SpaceX has filed a sweeping proposal with the U.S. Federal Communications Commission seeking permission to deploy as many as 1 million solar-powered satellites into low Earth orbit to serve as artificial intelligence (AI) data centers powered directly by solar energy—a plan it describes as a way to meet surging AI computing demand, tap near-constant solar power, and even frame as a step toward humanity harnessing the Sun’s full energy potential. According to multiple reports, the filing pitches this massive orbital network as offering cost and energy efficiencies compared with traditional ground-based data centers while relying on SpaceX’s advancing Starship launch system to make such deployment technically and economically possible. Critics and analysts note that the “1 million” figure is widely viewed as an upper-bound regulatory filing strategy, far beyond what’s likely to be approved or deployed, and that such a constellation would dramatically expand orbital congestion given that only about 15 000 satellites currently encircle Earth. The request also comes amid SpaceX’s broader strategic moves in AI infrastructure, including discussions of merging with Elon Musk’s AI company, xAI, and efforts by rival tech and space players to advance competing orbital computing concepts. The proposal is expected to trigger intense regulatory reviews over space traffic management, environmental impacts, and the feasibility of operating compute infrastructure hundreds of miles above Earth’s surface.

Key Takeaways
- SpaceX is petitioning the Federal Communications Commission to authorize up to one million solar-powered satellites designed to function as AI data centers in orbit, leveraging near-constant sunlight and potential efficiencies in power and cooling.
- The figure of one million satellites is broadly regarded as a regulatory starting point rather than a literal near-term deployment target, reflecting SpaceX’s approach to securing spectrum and orbital rights.
- The proposal raises concerns over orbital congestion, regulatory oversight, and technical challenges even as it positions SpaceX to compete aggressively in the expanding AI infrastructure market.
In-Depth
SpaceX’s regulatory filing to the Federal Communications Commission represents one of the boldest and most futuristic infrastructure proposals ever submitted by a private aerospace company. Rather than incremental additions to its existing Starlink broadband constellation, SpaceX’s request seeks authority to launch a truly unprecedented constellation of up to 1 million satellites, each equipped with solar panels and computing hardware to serve as orbital data centers for artificial intelligence workloads. These satellites would rely on solar power harvested above the atmosphere’s attenuating effects, potentially offering near constant generation of electricity and minimizing the massive energy and water requirements that terrestrial data centers face, particularly those powering AI training and inference workloads. The FCC filing frames the idea not merely as a commercial undertaking but as a long-term vision for transforming how humanity computes and harnesses energy, tapping into concepts like the Kardashev scale of civilization advancement.
On a practical level, experts and industry observers view the “1 million” number with skepticism, interpreting it as a regulatory strategy to secure broad design flexibility rather than a definitive plan for launching that exact number of satellites. SpaceX has used similar tactics in past filings, such as when seeking permission for tens of thousands of Starlink satellites, then deploying smaller subsets initially. Current estimates place the total number of human-made satellites in orbit at around 15 000, with SpaceX already operating roughly two-thirds of them through Starlink. A leap to hundreds of thousands—or even a fraction of a million—would represent a seismic shift in orbital traffic and demand rigorous space-traffic management protocols to avoid collisions and mitigate space debris risks.
The proposal is also intertwined with SpaceX’s broader corporate strategy, which appears increasingly focused on AI infrastructure and commercial scaling. Reports indicate that SpaceX is in talks about a merger with xAI, Elon Musk’s artificial intelligence company, which could help align capital and technological development toward space-based computing. This comes at a time when competitors, including Amazon and other space ventures, are pursuing their own orbital computing and data center projects, intensifying competition in what might be the next frontier of AI infrastructure.
Regulators, meanwhile, face the difficult task of balancing innovation and national interest against the potential for orbital congestion, interference with astronomical research, and the environmental and safety implications of large-scale satellite deployments. The FCC will likely review technical, legal, and environmental aspects of the filing closely, and many analysts predict significant revisions to the proposal before any approval is granted. Nonetheless, SpaceX’s bold vision underscores how the convergence of space technology, AI, and renewable power generation is reshaping expectations about where and how humanity will build the backbone of tomorrow’s digital economy.
