The biggest obstacle that needs to be resolved for any potention mission.

1. A demonstrated technology that solves the radiation exposure problem. Right now the estimated risk is just too high i.e. a trip to the Mars would kill potential astronaut prematurely. One of the Apollo missions missed a deadly solar storm by only few days. NASA will not go the route of waiver agreements.
Radiation exposure is the modern day sea monsters. A lot of nonsense. Sure there's radiation in space but its a minor engineering and/or medical issue. Besides, space travel is dangerous; that's just the way it is and always will be. An astronaut could just as easily die in a car wreck.

The biggest obstacle that needs to be resolved for any potention mission is fear.
Well now you are just talking out of your arse. Fear is not an issue since there are about thousands of qualified people willing to volunteer for an one-way trip but as I said before we are not going to go that route. If we are going to do this we are going to do it properly and with the minimization of risk. Otherwise you get something that blows up completely in your face. The radiation issue isn't comparable to some modern day sea monster. It's real and it's not a minor engineering issue. Most people who are heavily involved in the manned mission area here at NASA Langley agree that it's at least one of the biggest obstacles. Of course all the other details that are currently being discussed by others in this thread like In-Situ utilization are also challenging engineering problems but I rate them as something that is more tractable.
