Uranus satellites: surface properties

Reviews the post-Voyager knowledge of the photometric, colorimetric, spectral and thermal properties of the satellites of Uranus. The Voyager observations have made it possible to determine most of the basic photometric characteristics of the satellites and to investigate albedo/color variations on their surfaces. While albedo variations of at least a factor of 2 exist, color differences (within the limited spectral range of the Voyager cameras) are almost absent (Miranda) or subdued (Oberon). There is strong evidence that albedo patterns on the satellites are related to geology, and little if any that they are correlated with charged particle dose. On some satellites (e.g., Oberon) geologically produced albedo/color patterns have been preserved for periods in excess of several Gyr. -from Authors
