Low Earth orbit (LEO) is experiencing a renaissance thanks to increasing commercialisation of space. The opportunities provided by small satellites are enabling diminutive companies and startups, in particular, to make a significant impact on the space economy. Small satellites have played a vital role in this revolution and they have a unique ability to bring around new products and services at short timescales and for relatively low-cost.

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.
