Musk Says Space-Based Data Centers Could Become Cheaper Than Earth Facilities Within Three Years

Elon Musk has suggested that placing data centers in orbit could soon be more cost-effective than operating them on Earth, a claim that has accelerated debate within the AI infrastructure community.

‍

In a recent tweet, Musk argued that terrestrial data centers are approaching practical limits, citing constraints around power, access to fresh water for cooling, and available real estate. Supporters of orbital designs say space-based facilities could ease strain on local energy systems and eliminate the need for water entirely.

Cooling remains a major factor in today’s data center operating costs. Some facilities dedicate as much as 40 percent of their total energy consumption to cooling systems. In orbit, heat can be dispersed directly into space through infrared radiation, avoiding water usage and reducing restrictions on equipment density.

‍

Advocates also point to falling launch costs as a key enabler. The price of sending hardware to orbit has dropped significantly in recent years, a trend driven in part by SpaceX’s reusable launch vehicles.

‍

Industry observers predict that workload migration could begin as early as 2026 for applications that do not rely on extremely low latency. Companies have already started exploring the concept; StatCloud has deployed infrastructure in orbit, and Google is reportedly evaluating similar approaches.

Some analysts warn that early movers could gain a substantial advantage if orbital compute becomes viable at scale, potentially widening technological gaps between countries and companies competing in the AI sector.
