The LMS-1D Lunar Mare Dust Simulant has been developed by Exolith Lab for dust mitigation experiments and other applications where very fine dust is needed. LMS-1D is made of the same base material as LMS-1, our high-fidelity, mineral-based simulant appropriate for a generic or average mare location on the Moon. LMS-1 is also found on our website. 

The term regolith, is referring to the “dirt” layer covering solid rock on the moon’s surface, which is loose, heterogeneous, superficial deposits. Our regolith simulant, often referred to as just “simulant”, is synthesized from terrestrial materials to mimic the chemical, mechanical or engineering properties of the materials that one would find on the moon. This regolith layer on the Lunar Surface is harmful to human health, and detrimental to space hardware. This simulant allows for testing to prepare humans and space hardware for these hazards. 

The simulant is not made of a single terrestrial lithology, but accurately captures the texture of lunar regolith by combining both mineral and rock fragments (i.e., polymineralic grains) in accurate proportions. This dust simulant contains only particles finer than 30 μm.

Bulk Chemistry

This table shows the relative abundances of each element detected by X-ray fluorescence (XRF). The relative abundances of elements detected by XRF in geological samples are quantified as oxides. In the simulant, these elements are contained in the minerals described in the Mineralogy table above, and not necessarily in oxide form. These data are from the Hamilton Analytical Lab.
