"Discovery.com and Space.com report this all changed when actual measurements were taken using the Mini-SAR and Moon Mineralogy Mapper (M3 or "M-cubed") instruments on India's Chandrayaan-1 moon probe and NASA's recent LCROSS mission when the moon was "bombed.""
As far as I know, only China has plans for a manned lunar base.
Japan and India have expressed some interest, and have sent some nifty probes/cameras. But I don’t think they’ve officially declared lunar base programs.
I’m sure someone will correct me if I’m wrong, this being FR!
