Pioneer 12 or Pioneer H was the last of the Pioneer Space-probes sent out into space. On board, they carry the famous plates which show a man, a woman, and the location of our planet, meant for extra terrestrials to find and contact us in the slim chance that any would find it.
Their main mission, however, was to research our solar system and its planets to discover wether we could further our society in space. What could our solar system give us? Cosmetics? Water? Life? Or the end of our tiny dot in the universe?
