From space.com:A newly released study has focused on how best to return people to the Moon, reporting that future lunar missions can be done for under $10 billion - far less than a NASA price tag.
The multi-phased three-year study was done by a private space firm, SpaceDev of Poway, California, and concluded that safe, lower cost missions can be completed by the private sector using existing technology or innovative new technology expected to be available in time to support human exploration of the Moon in the near-future.
