Soyuz 7K-OK(A) Drawing
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 with the International Space Station (ISS). , the 7K-OK was responsible 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. Additional 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 Union of Soviet Socialist Republics. (USSR), commonly known as the Soviet Union, was a List of former transcontinental countries#Since 1700, transcontinental country that spanned much of Eurasia from 1922 until Dissolution of the Soviet Union, it dissolved in 1991. During its existence, it was the list of countries and dependencies by area, largest country by area, extending across Time in Russia, eleven time zones and sharing Geography of the Soviet Union#Borders and neighbors, borders with twelve countries, and the List of countries and dependencies by population, third-most populous country. An overall successor to the Russian Empire, it was nominally organized as a federal union of Republics of the Soviet Union, national republics, the largest and most populous of which was the Russian SFSR. In practice, Government of the Soviet Union, its government and Economy of the Soviet Union, economy were Soviet-type economic planning, highly centralized. As a one-party state go ...

Soyuz 11
Soyuz 11 () was the only crewed mission to board the world's first space station, Salyut 1. 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-person 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, Valery 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 Dobrovolsky and Patsayev, this was to be their first space mission. After the failure of Salyut 2 to orbit, Kubasov and Leonov were reassigned to Soyuz 19 for the Apollo-Soyuz Test Project ...

Kosmos 212
Kosmos 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 The Baikonur Cosmodrome is a spaceport operated by Russia within Kazakhstan. Located in the Kazakh city of Baikonur, it is the largest operational space launch facility in terms of area. All Russian Human spaceflight, crewed spaceflights are l ... and the planned mission could be carried out.

Kosmos 140
Kosmos 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 repair. LC-31 was also ...

SSVP Docking System
Sistema Stykovki i Vnutrennego Perekhoda, SSVP (, ''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 of large modules, such as the ones that would be used to construct ''Mir''. They ...

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. He 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 i ...

Aleksei Yeliseyev
Aleksei Stanislavovich Yeliseyev (; 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 spacecraft, space vehicles. This connection can be temporary, or wiktionary:semipermanent, 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 orbital station-keeping, 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 6A, Gemini 6 to rendezvous and manually dock under the command of Wally ...

Aerial Refueling
Aerial refueling ( en-us), or aerial refuelling ( en-gb), 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. Because the receiver aircraft is topped-off 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 ...

Igla (spacecraft Docking System)
The Igla (, "Needle") docking system was a Soviet radio telemetry system for automated docking of Soyuz (spacecraft), Soyuz spacecraft. The first prototypes were made in late 1965. On 30 October 1967, the first automated docking of Soyuz uncrewed spacecraft took place. Problems * The Soyuz 15 mission was aborted when the system failed to dock to the Salyut#Salyut 3, Salyut 3, on 26 August 1974. There was no manual backup system. * Salyut#Salyut5, Salyut 5, launched on June 22, 1976, was equipped with an improved radio system. On July 6, 1976, Soyuz 21 had problems undocking automatically, but was able to undock manually. Soyuz 23 failed to dock, ran out of fuel to manual dock, and returned to Earth. *The Igla docking system suffered an engine failure on Soyuz 33 on 10 April, 1979. After consideration by ground crews, the mission was aborted by firing the back up engines and initiating a ballistic reentry. Kurs In 1986 Igla was succeeded by the Kurs (docking system), Kurs docking s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 does not generate any pollution or any 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 ...

Space Suit
A space suit (or spacesuit) is an environmental suit used for protection from the harsh environment of outer space, mainly from its vacuum as a highly specialized pressure suit, but also its temperature extremes, as well as radiation and micrometeoroids. Basic space suits are worn as a safety precaution inside spacecrafts in case of loss of cabin pressure. For extravehicular activity (EVA) more complex space suits are worn, featuring a portable life support system. Pressure suits are in general needed at low pressure environments above the Armstrong limit, at around above Earth. Space suits augment pressure suits with 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 ...
