During analysis of four safe-mode events this year, engineers for NASA's Mars Reconnaissance Orbiter project have identified a vulnerability to the effects of subsequent events. They are currently developing added protection to eliminate this vulnerability while they continue analysis of the string of incidents this year in which the spacecraft has spontaneously rebooted its computer or switched to a backup computer.
