The various named features present in this color image, Qi Baishi, Hovnatanian, Kalidasa, and Tolstoj, create a stunning depiction of Mercury's scarred and variable surface. Tolstoj, the large basin in the bottom right of the image, represents the war and peace of its namesake's famous novel through its smooth, light-colored center and rough, dark blue exterior.

This image was acquired as part of MDIS's color base map. The color base map is composed of WAC images taken through eight different narrow-band color filters and will cover more than 90% of Mercury's surface with an average resolution of 1 kilometer/pixel (0.6 miles/pixel). The highest-quality color images are obtained for Mercury's surface when both the spacecraft and the Sun are overhead, so these images typically are taken with viewing conditions of low incidence and emission angles.
