Orbital data centres could slash costs and boost sustainability in space

The space industry is pushing forward with plans for orbital data centres. These facilities promise major savings on energy and cooling while improving resilience. Companies are now examining how to make them a practical reality through better sourcing and cost management. Orbital data centres could cut costs by millions each year. Unlike ground-based sites, they use radiative heat dissipation instead of water cooling. This change alone would save substantial sums annually.

Solar power in space offers another advantage. Without atmospheric interference, panels receive near-constant sunlight at higher intensity. Launching 1,000 kg of solar arrays—costing around $2,500 per kg—could generate roughly 500 kW of capacity, making orbital power competitive with large terrestrial facilities when long-term savings are considered.

Regulations for space-based infrastructure are different but more stable. This predictability helps streamline deployment. Orbital systems also provide natural protection from ground-level threats, reducing the need for backup sites and lowering insurance costs.

However, challenges remain. Latency, legal sovereignty, launch risks, and space debris must all be addressed. Effective sourcing strategies—such as consolidating vendors, eliminating wasteful spending, and aligning contracts with uptime and sustainability targets—will be key to overcoming these hurdles. Orbital data centres could transform how companies manage digital infrastructure. By reducing energy expenses, improving resilience, and meeting sustainability goals, they offer a compelling alternative to traditional facilities. The next step is refining sourcing and operational strategies to make them fully viable.
