Connecting Meteorite Spectra to Lunar Surface Composition Using Hyperspectral Imaging and Machine Learning

Universe
We present an innovative, cost-effective framework integrating laboratory Hyperspectral Imaging (HSI) of the Bechar 010 Lunar meteorite with ground-based lunar HSI and supervised Machine Learning (ML) to generate high-fidelity mineralogical maps.

MINERALOGICAL ANALYSIS OF LUNAR ROCK PARTICLES

Le Journal de Physique Colloques, 1976
Mössbauer measurements on 57Fe in a series of LUNA-16 and LUNA-20 coarsegrain (mostly containing two distinct minerals) as well as fine-grain rock fragments have been performed. The diameter of the particles ranges from 0.2 to 0.5 mm ; a device for their reproducible adjustment and centering has been developed.

Identification and quantification of minerals within Apollo samples using LWIR spectroscopy

Geo-spatial Information Science
The mineral composition of the lunar surface is a critical scientific objective, as it provides key insights into the evolution of the Moon. For instance, the variations in Mg-Fe composition of pyroxene solid solution could reveal the Moon’s crustal ...

LZS-1, Lanzarote (Canary Island, Spain) lunar (Apollo 14) basaltic soil simulant

Scientific Reports, 2022
The search for Terrestrial Analogues is essential for the development of future permanent or semi-permanent lunar bases. Terrestrial Analogues are zones where it is possible to probe not only scientific instruments, but also other astronaut capabilities ...

Constraining the Protoliths of the Apollo Granulite Suite

The Planetary Science Journal
The Apollo granulite suite represents the metamorphosed products of impact-contaminated polymict and monomict lunar breccias. We combine bulk and mineral major and trace element systematics with noble gas isotopes to constrain the highland lithologies ...

A Spectrophotometric Evaluation of Lunar Catharina Crater Using Support Vector Regression Analysis for FeO and TiO₂ Estimations [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Support Vector Regression (SVR) is an extended version of the Support Vector Machine (SVM) algorithm. It is an effective machine learning tool for handling huge complex data sets. SVR algorithm is introduced to the existing lunar FeO and TiO2 concentrate

Mineralogy of the lunar crust: Results from Clementine [PDF]

Meteoritics & Planetary Science, 1999
Abstract— The central peaks of 109 impact craters across the Moon are examined with Clementine ultraviolet‐visible (UVVIS) camera multispectral data. The craters range in diameter from 40 to 180 km and are believed to have exhumed material from 5–30 km beneath the surface to form the peaks, including both upper and lower crustal rocks depending on ...

Effects of Ambient Moisture and Large‐Strain Dynamic Preloading on the Dynamic Properties of the EAC‐1A Regolith Simulant

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT The EAC‐1A lunar mare simulant, a silty sand, was selected by the European Astronaut Center (EAC) for use in the LUNA analogue facility's lunar simulation testbed. Its stress‐ and strain‐dependent shear modulus and damping ratio were determined via resonant column testing on specimens prepared either from ambient moisture material or oven ...

Petrogenesis of Lunar Farside Highland Lithologies: Implications for Lunar Crust Formation

The Astrophysical Journal
The lunar soil samples collected by the Chang’e-6 (CE-6) mission provide a unique opportunity to study the composition and formation of the lunar crust on the farside of the Moon.

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

Journal of Field Robotics, EarlyView.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full
