From what I've read he managed to deliver the wrong kind of ventilator. Ones that are used for sleep apnea.

>>11567221
Elon clarified that is what they asked for and this was confirmed by a hospital. According to this side of the story. It's essentially too late once their on intensive care ventilators and these ones prevent the need for intensive care ventilators.

Media ofcourse spinning it for views.

>>11567120
The boomers within Boeing who were tasked with bribing politicians died from corona.

>>11567221
No, you need these vents for people with slightly better conditions. If there was a war and Elon donated his rockets to military. They military won't say "NO ITS THE WRONG SHIP!!! WE NEED WARSHIPS NOT ROCKETS." They need all types of ships. Rockets have their use in launching satellites for war, or can be modified to carry nukes.

His vents were meant not meant for extreme cases, but for milder conditions. Mild patients need vents as well, but they don't need the best ones. Those should be reserved for extreme cases.

>>11567604
You'd need access to a lathe and probably a mill if you want to make anything approaching a good one, but yes. I'm going to work on one when I actually have a workshop/garage. Small lathes aren't too expensive, and if you live in/near a decently sized city there'll be a maker space that probably has a mill.

>>11567120
Boeing's MO for the past few decades has been to stall in R&D hell forever because that's more lucrative than actually delivering products, while their civilian side shits out more 737s. Now there's a hard-and-fast deadline of "astronauts back on the moon by 2024" and the 737 Maxipad is falling out of the sky, so both halves of their little scam stopped working.

Needlessly endangering animals is wrong.
Use a Christmas ornament or something instead.

wow what an epic derailment, sincerely the only space news i want is "SPACESHIP IS FLYING" like , literally i dont care for anything else, expendable shit can go fuck itself, any other news about any other rock, even news about dragon are shit. all we need is that starshpi flying

its like inmortality, do it
do it now
why is anyone not working on anyhting esle than that

once inmortality is done then everything else is instasovled, you have infinite time to think about it.

same thing with starship, once its done anything space is instadone as prices skyrocket but down instead of up

>>11567095

>>11568005
Actually, there's a huge contradiction because your first world lifestyle hurts thousands of animals each year without you consuming animal products directly. If you truly gave a fuck about not endangering animals, you would live in a cabin and grow all your own food. That would be the only way not to endanger animals by proxy, but you refuse to do that because you don't give a fuck about animals, you just need a reason to feel superior to others despite being inferior in all other ways.

Not even close. I've always done fairly well with women because I'm fiercely independent person who won't play to their tricks. Often times they pursue me instead because they think I'm disinterested in them and that is signaling that I'm a higher quality mate. Not to mention that the original argument is so obtuse anyway because psychopathy, not that I have it, is positively correlated with a bunch of attractive features to women.

This isn't a formal debate, retard. Your whole argument is ad hominem and association fallacy, trying to craft allegations that I'm endangering animals out of moral wrongdoing when I wasn't the person who tried sending a frog to space. I just support it because I'm not some joyless faggot and I can see that the humor is worth the slight harm to a fucking frog.

That also isn't a nirvana fallacy since my suggestion was not unrealistic. I have a cabin, grow some of my own food and hunt animals. I guarantee you that my total harm to them is a fraction of yours despite consuming animal products. It's not unrealistic to suggest that people who claim that they are not endangering animals actually not endanger them instead of writing hypocritical bullshit on the internet and literally crying about a frog instead of fighting a real issue. You are everything wrong with vegans and I would love to see you get torn apart by an animal.

>>11568194

>>11568157

The vehicle would be so fucking massive that >>11568193 or a similar sea-launch vehicle would be the only viable option. Personally I'd go for a design with mid-mounted motors on the sides of the first stage that protrude just above the waterline when the vehicle is floating.

Even if there is never a demand for launch vehicles that massive, I can legit see a demand for a class of launch vehicle specifically for habitat construction.

>>11568228
Why not just use smaller launch vehicles carrying raw materials and assemble them in orbit? Like Legos

>>11568233
Like the Space Shuttles did ISS?

