On May 9, the 2nd Aerospace Information Technology Conference opened in Tongxiang, Zhejiang province. During the event, the Aerospace Information Research Institute (AIR) of the Chinese Academy of Sciences (CAS), alongside over 100 research institutes, aerospace enterprises, and universities, jointly released the Initiative on Co-Building the "Space Cloud" Ecosystem. As a co-founding partner, the Computer Network Information Center (CNIC) of CAS is actively participating in this initiative to help build a world-leading, space-based information service system.

Building the "Space Cloud" is a systematic, long-term, and open endeavor. The initiative calls for action across four key areas: building industry consensus, establishing standards, promoting interconnectivity, and deepening demonstration applications. It encourages nationwide collaboration to build a 1,000-satellite "Space Cloud" ecosystem, aimed at significantly improving the intelligent and systematic application of space-based resources.

Currently, China's high-resolution remote sensing satellite technology and the number of its satellites in orbit have both reached an internationally leading level. The development of high-throughput communication satellites and space computing power is also accelerating rapidly. There is a clear trend toward integrating space-based systems—such as remote sensing, communications, and computing—into cloud networks. By enabling in-orbit coordination among various satellites, the "Space Cloud" will shift away from the traditional model of "centralized ground control, single-satellite observation, and data downlink processing." Instead, it will seamlessly integrate scattered space-based resources to create an open, compatible, 1,000-satellite-strong information service system.

As a driving force in the IT development of CAS, CNIC has long been dedicated to the research and application of network communications, cloud computing, and big data. In co-building the "Space Cloud" ecosystem, CNIC will leverage its technical strengths in network communications, cloud computing infrastructure, and data processing services. The Center will provide robust support for drafting "Space Cloud" standards, enabling space-ground network interconnection, and building space-based information service platforms, contributing its expertise to China's growth as an aerospace power.
