Simulant Name: CSM-LHT-1 Lunar Highlands Type
Availability: Available
Fidelity: Standard
Developed By: Colorado School of Mines
Available From: In transition; contact Kevin Cannon for details.

The CSM-LHT-1 simulant has been developed by Colorado School of Mines as a highly affordable but also high-quality lunar highlands simulant appropriate for generic highlands terrains on the Moon, including the poles. It is made from a mix of anorthosite and mafic feedstocks. Unlike other recent highlands simulants that use Greenspar250 (an anorthosite with no particles >250 μm), CSM-LHT-1 has a correct particle size distribution that mimics Apollo soils. The ingredients are milled together at the same time, ensuring an exceptionally well-mixed and homogeneous final product.
