The original recordings of the first humans landing on the moon 40 years ago were erased ... NASA officials said. NASA released the first glimpses of a complete digital make-over of the original landing footage that clarifies the blurry and grainy images of Neil Armstrong and Buzz Aldrin walking on the surface of the moon. The full set of recordings [is] being cleaned up by Burbank, California-based Lowry Digital. NASA admitted in 2006 that no one could find the original video recordings of the July 20, 1969, landing. Since then, Richard Nafzger, an engineer at NASA's Goddard Space Flight Center in Maryland, who oversaw television processing at the ground-tracking sites during the Apollo 11 mission, has been looking for them. The good news is he found where they went. The bad news is they were part of a batch of 200,000 tapes that were degaussed - magnetically erased - and re-used to save money. We should have had a historian running around saying 'I don't care if you are ever going to use them - we are going to keep them'," he said. They found good copies in the archives of CBS news and some recordings ... in film vaults at Johnson Space Center. Lowry, best known for restoring old Hollywood films, has been digitizing these ... to make a new rendering of the original landing. And there may be some unofficial copies of the original broadcast out there somewhere that were taken from a NASA video switching center in Sydney, Australia.
