| Abstract: | The observational evidence given by Galileo spacecraft about Europa supports an icy rigid layer of several kilometers over
another ductile layer of ice in convection, which floats over an internal ocean of liquid water. Before the onset of convection,
heat is transmitted into the crust by conduction. The heat flow analysis in the potentially convective layer gives values
higher than those obtained previously by tidal dissipation models, and suggests that the ice may be limited to a thin layer
of ∼4 km total thickness.
