NASA's Mars Odyssey orbiter experienced about 21 hours in a reduced-activity precautionary status ending at about 10 a.m. PDT (1 p.m. EDT) on Thursday, July 12.

The orbiter put itself in the precautionary, Earth-pointed status called safe mode, at about 1 p.m. PDT (4 p.m. EDT) on July 11, as it finished a maneuver adjusting, or trimming, its orbit. Odyssey's computer did not reboot, so diagnostic information was subsequently available from the spacecraft's onboard memory. Based on analysis of that information, the mission's controllers sent commands yesterday morning taking Odyssey out of safe mode and reorienting it to point downward at Mars.

"We are on a cautious path to resume Odyssey's science and relay operations soon," said Gaylon McSmith, Odyssey project manager at NASA's Jet Propulsion Laboratory, Pasadena, Calif. "We will also be assessing whether another orbit trim maneuver is warranted."

The thruster burn for Wednesday's orbit-trim maneuver lasted 1.5 seconds, as planned, which was shorter than any previous orbit-trim maneuver of the mission's decade at Mars. The spacecraft's onboard capability for maintaining orientation during the burn put unexpectedly high demand on a reaction wheel in the attitude control system, which prompted the change to safe mode.

NASA launched the Mars Odyssey spacecraft on April 7, 2001, and it arrived at Mars Oct. 24, 2001. It has worked at Mars longer than any other Mars mission in history. Besides conducting its own scientific observations, it serves as a communication relay for robots on the Martian surface. NASA plans to use Odyssey and the newer Mars Reconnaissance Orbiter as communication relays for the Mars Science Laboratory mission during the landing and Mars-surface operations of its Curiosity rover.

Odyssey is managed by JPL for NASA's Science Mission Directorate in Washington. Lockheed Martin Space Systems in Denver built the spacecraft. JPL and Lockheed Martin collaborate on operating the spacecraft. For more about the Mars Odyssey mission, visit: http://mars.jpl.nasa.gov/odyssey .
