Misconceptions and Reality of Orbital Debris Risk

Since the formal commissioning of the NASA Orbital Debris Program Office in the 1970s, the risks of orbital debris have gradually become more widely known to the community of space experts. The subject has even entered the mainstream of popular culture (e.g., the 2013 film “Gravity”). Growth in professional and public interest has been mirrored by a growth in misconceptions concerning the nature and scope of orbital debris risks and how to “fix the problem.” This is a global issue, both complicated and potentially expensive, so it is important that problem solvers and policy makers ask the correct questions and address the right problems. This paper will identify and clarify a select number of these misconceptions and highlight the best cost-effective solutions.
