Martian Analog (MGS-1 M)

Practical significance

The MGS-1 analog is a mineralogical standard for basaltic soils on Mars, developed based on quantitative mineralogy from the MSL Curiosity rover.

Origin

The MGS-1 (Mars Global Simulant) is made by sourcing individual minerals, including a proper treatment of the X-ray amorphous component. It was developed by the University of Central Florida.

Particle size

The sample was processed at the Instituto de Cerámica y Vidrio (CSIC-ICV) to produce a narrow particle size distribution centered at 3-4 micrometers.
