Jiuquan Satellite Launch Center

Jiuquan Satellite Launch Center (JSLC; Template:Zh), also known as the Shuang Cheng Tzu Missile Test Center, Launch Complex B2, the Northwest Comprehensive Missile Testing Facility (), Base 20, or Unit 63600, is a Chinese spaceport and a corps-grade unit subordinate to the People's Liberation Army Aerospace Force. It is located between Ejin Banner, Alxa League, Inner Mongolia, and Hangtian Town, Jinta County, Jiuquan Prefecture, Gansu Province. The center forms part of Dongfeng Aerospace City (Base 10). Although most of the facility lies within Jinta County, the spaceport is named after Jiuquan. The launch center spans both sides of the Ruo Shui river.

History

Founded in 1958, JSLC is the oldest of China’s four spaceports. Like most Chinese launch facilities, it is located in a remote area and is generally closed to foreign visitors.

The launch center is part of Dongfeng Space City (), also known as Base 10 () or the Dongfeng base (). The broader Dongfeng site includes test-flight facilities for the People's Liberation Army Air Force (PLAAF), a space museum, and a martyrs’ cemetery ().Template:Better source needed

JSLC is used for launching spacecraft into low- and medium-Earth orbits with high inclination, as well as for testing medium- and long-range missiles. Its facilities include the technical center, launch complexes, launch control center, mission command center, and associated logistical systems.

The center covers about 2,800 km² and reportedly houses up to 20,000 personnel. Many of its systems and equipment were likely modelled on Soviet designs, and the Soviet Union probably provided early technical assistance.

JSLC was expanded during China’s Third Front campaign to develop defense-related industry in inland regions in anticipation of potential conflict with the Soviet Union or the United States.Template:Rp

The site has supported many major Chinese space milestones, including the launch of China’s first satellite Dong Fang Hong I in 1970,Template:Rp and the first crewed space mission Shenzhou 5 in 2003. As of 2021, all Chinese crewed launches—including missions to the Tiangong space station—have originated from Jiuquan.

In August 2016, China launched the first quantum-communication satellite, Quantum Experiments at Space Scale, from JSLC.

In August 2018, Chinese commercial rocket companies i-Space and OneSpace conducted sub-orbital launches from the center. On 25 July 2019, I-Space carried out the first successful Chinese private orbital launch from Jiuquan using the Hyperbola-1 rocket.

Launch pads

The launch site includes two launch complexes, each with multiple pads.

North Launch Complex

The North Launch Complex contains two inactive launch areas.

• Launch Area 2: used for orbital launches and ballistic-missile tests.
  • LA-2A: used for DF-3 and DF-5 ballistic-missile launches and for the earliest Chinese orbital missions using the CZ-1 (last orbital launch in 1971). ()
  • LA-2B: used for CZ-2A, CZ-2C, CZ-2D, and FB-1 launches (last used in 1996). ()

• Launch Area 3: located about south of LA-2, used for DF-1, DF-2, and R-2 missile launches.

  • South pad ()

South Launch Complex

The South Launch Complex is active and supports launches of CASC's Long March vehicles as well as commercial rockets.

• Launch Area 4: about south of LA-3.
  • SLS-1 (LS-43/91): active since 1999, used for crew-rated Long March 2F missions and served by a nearby Vertical Assembly Facility. ()
  • SLS-2 (LS-43/94): active since 2003, used for Long March 2C, Long March 2D, Long March 4B, and Long March 4C launches. ()

• Commercial launch pads (various locations south and east of LA-4):
  • LS-95: two pads used for Long March 11, Kuaizhou, Jielong 1, OS-M1, Hyperbola-1, and Ceres-1 launches.
    • Pad A ()
    • Pad B ()
  • LS-96: operated by LandSpace for the Zhuque-2 launcher. ()
  • LS-120: operated by Space Pioneer for the Tianlong-2 launcher. ()
  • LS-130: operated by CAS Space for the Kinetica 1 launcher. ()
