No one has yet walked on mars, it would take about 60 years to get to mars in a space ship, that's because our cerebral fluid (Spelling mistake might be) helps us balance etc, and it will be damaged if we went 7 months, as fast as a probe goes. As you can see humans only support really the slowest speeds.
^ Whoever wrote this is an idiot. While no one has yet walked on Mars, NASA intends to send a human crew to the red planet sometime in the next 20-30 years. The voyage lasts approx. six months, and the main concerns are radiation shielding for the trip and while on Mars, and sufficient rations for the three year round-trip. Mars' orbit is longer than Earth's so astronauts will have to stay on Mars for two years after landing, in order to take advantage of a launch window giving them the shortest distance to return.
