NASA Double Asteroid Redirection Test (DART) mission [1] impacted the surface of Dimorphos, the secondary asteroid of Didymos binary system on 26 September 2022. The Light Italian Cubesat for Imaging of Asteroids (LICIACube) [2], provided by the Italian Space Agency (ASI) was released 15 days before the impact to acquire high-resolution images of its effects. During the LICIACube flyby of Dimorphos (minimum distance of 57.78 km), LEIA and LUKE the two cameras on board the cubesat acquired more than 400 images. LUKE (LICIACube Unit Key Explorer) is a wide-field camera (5°x10° field-of-view), with an RGB Bayer pattern filter to acquire simultaneously color data to recompose the three final 24-bit colour images. Its main aim was to study the colours of surfaces and plume and acquire information about the plume evolution [3]. Color analyses are fundamental to investigate the physical properties of the plume, such as the grain size [4] or the degree of alteration of the surface from space weathering of Dimorphos.

Abstract
NASA Double Asteroid Redirection Test (DART) mission [1] impacted the surface of Dimorphos, the secondary asteroid of Didymos binary system on 26 September 2022. The Light Italian Cubesat for Imaging of Asteroids (LICIACube) [2], provided by the Italian Space Agency (ASI) was released 15 days before the impact to acquire high-resolution images of its effects. During the LICIACube flyby of Dimorphos (minimum distance of 57.78 km), LEIA and LUKE the two cameras on board the cubesat acquired more than 400 images. LUKE (LICIACube Unit Key Explorer) is a wide-field camera (5°x10° field-of-view), with an RGB Bayer pattern filter to acquire simultaneously color data to recompose the three final 24-bit colour images. Its main aim was to study the colours of surfaces and plume and acquire information about the plume evolution [3]. Color analyses are fundamental to investigate the physical properties of the plume, such as the grain size [4] or the degree of alteration of the surface from space weathering of Dimorphos.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
