On 26 September 2022, the Double Asteroid Redirection Test (DART) spacecraft impacted the surface of Dimorphos, the ~150 m-size moonlet of the binary system (65803) Didymos (~780 m-size, ), allowing detailed surface characterization. Both DART and the Light Italian Cubesat for Imaging of Asteroids (LICIACube, ) provided direct observations of geological features, including lineaments, rocks' fractures and/or cracks, boulders, craters and signs of mass movements. Here we study both boulders' fractures and mass movements in order to constrain their formation processes and to investigate the formation and evolution of the Didymos system. Specifically, boulders cracks analysis is pivotal to constrain the internal structure and history of the body and the occurrence of mass movements provide crucial insights on the mechanical behavior of the binary system's constitutive material.

Abstract
On 26 September 2022, the Double Asteroid Redirection Test (DART) spacecraft impacted the surface of Dimorphos, the ~150 m-size moonlet of the binary system (65803) Didymos (~780 m-size, ), allowing detailed surface characterization. Both DART and the Light Italian Cubesat for Imaging of Asteroids (LICIACube, ) provided direct observations of geological features, including lineaments, rocks' fractures and/or cracks, boulders, craters and signs of mass movements. Here we study both boulders' fractures and mass movements in order to constrain their formation processes and to investigate the formation and evolution of the Didymos system. Specifically, boulders cracks analysis is pivotal to constrain the internal structure and history of the body and the occurrence of mass movements provide crucial insights on the mechanical behavior of the binary system's constitutive material.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