>>11568199
>Humor is not worth the life of any advanced lifeform.
Yes it is. Have you wasted time online watching something you found funny? You were consuming energy which if often sourced from petroleum, something that needlessly kills countless animals each year. You traded your enjoyment for their deaths without a second thought. Have you watched a video about a funny cat? Cats have contributed to the extinction of 63 species of birds, mammals, and reptiles. Pet owners are directly fueling this destruction and you're supporting this by watching their content.

The vast majority of vegans never do anything besides wag their finger at people to feel superior and go about their day, believing that not eating animals is the same as not hurting them, it's complete bullshit. You hurt animals all the time, you don't have the right to decide that discombobulating a frog is cruel when you're feeding your useless pet meat products and using plastic. Your moralistic fallacy is so arbitrary because it isn't based on anything but the stupid belief you're not hurting animals when you are.
>>11568205
Try going back to R*ddit. Better yet, try killing yourself and save countless animals, including humans who will no longer have to deal with the idea that such a worthless whiny faggot is stealing breathing the same air as them.

>>11568233

The quickest (and most structurally sound) way to build a torus would be to have the segments prefabricated on earth, kind of like curved airliner fuselages but with outside space-frame truss structures that support all of the structural loads so that the pressurized vessel doesn't have to. Outside the space frame would be multipurpose shielding that protects against impacts from debris and radiation.

I've been brainstorming what could become a standardized system for constructing tori based on my imaginary replacement station for the ISS. Only the torus assembly would rotate and the rest of the station would remain fixed, so that docking spacecraft would not have to perform awkward maneuvers. The torus of my imaginary "Olympus 1" station, would have a chord radius of 125meters and have 2 decks. The torus assembly would be composed of some 144 modules joined together with a cross section of 6 adjacent-joined modules, 3 per deck and 24 per circuit. The 3 module-cross section on each deck would be composed of 2 "room" modules joined to either side of a narrower "hallway" modules. In all there would be 24 hallway modules per deck and 48 room modules per deck. The torus would have 3 spokes arranged 120 degrees apart and 6 transit elevators connecting to the room modules on the top deck. The main rotational support must be from a support column between each of the 2 elevators per spoke, and not the elevator tubes themselves. Each of the hallway modules would have emergency bulkheads that automatically close in the event of a hull breach.

Pic related is my shitty mspaint layout of the torus. I'm still trying to decide (by color coding) which modules should be assigned to which function.

>>11568243
Yeah, but on a smaller scale. A space station people actually live on could be so big that you’re launching, as you said, payloads that weigh a thousand tons or more, but you could instead launch smaller payloads full of materials like insulation, bolts, furniture, beams, wiring, lightbulbs, etc, and assemble the whole thing in orbit. It’d take longer, and I’m sure lots of small doodads could get lost and float off, but you’d avoid the R&D of constructing a fuckhueg launch vehicle.

Supersized TSTO KeroLOX first stage MethaLOX second stage, steel skeleton, steel skin, steel tanks. Tankheads created by a supersized dishing machine out of single very large pieces of alloy, body created with large single sheet rolls from a similarly supersized steel roller. Simple welds will be performed by specialist machines, expensive to design up front but they'll pay for themselves with consistency and speed, human experts will perform inspection as the weld progresses and then they'll be cleaned up. Engines will utilize the FFSC cycle and be designed to have as many common components as possible in engines which burn different fuels, and optimized by evolutionary iterative algorithm to use the minimum number of components, this will simplify manufacture of them as much as safely possible. Instead of one giant single chamber engine as the Sea Dragon would have used, this rocket will use clusters of engines as large or maybe even slightly larger than the F1, if they each develop 7000kn of sea level thrust then only 50 will be required to get it off the ground, a 20m diameter could probably fit up to 60 3.7m bells in a 1/4/8/16/32 arrangement. Tanks will be autogenously pressurized as opposed to using a third inert pressurant gas like Helium. Instead of single block fins multiple fins on each side will be used, RCS will use common bipropellants to the primary rockets, first stage will return via boostback burn and use drogue parachutes to help reduce it's speed to conserve propellant, second stage will perform a belly flop return. The rocket will take off from and land at permanent pads constructed of several oil rig like platforms fused together set out in the gulf or off the coast of Florida.

