THEMIS Image of the Day, March 26, 2019. Today’s false-color VIS image is located in Elysium Planitia. The linear depressions at the top of the image are created by tectonic faults, where the center block of material has dropped downward between two parallel faults. Blue tones, like those at the bottom of the image, are indicative of basaltic sands.
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.
