THEMIS Image of the Day, September 14, 2018. Today’s VIS image shows part of northern Terra Sabaea, where hills are common. The blue tones are usually locations of basaltic sand.
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.
