>>16149908
The fact that the LM-12 has such perfect overlap in capabilities with the LM-8A was a bit confusing until I realized they're built by different groups (SAST and CALT) who are probably chasing the same LEO constellation market. LM-12 should be cheaper to fly since it doesn't have boosters or a hydrogen upper stage, but CALT said they were setting up to produce 50 8As per year so they might be able to brute force their way past that with economies of scale. It'll be interesting to see how this shakes out, at least before rockets like the Tianlong-3 and Zhuque-3 come along and make all of these expendable vehicles irrelevant.

This is just embarrassing

>>16149995

>>16150010
Is this the new "but the fairing isn't big enough" cope to throw some pity bucks at ULA

The most mass launched in a year by a single country was 500 tons.

10 Starships launching 200 tons 5 times a day would be 20 times that much in one day and 4 million tons per year.

>>16150007
no, that chart is only for orbital launches, starship isn't on it.

>>16149957
I don't think the relative cost matters that much. I think both LM-8A and LM-12 are meant to be the "conservative track" for launching China's megaconstellations - designs that are as cost-effective for GW/G60 launch as possible without being so ambitious that they are at risk of encountering delays - as part of a wider hedging strategy at the national level. LM-8A and LM-12 being CALT's and SAST's respective contributions to that purpose. Neither of these rockets are likely to have a long career, because they will be made obsolete by reusability within a few years.

I think the relative production rate of LM-8A and LM-12 will be based on whatever workshare is needed to fill up their respective factories, not based on their relative cost.

CALT should already have a lot of 3.35m and 2.25m production equipment from the hypergolics that are being phased out. WSLC already has a underutilized pad able to launch LM-7/8. It makes sense to use this for LM-8A. SAST builds LM-6, 6A, 6C and LM-5 boosters, so they can repurpose their 3.35m equipment to those.

>>16150010
Is it due to structural issues, because it uses parts that were originally designed for the F9?

We've already got one schizo insisting that the moon isn't real. We don't need competing delusions. Russia's made threats in the past about shooting down GPS birds with their own ground based ASAT systems, but it's dubious that they be able to hit a target two-thirds of the way to geostationary orbit. Russia also does not have any co-orbiting payloads at that altitude. If they did it'd be all over space twitter. Those autistic astronomers are about to independently track when Russia moves its assets around in geostationary orbit to snoop on other peoples' hareware. You can't have secret hidden satellites.

>>16150531
5 tons?

Youtube comments buried on TF latest vid, seems legit desu

>You're gonna love this juicy insight coming from industry people, mostly on NASA side. Musk's 40-50 tons is embellished, actual metric is 35 tons or less. The reason why performance is so far off in reality compared to claimed/promised is due to high dry weight and lower ISP which is 8-10% lower than reported performance figures. They also throttle down the engines a bit, so no wonder NASA is questioning the viability of engines. They can only bring some limited improvements by extending the stages with versions 2 and 3 and adding several hundred tons of fuel, but nothing near 100 tons let alone more than that, rocket equation is a harsh mistress. There is no expendable plan whatsoever, they can’t afford to expend them due to lack of engine production.

>The engines have a built in design flaw that causes water ice to build up in LOX tank which then clogs inlet lines and causes cascading engine failure on relight, this is why the booster keeps exploding. The engine flaw was introduced with Raptor 2 as the parts they deemed "obsolete" or "low value" that got deleted from Raptor 1 involved a standard heat exchanger that wouldn't result in water being produced from preburner combustion and getting frozen once reaching the LOX tank like it is the case with 2, it would only result in gaseous oxygen being put back into the tank as part of the autogenous pressurization. Best part is no part as they say. They're trying to fix this by adding more strainers, but doesn't seem to be working as it only got past boostback before failing again last time. The boostback burn was also off nominal and off course.

>>16150536
>Their HLS interior is almost completely empty with a few bunks on the side and straps for cargo. Yeah, it's bad. For this program Musk prioritized hiring fresh out of college inexperienced people and even those with no background in aerospace whatsoever, and it sure shows with all the rookie mistakes. NASA tells SpaceX it’s not gonna work and SpaceX does it anyway, they’re not listening. This thing can do nothing but eventually launch their V2 Starlinks, if they don't run out of money first, and even that will be compromised due to much lower performance in reality, which won't be good for their already money bleeding Starlink program. As it stands with this performance, it would take around 40 orbital refillings for HLS, so making things a bit better won't help much for it to not be an unworkable and unfeasible concept. It's a total dumpster fire at this point.

Geez, I wonder why SpaceX would rather do the latter. Fucking boomers.

I found a way to stump the chemical rocket faggots of /SFG/!

