Space travel to Mars really interests me.  It has seasons very similar to Earth.  What is your favorite planet?
I guess I like Saturn, just because of the rings. I don't know about travelling to Mars though.
NASA has sent space exploration to Saturn, via the Cassini-Huygens mission.  The purpose was to study the planet, rings, and moons.
Yes, but I'm sure no one could live there. I would assume Mars might be more liveable.
No Saturn is composed of iron-nickel and rock and many gases, so definitely not livable.  I think we'd have to find an inhabitable planet outside of our solar system.
