Abstract
ear-Earth objects (NEOs), due to their proximity to our planet, represent one of the most accessible bodies in the whole Solar System. Their investigation, other than providing vital information to planetary formation and water delivery, is compelling due to the hazard these bodies pose to human civilization. The DART/LICIACube mission: To this purpose, the NASA Double Asteroid Redirection Test (DART) has been approved to be the first demonstration of kinetic impactor as an asteroid hazard mitigation [1]. The DART spacecraft successfully crashed onto the secondary member of the Didymos system (Dimorphos) on September 26th 2022 at 23:14 UTC. Hosted as a piggyback and released fifteen days before the DART impact there was also the Light Italian Cubesat for Imaging of Asteroids (LICIACube, 2), a 6U cubesat space mission financed by the Italian Space Agency (ASI). LICIACube with its two scientific cameras (LUKE & LEIA) has testified the impact and characterized the system and the ejecta plume in the aftermath of DART event with an incredible level of detail. In addition, the ESA Hera mission, to be launched in 2024, will continue the characterization of the binary system.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
