Hertzsprung Site
Date: 25 May 2010

This image shows fresh boulders on the inner ring of Hertzsprung basin, thought to be nearly pure anorthosite. LROC's narrow angle camera image focuses in on the Hertzsprung Constellation region of interest detailing a portion of the inner ring (270 km or 168 miles diameter) of Hertzsprung basin (570 km or 354 miles diameter) on the lunar far side. This basin is of Nectarian age (ancient) and is intermediate in size between two-ring basins (e.g., Schrodinger) and larger, multi-ring basins (e.g., Orientale). As such, it excavates material from an intermediate depth that helps us better understand the composition and structure of different zones of the lunar crust. LROC NAC image M112421089RE. Image is approximately 690 meters or 755 yards across and the Sun is from the right of the frame (east).
