Environmental organisations have urged the US Federal Communications Commission (FCC) to freeze new licences for orbital datacentres, warning that a gold rush in space-based computing could lead to more than a million satellites crowding the exosphere. The petition, filed this week, argues that without a comprehensive environmental review, the rapid deployment of satellite infrastructure for data processing risks irreversible damage to the space environment and ground-based astronomy.
The concept of orbital datacentres — essentially server racks mounted on satellites to process data in low-Earth orbit — has gained traction among tech giants and startups seeking to reduce latency and bypass terrestrial energy constraints. Proponents claim that space-based computing could slash the carbon footprint of AI training by harnessing solar power beyond the atmosphere. However, critics contend that the environmental cost of launching and maintaining such fleets has been grossly underestimated.
For UK businesses, the development presents a double-edged sword. British firms investing in satellite technology or cloud services could benefit from faster data processing and reduced reliance on energy-intensive onshore datacentres. Yet the regulatory landscape remains fragmented. The UK Information Commissioner's Office (ICO) has yet to issue specific guidance on orbital data handling, while the EU AI Act — which applies to any AI system affecting European users — could impose extraterritorial obligations on UK companies using space-based AI models. Dr Helen Mortimer, a space policy researcher at the University of Leicester, commented: 'Without coordinated international rules, we risk a tragedy of the commons in orbit. The UK should be pushing for a binding environmental impact assessment framework at the UN level before commercial interests lock in unsustainable practices.'
The implications for UK consumers are indirect but significant. Orbital datacentres could enable faster streaming, real-time autonomous vehicle navigation, and more responsive AI assistants. However, the proliferation of space debris — already a growing hazard for satellites and the International Space Station — could eventually disrupt the GPS and broadband services that millions of Britons rely on daily. The UK Space Agency has previously endorsed the 'zero debris' charter, but campaigners argue that voluntary commitments are insufficient to prevent a catastrophic cascade of collisions.
From an economic standpoint, the UK's position as a hub for satellite insurance and space law could be strengthened if it leads on regulation. Conversely, a failure to act might see British companies locked out of the orbital datacentre market if the US or EU impose stricter rules first. The FCC has not yet responded to the petition, but the debate underscores a growing tension between technological ambition and environmental stewardship — a tension that UK policymakers will need to navigate carefully in the months ahead.
