JSC Mars-1 and -1A are spectral simulants that replicate the visible/near-infrared reflectance properties of dust-covered terrains on Mars. They were sourced from palagonitic tephra from the Pu’u Nene cinder cone between Mauna Loa and Mauna Kea in Hawaii. The simulants are composed mostly of amorphous palagonite, with nanophase oxides giving them their orangeish color.
JSC Mars-1(A) contains significant amounts of volatiles and organic material, which have both been cited as challenges in using it as a realistic regolith simulant for Mars.
When the original supply of JSC Mars-1 ran out, Orbitec received a grant to re-produce the simulant from the same source, naming it JSC Mars-1A. Sometime in 2017, Orbitec’s simulant website went offline and this simulant seems to be unavailable outside of NASA, although many researchers still have small supplies.
