CZ-3
The Long March 3 (), also known as the Changzheng 3, CZ-3 and LM-3, was a Chinese orbital carrier rocket design. They were all launched from Launch Area 3 at the Xichang Satellite Launch Center. It was a three-stage rocket, and was mostly used to place DFH-2-class communications satellites into geosynchronous transfer orbits. It was complemented and later replaced by the more powerful Long March 3A, which has an improved third stage. List of launches Launch failures Dong Fang Hong 2 launch failure On January 29, 1984, a LM-3 rocket failed during launch. The third stage failed 4 s after restart for GTO insertion of the satellite, due to incorrect mixture ratio in the engine gas generator, which caused high temperatures and burned out the turbine casing. However, many planned tests on the experimental communications spacecraft were still carried out in the resulting elliptical orbit.

Long March Rocket
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 350 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 1 (lit. "The East is Red 1"), into low Earth orbit on 24 April 1970, becoming the fifth nation to achieve independent launch capability. Early launch ...

CZ-3B
The Long March 3B (, ''Chang Zheng 3B''), also known as the CZ-3B and LM-3B, is a Chinese orbital launch vehicle. Introduced in 1996, it is launched from Launch Area 2 and 3 at the Xichang Satellite Launch Center in Sichuan. A three-stage rocket with four strap-on liquid rocket boosters, it is currently the second most powerful member of the Long March rocket family after the Long March 5 and the heaviest of the Long March 3 rocket family, and is mainly used to place communications satellites into geosynchronous orbits. An enhanced version, the Long March 3B/E or G2, was introduced in 2007 to increase the rocket's geostationary transfer orbit (GTO) cargo capacity and lift heavier geosynchronous orbit (GEO) communications satellites. The Long March 3B also served as the basis for the medium-capacity Long March 3C, which was first launched in 2008. , the Long March 3B, 3B/E and 3B/G5 have conducted 82 successful launches, plus 2 failures and 2 partial failures, accumulati ...

YF-20
The YF-20 is a Chinese liquid-fuel rocket engine burning N2O4 and UDMH in a gas generator cycle. It is a basic engine which when mounted in a four engine module forms the YF-21. The high altitude variation is known as the YF-22 is normally paired with the YF-23 vernier to form the YF-24 propulsion module for second stages. New versions when used individually for booster applications are called YF-25. Versions The basic engine has been used since the Feng Bao 1 rocket and has been the main propulsion of the Long March 2, Long March 3 and Long March 4 families. * YF-20: Core engine.

Xichang Satellite Launch Center
The Xichang Satellite Launch Center (XSLC), also known as the Xichang Space Center, is a spaceport of China. It is located in Zeyuan Town (), approximately northwest of Xichang, Liangshan Yi Autonomous Prefecture in Sichuan. The facility became operational in 1984 and is used to launch numerous civil, scientific, and military payloads annually. It is notable as the site of Sino-European space cooperation, with the launch of the first of two Double Star scientific satellites in December 2003. Chinese officials have indicated interest in conducting additional international satellite launches from XSLC. In 1996, a fatal accident occurred when the rocket carrying the Intelsat 708 satellite failed on launch from the Xichang Satellite Launch Center. Also, a 2007 test of an anti-satellite missile was launched from the center.

China Academy Of Launch Vehicle Technology
The China Academy of Launch Vehicle Technology (CALT) is a major state-owned civilian and military space launch vehicle manufacturer in China and one of the major launch service providers in the world. CALT is a subsidiary of the larger China Aerospace Science and Technology Corporation (CASC). It was established in 1957 by Dr. Xue-Sen Qian and is headquartered in Fengtai District, Beijing. Its major contribution to China's civilian and military launch capability has been the manufacture of the Long March family of rockets. CALT has 31,600 employees and at least 13 research facilities. The current Chief Designer is Long Lehao (). CALT is also planning two spaceplanes. They would both be single-stage to space sub-orbital rocketplanes. One would be a 10-ton 4-passenger plane that would fly to 100 km at Mach 6. The other would be a 100-ton 20-passenger plane that would fly to 130 km at Mach 8. They would be equipped with liquid methane/liquid oxygen rocket engines. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fengyun
Fēngyún (FY, ) are China's meteorological satellites. Launched since 1988 into polar sun-synchronous and geosynchronous orbit, each three-axis stabilized Fengyun satellite is built by the Shanghai Academy of Spaceflight Technology (SAST) and operated by the China Meteorological Administration ( CMA). To date, China has launched nineteen Fengyun satellites in four classes (FY-1 through FY-4). Fengyun 1 and Fengyun 3 satellites are in polar sun-synchronous orbit while Fengyun 2 and 4 are geosynchronous orbit. On 11 January 2007 China destroyed one of these satellites (FY-1C, COSPAR 1999-025A) in a test of an anti-satellite missile. According to NASA, the intentional destruction of FY-1C created 2,841 high-velocity debris items, a larger amount of dangerous space junk than any other space mission in history. Classes Fengyun 1 The four satellites of the Fengyun 1 (or FY-1) class were China's first meteorological satellites placed in polar, sun-synchronous orbit. In thi ...
