Mars Rover Opportunity Suffers Worrying Bouts of 'Amnesia'

Inevitable age-related issues have surfaced for Mars rover Opportunity and mission engineers are being challenged by an increasingly troubling bout of flash memory glitches.

NASA's Mars Exploration Rover Opportunity captured this scene looking farther southward just after completing a southward drive, in reverse, during the 3,749th Martian day, or sol, of the rover's work on Mars (Aug. 10, 2014). | NASA/JPL-Caltech
This view is from Opportunity's front hazard avoidance camera on Nov. 26, 2014, during the 3,854th Martian day, or sol, of the rover's work on Mars. The scene includes Opportunity's robotic arm, called the "instrument deployment device," at upper left. Portions of the pale bedrock exposed on the ground in front of the rover are within the arm's reach. Researchers used instruments on the arm to examine a target called "Calera" on this patch of bedrock. The wheel tracks in the scene are from the drive - in reverse - to this location, a drive of 32.5 feet (9.9 meters) on Sol 3846 (Nov. 18, 2014). | NASA/JPL-Caltech
