There’s gold in them hills! Actually, it’s titanium, and it’s on the Moon.
The highest titanium abundances on Earth are around 1 percent or less. The new map shows that in the [Moon’s] mare, titanium abundances range from about one percent to a little more than ten percent. In the highlands, everywhere TiO2 is less than one percent. The new titanium values match those measured in the ground samples to about one percent.
