Mars Rover Losing Its Memory

The Mars Exploration Rover known as Spirit has been experiencing some memory problems since October 24. Spirit usually records its day's activities onto flash memory and then takes a break. This break is similar to sleep and the robot can usually retain its flash memory when it wakes up. However, it has been losing this memory recently. Surprisingly, Spirit is in pretty good health otherwise. The Rover has been stuck in a patch of soft, Martian soil since April but has still collected data for NASA.

What do you think will happen to Spirit?
