>>16108162
As the wise man has said prototypes are easy production is hard.

>>16108152
Nuclear/electric, specifically nuclear powered Microwave Electrothermal engines. They extremely simple designs, they can use water for propellant so propellant storage and cost are no where near what you'd get if you're putting up with xenon or LH2, you get 1000+ sec isp, and they're far easier to cluster than classic ion engines. They're power hogs like every other electrically-driven propulsion system, but if you're including a multi-megawatt reactor that's not an issue.

Spacecraft need onboard propulsion and station keeping with cryogens is not economical. Even assuming you're right about nuclear thermal and fusion thrusters, solar electric's niche as a low-thrust, high ISP station keeping or maneuvering thruster is secure.

they do that all the time newfriend.

>>16108313

They are just large candles

You're a retard if you don't see the analogy.
Pressure fed rockets have to contain the chamber pressure in the fuel tank.
So do srbs.

>>16108318
Fuck off nigger

>>16108323
>seething immediately

>>16108152
Chemical, solar electric, nuclear electric, in that order

Speaking of SRBs, how do large SRBs cool the nozzles?
Liquid rockets run fluid over the nozzle, hobby rockets have very beefy nozzles and only burn for a few seconds. The nozzles on the shuttle SRBs and GEMs look comparatively thin and don’t have a large pool of cold fluid to draw from. What’s their trick?

>>16108329
They're ablative nozzles.

>>16108116
what are these trails that don't match rotation?

>>16108330
That makes sense. Any reason expendable liquid engines don’t also?

>>16108329
The Shuttle boosters burned away several inches of steel during their flight. There was no cooling, the thermal flux was high enough that it overwhelmed the thermal conductivity of the steel and burned it away. Just another point against solids for space launch.

>>16108334
They do. The first merlins used ablative chambers.

>>16108334
Plenty of them do. The RS-68 was semi-infamous for having ablative nozzles.

>>16108334
Ablative nozzles fucking suck. They're heavier and they aren't any cheaper than a modern regeneratively cooled nozzle (which have come waaaaay down in cost)

>>16108337
The nozzle insides are phenolic and carbon.
You cant just use steel without an ablator.

>>16108340
>modern regeneratively cooled nozzle (which have come waaaaay down in cost)
only if you're a gay proonter fag which would be gay and faggy

>>16108351
Gimme ur bussy

>>16108249
more like nearMoon because they don't land
or queerMoon if you look at the passenger list

>>16108342
They are solid steel inside of SRBs. No phenolics.

Martian methane production has been solved
https://twitter.com/TerraformIndies/status/1774848332634149102

>>16108351
No, the modern way of making regeneraticely cooled nozzles (a sandwich of milled channels) is as cheap as the older ablative nozzles and far cheaper than the bundle of tubes method.

>>16108282
>thing that doesn't exist will replace cheap and effective thing in widedpread use

>>16108377
The nozzle certainly has and that is what was asked about. Inside the casing there is fuel which insulates the walls from the combustion until it's almost done.

>>16108318
>SRB
>fuel tank

at least use hybrids as your example to not look dumb

>>16108340

>>16108395
>ablatives are cheaper
Not significantly, not anymore. Raptor is less than $1m apiece in total, the nozzle probably takes up no more than 5% of that cost, ie around $50,000. I bet the ablative nozzles of the RS-68 cost more than Raptor's nozzles.
>cannot do any sort of expander cycle
Total non factor for pretty much any engine in existence. Lack of reusability is the real killer.

I said SRB. You said hybrid. I am not talking about hybrids.
You taking issue with the word fuel tank for SRBs is just due to your mental retardation.

>>16108427
and an ablative Raptor would be cheaper still, at the cost of dry mass and reusability

>>16108427
>I bet the ablative nozzles of the RS-68 cost more than Raptor's nozzles
Like all good oldspace projects, AJR outsourced parts of the RS-68 to subcontractors. Thiokol was selected to produce the ablative nozzles owing to their similar work on nozzles for the Space Shuttle SRBs. I think being more expensive than a SpaceX project is a given.

>>16108512
I want to say one word to you. Just one word.
Plastics

>>16108512
Hydrocarbons are very efficient for storage density and on-demand utilization, and it's very cheap to store and transport. Electricity, by comparison, is not cheap to store at all.

>>16108512
it gives the desired wok hei aroma to the food when you stir fry over a high btu gas burner.

>>16108515
>most of the way
no, it's very very far from being a fusion propulsion system.

>>16108526
Helion's reactor design is just two big ELFs pointed at each other running in reverse.

Living beings were never meant to leave Earth's atmosphere. Outer space is just too cold and too rough.

it is definitionaly carbon neutral to take hydrocarbons out of the air and burn them for fuel by the way

Hominids were never meant to leave Africa. Eurasia is just too cold and too rough.

>>16108544
no man, helios' reactor needs to produxe far higher energies and compression ratios to approach fusion conditions, and even so, if they do achieve a self sustaining fusion reactor, it won't be trivial to turn that into an engine for spacecraft, and that engine would be very different from ELF, too.

Roscosmos

In Baltimore, Maryland, the Francis Scott Key Road bridge over the Patapsco River collapsed.
The container ship MV Dali, which collided with a support beam, with a length of 300 meters and a displacement of about 100 thousand tons, was sailing under the flag of Singapore from Baltimore to the largest city of Sri Lanka, Colombo.
Now the port is blocked and navigation is impossible until the debris is removed and the bottom is cleared. Naval ships are also stuck at the berths. The management of the port and the city is going to create a temporary canal in the northeastern part of the main canal, in the area of the bridge. This will allow ships with the most important cargoes to pass through the channel.

