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 ...

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]

, 2010
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 ...

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

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 ...

Geomorphology, Mineralogy, and Geochronology of Mare Basalts and Non-Mare Materials around the Lunar Crisium Basin

Remote Sensing, 2021
The Nectarian-aged Crisium basin exhibits an extremely thin crust and complicated lunar geological history. This large multi-ring impact basin is characterized by prolonged lunar volcanism ranging from the Imbrian age to the Eratosthenian period, forming

Noble gases and nitrogen in material from asteroid Bennu

Meteoritics &Planetary Science, EarlyView.
Abstract We report the elemental and isotopic abundances of all stable noble gases (helium, neon, argon, krypton, and xenon) in eight particles from asteroid Bennu returned by NASA's OSIRIS‐REx mission. We also report nitrogen abundances and isotopic ratios that were analyzed alongside neon and argon in four additional Bennu particles.

Lithologic Mapping of HED Terrains on Vesta using Dawn Framing Camera Color Data

, 2013
The surface composition of Vesta, the most massive intact basaltic object in the asteroid belt, is interesting because it provides us with an insight into magmatic differentiation of planetesimals that eventually coalesced to form the terrestrial planets.

Microspherules Formed by Lightning Strikes

Meteoritics &Planetary Science, EarlyView.
Abstract Natural microspherules are formed by high‐temperature processes and are present throughout the geologic record to the present day. We report the discovery of large numbers of microspherules recovered from a rock pavement in the Pilbara region, Western Australia.

Development and characterization of a regional lunar soil simulant for emirates lunar missions

International Journal of Mining Science and Technology
Lunar soil simulants (LSS) have been pivotal in the success of past and current lunar missions. They have enhanced the design of lander and rover wheels through interaction studies on the lunar testbed under simulated environmental conditions.
