This month, NASA's Mars Exploration Rovers mark two years on the red planet.
Spirit and Opportunity continue to find new variations of bedrock in areas they are exploring on
opposite sides of Mars. JPL designed, built and manage the rovers.

This narrated slide show features images selected by the rover team.
