Several of the trenches dug by NASA's Phoenix Mars Lander are displayed in
this approximately true color mosaic of images from the lander's Surface
Stereo Imager camera.
The component images were taken on various dates during the five months
that Phoenix studied its surroundings after landing on a Martian arctic
plain on May 25, 2008.
The Phoenix Mission was led by the University of Arizona, Tucson, on
behalf of NASA. Project management of the mission was by NASA's Jet
Propulsion Laboratory, Pasadena, Calif. Spacecraft development was by
Lockheed Martin Space Systems, Denver.
