The trend – The race to commercialise near-Earth space is outpacing the rules designed to govern it. With satellite numbers surging and debris accumulating, the orbital environment is under mounting strain. We often think of space as infinite, however the area between Earth and the moon is finite.

A crowded sky – Over 14,900 active satellites currently circle the planet, with SpaceX's Starlink accounting for roughly 63% of them. The European Space Agency's (ESA) 2025 Space Environment Report estimates more than 50,000 objects larger than 10 cm are in orbit, alongside 1.2 million exceeding 1 cm and some 140 million fragments of 1 mm, all capable of inflicting extreme damage at orbital speed.

Rights to space – Proposals filed in January with the US Federal Communication Commission requested permission for Starlink to send up one million additional AI satellites, with Blue Origin founded by Jeff Bezos separately seeking approval for up to 51,600. This also raises questions about rights to space, with the European Space Agency concerned about unequal satellite distribution due to dominating companies. China plans to launch satellite constellations to rival Starlink, aiming for 15,000 by 2030, demonstrating a race for satellite space and calls for stricter regulations on commercial space activities.

Chain reaction – Scientists warn of Kessler syndrome – a self-perpetuating cascade of collisions that could render entire orbital bands unusable for future generations due collisions causing chain reactions, repeatedly breaking debris into smaller particles. ESA cautions that even a total halt to new launches would not reverse the debris count increase, as fragmentation events multiply debris faster than natural atmospheric re-entry removes it. Researchers have now proposed a so-called CRASH Clock to quantify how close humanity is to a catastrophic, irreversible collision event.

Current collisions – Two Starlink satellites suffered "anomaly" events within months of each other – satellite 35956 in December 2025 and 34343 in March 2026 – each releasing trackable debris into orbit. Tracking firm LeoLabs attributed both to internal energetic sources rather than external collisions, likely propulsion or battery failures and flagged the recurring pattern as a concern given the sheer scale of objects already overhead. China also reported having to manoeuvre its space station in 2021 to avoid colliding with a Starlink satellite.

Atmospheric toll – The environmental impact of increased satellite launches is understudied. An experiment found around 10% particles in the stratosphere contained metal originating from space activities. It is still unknown what impact this metal will have on the chemistry of our ozone layer and atmosphere. However, it is speculated that increased accumulation of re-entry material will cause temperature anomalies up to 1.5C in the middle to upper atmosphere, impact wind speeds and deplete the ozone which protects the earth from radiation.

Inspecting lifecycles – Satellites have a life span of five years before they are deliberately re-entered into the earth’s atmosphere to burn up. What goes up must come down, and we need to start thinking of the environmental costs of this largely unquestioned process. Active debris removal has been highlighted by the ESA as essential to ensuring orbital space remains accessible.

‍

The clean-up economy – Solutions to satellite pollution are advancing demonstrating a fast-growing market. Japan's Astroscale Holdings is developing magnetic capture systems to dock with and de-orbit defunct satellites, while Luxemburg-based ClearSpace is pursuing robotic grappling technology alongside refuelling and life-extension services. UK start-up Paladin Space, backed by the ESA Business Incubation Centre, is building the world's first reusable debris-capture system developed with space robotics and vision-based navigation.

On the wire – Orbital space has long been treated as a free resource with no clean-up obligation. That is changing. Debris removal and satellite servicing represent a growing investment opportunity as active orbital management becomes a commercial necessity.
