SpaceX is advancing its Starmind plan to deploy massive space-based AI computing power. Analyst Jeff Pu of GF Securities estimates the company will reach 5 gigawatts of capacity by 2028, utilizing 10,000 NVIDIA Kessel racks powered by Vera Rubin AI systems.
The Kessel racks are compact 9U horizontal versions of the NVL72 platform, standing 16 inches tall. Each AI1 satellite supports a 250-kilowatt payload, with next-gen models reaching 400 kW. Elon Musk confirmed SpaceX is modeling these GPUs for orbital use.
This infrastructure targets a massive $28.5 trillion market through thousands of specialized spacecraft. By managing 4,000-watt thermal loads via aluminum radiators, SpaceX aims to transform its Starlink constellation into a global orbital supercomputer.
