This mosaic was acquired by the Mars Exploration Rover Opportunity on Sol 4972 (January 18, 2018). This mosaic showcases the majority of a rock outcrop in front of the rover named Robledo. A bit to the left of the outcrop shown here is a another part of Robledo also imaged on Sol 4972. The rainbow shadows of Pancam and the rover's solar panels at the bottom of the right frames 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 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.
