Sometime after the 9m starship is made, I assume. It'll also be more squat, so it'll actually look like a bullet. Like, the actual projectile.

Current expected specs is ~100t with hopes that they'll get it to 150t with time. I don't know where you got 300t from.

Why were the Soviets unable to into cylindrical tanks? Is it a metallurgy issue or were spherical tanks just easier/better for some reason?

It boggles my mind that the Russians were able to manufacture basically the most advanced rocket engine of all time (that we still use today), but couldn't make cylindrical tanks.

>>11814965
Fuck off with that shit. Take it to /tv/ or wherever it belongs.

>>11814965
Having threesomes with models sounds pretty based.

>>11814966
A spherical tank is the strongest and therefore the easiest to build, but isn’t space-efficient. If you fill a box with a bunch of balls, there’ll be a ton of empty space in between the balls.

>>11814967
No.

>>11814972
So basically it was a strength/ease of manufacture issue?

I guess that makes sense. Anyways to real problem with the N1 was not testing the fucking engines before launch and that was more a product of Soviet shoestring budgets more than anything.

>>11814975
>So basically it was a strength/ease of manufacture issue?

Yes, but I have no idea why they couldn’t just figure out how to make cylindrical tanks. Big spherical tanks only make sense in practice if it’s holding LH2 as part of a long-range NTR

>>11814930
So a rail gun can work if we have a 63 mile long ramp. And that's to fire a space shuttle with people. There are rail lines and oil pipelines and power lines that do that easy.

And what's to say we have to fire mass? Pop out a particle on Mars, pop it back with spontaneous generation. You have all the data that's there for high accurate measurements here on Earth. If you need mass, there are molecules and fullerenes. Space launch like we emit a data signal. Focus energy from the Sun, and use that as your manufacturing process. Crash silicon air and nanowire batteries to Earth.

>>11814975
The engines were produced on the other side of the union and were shipped in several shipments over time to where the rocket was being built. The same with the plumbing.
So the entire was never fucking tested until it was fully built and ready to launch.

The engines were working, the tanks were working too, the plumbing shook itself apart under strain of all those engines, but they never fucking tested all engines firing at the same time, so they never fucking knew.

>>11814965
I'm curious, why you care so much about personal lives of people? I see that type of interest from low IQs usually. Am I to assume sub 80 IQ from you?

>>11814982
Probably just some kind of Soviet autism. I'm sure they could build large cylindrical tanks but some high level designer forced spherical tanks because of "muh rugged Soviet reliability."

Soviets always seemed to value strength/reliability of design rather than pure function.

>>11814984
I never heard that about the plumbing, I may have to look more into it. I've always read/heard that it was the engines themselves that kept failing because they never test fired them. It's hard to find good English sources on the N1 design though so i'm not surprised.

>>11815002
The engines were test fired, but the complete first stage was never test fired together.

>>11814943
That's what made N1 "only" capable of putting 95 tons into LEO, though. If N1 had the structural efficiency of, say, Falcon 9, it would have been capable of much more. Probably would have been simpler to build and more successful in testing, too.

>>11815026
I'm not sure about the specifics, but the entire stage setup was *never* test fired before it's maiden flight. That much I know, the plumbing shaking itself apart and rupturing in a ball of fucking fire is well known.

>>11815033
I recall that this was intentional since the Soviets didn't have a test stand large enough for the N1 first stage, and that they were expecting the next flight to go well before it got canned.

>>11815015
When Musk is going something relevant to spaceflight, he's relevant. Just because that's relatively often doesn't mean that I care where his dick goes or navelgazing theories about how something SpaceX is doing is because Musk was bullied in school or something.

>>11814964
You're almost not wrong, Starship is actually a ~300 ton-to-LEO class rocket, it's just base-lined at its reusable performance of 100 to 150 tons.
Likewise, 18 meter Starship would be able to do between 400 and 600 tons reusable, and up to 1200 tons expendable.

>>11814965
>Is musk a bond tier villain now?
Why would that make him a villain

>>11815037
Musk is a gigachad messiah.

