Long March rocket.
|
The Long March rocket family, China's indigenously developed launch vehicle
group,
includes 12 different versions capable of placing satellites into low-earth
(LEO), geo-stationary
(GEO), and
sun-synchronous orbits.[1] China continues to advance its launch vehicle
technology and used the upgraded Long March-2F rocket with improved guidance and control systems, engines, and computer
systems to launch its first man into space in October 2003.[2] China is
also experimenting with heavy-lift space launch
vehicles and plans to be able to launch 25 tons into LEO and 14 tons
into GEO.[3] This
Long March-5 rocket will triple the GEO payload capability of the current
Long
March-2F rocket.[4] In
September 2003 China successfully tested its first four-stage solid-fuel launch
vehicle, Kaituozhe-1 (KT-1), capable of placing microsatellites in orbit.[3,5] China has
also made strides in its reusable vehicle technology for its manned space
program, “Project 921,” initiated in 1992.[2] China
conducted successfully its first manned mission on October 15, 2003 using the Shenzhou-V
spacecraft, which is similar to the Russian Soyuz spacecraft.[2,6] Four
successful unmanned Shenzhou launches had already taken place.[6] The
launch of the Shenzhou-6 on October 12, 2005, was designed to place two
astronauts (taikonauts) into orbit for several days, a significant
improvement upon the single person placed in orbit for 21 hours in the first manned
mission.[7]
Active Chinese Space Launch Facilities.

Chinese launches take place at one of three
sites: Jiuquan Satellite Launch Center, Taiyuan Satellite Launch Center, or Xichang
Satellite Launch Center. Launches at Jiuquan, China's oldest space launch
base, consist primarily of scientific, technical, and experimental satellites in
lower- and middle-earth orbits.[8] Located in Gansu province in northwest
China, Jiuquan was also the launch site of China's first manned space mission.[8,9] The Taiyuan Satellite Launch
Center, found in Kelan County in Shanxi Province, is considered to be an ideal
site for launching sun-synchronous satellites due to its dry weather
conditions.[8] The Xichang Satellite Launch Center, situated in the Liangshan Yi
Autonomous Prefecture in Sichuan province, handles launches of geostationary
satellites.[9] China has
also
decided upon a fourth launch site on Hainan island, which will
be more efficient in terms of fuel and payload capacity for a launch into
GEO.[4] It is expected to be operational in time for the first test flight of the Long March-5 heavy-lift rocket in 2008.[4]
China maintains an advanced telemetry, tracking, and command network (TT&C).[10] It currently includes: eight domestic, ground-tracking stations;
two foreign-based ground-tracking stations in Kiribati (located in the South
Pacific Ocean) and Namibia (located in southwestern Africa); four Yuanwang-class tracking ships; and two control facilities, the Xian Satellite
Control Center in central China and the Beijing Spaceflight Command and Control
Center.[10,11,12,13]
China completed upgrades to its TT&C network in 2000, including the addition
of an S-band tracking capability, a frequency used for geo-stationary satellite
tracking.[10,11] Additionally, in
March 2005 China established the Space Target and Debris Observation and
Research Center to aid in the prevention of debris strikes against satellites and manned spacecraft.[14]
