T47 Mission description available here!

VIMS noodling near Huygens Landing Site
CIRS looking at nitrile and hydrocarbon concentrations near the Equatorial limb
UVIS looking at aerosol concentrations in upper atmosphere (particulate data) from 2 (two) stellar occultations

And ISS will get some nice images of Hotei Arcus, E Xanadu, and W Fensal region (looks like Sotra Facula will be in the dark).

Here is a zoom of the completed T47 SE Xanadu - Hotei Arcus Mosaic with the T13 RADAR Swath blended in:


(For the RADAR Swath, this is approximately 1.4 km/pixel resolution)
The dark lane at the top of the T13 Swath correlates to a slightly-darker-than-surrounding lane in the T47 ISS images.

The more I stare at this, the more I really, really like the flood cryobasalt idea:

The darker arc shape to the NE of Hotei Arcus is dark in both the ISS and RADAR. But as you work your way up the arc shape counterclockwise into the T13 Swath area, the dark zone yields to lighter toned terrain with a continuing arc shape pattern. This would imply that the lower reaches are embayed and the upper lighter tone terrain is not, suggesting topographic control. (The regional gradient is to the S, as evidenced by the bright channels).

It seems likely that some of the darker spots closer to Hotei Arcus are similar embayed lowlands similar those seen in the T13 Swath.
(It is not clear if RADAR-dark always correlates to ISS dark in Xanadu.) (Note how jagged RADAR-bright streams cross the embaying material.)
