Space Exploration Challenges
The challenges in this section are those that must be solved before humans can regularly explore the moon, Mars, and nearby asteroids. It starts with the present challenge of affordable launch, and ends with the basic technologies needed to start outposts for settlement, in the next section.

Space Settlement Challenges
When the problems above are solved, humanity has the technology and economic depth necessary to begin space settlement. This starts with basic outposts that make their own water and fuel, then expands to a basic industrial and economic base. The definition of settlement ends with full independence from Earth and the ability to launch locally-sourced expeditions to other locations, such as the asteroid belt or outer solar system.
