This image shows soil on the doors of the Thermal and Evolved Gas Analyzer (TEGA) onboard NASA's Phoenix Mars Lander. The image was taken by the lander's Robotic Arm Camera on the 131st Martian day, or sol, of the mission (Oct. 7, 2008). This sample delivered to TEGA was named "Rosy Red."
The Phoenix Mission is led by the University of Arizona, Tucson, on behalf of NASA. Project management of the mission is by NASA's Jet Propulsion Laboratory, Pasadena, Calif. Spacecraft development is by Lockheed Martin Space Systems, Denver.
Photojournal Note: As planned, the Phoenix lander, which landed May 25, 2008 23:53 UTC, ended communications in November 2008, about six months after landing, when its solar panels ceased operating in the dark Martian winter.
