"Space junk crashing into Earth is a real and escalating danger. Tens of millions of objects may exist in space, ranging in size from grains of sand to entire rocket boosters.".

"Milne provides the first synthesis of the interdisciplinary work of the scientific community, which has been investigating how the satellite industry can be protected from manmade and natural space hazards. The result is an invaluable book for those concerned with space missions and space disasters, those worried about cosmic radiation and its effects on humans, members of the Spaceguard defense movement, and anyone concerned with defense and international cooperation efforts in general."--BOOK JACKET.
