On January 2, 2025, the China Aerospace Science and Technology Corporation (CASC) conducted an impressive five tests on rocket engines in Beijing and Laiyuan, located in North China’s Hebei Province. This series of tests is a crucial component in the ongoing development of rocket engines and plays an essential role in advancing the nation’s major aerospace projects for the year.

One of the highlights was the ignition of a new upper-stage hydrogen-oxygen engine at the 101 Institute of CASC, which successfully operated for approximately 100 seconds before powering down. This achievement confirms that the engine has passed its ground calibration test and is ready for delivery. According to Xia Wei, a CASC professional, the tests not only assessed the engine's overall system coordination but also provided important performance metrics, leading to a declaration of success after thorough data analysis.

In addition to the main propulsion and upper-stage engine tests, the team also conducted trials on the attitude-orbit control engine and executed a liquid-oxygen methane engine test on a specialized dual-station test stand. All tests conducted on that day were reportedly very successful, demonstrating the team's capability to achieve multiple testing runs within a single day. Looking forward, Xia indicated that in 2025, additional research and testing of various engines will focus on endeavors such as deep space exploration and heavy rocket projects, supporting the advancement of China's space goals.
