothing-- it's frozen all the time, and you don't need it ever to have been liquid to get there in the first place. Atmospheric transport of water vapor works just fine.

But still a pretty picture!
