This year the Apollo 11 mission turns 50 - but what does the future hold for the Moon? The ephemeral shadows cast by human artefacts may soon be joined by more permanent scars of lunar mining.
No country can lay claim to sovereignty over a planet, moon or rocky body. But in the absence of clear laws regulating mining in space, it's a case of first in, best dressed for resource extraction.
Why carry building materials from Earth into space, when we can build structures by 3D printing using materials found out there?
Space mining could generate a massive resources boom. Here's a way to make sure the benefits of that boom reach everyone on the planet.
We're on the cusp of being able to consistently launch and land rockets, greatly reducing the cost of space travel. But how long before there's a Millennium Falcon in every garage?

Mining in space is no longer science fiction. But could it end wars over resources, as Neil deGrasse Tyson has suggested?
