Three-Body Constellation Reaches 5 Quadrillion FLOPS With 12 Satellites in Orbit
1 articles · Updated · China Daily · Jul 29
Summary
Twelve computing satellites launched in May 2025 have given China’s Three-Body constellation a combined 5 quadrillion FLOPS, which the project says is the largest on-orbit space-computing capacity so far.
Li Chao of Zhejiang Lab said the system is meant to process data in space as remote-sensing satellites multiply—more than 3,000 could generate about 300 petabytes a day by 2032, overwhelming ground networks and requiring roughly 100,000 Earth-based servers.
Twenty AI models are already deployed on the constellation, including an 8-billion-parameter remote-sensing model, enabling uses such as fire detection, crop-yield monitoring and atmospheric-pollution tracking with faster alerts.
The network links satellites through laser and microwave communications so they can share data and run coordinated tasks such as astronomical observation and short-term weather forecasting largely in orbit.
Three-Body plans to expand to about 100 satellites by 2027 and around 1,000 by 2032, a scale Li said could revisit any point on Earth every three minutes.

Overview
The May 2025 launch of China's Three-Body Computing Constellation marked a new era in space technology, with 12 AI-powered satellites processing data directly in orbit. This edge computing approach lets satellites send concise answers instead of raw images, cutting data transmission by up to 1,000 times and easing bandwidth limits. Powered by solar energy and radiative cooling, these orbital data centers greatly reduce the environmental impact compared to traditional Earth-based centers. However, as mega-constellations grow, they create severe congestion in low Earth orbit, raising the risk of space debris and requiring new autonomous operations and stricter disposal rules to keep space sustainable.
