Reminder that BO will be discounting New Glenn in order to get their launch cadence up and they're not going to try to get all of their R&D cost back. At 60 million per launch, as estimated by CNES, it would actually be pretty competitive as the best alternative to Starship.

How many people who advocate for O'Neill cylinders really just mean very large Von Braun stations? At least when they speak of them in the 21st century?

>>12800949
O'neill cylinders and any other kind of long term space habitation are not something for before colonizing Mars, they're for after Mars is colonized and all the primo land is developed. Most places in the solar system can't be easily described in terms of square kilometers of useful area because they don't actually have useful area, with problems like low resource availability and rounding error gravity. Long term space habitats are for when Mars is developed and you're trying to mine or develop these.

>>12801466
If they launch at $5/kg they'll have no problem filling out their maximum manifest of like 7 flights per year a peak output. So that's great, lol.
Also subsidizing launch costs entirely on the back of the CEO's bank account rather than the actual launch costs seems illegal in some way. If it were international it would 100% be dumping, I'm not sure if dumping laws apply within the nation though.

>The best historians of the Ordo Historia believe that humanity first left its origin planet Earth about 3,400 years ago. Since then, we’ve spread across the galaxy on a fitful wavefront of colony ships, frontier worlds, robotic terraforming projects, and DNA-synthesizing probes.

>Today, mankind is smeared across a region of the galaxy about 1,200 light years wide. Our best models indicate that there is a general trend towards greater population density towards the center of the this region, where the stars were colonized earlier. At the edge of known space lie the rimworlds, drifting alone with few inhabited neighbors, mostly unvisited.

>We’ve created many new technologies, but despite milennia of effort by our best human minds, and even the most powerful archotechs, nobody has managed to make anything go faster than light.

>The lightspeed barrier separates us. Because travel times are so long, planets tend to be very disconnected from each other socially and technologically. The next star over could experience a catastrophic war, and you wouldn’t even know until ten years later when the news reports arrive. If you’re unlucky, you’d have already launched a journey towards that now-destroyed planet in a ship that cannot turn around.

>Many attempts have been made to create pan-galactic empires and republics. And some have worked, for a time. In the core worlds, an old, stable culture can create an interstellar empire of a few systems. But there are no great galactic empires stretching across the galaxy, for the same reason that no ancient empire of Earth held more than a sixth of the planet: one cannot govern people who are years distant by all means of travel and communication.

>>12802158
Imagine when great britain has access to starship launches but europe still has to pay 1000x the price and wait months to launch even a single payload. Gonna be so kek worthy.

I strongly suspect there are many starship clones being developed in silence which mostly wait for musk to finish his so they can benefit for as much as they can from his r&d it's the only thing that makes even a bit of sense. If not it means that me personally am smarter than every politician scientist and engineer outside of spacex and although I'm a pretty smart guy I doubt I'm in the top 0.00000000000001% I'm probably closer to top 0.00001

> So most people never travel between stars, and if they do, they do it once or twice, because each journey means leaving behind a life that you cannot return to for decades at least. With a few exceptions, each star system is essentially on its own.

>Mankind never discovered any truly alien lifeforms. However, given the ways we’ve changed ourselves, and created new forms of biological and technological intelligence, the universe is full of beings as alien as anything ever imagined.

I can't see how this is any different than what happened with the Falcon 9 which still has yet to see a real rival due to how slow their competitors move. Copying a rocket that is already developed puts you too far behind, they need to get ready to build something like a 16m wide version of Starship so they can match SpaceX when they get to that point.

It's not like expendable rockets either where you could copy them years later and have the same cost as your competitor, SpaceX has a huge cost advantage because they'll have the experience in reusing Starship. If SpaceX has an average Starship reuse of 20 times and your clone can only do 10, you're fucked. They'll also be further ahead in their production curve and will be able to make them cheaper than your clone.

>>12802165

No it just means the clowns are running the circus, which has been true for a long time now. EX: The shuttle was a design by committee boondoggle. The Russians, seeing this, knowing that it made no sense... went ahead and made their own anyway. Traditional space programs have talented engineers led by politicians and talking heads.

