Possible. But not politically feasible.

Yes, at least IMO

Guys I’ve never launched a rocket before but I have these plans that, in 2025, I’ll be doing 600 launches a year, if only I have your financial support

Retarded and wasteful. Directly interferes with global temperatures, to boot.

>>12795684
Any evidence to back that up?

>>12795696
It's rockets anon, you can't just add mass.

Does anyone have a good resource on expected temperatures at various depths in the lunar crust/mantle?
Trying to figure out how deep you can go and still have a habitable temperature without the need for cooling.

>>12795696
If only they had a SUPERIOR isogrid to give it structural support

Possible, but retarded because of inefficiency

>>12795717
Damn good question. I gotta go to bed, but maybe this will help you assuming you haven't taken this step yet: try googling "lunar geotherm" or "moon geotherm". There's probably data from apollo experiments somewhere that will show temperature vs. depth. Or at least the heat flux or something

>>12795752
>moon
>geo
We really need to unfuck our terminology.

>>12795743
muh global temperatures is why we care about solar in the first place instead of going even more ham on oil

>>12795727
This was from the explosion and also a joke

>>12795757
What explosion

>>12795754
Meh, I know it’s dumb but the phrase geology came about before the concept of trying to study other planets. Plus if every planet got its own name it would be too pretentious (like astronaut, cosmonaut, tychonaut, etc.). Lunography sounds pretentious—but even MORE pretentious is the fact that assholes at NASA unironically call it “selenography”
>>12795717
Okay fucked around and found this. It’s in kelvin though, so sorry

>>12795696
maybe if they used glass instead

>>12795770
why does the temperature go up?

>>12795770
Could you find a martian geotherm as well?

>>12795780
The horizontal measure is depth, the Moon might be frigid on the surface but it's core is still going to be warm.

>>12795770
*lunology. My argument still stands though and it sounds gay
Also what are the most interesting ROCKY moons of the solar system: hard mode being no Titan, no ocean worlds, etc. I know next to nothing about all the other solar system bodies other than they look like the Moon. I’m sure they are compositionally way different though. Io is based. Triton is pretty.

>>12795780
Same reason it gets hot when you go into a mine on Earth. All the overburden rock creates heat and pressure

>>12795787
Forgot pic SHEEEEIT. We really need an icy giant orbiter mission. The moons of youranus and neptune need to be explored

>>12795770
Lunar geotherm got me this:

Which referenced:
sci-hub.se/10.1029/gl009i001p00037
Which was a neat resource. Seems to get hot surprisingly fast, which is a little disappointing.

How could they predict the moon

>>12795787
there aren't many rocky moons of the solar system other then io and the moon

>>12795810
where does this elon died meme come from? he has spoken on twitter AFTER people claimed he died.

>>12795754
Lunology sounds fucking gay. There is nothing wrong with geology.

>>12795712
yes

>>12795814
Youre trippin, there’s a ton. I guess there are a lot of “icy” ones, but they aren’t ocean worlds. Callisto, Titania, Rhea, Oberon, Iapetus, just to name a few
>>12795781
I can’t find it but I might be able to get one tomorrow morning if no one has replied to you by then

>>12795822
Show me some your evidence then.

*farts on you*

>>12795822

>>12795755
Who said I care about solar? You might, but it’s obviously worthless shit for earth use. Only good for outer space

Nuclear all the way fuck pissant solar

>>12795816
Maybe that’s not him

>>12795704
BN1 will probably wait until the tower is built. Also its relatively easy development wise and a lot of the starship testing applies to it directly so we will probably see quite a few more starship flights before it.

>>12795823
>Callisto, Titania, Rhea, Oberon, Iapetus, just to name a few
Callisto has a very good chance of having a subsurface ocean, its just really fucking deep under the ice, around 155+ miles down. The ocean is believed to be salty and interacting with rock though, so good chance with life. In fact, all the galilean moons of jupiter except io are believed to have subsurface ocean.
Regarding Uranus' moons and saturn's moons, they might have subsurface oceans, we just haven't done a detailed enough study on them to prove it

>>12795841
why do you think he died without any evidence?

0 IQ question, but why is geothermal power restricted to places on Earth where the heat flow is extremely high (i.e. places where intrusions have heated up the ground)? Why can't we go anywhere on Earth and just dig till we hit 100°C, drop water down there, and use the steam to run turbines above it

https://www.cnbc.com/2021/03/04/dangers-await-humans-on-mars-as-elon-musk-eyes-colonization.html
>Stirone told CNBC’s “The News with Shepard Smith,” that the human desire to go to the red planet stems from culture and science fiction, but Musk’s motive is fundamentally driven by a “colonialistic view.”

“The difference with him [Musk] is it’s not driven by a scientific motive for discovery and search for truth, instead it’s a colonizing, imperialistic, property-value, dominating, factor, which I think is terrible.”

/sfg/ - Whining about every post that isn't 100% on-topic general

SpaceX would be so much better off if they bought some nice farm land in Arkansas with a direct water connection to the gulf

They would have tons of room for hops, separate test stations, tons of big tents, no dust, no hurricanes, No salt coming off the ocean, can’t dig down rather than build up, etc

They have to literally truck in soil to build up the area around Boca Chica if they want to build there... and they are surrounded by public lands

That’s why they bought barges

Damn I was taking a hail mary hoping I would be right. Wanted to get under your skin lmao

>>12795887
And by barges I mean oil rigs

Pretty crazy to think that we might see high altitude (above the karman line possibly) hops with SN15 by late april/may.
>>12795887
>Neither will Boca Chica lol
Yes it will be, why do you think they are building an orbital launch pad? Barges just allow them to increase the launch cadence greatly, doesn't mean they can't launch from boca chica (and they plan to).

>>12795887
Bro unless you plan on the Mississippi completely wiping Louisiana off the map in the next 5 years, Arkansas won't even be the backup plan to the backup plan to the possible backup plan for another launch site or build facility

They build in Arkansas, then ship the rockets down the Mississippi, then along the coast to wherever the oil rigs will be set up for launching

I wonder when the first actual war will include a space theatre that is beyond satellites zapping each other. I'm guessing 2050+, because there needs to be a large economy in space before a country can justify building actual warships, and even longer so before those warships are ever used.

>>12795897
yeah, that does look nice. I'd like to see more rockets with nice designs on them. The Vulcan would look pretty terrible without it.

Interesting. What do you guys think? Perhaps related to the odd fire that appeared after relight?

>>12795940
>light mode twitter

>>12795940
The odd fire was literally just methane that caught on fire from a tiny leak, what elon talks about in that tweet was probably a software issue I'm guessing.

Not sure why they went to single engine landing either

>>12795947
>literal who on Twitter not even about spaceflight

>>12795944
Yeah I take this as meaning "we ran a bunch of simulations, and even the computer during the landing was telling us a discrepancy between expected velocity and actual velocity"
Brings me back to that reddit post some anon shared a day or two ago where Elon mentioned the autism of running his simulations pretty much every night, and they still found stuff during flights that made them pull even more all nighters to solve everything

>>12795947

>>12795944

>>12795952
he works at JPL. In my experience it seems like in exchange for knowledge on a single topic PhDs become absolute dumbfucks in most others.

>>12795947
God dammit, I thought this guy was okay

>>12795952
He wrote several pieces about SLS that apparently got NASA attention. The idea of someone who works with rockets demanding a gun ban makes my head hurt.

>>12795965
>>12795968
see
>>12795962
but yeah he's a europoor immigrant, so it explains why he would not be opposed to america's gun culture unlike the people who have had families in america for 300-400 years.

>>12795977
That's why all immigration needs to be ended for the next century.

>>12795964
I have a burner twitter account. It’s mostly just for taking screenshots of foust and berger and whatnot for here (there’s probably like 2 or 3 of us here on /sfg/ who go with dark mode and actually post the good stuff from there). Feel free to stay away from it but it is completely possible to not link anything and stay anonymous, and there is some funny shit I see every day because I know who to follow. Also I use it to purposefully look at all the SJW shit and intentionally boil my blood. Idk how to explain this part, it’s like going on reddit but on steroids. It’s literally like peering into the twilight zone of progressive chimpanzees who were given access to a technology they cannot handle. They are always trying to out-virtue signal eachother. Despite it being made fun of across 4chan I recommend it overall. I peruse use everyday and for context I haven’t touched reddit in probably 10 years now so you know it has to be way more redeemable

>>12795987
Holy shit I didn’t mean to write that much. That was stream of consciousness autism typing.

>>12795940
Hmmm, from my limited understanding here there's several computers at play in this system all at once, each raptor has it's own computer and they're all talking with an avionics computer which is also talking with sensors reporting back velocity, distance from ground, etc.
Could just be some kind of disagreement with the Raptor comp and the flight comp, maybe they need to give the flight comp a little more authority/stronger priority value so it can overrule the engine comps more aggressively. It's all a balancing act to find out where that sweet spot of synergy is between all of the parts.
I wonder if you could use learning AI for these kinds of things and do a shitton of training based on the existing real flight data. Have all of the raptors and flight computers training for thousands of cycles while they sit in the warehouse waiting to be installed on a real ship.

glad they're putting this in. Really need quick backup engine relight capability during landing.
It wouldn't surprise me at all to see these engines become more landing-specialized over time while the others become more thrust-oriented. For landing engines even sacrificing power to get lower throttle would be worth.

