Simulant Name: CSM-MGS-1C Mars Clay ISRU
Availability: Available
Fidelity: Standard
Developed By: Colorado School of Mines
Available From: Simulants at Mines
Publications: Cannon, K. M., D. T. Britt, T. M. Smith, R. F. Fritsche, and D. Batcheldor (2019), Mars Global Simulant MGS-1: A Rocknest-based Open Standard for Basaltic Martian Regolith Simulants. Icarus, 317, 470-478.

CSM-MGS-1C is a modified version of the root CSM-MGS-1 simulant, and is enriched in hydrated clay minerals (smectite). This represents the Reference Case “C” in the NASA Mars Water In-Situ Resource Utilization Study, led by Angel Abbud-Madrid of CSM.

MGS-1C is specifically designed for ISRU water extraction studies; the M-WIP study concluded that hydrated clay deposits are advantageous for water extraction on Mars, and may be much easier to access and excavate than permafrost deposits.

Refinement and testing are wrapping up before the simulant becomes more widely available for $3/kg.
