The moon is a rich mistress

Why are we not yet going back to the moon?
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."


Furthermore, Apollo data indicated that titanium-rich minerals are more efficient at retaining solar wind particles, such as helium and hydrogen. These gases would likely be vital resources in the construction of lunar colonies and for exploration of the moon, the researchers said.

We need to be up there mining that stuff someday. Hopefully sooner rather than later.
