Deorbit Of Mir
The Russian space station ''Mir'' ended its mission on 23 March 2001, when it was brought out of its orbit, Atmospheric entry, entered the atmosphere and was destroyed. Major components ranged from about 5 to 15 years in age, and included the Mir Core Module, Kvant-1, Kvant-2, Kristall, Spektr, Priroda, and Mir Docking Module, Docking Module. Although Russia was optimistic about ''Mir'' future, the country's commitments to the International Space Station programme left no funding to support ''Mir''. The deorbit was carried out in three stages. The first stage was waiting for atmospheric Drag (physics), drag to Orbital decay, decay the orbit to an average of . This began with the docking of Progress M1-5. The second stage was the transfer of the station into a orbit. This was achieved with two burns of the Progress M1-5's control engines at 00:32 UTC and 02:01 UTC on 23 March 2001. After a two-orbit pause, the third and final stage of ''Mirs deorbit began with the firing of Pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shenzhou Spacecraft
Shenzhou (, ; see ) is a Chinese spacecraft developed for the nation's crewed space program. Its design was based on Russia's Soyuz, but larger and modernized. Like Soyuz, Shenzhou is a single-use vehicle composed of three modules; a descent module which houses the crew during launch and reentry, an orbital module which provides additional living space and storage during orbit, but is jettisoned before reentry, and a service module responsible for propulsion and power, also discarded before reentry. For added safety and aerodynamics, the spacecraft is encased within a fairing and fitted with a launch escape system during liftoff. Its maiden uncrewed flight, Shenzhou 1, was on 19 November 1999, with the first crewed mission, Shenzhou 5, taking flight on 15 October 2003. It is slated for replacement by the next-generation Mengzhou, currently in development, with a two module configuration. Etymology The literal meaning of the native name ( p: Shénzhōu; ) is "the Divine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atmospheric Re-entry
Atmospheric entry (sometimes listed as Vimpact or Ventry) is the movement of an object from outer space into and through the gases of an atmosphere of a planet, dwarf planet, or natural satellite. Atmospheric entry may be ''uncontrolled entry,'' as in the entry of astronomical objects, space debris, or bolides. It may be ''controlled entry'' (or ''reentry'') of a spacecraft that can be navigated or follow a predetermined course. Methods for controlled atmospheric ''entry, descent, and landing'' of spacecraft are collectively termed as ''EDL''. Objects entering an atmosphere experience atmospheric drag, which puts mechanical stress on the object, and aerodynamic heating—caused mostly by compression of the air in front of the object, but also by drag. These forces can cause loss of mass (ablation) or even complete disintegration of smaller objects, and objects with lower compressive strength can explode. Objects have reentered with speeds ranging from 7.8 km/s for l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russian Federal Space Agency
The State Corporation for Space Activities "Roscosmos", commonly known simply as Roscosmos (), is a state corporation of the Russian Federation responsible for space flights, cosmonautics programs, and aerospace research. Originating from the Soviet space program founded in the 1950s, Roscosmos emerged following the dissolution of the Soviet Union in 1991. It initially began as the Russian Space Agency,, ''Rossiyskoye kosmicheskoye agentstvo'', or RKA (). which was established on 25 February 1992 and restructured in 1999 and 2004 as the Russian Aviation and Space Agency, ''Rossiyskoye aviatsionno-kosmicheskoye agentstvo'', commonly known as (), established on 25 May 1999. and the Federal Space Agency (Roscosmos), (Роскосмос), ''Federalnoye kosmicheskoye agentstvo (Roskosmos)''. respectively. In 2015, the Federal Space Agency (Roscosmos) was merged with the United Rocket and Space Corporation, a government corporation, to re-nationalize the space industr ...

Gagarin's Start
Gagarin's Start (, ''Gagarinskiy start''), also known as Baikonur Site 1 or Site 1/5 was a launch site at the Baikonur Cosmodrome in Kazakhstan that was used by the Soviet space program and Roscosmos. History 20th century The launchpad for the world's first human spaceflight made by Yuri Gagarin on Vostok 1 in 1961, the site was referred to as Site No.1 (, ''Ploshchadka No. 1'') as the first one of its kind. It is also sometimes referred to as NIIP-5 LC1, Baikonur LC1, LC-1/5, LC-1, Pad 1/5 or GIK-5 LC1. At Baikonur, site numbers refer to facilities. Site 0 was the construction headquarters and residential area and, as the first major project, this launch pad was named Site 1. Its processing facilities were called Site 2 and its oxygen/nitrogen plant was Site 3. The facility was later designated as Pad No. 5 for the R-7 programme. The numbering of the sites reflected Baikonur's role as a secondary ICBM base, with the primary being the Plesetsk Cosmodrome, which featured ...

