Water ice-rich patches have been detected on the surface of comet 67P Churyumov Gerasimenko by the VIRTIS (Visible InfraRed and Thermal Imaging Spectrometer) hyperspectral imager on board the Rosetta spacecraft, since the orbital insertion in late 2014 August. Among these, three icy patches have been selected, and VIRTIS data are used to analyse their properties and their temporal evolution while the comet was moving towards the Sun. We performed an extensive analysis of the spectral parameters, and we applied the Hapke radiative transfer model to retrieve the abundance and grain size of water ice, as well as the mixing modalities of water ice and dark terrains on the three selected water ice-rich areas.
