AS15-97-13168 (31 July-2 Aug. 1971) --- A view of the flow structure on the rim and edge of the crater Tsiolkovsky in the highlands of the lunar farside, as photographed from lunar orbit by astronaut Alfred M. Worden in the Apollo 15 Command and Service Module (CSM). Note the scarp at the edge of the flow and elongated grooves on the flow surface. While astronauts David R. Scott and James B. Irwin descended in the Lunar Module (LM) "Falcon" to explore the moon's Hadley-Apennine landing site, Worden remained with the CSM in lunar orbit.
