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 613 was a long-duration orbital storage test of the Soyuz Ferry in preparation for long stays attached to a space station.
Kosmos 2175 was a Russian Yantar-4K2 photo reconnaissance satellite. It was the first satellite to be launched by the Russian Federation, following the breakup of the Soviet Union. It was launched by a Soyuz-U carrier rocket, flying from the Plesetsk Cosmodrome, on 21 January 1992.
Yantar is a series of Russian reconnaissance satellites, which supplemented and eventually replaced the Zenit spacecraft. Kosmos 2175, a Yantar-4K2 or Kobalt spacecraft, was the first satellite to be launched by the Russian Federation following the dissolution of the Soviet Union. Yantar-Terilen was the first real-time digital system. Yantar satellites also formed the basis for the later Orlets, Resurs and Persona satellites. 179 have been launched, nine of which were lost in launch failures. All Yantar satellites were launched using the Soyuz-U carrier rocket until Kosmos 2480 in 2012 which was announced as the last launch of that rocket from Plesetsk. Subsequent launches used the modernized Soyuz-2.1a rocket. The last Yantar mission was Kosmos 2505, a Yantar-4K2M or Kobalt-M, launched on 5 June 2015. Reconnaissance missions have been taken over by the Persona class of satellites.
Kosmos 4, also known as Zenit-2 No.2 and occasionally in the West as Sputnik 14 was the first Soviet reconnaissance satellite to successfully reach orbit.
Kosmos 7, also known as Zenit-2 No.4 and occasionally in the West as Sputnik 17 was a Soviet reconnaissance satellite launched in 1962. It was the seventh satellite to be designated under the Kosmos system, and the second successful launch of a Soviet reconnaissance satellite.
Kosmos 10, also known as Zenit-2 No.5, was a Soviet reconnaissance satellite launched in 1962. It was the tenth satellite to be designated under the Kosmos system, and the fourth successful launch of a Soviet reconnaissance satellite, following Kosmos 4, Kosmos 7 and Kosmos 9.
Kosmos 97, also known as DS-U2-M No.1, was a Soviet satellite which was launched in 1965 as part of the Dnepropetrovsk Sputnik programme. It was a 267 kilograms (589 lb) spacecraft, which was built by the Yuzhnoye Design Bureau, and used to conduct tests involving atomic clocks.
Kosmos 261, also known as DS-U2-GK No.1, was a Soviet satellite which was launched in 1968 as part of the Dnepropetrovsk Sputnik programme. It was a 347-kilogram (765 lb) spacecraft, which was built by the Yuzhnoye Design Bureau, and was used to study the density of air in the upper atmosphere, and investigate aurorae. Kosmos 261 set the way for the Intercosmos Program. Hungary, Poland, Romania, Czechoslovakia, DDR and Bulgaria were the six Soviet Bloc countries that collaborated in the experiments on board the satellite.
Kosmos 262, also known as DS-U2-GF No.1, was a Soviet satellite which was launched in 1968 as part of the Dnepropetrovsk Sputnik programme. It was a 352-kilogram (776 lb) spacecraft, which was built by the Yuzhnoye Design Bureau, and was used to study the Sun.
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 23, also known as Omega No.2, was a satellite which was launched by the Soviet Union in 1963. It was an Omega satellite, derived from the Dnepropetrovsk Sputnik series. It was a 347 kilograms (765 lb) spacecraft, which was built by the Yuzhnoye Design Office, and was used to conduct experiments with the use of gyroscopes to control spacecraft, for VNIIEM.
Kosmos 2471, also known as Glonass-K1 No. 11L or Glonass-K No. 701, was a Russian navigation satellite which was launched in 2011. The first Glonass-K satellite to be launched, it was one of two Glonass-K1 spacecraft which served as prototypes for the operational Glonass-K2 spacecraft.
Kosmos 2480 is a Russian Kobalt-M reconnaissance satellite which was launched in 2012 by the Russian Aerospace Defence Forces. It was the last launch of a Soyuz-U rocket launched from Plesetsk Cosmodrome.
Kosmos 2472 was a Russian Kobalt-M reconnaissance satellite which was launched in 2011 by the Russian Aerospace Defence Forces. It was launched in June 2011 and remained in orbit until October 2011.
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.
Kosmos 46 or Zenit-2 No.23 was a Soviet, first generation, low resolution, optical film-return reconnaissance satellite launched in 1964. A Zenit-2 spacecraft, Kosmos 46 was the twenty-second of eighty one such satellites to be launched and had a mass of 4,730 kilograms (10,430 lb).
Kosmos 2501, also known as Glonass-K1 No.12L is a Russian navigation satellite which was launched in 2014. The second Glonass-K satellite to be launched, it is the second of two Glonass-K1 spacecraft which will serve as prototypes for the operational Glonass-K2 spacecraft.
