Here is where we post Regolith dusty ideas that aren't ready for prime time, ie, published on the front side of this page.

for instance, I know lith means stone but what's a Rego?

According to Wikipedia:

Regolith (Greek: Ρηγόλιθος) is a layer of loose, heterogeneous material covering solid rock. The term is a combination of two Greek words: Rhegos (Greek: Ρήγος), which means blanket, and Lithos (Greek: Λίθος), which means rock. It includes dust, soil, broken rock, and other related materials and is present on Earth, the Moon, some asteroids, and other planets. The term was first defined by George P. Merrill in 1897 who stated, "In places this covering is made up of material originating through rock-weathering or plant growth in situ. In other instances it is of fragmental and more or less decomposed matter drifted by wind, water or ice from other sources. This entire mantle of unconsolidated material, whatever its nature or origin, it is proposed to call the regolith." <ref>Merrill, G. P. (1897) Rocks, rock-weathering and soils, New York: MacMillan Company, 411p.</ref>

• I like one definition of how Lunar regolith got there: "bedrock churned by meteorites." That gave me a vision of Luna suffering millenia of meteor strikes re-striking previous strikes, on and on forever, perpetual dart board of meteors.
