Computational Analysis of the Vibrational Response of Lunar Regolith Made of Nonspherical Grains

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Vibration‐based systems have shown that appropriately oriented and tuned mechanical oscillations can disrupt regolith interlocking and promote flow. Building on this evidence, the present study investigates vibration‐controlled granular discharge as a potential ISRU (In Situ Resource Utilization) strategy, with the aim of supporting ...

On Modeling Drilling Load in Lunar Regolith Simulant [PDF]

Chinese Journal of Mechanical Engineering, 2018
Drilling and coring, as effective ways to obtain lunar regolith along the longitudinal direction, are widely applied in the lunar sampling field. Conventionally, modeling of drill-soil interaction was divided into soil cutting and screw conveyance processes, ignoring the differences in soil mechanical properties between them.

Hexapod Locomotion Across Structured and Unstructured Terrains: A Data‐Driven Review of Modeling, Control, and Validation

Journal of Field Robotics, EarlyView.
ABSTRACT The design of a hexapod is complex and requires integration between kinematic models, control systems, and sensing. Existing literature has reviewed these sub‐systems in isolation. Since 2021, there has been no review of the field despite significant advancements in soft soil, lunar traversal, and artificial intelligence.

Magnetic field coupling with lunar soil simulants

Scientific Reports, 2023
Wireless power transfer (WPT) using magnetically coupled resonators is being integrated into space vehicles destined for the lunar surface. The dusty soil on the Moon, called lunar regolith, is known to adhere to surfaces and is also known to contain ...

Effects of Ambient Moisture and Large‐Strain Dynamic Preloading on the Dynamic Properties of the EAC‐1A Regolith Simulant

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 16, Page 5701-5711, November 2026.
ABSTRACT The EAC‐1A lunar mare simulant, a silty sand, was selected by the European Astronaut Center (EAC) for use in the LUNA analogue facility's lunar simulation testbed. Its stress‐ and strain‐dependent shear modulus and damping ratio were determined via resonant column testing on specimens prepared either from ambient moisture material or oven ...

Dust Plumes Induced by a Time‐Varying Electron Beam

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract We present laboratory results to address dust charging and lofting on the Moon and other airless planetary bodies in response to time‐varying solar wind and ultraviolet (UV) exposure. In these experiments, dust is exposed to an electron beam that varies in beam energy between 40 and 260 eV as a function of time.

Meter‐Scale Lunar Dust‐Bed Charging and Local Apparent Dust Release Under Ultraviolet Irradiation

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Vacuum ultraviolet (VUV) irradiation charges lunar regolith and may contribute to electrostatic dust mobilization, but meter‐scale laboratory constraints remain limited. We developed a meter‐scale deuterium‐lamp‐array VUV system that combines optical‐path superposition and stable array stitching to produce a controlled lunar‐relevant photon ...
