We are very fortunate indeed.
The Voyager spacecrafts awoke our imagination then Cassini filled it with wonders beyond it!
Regarding the Ancients, we should give them the credit that they gave the name of their gods to these specks of light they saw wandering through the night skies. That is not nothing.
Thanks and Merry Christmas and Happy 2012 to the CICLOPS team and supporters!
The fountains seem suspended, like if they were not connected to the black disk of the surface. Is this the effect of Enceladus casting its shadow on the basis of the geysers?
And another question: do these jets "propel" - even slightly - Enceladus, and distort its orbit the tiniest bit? Being located in one specific spot and not compensated by other effects, on a very long period?
Or do these fractures and jets randomly migrate anyway, so their tiny effects - if any - is also randomised on the long run?
Lots of wonderful features on this image.
It has the sci-fi look with all those many worlds in one single image.
But also its small surprises and trompe-l'oeil style.
With Rhea seeming to take the place of Saturn, and with the rings looking like they are taken from the unlit side, you really need to read the explanations to decipher it correctly.
Thanks Cassini imaging team, beautiful job again.
"I think it's the same medium-sized deep crater that is in the middle of the image "Rhea 'Rev 143' Raw Preview '3" . ":
yes it is, see also the link for the Planetary Society website

There Emily Lakdawalla provides more comment on the photos, and eliminated some of the unwelcomed features in raw images.
Do you plan to produce color images of the same region?
Or do you need this special filter to produce all these details, and the resulting image can be rendered in black & white only?
A glorious image anyway, thanks for this.
It is such a desolation, isn'it? Even on the previous map, of tiny Enceladus, there is so much more variety of landscapes.
Here this is craters interspersed with a few big cracks, craters everywhere, endlessly, on thousands of kilometers. The future settlers will have to turn their gaze to the sky.
I simply LOVE these sights.
They are awesomely strange, and have such cold beauty!
I wonder how this region will look like, just 15 years from now, when it will again receive the sunlight it will be deprieved soon? All blue, I guess.
It is surely a question that has been asked a thousand times, sorry for that.
The Herschel impact crater on Mimas is always presented with much awe as the result of an event that nearly shattered this moon.
But Odysseus is even larger compared to he size of Tehtys. Is Ithaca chasma the scar of this terrible impact, or is it unrelated? If it is unrelated, then are there signs of the stressful event elsewhere?
I do agree with Red_Dragon, who posted the comment a few days ago I think: a mosaic like this makes a day.
When looking a this, a few questions pop up.
1. On top of the image, where Samarkand Sulci touches the horizon, the terrain is very rugged. Does anyone know the height of these cliffs?
2. Is it possible to extrapolate, from this height and from the resistance of the ice (I guess ice flows, even deep frozen ice like that one), a maximum age for these cliffs? The initial height is unknown, but is surely capped by gravitation. Not very precise...but might give an indication?
3. Is it possible to have a global ocean beneath the surface, and still have some old cratered terrains? By contrast, Europa is young everywhere.
4. And finally, there is often great prudence in the explanations of the forces reshaping of Enceladus. For sure, some books and articls suggest tidal forces from Saturn and Dione. But it is never as clear cut as the explanations for Io's volcanism. What's the point?
If you have ideas, I would be glad to read them.
Have a nice day all.
just to locate, I think the large crater you see on the terminator is Aeneas.
The large twins at the bottom centre are Romulus & Remus and the large crater at their bottom right (almost on the edge) is Dido.
Leading hemisphere is in the night. Trailing side on the right, in full day. If I read my map correctly...
The magnificence of these whirlpools and arabesques, magnified by the shadow cast by the low-lying Sun, is a pleasure to the eye. With the rings in the background, it is almost too perfect!
Looking at these pictures makes me understand at last why some people enjoy so much abstract paintings.
"Near lower right is the penumbral shadow of Iapetus -- the part of the moon's shadow where Iapetus does not completely block the Sun."
Shouldn't the penumbral shadow be adjacent / around the shadow?
In addition, the illumination seems to come from the lower left of the image.
Maybe the shadow on the lower right is the blocking by Rhea of the sunlight reflected by the rings.
