>>12277244
if they're really $2 million apiece then it could be cost-effective compared to any rocket besides F9/FH

>>12277244
28, and monetarily it's not that bad but I agree that they won't do it

>>12277241
How? It still uses precision machined aluminum tanks and discarded fairings, it's still going to use a hydromeme upper (Cent-V first then maybe ACES later), it will still have a much slower turnaround time. It's LEO payload is less than half that of Falcon Heavy. It's projected launch cost could be up to the ballpark of $200 mil.

How is a rocket that offers half the performance of FH at (potentially) double the cost competitive with Starship?

>>12277262
i meant serious competition to get to orbit first

>>12277242
If it creates thousands of American jobs you got a deal

>>12277262
>It's LEO payload is less than half that of Falcon Heavy
They're already speccing out a Vulcan Heavy lol. I don't think F9 full thrust existed when they were designing the rocket.

>>12277237
Not too long ago the idea that SS would reach orbit before SLS or F9/FH competitors like Vulcan/NG/Ariane 6 would seem like a bad joke considering how much lead time there was to make up. If it actually happens the oldspace cope will reach unheard of levels.

>>12277263
Depends on how long ULA will take to painstakingly manufacture their lithium-aluminum components, and whether or not their timetable will slip by large margins as has happened in the past with Oldspace. Vulcan is certainly more ambitious than SLS, but it's been in full development for six years now the fact that it's supposedly almost complete is impressive compared to SLS to be sure.
>>12277267
I assume you don't mean the Vulcan Heavy which is the one with 6x SRBs, but the speculative Vulcan set up like Delta-IV and Falcon Heavy with two strap-on cores for boosters? If the costs are relatively similar for all of those, it will then end up costing more like four or six times more than Falcon Heavy, but even if it could hoist twice as much payload as normal Vulcan, say 60-80 tons, that will then still leave it behind Starship which will start flying at 100 tons with a theoretical uprating capability of 150 tons, and at a lower price point with full vehicle reusability while Vulcan still discards the core stage tank and it's upper stage.

Yes, the Vulcan Chubby.

>>12277291
Elon will personally stake him to his coffin by daylight.

>>12277292
Also apparently ACES is on ice right now, so that's going to somewhat limit Vulcan's maximum payload capability by how much the Centaur-V upper can push into orbit without spending too long burning.

>Uses mass engine clustering like the N1 (which exploded every time it launched) and untested meme fuels instead of something reliable like solid rocket boosters or hydrolox
How are you planning to celebrate when the Starship RUDs on the launchpad? Just face it, the SLS is far more reliable and safe than the StN1ship will ever be.

>>12277302
>so completely blown out by the fact his ship is shit and costs too much that he hopes for the failure of another endevour into space.
I hope both of the launched to well... because even them SLS will sill be shit.

>>12277299
As you can adjust the launch profile of the first stage for a higher initial apogeum and the twin engine Centaur-V, I'd expect the burn time of the Centaur to not be much of an issue.

That's what NSF says and that's where the freakout came from in the first place

>>12277270
If their efforts pan out SS is going to change how everyone approaches rocket construction. For the past few decades the notion has been "time and cost don't matter, make everything as expensive as possible". So you get hygromeme 1st stages and isogrids using expensive metals. Then Elon comes along and makes a ship out of cheap-as-dirt steel.

>>12277334
>>12277339
I've actually not heard specifically the "gut the tanks and engines" bit. I doubt it would be that straightforward, but pretty cool if they could make it work. Would be a super comfy home.

I can see it for really serious torch ship construction for 250+ tons of engine and shielding, if you're nervous about nuclear boosters.

>>12277456
Bulk material for assembly in early orbital factories. Rolls of steel, aluminum, kevlar, as well as cables and straps and vacuum welding and fastening equipment and vacuum tolerant adhesives to rapidly manufacture super-large pressurized habitats. In the end, while Elon has so far completely rejected the idea of ever expending a Starship or Superheavy booster for any reason, I think you could at least justify such an expenditure to rapidly accelerate the development of large scale orbital infrastructure.
It would have to be a later generation of Starships though, as is it wouldn't be worth it since the production cycle isn't under way yet.

Regular shipments of bulk materials are the absolutely last case use of an expendable rocket. Why would you waste a $100m rocket to launch 200t when you could launch 150t for $2m over and over and over?

