• The surface of Titan seems relatively smooth and uncratered, leading scientists to speculate that Titan may be geologically young.
• The moon's surface is largely devoid of any large-scale geologic features.
• There are dark areas and light areas on the surface, perhaps indicating liquid and solid areas, but measurements have shown those areas have very similar compositions.
• There are strange, streaky formations on the moon's surface as if material had been scattered by wind.
"We're seeing stuff, quite frankly, that's really hard to interpret," said Robert Brown, a UA planetary scientist who led the development of Cassini's Visual Imaging Mapping Spectrometer (VIMS), which measures chemical composition. "We're trying to hammer around and bring in information from other instruments to try and get a handle on what we're seeing. It's a little mysterious," Brown said. "The bottom line is that on other solid bodies you see things you recognize. Craters, other geologic features. This is a relatively smooth surface."

Think Death Star.
And now I have to take a break. Must drive. I should be back late Sunday. Watch for any Friday releases of bad news for the Preznit. And don't be surprised at any bad news for the rest of us.
Later....
Update 11/01/04:
