Curiosity Rover Enters Precautionary Safe Mode

Mars Science Laboratory Mission Status Report

The team operating NASA's Curiosity Mars rover is taking steps to return
the rover to full activity following a precautionary stand-down over the
Fourth of July weekend.

Curiosity is now communicating with ground controllers and is stable.
The rover put itself into safe mode on July 2, ceasing most activities
other than keeping itself healthy and following a prescribed sequence
for resuming communications.

Engineers are working to determine the cause of safe-mode entry. Preliminary
information indicates an unexpected mismatch between camera software and
data-processing software in the main computer. The near-term steps toward
resuming full activities begin with requesting more diagnostic information
from Curiosity.

Curiosity has entered safe mode three times previously, all during 2013.

The rover landed in Mars' Gale Crater in August 2012. During its first
year on Mars, the mission achieved its goal by determining that, more
than 3 billion years ago, the region offered fresh-water lakes and rivers
with environmental conditions well-suited to supporting microbial life,
if life has ever existed on Mars. In continuing investigations, the mission
is learning more about the ancient wet environments and how and when they
evolved to drier and less habitable conditions.

NASA last week approved an additional two-year extension, beginning Oct.
1, 2016, for the Mars Science Laboratory Project, which developed and
operates Curiosity.

NASA's Jet Propulsion Laboratory, Pasadena, California, manages the project
for NASA's Science Mission Directorate, Washington. JPL is a division
of Caltech in Pasadena. For more information about Curiosity, visit:
