New raw images of Titan.

And this was taken from 1.5 million km. Now imagine images from 1500 km... smile.gif

WOW.....I don't remember surface features appearing as clear as that before.

There doesn't appear to be any sign of large impact craters - at least not at this resolution.

Well, that's not exactly true. This picture is sharper wink.gif :

But you're right, it is certainly the sharpest view of THIS side of Titan I have seen yet. Compare with these pictures:

and from Keck:

Anyway, I think Cassini's close approach images will be even blurrier than those of july 2nd. The only hopes I have is for very large features on the terminator. Does anyone know if closest approach is over the terminator?

I just put together a gif animation from the CB3 images. Could the bright, dark centered feature in the middle of the disc be a ray-crater? The polar activity looks interesting too...

Wow, those light areas within the dark areas sure look alot like islands!

We saw river-like featuers on the other hemisphere, maybe now we'll get oceans with real islands!

There's a very sharp boundary between the light and dark regions in that image.

Are those white features in the left part of image clouds?

They appear very similar to the clouds over the south polar region of Titan during the first (distant) flyby. My guess is that, as it is now summer on the southern Titanian hemisphere, we are seeing some substance (ethane?) subliming off the south polar 'ice' cap.

Is this the feature you were referring to as a possible impact feature? The vaguely circular structure in the first image?

I assume that you mean the very evident circular feature near the right-hand side of the image, below the dark unit. That is a diffraction ring from a dust mote in the camera optics.

No I didn't mean the dust thingy, I already edited the post. The picture now shows up as an attachment, but the pictureframe above it is still empty....hmmm.

But about the crater, remember back in july the VIMS discovered that the dark stuff was water ice and the bright stuff probably a organic goo layer? And that they doubted that the dark areas were basins?
If the feature I pointed to in my picture is truly an impact crater, the dark floor inside the bright rim should be lower right...? Could there be hope for lakes on Titan, or am I seeing 'canals'? wink.gif

Because you're trying to do an [IMG] straight to the upload folder which the sever wont allow ( with good reason )
