One of the Mars rovers is having a bit of a problem. Maybe.
NASA's Mars Exploration Rover Spirit mysteriously rebooted its computer twice over the weekend; mission controllers are examining data sent back by Spirit to see if they can diagnose the problem behind the glitch.
"While we don't have an explanation yet, we do know that Spirit's batteries are charged, the solar arrays are producing energy and temperatures are well within allowable ranges. We have time to respond carefully and investigate this thoroughly," said Spirit project manager John Callas of NASA's Jet Propulsion Laboratory, Pasadena, Calif. "The rover is in a stable operations state called automode and taking care of itself. It could stay in this stable mode for some time if necessary while we diagnose the problem."
Well, I guess you could expect a few glitches from a system that's been operating five years longer that was expected.
