The Time Travelers1964

Dr. Varno:
We have been constantly surveying every possible planetary body in our solar system. Every planet. Every one of their moons. Even some of the smaller asteroids, but... This is the last; Titan, one of Saturn's largest atmosphere-carrying moons.

Dr. Erik von Steiner:
Robot surveyors?

Dr. Varno:
Yes.

Dr. Erik von Steiner:
You don't seem encouraged.

Dr. Varno:
The analysis shows a complete negative response. I'd expected it.

Dr. Erik von Steiner:
But you still maintain surveillance. Why?

Dr. Varno:
Information, Dr. Von Steiner. Knowledge. We feel we can never have enough of that in the new world we are going to occupy. There it is - our entire solar system. And nowhere can Man exist. Nowhere! Including Earth.
