On the afternoon of January 16, the Long March 12B carrier rocket (CZ - 12B), which was developed by Commercial Rocket Co., Ltd., a subsidiary of the China Aerospace Science and Technology Corporation, successfully underwent a static fire test at the Dongfeng Commercial Space Innovation Test Zone. In the Western aerospace context, a static fire test is a well - established and crucial procedure. It's akin to a full - scale rehearsal before the actual launch. During this test, the entire launch process was meticulously simulated. Key elements, including the fueling of the rocket (a process where the rocket is filled with the appropriate propellants, similar to how a car is filled with gasoline before a journey), ignition (the moment when the engines are set alight to generate thrust, much like starting a car's engine), and timing control (ensuring that all the steps happen at the precisely calculated moments, just as a well - coordinated orchestra follows a strict tempo), were systematically validated. The test results were highly encouraging. All systems of the rocket functioned in a stable manner, with all parameters falling within the normal range. This not only verified the feasibility and reliability of the rocket's design but also set a solid foundation for the upcoming flight tests. It's like building a sturdy house; the static fire test has ensured that the foundation is strong, so the subsequent "construction" (flight tests) can proceed smoothly.
