From Wikipedia: MONITORING OF SPACE DEBRIS The U.S. Strategic Command maintains a catalogue currently containing about 13,000 objects, in part to prevent misinterpretation as hostile missiles. Observation data gathered by a number of ground based radar facilities and telescopes as well as by a space based telescope is used to maintain this catalogue. Nevertheless, the majority of debris objects remain unobserved. There are more than 600,000 objects larger than 1 cm in orbit (according to the ESA Meteoroid and Space Debris Terrestrial Environment Reference, the MASTER-2005 model). Other sources of knowledge on the actual space debris environment include measurement campaigns by the ESA Space Debris Telescope, TIRA, Goldstone radar, Haystack radar, and the Cobra Dane phased array radar. MITIGATION MEASURES In order to mitigate the generation of additional space debris, a number of measures have been proposed: The passivation of spent up
