Mars Exploration Rover Spirit is acting a little strange. Over the Easter weekend, it would appear that the tenacious little Mars explorer rebooted its computer not once, but at least two times. Mission scientists were alerted to the problem as some of the communication sessions from Spirit-to-Earth were irregular, prompting mission control to investigate the [...]

Mars Rover Inexplicably Reboots Computer

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. (More...

Spirit Healthy but Computer Reboots Raise Concerns

The team operating NASA's Mars Exploration Rover Spirit is examining data received from Spirit in recent days to diagnose why the rover apparently rebooted its computer at least twice over the April 11-12 weekend.


"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 John Callas of NASA's Jet Propulsion Laboratory, Pasadena, Calif., project manager for Spirit and twin-rover Opportunity. "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." (More...

At the risk of digression...
Perhaps it's something to do with Easter Spirit! :)

I hope, at the end of the day, she is alright. Spirit and Opportunity have been absolutely amazing, these past years.

Long may they continue to be Earth's Roving Ambassadors!
