Your fundamental assumption is that combining the world's nation's existing talent pools would multiply the amount of space happenings several times over.
In reality, most space-related engineering talent has already either migrated to the USA, or was generated in the USA via SpaceX.
Forcing SpaceX to work with ISRO, the chinese, ESA, and so forth, would only bog down SpaceX. Even giving SpaceX infinite money would hardly increase their rate of development, since right now they are mostly throttled by regulatory bodies, not absolute physical ability to build and launch prototypes.
If you want more, and better, space technology development, the solution is not to all hold hands and sing, and it's not to scoop more GDP percentage out to direct towards launching more rockets, it's to reduce regulatory hurdles and startup costs so that people who are already interested in doing these things will be more likely to take the risk and try to do those things.
Also, at the moment the market kinda sucks for any new players to try to jump into because every niche has a well established and competitive player already. Things will ramp up and get a lot more exciting a lot faster once Starship is operational and we are doing human things on the Moon regularly.

Theoretically.
I mean Depp did it against Amber Heard and her ACLU lawyers.
But some would say that was just because she’s crazy and melted down in front of the jury.
Jessie Ventura did it against Chris Kyle.
But Kyle got shot in the middle of the trial by a ptsd vet who he was with on the range.
They all had expensive lawyers but I’m sure musk could afford some as well.

To win, you have to prove malicious intent.
Which usually is hard, but might easier to prove in this world of cameras, messages, and internet toxicity.
It could be a turning point where people realize that defamation/libel is easier to prove with modern technology now.

>>14698009

Thats why they get away with all sorts of fake news. Tabloids have existed since forever.

>>14698121
I'm more surprised that reputable news journos are doing the whole tabloid attack against Musk. Going the whole rumors/personal attack story against him.

So uh, how exactly are we going to mine asteroids when they are so loosely bound that poking them causes a huge plume of debris to fly out everywhere? Can we put them inside a large bag somehow?

It's going to be highly restrictive if we only have the ability to excavate resources from asteroids spinning fast enough that they can only be monolithic objects, though.

>>14698167
>poking them causes a huge plume of debris to fly out everywhere?
This is not really an issue.
>Can we put them inside a large bag somehow?
That's a great option if you plan on consuming the entirety of the asteroid.

Sure there's many ways.

There will be no room for JPL faggotry where we're going.

>>14698213
>That's a great option if you plan on consuming the entirety of the asteroid.
This should always be the goal, resources is resources and everything has a use. You're in microgravity anyway so there's no reason to be worrying about mass so much.

>>14698245
One day you'll be right but due to the nature of Earth launch the first vehicles to begin mining asteroids are going to have been built with a fair degree of mass autism, this is inevitable. It's the asteroid colony civilization itself which will invent the super-robust spacecraft needed to shrug off constant dust and pebble showers.

4chan is back

>>14698256
Starship or something very much like it combined with containerization and orbital cargo transfer stations will be the key if asteroid mining involves downmass to planetary surfaces, which it must at first - orbital refineries are juuuust a bit harder than reusable launch vehicles.

What are the resource limits for fusion reactors?
Ultimately the energy source of the future will be SBSP and/or fusion reactors, just wondering what the downsides to fusion reactors are. Afaik they use a decent amount of rare earth metals for the magnets/capacitors ect and they use up some space and a lot of water for cooling.

I think there will be a brief boom of ground solar in the next couple decades as the panels get very cheap, but then they will fairly quickly run out of places to put them.
People won't want solar panels everywhere.

Orbital refineries are easy. Step one, build a rotating ring spacecraft. Step two, mount molten oxide electrolysis cells and material conveyor belts to the inside of the ring. Step three, install high temperature radiators and solar panels to the outside of the ring. Operate the MOE cells, you are now refining rocks into highly pure metals and oxygen.

