This NAC image shows Eastman, a crater newly named for Sioux author Charles A. (Ohiyesa) Eastman (1858-1939) and first seen by spacecraft by MESSENGER during the mission's first Mercury flyby. Eastman exhibits some features characteristic of a fresh, relatively young crater. The walls of Eastman have clearly visible terraces, and the central peak structure is well preserved. Eastman is located near Xiao Zhao , a crater previously named in April 2008.
