Wow. Just wow.

Took me a sec.

What is the plausibility of painting the first moon-landing BFR like the Tintin rocket? (or at least a booster)

What is the plausibility of painting the first moon-landing BFR like the Tintin rocket? (or at least a booster)

paints adds a fair bit of weight surprisingly

Thanksfully weight doesn't scare the BFR.

As others have said, paint provides a heat management function.

However, I wouldn't say it's completely impossible, because BFR will be designed to hold fuel over the entire length of a trip to Mars. Its heat management will be robust enough to keep its fuel cryogenic over several months, and a trip to the moon takes about a week. Adding red paint gives it extra heating from sunlight to deal with, but since it will need good insulation and large radiators anyway, that might not matter much.

The underside of it cannot be painted, because it has to be heat shielded, and paint would burn off. You don't want that kind of complication on a critical safety element.

A bigger problem is that spaceship paint isn't cheap or easy. You can't just take some spraypaint and add a sealing layer over the top.

One of the major upgrades happening for the Block 5 F9 booster is a new, more durable type of paint that won't need as much cleaning, inspection, or replacement, and it took a long time for SpaceX to reach that step.

You are still thinking with the "every kg count" paradigm

That's because it literally does count against the payload delivered into orbit. SpaceX doesn't have a "just throw this on there cause who cares" attitude. They consider the total cost - buying a bolt for 3x the cost to save a few grams isn't worth it, but titanium grid fins (very expensive) are worth it vs aluminium for their lower weight and better heat resistance.

If boil off was a non issue on a LH2/LOX tank

(boiled off propellant can be topped up, making it a non-issue)

it will be too on a LCH4/LOX tank

non-sequitur. What if they use subcooled methane? that doesnt boil off, it just warms up and expands, and can't be re-chilled in the tank.

that is designed to be insulated for months in outer space.

The first stage? it isn't.

Not that hard. They're fairly 肛門.

Is this a new photo of luck?

Anyone recall the name of the vine this is from?

Nice. He does look great! Makes me feel a little better about the shoulder

Looks so mean

T_D commenter peddles the "White Genocide" conspiracy theory, regarding South Africa

T_D commenter peddles the "White Genocide" conspiracy theory, regarding South Africa

This thread is so full of stupid racist shit. Fucking nazi pieces of shit.

Dumb fucks like Stephen Colbert think it will be a good thing if white people are no longer the majority because it will mean unopposed Democrat rule forever.

"I'm not racist, but I'm afraid of brown people because they might one day treat me how I treat them!"

From the Wiki on white genocide, regarding South Africa

However, Africa Check, a fact-checking organisation has rejected the claims as false: "In fact, whites are less likely to be murdered than any other race group." Africa Check reported that while whites account for nearly 9% of the South African population they represent just 1.8% of murder victims.

Oh look a human centipede

Fuck all y'all

I have Tourette’s. Fuck you.

With love.

But fuck you.

Give me pixels you little fucker

FUCK YOU! That was awesome, I'm still giggling!

And fuck you n'all
