This anaglyph was taken by NASA's Phoenix Mars Lander's Surface Stereo Imager Oct. 7, 2008. The anaglyph highlights the depth of the trench, informally named 'La Mancha,' and reveals the ice layer beneath the soil surface. 3-D glasses are necessary.

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.
