Elon Musk has unveiled an ambitious plan to move artificial intelligence infrastructure into orbit. His rocket company SpaceX recently merged with his AI firm xAI. The combined company has filed plans with federal regulators to launch up to one million satellites. These orbital data centers would be powered by solar energy. Musk argues that space is the only viable way to meet growing AI demands.
The proposal addresses a pressing problem that has emerged on Earth. AI data centers consumed approximately 183 terawatt hours of electricity in 2024 alone. A Bloomberg analysis found that electricity costs near data centers had risen by 267 percent. Solar panels in orbit can produce up to eight times more energy than on Earth. Musk predicts that orbital data centers will become more cost-effective within three years.
However, experts have raised significant concerns about the feasibility of this endeavor. Electronics in space are susceptible to cosmic radiation, which can damage sensitive computer chips. A malfunctioning satellite could trigger a cascade of collisions with other orbital objects. Repairing failed equipment in space remains extremely difficult and costly. Deutsche Bank estimates that orbital data centers will not reach cost parity until the 2030s.
Musk is not the only technology leader pursuing this concept. Google has announced Project Suncatcher to test orbital data centers by launching satellites in 2027. Jeff Bezos's Blue Origin has also revealed plans for a constellation of over 5,000 satellites. Had these companies not recognized the limitations of ground-based infrastructure, this orbital competition would not have begun. The outcome of this unprecedented technological race could reshape the future of computing.
