N1-L3
The Soviet crewed lunar programs were a series of programs pursued by the Soviet Union to land humans on the Moon, 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 launched with the 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 until 1990 when the government allowed them to be pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
N1 (rocket)
The N1/L3 (from , "Carrier Rocket"; Cyrillic: Н1) was a super heavy-lift launch vehicle intended to deliver payloads beyond low Earth orbit. The N1 was the 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, remains the most powerful rocket stage ever flown. However, all four first stages flown failed mid-flight because a lack of static test firings meant that plumbing issues and other adverse characteristics with the large cluster of thirty engines and its complex fuel and oxidizer feeder system were not revealed earlier in development. The N1-L3 version was designed to compete with the United States Apollo program to land a person on the Moon, using a similar lunar orbit rendezvous method. The basic N1 launch vehicle had three stages, which were to carry the L3 lunar payload into low Earth orbit with two cosmonauts. The L3 contained one stage for trans-lun ...

Soyuz 7K-LOK
The Soyuz 7K-LOK, or simply LOK (russian: Лунный Орбитальный Корабль, translit=Lunniy Orbitalny Korabl meaning "Lunar Orbital Craft") was a Soviet crewed spacecraft designed to launch men from Earth to orbit the Moon, developed in parallel to the 7K-L1. The LOK would carry two cosmonauts, acting as a mother ship for the LK Lander which would land one crew member to the surface. It was part of the N1-L3 programme which also included the LK lander and the N1 rocket. Design Like the 7K-OK model, the 7K-LOK was divided into three sections, an ellipsoid Orbital Module, the "headlight"-shaped Descent Module, and a cylindrical equipment module. Like the 7K-OK, the 7K-LOK was capable of physically docking with another spacecraft, but lacked the transfer tunnel used on the Apollo (spacecraft), thus forcing the cosmonaut to make a spacewalk from the 7K-LOK's orbital module to the LK Lander using the new Krechet space suit (the predecessor to the Orlan space suits ...

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] |
Soyuz 7K-L1
The Soyuz 7K-L1 "Zond" spacecraft was designed to launch men from the Earth to circle the Moon without going into lunar orbit in the context of the Soviet crewed Moon-flyby program in the Moon race. It was based on the Soyuz 7K-OK. Several modifications reduced vehicle mass and increased circumlunar capability. The most notable modifications were the replacement of the orbital module with a support cone and a high-gain parabolic antenna, the removal of a reserve parachute, and the addition of the gyro platform and star navigation sensors for the far space navigation. The spacecraft was capable of carrying two cosmonauts. At the start of flight testing, there were serious reliability problems with the new Proton rocket, the 7K-L1, and the Soyuz 7K-OK that the L1 was based on. History Chief Designer Sergei Korolev had originally envisioned a crewed lunar spacecraft launched in pieces by R-7 boosters and assembled in Earth orbit.

Lunar Base
A moonbase is a facility on the surface of the Moon, enabling human activity on the Moon. As such, it is different from a lunar space station in orbit around the Moon, like the planned Lunar Gateway of the Artemis program. Moonbases can be for robotic or human use, in both cases not necessarily including lunar habitation facilities. A base might be a step towards colonization. Missions to the Moon have so far realized only temporary single-mission bases, (Tranquility Base being the first), as well as some small permanent installations. Plans for establishing facilities on the Moon that could enable sustained human activity at the Moon have been proposed and are actively pursued nationally and increasingly internationally by space agencies. Chinese concepts In 2020, China proposed the International Lunar Research Station (ILRS), a somewhat similar proposal to the Moon Village, with Roscosmos and ESA showing interest. The first steps toward establishing the ILRS will be take ... [...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 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 An astronaut (from the Ancient Greek (), meaning 'star', and (), meaning 'sailor') is a person trained, equipped, and deployed by a human spaceflight program to serve as a commander or crew member aboard a spacecraft. Although generally r ... 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: Firs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apollo 8
Apollo 8 (December 21–27, 1968) was the first crewed spacecraft to leave low Earth orbit and the first human spaceflight to reach the Moon. The crew orbited the Moon ten times without landing, and then departed safely back to Earth. These three astronauts—Frank Borman, James Lovell, and William Anders—were the first humans to personally witness and photograph the far side of the Moon and an Earthrise. Apollo 8 launched on December 21, 1968, and was the second crewed spaceflight mission flown in the United States Apollo space program after Apollo7, which stayed in Earth orbit. Apollo8 was the third flight and the first crewed launch of the Saturn V rocket, and was the first human spaceflight from the Kennedy Space Center, located adjacent to Cape Kennedy Air Force Station in Florida. Originally planned as the second crewed Apollo Lunar Module and command module test, to be flown in an elliptical medium Earth orbit in early 1969, the mission profile was changed in ...

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 ''Encyclo ...

Space Race
The Space Race was a 20th-century competition between two Cold War rivals, the United States and the Soviet Union, to achieve superior spaceflight capability. It had its origins in the ballistic missile-based nuclear arms race between the two nations following World War II. The technological advantage demonstrated by spaceflight achievement was seen as necessary for national security, and became part of the symbolism and ideology of the time. The Space Race brought pioneering launches of artificial satellites, robotic space probes to the Moon, Venus, and Mars, and human spaceflight in low Earth orbit and ultimately to the Moon. Public interest in space travel originated in the 1951 publication of a Soviet youth magazine and was promptly picked up by US magazines. The competition began on July 30, 1955 when the United States announced its intent to launch artificial satellites for the International Geophysical Year. Four days later, the Soviet Union responded by declaring ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proton Rocket
Proton (Russian: Протон) (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 as of 2022, making it one of the most successful heavy boosters in the history of spaceflight. The components of all Protons are manufactured at 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 amo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cislunar
Outer space, commonly shortened to space, is the expanse that exists beyond Earth and its atmosphere and between celestial bodies. Outer space is not completely empty—it is a near-perfect vacuum containing a low density of particles, predominantly a plasma of hydrogen and helium, as well as electromagnetic radiation, magnetic fields, neutrinos, dust, and cosmic rays. The baseline temperature of outer space, as set by the background radiation from the Big Bang, is . The plasma between galaxies is thought to account for about half of the baryonic (ordinary) matter in the universe, having a number density of less than one hydrogen atom per cubic metre and a kinetic temperature of millions of kelvins. Local concentrations of matter have condensed into stars and galaxies. Studies indicate that 90% of the mass in most galaxies is in an unknown form, called dark matter, which interacts with other matter through gravitational but not electromagnetic forces. Observations suggest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
