MARS OPPORTUNITY ROVER HAS MEMORY PROBLEM

The Mars Opportunity rover has covered 26 miles since it landed on the Martian surface ten years ago. During that time it has gathered and sent back vital data. However, recent reports from Nasa indicate that Opportunity has developed a problem with the memory of its on-board computer:

Project manager John Callas explained that when Opportunity tries to save telemetry data to its flash memory (equivalent to a computer's hard drive) it fails, so it then writes it to the volatile memory (like a computer's RAM) instead, which gets wiped when the rover powers down. The problem has become more severe, with Opportunity resetting itself, and sometimes stopping communication with mission control altogether.

A solution is being attempted so the rover software ignores the faulty part of the flash memory, and writes instead permanently to the healthy hardware.

Comments: It will be several weeks before it is known if this works and solves the memory loss problem.
