The two Voyager spacecraft each carried a phonograph record containing a variety of images and sounds from Earth, to be found and played by an extraterrestrial civilization. "...the launching of this bottle into the cosmic ocean says something very hopeful about life on this planet." (Carl Sagan, JPL Universe, 8/5/77)

In the image above, a technician works on one of the two Voyager golden records and its protective jacket.
