Casper Crater

         This mosaic was acquired by the Mars Exploration Rover Opportunity on Sol 4717 and 4718 (May 1 and 2, 2017).  Casper Crater, imaged here in an approximately 30 degree wide mosaic, is a small crater about 30 meters (~100 feet) southeast of Orion Crater. The thought is that both Casper and Orion crater, as well as many other small craters in the area, were formed as secondary craters made from impact ejecta from a large, fresh crater to the west of Opportunity's drive path. The fresh crater is located roughly 330 meters to the west of Opportunity's location on Sol 4720 (the bottom left in the linked image). Pancam's 753 nm, 535 nm, and 432 nm filters were used in making 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.
