AI Heads to Orbit: Building Data Centers Beyond Earth's Limits

Why space could become the new home for AI's insatiable hunger for power and cooling, unlocking exponential growth in inference and beyond.

Space-based computing is emerging as a game-changer for AI's expansion. With earthly data centers hitting walls on energy availability and water for cooling, shifting operations to orbit taps into unlimited solar power and natural vacuum cooling. This approach not only sidesteps terrestrial bottlenecks but also paves the way for massive scaling in AI inference, where demand is skyrocketing as models become everyday tools.

Key Takeaways

• Space offers unlimited, low-cost solar energy without the need for batteries or land permits, producing eight times more power per solar panel than on Earth.

• Cooling in space relies on radiating heat into the void, eliminating the massive water consumption that plagues ground-based data centers.

• Initial focus will be on AI inference tasks, like generating images or running chatbots, which can operate on isolated nodes rather than massive interconnected clusters needed for training.

• Over the next decade, inference compute could dominate AI energy use, potentially doubling every six to twelve months, far outpacing training demands.

• Challenges like radiation hardening and deployable radiators are being solved through innovative engineering, making space viable for high-power chips.

• Launch costs are plummeting with reusable rockets, enabling terawatts of orbital compute capacity without the constraints of Earth's grid or politics.

• By 2035, space might host a small but growing share of new data centers, with full-scale adoption potentially reaching meaningful levels by 2050.
