If you think fixing computer problems on your PC is a pain, trying fixing them from 125 million miles away. That's exactly what NASA's JPL Mars Exploration Rover (MER)
team will be doing soon.
The Opportunity rover, which has been exploring Mars for ten years now, has been randomly rebooting for several months. Because the rover always came back, the team tried ignoring the problem, but just like you with a misbehaving computer, the day finally came when they couldn't put up up with it anymore.
