Ophir Chasma's history book (THEMIS_IOTD_20160203)
Today's false color image shows part of Ophir Chasma. The large brownish feature in the lower section of the image is part of the layered deposits on the floor of Ophir and other canyons that are similarly part of Valles Marineris. Scientists think these layers record the Martian past climate history, like pages in a history book. (The wavy edges of the image are a result of elevation variations and a unique period of spacecraft orientation.)
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.
The scene here spans 25 x 73 kilometers (16 x 45 miles). To see where on Mars this area lies, and to download high-resolution versions of the image, see: bit.ly/1TDxVuX
