A RAS Specialist Discussion Meeting organised by *Kathryn Harriss and Mark Burchell (Kent)*Contact: k.harriss@kent.ac.uk Water ice is a dominant material within the solar system, theorised to make up 50% of the mass of material beyond the solar system frost line. This leads to ice landscapes, features and bodies being studied using a number of techniques on number of differing planetary bodies. Recent explorations have shown more ice regions and landscapes on Pluto, Ceres and comet 67-P that have ignited many fields of planetary sciences to focus on the icy bodies from landscapes and internal structures to impact studies to cyrovolcanism to degassing of asteroids and comets and the implications for astrobiology. The aim of this discussion meeting to discuss the latest research into the surface of icy bodies and regions in the solar system. We invite all whose work include the investigations of ices including weathering, astrobiology, landscapes and surfaces of different planetary bodies. We welcome research from all aspects of research including computational modelling, laboratory and field work.  10:30 Kathryn Harriss University of Kent