>>12802199
I tried looking it up directly (I know I read it somewhere), then I went with the isotope charts on Wikipedia.

31Si trace 2.62 h β− 31P
32Si trace 153 y β− 32P

35S trace 87.37 d β− 35Cl

Sulfur gets you chlorine. Unless you know something more than just shitposting a chunk of the PT with no context.

>>12802211
Alright nuclear chemistry weirdos there a way to force this process?

>>12802211
Oh wait those are just the "stable" isotopes. Silicon still has a lot more that make Phosphorus than Sulfur. Fuck me, I gave it a try, not gonna murder chart this shit out with index cards and string.

>>12802210
russias shuttle kinda made sense though. it was autonomous for one. and energia with another 10 years in computer advances could be made reusable.

>>12802227
If you're a levelheaded engineer and you look over and see your competitor pursuing a PoS with broken fundamentals, you don't go halfway and make a better version, you completely sidestep him. Energia was good but they could have done better cutting out the sidetumor, it all would have all fallen apart eventually but still.

Is there some Raptor guy who smacks everything together or is this more of a machine guided process? What is ideal?

>>12802211
Sulfur also can get you phosphor. But these silicon and sulfur isotopes that give phosphor, don't seem to be found in nature? I can infer that getting these isotopes could be possible with expose them to radiation from nuclear plants for example? Sorry for being brainlet

>>12802237
John Henry Raptor lives in the hot depths of a C*li faultline where he forges every artisan engine by hand

>>12802235
thing is in the 80s the best you could hope for (and i'm surprised it even worked) was autonomous glided landing. doing hoverslams on even just the boosters let alone human rated vehicles would have been beyond anything possible at the time.

>>12802195
Price is far, far from being the only factor in choosing a launch provider

>>12802243
The only thing the Shuttle did for reusability you can't do with a dinky capsule is bring the main engines back, which cost so much time and money to put back in operation it probably wasn't worth it. IIRC the Buran cut that part anyway and just took RCS control, making it practically a big glideback equivalent to a capsule.

>>12802239
Yes that's the whole point, you irradiate them into the ones that will decay into phosphorus.

>>12802259
there was the autistic requirement that it could capture and return a satellite which a capsule couldn't do. the thing could barely land empty i'm not convinced it could land carrying a 20t sat in the bay.

>>12802165
>I strongly suspect there are many starship clones being developed
There aren't any - nobody actually believes it can be done. Whatever meme projects you see are just paper gliders or other nonsense that won't see much beyond few hours of intern work to morph it into CGI at best.

Think about it:

>superior payload to Saturn 5
>fully reusable
>cheap
>all-in-one vehicle for the entire solar system - it can land on other celestial bodies
>habitable volume near identical to the international space station
>developed in under 25 years with <trillion $ without grueling world-wide government effort

Absolutely nobody out there is going to see it coming until the first few thousand people are alive and kicking on Mars. Even then we might see some peculiar defensive psychological reactions.

>>12802244
t. old space

Price is quickly becoming the sole factor for the majority of commercial payloads. Orbit availability and time concerns will be completely remedied by rideshare and tugs. Roughly 5 Starship launches can launch the entirety of the payload weight sent to orbit in 2020 at a price per kg of a fraction of any of their competitors. Hell is coming for most of the other providers.

>>12802244
You want to see how Ariane actually stacks up on those far, far more important factors? Their mission success rate is slipping, they don't launch as often. The sole advantage Ariane has to fall back on is protectionism.

>>12802265
>nobody actually believes it can be done.
And if they were doing it they literally wouldn't be able to hide it. You either do it in a field like SpaceX or you build MASSIVE holding facilities.

>>12802243
Hoverslam - probably no.
Hoverland, however...?

For one, they did use that method to land people in the 60's and of course some tests were done on Earth before plopping them on the Moon...

i don't disagree. however the moon landing is comparatively easy compared to smashing into an atmosphere and not hitting the ground like a bullet. the lem was piloted, i don't think it would be possible to pilot something like starship with the kind of electronics available before the late 90s.

