I do not believe that you are correct.  We have a great deal of experience
with "large" crews functioning under very trying conditions requiring
exacting performance with NO "sunlight", with different people working
at different periods around the clock.  Quit thinking "above the 
atmosphere" and think "below the atmosphere".  Ballistic Missle Submarines
perform under those conditions, and do not surface from the start of their
patrol untill months later.  And they never can "stop" or they die.
(somebody has to keep the engines and life support going!)

(I posted something like this before, but was amazed at the number of folks
that mailed "What is SSBN?"!!!)
