Scarecrow Rover Wheel Closeup

On June 24, 2014, NASA's Curiosity rover completes her first Martian year (687 Earth days).

This oblique view of Gale Crater shows the landing site and the mound of layered rocks that NASA's Mars Science Laboratory will investigate. The landing site is in the smooth area in front of the m...

NASA's Mars Science Laboratory, a mobile robot for investigating Mars' past or present ability to sustain microbial life, is in development for a launch opportunity in 2009.

This diagram illustrates Mars' "thermal tides," a weather phenomenon responsible for large, daily variations in pressure at the Martian surface.
