Elon Musk, during a presentation for SpaceX's public listing, indicated that one motivation for taking the company public is to raise capital for a capital-intensive, large-scale project: the construction and operation of artificial intelligence data centers in orbit.
Musk stated that such orbital data centers "will become a core vehicle for expanding AI computing power." Deploying data centers in space could also help companies avoid community opposition often encountered with ground-based construction and the various forms of pollution associated with supporting power plants.
He remarked, "Almost no one wants a power plant built near their home. If we are to double the entire electricity consumption of the United States — with the average U.S. power load being about 500 gigawatts — the number of power plants would need to double accordingly."
He envisions that equipment in space could rely on solar power for round-the-clock electricity, allowing the scale of computing power to "far exceed the upper limits of ground-based power generation capabilities."
However, orbital data centers currently lack mature, real-world examples and conceal a series of complex risks.
The cost of launching electronic equipment for AI model training and inference into orbit is extremely high, energy consumption is massive, and precise temperature control is required; meanwhile, dissipating heat from equipment is far more difficult in the vacuum of space than on the ground.
Peter Barrett, a general partner at venture capital firm Playground Global, believes that the feasibility of satellite projects carrying computing equipment would significantly increase only if traditional semiconductors were replaced with superconducting logic chips.
He stated bluntly, "Proceeding with their current plan is completely unrealistic. However, since this project is fundamentally unlikely to get off the ground, it doesn't constitute a real problem."
Of course, Space Exploration Technologies is not the only company exploring orbital data centers. Alphabet, Google's parent company, has a similar goal with its "Project Sunroof," but SpaceX's proposed timeline for implementation is notably aggressive.
According to disclosures in SpaceX's prospectus, the company plans to launch its first batch of in-orbit satellites capable of providing computing power for large AI models as early as 2028.