>>11568524
>and why would 3d printing organs be any easier in orbit?
Because you don't need to worry about building some degradable scaffolding around it to keep it from collapsing before it is finished being printed.
The scaffolding is the biggest thing holding back the field right now.

>>11568556
Hahahaha if this is true maybe sometime in the medical field should've paid attention in physics

>>11568546
Scratch some of that, we're going to need closer to double Sea Dragon's thrust to get 1000 tons to orbit, diameter will probably have to be changed to 25-28m with 80 engines. If you can build some smaller landing pads you could emulate falcon heavy with multiple Saturn V sized strapon flyback boosters, but with 6-8 of them more like Energia.

>The spacecraft’s internal clock appears to have become unsynced with the mission plan, and so the Starliner failed to autonomously fire its engines at the correct time to drive it toward the space station. The vehicle was cut off from ground communication at the time thanks to nearby satellites, so it missed a backup transmission of the command.

>Because Starliner failed to use its rocket motors at the precise moment and continued on its path, it lacked the propellant to raise itself to the altitude of the ISS, and missed its only opportunity to demonstrate that it could safely reach the orbital outpost. That is the nature—indeed, the point—of a test flight, and engineers at Boeing and the US space agency will use the opportunity to learn more about the vehicle before they put people onboard.

Person who actually tried sending a frog into space here, I don't understand this notion that all I did it for was shits and giggles. Trying to be good at rocketry is one of those incredibly addicting but expensive pursuits that almost no one has unlimited funds or time for. The satisfaction of shots like this one are worth the time and money spent to me, but only if I have some stake in a good outcome. A live animal is about as good as it gets for making you want to invest effort into getting it right.
This isn't the 4chan oldspace program where teenagers on /b/ tied balloons to a frog.

>>11568638
IIRC the nozzle will be sealed by the ballast, so there would be no water in the combustion chamber.

>>11568703
Don't let them concern troll you. The space frog program must go on.

How many Sea Dragons would it take to match SpaceX's full production Starship cadence in terms of tons to orbit per month? Is it even possible to catch up without reusable boosters at this point?

>>11568749

don't be fooled by Musk's overeager estimates. The real number will be much smaller.

>>11568749
>How many Sea Dragons would it take to match SpaceX's full production Starship cadence in terms of tons to orbit per month?
Depends on how fast Sea Dragon can be refurbished. I don't know if there's any estimates of it.

>Is it even possible to catch up without reusable boosters at this point?
I can imagine some kind of SupeR OmegA that has been stripped way down for cost, but that would probably put severe restrictions on what kinds of payloads it could fly.

>>11568703
You've already justified yourself to everybody here who isn't a hyperemotional retard Anon. Every professional space program has also at some point used animals for testing, animals who were probably not exactly ecstatic to be packed into a small dark box and hurled skyward, once the rocket is big enough for a human you find one of those mad lads called "test pilots" who will willingly sit on tens of tons of highly volatile material because I think their bodies must have some mutation which only allows them to achieve orgasm if their blood is pumped full of adrenaline.

For most animals in nature non-consentual, violent death is the norm, nothing about the frog's life or potential rocketry related death will be notably different to it.

>>11568770
This is why people make fun of spaceX fans.

One Sea Dragon per every five Starships, assuming full cargo payloads for both vehicles. It wouldn't match up because SeaDragon in the configuration imagined for it would still require significant refurbishment each flight. A lot less than other contemporary rockets, but it would still need it. You couldn't for example just drag a Seadragon from the water and immediately launch it again, it would need to be returned to shore, cleaned, some smaller parts might have been crushed by it's dummy huge splashdown, the engine will have to be checked over for corrosion due to exposure to salt water, etc.

