Libration Point Orbits (LPO) and Highly Elliptical Orbits (HEO) are often selected for astrophysics and solar terrestrial missions as they offer vantage points for the observation of the Earth, the Sun and the Universe. No guidelines currently exist for LPO and HEO missions' end-of-life; however, as current and future missions are planned to be placed on these orbits, it is a critical aspect to define a sustainable strategy for their disposal, with the objective to avoid interference with protected regions.

The awareness of the risk of uncontrolled accumulation of man-‐made objects became significant in the late 70's and since then, a number of space debris mitigation guidelines have been published by various organizations. The general aim is to reduce the growth of space debris by ensuring that space systems are designed, operated, and disposed in a manner that prevents them from generating debris throughout their lifetime, assuring the sustainable space utilization.
