An active debris removal parametric study for LEO environment remediation
Recent analyses on the instability of the orbital debris population in the low Earth orbit (LEO) region and the collision between Iridium 33 and Cosmos 2251 have reignited interest in using activeExpand

Origins of Solar System Dust beyond Jupiter
The measurements of cosmic interplanetary dust by the instruments on board the Pioneer 10 and 11 spacecraft contain the dynamical signature of dust generated by Edgeworth-Kuiper belt objects, as wellExpand

A sensitivity study of the effectiveness of active debris removal in LEO
Abstract The near-Earth orbital debris population will continue to increase in the future due to ongoing space activities, on-orbit explosions, and accidental collisions among resident space objects.Expand

Controlling the growth of future LEO debris populations with active debris removal
Abstract Active debris removal (ADR) was suggested as a potential means to remediate the low Earth orbit (LEO) debris environment as early as the 1980s. The reasons ADR has not become practical areExpand

Collision activities in the future orbital debris environment
Abstract We have analyzed potential collision activities among orbiting objects for the next 100 years from the low Earth orbit (LEO), medium Earth orbit (MEO), to geosynchronous orbit (GEO) regions.Expand
