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.

A proposal of lunar long duration method (Fabrication of lunar environment simulator and experimental validation)

Nihon Kikai Gakkai ronbunshu, 2014
A lunar long duration method which utilizes a characteristic of a very low thermal conductivity of lunar regolith has been proposed. The principle of this method is to put heater in desired depth of the regolith and heat up the regolith layer during ...
