NASA's Phoenix Mars Lander. The image was taken by the lander's Surface
Stereo Imager on the 131st Martian day, or sol, of the mission (Oct. 7,

winter approach Mars' northern plains.
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
