Analysis of High Frequency Marsquake Swarms Informed by Deep Learning

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract NASA's InSight mission has provided an unprecedented snapshot of Mars' seismicity, despite data analysis challenges arising from low signal‐to‐noise ratios (SNR) and single‐station constraints. High frequency (HF) events—the most common type—were initially assumed to propagate through shallow crustal layers.

Formation of Asteroid (16) Psyche by a Giant Impact

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Asteroid (16) Psyche is the largest likely metal‐rich asteroid in the Solar System and the target of the NASA Psyche mission. The mission aims to determine whether the asteroid is the core of a differentiated planetesimal that lost its mantle via a giant impact.

Evaluating the Depth–Age Hypothesis for the Evolution of the Lunar Regolith

The Planetary Science Journal
Lunar regolith is the fractured rock layer covering most of the lunar surface. This rock is fractured into regolith primarily by repeated meteorite impacts over eons.

The New Space Race Era: The Exogeoheritage Challenge and Its Conservation

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract The escalating pace of space exploration has ushered in a new era reminiscent of the space race of the 1960s. However, the discourse on exogeoconservation—the protection of geological heritage—now demands a prominent place in decision‐making processes.

Sintering lunar regolith pellets: a comparison of four samples from Apollo 11, 15, and 16

Materials Today Advances
Lunar regolith sintering is proposed as a technique to produce consolidated objects on the lunar surface from locally sourced materials. Understanding the sintering behaviour of real lunar regolith is necessary to optimise this process, however, due to ...

Application of Finite Difference Method for determining lunar regolith diurnal temperature distribution

E3S Web of Conferences, 2018
This study was performed in order to verify viability of using finite difference method and proposed simple astrometrical model for modelling heat transfer in lunar regolith. The concept was examined by developing FD model of heat flow for upper 0,9 m of

Craters and Lunar Lua (Pits/Skylights) in Mare Tranquillitatis and Marius Hills Reveal Variations in Protolith Properties

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract We investigated the regolith parent rock (“protolith”) properties of Mare Tranquillitatis and Marius Hills on the Moon, utilizing lunar pit craters (“lua”) to contextualize observations of rock abundance and crater degradation. We discovered a significant difference in underlying materials: the region around the Tranquillitatis lua is ...

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.

Lunar Regolith Temperature Variation in the Rümker Region Based on the Real-Time Illumination

Remote Sensing, 2020
Chang’E-5 will be China’s first sample−return mission. The proposed landing site is at the late-Eratosthenian-aged Rümker region of the lunar nearside.

Simulations of Radiological Dose Quantities in Astronauts During Solar Energetic Particle Events Across Modern Space History

Space Weather, Volume 24, Issue 1, January 2026.
Abstract Solar Particle Events (SPEs) represent one of the most significant hazards to future crewed space missions. Accurate assessment of radiation doses received by astronauts during these events is essential for determining the shielding requirements in spacecraft and off‐planet shelter design.
