Arkansas' lost moon rock found in Clinton's files

For years, Arkansas historians have searched for a valuable lunar rock from the Apollo 17 mission, one of the moon rocks NASA presented to each state in the 1970s.While other states also continue to dig for the rocks that came to be known as the Goodwill Moon Rocks, the mystery in Arkansas was solved -- sort of -- when an archivist discovered it in former President Bill Clintons gubernatorial papers.Bobby Roberts, director of the Central Arkansas Library System, told Reuters the archivist opened a box previously archived as Arkansas flag plaque. The tiny flag was also sent to space, Roberts said. The rock was inside.The moon rock, which is in a plastic container, had fallen off the plaque, Roberts said. The archivist immediately knew what he had discovered.Other states such as New Jersey and Alaska have also misplaced their Goodwill rocks, which some experts estimate could be worth millions of dollars.Some states have found theirs in recent years, including Colorado, where former Governor John Vanderhoof confessed in 2010 he had the rock in his personal collection and agreed to give it back to the state.Roberts, who worked for Clinton when he was governor, said the moon rock was presented to Governor David Pryor in 1976. He could only speculate about how Clinton ended up with it.
