One unsolved issue is cosmic rays. Astronauts traveling through space for an entire year will have their DNA pretty much trashed--fatal radiation dose. It's not much better on the Martian surface as the atmosphere is not thick enough to prevent bombardment.

Cost. Nothing more.
The cost of sending a manned mission to Mars is the ONLY reason we haven't been there yet. Humans could easily be there and establish a base on Mars in less than 5 years.
In fact, if 15% of the money wasted on the war in Iraq, had been spent on such a project, it's estimated that there would be a team on Mars already.
Speaks volumes for Bush's priorites don't you think?

Man to the Mars? Hm. The candy bar or hostile environment?

With current technology it would take two years to get there. Food becomes an issue, since storing that much food would jeapordize fuel capacity. (It weighs a lot) So, how do you keep humans fed for two years without packing two years worth of food? Find a way, or get there quicker.

Cost. The technology is probably feasible, but it is prohibitively expensive to go to Mars.

Money is a huge issue, as well as travel and fuel.

low gravity. the time it would take to get there + low gravity will completly waste a human's mucles
