This image shows four of the eight cells in the Thermal and Evolved-Gas
Analyzer, or TEGA, on NASA's Phoenix Mars Lander. TEGA's ovens, located
underneath the cells, heat soil samples so the released gases can be
analyzed.
Left to right, the cells are numbered 7, 6, 5 and 4. Phoenix's Robotic Arm
delivered soil most recently to cell 6 on the 137th Martian day, or sol,
of the mission (Oct. 13, 2008).
Phoenix's Robotic Arm Camera took this image at 3:03 p.m. local solar time
on Sol 138 (Oct. 14, 2008).
Phoenix landed on Mars' northern plains on May 25, 2008.
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.
