On 5 September 1977, NASA launched Voyager 1, the second of two spacecraft on a grand tour of the solar system and the mysteries of interstellar space. Each spacecraft is equipped with a golden disc containing the greatest music on Earth, vocal greetings - the “Sounds of Earth” - and more than 100 images encoded as audio signals, a technological feat at the time. The engineers at Colorado Video projected each Voyager slide onto the lens of a television camera, generating a signal that their machine converted into several seconds of sound per photo. A diagram on the aluminum cover of the golden disc explains how to read it and decode the images. Four decades later, Ron Barry followed the instructions and tried to reproduce the efforts that an extraterrestrial would make to recover these images. For the researchers of the "Vus à 130" line, they are, in a way, the brown panels of our planet.
