Soviet Crewed Lunar Programs
The Soviet crewed lunar programs were a series of programs pursued by the Soviet Union to Moon landing, land humans on the Moon, Space Race, in competition with the United States Apollo program. The Soviet government publicly denied participating in such a competition, but secretly pursued two programs in the 1960s: crewed lunar flyby missions using Soyuz 7K-L1 (Zond) spacecraft launched with the Proton-K rocket, and a crewed lunar landing using Soyuz 7K-LOK and LK (spacecraft), LK spacecraft launched with the N1 (rocket), N1 rocket. Following the dual American successes of the first crewed lunar orbit on 24–25 December 1968 (Apollo 8) and the first Moon landing on July 20, 1969 (Apollo 11), and a series of catastrophic N1 failures, both Soviet programs were eventually brought to an end. The Proton-based Zond program was canceled in 1970, and the N1-L3 program was ''de facto'' terminated in 1974 and officially canceled in 1976. Details of both Soviet programs were kept secret ...

Soviet Union
The Union of Soviet Socialist Republics. (USSR), commonly known as the Soviet Union, was a List of former transcontinental countries#Since 1700, transcontinental country that spanned much of Eurasia from 1922 until Dissolution of the Soviet Union, it dissolved in 1991. During its existence, it was the list of countries and dependencies by area, largest country by area, extending across Time in Russia, eleven time zones and sharing Geography of the Soviet Union#Borders and neighbors, borders with twelve countries, and the List of countries and dependencies by population, third-most populous country. An overall successor to the Russian Empire, it was nominally organized as a federal union of Republics of the Soviet Union, national republics, the largest and most populous of which was the Russian SFSR. In practice, Government of the Soviet Union, its government and Economy of the Soviet Union, economy were Soviet-type economic planning, highly centralized. As a one-party state go ...

N-1 Rocket
The N1 (from , "Carrier Rocket"; Cyrillic: En (Cyrillic), Н1) was a super heavy-lift launch vehicle intended to deliver payloads beyond low Earth orbit. The N1 was the Soviet Union, Soviet counterpart to the US Saturn V and was intended to enable crewed travel to the Moon and beyond, with studies beginning as early as 1959. Its first stage, Block A, was the most powerful multistage rocket, rocket stage ever flown for over 50 years, with the record standing until SpaceX Starship, Starship's SpaceX Starship integrated flight test 1, first integrated flight test. However, each of the four attempts to launch an N1 failed in flight, with the second attempt resulting in the vehicle crashing back onto its launch pad shortly after liftoff. Adverse characteristics of the large cluster of thirty engines and its complex fuel and oxidizer feeder systems were not revealed earlier in development because static test firings had not been conducted. The N1-L3 version was designed to compete wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

R-56 (rocket)
The R-56 were five proposed rockets developed by the OKB-586 design bureau under Mikhail Yangel. No formal terms for the five different designs have been discovered resulting in Bart Hendrickx writing in the Journal of the British Interplanetary Society referring to the initial two designs as the Small and Big versions. Hendrickx referred to the later three designs as “Monoblock”, “first polyblock” (similar to the Big R-56) and “second polyblock” (similar to the Small R-56). The monoblock version was considered for use in the Soviet lunar program. History The idea for the R-56 seems to have comes from a desire to build a missile that could carry Tsar Bomba type nuclear weapons. By February 1962 the concept was described in a presentation to Nikita Khrushchev as being an ICBM suitable for 50 tonne weapons as well as being able to launch space stations. Formal design work, initially mainly focusing on the small R-56, took place between April 1962 and June 1964. By this p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LK-700
LK-700 was a Soviet direct ascent lunar lander program proposed in 1964. It was developed by Vladimir Chelomey as an alternative to the N1-L3 The Soviet crewed lunar programs were a series of programs pursued by the Soviet Union to Moon landing, land humans on the Moon, Space Race, in competition with the United States Apollo program. The Soviet government publicly denied participat ... program. It was also a further development of the LK-1 lunar flyby spacecraft. It would have been launched using the proposed UR-700 rocket (related to the Proton rocket) with a crew of three cosmonauts on a direct flight to the lunar surface and back. The direct landing approach would allow the Soviets to land anywhere on the moon's nearside. The program was canceled in 1974. Mission profile Uncrewed flights would be followed by crewed flights. The proposed schedule was: * May 1972: First UR-700/LK-700 uncrewed launch. Subsequent launches in November 1972 and April 1973. * April 1973: ...