Well countries all over the world have people on all sides of the spectrum. But by and large, outspoken academics in the western world tend to be left wing. And recently they have shifted more and more left. Plus most countries tend to be more left wing than the United States as a whole. The whole thing is stupid idk how to reconcile it with myself other than by coping

>>12796040
I do not give a single fuck about how many people Spacex is employing.
The second we start caring about how many people a program employs is the second where we justify SLS as a jobs program.

>>12796049
> Plus most countries tend to be more left wing than the United States as a whole.
Most US satellite states in western europe? Yeah, but not other countries.
>But by and large, outspoken academics in the western world tend to be left wing. And recently they have shifted more and more left.
Sadly, yes.

>>12796049
The primary role of universities has always been to publish propaganda. That they produce anything actually valuable in the side is a blessing.

>>12795721
You mean that hyperretarded expensive oldspace wtf even is machinetime stuff that is basically the definition of why oldspace failing, even on government lifesupport?

rip

>>12796053
Oh I’ve always been told that the US is way more conservative than countries like Canada or the UK and whatnot. Like on a political spectrum even our left wing party is more conservative than other left wing parties. Idk I’m not an expert though. And recently it seems with the internet, all political ideologies across the western world are converging and becoming uber retarded on an equal level.
Oh- and something something spaceflight so I don’t make everyone too mad

>>12796051
caring about jobs numbers isn't inherently bad
Spacex cares about having too many jobs since it isn't government funded but it leveraging its jobs numbers to the local government doesn't make it SLS

thanks to our fellow redditors we now know what square sn10 landed in

>>12796069
What's SpaceX's take on protecting intellectual property? Is there any secret special sauce in the raptor engines? They are extremely transparent otherwise and I never thought about it really.
Could they auction off the junk to enthusiasts or gift it to museums?

It is, which is why I said its more conservative then its satellite states in western europe (and canada and New Zealand and Australia), but america is very left wing compared to eastern europe and other parts of the world. 13 years ago (2008) a democrat party member ran on a platform that included opposing gay marriage, nowadays if you oppose it half the republican party will call you a nazi. Thank gosh there has been recent resistance to this shot.

Most of the important ITAR information is shit like internals of turbo pumps, alloys, and software.

>>12796104
whoops
Green- SN8
Blue- SN9
Purple- SN10

>>12796091
Elon seems to think that recreating raptor from internet pictures is basically impossible. I myself am extremely skeptical of that claim, you might not get a 1:1 perfect replica and internals such as injectors and turbopumps will still need development but you can sure as fuck work out a hell of a lot of information with the right group of analysts.

>>12796112
elon probably wants others to copy him. but in tesla's case nobody has managed to hit the same efficiencies despite having the cars in hand and tearing them apart. it's not easy apparently

>>12796112
> you might not get a 1:1 perfect replica and internals such as injectors and turbopumps will still need development but you can sure as fuck work out a hell of a lot of information with the right group of analysts.
turbopumps, alloys, and software are 90% of the difficulty of developing the engine

the fact that starship didn't fall over even with its landing legs getting crushed and it bouncing, makes me think that worries about it tipping over on the moon for HLS aren't really warranted

>>12796127
Bros..... He's deflecting...

Imagine if they nosed down the landing site so it didn’t get covered in dust

>>12796142
Hosed*

>>12796131
I think he means that even if all six legs deployed, it would have crushed them; the loads were way over design spec.

Sorry, I'm new to this general, but has the idea of gravity trains on the moon been done to death yet?

>>12796142
>Imagine if they nosed down the landing site so it didn’t get covered in dust
Great, now I'm imagining the MoonJew 6000000 snorting up all the regolith in the LZ into a giant nose.

>>12796112
>>12796123
so they wouldn't auction them off the private collectors or give them to museums...

>>12796151
You mean like a full circumference mass driver, or a hab on tracks providing full G? Probably more useful on Mars than the moon since Earth is never more than three days away from the moon's surface.

>>12796051
SLS is associated with jobs in the sense that congressmen like jobs because jobs = voters

in this instance being interested about the number of SpaceX personnel at the site has no "slippery slope" connection towards "we need to keep Starship cus muh jerbs"

>>12796126
why hasnt china replicated it? they have the factory too now

>>12795686
Yes but RP-1 is best KSP by far.

