Space Nuclear Power Corporation

Space Nuclear Power Corporation (SpaceNukes) is a US-based company specializing in the design and fabrication of fission reactor power systems for space applications, with a focus on enabling sustained operations on the Moon, Mars, and beyond. Founded in 2001, the company distinguishes itself by concentrating on practical, flight-ready reactor technology, contrasting with purely theoretical designs. SpaceNukes is currently focused on delivering high-confidence, reliable power solutions for near-term lunar and Martian surface missions.

A key technological achievement is the Kilopower Reactor Using Stirling Technology (KRUSTY), the only new reactor concept designed, developed, and tested in the United States in the last 50 years. This testing, conducted in 2018, demonstrates the company’s capabilities in reactor development and validation. SpaceNukes emphasizes its ability to deliver reactors capable of flight within a three-year timeframe, positioning it as a leader in rapidly deployable space nuclear power.

While specific customers are not publicly detailed, the company’s technology is clearly geared towards supporting NASA’s ambitions for long-duration lunar and Martian exploration and potential commercial ventures requiring substantial and reliable power sources in space. SpaceNukes’ unique value proposition lies in its commitment to “real” reactor development – moving beyond conceptual designs to deliver tested, flight-ready systems, addressing a critical need for sustained power in deep space environments.
