Computer Modeling Suggests Deep Lunar Mantle Rocks Accessible at Artemis Landing Sites

New computer modeling indicates that some rocks at NASA's proposed Artemis landing zones near the Moon's south pole may originate from hundreds of miles beneath the lunar crust. This suggests that future astronauts could potentially collect samples from the Moon's deep interior, a region never before sampled, offering unprecedented insights into lunar geology.

Context

NASA's Artemis program aims to return humans to the Moon and establish a sustainable presence. The proposed landing sites near the Moon's south pole are of particular interest due to the presence of water ice and unique geological features. Previous lunar missions have primarily focused on surface samples, making the deep lunar mantle largely unexplored.

Why it matters

The potential to access deep lunar mantle rocks could significantly advance our understanding of the Moon's geological history and formation. This information may provide insights into planetary processes that are relevant not only to the Moon but also to other celestial bodies. Understanding the Moon's interior could also inform future exploration and resource utilization efforts.

Implications

If astronauts successfully collect samples from the deep lunar mantle, it could reshape scientific understanding of the Moon and its evolution. This could also influence future lunar missions and the design of exploration technologies. The findings may have broader implications for planetary science, affecting theories about the formation of terrestrial planets.

What to watch

As the Artemis program progresses, key developments will include the selection of specific landing sites and the technology needed for sample collection. Future missions may reveal more about the composition of the lunar mantle and how it relates to the Moon's overall geology. Observations from upcoming lunar missions could provide additional data to support these findings.
