THEMIS Image of the Day, February 19, 2019. This VIS image shows part of the floor of Herschel Crater.
Sand dunes are visible at the bottom of the image. The dark blue in this false color image typically indicates basaltic sands. Early morning shadows can be seen to the left of the hills at the center of the image. Herschel Crater is located in Terra Cimmeria.
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.
