Introduction to the Mission and its Significance

China has launched a Long March-2D rocket, sending 12 satellites into orbit as the first batch of the “Three-Body Computing Constellation,” the core for a space supercomputer powered by Artificial Intelligence (AI).

Background and Context

As global data centers consume increasing amounts of electricity, with estimates suggesting over 1,000 terawatt-hours annually by 2026—equivalent to Japan’s total electricity consumption—the limitations of terrestrial data processing become apparent. Traditional methods involve satellites collecting data in space, then transmitting it to Earth for processing. This method is constrained by the availability and bandwidth of ground stations, resulting in less than 10% of collected data typically reaching Earth with significant delays.

High-Speed Data Processing in Space

According to Guangming Daily, each of the 12 satellites can process up to 744 quadrillion operations per second. Connected via high-speed laser links with data transfer rates of up to 100 gigabits per second, the initial network offers a combined computational power of 5 petaoperations per second (POPS) and 30 terabytes of onboard storage.

Key Players and Their Roles

Zhejiang Lab, a government-backed research institute in Zhejiang province, led the development of onboard AI computers and space models driving the constellation’s computational capabilities.

Guoxing Aerospace, a Chengdu-based developer of AI satellites, was responsible for developing the intelligent satellite platforms and overseeing the assembly of the satellites.

HiStarlink, a laser communications startup, developed the high-speed optical terminals enabling data transfer between satellites in the network.

Impact and Future Prospects

This mission marks a significant milestone in China’s space computing capabilities, aiming to build a network of thousands of satellites with a total computational power of 1,000 petaoperations per second (POPS). The constellation will enable real-time data processing in orbit, accelerating AI development in space.
