Curiosity is currently using the B-side computer, which is safe to use and operating as expected. The rover is back on track with assessment and recovery from a memory issue that only affected the rover’s A-side computer. On Feb. 28, the rover’s A-side was switched to the B-side due to symptoms of a corrupted memory location. This switch put the rover in minimal-activity safe mode. On Saturday, March 2, Curiosity resumed using its high-gain antenna. "These tests have provided us with a great deal of information about the rover's A-side memory," said Jim Erickson, deputy project manager for the Mars Science Laboratory/Curiosity mission at NASA's Jet Propulsion Laboratory, Pasadena, Calif. "We have been able to store new data in many of the memory locations previously affected and believe more runs will demonstrate more memory is available." The cause for the A-side's memory symptoms remains to be determined.
