THEMIS Image of the Day, April 1, 2019. Today’s VIS image shows part of the floor of Rutherford Crater. Blue tones in false color images are indicative of basaltic sand. Rutherford Crater is approximately 107 km (66 miles) in diameter. This crater is located in Arabia Terra.
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.