UR-700 is cool, but seeing as the much simpler proton was exploding left and right, I highly doubt it would have worked.
The USSR should’ve just picked either the N1 or the UR-700 back in 1963 when the US said they’d go to the moon. The N1 started work in 1965 and flew first in 1969. They could’ve had it flying two years earlier if they actually gave a shit.

lmao you think so?? It was a frankenrocket of the highest degree, it obviously would have never worked.
That being said, the real timeline-shifting decision would have been for the designers of N1 to insist on using a cylindrical first stage that had the same diameter as the second stage, thus allowing it to be transported by rail, thus allowing for ground test firing of the stage, thus preventing the embarrassing launch failures which ultimately canned the design.

>>14698713
>thus allowing it to be transported by rail
It's physically impossible to move something the size of the N1 stages around by rail in the USSR. The largest rocket segment that could be moved around by rail in the Soviet Union were 4.2x25m, which is why the proton has a single huge oxidizer tank on the first stage with separate fuel tank modules for each first stage engine that got bolted on once the parts arrived at Baikonur. If you're going with rail transport you'd have to use a cluster of 4m modules like the UR-700 instead of the N1.

>>14698852
Helium 3 fusion looks retarded once you understand that due to physics, fusing deuterium with deuterium is orders of magnitude easier than fusing helium 3 with anything. Yes, D-D fusion makes neutrons. That's also simply not a problem. The economics of using a fusion reactor and dealing with neutrons is FAR superior to the economics of mining and processing a gorillion tons of lunar regolith for every ton of fusion fuel. Also, let's not forget that we would need thousands of tons of fusion fuel to power the whole planet no matter what fuel we use, so at minimum we would need to be mining and processing tens of trillions of tons of material on the Moon then launching thousands of tons of helium 3 back to Earth, and that's assuming the whole Moon industry is both 100% efficient at capturing helium 3 and also is powered by solar or something that doesn't involve fusing helium 3.
It's the dumbest idea for making a lunar economy work. It is unironically less feasible than a 100% tourism-based lunar economy.

>>14698862
The N1 second stage was transportable by rail. Even if they needed to make the first stage such that it could be separated into two tank sections and a thrust plate section for transport, it would have been better than the real life solution of "disassemble the stage completely and rebuild it at the launch site".

>>14698975
Tritium is the best (easiest) fusion fuel though, so really by letting it decay you'd only be making a shittier fusion economy. Sure, your conversion efficiency MAY be a bit better if we can figure out direct energy conversion of fast protons generated by helium 3 fusion, but it won't ever be enough to offset the efficiency losses due to much stronger plasma energy leakage mechanisms at those much higher temperatures necessary for helium3 fusion.

A D-T reactor can breed enough tritium from lithium to sustain itself over time.
A D-D reactor needs higher temperatures but can run forever on just deuterium, and if you breed some tritium from deuterium surrounding the reactor you both recapture a lot of that lost neutron energy and you aren't burning up valuable lithium anymore, while also boosting the reactivity of your reactor. A triple win.
A D-He3 reactor still makes some neutrons (because D-D side reactions are much easier than D-He3 reactions) but it's not enough to breed enough tritium to let that tritium decay to sustain the reactor's He3 burn rate. It wouldn't be enough even if you were using a lithium blanket to make your tritium. Breeding He3 is only something you'd do if you had an application that absolutely required He3, like an interstellar probe that needed to use aneutronic He3-He3 fusion at barely breakeven power levels but the highest available Isp fusion propulsion. That engine would be shit as a power reactor, barely keeping itself self sustaining using the same tech that would give you very good D-D fusion engines and outright D-T torch drives, but for piddling away at 250,000 Isp for one hundred years at TWR close to an electric ion engine, it'd be fine.

>>14699092
I'm not sure how much faith I'd be willing to place in the confidence of soviet engineers, but they'd at least be less complexly disaster prone as the first stage.

