NASA's Phoenix Mars Lander's Surface Stereo Imager took this image on Sol
11 (June 5, 2008), the eleventh day after landing. It shows the trenches
dug by Phoenix's Robotic Arm. The trench on the left is informally called
"Dodo" and was dug as a test. The trench on the right is informally called
"Baby Bear." The sample dug from Baby Bear will be delivered to the
Phoenix's Thermal and Evolved-Gas Analyzer, or TEGA. The Baby Bear trench
is 9 centimeters (3.1 inches) wide and 4 centimeters (1.6 inches) deep.
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.
