Yeah nah lmao

>>11165925
They were pushing the trashcan through the highest pressures, so they were actually expecting it. I guess even Musky knew his crinkly prototype would not last and is investing in MK2.

Don't worry guys i-it happened on purpose

>>11165915
Wasn't this built so the front wouldn't fall off?

Maybe the explosion was on purpose, and was simply Musk punishing Boca Chica for some perceived failure

Pic related is what an actual cryogenic burst test looks like, notice the lack of large control surfaces and complex actuating systems like those that were built for Mk1. It’s clear that it was originally meant to fly. If SpaceX actually planned to destroy it, the decision was made very recently when they realised it was so poorly put together that the only useful thing they could do is destroy it and start from scratch. Which is even worse IMO...

>>11165931
Thats a petty excuse desu.

>>11165959
I hate to say it... but this is probably the beginning of development problems for starship. There is no way that these things are being built to the standards needed to actually fly. I'm becoming more and more concerned that this whole 'cheap and fast' method of development isn't going to work out.

Here's an interesting rumor, supposedly from the SpaceX Boca Chica Facebook group:

> RUPTURE UPDATE:
> Through back channels it has been revealed that MK1 suffered an accidental overpressure to failure. Fuel and oxidizer would typically be loaded to 3 Bar or 43.5 psi~ for densification purposes and flightworthy tanks may be tested to 1.5-2x that value for single time structural proofing. In the case of what happened today the story is that communications errors between the pumps/sensors and remote controls allowed the tanks to be massively and erroneously overpressured to the point of failure, leading to catastrophic rupture.

I don't faceberg, so I can't confirm this. But if true, it means the welds were not out of spec, instead it was the tank pressure that was out of spec.

>>11165968
Rumor was also that Elon landed a while ago to state that Mk1 wouldn't fly due to new flight design changes.

>>11165965
there shouldn't be developement problems with anything but actually complex systems (engines, guidance, structural integrity during reentry). Building a rocket out of ridiculously thick steel is far easier than the intricate structures of all other launch vehicles.

>/sfg/ two days ago: it's okay, we expect some failures, starship is a "fail fast and iterate" development program, that's why they're building so many so cheaply
>/sfg/ now: wtf the "fail fast" program had a failure I hate agile now

>>11165965
>I'm becoming more and more concerned that this whole 'cheap and fast' method of development isn't going to work out.

There’s a difference between the ‘cheap and fast’ mentality which successfully lead to the Falcon 9 and whatever is going on with the exploding grain silos their building now. The original Falcon 9 (V1.0) was built ‘cheap and fast’ but still looked like this (pic-related). Even the shoe-string budget Falcon 1 looks positively refined to what SpaceX are building now.

>>11165924
Guess they failed NNN.

>>11165968
isn't densification achieved by chilling propellant/oxidizer? Liquids are not compressible

>>11165980
Almost like there's multiple people with multiple opinions here or something.

>>11165968
>back channels
look we're still in the middle of the fucking anomaly investigation here, anybody who tells you they're 100% sure is bullshitting you

>>11165980
I don’t think people would care as much if the Mk1 had failed in flight during the 20km hop, or even a static fire. But it failed before it even came in contact with a single drop of rocket fuel or oxidiser. It ended up as just a failed nitrogen container, about as far away from a spacecraft as possible...

>>11165995
Reminder that no Raptor rockets were harmed in the explosion.

>>11165924
>american space program
хaхaхaхaхaхaхaхa

>>11165983
Exactly. One defense of the starship development method I have heard consists of referencing how previous SpaceX vehicles were also developed 'cheap and fast.' The truth is that F9 was built in the same "oldspace-y" clean room, high spec conditions that all other spacecraft to date have been developed in. Starship is a completely different beast.

>>11165995
A 2x pressure proof test, if that's what they actually tested to, seems like a pretty acceptable way to fail. The carbon tank only managed 1.3x pressure.

>>11165995
Well there's a lot of conflicting stories flying about. 1 being that they recently decided MK1 wouldn't be flying after all and they filled it to failure to test the structure.

Given they are taking a rapid prototyping approach to starship, I would expect lots of failures like this to follow.

