The landing of the Space Shuttle Endeavor, with its six astronauts, at the Kennedy Space Center in Florida, late Sunday night, marked the end of  twelve years construction, costing one hundred billion dollars, for the sixteen nations owned, International Space Station. The Endeavor  carried the station’s final connecting  hub,  a new life support module, which includes a toilet, a water-recycling system,  an oxygen generator,  an air scrubber and an exercise equipment, and of course,  to make the station a comfortable and inviting place for Star Trek fans  -- an observation deck with seven windows, so  that astronauts -- or  future space tourists can gawk at the view?
