the astronomers are gonna be so pissed. imagine a starlink train of 400 sats!

>>12298827
Oh hey, confirmation of expendable deep space yeet SS.
>Massive delta velocity slam from highly elliptical Earth orbit using a fully retanked, but lightened up Starship with no heat shield or fins/legs. Best choice for the impatient. Ion engines are too slow.
>Probably no fairing either & just 3 Raptor Vacuum engines. Mass ratio of ~30 (1200 tons full, 40 tons empty) with Isp of 380. Then drop a few dozen modified Starlink satellites from empty engine bays with ~1600 Isp, MR 2. Spread out, see what’s there. Not impossible.
I could've sworn it needs all its engines to make orbit, guess not.

>>12298528
Orion is like throwing sticks of dynamite behind your rowboat when you can build a jetski

>>12298497
Modern chinese are infamous for being shit at metallurgy.
They can copy stuff all they want but if they can't get the quality right it will never work.

>>12298852
>it's so simple, just take the most complex path
Anything like this we tried to build today would be a .00000001 T/W power hog and shit itself immediately. Orion is practical and could've been done yesterday, it just needs to be constructed far from (((Earth))))

>>12298852
We could have had humans at every planet in the solar system with project by 1990, and humans on their way to another star system by 2000 if the project wasn't banned by anti-nuclear shills

>>12298528
What's the Delta V of a nuclear bomb powered spaceship?

>>12298887
How could have Orion been improved over the years?

>>12298887
Science knows best.
Technology is bad.
All capitalism is bad (besides yoke corporations).
Your leaders care for you.

>>12298891
It ranges from "full solar system interplanetary trade" to "from earth to proxima in a few years". Depends on the quality of nukes. 50's tended towards the former, assuming institutional knowledge degeneration in the field did not occur and computers can help us surpass the 50's nukes, we should be tending toward the latter.

>>12298891
10,000 to 1,000,000

>>12298898
The Orion design typically seen is based on existing tech at the time, you could probably cut a shitton of dry weight with improved dampers and a more efficient delivery system. I don't know about the core mechanism but there's probably been improvements in nukes too, right?

>>12298655
I lol'd

>>12298914
That's ISP though.

>>12298908
I'm not sure there's enough uranium around to make this possible
on the other hand, deuterium can be easily sourced from space
conveniently, cometary water is naturally heavier and electrolytical enrichment would generate plenty of LH2/LO2 bipropellant as side product (or vice versa, biprop refinery would generate deuterium as byproduct)

Why did they make the James Webb telescope as that huge starwars imperial destroyer-like thing instead of making it as several smaller modules that can be shipped on several trips and assemble themselves together in space. It would have been trivial to do it this way. It's almost as if a woman came up with the idea.

>>12298827
putting satellites in the thrust section seems like an expensive way to dispose of your satellites.

Also, it's inside the fairing? i see a escape system, but it does not look like it's attached to the pod but to the fairing.

>>12299003
Imagine the smell!

>>12298944
There is plenty of uranium, the limiting factor is enrichment. The answer is the right decision regardless: use fusion bombs. They can get away with depleted uranium as the main source, which is dirt cheap by comparison, we chuck the shit at hajis.

>>12299030
So inspired by dragon2 but cramped and 10x shittier? I love it. Poo in LEO is the only based statespace there is.

>>12298989
Dated and held back orbital telescope progress to the point ground telescopes surpassed them. NASA still has mirrors gifted from the airforce that are vastly superior to the hubble ones just rotting in some forsaken storehouse because they don't need them - gotta wait for the jwst.
It's like observatory started in the late 1800's and taking a century to build - but also preventing other observatories from being built that are better in the meantime.

>>12299030
They're gonna send up this robot in the "uncrewed" flights

Calm down anon. Green Run will happen in early November 2020. There's no need to be upset when its months away from the December 2020 hot fire date.

Halted nuclear development has far more to do with lobbyists from coal gas and oil companies than it does some random irrelevant treehuggers

>>12299047
Never, raptor is a shit engine and the reason why SN8 will never make it to 15km. It just ain't robust enough to survive much more than 30 seconds of thrust. Eating its melted innards is commonplace now, and shutdown is marred by the 600hz mode. Raptor is simply not up to the task SN8 purportedly is meant for. Maybe in a couple years SpaceX will solve the issues, or go bankrupt trying

>>12299049
Thank God for Trump! #Trump2020

>>12299051
When they fly in 2022, where will they go?? Does India have any plans for a space station?

>>12299063
fossil fuel corps were the funding, treehuggers were the useful idiots and PR division. Corps couldn't just come out and say "nuclear will eat into our monopoly". They needed to put a smiling face behind the move, and libs gladly played their part. Good intentions etc etc etc

And soviet sympathizers seeking western disarmament for noble reasons. Literally the same breed of marxist pieces of shit causing trouble today.

>>12299063
And the nuclear industry itself which stifled the development of more scalable solutions. Nuke development has become untenable due to the cost and time investment, we should've been working on small breeder reactors for the last 50 years instead.

>>12299060
Same pattern with solar/wind. Locally there was gigantic push by the green retards for clean eco friendly wind power.
After achieving their goal and building shitloads of those noisy expensive things now they want them dismantled because literally birds. As far as I know solar parks have trouble with lizards in some places.
It's like following the will of a schizophrenic - it can't possibly end well.

Solar parks also zap birbs, I think usually by blinding them permanently with reflected sunlight. I mean, imagine having giant super sensitive eyes five times more powerful than a human's and you're flying along doing whatever the fuck birbs do (what even is a bird?) and suddenly you're staring directly into the sun being reflected from dozens up to hundreds of mirrors.
Greentards are literally mentally defficient and don't understand that any time humans majorly change an environment animals are also going to have their lives disrupted, whether it's by smog or reflected sunlight or a bunch of huge spinning blades.

>>12299122
Why not just tie a bunch of birbs to a string and when they fly they pull on a turbine?

>>12299098
>>12299122
>muh burds
You chucklefucks are just as bad as antinukers, neck yourselves. Cats and windows kill more birds than the power system of the entire nation running on wind or solar would by orders of magnitude. This is just equal and opposite SJW nonsense.

Have these niggers ever heard of evolution? We are simply breeding smarter birds with hardy eyes and heat resistence.

Fuck off greenie, your grid solutions are just radically inferior to nuclear in every conceivable metric that's important, accept it.

>>12299139
I love birds. What's that got to do with what I said? What does seething about something that has no effect on bird populations help birds? If you want to help birds you should be screaming about neutering pets instead.

Assuming I have a way of continuously injecting ethanol and air into the chamber, would this generate any significant thrust?

>>12299141
why do space agencies make these stupid humanoid robots? are they used to test cosmetics?

>>12299142
Sneed nigger, I never said one bad word about nukes. Wind, solar, AND nuclear are all part of the future of energy.

>>12299092
it feels like the last 40 or so years has seen stagnation across the board. Space, nuclear, theoretical physics, and so on. As soon as the boomers got their hands a system it went straight to shit. We're finally getting some gen x leaders like Elon who are pushing back, but some of these institutions have been boomer'd straight into the ground and probably can't recover. At least not for a long while.

>>12299098
it is deeply ironic that solar and wind have turned out to have big problems butchering wildlife. But from the start they were never a good idea because they take up enormous amounts of space which == massive habitat loss. It's far better to have a small nuclear facility in the middle of a forest than to destroy the forest habitat for a "renewable" energy source that kills everything flying near it. Not to mention waste from used-up batteries, solar panels, and so on.

I feel that these people believe that because they mean well that whatever they do will work out. That's obviously fucking wrong. The laws that govern reality only care what you do, not what you think/feel. If you give the "wrong answer" to a problem it's going to blow up in your face regardless of intent.

Oh, but making use of unused space with solar is a great idea. Solar tiles? Sign me up. Takes care of most of the downsides of a massive dedicated farm

>>12299049
Good. That shit shouldn't be NASA's job.

>>12299126
the entire point of wind/solar is that they're "good for the environment". Otherwise there are too many downsides to put up with them.

>>12299154
That image is horrific, I'm contacting my representative now. This bird genocide MUST end. Fuck

Is Russia ever going to succeed at going to the moon? The N1 failed because Glushko refused to help Korolev, Energia was designed as a moon rocket and was one of the greatest rockets ever but fell apart almost immediately due to retarded politics, hell, even the Proton could probably be used for a moon mission if 4-5 of them were launched in quick succession.

Remember to stay hydrated, /sfg/!