>>11165997
True, you’ve reminded me that anybody on NSF L2 can tell you that SpaceX definitely planned to fly Mk1, or at least static fire it; as they were planning to deliver it’s three Raptors at the end of November. This most likely wasn’t a planned destruction test and if it was they abruptly made the decision to destroy it only days go.

Until some math fag estimates the pressure you can safely go with the sniper rumors.

>>11166009
*ago

>>11166011
Nobody is claiming anything about snipers, there’s photos of how the Mk1 came apart and they show a relatively clean rupture down the circumference of a weld that connects the upper bulkhead section. Completely wrong shape to be a bullet impact...

>>11166011
The ULA sniper thing is just a joke.

>>11166016
Obviously ULA contacted the DOD for their top secret 9m diameter hula-hoop bullets.

In other news...two other spacecraft are currently on the move (in one piece), in preparation for future launches.

>>11166021

>>11166009
told you all last thread. we were planning on flying it, with no expectation of a successful landing. plan changed two days ago, told to descope mk1/2 and focus on mk3. still wanted to do a proof test (welp) and static fire (guess that isn't happening), then take off any parts that made sense to take off (so uh nothing from that forward dome, that's for sure, don't think the IMU box is flightworthy after that)

>>11165968
So it wasnt intentional.
Makes you think huh.>>11165931

>>11165990
Everything's compressible at high enough pressures.

>>11165924
>contaminating the air with all that nitrogen gas
SpaceX should be shut down by the EPA. Just goes to show that the public should be putting their faith in more eco-friendly, safe and mature hydrazine solutions like that found in the masterworks of time-tested contractors like Boeing and the ULA. I wouldn't want an irresponsible company like SpaceX spewing deadly nitrogen vapors into the same air our children breathe. I hope that handsome Alabama Senator pulls the plug on this disgusting sham of a company.

>>11166042

ULA have only operated one rocket using hypergolic fuels, the extremely reliable and long-lived Delta 2 which had the Delta-K hypergolic upper-stage; furthermore, Boeing are infamous for their obsession with hydrolox, the cleanest fuel in existence. Maybe your thinking of the Chinese or Russians who have an abundance of hypergolic launchers? Also, what’s wrong with spicy devil juice? The best family of launch vehicles to ever exist used primarily hypergolic propellants...

>>11166071

either way, I doubt they had proper shielding gas on the heat effected spot on the backside of the welds, and the wind and general ricketyness of the manlifts would fuck anybody up

No, it lost it's bulge during one of the revisions. Block 5 isn't like that.

>>11166090
No, that was just the first version of the F9 which flew 5 times. All later versions used the current “Octaweb” pattern (pic-related).

>>11166092
That is Orion, going to Plum Brook for testing.

>>11166094
>>11166099
>>11166101
oh nice, the octoring is probably a better design

>>11166104
Probably yes. But the grid was probably easier to build. Would certainly seem SpaceX like to build the cheapest possible rocket that works first, and then slowly improve with new builds.

I assume that Mk2 is being built by Puerto Ricans and not Mexicans, because it’s being built in Florida. But this is all besides the point now, because according to multiple sources Mk2 is getting scrapped as well, so it’ll never be launched.

>>11166011
>estimate pressure
What for?

testing pressures knowing it might fail =/= intending it to fail

>>11165924
lmao it popped like a monster can

>>11166175
So we know if it failed below nominal tank pressure, above it, or way above it.

That will tell us a lot about how the structure and its manufacturing holds up to reality.

If welds failed below nominal (as the lack of venting may imply) then beaners on forklifts welding rockets on salty beaches aren't an option.

>>11166180
Well on the plus side, now they know the failure limit.

I feel like if the pressure was significantly above operational (3atm?) Elon would be bragging about Starship's durability

>>11166024
Why's everyone skipping over mk2?

What's wrong with development in Florida?

>>11166191
I mean these tests are always done with above typical pressure levels, to reflect a worst-case scenario situation. How high the pressure for this test was, is unknown.

>>11165975
They are not just building a rocket, they are building it while trying to minimize build costs and time. So there are bound to be failures even of basic structure.

