THEMIS Image of the Day, March 28, 2019. This false-color VIS image is located in Arabia Terra. The image cuts across an ancient, almost obliterated impact crater, whose rim can be seen at the top and bottom of the image. In between lies a mostly flat 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.
