朱雀三号重复使用运载火箭发射入轨，回收试验失败

Core Points - The Zhuque-3 Yao-1 rocket successfully completed its flight mission, with the second stage entering the designated orbit [1] - Zhuque-3 is a new generation of low-cost, high-capacity, high-frequency, reusable liquid oxygen-methane launch vehicle developed by Landspace [1] - The rocket features a two-stage design with a diameter of 4.5 meters for both stages and a total length of 66.1 meters [1] Summary by Sections Launch and Design - The Zhuque-3 rocket utilizes a single-core two-stage configuration and is powered by the Tianque series liquid oxygen-methane engines developed by Landspace [1] - The rocket's first stage is equipped with a reaction control system, grid fins, and landing legs for vertical return and reuse after orbital launch [1] Recovery Attempt - The mission included a recovery verification for the first stage, but an abnormal combustion occurred, preventing a soft landing at the recovery site [2] - Despite the failure to achieve the recovery goal, the mission validated the correctness and rationality of the testing, launch, and flight processes, as well as the compatibility of various system interfaces [2] Future Plans - The development team will conduct a comprehensive review of the test process and work to identify the cause of the failure, aiming to optimize the recovery plan for future missions [2] - The data obtained during the flight will serve as a crucial foundation for subsequent launches and the reliable recovery of sub-stages [2]