>>12299154
>more muh burds
No.
>>12299157
The point of wind and solar is that they're cheap and fast. If the nuke industry hadn't been cucked by the enriched uranium meme, the same would be true of nuclear, but instead it takes billions and decades to put up a nuke powerplant today. It's just not possible to build it out at competitive speeds until the industry embraces small breeder reactors.

>>12299173
Im coomin, im coomin, im coomin, im coomin

>>12299166
Isn't russia involved in artemis in some way?

>>12299166
The Proton is being retired because of its nasty hypergolics and its relatively low launch success rate. If the Russians got their shit together and actually launched the Angara A5 more often, then that could be used.

>>12299183
I think with the Lunar gateway, but seeing as how long it's taken NASA just to build the SLS I have doubts that it will actually happen.

>>12299183
They were gonna make a docking port but we're not sure they have the industrial base for that

>>12299150
Depending on the vessel, and amount of ethanol, either nothing or just blow up

>NASA makes announcements about "alien life" every 3 months

With New Glenn and Starship on the horizon, F9 and FH eating it's launches, and new threats from the russians about a reusable launcher to launch in 2100, what's the purpose of Ariane 6?

so euros can continue to spite Americans by refusing to launch on anything but European rockets

>>12299209

>>12299214
>>12299216
>stopgap
With all the problems they have getting Ariane 6 of the ground does their next generation launcher have any chance of coming to fruition?

>>12299221
So long as they can suckle from the EU's teat then they're safe

>>12299195
>What does the ESA do?
Issue delays, beg for more money, and most of all bitch about SpaceX

Would NASA be more successful if they were just given enough money to build their own rockets in-house instead of contracting out to Cuckheed and Bungleing for everything?

>>12299238
No

>>12299231
Cant they just get subsidies from the EU? Or is giving gibs to Poland sucking up all the funding?

>>12299245
yup

>>12299238
They would end up contacting out to those oldspace companies anyways because NASA management likes them.

>>12299217
Ariane 6 keeps getting pushed back further and further and the ruskis are in just as bad shape. What happens when they have nothing but A5s against Starship, or even Vulcan/NG? Come groveling or lose all pretense of control over the european launch market seem like the only options.

Then their point is moot right? They are like "Of course they will achieve those things! They are being subsidized by the government and NASA! Otherwise their model wouldn't work!" And yet they themselves rely on subsidies to exist.
It hurts my brain the extents to which these people try (and fail) to justify themselves. We are talking about adult, intelligent and accomplished people arguing like children. The only possible explanation is complete corruption if you ask me.

>>12299238
Even when NASA had infinite funds in the 60s they were contracting the work out of Aerospace manufacturers, they were just less scummish about completing projects on time

>>12299351
A rare species of bird has inhabited the foam of the SLS core on the test stand at Stennis. It's called Mimus shelbyglottos.

Will the green run test fire the SRBs and the RS25s?

>>12299360
Wait a minute, how the fuck are launch escape systems in general not pendulum rockets? Wouldn't they flip the capsule upside down?

>>12299370
Nope, they're gonna test them separately, then attach it all together for Artemis 1 and hope it works :^)

>>12299375
Oh no puller bros, we got too cocky

>>12299375
Pendulum rockets can be just as stable as "regular" rockets. They're just not inherently stable, and thus require other means of stabilization like any other rocket.

>>12299385
Oh gotcha. I've heard they stuff it with depleted uranium or something like that. It must be for stability

>>12299385
Any rocket that isnt inherently stable is a failure. RCS is for pussies. Reaction wheels is for pussies.

>>12299396
I guess that capsule with a corkscrew of solids on the bottom I made to start KSP career mode is the only good rocket ever made

oh no no, other two months delay for ULA

>>12299427
It was cold outside, she's nice and toasty in there

>>12299238
They have enough money, Falcon 9 development cost what, 10-12BN in total? What they don't have is the right team, the right facilities, the right tools, etc. NASA is optimized to manage the assembly and launch of rockets, not the manufacture and development of rockets, which is why they have always historically contracted with American industrial companies to do that end.

oldspace has completely ruined peoples' idea of what aerospace costs should be

Have we actually seen what SuperHeavy’s new landing legs will look like? They look so dumb in everyone’s mockups

>>12299453
Yeah I think I was thinking of something else, high estimates call it 390 million actually, probably not much higher than 500 total from gen-1 Falcon 9 to the Full Thrust version flying now. So NASA actually has more like 40x the amount of money strictly *necessary* to develop say, a 20-25 ton medium lifter. Assuming an anual budget of 20BN.

