"All space projects get into orbit pretty much the same way â€“ by burning lots of rocket fuel, a spaceship powers itself past the sky. But what if there was a different approach? What if we could throw something so hard, it would wind up in space? At NASA's behest, Ed Schmidt and Mark Bundy of the Army Research Lab are looking at ways of firing projectiles into orbit." - Defense Tech

I will be curious to see how much success these space-shooting missions will generate in comparison to the traditional space rocket launch. I can say with confidence that no levels of success will ever be enough to convince me to be willing to risk my life by stepping into this giant slingshot.
