Cassini's second hyperclose pass of Dione is just days away. Ive posted some new views and thoughts about Dione
on FB and YT (links below) of some of the features that might be visible in the images, which will show mostly the leading
hemisphere. Jeff Moore and I have been working on a volcanic hypothesis for the smooth plains and the odd features found within
it, which we hope to submit for publication very soon.

Thanks for the links, Paul. Looking forward to the flyby! -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

Some semi-random examples: http://saturn.jpl.nasa.gov/photos/raw/rawi...?imageID=215456 http://saturn.jpl.nasa.gov/photos/raw/rawi...?imageID=215471 http://saturn.jpl.nasa.gov/photos/raw/rawi...?imageID=215449 Interesting fractures and linear features - I doubt the horizontal lines are real but don't have time for detailed inspection of the images now: http://saturn.jpl.nasa.gov/photos/raw/rawi...?imageID=215441 More bright fractures: http://saturn.jpl.nasa.gov/photos/raw/rawi...?imageID=215427 This is surely not Saturn as the image caption states: http://saturn.jpl.nasa.gov/photos/raw/rawi...?imageID=215391 And not this one either: http://saturn.jpl.nasa.gov/photos/raw/rawi...?imageID=215388

That explains why some of the NACs are blurred- the spacecraft was not tracking Dione, and we were very close. John

If you turn it upside down it's easier to interpret. It's an oblique view across fractured terrain and a crater. Phil -------------------- ... because the Solar System ain't gonna map itself.

This one's really giving me a 'what the hell?!' feeling like the early encounters of other moons. I don't even wanna speculate about what exactly we're looking at; need context. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