>>12299471
Falcon 9 but bigger.

>>12299471
Do we even know what Starship's legs are supposed to look like? Surely those crushable stumps they've been flying on the prototypes aren't close to the final version.

>>12299471
SS is getting new legs, is SH confirmed for a change?
Also gotta wait for the new starship update, although at this rate it might just show up on the pad first

>>12299377
sounds like a fucking stupid idea

>>12299448
>>12299453
>>12299467
There was a nasa study about potentially making their own F9 in the traditional way. It turned out to be around 10-15B, actually. The initial draft's pricetag was damning was not very acceptable, however, and an updated figure, using more realistically optimistic estimates was made, concluding they could possibly if everything goes perfect do it for about 3-4B.

Wish I saved it.

>>12299461
Ah it was linked from the mockup and I didn't think to check the date, I just assumed it was recent.

>>12299448
>Falcon 9 development cost what, 10-12BN in total?

>In 2011, SpaceX estimated that Falcon 9 v1.0 development costs were on the order of US$300 million

>A 2011 NASA report "estimated that it would have cost the agency about US$4 billion to develop a rocket like the Falcon 9 booster based upon NASA's traditional contracting processes" while "a more commercial development" approach might have allowed the agency to pay only US$1.7 billion".

Yes, and they confirmed it in a 2017 report: https://ntrs.nasa.gov/citations/20170008895

>Just for context, the commercial cargo program’s up-front development cost to NASA was a total amount over 6 years equal to about what NASA would have spent in 10 months on the ever-present Space Shuttle “upgrade” developments

>The most significant improvement, beyond even the improvements of 2-3Xtimes reviewed to here, was in the development of the Falcon 9 launch system, with an estimated improvement at least 4X to perhaps 10X times over traditional cost-plus contracting estimates, about $400 million vs. $4 billion.

>>12299360
I miss the swoosh decals on the SRBs.

>>12299535
Ironically, that's exactly what ESA did with Ariane 6.

Guys I just had a dream where starship flew with superheavy for the first time. superheavy didn't stick the landing and blewed up, but starship made it to orbit successfully. it also happened to be on US election night, and I was trying to convince everyone that starship getting to orbit was way more important than the election by a long shot.

They gave SpaceX chumpchange and saw returns on their investment they never could have dreamed of and their takeaway was "sending a few hundred million to SpaceX for project development is a good idea" instead of "supporting newspace is more cost effective than spending billions plugging literal holes in our oldspace endeavors"

>>12299577
Alright Elon we get it

>>12299577
A bill passing that prohibits the use of methane (greenhouse gas) as rocket fuel and your starship is DOA.
Even if you don't care about politics, a time might come that politics cares for you.

>>12299427
Damn it I wanted a distraction from the election tomorrow

>>12299594
It was just dream logic anon, i'm not that autistic irl. I also was somehow playing a simulated version of the rocket launch in which i accidentally made the rocket spiral out of control and crash, and I somehow got my hands on a starship model which was completely irrelevant to the rest of the dream.

>>12299594
>A bill passing that prohibits the use of methane (greenhouse gas) as rocket fuel
Then switch to Ethane.

>>12299594
Literally nobody is proposing this

that's a lot of fucking Starlink

>>12299603
Why does Starship use methane instead of heavy hydrocarbons like Falcon 9? Is it really just because of the in-situ fuel production meme?

>>12299594
This already happened. Elon has been breaking the law for YEARS. He will be stopped

>>12299616
Elon had a slide about this, comparing kerosene, hydrogen and methane

>ISRU: hydrogen and methane easy, kerosene lol good luck
>fuel transfer: methane and kerosene easy, hydrogen gay
>density: kerosene very good, methane good, hydrogen gay
>efficiency: kerosene mediocre, methane okay, hydrogen magic unicorn farts

>>12299616
It's not because "muh mars", it's because if you want to fly Starship thrice a day methane is the cheapest fuel. Easier to store, handle, cleaner through the turbopumps. It's just cheaper all around.

>>12299616
ISRU is part of it, but also specific impulse. Having an energy dense fuel like kerosene is great for getting to LEO, but specific impulse matters much more when traversing around the Solar system. That's why hydrogen is commonly used for upper stages. Methane gives a balance between hydrogen's efficiency and kerosene's density while still being common and relatively easy to handle.

