At tracking stations in Australia and the United States, engineers recorded data beamed to Earth from the lunar module onto one-inch telemetry tapes. The tapes were recorded as a backup if the live transmission failed or if the Apollo Project needed the data later. Each tape contained 14 tracks of data, including bio-medical, voice, and other information; one channel was reserved for video.
A three-year search for these original telemetry tapes was unsuccessful. A final report on the investigation is expected to be completed in the near future and will be publicly released at that time.
