Le attività spaziali in quasi tutti i regimi orbitali sono ora a rischio a causa della continua crescita della popolazione dei detriti spaziali. Per prevenire la proliferazione dei detriti spaziali in orbita terrestre è necessario affrontare il problema da prospettive diverse, sfruttando le più avanzate conoscenze teoriche e sperimentali in campi diversi come l'astrodinamica, l'ingegneria aerospaziale e la giurisprudenza spaziale. Questo approccio permette di affrontare quattro pilastri principali: prevenzione, protezione, mitigazione e regolamentazione. A tale riguardo, la Comunità europea ha finanziato un progetto H2020 chiamato ReDSHIFT il cui obiettivo è trovare metodi passivi (ovvero che non richiedano uso di propellente aggiuntivo e l'intervento di veicoli spaziali ad hoc) per mitigare la proliferazione dei detriti spaziali.

Abstract
The space activities in almost every orbital regime are now jeopardized by the continuous growth of the space debris populations. To prevent the proliferation of the space debris in Earth orbit it is necessary to tackle the problem from different perspectives, exploiting the latest theoretical and experimental knowledge in different fields, such as astrodynamics, spacecraft engineering and legal studies, to address four main pillars: prevention, protection, mitigation and regulation. In this respect the European Community financed a large H2020 project named ReDSHIFT whose goal is to find passive means to mitigate the proliferation of space debris. A short summary of the project and of its main findings is given in the paper, with particular emphasis on the more theoretical part, related to the simulation of long term evolutionary scenarios of the whole space debris environment and to the mapping of the Low Earth Orbit phase space, looking for passive dynamical de-orbiting solutions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
