"Space data centers" refer to data storage and processing facilities that are located in outer space or designed to operate in space environments. The concept involves deploying computing infrastructure—such as servers, data storage units, and networking equipment—aboard satellites, space stations, or specialized spacecraft. The main goals of space data centers include reducing latency for space-based operations, improving data transmission efficiency between Earth and space systems, enhancing environmental sustainability by using the cold vacuum of space for cooling, and supporting data-heavy applications like Earth observation, space exploration, and global communications.