>>11166181
still waiting for the shops, get to work faggots

>>11166192
Puerto Rican intellectuals apparently...

>>11166185
yeah, need to build a windbreak for the salty beaners working the welding machines

>>11166196
welding together 3/16th inch thick steel is a bog standard process in industry, there are tens of thousands of people who spend their entire workdays doing just that. So is ultrasonic and xray inspection of said welds. Malnourished soviet kulaks eventually could be taught to do a decent enough job at it in roofless, freezing factories almost 80 years ago. There is no innovation to be had here, it's well established technology. Stainless steel pressure vessels have been the backbone for our chemical industry for more than half a century. And if you need an analogy from the space industry, the atlas centaur was using paper thin stainless steel tanks (that needed to be kept pressurized in order to prevent collapse).
There are many areas where starship could rightfully fail because it is pushing boundaries and leaving the area of tried and tested technology. Manufacturing the tanks isn't one of them.

>>11166185
Just estimate the weight of the upper hemisphere, determine how much force would be needed to blow it that high into the air, then divide that force by a ballpark of its surface area and you should have a good idea of the pressure that it popped at.

>>11166224
basically they tried to skip too much and rushed it and fucked it up imo

>>11166224
SpaceX need to try to poach some ULA employees if they want to learn how to make stainless steel tanks well:

>“Common Centaur is built around stainless steel pressure stabilized propellant tanks with 0.020 inch thick walls that can nevertheless lift payloads of up to 19,000 kg. A common bulkhead consisting of two stainless steel skins separated by a fiberglass honeycomb is located between the LOX and LH2 tanks, further reducing the tank mass. Heat transfer between the extremely cold LH2 and relatively warm LOX is reduced by the fiberglass honeycomb insulating layer.“

>>11166233
manufacturing of those tanks should be relatively different because starship needs a far thicker skin to survive reentry. They could just draw expertise from the (petro)chemical industry suppliers that have been providing fractionating columns and other pressure bearing vessels from stainless for decades while very rarely going full bhopal. Or from whoever has been building the vacuum vessels for various research applications.

>>11166228
maybe they thought they could get away without rigs that allow for proper shielding while welding and inspection systems for the welds, at least for the early prototypes. this may have appeared as a reasonable risk since the tank walls are really fucking thick compared to the tankpressure they will have to bear.

>>11166233
>pressure stabilized
Into the trash it goes.

>>11166252
>ULA can build tanks from .5 mm thin stainless steel
>whoever spacex hired to construct the prototypes can't build something capable of sustaining less pressure from 5 mm steel plates heavy enough for elon musk to bludgeon his manservant to death with after the test failure

>>11166258
>servants
Thralls.

Why exactly is SpaceX still fucking around with building the Starship like this anyway?

I thought they already had the mandrel needed to make the single seam rings. They could build a jig inside one of their tents or buildings to support horizontal assembly. The rings come off the mandrel, get put onto the jig which can roll the hull both in a circle and out the building. A stir welder could be set up to weld the new sections onto the rest of it.The stir welder wouldn't have to move the whole diameter, it could just do a small section before they roll the hull and reset it.

>>11166273
>diameter
Fuck, I meant circumference. Like this:
https://www.youtube.com/watch?v=aNbQH8XBgxQ

>>11166273
crane is cheaper than trying to keep the rings from sagging in the horizontal rig which also costs money
also stir welding is a meme for stainless, just use arc welding, it's better and faster and cheaper

Up..up...

>>11166287
Couldn't they just use a form on the inside to support the structure while it gets welded together and slide it inside to the next section while the finished sections roll out the door? There are thousand of ways to build something like this without lifting Mexicans 60 feet into the air so they can make welds. That may be cheap but it doesn't seem the most effective, especially if they're going to start mass producing these. I think it's a mistake if they try to build the next prototypes in the same way.

>>11166302
..and away!

>>11166302
Is that a real Starliner or a mockup for practice?

>>11166085
>except the first one
I wouldn't mind being bathed in dimethylhydrazine if my silo was this cool.

