South Ray crater is a small crater in the Descartes Highlands of the Moon photographed from the lunar surface by the astronauts of Apollo 16.
The astronauts John Young and Charles Duke explored the area between the craters over the course of three EVAs using a Lunar Roving Vehicle, or rover.
Duke photographed South Ray from there with a 500-mm lens.
The astronauts observed that the ejecta of South Ray was very bouldery, and reported that it would have been difficult or impossible to drive there on their rover.
