NASA and Energy Department expand partnership on space nuclear reactors
NASA and the Department of Energy signed a memorandum to collaborate on space nuclear technology, including research, fuel production, testing, and launch integration. NASA Administrator Jared Isaacman said the agency aims to launch a fission-powered spacecraft to Mars and has plans for a lunar reactor by 2030. The agency offered few details on progress beyond saying Lunar Reactor-1 is moving forward.
NASA and the Energy Department signed an unpublished memorandum to coordinate work on nuclear systems for space, covering research, fuel, testing, launch integration, and operations. Administrator Jared Isaacman described a new nuclear-focused era and said the goal includes a fission-powered Mars craft. Energy Secretary Chris Wright also signed.
The agency says Lunar Reactor-1 is advancing and should launch by 2030. A separate Space Reactor-1 would power Freedom, a Mars-bound vessel planned for December 2028, using a reused bus and more than 20 kilowatts for electric thrusters. It would carry three Ingenuity-type helicopters. GAO has long questioned NASA timelines, and Artemis has faced delays.
If these reactors advance, they could shape how governments and private firms plan deep-space missions, lunar bases, and power systems. Scientists and engineers may gain new capabilities for long-duration work, while taxpayers and policymakers could face cost and schedule risks. Launch safety and nuclear fuel handling may draw public scrutiny. Success could accelerate exploration; delays could reinforce doubts about ambitious timelines.
