The Voyager spacecraft were launched in 1977.
They were sent into space bearing golden
records.
Each record contained, on one
side, instructions for playing the record
and some information about the senders
(us)
(learn
about the symbols).
On the other side, a record entitled
"The sounds of Earth" had all kinds of good
stuff which you can listen to
here.
Highlights include "Greetings from Earth" in
55 different languages and "Sounds of Earth"
of all kinds.
Currently, Voyager 1 is more than 90 AU from the
Sun and Voyager 2 is just a little bit less
(though on a different trajectory).
There are also
600,000
signatures visiting Saturn onboard Cassini and
about
70,000 signatures onboard the Mars rovers.
