      Back when NASA was flinging things into space for the first time, the tolerances that were even possible were extremely tight. Every pound mattered (every pound still matters, but because we have other things to do once we get to space nowadays, plus every pound is expensive).

      600 pounds of white paint for the fuel tank was considered unnecessary, once the engineering team figured that it didn’t actually protect the special foam covering of the fuel tank anyway. Thus the distinctive orange color!
