|NASA's Phoenix Mars Lander's Surface Stereo Imager took this image on Sol 14 (June 8, 2008), the 14th Martian day after landing. Soil from the right trench, informally called "Baby Bear," was delivered to Phoenix's Thermal and Evolved-Gas Analyzer, or TEGA, on Sol 12 (June 6). The trench on the left is informally called "Dodo" and was dug as a test. Each of the trenches is about 9 centimeters (3 inches) wide.
