This anaglyph, taken by NASA's Phoenix Mars Lander's Surface Stereo
Imager, was taken on the 131st Martian day, or sol, of the mission (Oct.
7, 2008). The anaglyph highlights the depth of the trench, informally
named "La Mancha," and reveals the ice layer beneath the soil surface. The
trench's depth is about 5 centimeters deep.
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.
