Kosmos 434 ( ‹See Tfd› Russian : Космос 434; meaning Cosmos 434), also known as T2K No.3, was the final uncrewed test flight of the Soviet LK Lander. It performed the longest burn of the four uncrewed LK Lander tests, validating the backup rocket engine of the LK's Blok E propulsion system. It finished in a 186 km by 11,804 km orbit. This test qualified the lander as flightworthy.
The LK was the only element of the Soviet human lunar programs that reached this status. In 1980-81 there were fears that it might carry nuclear fuel. When it reentered over Australia on August 22, 1981 the Soviet Foreign Ministry in Australia admitted that Kosmos 434 was an "experiment unit of a lunar cabin," or lunar lander.
The TKS spacecraft was a Soviet spacecraft conceived in the late 1960s for resupply flights to the military Almaz space station.
Kosmos 133, Soyuz 7K-OK No.2, was the first uncrewed test flight of the Soyuz spacecraft, and first mission of the Soyuz programme, as part of the Soviet space programme.
Kosmos 213 was one of a series of Soviet Soyuz programme test spacecraft whose purpose was to further test and develop the passenger version. Scientific data and measurements were relayed to earth by multichannel telemetry systems equipped with space-borne memory units. Kosmos 212 and Kosmos 213 automatically docked in orbit on April 15, 1968. Both spacecraft landed on Soviet territory.
Kosmos 379, also known as T2K No.1, was an uncrewed test of the LK in Earth orbit.
Kosmos 573 was an unmanned test of the Soyuz without solar arrays in 1973. It did not dock with a space station.
Kosmos 613 was a long-duration orbital storage test of the Soyuz Ferry in preparation for long stays attached to a space station.
The LK was a lunar module developed in the 1960s as a part of several Soviet crewed lunar programs. Its role was analogous to the American Apollo Lunar Module (LM). Three LK modules, of the T2K variant, were flown without crew in Earth orbit, but no LK ever reached the Moon. The development of the N1 launch vehicle required for the lunar flight suffered setbacks, and the first Moon landings were achieved by US astronauts on Apollo 11. As a result, having lost the Space Race, both the N1 and the LK programs were cancelled without any further development.
Kosmos 398, also known as T2K No.2, was the second uncrewed test flight of the Soviet LK lander, using the T2K version. It followed the same program as Kosmos 379, launching on February 26, 1971 into a 276 km by 196 km orbit. It main objective was to validate contingency abort-to-lunar orbit manoeuvres.
Soyuz 7K-OK was the first generation of Soyuz spacecraft and was flown between 1967 and 1971. The 7K-OK was used for the first ferry flights to the Salyut space station program, beginning a long history of space station service that continues with the International Space Station (ISS).
Kosmos 116, also known as DS-P1-Yu No.6 was a Soviet satellite which was used as a radar calibration target for tests of anti-ballistic missiles. It was built by the Yuzhnoye Design Bureau, and launched in 1966 as part of the Dnepropetrovsk Sputnik programme.
Kosmos 123, also known as DS-P1-Yu No.5 was a Soviet satellite which was used as a radar calibration target for tests of anti-ballistic missiles. It was built by the Yuzhnoye Design Bureau, and launched in 1966 as part of the Dnepropetrovsk Sputnik programme.
Kosmos 152, also known as DS-P1-Yu No.7 was a Soviet satellite which was used as a radar calibration target for tests of anti-ballistic missiles. It was built by the Yuzhnoye Design Bureau, and launched in 1967 as part of the Dnepropetrovsk Sputnik programme, and had a mass of 325 kilograms (717 lb).
Kosmos 165, also known as DS-P1-Yu No.11 was a radar calibration target satellite which was used by the Soviet Union for tests of anti-ballistic missiles. It was a 400 kilograms (880 lb) spacecraft, which was built by the Yuzhnoye Design Office, and launched in 1967 as part of the Dnepropetrovsk Sputnik programme.
Kosmos 173, also known as DS-P1-Yu No.8 was a Soviet satellite which was used as a radar calibration target for tests of anti-ballistic missiles. It was a 325 kilograms (717 lb) spacecraft, was built by the Yuzhnoye, and launched in 1967 as part of the Dnepropetrovsk Sputnik programme.
Kosmos 145, also known as DS-U2-M No.2, was a Soviet satellite which was launched in 1967 as part of the Dnepropetrovsk Sputnik programme. It was a 250 kilograms (550 lb) spacecraft, which was built by the Yuzhnoye Design Bureau, and was used to conduct tests involving atomic clocks.
Kosmos 14, also known as Omega No.1, was a satellite which was launched by the Soviet Union in 1963. It was an Omega satellite, derived from the Dnepropetrovsk Sputnik series.
Kosmos 47 is the designation of an uncrewed test flight of a prototype Soviet Voskhod spacecraft, the first multiple-occupant spacecraft. Launched on 6 October 1964, the successful flight paved the way for the first crewed mission, Voskhod 1, which occurred just 6 days later on 12 October 1964.
Kosmos 15 or Zenit-2 No.9 was a Soviet optical film-return reconnaissance satellite which was launched in 1963. A Zenit-2 spacecraft, Kosmos 15 was the ninth of eighty-one such satellites to be launched.
Kosmos 20 or Zenit-2 No.13 was a Soviet optical film-return reconnaissance satellite which was launched in 1963. A Zenit-2 satellite, Kosmos 20 was the thirteenth of eighty-one such spacecraft to be launched.
Soyuz 7K-L1E was a Soviet uncrewed modified Soyuz 7K-L1 spacecraft. Also called a dummy Soyuz 7K-LOK. Two were built, one Soyuz 7K-L1E was successfully launched into Low Earth Orbit on Proton rocket and is known as Kosmos 382. The other Soyuz 7K-L1E was placed on a N1 rocket, which failed at launch. The Soyuz spacecraft was first used in 1967 as the main crewed spacecraft and is still in use. Many Soyuz variations have been built and the Soyuz 7K-L1E was an uncrewed variation.
