The regoliths developed on the Earth are producedby processes that are uniquely terrestrial—thepresence of oxygen, the influences of wind and water,and the activities of life. In contrast, on the airless,lifeless Moon, the lunar regolith results from uniquelydifferent processes—the continuous impact of largeand small meteoroids and the steady bombardment ofthe lunar surface by charged atomic particles from thesun and the stars

Many industrial Teflon coatings can withstand temperatures as low as -250ºF without loss of physical properties and can operate continuously at temperatures up to 260°C/500°F
