The concept of using Active Debris Removal (ADR) to reduce the space debris population has been stated in numerous studies, reports, and policies. Finding what method is most effective, realistic, and sustainable are important factors in the future use of ADR. This paper discusses the potential technology, various mitigation methods, and other options of dealing with space debris in Low Earth Orbit (LEO). The paper uses a graphical model to view the ideal effectiveness of various options and provides recommendations based on these findings. The recommendations are to focus efforts on robotic arms, nets, active reentry plans, and removal policies. To have LEO’s environment avoid overpopulation, multiple forms of ADR and mitigation strategies must be used at this time.
