We’re fighting for science, engineering, and exploration.
Tell Congress to push back on the 2025 Presidential Budget Request that
cuts NASA Science by 47%, STEM education by 100%, and
NASA’s full budget by 25%!

This event is being organized as a one-off by a collection of people who love NASA and are watching it be cut to pieces. Because the harm is happening now, with more coming almost every day, we didn’t really have time to do everything the “right” way, such as by forming a named group with a proper website, or partnering with well-known organizations. The people organizing this protest are just folks who jumped in to hold a protest, because we think that NASA won’t be the same if we don’t act now.
We are a peaceful protest group, and we stand in solidarity with other scientific advocacy groups.
Current NASA leadership is already acting on the President’s and OMB’s proposed budget by beginning to greatly reduce the number of civil servants and contractors, which will be detrimental to the mission of this Agency. Cuts to NASA’s science budget will drastically hinder NASA’s ability to produce science from current and future missions. To win the Space Race to the Moon, NASA was prioritized and appropriated $68 billion in 1965 alone (adjusted for inflation). In 2026, with goals to reach Mars, NASA’s proposed budget is only $18.8 billion. Some of the cuts to NASA science involve turning off spacecraft that are already in space and actively sending back data. NASA contributes to agriculture, weather predictions, and safety. Without NASA Earth science, early detection for natural disasters and forecasting would be imprecise and difficult.
We understand that the lack of a well-established, persistent group is off-putting. If you would rather not join this protest then there are still ways you can help. Please absolutely flood your representatives in Congress with pleas to save NASA. When you do, drive home the point that the cuts are happening now! Most of Congress seems to think that they will save NASA if they work out a budget for the coming fiscal year that funds NASA at previous levels. They don’t realize that NASA’s acting administrator, under pressure from the White House, OMB, and DOGE, are enacting “realignments” and cuts now. So please please please tell Congress that every day our nation is losing dedicated and brilliant career civil servants, contractors, and programs, that NASA is being fed into the woodchipper now. Congress must act immediately to save NASA, not wait for October 1!
And thank you.
