Last weekend, the Voyager spacecraft, launched from Earth in 1977, left the
solar system and headed into interstellar space. As it did, the ship carried an
unusual calling card, designed to introduce Earth to any alien being that the
Voyager might pass.
Traveling now billions of kilometers out in space are the voices and sounds of
humans and animals living on Earth in 1977. They are bolted to the side of
Voyager 1 in the form of a gold-plated phonograph record containing the sounds
of our planet.
Tim Ferris mixed the audio that went on the record.
"The record is a conventional long-playing phonograph record except that it is
made of copper and it is covered in gold and then it is put inside a titanium
case to protect it," he said.
Ferris was one of a small group of people who worked to convince NASA to attach
the record to Voyager's side. The original idea, according to Annie Druyan,
another member of the group, came from astronomer Frank Drake, at the University
of California.
"We wanted to convey to the extraterrestrials that we imagined what it was like
to be alive in the beautiful Spring of 1977, and it seemed to Frank that at the
time that the best way to compress as much information as possible in a very
small space was to do it on a
phonograph record," she said.
And there's plenty of information there. The record contains greetings in 59
human languages. It has 118 pictures of life on earth, and 27 pieces of music
exemplifying the diversity of human creation. Ferris mixed the audio that went
on the record.
"There is music on the record from Europe and the United States," he said. "But
also from Africa, the South Pacific and South America... Georgia, Russia, all
these places - China, India."
The technology they used may seem archaic today. But actually, Margaret
Weitekamp, a curator at the Smithsonian National Air and Space Museum, says it
has advantages over some of today's gadgets.
"It's a really durable technology that has proven to be a great way to record
sound," she said. "If you have digital sound, you have to have the right
software in order to decode it or it doesn't work."
And she says, if a spacecraft were launched today with a message for aliens, it
might still be a wise technology to use. So that's the medium. As for the
message they chose, Ferris says you couldn't have picked anything better.
"You can't say that an Indian raga or a piece by Bach or a Japanese Shakuhachi
piece 'means' something that you can put into words. It is its own end product,"
he said. "It means really what it is. Similar to things in nature. A flower
isn't a way of expressing
something else. It is the end product. It is what it is."
