Name: LMS-1 Lunar Mare Simulant

Team photo

The LMS-1 Lunar Mare Simulant has been developed by the CLASS Exolith Lab. It is a high-fidelity, mineral-based simulant appropriate for a generic or average mare location on the Moon. 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.

The particle size distribution of the simulant is targeted to match that of typical Apollo soils. LMS-1 does not currently simulate agglutinates or nanophase iron.
