Tsiolkovskiy (crater)
Tsiolkovskiy is one of the largest craters of Upper (Late) Imbrian age.
Characteristics
Tsiolkovskiy is one of the most prominent features on the far side of the Moon. It possesses high, terraced inner walls and a well-formed central peak, which rises over 3200 m above the floor of the crater. The floor is unusual for a crater on the far side, as it is covered by the dark-hued mare that is characteristic of the maria found on the near side. The distribution of the mare material is not symmetrical across the floor, but is instead more heavily concentrated to the east and south. There is also a protruding bay of darker material that reaches the wall to the west-northwest. The remainder of the floor has the same albedo as the terrain surrounding the crater.
A row of small craters in Mendeleev crater far to the northeast are called Catena Mendeleev, and the row points directly at Tsiolkovsky. For this reason the craters are believed to be secondaries from the Tsiolkovsky impact.
This feature was discovered on photographs sent back by the Russian spacecraft Luna 3, and was subsequently imaged by several of the American Lunar Orbiters and then by Apollo astronauts.
Apollo 17 Astronaut Harrison "Jack" Schmitt and other scientists (Schmitt was the only trained scientist, a geologist, to walk on the Moon) strongly advocated Tsiolkovskiy as the landing site of Apollo 17, using small communications satellites deployed from the Command/Service Module for communication from the far side of the Moon. NASA vetoed the idea as too risky, and Apollo 17 instead landed in the Taurus–Littrow valley on December 11, 1972.

Satellite craters
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Tsiolkovskiy.
