Pioneer Plaque

Launched in 1972 and 1973, Pioneers 10 and 11 both carry aboard them the six-by-nine inch gold plaque shown above. Pioneer 11 is no longer transmitting, but Pioneer 10 -- our first spacecraft to leave the solar system, now 6.6 billion miles away -- performed a successful maneuver and transmission as recently as January.

If some day the derelict Pioneer 10, its transmitter long since drained of energy, is picked up by an alien civilization, the plaque on its side represents both who we are and where we are in the galaxy.
