FROST-Y is a frozen, volatile-bearing lunar simulant, part of the specialty ‘Y-series’ of simulants developed by the Exolith Lab. It is meant to represent volatile-bearing regolith found at the lunar poles in permanently shadowed regions.

By default, the 6.8% concentration of volatiles is based on the results of the LCROSS experiment that indicated 5.6 ±2.9 % water ice plus other sulfur- and carbon-bearing contaminants.