>Many people in the field of science are aware of the Alcubierre Drive and believe that warp drives are unphysical because of the need for negative energy,” says Lund University Astrophysicist and Scientist at Applied Physics, Alexey Bobrick. “This, however, is no longer correct; we went in a different direction than NASA and others and our research has shown there are actually several other classes of warp drives in general relativity. In particular, we have formulated new classes of warp drive solutions that do not require negative energy and, thus, become physical.”

That is different, the government doesn't buy energy or farm products at absurd prices or fund almost the entirety of the companies that produce them but would otherwise be extremely unprofitable. If ULA received the same level of subsidies as they would get if they were farming corn they would have been bankrupt years ago. As it stands now they're being slowly phased out and their lobbying power is waning, SpaceX now gets the majority of military launches and the next contract will be even worse for ULA.

>Is it so certain that even orders of magnitude drops in cost will yield an explosion in business?
If it doesn't it will be much worse than their competitors than SpaceX. SpaceX will be launching frequently anyway to put Starlink in orbit and to send ships to Mars, they'll be improving their cost regardless of how much profit their launch business in turning and they will be perfectly positioned for when business picks up again. Every other provider will basically be starving and dependent on the government. I call it the great starvation period that will go on until the greatly lowered cost of access to space is realized and we start to see shit like space hotels instead of just more satellites.

>>12802354
>aren't they struggling to fill capacity as it is
The capacity SpaceX is struggling to fill is their OWN capacity. They outlaunch the market. That's why Starlink exists.

Food prices would rise to the point where most farms will be fine without subsidies. The oil industry is closer to rockets as domestic producers are being greatly outcompeted by cheap Saudi oil that they have no chance of beating on price. It's also similar because subsidies will stop for it as well as electric cars greatly decrease oil demand and quell national security concerns. ULA will die before ArianeGroup because SpaceX is American, "we need multiple providers" is lobbyist COPE.

There isn't as much money sloshing around because the Euro isn't the world's reserve currency. Once the dollar loses that status, and it seems to be on the way, the US is going to find itself subject to the same financial realities as everyone else. As we get near that I predict war of one kind or another, I mean that's what some people theorise is already underway with coronavirus, the repo market weirdness and titanic money supply brrrr going on

Why did they go with two stages instead of 3? I guess it's because SRB's have huge thrust? Also this core stage is comically big. I hope SLS actually does launch at least once so we at least get to see it

>>12802428
he has a point. there seems to be something in modern european mindsets that actively despises ambition. do just enough to wrap themselves in a blanket and hope the rest of the world goes away. like the world stopped sometime mid last century and rely on inertia and economic size to carry on through, which is a policy that is failing everywhere.

why did NASA decide its goal for the first half of the 21st century was to recreate the Apollo program? Is landing a woman/minority on the moon to right any perceived "wrongs" from the Apollo program that important and worth that much time and money?

The EU's strategy is to lock up their own market tight and then use access as a weapon to strong arm fledgling competitors into adopting its standards thus lowering their competitiveness. Look at the total spaz out over Brexit for the classic case. Problem for them is Europe is declining in importance so they can no longer dictate terms. Even Vietnam can make passable electric cars. What's the point of Germany again? At least France has great food and scenery to fall back on

so you're saying if NASA had tried to use Apollo tech to land a man on Mars in the 70s there's no way a LEM could have been landed on the surface like it did on the moon?

>>12802421
>How come there aren’t really Euro space companies?
Europe is a dying continent with regulations stopping anyone willing to build a great new thing there is a reason why there is no tech industry here

they're pretty good at getting the monthly checks to the refugees, they always arrive on time

it's almost juche, with any outside trade having to be conducted on their own terms.
problem is as their wealth declines and they're left with tourism and some manufacturing mostly subsidised and serving the domestic economy they aren't in a better place than asian countries, and will have lifestyles and global standings that compare.

>>12802510
Not him but the lem is fundamentally different than a starship. You might be able to get away with landing a SS on the Moon, but you would need a lot of fuel. The LEM engines burned for a long time an was designed so test pilots could slowly put her down. Starship (at least in terms of Earth and Mars landings) is designed to strategically fall out of the sky with pinpoint accuracy and then fire its engines and flip last second—a maneuver too complex and dependent on too many factors to do manually.
As a side note, NASA's plan for a Mars landing essentially uses a LEM-like lander (sort of) that could probably be put down manually? But they would never do that now. Technology and artificial landing software has gotten too good and it would be stupid to rely on human hands to land it

>>12802510
it would have taken a load of reengineering and a pilot with balls the size of martian moons and a huge amount of skill.

