Mars Regolith Simulant [MGS-1]:
This tube of gray/red material is engineered regolith to be chemically and mechanically identical to that of parts of planet Mars. Regolith is a mixture of dust, soil, broken rock and other organic materials. NASA uses this material to test their rovers' performance abilities on the planet and to determine how well crops can be grown on Mars.
Mars Global Simulant (MGS-1) is a mineralogical standard for basaltic soils on Mars, developed based on quantitative mineralogy from the MSL Curiosity rover. It is designed to replicate the Rocknest windblown soil, that is chemically similar to other basaltic soils at disparate landing sites and thus constitutes a “global” basaltic soil composition. MGS-1 is made by sourcing individual minerals, including a proper treatment of the X-ray amorphous component. This is in contrast to previous Mars simulants that were usually sourced from a single terrestrial deposit (basalt or palagonite).
