Global Day of Action: 10 February 2020

The Planetary Society's Day of Action was on 10 February 2020. More than 100 Society members from 28 states around the U.S. came to Washington, D.C. to advocate for space science and exploration. Thousands more around the world participated online by contacting their representatives in government and sharing space with their friends.

The Day of Action is an annual event and occurs in the Feb - March timeframe. Registration begins on 1 September. If you would like to be the first to hear about next year's Day of Action, subscribe to our monthly Space Advocate Newsletter.
