Recently, Chinese private aerospace company Deep Blue Aerospace released detailed information regarding the failed first recovery attempt of its Zhuque-3 (ZQ-3) reusable rocket. According to the official statement, the test flight took place in June 2024. After successful stage separation, the first stage reignited and began its return trajectory, but encountered an anomaly in the attitude control system during the landing phase, causing it to deviate from the intended path and fail to achieve a soft landing. Preliminary analysis suggests the failure may have stemmed from a delayed deployment response in the landing legs and insufficient adaptability of the navigation algorithm under complex wind conditions. Despite the unsuccessful recovery, the mission successfully validated several critical technologies, including vertical takeoff, high-altitude coasting, atmospheric re-entry, and partial recovery maneuvers—providing valuable data for future iterations. Deep Blue Aerospace stated that software updates to the control system have already been implemented, with another test flight scheduled for the second half of the year. Although not successful, this attempt represents a significant step forward for China’s commercial space sector on the path toward reusable launch vehicles, laying essential groundwork for future low-cost, high-frequency launches.
近日，中国民营航天企业深蓝航天公布了其朱雀三号（Zhuque-3）可重复使用火箭首次回收试验失败的详细情况。据官方通报，此次试飞于2024年6月进行，火箭在完成一级分离后成功点火返航，但在着陆阶段因姿态控制系统出现异常，导致箭体偏离预定轨迹，最终未能实现软着陆。初步分析显示，故障可能源于着陆腿展开机构响应延迟与导航算法在复杂风场下的适应性不足。尽管回收失败，但火箭完成了包括垂直起飞、高空滑行、再入大气层及部分回收控制在内的多项关键技术验证，为后续迭代积累了宝贵数据。深蓝航天表示，已针对问题优化了控制系统软件，并计划在下半年开展新一轮飞行试验。此次尝试标志着中国商业航天在可回收火箭技术路径上迈出重要一步，虽未成功，却为未来低成本、高频次发射奠定了工程基础。
