This image captured by the Robotic Arm Camera aboard NASA's Phoenix Mars Lander on Sol 6, the sixth Martian day of the mission, (May 31, 2008) shows a close-up of the "Snow Queen" feature under the lander.

Swept clear of surface dust by the thruster rockets as Phoenix landed, the area has a smooth surface with layers visible and several smooth rounded cavities.

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.

Photojournal Note: As planned, the Phoenix lander, which landed May 25, 2008 23:53 UTC, ended communications in November 2008, about six months after landing, when its solar panels ceased operating in the dark Martian winter.
