You really want to know?
The american mission (if accepted) is to go very soon to the Moon, Mars and beyond because they dream to go NOW (cf. Star Trek etc...).
The european mission (if accepted) is to be ready for when they'll need to go or for when they'll need to be ready to go or for when it will be clear that one day they'll really need to be ready to go (Moon, Mars and beyond... of course)... and because american will go soon.
The Russian mission (if accepted) is to go nowhere because there is no reason to go. But, because other nations want to go or want to be ready to go then they also want to go (and because they can go easily).
The Chineese mission (if accepted) is to go soon because the other nations can go soon.
Conclusion: without the “Star Trek” fiction I wonder if the World would want to go in space... People are unaware of the true importance of captain Kirk and Spok etc... (you saw Griffin in a recent speeche? He said: "I'm like Spok"...) and remember the shuttle "Enterprise" from Star Trek etc...
Without the "Star Trek" fiction: no space exploration!!!......
