refurbishment to go to the pad again. >> will the same type of strategy be used to shuttle our astronauts rather than hitching rides with the russians? >> well, i tell a lot of people when i teach and speak that i wouldn't bet against elon musk. from what i've seen him do, he will hopefully do what he says he can do and that would be to give america the capability to launch astronauts from american soil again. i'm all for that if he can do it. >> clayton anderson, thank you very much. two things to watch here, the link-up of this spacecraft to the international space station to drop off all the goodies and then the separation with the booster rocket that will essentially -- that falcon 9 rocket hopefully be reused again and again and again. it's got to land on that barge without crashing on that barge and be constantly repurposed without starting from scratch. the space shuttle was the impetus for this type of technology. but this would be something on a far grander scale going forward,
