Your advocacy works! Congress just passed a bill that delays a rule that would've fundamentally changed how science is done in the United States, by handing power over research funding to political appointees instead of scientists. Learn more and get updates: www.planetary.org/save-nasa-sc...

IT WORKED! Thousands of you wrote your senators, and the Senate passed a funding bill pausing the OMB rule that would hand political appointees control over science grants. But it's not over: the House's bill doesn't include the pause. Tell your Rep to back the Senate's language: planet.ly/cPbNu

❗This rule would end peer review as we know it at NASA. For 80 years, experts decided which federal research gets funded based on merit. A new OMB rule would give politicians final say instead. But this isn’t over yet. Comment by July 13: www.planetary.org/ombgrantrules

OMB proposed new rules that would let political appointees, not scientists, decide which research gets funded in the U.S. But we can stop this if enough people share why peer-reviewed science is important to them. We made it easy for you to tell your story. The deadline to submit is July 13th.
