2024年6月，中国航天科技集团成功完成了长征十二号乙运载火箭的静态点火试验。此次试验在位于内蒙古的某综合试验场进行，标志着该型火箭研制工作取得关键性进展。静态点火试验是火箭首飞前的重要环节，通过在地面固定状态下点火发动机，全面验证其结构、推进系统、控制系统及测控系统的协调性和可靠性。长征十二号乙是在长征十二号基础上改进的新一代中型液体燃料运载火箭，采用液氧煤油推进剂，具备更高的运载效率和环境友好性。其近地轨道（LEO）运载能力可达12吨，太阳同步轨道（SSO）运载能力约7吨，可满足中小型卫星组网、商业发射等多样化任务需求。此次试验成功为后续首飞奠定了坚实基础，也体现了中国商业航天快速发展的技术实力与工程能力。
In June 2024, China Aerospace Science and Technology Corporation (CASC) successfully conducted a static fire test of the Long March 12B launch vehicle. The test was carried out at an integrated test facility in Inner Mongolia, marking a critical milestone in the rocket’s development. A static fire test is a crucial pre-flight validation step, during which the rocket’s engines are ignited while the vehicle remains securely anchored to the ground. This procedure comprehensively verifies the integration and reliability of the propulsion, structural, control, and telemetry systems. The Long March 12B is an upgraded variant of the Long March 12, representing a new generation of medium-lift liquid-fueled rockets powered by environmentally friendly kerosene and liquid oxygen. It boasts a payload capacity of approximately 12 metric tons to Low Earth Orbit (LEO) and about 7 metric tons to Sun-Synchronous Orbit (SSO), making it well-suited for small-to-medium satellite constellations and commercial launch missions. The successful test paves the way for the rocket’s maiden flight and underscores China’s growing technical and engineering capabilities in the commercial space sector.
