And is SLS not a part of Artemis? Thanks for mentioning that too—they kept Gateway alive. A toll booth grift designed to “chain” Congress to the Moon… and we know how that works out long-term (see: MSR samples being left on Mars. Turns out adding cost and complexity doesn’t save you money)

I know i'm going to get a lot of shit for this, but russia won ever battle, US won the war in the space race.
And i still dont understand how the US went from going to the moon to riding bitch on the soyuz to the ISS.

>>16135064
Simple. Rockwell lied like a used car saleswoman with a law degree about the capabilities and price of their STS bid (which is why they no longer exist) and then NASA had to apportion shuttle contracts so carefully between Congressional districts that fixing the flaws after Challenger was impossible.

If Korolev didn't die would the Soviets have landed on the Moon? Assuming that Apollo goes on the same as IRL, and N1 flies in the 70s. Would there still have been enough will on either side to continue?

>>16135081
Who knows, there are some who claim that the N1 was actually becoming a lot more reliable when they pulled the plug on it.
Others say it was a shitshow and that it ever got of the ground is miracle.

>>16135064
The United States was sabotaged from within, otherwise there'd have been Apollo-derived Mars and Venus missions by the mid 80s.

Someone should do an alt-history like SENPAI but without all the gays and lame drama.

Soviets cut their losses because it was embarassing having their superheavy rocket explode every time when the American one worked flawlessly. If N1 worked, or even if Saturn V exploded a few times then I think Soviets would have done it.

>russia won ever(y) battle
isn't even remotely close to true. the r7 was head and shoulders above any american launcher from 1957-1964 but the soviets were still failing to get a lot of firsts due to their deficient electronics - especially with how mariner 2 and 4 were the first probes to return any useful info from venus and mars. voskhod was a desperate stunt to try to paper over how gemini was ready years ahead of soyuz. after voskhod 2 americans spent nearly 2000 man-hours in orbit before a soviet flew again... and that flight was soyuz 1.
>>16135081
what would korolev not dying have fixed? the n1 was the rocket he designed, and mishin was his right-hand man who korolev trusted more than any other. what we got irl is pretty much what we would have gotten in an alternate timeline. the n1 would have still been a disaster and korolev would have ended his career in disgrace. dying young was a good move for him, since it let him become a totem for lazy alternate histories rather than a subject for critical historical analysis.

If N1 worked and the Soviets had not quit the space race would have continued and there would be Moon colonies already.

>>16135129
aerospikes arethe most holariousl stupid design ever

>>16135114
Korolev was the dominant political force in the Soviet space program. It would have recieved more resources, suffered less infighting and not been cancelled before what might would have been its first successful flight.

>>16135142
Sober up before you shitpost.

>>16135129
>>16135142
have any aerospike engines been flown yet?

>>16135156
Yes, many, but nobody wants to fund bigger projects.
Not since the whole X-33 shitshow.

>>16135131
What about turbopumps? What's the limiting factor for making them fit inside a liter?

So common we don't even hoot and holler and hop around like apes anymore.

>>16135144
i could buy that line of thinking if korolev hadn't been one of the primary sources of infighting himself. was he a dominant political force? no, he couldn't get development of the n1 authorized until 1964 largely because he'd discredited himself with lots of the power players in soviet politics. even after 1964 the project suffered for lack of resources because korolev and chelomei were fighting over control of the manned flyby program.
note that i'm not claiming this is all korolev's fault. but it's a matter of fact. the whole n1-l3 project was never in good shape. it was always years behind apollo. even in a best-case scenario they wouldn't have been ready for a manned landing before 1972 - and that would've just highlighted how much less capable a soviet lunar mission was than a j-class apollo landing.
you can come up with alternate histories where the soviets get their act together years earlier and come up with a rocket design that isn't held together with hopium - it's not impossible that the space race could've continued. but korolev alone isn't your ticket to that, and in fact i'm not sure he helps at all.

rainbow dash looking ass

>>16135219
nice, i'm still kind of mad about the whole x-33 situation, the launch pad was ready, the x-33 test version was 90% done.
Congress pulled the plug because of the composite tank bullshit while the alu tanks turned out lighter and more reliable.
The us army wanted to step in and fund to al least see it fly one time and find out of aerospikes actually work so they could claim the entire project.
Congress blocked that too.
So two options, aerospikes actually work and it would destroy oldspace, or it was a massive scam and they killed the project at the last second so nobody could find out.

