The U.S. government has misplaced the original recording of the first moon landing, including astronaut Neil Armstrong's famous "one small step for man, one giant leap for mankind," a NASA spokesman said on Monday.
Armstrong's famous space walk, seen by millions of viewers on July 20, 1969, is among transmissions that NASA has failed to turn up in a year of searching, spokesman Grey Hautaloma said.
"We haven't seen them for quite a while. We've been looking for over a year and they haven't turned up," Hautaloma said.
The tapes also contain data about the health of the astronauts and the condition of the spacecraft. In all, some 700 boxes of transmissions from the Apollo lunar missions are missing, he said.
