THEMIS Image of the Day, October 21, 2016. Today’s false color image shows part of the interior deposit of Firsoff Crater. (This image lies just west of the one from October 13 and partly overlaps it.) The dark blue material is most likely basaltic sand. 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.
