Lunar analog (JSC-1A)
Practical significance
Mare lunar regolith simulant.
Origin
The JSC-1A material was mined from a commercial cinder quarry at Merriam Crater, a volcanic cinder cone located in the San Francisco volcano field near Flagstaff, Arizona. The sample was produced to match the Apollo 14 sample 14163. No chemical processing was performed on the simulant.
