China Launches First Satellites for World's First Space-Based Supercomputer
China Launches First Satellites for World's First Space-Based Supercomputer
On May 14, 2025, China took a monumental step in space technology by launching 12 satellites from the Jiuquan Satellite Launch Center, marking the beginning of the world's first orbital supercomputing network, dubbed the "Three-Body Computing Constellation." This ambitious project, led by Chinese startup ADA Space in collaboration with Zhejiang Lab and the Neijiang High-Tech Zone, aims to deploy a total of 2,800 AI-powered satellites by 2028, creating a space-based supercomputer capable of rivaling Earth's most powerful computing systems.

A New Era of Space-Based Computing
Unlike traditional satellites designed for sensing or communication, these 12 satellites are equipped with advanced AI systems, each capable of processing 744 trillion operations per second (TOPS) and featuring an 8-billion-parameter AI model. Together, the initial cluster delivers a combined computing power of 5 peta operations per second (POPS) and 30 terabytes of onboard storage. The constellation is projected to scale up to 1,000 POPS, equivalent to one quintillion operations per second, potentially surpassing the capabilities of top terrestrial supercomputers like the El Capitan system in California, which achieves 1.72 POPS.
The satellites are interconnected through high-speed laser links, enabling data transfer rates of up to 100 gigabits per second. This allows for real-time data processing in orbit, reducing reliance on Earth-based data centers and minimizing data transmission bottlenecks, as less than 10% of space-collected data currently reaches Earth due to bandwidth limitations. By processing data in space, the constellation enhances efficiency, reduces latency, and improves decision-making speed for applications like disaster response, urban planning, and astronomical research.
Strategic and Environmental Advantages
The Three-Body Computing Constellation leverages the unique conditions of space to overcome limitations of ground-based computing. The vacuum of space provides natural cooling, eliminating the need for resource-intensive cooling systems used by terrestrial data centers, which consumed 19.7 billion liters of water at Google's facilities alone in 2022. Additionally, the satellites utilize unlimited solar energy, reducing the carbon footprint and reliance on Earth's power grids. These environmental benefits align with global efforts to address the escalating energy demands of data centers, projected to consume over 1,000 terawatt hours annually by 2026.
Jonathan McDowell, a space historian and astronomer at Harvard University, noted, "Orbital data centers can use solar power and radiate their heat to space, reducing the energy needs and carbon footprint." This innovative approach positions China at the forefront of sustainable computing and space technology.
Scientific and Practical Applications
The satellites carry advanced payloads, including a cosmic X-ray polarimeter developed by Guangxi University and the National Astronomical Observatory of the Chinese Academy of Sciences, enabling the study of transient cosmic events like gamma-ray bursts. The constellation's ability to generate 3D digital twin data also supports applications in emergency response, gaming, and tourism. By processing data in orbit, the system minimizes data leakage and enhances decision-making, offering strategic advantages for both civilian and defense applications.

Global Implications and Competition
The launch has sparked global attention, with some analysts viewing it as a move to assert dominance in the space-based computing race. Posts on X reflect excitement about the project, with users describing it as a "new stage of planetary infrastructure" and a "digital brain in orbit." However, the initiative also raises concerns about technological competition, with some sources suggesting it could challenge U.S. interests in space if China further advances its supercomputing capabilities.
Wang Jian, director of Zhejiang Lab, emphasized the project's goal to scale computing power from teraflops to petaflops and achieve seamless satellite interconnectivity, akin to the internet's linking of individual computers. This vision underscores China's ambition to redefine data processing and establish a new paradigm for the global space economy.
Challenges and Future Outlook
Despite its promise, the Three-Body Computing Constellation faces challenges, including the complexity of coordinating a 2,800-satellite network and ensuring reliable inter-satellite communication. The project's success will depend on overcoming these technical hurdles and maintaining cost-effective launches, which have become more feasible due to China's advancements in reusable rocket technology and private-sector involvement since 2014.
As China continues to deploy additional satellites, the constellation could transform fields like disaster response, urban planning, and scientific research, while reducing strain on Earth's infrastructure. With plans to complete the network by 2028, the Three-Body Computing Constellation represents a bold leap toward a future where computing power transcends terrestrial boundaries, heralding a new era of space-based innovation.
