Mars Global Simulant (MGS-1) is a mineralogical standard analog based on data collected from the Mars Science Laboratory Curiosity rover. MGS-1 is made by sourcing a spectrum of terrestrial minerals, then mixed together in specific proportions to generally replicate the Martian surface. This is in contrast to previous Mars simulants that were typically sourced from a single terrestrial deposit (basalt or palagonite).
Modified versions include MGS-1S Sulfate ISRU and MGS-1C Clay ISRU, specifically designed for water extraction applications. The root MGS-1 simulant is appropriate to test water extraction from bulk regolith.
All of our Martian simulants are a high-fidelity alternative to the more commonly known JSC MARS-1.