Clustering up seven 4 meter cores would get you a block 12 meters across that you could comfortably fit the second stage on top of it. The real question is which engines you could use in it. You could (barely) fit 2 NK-15/33s into the tail of each module, but 14 of those only gives you half the thrust of the N1 first stage. Seven RD-270s can match the Block A's thrust but then you need to actually get a 6 MN full flow stage combustion hypergolic engine to play nice.

The real benefit of a common core architecture is being able to build Angara 1.2 and Angara 5 on the same assembly line, so what else would a N1 cluster core be used for? You might be able to use an RD-270 core to replace the first stage on the Proton, but the same engineers that were confident in the N1's upper stage reliability were also thinking about deleting the first stage, calling the remainder the N-11, and then using THAT to replace the Proton, so there might not be an obvious other job for a N1 cluster module.

Still, it couldn't do worse than what they actually tried.

It'd be 17m at the base of the last flare. It was just over 10 at the bottom of the second stage, and I'm assuming that if we're clustering things they're going to be more cylindrical than conical. Otherwise we're going to end up with some seriously weird looking modules.

No, China is legitimately communist, Xi is just a fucking autist. Short form explanation is that the communists know that there's a big ??? in the transition from a capitalist mode of production to abolishing the state and living in some kind of communist worker run utopia. China explicitly has what are essentially capitalist DMZs where capitalists can work for profit, but the party HATES them. That's the big problem with Jack Ma, he's hugely popular and antithetical to the ideals of the party. They can't outright destroy him though, because they're the ones who gave him authority to do business, and China needs their business. The entirety of China's policy only makes sense through the lense of communism though, just in a really backwards especially retarded way.

You could read more about this if you want to, but I wouldn't recommend it, it's all really really really dumb. Also, Xi has memorized the entirety of Faust.

How about you ask Roskomnadzor why?

Another possibility. Hear me out. The N1F upgrade was slated for 1974 and it used NK-33 engines which COULD be tested before flight.
What if the USSR skipped the “block I” N1 and instead used a pair of smaller, say 50-60 ton to LEO rockets to launch their initial one man lunar landings until the N1F became operational in 1974? Thoughts?
I did some math and a five core vehicle with 30 RD-107’s could’ve lifted 60 tons to LEO. A pair of these rockets would be able to fly the L3 lunar complex with ease, and they use smaller cores, and most of all, they use proven engines which could be tested on the ground.
It’s not a permanent solution, but one that could do a few one man LK landings until the bigger L3M lander came to

The original N1 design was pretty much the same as the one flown, but it used “only” 24 engines in the first stage, which eliminated the complex plumbing needed for the inner cluster of six, and it also disregarded the supercooling of the propellants. It could still do 75 tons to LEO.
Funny enough, the upgraded N1F variant was designed to fly in pairs for the L3M Soviet lunar base planned for the mid 70’s. So the USSR thought it was a decent enough plan, although the L3M was huge

It's both sad and funny to think that a 100 bucks of sparkers could have prevented the boom under B7

No the 50 ton to LEO thing is true. The earliest design shown on astronautix is the 75 ton variant though.

>The heavy rocket would be developed in two phases:
>N-I, with a 40 to 50 metric ton payload, to be developed as quickly as possible in 1960 to 1963
>N-II, with a 60 to 80 metric ton payload, using nuclear second and upper stages, to be developed in 1964 to 1965

^ From Korolev. So the N-I was 50 tons to LEO, and the N-II was 80.

> N-I: (Korolev) - to be developed in 1960 - 1962. 40 to 50 metric tons payload to low earth orbit and 10 to 20 metric tons to Mars. Draft project to be completed by second quarter 1961.
>N-II - (Korolev) - to be completed in 1963 - 1967. 60 to 80 metric ton payload to low earth orbit and 20 to 40 metric tons to Mars. Draft project to be completed in 1962.

We don’t have any idea what the pre-1962 N-I design looked like. The N-I 1962 design with the 24 engines is the earliest RECORDED one. But it’s technically not

What about the rest of 4chan?

They’re almost finished with them

Sneed it or keep it?

