More Evidence That Mars Once Had Flowing Water

At this point, though, one thing we’re sure about is the presence of lots of water on Mars. A lot of it is still there in the form of ice in the polar caps and under the surface at mid- to high latitudes. It seems clear it once flowed on and under the surface as well. It really makes me wonder if water could flow under the surface even today. It’s unlikely; you need a heat source, and Mars looks pretty lean in that category these days. Still, Mars is a surprising place, and no doubt has plenty of surprises left for us to find.
