Kovalevskaya (crater)
Kovalevskaya is a prominent lunar impact crater that is located on the far side of the Moon. It lies to the southwest of the larger walled plain Landau. To the south of Kovalevskaya are the craters Poynting and Fersman. This crater overlies nearly half of the large Kovalevskaya Q along the southwest rim. The outer rim of Kovalevskaya is generally well-formed and not significantly eroded. The inner walls have formed terraces and slumped shelves in places. At the midpoint of the interior floor is a pair of central peaks that are split down the middle by a valley running north–south. Some hills run to the east of these peaks, and there are some low hills near the northwest inner wall. The remainder of the floor is relatively level and free from significant impacts. This feature was named after the Russian mathematician Sofia Kovalevskaya Sofya Vasilyevna Kovalevskaya (; born Korvin-Krukovskaya; – 10 February 1891) was a Russian mathematician who made noteworthy contributi ...

Lunar Orbiter 5
Lunar Orbiter 5, the last of the "Lunar Orbiter series", was designed to take additional Project Apollo, Apollo and Surveyor program, Surveyor landing site photography and to take broad survey images of unphotographed parts of the Moon's far side. It was also equipped to collect selenodetic, radiation intensity, and micrometeoroid impact data and was used to evaluate the Manned Space Flight Network tracking stations and Apollo Orbit Determination Program. Mission summary The spacecraft was placed in a cislunar trajectory and on August 5, 1967 was injected into an elliptical near polar lunar orbit with an inclination of 85 degrees and a period of 8 hours 30 minutes. On August 7 the perilune was lowered to , and on August 9 the orbit was lowered to a , 3 hour 11 minute period. The spacecraft acquired photographic data from August 6 to 18, 1967, and readout occurred until August 27, 1967.

Kilometre
