Behaviors of lunar regolith simulants under varying gravitational conditions

npj Microgravity
Understanding the behavior of regolith in varying gravity conditions, is critical for space exploration and future missions. In this work, the gravity-driven hopper flow of lunar regolith simulant in different gravitational accelerations (terrestrial ...

Artificial Space Weathering to Mimic Solar Wind Enhances the Toxicity of Lunar Dust Simulants in Human Lung Cells

GeoHealth
During NASA's Apollo missions, inhalation of dust particles from lunar regolith was identified as a potential occupational hazard for astronauts. These fine particles adhered tightly to spacesuits and were unavoidably brought into the living areas of the

Cohesion and shear strength of compacted lunar and Martian regolith simulants

Icarus
Shear strength and cohesion of granular materials are important geotechnical properties that play a crucial role in the stability and behavior of lunar and Martian regolith, as well as their terrestrial analog materials. To characterize and predict shear strength and cohesion for future space missions, it is also important to understand the effects of ...

Circularly Polarized Lunar Regolith Simulant Antenna for Future Lunar Communication

Circularly Polarized Lunar Regolith Simulant Antenna for Future Lunar Communication
Our work investigates a new circularly polarized antenna using lunar regolith simulant substrates. Utilizing cement, water, and lunar regolith simulant in a particular volume composition, a lunar regolith simulant substrate is fabricated. This research delivers the measurement and construction of a single CP antenna in addition to the fabrication ...

Robotic drilling tests in simulated lunar regolith environment

Journal of Field Robotics, 2021
AbstractA deep extraterrestrial drilling mission potentially adds a new level of complexity, and it is crucial to understand the associated challenges. To cope with China's Chang'E 5 mission to return subsurface regolith samples from the Moon, a series of laboratory tests were performed to validate the lunar robotic drilling from 2015 to 2018.

Turkish Lunar Regolith Simulant TBG-1

Earth and Space 2022, 2023
Being terrestrial for so many thousands of years, humanity is now advancing in the direction of being extraterrestrial. Attempts made until now were quite promising, like walking on the Moon, living in stations for very long durations miles away from Earth, sending probes to unimaginable distances in space and bringing them back to Earth, etc.
