Orbiter Recovering from Precautionary Pause in Activity

Mars Odyssey Mission Status Report

NASA's Mars Odyssey orbiter, which has been in service at Mars since October
2001, put itself into safe mode -- a protective standby status -- on Dec.
26, while remaining in communication with Earth.

The Odyssey project team has diagnosed the cause -- an uncertainty aboard
the spacecraft about its orientation with regard to Earth and the sun
-- and is restoring the orbiter to full operations. Odyssey's communication-relay
service for assisting Mars rover missions is expected to resume this week,
and Odyssey's own science investigations of the Red Planet are expected
to resume next week.

The orbiter's knowledge of its orientation was restored Dec. 26 by resetting
the inertial measurement unit and the circuit card that serves as interface
between that sensor, the flight software and the star tracker, for determining
spacecraft attitude. The mission last experienced a similar fault and
solution in December 2013.

Mars Odyssey left Earth on April 7, 2001, entered orbit around Mars on
Oct. 24, and began systematically examining Mars in February 2002. In
December 2010, it surpassed the previous record for longevity of a robotic
mission at Mars. The Mars Odyssey Project has been extending that record
daily for more than six years.

In addition to its direct contributions to planetary science, Odyssey
provides important support for other missions in NASA's Journey to Mars
through communication-relay service and observations of candidate landing
sites.

NASA's Jet Propulsion Laboratory, a division of Caltech in Pasadena, California,
manages the Mars Odyssey Project for NASA's Science Mission Directorate
in Washington. Lockheed Martin Space Systems, Denver, built the spacecraft
and collaborates with JPL in mission operations. For more information
