   I think it was Harlow that wanted more from me. Some hold me to a
   higher standard that others, so I'll try to accommodate. Understanding
   something about tidal forces providing the energy to keep water melted
   is suspected in many outer moons. It is interesting to watch over the
   weeks and years how the mechanisms are deduced from observations. This
   is exciting, as we are witnessing the process of science in real time.
