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.

We'll you'll either have to quit your job or just wait till you get home to look at that stuff then!

Thanks for the links, Paul. Looking forward to the flyby!

Images from the Dione flyby are starting to show up even though some of the image links at the Cassini website are broken. 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:

The Dione images labeled "Saturn" are taken during closest approach, from a range of a few 100 km- the spacecraft was in a fixed attitude to measure particles and fields, but we were able to arrange it so the fields of view of the cameras and other remote sensing instruments were dragged across the disk of Dione during the passage. That explains why some of the NACs are blurred- the spacecraft was not tracking Dione, and we were very close.

Some nice pics of Janus and Epimetheus on this periapsis too.

Yes, Bjorn pointed that out.

Is it an icy cliff? Or the wall of a crater?

"Is it an icy cliff? Or the wall of a crater? "

Both. If you turn it upside down it's easier to interpret. It's an oblique view across fractured terrain and a crater.

blink.gif ...yeah, what Lyford said!

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.
