Mineralogical analysis and preliminary physical property results on Didymos/Dimorphos meteorite analogues

Meteorites, together with return mission samples, represent unique tools to investigate Solar System bodies. Unfortunately, planetary surface sampling is rarely possible and the attribution of a meteorite to a planetary body is tentatively done using reflectance spectroscopy techniques. Double asteroid 65803 Didymos/ Dimorphos, supposed to be formed by stony material chemically affine to L/LL ordinary chondrites, was the object of the DART (Double Asteroid Redirection Test) mission (Michel et al., 2018), and it is planned to be visited by the next HERA mission, to investigate the subsurface and interior properties of impact site outcome materials exposed by the kinetic DART impactor.