>>11568791
>Not a real medical term

It’s used in medical literature so it’s a medical term. It’s a synonym for antisocial personality disorder but some draw a distinction.

I like SpaceX as much as the next geek, but that anon has a point. Calling Elon a god is pretty silly.

>>11568786
It's perfectly arguable whether or not most animals are even capable of acting as moral agents which would make them worth consideration, on top of this Anon hasn't killed the frog so this whole discussion is a hypothetical which doesn't belong in this thread. Ethics while valuable and interesting is only tangentially related to spaceflight. It would be more relevant to perhaps a philosophy thread on /lit/ or something similar.

>>11568794
So basically double the margin and two Sea Dragons for every five Starships?

>>11568808
Without modification, that sounds fair. It wouldn't really be fair to compare them though, in the same way it wouldn't be fair to compare Starship and say Falcon Heavy, you'd only ever use a Sea Dragon if you needed either a massive bulk shipment of supplies immediately, or if you needed to launch an enormously large component which couldn't be fit on a Starship.

>>11568815
>you'd only ever use a Sea Dragon if you needed either a massive bulk shipment of supplies immediately, or if you needed to launch an enormously large component which couldn't be fit on a Starship.
I want a future where such launches are routine to lob prefabbed chunks of space colonies into orbit.

>>11568807
>It's perfectly arguable whether or not most animals are even capable of acting as moral agents which would make them worth consideration

Moral agents are beings capable of making their own moral choices. Whether or not a being is itself a moral agent is not per se relevant to anyone else’s moral considerations relevant to said entity.

>>11568818
>making prefab space colonies and not ISRU ones

>>11568822
Gotta bootstrap that ISRU, and there's no substitute for raw volume/mass on that front.

The secret is to only ship in things that you can't make on Mars. You can make

>water
>air
>food
>plastics
>steel
>concrete
>tunnels (the cheapest way to make a shelter)

So with those, you can make 99% of the colony by weight just using materials.

You'd want to use ships to bring in things like plutonium fuel rods, computer chips, different kinds of crops, etc, that you can't make on Mars and that have a high value per kilogram.

>>11568835

Doesn’t matter. Pepe did nothing to you and you should not hurt him

>>11568797
>It’s used in medical literature
Not anymore. Stop reading outdated trash.

>>11568833
True but once in place it can sit around for a while, and if you light up one Sea Dragon and one Starship then you're going to get five times the bang from a single launch. In the end though, fully reusable vehicles will outpace it, if a Sea Dragon sized rocket is designed in the future I'd expect it to have been significantly altered to more closely function like a fully reusable, if it isn't just literally a double-wide Starship copy.

>>11568835
the secret is that shipping the machinery needed to create steel or plastic severely outweighs the initial need for the materials and makes it more economic just to ship supplies in bulk.

>>11568844
>Not anymore.

It’s been used as recently as 2019 according to the first page of a google search.

>>11568835
I don't think you understand fully how much infrastructure is necessary to deliver us things like plastic, steel, and concrete Anon. Those things are super common and easy for us to utilize right now here on Earth only because a hundred years of industry have built a manufacturing foundation that can shit out hundreds of tons of steel, plastic and concrete every day, probably more like tens of thousands of tons.

>>11568846
no it cannot, it cant be on hold the propellan tis not stable.

face it, the idea is shit, the design is shit, its a joke taht went too far

the only vaguely plausible advantage is that if everything goes perfect and ttheres no rpoblem and theres no R&D costs it might be somewhat relatively cheapr over 20 years over regular launcehrs, its worst than them in almost every way.

also, you cant launch ANYTHING thats not blocks of compressed matter because the vibrations will break it. also, its not entierly clear its possible the rockets survives the vibrations

>>11568848
>ship electric arc furnace based foundry, small nuclear reactor, small TBM, small habitat and small plastic factory
>use them to make bigger steel mills, bigger nuclear reactors (just ship the control rods and fuel rods in from earth and use Martian materials for everything else), farms, and a shitload of tunnels

If you're a simp who lacks ambition, you could just send in all the materials, but exponential growth is better than linear growth.