>>16135224
Given how buttmad Tory Bruno still is about cancellation I'm pretty sure it would have worked. Ironically the Venture Star would have been happening right around the same time as Falcon 9 so we could have seen an aerospike shootle with optional flyback kerolox LRBs for heavier payloads or higher orbits.

>>16135243
what do you "worked" the vehicle they had would never have made orbit
If there was any weight bloat on the final vehicle which was not under construction then your payload disappears

The N1 test flights are a lot like Starship test flights, except there's not a lot of definitive proof that the Soviets ever fixed any of the issues the explosions pointed out. Switching to the next generation engines was a good move, and it was in line with the original projections of the rocket being ready for service sometime in the mid-seventies.

oh no no no

>>16135808
Nuh-uh. It's not obsolete. It's just on track to become obsolete in the near future.

And from a procurement perspective, an inferior design isn't obsolete until there are at least two competing providers of the superior design (and whose designs are operational and proven). Ideally, more than two.

>>16135808
As Thunderfoot said, the ONLY reason to have loads of small engines isntead of one big engine is that you dont have the expertise to build a big one.

>>16135816
They looked into massive engines before (Sea Dragon) and deemed it too unreliable ie. it might work but has a good chance of blowing up every now and then

>>16135816
There's no need to develop the expertise to build a few big engines, if it's cheaper to develop the expertise to build reliable plumbing for 33 small engines, and cheaper to produce more units of a single type of engine rather than fewer units of two types of engines

>>16135818
>a good chance of blowing up every now and then
we have been cruelly denied kino

the only complaint i have about raptor is it doesn't need to be that complex (FFSC) because of the relatively short burn time ie. like S-IC; yes the specific impulse is better but they could've just gone with a standard staged combustion and simplified it a lot

>>16135827
*relatively short burn time of the Super Heavy because it stages fairly slow and low (same principle as F9) to allow for reuse

>>16135827
Doesn't FFSC help with reusability?
Doesn't it put less strain on the turbopump(s) for the same performance, and alleviates the issue of interpropellant seals?

>>16135818
Would that be as much of a problem today? They didn't have the same simulation capabilities back in the 1960s

>>16135827
Yes but counterpoint: by slaving away and making the best rocket engine ever made (which evidently is only going to get even better) they end up mogging others in both thrust AND efficiency—not to mention the cost is lower than any other rocket engine of similar caliber save for maybe BE-4 (I only say that because Blue Origin provides a small engine price, but they could be fudging numbers)

How are they still alive?

>>16135310
>the two major theoretical possibilities were [a] antimatter and [b] primordial black holes.
Antimatter is just an extreme version of preexisting energy storage methods. Fuels can already explode and be difficult to create. There's nothing strictly stopping us from using antimatter as fuel already. The only problem is being able to use it at great scales. I'd say figuring out a way to create antimatter more efficiently is much more plausible than figuring out a way to create a black hole.
Though I will admit, having black hole production lines and shipping them around to be used up does sound cool as hell.

The drum is spun backwards to deposit the material. I wonder if they will dump it into an enclosed augger, as I don't think you want conveyors to move material.

It will be interesting, maybe they will use a binder and extrude the material to consolidate and keep it together, then process it.

>>16135837
scraped through selling the engines they got buy buying another company previously, but even that would be in better state if they didn't fuck with it (like half left/got fired of that department)
chris kemp is probably quite charismatic, but very shit at executing or technically in general

>>16135885
why wouldn't you want conveyors?

>>16135875
As in, based purely on the technical nature of the engine design itself

>>16135888
For the same reason they wouldn't use conventional buckets on the excavator. The movement that the conveyor imparts is going to result in a shower of dust. You want to keep the regolith enclosed and using rotation to impart momentum that keeps the material against the enclosing surface is a means to do that.

>>16135891
I don't think you can separate them
designing for mass manufacturability affects the performance and cost itself
cost is cost

>>16135897
no, youre an idiot.

>>16135887
Kemp was visibly tweaking around the office more than once and used to work at NASA so I think it's a mix of drugs and oldspace rotting his brain. I don't know what the fuck Adam London ever did. A big part of the delay for Rocket 4 is they licensed engine designs rather than just buying off the shelf parts so they tried to force march their engine manufacturing teams to advance about ten years in two, while cutting hardware engineers and almost their entire software department from launch ops to datalake to flight software down to the bone instead of ejecting all the email job foids. This worked about as well as you would expect.

