HAWTHORNE, Calif. — Elon Musk has sketched one of his most ambitious long-range ideas yet: a mass driver on the surface of the Moon that could hurl superintelligence satellites into deep space, adding what he described as more than one petawatt of new capability every year.
A Launcher on the Moon
A mass driver is an electromagnetic accelerator that flings payloads along a track rather than lifting them with rockets. On airless, low-gravity worlds like the Moon, the concept becomes far more attractive: without an atmosphere to fight and with a fraction of Earth's gravity, a track-based launcher could accelerate spacecraft to escape velocity using electricity alone. Musk said such a system, feeding a steady stream of compute satellites outward, could deliver capability that would "far exceed the best case value of Earth's economy."
The comment came in a weekend reply to a widely shared SpaceX financial model, and it extended a forecast Musk made the night before about the rise of orbital computing. It also dovetails with the Starship program that would make any lunar industry possible; Musk has previously said it would take roughly six to eight Starship flights to land on the Moon, the same transport backbone a mass-driver project would eventually lean on.
Compute as the Payload
The vision fits a pattern in Musk's recent thinking, which increasingly treats raw computing power as the ultimate product. SpaceX's planned Star Mind AI satellites are designed for large in-orbit compute formations, with each craft reportedly exceeding 250 kilowatts of solar power. Stack enough of them, the argument goes, and space becomes the natural home for artificial intelligence — cooled by the void, powered by uninterrupted sunlight, and free of terrestrial land and grid limits.
