We’re on Mars!

I love this picture. We so totally have robots that drive around on Mars and take pictures of things:

Turns out that NASA has found the most convincing evidence yet of liquid water there:

…unveiled this week at the American Geophysical Union conference in San Francisco, is a thin vein of gypsum laced inside and protruding from an ancient rock along the rim of a 96-mile wide crater called Endeavour.

Gypsum — commonly known as plaster of Paris — typically forms from water flowing through rock.

“This is the single most bullet-proof observation that I can think of that we’ve made this entire mission,” Cornell University planetary scientist Steve Squyres, lead researcher for NASA’s Spirit and Opportunity Mars rovers, told Reuters.
