Zhuyu Space Secures Funding for Reusable Rocket Tech

A nascent Chinese aerospace venture, Zhuyu Space, has successfully closed a significant funding round, underscoring investor confidence in its innovative approach to small satellite launch solutions. The company, founded by the exceptionally young entrepreneur Zhang Zihan, announced the completion of a tens of millions of RMB angel round, led by MinYin International. This latest infusion of capital follows a prior seed round from Matrix Partners China late last year, marking two successful financings within a six-month span.

Zhuyu Space is charting a distinct course in the rapidly expanding commercial space sector by focusing on reusable, medium-sized launch vehicles. Unlike the industry's current trend towards massive rockets for mega-constellations, Zhuyu Space is targeting the underserved market for smaller satellites. Their flagship rocket, codenamed 'Fission', is designed for payloads under 450 kilograms, aiming to drastically reduce launch costs to approximately one-quarter of the industry average for comparable services. This strategic positioning addresses a critical gap for small satellite operators who currently face long wait times or prohibitive costs with existing launch options.

At the heart of Zhuyu Space's technological ambition is its proprietary liquid oxygen-methane rocket engine, 'Han Tian'. The company has developed a novel electric pump-fed cycle, a departure from the more common gas generator cycle used in most large-thrust engines. This design choice, which required an initial investment of approximately 400,000 RMB for the prototype engine, offers significant advantages in reliability and thrust vectoring capabilities crucial for reusable rockets. The electric pump system eliminates the complex and failure-prone turbine pump assembly found in traditional engines, while its ability to achieve thrust modulation down to 18% is ideal for the precise control needed during vertical landing maneuvers.

The company's rapid progress is a testament to its lean operational model and the focused execution of its young team. Founded in 2025, Zhuyu Space has already achieved critical milestones, including the successful 20% low-thrust full system hot fire test of its 'Han Tian' engine in January. A full-power test is imminent, with plans to scale to small-batch production of 15-20 units by the third quarter of 2027. This engine development is a foundational step towards their 'Fission' rocket, which aims to provide dedicated, cost-effective launch services, akin to a 'private space taxi', for small satellites, enabling greater flexibility in orbital selection and significantly reduced launch intervals.

The backing from prominent investors, including MinYin International, Century Huatong, Songhe Capital, and Beidou Group, alongside the earlier support from Matrix Partners China, highlights the market's recognition of Zhuyu Space's disruptive potential. This funding will be instrumental in accelerating the development and testing of the 'Fission' rocket, with a maiden flight targeted for late 2027. The company's long-term vision extends to larger launch vehicles, with 'Fusion' envisioned as a future capability, building upon the data and technological maturity gained from the 'Fission' program.

Zhang Zihan, the founder, brings a unique blend of precocious talent and rigorous rationality to the venture. Having decided to pursue commercial spaceflight as early as high school, he accelerated his education to dedicate himself to this pursuit. His leadership emphasizes efficiency and a flat organizational structure, fostering cross-disciplinary collaboration to minimize communication overhead and maximize development velocity. This approach is critical in an industry where time-to-market and cost efficiency are paramount for success, especially for a company aiming to redefine the economics of small satellite deployment.
