Low Earth orbit, the band of space within a couple of thousand kilometres of the surface, has become crowded. Falling launch costs and smaller satellites have made it possible for companies and countries to deploy large constellations for communications, imaging and research.

Crowding brings risk. Satellites and debris travel at enormous speeds, so even small fragments can destroy a spacecraft on impact. Each collision creates more debris, raising the chance of further collisions — a cascade that experts have warned about for decades.

Rules of the road

There is no single traffic controller in orbit. Operators share tracking data and coordinate manoeuvres, but practices vary. International guidelines encourage operators to remove satellites from orbit at the end of their lives, and some regulators now require it within set periods.

Space is vast, but the useful orbits are not.

Astronomers have raised a separate concern: reflective satellites can streak across telescope images. Operators have experimented with darker coatings and orientation changes to reduce the effect.

The coming years will test whether cooperation can keep pace with growth — or whether binding international rules will be needed to keep orbit usable for everyone.
