Establishing a Permanent Power Grid on the Lunar Surface

Lockheed Martin is spearheading the development of Fission Surface Power (FSP) as the foundational technology required to transition from temporary lunar campsites to a sustainable human presence. Unlike solar-dependent systems, which are rendered ineffective during the two-week-long lunar night or within permanently shadowed craters, nuclear fission offers a consistent and independent energy supply. This capability is essential for maintaining life support in habitats, recharging rovers, and powering the specialized machinery needed for in-situ resource extraction. According to the company, these reactors will provide the reliable baseline of energy necessary to support a burgeoning lunar economy and ensure American leadership in deep space exploration.

A Strategic Response to National Space Priorities

The push for space-rated nuclear power has shifted from a theoretical interest to a national priority following a recent White House Executive Order. Bill Pratt, director of in-space infrastructure at Lockheed Martin, noted that the order effectively resolved the strategic "chicken and egg" dilemma regarding whether to prioritize power infrastructure or user demand. By establishing a guaranteed power source through the lunar night, the government is creating an anchor for future commercialization, allowing private industry to build business models around a stable energy grid. Lockheed Martin is currently executing Phase 1 contracts to mature these nuclear technologies, aiming for a mission-ready deployment by 2030.

Scalable Architecture for Growing Industrial Loads

The engineering philosophy behind the FSP program centers on a flexible, modular architecture that can grow alongside lunar operations. Initial deployments will focus on compact 5–10 kW systems designed to keep habitats warm and critical electronics functional during extreme cold cycles. As lunar activity expands into large-scale regolith mining for oxygen or the manufacturing of rocket propellant, the grid is designed to scale upward to 25, 50, or even 100 kW. This step-by-step approach reduces initial mission risk while providing a clear path toward the heavy-duty energy requirements of future industrial hubs and eventual Mars missions.
