Japan plans on sending a humanoid robot to the moon in 2015 and is planning on setting up a whole robotic moon base for 2020. It will be unmanned in the flesh-and-blood sense, but will be populated with a 660 pound rolling bot. The station will be self-powered, and will let its citizen roam over 60+ miles of terrain, gathering scientific samples that can be sent back to earth. An HDTV station will beam back high definition broadcasts. The whole project will run somewhere in the ballpark of $2.2 billion, and will be developed simultaneously with Japan's manned moon program.
