NASA successfully reboots Mars orbiter’s computer
March 11, 2009
PASADENA, Calif. ” NASA has successfully commanded an orbiting Mars spacecraft to reboot its onboard computer.
Scientists had been worried that the Mars Odyssey’s memory may have been corrupted from exposure to space radiation.
Mission manager Gaylon McSmith of NASA’s Jet Propulsion Laboratory said Wednesday’s restart went without a hitch.
McSmith said an added benefit was that the procedure also restored the spacecraft’s backup systems. Engineers hadn’t been sure those systems would work if needed because a power management component had become inoperable.
The risky reboot was delayed a day after engineers noticed a temperature spike on a navigation camera. An investigation revealed a heater circuit was left on.
It will take several days for Odyssey to resume science operations. The spacecraft has been orbiting Mars since 2001.
