NASA digitized, decrypted and published 19,000 hours of audio recordings of all staff involved in ensuring the landing and return of the Apollo 11 mission to the Moon. July 20, 1969, the astronauts landed on the Earth’s satellite. And many of their negotiations have become public. However, the current archive covers for the first time all the negotiations of the NASA team.

Using the software for speech processing, researchers and volunteers spent five years digitizing and decoding the records: who, with whom and what they are talking about. As a result, there were 19,000 hours of audio recordings – about 2.16 years of continuous listening to the talks.

You can familiarize with them on the site Archive.org  or on the specialized site of NASA .
