Droplets on Lens
The crater-like dots are droplets of some ?hydrocarbon? liquid that condensed on the lens as Huygens descended through the clouds.
I'm intrigued by the many crystalline-like aspects of surface features - e.g. repeating triangular patterns in the light vs dark "fan" and angular "fractures" morphing into dendritic "rivers".
There may be some fundamental misconceptions in our understanding of the surface of Titan.
Time to brush-off the dust from my Sci-Fi novel... :-)
