The environmental cost of putting data centers in space

SpaceX and startups like Starcloud want to put solar-powered data centers in orbit. There are challenges. When SpaceX filed an FCC application earlier this year proposing to launch a million satellite data centers into orbit, the company argued the project would have no meaningful environmental impact. On SpaceX’s website, Elon Musk made the case for space-based AI infrastructure in simpler terms: “It’s always sunny in space,” he wrote, arguing that orbital data centers are “obviously the only way to scale.”
