Abstract: The growing awareness of the space debris problem has motivated the scientific community to look for effective and feasible active and passive end-of-life disposal solutions for spacecraft orbiting the Earth, in particular the Low Earth Orbit (LEO) region. It is now recognized the idea that the mission design must comprise end-of-life strategies to preserve the space environment and for the sustainability of the whole program. To this end and to make it affordable, it is mandatory to achieve a deep understanding of the dynamics pervading the circumterrestrial space. Starting from an explanatory introduction on the problem and on the worlwide effort, the talk will address the recent advancements obtained in the framework of the ReDSHIFT H2020 project concerning the dynamical mapping of the LEO region, by means of extensive numerical simulations and analytical studies of the resonances due to solar radiation pressure and third-body perturbations.
