    Sadly, most of this sexy hi-tech we love so much is for killing people. "Payloads into space"? I think it will find other uses too, eg: "US to deploy hyper-missiles" http://www.guardian.co.uk/usa/story/0,12271,135096 4,00.html describes mach 10 missiles capable of destroying stuff anywhere on earth in two hours. Just what we need. Yay nasa!!!

    ah, yes, the energy it would take to get them there would be greater than what is allowed a heavy payload to the ISS, and putting them in the path of orbital debris makes more orbital debris.... your not a smart guy are you.
