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

GeoHealth, 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

Earth 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 ...

Ultralow-binder-content thermoplastic composites based on lunar soil simulant [PDF]

, 2020
In a recent study, we developed ultralow-binder-content (UBC) structural materials based on lunar soil simulant and thermoset binders. In the current research, we investigated thermoplastic binders.

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

Scientific 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 ...

Simulation of Drilling Temperature Rise in Frozen Soil of Lunar Polar Region Based on Discrete Element Theory

Aerospace, 2023
As the frozen soil in the South Pole region of the Moon is an important water resource, the operation of drilling and retrieving samples of the frozen soil in this region will be a crucial task for us to accomplish in future deep-space exploration. Thus,

Strongly cohesive lunar soil identified at the Chang’e-6 landing site

Nature Astronomy
The physical properties of lunar soil are critical to understanding its evolution. However, the extent of the diversity among the global lunar soils remains unclear owing to limited sampling sites.

Plants grown in Apollo lunar regolith present stress-associated transcriptomes that inform prospects for lunar exploration

Communications Biology, 2022
Arabidopsis plants were seeded onto lunar soil samples taken directly from the Apollo 11, 12, and 17 missions. Transcriptomic analyses reveal that plants grown in lunar soil differentially express genes associated with salt, metal, and ROS stress.
