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.
