Five years ago, if you had brought up moon mining among geologists, “you would have been laughed out of the room,” said Gordon Osinski, founder and director of the Canadian Lunar Research Network, and an assistant professor of geology at the University of Western Ontario.
Times have changed. Mining on the moon and on asteroids, formerly the stuff of science fiction, is clearly in the sights of governments and, increasingly, private companies.
In February, NASA announced it was accepting applications from U.S. companies to build robots for lunar prospecting, a step toward creating an economy in space.
And there’s certainly a market for what’s up there. Many elements that are rare on Earth can be found aplenty on the moon. Satellite imaging has shown that the top 10 centimetres of regolith (moon soil) at the south pole of the moon appears to hold about 100 times the concentration of gold of the richest mines in the world, according to a recent paper coauthored by Dale Boucher, the CEO of Deltion Innovations, based in Sudbury, Ont.
