Mojave Mars Simulant

We exclusively supply Mojave Mars Simulant, developed by NASA and the Jet Propulsion Laboratory (JPL) in 2007 for use while testing the Mars Phoenix lander.


No Martian soil - also known as "Regolith" - has ever been returned to Earth. In order to develop the technology and skills necessary to explore the red planet, NASA and JPL scientists have identified sources of material here on Earth that closely mimics the surface of Mars.

MMS is based on Saddleback Basalt, an iron-rich basalt from an ancient volcano in the Mojave desert of California. MMS is produced by crushing Saddleback basalt into sand, gravel and dust sizes. These grades are sorted by size then mixed to closely match the makeup of the Martian surface. 

We only use the same supplies identified by the JPL in developing our Mojave Mars Simulant. Our house blends (MMS-2 and MMS-2+) use the same material as a base and laboratory-grade reagents. This ensures that you only receive research-grade Mars regolith simulant.
