That feels absurd for an engine that didn't even fly an orbital mission yet.
Wonder how many BE-4 were built, since they claimed it was a "hardware-rich" development program...

>>14961695
Once Starship goes to orbit and proves its success, we'll see once a month Starship build/launch

Today I will remind them
>The cost of the Mir programme was estimated by former RKA General Director Yuri Koptev in 2001 as $4.2 billion over its lifetime (including development, assembly and orbital operation).
Cost of MIR was as much as 1 (one) SLS launch

>>14961701
Also note that MIR and Salyut-7's Soyuz T-15 is the first and only time that a spacecraft has visited between two space stations
>Soyuz T-15 (Russian: Coюз T-15, Union T-15) was a crewed mission to the Mir and Salyut 7 space stations and was part of the Soyuz programme. It marked the final flight of the Soyuz-T spacecraft, the third generation Soyuz spacecraft, which had been in service for seven years from 1979 to 1986.[1] This mission marked the first time that a spacecraft visited, and docked with, two space stations in the same mission.

Do you always ask questions direct from a Stack Exchange post or just this one?
https://space.stackexchange.com/questions/6135/why-was-the-iss-so-much-more-expensive-than-mir

MIR makes me extremely sad. The ISS is a good idea, but with the different system of pork in the US, it just becomes an inefficient system.
Russia has a good system in the fact that the rockets are cheap, and the budgets are consistent. The shuttle and it's consequences have been a disaster for space exploration

>>14961725
90% of that is the standard embezzlement tax

3 stamps from the Soviet Union, 1981-1986
First one is technically two stamps, but the new one is a sidepiece to an already existing stamp

>>14961777

The two others are not a part of any series of stamps, just singular ones. Simple cosmonautics day stamp from 1984

>>14961780
And lastly the stamp made for world Expo 1986, showing the Salyut and Soyuz that were on display at the expo

>>14961746
Well, to be fair, a non-negligible part of the 200 raptors are development engines that will never fly, but still, the contrast is quite impressive.
Plus it also means that SpaceX is producing them quite cheaply, as they couldn't build that many if they were 10M$ (or even 1M$) each

How long until all construction of starship is moved to Florida and boca Chica is abandoned rofl

>>14961830
Boca Chica is R&D, when Starship leaves that means they're working on HLS/Tanker

>>14961830
?
rofl

>>14961835
They've been working on HLS for quite a while.

>>14961449
This helicopter catching scheme doesn't seem like it can ever work reliably. Why can't they just put a foldout wing and some wheels on the booster and fly it back to land like an airplane?

>>14961837
The systems, sure, but the HLS Starship chassis hasn't been fabricated yet as far as I know

>>14961841
S26 and S27 are HLS test articles.

>>14961839
I guess wings would add too much mass and take away from the payload, but I wonder why this type of reusability hasn't been tried as much.

>>14961835
Boca Chica is only R&D in Musk's public statements. This buys time, and keeps activists off SpaceX's ass. Behind the scenes SpaceX is lobbying 100% to fully incorporate Starbase into its own city, and change the laws to allow a pretty intense launch cadence. He'll get his natural gas plant and second launch tower too, and that's just the beginning. The ones shafted will be South Padre residents, but by the time they realize it Texas politicians will be convinced the regional value of Starbase far outweighs the tourism and NIMBYs of South Padre. Chances are, SpaceX will first colonize South Padre with Starlink money as a dry run before shifting to Mars.

https://www.youtube.com/watch?v=RsxjKNNsqvQ

>>14961847
Yeah they would need a beefier booster to handle horizontal landings. Too late to do that for Electron though since Neutron is their way forward. They should just add some airbags and mount the parachute in the rear so the booster lands in the sea nose-first to keep the engines out of the water.

>>14961882

>>14961889

>>14961850
>outweighs the tourism
Starbase/Starship will double the tourism with all the roggedwadchers.

>>14961891
exactly

>>14961888
Then you make one

>>14961891
I believe the plan is to have it "land" on water, just like the early F9 landing tests. Except this one should be able to hover, so it won't just hoverslam into the water.

>>14961882
I will still give RL the benefit of the doubt for the heli catching since it's just their second attempt.

>>14961886
For New Zealand launches maybe they could land the booster on a deep snowbank in Antarctica. Wouldn't even need airbags if they can land on soft powdery snow.

