AS15-85-11514 (31 July-2 Aug. 1971) --- Astronaut David R. Scott, commander, standing on the slope of Hadley Delta, uses a 70mm camera during Apollo 15 extravehicular activity (EVA) on the lunar surface. He is 10.5 miles (or 17.5 kilometers) from the base of the Apennine Mountains seen in the background. Scott carries tongs in his left hand. The Lunar Roving Vehicle (LRV) is in the background. This view is looking east. While astronauts Scott and James B. Irwin, lunar module pilot, descended in the Lunar Module (LM) "Falcon" to explore the moon, astronaut Alfred M. Worden, command module pilot, remained with the Command and Service Module (CSM) in lunar orbit.
