A new map of the moon has uncovered a trove of areas rich in precious titanium ore, with some lunar rocks harboring 10 times as much of the stuff as rocks here on Earth do.
The map, which combined observations in visible and ultraviolet wavelengths, revealed the valuable titanium deposits. These findings could shed light on some of the mysteries of the lunar interior, and could also lay the groundwork for future mining on the moon, researchers said.
"Looking up at the moon, its surface appears painted with shades of grey — at least to the human eye," Mark Robinson, of Arizona State University, said in a statement. "The maria appear reddish in some places and blue in others. Although subtle, these color 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 results of the study were presented Friday (Oct. 7) at the joint meeting of the European Planetary Science Congress and the American Astronomical Society's Division for Planetary Sciences in Nantes, France.