>>12299195
launch one unmanned rocket every three months

>>12299603
Wow I can’t believe hydrogen is the standard fuel when it’s so gimped for density

>>12299616
>more efficient, easier to wring that efficiency out of (no weird unpredictable byproducts to account for in the reaction), doesn't slowly freeze with a common tank wall and LOX, doesn't soot up your reusable engines

>>12299631
Different anon but how hard would methane be to produce on Mars? Where does the Hydrogen come from? Also good luck trying it on the Moon, I don't think there is any Carbon to work with. Not trying to be a naysayer- just interested to see if it will actually work

>>12299427
Was this supposed to launch in August?

>>12298475
https://www.whitehouse.gov/wp-content/uploads/2020/10/OTMP-Florida-Report.pdf?

Leftists salty on Twitter over this report from Trump WH

>>12299645
Why?

>>12299639
It's actually WORSE than it looks, because LOX is nice and dense, most fuels have some sensible ratio between 2:1 and 1:1 for LOX, whereas hydrogen needs something like 4:1 hydrogen to LOX so you lose EVEN MORE density relative to other fuel combos

>>12299643
Dig for coal and bring hydrogen in the form of sulfuric acid from earth. Break down the sulfuric acid into h2o which is then electrolyzed and poof you've got hydrogen + carbon = methane.

>>12299643
Water comes from ice, carbon comes from the Martian atmosphere which is almost pure carbon dioxide. CO2 + H2 -> CH4 + O2

>>12299639
It was a revolutionary breakthrough for upper stages. Even von Braun didn't think it was possible, but it allowed the Saturn V to carry a larger payload to the moon than what a purely kerolox rocket could do. Compare the Saturn V's TLI payload of 48.6t to the N1's 23.5t. Without hydrogen, NASA would've had to build a Nova rocket for the same mission.

>>12299643
>Where does the hydrogen come from?
Anywhere that isn't the equator
>good luck trying it on the Moon
The Moon is an afterthought for SS. Elon had a clear design goal in mind and said "fuck Urf and fuck the Urf system". In theory they could cart carbon there but a Moon rocket should have a different cycle based on plentiful elements which is why I will always shill aluminum hybrid lunar boosters showering the moon in glorious sapphire dust.

>>12299631
It's temperature is also close to lox so you don't experience trouble with common bulkheads due to temperature differentials. Kerosene is prone to freezing, hydrogen to boiling. Since you lug lox anyway having your other propellant behave similarly as far as temperature goes is good.

>>12299647
Orange man bad, did you expect a nuanced critique of the President's economic plan for Florida or whatever?

>>12299658
Yes

>>12299655
Oxygen only ISRU and BYOCH4 works fine on Luna, as you said it's not the main goal. There's a reason SpaceX declared Mars independent but declared the Moon to be California.

>whereas hydrogen needs something like 4:1 hydrogen to LOX
Yeah, but you run fuel rich, so blend ratio is actually in the ballpark of 6:1 which is the "optimal" for the RS-25/RS-68. Real life might be even more fuel rich than that.

>>12299900
Either way, my point was that hydrogen runs so fuel rich that you don't get hardly any benefit from the density of LOX, compared to fuels that run at more sensible ratios. Which doubles down on how terrible hydrogen's density is.

Arcjet-NTR hybrid rocket when?

>>12299934
Kerolox does not run 1:1 for that matter. Absolutely optimum ratio is 2.56:1, but good luck hitting that.

If I time traveled back to 1950 and told von Braun that 21st century rockets run on methane, would he have switched to it?

>>12299946

China produces a lot of steel yes, not quality steel.
All the steelplants in the west survive even with the chinese market underbidding them massively because the western steel plants always deliver the steel with the required qualities.
And western steel plants can make some "exotic" steel variants that the chinese market cant even hope to replicate, even with stolen tech.

>>12300209
China seems to be focusing in increase their skill in material science with the whole made in china 2025 stuff, so they know that they should bridge the gap as soon as possible.
Presumably they could made their steel up to eastern yurop average today if they invest in quality control, but it is hard to know what they will prioritize there.

>>12300256
Not him but I think it fundamentally goes against Chinese culture to make high quality space age shit. The only thing those bugs are truly good at is mobilizing, everything else is pure shit compared to the west in nearly every way.

