Italy has embarked on an ambitious venture to develop small nuclear fission reactors aimed at powering future lunar settlements. This initiative, known as the SELENE project (Sistema Energetico Lunare con l’Energia Nucleare), is spearheaded by the Italian Space Agency (ASI) in collaboration with the National Agency for New Technologies, Energy, and Sustainable Economic Development (ENEA).

The project also involves the Department of Energy at the Politecnico di Milano and Thales Alenia Space Italia. The primary objective of SELENE is to establish a stable and continuous energy supply on the Moon, essential for sustaining human presence and activities.

Traditional solar energy solutions face significant challenges due to the Moon's 14-day cycles of light and darkness, making them unreliable for consistent power generation. To address this, the SELENE project proposes the development of the Moon Energy Hub (MEnH), which will utilize Surface Nuclear Reactors (SNRs) to provide a dependable energy source for lunar outposts.

The project, selected in 2023 as one of the winners of an ASI funding call for scientific experiments on the Moon, is set to span three years. It will involve multiple ENEA research centers, including those in Frascati, Casaccia, Bologna, and Brasimone. The research will focus on designing energy conversion and distribution systems, analyzing decommissioning processes, evaluating supply chain aspects, and creating a roadmap for the industrialization of the infrastructure.

A key component of the project is the development of advanced technologies in sensor systems, high automation, and wireless power transmission. One of the most challenging aspects under investigation is the heat dissipation system for the SNRs, which is crucial for validating the performance and enhancing the technological maturity of the reactors.

The SELENE project represents a significant step forward in lunar exploration, positioning Italy at the forefront of developing innovative solutions for sustainable human activities on the Moon. By providing a reliable and continuous energy source, the project aims to overcome the limitations of current technologies and pave the way for permanent lunar bases.

In addition to its implications for space exploration, the technologies and solutions developed through SELENE have the potential to impact various sectors on Earth. Advancements in sensor technology, automation, and wireless power transmission could find applications in industries ranging from energy to telecommunications.

The collaboration between ASI, ENEA, academic institutions, and industry partners underscores the multidisciplinary approach required for such a complex endeavor. This partnership leverages Italy's expertise in nuclear technology, aerospace engineering, and sustainable energy solutions, contributing to the nation's growing prominence in the global space sector.

As the project progresses, it is expected to attract international interest and collaboration, further solidifying Italy's role in the next era of space exploration. The successful implementation of the SELENE project could serve as a model for future initiatives aimed at establishing human presence on other celestial bodies, such as Mars.

In conclusion, the SELENE project embodies Italy's commitment to advancing space exploration through innovative and sustainable solutions. By developing small nuclear reactors to provide continuous energy on the Moon, Italy is addressing one of the critical challenges of establishing permanent human settlements beyond Earth. The project's success could have far-reaching implications, not only for lunar exploration but also for technological advancements on Earth.