>>12802421
There are many, including private companies that sell parts to NASA etc. Europe just doesn't have a religion around tech giants because the continent is capital poor, so they rely on leaner methods to survive rather than investor hype bloat.

Any achievement by white Americans is an achievement by Europeans. Remember that.

>>12802552
There are. In particular Berlin is trying (and failing) to be silicon valley.

I mean...I'm guessing your not in the Aerospace research comminity. A lot of research and engineering for both NASA and private American companies is done at small European companies like OHB, ArianeGroup (Safran and Airbus merger) etc. The ESA obviously sucks, but the DLR tries its best with the limited budget is has. Europeans know to stay in our lane. We can't compete with US capital and even if we could the US companies would quickly take away our toys anyway like what Boeing did to Airbus. Europeans have ambition tempered by limited resouces. We are still a very povo continent and so we try to fill niches instead and hope to expand one day. The end result is that we get the same market share as many of the American meme companies get, but without the media hype that pumps expectations for future IPOs which don't matter here because the population is too poor to have retail investment.

That’s such a meme, Europe has an abundance of resources and wealth

>>12802674
Ehh it's easier for US states to compete and try to all individually contribute to big projects, even shit like SLS. The EU kind of sucks because they are all individual countries and not only do you have language barriers but you run into the problem of each country wanting a piece of the pie, clawing at eachother for contracts, etc. The USA is just way more unified than a union of Euro countries

Nah this is a cop out. Russia and China's currencies aren't reserve currencies either. The truth us that the EU was very much on course to have the type of economy America has. A strong middle class and consumer base that can afford to invest as a hobby. I got even better when Germany started getting rid of socialism in the 2000s. But of course, it all got fucked during the expansion of the eurozone which flooded the labour market and depressed salaries. As soon as Europe started recovering from Polish migrant workers businesses start funding the importing of legals, illegals asylum seekers and crashed the labour market even more.

Europe is still being held back by old money institutions that don't want a strong middle class economy.

I cannot name a single European tech company, or service that I use, and I've never owned a product made in Europe. Capital that would otherwise go to US companies would flow into European companies if there was anything worth buying, global investors just want successful companies with growth potential and the regulatory issues and lack of productivity of Europeans kill it for them.

It is literally not? Even with the UK now gone it's had a lower GDP than the US since the Trump economy.

>>12802688
I didn't mean natural resources (which aren't worth shit in a modern economy). Europe will take a while to build up niche tech companies etc. which will increase the venture capital pool. Europeans need new niche markets to fill. If WW2 didn't happen it would be a different story. Germany's IP wouldn't have been looted for a decade and maybe Konrad Zuse's company instead of IBM would've ruled the tech industry. The internet boom could've benefited Berlin and Munich startups.

Europe fell behind the US irreperably, but the world economy isn't a zero sum game, it is trying to grow in new niche sectors.

>wealth

Yeah, but it's old wealth and they only invest in established companies because they are greedy cunts that hate the idea of other euro families getting rich. There is precious little new wealth in Europe and that's part of he problem.

>>12802692
That's bullshit. Israel built a wall and stopped Egyptian Arabs from streaming in 40 years ago. The EU didn't want to defend its borders because our elites wanted a new slave labour pool, we can't blame the US (or this new meme of climate change) on that.

>>12802728
>I've never owned a product made in Europe.
A big part of this is trade barriers as opposed to Europe not making anything. There are hardly any US built cars on the roads in Europe, but that doesn't mean they aren't being built. Also please show me your mobile device that isn't reliant on ARM

>>12802730
You funded Israel which our bribed our politicians to let them in. Let's move forward from the blame game shall we?

