Getting materials and people into orbit has always been an expensive proposition, one that's even costlier now that the Shuttle program has been retired. But one enterprising American inventor thinks he's got a solution: Space Cannons.
Watch the International Space Station's cannon in action. It's name is J-SSOD and it's attached to the Japanese module Kibo. But wait, you say, what happened to the no weapons in space thing? Is this Death Star Alpha?
If John Hunter—a former physicist at Lawrence Livermore National Laboratory—is successful, the International Space Station may start receiving their supplies from a cannon. No, it's no joke.
