Even if we had found the means to travel to Mars, there are other things to consider. How do we avoid hitting those 'infinite' asteroids? ok even if we manage to steer the ship away from them using some maths formulas and working them out in detail... how are we going to make up for gravity in space? As you all know, without gravity, human bones deteriorate rapidly. The known time for humans to exist in space is about 1++ years and that too has a heavy effect on the person's health and bones.. I don't think we have advanced so much as to find out how to create a sort of artificial gravity in space. It takes 3 yrs to travel to Mars and 3 yrs again to come back to Earth.. thats 6 yrs in all.. so imagine if you send astronauts on a mission 2 Mars.. when they come back, (they'll probably be dead), they would have grown 'shorter' from all that bone loss. I hope im correct in my speculations..
