  Lainey et al. (2012), by re-analyzing long-baseline astrometry of Saturn's
moons, have found that the moons' tidal evolution is much faster than
previously thought, implying an order of magnitude stronger tidal dissipation
within Saturn. This result is controversial and implies recent formation of at
least some of the mid-sized icy moons of Saturn. Here we show that this more
intensive tidal dissipation is in full agreement with the evolved state of the
Titan-Hyperion resonance. This resonance was previously thought to be non-tidal
in origin, as the amount of tidal evolution required for its assembly is beyond
what is possible in models that assume that all the major moons are primordial.
We find that the survival of the Titan-Hyperion resonance is in agreement with
a past Titan-Iapetus 5:1 resonance, but not with unbroken tidal evolution of
Rhea from the rings to its current distance.
