The public should have a say in space exploration.
We make that possible.
Our Approach
Space missions don't just happen.
The robotic craft that voyage beyond our solar system; the rovers that scour the sands of Mars, the spacecraft seeking signs of life beyond Earth—every mission is a choice made and remade over years, even decades, by elected officials who control funding and policies of national space programs.
The Planetary Society's Space Policy & Advocacy program works to ensure our societies keep making these choices.
To achieve this, we rely on our biggest strength: our global membership of space fans and advocates. We provide the training, tools, and opportunities to engage in the civic process.
But we don't stop there. We pair this with original policy research and a dedicated D.C.-based staff that works year-round to educate, advise, and elevate space policy issues.
“Meeting so many of our Representatives and Senators and all their staff members gave me an incredibly powerful vision of how The Planetary Society works with Congress to support NASA. I got to understand the role that we passionate, enthusiastic citizens play in ensuring the continuation and growth of NASA's amazing endeavors.”
–Philip K., Planetary Society member and Day of Action participant
