The Buran programme was an attempt by the Soviet Union to construct an orbital spaceplane to perform similar functions to the Space Shuttle. Similar to the Space Shuttle programme, an aerodynamic prototype and a number of operational spacecraft were planned for the Buran programme, [1] which were known as "Buran-class orbiters".
The aerodynamic testbed OK-GLI was constructed in 1984 to test the in-flight properties of the Buran design. Unlike the American prototype Enterprise , OK-GLI had four AL-31 turbofan engines fitted, meaning it was able to fly under its own power. [2]
The list does not include taxi tests without takeoffs. All of these missions were landed at the Gromov Flight Research Institute test base.

The first operational orbiter, Buran flew one test mission, designated 1K1, on November 15, 1988 at 6:00:00 Moscow time. [6] The spacecraft was launched uncrewed from and landed at Baikonur Cosmodrome in the Kazakh S.S.R. and flew two orbits, traveling 83,707 km (52,013 mi) in 3 hours, 25 minutes (0.14 flight days). [7] Buran never flew again; the program was cancelled shortly after the dissolution of the Soviet Union. [8] In 2002, the collapse of the hangar in which it was stored destroyed the Buran orbiter.

The Buran programme, also known as the "VKK Space Orbiter programme", was a Soviet and later Russian reusable spacecraft project that began in 1974 at the Central Aerohydrodynamic Institute in Moscow and was formally suspended in 1993. In addition to being the designation for the whole Soviet/Russian reusable spacecraft project, Buran was also the name given to orbiter 1K, which completed one uncrewed spaceflight in 1988 and was the only Soviet reusable spacecraft to be launched into space. The Buran-class orbiters used the expendable Energia rocket as a launch vehicle.
Energia was a 1980s super-heavy lift launch vehicle. It was designed by NPO Energia of the Soviet Union as part of the Buran program for a variety of payloads including the Buran spacecraft. Control system main developer enterprise was the Khartron NPO "Electropribor". The Energia used four strap-on boosters each powered by a four-chamber RD-170 engine burning kerosene/LOX, and a central core stage with four single-chamber RD-0120 (11D122) engines fueled by liquid hydrogen/LOX.
The Soyuz programme is a human spaceflight programme initiated by the Soviet Union in the early 1960s. The Soyuz spacecraft was originally part of a Moon landing project intended to put a Soviet cosmonaut on the Moon. It was the third Soviet human spaceflight programme after the Vostok (1961–1963) and Voskhod (1964–1965) programmes.
Zenit is a family of space launch vehicles designed by the Yuzhnoye Design Bureau in Dnipro, Ukraine, which was then part of the Soviet Union. Zenit was originally built in the 1980s for two purposes: as a liquid rocket booster for the Energia rocket and, equipped with a second stage, as a stand-alone middle-weight launcher with a payload greater than the 7 tonnes of the Soyuz but smaller than the 20 tonnes payload of the Proton. The last rocket family developed in the USSR, the Zenit was intended as an eventual replacement for the dated Soyuz and Proton families, and it would employ propellants which were safer and less toxic than the Proton's nitrogen tetroxide/UDMH mix. Zenit was planned to take over crewed spaceship launches from Soyuz, but these plans were abandoned after the dissolution of the Soviet Union in 1991.
Soyuz T-12 was the seventh crewed spaceflight to the Soviet space station Salyut 7. The name "Soyuz T-12" is also the name of the spacecraft used to launch and land the mission's three-person crew. The mission occurred in July 1984, during the long-duration expedition Salyut 7 EO-3. During the mission, crew member Svetlana Savitskaya became the first woman to ever perform a spacewalk, and the potential Buran space shuttle pilot, Igor Volk, was given spaceflight experience. Unlike many Soyuz visiting missions, the Soyuz lifeboats were not swapped, and the crew returned to Earth in the same spacecraft in which they launched.
Anatoly Semyonovich Levchenko was a Soviet cosmonaut in the Buran programme.
Igor Petrovich Volk was a Russian test pilot and former Soviet cosmonaut in the Buran programme.
The Polyus spacecraft, also known as Polus, Skif-DM, GRAU index 17F19DM, was a prototype Soviet orbital weapons platform designed to destroy Strategic Defense Initiative satellites with a megawatt carbon-dioxide laser. It had a Functional Cargo Block derived from a TKS spacecraft to control its orbit and it could launch test targets to demonstrate the fire control system.
2K, often erroneously referred to as Ptichka, is the second Buran-class orbiter, produced as part of the Soviet/Russian Buran programme. Although 2K was the closest to being completed of any of the Buran-class orbiters, it was never finished. The program was officially cancelled in 1993, at which point the shuttle was 95-97% complete. The proposed official name for 2K was Burya.
