This collection consists of material created by and related to The Planetary Society since its beginning in 1980 and up to 2016.

The Planetary Society was founded in 1980 by Carl Sagan, Bruce Murray, and Louis Friedman. Its initial purpose was to demonstrate that the public strongly supported planetary exploration and the search for extraterrestrial life. As the group expanded its membership, it began sponsoring research projects, publishing a magazine and a website, holding events to celebrate exploration, and educating young people. The Planetary Society is the largest and most influential public space organization group on Earth. It is based in Pasadena, California.
