The Problem with Deep Space Exploration

      This is a summary of the very serious problems which humans begin to encounter once they attempt to travel far from Earth for prolonged periods of time.  This includes not just health problems that affect our body, but interpersonal problems that could very well sabotage the mission.  Here on Earth,  such tensions very often lead to violence as well as negligence at the job. On Earth, of course, these difficulties might be easily survivable. But on a prolonged mission in space, where job efficiency is essential, a lack of accuracy could very well prove immediately fatal.
