First, I am a Libertarian. It is was you neo-cons that applied it yourselves. Basically, the reagan and W type of politicians that we can no longer afford. And you neo-cons/teabaggers are the ones that killed the fiscal conservatives.
This is delusional. First off, the Libertarian party is run by truthers and John Birch-style cranks. It has no coherent platform beyond "cut my taxes and your services". It will never, ever be a serious party in the US without a wholesale change in both charter and leadership. The Tea Party people are the ones who are the actual fiscal conservatives these days, and the fact that you label them "teabaggers" and lump them in with neocons displays a shocking ignorance. You call yourself a Libertarian but your political outlook is bog-standard dorm room Marxist.
Because the more that you launch the lower the fixed costs. That was the idea of the shuttle that Nixon pushed. Sadly reagan killed that.
Because it's not true in practice. Launching the Shuttle a bunch of times only makes each flight marginally cheaper because it was designed for performance instead of operations - there's simply too much that has to be done between flights. So great, instead of paying a billion a flight you have the cost down to $500m (and here I'm being generous), but to do it you need to quadruple the NASA budget so you can fly every couple days. Not that you could do that anyway with only four shuttles.
Doesn't make sense. We will never, ever have practical access to space with the shuttle, no matter how aggressive the launch schedule is. And what are you going to do with all those flights to LEO now that you have no money for anything but launching?
Later the neo-con congress of 2000 forced NASA to not develop VASIMR or transhab. Thankfully, a patriot pushed transhab into BA, while an astronaut/engineer/physicist with the help of NASA created a new rocket engine.
There was never a neocon congress. Is that your definition - "a neocon is someone who does something I don't like"? No wonder your world is full of them.
VASIMR isn't the holy grail of rocketry, it's just a new twist on ion engines. It will never be powerful enough to be used as a primary stage booster. In other words, it does nothing to get us out of the blind alley we went down forty years ago. I have a lot of respect for Chang-Diaz for not giving up, but even if everything works out the way he wants it won't have much effect on the overall picture.