>>12300256
Every advancement of CCP china so far has been by stealing tech from others.
And the west has realized this, and is taking action.
I would not be surprised if this catchup project hits a wall.
And i now about the "made in china" movement they have, it is already failing, even with the chinese being massively nationalistic they still buy non chinese products.
The baby milkpowder situation for example in china is so fucked up that chinese are buying up that stuff from all over the world instead.
All of this is down to the fact that chinese society has haggling&scamming&cheating as being normal.
Chinese people dont feel guilt as long as they aren't caught, and a lot of people in the west don't seem to understand this fundamental difference with western cultures.

Haggling is normal everywhere, but the scamming and cheating is the issue. Still, Xi could fixed that by aggressively cracking down, albeit that relies on political will which he may or may not have.

Still, I think China will catch up, especially since everything they are being accused of doing have also been leveraged against Japan, Soviet Union and even the USA.

>>12300354
>Still, I think China will catch up
I dont, CCP china is on borrowed time.
The western nations know the CCP is responsible for corona, and when the west has dealt with their corona outbreaks they will be back with a vengeance.
And CCP china only can sustain itself in peace time with the military boots pressed against the throats of the people, if those boots are gone to fight some foreign enemy the whole carthouse collapses.
Balkanized china in our lifetime, 2020 shitshow is only the start.

I have some bad news, I think the HDLT anon overstated the efficiency of the engine. It might be another VASIMR dead end.

>Power is required only for the maintenance of plasma and the creation of the magnetic field. In our current bench top prototype, 250W is sufficient to create several milli-Newtons of thrust.
This is closer to 0.01N/kW than 0.1N/kW.
>In space the solenoids that generate the 250 Gauss of magnetic field this requires we estimate could be cooled to 200K, reducing the resistance in the coils by a factor of 5 and representing a power consumption of a few 10s of Watts.
The 200K magnets are the 0.1N/kW ballpark. Looks like 1N/kW would require superconductors.
>Relative to other existing systems this constitutes quite a power saving and is well with-in the capabilities of solar panels. The 0.5sccm of feed gas represents a mass consumption of 160 mg/hr, so that a typical 5 hour burn would use 0.8g of propellant.
This part is still super based though.

>>12300354
While I have no doubt China is capable of 'catching up' in some ways, it isn't some universal inexorable truth. This is the space thread and right now the CCP is hopelessly behind in aerospace. At the same time, their biggest historical advantage of simple resource and manpower control increasingly falls by the wayside as their alienation forces more consoomers to look inward and become producers. The most hopeful thing they have going for them right now is running a debt scheme on the third world.

>>12300423
ISP calculations for HDLT are weird because they look like shit if you use the electric rocket equation instead of actual mass flow. For that 250W thruster mass flow is something like:

0.00016kg/hr / 3600s/hr = 4.444444444444445e-08 kg/s

Of course that creates less than 10mN. If we assume Ve stays constant for larger mass flow thrusters (and it should) then we multiply by 100 and chop some sigfigs to get 4.444x10^-6 kg/s for a 1N thruster. IIRC that means 4.444x10^6m/s Ve, which is 4444km/s, which is pretty fucking great.

If you use the 0.01N/kW value and plug it into the electric rocket equation (which is meant for electrostatics like ion drive) you probably get that bad ISP value.

>>12300460
Didn't they also test it on a super small proof-of-concept thingee? I remember them having trouble measuring it at all because they had to insert shit into the plasma to measure it directly, which disrupted the plasma iteself. IIRC they talked about upscaling it and changing the design to make it have more thrust (but ESA was doing all the testing so they either cancelled it or they aren't going to get around to it for another twenty years)

They seem to have a semi-comprehensible plan for the future, at least in the short term.
Honestly I don't understand why you seem so hellbent in the idea that the chinks will never catch up no matter what.

>>12300694
Stop believing everything you read from chink newssources.
If they were to be believed, they're going to build electric hall thruster planes shortly.

>>12300697
>electric hall thruster planes
For where, Mars? Those flat out won't work on Earth.

>>12300701
No shit.

I am quoting https://www.theregister.com/2020/11/02/huawei_in_house_chipmaking/#:~:text=According%20to%20the%20Financial%20Times,of%202020%2C%20the%20FT%20claimed, which seems to be accurate.

>>12300705
And where the fuck do you think they sourced that news?

>>12300706
>And where the fuck do you think they sourced that news?
Huawei, but I don't see why it would be impossible to catch up, especially with a 22nm by 2022 roadmap.

Chip fabrication general. Every time.

