FILE – In this July 24, 1969 photo from the U.S. Navy, Lt. Clancy Hatleberg closes the Apollo 11 spacecraft hatch as astronauts Neil Armstrong, Michael Collins, and Buzz Aldrin, Jr., await helicopter pickup from their life raft after splashdown in the Pacific Ocean, 900 miles southwest of Hawaii, returning to Earth from a successful lunar landing mission. His mission was to decontaminate the astronauts and their command module, Columbia, immediately following splashdown. (Milt Putnam/U.S. Navy via AP)
