Take Action

Don't be a bystander for Planetary exploration. Be an advocate.

Space exploration doesn't just happen. It requires consistent and vigilant support by the public. Be a space advocate and reach out to your representatives in the House and Senate, or contact the President of the United States.

First, ensure that you are registered to vote in your district.

Then, take a minute to write to your Congressional representatives. Use the link below to use our convenient letter-writing tool that will send it to the right people.

Tell Congress to choose the best of two Planetary Science budgets
There is a $500 million difference between the House and Senate budgets for Planetary Science in 2019. Tell Congress to use the best budget for planetary exploration as they work to find compromise.
Ask your legislators to join the Planetary Science Caucus
There's a congressional congress for planetary exploration—and any member of Congress can join. Use this form to write your representatives to encourage them to be part of it and help promote space science.

It doesn't stop at writing a letter! Make sure to take the crucial follow-up steps and call your representatives' offices, schedule visits, or write opinion pieces in your local paper. Change starts one person at a time.

Note: we can no longer provide advocacy petitions for individuals outside of the United States due to restrictions imposed by the European Union's General Data Protection Regulations (GDPR).