>>12796112
The Chinese were able to steal a solid chunk of the F-35 schematics off of a contractor server. They had a lot of gaps missing but they were able to fill it in with their own Chink designs (presumably they just made a frankenstein hybrid of the American schematic with soviet filler). On a similar note Elon probably doesn't care if others try to copy. As long as he does his best to follow ITAR, anyone who copies will never have a true Raptor without 100% Raptor schematics.

>>12796091
ITAR cares about the software more than anything else, I wonder if they would care about photos of the turbo pumps getting out as that is really the heart of rocket engines.

>>12796164
No, I'm talking about transportation to different parts of the same planet.
The idea is that (if there was no friction), you could dig a tunnel connecting any two points of a sphere, let gravity pull a train through that tunnel, and the train would arrive on the other side with just enough energy to make it and no more. Also, every possible tunnel would take the same exact amount of time. For a sphere the size of Earth, that time is about 42 minutes.
Some problems with doing making a system like that on Earth is that:
1.) the earth has an atmosphere, so there would be a sizable amount of friction
and 2.) It has a liquid mantle that is hard to "dig" a tunnel through
The moon on the other hand suffers from these problems much less. Quite an efficient mode of transport.

>>12796199
Now that I'm thinking about it, I guess this doesn't really count as "spaceflight"

>>12796190
Ah man I love RP1/RSS but it was so damn glitchy. Plus all of the mods are awful to install because not all of them are up to date with RSS

>>12796121
Old manufacturers probably couldn't bear the embarrassment of not only having tried to postpone ev's with all they have, but now to copy the new kid. And now they struggle to keep up because they were to up their own asses to acknowledge the thread. Same reason why the Big 3 were so hesitant to just pickup what the Japanese were creaming them with in the 70's-90's and rather sandbagged them off with guilt tripping the US customer base or chicken tax. It's the definition of an industry standard.

>>12796199
The mantle is solid but still, liquid inner core. And no even on small bodies like the Moon you are never going to be able to dig through the whole thing. It’s just impossible. The temperatures and pressures are outside the parameters of even our best material science.

>>12796207
This is so off topic but a few months ago I stumbled upon Bezos’ website for his bootleg tesla company by mistake, and it made me snort out loud laughing. The website was an unapologetic ripoff of the tesla website, the “vibe” (if you will) of the site was complete söyboy granolahead hipsters camping in the wilderness with their ebig lectric truxks, and the cars themselves looked like fucking dogshit. The man is playing catch-up and it’s pathetically obvious.

>>12796218

>>12796112
ITAR is mostly to do with guidance software honestly, a shitty 70's rocket engine is more than sufficient to have a functional ICBM but it's rendered kinda useless if you can't at least put your warhead in the same postal code as it's intended target. SpaceX guidance is basically the gold standard at this point, it can put a rocket like Falcon, bigger than any modern ICBM onto a moving target with like +/-5m deviation from the ideal target point with 90%+ reliability.

Gahhh no you’re right. I cut it out for a few weeks for Lent (don’t judge pls) and it made me feel a lot better. But I gave in and all my Lent shit collapsed.

Bro I thought this was a space thread enough of this boring rock knowledge.

That aside, I wonder if that kind of system could ever be useful in any circumstances. I mean, the whole idea is reliant on the thing having gravity, so there's always gonna a lot of pressure in any case where it's applicable.
Guess it's just doomed to science fiction then.

Independently from /Sfg being the Elon fanclub and us all being unapologetic Elon shills, the man created a league for himself and other super rich people now try to best him because all of a sudden just owning the biggest and ugliest yacht isn't the defining factor for having the biggest peepee in the marina anymore.

What boggles my mind is that now everybody needs to best him in the same discipline instead of becoming their own persona. Like the only megaprojects you could do were, build battery cah and go to spamce. (or other comparable well threaten paths)

It's just another example that goes to show how unimaginative the super rich are, even these who dare to touch their money can't come up with individual thoughts.

>>12796265
What does that even mean? I fucking hate Bezos companies so fucking much

>>12796218

>>12796251
No judgement here, we all have our own mental structures for guiding our actions. So whatever works to help you is fine, all I can really say is that anger is good in small doses or in resppnse to something personal, but when its caused by something that doesn't actually affect you, you should always wonder who or what benefits by you being angery at said thing. Anger is a great motivator, the problem is that it can be used by others to motivate you to do say or think things you wouldnt otherwise. Causing anger is a great way to make people do stuff, try and wonder who benefits by making you angry in that moment. There is no free lunch, so its best to wonder why someone would want to give you a free dose of rage.

