Ice shell research focuses on understanding the structure, composition, dynamics, and evolution of icy outer layers on celestial bodies such as moons and planets. This includes studying the thickness, temperature, and properties of ice shells, as well as their interactions with underlying oceans or rocky interiors. Ice shell research is important for understanding the potential for habitability on icy moons like Europa and Enceladus, as well as for investigating processes such as cryovolcanism and tectonics on icy bodies in our solar system and beyond.
