This image, taken by NASA's Phoenix Mars Lander's Surface Stereo Imager on Sol 50, or the 50th day of the mission, July 15, 2008, shows two holes at the top created by the lander's Robotic Arm's motorized rasp tool. The holes are about 1 centimeter (0.4 inch) apart.
The Phoenix Mission is led by the University of Arizona, Tucson, on behalf of NASA. Project management of the mission is led 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.
