As we’ve written here before, future wars could well be fought in space. The US Air Force is now looking for ways to protect crucial American interests in space.
The USAF is working on a project to build a so-called space fence that will be detect threats and protect American satellites from debris and other space faring powers that might want to harm them.
The fence in this case is no fence at all, but an advanced radar system that will be able to track objects in space the size of a baseball ball.
