"On a related point, I still get upset when I see them having to rearrange the pieces of the ISS every other month or so. Didn't these guys ever build a tinker toy? and so on. "<br /><br />Oh now come on! Lets see we moved PMA2 on 5A (2001), P6 on 10A, Node2+PMA2 during the stage. How the heck is that moving something every month or so? Pay attnetion to what is going on before making such statements. It was pictured from one end to the other and there are some ways to not have to do some of this stuff - like for example having TWO station arms. But the cost, even if we could afford it, would not have justified the minimal benefit. I don't think reusing a module is practical at all - they are fairly specialized, would be nearing the end of their design life and can't just be unattached and moved somewhere else. You would spend more money/time then just making a new one.
