Interesting news. Could this have anything to do with the passing of ISON a while back. Is it really a powerglitch or are they hiding something?
Mars Rover Suffers Glitch, Operations On Hold(from the article) The issue with roving on another planet is that should something go wrong, there’s no mechanic for millions of miles and any fix to an electrical problem needs to be found remotely. On Sunday, NASA’s Mars rover Curiosity has experienced such a glitch, ceasing all roving and science operations.
On Nov. 17, Curiosity’s 456th day (or sol) on Mars, mission managers were alerted to a “voltage change” between the rover’s chassis and 32-volt power bus that distributes electricity to systems throughout the rover, a JPL news release reports. Although the problem is significant enough to warrant close inspection by engineers, this isn’t the first time the rover has suffered a glitch of this nature and it did
not trigger an automatic “safe-mode.” Also, there is “no indication” to suggest that this event has any connection to Curiosity’s safe-mode that was triggered by a computer re-boot earlier this month.
