This paper will summarize a range of techniques that have been proposed for controlling the growth of manmade debris in Earth orbit. Several techniques developed in studies at NASA Johnson Space Center will be described in detail. These techniques include the retrieval of inoperative satellites with an orbital maneuvering vehicle and self-disposal devices for satellites and upper stages. Self-disposal devices include propulsive deorbit motors and passive drag-augmentation devices. Concepts for sweeping small debris from the orbital environment will also be described. An evaluation of the technical feasibility and economic practicality of the various control methods will be summarized. In general, methods that prevent the accumulation of large debris objects were found to provide greater promise for control of the debris problem than methods of removing small debris particles.
