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

Nothing will ever be what the Voyager mission was,

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.

There's nothing ambiguous about the findings.

It's been a very worthwhile experience, ... There hasn't been a day when I've felt this was a mission we shouldn't be involved with.

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.
