Soil-Tool Interaction Theories as They Apply to Lunar Soil Simulant
Journal of Aerospace Engineering, 1995With the establishment of a lunar base, excavation of the lunar soil will be a necessary and time-critical activity. It is the intent of this paper to establish the importance of certain excavation parameters and how they interrelate. With this approach, an overall efficiency of an excavating system can be determined and used as a basis for comparing ...

DEM parameter matching of high-dense lunar soil simulant
2015 IEEE International Conference on Information and Automation, 2015Discrete element method (DEM) is getting a wider use in granular media study. It is a fundamental of lunar soil DEM study that matching the micromechanical parameters of lunar soil simulant with its macro parameters. In this paper, the matching work is carried out by simulating triaxial test applying PFC3D software, and the constitutive model is a ...

An Organic‐Inorganic Nanohybrid Based on Lunar Soil Simulant
Advanced Engineering Materials, 2007One of the long term goals of sending human beings to the Moon and the Mars is to stay there, for which temporary outposts and permanent bases must be constructed. Due to the tight constraint of space transportation capacity, it is highly desirable that the outposts and bases can be built by using locally harvestable resources, such as lunar soils. For

Investigation and simulation of metallic spherules from lunar soils
Geochimica et Cosmochimica Acta, 1975The microstructure and chemical composition of metallic spherules from the lunar soil were studied by optical, electron-probe, and scanning-electron-microscope techniques. Metallic spherules produced experimentally were compared to the lunar spherules with respect to structure, chemistry, and cooling rates.

Engineering Properties of Lunar Soil Simulant JSC-1A
Journal of Aerospace Engineering, 2010This study was carried out to assess the tensile and shear strength in lunar soil, and to examine the variation as a function of density and confinement. Geotechnical engineering properties of the lunar soil simulant designated Johnson Space Center Number One-A lunar soil simulant (JSC-1A) have been investigated experimentally.

Experimental Research on Drilling and Sampling of Lunar Soil Simulant
Applied Mechanics and Materials, 2012China is conducting a lunar exploration mission named “Chang’e project”. The goal of the exploration mission is to obtain the drilling core without breaking the original geological information. Since the characteristics of drilling object in lunar exploration mission are different from the soil on the earth, efforts should be greatly made on special ...
