SHPB tests and analysis of lunar soil simulant under different negative temperatures and water contents

open access: yes矿业科学学报, 2023
In order to study the dynamic mechanical properties of the frozen lunar soil in the permanent shadow area of the moon, the basaltic lunar soil simulant was used as the research object, and the dynamic impact test was performed on it.

Assessing Toxicity and Nuclear and Mitochondrial DNA Damage Caused by Exposure of Mammalian Cells to Lunar Regolith Simulants

open access: yesGeoHealth, 2018
Previous missions to the lunar surface implicated potential dangers of lunar soil. In future explorations, astronauts may spend weeks or months on the Moon, increasing the risk of inhaling lunar dust.

Mapping of the lunar surface by average atomic number based on positron annihilation radiation from Chang’e-1

open access: yesEarth and Planetary Physics, 2018
A map of the average atomic number of lunar rock and soil can be used to differentiate lithology and soil type on the lunar surface. This paper establishes a linear relationship between the average atomic number of lunar rock or soil and the flux of ...

Laser melting manufacturing of large elements of lunar regolith simulant for paving on the Moon

open access: yesScientific Reports, 2023
The next steps for the expansion of the human presence in the solar system will be taken on the Moon. However, due to the low lunar gravity, the suspended dust generated when lunar rovers move across the lunar soil is a significant risk for lunar ...
