Cool indeed.
Neat-o.
I had the privilege of working on a small piece of the Cassini spacecraft years ago, as well as the Galileo. Sadly, the group I used to work with just got put on notice due to Nasa budget constraints.
The value of such discovery may not be evident for years..and may never do anything else but help expand our collective knowledge of the universe we inhabit..but dang, isn't that what we in these fine United States are all about? (off soapbox)
