Active removal of large massive objects by hybrid propulsion module. In: EUCASS 2013 - 5th European Conference for Aero-Space Sciences (Munich, Germany, 1-5 July 2013). Proceedings, article n. 469.

This paper deals with the feasibility study of a mission for the active removal of a large massive object, such as the second stage of the Zenit launcher or the Envisat spacecraft, abandoned in the most populated orbit region in low Earth orbit. Critical mission aspects and related technologies are investigated at a preliminary level. In particular, an innovative electro-adhesive system for target capture, mechanical systems for chaser-debris hard docking and a hybrid propulsion module for rendezvous and controlled de-orbiting and reentry are analyzed. A preliminary mass budget for the needed chaser platform and hybrid propulsion module is also performed, showing that the chaser spacecraft overall mass varies in the range 1500-1700 kg, with the propulsion module weighting about 900 kg.
