Soyuz 7K-T No.39
Soyuz 7K-T No.39, (also named Soyuz 18a or Soyuz 18-1 by some sources and also known as the April 5 Anomaly) was an unsuccessful launch of a crewed Soyuz spacecraft by the Soviet Union in 1975. The mission was expected to dock with the orbiting Salyut 4 space station, but due to a failure of the Soyuz launch vehicle the crew failed to make orbit. The crew consisted of commander Vasily Lazarev, and flight engineer Oleg Makarov, a civilian. Although the mission was aborted and did not accomplish its objective, the craft exceeded common space boundaries and therefore is recognized as a sub-orbital spaceflight, which the crew survived. The crew, who initially feared they had landed in China, were successfully recovered. The accident was partly disclosed by the normally secretive Soviets as it occurred during preparations for their joint Apollo-Soyuz Test Project with the United States which flew three months later. Lazarev never flew to space again and never fully recovered fr ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Salyut 4
Salyut 4 (DOS 4) (russian: Салют-4; English translation: Salute 4) was a Salyut space station launched on December 26, 1974 into an orbit with an apogee of 355 km, a perigee of 343 km and an orbital inclination of 51.6 degrees. It was essentially a copy of the DOS 3 (or Kosmos 557), and unlike its ill-fated sibling it was a complete success. Three crews attempted to make stays aboard Salyut 4 ( Soyuz 17 and Soyuz 18 docked; Soyuz 18a suffered a launch abort). The second stay was for 63 days duration, and an unmanned capsule, called Soyuz 20, remained docked to the station for three months, proving the system's long-term durability despite some deterioration of the environmental system during Soyuz 18's mission. Salyut 4 was deorbited February 2, 1977, and re-entered the Earth's atmosphere on February 3. Description Salyut 4 represented the second phase of DOS civilian space station. Although the basic design of Salyut 1 was retained, it switched to three large sol ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Soyuz 18
Soyuz 18 (russian: Союз 18, ''Union 18'') was a 1975 Soviet crewed mission to Salyut 4, the second and final crew to man the space station. Pyotr Klimuk and Vitaly Sevastyanov set a new Soviet space endurance record of 63 days and the mark for most people in space simultaneously (seven) was tied during the mission. Crew Backup crew Mission parameters *Mass: *Perigee: *Apogee: *Inclination: 51.6° *Period: 88.6 minutes Mission highlights The Soyuz 18 crew were the back-up crew for the failed Soyuz 18a mission, carried out that mission's objectives, and continued the work of the previous Soyuz 17 crew. Klimuk and Sevastyanov were launched into space on 24 May 1975 and docked with Salyut 4 two days later. The crew quickly set to performing experiments and fixing or replacing equipment. A spectrometer was repaired, a gas analyzer was replaced, and a pumping condenser in the water regeneration system was switched with a hand pump. On 29 and 30 May 1975, b ...

Earth
Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surface is made up of the ocean, dwarfing Earth's polar ice, lakes, and rivers. The remaining 29% of Earth's surface is land, consisting of continents and islands. Earth's surface layer is formed of several slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's liquid outer core generates the magnetic field that shapes the magnetosphere of the Earth, deflecting destructive solar winds. The atmosphere of the Earth consists mostly of nitrogen and oxygen. Greenhouse gases in the atmosphere like carbon dioxide (CO2) trap a part of the energy from the Sun close to the surface. Water vapor is widely present in the atmosphere and forms clouds that cover most of the planet. More solar e ...

Guidance System
A guidance system is a virtual or physical device, or a group of devices implementing a controlling the movement of a ship, aircraft, missile, rocket, satellite, or any other moving object. Guidance is the process of calculating the changes in position, velocity, altitude, and/or rotation rates of a moving object required to follow a certain trajectory and/or altitude profile based on information about the object's state of motion. A guidance system is usually part of a Guidance, navigation and control system, whereas navigation refers to the systems necessary to calculate the current position and orientation based on sensor data like those from compasses, GPS receivers, Loran-C, star trackers, inertial measurement units, altimeters, etc. The output of the navigation system, the navigation solution, is an input for the guidance system, among others like the environmental conditions (wind, water, temperature, etc.) and the vehicle's characteristics (i.e. mass, control system avail ...

