Soyuz-L
The Soyuz-L (russian: Союз, meaning "union"), GRAU index 11A511L was a Soviet expendable carrier rocket designed by OKB-1 and manufactured by State Aviation Plant No. 1 in Samara, Russia. It was created to test the LK lunar lander in low Earth orbit, as part of the Soviet lunar programme. The Soyuz-L was a derivative of the original Soyuz rocket featuring the reinforced first stage and boosters supporting the Molniya-M's third stage, so that it could carry a more massive payload. A larger payload fairing was also fitted, to accommodate the LK spacecraft. The Soyuz-L was only launched three times between 1970 and 1971, all successful. The later Soyuz-U The Soyuz-U launch vehicle was an improved version of the original Soyuz rocket. Soyuz-U was part of the R-7 family of rockets based on the R-7 Semyorka missile. Members of this rocket family were designed by the TsSKB design bureau and cons ... used a similar configuration to the Soyuz-L. References 1970 in s ...

1971 In Spaceflight
1971 saw the last three known deaths of cosmonauts of the Soviet space program and the only deaths in space. Their mission was to man humanity's first space station. The experimental bay door failed to separate so the first crew failed to dock and second crew were killed on re-entry. 1971 also saw the launch of the first and only British satellite on top of a British rocket after that success the program was cancelled. __TOC__ Launches , colspan="8", January , - , colspan="8", February , - , colspan="8", March , - , colspan="8", April , - , colspan="8", May , - , colspan="8", June , - , colspan="8", July , - , colspan="8", August , - , colspan="8", September , - , colspan="8", October , - , colspan="8", November , - , colspan="8", December , - Launches from the Moon ...

Soyuz (rocket)
The Soyuz (russian: Союз, meaning "union", GRAU index 11A511) was a Soviet expendable carrier rocket designed in the 1960s by OKB-1 and manufactured by State Aviation Plant No. 1 in Kuybyshev, Soviet Union. It was commissioned to launch Soyuz spacecraft as part of the Soviet human spaceflight program, first with 8 uncrewed test flights, followed by the first 19 crewed launches. The original Soyuz also propelled four test flights of the improved Soyuz 7K-T capsule between 1972 and 1974. In total it flew 30 successful missions over 10 years and suffered two failures. The Soyuz 11A511 type, a member of the R-7 family of rockets, first flew in 1966. Derived from the Voskhod 11A57 type, It was a two-stage rocket, with four liquid-fuelled strap-on boosters clustered around the first stage, with a Block I second stage. The first four test launches were all failures, but eventually it worked. The new, uprated core stage and strap-ons became standard for all R-7 derived launch ...

R-7 (rocket Family)
The R-7 family of rockets (russian: Р-7) is a series of rockets, derived from the Soviet R-7 Semyorka, the world's first ICBM. More R-7 rockets have been launched than any other family of large rockets. When Soviet nuclear warheads became lighter, the R-7 turned out to be impractical as a ballistic missile, and there were no other heavy payloads with a military application. However, long-term development has made the rockets useful in the Soviet, and later, Russian space programmes. Their purpose shifted primarily to launching satellites, probes, manned and unmanned spacecraft, and other non-threatening payloads. The R-7 family consists of both missiles and orbital carrier rockets. Derivatives include the Vostok, Voskhod and Soyuz rockets, which as of 2022 have been used for all Soviet, and later Russian human spaceflights. The type has a unique configuration where four break-away liquid-fueled engines surround a central core. The core acts as, in effect, a "second stage" af ...

Baikonur Cosmodrome Site 31
Baikonur Site 31, also known as Site 31/6 at the Baikonur Cosmodrome, in Kazakhstan, is a launch site used by derivatives of the R-7 Semyorka missile. From 2011 onwards, it was supposed to be the launch site for crewed Soyuz missions to the International Space Station, when launches switched from the Soyuz-FG launch vehicle to the Soyuz-2, which was unable to use the launch pad at Site 1/5. However, Site 1/5 has undergone modifications that allow the crewed ISS missions to be launched from it. Only a few crewed missions to the International Space Station (ISS) are launched from Site 31/6 (Soyuz TMA-06M, Soyuz TMA-15M, Soyuz MS-02), when Site 1/5 is unavailable. It was first used on 14 January 1961, for an R-7A ICBM test mission. It is currently used for commercial Soyuz-FG/Fregat missions, and Soyuz-2 launches. In the 1970s and early 1980s, several crewed missions were launched from the site. See also * Gagarin's Start Gagarin's Start (russian: Гагаринс ...

