Map of Moon Reveals Titanium Treasure Troves

A map of the Moon combining observations in visible and ultraviolet wavelengths shows a treasure trove of areas rich in Titanium ores. Not only is Titanium a valuable mineral, it is key to helping scientists unravel the mysteries of the Moon’s interior.  Mark Robinson and Brett Denevi will be presenting the results from the Lunar Reconnaissance Orbiter mission today at the joint meeting of the European Planetary Science Congress and the American Astronomical Society’s Division for Planetary Sciences.

“Looking up at the Moon, its surface appears painted with shades of grey – at least to the human eye. But with the right instruments, the Moon can appear colourful,” said Robinson, of Arizona State University. “The maria appear reddish in some places and blue in others.  Although subtle, these colour variations tell us important things about the chemistry and evolution of the lunar surface.  They indicate the titanium and iron abundance, as well as the maturity of a lunar soil.”

The Lunar Reconnaissance Orbiter Camera (LROC) Wide Angle Camera (WAC) is imaging the surface in seven different wavelengths at a resolution of between 100 and 400 metres per pixel. Specific minerals reflect or absorb strongly certain parts of the electromagnetic spectrum, so the wavelengths detected by LROC WAC help scientists better understand the chemical composition of the lunar surface.
