The Day of Action

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.

The next Day of Action will occur in the Spring of 2026

Research has shown that in-person constituent meetings are 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.

Registration includes:

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 with opportunities for more
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.

Experience Level:

Anyone is welcome to participate, whether you're an experienced space advocate or a new space fan. Minors must be accompanied by a parent or guardian.

Citizenship Requirements:

Anyone with a U.S. address is welcome to attend.
