Permeability of JSC-1A: A lunar soil simulant

Icarus, 2011
Abstract The permeability of lunar soil simulant, JSC-1A, is measured over a range of bulk densities from 1550 to 2000 kg m−3. The corresponding viscous flow permeability is 1 × 10−12 m2 to 6.1 × 10−12 m2 for this bulk density range. Implications of these values on the contamination of regolith by rockets, on barrier/enhancement to bulk flow of ice ...

Engineering Properties of Lunar Soil Simulant JSC-1A

Journal of Aerospace Engineering, 2010
This 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.

Development of a High Fidelity Lunar Soil Simulant

AIP Conference Proceedings, 2008
As NASA prepares for the future exploration activities on the Moon, there is a growing need to develop higher fidelity lunar soil simulants that can accurately reproduce the properties and behavior of the lunar soil. One of the biggest limitations of current lunar soil simulants (such as JSC‐1A lunar regolith simulant), is the lack of particles that ...

Geotechnical Properties of JSC-1A Lunar Soil Simulant

Journal of Aerospace Engineering, 2010
For the success of planned missions to the moon in the near future, it is essential to have a thorough understanding of the geotechnical behavior of lunar soil. However, only a limited amount of information is available about geotechnical properties of lunar soils. In addition, the amount of lunar soils brought back to Earth is small.

Experimental Study of Hygroscopicity of Lunar Soil Simulant

Applied Mechanics and Materials, 2013
The lunar soil simulants using for vehicle-terramechanics research on the ground need to expose in air containing water molecules for a very long time. The influence of the engineering properties of lunar soil simulant caused by air moisture should be determined.

The Research on Lunar Soil Simulant Production System

Advanced Materials Research, 2011
Because the lunar soil is rarely, lunar soil simulant plays an important part in lunar exploration, development and utilization of lunar resources, to establish a lunar base research work. This paper presents a lunar soil simulant production system which is suitable for ground experiment of Lunar Exploration Project.

Geotechnical Behavior of JSC-1 Lunar Soil Simulant

Journal of Aerospace Engineering, 2000
To facilitate the modeling and simulation of lunar activities and natural processes, various lunar soil simulants have been created. In particular, Johnson Space Center Number One lunar soil simulant (JSC-1) has come into wide use by a variety of investigators.

Soil-Tool Interaction Theories as They Apply to Lunar Soil Simulant

Journal of Aerospace Engineering, 1995
With 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 ...

Experimental simulation of tensile behavior of lunar soil simulant JSC-1

Materials Science and Engineering: A, 2008
The return of humans to the Moon, which includes construction and infrastructure development remain a national priority for exploration of space. Thus, a thorough understanding of lunar soil properties for purposes of engineering design is required. In the past lunar soil (regolith) simulant JSC-1 has been widely used by investigators in feasibility ...
