19,000 Hours of Apollo 11 Audio Recordings

From Space.com:

Over the eight-day, 3-hour Apollo 11 mission, astronauts Neil Armstrong, Buzz Aldrin and Michael Collins stayed in constant communication with mission control and supporting teams. The back-and-forth conversations, which took place over what are called communication “loops,” were released to the media, because NASA is required to make its work public. But these fragile physical recordings had to be stored in special, climate-controlled vaults.

Now, thanks to a dedicated collaborative effort between NASA and the University of Texas at Dallas (UT Dallas), all 19,000 hours of audio recordings from the Apollo 11 mission have been converted into a digital format and are available online.
