Can Earthlings Crowdfund a Moon Colony?

The idea of moon colony isn't quite so alien anymore.

Bigelow Aerospace LLC, a Las Vegas-based company that makes inflatable space habitats, has reached an agreement with NASA to study the possibility of returning men to the moon. It's part of a larger effort to identify government and private investments to advance human space exploration. Bigelow won't be paid for its work, which is scheduled to be completed this year.
