I always thought it looked cooler with the orange tank anyway
Cooler with white, but heavier.
Cooler depends on the amount of sunlight available
Removed by mod
I thought Cell was green?
No that’s when Cooler fuses with Picollo to become even cooler.
Pooler? Coocollo? Picoler?
Coolio.
Cooler with orange, and lighter.
Orange makes it go faster. Not the fastest color but it’s up there.
Is NASA run by orcs
No no, that’s Roscosmos
We put a lot of meaning on ‘Boots on the ground.’

Although tbf all those achievement were by the Soviet space program, where Roscosmos has been… well, less successful especially recently thanks to all the money going to murdering Ukrainians
US just put enough into the
CHAstat to decide which achievement is worth bragging about.
Oh boy. That was funny.
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 ones from Liberia, Myanmar and the United States, 600 freedom units = ~272 kg
Thank you, finally something sensible
That’s 4 and half men. Or a minivan’s worth of kids. Or 100 buckets of KFC
So about 31 adult badgers.
also Canada. because we don’t use metric in contexts like this
You can just give a conversion without being snarky about it
And you could just use standardized metrics that is used by the entire world. Like many Americans claim they can. Yet here we are.
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
Yeah same. Orange is much more iconic, glad this happened.
Oh my eyes glossed over the word “paint”. Thanks.
High end bicycle equipment has 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.
Perhaps that’s why they are on a bike?
If the point is to burn calories, then shaving weight off your equipment is counterproductive.
But if it makes you want to ride more, then great!
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.
Well, not if you still want to have some fun while doing so.
But I agree, that a regular bike should suffice and you don’t need to worry about optimizing gear weight if you’re not competing for anything and just ride it for your own well-being.
Well, not necessarily. A bike that’s got a full carbon frame also absorbs shock and vibration from the road better. This means you can ride longer distances without getting fatigued in places like your wrists or ass. Longer rides = more exercise.
But once you have a carbon frame, chasing grams on other components gets to be a bit silly.
I’ve yet to ride a carbon frame for any amount of real distance, so idk how good they actually are.
But having a less harsh ride can also be archived by not using the thinnest pizza cutter tires at 10 bar. Especially if we care about time ridden and not avg. speed.
And it’s going to be slightly harder to get the same speed out of comfy tires, so that’s also more exercise.
You could also just walk whenever possible, burns more kcals/distance
That’s less efficient time-wise though, since it takes significantly longer to walk the same distance compared to riding.
Ie, riding 2 hours burns FAR more calories than walking for 2 hours.
I enjoy walking and don’t mind walking even for 40 minutes in the morning. Not every day, but if it fits in the schedule it gives me more movement in practice than a bike (also due to some local circumstances).
The point was more generally that walking is a great alternative. Everyone hypes bicycles, walking has no lobby and is one of the healthiest things to add to your day.
Also, if the goal is to lose weight, cardio is fine but only supportive at best. It’s way more effective to eat less calorie dense food than trying to run/bike it off. The difference between an hour walking and biking is negligible for most people compared to dietary changes.
The difference between an hour walking and biking is easily 10+ miles, not exactly negligible if you have somewhere to go.
So using fewer calories.
That’s a stationary 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.
And then you have E bike companies producing lead bricks that are non-functional without the motor doing 90% of the work. Or with the massive motorcycle seats that make pedaling actually impossible.

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 harder stuff is orbital mechanics. Getting things into orbit is easy. Having thwm go where you want is the hard part.
The tyranny of the rocket equation. Generally, 1% of weight is payload, 85% is fuel.

The sooner humans can move past rocket tech the better to be honest.
Stop living in a gravity well and we wouldn’t have to expend energy to get out of it!!
- Artemis tanks were 10m wide and 30m tall.
- Cylinder surface Area = (2.pi.r2) * (2.pi.r.h) [1]
- 2 * pi * 5 * 30 ~ 1100m2 to paint
- Paint paints about 10m2 per Litre paint
- Need 1100 / 10 = 110 Litres of paint
- 1L of paint weighs about 2kg
- 110 Litres of paint weighs about 220kg

Til dyscalculia. I hope you weren’t born in asia
I am Asian 😂 I refuse to live up to the stereotype!
Or expectations!
Or are you a doctor?
I won’t go too specific but my background is in biotech.
So… you’re going to be a lawyer then?
I already work on STEM, without the E, but a little bit of M.
How are you doing m without being m?
It’s regulatory requirement to use calculators in my field to make calculations, so that has been saving me.
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.
But didn’t it have ejection seats at one point?
IIRC the original Shuttle design called for an ejection mechanism around the entire cockpit. During STS-1 and I believe STS-2, which was also Colombia, there were extra emergency mechanisms present, but I don’t think the seats themselves ejected through the roof like a fighter pilot’s would. For the most part though these were useless as they could not be used above 30,000 feet or something like that so it could only be used during the first minute or two of the flight.
Several of the safety mechanisms and other things that were going to be part of the original design that had not already been scrapped for weight (like jet engines for powered decent) were scrapped for weight when the DOD stepped in and offered NASA extra money for the Shuttle if the Shuttle could hit very specific, higher and less fuel efficient, orbits. This came from an offhand comment that Jimmy Carter made, and then had to make good on the threats and implications of.
The real question is why the default color is orange and not white or gray.
The polyurethane spray foam insulation is orange.
That’s the default skin. It costs 100,000 doubloons to unlock the sick neon green and black skin.
That’s only if they release the DLC. Devs keep blowing their budget on the tech tree

SIX HUNDRED EL BEES? HOLY FUCK THAT’S A LOTTA PAINT.
Remove all the tanks and shit on the bottom to really save weight and just let the shuttle fly? It’s not rocket science.
Found the Kerbal Space Program player?
Though isn’t that decreasing the aerodynamics and increasing the friction?
Probably, but the slowest part of the trip is in the most dense air. Probably still a net benefit!
No the purpose of the white pant was to help keep the external tank cool to reduce fuel boil off. The foam insulation was incredibly rough, not something a thin layer of paint could smooth over.
