The Day of Action is The Planetary Society's premier global advocacy event. We provide opportunities for members to take direct action to support planetary exploration, planetary defense, and the search for life.

Register by April 15th, 2024 to reserve your spot!

Training location and meetings will be around Capitol Hill in Washington, D.C.

Research has shown in-person constituent meetings to be the most effective way to engage elected officials on topics like space exploration. If you believe in a future of space, this is the way to show it.

  • Online and in-person advocacy training from The Planetary Society's space policy team
  • A minimum of three meetings with congressional offices booked for you by The Planetary Society
  • Access to special events, social gatherings, and space-themed experiences for you and fellow members while you're in D.C.

Not included:

  • Travel to and lodging in Washington, D.C.


Anyone is welcome to participate, whether you're an experienced space advocate or a new space fan. We provide training and resources to help you be the best advocate you can be.
