Tsyklon-2
The Tsyklon-2 (), also known as Tsiklon-2 and Tsyklon-M (known as SL-11 by the United States United States Department of Defense, DoD), GRAU index 11K69, was a Soviet Union, Soviet, later Ukraine, Ukrainian, orbital carrier rocket used from the 1960s to the late 2000s. The rocket had 106 launches, one suborbital and 105 orbital, with only one failure and 92 consecutive successful launches, from 27 December 1973 with the launch of Kosmos 626 to 25 June 2006 with the final flight of the Tsyklon-2, which makes this launcher most reliable within rocket launched more than 100 times. History A derivative of the R-36 (missile), R-36 ICBM, and a member of the Tsyklon family, the Tsyklon-2 made its maiden flight on 6 August 1969, and conducted 106 flights, the last one occurring on 24 June 2006. It was the most reliable Soviet/Russian carrier rocket ever used, and launched more than 100 times having failed only once, and the second most reliable carrier rocket overall, behind the Atlas ...

RD-251
The RD-250 (, GRAU index: 8D518) is the base version of a dual-nozzle family of liquid-fuel rocket engines, burning a hypergolic mixture of unsymmetrical dimethylhydrazine (UDMH) fuel with dinitrogen tetroxide () oxidizer in a gas-generator open cycle. The RD-250 was developed by OKB-456 for Yangel's PA Yuzhmash ICBM, the R-36 (8K67). Its variations were also used on the Tsyklon-2 and Tsyklon-3 launch vehicles. It was supposed to be used on the Tsyklon-4, but since the cancellation of the project it should be considered as out of production. Versions The engine has seen different versions made: * RD-250 (GRAU index: 8D518): Base engine of the family. Used on the R-36. A bundle of three RD-250 form the RD-251 cluster. * RD-250P (GRAU index: 8D518P): Improved version of the RD-250. Used on the R-36P. A bundle of three RD-250P form the RD-251P cluster. * RD-250M (GRAU index: 8D518M): Improved version of the RD-250P. Used on the R-36-O. A bundle of three RD-250M form the RD ...

Tsyklon
The Tsyklon (, "Cyclone", also known as Tsiklon), GRAU index 11K67, was a Soviet-designed expendable launch system, primarily used to put Kosmos satellites into low Earth orbit in the late-1960s. It is based on the R-36 intercontinental ballistic missile designed by Mikhail Yangel and made eight launches, with seven successes and one failure. All of its launches were conducted from LC-90 at the Baikonur Cosmodrome. It is sometimes designated Tsyklon-2A, not to be confused with the later Tsyklon-2 rocket. It was introduced in 1967 and was derived from the R-36 ICBM (NATO designation SS-9 Scarp). It was retired in 1969. It made its maiden flight on 27 October 1967. The booster's design was kept secret and no images or film clips of the complete vehicle were released to the public until after the collapse of the Soviet Union, in part because of being used exclusively for military payloads and also because it was derived from an actively serving missile system. After 1991, the pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baikonur Cosmodrome
The Baikonur Cosmodrome is a spaceport operated by Russia within Kazakhstan. Located in the Kazakh city of Baikonur, it is the largest operational space launch facility in terms of area. All Russian Human spaceflight, crewed spaceflights are launched from Baikonur. Situated in the Kazakh Steppe, some above sea level, it is to the east of the Aral Sea and north of the Syr Darya. It is close to Töretam, a station on the Trans-Aral Railway. Russia, as the official successor state to the Soviet Union, has retained control over the facility since 1991; it originally assumed this role through the post-Soviet Commonwealth of Independent States (CIS), but ratified an agreement with Kazakhstan in 2005 that allowed it to lease the spaceport until 2050. It is jointly managed by Roscosmos and the Russian Aerospace Forces. In 1955, the Ministry of Defense (Soviet Union), Soviet Ministry of Defense issued a decree and founded the Baikonur Cosmodrome. It was originally built as the chief ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

