Elon Musk said he wants to see an electromagnetic “mass driver” built on the Moon as part of a broader plan to manufacture artificial intelligence satellites in space, outlining the vision during a SpaceX presentation on its “Terafab” initiative, which aims to scale global chip production.
“I just wanna live long enough to see the mass driver on the Moon,” Musk said following the presentation, describing the concept as a key step toward scaling computing power in space. He later reiterated the idea in a post on X, writing, “Mass drivers on the Moon!”

The SpaceX video referenced “electromagnetic mass drivers on the Moon,” a system designed to launch materials using electromagnetic acceleration rather than traditional rockets. Musk said the approach could take advantage of the Moon’s lack of atmosphere and lower gravity—about one-sixth of Earth’s—to send payloads into space more efficiently.
“You don’t need rockets on the Moon,” Musk said during the presentation. “You can literally accelerate it to escape velocity from the surface,” he added, arguing that such a system would significantly reduce the cost of transporting materials into orbit and beyond.
Musk linked the concept to a broader effort to scale artificial intelligence infrastructure, describing a path from current terawatt-level computing toward what he called “petawatt” levels of power. He said a lunar-based launch system could help enable the deployment of large volumes of solar-powered AI satellites into deep space.
The proposal builds on SpaceX and xAI’s “Terafab” initiative, a planned large-scale chip manufacturing effort aimed at meeting growing demand for AI hardware. In the same presentation, the company outlined the need for massive increases in computing capacity, including chips for robots, satellites and data centers, suggesting current global production would not meet projected demand.
Musk has previously discussed the idea of building a factory on the Moon to manufacture AI satellites, including a system resembling a giant catapult to launch them into space, according to The New York Times. The report said the facility would serve as part of a longer-term effort to expand computing infrastructure beyond Earth.
He has described the Moon as a potential stepping stone for broader space development, including future missions to Mars and beyond, as SpaceX and xAI increasingly align their efforts around computing and energy infrastructure in space.
Some observers reacted to the proposal on social media. Peter Hague, an astrophysics PhD and software engineer, wrote in response to SpaceX’s announcement that “if they pull this off, it will be remembered forever,” contrasting it with what he described as the short lifespan of most news events.
Musk did not provide a timeline for building a lunar mass driver or factory. He has previously made ambitious projections about new technologies that did not materialize on schedule, and the technical and logistical requirements for such a system remain substantial.
The concept would depend on continued reductions in launch costs, advances in robotics and manufacturing, and significant increases in chip production capacity, all of which Musk said are necessary to support large-scale AI systems in space.
