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.

The same spiritual fulfillment that people find in religion can be found in science by coming to know, if you will, the mind of God.

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.

Spokes are one of those Saturn-system phenomena that we are keenly interested in understanding.

Cassini is different -- it's a mission of enormous scope and is being conducted in grand style. It is much more sophisticated than Voyager, ... I can't say it's got that flavor of romance, though. Voyager was very romantic. Cassini is spectacular.

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.

Nothing will ever be what the Voyager mission was.
