Pioneer 10 & Pioneer 11 were space probes launched in the early 1970s designed to study Jupiter, Saturn, and the heliosphere. These probes were the first to fly through the asteroid belt and they also provided some of the best images of the gas giants of the time. As they continue to drift away, no longer in contact with Earth, they are among only 5 artificial objects with the velocity to the solar system. They are now over 10 billion miles from Earth.
A plaque with this same design was affixed to both Pioneer probes expected to leave the solar system; a message in a bottle for any extraterrestrial life that might find them. By wearing this pin, you are a pioneer—spreading human curiosity across the universe.

The Pioneer programs were two series of United States lunar and planetary space probes exploration. The first program, which ran from 1958 to 1960, unsuccessfully attempted to send spacecraft to orbit the Moon, successfully sent one spacecraft to fly by the Moon, and successfully sent one spacecraft to investigate interplanetary space between the orbits of Earth and Venus.
The second program, which ran from 1965 to 1992, sent four spacecraft to measure interplanetary space weather, two to explore Jupiter and Saturn, and two to explore Venus. The two outer planet probes, Pioneer 10 and Pioneer 11, became the first of five artificial objects to achieve the escape velocity that will allow them to leave the Solar System, and carried a golden plaque depicting a man and a woman and information about the origin and the creators of the probes, in case any extraterrestrials find them someday.
The pin is perfect. Exactly as shown on the website. Stemcell Science Shop never disappoints me.
