Overview
- President Trump’s FY2026 proposal would cut NASA’s topline about 24% to $18.8 billion and reduce the Science Mission Directorate by roughly 47%, with more than 40 missions flagged for defunding including Mars Sample Return, MAVEN and Juno.
- Roughly 300 advocates from about 20 organizations joined The Planetary Society’s Day of Action led by Bill Nye, who called the science cuts an “extinction-level event” and urged Congress to maintain existing, already funded programs.
- House and Senate appropriators have rejected the administration’s steep science cuts, with the Senate keeping NASA science near $7.3 billion and the House marking $6 billion versus the White House’s ~$3 billion request.
- With the government closed, essential spacecraft and ISS operations continue without pay for employees, and the Senate plans another vote to advance a continuing resolution after repeated failures to reopen the government.
- During the shutdown NASA has been directed to align operations to the House appropriations version that funds science at $6 billion, while reports of early implementation moves by OMB have heightened concerns about changes before Congress finalizes spending.