The only use for an expendable Starship would be for a deep space probe where recovery would be impractical (although in most cases you would just factor a kickstage into the payload capacity) or for something meant to permanently stay in vacuum like Moonship. Everything else will need TPS and aero surfaces.

For a rare megastructure/large ship component weighing more than 150t and not able to be assembled in orbit, it'll just wait until the 18m Starship. Beyond that point orbital assembly will be functioning to an extent that everything will be built in orbit anyway.

$500 for the terminal is pretty high for outdoor equipment and self installation, it had better come with a good warranty.
They need to get the monthly cost down before wide release too, or at least have a cheaper package with lower speeds. If they could do 25-50Mbps for $50/mo with good connectivity they would instantly obliterate every single rural ISP.

If they can't get the price down before wide release they just need to have a solid warranty or lease option on it because a certain percentage of them WILL get damaged by weather, especially if they're going to rely on customers to self install them.

Reduced launch count which is all that matters. Reduced risk to human lives and mission integrity. This is why even today countries including the United States continue to develop and optimize advanced high efficient one-use rockets that could allow us to reach Mars one day.

You should raise the stakes by then telling them that the New Madrid fault line is behind schedule. Quakes are felt a lot farther in that part of the country, also there are reports that the top ten feet of the ground just hopped up and flipped over.

>>12278374
I'd be less concerned about yellowstone and more about flood bassalt volcano forming slowly under Iceland. Yellowstone is the nearly dead ember of a much older flood bassalt, each of the eruptions we know as Yellowstone were really just the post-eruption puffs of a much larger and more powerful volcano. While Yellowstone may not even have the juice to go off ever again, once the Iceland Flood Bassalt is ready to blow it's a guaranteed mass extinction event for 90%+ of Earth life.
No amount of solar panels or green energy will solve that problem, there is not a number of climate telescopes that can be launched which will prevent it from erupting, once it starts going off we've got a pretty hard 100,000 year deadline before the beginning of a total collapse of the biosphere.

>>12278159
all those stupid sci fi contraptions (looking at you isaac arthur) fall flat on their faces once you realise that building a 100km rotating ring with 1g would be equivalent to building a 100km long bridge on earth with no support structure

>would be equivalent to building a 100km long bridge on earth with no support structure
That's not actualy true, the ring would only experience tensile stress while a bridge experiences bending stress, wich is a significant difference.
Allthough 100 km diameter would be ludicrous and overkill.
Something like 100 m however would be doable.

No? In term of basic mechanical engineering, if you have a material with a high enough specific strength (https://en.wikipedia.org/wiki/Specific_strength)), you can build a 100km ring and spin it, and it will hold.

>>12278433

>>12278374
These fucking idiots forget that mass extinction events are routine. And we're due for one. They're so absorbed in their luxury beliefs and irrelevant minutia that they forget where they are. This universe is a dangerous place for life. Earth is about as good as it gets but it's just a microscopic oasis in an endless hostile expanse. And even this oasis breaks down from time to time.

The only hope humanity has for long-term survival is to 1. advance technologically to the point that we're no longer 100% at the mercy of this reality's whims and to 2. obtain the maturity to use said technological prowess constructively instead of against each other. This is obviously very difficult, which is why I believe that the great filter is real.

The main advantages of full flow staged combustion are:
>closed cycle
No fuel is dumped outside of the combustion chamber.
>oxydizer and fuel are a gas when injected
This raises the the combustion efficiency as the gasses mix and burn quicker.

This does have a huge challenge though:
The oxygen rich preburner and turbine are subjected to a stream of very hot oxygen/combustion products mix.
That has a tendency to light stuff like metals on fire.

>It's sad to see a once world leader become a joke like this.
You're 50-60 years late and not particularly accurate. What's happened is that whilst there has been some loss of capability more significant is that few countries still produce a whole plane themselves because the risks are so great they have to spread it around and that the UK still has some of the most advanced aero capabilities on earth. See the Panavia Tornado and the Euro fighter for examples of UK participation in Euro projects, and F35 where Rolls Royce build the lift fan plus a fair few other bits. It's certainly true that the UK is virtually a client state of the US militarily though, but again you are merely stating something that's been known for decades. I mean the US has supplied UK with ICBMs since the 60s. I'd suggest you're speaking from a position of ignorance.

