Ark. Archivist Finds Missing Moon Rock

Last week, an archivist in Arkansas was sifting though boxes of papers from President Bill Clinton's gubernatorial years when he came across a surprise — a piece of the moon. The moon rock had been missing for about 30 years, and it was just one of about 180 moon rocks that are currently at-large. Melissa Block talks with retired senior special agent for NASA Joseph Gutheinz about the other missing rocks.