>>14961901
but they will risk it falling out of the edge

Why didn’t people start using methalox decades ago

Wonder if these unsuccessful Electron snaggings will influence ULA's plans to recover their own engines via helicopter

>>14961906
Methalox is hard to get right. CFD software and cheap computation power weren't available to ease the development processes along until recently, and nobody was reviewing the old priors until SpaceX.

>>14961906
Why should they? If NASA/Airforce did want it, why should companies make their own to create their own market?

In other words, because they didn't feel like it.

>>14961906
Muh hypergolics
Muh efficiency
Muh military applications

The long answer is liquid forms of gases are relatively new (within that last 100 years). Keeps large quantities of them on hand was expensive and complicated. The military didn't want them for these reasons, so they pursed hypergols instead of super cooled fuels.

"Ignition" is a great book and everyone here should read it.

>>14961915
But surely methane isn’t easier to contain in a liquid form than hydrogen, and just outright easier to source as well since it’s mass produced from multiple fossil fuel sources, like coal gas.

There's no point in building a rocket engine without a rocket to use it, and the recent Cambrian explosion of new launch vehicles isn't anything like the historical norm. Methane didn't have any serious advantages over RP1 and most people were still hypnotized by hydrogen.

People haven't cut off their legs yet. So they can still walk. It just means people have more options.

>>14961915
>>14962076
The military wanted hypergols so they could just leave them loaded for fast launch. The Nike SAMs still ran on hydrazine and red fuming nitric acid into the 70s, when they were replaced with solids.

>the most valuable institution in the world

>>14962278
I wonder what the MPGe for EV would be in a tunnel with near vacuum air resistance. For ICE cars, it would be inoperable, but with EVs, the MPGe might be well into 500-600+ miles.

Would the establishment of company towns for large scale mining operations in space be a legitimate way forward for Human colonization of space? Surely something like large scale manufacturing in space would necessitate a decent sized workforce relatively speaking that could be kept in a large spinhab, which could then branch out to other small colonies since at that point because you're already in space, mining operations would be economically viable to support the population conducting the manufacturing in orbit.

>>14962319
Thats one possibility. Another possibility is using AI robotic mining machines to establish the mining operations and then humans may play some minor roles

NASA still has not learned from their secret-keeping ways with John Glenn's flight, have they?

>>14962345
I feel like people greatly exaggerate the capabilities of AI and robotics at replacing human beings for even seemingly simple tasks. Something as simple as taking someone's order at McDonalds is borderline impossible for AI to do. I'm sure if you had manufacturing in space at scales that could compete against Earth based products, you're gonna probably need to have a decent amount of people up there making sure that when shit eventually fucks up, they're there to fix it while also being there to do the jobs that are just flat out impossible to do for AI.

>>14962278
>Batteries and electronics overheat

>>14962360
>I feel like people greatly exaggerate the capabilities of AI and robotics at replacing human beings for even seemingly simple tasks.
In short term, thats true, but in long term, its absolutely not true.

Remember, the modern AI did not exist 10 years ago. The rapid use of AI in everything today is astounding imo. Give it another 50 years, what will AI use in 2070 be like? I would reckon it will shit on almost any human cognitive and physical task.

>>14962363
Radiators are included and little bit of air resistance is there for the system since hyperloop works with little airflowing under the car.

>>14962363
>Reminder that heat dissipation is a massive problem for spacecraft. Starship is going to boil everyone inside alive

>>14962204
Lol

Lmao even

>>14962204
*waddle

The dude is just fishing for (you)s but is nonetheless right. Look at the giant solar and radiator arrays the ISS has for a fraction of the volume and life support capacity of starship. True a lot of it is for science junk and is a bit dated but still. You can't just handwave it away with "lol it just folds out bro". Even if you built a JWST tier origami radiator and solar array it would take a up a pretty fucking big portion of the payload bay.

>>14962437
Starship is made of metal tho, it should radiate some away all on its own right?

>Plasma magnet sail man will never get the funding he needs for tech demonstration
>We will never have an Aldrin cycler

>>14962443
Er I mean I suppose you could just have a few mm of stainless steel between the crew and the void which would help some, but you want them to not die of radiation so you need a thick radiation barrier of foam or something similar which will be a great insulator. Also you are getting 24/7 heat from the sun which you need to reject too, ISS has the advantage of being in the earth's umbra for half the time.

