Additive manufacturing of lunar regolith structures
Open Ceramics, 2021 The key to any presence in space being sustainable is the ability to manufacture the necessary structures and spares in situ and on-demand, in order to avoid the cost, volume, and up-mass constraints that would prohibit a successful launch with everything needed for long-duration and long-distance missions from Earth. In terms of meeting the demand for

Shear Properties of Lunar Regolith Simulants
Procedia Engineering, 2014 AbstractThe accuracy of lunar regolith simulants for lunar drilling and sampling is mainly based on their particle shape and grain size distribution. To determine the grain-size distribution and shear strength parameters, grain-size distribution tests and conventional tri-axial compression experiments were conducted on the lunar regolith simulants.

Regolith history of lunar meteorites [PDF]
Meteoritics & Planetary Science, 2005 The regolith evolution of the lunar meteorites Dhofar (Dho) 081, Northwest Africa (NWA) 032, NWA 482, NWA 773, Sayh al Uhaymir (SaU) 169, and Yamato (Y-) 981031 was investigated by measuring the light noble gases He, Ne, and Ar. The presence of trapped solar neon in Dho 081, NWA 773, and Y-981031 indicates an exposure at the lunar surface. A neon three-
