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 an upgraded, high-fidelity alternative to the more commonly known JSC MARS-1.

*Previous spec sheets and data for past regolith simulant batches can be found at bottom of page.
The mineralogy below is the most up-to-date, superseding that described in Cannon et al. 2019.
This table shows the relative abundances of each element detected by X-ray fluorescence (XRF). The relative abundances of elements detected by XRF in geological samples are quantified as oxides. In the simulant, these elements are contained in the minerals described in the Mineralogy table above, and not necessarily in oxide form. These data are from the Hamilton Analytical Lab.
