T42 Mission description now up.

http://saturn.jpl.nasa.gov/multimedia/prod...description.pdf

Imaging highlights:

• Last of the S hemisphere flyover sequence.
• Long VIMS stretch in "noodle mode" going into northern territory. ("noodle mode" gives a longer track, but is less accessible for us sitting in the cheap seats.)
• A VIMS "sit and stare" section
• ISS imaging of the area in N Belet and polar regions. (Hopefully a good look at the Dancing Monkey feature)

Well, let's just say there is disagreement about those. There are bright streaks in that area. The VIMS data suggest they are mountains based on apparent shading that seems consistent with them being topographic highs. However, ISS also sees many of these supposed shadows (ISS doesn't see topographic shading on Titan due to the higher atmospheric scattering at 938 nm, the wavelength ISS uses to see the surface) and see many bright and dark features in the region (that may look like shading at VIMS' lower resolution).

A few possible alternatives are that these are fresh fractures on Titan surface, with cleaner water ice/ammonia hydrates (akin to the fractures on Dione and Rhea) or these maybe fissures where such material has been extruded from the interior.
