NASA is set to lose approximately 3,870 employees, representing about 20% of its workforce, due to a voluntary resignation program initiated under the Trump administration's broader effort to reduce the federal workforce. Earlier reports indicated that over 2,100 senior-ranking NASA employees planned to leave the agency, including 1,818 staff involved in mission areas such as science and human space flight. The departures are driven by early retirement offers, buyouts, and deferred resignation options as part of the agency's push to shed staff in line with proposed White House budget cuts. This workforce reduction affects key NASA centers, including the Kennedy Space Center and the Marshall Space Flight Center. The reduction in staff raises concerns about the potential impact on NASA's critical programs, including plans for crewed missions to the Moon and Mars. NASA's civil servant workforce is expected to shrink from over 18,000 to about 14,000 employees following these departures.
