Memory Problems On Mars

NASA's Spirit rover continues to have computer problems. The latest glitches were three failures to store data in flash memory. Using flash memory ensures the data will be saved even if the rover is temporarily turned off.

Engineers aren't sure what's causing the recent odd behavior. NASA is calling it a kind of "amnesia." That might be taking things a bit far, but Spirit was supposed to last 90 days on Mars; so far, it has lasted roughly twenty times that long. If Spirit gets contrary now, nobody can reasonably complain.
