Wind, not water, likely created Mars' Mount Sharp, according to a new study by Princeton University scientists. The 3.4-mile-high mountain will be explored by NASA's Curiosity rover to test the theory.

"Our work doesn't preclude the existence of lakes in Gale Crater, but suggests that the bulk of the material in Mount Sharp was deposited largely by the wind," said study co-author Kevin Lewis.
