Everyone recognizes “One small step for man,” Neil Armstrong’s quote from July 21, 1969, as he stepped off of the steps of the lunar lander for the first time and onto the dusty regolith of the Moon’s surface.

What’s been lost over the years, however, are the hours and hours of conversations, commands, and quips passed from the Apollo 11 astronauts and Houston. Now, the public can hear all of it: Researchers, along with NASA, just released over 19,000 hours (or more than two years) of audio from Apollo 11, including Armstrong, Michael Collins, and Buzz Aldrin.
