Realistically, the chinese are the only country with the economy and the will to make the next stepping stone in space exploration and travel.

Governmental pushing of a envelope like space is needed before private enterprise can piggyback on that.
Commercial space exploration will also play a roll, but is totally dependant on money from peopel that are willing to spend without any real immediate economic benefit.
Any other ideas , Comments ?
