We believe the public should inform space policy
through civic engagement
Our Approach
Space missions don't just happen. Smart policy and stable funding are critical for success in both private and public space exploration. To this end, The Planetary Society pursues political advocacy to guide legislation and to educate, train, and mobilize our members to be effective space advocates. We also generate space policy to help build consensus about where to explore and how best to get there.
The Planetary Society's Space Policy and Advocacy program
- Is independent—it accepts no corporate or government funding.
- Empowers individuals to be effective advocates for space exploration.
- Educates the U.S. Congress to support our core enterprises of planetary exploration, planetary defense, and the search for life.
- Develops original research and policy solutions to support the work of policymakers around the world.
"We need to make sure that we have groups like The Planetary Society always engaged, always interested. Get your friends involved, grow the base of the community that is necessary to support space exploration and the science and the discovery that goes along with it. I cannot tell you how important it is."
—NASA Administrator Jim Bridenstine on Planetary Radio, April 2020
