The THEMIS VIS 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. Today's false color image shows a small section of Nili Fossae. The linear depression at the top of the image is one of the Nili Fossae graben. Dark blue in this filter combination indicates basaltic sand.
