Overview
As AI technologies increase demand for compute and energy, data centers are predicted to make up nearly half of electricity demand growth by 2030. For the U.S. to maintain its lead in the AI race, it will require terawatts of power—a scale that will challenge power grids across the planet.
But what if the data centers weren’t on the planet at all? Orbital data centers (ODCs) offer a strategic alternative, harnessing near-continuous solar power in low-Earth orbit and processing key data in space. This could reduce dependence on strained power grids, avoid environmental costs, and provide physically separate compute infrastructure for critical national security workloads.
In addition, China is already developing its Three Body Computing Constellation to integrate orbital computing into a broader military and intelligence strategy. This signals that space-based AI infrastructure is not some science fiction plot, but an emergent domain for geopolitical competition.
What are the strategic advantages of ODCs beyond moving power-intensive compute off-planet? How do these advantages line up with the technical requirements and costs of creating and maintaining ODCs? What is the current state of China’s ODC strategy, and how does it connect with China’s AI ambitions?
This new NSDPI paper explores these questions and more by analyzing the technical potential and national security implications of ODCs.
Key Takeaways
- Increasing power demand, rising energy costs, and limited scalability on Earth are key motivations for moving data centers into space. Approximately 95% of solar energy is lost by the time it reaches Earth, and computing in orbit could capture far greater efficiency.
- China is reinforcing its space ambitions by building partnerships and telemetry, tracking, and command infrastructure across Africa, South America, and other regions to support its expanding orbital presence.
- Establishing and maintaining a U.S. ODC advantage will require regulatory modernization and clear strategy for securing resilient AI compute in orbit.
