This might be a show-stopper perhaps?

Mini article

Quote:
The study looked at periodic ultrasound tests of 11 healthy astronauts who staffed the International Space Station.

The results were alarming: blood flow had either stagnated or reversed in the left internal jugular vein, a major blood vessel on the side of the neck, in seven crew members. The tests also found a clot and a partial clot in two of the crew members after their return to Earth.

Not sure it's a show-stopper, I think it's been well known for awhile that long term zero gravity and radiation in outer space isn't going to be good for the human body. Heck, even with the all the redundant safeties built in, the space cowboys and cowgirls can still be killed on launch.

I feel most agree a trip to Mars with people is probably a "suicide mission" and even then, I think NASA or any of the other space agencies around the world could easily find hundreds, if not thousands of volunteers who would be willing to go!

Yes that's a concern. We should really set up a long duration centrifuge in space to test the effect of Mars gravity on rat bodies over several years.

If I didn't have a family I'd sign up for Mars for sure.

That part is true, the Mars One project had already attracted tons of applications.

I think it's fair to say those applicants weren't realizing potential life-threatening health risks just to get there. In addition, I think about 50% of the missions to Mars have been failures of misses and crashes.