>>11166307

>>11166303
vertical construction in a shitty half-sided roofless building is probably the primo choice
weld the rings by hand in a shed-tent, and then run a welding machine around the outside to connect it to the one below inside a windbreak
cheap, simple, reliable (if you get the welding machine working correctly, which they never do)

>>11166307
That’s the real Starliner for the uncrewed test flight.

>>11166308
That’s the problem, the first one committed the sin of using kerosene for fuel instead of hypergolics. Not only is that disgusting and an insult to the Titan name, but it also made the T1 a really shit ICBM that was phased out quickly for it’s infinitely superior younger brother.

I can't take it anymore! I'm breaking my No fap november and want to mentally masturbate! So if we were able to HASTOL starship, how much payload could we get to LEO? Also building a basic orbital launch tether requires only 4 starship loads.

The Super Guppy has got to be one of my favorite planes in spaceflight.

>>11166352
I bet that plane watches a lot of Rick and Morty

>>11166313
I don't know, I still think vertical assembly would be way slower just because you have to change the height of the machines/welders with each new ring and they constantly have to move their lifts to weld horizontally. What I wonder is if a ring is strong enough to stand on its side without deforming out of shape because then they wouldn't need much support in order to weld it. It would be like in this video, which I've seen posted before, only they would be able to roll it away from them to add a new section and their equipment can stay in place.

2:00 in this video:
https://www.youtube.com/watch?v=LKUqKDY8XXM
>>11166358
Wouldn't the points where they jack it up constantly have to change as it grows longer?

>>11166358
the ring welder works best with a consistent thing to hang off of, right?

>>11165915

>>11166379

Oh fuck. Starlink might make orbital tether impractical due to the tether having to maneuver too much. Need to run the numbers though. Fun fact: the tether doesn't give a damn about objects impacting it smaller than 3 meters. In fact you could design the tether so it could survive a direct hit by an iridium satellite. So basically tethers are chad AF. Source HASTOL phase II final report.

But Elon and multiple other sources have suggested their going to scrap Mk1/2 and move on to a more refined Mk3/4 design. Mk2 might possibly be used for fit checks at LC-39A but that’s it.

That no longer would be good marketing. Personally, I have some doubts it will be that good on Mars because of the size of xEMU suits that basically turn everyone into a 500 pound obese person and I'm not sure there will be that much room in the cab.

Elon has said the driver seat would fit somebody like Andre the giant (7ft 4, 500++ pounds). Will know if this is true in a couple of hours.

>>11166987
Pressurized cabin and suitports seem the solution to that

>>11167144
Right, I completely forgot about that. I hope they're not doing a single seat in the front of the truck like with the Tesla Semi, but I think that would be the only way you can comfortably fit someone like that.
>>11167191
I know that Elon Musk mentioned a pressurized model, but that could just be for talking your helmet off while inside the truck or for emergencies. I don't see a suitport being practical. The truck would have to dock to a habitation module or they would have to get into their suit and walk to the truck just to get out of it again.

Realistically, how much driving are they going to do on Mars in the first few years? I feel like the new Martians would get in and out of it far too often to warrant the benefits of a suitport unless they're exploring long distances.

Honestly, that truck is cool as fuck. I was terrified at first but it beats the fuck out of an F-150.

>>11167356
Here's the back of it.

>>11167359
Inside

I won't post all the photos. You can see them here:
https://www.tesla.com/cybertruck

>>11167366
It looks way too edgy. Like it's trying too hard to look futuristic.

>>11167370
It's really only edgy because of the outdated design of other trucks, but the design itself seems to be pretty functional.

>>11167356
Agreed, but I don't think it can be competitive. I'm not a truck expert, but at that price point (even considering gas savings) and probably lacking some standard latent features, it's not competing with lower-end pickups. With all the F-150 comparisons, I don't think this is supposed to be high-end either. It just doesn't feel utilitarian, and regular pickup buyers will probably agree.

>>11167377
I think the sharp corners are suboptimal but probably easier than bending that stainless lol

>>11167377
>It's really only edgy because of the outdated design of other trucks
Outdated how?

>>11167226
In the nat geo Mars tv show the Mars colonists rocket lands too far from hab due to equipment failure. In that case they had to use a vehicle to get to the hab.

