I find it fascinating that even the possibility of water existing on Mars was almost a foolish thought — just a few years ago even.
And now, here we are with an image of a 51 mile wide crater full of ice. Truly an amazing time to be a fan of space exploration!
stupid question: why aren't we dropping landers on ice-filled craters on mars? it seems like that would be a much more productive way to collect interesting samples than landing on rock.
No indication in the article of what makes it water ice.
