Satellites, Missiles and Debris Intentional Destruction and Unintentional Space Collisions 2007 2009, . . , 2013 ASAT Test and Space Accidents Happened
Destruction Power of Space Debris Properties of Space Debris (2010): Size: Trackable ~ 10 cm (4 in) speed: > = 10 km/s (+22,000 mph) Range: 600 to 1600 km (400 to 1000 mi) Distribution: 7% useful satellites, others junk The image above shows, the risk of damage is real. This hole over 1 cm (3/8 in) in diameter penetrates the Hubble high gain antenna dish (the unit continued working in spite of the damage). The windows on the Space Shuttles have been replaced 80 times due to impacts with objects of less than 1 mm (0.04 in). And costly systems to track and issue daily emails warning of potential impacts must be maintained.
