Apollo 15 lunar surface exploration, August 1971. Close-up view of impact debris from an impact crater, with the blocks mostly being regolith breccia formed from soil compressed during the impact event. This view looks southeast, and was taken during the Apollo 15 third lunar surface extravehicular activity (EVA-3), at Station 9 near Scarp Crater. The Apennine Front is in the background, with Hadley Delta Mountain at right. Apollo 15 was the fourth manned mission to land on the Moon. The lunar lander 'Falcon' touched down in the Hadley region of the Moon on 30 July 1971. Astronauts David Scott and James Irwin spent a total of 18.5 hours outside their spacecraft, carrying out three exploration trips (EVAs) with the Lunar Roving Vehicle (used for the first time on this mission). Photographed by Scott on 2 August 1971.
