THE VOYAGER GOLDEN RECORD

The Voyager Golden Records are two phonograph records that were included aboard both Voyager spacecraft launched in 1977. The records contain sounds and images selected to portray the diversity of life and culture on Earth, and are intended for any intelligent extraterrestrial life form who may find them. The records are a sort of time capsule. Although neither Voyager spacecraft is heading toward any particular star, Voyager 1 will pass within 1.6 light-years' distance of the star Gliese 445, currently in the constellation Camelopardalis, in about 40,000 years. Carl Sagan noted that "The spacecraft will be encountered and the record played only if there are advanced space-faring civilizations in interstellar space, but the launching of this 'bottle' into the cosmic 'ocean' says something very hopeful about life on this planet.

The contents of the record were selected for NASA by a committee chaired by Carl Sagan of Cornell University. The selection of content for the record took almost a year. Sagan and his associates assembled 115 images and a variety of natural sounds, such as those made by surf, wind, thunder and animals (including the songs of birds and whales). To this they added musical selections from different cultures and eras, spoken greetings in 55 ancient and modern languages including a spoken greeting in English by U.N. Secretary-General Kurt Waldheim, other human sounds, like footsteps and laughter (Sagan's), and a printed message from U.S. president Jimmy Carter. The record also includes the inspirational message Per aspera ad astra in Morse code.

The collection of images includes many photographs and diagrams both in black and white, and color. The first images are of scientific interest, showing mathematical and physical quantities, the Solar System and its planets, DNA, and human anatomy and reproduction. Care was taken to include not only pictures of humanity, but also some of animals, insects, plants and landscapes. Images of humanity depict a broad range of cultures. These images show food, architecture, and humans in portraits as well as going about their day-to-day lives. Many pictures are annotated with one or more indications of scales of time, size, or mass. Some images contain indications of chemical composition. All measures used on the pictures are defined in the first few images using physical references that are likely to be consistent anywhere in the universe.

The musical selection is also varied, featuring works by composers such as J.S. Bach (interpreted by Glenn Gould), Mozart, Beethoven (played by the Budapest String Quartet), and Stravinsky. The disc also includes music by Guan Pinghu, Blind Willie Johnson, Chuck Berry, Kesarbai Kerkar, Valya Balkanska, and electronic composer Laurie Spiegel, as well as Azerbaijani folk music (Mugham) by oboe player Kamil Jalilov. The inclusion of Berry's "Johnny B. Goode" was controversial, with some claiming that rock music was "adolescent", to which Sagan replied, "There are a lot of adolescents on the planet." The selection of music for the record was completed by a team composed of Carl Sagan as project director, Linda Salzman Sagan, Frank Drake, Alan Lomax, Ann Druyan as creative director, artist Jon Lomberg, ethnomusicologist Robert E. Brown, Timothy Ferris as producer, and Jimmy Iovine as sound engineer. It also included the sounds of humpbacked whales from the 1970 album by Roger Payne, Songs of the Humpback Whale.

The Golden Record also carries an hour-long recording of the brainwaves of Ann Druyan. During the recording of the brainwaves, Druyan thought of many topics, including Earth's history, civilizations and the problems they face, and what it was like to fall in love.

After NASA had received criticism over the nudity on the Pioneer plaque (line drawings of a naked man and woman), the agency chose not to allow Sagan and his colleagues to include a photograph of a nude man and woman on the record. Instead, only a silhouette of the couple was included. However, the record does contain "Diagram of vertebrate evolution", by Jon Lomberg, with drawings of an anatomically correct naked male and naked female, showing external organs. The pulsar map and hydrogen molecule diagram are shared in common with the Pioneer plaque. The 115 images are encoded in analogue form and composed of 512 vertical lines. The remainder of the record is audio, designed to be played at ​16 2⁄3 revolutions per minute. Jimmy Iovine, who was still early in his career as a music producer, served as sound engineer for the project at the recommendation of John Lennon, who was contacted to contribute but was unable to take part.

Sagan's team wanted to include the Beatles song "Here Comes the Sun" on the record, but the record company EMI, which held the copyrights, declined. In the 1978 book Murmurs of Earth, the failure to secure permission for the song is cited as one of the legal challenges faced by the team compiling the Voyager Golden Record. In the book, Sagan said that the Beatles favoured the idea, but "[they] did not own the copyright, and the legal status of the piece seemed too murky to risk." When asked about the obstacle presented by EMI with regard to "Here Comes the Sun", despite the artists' wishes, Ann Druyan said in 2015: "Yeah, that was one of those cases of having to see the tragedy of our planet. Here's a chance to send a piece of music into the distant future and distant time, and to give it this kind of immortality, and they're worried about money ... we got this telegram [from EMI] saying that it will be $50,000 per record for two records, and the entire Voyager record cost $18,000 to produce. "However, this was denied in 2017 by Timothy Ferris; in his recollection, "Here Comes the Sun" was never considered for inclusion.
