The ESLAB 50 Symposium - spacecraft at comets from 1P/Halley to 67P/Churyumov-GerasimenkoInternational audienceDeep Impact, EPOXI and Rosetta missions visited comets 9P/Tempel 1, 103P/Hartley 2 and 67P/Churyumov-Gerasimenko respectively. Each of these three missions was equipped with both multispectral imagers and infrared spectrometers. Bright blue features containing water ice were detected in each of these comet nuclei. We analysed multispectral properties of enriched water ice features observed via OSIRIS NAC on comet 67P in the wavelength range of 260 nm to 1000 nm and then compared with multispectral data of water ice deposits observed on comets 9P and 103P. We characterize the UV/VIS properties of water ice rich features observed on the nuclei of these three comets. When compared to the average surface of each comet, our analysis shows that the water ice deposits seen on comet 9P are similar to the clustered water ice rich features seen on comet 67P, while the water ice deposit seen on comet 103P is more akin to two large isolated water ice rich features seen on comet 67P. Our results indicate that the water ice deposit observed on comet 103P contains more water ice than the water ice rich features observed on comets 9P and 67P, proportionally to the average surface of each nucleus
