Is Mining On The Moon"s Horizon?

A U.S. company is taking what it hopes to be a small step toward eventually mining the moon.


Las Vegas-based Moon Express just unveiled the design for a small robot spacecraft about the size of a coffee table that it says could move about the moon’s surface powered only by solar panels and hydrogen peroxide.


The company hopes to build the robot and send it to the moon by late 2015, win the $ 30 million Lunar X Prize from Google for the first privately funded moon rover, and eventually get around to putting on the moon an operation capable of extracting valuable minerals.


Even if all goes as planned, that’s a long way off, says Bob Richards, co-founder of Moon Express. It would take repeated moon missions over the next decade before any mining could begin.


“Everything we fight about on Earth, all the resources are available in infinite quantities in space,” says Richards, pointing out the moon has platinum and other rare Earth elements. “The moon is the first shopping market next door to us.”


But Moon Express isn’t the only one eyeing the potential business opportunities on the moon. China’s recently-launched lunar probe also will look for natural resources. And Pittsburgh-based Astrobotic Technology is aiming at the Google Lunar X Prize with space exploration, tourism and resource-harvesting in mind.


There are others in the game, as well. And the United Nations’ Outer Space Treaty of 1967 says anyone is free to harvest resources on the moon, a bit like the high seas.


But Tony Milligan, a teaching fellow of philosophy at the University of Aberdeen in Scotland, argued in a recent paper that the moon shouldn’t be mined unless there are much larger stakes at risk, such as survival of the human race.


“If something tremendously valuable were to be found under the pyramids or under the Sphinx we would think of it as a bad idea to go in and shift or remove or destroy these objects in order to get at it,” Milligan says. “I think we should look towards asteroids rather than churning up the moon or Mars.”

Cassini snaps two of Saturn’s moons through the rings

NASA’s Cassini spacecraft has been hanging out near Saturn since 2004, studying the planet’s icy moons. In this image taken in mid-May, Mimas and Pandora, two of Saturn’s 62 confirmed moons, hang out around 730,000 miles away from Cassini’s narrow-angle camera.


Little Pandora doesn’t have enough gravitational pull to whip itself into a spherical shape, which is why it kind of looks like a jelly bean. Scientists think its shape could be a clue as to how Saturn’s rings formed. And though it looks huge in comparison, Mimas isn’t so large itself. It’s the smallest astronomical object that’s been rounded by its own gravity.


Cassini has had its mission extended twice since it first launched in 1997. Its current mission, the Solstice Mission, is mainly focused on studying Saturn’s larger moons, Titan and Enceladus.
