Near- Earth Asteroids (NEAs) are an increasing area of study in the scientific community and growing space industry. NEAs present multiple reasons for closer examination, including resource extraction, investigating the presence of ingredients to life, early solar system composition, and planetary defense. …

Power cycles utilizing molten salt as a heat source have garnered significant interest due to their compatibility with next-generation molten salt reactors (MSRs), which provide inherent safety and compact design advantages compared to traditional light-water reactors. With the initiation of projects aimed …

For sustained lunar surface operations, high-temperature thermal management systems are essential to support nuclear power cycles, especially those that can utilize in-situ thorium resources available on moon. In this study, two key aspects are addressed: the design of a tungsten–lithium heat pipe …
