Mars Reconnaissance Orbiter In Safe Mode After Reboot
Pasadena CA (SPX) Jun 08, 2009 NASA's Mars Reconnaissance Orbiter is in safe mode and in communications with Earth after an unexpected rebooting of its computer Wednesday evening, June 3. The spontaneous reboot resembles a Feb. 23 event on the spacecraft. Engineers concluded the most likely cause for that event was a cosmic ray or solar particle hitting electronics and causing an erroneous voltage reading. Jim Erickson, Mars Reconnaissance Orbiter project manager at NASA's Jet Propulsion Laboratory, Pasadena, Calif., said, "The spacecraft is sending down high-rate engineering data, power positive, batteries fully charged, Sun pointed and thermally safe. The flight team is cautiously bringing the orbiter back to normal operations. We should be resuming our exploration of Mars by next week." The reboot occurred at approximately 6:10 p.m. PDT (9:10 p.m. EDT) on June 3. This is the sixth time since the spacecraft's August 2005 launch that it has entered safe mode, which is its programmed precaution when it senses a condition for which it does not know a more specific response.
