THEMIS Image of the Day, April 4, 2019. Oyama Crater dominates the top of this VIS image. Oyama Crater is located in Arabia Terra, just west of Mawrth Vallis. The two craters at the bottom of the image are unnamed.
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.
