Abstract
The ReDSHIFT H2020 European project has shown, among other findings, that passive disposal procedures can benefit from the exploitation of dynamical perturbations. In particular for the Low Earth Orbit (LEO) region, a natural eccentricity growth can be leveraged in order to reenter to the Earth's atmosphere at a lower Dv-budget. The numerical cartography of the region has been proven from a theoretical perspective, on the basis of a frequency analysis focused on solar radiation pressure and lunisolar perturbations and on dynamical systems theory tools. In this work, we summarize the whole study concerning the dynamics that characterizes the LEO region in the long-term, by giving a comprehensive picture of the theoretical findings together with their possible exploitation for the debris mitigation. Moreover, with a specific long-term modelling of the future launch traffic, we will show how the de-orbiting corridors represent concretely an opportunity to enhance the end-of-life de-orbiting and limit the population growth, in particular for high-altitude spacecraft.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
