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).
This simulant is commonly used by research institutes and organizations such as NASA, MIT, and Blue Origin for space hardware and ISRU testing. In addition, MGS-1 is used by many educational institutions for demonstrations on Martian Geology and experiments like extraterrestrial agriculture such as plant growth.
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.
