Active debris removal and space debris mitigation using hybrid propulsion solutions

Abstract

This paper presents the results of a study carried out in the frame of the ESA General Studies Programme (GSP), dealing with the feasibility of performing active debris removal by using a hybrid propulsion system embarked on the chaser spacecraft. While the study focuses mainly on the use of a hybrid rocket propulsion system on-board a chaser spacecraft that performs active debris removal, it also addresses the application of this innovative propulsion technology for debris mitigation purposes. Hybrid propulsion systems seem to be a promising alternative to conventional liquid propellant in-orbit propulsion systems, in terms of complexity, cost, operational advantages, whilst also offering the use of non-toxic propellants. The study has been carried out by Elecnor Deimos, expert in mission analysis, and Nammo Raufoss, expert in hybrid propulsion.
