This work investigates end of life disposal options for libration point orbit missions. Three different options are presented: the first one considers spacecraft’s re-entry in Earth’s atmosphere, the second one concerns the impact on the Moon, whereas the third one consists in the injection of the spacecraft into a heliocentric graveyard orbit. The disposal design is formulated as a multi-objective optimization problem in order to take into account other goals in addition to propellant consumption minimization. The disposal of Gaia mission is used as test case throughout the paper.

Abstract

This work investigates end of life disposal options for libration point orbit missions. Three different options are presented: the first one considers spacecraft’s re-entry in Earth’s atmosphere, the second one concerns the impact on the Moon, whereas the third one consists in the injection of the spacecraft into a heliocentric graveyard orbit. The disposal design is formulated as a multi-objective optimization problem in order to take into account other goals in addition to propellant consumption minimization. The disposal of Gaia mission is used as test case throughout the paper.
