The Planetary Society mobilized over 130 space advocates from 34 states and Washington, D.C. for the 2026 Day of Action on Capitol Hill. The coalition pressed lawmakers to sustain funding for NASA science programs facing budget pressures.
The grassroots campaign targeted key congressional offices, delivering data on how space science drives economic growth and technological innovation across American communities. Advocates emphasized that NASA's Earth science missions provide critical climate data, while planetary exploration programs support workforce development in aerospace and engineering sectors.
The timing reflects growing concern within the space community about flat or declining budget allocations for NASA's science divisions. Unlike human spaceflight programs, which command sustained public attention, robotic missions and Earth observation initiatives receive less political visibility despite their broad scientific value.
Participants distributed materials highlighting specific missions at risk, including Earth observation satellites and Mars rover operations. The Planetary Society framed the advocacy push as essential to maintaining American leadership in space science during an era of increasing international competition from China and the European Space Agency.
The Day of Action represents a coordinated push to reframe space science as infrastructure spending rather than discretionary spending, positioning research missions as investments in national competitiveness.