>>16135898
so we can't compare the cost of a mass manufactured car with some hand built supercar?
of course we can, don't be ridiculous

>>16135914
>>16135898
to make this point clearer
when you decide to choose a bigger vs smaller engine, one of the factors is how many engines you build
the smaller engines will get greater economies of scale, so that will be a benefit in choosing them for instance
you can't just look at this in vacuum

>>16135917
Except for upper stage engines, those need to be looked at in a vacuum.

>>16135116
That's right. We don't tolerate it. We encourage and propound it.

>>16135897
If we don't separate them, engine design becomes conflated with industry structure. SpaceX has labor, money and market share that would allow them to benefit from economies of scale even if they had chosen a different engine design

Is China preparing a SAR megaconstellation?
Ku band, 230kg, stackable flat panel

>Taijing 4-03 satellite is a high-resolution flat-panel SAR imaging satellite developed by Micro-Nano Starry Sky. It is my country's first commercial Ku-band phased array radar imaging satellite. The satellite weighs 230 kilograms, has a resolution of sub-meter level, and has multiple imaging modes such as bunching, striping, and scanning. The observation width in sliding mode can reach more than 10km. In addition, Micro-Nano Star Sky has designed and implemented a flat-panel satellite configuration for the first time. This configuration mode can realize multi-satellite stack launch, laying the foundation for large-scale satellite network launch, and its commercial technology level is at the leading level in the world. The satellite adopts an on-board intelligent processing system that can quickly generate images in orbit. For the field of ocean monitoring, it can quickly detect and identify sea and airport targets.

>Multiple sources have confirmed that NASA is studying alternatives to the planned Artemis III landing of two astronauts on the Moon, nominally scheduled for September 2026, due to concerns about hardware readiness and mission complexity.
>Under one of the options, astronauts would launch into low-Earth orbit inside an Orion spacecraft and rendezvous there with a Starship vehicle, separately launched by SpaceX. During this mission, similar to Apollo 9, a precursor to the Apollo 11 lunar landing, the crew would validate the ability of Orion and Starship to dock and test habitability inside Starship. The crew would then return to Earth. In another option NASA is considering, a crew would launch in Orion and fly to a small space station near the Moon, the Lunar Gateway, and then return to Earth.

IMAGINE using SLS for this, forcing the lunar landing to 2+ years away instead of finding a way to launch Orion seperately like on Superheavy autonomously, god fucking damn

>>16136004
Artemis IV will be dock to Gateway, HLS dock to Gateway and first lunar landing, and return to Gateway, I knew it

So Artemis III might not even go to the Moon at all lmfao

>>16136015
>IMAGINE using SLS for this, forcing the lunar landing to 2+ years away
What if it was going to happen 2+ years away anyway?

>>16136004
lmao, an SLS launch just for Orion to dock with Starship
Polaris is already doing that with Dragon and the launches cost like 200mil on those instead of 4bil or whatever the fuck SLS + Orion launches cost

>Now that production of the Delta rockets has ceased, it is not clear whether more of these interim stages could be produced—at least not at a reasonable cost.
at a more reasonable cost than the EUS, sure. if you're really worried that you can't make another IUS before 2028 then the right thing to do would be to cancel artemis 2, since that's a publicity stunt mission that doesn't advance us toward a landing in any meaningful way.

>>16136004
Changing the mission this late in the game doesnt speed up timelines or reduce complexity

>>16136012
Surprisingly no, but I know one that could...

>>16136004
>The Starship-Orion mission has another benefit that sets it apart from a Lunar Gateway mission: It can be done without a powerful upper stage on the SLS rocket. For its first three Artemis missions, NASA is using an "interim" upper stage for the Space Launch System rocket based on the Delta rocket and manufactured by United Launch Alliance. Now that production of the Delta rockets has ceased, it is not clear whether more of these interim stages could be produced—at least not at a reasonable cost.

So this alternate Artemis 3 would use an SLS without an upper stage since it is only going to LEO and the 2 remaining ICPS are needed for Artemis 2 and the first landing.

Falcon Heavy cannot lift more total mass than a Falcon 9 due to the structural limits of the second stage.

