Ilmenite Seen with Ultraviolet Light

01 Dec 2017

WAC mosaic lunar nearside — The low-reflectance portions of the Moon are composed of mare basalts, which formed via large eruptions of lava in the ancient lunar past. Variations in reflectance within the mare depend on composition, in particular, the abundance of the iron- and titanium-rich mineral ilmenite and glassy material erupted in huge explosive eruptions. The darkest materials are either ilmenite rich basalts or explosively erupted ash, and the multispectral capability of the Wide Angle Camera (WAC) allows scientists to discriminate between the two materials.
