This image of Martian soil was taken by the Phoenix Lander's atomic force
microscope on Sol 74 of the mission, which began on May 25, 2008. This
image of a flat, smooth-surfaced particle is consistent with the
appearance of soil from Earth containing the mineral phyllosilicate.
The Phoenix Mission is led by the University of Arizona, Tucson, on behalf
of NASA. Project management of the mission is by JPL, Pasadena, Calif.
Spacecraft development was by Lockheed Martin Space Systems, Denver.