>>11814982
It was never a problem of them not being able to figure out cylindrical tanks; the head engineer was convinced that the lightest option was to have giant spheres of propellant joined with a hyperboloid skeleton structure. Unfortunately he was incorrect, and N1 ended up being heavier than if they had just used ye olde cylinder with stringers.

>>11815046
Spheres are the most surface-area efficient pressure vessels and also the strongest, so that probably seemed like a line of reasoning worth investigating.

>>11815038
So you could put the equivalent of 3 ISS in one launch with a 18m starship. Nice.

>>11815002
Only one of the N1 launch failures was directly caused by an engine failure IIRC.

One blew up because of pogo oscillations, one blew up because of a fire starting in the engine bay, one blew up because an engine ingested a bolt or other significant chunk of debris, and one blew up during the final few moments of stage 1 firing when scheduled engine shutdowns caused a fluid hammer that burst propellant lines.

>>11815038
I doubt they ever will but I kinda want to see one expendable SS launch just for the books. The sheer cuckening.

>>11815038
>SS could have built the ISS in ~4-5 launches
>18m SS could have just launched the whole fucking thing in one go

Can't wait to buy my own personal space station for a few million bucks.

>>11815083
Standardized and modular space station segments seem like a viable market in the future

>>11815036
They did manage to get all the way to 1st stage shutdown on the final test flight before something went wrong, which would have been fixed simply by altering the engine shutdown sequence. The subsequent stages were tested beforehand so I think it's actually likely that a 5th flight of N1 would have succeeded.

>>11815088
Tbh if I had capital to invest that's probably where I would go. Once SS becomes cheap and routine enough every fucking University and F500 Company in the Western world is going to want their own Space Station and whoever is making prefab modules that can be outfitted cheaply for whatever use is gonna make bank. It wouldn't be an immediate return on investment but it would be worth it down the road.

>>11815051
Spheres are only strongest if you only consider tension forces from internal pressure; they suck for transferring thrust forces through, which is why N1 needed the support of the hyperboloid skeleton.
The actual 'ideal' shape of a rocket tank is a low fineness ratio cylinder with hemispherical-ish bulkheads, to approximate the surface area to volume ratio of a sphere while remaining strong enough to take compressive loads and also not add unnecessary mass (the bulkhead between two propellants for example could technically be a flat plane, as long as there remained zero pressure differential between either tank, but that's hard to manage and a flat plate makes for a shitty sump).

>>11815083
>9m Starship alone makes for a more voluminous space station than the entire ISS
>even if you launched modules, Starship can carry much larger modules at a time and for the same launch mass could therefore build a much larger station than ISS

>>11815214
they wouldn't of been first

>>11815210
I wonder by how much. Sure, the US had extensive industry for more space flight beyond Apollo, but public interest was dropping pretty quick after Apollo 11. Had the space race continued "whitey on the moon" would've hit nuclear levels of anger.

>>11815204
Retard. We've could've had a race to Mars if the Soviets landed on the moon. Imagine Mars missions in the 1980s, Saturn V never canceled but upgraded, NERVA and all other shit that might have happened instead of the memeshuttle.

>>11815217
why did the public interest drop? do people really not care about space colonization/spaceflight?

>>11815182
Yes it would, but at the time the engineers thought that they could do better by using spherical tanks to hold propellant and a hyperboloid thrust transfer structure. Unfortunately for them it didn't actually result in a lighter vehicle.

>>11815222
No they care about welfare unironically

>>11815222
Yes, most people don't. Luckily there are enough that do that we're making it happen anyway, and you can bet your ass that all of their space-born descendants will also care about spaceflight and colonization.

>>11815233
>>11815228
>>11815232
why do they not care

>>11815222
The average person today doesn't care much about space flight. Not sure why, but my guess is that its seen as a very niche interest on par of sci-fi but even less appealing. I know that during Apollo many people thought that the program was just the US government showing off and thus was a pointless waste compared to more pressing matters such as racism or Vietnam.

>>11815235

when you lift things to LEO, you are concerned about thrust-weight ratio, not volume-thrust ratio
spherical tanks are lighter than cylindrical, because forces are uniform and you can get away with thinner walled tank

Instead of having a wider first stage, it’s better aerodynamically to have a taller one.