>>11568869
You can if you only load the Kerosine right away, all that shit aside though I proposed >>11568546, so I am fully aware of the potential flaws and drawbacks of the design. I was discussing a scenario in which Starships and Sea Dragons existed contemporaneously with one-another and what their role would be, I thought it was pretty clear that there was an assumption made Sea Dragon would be functional for the sake of discussion.

I think a "real" Sea Dragon would be more like a giant N-1, with a large cluster of first and second stage engines as opposed to pressure fed mega engines.

>>11568872
and what? Have an astronaut shovel dirt into a furnace and get workable metal plates on the other side? I wish real life could be like factorio too, but it isn't.

>>11568857
I don't know enough about plastics to have a strong opinion, but steelmaking isn't that complicated.

>apply heat + CO to remove the oxygen from iron oxide ore to make pig iron
>use either pure oxygen or iron oxide ore to remove excess carbon from pig iron, thus creating steel
>add additive as needed for the grade of steel you want

You could definitely fit a small steel mill onto a starship and then use that to make a much larger ones.

Machine tools can also be built from scratch if you know what you're doing. Gingery made a book series on how to make a complete machine shop from scratch.

>>11568890
>Starships and Sea Dragons existed contemporaneously

>>11568906
>but steelmaking isn't that complicated.
Quality steelmaking is, otherwise you get sloppy chinkshit that implodes.

>>11568906
>iron oxide ore
and where does this come from?

>>11568912
Anon, America industrialized using garbage tier Bessemer process steel with massive nitrogen impurities.

Even shit tier steel is still really strong. And conditions on Mars are good for steelmaking because there's

A: No atmospheric oxygen to rust everything

B: A near vacuum preventing heat from radiating off and massively reducing the amount of energy necessary to keep everything hot.

C: Iron literally everywhere

>>11568906
It's not super complicated until you consider that you might want alloys instead of mild steel, or that for any structural work, even in 1/3G you're going to need a lot of steel if you want to build stable, long lived structures, or that steel also needs forming, welding, and storing. That you need multiple different elements to come together to make worthwhile steel which will need independent mining, refining, and storage as well. Same for copper, same for plastics, plastics are actually slightly worse because you also need robust chemical plants to add various shit to your silica to make it useful.

I'm not against establishing these facilities, but even Starships will probably only be able to accomplish this task (and only at the small industrial town scale) over the course of a decade or two. A colony will need bulk supplies in the meantime, and their ability to scrape resources out of Mars won't compare favorably to Earth's for I'd guess at least a century, probably more because it's harder to do a lot of things in near-vacuum. Unless Starship cadence not only meets but greatly exceeds Elon's estimates, by like an order of magnitude.

>>11568920
mars is 98% composed of iron oxide ore, why do you think is red? its like a dream paraidse for steel makers, with that amount of freely avaivable prime raw ores its theoritised they could make steel twice as hard as diamond, three times lighter than leather and twice as tall as yes

>>11568926
>>11568929
Mars as a forge world for a solar empire when?

>>11568928
I was thinking that you wouldn't use steel for structures.

By far the easiest way to build a structure on Mars is just to have a TBM bore a tunnel.

Steel would be for things like airlocks, industrial robots, rovers, and so on.

You could save like 90% of the shipping weight for a rover or whatever by making the steel parts in situ and just shipping the electronics

>>11567604
You can build an open-air proof-of-concept science demonstrator out of stiff wire, a soup can, and a neon sign transformer. Won't be optimal, but it'd work for a physics class demonstration.