Blok D is an upper stage used on Soviet and later Russian expendable launch systems, including the N1, Proton-K and Zenit.
The terms Androgynous Peripheral Attach System (APAS), Androgynous Peripheral Assembly System (APAS) and Androgynous Peripheral Docking System (APDS) are used interchangeably to describe a Russian family of spacecraft docking mechanisms, and are also sometimes used as generic names for any docking system in that family. A system similar to APAS-89/95 is used by the Chinese Shenzhou spacecraft.
The Buran cruise missile, designation M-40 (М-40) sometimes referred to as RSS-40, was a Soviet intercontinental cruise missile by Myasishchev capable of carrying a 3,500 kg hydrogen bomb payload. The project was canceled before flight tests began. It is unrelated to the later Buran reusable orbiter.
Buran was the first spaceplane to be produced as part of the Soviet/Russian Buran program. Buran completed one uncrewed spaceflight in 1988, and was destroyed in 2002 due to the collapse of its storage hangar. The Buran-class orbiters used the expendable Energia rocket, a class of super heavy-lift launch vehicle. Besides describing the first operational Soviet/Russian shuttle orbiter, "Buran" was also the designation for the entire Soviet/Russian spaceplane project and its flight articles, which were known as "Buran-class orbiters".
The OK-GLI, also known as Buran Analog BTS-02, was a test vehicle in the Buran programme. It was constructed in 1984, and was used for 25 test flights between 1985 and 1988 before being retired. It is now an exhibit at the Technik Museum Speyer in Germany.
The Soviet RD-0120 (also designated 11D122) was the Energia core rocket engine, fueled by LH2/LOX, roughly equivalent to the Space Shuttle Main Engine (SSME). These were attached to the Energia core rather than the orbiter, so were not recoverable after a flight, but created a more modular design (the Energia core could be used for a variety of missions besides launching the shuttle). The RD-0120 and the SSME have both similarities and differences. The RD-0120 achieved a slightly higher specific impulse and combustion chamber pressure with reduced complexity and cost (but it was single-use), as compared to the SSME. It uses a fuel-rich staged combustion cycle and a single shaft to drive both the fuel and oxidizer turbopumps. Some of the Russian design features, such as the simpler and cheaper channel wall nozzles, were evaluated by Rocketdyne for possible upgrades to the SSME. It achieved combustion stability without the acoustic resonance chambers that the SSME required.
Matus Ruvimovich Bisnovat was a Soviet aircraft and missile designer. Bisnovat attended the Moscow Aviation Institute (MAI), graduating in 1931. In 1938, he headed a research team in Central Aero-Hydrodynamics Institute TsAGI, Zhukovsky, where several high-speed experimental airplanes were developed, the SK-1, SK-2 and SK-3.
Mir EO-5 was the 5th long duration expedition to the space station Mir, which lasted from September 1989 to February 1990. The two person crew was launched and landed in the spacecraft Soyuz TM-8, which remained docked to Mir throughout the mission. The crew are often referred to as the Soyuz TM-8 crew.
Docking and berthing of spacecraft is the joining of two space vehicles. This connection can be temporary, or partially permanent such as for space station modules.
The LKS was a Soviet Union spaceplane project led by Vladimir Chelomey in response to the United States Space Shuttle. The LKS was smaller and cheaper than its American counterpart, but was ultimately discarded in favor of the larger Buran. Claiming that the Buran project was too big, heavy, and expensive for Russia to complete, Chelomey designed the LKS in 1979. He ordered the construction of a full-scale mock-up, as a way to further stimulate interest. The project was never fully sanctioned however, and in 1982, Chelomey was officially ordered by the Soviet government to stop any further development. In March 1983, Chelomey made yet another attempt to obtain permission to build the LKS to repel US Intercontinental ballistic missiles. This too proved futile. In 1991 the mock-up was destroyed, possibly by sabotage.
Oleg Grigoriyevich Kononenko was a member of Soviet cosmonaut group LII-1. He was born in the village of Samarskoye, in Rostov, Russia, then part of the Soviet Union. He graduated from Zhukovsky Air Force Institute in 1975. On July 12, 1977, he was selected for cosmonaut training as a pilot of the Buran space shuttle. He survived an aircraft ejection on the Soviet aircraft carrier Minsk on December 27, 1979. Kononenko was married three times and had four children. He was killed on September 8, 1980, in the crash of a Yakovlev Yak-38 VTOL fighter on takeoff from the Minsk in the South China Sea.
