The Long March 2A, also known as the Chang Zheng 2A, CZ-2A and LM-2A, was a Chinese orbital carrier rocket.

It was launched from Launch Area 2B at the Jiuquan Satellite Launch Centre. It was a 2-stage rocket, and flew 4 times. On its first flight on 5 November 1974, a cable connecting the pitch rate control gyroscope to the guidance system became disconnected, resulting in a loss of control and launch failure.

The rocket was subsequently replaced by the more capable Long March 2C.

The payloads for the Long March 2A were FSW-0 reconnaissance satellites.

A Long March rocket is any rocket in a family of expendable launch systems operated by the People's Republic of China. Development and design falls under the auspices of the China Academy of Launch Vehicle Technology. In English, the rockets are abbreviated as LM- for export and CZ- within China, as "Chang Zheng" means "Long March" in Chinese pinyin. The rockets are named after the Long March of Chinese communist history.

The Long March 2F, also known as the CZ-2F, LM-2F and Shenjian, is a Chinese orbital carrier rocket, part of the Long March 2 rocket family. Designed to launch crewed Shenzhou spacecraft, the Long March 2F is a human-rated two-stage version of the Long March 2E rocket, which in turn was based on the Long March 2C launch vehicle. It is launched from complex SLS at the Jiuquan Satellite Launch Centre. The Long March 2F made its maiden flight on 19 November 1999, with the Shenzhou 1 spacecraft. After the flight of Shenzhou 3, CPC General Secretary and President Jiang Zemin named the rocket 'Shenjian' meaning 'Divine Arrow'.

Jiuquan Satellite Launch Center spaceport in China

Jiuquan Satellite Launch Center is a Chinese space vehicle launch facility (spaceport) located in the Gobi Desert, Inner Mongolia. It is part of the Dongfeng Aerospace City. Although the facility is geographically located within Ejin Banner of Inner Mongolia's Alxa League, it is named after the nearest city, Jiuquan in Gansu Province.

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 3-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.

The Long March 3A, also known as the Chang Zheng 3A, CZ-3A and LM-3A, is a Chinese orbital carrier rocket design. It is a 3-stage rocket, and is usually used to place communications satellites and Beidou navigation satellites into geosynchronous transfer orbits.

Taiyuan Satellite Launch Center launch site in China

The Taiyuan Satellite Launch Center (TSLC) also known as Base 25, is a People's Republic of China space and defence 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. Taiyuan sits at an altitude of 1500 meters and its dry climate makes it an ideal launch site. Confusingly, U.S. intelligence designates TSLC the "Wuzhai Missile and Space Test Centre", despite the fact that it is outside the borders of Wuzhai County. 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 Long March 1 (长征一号), also known as the Changzheng-1 (CZ-1), was the first member of China's Long March rocket family.

Long March 2 rocket family or Chang Zheng 2 rocket family as in Chinese pinyin is an expendable launch system operated by the People's Republic of China. The rockets use the abbreviations LM-2 family for export, and CZ-2 family within China, as "Chang Zheng" means "Long March" in Chinese pinyin. They are part of the larger Long March rocket family. Development and design falls mostly under the auspices of the China Academy of Launch Vehicle Technology (CALT).

Long March 5 Chinese next-generation heavy lift launch system

Long March 5 is a Chinese heavy lift launch system developed by the China Academy of Launch Vehicle Technology (CALT). It is the first Chinese launch vehicle designed from the ground up to focus on non-hypergolic liquid rocket propellants. There are currently two CZ-5 variants: CZ-5 and CZ-5B. The maximum payload capacities of the base variant is ~25,000 kilograms (55,000 lb) to LEO and ~14,000 kilograms (31,000 lb) to GTO. The Long March 5 roughly matches the capabilities of American EELV heavy-class vehicles such as the Delta IV Heavy. It is currently the most powerful member of the Long March rocket family.

Intelsat 708 United States failed satellite launch

Intelsat 708 was a telecommunications satellite built by the American company Space Systems/Loral for Intelsat. It was destroyed on 15 February 1996 when the Long March 3B rocket failed while being launched from the Xichang Satellite Launch Center in China. The rocket veered off course immediately after liftoff and struck a nearby village, killing at least six people.

Long March 2C (LM-2C), or Chang Zheng 2C (CZ-2C) as in Chinese pinyin is a member of the Long March 2 rocket family, an expendable launch system operated by the People's Republic of China.
