Geology and Chronology of the Lunar Taruntius Crater: Implications for the Retention Age of Lunar Ray Patterns and Lifetime of Lunar Explosive Volcanism

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract The Taruntius crater, situated between Maria Fecunditatis, Crisium, and Tranquillitatis, is characterized by a prominent bright ray system and a floor‐fractured morphology and has long been interpreted as a relatively young Eratosthenian or Copernican crater.

Dynamics of regolith dunes on small planetary bodies [PDF]

EPJ Web of Conferences
The surfaces of small planetary bodies are covered with regolith which keeps evolving with time. Studying the dynamics of these regolith can explain various surface features observed in recent space explorations.

Seismic Velocity Variations Illustrate Hydrological and Ecohydrological Processes in a Mountain Watershed

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract We employ passive seismic interferometry to study seismic hydrological responses in a snowmelt‐driven, semi‐arid catchment. Seismic velocity changes (dv/v) at 2–4 Hz and 4–8 Hz are analyzed from six stations along a hillslope transect between May and November 2023 and compared to precipitation, soil moisture, and groundwater level timeseries ...

Radiation Exposure and Shielding Effects on the Lunar Surface

Space Weather
The Moon will be a primary target for human space exploration in the near future. A limiting factor for a crewed mission to the Moon is the radiation dose during their stay on the lunar surface.

Determination of the Dynamic Angle of Repose of Lunar Regolith Simulants

Geosciences
The determination of the dynamic angle of repose (DAR) of lunar regolith simulants is essential for modeling material behavior during in situ resource utilization (ISRU) processes and lunar surface operations.

Low Abundances of Ultramafic Components in the Chang'e‐6 Landing Site Basalt and Ejecta Material

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The South Pole‐Aitken (SPA) Basin, the Moon's largest impact structure, holds key insights into lunar evolution, prompting the Chang'e‐6 mission to return first samples for ground‐truth verification. Analysis of over 6,000 grains from the Chang'e‐6 soil returned from the SPA Basin reveals a composition dominated by clinopyroxene (26.5–32.9 vol.

Regolith in Motion: Dynamic Surface Evolution After Lunar Impacts

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Multi‐temporal observations captured by the Lunar Reconnaissance Orbiter Camera provide valuable insights into contemporary surface changes. These images reveal that minor impact events (resulting in <100‐m diameter craters) significantly alter regolith structure over great distances (>1,000 crater diameters) by increasing the meter‐to ...

Spirulina supported plant growth in regolith simulants and elevated levels of CO2

Frontiers in Space Technologies
IntroductionA key element for sustainable off-world habitation is the ability to grow food through in-situ resource utilization (ISRU). Growth substrates are required to overcome the challenges of ISRU in the space environment, including the use of ...

Investigating the Impact of the Spatially Heterogeneous Surface Dust Cover on Martian Global Dust Event Occurrence

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The observed inter‐annual variability of Global Dust Events (GDE) occurrence on Mars remains challenging to understand and therefore to predict. Several hypotheses have been investigated so far, but a central aspect seems to be missing: How the heterogeneity of the surface dust cover and regolith particle size distributions relate to regional ...
