Man that is friggin' awesome.
Unfortunately I'm unaware of any missions at all specifically directed at Titan even in the scribbling-on-envelope stage.

More dunes.. On Mars and Space.com
Scientists don't fully understand how dunes like this arise on Mars, but they owe to a complex relationship between the sandy surface and high winds. Low gravity and the size of sand grains may play roles. These dunes are in the 106-mile-wide (170 kilometer-wide) Proctor Crater.

Scientists also thought that the dark regions on Titan's equator were in fact seas of liquid ethane that trap sand. But the images reveal something different. "If you look at the dunes, you see tidal winds might be blowing sand around the moon several times and working it into dunes at the equator," Lorenz said. "It's possible that tidal winds are carrying dark sediments from higher latitudes to the equator, forming Titan's dark belt."So does this mean there aren't seas of liquid ethane on Titan? I wonder how that affects the chances of finding any kind of life there (not that it was ever a really good bet to begin with, I'm sure).

On Earth, all wind is ultimately a result of heat differences produced by sunlight that warms the planet unevenly. Scientists have long assumed Titan is too far from the Sun to have solar-driven surface winds powerful enough to cause sand dunes. I understand that Saturn, being a gas planet, gives off a good bit of heat... could that have an effect similar to the tides?

Saharan Sand Dunes Found on Saturn's Moon Titan I've been off line, moving, for the past week, so this is the first I've heard of this caper.
Do we know who stole them, or why? Or HOW?!?
Isn't silica common as dirt, throughout the system?

I guess the Sahara desert is a hell of a lot bigger than we thought, huh?
