Do you guys know the Mars Direct Program? It was developed by Rober Zubrin. The point of the program is that we are technically able to go to Mars. We were it 15 years ago en today we still are. We can do it relatively cheap (20 billion) and without need of in-orbit build spaceships.
I recommend reading The Case for Mars by Rober Zubrin.
