Lost NASA telemetry data tapes
The Apollo 11 missing tapes were those that were recorded from Apollo 11's slow-scan television (SSTV) telecast in its raw format on telemetry data tape at the time of the first Moon landing in 1969 and subsequently lost. The data tapes were used to record all transmitted data, video as well as telemetry, for backup. Apollo 11 was also equipped with other imaging systems whose original high-resolution data survive, notably the 16mm Maurer Data Acquisition Camera, which recorded Armstrong's descent down the ladder and approximately 86 minutes of the lunar EVA, as well as Hasselblad 70mm still cameras. To broadcast the SSTV transmission on standard television, NASA ground receiving stations performed real-time scan conversion to the NTSC television format. The moonwalk's converted video signal was broadcast live around the world on July 21, 1969 (2:56 UTC). At the time, the NTSC broadcast was recorded on many videotapes and kinescope films. Many of these low-quality recordings remain intact...
