Has it ever happened to you when reading a book, you thought "hey, I heard that passage in a song!"?
"After a while someone asked the expriest if it were true that at one time there had been two moons in the sky and the expriest eyed the false moon above them and said that it may well have been so. But certainly the wise high God in his dismay at the proliferation of lunacy on this earth must have wetted a thumb and leaned down out of the abyss and pinched it hissing into extinction."

The longer, narrower linear feature in the previous image is suspiciously like the famous equatorial ridge of Iapetus but I can't bring myself to believe it is. The other linear object doesn't seem to be real. But the basin is real - here are some Cassini images from orbit 1. The two on the left are the same, raw and stretched. The two on the right show another big crater further west. Voyager didn't see that.
I think I will leave these moons now and move on.

This is what we get if we merge the previous set of images. The arrows indicate a circular feature, which turns out to be a giant impact basin. I wish I could say I discovered it in these images but I didn't . It showed up easily in Cassini images and with hindsight it could be seen - just - in this Voyager image. The arrows show two other possible features. Bits of them show up in individual frames. They might be real but are not obvious in Cassini images. #Saturn #Voyager #Iapetus.

The previous post was a single image, but the next Voyager 1 Iapetus sequence was multispectral, and 5 of the frames were useful. Here they are (the numbers are image IDs). Look at the one on the left - the dark area contains some great details, little loops and lines. But they are not in the other images, they are artifacts of the noise, random groups of brighter pixels). But if we merge these images the noise is subdued and any real details stand out more clearly. #Saturn #Voyager #Iapetus

Cassini surmised, correctly, that Iapetus had a dark side and a bright side, and could be seen easily only when the bright side was facing the observer. As the visibility was always good on the same side of the planet he concluded Iapetus was in synchronous rotation like our Moon.
Here is one of the Voyager 1 images of the area I want to examine. Not much to see... that dark ring is presumably a crater but we don't see it very clearly. But we will see more... #Saturn #Voyager #iapetus

I am now turning to Iapetus, a moon of Saturn which was not well seen by Voyager. Let's start with a map from the USGS based on the Voyager images of Iapetus. The most prominent thing is the vast black area now called Cassini Regio. J. D. Cassini discovered the moon in 1671 but he could only see it when on one side of Saturn. Later with a better telescope he could see it faintly on the other side of the planet. What's going on? #Saturn #Voyager #Iapetus

Droneybird explorations around the Southern Uplands Fault.
Years ago I used to drive the A77 through Ayrshire and just knew there was _something_ interesting about the landscape. Only recently have I learned that the collision and subduction associated with the Iapetus Ocean's closure during the Caledonian Orogeny (~420Mya) caused the emplacement of the Ballantrae Ophiolite Complex.

Thanks to its distant, inclined orbit, Iapetus is the only large moon from which you could get a good view of Saturn's rings.

@kevinmgill And that crater on #Iapetus makes it look like the #DeathStar hahaha. Resisting the urge to lead with that fact must have taken you superhuman supescience strength, mate. 🤪

So Saturn has this moon Iapetus. Besides being a really fun word to say, this moon is pretty cool. And not only because it's made primarily out of ice. It has a striking appearance with the leading hemisphere taking a reddish-brownish coloring; the rest is icy white.
But it gets better... Iapetus has this weird equatorial ridge, 1,300km long and up to 13km high. No idea how they got there!
