Rhysling (crater)
Rhysling is a feature on Earth's Moon, a crater in the Hadley–Apennine region. Astronauts David Scott and James Irwin stopped near the west rim of it in 1971, on the Apollo 15 mission, during EVA 1. Geology Station 3 was about 125 meters west of Rhysling, and a single piece of vesicular basalt was collected there (sample 15016). The rock is sometimes called the seatbelt basalt.
Rhysling is located less than 1 km east of Hadley Rille, less than 1 km northwest of Earthlight crater, and about 2 km south of the Apollo 15 landing site itself, at Last crater.
The crater was named by the astronauts, and the name was formally adopted by the IAU in 1973.
