Apollo–Soyuz Test Project
Apollo–Soyuz was the first crewed international space mission, carried out jointly by the United States and the Soviet Union in July 1975. Millions of people around the world watched on television as a United States Apollo spacecraft docked with a Soviet Soyuz capsule. The project, and its handshake in space, was a symbol of détente between the two superpowers during the Cold War. The mission was officially known as the Apollo–Soyuz Test Project (ASTP; russian: Экспериментальный полёт «Союз» – «Аполлон» (ЭПАС), translit=Eksperimentalniy polyot Soyuz–Apollon (EPAS), lit=Experimental flight Soyuz-Apollo, and commonly referred to in the Soviet Union as Soyuz–Apollo; the Soviets officially designated the mission as Soyuz 19). The unnumbered American vehicle was left over from the canceled Apollo missions, and was the last Apollo module to fly. The three American astronauts, Thomas P. Stafford, Vance D. Brand, and Deke Slayt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown m ...

Soviet Armed Forces
The Soviet Armed Forces, the Armed Forces of the Soviet Union and as the Red Army (, Вооружённые Силы Советского Союза), were the armed forces of the Russian SFSR (1917–1922), the Soviet Union (1922–1991), and the Bolshevik Party from their beginnings in the Russian Civil War of 1917–1923 to the collapse of the USSR in 1991. In May 1992, Russian President Boris Yeltsin issued decrees forming the Russian Armed Forces, which subsumed much of the Soviet Armed Forces. Much of the former Soviet Armed Forces in the other 14 Soviet republics gradually came under those republics' control. According to the all-union military service law of September 1925, the Soviet Armed Forces consisted of the Ground Forces, the Air Forces, the Navy, the State Political Directorate (OGPU), and the convoy guards. The OGPU was later made independent and amalgamated with the NKVD in 1934, and thus its Internal Troops were under the joint management of the Defence ...

Détente
Détente (, French: "relaxation") is the relaxation of strained relations, especially political ones, through verbal communication. The term, in diplomacy, originates from around 1912, when France and Germany tried unsuccessfully to reduce tensions. The term is often used to refer to a period of general easing of the geopolitical tensions between the Soviet Union and the United States during the Cold War. It began in 1969, as a core element of the foreign policy of US President Richard Nixon, in an effort to avoid nuclear escalation. The Nixon administration promoted greater dialogue with the Soviet government, including regular summit meetings and negotiations over arms control and other bilateral agreements. Détente was known in Russian as разрядка (''razryadka''), loosely meaning "relaxation of tension". Summary of Cold War détente The period was characterized by the signing of treaties such as SALT I and the Helsinki Accords. Another treaty, SALT II, wa ...

Soyuz (spacecraft)
Soyuz () is a series of spacecraft which has been in service since the 1960s, having made more than 140 flights. It was designed for the Soviet space program by the Korolev Design Bureau (now Energia). The Soyuz succeeded the Voskhod spacecraft and was originally built as part of the Soviet crewed lunar programs. It is launched on a Soyuz rocket from the Baikonur Cosmodrome in Kazakhstan. Between the 2011 retirement of the Space Shuttle and the 2020 demo flight of SpaceX Crew Dragon, the Soyuz served as the only means to ferry crew to or from the International Space Station, for which it remains heavily used. Although China did launch crewed Shenzhou flights during this time, none of them docked with the ISS. History The first Soyuz flight was uncrewed and started on 28 November 1966. The first Soyuz mission with a crew, Soyuz 1, launched on 23 April 1967 but ended with a crash due to a parachute failure, killing cosmonaut Vladimir Komarov. The following flight was ...

Docking And Berthing Of Spacecraft
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. ''Docking'' specifically refers to joining of two separate free-flying space vehicles. ''Berthing'' refers to mating operations where a passive module/vehicle is placed into the mating interface of another space vehicle by using a robotic arm. Because the modern process of un-berthing requires more crew labor and is time-consuming, berthing operations are unsuited for rapid crew evacuations in the event of an emergency. History Docking Spacecraft docking capability depends on space rendezvous, the ability of two spacecraft to find each other and station-keep in the same orbit. This was first developed by the United States for Project Gemini. It was planned for the crew of Gemini 6 to rendezvous and manually dock under the command of Wally Schirra, with an uncrewed Agena Target Vehicle in October 1965, but ...

Space Exploration
Space exploration is the use of astronomy and space technology to explore outer space. While the exploration of space is carried out mainly by astronomers with telescopes, its physical exploration though is conducted both by uncrewed robotic space probes and human spaceflight. Space exploration, like its classical form astronomy, is one of the main sources for space science. While the observation of objects in space, known as astronomy, predates reliable recorded history, it was the development of large and relatively efficient rockets during the mid-twentieth century that allowed physical space exploration to become a reality. The world's first large-scale experimental rocket program was Opel-RAK under the leadership of Fritz von Opel and Max Valier during the late 1920s leading to the first crewed rocket cars and rocket planes, which paved the way for the Nazi era V2 program and US and Soviet activities from 1950 onwards. The Opel-RAK program and the spectacular p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Soyuz Programme
The Soyuz programme ( , ; russian: link=no, Союз , meaning "Union") 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 astronaut, cosmonaut on the Moon. It was the third Soviet human spaceflight programme after the Vostok programme, Vostok (1961–1963) and Voskhod programme, Voskhod (1964–1965) programmes. The programme consists of the Soyuz (spacecraft), Soyuz capsule and the Soyuz (rocket family), Soyuz rocket and is now the responsibility of the Russian Federation, Russian Roscosmos. After the retirement of the Space Shuttle in 2011, Soyuz was the only way for humans to get to the International Space Station (ISS) until 30 May 2020, when Crew Dragon flew to the ISS for the first time with astronauts.

Apollo 17
Apollo 17 (December 7–19, 1972) was the final mission of NASA's Apollo program, the most recent time humans have set foot on the Moon or traveled beyond low Earth orbit. Commander Gene Cernan and Lunar Module Pilot Harrison Schmitt walked on the Moon, while Command Module Pilot Ronald Evans orbited above. Schmitt was the only professional geologist to land on the Moon; he was selected in place of Joe Engle, as NASA had been under pressure to send a scientist to the Moon. The mission's heavy emphasis on science meant the inclusion of a number of new experiments, including a biological experiment containing five mice that was carried in the command module. Mission planners had two primary goals in deciding on the landing site: to sample lunar highland material older than that at Mare Imbrium and to investigate the possibility of relatively recent volcanic activity. They therefore selected Taurus–Littrow, where formations that had been viewed and pictured from orbi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
