“…For example, Liou (2011), Loftus et al (1993 and Lewis et al (2012) have demonstrated the positive effect of active debris mitigation on long-term debris populations. Likewise, many advancements have occurred in the detection, tracking, and characterization of artificial objects orbiting the Earth (Frü h et al, 2013;Wilkins et al, 2013;McCall, 2013;Wiegmann, 2012). Less attention, however, has focused on trajectory design and analysis to mitigate the existing debris objects, though Peterson (2012) has published preliminary results that include the identification of high-priority debris objects and a DV cost analysis for disposal missions.…”
