A committee chaired by astronomer Carl Sagan selected 116 images, natural sounds, music from diverse cultures, and spoken greetings in 55 languages to represent Earth on a gold-plated phonograph record. The record was manufactured in Boulder, Colorado, gold-plated in Gardena, California, and installed on both Voyager spacecraft at the Jet Propulsion Laboratory before their 1977 launches. Committee members included Frank Drake as technical director and Ann Druyan as creative director.