This. American’s biggest critics are Americans themselves. You may not agree with MAGAfags but at least they’re not Doomers 100% of the time and are proud of their country.

One thing a lot of people don’t consider is that if/when other countries get to Mars, how autonomous will the new settlements be? If there’s an American mars colony at the Valles Marineris and a Russian one at the South Pole, will they be closely monitored by their home country?

Movies and games which have “Mars rebelling against Earth” all have Mars existing as one big super-country. They never talk about individual regions on Mars. Will mars be a confederacy of independent states who sometimes agree on issues?

>>11815388

A major obstacle to that is removing all the debris and abandoned satellites from above LEO, opening up HEO to large space stations that would be severely affected by aerodynamic drag at LEO.

If Boeing were smart they'd develop a "garbage truck" variant of the X-37 both for bringing derelict satellites back to Earth for scrapping and debris trawling missions where it deploys some kind of massive net from its payload bay that collects small fragments.

Eventually, the only debris in orbit would be tiny ice particles from rocket exhaust which gradually sublimate in sunlight.

Stuff set in the solar system is often pretty realistic, but can be super boring and unappealing to normies (Lots of “Hard SciFi books” and movies).

I can only think of a few middle ground instances where something takes place in interplanetary space, AND is appealing to people.

>The Expanse
>Kerbal Space Program
>The Martian

Why do people never make shit about the interplanetary domain? Is it because it’s hard and actually requires researching the settting? I can see it being easier to say:

>”Oh yeah they turned on the warp drive and battles on the surface of an Earthlike planet”

compared to

>They fought on the surface of a cold icy moon without an atmosphere again.

Thoughts?

>Mars Aeternum

Yes, and?

They're not enthusiast anything. They're failed English and sociology majors who hate the fact the only job they could score was blogging about video games that they hate and decide to throw in intersectionality and communism

What would be better for interplanetary travel, a Nuclear powered ion drive or NTR?

the best interplanetary drive we could probably get working in under two decades is nuclear salt water reactor, too bad it'd have so much red tape around it. maybe we can discover a source of large amounts of uranium on mars and develop NSWR there independently from earth

>>11815620
If we combine our hatred it would be excellent.

>>11815555
A big part of colonization is going to be changing how settlements are managed. the ISS for example is monitored 24/7 in an intensive mission control style framework. early settlements probably will be similar, but this is not sustainable for long term development

https://twitter.com/elonmusk/status/1274025664492892160 VERY UNBASED

>>11815610
lame. realistic space warfare would barely involve humans. think intensive orbital reconnaissance warfare with kinetic or laser weapons (which would be like remotely operated tugs) to take down enemy satellites and warships. surface settlements could be dealt with by nuclear bombardment or just resource blockades to choke them out

>>11815663
i wonder if elon is gonna push transgender globohomo bs on mars...

>>11815663
And of course he folds like a limp noodle because she's the mother of his newborn son and in irrational postpartum mode.

>>11815667
Not necessarily. CoaDE does a good job of explaining why that might not be the case. Light lag has a lot to do with it. Even small amounts of light lag can cause big problems with combat.

>>11815662
Hot take: The appeal of hard scifi for an author is worldbuilding a realistic future constrained by plausible physics which ends up being the focus of the writing rather than the plot or characters.

Real take: It's a very niche genre within a niche genre, and lots of hard scifi are labeled just scifi rather than something more exact.

>>11815387
pls no bully

>>11815680
That's why the future of warfare is in autonomous systems. Send some big ships in high orbit around an enemy planet, the AI deploys arrays of reconnaissance satellites that form a local communication network with your kill-drones that go after enemy defensive arrays and start dropping tungsten rods on military facilities on the surface. this will ultimately be much cheaper than having manned teams deployed locally to plan and execute

will there eventually be steak on mars?

>>11815692
guinea pig steak, sure. They're the most efficient meat to raise

>>11815690
manned spacecraft will be much better at conducting combat then unmanned spacecraft.

