I fantasized about this since I was a kid. Now it seems (http://www.nytimes.com/2014/12/09/science/a-one-way-trip-to-mars-many-would-sign-up.html) the one-way trip is seriously being considered.
So, my question is: Would you signup for a trip knowing that you have a short time, say 4 weeks, of life left once you there (assuming everything goes OK)?
Would people who agree to such a thing be psychologically balanced enough, especially on the planed to conduct any missions?
But what a few weeks it would be!