Soyuz 11
Soyuz 11 (russian: link=no, Союз 11, lit=Union 11) was the only crewed mission to board the world's first space station, Salyut 1 (Soyuz 10 had soft-docked, but had not been able to enter due to latching problems). The crew, Georgy Dobrovolsky, Vladislav Volkov, and Viktor Patsayev, arrived at the space station on 7 June 1971, and departed on 29 June 1971. The mission ended in disaster when the crew capsule uncontrolled decompression, depressurised during preparations for Atmospheric entry, re-entry, killing the three-man crew. The three crew members of Soyuz 11 are the only list of spaceflight-related accidents and incidents, humans to have died in space. Crew Backup crew Original crew Crew notes The original prime crew for Soyuz 11 consisted of Alexei Leonov, Valeri Kubasov, and Pyotr Kolodin. A medical X-ray examination four days before launch suggested that Kubasov might have tuberculosis, and according to the mission rules, the prime crew was replaced wi ...

Soyuz 12
Soyuz 12 (russian: Союз 12, ''Union 12'') was a September, 1973, crewed test flight by the Soviet Union of the newly redesigned Soyuz 7K-T spacecraft that was intended to provide greater crew safety in the wake of the Soyuz 11 tragedy. The flight marked the return of the Soviets to crewed space operations after the 1971 accident. The crew capacity of the capsule had been decreased from three to two cosmonauts to allow for pressure suits to be worn during launch, re-entry and docking. It was the first time pressure suits were used for reentry since the Voskhod 2 flight. Cosmonauts Vasily Lazarev and Oleg Grigoryevich Makarov spent two days in space testing the new craft.

Cosmonaut
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 reserved for professional space travelers, the term is sometimes applied to anyone who travels into space, including scientists, politicians, journalists, and tourists. "Astronaut" technically applies to all human space travelers regardless of nationality. However, astronauts fielded by Russia or the Soviet Union are typically known instead as cosmonauts (from the Russian "kosmos" (космос), meaning "space", also borrowed from Greek). Comparatively recent developments in crewed spaceflight made by China have led to the rise of the term taikonaut (from the Mandarin "tàikōng" (), meaning "space"), although its use is somewhat informal and its origin is unclear. In China, the People's Liberation Army Astronaut Corps astronauts and thei ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Vitaly Sevastyanov
Vitaly Ivanovich Sevastyanov (russian: Вита́лий Ива́нович Севастья́нов; 8 July 1935 – 5 April 2010) was a Soviet people, Soviet astronaut, cosmonaut and an engineer who flew on the Soyuz 9 and Soyuz 18 missions. He trained as an engineer at the Moscow Aviation Institute and after graduation in 1959, joined Sergey Korolev's design bureau, where he worked on the design of the Vostok spacecraft. He also lectured at the Gagarin Cosmonaut Training Centre, Cosmonaut Training Centre, teaching the physics of spaceflight. In 1967 he commenced cosmonaut training himself. Between 15 and 24 September 1972 he Sevastyanov visited Zagreb, Yugoslavia. After two successful missions, including a two-month stay on the Salyut 4 space station, he was pulled from active flight status in 1976. He worked in ground control for the Salyut 6 station before returning to spacecraft design in the 1980s to work on the Shuttle Buran, Buran project. In 1971, he was the backup ...

Salyut 6
Salyut 6 (russian: Салют-6; lit. Salute 6), DOS-5, was a Soviet orbital space station, the eighth station of the Salyut programme. It was launched on 29 September 1977 by a Proton rocket. Salyut 6 was the first space station to receive large numbers of crewed and uncrewed spacecraft for human habitation, crew transfer, international participation and resupply, establishing precedents for station life and operations which were enhanced on Mir and the International Space Station. Salyut 6 was the first "second generation" space station, representing a major breakthrough in capabilities and operational success. In addition to a new propulsion system and its primary scientific instrument—the BST-1M multispectral telescope—the station had two docking ports, allowing two craft to visit simultaneously. This feature made it possible for humans to remain aboard for several months. Six long-term resident crews were supported by ten short-term visiting crews who typically ...

Apollo–Soyuz
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.

Kármán Line
The Kármán line (or von Kármán line ) is an attempt to define a boundary between Earth's atmosphere and outer space, and offers a specific definition set by the Fédération aéronautique internationale (FAI), an international record-keeping body for aeronautics. Defining the edge of space is important for legal and regulatory purposes since aircraft and spacecraft fall under different jurisdictions and are subject to different treaties. International law does not define the edge of space, or the limit of national airspace. The FAI defines the Kármán line as space beginning above Earth's mean sea level. This number is well above the altitude reachable by a conventional airplane and is roughly where satellites, even on very eccentric trajectories, will decay before completing a single orbit. While experts disagree on exactly where the atmosphere ends and space begins, most regulatory agencies (including the United Nations) accept the FAI Kármán line definition or someth ...