>>11815692
Suer, but the hopes is by the time there's a good human presence on Mars, we'd have moved on to 3d printed foods. So not just steak, but also human meat, dog meat, etc. 3d printed for humane reasons.

how? they are far more expensive, have worse mass constraints etc. it's not like those humans will need to physical fire weapons at enemy ships. spacecraft will never be close enough together for that to be viable. if anything you might have a few manned craft operating the semi-autonomous fleet that is actually fighting the war

>>11815372
i'm no aerodynamics expert but wouldn't less surface area be better? the boosters on some rockets have a gap between them and the main rocket and they are designed so that the tip is right in the middle of the booster leading to air being dispersed equally on all sides of the booster leading to some air going in this gap. that increases the surface area drastically compared to the older soyuz rockets which increases drag. i could be wrong since i don't know much about supersonic aerodynamics or how the stages are

Humans are much better at handling chaotic situations than machines and combat is almost entirely chaos.

>if anything you might have a few manned craft operating the semi-autonomous fleet that is actually fighting the war
That is most likely, fleets composed of mostly autonomous frigates with some manned dreadnoughts to direct them.

>>11815728
There’s more surface area but it isn’t facing the direction of thrust so it’s less important; but being longer does make the rocket more sensitive to wind conditions which is why many US launches are scrubbed

>>11815730
and human vessels won't? I hate to burst your star wars bubble but spacecraft aren't driven manually by humans anymore, and they definitely won't be in the distant future. manned spacecraft would rely on the exact same sensors and equipment as unmanned ones

No, the AI that actually decides what would be the best trajectory to attack the enemy from is very prone to ecm. Humans aren't.

Only to a certain point. Whether that is the price, taste, texture, etc. You're not going to eat a "real" farm raised meat on Mars if it cost $1 billion per lb. You'll just enjoy the 99.9999% same taste/texture/feel 3d printed meat on Mars that cost $20/lb

Juneteenth is an old as fuck holiday, it’s huge in the areas it’s relevant to - mainly Houston, galveston, all the coast east through to louisiana and to some degree atlanta. It’s a dope holiday, it’s literally just fourth of july with more food, more fun, more drinking. It’s not really very political usually, even this year the political stuff is not that big here in Houston

>>11815817
Chickens can actually fly, we've just bred them to be fat and also clip their wings asymmetrically so they can't fly right.

>>11815845
>huge in the areas it’s relevant to
>pennsylvania
Juneteenth nominally celebrated emancipation but really it celebrates the day the last slaves were freed - in houston and galveston specifically. That’s why it’s really only big in the areas I mentioned. Why would it be big in a yankee state?

>>11815855
It’s becoming “trendy” this year for everyone to mention it and act like they’ve always celebrated it. In Houston businesses always talk about it but don’t use it as a PR stunt. It’s so sickening to see the twitterverse use it as a means of virtue signaling, like the celebrities filming their white guilt video in black & white.

>>11815855
>yankee state
we aren't new england up here

>>11815845
That's because it's really a Texas thing. People trying to make it a national holday are virtue signalling hard.

>>11815861
>>11815875
Yeah it sucks. It’s funny because in houston, which has had massive protests and is THE center for juneteenth... I’m pretty sure nothing is happening except the usual block parties. Seeing people with no connection to it virtue signaling is irritating. NGL it’s kinda cool that it might become a holiday in some workplaces. Just another day to get the family together and eat, drink and be merry. Juneteenth is and always has been and hopefully always will be a CELEBRATION.

depends on the stock and feed. If it were properly planned they’d use Aussie cattle since it’s entirety free of mad cow, and why not nip that in the bud from day one? Gravity might fuck with cows a lot, fuck up their muscle development among other things. Maybe it would end up really tender and under developed like veal?

>>11815893
Inedible stock should be rendered nutrient stock for more crop, still your most efficient way to produce protein. Once a colony is large and stable enough chickens will be the first accessible meat item because they're also incredibly efficient. Beef is a retarded, high luxury item, and bugs are unnecessary and unlikely to be sought after.

>>11815893

>>11815912
nobody thinks elon is a conservative, we think he is a libertarian and it's weird to see libertarians pushing far left talking points. might very well just be elon trying to be nice to his workers, but he isn't exactly known for being a soft guy.

