Arabia Terra Crater - False Color

This false color image shows most of the floor of an unnamed crater in southern Arabia Terra. The wide variety of colors indicates a complex geologic history. Dark blue in this false color combination is typically basaltic sand. It appears that in addition to small sand dunes a scattering of sand also covers part of the crater floor.

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.
