Policy is the prime mover of space exploration. It sets in motion government resources, defines regulatory requirements, and releases funds from national treasures. Good policy is, therefore, critical for success in space.
The Planetary Society participates in the process of developing space policy by providing original analysis, releasing policy recommendations, and generating useful data for public and academic use.

The Search for Life as a Guidepost to Scientific Revolution (PDF)
In this submission to the 2023 - 2032 planetary science decadal survey, The Planetary Society argued for the importance of the search for life, not just as an inspiring goal, but as a means to achieve a scientific revolution within biology and medicine. Unlike past revolutions, searching for life presents a clear pathway for success: we know how to do it, and we know where to look.
