How about the moon, NASA and others have been looking at mars for years, they see no issues, well plenty of issues, but nothing unworkable. So I don't see it as a problem. Isn't it also massive em fields that affect humans, rather than low to zero.
Slightest chance is to much? The rocket could explode on takeoff. Pioneers, are not put off by such risks.
Well duh, but the risk of going crazy, its not a quick end at all.
Plus we are talking about years here, not small stays on a moon.
I am not sure if it is actually massive EM fields...there are a lot of studies on this but i cant really be sure here, but it probably still has an effect, if subtle. Like depression, which is already amplified by the small amount of people going, which usually isnt a problem if you see them often or are trained to deal with it, but I doubt it goes away.
Its complex i suppose.
Edit: There's also the aspect of feeling like you are permanently cut off from society because you aren't coming home, no matter what you think, so perhaps a severe home sickness as well?
