This image covers a region of Mars near Nili Fossae that contains some of the best exposures of ancient bedrock on Mars.

The enhanced-color subimage shows part of the ejecta from an impact crater. The impact broke up already diverse rocks types and mixed them together to create this wild jumble of colors, each representing a different type of rock.
