Computers for rovers similar to those on many other spacecraft
In depth look at Mars rovers Spirit and other spacecraft computers. NASA engineers diagnose repeated reboots and irregularities while remote fixes are limited. The RAD6000 single board computer and Wind River Systems VxWorks OS provide space ready hardware and software. The article notes the conservative space community and reliance on proven systems like Pathfinder and Stardust.

Spirit rover in critical condition on Mars faces reboot crisis
NASA officials say the Spirit rover is in critical condition on Mars after days of gibberish data and repeated reboots. Engineers scramble to diagnose underlying hardware problems as Opportunity nears Mars for its own landing amid an $820 million double mission and a two-strong team effort.