>>11167377
Not him but personally it's just a bit too angular for me, smooth out just a few of those lines around the tire wells, add a bit of a break flatten out that harsh slope between the top of the cab and the bed and cut out a bit of the unbroken angle of the bed to make it more visible and it would look pretty damn great actually. The other problem I see is that the inside is practically barren, I don't even see a dash display at all, or forward cupholders, phone or tablet chargers, or even AC apertures. Granted this is a display vehicle and may not be completely done, but still if it doesn't have those kinds of things I can't imagine anyone wanting to buy it.

>>11167380
It's way cheaper than anything comparable to this. Most trucks actually sell for much more than the starting price. It's faster than some Porsche 911s, and the body is literally bullet proof against 9mm. It has a retractable panel for the back which is a huge deal because no one wants to leave their tools or gear exposed to the elements. That's actually the reason why I never bought a truck and prefer wagons.
>>11167386
The structure has been resigned from the standard body-on-frame truck, which is why the body panels look so strange. Body-on-frames likely won't work that well in electric trucks, but we'll have to wait for further testing to compare with.

look I'm a huge Elon fanboy but this truck is the ugliest fucking vehicle I've ever seen in my life

it looks like an 80s parody of what 2020 will look like

is that the joke? am I being trolled?

I don't know much about automobile engineering, so I'll buy the body differences explanation for now. Still looks ugly as sin.

>>11167438
Why would you possibly think that? You can hate the design, that's fair, but it's unreasonable to think that this doesn't out perform nearly every pickup on the market and include features that they simply don't have, like a air compressor and standard ramp for the tailgate.

the air compressor sounds nice actually

>>11167450

>>11167450

On second thought, let me redact some of that. It's towing capacity appears to be worse than some competitors. We'll have to see if it improves because sometimes Tesla lowballs their specs before greatly improving them once they start production.

Idiots who make whatever up to prove their point are much worse than any super fan. You're encouraging people to talk about him more because they will want to correct you.

"He left in 1992 to study business and physics at the University of Pennsylvania; he graduated with an undergraduate degree in economics and stayed for a second bachelor's degree in physics. After leaving Penn, Musk headed to Stanford University in California to pursue a PhD in energy physics." Instead of doing a PhD, he dropped out to start a business.

Mech undergrad who just finished solid mechanics here. Why did Starship fail in axial stress when hoop stress is higher? Why didn’t it tear a rip vertically (like how they run the range safety det cords)?

>>11168365
Because it wasn't a perfect sphe... um, cylinder of uniform density? The welds are weak points of variably unknown strength.

>>11168292
Those new suits can't go into service fast enough, you can see how hard the current suits make everything.

>>11168365
Watch it frame by frame, looks like the dents were slightly contracting it longitudinaly and when the pressure pushed them out it grew ~6" is a hurry. My best guess is the momentium of that tank end was high enough after the expansion that it put huge tension loads on skin leading it to tear horizontally (also visible for 1 frame).
t. not an engineer but a guy that watched it alot.

>>11168378
aren't the new suits for walking on terrain?

>>11168407
I believe they will be multi-purpose or at least there will be a separate Zero-G version. It was mentioned they (the new suits) would be tested first on the ISS in 2023, before heading to the Moon.

>>11168415
maybe just me but even the new suits didn't look super comfortable. You could see in the presentation that the woman demoing it found it very hard to bend down and pick up something.

>>11168365
Because the hull isn't one continuous piece of metal. Looks like a weld failed.

>>11168419
>You could see in the presentation that the woman demoing it found it very hard to bend down and pick up something.

That’s because the suits are really heavy, the version they demoed was heavily stripped down, you wouldn’t be able to move in actual EVA suits on Earth.

EVA suits are also ridiculously inflexible, to the point that even being able to significantly bend over is a massive upgrade which xEMU has over previous suits.

They use a robotic welder that friction stir welds the panels together.
They actually invented a new type of friction-stir welding for this, which is why they didn't realize a small change in the welding pin design back in 2017 would screw up the tanks. They ended up having to build new replacements with the old pin, which caused about a year's delay for the first core stage.

