Artificial satellites usually play a role in fields such as communications, navigation, remote sensing, and scientific exploration. Today, Chinese scientists are trying to give satellites an additional “brain” — sending computing power to space as well. So why do we have to “throw” our computing power into the sky? In May 2025, China launched the world's first space computing satellite constellation “Star Arithmetic” into space. The constellation launched 12 satellites. Each satellite is equipped with a space-borne intelligent computing system and an interplanetary communication system, and has space computing and space interconnection capabilities. In the future, it is possible to form a unified computing power supply through star clusters or star clusters. Ultimately, we hope to directly build a very large computing power center in space: we may build a spacecraft with a side length of 4,000 meters x 4,000 meters in the middle of space to provide unlimited computing power. It has actually set up a computing infrastructure in the middle of space to provide computing power services for everyone. Zheng Wen, a researcher at the Institute of Microsatellite Innovation of the Chinese Academy of Sciences, said that sending computing power to heaven is a key step in achieving autonomous intelligence. For example, let the robotic arm of the China Space Station have a “brain” that can calculate, thereby achieving the goal of replacing astronauts in carrying out extravehicular operations.
