Neutral Buoyancy Pool
A neutral buoyancy pool or neutral buoyancy tank is a pool of water in which neutral buoyancy is used to train astronauts for extravehicular activity and the development of procedures. These pools began to be used in the 1960s and were initially just recreational swimming pools; dedicated facilities would later be built. Space agencies NASA Prior to May 1960, NASA recognized the possibility of underwater neutral buoyancy simulations, and began testing their efficacy. NASA engaged Environmental Research Associates, a company based in Baltimore, to try neutral buoyancy simulations first in a pool near Langley Research Center. Visitors and other issues disturbed those efforts, so they moved the operation to a swimming pool at the McDonogh School in Maryland, where Scott Carpenter was the first astronaut to participate suited. Then, after difficult EVAs through Gemini 11 in mid-September 1966, the Manned Spacecraft Center (later renamed the Johnson Space Center) fully understood th ...

McDonnell Douglas
McDonnell Douglas was a major American aerospace manufacturing corporation and defense contractor, formed by the merger of McDonnell Aircraft and the Douglas Aircraft Company in 1967. Between then and its own merger with Boeing in 1997, it produced well-known commercial and military aircraft, such as the DC-10 airliner, the F-15 Eagle air superiority fighter, the MD-80 airliner, and the F/A-18 Hornet multirole fighter. The corporation's headquarters were at St. Louis Lambert International Airport, near St. Louis, Missouri; its subsidiary, McDonnell Douglas Technical Services Company (MDTSC), was based elsewhere in St. Louis County, Missouri. At its peak in mid-1990, McDonnell Douglas employed 132,500 people. By the end of 1992, employment had dropped to approximately 87,400.

Tsukuba Space Center
The Tsukuba Space Center (TKSC) also known by its radio callsign Tsukuba, is the operations facility and headquarters for the Japan Aerospace Exploration Agency (JAXA) located in Tsukuba Science City in Ibaraki Prefecture. The facility opened in 1972 and serves as the primary location for Japan's space operations and research programs. Japanese astronauts involved in the International Space Station are trained in part here in addition to the training they receive at the Lyndon B. Johnson Space Center, in Houston, Texas. The complex has several facilities that are used to assemble JAXA's satellites, and the Japanese Experiment Module for the International Space Station. The TKSC offers tours of the facility as well as an exhibit hall which features models of the H-II Transfer Vehicle and a full-sized mock-up of the '' Kibō'' module on the International Space Station.

Octagon
In geometry, an octagon (from the Greek ὀκτάγωνον ''oktágōnon'', "eight angles") is an eight-sided polygon or 8-gon. A '' regular octagon'' has Schläfli symbol and can also be constructed as a quasiregular truncated square, t, which alternates two types of edges. A truncated octagon, t is a hexadecagon, . A 3D analog of the octagon can be the rhombicuboctahedron with the triangular faces on it like the replaced edges, if one considers the octagon to be a truncated square. Properties of the general octagon The sum of all the internal angles of any octagon is 1080°. As with all polygons, the external angles total 360°. If squares are constructed all internally or all externally on the sides of an octagon, then the midpoints of the segments connecting the centers of opposite squares form a quadrilateral that is both equidiagonal and orthodiagonal (that is, whose diagonals are equal in length and at right angles to each other).Dao Thanh Oai (2015), "Equilate ...

Vitaly Sevastyanov
Vitaly Ivanovich Sevastyanov (russian: Вита́лий Ива́нович Севастья́нов; 8 July 1935 – 5 April 2010) was a Soviet 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 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 Buran project.

Andriyan Nikolayev
Andriyan Grigoryevich Nikolayev ( Chuvash and russian: Андриян Григорьевич Николаев; 5 September 1929 – 3 July 2004) was a Soviet cosmonaut. In 1962, aboard Vostok 3, he became the third Soviet cosmonaut to fly into space. Nikolayev was an ethnic Chuvash and is considered as the first Turkic person who flew into space. Early life Andrian Grigoryevich Nikolayev was born on September 5, 1929, in Sorseli, a village in the Chuvash region of the Volga River valley, and spent his time growing up on a collective farm. Education and career Nikolayev supported his family following the death of his father in 1944, however this was not preferred by his mother, who preferred that he earn an education. Nikolayev later entered medical school before he joined the Soviet army. During his training Nikolayev was able to maintain a very calm state during stressful situations. Nikolayev's calm made him a fair candidate for becoming a cosmonaut. His future colleague ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yuri Gagarin Cosmonaut Training Center
The Yuri A. Gagarin State Scientific Research-and-Testing Cosmonaut Training Center (GCTC; Russian: Центр подготовки космонавтов имени Ю. А. Гагарина) is a Russian training facility responsible for training cosmonauts for their space missions. It is in Star City of Moscow Oblast, a name which may refer to the facility itself or to its grounds. Formation The facility was originally known only as Military Unit 26266 or в/ч 26266, and was a secret training base for Soviet Cosmonaut candidates. The site was chosen for its proximity to Moscow and other infrastructure that would be essential for its function: Chkalovsky Airport, and the Yaroslavl railroad. The densely forested area was originally a radar range with some existing infrastructure. Military doctor Colonel Yevgeny Karpov was appointed as the first chief of the cosmonaut training centre or ''Tsentr Podgotovki Kosmonavtov'' (TsPK) on 24 February 1960. The centre was home to a ...
