Part I: Introduction
Part I: Introduction “Perhaps the sentiments contained in the following pages are not yet sufficiently fashionable to procure them general favor; a long habit of not thinking a thing wrong gives it a superficial appearance of being right, and raises at first a formidable outcry in defense of custom. But the tumult soon subsides. Time makes more converts than reason.” -Thomas Paine, Common Sense (1776) “For my part, whatever anguish of spirit it may cost, I am willing to know the whole truth; to know the worst and provide for it.” -Patrick Henry (1776) “I am aware that many object to the severity of my language; but is there not cause for severity? I will be as harsh as truth. On this subject I do not wish to think, or speak, or write, with moderation. No! No! Tell a man whose house is on fire to give a moderate alarm; tell him to moderately rescue his wife from the hands of the ravisher; tell the mother to gradually extricate her babe from the fire into which it has fallen -- but urge me not to use moderation in a cause like the present. The apathy of the people is enough to make every statue leap from its pedestal, and to hasten the resurrection of the dead.” -William Lloyd Garrison, The Liberator (1831) “Gas is running low . .” -Amelia Earhart (July 2, 1937) 1 2 Dear Reader, Civilization as we know it is coming to an end soon. This is not the wacky proclamation of a doomsday cult, apocalypse bible prophecy sect, or conspiracy theory society. -

Space debris are all man made objects including fragments and elements thereof, in Earth orbit or re-entering the atmosphere, that are non functional. Obtial debris is the only man-made Space environment. The past 50 years of space exploration has unfortunately generated a lot of junk that threatens the reliability of spacecraft. The Space Debris Environment in 2010 More than 5000 satellite launches since 1957 till the end of October 2010; 245 on-orbit break-ups led to 12,500 objects in the US Space Surveillance catalog; catalog size threshold 10cm; mass on orbit 6,000 tons; catalog orbit distributions: - low Earth orbits 73%; - near-geostationary orbits 8%; - highly eccentric orbits 10%; - other orbits (incl. -
