Two Lunar Mare Soil Simulants

Acta Geologica Sinica - English Edition, 2011
Abstract:Two new lunar mare soil simulants, NAO‐2 and NAO‐3, have been created in National Astronomical Observatories (NAO), Chinese Academy of Sciences. These two simulants were produced from low‐titanium basalt and high‐titanium basalt respectively. The chemical composition, mineralogy, particle size distribution, density, angle of internal friction,

CAS-1 lunar soil simulant

Advances in Space Research, 2009
Abstract Lunar soil simulant is a geochemical reproduction of lunar regolith, and is needed for lunar science and engineering researches. This paper describes a new lunar soil simulant, CAS-1, prepared by the Chinese Academy of Sciences, to support lunar orbiter, soft-landing mission and sample return missions of China’s Lunar Exploration Program ...

Production of lunar soil simulant in Turkey

2017 8th International Conference on Recent Advances in Space Technologies (RAST), 2017
It is obvious that lunar structures will be constructed on lunar surface, and that the materials to be used are only lunar soil. That is why lunar soils has to be investigated thoroughly as to its physical, chemical and mechanical properties. Unfortunately there is not enough lunar rock or soil brought to Earth for being able to run these analyses. For

Important Considerations for Lunar Soil Simulants

Earth and Space 2010, 2010
Lunar samples are not readily available for In-Situ Resource Utilization (ISRU) studies, necessary for preparations for a return to the Moon with landers, robots, and astronauts. Lunar soil simulants have been produced as substitutes for the real thing; BUT how good are they? JSC-1 and 1A were produced only to approximate the geotechnical properties of

Lunar soil simulants alter macrophage survival and function

Journal of Applied Toxicology, 2019
AbstractLunar 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, 2012
Tongji-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 ...

Properties of Lunar Soil Simulant JSC-1

Journal of Aerospace Engineering, 1995
With 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

Flowability of lunar soil simulant JSC-1a

Granular Matter, 2010
We 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°.
