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.