>>12300715
What? First time I've seen it. I blame CCP dude who just kept spamming 'muh silicon' in lieu of a salient argument.

>>12300722
He's joking because usually it's right/left politics cluttering the thread, not a highly granular discussion on Chinese chip-making lol
Keep going though, this is interesting to me

I bet NASA will announce SLS will require another $2 billion just for a green run tomorrow. Also the maiden launch has been slipped to 2022. They'll think no one will notice

>>12300731
In hindsight I shoulda said
>Silicon fabrication general
to keep it /sfg/

>>12300738
Is NASA announcing something?

>>12300738
The green run is tomorrow?

>>12300738
They're doing a green run?

>>12300738
What's a green run?

>>12300738
Green beans?

>>12300738
>They'll think no one will notice
Tbh they'll be right about that, most normalfags don't really care about space unless it's something big like the SpaceX Crew Demo-02 mission or something.

good thing we don't have a democracy. we have a republic.

hmmm

Very reddit and very cool

Republics don’t last forever. Every nation, every culture, every religion, every ideology, every ethnicity, and every city will be ground to dust by the wheel of time and replaced by something new, forever and ever

>>12300825
bad thing we've slowly been giving voting rights to every social group imagineable and who would of guessed it turned out to be a bad fucking idea. we should of remained an aristocratic republic the 1790s.

The earliest cities of man are dusty ruins in the desert, and the same will be true of the city you inhabit eventually.

>A continuous nuclear explosion while engine is under power
Is that the steam exploding due to heating from nuclear salts, or is that a nuclear explosion from the salts going critical?

>>12300874
they were weaker men

>>12300880
You are weaker than a badass Sumerian king, warrior, or peasant.

15 km flight when?

>>12300888
Never, raptors are shit and can't last more than 5 second before eating themselves

Never. I ate all the Raptors

Yes.

>>12300878
both

We made it to Mars bros! Just- don't go outside for a few years...

i wonder if the retard will come

>>12300947
Which one? Piss airlock? Prooonter? Shelby? We have a whole Starship's worth of them.

>>12300950
nationalize this man

Why are solar panels so inefficient and gay? If you doubled their kg/kW you could do so many cool solar electric designs, all the way out to Mars. Imagine this fucker with twice the thrust and the same mass of panels.

electromagnetic spaceplane launch when?

>>12300950
>>12300958
should i tell you?

>>12300970
Solar panels do work great all the way out to Mars though

Why would someone write that? And why would you let more people know about such a thing?

how does ventilation work on spacecraft? will i have to smell everyone's farts for 6 months on my way to mars? where do the farts go?

>>12301072
>how does ventilation work on spacecraft?
you can scrub the co2, but you can never scrub the shame
>will i have to smell everyone's farts for 6 months on my way to mars?
yes

>>12301072
>where do the farts go
activated charcoal and baking soda
>will I have to smell everyone's farts for 6 months
no
>how does ventilation work on spacecraft
fans and ducts

imagine the amount of semen in starship when it arrives at mars

>>12300867
I doubt it means anything, and they're just calling it that because it's dead weight, and probably not a very heavy weight at that. Perhaps there'll be a Photon/kick stage test associated with it that'll be revealed later.

work is being done on them. Beware though, as nuclear propulsion concepts get more fleshed out their performance tends to decrease...

THORIUM BABY

>>12301225
don't work for nuclear saltwater torches
thorium might (I'm not an expert) be good for nuclear thermal or for breeding U-233 to power your nuclear salt water rocket
either way, reacting thorium is a slow process

>>12301215
I'm very split on the prospect of an american civil war.
On one hand it'll probably ruin america cultural hegemony over the west so I won't have to deal with america racial politics in movies/shows/books/comics anymore.
On the other hand, starship is being built in texas.

>>12299876

Good. The right needs to be put in their place at least once per century so they know who the boss is.

Says a lot about the Shuttle that Russia had nearly a decade of exclusive transportation, and yet only a third as many cosmonauts have been to the ISS compared to American astronauts.

>>12301272
>Says a lot about the Shuttle
Yeah, that it had seven seats on it, duh. Dragon has as many seats if they ever want to scale up that much again.

why the fuck does malaysia get to go but not poland? racism?

I used to clap for Chinese human spaceflight program (yay more humans in space), but now I hope that their progress is slow.

If they ever land on the moon, they're gonna claim it as their territory like how they claim everything on Urf.
