Shear properties of LHS-1 and LMS-1 Lunar regolith simulants

Kexin Yin et al.

Summary: This study reports the shear characterization of two new Lunar regolith simulants named LHS-1 and LMS-1. The results show that the shear properties of LHS-1 and LMS-1 are similar to actual Lunar regolith and other existing simulants. Additionally, the interfacial shear behavior of the two Lunar simulants at both peak and residual conditions was investigated.

Geomechanical properties of lunar regolith simulants LHS-1 and LMS-1

Jared M. Long-Fox et al.

Summary: The geomechanical properties of mineralogically accurate lunar regolith simulants LHS-1 and LMS-1 are quantified and compared. Results show that LHS-1 and LMS-1 are suitable for terrestrial studies in the absence of actual lunar regolith and are preferable to non-mineralogically accurate simulants. Their mineralogy-based design provides a good approximation of lunar regolith geochemistry and geomechanics, making them suitable for various research purposes.

The Potential for Lunar and Martian Regolith Simulants to Sustain Plant Growth: A Multidisciplinary Overview

Luigi Giuseppe Duri et al.

Summary: Bioregenerative life support systems (BLSS) and in situ resource utilization (ISRU) can combine to enable sustainable food production on the Moon and Mars, yet face numerous challenges. Space research studies use regolith simulants to replicate the physicochemical properties of extraterrestrial regoliths, exploring strategies such as amending simulants with organic wastes to enhance their suitability as life-sustaining substrates.

Materials characterization of various lunar regolith simulants for use in geopolymer lunar concrete

Peter J. Collins et al.

Summary: This study characterized five different lunar regolith simulants in detail and used the data to create geopolymer concrete samples for testing and analysis. The results showed that these simulant samples are feasible for concrete technology, but their performance varies due to differences in their mineralogy, amorphous content, and particle size and shape distributions.

Thermophysical properties of the regolith on the lunar far side revealed by the in situ temperature probing of the Chang'E-4 mission

Xiao Xiao et al.

Summary: By utilizing temperature probes onboard the Chang'E-4 spacecraft, scientists have obtained the first in situ regolith temperature measurements from the far side of the Moon. The data reveals the particle size, thermal conductivity, and bulk density of the lunar regolith, providing crucial information for future analysis and interpretation of global temperature observations.
