THEMIS Image of the Day, July 29, 2016. Today’s false color image shows the northern tip of Baetis Mensa. In false color images dark blue is often basaltic sands. In this image it is possible to trace the sands from the erosion of Beatis Mensa moving down the canyon gullies to the floor of Ophir Chasma. The THEMIS camera contains 5 filters. The data from different filters can be combined in multiple ways to create a false color image. These false color images may reveal subtle variations of the surface not easily identified in a single band image.
