We're going to learn some tough stuff today about the White House's proposed budget for fiscal year 2026—including what they have in mind for NASA. I'll share what I hear, but remember: CONGRESS decides how much money NASA gets, not the White House. So whatever happens today, the fight continues.

How bad will it be? Catastrophic. Proposed cuts to #NSF, #NIH, and #NASA will set the US R&D landscape back 25 yrs+, cause economic and job loss now, and undermine innovations to come. But, this is the WH's *proposed* budget. Speak up now before it is too late. (inflation adjusted $-s below)
NSF, NASA and NIH budgets per year, inflation adjusted from 2000-2025 along with the proposed cuts. NSF includes research component only. Massive cuts across all sectors, well below support spanning 25 years.