LK (spacecraft)
The LK (russian: ЛК, from russian: Лунный корабль, Lunniy korabyl, lunar craft; GRAU index: 11F94) was a lunar module ( lunar lander designed for human spaceflight) 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 (including several launch failures), 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. The N1-L3 flight plan Sergei Korolev, the lead Soviet rocket engineer and spacecraft designer during the 1950s and 1960s, planned to adopt the same lunar orbit rendezvous concept as seen in the Apollo programme. The lunar expedition spacecr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RD-0110
The RD-0110 (or RO-8 , RD-0108 , RD-461 ) is a rocket engine burning liquid oxygen and kerosene in a gas generator combustion cycle. It has four fixed nozzles and the output of the gas generator is directed to four secondary vernier nozzles to supply vector control of the stage. It has an extensive flight history with its initial versions having flown more than 57 years ago (as of February 2018). History OKB-154 of S.A. Kosberg was tasked with developing an engine for the unmanned Molniya Block-I stage. Thus, the RD-0107 was developed in the 1960 to 1961 period, based on the RD-0106 (GRAU Index: 8D715) engine that powered the SS-8 Sasin ICBM, also designed by OKB-154. It also leveraged the experience in the field from the Vostok Block-E RD-0105/RD-0109 development. The engine had its debut flight on October 10, 1960, and the last Molniya flight was on October 22, 1967. For the crewed carrying Voskhod Block-I, a version of the engine that complied with the human rating 3K Reg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carrier Rocket
A launch vehicle or carrier rocket is a rocket designed to carry a payload (spacecraft or satellites) from the Earth's surface to outer space. Most launch vehicles operate from a launch pad, launch pads, supported by a missile launch control center, launch control center and systems such as vehicle assembly and fueling. Launch vehicles are engineered with advanced aerodynamics and technologies, which contribute to large operating costs. An orbital spaceflight, orbital launch vehicle must lift its payload at least to the boundary of space, approximately and accelerate it to a horizontal velocity of at least . Suborbital spaceflight, Suborbital vehicles launch their payloads to lower velocity or are launched at elevation angles greater than horizontal. Practical orbital launch vehicles are multistage rockets which use chemical propellants such as Solid-propellant rocket, solid fuel, liquid hydrogen, kerosene, liquid oxygen, or Hypergolic propellants. Launch vehicles are cla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Low Earth Orbit
A low Earth orbit (LEO) is an orbit around Earth with a period of 128 minutes or less (making at least 11.25 orbits per day) and an eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, with an altitude never more than about one-third of the radius of Earth. The term ''LEO region'' is also used for the area of space below an altitude of (about one-third of Earth's radius). Objects in orbits that pass through this zone, even if they have an apogee further out or are sub-orbital, are carefully tracked since they present a collision risk to the many LEO satellites. All crewed space stations to date have been within LEO. From 1968 to 1972, the Apollo program's lunar missions sent humans beyond LEO. Since the end of the Apollo program, no human spaceflights have been beyond LEO. Defining characteristics A wide variety of sources define LEO in terms of altitude. The altitude of an object in an elliptic orbit can vary significantly along the orbit. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1970 In Spaceflight
Japan and China each launched their first satellites in 1970, bringing the total number of nations with independent launch capability to five. Apollo 13 was launched; after suffering an explosion in deep space it had to circumnavigate the moon and use the LM as a life boat. Apollo 13 was a successful disaster in which the crew survived. The Soviet space program continued its Luna program with Luna 17, which delivered the robotic Lunokhod 1 rover to the lunar surface, and Luna 16, which achieved the first uncrewed lunar sample return A sample-return mission is a spacecraft mission to collect and return samples from an extraterrestrial location to Earth for analysis. Sample-return missions may bring back merely atoms and molecules or a deposit of complex compounds such as lo ....

Soyuz-U
The Soyuz-U launch vehicle was an improved version of the original Soyuz rocket. Soyuz-U was part of the R-7 family of rockets based on the R-7 Semyorka missile. Members of this rocket family were designed by the TsSKB design bureau and constructed at the Progress factory in Samara, Russia (now a united company, TsSKB-Progress). The first Soyuz-U flight took place on 18 May 1973, carrying as its payload Kosmos 559, a Zenit military surveillance satellite. The final flight of a Soyuz-U rocket took place on 22 February 2017, carrying Progress MS-05 to the International Space Station. Soyuz-U was in use continuously for almost 44 years. Production of R-7 derived launch vehicles peaked in the late 1970s-early 1980s at 55–60 a year. Soyuz-U held the world record of highest launch rate in a year in 1979 with 47 flights until this was beaten by SpaceX's Falcon 9 in 2022. Over its operational lifetime, the Soyuz-U variant flew a total of 786 missions, another world record. Soyuz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Encyclopedia Astronautica
The ''Encyclopedia Astronautica'' is a reference web site on space travel. A comprehensive catalog of vehicles, technology, astronauts, and flights, it includes information from most countries that have had an active rocket research program, from Robert Goddard to the NASA Space Shuttle and the Soviet Buran programme. Founded in 1994 and maintained for most of its existence by space enthusiast and author Mark Wade. He has been collecting such information for most of his life. Between 1996 and 2000 the site was hosted by ''Friends and Partners in Space''. The site is no longer updated or maintained and is now considered as partially unreliable. Although it contains a great deal of information, not all of it is correct. Reception and accolades The American Astronautical Society gave the site the Ordway Award for Sustained Excellence in Spaceflight History which "recognizes exceptional, sustained efforts to inform and educate on spaceflight and its history through one or more med ...
