THEMIS Image of the Day, August 30, 2018. Today’s false-color image shows the floor of Proctor Crater, including the large dune field. Basaltic sands are typically blue in false-color images. Proctor Crater is located 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.
