Long March 4B with Shijian-6 Group 5 satellites launches successfully from Jiuquan

The launch took place at 00:11 UTC (08:11 Beijing time) on Friday, December 10, from Site 9401 (SLS-2). Satellite launches from Jiuquan normally take place from this launch pad, using Long March 2, Long March 4, and Long March 11 launch vehicles.

The Long March 4B, which made its first flight in 1999, has flown forty-five missions, with all but one being successful. It is a refinement of the Long March 4 with a restartable third stage, while the Long March 4 series is itself based on older ICBM technology. The Long March 4 series, also known as Chang Zheng 4, uses highly toxic nitrogen tetroxide and UDMH (unsymmetrical dimethylhydrazine) hypergolic propellants like other Long March rockets, as well as older rockets like the American Titan II ICBM used during the Cold War.
