商业火箭，“芯级回收”走到哪一步了？

Core Viewpoint - The domestic private commercial rocket company, Dongfang Space, is set to complete the first flight of its medium-sized liquid reusable launch vehicle, "Gravity II," by mid-2026, marking a significant advancement in China's commercial space sector [1] Group 1: Technology and Innovation - "Gravity II" features an innovative core-level recovery design aimed at meeting the demands of large-scale satellite networking and commercial high-orbit launches [1] - The core-level recovery technology is customized for commercial space needs, allowing for at least 30 reuses of the rocket body through the use of lightweight, high-strength alloy materials and modular design [2] - The rapid turnaround capability enables the recovered core to be ready for launch again within 48 hours after maintenance, supporting a high-density launch schedule of "one rocket per week" [2] Group 2: Market Context and Competition - The demand for reusable rockets is driven by the urgent need for bulk satellite launches due to the recent surge in low Earth orbit communication satellite constellations [2] - Internationally, SpaceX leads the field with its Falcon 9 rocket, achieving over 200 recoveries and more than 180 reuse flights, demonstrating the operational viability of recovery technology [2] - In China, both state-owned and private companies, including China Aerospace Science and Technology Corporation and Blue Arrow Aerospace, are advancing reusable rocket development, creating a collaborative environment between state and private sectors [3] Group 3: Challenges and Differentiation - The understanding of core-level recovery among domestic commercial space companies is diversifying, with some viewing it as essential for high-frequency near-Earth orbit launches, while others question its economic viability in larger payload scenarios [4][5] - Dongfang Space's approach with "Gravity II" represents a critical capability enhancement, transitioning from solid rocket systems to liquid reusable rockets, which will determine its competitiveness in the medium to large commercial launch market [5]
