Most of the sand on the Moon, especially -- and you know when you look at the Moon, there's the dark areas and the light areas. The dark areas are lava flows. They're basaltic lava flows, and that's what this sand looks like, very similar to the sand that you would see in Haleakala.
Patrząc na Księżyc widać ciemne i jasne obszary. Ciemne wynikają ze spływu lawy, dokładniej lawy bazaltowej. Tamtejszy piasek bardzo przypomina piasek z wulkanu Haleakala na Maui.
