This contrast-enhanced image was acquired at the Phoenix landing site on
Sol 4 by Phoenix's Robotic Arm Camera (RAC). As seen in the top center,
the exhaust from the descent engine has blown soil off to reveal either
rock or ice, which has not yet been determined.
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
