Nothing will ever be what the Voyager mission was,

If we had done nothing else, these findings alone would have made the Cassini mission worthwhile.

Remember, Voyager was just a flyby, Cassini is in orbit. We have the opportunity for monitoring them and their behavior, their comings and goings, how they evolve, when they appear and disappear.

While I was there, Voyager flew by Saturn. I got involved with a person who was a member of the imaging team and started working on data from Saturn, ... With all that data coming in, the imaging team didn't have enough hands or scientists to work on all of it.

Cassini is different -- it's a mission of enormous scope and is being conducted in grand style. It is much more sophisticated than Voyager, ... I can't say it's got that flavor of romance, though. Voyager was very romantic. Cassini is spectacular.

Well, in some sense we should have expected, if the recent models are correct, to see them on the dark side where the photoelectron abundance is low. So, I was surprised to see them. But once they showed up, I realized we should have expected them there all along.
