The sand dunes of Titan

[ajtribick]

The equatorial regions of Titan have been revealed to contain large sand dunes, rather than ethane oceans.

Seems that the evidence points to a dry Titan with occasional flash floods that result in the channels and short, intensive periods of erosion. Alternatively the sand could come from photochemical reactions in the atmosphere.

I just read this. Did you catch the descent videos that they put together?

I do wonder, though, if these are dynamic dunes, or if they are static, like many on Mars seem to be?
