Global view, color balanced according to this calibrated view which shows almost the same view.

The equatorial dark stains are faintly visible above. Here's a narrow-angle segment of the equatorial markings centered around the two craters near image center above, contrast-enhanced IR3/GRN/UV3 color:

Thanks for yet more wonders, Mike & Gordan. (Still overloaded, here!)

I never knew about Rhea's 'lineaments'; what the deuce? Are they analogous to Ganymedian "racetrack" features, albeit at a smaller scale? They're oddly straight.

Putting Gordan's [IR3,GRN,UV3] image with the the lineament feature [RED,GRN,BL1] image above you get a nice mosaic of the equatorial stains:

There are two other threads that cover this information extensively Link Link

ugordan is the acknowledged discover of the equatorial markings on Rhea for which he received the prestigious award from UMSF Link

A couple of Rhea cross-eye stereo views:

Ah--How did I forget that? Thanks, Floyd, and apologies, Gordan!

Was just rather taken aback by the appearance of the lineaments in Mike's image; they look like scratches on a dirty crystal ball!

Yep, the rhea equatorial deposits were also discovered independently by two other teams, including myself. Its really only a matter of time before these things are found out. Ive been doing some high res mapping and am working on some new products showing these things in much better detail. It was the subject of my DPS presentation in october as well, and are the subject of a recent blog on stereomoons.blogspot.com. the alignment indicates they are fallout from Rhea's ring onto the surface. cool huh? stay tuned!

I've had a question right from almost the start of this thread, the same one I think that appears in post 2. The question was "What are the lineaments?" I thought I'd wait until the answer turned up but it hasn't. All the subsequent discussion has been about the equatorial dark marks - a great subject, I agree. I'm a big fan of rings around moons.

But what are the other lineaments in that image, the thin bright lines at many angles? Rays from impact craters? Scarps? They are very narrow but have an observable finite width in places.

Like the similar lines radiating from 'Cassandra' in the southern hemisphere of Dione, they are probably straight, narrow fractures exposing fresh ice along the faults. These on Rhea were already seen in Voyager images.

Hello all...I've clearly missed a lot recently! Incredible stuff.

Better late to the party than never, so here's a mosaic of the tectonized terrain crudely reprojected to the perspective shown in W00061506. I've left out the two disconnected southern frames and the stereo images.

Stunning amount of detail! Great work! Thank-you!

Raw images from REV 121 of Titan and Rhea together taken on Nov 19th 2009 featured recently as Cassini browse image ‘Biggest Saturnian Moons’ http://photojournal.jpl.nasa.gov/catalog/PIA12724 provide a natural spectacle and opportunity for us fortunate photoshop users to work with.
Below shows the RGB of Titan. Motion occurred between shots so a cut and paste of Rhea from the browse image
was used. 3D image is one of those eye-crossers again!

And coincidentally, just a few days before the real raw data for that hits PDS...

Of curiosity, what is providing the backdrop for that image? I can make out the night side limb of both Rhea and Titan.

Artistic license! While a more exotic, natural source such as 'Saturnshine' might be considered the truth is this is an artifact achieved by the brightening of raw image N00146489 taken with the BL1 CL2 filter, after it was blue photo-filtered in Photoshop. This was done purposefully to bring out the detached haze layer and yes the unilluminated portions of Titan. Rhea's dark side was selected with the magic wand and brightened a bit. You have a keen eye!

been busy processing latest batch of moon releases on pds and took a screen shot of this registered and calibrated mosaic of the equator of Rhea, showing the equatorial stripe. our paper describing the origin of this and the broad band of Mimas are now online at Icarus "Plasma, plumes and Rings...." (ill haven=more on that later- i just arrived in pasadena for DPS and getting bearings...).

weeeee! moons are fun!

Something that we have not seen before. Rhea seen by radar.

Very interesting, thanks for posting. Check out that radar-bright spot on the right.

Would it be overly cheesy to call it Rheadar?

Yes, positively Gorgonzolian!
