The purpose of this thesis is to describe the DART mission to the Didymos binary asteroid system. To do this we start with a general description of asteroids and then move on to binary systems, important scientific targets for studying the formation and evolution of asteroids and shedding light on the evolutionary aspects of the Solar System itself. The discussion will then shift to the modalities and purposes of the DART mission, the first mission with the goal of testing a planetary defense system against potentially dangerous bodies. The system of (65803) Didymos, the target of the DART and Hera missions, will be discussed, discussing its dynamical, morphological and spectroscopic characteristics. Finally, the first results produced by the observational campaigns, terrestrial and space-based, that began immediately after the probe's impact with the asteroid Dimorphos will be described.
Lo scopo di questa tesi è quello di descrivere la missione DART al sistema asteroidale binario Didymos. Per fare questo si parte da una descrizione generale degli asteroidi per poi passare ai sistemi binari, importanti obiettivi scientifici per studiare la formazione e l’evoluzione degli asteroidi e far luce sugli aspetti evolutivi del Sistema Solare stesso. La trattazione si sposterà poi sulle modalità e le finalità della missione DART, prima missione con l’obiettivo di testare un sistema di difesa planetaria contro corpi potenzialmente pericolosi. Verrà analizzato il sistema di (65803) Didymos, obiettivo delle missioni DART e Hera, trattandone le caratteristiche dinamiche, morfologiche e spettroscopiche. Infine, verranno descritti i primi risultati prodotti dalle campagne osservative, terrestri e spaziali, iniziate subito dopo l’impatto della sonda con l’asteroide Dimorphos.

Abstract
The purpose of this thesis is to describe the DART mission to the Didymos binary asteroid system. To do this we start with a general description of asteroids and then move on to binary systems, important scientific targets for studying the formation and evolution of asteroids and shedding light on the evolutionary aspects of the Solar System itself. The discussion will then shift to the modalities and purposes of the DART mission, the first mission with the goal of testing a planetary defense system against potentially dangerous bodies. The system of (65803) Didymos, the target of the DART and Hera missions, will be discussed, discussing its dynamical, morphological and spectroscopic characteristics. Finally, the first results produced by the observational campaigns, terrestrial and space-based, that began immediately after the probe's impact with the asteroid Dimorphos will be described.File | Dimensione | Formato | |
