ESA SP-1301 Space Debris Mitigation: Implementing Zero Debris Creation Zones
For several decades, orbital debris have been identified as a serious concern! This orbital debris potentially threatens future space missions, mainly in Low Earth Orbits and in Geostationary Earth Orbit, due to the risk of high energy collisions with valuable spacecraft.
Orbital debris comprise the non-functional hardware orbiting the Earth, decommissioned spacecraft, spent upper stages, operational debris or residues from collisions; 94% of catalogued orbital objects are nowadays orbital debris. A complete presentation of the topic has been published with the year 2000 revision of the IAA Position Paper on Orbital Debris.
