This view from the Surface Stereo Imager on NASA's Phoenix Mars Lander
shows a portion of the trench informally named "Snow White," with two
holes near the top of the image that were produced by the first test use
of Phoenix's rasp to collect a sample of icy soil.
The test was conducted on July 15, 2008, during the 50th Martian day, or
sol, since Phoenix landed, and the image was taken later the same day. The
two holes are about one centimeter (0.4 inch) apart. The image appears
three-dimensional when viewed through blue-red glasses.
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.
