Nice mosaic of the new territory on the ciclops page. There are some prominent features running to the north, fractures or wide river valleys?

There are some interesting long narrow dark features showing in the top half of some of these images, towards the terminator. For example:
http://saturn.jpl.nasa.gov/multimedia/imag...8/N00080113.jpg Anyone know which part of the globe that is? It must be north-ish. Edit: Ah yes, I see where we are now on the Ciclops mosaic. Hope we can see more detail of these when processed. They look way too big to be drainage channels and there are few if any branchings. |

Here's a composition with the raw images.
I don't know if this is correct, maybe I'm missing some images, but it's a first try...

Noting the way that both the two on the left could be seen as wrapping around circular-ish patches, I wonder if these are tectonically created features associated with a group of large impacts. IIRC the impact/tectonism link has been invoked elsewhere on Titan.

What's this, anybody?
http://saturn.jpl.nasa.gov/multimedia/imag...8/W00026729.jpg Edit - add caption: W00026728.jpg was taken on March 26, 2007 and received on Earth March 27, 2007. The camera was pointing toward TITAN at approximately 208,188 kilometers away, and the image was taken using the CL1 and CL2 filters. This image has not been validated or calibrated. A validated/calibrated image will be archived with the NASA Planetary Data System in 2008. |

QUOTE (ugordan @ Mar 28 2007, 01:59 PM) Stray light. Yes, that would make sense for the 'paintbrush' feature. There is also some overall shading with an elliptical shape around the moon - stray also? What do you think they were looking for/pointing at? |

QUOTE (ngunn @ Mar 28 2007, 03:11 PM) What do you think they were looking for/pointing at? Hard to say really. Judging by the 4x4 binning and pointing I'd say it was just a few ridealong snaps while UVIS was controlling the pointing. To help constrain pointing knowledge better, I guess.

I see, thanks. Maybe the long exposure was to look for very high atmosphere features if present.

Those long stripes in the north were seen on the first view of this area a few weeks earlier (but not noted at the time) , and a processed mosaic was shown at LPSC. I can't offer an interpretation, but it certainly shows that Titan has significant regional variations from place to place.

Does anyone have a link to that mosaic other than the colorised and wrapped-around-the-sphere version linked in post 2 above? Phil, if it was presented in conference was it published somewhere as 'supporting material' or whatever? These lines certainly look like something new and it would be nice to have the best possible view available for discussion here.