>>12802752
>It is literally not? Even with the UK now gone it's had a lower GDP than the US since the Trump economy.
possibly. idk last gdp figures i saw (and this was probably 2 years ago so the uk was still there) has the eu slightly above the us. the point was they're comparable so there is no reason the eu shouldn't with free movement of capital have the same dynamics of innovation that the us has.

>>12802752
>There is precious little new wealth in Europe and that's part of he problem
It's frightening really. I read somewhere that a big percentage of the North West UK economy is literally just the NHS. So just sick people on the dole and an army of medics paid to look after them. Sometimes I'm amazed the UK economy world at all because huge chunks are just money magiced up from nowhere. Fuck knows why the rest of the world trust the pound

I don't know if "reinvent" word can be used, but he certainly revitalized it. The drive to reusable/lower cost/the private space sector is entirely due to Musk. Heck, in 2010, American had 0% commercial space market. By 2019, we had 70-80% of the market, thanks to SpaceX.

Before SpaceX/Musk, space industry was a stagnant and on a declining trajectory. That much is certain.

The EU GDP is very misleading. There is very little free capital and best old money companies are being looted by the CCP and bribed politicians. It will drop very quickly soon.

We are trying to attract US investment of course, but we literally keep having our IP stolen by China. The Netherlands had the best transmitter tech in the world for example, but the corrupt EU literally forced them sell the tech to China. And that is another lost opportunity to bring silicon manufacturing to the EU. Besides hacks, our leaders are selling us out (and they are cheaply bought).

>>12802787
It gets worse desu. Because administrators don't want to pay local nurses snd caretakers a fair wage, most of them thirdworld people imported through various schemes are working on subminimum wages (they accomplish this through various schemes like forcing them to sign housing contracts in a shitty barracks that eats 80% of their wage or just outright illegal employment).

After these workers obtain citizenship, they quit their shitty jobs and live on welfare. Then adminstrators repeat the cycle and import new third worlders. Meanwhile we have fucking 40%+ youth unemployment in Spain. Young people can't work and their parents' tax money is being used to fund their replacements.

Our tax money is being funneled to an ultra wealthy elite who will die before the Eurozone implodes and their wealth becomes worthless anyway. This shit's coming to the US very soon too though.

If you have insurance, you already pay for it through them. Unless you're suggesting everyone on your insurance plan is a fit 25 year old man who does not plan to get married and incur no family responsibility. By the design, if you have insurance, you are paying for those obese people. 70% of Americans are obese, therefore, 7/10 people in your group is obese on average.

Reusable boosters and rockets are a big deal. But the tech for vertical propulsive landing has been around for ages, though only in tech demos and it's impressive they were able to implement it. Other than that the Falcon9 (and heavy) are pretty standard and well made. A solid rocket ahead of the competition by a decade (or rather everyone else is lagging decades behind).

Now the starship is on a whole different level. It (booster+upper stage) will be the biggest motherfucking rocket ever built. It has a bigger pressurized volume than the entire ISS. In fact it would be cheaper and better to just drop the ol' ISS in the ocean and send a bunch of modified starship up there.
But you would be wrong to think it's just a stupidly oversized rocket. No this can bad boy can not just take off and land on Earth, it can do this on the Moon and Mars. Now if you don't know that's a pretty big fucking deal. If he succeeds they'll even put NASA to shame. It is estimated it could deliver between 100 and 150 tonnes to mars, that's the equivalent of over 100-150 Perseverance rovers, or about 3 adult male sperm whales. Whichever you prefer. So how does it achieve that? Yup, orbital fucking refueling. Now this is the biggest game changer of them all.

combustion chamber design, eh you're on your own but you need someone with a lathe.

>As he grew increasingly uncomfortable, Shepard radioed the launch centre to ask to be removed from the capsule in order to let nature take its course.
>Werner von Braun, the German born rocket scientist in charge of the launch came back with a firm no. The last thing he needed was for his rocket to be ready but with a missing astronaut.

>So Shepard had only one solution left to him. He radioed again – could he pee in the suit? Again the answer came back no.
>Inside the suit Shepard was attached to four electrocardiograph pads, a respirometer and a rectal thermometer (ouch!). These would record his vital signs and how he reacted physically to the changing conditions of the flight.
>Urine inside the suit would cause short circuits and possibly even shocks that could injure or incapacitate Shepard.

