It may not prevent travel to Mars (for example, on a centrifugal space station), but considering gravity on Mars is 62% lower than here on Earth, I would postulate without some kind of gravity manipulation we are yet to develop (unless we have the energy to build centrifugal colonies on land) then manned missions on Mars would suffer a similar fate.

Until relativity and the standard model can be merged and we can figure out a cause and effect between gravity and other fundamental forces and figure out who to trigger gravity with an electrical switch for example gravity manipulation is not going to happen for quite some time. We'll probably just take the risk and go to Mars and suffer the health consequences.

Or find a way to treat the problems directly, rather than avoid them using artificial gravity.
