The source describes an early-stage experiment by the startup Starcloud, which successfully launched the first Nvidia H100 GPU into space inside a small satellite. This mission aims to test the performance, power usage, and cooling needs of high-performance chips in orbit as a foundation for their ultimate goal: constructing enormous orbital data centers powered by continuous solar energy. Starcloud envisions massive facilities hosting millions of GPUs in a sun-synchronous orbit to maximize efficiency by eliminating the need for batteries or nighttime power generation. Achieving this ambitious project, which involves launching facilities weighing thousands of tons, is contingent upon future reductions in launch costs made possible by technologies like SpaceX’s Starship.
