BEIJING, Dec 4 (Reuters) - Beijing-based LandSpace Technology, one of China's private space companies, is preparing to launch a satellite payload to orbit in the first commercial test of its rocket powered by liquid fuel using methane and oxygen. The company did not specify a launch window for the rocket, which will blast off from Jiuquan Satellite Launch Center in Inner Mongolia. The company had fundraising rounds of undisclosed sizes since, Chinese company record tracking database Tianyancha showed. LandSpace rival OrienSpace, founded in 2020, said it plans to launch its first rocket, Gravity-1, based on solid fuel, in December.