>>11568926
>A: No atmospheric oxygen to rust everything

What’s with all the iron oxide then

>>11568967
As far as I can tell, there used to be an atmosphere, which rusted everything, and then the solar wind peeled it away and all that's left is CO2

>>11568946
You COULD use a TBM, but you'd have to invent a new one that doesn't rely on water and wet lubricant to move the dirt and rock powder out of the machine. As is TBMs drink a huge amount of water to turn rock chunks and dirt into a slurry which gets pumped out of the tunnel. This can't be done on Mars because the normal lubricants and water will rapidly boil off in the near-vacuum. If you try and run a TBM without water you're going to very rapidly end up with a broken TBM.

Easier to use an excavator to dig a giant pit in the shape of your habitat, lay in some steel ribs made up of beams flown in on a Starship or similar superheavy lifter, fill the bottom part with Marscrete, then stretch a para-aramid skin over the ribs to form the ceiling, add airlocks and pressurize the space (once pressurized it will help support more weight) and then lay a shell of marscrete blocks overtop it like an igloo till it's sufficiently shielded from radiation.

Yes, it will require some materials to be shipped in, but in a best case scenario it would probably take a colony a decade at least to develop the infrastructure to manufacture them in-situ even in small amounts, much less the quantities required to construct large habitats.

>>11568929
>twice as tall as yes

>>11568397
Mexican space taco trucks. Imagine.

>>11568976
I've seen Mars habitat designs that just use these boys and hard rock to make tunnels.

You might have to move around until you find something that's geologically stable enough to function without reinforcement (or with positive air pressure as the only reinforcement) but it's way easier than building a habitat from scratch.

>>11568929
>why do you think is red?

I feel like long after we've had manned bases on mars it's still going to be an open secret that mars is tan and blueish gray. Even the sunsets are blue. And in the year 2100 they're still going to be throwing that piss rust filter on every movie about it.

>>11569007
seriously it's almost comical how underpowered it is for SLS

>>11569013
Looks pretty red from the rover pictures

>>11568976
You only need a hole to start the tbm machine in with an airlock over the end. Pressurise as you go, yes without a liner you will probably have a slow leak leak of air into the outside material but it will be very slow and you can keep up with the replacement rate.

Dunno, I don't know enough about drilling to say whether it's plausible or not, it just seems like it would be a simpler operation to build what is essentially a giant steel-ribbed tent, especially since our Mars colonists would need the open space to stop from going absolutely fucking crazy after a few years of living in a box. If you could get a TBM to operate on Mars it could definitely do some impressive work. Low G would help it to move material along faster.

>>11569118
The 70s were a dark time.

>>11569108
wait new glenn can't lift anywhere close to a falcon heavy? Is any of the hype real? Why are they so secretive about a side-grade and all we can see is an overpriced fairing?

>>11569128
Knowing how Jeff works he's probably underselling on purpose so he can brag about "increased rocket production X%" later.

>>11569128
I'm not certain of that figure's accuracy. I've heard 12t TLI, which is less than expendable FH but more than reusable FH.

>>11569117
Makes sense considering Blue's design philosophy and the rocket itself though. Falcon Heavy uses KeroLOX for all three stages which makes it much more compact. New Glenn on the other hand is a MethaLOX first stage and LOX/LH2 second stage, the most mass and volume inefficient type, because I guess they're still somewhat hung up on the LH2 paper numbers meme. It also doesn't dump any of it's weight as it ascends, so that's going to further cut it's efficiency, while Falcon Heavy dumps close to two thirds of it's dry mass when those boosters detach.

>>11569142
>It also doesn't dump any of it's weight as it ascends
They're trying SSTO?

>>11569118
Yeah but you'd be paying for the multi-state jobs program

>>11569142
a hydrolox upper HELPS its capacity to TLI compared to FHE

>>11569145
Nah, it's a TSTO with no side boosters. Falcon Heavy on the other hand has triple a Falcon 9's thrust with no real downsides as it loses the boosters before the core stage burns out so it doesn't have any detriment from having to drag extra dry mass. Honestly I think the biggest problem facing New Glenn and eventually New Armstrong will be that compared to say the Raptor, the BE-4 is extremely anemic in terms of TWR and ISP, because it's a much more conservative design. Raptor is a fundamentally more ambitious engine due to it's higher chamber and turbomachinery pressures and the complexity of it's fuel cycle.
>>11569153
The extra needed volume plus extra mass in insulation to store LH2 exceeds it's added efficiency in bipropellant rocket engines, it's a meme until we start using it in NTPRs.

