I . A . M o t i v a t i o n : O r b i t a l D e b r i s i n L E O Currently, the US Space Command tracks roughly 6,000 objects in LEO. Less than 300 of these objects are operational spacecraft. The rest are spent rockets and derelict spacecraft. 3 In addition, there are countless numbers of debris objects too small to be tracked; these objects result from explosions of rocket stages and fragmentation of spacecraft. These objects pose a growing risk to operational spacecraft. Moreover, in t h e

These satellites will have operational lifetimes of approximately 5-10 years. Unless proper measures are taken to remove these satellites from orbit at the end of their lives, the debris population in LEO may grow exponentially, making many orbital slots useless.