Have you seen hit movie "Interstellar"? Of course you have, you are space flight enthusiasts. What is the core scientific/mathematical issue put forward in this movie and how does it apply to us in /SFG/?
>The problem of gravity
This is what I preach here on /SFG/, we can not and WILL NOT ever be a multi planet species until we solve the "problem of gravity". Which is the basic idea that when you start computing the amount of mass we must lift off the crust of the Earth to start one self sustaining colony in our solar system it's obvious chemical rockets won't work. Not for one colony and for sure not 100 colonies. So we must solve the problem of gravity and we KNOW via the rocket equation that it CAN NOT be done with chemical rockets. It's basic math, math so basic popular fiction even knows it and explains it with better skill and intelligence than you anons ever could. Sad really.

Now I'm not here to suggest we jump into a black hole to make anti gravity magic wands. I'm just pointing out the undeniable fact that everyone seems to know except the big brains of /SFG/. We will never colonize space with chemical rockets, not now and not in a thousand years. The idea of diminishing returns has been in effect for rocket flight for decades. Vanity projects like Starship show that you can't just build a bigger rocket and even if you do you're still slave to the rocket equation. The sheer insanity of people thinking a poorly designed and poorly constructed silver cock rocket is going to colonize space is astounding.

If chemical rockets can get us to space colonies why did they need to solve the problem of gravity in Interstellar?

well it was in the comments section of a thunderfag video so yeah, watching the video itself was a mistake btw, guy is a lying fuck, making up narratives that don't exist, very shameful grifting.

what will it look like?

Why can't shit-tube just serve the video properly instead of locking up indefinitely?

https://spacenews.com/spacex-making-progress-on-starship-in-space-refueling-technologies/

Silica melts at 3,110 deg F. Lunar reentry is on the order of 5000 deg F. So what's starships gameplan to actually return from anything above LEO?

>>16150734
>what's starships gameplan to actually return from anything above LEO
don't

>>16150733
ah its in development so IFT-4 Ship will still be stuck with Tim's cold cuck thrusters

>>16150734
> Lunar reentry is on the order of 5000 deg F.
huh

>>16150729
Here you go
>>16150734
That temperature is for capsules doing minimal lift reentries, with more surface area and more lift you can do lower temperature reentries

>>16150736
needless to say, you will be going faster than that on entry to the Martian atmosphere, or on a return from Mars. So... is Starship just not designed to take humans to Mars?

>>16150748
the stagnation temperature of the atmosphere is not the same as the maximum temperature the heat shield reaches

>>16150747

oh this is from when we had that schism in the threads after ift-2 right?

>>16150797
jawohl

i've been collecting starship patches since IFT1, I wonder when my cutoff point should be. Maybe after the Mars missions begin?

>>16150724
But muh premium (I use it to listen to long videos in my pocket while at work, relax, I use all protection on desktop)

>>16150802
Nobody cares

>>16150802
are they gonna have a separate patch for each refueling mission?

>>16150802
Never. Just become lord of the patches

>>16150803
you know you can do that with newpipe for free, right?

>>16150805
i hope not, that would really break the bank
>>16150806
it's consistently been $15 per patch. if cadence gets as high as planned, eventually they might stop, except for special or crew missions

>>16150802
why would you stop if you are a collector?

do starlink missions have unique patches?

>>16150810
I guess I'd rather not have piles of starlink patches

elon doesn't really plan to go to mars
he's going be the first person to make $100 trillion by manipulating the mission patch market

>>16150817

they could avoid such embarrassing mistakes by naming everything starship

>>16150643
They even included an automated masturbation device. Why cant we have nice things these days?

>>16150966
they also made it the size of God, which is only sensible
what were they planning on fueling it with?

>>16150975
hydrologgs, hence the volume

>>16150977
yeah okay, the height makes sense then
you'd need raptor-esque thrust density to lift something that tall off the pad if it were loaded with something sensible, like hypergolics or propalox

>Our results suggest that tens to hundreds of planet-sized nomadic worlds might populate the spherical volume centered on Earth and circumscribed by Proxima Centauri, and may thus comprise closer interstellar targets than any planets bound to stars.

>>16150975
>>16150977
second stage was hydrolox, first stage was methalox. as far as i know it's the first time methalox was the preferred propellant for a large rocket stage.

>>16150983
https://arxiv.org/abs/2307.12411
all very well but good luck detecting these exceedingly dim objects

>>16150983
>>16150990
So what you're saying is that interstellar dust has a size distribution

>>16150022
This has been a thing for a while, you just don't hear about it because SpaceX advertises the theoretical max payload rather than what it actually can do as it is now.

The HALO+PPE segments of the Gateway station are the upper end of what Falcon Heavy can lift.

>>16150031
>Is it due to structural issues

It is because it uses the same upper stage as the regular Falcon 9.

>>16150937
That's the temporary hole in the firmament that God makes for every Spacex launch. He does this because He personally chose Elon Musk to lead us into exploring the rest of His creation.
Everyone else's launches are fake and crash into the dome.

>>16150992
>We made a rocket that can lift heavier payloads
>Don't actually launch heavier payloads though, we didn't design for that

>>16150990
so if we were to send some probe to Proxima Centauri we'd have to send at least a few on slightly different trajectories such that at least one gets there?

