“In 1977, NASA followed this up with the famous Golden Record attached to the Voyager 1 spacecraft.
These spacecraft – as well as their twins, Pioneer 11 and Voyager 2 – have now all left the solar system”
That’s slightly misleading. Voyager 2 also has a copy of that record, and it was launched before Voyager 1 (16 days earlier). The numbers are reversed because Voyager 1 arrived at the outer planets before Voyager 2 did.
