Borehole reinforcement based on polymer materials induced by liquid-gas phase transition in simulating lunar coring

International Journal of Mining Science and Technology
Lunar core samples are the key materials for accurately assessing and developing lunar resources. However, the difficulty of maintaining borehole stability in the lunar coring process limits the depth of lunar coring.

Controlled Source DAS Coupling Tests: Implications for Unburied Deployment on the Moon and Earth

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract Moonquake recordings are key to understanding the Moon's internal structure, yet existing data from the Apollo missions are limited. Distributed Acoustic Sensing (DAS) offers a promising alternative to conventional seismometers for future lunar seismic monitoring, particularly due to its robustness and suitability for high‐scattering ...

Calibration of discrete element method simulation parameters for lunar rover using simulated lunar soil

Journal of Physics: Conference Series
Abstract To ensure the accuracy and scientific validity of simulation results in discrete element simulation of simulated lunar soil and sieve wheels for lunar surface probes, a method for calibrating the simulation parameters of an analog lunar soil simulation using a box-Behnken experimental design is proposed.

Experimental Hypervelocity Dust Impacts in Olivine—Multiscale Insights Into Microcrater Shock and Melting Effects From Coordinated SEM/TEM Observations

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract The flux of solar system meteoroids is dominated by objects less than 1 mm in diameter whose impact effects play a major role in the space weathering of airless body surfaces. These effects remain poorly characterized with respect to their dependence on the range of impact speeds for meteoroids across the inner solar system.

Simplified Particle Models and Properties Analysis Designed for DEM Lunar Soil Simulants

Aerospace
The discrete element method (DEM) is one of the most popular methods for simulating lunar soil simulants due to the lack of real lunar soil. To reduce the computational consumption and difficulty because of complex particle models, simplified particle ...

Assessing Potential Landing Sites With Favorable Illumination and Accessible, Potentially Volatile‐Rich Permanently Shadowed Regions Within Artemis Candidate Landing Regions

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract The lunar south pole features permanently shadowed regions (PSRs) that never receive direct sunlight. These regions maintain cold temperatures that potentially trap and accumulate volatiles over geologic timescales. Within NASA's Artemis candidate landing regions, we identified 130 candidate landing sites (CLSs) that satisfy the Human Landing ...

Fiber pulling apparatus modification [PDF]

A reduced gravity fiber pulling apparatus (FPA) was constructed in order to study the effects of gravity on glass fiber formation. The apparatus was specifically designed and built for use on NASA's KC-135 aircraft.
