The Human Body Isn't Ready For Mars
At least not yet...
We're very close to having the technology to send astronauts to the Red Planet, but that doesn't mean the human body is physically ready for such an endeavor. Right now, it would take between six and eight months to get to Mars and during the trip astronauts would be at risk for vision impairment, bone density loss and even muscle atrophy.
NASA is currently running tests to try and prevent these issues from occurring, but it could be a while before we're fully confident that our astronauts will be safe on the journey to Mars.