He really is a bastard. Cattle droppings are critical to making marginal lands fertile and able to sustain plant growth, and it's a hugely important ecological niche for improving landscapes all around.

>>16109597
if we can use less land area for the same amount of calorie production for humans, then old farmland and cattle grazing area etc can be rewilded
actual wilderness is a much bigger improvement compared to farmland

>>16109599
Cattle graze *on* wild landscapes. They're not waltzing around in maintained pastures, they're eating in what's almost nothing but useless shitty barrens that are no good for farming.

>>16109602
those are not wild, for one there are no predators that hunt cattle freely, and the landscapes do not support wild grazers as much because you have cattle there and so on
grazing lands are now wild

>>16109605
so?

>>16109605
The lack of major predators doesn't make any real difference. The Great Plains of the United States didn't have any major predators either, and tens of millions of bison roamed them.

Not spaceflight shut the fuck up

>>16108124
Not a rocket scientist, but I suspect they want to make the rocket cheap by making it reusable

>>16109606
why keep an area like that to graze cattle when you could rewild it and use it for recreation, biodiversity and so on

>>16109611
lol yes they did

>>16109619
if "biodiversity" means wolves taking over i'd rather live somewhere with grazing cattle

>>16109619

Because getting rid of the cows reduces biodiversity and makes it worse you mouth breathing dumbfuck

>>16109621
https://www.youtube.com/watch?v=fTPt70vA39k

nope, actual wild animals would populate the area

What happened to Mars? Wasn't it near enough the same size as Earth? Did the NPC admins decide to shrink it and buff it so that going there isn't a mistake?

>>16109636
humans habitate cities mostly, you could rewild big patches of land in the hypotethical scenario we are talking about and have some non-farm,non-grazing but still not-completely rewilded areas for people to live in that don't want to live cities

https://ourworldindata.org/land-use

>>16109639
are you retarded? the point here is that if you could make the same food synthetically using solar power, the land would be much more valuable to use for solar power
but that would be so much more efficient that you wouldn't need to use nearly as much as agriculture and grazing use nowadays
grazing cattle and farming monoculture grain or something is worse for biodiversity than actual just wilderness, no matter what kind of weird mental gymnastics you are trying to do here
and obviously you wouldn't do rewilding before you had something like this running and it wouldn't be forced
it would happen naturally (and I'm saying its good it would happen) just by solar powered artificial foodstock outcompeting farming and grazing

>>16109636
Why the fuck are you blaming cattle for a deer problem?
>>16109650
You literally can't do that you dense motherfucker! Humans are omnivorous! Our biology IS NOT OPTIMIZED for the exclusive consumption of plants! Every single human being, outside of mutations, genetic defects, and similar cases that are irrelevant rounding errors, benefits from having significant quantities of meat in their diet! Harping about efficiency is the height of malice or idiocy.

What kind of fast food joints will there be on Mars?

>>16109653
plants? you can create proteins with yeast
you might be able to recreate most foods without actual animals in the future and more efficiently than actual using the agriculture -> animal -> meat route

They're just totally unaware that boosters are hitting 20 flights reliably now. Just ignore them, it's genuinely some kind of psychosis. For whatever reason they can't learn, it would break their minds.

>>16109837
60% compared to fucking what?
What engine architecture? What fuel volume?

Nuclear is based but it makes no sense for anything happening near-earth.
NTR shines the most when doing missions to mars or further because of the ISP gains, but it give you fuck-all for thrust.
It also relies on hydrogen for for all that ISP, which you get double pounded in the mass with NTR. That nuclear reactor is fucking heavy, and the containment for the hydrogen is a massive bitch as well.

Upon their ignition, the chambers/grenades might have fed hot propulsive gas into a single or multiple combustion chambers at the center of the contraption, producing either the main thrust and/or steering the vehicle. When the missile reached the proximity of the target, according to its guiding radar, the entire vehicle would explode and the small solid chambers would eject under their own propulsive force in every direction acting as shrapnel.

>>16110024
No, and very no. ICPS has a 5m diameter and that really doesn't like the idea of having to perch on a skinny boy like the 3.7m Falcon. Centaur V is even worse at 5.4m, and the EUS is an absurd 8.4m across. If you really wanted to try making a nightmarish frankenrocket you could maybe put an EUS above a bundle of 3-4 Falcon boosters, but you'd need to subtract the standard Falcon second stage and engineering that cluster would probably be as much a headache as getting the Falcon Heavy to work originally. It's within the realm of possible but not the realm of the recommended.

Like I said a few threads ago in response to someone quoting Shotwell on regulatory hurdles: if they don't get input on those rules they're going to be run over by them. Right now the ITU is busy making angry noises at NGSO operators because they don't respect national frequency allocations or borders, and this is one hundred percent about Ukraine and Starlink

Welp guess EU wont have Starlink. Not like they made many sales there anyways since most of EU is just cities. Thats too bad, but theyre 100% going to try to limit how many satellites each company can put up so SpaceX cant be part of that. Not like anyone would EVER want to have launch pads in Europe either.

>>16110247

>>16110238

I doubt that it's about Ukraine since they allowed SpaceX to operate, broadcasting without permission as a non-state actor is generally frowned upon I'm pretty sure, the ITU works because everyone mostly respects spectrum allocations and broadcast rules, if people were to get away with just ignoring them it could lead to a shitshow.
