Transcript: The first message to leave the solar system from humans towards aliens was attached to the leg of the Pioneer 10 spacecraft. It was a plaque designed, amongst others, by Carl Sagan and Frank Drake. This gold plaque contained graphics indicating aspects of human culture and indicating their intelligence. There were two naked human silhouettes, a map of the solar system showing the path of the Pioneer spacecraft, a schematic of the hydrogen molecule, a silhouette of the spacecraft itself, and most importantly a pulsar map showing aliens how to triangulate the distance of the Earth in terms of eighteen different pulsars whose frequencies were marked out in binary tick marks along the line of each pulsar. It’s again highly debatable whether anyone could understand or make sense of such a map. We would have to assume the visual sense and that they could understand or interpret the graphics that were represented on the plaque. Realistically, the Pioneer plaque should not be seen as an attempt to communicate but more as a message in a bottle thrown out into the depths of interstellar space to tell someone potentially far in the future that we exist, that we had a technology, and we were intelligent.
