Spectral-Kinetic Synergy in Au-Network Engineered FeTiO<sub>3</sub>: A Multi-Field Coupling Strategy for Lunar In Situ Resource Utilization. [PDF]

open access: yesAdv Sci (Weinh)
How can humanity achieve lunar self‐sufficiency? We utilize Au topology networks to modify the abundant lunar ilmenite. This catalyst, under sunlight, can convert waste carbon dioxide into space fuel. This design leverages the moon's natural vacuum for green manufacturing, avoiding the waste of gold and serving as “artificial chloroplasts” to sustain ...

A petrological, mineralogical and chemical analysis of the lunar mare basalt meteorites LaPaz Icefield 02205, 02224 and 02226 [PDF]

open access: yes, 2006
LaPaz Icefield (LAP) 02205, 02226, and 02224 are paired stones of a crystalline basaltic lunar meteorite with a low-Ti (3.21–3.43% TiO2) low-Al (9.93–10.45% Al2O3), and low-K (0.11–0.12% K2O) composition.

Use of orbiting reflectors to decrease the technological challenges of surviving the lunar night [PDF]

open access: yes, 2011
In this paper the feasibility of using lunar reflectors to decrease the technological challenges of surviving the lunar night is investigated. This is achieved by attempting to find orbits in the two-body problem where the argument of periapsis is ...

Lunar meteorite regolith breccias: an in situ study of impact melt composition using LA-ICP-MS with implications for the composition of the lunar crust [PDF]

open access: yes, 2007
Dar al Gani (DaG) 400, Meteorite Hills (MET) 01210, Pecora Escarpment (PCA) 02007, and MacAlpine Hills (MAC) 88104/88105 are lunar regolith breccia meteorites that provide sampling of the lunar surface from regions of the Moon that were not visited by ...

Color Differences on the Lunar Surface [PDF]

open access: yes, 1968
Both a detailed literature survey and a new observational study were performed to determine and extend the knowledge of spectral reflectivity differences (color differences) on the lunar surface in the extended visible wavelength region.

A 3D hybrid simulation study of the electromagnetic field distributions in the lunar wake [PDF]

open access: yes, 2011
As a consequence of its lack of a thick atmosphere and an ionosphere, the interaction of the solar wind with the Moon is characterized by the direct impact of the solar wind on its sunward hemisphere.

Analysis of the Direct Shear Test and Microstructure of the Lunar Soil Simulant Solidified by Sodium Silicate

open access: yesAdvances in Materials Science and Engineering, 2022
The lunar soil is an ideal building material for future lunar base construction. In order to improve the strength of lunar soil, basalt with similar composition to lunar soil was used to simulate lunar soil due to lack of real lunar soil, and the ...

Using Machine Learning for Lunar Mineralogy-I: Hyperspectral Imaging of Volcanic Samples

open access: yesUniverse
This study examines the mineral composition of volcanic samples similar to lunar materials, focusing on olivine and pyroxene. Using hyperspectral imaging (HSI) from 400 to 1000 nm, we created data cubes to analyze the reflectance characteristics of ...
