Dynamics of regolith dunes on small planetary bodies [PDF]

open access: yesEPJ 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.

Analysis of lunar regolith thermal energy storage [PDF]

open access: yes
The concept of using lunar regolith as a thermal energy storage medium was evaluated. The concept was examined by mathematically modeling the absorption and transfer of heat by the lunar regolith. Regolith thermal and physical properties were established

Silicate and Carbonate Weathering Perturbation at the Eocene‐Oligocene Transition Recorded by Mg Isotopes

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract During the Eocene‐Oligocene Transition (ca. 34 Ma), the Earth underwent a dramatic decline in atmospheric CO2, global cooling, a deepening of the carbonate compensation depth (CCD), and the formation of a permanent ice sheet on Antarctica. The expansion of Antarctic glaciers eroded the underlying bedrock and increased the weathering flux to ...

VELOX – A Demonstration Facilility for Lunar Oxygen Extraction in a Laboratory Environment [PDF]

open access: yes, 2010
The ultimate goal of a permanent human presence on the Moon is discussed intensively within the global lunar community. Obviously, such an effort poses stringent demands not only on the technology but also on logistics, especially considering the ...

Ozone Production by Electron Irradiation of Regolith Ice: Laboratory Study for the Icy Moons

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract We irradiate fine‐grained regolith pure water ice in ultra high vacuum with 5keV $5\,\text{keV}$ and 10keV $10\,\text{keV}$ electrons to study the radiolysis of water ice. The ice regolith is designed to closely mimic the physical characteristics of the surfaces of the icy moons of the Solar System.

On the Possibility of Melting Water Ice During the Recent Past of Mars: Implications for the Formation of Gullies

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract The formation of gullies on Mars has often been attributed to the melting of (sub)surface water ice. However, melting‐based hypotheses generally overlook key processes: (a) sublimation cooling by latent heat absorption, (b) the non‐stability of ice where melting conditions can be reached, and (c) the particular microclimates of gullied slopes.

Tackling Small Lunar Impact Crater Classification: A Novel Augmented Data Set and Enhanced Deep Learning Framework

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Small lunar impact craters, exhibiting diverse morphological characteristics, represent the most abundant geological features on the Moon's surface. These structures serve as crucial indicators for understanding regolith thickness distribution and surface modification processes.

Structural Analysis of Lunar Regolith from LPR CH-2 Data Based on Adaptive f-x E MD: LPR Data Processed by Adaptive f-x EMD

open access: yesAdvances in Astronomy, 2019
The Lunar Penetrating Radar (LPR) is one of the important scientific payloads in China’s Chang’E-3 (CE-3) to image within 100 m below the lunar surface. The acquired LPR data is significant for the research of lunar geological structure.

Regolith thermal energy storage for lunar nighttime power [PDF]

open access: yes
A scheme for providing nighttime electric power to a lunar base is described. This scheme stores thermal energy in a pile of regolith. Any such scheme must somehow improve on the poor thermal conductivity of lunar regolith in vacuum. Two previous schemes
