Soyuz 7K-OK
Soyuz 7K-OK was the first generation of Soyuz spacecraft and was flown between 1967 and 1971. The 7K-OK was used for the first ferry flights to the Salyut space station program, beginning a long history of space station service that continues today with the International Space Station (ISS). , the 7K-OK is notable for the only fatalities of the Soyuz programme, with Soyuz 1 in 1967 (sole crew-member killed by parachute failure) and Soyuz 11 in 1971 (three crew killed by depressurisation during reentry). The first uncrewed automated docking in the history of spaceflight was achieved between 7K-OK spacecraft Kosmos 186 and Kosmos 188 in 1967. Additionally firsts include the first docking between two crewed spacecraft (Soyuz 4 and Soyuz 5), the longest crewed flight involving only one spacecraft (the 18-day flight of Soyuz 9 in 1970), and the first successful transfer of crew to the first space station in the history of space flight (Soyuz 11 and Salyut 1 in 1971).

Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev (Ukrainian SSR), Minsk (Byelorussian SSR), Tashkent ( Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones. The country's roots lay in the October Revolution of 1917, when the Bolsheviks, under the leadership of Vladimir Lenin, overthrew the Russian Provisional Govern ...

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 depressurised during preparations for re-entry, killing the three-man crew. The three crew members of Soyuz 11 are the only 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 with the backup crew. For Dobrovolski and Patsayev, this was to be their first space mission ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kosmos 212
Kosmos 212 (russian: Космос 212 meaning ''Cosmos 212'') was one of a series of Soviet Soyuz programme test spacecraft whose purpose was to further test and develop the passenger version. Scientific data and measurements were relayed to earth by multichannel telemetry systems equipped with space-borne memory units. Kosmos 212 and Kosmos 213 automatically docked in orbit on 15 April 1968. Both spacecraft landed on Soviet territory. Mission On 14 April 1968 at 10:00:00 GMT, the Soyuz 11A511 s/n Ya15000-09 booster and Kosmos 212 were set up at Site 31/6 of Baikonur Cosmodrome ''Baiqoñyr ğaryş ailağy'' rus, Космодром Байконур''Kosmodrom Baykonur'' , image = Baikonur Cosmodrome Soyuz launch pad.jpg , caption = The Baikonur Cosmodrome's " Gagarin's Start" Soyu ... and the planned mission could be carried out.

Kosmos 140
Kosmos 140 (russian: Космос 140 meaning ''Cosmos 140''), Soyuz 7K-OK No.3, was an uncrewed flight of the Soyuz spacecraft. It was the third attempted test flight of the Soyuz 7K-OK model, after orbital (Kosmos 133) and launch ( Soyuz 11A511) failures of the first two Soyuz spacecraft. History The follow-up to Kosmos 133 (Soyuz 7K-OK No.2), 28 November 1966, was planned for 14 December 1966 ( Soyuz 7K-OK No.1) but ended disastrously. At liftoff, the Blok A core stage of the 11A57 booster ignited, but not the strap-ons. A shutdown command was immediately sent and pad crews began to move the service towers back in place and drain the propellants. This task was completed for the core stage and strap-ons, and then about 27 minutes after the attempted launch, the launch escape system (LES) suddenly fired. Its exhaust caused the Blok I third stage propellant tanks to overheat and explode, killing one person on the ground and damaging the Soyuz and core stage/strap-ons beyond r ...

SSVP Docking System
Sistema Stykovki i Vnutrennego Perekhoda, SSVP (russian: Система стыковки и внутреннего перехода, ''System for docking and internal transfer'') is a docking standard used by Soviet and Russian spacecraft, sometimes called RDS for ''Russian Docking System''. It has been used on all variants of Soyuz other than the Soyuz 7K-L3 and early flights of the Soyuz 7K-OK, as well as Progress, TKS, ATV, and on all Soviet and Russian space stations. History SSVP was initially conceived in 1967 by the TsKBEM design bureau for use on the then-planned OIS military space station. Though OIS never flew, in 1970 the design was selected for use on the Salyut and Almaz space stations. During its first attempted use on the Soyuz 10 mission, docking was unsuccessful due to a faulty hatch, and a failure in the automatic docking system. This led to a number of redesigns to reduce damage from accidental loads. In the 1980s, SSVP was further upgraded to support docking o ...

