The sky is filling faster than Europe is learning to manage it. As the EU builds out IRIS2, its planned 290-satellite secure connectivity constellation, and as commercial operators crowd low orbit, the Union is being forced to confront a question it long left to engineers: who keeps the traffic in space from crashing into itself.
The answer is taking shape in the EU Space Act, the bloc’s first attempt at a single rulebook for space activities. Proposed by the Commission, the law would impose common requirements on safety, resilience and environmental sustainability, and crucially it would apply to non-European operators selling services into the EU, not just home-grown firms. The aim is to stop the continent’s twenty-seven national regimes from pulling in different directions while the orbital environment grows more hazardous by the month.
At the heart of the text is debris. Decades of launches have left orbit littered with spent rocket stages and dead satellites, each fragment a potential collision that spawns thousands more. The Act would set rules for choosing orbits, tracking objects, subscribing to collision-avoidance services and disposing of satellites cleanly at the end of their working life. Operators would have to draw up debris-mitigation plans and coordinate launches and re-entries with aviation authorities, treating space less like a frontier and more like managed airspace.
That regulatory push is colliding with an operational reality moving at speed. Earlier this year the EU’s GOVSATCOM service went live, pooling eight satellites from five member states as a bridge to IRIS2, and Norway and Iceland have since signed up to take part. Full IRIS2 operations are not expected until 2030, the same year the Space Act is due to bite, which gives Brussels a narrow window to align an ambitious infrastructure programme with the rules meant to keep it safe.
The strategic backdrop is impossible to ignore. Europe’s dependence on non-European providers for secure communications, exposed sharply by the war in Ukraine, is precisely what IRIS2 is built to fix. Sovereignty in orbit, however, means little if the orbit itself becomes unusable. A single major collision in a crowded band could threaten the very constellation the EU is spending billions to deploy.
Industry reaction has been mixed. Operators broadly welcome a harmonised market that replaces a patchwork of national licences, but smaller firms worry that compliance costs and technical mandates could entrench the incumbents who can most easily absorb them. There is also the perennial tension between writing rules strict enough to matter and flexible enough not to smother a sector Europe is trying to grow.
Critics outside the bloc argue that extending the rules to foreign operators risks friction with partners and could be read as protectionism dressed up as safety. Supporters counter that orbit is a shared commons, and that letting anyone serving European customers ignore debris standards would defeat the purpose entirely.
The deeper test is enforcement. A law that takes effect in 2030 with transitional periods is a statement of intent more than an immediate fix, and orbit will get more crowded in the meantime. Whether Europe can turn a well-drafted rulebook into genuine stewardship of the space around it, before a cascade of collisions makes the question moot, is the wager now being placed.
