An ANGSA Study: Crystal Size Distributions of Ilmenite in Basalts From Apollo 17 Drive Tube 73002 Open
Double drive tubes 73002 (upper) and 73001 (lower) were collected during Apollo 17 from a landslide deposit at the base of the South Massif in the Taurus‐Littrow valley. The drive tubes were opened for the first time as part of the Apollo …

The case for continuing VIPER - a critical milestone on the journey back to the Moon Open
NASA's VIPER mission was designed to explore the Moon's south pole region, with a primary objective of identifying and characterising volatile compounds such as water ice. Despite having been fully built and having passed all preflight env…

Textural coarsening as the cause for impact‐melt like plagioclase crystal size distributions and subtle layering in high‐Al basalt 14053 Open
High‐Al Apollo 14 basalt 14053 has been identified as an endogenous partial melt product from the lunar interior based on geochemical analyses, specifically low abundances of highly siderophile elements, but exhibits textural characteristi…

Revealing the Moon's Taurus‐Littrow Landslide via Integrated Analysis of Pristine Apollo 17 Soil Core 73001/2 Open
The “light mantle” deposit at the base of South Massif in the Moon's Taurus‐Littrow Valley was a primary science target for the Apollo 17 exploration. The possibility that it was a landslide triggered by ejecta from Tycho Crater is critica…

A lunar core dynamo limited to the Moon’s first ~140 million years Open
Single crystal paleointensity (SCP) reveals that the Moon lacked a long-lived core dynamo, though mysteries remain. An episodic dynamo, seemingly recorded by some Apollo basalts, is temporally and energetically problematic. We evaluate thi…

Constraining the formation and transport of lunar impact glasses using the ages and chemical compositions of Chang’e-5 glass beads Open
Impact glasses found in lunar soils provide a possible window into the impact history of the inner solar system. However, their use for precise reconstruction of this history is limited by an incomplete understanding of the physical mechan…

Absence of a long-lived lunar paleomagnetosphere Open
The Moon lacked a long-lived magnetic field of internal origin, and this allowed solar wind volatiles to accumulate in its soils.
