We have at last glimpsed the surface of the fabled world, Titan, Saturn's largest moon and the greatest single expanse of unexplored territory remaining in the Solar System today.

Remember, Voyager was just a flyby, Cassini is in orbit. We have the opportunity for monitoring them and their behavior, their comings and goings, how they evolve, when they appear and disappear.

All the atoms of our bodies will be blown into space in the disintegration of the solar system, to live on forever as mass or energy. That's what we should be teaching our children, not fairy tales about angels and seeing grandma in Heaven.

We humans, though troubled and warlike, are also the dreams, thinkers, and explorers inhabiting one achingly beautiful planet, yearning for the sublime, and capable of the magnificent.

Saturn is the most photogenic planet in the solar system.

Being a scientist and staring immensity and eternity in the face every day is as grand and inspiring as it gets.

For planetary explorers like us, there is little that can compare to the sighting of activity on another solar system body. This has been a heart-stopper, and surely one of our most thrilling results.
