Gilbert

         This mosaic was acquired by the Mars Exploration Rover Opportunity on Sol 1392 (December 24, 2007).   The dust on Pancam's sapphire window is evident in this mosaic. The rover was sitting inside Victoria Crater, at the Lyell stratigraphic layer (named for Charles Lyell, a Scottish geologist), and imaging Gilbert (named for Grove K. Gilbert, an American geologist), another potential target for instruments on the robotic arm. Pancam's 753nm, 535nm, and 432nm filters were used in making this mosaic.  Two versions are provided at full resolution: an approximate true color rendering, and a false color rendering which enhances the subtle color differences in the scene.
