Lava flows that turned into rocks on the moon are enriched with titanium in concentrations far higher than what is found on Earth. The precious material could be used to construct equipment for lunar and other spacecraft.< Detailed maps from a robotic NASA science satellite circling the moon show deposits as rich as about 18 percent, planetary geologist Jeffrey Gillis-Davis, with the University of Hawaii, told Discovery News. “Up to 3 percent is considered high on Earth,” he said....