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 launched from Baikonur. Situated in the Kazakh Steppe, some above sea level, it is to the east of the Aral Sea and north of the Syr Darya. It is close to Töretam, a station on the Trans-Aral Railway. Russia, as the official successor state to the Soviet Union, has retained control over the facility since 1991; it originally assumed this role through the post-Soviet Commonwealth of Independent States (CIS), but ratified an agreement with Kazakhstan in 2005 that allowed it to lease the spaceport until 2050. It is jointly managed by Roscosmos and the Russian Aerospace Forces. In 1955, the Ministry of Defense (Soviet Union), Soviet Ministry of Defense issued a decree and founded the Baikonur Cosmodrome. It was originally built as the chief ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soyuz-U
Soyuz-U ( GRAU index: 11A511U) was a Soviet and later Russian expendable medium-lift launch vehicle designed by the TsSKB design bureau and constructed at the Progress factory in Samara, Russia. The ''U'' designation stands for ''unified'', as the launch vehicle was the replacement for both the Voskhod rocket and the original Soyuz rocket. The Soyuz-U is part of the R-7 rocket family, which evolved from the R-7 Semyorka, an intercontinental ballistic missile. The first Soyuz-U flight took place on 18 May 1973, carrying as its payload Kosmos 559, a Zenit military surveillance satellite. The final flight of a Soyuz-U rocket took place on 22 February 2017, carrying Progress MS-05 to the International Space Station. Soyuz-U was in use continuously for almost 44 years. Production of R-7 derived launch vehicles peaked in the late 1970s-early 1980s at 55–60 a year. Soyuz-U held the world record of highest launch rate in a year in 1979 with 47 flights until this was bea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Communications Satellite
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a Transponder (satellite communications), transponder; it creates a communication channel between a source transmitter and a Radio receiver, receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. Many communications satellites are in geostationary orbit above the equator, so that the satellite appears stationary at the same point in the sky; therefore the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track the satellite. Others form satellite constellations in low Earth orbit, where antennas on the ground have to follow the position of the satellites and switch between satellites frequently. The radio waves used for telecommunications links travel by Line-of-sight propagation, line of sight and so are obstructe ...

Geosynchronous Orbit
A geosynchronous orbit (sometimes abbreviated GSO) is an Earth-centered orbit with an orbital period that matches Earth's rotation on its axis, 23 hours, 56 minutes, and 4 seconds (one sidereal day). The synchronization of rotation and orbital period means that, for an observer on Earth's surface, an object in geosynchronous orbit returns to exactly the same position in the sky after a period of one sidereal day. Over the course of a day, the object's position in the sky may remain still or trace out a path, typically in a figure-8 form, whose precise characteristics depend on the orbit's inclination and eccentricity. A circular geosynchronous orbit has a constant altitude of . A special case of geosynchronous orbit is the geostationary orbit (often abbreviated ''GEO''), which is a circular geosynchronous orbit in Earth's equatorial plane with both inclination and eccentricity equal to 0. A satellite in a geostationary orbit remains in the same position in the sky to observers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Türksat (satellite)
Türksat is the name of a series of Turkish communications satellites operated or projected by the state-owned Türksat A.Ş. Satellite telecommunication is provided by the Gölbaşı Ground Station in Ankara, Turkey. Missions Satellites Türksat 1A Türksat 1A was the first attempt of the project and launched by Ariane 4 from Centre Spatial Guyanais in Kourou, French Guiana on 24 January 1994. Due to the failure of the launcher, the satellite exploded in the atmosphere before reaching its orbit. Türksat 1B After the loss of Turksat 1A, Türksat 1B was successfully located at 42°E orbit on 11 August 1994. After the orbital tests, Turksat 1B was put into service on 10 October 1994. Turksat 1B has three different coverage areas, Turkey, Central Europe and Central Asia. The satellite carries 16 transponders, 10 of 36 MHz, 6 of 72 MHz operating in Ku-band (11–14 GHz). There are 4 transponder switching capability between Turkey and Central Europe, and 3 betwe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
