"When you go up there for construction, not only do you have to bring the material to do the construction and all the equipment to do the outfitting, but you have to bring every single little tool that you might require, every infrastructure that you require to build the actual station. And then you have to bring every single thing you need to sustain the lives of the construction workers, the crew members, that go up there, because there is absolutely nothing. As I often say to people, unfortunately, there is no hardware store around the corner, so if you forgot a particular type of washer or you don't have the right screwdriver, well, you can't go back and get it."
