The Golden Record: A Time Capsule of Human Experience Sent into Space
TLDR NASA sent two Voyager probes into space with a 12-inch Golden Record containing music, greetings in different languages, sounds from Earth, and encoded images. The probes are still functioning but their power is decreasing, and they are estimated to have about 10 years left before becoming time capsules in space.
Timestamped Summary
00:00
NASA sent robotic probes on a flyby mission to Jupiter, Saturn, Uranus, and Neptune, and included a 12-inch disk called the Golden Record that encapsulated the entire human experience.
02:00
The Voyager program was created to send two probes to the outer planets, and they would be the first human objects to leave the solar system and head out into interstellar space.
03:40
Astrophysicist Carl Sagan and Frank Drake decided to attach a record containing a representative collection of music from Earth to the Voyager 1 and 2 probes, which would be the first human objects to leave the solar system.
05:04
The Golden Record included music, spoken greetings in 55 different languages, random sounds from Earth, and 115 encoded images.
06:28
The Golden Record is made of copper and plated in gold, with images of people, places, and animals from all over the planet, and includes a message etched by hand by Timothy Ferris.
07:56
The Golden Record was never officially released commercially, but a Kickstarter campaign in 2016 raised over a million dollars to recreate it, and it was nominated for a Grammy award in 2018; the probes themselves are still functioning, with Voyager 1 passing through the Heliopause in 2012 and Voyager 2 passing it in 2018, but their power sources are decreasing and most of their instruments have been turned off to conserve power.
09:24
The Voyager probe has a weak signal that can only transmit at 160 bits per second, and it is estimated to have about 10 years of power left before it becomes a time capsule sailing through space.
