NASA Pioneer 10 Space Probe Gold Plaque Ceramic Tile

NASA's Pioneer 10 space probe, which has now left our solar system, features this attached design engraved into a 6 x 9 inch gold-anodised aluminium plate in the event the spacecraft is ever found by alien life. The plaques show the figures of a human male and female, with the male’s hand up in a gesture of friendship, along with symbols designed to provide information about the origin of the spacecraft. Symbols include: Hyperfine transition of neutral hydrogen, figures of a man and a woman, relative position of the Sun to the centre of the Galaxy and 14 pulsars, our Solar System, and a silhouette of the spacecraft.
