The Mineralogy of the Moon from Remote Sensing Data
Quick fact
Remote sensing instruments on lunar orbiters, like the Moon Mineralogy Mapper (M3), have identified that the lunar highlands are rich in plagioclase feldspar, while the maria are dominated by pyroxenes—a distinction that supports the theory of a lunar magma ocean.
Why this is interesting
Did you know that scientists can tell what minerals are on the Moon just by measuring the colors of sunlight reflected off its surface, without ever landing?
