Apollo moon rocks help transform understanding of the universe

- Moon rocks look rather nondescript -- they are often gray in colour -- but for NASA planetary scientist Samuel Lawrence, they are the "most precious materials on Earth."
"Many of the discoveries that we've made in planetary science, not just on the Moon, but on Mercury, on Mars, on some of the asteroids, directly relate to some of the results that we obtained during the Apollo missions."

"The (Apollo) astronauts only directly explored an area that's roughly the size of a large suburban shopping mall," Lawrence said. "There's a lot of places on the Moon that we haven't yet explored."
