The case of the crazy astronaut as got me thinking, again, about the proposed mission to Mars. Do you suppose that we can really design a space craft capable of housing x many astronauts for a multi year mission to Mars and not have a case of mass murder suicide half way there? US Submariners typically spend 3months at a time under water, not sure how many ex submariners you know, but I know several. Those that I knew before and after their time underwater, enclosed in a steel tube with somthing like a dozen dozen other men, came back different. Can you imagine spending yrs trapped in a small steel capsule ? Can you imagine spending years trapped in a small steel capsule with Lisa crazy women Howak? Previously I have been told that the selection process and milatary disipline would prevent such an occurance, can we still make that claim? Perhaps, sooner then later, we should select a crew and lock them up in a mock up of the Mars capsule just to see how long it takes for someone to go over the edge.
