Simulant Name: MGS-1C Clay ISRU
Current Status: Available
Developed By: University of Central Florida
Available From: CLASS Exolith Lab
Spec Sheet: MGS-1C Spec Sheet
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.

MGS-1C is a modified version of the root 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.

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.

We are distributing MGS-1C through the CLASS Exolith Lab.
