One giant blunder for mankind: how NASA lost moon pictures

The heart-stopping moments when Neil Armstrong took his first tentative steps onto another world are defining images of the 20th century: grainy, fuzzy, unforgettable.

But just 37 years after Apollo 11, it is feared the magnetic tapes that recorded the first moon walk - beamed to the world via three tracking stations, including Parkes's famous "Dish" - have gone missing at NASA's Goddard Space Centre in Maryland.

A desperate search has begun amid concerns the tapes will disintegrate to dust before they can be found.
