Maybe they'll risk it whe the mission starts to wind down. A couple of
well-aimed Titan flybys can put Cassini back down close to the rings
at little cost in propellant.



The trick would be to get Cassini down near the rings and moving
parallel to them at nearly the same orbital velocity, so that the ring
particles won't pose as much of an impact threat due to their low
relative velocity.
