More Robledo

        This mosaic was acquired by the Mars Exploration Rover Opportunity from Sols 4976 (January 22, 2018) - 4988 (February 3, 2018). About 77 degrees across at the widest point, this mosaic showcases a rocky outcropping named Robledo in front of the rover. The set of rocks above the Pancam's shadow in the right portion of this view were also imaged in a previous mosaic of Robledo on Sol 4972. The rainbow shadows of Pancam and other parts of the rover in the bottom frames of this mosaic reminds us of the complicated process Opportunity uses to obtain color images. Each frame is made in color by stacking three separate images of red, green, and blue filtered light. Because of the time delay between each frame and each filter, the neat rainbow artifact of the shadows is created from the sun progressing across the sky changing the length of shadows. Pancam's 753 nm, 535 nm, and 432 nm filters were used in 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.
