研报 | 可回收技术有望降低火箭发射成本，全球大厂正加速推进布局

Core Insights - The article discusses the increasing demand for satellite deployment by Starlink and the U.S. Space Force, leading to a shift in rocket manufacturers like SpaceX towards full rocket recovery technology [2][6] - The average launch cost for expendable rockets is between $110 million and $180 million, while partially reusable rockets cost around $6.7 million. Full recovery technology aims to reduce costs to between $2 million and $5 million [6][7] Group 1: Rocket Types and Costs - Expendable rockets have a complex structure and do not require recovery fuel, but their costs are significantly higher [3] - Partially reusable rockets, like SpaceX's Falcon 9, lower launch costs to approximately $6.7 million but still have limitations on payload capacity due to fuel reservation for recovery [3][7] - Fully reusable rockets, such as SpaceX's Starship, aim to drastically reduce costs to $2 million to $5 million, although they require additional investment in specialized recovery platforms [3][6] Group 2: Technological Developments - SpaceX is leading the commercial rocket launch sector in the U.S. and has made advancements in using liquid methane for its Starship's second stage to reduce cleaning times and overall launch costs [7] - The China National Space Administration (CNSA) is also actively developing its rocket launch plans, focusing on the Long March series to execute national-level missions while optimizing recovery efficiency [7] - Challenges remain in the recovery technology, such as the need for additional fuel in partially reusable rockets and the costs associated with building recovery platforms for fully reusable rockets [7]
