China launches space computing satellite constellation

Published on May 15, 2025

On Wednesday, China successfully launched a Long March-2D rocket from the Jiuquan Satellite Launch Center, deploying the first 12 satellites of its "Three-Body Computing Constellation" into orbit. Developed by Zhejiang Lab in collaboration with global partners, the constellation is designed to eventually comprise thousands of satellites with a combined computing power of 1,000 peta operations per second (POPS). The initial satellites already offer 5 POPS and 30 terabytes of storage, featuring intelligent on-board computing and inter-satellite communication. This space-based infrastructure aims to revolutionize data processing in orbit, enhance AI applications in space, and expand the potential of aerospace technology. The launch also included an X-ray polarization detector for gamma-ray burst research, and plans are underway to deploy over 50 computing satellites within the year.