>>11568637
because there are no living things in the ocean

>>11569167
Didn't the Raptor need some new metallurgy to make internals that wouldn't slag out under full flow? I doubt they're sharing with BO.

>>11569167
>The extra needed volume plus extra mass in insulation to store LH2 exceeds it's added efficiency in bipropellant rocket engines
i don't even know where to start on how wrong that is

>>11569173
Don't recall off the top of my head, that might have been in relation to the turbomachinery blades themselves, same problem with the RD-180, hyperoxic environment, high pressure, and high temperature, necessitated a switch from metals over to carbon-carbon in the RD-180 if I'm not mistaken.

The combustion instability is solvable.

>>11569193
Okay. Look at the slope of the line here. For stuff like LEO swapping out hydrolox is kinda a wash. But when you start going further, it adds up. Even at TLI.
FH expendable can brute force its way past the lesser efficiency of kerolox for most destinations, but it is losing potential performance because of it.

>>11569214
but more engine bad, muh N1

>>11569214
Yeah, doesn't he know it's literally impossible to solve combustion instability in large chambered liquid propellant rocket engines? They'll never build a big rocket engine,

>>11569213
Nixon also signed the NRC which ended nuclear power development in the US

>>11569128
it does not. every one of thoses graphes compares falcon heavys full expandable mode to new glenns reusable mode for some reason. since falcon heavy can only lift about 30tons to leo fully reusable that means new glenn is about 50% stronger than FH

The real villain were these guys:

>>11569224
I see what you mean, I guess my focus is somewhat myopically concentrated on getting off of Earth, since that's the most autistically resource intensive part of any launch. What that makes me wonder though is why New Glenn is using a HydroLOX second stage, it's only functions seem to be space tourism and satellite launches confined to Earth orbit and possibly some GTO's. No mention of more ISP intensive things like probe launching or TLI's at all.
>>11569233
F1 was only complex in terms of components because firstly the technology of the time greatly limited how things could be manufactured and assembled, and secondly because it was (and for now still is) an engine in a size class all of it's own. It didn't have one of the more complicated fuel cycles and concept engines like the F1-B would indicate that it doesn't have to be a nightmare of 50,000 unique hand adjusted parts.

Sometimes I wonder if space flight would be better off if the Space Race never happened. Am I the only one?

>>11569273
100% definitely.

the world would be better without capitalism and the us

>>11569273
It had to happen for even the bare minimum we have now to exist. If it weren't for a fear about the existential threat of commies owning space the country couldn't have been convinced to be invested in spaceflight at all. They'd still be saying ".2% of the budget? But what about GIBSMEDATS, that could buy a whole year's worth of food stamps for people who are perfectly fit in body and mind but refuse to work anyways!!" At least we have a space program, at least we managed to get a few sets of boots on another celestial body, at least many of the early problems of rocketry have been solved already.

>>11569293
This. The instant the Soviets gave up, Congress slashed NASA to the bone and it never recovered.

>>11569293
maybe this is the great filter

>>11569253
What I'm amazed is that it took so long before someone high up in (American) space flight started wondering out loud "why the hell is everything so slow and expensive?"

>>11568862
Helium 3 is useless and not present in concentrations that would allow mining it. To get one ton of helium from regolith you need to process 100 million tons of dust and rock with zero leakage, 100% capture. It is never going to be worth it; it would be less resource intensive to use deuterium fusion engines (which would exist first anyway, if we had the ability to fuse He-3 at all) to fly out to Uranus and harvest He-3 from there to bring back to Earth. It would be still less resource intensive to just use deuterium fusion reactors on Earth for power, especially since the technology to break even with He-3 fusion means you can build D-D fusion reactors with >100:1 fusion energy return on investment by default.

