      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!

        Oh, I thought the pictures were backwards. The orange being the natural color and the white being paint is really critical information for it to make sense lol

        For all the people in the world except the ones from Liberia, Myanmar and the United States, 600 freedom units = ~272 kg

    Orange makes it go faster. Not the fastest color but it’s up there.

      But, why ? You drink a bit more water that day and it’s void.

        It’s a competition between brand. They’re at the point where decrease a single gram is incredible task and are all racing to become the lightest weight and aero-est bicycle and get to claim that.

    I’m too dumb for maths because I have dyscalculia, but i am always amazed by the engineering crowd on how they could improve efficiency by finding and tweaking just the little things.

    Fun fact: Columbia, pictured with the white tank, was the heaviest shuttle and was not modified to have the airlock necessary to dock with the ISS because the performance losses compared to the other shuttles made it difficult to use for ISS operations.
