All the 512 x 512 frames of Dione, through the IR, GRN, and UV filters — aligned and upsized to 1,024 x 1,024.

Fantastic work guys! the Dione mosaic in colour is awesome.
There are two sub-1000km flybys of Dione this year (June and August) to look forward to, perhaps some concrete evidence of outgassing may be revealed. I'm loving Cassini being back in the ring-plane. Some distant shots of Polydeuces to come on the next revolution.. |

Some of the latest icy moons
Dione (irgrn uv):  Tethys (cl1cl2)  (ir grn uv) .... I would have rotate it, but I forgot!

What's the UMSFers take on the mysterious red streaks seen on Tethys in images from April 11th? http://www.nasa.gov/jpl/cassini/unusual-re...icy-saturn-moon
 QUOTE Like graffiti sprayed by an unknown artist, unexplained arc-shaped, reddish streaks are visible on the surface of Saturn's icy moon Tethys in new, enhanced-color images from NASA's Cassini spacecraft. The red arcs are narrow, curved lines on the moon's surface, and are among the most unusual color features on Saturn's moons to be revealed by Cassini's cameras. Images taken using clear, green, infrared and ultraviolet spectral filters were combined to create the enhanced-color views, which highlight subtle color differences across the icy moon's surface at wavelengths not visible to human eyes. Could be some kind of exposed material, but I think they might be the result of a glancing impact? -------------------- Curiosity rover panoramas: http://www.facebook.com/CuriosityRoverPanoramas

Hard to believe; they curve around the surface for hundreds of km. Plus they're all parallel, so they can't be from a single impact.

My take is "????!!!" First question for me is: endogenous or exogenous? I'd guess exo-, but how much is my guess worth?

a dense clump of outer ring material tidally disrupted and sprayed over the surface?

Ignoring the exaggerated color, they remind me of the bright fractures on Dione.

sorry the media release was so cryptic. those things tend to be short. this is rather large story and we are looking at stresses that might cause it but haven't found a clear-cut answer yet. hope to have one in a month or two. I will also blog on it when i get a chance, so to share more of the odd details . . .
