Rock Grinding

Detailed Description

Rocks from the Stillwater Mine are brought to the USGS in Denver, Colorado, where they are sledged and ground before entering the plasma melter at Zybek Advanced Products.
The USGS has created man-made moon dirt, or regolith, to help NASA prepare for upcoming moon explorations. Four tons of the simulant is expected to be made by this summer of 2009 and turned over to the scientific community involved in lunar exploration.
