A Message from Earth

In 1972 and 1973, NASA launched two space probes called Pioneer 10 and 11. Headed for the vast universe, these probes were designed with an added feature for the possibility of contact with extraterrestrial life.
Each probe has a plaque with a message from Earth engraved on it. The plaques are actually infographics about the Earth and the human race. They are still traveling deeper into space and transmitting signals back to Earth.
