The National Space Society (NSS) is proud to announce its participation in the upcoming Day of Action to Save NASA Science, taking place October 5–6, 2025, in Washington, D.C.

Hosted by The Planetary Society and supported by a coalition of leading space advocacy organizations, this event comes in response to a proposed 47% cut to NASA’s Science Mission Directorate (SMD) in the Fiscal Year 2026 federal budget.

NSS joins nearly a dozen partner organizations, including the American Astronomical Society, American Geophysical Union, Explore Mars Inc., and The Mars Society, to rally citizens, scientists, and students for in-person advocacy with congressional leaders. Together, the day of action aims to defend the scientific integrity and global leadership of NASA’s space science programs.

“We cannot afford to let decades of investment and international collaboration in space science unravel,” said Grant Henriksen, chair of the NSS Policy Committee. “This Day of Action is a call to every space supporter who believes in discovery, innovation, and a thriving future for humanity in space.”

Participants will receive training from space policy experts and meet with congressional representatives to urge restoration of NASA science funding, protect active missions from premature termination, and advocate for sustained investment in space science.

NSS encourages its members and the public to register and join this vital advocacy effort. Together, we can ensure that NASA continues to pursue its mandate: the expansion of human knowledge through exploration of Earth, the solar system, and beyond.
