Long March (rocket Family)
The Long March rockets are a family of expendable launch system rockets operated by the China Aerospace Science and Technology Corporation. The rockets are named after the Chinese Red Army's 1934–35 Long March military retreat during the Chinese Civil War. The Long March series has performed more than 500 launches, including missions to low Earth orbit, Sun-synchronous orbit, geostationary transfer orbit, and Earth-Moon transfer orbit. The new-generation carrier rockets, Long March 5, Long March 6, Long March 7, Long March 11, and Long March 8, have made their maiden flights. Among them, the Long March 5 has a low-Earth orbit carrying capacity of 25,000 kilograms, and a geosynchronous transfer orbit carrying capacity of 14,000 kilograms. History China used the Long March 1 rocket to launch its first satellite, Dong Fang Hong I, Dong Fang Hong 1 (lit. "The East is Red 1"), into low Earth orbit on 24 April 1970, becoming the fifth nation to achieve independent launch capabil ...

AsiaSat 1
AsiaSat 1 was a Hong Kong communications satellite, which was owned, and was operated, by the Hong Kong–based Asia Satellite Telecommunications Company. It was originally launched in February 1984 as Westar 6, but following a booster motor failure it was retrieved and returned to Earth in November of that year by Space Shuttle mission STS-51-A. After being sold to AsiaSat and refurbished, it was relaunched in April 1990, and positioned in geostationary orbit at a longitude of 100.5° East. It spent its operational life at 100.5° East, from where it was used to provide fixed satellite services, including broadcasting, audio and data transmission, to Asia and the Pacific Ocean. Westar 6 As Westar 6, the satellite was built by Hughes Space and Communications. It was based on the HS-376 satellite bus. At launch it had a mass of , and a design life of thirteen years. It carried twenty four C-band transponders. After launch from the Space Shuttle as part of mission STS-4 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jiuquan Satellite Launch Center
Jiuquan Satellite Launch Center (JSLC; also known as Shuangchengzi Missile Test Center; Launch Complex B2; formally Northwest Comprehensive Missile Testing Facility (); Base 20; 63600 Unit) is a Chinese space vehicle launch facility ( spaceport), a corps grade subordinate unit of the PLA Aerospace Force. It is located between the Ejin Banner, Alxa League, Inner Mongolia and Hangtian Town, Jinta County, Jiuquan Prefecture, Gansu Province. It is part of the Dongfeng Aerospace City (Base 10).

Long March 2C
The Long March 2C (LM-2C), also known as the Chang Zheng 2C (CZ-2C), is a Chinese orbital launch vehicle, part of the Long March 2 rocket family. Developed and manufactured by the China Academy of Launch Vehicle Technology (CALT), the Long March 2C made its first launch on 9 September 1982. It is a two-stage launch vehicle with storable propellants, consisting of Nitrogen Tetroxide and Unsymmetrical Dimethylhydrazine. The launch vehicle was derived from the DF-5 ICBM. Several variants of this launch vehicle have been built, all using an optional third solid motor stage: * 2C/SD: Commercial satellite launcher with a multi-satellite smart dispenser allowing delivery of two satellites simultaneously * 2C/SM: Version for delivery of small satellites to high orbits * 2C/SMA: Improved version of the 2C/SM According to the website ''Gunter's Space Page'', in addition to the launches listed in the following table, there may have been six additional CZ-2C launches during 2014 and 2 ...

