This simulant was prepared from iron-rich basalts of the Chahar volcanic group in Wulanchabu, Inner Mongolia. The basalt was dried, crushed and ball-milled then sieved to six size classes that were re-combined to create the desired particle size distribution. Magnetite and hematite were then added to the simulant as Fe and Ti oxides.
The main application of NEU Mars-1 is for testing oxygen and metal extraction for ISRU purposes.
It isn't clear how much simulant has been produced or what the availability is.