UR-700
The Universal Rocket or ''UR'' family of missiles and carrier rockets is a Russian, previously Soviet rocket family. Intended to allow the same technology to be used in all Soviet rockets, the UR is produced by the Khrunichev State Research and Production Space Center. Several variants were originally planned, of which only three flew, and only two of which entered service. In addition, the cancelled UR-500 ICBM formed the basis for the Proton carrier rocket. UR-100 The UR-100 and its variants (e.g. UR-100N) were the standard small ICBM of the Soviet Union during the Cold War. Only the UR-100N (NATO reporting designation: SS-19 Stiletto) remains in active duty, with 20–30 missiles operational. The Strela and Rokot carrier rockets are based on the UR-100N. A number of UR-100Ns have been earmarked for use as launch vehicles for the Avangard maneuverable reentry vehicle. UR-200 The UR-200 was intended to be a larger ICBM that could also be used as a carrier rocket. Nine test fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LK-1
LK-1 was a projected Soviet crewed lunar flyby spacecraft. It would be launched on a three-stage Proton launch vehicle. The project started in 1962 under the lead engineer Vladimir Chelomey, with the first flight planned for 1967. The LK-1 had its origin in several early 1960s spacecraft projects under the generic names of ''kosmoplans'' and ''raketoplans''. In 1965 the project was cancelled in favour of the Soyuz 7K-L1 spacecraft. Further developments came as the LK-700 direct-descent lunar lander program. Configuration The spacecraft consisted of the following modules: * ADU Emergency Engine Unit * VA Capsule (crew module) * PAB Equipment-Rocket System Block (service module) * RB Translunar Injection Stage Characteristics * Crew Size: 2 * Spacecraft delta v: 3,300 m/s * Electric System: 2.00 average kW. * Gross mass: 17,000 kg * Un-fuelled mass: 4,000 kg * Height: 5.20 m * Span: 7.27 m External links *Encyclopedia Astronautica The ''Encycl ...

Proton Rocket
Proton (, formal designation: UR-500) is an expendable launch system used for both commercial and Russian government space launches. The first Proton rocket was launched in 1965. Modern versions of the launch system are still in use , making it one of the most successful heavy boosters in the history of spaceflight. The components of all Protons are manufactured in the Khrunichev State Research and Production Space Center factory in Moscow and Chemical Automatics Design Bureau in Voronezh, then transported to the Baikonur Cosmodrome, where they are assembled at Site 91 to form the launch vehicle. Following payload integration, the rocket is then brought to the launch pad horizontally by rail, and raised into vertical position for launch. As with many Soviet rockets, the names of recurring payloads became associated with the launch vehicle itself. The moniker "Proton" originates from a series of similarly named scientific satellites, which were among the rocket's first payloads ...

Vladimir Chelomei
Vladimir Nikolayevich Chelomey or Chelomei (, ; 30 June 1914 – 8 December 1984) was a Soviet engineer and designer in the missile program of the former Soviet Union. He invented the first Soviet pulse jet engine and was responsible for developing the world's first anti-ship cruise missiles and the ICBM program of the Soviet Union such as the UR-100, UR-200, UR-500 and UR-700. Early life Chelomey was born to a Ukrainian family in Siedlce, Lublin Governorate, Russian Empire (now Poland). At the age of three months, his family fled to Poltava, Ukraine, when the Eastern Front of World War I came close to Siedlce. When Chelomey was 12 years old, the family moved again to Kyiv. In 1932, Chelomey was admitted to the Kyiv Polytechnic Institute (later the basis of Kyiv Aviation Institute), where he showed himself as a student with outstanding talent. In 1936, his first book ''Vector Analysis'' was published. Studying at the institute, Chelomey also attended lectures on mathema ...

R-7 (rocket Family)
The R-7 () rocket family is a series of launch vehicles descended from the Soviet R-7 Semyorka, developed in the 1950s as the world's first intercontinental ballistic missile (ICBM). While the R-7 proved impractical as a weapon, it became a cornerstone of the Soviet and subsequent Russian space programs. Over time, its design was largely standardized into the Soyuz rocket, which continues to operate in its modernized form, the Soyuz-2. More R-7 rockets have been launched than any other family of orbital rockets. Background The R-7, developed by OKB-1 in Kaliningrad, a Soviet design bureau led by rocket pioneer Sergey Korolyov, was the world's first intercontinental ballistic missile (ICBM). Initially designed to deliver nuclear warheads to American targets, it was first successfully tested on 21 August 1957. The R-7's basic design comprises a central core stage (Block A) and four strap-on boosters (Block B, V, G, and D), fueled by refined kerosene ( RG-1), mixed with cryo ...