Rather than making Falcon 9 a super heavy lift rocket Falcon Heavy makes it a 'high energy' heavy lift rocket, which is why you don't see it used very often.

>>16136080
>nasa's just throwing a fit because they weren't as good at computer modeling as they thought. heat shield erosion was well within acceptable ranges.
My thoughts exactly, they're letting their perfectionist autism get in the way of good enough, Apollo never had this problem because they didn't have that kind of modeling back then

Seriously more needs to be said about this model autism, rn in F1 Mercedes are struggling to match real world performance with their precious models too

How can it be harder to hone T/W if the "same" engine is improved with greater thrust? Is the engine being made more than 70% heavier to achieve 70% more thrust, or what?

>>16136155
it's not the same engine. increasing engine thrust lately has involved adding mass to the engine. cant say much more

>>16136155
they open the throat to acheive a greater flow rate so the expansion ratio is lower and the isp goes down

>>16136150
Yeah thats the sense I got, they're willing to delay Artemis II just to perfectly align their models, its frustrating

why does hubble orbit nice and snug close to earth whilst jwst has a massively elongated and eccentric orbit like kepler?

>>16136147

>>16136190
unironically "just be yourself"

>>16136173
Probably not in the spirit of things if you're only considering chemical propellants but NSWR could be a good Lawful Evil candidate. Alternatively you could go with pentaborane or one of the fluorine mixes

https://twitter.com/elonmusk/status/1781188584084582905

>>16136172
That means Orion will be replaced with Crew Dragon

>>16136190

>>16136173
flip the vertical axis. it makes no sense that denser things are eviler.
also put fluorine/lithium/hydrogen triprop as lawful good

>>16136218
Saves money on not needing expensive EUS, giving more time to test out heatshields for Orion, and more time for Starship to perfect landings, budget friendly, etc.

Its a "win" move in terms of de-risking a lot of things

>>16136221
denser = evil just because I think of toxic hydrazine and SRBs as the "evil" way of doing it vs the "good" hydrolox, methalox etc. just a personal preference. also light = angelic, heavy = devilish.

>>16136239
Helium (cold gas thruster)?

>>16136001
Probably closer to Starlink V1s. That said though, if China goes all in on flatpak designs. It's going to seriously change how satellites are made world wide.

>>16136201
alright.

>>16136221

>>16136173

>>16136247
>>16136257
>>16136261
aaaand its finished. cold gas Helium does indeed have tiny density and laughable ISP. you could fit a couple in each box but Im limited to one each
>>16136255
it incidentally lines up with that, hydrazine being toxic, SRBs being difficult to handle/likely to blow up (Challenger)

>>16136266
>low isp, high density: earth, mercury
>high isp, low density: gas giants
>high isp, medium density: icy moons

>>16136004
They should go with option 1. It's vastly more useful politically and public sentiment wise to have orion dock with HLS in orbit and give the entire world a live stream of a crew of 7 people living in a spacious space penthouse with futuristic design and minimalist aesthetic with an onboard water and plant deck with huge windows looking out at the Earth below.

What NASA and US aerospace thereby desperately needs is a big PR win that affirms why all the spending and man power has been worth it. You can then use option 1's wins to justify option 2. It's easier to convince the public to build a new space station around the moon if they all get a real view of the possibility of being able to afford a trip on a space hotel in their lifetime. It's infinitely harder to justify a new space station around the moon when you ask for $100Bn, talk 30 year timelines, and make the glamour and glory of space still a pipe dream for everyone but governments and the uber wealthy.

You can still have orion and SLS Block B and Gateway and everything else, but only as long as make sure option 1 happens first. Because the added benefit of option 1 is that the HLS Starship remains parked in low earth orbit pretty much indefinitely and it can be used as a station which Axiom and Polaris and other commercial crew missions can dock onto and use the space as a hab for experiments and manufacturing testing and other missions.

Can go as far as selling HLS in parking orbit in LEO as an Gateway precursor, where everything that would need to integrate with HLS can be tested in low earth orbit. Then the cost of putting up parts and validating integration, fuel transfers, power transfer and system upgrades, all can happen more rapidly and at 1/10th the cost for 2x the return on science and useful manufacturing data--ensuring Gateway to the Moon is the best version of the system it can be.

