The problem with space is the insane amount of time it takes to get anywhere. Unless there really is a way to go faster than the speed of light, or wormholes exist.
Reading a cool book, 2312, where earth is in trouble, but there are "spacers" that have colonized the planets and their moons in the solar system. Some really creative things, like they have space elevators that can are attached to earth and are in orbit which can take people up to space where they can travel to other places. Mars has been terraformed, but most others they live in protected areas so they can live there.
One really cool thing is to travel around the solar system, they take meteors that are very large, hollow them out, and build terrariums that spin to create a g with soil, plants, animals, and there are all kinds of different ones. . The odd thing is when you look up to the sky you see the ground on the other side.
