Don't forget Titan.

What makes Titan so interesting is that it has an atmosphere and is covered in organic molecules. Despite the fact that it's so cold that methane runs like water and ice is as solid as rock up there, it's actually pretty Earthlike in it's compositions. The same can be said for Venus, but that planet just doesn't have the abundance of organic molecules that Titan has. |
Maybe we can talk Saturn into a swap. Their promising moon for our dead and airless one.  |
We could just steal it! Just get a few asteroids redirected to ever so gently tug with their gravaty Titan out of Saturn orbit and over here. Heck while we are at it why don't we swap the orbits of Venus and Mars and move Europa and make it the new moon of Mars it could be a touristy water park while stablizing Mars's rotation and getting the old planet core spinning again. Now what about a moon for Venus? Anyone got an idea?

Launches could be done cheaply if in place of a rocket a magnetic catapult was used. Think Railgun with human cargo. Fling it in to LEO and have a trans-lunar shuttle pick it up. Then use a cycler to send the people to Mars. BTW a cycler is basicly a space station in a perabolic orbit that goes between Earth and Mars orbit. If we ever get a space elevator working off loading people from Earth would be dirt cheap, they could even live on the elevator much like in Clarke's 3001 and The Fountians of Paradise.
