NASA is set to lose approximately 3,870 employees, representing about 20% of its workforce, through a voluntary resignation program initiated under President Donald Trump's administration. This reduction follows earlier reports that over 2,100 senior-ranking NASA staff, including 1,818 employees involved in mission-critical areas such as science and human spaceflight, were preparing to leave the agency amid efforts to shrink the federal workforce. The departures are driven by early retirement offers, buyouts, and deferred resignation options as part of a broader White House push to reduce federal staffing levels. The workforce decline will reduce NASA's civil servant employees from over 18,000 to roughly 14,000. This substantial reduction raises concerns about the agency's capacity to maintain key programs, including crewed missions to the Moon and Mars, especially amid leadership uncertainties and tensions with private sector partners like SpaceX.