>>16150997
>Don't actually launch heavier payloads though, we didn't design for that
well, that's true though. it wasn't designed to put 60-ton payloads into LEO because there aren't any 60-ton payloads anyone wants placed into LEO. it was designed for missions like putting viasat 3 into GEO or europa clipper - DIVH-class stuff.

>>16150992
wtf is that Falcon Heavy, that's kino

>>16150990
Would a huge radio/radar telescope do the trick?

>>16150844
>he doesn't know

>>16150997
Falcon Heavy wasn't designed to lift super heavy payloads, it was designed to make Falcon 9 a "high energy" rocket. That is why there are so few launches for it as it is a niche capability.

What went wrong?

>>16151116
he works on HLS. do you mean he's releasing information which legally he is not allowed to? if you are confident that is the case it would be trivial to report him to NASA

>>16151116
nobody cares about your discord nigger drama (may i add with no proof) fuck right back off to where you came from you cancerous little tumour.

>>16151116

>>16151204
It fits the general mood of the 90s. Everyone basically ignored real space except for shuttle flights and just waited for the future to drop into their laps while they dreamed of it.

>>16151260
To be fair one thing we have now we didn't have in the 90s was virtually unlimited funding for space startups

There is an ABSURD amount of liquid capital just sloshing around looking for dumb ideas to wildly overfund. Just look at that dude running Softbank, he's made horrendous bets for the last two decades but he still has billions to burn

>>16151263
The 90s was where a lot of that capital got generated, and Moore's Law became exceedingly kind to dry mass budgets.

>>16151204
anno managed to articulate the post-boomer spiritual crisis of the world failing to become what people were promised decades ahead of most. if it was a disaster for anime then that's an indictment of anime, although i don't think it really was.

How realistic is a full kerolox rocket with 100+ ton to LEO? Because as of now with the limited budget of Roscosmos, focusing on what they do best which is kerolox ORSC is better than trying to create a new RD-0150 hydrolox engine.

>>16151430
If Europa wasn't bad enough, those "people" are making it even worse. I hate that smug attitude backed by pretty much nothing.

>>16151398
i mean n1 could have done 95t with that god awful 1960s soviet tankage and the rd-171's a much better engine than that ever had. there's nothing unrealistic about the concept in of itself. there's plenty unrealistic about roscosmos doing it.

Elon repeatedly says that starbase will be for test launches, and not operational. do you think this is a head fake? building two towers seems like overkill for testing. and theyre gonna need every pad they can possibly get if they want to hit cadence projections

>>16151450
They're all but inevitably going to end up smashing one of those towers to bits while attempting catches.

>>16151450
the prop transfer demo needs two launches in quick succession and right now there's no guarantee that you can pull that off with one pad

Ariane 5 may have been a good rockeet for the late 90s/earlly/ 2000s to GEO launch market, but they utterly failled to make something new.
Especially in the last decade they literally covered theiur eyes and ears instead of getting the fuck going on a re-usable concept.
Which is why we get Ariiane 6, a DOA concept like Antares but it doesn't even fly yet. And will only ever deliver a few national security payloads and some 'I hate Elon Muskj' launches from Jeeff Bezoos.

>>16151452
Pretty sure that empty can will fold like tin foil if it hits the tower. maybe need to replace some piping or the arms, but the tower wont feel a thing

>>16151462
What the fuck is wrong with your keyboard dude

Jeeefff Beeezzoooos

>>16150951
all true though. He says in the post launch press conference that it cost over 1.5 bil (which means it probably cost 3x that due to Elon figures) and he admits he tried to cancel the program many times. Ultimately they couldn't cancel it because they already had DOD contracts

the cognitive effects of CO2 are by far the most important effect in my view and it's shocking that it never gets talked about in popsci. It's all muh trees muh water. Polluting the atmosphere is an obvious great filter. Rome weakened itself through giving everyone lead poisoning and we weaken ourselves through giving everyone CO2 poisoning. The outcome may be the same, and this time the poisoning will be far more permenant.

People on the ISS have all their thinking done externally by mission control. They are 130IQ people who get sent up there and drop to 100IQ, but it's ok because all they have to do is menial tasks thought up by mission control. You only require the IQ of a brick layer to do that.
The fact you can't think in nuance makes me think maybe you are a drooling retard?

>>16151589

>>16151589
the sad part is many anons here don't know this
look up any experiment performed by astronauts, its all shit a high schooler could do.
everything is laid out for them and they are walked through every step back at mission control
and all because NASA refuses to actually fix the CO2 problem(the CO2
exposure might also be causing some the problems that are being labeled as caused by microgravity)

>>16151596
Astronauts IQ probably got lower from drinking Russian pee and eating Russian poop

>>16151596
whenever astronauts have to spend hours setting up an ant farm it's not there to test the ants, it's there to test how retarded the co2's made them.
