Curiosity Performs Warm Reset

Mars Science Laboratory Mission Status Report

NASA's Mars rover Curiosity experienced an unexpected software reboot
(also known as a warm reset) yesterday (11/7/13) during a communications
pass as it was sending engineering and science data to the Mars Reconnaissance
Orbiter, for later downlinking to Earth. This computer reset occurred
about four-and-half hours after new flight software had been temporarily
loaded into the rover's memory. At the time the event occurred, Curiosity
was in the middle of a scheduled, week-long flight software update and
checkout activity.

"Telemetry later downlinked from the rover indicates the warm reset was
performed as would be expected in response to an unanticipated event,"
said Jim Erickson, project manager for the Mars Science Laboratory mission
at NASA's Jet Propulsion Laboratory, Pasadena, Calif.

A warm reset is executed by flight software when it identifies a problem
with one of its operations. The reset restarts the flight software into
its initial state. Since the reset, the rover has been performing operations
and communications as expected. The team is currently working toward understanding
the cause of the reset and returning the rover to normal operations. This
is the first time that Curiosity has executed a fault-related warm reset
during its 16-plus months of Mars surface operations.

NASA's Mars Science Laboratory Project is using Curiosity to assess whether
areas inside Gale Crater ever offered a habitable environment for microbes.
JPL, a division of the California Institute of Technology in Pasadena,
manages the project for NASA's Science Mission Directorate in Washington.
