Space debris pose a hazard to operations in outer space. This fact has been widely recognized by the scientific community. General measures necessary to minimize the hazard are well understood and have been clearly spelled out. The power to put relevant measures into force or to agree at least on unbinding recommendations rests, because of the global character of outer space, with international organizations, specifically with the United Nations. Up to 1992, proposals to put the question of space debris on the agenda of the UN Committee on the Peaceful Uses of Outer Space (COPUOS) have not been successful. In the meantime, the risk of fatal collisions of valuable satellites with space debris keeps increasing.
