THEMIS Image of the Day, April 21, 2017. Today’s false color image shows a portion of the large sand sheet with surface dune forms located on the floor of Proctor Crater in Noachis Terra.
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.
