emirates7 - A spacecraft testing facility in northwest China's Shaanxi Province has successfully completed the test firing of a newly-constructed high-altitude simulation test stand, according to China Space News.

Xinhua News Agency reported that this achievement represents a significant advancement in key technologies related to simulating the main deceleration engine of China's manned lunar landing spacecraft. The test evaluated the engine's compatibility with the test stand, which employs cutting-edge steam active ejector technology, as stated by the Academy of Aerospace Propulsion Technology, the system’s developer.

The test stand, equipped with the largest steam ejector pump set in China, can replicate high-vacuum conditions during the engine's full operational window, which lasts for up to 1,000 seconds.
