KLS-1 Korea Lunar Simulant
Simulant Name: KLS-1 Korea Lunar Simulant
Availability: May Be Available
Fidelity: Standard
Developed By: Korea Institute of Civil Engineering and Building Technology
Available From: N/A

KLS-1 is a low-Ti mare simulant developed at the Korea Institute of Civil Engineering and Building Technology. This simulant uses an instrusive basaltic material from Cheorwon, after sampling a number of basalts throughout Korea to choose the best one based on chemistry. Apollo 14 sample 14163 was used as a reference.
The raw basalt was powdered and sieved to a number of size fractions, then re-combined to achieve an accurate particle size distribution. Ryu et al. (2018) claim that this size distribution is more accurate than JSC-1 and FJS-1.
Ryu et al. also cite the cost effectiveness of KLS-1, and describe plans to scale up with capacities of 1 ton per 8 hours. It isn’t clear if KLS-1 is yet available to the community or what the timescale of production is.