Look, reusability doesn't make sense to a government-backed tankage company for one good reason—jobs. Let us say we had ten guaranteed fills per year and we had a tank which we can use ten times—we would build exactly one tank per year. That makes no sense. You cannot tell those welding teams: 'Goodbye, see you next year!'

>>11169170
Anyone who thinks this is a meme doesn't understand manufacturing.
This is why reusability has to be coupled with a high flight rate. Otherwise whatever gains you're making on the recovery and refurbishment side are getting eaten by the loss of economies of scale on the production side.

JUST DO ALL THE EXTRA MISSIONS THAT REUSABILITY ENABLES FFS

>>11169288
TBF, in the context of the original quote of Ariane saying that they can't do reusability, their primary customer is the EU government. If the government doesn't have a launch ready, then Ariane doesn't launch and the rate of government payloads isn't high enough to make reusability practical.

>>11167421
I can't decide whether they're goading every other manufacturer into making a horrific angular abortion, after which they release the final Cybertruck design - which is Citroen DS level elegance, or whether they're actually serious. Either way fair dos

>>11169310
It's just utter madness though isn't it? If it's all about funnelling money for job creation let ESA just do reusability and redeploy some of the lost fucking rocket manufacturing jobs to building payloads. The money can keep flowing and the jobs can stay. Same budget, more space stuff accomplished, plusieurs boisson fortes all round.

>>11169325
ESA don’t actually build rockets, Arianespace, a private (but heavily subsidised) multi-national consortium who’s biggest stakeholder is Airbus do. It’s actually quite a genius system for winning commercial launches, as Airbus builds a lot of satellites and it’s not hard to guess who they advise their customers launch with...

>>11169325
To play devils advocate, just switching the entire launch production to reusability and then relocating displaced workers to make more payloads isn't a simple change. Firstly, a rocket production engineer might necessarily not have the same skills required to be a good payload production engineer. You can't just change his job all of a sudden (apart from him liking his old job and might not like the new one) without needing to retraining him and when there are thousands of employees this can get very time consuming and expensive very quickly. Secondly, while governments tend to be the most wealthy institutions in the nation, they still have finite funds. There might not be enough money to make more payloads to fulfill the needs of a reusable launch system (even with the cost cuts of reusable launch vehicles). Thirdly, there isn't a strong and fast interest in developing more payloads (at least with the government), they are perfectly happy to take their time developing their payloads which results in a lower volume of production necessary to make reusability practical. For example (albeit not European), JWST is infamous for taking a long time to develop, but there aren't any calls within the government to push the development along. It's not a scandal that JWST is taking so long, at worst there's just frustration.

Reusable launchers are the way to of the future, but current markets and mentality "traps" the industry to expendable launchers. In order to develop reusable rockets, a massive hit in potential production and profits needs to be taken and that's something most governments aren't willing to do.

>>11169376

>>11168978
>beaner employment is cheap
Who woulda thought?

>>11169170
Instead of having hundreds of seperate contractors dependant on their product being thrown away you fold them into a single nationalized company buying each company out at 110% stock market value.
If only the US could do this they could save a fortune on government contracts but we all know it couldn't be done because of political corruption and latent public fears after decades of anti-USSR propaganda.

Apart from methane and hydrogen, what are some viable alternatives to using kerosene as a high energy rocket fuel? Hydrocarbons specifically.

>>11169696
Why would you want to use anything else?

>>11169696
in the 50s and 60s rocket propellant research went (among other things of course) through pretty much anything you could reasonably (or unreasonably) think of as a fuel candidate. On the side of organics that included every amine/imine/mercaptane you could think of, shove some boron in there for good measure as well. In the end nothing ever came of it. RP-1, methane and hydrogen are your best choices. All are scalable and you have to make the decision between specific impulse and ISP.
They found other promising oxidizers but those are all hideously unstable and reactive, so oxygen it is.

>>11169710
Looking for something that's liquid at standard conditions but doesn't have the coking problems of kerosene.

>>11169716
Thanks.

>>11169721
Ethanol maybe?

>>11169742
significantly worse specific impulse than RP-1. If you want less coking problems you want more hydrogen, if you don't want to loose performance you don't want partially burnt fuel. Hence (among other things) the move to methane.

