A pan and zoom animation of the informally named Dodo (on left) and Goldilocks (on right) trenches as seen by the Surface Stereo Imager (SSI) aboard NASA's Phoenix Mars Lander. This animation was based on conditions on the Martian surface on Sol 17 (June 11, 2008), the 17th Martian day of the mission. Baby Bear is the name of the sample taken from Goldilocks and delivered to the Thermal and Evolved-Gas Analyzer (TEGA) instrument.
