Tsiolkovsky Crater
This overhead photograph shows details of the interior of the Tsiolkovsky Crater. Unlike many large craters, the floor of Tsiolkovsky is covered with mare material and is quite smooth.
The crater itself is fairly circular, but the mare-covered region is distinctly noncircular. This is a rare example of mare material on the Moon's farside. The complex terracing and slump blocks on the interior side of the crater rim are typical of many large impact craters. The prominent central peak is also typical of large craters.
This image was taken by the crew of Apollo 15 in July 1971.
