Each of the Voyager spacecraft carried a greeting in the form of a 12-inch gold-plated copper phonograph record containing sounds and images portraying the diversity of life and culture on Earth. The contents of the record were selected for NASA by a committee chaired by Carl Sagan of Cornell University. Dr. Sagan and his associates assembled 115 images and a variety of natural sounds. To this they added musical selections from different cultures and eras, and spoken greetings from Earth-people in fifty-five languages.
