NASA announced Friday that nearly 4,000 people have taken buyouts since President Donald Trump began shrinking the federal workforce earlier this year.

Secretary Brooke Rollins last week announced a reorganization of the Dept of Agriculture to save money.

Current and former employees at NSF, NASA, NIH, and the EPA have signed onto letters enumerating their concerns.

About 3,870 employees have applied to depart NASA over two rounds through the Trump administration's deferred resignation program, the agency disclosed.

NASA is bracing for one of the largest staffing reductions in its history, with nearly 4,000 employees preparing to exit under a federal downsizing initiative led by the Trump administration .

NASA’s course reversal on firing about 1,000 probationary employees in February was hailed as a victory for those opposing cuts to the space agency’s civil workforce, which in January comprised more than 18,000 personnel. According to the latest update, however, NASA could be 20 percent smaller by January 2026.

A letter of dissent titled "The Voyager Declaration," with hundreds of signatures from current and former NASA employees, said: "Thousands of NASA civil servant employees have already been terminated, resigned, or retired early, taking with them highly specialized, irreplaceable knowledge crucial to carrying out NASA's mission."

NASA plans a 20% workforce reduction as nearly 4,000 employees opt for voluntary resignations under Trump-era efficiency measures.
