Overview

• China launched 12 AI-equipped satellites on May 14, 2025, as part of ADA Space's Star Compute program to build a space-based supercomputer network.
• The satellites collectively deliver 5 peta operations per second (POPS) of computing power and feature 8-billion-parameter AI models capable of 744 tera operations per second each.
• The network uses high-speed laser communication at 100 Gbps and shares 30 terabytes of onboard storage for seamless interconnectivity and data processing.
• In-orbit data centers reduce reliance on Earth-based infrastructure, overcoming bandwidth bottlenecks and improving energy efficiency through solar power and radiative cooling.
• The constellation supports dual-use applications, including scientific research with X-ray polarization detectors and commercial uses like 3D digital twin generation for urban planning and disaster response.
