Spec Sheet  SDS  Citation 

MGS-1S is a modified version of the root MGS-1 simulant, and is enriched in the polyhydrated sulfate gypsum. This represents the Reference Case “B” in the NASA Mars Water In-Situ Resource Utilization Study.

MGS-1S is specifically designed for ISRU water extraction studies; the M-WIP study concluded that polyhydrated sulfate deposits represent a clear advantage over bulk regolith or clay-bearing deposits in terms of mass and power, and may be much easier to access and excavate than permafrost deposits.
