Long March 2 (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). History Long March 2 was the original model in the Long March 2 rocket family, which was derived from China's first ICBM, the DF-5. The development work began in 1970. The first rocket was launched on November 5, 1974, but the launch failed. After the failed first launch of Long March 2, its design was slightly modified and designated as Long March 2A. Long March 2A was successfully launched in 1975. The production of the Long March 2A ended in 1979. Long March 2C and Long March 2D's first launches occurre ...

Pinyin
Hanyu Pinyin, or simply pinyin, officially the Chinese Phonetic Alphabet, is the most common romanization system for Standard Chinese. ''Hanyu'' () literally means 'Han Chinese, Han language'—that is, the Chinese language—while ''pinyin'' literally means 'spelled sounds'. Pinyin is the official romanization system used in China, Singapore, Taiwan, and by the United Nations. Its use has become common when transliterating Standard Chinese mostly regardless of region, though it is less ubiquitous in Taiwan. It is used to teach Standard Chinese, normally written with Chinese characters, to students in mainland China and Singapore. Pinyin is also used by various Chinese input method, input methods on computers and to lexicographic ordering, categorize entries in some Chinese dictionaries. In pinyin, each Chinese syllable is spelled in terms of an optional initial (linguistics), initial and a final (linguistics), final, each of which is represented by one or more letters. Initi ...

The Long March 2F ( ''Changzheng 2F''), also known as the CZ-2F, LM-2F and Shenjian (, "Divine Arrow"), 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 Center. 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". On 29 December 2002, a Long March 2F launched Shenzhou 4 for a final uncrewed test of the Shenzhou spacecraft for the upcoming flight of the first crewed mission. Until then, all missions were uncrewed. On 15 October 2003, a Long March 2F launched Shenzhou 5, China's maiden crewed mission and achieved its first huma ...

Shenzhou 1
Shenzhou 1 () was the first uncrewed launch of the Shenzhou spacecraft, launched on 19 November, 1999. The spacecraft used was not equipped with a life support system, but did come with an emergency escape system. After orbiting the Earth 14 times, the command for retrofire was sent by the '' Yuan Wang 3'' tracking ship off the coast of Namibia at 18:49 UTC. After a successful reentry it landed about east of its launch pad and north-west of Wuhai, Inner Mongolia. The first Shenzhou spacecraft was different from those later used. Instead of featuring unfolding solar panels, ''Shenzhou 1'' was equipped with fixed solar cells. During this first flight there were also no orbit changes. According to Qi Faren, the chief designer of the spacecraft, only 8 of the 13 sub-systems on board the spacecraft were operational. Shenzhou 1 was designed primarily to test the Long March 2F rocket. The only systems and capabilities tested on the spacecraft were the separation of the modules, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
