The Voyager twins are, in many respects, relics of their period. They each contain an eight-track tape recorder for storing data, 3 million times less memory than contemporary cellphones, and a data transmission rate that is around 40,000 times slower than a 5G internet connection. The Golden Record, which has greetings in 55 different languages, images of people and locations on Earth, and music ranging from Beethoven to Chuck Berry’s « Johnny B. Goode, » belongs to them both.
