Meanwhile, the construction demand of the launch site of the commercial space is analyzed. A conception building a LOX-methane launch site in Jiuquan Satellite Launch Center is proposed. The launch site can meet the demand of dynamical system test run, test and launch of LOX-methane launch vehicle. A conceptual design program of the LOX-methane launch site is brought forward. The program includes assorted launch vehicles, general technical indexes, basic test-launch mode, site selection, general safety, and major constructions. The demonstration shows, the conceptual design program can meet the need of launch mission, and the construction scale is moderate. The conceptual design program can fulfill the demand of the programed LOX-methane launch vehicles in China. Using the launch site, a ZQ-2 launch vehicle is flying to the space in December 2023.
