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,

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.

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 ...

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 ...

Optimising Camera Trap Surveys for the Rocky Landform Specialists of the Mount Isa Inlier, Queensland, Australia. [PDF]

Ecol Evol
This study details an extensive camera trap survey of rocky landform fauna in the Mount Isa Inlier, identifying species‐specific detectability patterns. Our findings inform a comprehensive reference table of optimal camera trap survey guidelines to improve survey efficiency for a poorly represented fauna inhabiting a remote, data‐deficient region ...

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.

An Empirical Model to Estimate Abundance of Nanophase Metallic Iron (npFe⁰) in Lunar Soils

Remote Sensing, 2020
Lunar soils gradually become mature when they are exposed to a space environment, and nanophase metallic iron (npFe0) generates within them. npFe0 significantly changes the optical properties of lunar soils and affects the interpretation of the remotely ...

Crater Observing Bioinspired Rolling Articulator (COBRA)

Advanced Intelligent Systems, EarlyView.
Crater Observing Bio‐inspired Rolling Articulator (COBRA) is a modular, snake‐inspired robot that addresses the mobility challenges of extraterrestrial exploration sites such as Shackleton Crater. Incorporating snake‐like gaits and tumbling locomotion, COBRA navigates both uneven surfaces and steep crater walls.
