High-Resolution Radar Studies of the Moon's Mega-Regolith

The Moon's surface is exposed to constant bombardment by meteorites, and over time these impacts create a mixed layer of pulverized dust and rock fragments called the regolith. In the relatively younger basalt flows that fill ancient basin floors, the regolith is a few meters thick. In older highlands terrain, the regolith is more complex, varying widely in thickness and in block size distribution. These changes across the highlands are linked with proximity to ma jor basin-forming impacts, which redistribute even kilometer-scale blocks over great distances. The highland "mega-regolith" is thus up to several km thick, comprised of small to very large fragments of excavated crust. Our goal is to understand spatial variations across the highlands through radar studies of the physical characteristics of debris from 1-km to 100's-km craters that probe the upper few meters to km of the mega-regolith.
