Simulant Name: UC Mars1
Current Status: Continued development
Developed By: University of Canterbury

UC Mars1 was developed recently at the University of Canterbury to test ISRU technology, and was based on the bulk chemistry of the Gusev Crater regolith near the Columbia Hills. Various rocks were sampled in the Banks Peninsula in the South Island of New Zealand, and the final mixture for the simulant consisted of 46% basalt, 37% washed basalt, 7% volcanic glass, and 9% washed volcanic glass. Washing was done to remove excess dust.

Scott et al. (2017) describe the production and basic properties of the simulant, and claim that the current production methods would allow for 30 kg/hr to be manufactured. Larger scale production and use as a construction material are planned for the future.
