The 6-year-old rover’s latest memory lapse occurred Oct. 24 and came more than six months after a series of four other amnesia events earlier this year. During the events, the plucky rover failed to record science observations in the part of its flash computer memory that stores information overnight when other systems are powered down.
“We still don’t have information about what causes these amnesia events,” said rover project manager John Callas at NASA’s Jet Propulsion Laboratory, Pasadena, Calif., in an update.
In the latest event, Spirit did not use its flash memory between Oct. 24 and Oct. 27. The rover does have an alternate memory system in which to store data, but must beam that information home to Earth before entering an overnight sleep period, mission managers said.
Callas said engineers are weighing Spirit’s amnesia problem to determine how it may affect day-to-day operations for the long term. Aside from the memory glitch, the rover is in good health and communicating with Earth. …
Aliens? No… I don’t remember any aliens.