>>14962467
You don't

>>14961966
Makes sense. A rocket engine should be able to survive a brief exposure to seawater as long as it isn't red hot when it splashes down and if they purge it with fresh water shortly after retrieval. The engine section isn't going to be floating in the sea for weeks or months after all. Maybe a few hours at most if they have a ship standing by. Would also help to have some valves they could close off to prevent seawater from getting too far into the engine innards.

Why the fuck isn’t the first step for any type of space program intending to go beyond Earth escape velocity not to establish a propellant depot? Quite literally every single problem encountered in these missions/programs would be eliminated with that one step.

>>14962615
Please fund SLS Block 2

>>14962622
How new are you

>>14962622
because Congress assumed anything that made spaceflight more practical meant taking aerospace jobs and money away from their states. in reality it probably would create more jobs and require more launches, but no one said politicians were rational

If SLS and Orion didnt exist, what is SpaceX's ideal lunar architecture?
I think it's launch astronauts on starship, launch hls separate, refuel hls at depot, crew transfer from Starship to hls, go to moon, land, return to earth, crew transfer to Starship, land on Earth

>>14962630
Couldn't they just do all with the same Starship? (not counting the fuellers of course)

>>14962631
I don't think hls has thermal protection. It's purely just for the moon.

>>14962632
which is a shame because it'd be fucking sick being able to bring back the lander and put it in a museum or something

>>14962630
>If SLS and Orion didnt exist
SpaceX wouldn't be bothering with the Moon lmao. They're only making HLS to build (part of) Starship, for free.

>>14962630
They wouldn't be going to the moon or building HLS without NASA. They only accepted because it's a fairly simple modification of starship and they get a giant chunk of change to throw at the starship development budget. If they did do it by themselves though the architecture would just be starship and superheavy. Nothing else.

>>14962632
and I wonder, would spacex have even bothered doing a purpose-built lunar HLS, if they werent trying to win a NASA contract? maybe they would have been content with flying the flaps abd heatshield to the moon and back, but with a large mass penalty.

Another question: Does SpaceX really need a depot in orbit? Why cant the just ass2ass every refuel flight?

Easier to have a depot do it and optimize the depot ship for more fuel storage.

They could have starship dock to multiple starships before fully refuling, but that puts mission in unnecessary risk. Its better to let the tanker ship be refueled months in advance, then when the time comes to launch, have Starship refuel once in orbit and then go to mission.l

>>14962644
Yes because you can have a mega depot that is ready to go all the time and topped up whenever is convienient rather than having to scramble a dozen flights all at the same time for one payload.

>>14962646
Further more, with a tanker, they can constantly launch Starships in even whenever they want and be ready for any deep space mission when necessary. It basically cuts operations risk factor a lot.

A depot's main purpose is to eliminate boil off of the cryogenic propellants, instead off flying the equipment necessary on every tanker trip, just launch it once on a depot

>>14962677
>Boil
Unironically what would be the point of using LH2 after establishing propellant depots? Just use Methane or RP-1 until you reach the point where you're using propellant as remass for nuclear fission/fusion fuck you drives for when you need the v-tec to kick in.

>>14962615
the problems are manifold:
Orion is oversized
Service Module is undersized
hydrologgs means the upper stage can ONLY be used for TLI and must be ditched afterwards

this means that the Orion Service Module doesn't have enough dV to insert into a LLO and then get back out again, so they need to go to NRHO instead

NRHO is cool though, the toolbooth is cool

When the government isn't paying for throwaway ships there is a pretty large financial incentive to bring your expensive ass investment back safely.

>>14962703
Already a solved problem. You use the boil-off gas for station-keeping propulsion. propulsion

It's not like putting a pile of fuel cans in the desert, just getting there is a toll booth that forces launch windows on you. It might be okay with a bunch of similar missions, or saving up ten launches of fuel for a big mission, but a general Buc'ees kind of depot won't work.
I guess it might be possible in L4/L5 for BEO missions, but we still haven't even gone there yet.

Supposing everyone became a billionaire overnight, they would complain about quadrillionaires.

Even if there was suddenly a lot of certain kinds of previously expensive metal there would just be a drop in the prices of those metals.

Behold! The road that Richard Shelby made

>>14963392
Did the rocks really have to be from Alabama? Why not just walk down to the beach and grab some from the Florida shores?

