Bulk Chemistry

Because MGS-1C is a mineralogical standard, the bulk chemistry of simulants created from the standard will differ depending on the crystal chemistry of the source minerals used. Below, we report the latest analysis for the production version of MGS-1C.

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.
