In 1977, NASA entrusted a small team of six individuals with the unique and daunting task of representing all of humanity to potential extraterrestrial civilizations. This mission was part of the Voyager space probes, which were launched to explore the outer reaches of the solar system and beyond. The team was given just six weeks and a modest budget of around $18,000 to create a message that would endure for tens of thousands of years, possibly even millions. This message, known as the Golden Record, was meant to be a time capsule of human culture, science, and sound for any intelligent life that might one day find it drifting through space. The idea came from John R. Casani, a project manager for the Voyager probes, who wanted to include a physical representation of life on Earth. Instead of using magnetic tapes, which could degrade in space, the team chose a more durable medium: a copper disc coated with gold, which would resist the harsh conditions of space. Carl Sagan, an astrophysicist at Cornell University, was asked to lead the project. He worked alongside Frank Drake, Ann Druyan, Timothy Ferris, Jon Lomberg, and Linda Salzman Sagan. Some of these individuals had previously collaborated on the Pioneer plaque, an earlier attempt to send a message into space. Together, they became the unofficial voice of humanity, tasked with selecting what would represent human civilization in its entirety. The team had to make crucial decisions about what to include on the record, from the music and languages to the images and written messages. They chose 116 images depicting human life, a 90-minute selection of music from around the world, and greetings in 55 languages. The disc also contains messages signed by then-U.S. President Jimmy Carter and the United Nations Secretary-General at the time, Kurt Waldheim. To help future discoverers understand the content without prior knowledge of human languages, the disc includes a "cosmic user manual" based on universal principles of mathematics and physics. The cover of the disc features a sample of uranium-238, a radioactive element with a half-life of 4.5 billion years, which can be used to determine how long the record has been traveling through space. Once the Golden Record was completed, NASA did not require any official validation of its content before launching the Voyager probes. After the probes were sent into space in 1977, no further changes were possible. The message was sealed, the probes launched, and the record set on a journey through the cosmos, where it will remain for eternity. This irreversible decision gives the Golden Record a philosophical weight, prompting reflection on what such a message might look like today. Despite its modest technical specifications, the Golden Record stands as a profound and ambitious effort by six individuals to capture the essence of humanity in just six weeks.
