With NASA determined to land humans upon the Moon by 2020, our civilization once again seems to be embracing the idea of people living among the heavens.
But at a cost of $100 billion, some skeptics are wondering whether or not our species can afford to establish cities upon other worlds, let alone lunar bases.
SpaceDev however thinks that the $100 billion price tag is too high, and seems to have a plan to pull off a lunar mission at under a tenth of the cost (with some estimates around $3 billion).
