Predicted long ago to be present on the surface of planetary bodies by theoreticians and recently shown by interplanetary spacecraft and ground- based instruments to be ubiquitous in the Solar System, ices in a broad sense have become an extremely important subject in planetary research. Ices found on objects formed in the remote parts of the Solar System contain a message about the composition and mode of formation of our planetary system. There are also objects that contain icy materials that bear signatures of past events on a geological timescale. Their study is one of the best...
