Lunar soil simulants alter macrophage survival and function
Journal of Applied Toxicology, 2019AbstractLunar regolith samples collected during previous Apollo missions were found to contain components that were established to be toxic to humans; however, the health effects due to inhalation of lunar soil as a whole are still unknown. Macrophages residing in the alveolar sacs of the lungs constitute one of the last lines of defense against ...

Properties of TJ-1 Lunar Soil Simulant
Journal of Aerospace Engineering, 2012Tongji-1 lunar soil simulant (TJ-1 for short) was recently invented by Tongji University, China. It could be used to construct testing ground in the preparatory impact tests of lunar landers under the extremely adverse condition in the Earth environment, where the interaction pressure between lunar lander and lunar soil has the important effect on the ...

Development of a High Fidelity Lunar Soil Simulant
AIP Conference Proceedings, 2008As 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 ...

Permeability of JSC-1A: A lunar soil simulant
Icarus, 2011Abstract 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 ...

Experimental Study of Hygroscopicity of Lunar Soil Simulant
Applied Mechanics and Materials, 2013The 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.

Flowability of lunar soil simulant JSC-1a
Granular Matter, 2010We have done a complete flowability characterization of the lunar soil simulant, JSC-1a, following closely the ASTM-6773 standard for the Shulze ring shear test. The measurements, which involve pre-shearing the material before each yield point, show JSC-1a to be cohesionless, with an angle of internal friction near 40°.

Journal of Aerospace Engineering, 2015
AbstractThe exploration and development of space will require energy that is reliable, ubiquitous, and economical to produce. The international space station relies on photovoltaics to generate electricity stored in nickel-hydrogen batteries for powering the station during the “night”.

Properties of Lunar Soil Simulant JSC-1
Journal of Aerospace Engineering, 1995With the establishment of a lunar base, many tasks will require direct interaction between the in-situ lunar soil and a wide variety of instruments and implements. The individual tasks may be scientific in nature, or simply the manipulation of the lunar soil. To help fulfill the need for relatively large quantities of lunar soil simulant in researching

The Research on Lunar Soil Simulant Production System
Advanced Materials Research, 2011Because 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.
