Nasa’s Mars exploration rover Opportunity is set for a flash memory reformatting after experiencing an increasing number of computer resets.
The US space agency is preparing to download all useful data remaining in Opportunity’s flash memory to earth and switch the rover to an operating mode that does not use flash memory.
Flash memory retains data even when power is off.
Individual cells within a flash memory can wear out from repeated use.
Reformatting clears the memory while identifying bad cells and flagging them to be avoided, media reports said.
Opportunity has been active for more than a decade and is currently about 200 million km from earth.
