Reposted by Ryleigh DavisThe Planetary Society @planetarysociety.bsky.social · 10/08/2026IT 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 03913