>>12278803
How the heck do you know that? Sounds like asspull

>>12278755
yeah, seems assured we'll do one more static fire from the main tanks. if all goes well, they'll move forward to do a firing from the headers. then and only then will we have a good guess as to when it hops. my personal guess is NET November 15, before December 31 :^)

But you mentioned aerospace and fighters which are both aero rather than space. On space I agree to an extent because the UK has some fine engineers and scientists and it's a crying shame that they have been denied opportunities and that the world has been denied the chance to see what the UK could do (HTP is cool). But OTOH every other org apart from SpaceX are currently looking pretty unwell about about the prospect of being obsoleted at a stroke by Starship, with Roscosmos and Arianespace in particular looking at their decades of investment turning out to be an actual hindrance to future success. Being heroically optimistic: at least the UK has no laughably terrible oldspace sector to hold it back.

They have not, but I assume if they are sending boots on the ground they are also going to sign the accords for resource usage. Probably just haggling over the fine print over signing onto what could become the new precedent for space resource extraction.

>Being heroically optimistic: at least the UK has no laughably terrible oldspace sector to hold it back.
This is unironically a good thing at this point, you don't want to be heavily invested in incumbent industry when disruption comes along. The biggest problem for the UK right now is not its history but its modern day reality. The old and slow dying off is only good if new blood moves in.

I think if the UK had of funded SABER themselves instead of letting BAE buy it that would have had potential to do suborbital space tourism and zero g experiments cheaper than anything else. Now we won't hear anything about it for 40 years until the hypersonic missile it drives is declassified.
As for Roscosmos they were looking into recovering booster decades ago so I don't think they are as far behind as say ULA.
Arianespace will be kept alive by EU government launches but does have a lot of catching up to do if they want commercial launches that aren't forced on them by EU governments taxing companies that use SpaceX.

The UK government has never had any desire to do anything that doesn't immediately line their pockets before the next election cycle

Lack of starship updates after they put on the nose cone because they needed to do a raptor swap. Normal space flight news is a really slow drip.

Generals become cesspits without focus. Go to /vg/ and notice how 90% of the generals are some bizarre subculture that doesn't even talk about the topic game anymore

I'm very aware, I just thought the high IQs at /sci/ were better then that.

I wish we had more english info on JAXA and CNSA, both are doing interesting things we hardly hear about in the west.

Soijackers are a group of autists who congregate on their own gay little chan called soijackparty in order to organize raids on random boards. A week or two back they tried spamming /po/'s oldest thread off the board just because 'fuck 4chan lolol'.
I think their average age is 19.

Its just particularly bad because an extremely heated re-election is around the corner and both sides are absolutely sure they are going to win so its political shitposting all-round. Should simmer down once one of the candidates hits 270.

There was a major comet strike about 9600 BC that melted the Pleistocene ice sheets and spawned flood myths in almost every surviving culture.

Any progress from the anons making their own rocket parts?

>>12279055
It hit the NA ice sheet, right? I've not heard any speculation on alternative impact sites for that event.

>>12279059
Last I heard the impact site was somewhere in Canada.

>>12278374
Yellowstone isn't going to erupt any time soon. The whole "it's overdue" argument is ridiculous. You should be more concerned with >>12278407 (a really scary problem) and even more scared about an impact event which, while unlikely, can strike without warning and fuck up the whole Earth. But yeah flood basalts are probably the scariest and have the capacity to kill 99% of life on Earth in the blink of a geologic eye (see the Permian-Triassic mass extinction event)

What would be an appropriate alloy to use for the heat exchanger of a nuclear thermal rocket?

probability says we go extinct naturally long before some "extinction event". all other members of the homo genus within the last few million years are gone

The one with the highest melting point, you don't care if it takes a lot time to heat up and the hotter it gets the higher the ISP.

How are these people still not aware that if you can get Comcast then Starlink probably isnt going to be an option for you? Starlink is for people in very rural environments where traditional telecoms are unlikely to provide service.

>>12279082
It’s impossible for humans to “go extinct naturally”.

>>12279082
Surviving previous extinctions does not guarantee you will survive the next. Trilobites are the best example. Dominated the Earth even after everything else got killed off, only to get wiped out when things got too bad. Never underestimate extinction events. The only reason we have made it this far is pure chance

>>12279086
