| International guidelines recommend that objects launched in Low Earth Orbit are, at the end of their mission, either moved to an orbit of less than 25 years lifetime or, in a few special cases, maneuvered to a controlled reentry trajectory. The propellant mass needed for placing a typical 2000 kg upper stage in a 25-year lifetime orbit can be as high as 100 kg or more depending on the initial orbit and required margins. For the case in which the mission embarks, as a primary or secondary payload, an ion beam shepherd (IBS) active debris removal system one could employ the IBS spacecraft to deorbit the carrier upper stage before removing additional target debris. This would allow a considerable fuel mass savings by taking advantage of the high specific impulse of the IBS electric propulsion system for pushing the upper stage to its the target orbit. The present work discusses such possibility and performs a parametric assessment of the expected mass savings. | |
