This image was acquired by NASA's Phoenix Mars Lander's Surface Stereo
Imager on Sol 43, the 43rd Martian day after landing (July 8, 2008). This
image shows the trench informally called "Snow White."
Two samples were delivered to the Wet Chemistry Laboratory, which is part
of Phoenix's Microscopy, Electrochemistry, and Conductivity Analyzer
(MECA). The first sample was taken from the surface area just left of the
trench and informally named "Rosy Red." It was delivered to the Wet
Chemistry Laboratory on Sol 30 (June 25, 2008). The second sample,
informally named "Sorceress," was taken from the center of the "Snow
White" trench and delivered to the Wet Chemistry Laboratory on Sol 41
(July 6, 2008).
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.
