Nasa’s Curiosity Mars rover has been put into “safe mode” after a computer glitch caused by corrupted files.
The robot, which is analysing rock samples on the red planet, is now running from a back-up computer.
Nasa scientists are looking into possible causes for the files on the robot’s flash memory being damaged.
The fault means the rover’s work has been put on temporary hold while the back-up computer is reconfigured so it can take full control.
