WAS ANCIENT MARS HABITABLE?

CURIOSITY SELF-PORTRAIT: Goddard scientists search for methane and other organics on Mars with the Curiosity rover, the most powerful lander ever to operate on the surface of Mars.

Mars' signature color (red) originates in a cover of rust, a deep layer of dusty iron-oxide covering much of its surface. Mars is also blanketed with many other minerals including some that formed in water, indicative of a wet past.
