BEIJING, March 16 (Xinhua) -- A Chinese high-thrust oxyhydrogen rocket engine has completed a 520-second test in preparation for the upcoming launches of space station lab modules, its maker said on Wednesday.
Developed by the China Aerospace Science and Technology Corporation, the engine is designed for the core stage of the Long March-5 carrier rocket series, which will be used to launch two lab modules of China's orbiting Tiangong space station this year.
The long-range test, lasting 520 seconds, has verified the reliability of the engine, and there will be more than 20 experimental tasks that the rocket engine will undergo to further test its performance, the company disclosed.
China plans to have six more missions, including the launch of the Wentian and Mengtian lab modules, two cargo spacecraft and two crewed spaceships, in 2022 to complete the construction of the space station. ■
