China just launched the largest orbital computing network ever attempted. On May 14, 2025, Beijing deployed the first 12 satellites of a planned 2,800-unit constellation designed to operate as AI-powered data centers in space. Each satellite carries 744 trillion operations per second of compute power, linked by 100 Gbps laser interconnects. The system runs an 8-billion parameter model onboard and stores 30 terabytes locally. This is not a science demo. It’s a commercial rollout backed by Guoxing Aerospace and Zhejiang Lab, with full support from the Chinese government.
The project is called the Three-Body Computing Constellation. It’s designed to bypass the limitations of land-based infrastructure: no cooling towers, no real estate, no water consumption. Solar power drives the entire network. Data is processed in orbit, not on Earth. That means faster response times, lower latency, and reduced environmental impact. The satellites are built for edge computing, drone coordination, military analytics, and autonomous systems. They also carry remote sensing payloads and space X-ray polarimeters for astrophysics.
The full constellation will deliver 1,000 peta operations per second. That’s one quintillion operations per second. Once complete, it will rival the most powerful ground-based supercomputers. The U.S. has no equivalent in orbit. Microsoft shelved its underwater Project Natick. Lonestar’s lunar data center is still in planning. Starcloud’s satellite cluster won’t be operational until mid-2026. China is already online.
The Shanghai phase of the project uses wind-powered undersea data centers to supplement orbital compute. Hailanyun’s offshore facility, six miles off the coast, is set to go live in September. It uses 30% less electricity than land-based centers and is connected to a 97% renewable energy source. The first module holds 198 racks and can train GPT-3.5 scale models in under 24 hours.
China’s AI infrastructure is now layered: undersea, orbital, and terrestrial. The U.S. is still debating permitting rules for land-based data centers. Trump’s administration is preparing executive orders to accelerate domestic buildouts, but the gap is growing. China moved from pilot to deployment in under 30 months. Microsoft’s Natick never left the test phase.
This is not just about compute. It’s about control. Orbital data centers bypass export controls, sanctions, and terrestrial chokepoints. They operate above the regulatory grid. That’s strategic leverage. And Beijing knows it.