Rocket Lab really needs to get a move on with their engine program

>>16136536
They're not entirely following America here. China created the "Strategic Support Force" as a separate branch already back in 2015. It was supposed to handle space, cyberspace and intelligence. I think it was a bit similar to the US Space Force, NRO, NSA and military intelligence rolled into one. I think it was thought that there was a lot of synergy, and it kinda makes sense. However they have apparently now decided that the Strategic Support Force will be broken up into three components.

China's Aerospace Force still isn't a perfect analogue to the US Space Force. China doesn't distinguish between a Space Force and Space Command. China only has combatant commands for the 军. At least I think that's the case.

It's probably because space is about to become such a big thing, that it's now considered to deserve its own distinct branch.

Still no turbopump on that engine. Been doing these tests for a year.
Relativity is dicking around equally.
Only Firefly and Stoke seem to be doing well.

lmao im a retard

>>16136537
Both 军 and 部队 can be translated as "force", "service", "service branch", etc. The official English translation is a bit weird, hence why I used the Chinese characters. 军事 also means related to military matters in general.

The official translation of 军 is "Service" and the official translation of 部队 is "Arm". However, the official translation of 空军 is Air Force, and the official translation of 军事航天部队 is Aerospace Force.

China not welcome here, git out

>>16136554
I think rocket lab is kind of fucked on the launch side, maybe their satellite bus business will stay alive though

>>16136564
tick tock Peter Beck.

>>16136563
it's good to keep an eye on them

>>16136521
aerospace force doesnt sound like a space force at all. they probably handle alot of satellites, but do they handle space launches? anti satellite weapons? why is aero included in with space? do they do high altitude stuff too like the spy balloons?

>>16136554
Is Rocket Lab falling into the same pit that Blue Origin spent years in?

can we all pour one out for Bryan Malinowski as well?

for example, russia's aerospace forces include ballistic missile defense alongside their military space units

>>16136569
you need to understand that the Chinese air force isn't functional like the USAF

>>16136535
Sounds more like Air Force that also does space. They don't even have a separate air force so far, or a separate navy. It's all part of the army

>>16136569
Most of China's spaceports - Xichang, Taiyuan, Wenchang and Jiuquan - are run by the PLASSF, so the new Aerospace Force will likely take over that responsibility.

> why is aero included in with space?
"Aerospace" is a common translation of 航天, however it really means spaceflight, as far as I know. 航空 is aviation.

Reminder about the chinese guy who was posting about the liquid electric pump fed engine he made and hotfired and then suddenly died while he was working on a GG cycle one

>>16136564
I've always said that the small launch companies that will come the closest to prospering are the ones with a very effective side gig. Rocket Lab is probably the best positioned out of all of them.

>>16136570
Building bigger engines, especially staged combustion designs, is hard. It doesn't have to be a painful, decade long process, but you have to take it seriously and budget your resources accordingly.

>>16136594
we had a couple of people making engines in 2018 and they all died lol

>>16136581
They most certainly have a separate air force and navy that is distinct from the army
>>16136521

Your confusion might stem from over-interpreting the translation "People's Liberation Army". It could just as well have been translated as "People's Liberation Military", however for historical reasons People's Liberation Army is the official translation. Historically, the PLA only had a ground component, so it didn't make any difference. However, nowadays, because the US and UK use the word "Army" to mean ground forces exclusively, that causes a lot of confusion.

All of these eight forces are part of the People's Liberation Army

>>16136599
Things like "People's Liberation Army Air Force" or "People's Liberation Army Navy" always felt like retarded translation errors made by someone who was being a bit too literal.

>>16136599
>>16136601
Strictly speaking, the word army is not exclusive to ground forces. The word "army" comes from French "armée", which in turn comes from Latin "armata", which means an armed force. Ironically, the word "army" has the same etymological origin as the word "armada".

France's Air and Space Force is called Armée de l'air et de l'espace in French

I believe the word "army" has come to refer exclusively to ground forces in English as other forces grew out of the ground force and became distinct enough to deserve their own name

>>16136601
the united states had an army air force before 1947

>>16136601
It's not even being literal. It's about adding accidental meaning during translation that didn't exist in the original word. In the Chinese name 人民解放军, the 军 refers to military in general, with no "ground" connotation. Ground force is 陆军, navy is 海军, air force is 空军.

We should argue about their meaning in Danish. That way we can have a truly inclusive discussion in which everyone can take part.
