Every little bit counts
I always thought it looked cooler with the orange tank anyway
Cooler with white, but heavier.
Cooler depends on the amount of sunlight available
Context hat
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!
For all the people in the world except the United States, 600 freedom units = ~272 kg
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
Oh my eyes glossed over the word “paint”. Thanks.
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.
Its simple rocket math. Every lb of weight must consume fuel.
Si.pky. 1 lb of weight needs 1 lb of fuel to escape orbit. But the fuel has weight also. So the effective fuel you need to lift the rocket and payload is exponential
The tyranny of the rocket equation. Generally, 1% of weight is payload, 85% is fuel.
High end bicycle equipment have weight specs in grams.
It’s always hillarious to me to see boomers on expensive bikes that aim to save every gram while they could save 20kg on themselves.
Or skinny dudes with enormous ballsacks wearing tight Spandex on 15 pound carbon fiber bikes, but a 20 pound motorcycle lock.
If you are trying to lose weight, you should be using the worst, heaviest bike possible.
Perhaps that’s why they are on a bike?
Well, it’s also fun to go places you know. If a shitty bike can only get you 20mi / 30km but a on a good one you feel confident doing a 30mi / 45km ride then the purchase makes sense.
But, why ? You drink a bit more water that day and it’s void.
But what if you drank more water and you didn’t have the weight savings?
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.
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.
The real question is why the default color is orange and not white or gray.
The polyurethane spray foam insulation is orange.

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

Is NASA run by orcs

No no, that’s Roscosmos
