Pioneer 10 was a spacecraft launched by NASA in March 1972. Its aims were to study the planets Jupiter and Saturn as well as the edges of the Solar System. The spacecraft also carried one of two plaques, the Pioneer plaques. On the plaques were images that held some information about humans and earth. The other plaque was on Pioneer 11. The plaques were designed by a team lead by Carl Sagan to communicate with extraterrestrial life should the spacecraft come into contact with it.
