FILE - In this 1969 file photo, astronauts Edwin E. Aldrin and Neil Armstrong rehearse tasks they will perform on the moon after landing in July 1969 during the Apollo 11 mission. The detection of a fake moon rock in the Netherlands' national museum should serve as a wake-up call for more than 130 countries who received gifts of lunar rubble from both the Apollo 11 flight in 1969 and Apollo 17 three years later. Experts say the whereabouts are unknown of hundreds of tiny rocks scooped up by U.S. astronauts and given by the Nixon administration to friendly nations.
