In May 2017, a limited edition of 200 replicas engraved from the original master design at Precision Engravers was made available in a Kickstarter Campaign, which also offered laser-engraved replicas. The first plaque was launched with Pioneer 10 on March 2, 1972, and the second followed with Pioneer 11 on April 5, 1973. īoth plaques were manufactured at Precision Engravers, San Carlos, California. Additional artistic contributions were made by Jon Lomberg. Together with Frank Drake he designed the plaque, and the artwork was prepared by Linda Salzman Sagan, who was Sagan's wife at the time. NASA agreed to the plan and gave him three weeks to prepare a message. Sagan was enthusiastic about the idea of sending a message with the Pioneer spacecraft. He approached Carl Sagan, who had lectured about communication with intelligent extraterrestrials at a conference in Crimea. The original idea, that the Pioneer spacecraft should carry a message from mankind, was first mentioned by Eric Burgess when he visited the Jet Propulsion Laboratory in Pasadena, California, during the Mariner 9 mission. The plaques were attached to the spacecraft's antenna support struts in a position that would shield them from erosion by interstellar dust. The Pioneer 10 and 11 spacecraft were the first human-built objects to achieve escape velocity from the Solar System. 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 plaques are a pair of gold- anodized aluminum plaques that were placed on board the 1972 Pioneer Pioneer 11 spacecraft, featuring a pictorial message, in case either Pioneer 10 or 11 is intercepted by intelligent extraterrestrial life.