>>11815893
There's a difference between eating like that out of necessity and eating like that because Steinberg says "it's good for the environment goy" while he and his parasitic family get to eat high quality beef. Those who choose to think that he's right are literal cattle. I shall only agree if Martian colonization keeps the Rothschilds and other dynasties away

That’s not what juneteenth is at all. Fuck off. It’s literally just a party/celebration, black people rarely even tell white people about it. People are trying to virtue signal with it, yes, but it’s not a far left holiday. It’s over a century old. It’s a shitload of fun. Black people just use it as an excuse to have huge family/neighborhood cook outs. It’s like thanksgiving meets the 4th of july with music. You faggots probably never once heard of it till this year

>>11815988
Sure, for texas it is. But in the context of making it a national holiday, you know damn well it's being pushed by BLM types to further the white guilt/evil white man agenda.

It’s white liberals and democrats virtue signaling, they literally would not be doing this if not for trump scheduling event on 6/19. But Juneteenth is fundamentally a celebration, and a black celebration. Shit even in Houston plenty of white people dont see a juneteenth celebration ever because black people keep it to themselves, it has nothing to do with white guilt. Fuck, Ive been to a juneteenth cook out as a white guy and they do not give a stone cold shit about white guilt.

I've been in these threads since before SpaceX was even trying to land boosters you reek of election faggotry and can't help but inject politics in here because of that Elon tweet

>>11816052
The first stage used kerosene, but the second and third stages used hydrogen as the fuel. Which increased the payload capacity of the Saturn rockets. Hydrolox is bad for booster stages, but great for upper stages.

>>11816057
How would hydrolox help though? Doesn't hydrolox greatly increase tank size due to low density?

>>11816069
Yes, but not for upper stages, which are much smaller. The booster stages are the bulkiest motherfucking parts of any rocket design and they get exponentially larger when you go full retard and pick a hydrolox booster stage.

>>11816064
>Not really since there are many instances of white people violently resining arrest and not getting immediately shot
African americans by and large commit much more crime as a group then any other racial group in america.

>>11816083
Gotta remember, Apollo CM needed a tank of a certain size too. There'd be an awful lot of empty space if that upper stage was RP-1 with roughly the same burn time. Just look at the N1 lander for example. That was an all kerosene staged lunar rocket design. Skinny ass one man lander compared to the fairly comfy 2 man LM and roomy 3 man CM design.

Why do you think racism is still a demonstrable large-scale issue when it’s measurably not? Some people are racist. That will always be the case until the government invents literal mind control; and blacks have much more to fear from eachother than some random officer trying to do his job.

>>11816163
The early research into liquid fuel rocket propellants didn't see any advantages to methane over kerosene, so they broadly ignored it. Later research revealed that the fuel's mass density could be considerably better than the old studies showed with subcooling, and the combustion dynamics of methane allows a much higher portion of the engine cycle's theoretical potential to be realized in practice than other fuels like kerosene and hydrogen.

>>11816163
Kerosene was more established and usage was easier. Hydrogen was harder to use but offer much better Isp. Methane was seen as the worst of two worlds.

Your question made me think, and I found this interesting

>>11816163
Because it has a lower specific impulse and that's what the US chased at the expense of larger more challenging tanks?

STARLINER is the only spacecraft worthy of human rated flight.

It is though, even when not talking about police brutality.
Off the top of my head there's the disparity of black vs white weed possession arrests

>>11816163
This is a really good question. All the replies are so interesting. I take it methane just looked like shit on paper, but with modern technology it’s probably easier to store and get the most bang for your buck, AND it can be found anywhere which is a win when it comes to refueling

Black communities have higher crime and are therefore patrolled more; therefore there are more weed arrests. I’m a libertarian so I say just legalize it.

why dont russians just make their own spacex
how hard can it be

>>11816205
I wonder if they could convince the Indians or Chinese to work with them, but considering poorly those joint projects go.... To bad the russians botched any chance of working with ESA.

>>11816210
looking really fucking LGBTQ so you get more funding

>>11816214
I don't think Russia has the knowledge base to push ahead like SpaceX without great expense, and Russia is abit strapped for cash.

