Recently, Chinese private aerospace company Deep Blue Aerospace announced that its self-developed liquid-propellant reusable rocket, Zhisu-2, is expected to make its maiden flight this year. Powered by a liquid oxygen/kerosene propulsion system, Zhisu-2 features vertical takeoff and landing capabilities and represents a significant milestone in China’s commercial space sector toward reusable launch vehicle technology.The two-stage Zhisu-2 rocket’s first stage is equipped with multiple throttleable liquid oxygen/kerosene engines, enabling precise landing and recovery. Designed to deliver payloads ranging from several hundred kilograms to one metric ton into low Earth orbit, it primarily targets the growing microsatellite launch market. A successful debut would mark a major step forward for China in transitioning reusable rocket technology from testing to practical application, significantly reducing launch costs and enhancing mission frequency and flexibility.Deep Blue Aerospace has previously conducted multiple vertical takeoff and landing tests with its Nebula-1 series rockets, accumulating critical experience in recovery technologies. The development of Zhisu-2 further refines structural design, guidance systems, and thermal protection, laying the groundwork for future larger-scale reusable launch vehicles. Industry experts note that with increasing policy support and market demand, China’s commercial space industry is rapidly advancing toward a new phase of high-quality, sustainable growth.
近日，中国民营航天企业深蓝航天宣布，其自主研发的液体回收火箭“智神星二号”（Zhisu-2）预计将于今年实现首次飞行。该火箭采用液氧煤油推进系统，具备垂直起降与重复使用能力，是中国商业航天在可回收运载技术领域的重要突破。“智神星二号”为两级构型，一级配备多台可变推力液氧煤油发动机，支持精准着陆与回收。其设计目标是将数百公斤至一吨级的有效载荷送入近地轨道，主要面向微小卫星发射市场。此次首飞若成功，将标志着中国在可重复使用火箭技术方面迈入工程应用新阶段，有望大幅降低发射成本，提升商业发射频次与灵活性。深蓝航天此前已通过“星云-1”系列火箭完成多次垂直回收试验，积累了关键技术经验。“智神星二号”的研制进一步优化了结构、控制系统与热防护方案，为后续更大规模的可回收火箭奠定基础。业内专家指出，随着政策支持与市场需求增长，中国商业航天正加速迈向高质量、可持续发展新阶段。
