The Disappearing Sky
Some months ago, an American astronaut accidentally let a tool escape into orbit, eliciting concern about its hazardous potential as a hurtling object that could destroy an expensive satellite or even threaten lives aloft. Shortly afterwards, China blew up one of its satellites, immediately doubling the type of fine orbiting debris that is dangerous because it is hard to track.
Once again the world became aware of the strange situation emerging in our skies. The sky is a unique domain, and one that is inadequately regulated. With the advent of global pollutions and technologies, remedying this is becoming an increasingly urgent problem.
In most cases, the laws for skies mirror those governing the world’s oceans. Oceans belong to everyone except those near landmasses, which are managed in a similar manner to the country's land-bound borders. As a result, the sky is usually conceptualized in terms of traffic. Airliners and fighter planes operate in “controlled” air close to the ground, while nationality is supposed to matter less the higher you go. Fragile treaties that cover this are enforced mostly by the fact that few nations can afford to place assets that high.
