Wow. These tiny moons never fail to bewilder.

... that's a pretty astonishing little body. The solar system seems to have an endless supply of surprises. I guess this is the face that launched a thousand [space]ships. Or a thousand excited exclamations of a word that sounds like ship. |

RGB composites, one in natural-ish contrast and another contrast-enhanced:
The illuminated hemisphere seems to be the same one as the saturnshine-lit one in this image. I think this is my favorite of the small Saturnian rocks. -------------------- |

I'm posting a link to my Helene 'mini-atlas' for reference:

Wow. Yet another object in the Saturn system that qualifies as one of the strangest ones I've ever seen. Maybe it's becoming necessary to redefine what strange means in this context because the 'stereotype' small and irregular asteroids/moons with nothing but craters seem to be really rare.
I get the impression that we may be looking at erosion features but I'm not sure how something like that might work. Congratulations to the Cassini team for perfect pointing this time. |

Excellent images! Ski slopes on the Saturn's moon!
 Surface of Helene is really extraordinary and it looks, that it is very young. -------------------- |

It looks as if a surface crust is eroding away... very odd.

QUOTE (Ian R @ Jun 20 2011, 11:12 AM)  Here's a 'bouncy' flyby movie: Wow. When the thin crescent slowly reveals itself to be an object coming out of the gloom....wow. That is beautiful. -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/

Great work Ian. I know how time consuming that can be.
Is that series cycling through images taken with different filters? -------------------- If Occam had heard my theory, things would be very different now.
