China has achieved a milestone in its space exploration journey by successfully testing the third-stage engine of the Long March-10 moon rocket. Developed by the state-owned Academy of Aerospace Liquid Propulsion Technology, the YF-75E engine, which burns liquid hydrogen and liquid oxygen, demonstrated its capability for long-term operation in space. This successful test signifies a major advancement for China's goal to put astronauts on the lunar surface before 2030. The test rig used for the engine trial is the largest in Asia and can simulate high-altitude vertical-flight conditions. The Long March-10 rocket, similar to SpaceX's Falcon Heavy, features a powerful propulsion system with three stages. The rocket will be utilized for China's manned lunar exploration, with plans to have astronauts conduct scientific investigations, collect rock samples, and drive a rover on the moon's surface. Chinese space officials are confident in meeting the 2030 deadline, with manufacturing already underway for key mission components such as lunar landing suits and space vehicles.