>The increasingly desperate astronaut radioed a third time. He had to go; could they switch the medical monitoring off?
>There was a delay as von Braun and the launch team held a discussion before finally cutting the power to the electrodes and giving Shepard permission to relieve himself.

Simple and elegant unlike raptors which will get anybody nowhere ever

Just letting /sfg/ know I have an old issue of Astronomy magazine in one of my crates and it had an article on "terraforming" the planets and even gave a detailed account of how much water/O2/N etc needs to be dumped on the moon to turn it into a comfortable shirt-sleeve environment ie 1bar/70 deg F and inb4 as I recall the low gravity necessitates a lot of atmospheric mass (like more than the Earth's even) and this provides a great deal of protection from radiation/cosmic rays etc. Would be nice to have a low-g vacation spot just a few days travel away, and I'm hoping that /sfg/ will help me push for this to be NASA's follow-on to the SLS/Artemis program (like an Artemis-Applications program) as I think it would be cool if we made it happen and very beneficial to vacationers everywhere.

It begins

>>12802165
This. There's a lot of documentation on raptor engines and starship and heavy booster diagrams. An aero space engineer can do a lot with those. For one I am sure copies are being made in China, with chinese engineers looking at what progress is being made and waiting paciently for a serviceable design to prove itself. I mean starship is a simple design itself, and with the technology to 3d print entire engines, copies will florish.

>>12803078
Where is this engine from
what material is the combustion chamber and the bell
what does the thing with the airgaps around the combustion chamber do
whats the material under the metal sheet where the engine is narrowest

>>12803078

the raptor has a lot of weird stuff to satisfy it's many requirements. for instance, iirc, it has a whole helium system that it uses to spin up it's turbines when starting up. most engines just use the tank pressure.

>>12803079
loads. literally hundreds. if you're looking more at motors rather than sticking a store bought solid in an airframe then start with hybrids. they also have the advantage that they're not classed as explosives (the US doesn't care, but then that's why they have rogget companies).

>>12803078
Sensors. Stuff to keep the sensors going. Stuff to control things from data sent by sensors. Fucking sensors, man.

>>12803078

why is there an air gap between the combustion chamber and the cooling jacket?

>>12803101
not that Anon, but thanks!

>>12803078
that's pressure fed and 90% of a rocket engine is the turbopump.
>>12803096
>what does the thing with the airgaps around the combustion chamber do
presumably takes the oxidiser and passes it around the chamber to cool it.

>>12802830

>>12802412
It's my understanding that the paper basically proposes various sets of distributions of mass and energy that would, if general relativity is correct, create a sub-luminal warp bubble. Asking from what materials such a thing would be constructed shows a fundamental misunderstanding of the purpose of the paper.

>>12802974
As soon as you get sick, the insurance company should have the right to kick you off. Excellent plan.

>>12803101
Would compressed air work as oxydiser for a hybrid? I want to make a self landing rocket. Also do you have more videos with liquid engines

Just a reminder, the whole "space is for everyone" thing and the cooperation between countries will drop down drastically when the space boom happens. Once its a money making endeavor countries will be left behind so please write your governments to push for space

>>12803119
It would, but you'd need a either a lot more of it or higher pressure for the same result.

>>12803119
yes it would but for reasons i can't remember the name of nitrous is preferable because it pressurises itself, where as gox drops off as the tank empties. the tank is also much heavier (anons pls jump in here i know one of you knows this).

It's a really long story and actually involves an American court "putting us in our place" with an anti-trust breakup that ended with the forced transfer of tech to the Chinese component of the company. About half the people in the West in positions of power are bought out by the CCP. We need to bring back the death penalty for corruption.

>>12802199
You let silicon absorb a neutron and become a heavier isotope. This isotope is unstable and the neutron decays into a proton, turning the unstable silicon atom into a stable phosphorous atom. Depending on the silicon isotope you're starting with you need to add one or two neutrons, which you can do just by having silicon exposed to neutron flux from a fission or fusion reactor. You can also use a proton beam from a particle accelerator to generate a neutron beam to accomplish the same thing.
