Satellite makers and operators must be held responsible for the growing hazard of space debris, according to experts who say a legally binding global treaty must be thrashed out to protect the orbital environment.
With the number of satellites rising dramatically, the agreement would make manufacturers and users responsible for de-orbiting defunct hardware and cleaning up any debris created when orbiting objects slam into one another.
