With backing from AI chipmaker Nvidia, a startup called Starcloud launched a high-powered Nvidia GPU into outer space aboard a SpaceX rocket last month. While data centers on Earth can be cooled using water and air, things get more complicated when it comes to cooling AI chips in outer space. “Orbital data centers can leverage lower cooling costs using passive radiative cooling in space to directly achieve low coolant temperatures,” the white paper reads. Nonetheless, a growing number of firms believe running data centers in orbit is the answer. “Our responsibility is to keep it that way.”More on orbital data centers: China Is Building an AI-Powered Supercomputer Network in Space
