Pioneer Plaque

Pioneer Plaque

The Pioneer plaques are a pair of gold-anodized aluminium plaques which were placed on board the 1972 Pioneer 10 and 1973 Pioneer 11 spacecraft, featuring a pictorial message, in case either Pioneer 10 or 11 is intercepted by extraterrestrial life. The plaques show the nude figures of a human male and female along with several symbols that are designed to provide information about the origin of the spacecraft.

The Pioneer spacecraft were the first human-built objects to leave the Solar System. The plaques were attached to the spacecraft's antenna support struts in a position that would shield them from erosion by stellar dust.

The Voyager Golden Record, a much more complex and detailed message using (then) state-of-the-art media, was attached to the Voyager spacecraft launched in 1977.

Famous quotes containing the word pioneer:

    The poet is no tender slip of fairy stock, who requires peculiar institutions and edicts for his defense, but the toughest son of earth and of Heaven, and by his greater strength and endurance his fainting companions will recognize the God in him. It is the worshipers of beauty, after all, who have done the real pioneer work of the world.
    Henry David Thoreau (1817–1862)