Sun Synchronous Orbit
A Sun-synchronous orbit (SSO), also called a heliosynchronous orbit, is a nearly polar orbit around a planet, in which the satellite passes over any given point of the planet's surface at the same local mean solar time. More technically, it is an orbit arranged so that it precesses through one complete revolution each year, so it always maintains the same relationship with the Sun. Applications A Sun-synchronous orbit is useful for imaging, reconnaissance, and weather satellites, because every time that the satellite is overhead, the surface illumination angle on the planet underneath it is nearly the same. This consistent lighting is a useful characteristic for satellites that image the Earth's surface in visible or infrared wavelengths, such as weather and spy satellites, and for other remote-sensing satellites, such as those carrying ocean and atmospheric remote-sensing instruments that require sunlight. For example, a satellite in Sun-synchronous orbit might ascend acros ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taiyuan Launch Area 7
Taiyuan; Mandarin pronunciation: ( Taiyuan Jin: /tʰai˦˥ ye˩˩/) is the capital of Shanxi, China. Taiyuan is the political, economic, cultural and international exchange center of Shanxi Province. It is an industrial base focusing on energy and heavy chemicals. Throughout its long history, Taiyuan was the capital or provisional capital of many dynasties in China, hence the name ( zh, s=龙城, p=Dragon City, labels=no). As of 2021, the city governs 6 districts, 3 counties, and hosts a county-level city with a total area of 6,988 square kilometers and a permanent population of 5,390,957. Taiyuan is located roughly in the centre of Shanxi, with the Fen River flowing through the central city. Etymology and names The two Chinese characters of the city's name are (, "great") and (, "plain"), referring to the location where the Fen River leaves the mountains and enters a relatively flat plain. Throughout its long history, the city had various names, including () (from wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taiyuan Satellite Launch Center
The Taiyuan Satellite Launch Center (TSLC) also known as ''Base 25'' (), is a People's Republic of China space and defense launch facility (spaceport). It is situated in Kelan County, Xinzhou, Shanxi Province and is the second of four launch sites having been founded in March 1966 and coming into full operation in 1968. The facility was built as part of China's Third Front campaign to develop basic industry and national security in China's rugged interior in case of invasion by the Soviet Union or the United States. Taiyuan sits at an altitude of 1500 meters and its dry climate makes it an ideal launch site. The site is primarily used to launch meteorological satellites, Earth resource satellites and scientific satellites on Long March launch vehicles into Sun-synchronous orbits. TSLC is also a major launch site for intercontinental ballistic missiles and overland submarine-launched ballistic missile (SLBM) tests. The site has a sophisticated Technical Center and Missio ...

Long March 4A
The Long March 4A (), also known as the Changzheng 4A, CZ-4A and LM-4A, sometimes misidentified as the Long March 4 due to the lack of any such designated rocket, was a Chinese orbital carrier rocket. It was launched from Launch Area 7 at the Taiyuan Satellite Launch Center. It was a three-stage rocket, used for two launches in 1988 and 1990. On its maiden flight, on 6 September 1988, it placed the FY-1A weather satellite into orbit. On its second, and final, flight it launched another weather satellite, FY-1B. A month after the launch of FY-1B, the third-stage of the CZ-4A launch vehicle exploded in a 895 x 880 km orbit, creating more than 100 pieces of space debris. This incident led to a redesign of the rocket to include a residual propellant venting system. A venting system was not included in the 4A because of the concern that it would damage the satellite. It was replaced by a derivative, the Long March 4B The Long March 4B (), also known as the Chang Zheng 4B, CZ-4B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Low Earth Orbit
A low Earth orbit (LEO) is an geocentric orbit, orbit around Earth with a orbital period, period of 128 minutes or less (making at least 11.25 orbits per day) and an orbital eccentricity, eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, peaking in number at an altitude around , while the farthest in LEO, before medium Earth orbit (MEO), have an altitude of 2,000 km, about one-third of the Earth radius, radius of Earth and near the beginning of the Van Allen radiation belt#Inner belt, inner Van Allen radiation belt. The term ''LEO region'' is used for the area of space below an altitude of (about one-third of Earth's radius). Objects in orbits that pass through this zone, even if they have an apogee further out or are sub-orbital spaceflight, sub-orbital, are carefully tracked since they present a collision risk to the many LEO satellites. No human spaceflights other than the lunar missions of the Apollo program (1968-1972) have gone beyond L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
