Thanks Jeff. Here's another from CNN: http://www.cnn.com/2005/TECH/space/01/14/huygens.titan/index.html What's intereting to me about the surface image is the apparent roundness and smoothness of the rocks/ice blocks in the foreground. To this amateur, it looks like they may have been exposed to a liquid environment of some kind.
