White House announces plan for nuclear reactors on the moon
The White House is moving to fast-track nuclear power development in space, laying out a detailed road map with firm agency roles and time frames to put reactors on the moon and in orbit within the next decade.The new guidelines build on President Donald Trump’s executive order to ensure space superiority, which set a goal of deploying space-based nuclear reactors by 2030.The push builds on an announcement in August 2025 that NASA would develop a lunar reactor as part of an effort to compete with China and Russia in an intensifying space race, with the new guidelines bringing this goal closer to reality. The directive establishes the National Initiative for American Space Nuclear Power, a coordinated effort led by the White House Office of Science and Technology Policy. “Nuclear power will make sustained human presence in space possible,” OSTP Director Michael Kratsios said on social media. “We will survive the lunar might, endure Martian sandstorms, and venture into the stars.” Unlike earlier high-level proposals, the new memorandum assigns concrete responsibilities and deadlines to federal agencies, signaling a shift from concept to execution. The center of the plan is a dual-track development strategy. The Trump administration is directing both NASA and the War Department to run parallel design competitions for low- to mid-level power reactors so the high-powered reactors will be prepared to deploy by 2030. “The United States will lead the world in developing and deploying space nuclear power for exploration, commerce, and defense,” the memorandum reads, adding that agencies will partner with private-sector innovators to help meet the objectives. “We want launching from the United States on U.S. rockets, buying U.S. in-space logistics, and landing on U.S. re-entry ranges, to be easy and routine,” Kratsios said Tuesday. Near-term objectives include safely deploying nuclear reactors in orbit as early as 2028 and on the moon as early as 2030. Officials cast the plan as both urgent and intentional. “Americans are both dreamers and a people of action,” Kratsios said, tying the initiative to earlier space milestones. “There is nothing natural or inevitable about the quest for space. … America chose to be a space superpower.” JOHNSON BACKS EXPELLING SHELIA CHERFILUS-MCCORMICK FROM HOUSE The guidance underscores that nuclear power is key to sustaining long-term missions, providing the sustained electricity, heating, and propulsion needed for a perman...
US could put nuclear reactors in space, moon in next few years
The United States is planning to put nuclear reactors in space within the next 3-4 years, according to a report. The White House recently released a policy memo stating that NASA will soon initiate a program to develop a mid-power space reactor with a lunar fission surface power (FSP) variant, ready for launch by 2030. The agency can plan to develop a space variant for a nuclear electric propulsion (NEP) demonstration. Fission power systems NASA will partner with multiple vendors to develop fission power systems (including the reactor and power conversion) through at least a preliminary design review and ground tests that demonstrate hardware performance (potentially, but not necessarily, including a full-system ground test), pending successful achievement of all milestones, according to the memo.The White House’s overall strategy is to conduct parallel and mutually-reinforcing NASA and Department of War (DOW) design competitions to enable near-term demonstration and use of low- to mid-power space reactors in orbit and on the lunar surface, and prepare to deploy high-power reactors in the 2030s.The memo also mentioned that NASA should prioritize integrated designs for mid-power FSP and NEP, using common elements (including reactor hardware and nuclear fuel) and mature, demonstrated technologies to the extent reasonable for both applications. Set to be designed for compatibility with launch vehicles NEP variants will be designed for compatibility with launch vehicles that will be readily available by 2029, and should ensure that planning for power usage does not drive the overall technical, cost, or schedule risk of the project. iv. The mid-power reactors will be designed to provide at least 20 kilowatt electric (kWe) during at least 3 years in orbit and at least 5 years on the lunar surface, as per the memo.The report also highlighted that NASA should consider including one low-power reactor among its selections, designed to provide at least 1 kWe, if doing so offers lower cost and schedule risk. For any development of a low-power option, NASA should consider opportunities to leverage common technologies for mid-power FSP and NEP. Reactor design proposals should consider extensibility to higher power levels, and at least one selected design should be for a reactor that is extensible to at least 100 kWe, according to the memo. Michael Kratsios, the director of the White House’s science and technology policy office, unveiled the policy at the Space Sy...