FWIW the annular eclipse six months earlier has a track that intersects the totality track.

>>14699597
>passes through Monroe county, NY
any Penfield anons reporting in?

Fair question since it's a bit counterintuitive that the Moon could block the Sun in polar regions despite it's inclination never varying more than about 5 degree with respect to the elliptic but it's important to note that Earth has an axial tilt of 23.5 degrees and it's very far from the sun, which is enough for their relative angles to cause a polar eclipse. At least that's what makes sense to me.

>>14699597
>passing over the UP
Neat, I'll be looking up

>>14699817
honestly not bad aside from the pants being weirdly shaped

>>14699597
If only it were a few hundred miles SE it would pass over Boca Chica and we could have a launch during a total eclipse.

Oh my God. Did this guy watch or perhaps even make the Project Golden Dragon video?

>>14699597
Why eclipses always happen above North America?

>>14699776
what else is blocked out of curiosity

>>14699996
It's a large continent from the polar ice cap all the way down to the tropics.

>>14700013
Eurasia is bigger.

>>14700016
and also gets a bunch of eclipses

>>14700016
injun witches stole the eclipses from the russian and mongolian witches so they could hog them for all the magic rituals

The hypothesis of the liquid structure of the terrestrial nucleus is deeply flawed, for a reason which science has never been able to confute: Because this liquid mass would be subject, like the ocean, to the lunar attraction, and therefore twice every day there would be internal tides, which, upheaving the terrestrial crust, would cause periodical earthquakes!

Yet it is evident that the surface of the globe has been subject to the action of fire, and it is quite reasonable that you might suppose that the external crust cooled down first, whilst the heat took refuge down to the center.

This is quite a mistake. The earth has been heated by combustion on its surface, that is all. Its surface was composed of a great number of metals, such as potassium and sodium, which have the peculiar property of igniting at the mere contact with air and water; these metals kindled when the atmospheric vapors fell in rain upon the soil; and by and by, when the waters penetrated into the fissures of the crust of the earth, they broke out into fresh combustion with explosions and eruptions. Such was the cause of the numerous volcanoes at the origin of the earth.

They're distributed pretty evenly, as part of the 18 year long Saros cycle.

When does this one happen?

>>14700063
Somewhere within 1,262 years. The period is at the bottom of (>>14700055).

>>14700055
are those the only ones that ever happen or are there any "off cycle" eclipses

>>14700025
The liquid outer core was not assumed, it was the result of seismology measurements. Any alternative model of the Earth would have to quantitatively match that data, otherwise it's just noise.

Secondly claiming volcanoes come from surface combustion is retarded and cannot work. If you have heat coming from the outside then the highest temperature will be at the surface. That is basic thermodynamics, if heat is flowing down then the temperature gradient is positive with the highest temperature at the outside. We don't have temperature to liquify rock on the surface, so it's wrong.

Perhaps consider basic physics first next time.

Based horsefucker :)

>>14700182
wtf based

>eutelsat and oneweb have agreed to merge companies
oh shit it actually happened

>>14700206
wikipedia is out of date but eutelsat has dozens of commsats in geo. i guess they'll transition their existing customers from the slow geosats to the oneweb sats?

>The retard uses arduino for electronics. That's middle-school tier bullshit.
Invalid opinion detected.
His flight software is low quality shite and that has nothing to do with running on arduino.

>>14700219
his flight software is good enough
he is the first person in history to land a solid rocket

>>14700234
it is good enough yeah. i'll watch his video when it comes out

Could HTP and ethanol make a good non-coking, non-cryogenic fuel combo for a low budget re-usable liquid engine?

HTP is obviously very dangerous, but HTP kerosene works and LOX ethanol works so why wouldn't HTP ethanol?

>>14700283
brainlet here
can't you just run HTP as a monoprop?

no bully Phobos, its a useful moon

>>14700283
I'm a dumbass, this is the fuel mix for the German rocket planes, so yes it is suitable for a reusable rocket engine.
