University of Hawaiʻi Students Develop Nuclear Power System for Lunar Missions
A team from the University of Hawaiʻi has designed Project PETAL, a nuclear-powered energy system for the Moon, as part of a national competition. This innovation addresses the challenge of sustaining astronauts during prolonged periods of darkness on the lunar surface.

Project PETAL, developed by students from the University of Hawaiʻi at Mānoa and Hilo, is a nuclear-powered energy system aimed at supporting future lunar missions. The project was a finalist in the Revolutionary Aerospace Systems Concepts-Academic Linkage competition, marking the first participation from Hawaiʻi in its 25-year history.
Project PETAL utilizes small nuclear reactors instead of traditional batteries, storing excess heat in lunar soil for energy distribution through buried power lines. The initiative involved collaboration among students from different islands, focusing on power systems and sustainability.
The technologies developed could also be applicable for Mars missions. Competition results may influence funding and research directions for future lunar projects.
