Well, Helene's surface certainly appears smooth as expected:

It will be interesting to see the closeups...

Yes, but... we got a better shot of Saturn's cloudtops in return!

Yes, it is a bit disappointing, but have no fear! We get another flyby of this gal next year!

I guess this will be the highest resolution view of Helene for a while, then...

I imagine that some careful compositing, a la Tempel 1, might make for some beautiful mosaics with patches of high resolution. The varied perpectives of the lower-resolution global frames are very nice too.

Looks to me there's too much rotation to pull off a Deep Impact impactor-camera-type mosaic.

It just shows the standard we've come to expect from this mission that we're a tad disappointed with the images at closest approach. I'm sure the pointing commands for the follow-up flyby will be tweaked based on the results from this one, with even more spectacular results. Kudos to the Cassini team for the double-header flyby.

Incidentally, I wonder how difficult in comparison it will be to image Methone in a couple of years time. The flyby is a similar range, but Cassini will be travelling faster, and Methone is a tenth the size of Helene....

Have we had all the Rhea images now, and if so has anybody found signs of the possibly ring related equatorial marks?
