Cash for Moon Rocks: How NASA Is Spurring Private Lunar Exploration
From 1969 to 1972, the National Aeronautics and Space Administration conducted a series of manned landings on the moon. They "planted the flag," played a little golf, and took some cool home movies. They also collected and brought back with them 842 pounds of assorted moon rocks for examination.
That's a lot of rocks, but now NASA wants more.
