NASA sets out to buy moon resources mined by private companies

NASA on Thursday launched an effort to pay companies to mine resources on the moon, announcing it would buy from them rocks, dirt and other lunar materials as the U.S. space agency seeks to spur private extraction of coveted off-world resources for its use. NASA Administrator Jim Bridenstine wrote in a blog post accompanying the announcement that the plans would not violate a 1967 treaty that holds that celestial bodies and space are exempt from national claims of ownership. The initiative, targeting companies that plan to send robots to mine lunar resources, is part of NASA's goal of setting what Bridenstine called "norms of behavior" in space and allowing private mining on the moon in ways that could help sustain future astronaut missions.
