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.
