When you look at the evolution of thermal models starting from 20 years ago, when I entered the field, we were assuming that these bodies were pure water ice and rock. But then we realized that the materials that make up these moons can be very complex, and some of them can be insulating. There can be a lot of porosity, and maybe the water has impurities like ammonia and salts. All this contributes to maintaining and preserving oceans in these objects.
