This observation gives us a nice view of dunes on the floor of Capen Crater, located in Terra Sabea.
However, our primary interest is with the dark-toned layered material the dunes are mostly covering up. Capen is a 70-kilometer impact crater named for astronomer Charles Capen, an apprentice to Clyde Tombaugh, the discoverer of Pluto.
