Jiuquan Satellite Launch Center (JSLC; Chinese: 酒泉卫星发射中心; pinyin: Jiǔquán Wèixīng Fāshè Zhōngxīn also known as Shuangchengzi Missile Test Center; Launch Complex B2; formally Northwest Comprehensive Missile Testing Facility (西北综合导弹试验基地); Base 20; 63600 Unit) is a Chinese space vehicle launch facility (spaceport) located in the Gobi desert, Inner Mongolia. It is part of the Dongfeng Aerospace City (Base 10). 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.
It was founded in 1958, the first of China's four spaceports. More Chinese launches have occurred at Jiuquan than anywhere else. As with all Chinese launch facilities it is remote and generally closed to foreigners.
The Satellite Launch Center is a part of Dongfeng space city (东风航天城), also known as Base 10 (十号基地) or Dongfeng base (东风基地), which also includes PLAAF test flight facilities, a space museum and a martyr's cemetery (东风烈士陵园).
JSLC is usually used to launch vehicles into lower and medium orbits with large orbital inclination angles, as well as testing medium to long-range missiles. Its facilities are state of the art and provide support to every phase of a satellite launch campaign. The site includes the Technical Center, the Launch Complex, the Launch Control Center, the Mission Command and Control Center and various other logistical support systems.
The center covers 2800 km² and may have housing for as many as 20,000 people. The facilities and launch support equipment were likely modelled on Soviet counterparts and the Soviet Union has likely provided technical support to Jiuquan.
The launch center has been the focus of many of China's ventures into space, including their first satellite Dong Fang Hong 1 in 1970, and their first crewed space mission Shenzhou 5 on 15 October 2003.
Shenzhou 7, the third crewed spaceflight mission of the Chinese space program, was launched from JSLC on 25 September 2008 by a Long March 2F (CZ-2F) rocket. The mission, which included an extra-vehicular activity (EVA) carried out by crewmembers Zhai Zhigang and Liu Boming, marked the commencement of the second phase of the Chinese government's Project 921.
China's fourth crewed spaceflight, Shenzhou 9, launched from JSLC on 16 June 2012 at 18:37 local time (10:37 UTC). The 13-day mission included China's first female astronaut and docked with the country's Tiangong-1 space station module on Monday, 18 June 2012.
In August 2018, Chinese private rocket manufacturing startups i-Space and OneSpace launched sub-orbital rockets from the center. On July 25, 2019, the first Chinese private orbital launch took place from Jiuquan as I-Space launched their Hyberbola-1 rocket.
The launch pads at Launch Area 2 are located at approximately 41.308833° north, 100.316512° east (north pad) and 41.306143° north, 100.313229° east (south pad).
Launch Area 3 is approximately 2.7 km south of Launch Area 2. The launch pads are located at approximately 41.283190° north, 100.304706° east (north pad) and 41.280457° north, 100.304582° east (south pad).
- Launch Area 4 (South Launch Site), 2 launch pads, only active complex:
Launch Area 4 is approximately 37.9 km south of Launch Area 3. The launch pads are located at approximately 40.960671° north, 100.298186° east (north pad) and 40.957893° north, 100.290944° east (south pad).
