Orbital Debris Mitigation and Remediation 
Dr. Kerry Nock

Orbital debris is a growing concern due to the continuous and rapid accumulation of objects in space, including expended satellites, satellite or launch vehicle components, and fragments resulting from the collision between space objects. The number of significant satellite breakup events has averaged about four per year and the cataloged debris population (10 cm in size or larger) has increased at a nearly constant linear rate of 200 objects per year since the beginning of the space age.
