Summary

The White House released a policy on April 14, directing NASA, the Pentagon, and the Department of Energy to develop space nuclear power systems, with initial launches projected as soon as 2028. This policy, designated NSTM-3, aims to provide sustained electricity, heating, and propulsion essential for permanent robotic and human presence on the Moon, Mars, and beyond. NASA is tasked with developing a "mid-power" (20-kilowatt) space reactor for lunar surface operations by 2030, while the Defense Department will support these efforts and later conduct its own competitions, and the Department of Energy will assess the nuclear industrial base and conduct R&D. The initiative seeks to reverse a long-standing trend of unfunded nuclear projects, building on NASA's existing SR-1 Freedom mission, to establish U.S. superiority in space. The policy emphasizes parallel design competitions and collaboration across multiple government agencies to deploy flight-proven nuclear systems.

Key takeaway

The White House's NSTM-3 policy mandates NASA, DoD, and DoE to accelerate development of space nuclear power systems, targeting initial deployment by 2028. NASA is directed to develop a 20kW lunar-capable reactor, with DoD supporting and later conducting its own competitions, to enable sustained robotic and human presence on the Moon and Mars. This policy aims to establish flight heritage and activate the industrial base for fission power, reversing past failures and ensuring long-duration mission capabilities.
