Recent scientific breakthroughs have transformed our understanding of the Moon, moving beyond simple theories to solid, evidence-based insights.
For decades, the lunar mantle remained a mystery because early missions only retrieved crustal samples.
A landmark discovery highlights a significant hemispheric dichotomy: the Moon’s farside mantle is much drier than the nearside mantle.
This asymmetry suggests that the Moon’s interior is not a uniform sphere but is highly heterogeneous.
Research also confirms a 'mantle overturn' process, where dense materials sank while lighter ones rose, explaining the presence of iron-rich elements in volcanic regions.
Furthermore, gravity-based models indicate that the massive South Pole-Aitken impact likely excavated deep mantle material, potentially bringing it within reach for future explorers like the Artemis missions.
By analyzing these compositions, scientists are refining our knowledge of the 'giant-impact hypothesis' and the Moon's cooling history.
Far from being a static rock, the Moon is revealed as a geologically dynamic world with an Earth-like internal structure, including a solid inner core and a partially molten core-mantle boundary.
