There is a powerful recognition that stirs within us when we see our little blue ocean planet in the skies of other worlds. In an instant we can see how small, fragile, and alone we all really are.

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.

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

While I was there, Voyager flew by Saturn. I got involved with a person who was a member of the imaging team and started working on data from Saturn. With all that data coming in, the imaging team didn't have enough hands or scientists to work on all of it.

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

Let’s teach our children from a very young age about the story of the universe and its incredible richness and beauty. It is already so much more glorious and awesome - and even comforting - than anything offered by any scripture or God concept I know.

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.

It's been an adventure just getting out to Saturn, .. Saturn is such an alluring photographic target. It's a joy, really, to be able to take our images and composite them in an artful way, which is one of my cardinal working goals. It's about poetry and beauty and science all mixed together.

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.

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.
