Mechanism for Tidal Heating on Titan

Bruce Moomaw of Spacedaily.com posted a very interesting message on the MER Forum yesterday regarding a possible mechanism for tidal heating on Titan. Bruce Bills and Francis Nimmo of Goddard Space Flight Center, UC-San Diego, and UCLA had an abstract in last years LPSC suggesting that the near 5:2 mean motion resonance between Jupiter and Saturn might be enough to maintain Titan's non-zero orbital eccentricity. This would open the door for tidal heating and subsquent cryovolcanic activity, as hinted at by RADAR and ISS data from Cassini.

Edit: I should make a correction that "Mongo" over at the MER Forum actually brought up this abstract a few weeks ago and the post by Bruce was regarding bringing that abtract up with Jonathan Lunine.
