Simulant Name: NEU-1 Northeastern University Lunar Simulant
Availability: May Be Available
Fidelity: Standard
Developed By: Northeaster University, Shenyang, China
Available From: N/A
Publications: Guan, J. et al. (2020), Preparation and characterization of Martian soil simulant NEU Mars-1. Trans. Nonferrous Met. Soc. China, 30, 212-222

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.
