China Launches Largest Space Supercomputer: Constellation of 2,800 Satellites Will Change the Future
China entered a new era of space technology on May 14, 2025, when it successfully launched the first batch of 12 satellites for a project known as the Three-Body Computing Constellation from the Jiuquan Satellite Launch Center. This ambitious project represents the first phase in building the most extensive orbital artificial intelligence network in human history. A Long March 2D rocket carried the satellites into orbit, forming the foundation of a system planned to include a total of 2,800 satellites, making it the world's largest orbital AI computing network.

Technical Specifications of the Project
A consortium of three key organizations is behind this important project. The private Chinese space company ADA Space serves as the main technology partner, while the government-backed Zhejiang Lab research institute provides the scientific and research component of the project. The third key partner is the Neijang High-Tech Zone, which provides infrastructure and economic support for the entire initiative. This combination of the private sector, government institutions, and technology zones is developing a new model of cooperation in China's space industry.
The technical parameters of this space-based computing network are truly impressive. The complete constellation will be capable of achieving computing performance of up to 1,000 peta operations per second (POPS), representing one quintillion operations per second. By comparison, the current initial array of 12 satellites already achieves performance of approximately 5 POPS. Each satellite is equipped with an advanced AI model containing approximately 8 billion parameters, enabling it to perform complex analyses and process data directly in orbit without needing to communicate with Earth. The satellites are interconnected by ultra-fast laser links with a capacity of up to 100 gigabits per second, enabling almost instantaneous data exchange across the entire constellation.
Each satellite has a storage capacity of approximately 30 terabytes, enabling vast amounts of data to be stored and processed directly in space. This technology represents a fundamental breakthrough in satellite observation, as traditional systems can transmit only a fraction of the collected data to Earth due to limited communication capacity—more than 90 percent of satellite data never reaches ground-based processing because of capacity constraints. The Three-Body Computing Constellation solves this problem by processing data directly in orbit, dramatically increasing the efficiency of the entire system.
Advantages of Processing Data in Space
A unique characteristic of this project is that, unlike traditional satellites, which merely collect data for subsequent transmission to Earth, these new satellites process raw data directly in orbit using advanced onboard AI systems. This approach offers several key advantages: it reduces dependence on ground-based infrastructure, minimizes latency for time-critical applications, dramatically increases the throughput of usable data, and enables real-time decision-making for applications such as disaster response, climate modeling, astronomical observations, military surveillance, gaming simulations, and the creation of "digital twins."
The constellation will support scientific instruments such as X-ray polarization detectors for cosmic phenomena, including gamma-ray bursts. By processing vast amounts of information locally in space, drawing power from solar panels, and dissipating heat into the vacuum of space, the system promises significant sustainability advantages over ground-based supercomputers, which require enormous amounts of electricity and water for cooling.
Impact on Competition
In terms of strategic implications, this development places China at the forefront of orbital computing technologies. Experts note that it could reshape global technological competition—particularly between China and the United States—and raise new questions concerning cybersecurity and international cooperation. Subimal Bhattacharjee, a defense and cybersecurity expert, commented on the project: "China's launch is a turning point... It is shaking up the global technology rivalry." The project also has open-access ambitions, suggesting potential cooperation with organizations around the world. With thousands more satellites planned over the next several years and the ultimate goal of competing with or surpassing the most powerful ground-based supercomputers, the Three-Body Computing Constellation signals not only technological ambition but also a vision in which the future of cloud computing may literally be above the clouds.
The project represents a shift in how humanity approaches big data processing both on Earth and beyond. Subsequent phases of construction will continue throughout 2025 and 2026, with each launch adding dozens more satellites to the growing orbital network. Full completion of the 2,800-satellite constellation is planned for the end of this decade, when the system is expected to reach its full computing potential and become humanity's most powerful computing system—this time located in space.
