About 3,000 NASA employees applied to leave as part of the deferred resignation program, which closed its second round on July 25.

NASA will lose roughly 3,870 employees through a voluntary resignation program, part of a broad push from President Donald Trump’s administration to reduce the federal workforce.

NASA’s workforce is undergoing one of its largest reductions in decades, with nearly 4,000 employees choosing to resign through a deferred departure program backed by the Trump administration.
