Mars rover Opportunity, which has been exploring the Red Planet for more than 10 years, is suffering from memory problems, NASA has said.
The six-wheeled vehicle – not to be confused with Curiosity, which launched in 2011 – keeps resetting unexpectedly.
The Opportunity team thinks an age-related fault affecting the flash memory used by the robot is to blame.
It is hard enough to diagnose and fix computer problems when the machine is sitting on a desk just a few feet away. It’s quite another thing to do all that when the ‘computer’ is many millions of kilometres away. Impressive stuff.
