Saturn Return is just the return of your planets to their original position.
We can't start over and develop a Saturn 5-type vehicle from scratch.
For me, it was my first cosmic connection, on par with a first kiss. No other planet looks as unworldly or surreal as Saturn. When you see it floating in the eyepiece of your telescope, you feel as if you've uncovered mystery in the cosmos.
Titan is Saturn's largest moon, and, until Cassini had arrived, there was the largest single expanse of unexplored terrain that we had remaining in our solar system.
It would be impossible in a few words to describe all that we've found with Cassini. No mission has ever gone as deep for as long on a planetary system as rich as Saturn's.
The Saturn system is a rich planetary system. It offers mystery, scientific insight, and obviously splendour beyond compare, and the investigation of this system has enormous cosmic reach... just studying the rings alone, we stand to learn a lot about the discs of stars and gas that we call the spiral galaxies.
The Cassini mission was all about a comprehensive investigation of Saturn and everything in the Saturn system, and it's been a mission that's been done jointly with the Europeans.
We must believe then, that as from hence we see Saturn and Jupiter; if we were in either of the Two, we should discover a great many Worlds which we perceive not; and that the Universe extends so in infinitum.
As you go further from the sun, Jupiter, Saturn and Uranus are each colder in their upper atmosphere. But when you get to Neptune, it's just as warm as Uranus.
On the technical side, Apollo 8 was mainly a test flight for the Saturn V and the Apollo spacecraft. The main spacecraft system that needed testing on a real lunar flight was the onboard navigation system.
