China launched 12 satellites on Wednesday, May 14, 2025, for an on-orbit computing project led by Zhejiang Lab and startup ADA Space. A Long March 2D rocket lifted off from Jiuquan Satellite Launch Center, marking a significant advancement in space-based computing capabilities.
The 12 satellites form the "Three-Body Computing Constellation," designed to process data directly in space, reducing reliance on ground infrastructure. The constellation boasts a combined 5 peta operations per second (POPS) with 30 terabytes of onboard storage. Each satellite is equipped with a domestically developed 8-billion-parameter AI model.
These satellites feature advanced AI and high-speed laser links. One satellite carries a cosmic X-ray polarimeter to detect transient events like gamma-ray bursts. The constellation also supports full inter-satellite connectivity.
ADA Space claims this is the world's first dedicated orbital computing constellation, representing a shift towards satellites as data processors and AI platforms. It's part of the broader "Star-Compute Program" aiming for 2,800 satellites and a computing power of 1,000 peta operations per second (POPS).
This constellation addresses the growing demand for real-time space computing and positions China as a leader in space computing infrastructure. This development may lead to space-based cloud computing and strategic advancements.
The "Star-Compute Program" aligns with China's goal to lead in AI by 2030. Space becomes a key arena for AI application and advancement. This launch was part of a series of launches scheduled for May, involving various rocket types and spaceports.
