Re: Cassini Equinox Mission (Cassini's two year extension).
You are very welcome abq_farside. Pleased you like them & hope you find them interesting.

Something we have not had for a while, a Cassini Synthetic Aperture Radar Image of Titan.
The Titan Radar Mapper acquired this image at 41 North, 213 West, Belet Regio, on Monday 28th December 2009. The image measures 285 KM by 250 KM, with resolution of about 350 meters. North is up & the image is illuminated from the right. The grooved hills are approx 60 metres high.
These hills bear a resemblance to the 'Spider' formations, discovered by the Magellan Venus Orbiter on Venus, where as Venus has a volcanic basaltic rocky surface at a temp of approx plus 450 C / 723 K, Titan's hills are icy at a temp of approx minus 180 C / 93 K. Perhaps these hills are a result of cryovolcanism?????
Grooves in hills. I have rotated the image so north is at top. The original has north at left.

An enlarged sharpened crop I did of the groove cut hilly terrain in the SW (lower left) portion of the first image. The area cropped is approx 80 KM wide. The grooves do look more like channels in the crop.
