I was about to say, Ray Bradbury's Martian Chronicles is about us going to Mars, followed by nuclear war.

...I actually was talking about this stuff to an aerospace engineer a few years back, and discussed problems with making planets (not Earth-sized and not in the "goldilocks" zone) habitable. Things like weaker gravitational and magnetic forces resulting in a much weaker atmosphere, and all. If I remember, it was thought to build under the planet's surface. With the plans for 3D printed structures in space, it could work. Would need to make it compartmentalized and create a sustainable environment inside the building (plants and all?)
