Makenzie Lystrup, director of NASA's Goddard Space Flight Center, announced her resignation effective August 1, with deputy director Cynthia Simmons set to serve as acting director. This departure comes amid growing unrest within NASA, where more than 280 current and former employees, including at least four astronauts, have signed a declaration opposing drastic changes proposed by the U.S. administration. These changes include budget cuts that many NASA workers warn could endanger safety and jeopardize the agency's future scientific and technological progress. The proposed funding reductions have sparked significant concern and criticism, with some officials and Democrats arguing that implementing these cuts before Congress passes a budget would be irresponsible and potentially illegal. The agency is reportedly experiencing a crisis characterized by political pressure, budgetary constraints, and a wave of resignations, raising questions about the future of U.S. space exploration efforts.