>>14963395
The rocks actually do have a very specific set of qualities that let them provide the right traction when the crawler rolls over them. You can't just use any old rock sourced from anywhere, and they need to be present in a source in a large enough quantity for mining them to be cost effective.

That said, there's zero reason for them to have to come specifically from Alabama. There's plenty of places that could produce the right kind of rock in the needed quantities.

>>14963403
Fucking Shelby, the thought of rocks being sourced out of a river by hand and then shipped by rail all the way down to Florida is just ridiculous. There must have been a closer source of the right kind of rocks, what a waste.
At least somebody gets a job of going out and raking the crawlerway smooth every time SLS has to go back into time-out.

>Of the 200 Raptor 2's, a fair percentage have been selected for testing to the limit or beyond, and won't be used again. There is a percentage tested prior to production line assembly which have not met performance criteria, due to build quality, and can't be used. Now that production is in line, quality has improved immensely with engines matching each other in performance with assured startup, run and shutdown reliability.
>Not counting the engines currently fitted, I'd guess there are around 40 selected engines waiting at McGregor, So they are just keeping ahead.
>The issue of course is getting the ground systems up to speed, and testing B7 and the outcome of testing 16 and 33 engines. Provided there isn't considerable damage after one or both tests, the entire GSE and Rocket systems will require refining for flight.
>It's not a bottleneck, just there is an incredible amount to still refit, fit, test, run, repair, do again, etc.
>NASA reckons December launch, but I wouldn't put a bet on that.
>Keep an eye on when a WB-57 moves to Hawaii, and if one or two of the SpaceX recovery ships go for the Panama Canal. Also look for a gap in SpaceX launches..That will be your 3 week lookahead.

Anyone have that short paper that was posted here several months ago about the effects that lowering cost of energy would have as solar and eventually fusion developed?

Why did NASA choose to go with Orion? If SLS wasn't bad enough, that capsule ruins their whole Moon program.

>>14963412
They don't actually collect the rocks by hand. Repaving the crawlerway takes tens of thousands of tons of rock, and you can't just gather that up manually. My guess would be that they dredge up a lot of river sediment and then sieve out all the mud and smaller particulates until they've got material that meets their requirements.

And their might not actually be a source in Florida that works. The rocks are specific flavor of quartz, which gives them the right compression resistance and crush qualities. The rocks also have to be rounded so they behave less like a solid and more like a viscous, slow-moving liquid when the crawler rolls over them. This is apparently important for providing adequate support and traction. Alabama rocks are eroded out of their quartzite bedrock and then rounded when the water carries them downstream like a tumbler. Florida is mostly sediment built up on top of old coral beds, so there might not be any good quartz anywhere in the state, and it isn't exactly known for having stony-bottomed rivers either. Alabama might actually be the closest source of the stuff.

But closest doesn't mean cheapest. NASA could have got a better deal if Alabama, Tennessee and West Virginia had all placed bids for the project.

>>14963444
Before we even can think about the launch, SpaceX has to perform a WDR, static fire, and receive a launch license from the FAA.

Quality roggpost

What's the weight of the whole thing (crawler-transporter, mobile launcher platform, SLS)?

>>14962535
I am.
Velo 3D makes powder-deposition metal 3D printers that Spacex has used to make parts of most of their engines, Raptor and Raptor 2 included. Spacex actually pre-bought a bunch of the company's next-gen printers to help fund the completion of that product. Musk asked to buy them a few years ago and they decided to IPO instead, and stock tanked out of the gate from $10 to ~$2.50, which is where I bought.
Their revenue growth recently is bonkers, and I'm willing to bet a good slice of that is from Spacex building out a Raptor mass-production line. Their next earnings call is election day.

>>14962622

And no, that's not a joke or exaggeration or conflation of an industrywide sentiment to one man. Shelby wanted money coming to his Alabama contractors for BIG ROCKET so he murdered propellant depots in the crib.

Congress and because it is was already developed during Constellation.

>>14963578

>>14963578
The crawlerway only needs to be resurfaced once or twice a decade.

And they didn't use rails because evil always hate things that are good and congress can't do anything without some part of it being hopelessly retarded.

Fuck rails. Use boats.

>>14963596
Looking at it right now it already looks like it needs a rock tender to come rake it smooth again.

>>14963607
Regrading isn't nearly as intensive as resurfacing. It's the difference between putting a patch on a pothole and tearing out all the asphalt so you can replace the substrate.