RORSAT
Upravlyaemy Sputnik Aktivnyy ( for Controlled Active Satellite), or US-A, also known in the Western world as Radar Ocean Reconnaissance Satellite or RORSAT (GRAU index 17F16K), was a series of 33 Soviet reconnaissance satellites. Launched between 1967 and 1988 to monitor NATO and merchant vessels using radar, the satellites were powered by nuclear reactors. Because a return signal from an ordinary target illuminated by a radar transmitter diminishes as the inverse of the fourth power of the distance, for the surveillance radar to work effectively, US-A satellites had to be placed in low Earth orbit. Had they used large solar panels for power, the orbit would have rapidly decayed due to drag through the upper atmosphere. Further, the satellite would have been useless in the shadow of Earth. Hence the majority of the satellites carried type BES-5 nuclear reactors fuelled by uranium-235. Normally the nuclear reactor cores were ejected into high orbit (a so-called "disposal orbit") a ...

RD-861
The RD-861 () is a Soviet liquid propellant rocket engine burning a hypergolic mixture of unsymmetrical dimethylhydrazine (UDMH) fuel with dinitrogen tetroxide () oxidizer in a gas generator combustion cycle. It has a main combustion chamber, with four vernier nozzles fed by the gas generator output. It can be reignited a single time. History When the Soviet military developed the Fractional Orbital Bombardment System, Yangel's OKB-586 proposed a new version of their R-36 ICBM, called the R-36-ORB (GRAU Index: 8K69). It incorporated an orbital warhead called OGCh (GRAU Index: 8F021), for which the RD-854 engine was developed in-house. Since the Outer Space Treaty of 1967 banned nuclear weapons in Earth orbit, but did not ban the launch systems, the Soviet Union proceeded to test their FOBS albeit without placing nuclear warheads in orbit. Versions There are three versions of this engine: * RD-854 (GRAU Index: 8D612): First developed as the third stage engine for the R-36O ...

Tsyklon-3
The Tsyklon-3, also known as Tsiklon-3 and Cyclone-3 (known as SL-14 by the United States DoD), GRAU index 11K68, was a Soviet, and subsequently Ukrainian orbital carrier rocket. Overview Tsyklon-3 launching a Meteor-3 satellite at left A derivative of the R-36 ICBM, and a member of the Tsyklon family, Tsyklon-3 made its maiden flight on 24 June 1977, and was retired on 30 January 2009. The Ukrainian-built Tsyklon rockets were retired in favour of future all-Russian carrier rockets, such as the Angara, and because they were fuelled by toxic hypergolic propellants. Successor Ukraine was developing a commercial derivative of the Tsyklon-3, the Tsyklon-4. The development of Tsyklon-4 ended in 2015 after Ukraine's development partner Brazil pulled out of the project. Tsyklon-4 never made it to launch pad. Another successor to the Tsyklon rockets, Cyclone-4M (based on Tsyklon-4 designs), is under development as of 2021 for use in the commercial market. Debris 2013 lo ...

Atlas II
Atlas II was a member of the Atlas family of launch vehicles, which evolved from the successful Atlas missile program of the 1950s. The Atlas II was a direct evolution of the Atlas I, featuring longer first-stage tanks, higher-performing engines, and the option for strap-on solid rocket boosters. It was designed to launch payloads into low Earth orbit, geosynchronous transfer orbit or geosynchronous orbit. Sixty-three launches of the Atlas II, IIA and IIAS models were carried out between 1991 and 2004; all sixty-three launches were successes, making the Atlas II a highly reliable space launch system. The Atlas line was continued by the Atlas III, used between 2000 and 2005, and the Atlas V, which is still in use . Background In May 1988, the US Air Force chose General Dynamics (now Lockheed Martin) to develop the Atlas II vehicle, primarily to launch Defense Satellite Communications System payloads under the Medium Launch Vehicle II (MLV-II) p ...