If Spacex didn’t come along nothing would have changed
All the other “new space” are the same as old space
Blue Origin spends a decade developing shit unrelated to an orbital rocket...

>>11569301
They didn't even really give up, their retard economic and social philosophy irreparably fucked up their economy and government structure to the point where by the time Saturn V and N-1 could have been flying together it was already too late for them to have a chance at the Moon. That's the real difference between our two space programs, the Soviet program could no longer go on because socialism fucked up their entire country, the US made a deliberate choice to duck out of serious space work after the Soviets self-destructed.

I'm not sure which is more depressing, failing miserably or just quitting due to disinterest.

>>11569371
Hydrogen isn't ideal for sea level launches but it's still workable and can be cracked from water along with oxygen, plus there are processes which can create methane or kerosene, propane, ethane, etc. If fossil fuels do begin to run low other superior energy production methods will take up the load of power grids as they should have decades ago, and with cheap energy a lot of other currently energy excessive processes become more viable.

>>11569371

Ok, I'm going to take a shot at this with a bullshit analogy

The apollo program was evel knieval. People hold positive attitudes towards motor bikes, but they tuned into evel knieval because a guy was going to make a record breaking jump more daring than the last and potentially die, that's as far as they gave a shit. You should not be confused why they inevitably returned to caring about their own lives until the next circus. You shouldn't wonder if motor cross would be better off and have a more stable following if it wasn't for evel knieval. It has nothing to do with it. Space is just normal background noise to people like aviation, automobiles, whatever. You have fans but unless something unusually impressive is happening you're not captivating the nation. People weren't "burned out" on space because of apollo was too much hype. We just found out what the normal state of attention was after it was over.

And I admit bullshit analogy because the pricetag of apollo definitely had political consequences.

>>11569344
subcooled propane and liquid oxygen achieve one of the very best densities among rocket propellants with ISP better than kerelox

>>11569320
>especially since the technology to break even with He-3 fusion means you can build D-D fusion reactors with >100:1 fusion energy return on investment by default.
While you're right, if (when?) deuterium or tritium fusion becomes commercially viable it will eventually produce enough helium to make some kind of helium fusion viable as well.

>>11569343

hmmm, how about the two ships covering the image with "SIZE MATTERS" slapped in the middle? that would give it a better look, and maybe changing the background to something to accentuate them

>>11569658

>>11569659
This is great, legible and the contrast of colors can stand out.

>offeror

I know english can do better

>>11569678
How did ULA lose when there’s no evidence they actually took part? Boeing’s not a medium & heavy lift launch vehicle provider either, so Elon wasn’t referring to them.

>>11569678
If SNC is contracted, ULA will still get launches out of them.

>>11569673
Ok elon is 'absolutely booty blasted lmao' or whatever, what is your point?

Lengthening the rockets and changing the background would be abit of a pain to do, but I did the Elon Xi and text change. I changed the font and color to make it stick out more.

>>11569727
And a non-text one in case you just wanted that.

>>11569723
He has a perfectly valid reason for using a trip. He's trying to organize something and doesn't want some other anon pretending to be him.

>>11569727
That works, it's great.

>>11569723
I personally do not like to use a tripcode, but it's just to organize this like this anon said >>11569730 , after this i'm back to anon.

no the raptors are in the background, that's the Boca Chica build site

Today on Starship tweets
>SN4 won’t get flaps, so can only do flights with engine on. Just did a reset this week on flap, actuator & static aero design. Either SN5 or SN6 will get flaps.

Nope, we can make degradable scaffolding out the ass. There are number of huge problems with bioprinting. One is that it's difficult to make structures with sufficient resolution to make blood vessels. Another is making the right type of scaffolding. Putting in the right biomarkers at the microscale so cells will go in the correct places and align in the correct direction. We certainly can't make extracellular matrices that are as good as decellurized organs. We can't print continuous collagen structures. Dumb fanboy.
