Thermal Properties of Lunar Regolith Simulants [PDF]

open access: yesEarth and Space 2010, 2010
Various high temperature chemical processes have been developed to extract oxygen and metals from lunar regolith. These processes are tested using terrestrial analogues of the regolith. But all practical terrestrial analogs contain H2O and/or OH-, the presence of which has substantial impact on important system behaviors.

Magnetic field coupling with lunar soil simulants

open access: yesScientific Reports, 2023
Wireless power transfer (WPT) using magnetically coupled resonators is being integrated into space vehicles destined for the lunar surface. The dusty soil on the Moon, called lunar regolith, is known to adhere to surfaces and is also known to contain ...

Interactions of rare earth elements with living organisms and emerging biotechnical applications

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Rare earth elements (REEs) are critical resources required to achieve net‐zero carbon emission targets and energy security. However, rising demand for REEs coupled with significant extraction and processing challenges and geopolitical risks restricts access to REE resources.

A Study Demonstrating That Using Gravitational Offset to Prepare Extraterrestrial Mobility Missions Is Misleading

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Recently, there has been a surge of international interest in extraterrestrial exploration targeting the Moon, Mars, the moons of Mars, and various asteroids. This contribution discusses how current state‐of‐the‐art Earth‐based testing for designing rovers and landers for these missions currently leads to overly optimistic conclusions about ...

Mechanical Characteristics of Lunar Regolith Drilling and Coring and Its Crawling Phenomenon: Analysis and Validation

open access: yesAerospace, 2022
The collection of lunar regolith with complete stratigraphic information is the key to analyzing the evolution and composition of the moon. To keep each sample’s stratification for further analysis, a sampling method called flexible-tube coring has been ...

Balancing Strength and Extreme Thermal Resilience in Lunar Regolith Composites: The Role of Multi‐Walled Carbon Nanotubes

open access: yesSmall, EarlyView.
This study investigates the impact of MWCNT reinforcement on the compressive strength of lunar regolith composites under varied curing conditions, including ambient with and without cycling and vacuum with cycling. Utilizing experimental methodologies, it identifies significant relationships between MWCNT content, curing protocols, and thermal cycling,