>>11169721
if you're interested in what fuel research was like read ignition by john d clark, it's got most of the exotic crap they tested covered. The short story is that they found some fuel/oxidizer combinations that looked promising but are expensive and god awful to handle. In terms of reusable engines with short overhaul times boranes and fluoride based oxidators would most likely be much more of a problem than a bit of coking from methane too.

>>11169696

Are you looking at making your own engine? If so alcohol / nitrous oxide is the best option for amateurs due to clean burn, non-cryo, non-toxic. ISP is far from the best but unless you have a few grand to spend it's the best you will get.

I've added that to my wishlist, gonna ask my family for it since they haven't gotten me my birthday present for this year yet.

>Are you looking at making your own engine?
At least designing one, yeah.

>alcohol / nitrous oxide
I've considered that, and it is one of the propellants I'm considering (specifically methanol). However, I'm considering to have the engine be film-cooled (might abandon it because it seems like there's no good way to model it without resorting to CFD, and RPA is mad at me) which means that the engine would have to burn very fuel rich. This will result in a drop in performance and alcohol/nitrous is already relatively low performing. However, hydrocarbon fuels offer much better performance, even at very fuel-rich mixtures they beat alcohol at optimum mixtures. So an engine that even uses "aggressive" film cooling with hydrocarbon fuels can retain a fair level of capability.

>cant figure out a solid business plan for the moon
How would /sfg/ turn a profit on the Moon? I'd send landers that act as base stations providing power, navigation, and communications to other companies rovers. Infrastructure is $$$.

Mine water, electrolyse, sell fuel and oxygen.

>I'd send landers that act as base stations providing power, navigation, and communications to other companies rovers.
That's a pretty clever idea. And you can make the landers modular so they can be easily broken down into their components by either a person or a rover with arms so that the parts can be used for other things.

For effective film cooling do you need a higher vapor pressure to slow evaporation?

>>11169857
Radio telescope on the far side on the moon, no interference from earth and can be build HUGE thanks to low gravity.

>For effective film cooling do you need a higher vapor pressure to slow evaporation?
I think a high heat capacity and boiling temperature would be more favorable.

>>11169857
Swarms of little surveyor robots. They'd probably be flea-hoppers with long whiskers/legs to keep them off the regolith. They'd have redundant sensors such that every landing orientation would have full observation ability. Cellphone cameras, basic spectrometers, with a gravimeter and Geiger counter inside.

The goal would be to gather tons of high-fidelity visual and mineralogical data, sell it to prospective mining companies, and keep the juiciest data (like pockets of near-surface radioactive material) to myself, or auction it to national interests.

I only leak SpaceX info to 4channel, I don't even do the L2 thing

that dome had a perfectly reasonable 2.1bar of pressure behind it and a vertical weld gave out and then that led to the circumferential weld giving out

the cape build is getting mothballed because Elon is sick of flying back and forth between the two sites, all focus is going to boca. again this decision was made monday

and we were like halfway done building a starship launch pad on the side of 39A

still tho this is probably the fastest way forward, I'm still excited

also today's froyo flavors were toasted marshmallow and graham cracker

lol fukc journalists though

Ignition? You know that you can download a PDF of it, right?

>>11170117
Thank you for your service

>>11170121
Picking between having good specific impulse or having a good internet service provider is a tough decision to make.

>>11170124
Really? Where?

I'm honestly surprised by how easy it was to get. I expected worse. Thanks!

aww you know it
and remember you're here forever

>>11169213
also, just a heads up, if this shit happens again I'm done posting here

don't be a fucking redditor

>>11170186
Based, fuck Reddit and absolutely gas crossposters.

Sounds legit.

ISP and density. I shouldn't write shit while dead tired on my way home

>>11169192
the best part about shitty welders (or even good ones) is that they can work on more than one project
it's just that every January and February they get to make a rocket instead of a water tower or boat or whatever

>>11169716
it's not only RP-1 and Methane, it's all hydrocarbons
petroleum jelly and LOx only works in hybrid motors but whatever
>>11169721
propane or butane would work great for maximum combination with HTP
