Current Actions

The story of space exploration is being written every day…thank you for joining with us and becoming part of the story.

The Planetary Society's work to advance space science and exploration depends on people like you who believe in the value of discovery.

Let's get to work.

Tell Congress: We must say no to a "dark age" of space science at NASA

A leaked copy of the Trump Administration's 2026 budget request includes a staggering 47% cut to NASA's science programs. This is an extinction-level event for space science, upending decades of work and tens of billions in taxpayers' investment. Send a message to Congress to reject these cuts and restore proper funding to NASA science.

Ask your Representatives to join the Planetary Science Caucus

The Planetary Science Caucus is a bipartisan opportunity for members of Congress to show their support for science-driven exploration, the search for life, and planetary defense. Write and encourage your Representatives to join.

Become A Member

Joining The Planetary Society as a member helps prove that there is strong public support for space science and exploration.

"...we are told that, although the arguments for planetary exploration are widely understood in government, they are not supported by the people. We are told that spending money on planetary exploration—on the discovery of where we are, who we are, what our history and fate may be—is unpopular, that it is a political liability to support such ventures.

And yet there is evidence of enormous support and enthusiasm for the exploration of the planets... In puzzling over this apparent paradox, it became clear to me and a number of my colleagues that the solution would be a non-profit, tax-exempt, public membership organization devoted to the exploration of the planets and related themes... If such an organization had a substantial membership, its mere existence would counter the argument that planetary exploration is unpopular."
