NASA is facing internal opposition as hundreds of current and former employees, including at least four astronauts, have signed an open letter protesting the Trump administration's proposed 2026 budget cuts. The White House budget plan would reduce NASA's science funding by 47% and lead to mass layoffs, prompting workers to criticize the agency leadership for what they describe as "preemptive over-compliance" with the budget cuts. Employees warn that these reductions endanger safety and threaten to erase future U.S. science and technology advancements. In response, NASA workers have organized protests, including a "Moon Day" event on July 20, to oppose the cuts and layoffs. The dissent highlights concerns about the rapid and wasteful changes imposed on the agency, with some signatories expressing fears that speaking out could jeopardize their jobs.