>>11816210
I think in the case of Cygnus the PCM is from Thales Alenia Space which makes ISS parts so it was easier to "certify."

>In November 2014, it was announced that one part of the URSC charter is to increase the relative wages of those who work in the Russian space sector in order to attempt to counteract the low productivity and brain drain that has been hindering the industry. The average space industry employee was then paid ₽44,500 per month (US$900, or approximately US$10,000 per year). URSC projected that the Russian space sector would employ 196,000 people by 2016. URSC's publicly-stated long-term goal in late 2014 was to increase productivity of the space sector, threefold while doubling real wages by 2025.[13][needs update]
>Despite Russian state efforts in the reorganization, two more Proton launch vehicle failures occurred in 2014 and 2015.[14][15]
hehehehehehehehe

>On 28 January 2017, the Russian government announced as a result of the investigation into Progress MS-04 the recall of all Proton-M 2nd and 3rd stage engines produced by the Voronezh Mechanical Plant (common to the failed Progress flight) including the disassembly of three completed Proton rockets and a three and a half month suspension of flights.[10] An investigation had found that engine parts that were supposed to use precious metals had been substituted for cheaper alternatives that were unable to resist high temperatures as well as finding that production and certification documentation were falsified.[11]

>>11815397
for the Soyuz, it bears load at the tip of that tank, so it is pretty structurally strong. (And the internal sustainer "stage 2" is weirdly reverse tapered!) The N-1 was conical for a completely different reason: to fit the successively larger spherical tanks as you moved down the rocket.

how long until russia is stuck buying rides on starship to get anything to orbit

>>11815610
Europa Report was pretty good for the tiny budget it had.

>>11816233
They won’t ever do that. I don’t even think they have the ability to set aside their pride and buy starship launches. Even if elon gave it to them for $2 million

Anyone want to guess why the Indians this in their space capsule?

>>11816284
That may be more “futuristic” but it’s expensive as hell. Cheaper is better

>>11816293
Saturn V didn’t have cork because there wasn’t enough of it
Unless SpaceX has a 10000 cork orchard in the back yard, I doubt that they could use it on BFR

Will never happen. SpaceX won't fly people on Starship until they're absolutely sure that it's safe enough to do so and 2024 is too soon for that.

>On 14 February 2008, U.S. officials announced the plan to destroy USA-193 before atmospheric reentry, stating that the intention was "saving or reducing injury to human life". They said that if the hydrazine tank fell to Earth, it "could spread a toxic cloud roughly the size of two football fields".[26] General James Cartwright confirmed that the United States Navy was preparing to launch an SM-3 missile to destroy the satellite, at an altitude of 130 nautical miles (240 km), shortly before it entered Earth's atmosphere.[1]

>U.S. officials denied that the action was intended to prevent sensitive technology falling into foreign hands[1] and also denied that it was a response to the 2007 Chinese anti-satellite missile test.[29] This was not the first time the United States shot down one of its own satellites; the Air Force had shot down a satellite as early as 1985.[30]

They were first in everything but manned Moon missions. Are you saying that just hoping to bait someone with your retardedness? While it is truw their bureaus and industries were fighting each other while grossly ignoring cosmonauts safety, that is a bold senseless statement

>>11816386
>for deep-space missions
When you combine expense with the fact that the gap is closer in reality than it looks on paper, methalox is still better for going anywhere you reasonably want to go with chemical rockets. If you really need more you need to be looking at non-chemical means as the gap isn't so huge that the capabilities are wildly different.
The one exception might be if we can't secure good carbon deposit sources on the moon, then hydrogen ISRU might make sense in lunar infrastructure specifically. Or it might still end up being better to ship carbon to the surface for partial-ISRU methane because of how stupid hydrolox rockets are.

KSP but designing ICBMs instead of spacecraft when?

children of a dead kerbin when?

>>11816421
Now. There's nothing stopping you. On a side note, with the new fuel/engine exploit you can make some crazy stock space torpedoes like in the expanse. It's fun crashing into the mun in 3 minutes from launch on a continuous 100g burn.

>>11816425
yeah but it's not the same without a proper WW3 mode and ABMs and shit trying to knock out your missiles once you finish designing them
