Jiuquan Launch Center, LA-4, SLS-2

Jiuquan Satellite Launch Center (JSLC; Chinese: 酒泉卫星发射中心) 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. The launch center straddles both sides of the Ruo Shui river.

Launch Area 4 (LA-4), also known as the South Launch Site or SLS, and LC-43, is the only active Long March launch complex at the Jiuquan Satellite Launch Center. It consists of two launch pads; SLS-1 / 921 (LC-43/91)[3] and SLS-2 / 603 (LC-43/94). SLS-1 has been the launch site for all missions conducted as part of the Shenzhou programme, including the first Chinese crewed spaceflight, Shenzhou 5. Since it was activated in 1999; Long March 2C, Long March 2D, Long March 2F, Long March 4C and Long March 11 rockets have launched from LA-4.

SLS-2 became operational in 2003, and has since been used for most unmanned launches from Jiuquan. As of November 2021, 95 launches have been made from the complex. The most recent launch from the site was from SLS-2 on 3 November 2021, with a Long March 2C, carrying the Yaogan 32-02 satellite.
