Soil mechanics on the Moon, Mars, and Mulberry [PDF]
From a soil mechanics point of view, the Moon is a relatively simple place. Without any water, organics, or clay minerals, the geotechnical properties of the lunar soil are confined to a fairly limited range.

Diatom-driven activation of in-situ lunar resource utilization for space farming
BiogeotechnicsIn this study, we demonstrate that diatoms, through their bioweathering process, can enhance the properties of lunar soil, thereby facilitating the cultivation of crops.

Thermochemical energy storage for a lunar base [PDF]
A thermochemical solar energy storage concept involving the reversible reaction CaO + H2O yields Ca(OH)2 is proposed as a power system element for a lunar base. The operation and components of such a system are described. The CaO/H2O system is capable of

An Astronaut's Risk of Experiencing a Critical Impact from Lunar Ejecta During Lunar EVA [PDF]
The Moon is under constant bombardment by meteoroids. When the meteoroid is large, the impact craters the surface, launching crater ejecta far from the impact potentially threatening astronauts on the lunar surface.
