Approaching Gilbert

         This mosaic was acquired by the Mars Exploration Rover Opportunity on Sol 1441 (February 12, 2008).  The rover tested the sandy terrain with a wheel scuff while approaching this target of interest called Gilbert, named for geologist G. K. Gilbert. Subsequently, an in situ study of the left portion of this bedrock was conducted on this lowest stratigraphic layer approached to date in Victoria Crater. 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.
