Whoever you are, you have the power to make space exploration happen. Join us!


In 1980, Carl Sagan, Louis Friedman, and Bruce Murray founded The Planetary Society. They saw that there was enormous public interest in space, but that this interest was not reflected by government investment, as NASA’s budget was cut again and again.

Today, The Planetary Society continues this work, under the leadership of CEO Bill Nye, as the world’s largest and most influential non-profit space organization. The organization is supported by over 50,000 members in over 100 countries.

We introduce people to the wonders of the cosmos, bridging the gap between the scientific community and the general public to inspire and educate people from all walks of life.

We give every citizen of the planet the opportunity to make their voices heard in government and effect real change in support of space exploration.

We bring ordinary people directly to the frontier of exploration as we crowdfund innovative and exciting space technologies.

And we facilitate global collaboration for the advancement of space exploration.
