Orbital Compute Becomes Cheaper If Launch Costs Fall Below $500/kg
Philip Johnston, Starcloud’s co-founder and chief executive, argues that AI data centers could become cheaper in orbit than on Earth if launch costs fall to about $500 per kilogram. His case rests on continuous solar power in a dawn-dusk orbit, avoiding land and battery costs, and using constellations of optically linked satellites for inference workloads. Starcloud’s plan, he said, starts with an orbital GPU proof point and points toward an 88,000-satellite network delivering roughly 20 gigawatts of compute capacity.