Yevgeny Khrunov
Yevgeny Vasilyevich Khrunov (; 10 September 1933 – 20 May 2000) was a Soviet cosmonaut who flew on the Soyuz 5/ Soyuz 4 mission. Early life Yevgeny Khrunov was born on 10 September 1933 to Vasily Yegorevich and Agrafena Nikolayevna. Nicknamed “Zhenya” he had five brothers and two sisters. Khrunov's family was a farming family. Khrunov married Svetlana Sokolyuk and had a son on 13 July 1959. He was born in Prudy, Tula Oblast, Russian SFSR. Education and career Khrunov began officially being schooled in 1941. Khrunov was initially interested in pursuing farming in studies. His interest in flying would soon follow after he watched the planes during wartime. Once he graduated from primary school he enrolled at Kashira Agricultural Secondary School on scholarship and would graduate from there in 1952. His teachers regularly spoke highly of him and considered him a hard working student. In 1952 Khrunov was also drafted into the Soviet Army where he would follow his interests ...

Aleksei Yeliseyev
Aleksei Stanislavovich Yeliseyev (russian: Алексей Станиславович Елисеев; born 13 July 1934) is a retired Soviet cosmonaut who flew on three missions in the Soyuz programme as a flight engineer: Soyuz 5 , Soyuz 8, and Soyuz 10. He made the world's eighth spacewalk during Soyuz 5 in 1969. Aleksei's father was Lithuanian with the last name Kuraitis, who died in the Soviet's Gulag as an enemy of the people. Aleksei uses his mother's last name "Yeliseyev" so some regard him as also being a Lithuanian cosmonaut. A graduate of the Bauman Higher Technical School (1957) and postgraduate of Moscow Institute of Physics and Technology (1962). Yeliseyev worked as an engineer in Sergey Korolev's design bureau before being selected for cosmonaut training. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Aerial Refueling
Aerial refueling, also referred to as air refueling, in-flight refueling (IFR), air-to-air refueling (AAR), and tanking, is the process of transferring aviation fuel from one aircraft (the tanker) to another (the receiver) while both aircraft are in flight. The two main refueling systems are ''probe-and-drogue'', which is simpler to adapt to existing aircraft, and the ''flying boom'', which offers faster fuel transfer, but requires a dedicated boom operator station. The procedure allows the receiving aircraft to remain airborne longer, extending its range or loiter time. A series of air refuelings can give range limited only by crew fatigue/physical needs and engineering factors such as engine oil consumption. As the receiver aircraft can be topped up with extra fuel in the air, air refueling can allow a takeoff with a greater payload which could be weapons, cargo, or personnel: the maximum takeoff weight is maintained by carrying less fuel and topping up once airborne.

Photovoltaic Module
Photovoltaics (PV) is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry. The photovoltaic effect is commercially used for electricity generation and as photosensors. A photovoltaic system employs solar modules, each comprising a number of solar cells, which generate electrical power. PV installations may be ground-mounted, rooftop-mounted, wall-mounted or floating. The mount may be fixed or use a solar tracker to follow the sun across the sky. Photovoltaic technology helps to mitigate climate change because it emits much less carbon dioxide than fossil fuels. Solar PV has specific advantages as an energy source: once installed, its operation generates no pollution and no greenhouse gas emissions, it shows scalability in respect of power needs and silicon has large availability in the Earth's crust, although other materials required in PV sy ...

Space Suit
A space suit or spacesuit is a garment worn to keep a human alive in the harsh environment of outer space, vacuum and temperature extremes. Space suits are often worn inside spacecraft as a safety precaution in case of loss of cabin pressure, and are necessary for extravehicular activity (EVA), work done outside spacecraft. Space suits have been worn for such work in Earth orbit, on the surface of the Moon, and en route back to Earth from the Moon. Modern space suits augment the basic pressure garment with a complex system of equipment and environmental systems designed to keep the wearer comfortable, and to minimize the effort required to bend the limbs, resisting a soft pressure garment's natural tendency to stiffen against the vacuum. A self-contained oxygen supply and environmental control system is frequently employed to allow complete freedom of movement, independent of the spacecraft. Three types of space suits exist for different purposes: IVA (intravehicular activity ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
