Join The Planetary Society

From the first flight of my boyhood rubber band-powered airplane, I began searching for My Place in Space. Sitting in professor Carl Sagan's class years later, my path began to crystallize. Today I'm ecstatic to carry on my mentor's legacy as CEO of The Planetary Society.

At The Planetary Society, passionate space fans like you join forces to create our own missions, nurture new science and technology, advocate for space, and educate the world—all to advance space exploration. We’re your place in space!

Let's change the world together.
