In 1977, as NASA was preparing to launch two spacecraft as part of the the Voyager Interstellar Mission, they enlisted astronomer/astrophysicist Carl Sagan and Ann Druyan, the creative director of the project, to create a golden record that would be sent into space on the spacecraft. It was to be the ultimate mixtape of the human experience, an audio introduction to humanity to whatever unknown life form listened to it; it included a kiss, a mother’s first words to her unborn child, greetings in 59 different languages, music from all over the world.
In the course of working together to find just the right mix of sounds and music, Sagan and Druyan fell in love, in a stunning, immediate and completely unexpected way. And that inspired additional sounds they curated for the record: they measured the electrical impulses of a human brain and nervous system and turned it into sound for the record. And since Druyan was to be the one whose brain and body were recorded, the sounds include what she was meditating on at the time “the wonder of love, of being in love”.
