Simulant Name: MLS-2
Availability: Not Available
Fidelity: Standard
Developed By: University of Minnesota
Available From: N/A
Publications: Weiblen, P. W., and K. Gordon (1988), Characteristics of a Simulant for Lunar Surface Materials. Second Conference on Lunar Bases and Space Activities of the 21st Century, p.254.

MLS-2 was developed as a highlands simulant by grinding up an anorthosite from the Duluth Gabbro Complex. As with MLS-1/1P, there is little data available for this simulant and it is probably no longer available. Some sources state that only small quantities were made as a prototype.
