Investigation into failure mechanisms of lunar regolith simulant under thin-walled drilling tool with critical parameters

open access: yesInternational Journal of Mining Science and Technology
Acquiring pristine deep lunar regolith cores with appropriate drilling tools is crucial for deciphering the lunar geological history. Conventional thick-walled drill bits are inherently limited in obtaining deep lunar regolith samples, whereas thin ...

Regolith thermal energy storage for lunar nighttime power [PDF]

open access: yes
A scheme for providing nighttime electric power to a lunar base is described. This scheme stores thermal energy in a pile of regolith. Any such scheme must somehow improve on the poor thermal conductivity of lunar regolith in vacuum. Two previous schemes

Experimental Limit on the Cosmic Diffuse Ultra-high Energy Neutrino Flux

open access: yes, 2003
We report results from 120 hours of livetime with the Goldstone Lunar Ultra-high energy neutrino Experiment (GLUE). The experiment searches for = 100 EeV neutrinos in the lunar regolith.

Charging Properties and Particle Dynamics of Chang’e-5 Lunar Sample in an External Electric Field

open access: yesEngineering
Facing the challenges of in-situ utilization of lunar regolith resources, applying an external electric field to manipulate lunar particles has become a promising method for space particle control, which mainly depends on the particle charging properties

Analysis of regolith electromagnetic scattering as constrained by high resolution Earth-based measurements of the lunar microwave emission [PDF]

open access: yes
When high resolution measurements of the phase variation of the lunar disk center brightness temperature revealed that in situ regolith electrical losses were larger than those measured on returned samples by a factor of 1.5 to 2.0 at centimeter ...

Sustainable Human Presence on the Moon using In Situ Resources [PDF]

open access: yes, 2008
New capabilities, technologies and infrastructure must be developed to enable a sustained human presence on the moon and beyond. The key to having this permanent presence is the utilization of in situ resources.

Estimation of energy and material use of sintering-based construction for a lunar outpost - with the example of SinterHab module design [PDF]

open access: yes, 2015
In this paper, we would revisit the usability of microwave for lunar regolith sintering through an in-depth experiment, and examine the minimum materials and energy required for sintering based on the SinterHab design.
