The origin of amino acids in lunar regolith samples

Geochimica et Cosmochimica Acta, 2016
AbstractWe analyzed the amino acid content of seven lunar regolith samples returned by the Apollo 16 and Apollo 17 missions and stored under NASA curation since collection using ultrahigh-performance liquid chromatography with fluorescence detection and time-of-flight mass spectrometry.

Magnetic Mineralogy in Lunar Mare Basalts and Implications for Paleointensity Retrieval

Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract Lunar paleomagnetic studies have identified multidomain metallic Fe–Ni alloys as the dominant magnetic contributors in mare basalts. Here, we explore the low‐temperature magnetic behavior of standard samples for a suite of opaque minerals that occur within mare basalts (single‐domain and multidomain Fe, wüstite, ulvöspinel, iron chromite ...

Investigation of the Thermal Conductivity of Dry and Icy Lunar Regolith Simulants

Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract This study investigates the thermal conductivity of lunar regolith simulants, both with and without the addition of ice. A novel icy regolith simulant was developed, combining microgranular water ice particles and lunar highlands simulant LHS‐1.

On the Crustal Architecture of the Terrestrial Planets

Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract Understanding the structure and composition of planetary crusts is fundamental for unraveling the diverse geologic pathways of rocky bodies in the solar system. In recent years, geophysical missions have shed light on the crustal architecture of the Moon and Mars.

A Compressive Sensing-Based Approach to Reconstructing Regolith Structure from Lunar Penetrating Radar Data at the Chang’E-3 Landing Site

Remote Sensing, 2018
Lunar Penetrating Radar (LPR) is one of the important scientific systems onboard the Yutu lunar rover for the purpose of detecting the lunar regolith and the subsurface geologic structures of the lunar regolith, providing the opportunity to map the ...

Enhanced Seismic Backscattering for Lava Tube Detection

Geophysical Research Letters, Volume 52, Issue 16, 28 August 2025.
Abstract Lava tubes, a common volcanic feature on terrestrial planets, offer critical insights into lava flow processes and may serve as future potential habitats for space crews and other facilities on the Moon and Mars. Seismic detection of these features is challenging as the irregular morphology and rough cave ceilings and walls generate complex ...

Planetary Soil Simulant Characterisation: NU-LHT-2M Study Case to Support Oxygen Extraction Lab Tests with a Low-Temperature Carbothermal Process

Aerospace
Since the landing on the lunar surface, the lunar regolith has begun to interact in different ways with landed elements, such as the wheels of a rover, astronaut suits, drills, and plants for extracting oxygen or manufacturing objects.

Impact of a Coronal Mass Ejection on the Lunar Exosphere as Observed by CHACE‐2 on the Chandrayaan‐2 Orbiter

Geophysical Research Letters, Volume 52, Issue 15, 16 August 2025.
Abstract The Moon encountered an extreme space weather event (NOAA G5 class) on 10 May 2024, caused by a series of coronal mass ejections (CMEs). Chandra's Atmospheric Composition Explorer‐2 (CHACE‐2), a neutral gas mass spectrometer on board Chandrayaan‐2 orbiter, made in situ observations of the lunar exosphere during this period.
