Originally posted by: WhiteKnight77 Cost is the biggest reason why. While at the time of the original moon landings, we wanted to show the Russians that we could send someone to the moon, the hidden message was, we could hit you with an ICBM. To build a rocket powerful enough to send a man to the moon now would run in the billions of dollars and people in Congress would object on the grounds that their constituents would object. Look how long it will build the ISS and how much that will cost even split amonst several countries.
