NASA Targets 2028 for Lunar Nuclear Power
Table of Contents
The United States is poised to bring nuclear energy to the Moon. Earlier this month, Sean Duffy, the acting head of the National Aeronautics and Space Management (NASA), announced an accelerated timeline for the Fission Surface Power program. The agency now aims to land a small nuclear reactor on the lunar surface by 2028. This represents a notable step toward establishing a sustained presence on the Moon and enabling more ambitious future missions.
This initiative isn’t about powering a lunar base in the traditional sense. Instead, the focus is on providing a reliable, continuous power source for scientific instruments, robotic systems, and potential resource utilization efforts – especially the extraction of water ice. this is a critical step for long-term exploration of the Moon,
stated Duffy during the announcement.
Why Nuclear Power on the Moon?
Lunar nights last approximately fourteen Earth days, during which temperatures plummet and solar power becomes unavailable. Current lunar missions rely heavily on solar arrays and batteries, limiting operational capabilities during these extended periods of darkness. A nuclear fission reactor offers a consistent, independent power supply, regardless of sunlight. This is crucial for continuous scientific data collection and operating life support systems for potential future habitats.
Did You Know?…
The Kilopower Reactor Using Stirling Technology (KRUSTY) was a precursor to the Fission Surface Power program, demonstrating the feasibility of nuclear fission power in a space habitat. Testing occurred at the Nevada National Security Site.

Challenges and Considerations
Deploying a nuclear reactor on the Moon presents significant engineering and safety challenges. Transporting the reactor, ensuring its safe operation in the harsh lunar environment, and mitigating potential risks associated with nuclear materials are all critical considerations. NASA is working closely with the Department of Energy (DOE) and commercial partners to address these challenges. The reactor will be designed with multiple layers of safety features, including automated shutdown systems.
Pro Tip: Understanding the difference between nuclear *fission* and *fusion* is key.This program utilizes fission – splitting atoms – a well-established technology. Fusion – combining atoms – is still under development.
The Artemis Program & Long-Term Lunar Goals
This nuclear power initiative is directly linked to NASA’s Artemis program, which aims to return humans to the Moon and establish a sustainable lunar presence. The availability of reliable power will be essential for supporting Artemis missions, enabling in-situ resource utilization (ISRU), and paving the way for future exploration of Mars. Sustainable lunar power is not just about enabling science; it’s about building a foundation for a long-term, thriving presence on the Moon,
explains a NASA program overview.
NASA’s Fission Surface Power program is a game-changer for lunar exploration, offering a reliable and sustainable power source that will enable us to do more on the Moon than ever before.
The development of lunar nuclear power also has implications for deep space exploration.The technologies and expertise gained from this program could be applied to powering future missions to Mars and beyond.
What are your thoughts on the risks and rewards of deploying nuclear power on the Moon? Do you believe this is a necessary step for long-term space exploration, or are there choice solutions that should be prioritized?
lunar Power: A Past Context
The idea of using nuclear power in space dates back to the early days of the space race. The Soviet union experimented with nuclear reactors for powering satellites in the 198
