The Planetary Society exists to excite and empower space advocates by giving them a meaningful role in space science and exploration.

When you become a member, you join a mission to increase discoveries in our solar system and beyond, elevate the search for life outside our planet, and decrease the risk of Earth being hit by an asteroid.

We ask the big questions, take action, and seek answers through science and exploration. We believe that we know ourselves better when we know our place in space. We are a way for the universe to know itself.
