I really think that rocket technology, however it is powered, is not what we need.

Currently we are thinking in terms of shooting something out of the rear of the vehicle and propelling it in the other direction, but I think we need to consider other means of propulsion.

Unfortunately, while military solutions to this problem are still classified, the result is, we are stuck with the need to build larger and larger rockets, planes, etc to lift heavier loads. So, although I think that any money spent on space travel is still useful to the economy, what we really need in order to get to the stars, is for the military solutions already developed to be released out to the public for our use.

How do you know they havent created this yet?

Keep in mind, there is a WHOLE LOT when it comes to aircraft technology, that the public is not aware of. this is one reason i think its almost pointless to even discuss this kind of technology, as there are large parts of the puzzle that are withheld from us, so its nearly impossible to even speculate about.

I think our collection of overgrown children need to learn a thing or two about hard science; it's called that for a reason.

NASA gets 0.5% of the budget. I'm sure there are fractions of a % that can be pulled from here and there.

I think NASA is essentially the official Public Relations part of the US space industry and it releases the information we are supposed to know about and believe. Much of the actual space engineering and construction appears to be done by other companies which do not have to answer to FOIA requests and which probably get their funding through a different channel. In considering this, we have to remember there was a large black budget anomaly reported in the finances a few years ago and I doubt if that particular Black Hole has disappeared in the time since then.

Also I think there are many aspects of new space technology which are developed by the military and this technology is completely separate from what the public are told by NASA. This means that even though NASA's budget may be relatively small, space technology can still be developed and produced.

Yep, none of us know how much money the Black budget gets, but we do know there is a 'black budget' every single year.

We'd still have to get the fuel there. Sure, it's LEU, but it's still not something you want dispersed...

Nuclear fuel, near Earth? Well, you build the ship out well away from Earth - preferably in lunar orbit, just to make sure. & you mine & purify the uranium or plutonium or exotic hydrogen or whatever you're using for fuel - either on the moon, or in orbit in the asteroid belt.

The point is to minimize environmental impact to Earth - even if you have to launch the main ship with skeleton crew & only partially finished - enough to run the main engines & get it away from the Earth/moon system. Or you could even strap on non-nuclear boosters just to get it away from the moon, & light off the main engines when the ship is well away from civilization.

There are lots of ways to skin that particular cat.

Frankly, if we have lifting capacity to put a practical mining operation on the Moon or in the asteroid belt, we also have a resolution to the problem we set out to solve.

Problem with mining and purifying rare elements like uranium (you can't mine plutonium) is that they're just that - rare. On Earth, with our active geology, ores with higher concentrations will form. In the asteroid belt? Much less likely, unless our understanding of asteroid geology (asterology?) is deeply flawed.
