Recreating Mars as a Watery World
In a former mining town in Colorado, a geophysicist maps water, and possible sites of ancient life, on the Red Planet

At the Colorado School of Mines, Jeffrey C. Andrews-Hanna, an assistant professor of geophysics, models the way water sculpted Martian surfaces such as the one shown on his computer.
In December, when scientists running a Mars rover announced that the robot had found a tiny rock that was the most "bulletproof observation" of Martian water, they weren't the only ones with satisfied grins. The rock, nicknamed Homestake, appears to be the result of a crack from which water once bubbled out of the ground, and is "absolutely exciting," says Jeffrey C. Andrews-Hanna. He had predicted it would be there, using a model of Mars that he built on a computer.
