The Society was founded in 1933 and is the world's longest established organisation devoted solely to supporting and promoting the exploration of space and astronautics. This is where Spaceguard UK is trying to help. You can contact them at the link here. The Planetary Society was founded in 1980 by Carl Sagan, Bruce Murray, and Louis Friedman to encourage the exploration of our solar system and the search for extraterrestrial life. With more than 100,000 members from over 140 countries, we are the largest space interest group on Earth.
Membership is open to all people interested in our mission.
