NASA plans lunar nuclear reactor by 2030

NASA is pushing to place a small nuclear reactor on the Moon by 2030 to power a future base, a plan that attracts questions about cost and safety.

NASA targets lunar nuclear reactor by 2030

NASA has directed planners to develop a nuclear reactor of at least 100 kilowatts electric for a Moon base, with a target launch by 2030. The reactor would be modest in size, generating power for a fraction of a Moon settlement and still far below Earth-based reactors. The move comes as the United States seeks lunar leadership amid rival ambitions from China and Russia.

On the technical side, the reactor would work much like Earth reactors but must shed heat into space through large radiators, since the Moon lacks air or water to carry away heat. Activation would occur only after the craft reaches a safe orbit away from Earth. Officials describe safeguards and a multiagency process, given the stakes for safety and long-term stewardship.

The plan blends urgent political signaling with real engineering risk. Accelerating a complex nuclear system to a 2030 target may strain NASA budgets and staff, especially as the agency contends with broader budget pressures. The move could shift attention from science and discovery to power logistics and risk management, potentially dampening broader scientific gains.

At the same time, the clock is ticking. International competitors could claim lunar presence first, a reality that pressures rapid decisions but also argues for careful governance and international collaboration. A multiyear authorization process that includes NASA, the Energy Department and safety regulators is essential to balance ambition with safety.

Highlights

The coming years will test whether ambition stays grounded in safety and budget realism.
