Marathon Valley Floor

        This mosaic was acquired by the Mars Exploration Rover Opportunity on Sol 4138 (September 14, 2015). While exploring Marathon Valley, Opportunity took this small mosaic of the valley floor that is approximately 30 degrees wide. Pancam's 753nm, 535nm, and 432nm filters were used in this mosaic.  Three versions are provided at full resolution: an approximate true color rendering, a false color rendering which enhances the subtle color differences in the scene, and a stereo anaglyph for 3D viewing through red-blue glasses.
