Recent article in Science by Zebker et al.:
Zebker et al. Science in press, "Size and Shape of Saturn's Moon Titan". doi: 10.1126/science.1168905 (published online April 2, 2009) Link to abstract (pay-for article): http://www.sciencemag.org/cgi/content/abstract/1168905 Article on spaceref discusses this paper: http://www.spaceref.com/news/viewpr.html?pid=27912 Figure 3 from the Science article is a global elevation map relative to barycenter. Key points of article:
"Xanadu seems to be systematically lower than other parts of the equatorial belt, and not uplifted like most mountainous areas on Earth."

Nice overlay TR!
I'm not sure if the Spooky Dude formation can be discerned by RADAR. The best SAR gets is 180 m/pixel. The basins are just at the size where a pixel would splat over it. BUT, take a close look at the RADAR-dark but DISR-bright "steaming mass o' something" that is just S of where Huygens landed. That does get picked out by SAR RADAR as a small circular dark spot. (Just to the S of the green circle, 'bout halfway to the bottom of the figure.) That should be visible by VIMS (I hope!) -Mike -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/
