我国商业航天企业即将迎来一个新的里程碑。据中科宇航官方消息，该公司与中国科学院微小卫星创新研究院（以下简称卫星创新院）近日在上海召开了中国空间站低成本货物运输系统总体方案讨论确认会。会议明确了由中科宇航自主研发的力箭二号液体运载火箭将发射卫星创新院自主研制的低成本货运飞船产品。这次任务标志着我国商业航天企业首次参与中国空间站的低成本货物运输工程研制及发射任务。
力箭二号火箭预计于2025年执行首次飞行任务，进行在轨全流程考核验证。此次任务还计划搭载低轨互联网星座卫星。力箭二号是一款中型液体运载火箭，采用通用芯级直径3.35米，总长53米，起飞质量628吨，起飞推力766吨。火箭具备太阳同步轨道、近地轨道、转移轨道发射能力，将成为我国低成本货运飞船、卫星互联网组网、空间科学卫星发射以及深空探测任务的主力火箭。
此前在2023年5月，中国载人航天工程办公室发布了中国空间站低成本货物运输系统总体方案征集公告。中科宇航与卫星创新院针对任务需求，开展船箭联合论证和关键技术攻关，成功入围方案竞标，获得了中国载人航天工程总体的支持，进入了方案详细设计阶段。
此次低成本货运任务的实施，将有力推动我国商业航天事业的发展，进一步提升我国在国际航天领域的竞争力。此外，这也将有助于降低空间站运营成本，为我国空间站的可持续发展奠定基础。

China’s commercial aerospace industry is set to reach a new milestone with the launch of the Li箭二号 rocket, which will transport a low-cost cargo spacecraft developed by the Chinese Academy of Sciences’ Micro Satellite Innovation Institute. The confirmation meeting for the overall solution of China’s low-cost cargo transportation system for the space station was recently held in Shanghai.
The Li箭二号 rocket is expected to conduct its first flight mission in 2025, marking the first time a Chinese commercial aerospace company has participated in the development and launch of a low-cost cargo mission for China’s space station. The mission will also involve the launch of low-orbit internet constellation satellites.
The Li箭二号 rocket is an intermediate-sized liquid rocket with a diameter of 3.35 meters, a total length of 53 meters, a take-off mass of 628 tons, and a take-off thrust of 766 tons. It has the capabilities of launching cargo spacecraft into sun-synchronous orbits, low-earth orbits, and transfer orbits. The rocket will become the main force for China’s low-cost cargo spacecraft, satellite internet networking, space science satellite launches, and deep space exploration missions.
Previously, the China Manned Space Program Office released a solicitation for the overall solution of China’s low-cost cargo transportation system for the space station in May 2023. China Aerospace Science and Technology Corporation and the Micro Satellite Innovation Institute conducted joint research and development on the key technologies, successfully bidding for the project, and received overall support from the China Manned Space Program, entering the detailed design stage.
The implementation of this low-cost cargo mission will significantly promote the development of China’s commercial aerospace industry and enhance China’s competitiveness in the international aerospace field. Furthermore, it will help reduce the operating costs of the space station and lay a solid foundation for the sustainable development of China’s space station.
