THEMIS Image of the Day, February 20, 2019. Today’s image shows part of the floor of Pasteur Crater. The deposit in the southwest part of the floor is a fill deposit that is undergoing erosion. Small sand dunes are found within the eroding material. Pasteur Crater is located between Arabia Terra and Terra Sabaea.
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.