There is something to be said in criticism of the shitty kind of work environment that causes people to simply burn out, suffer stress and sleep and malnourishment induced psychological issues, and retire very prematurely because they can't mentally or physically handle 24/7 project crunch.
You're burning the candle at both ends with that kind of work environment and at least in my opinion you aren't actually utilizing your work force to the greatest benefit that way, they're super productive for a few months and then as burnout starts to kick in they get less and less so, start making simple mistakes, and at some point they can't work effectively at all and have to be replaced. Not an ideal use of talent.
Bozos doesn't have any fucking right to criticize anyone though, considering that his Chinese business partners use literal slave labor, his Indian business partners pay their workers a couple bucks a day, and his American and European workers have such shit work conditions that they are asked to sign NDAs preventing them from speaking about those conditions under threat of legal reprisal.

>>12796271
Hmmm. It’s pretty small. About 250 miles in diameter; a fraction of our Moon. But still pretty large. The deepest hole ever dug by humans was the soviet Kola Superdeep Borehole, maxing out at 7.6 miles before even the advanced equipment failed under the immense heat and pressure. But that is because Earth is huge. Mimas likely has much easier dynamics, plus it’s mantle is most likely an ice slush, with a dense rocky core.
I would say it could be POSSIBLE, but I wouldn’t be surprised if I looked more into it tomorrow and found out it would be impossible. I could calculate it but I need sleep first

>>12796281

>>12796284
Great points and realistic criticisms. Agree on the Bezos stuff, and that’s a really interesting lens into Musks’s companies. I knew about the burnout rates and all nighter memes but i’ve never considered the aspect of it possibly wasting talent because of the crunch. Thank you anon

Thank you. Your late night guidance has been helpful friend

>>12796284
in my experience in every company I worked for, it was the 20-somethings that worked the hardest before realizing that in mid-late career you can basically kick back and do fuck all while getting paid more. SpaceX knows how to put the most productive people to work. After they're burned out, they can go literally anywhere to for a cushy high paying aerospace gig.

>>12796293
Damn you raise a good point as well. Whatever the case (whether Musk is burning through talent, or running off the initial high that all young people have) I’m not going to deny that it has been working. At the end of the day it doesn’t matter if spacex could be X% more ahead if they had better working conditions, because the fact of the matter is they are light years ahead of anyone else

>>12796288

Musk is pushing so hard to get to mars before he dies or is too old to go.

>>12796285
>Mimas likely has much easier dynamics
True, maybe even an understatement, micro gravity means almost no structural concerns and an extremely easy disposal process of overburden and tailings, probably less dense material overall, no flooding, no heat problems.

125 miles to either end does sound like a challenge, but you could bridge the later steps with nuclear energy

>>12796300
That is true, I probably couldn't work productively under those kinds of conditions but in the end, so long as people go into it with eyes open, I'm not going to raise some kind of self-righteous ethical stink about it.
It's one thing if people are conned into working at a place they think will set a tough but reasonable pace but then it turns out they're literally working their employees into mental collapse, but completely another if the company says "yeah, we're busting ass to get this done here, it's gonna be 6-8 hour double shifts all the time with no let up, Mars ain't gonna wait".
In that case people have to figure out for themselves if they think they can handle it, and I wish them luck if they jump in.

>>12796311
i completed all japanese cultural boards and video games and now i visit interest boards. next week i go to humanities board! i will try to finish my undertale rocket oc soon

>>12796325
My only critique is that it’s hard to get into in the first place. Obviously Musk doesn’t want to waste his time accepting every fag with a resume, only for them to all waste his time and cry or try to sue him for work conditions or whatever. But I feel bad for people like our fellow anon who probably busted his ass, tried to apply, and then got turned down. I think a lot of it seems to be either great networking, or going to school in california or something. Or both.

>>12796344
That makes sense at the moment because SpaceX started up in Commiefornia and was (and still is to a moderately large degree) run like a silicon valley tech company. That will have to change at some point though, as they switch over from limited rocket production and (relatively compared to Starship) slow launch cadence of Falcon 9 to balls to the wall mass industrialization of Starship manufacturing and launching.
They already said they need to expand the Boca facility tenfold from the original 300 to 3000 just for a start, and I assume that will only just be the beginning. At some point there will have to be an institutional change in SpaceX company culture to adapt to the massive growth of the enterprise.

>>12796284
Who cares, though? It's one thing when it's retarded ESLs getting baited into crippling financial situations to be a pseudo taxi driver with somehow worse conditions. But the people at SpaceX know exactly what they're signing up for and do so willingly. I'm an engineering undergrad and if I didn't have a wife I'd love to bust my balls at SpaceX for a few years because it's the best chance at getting something I create into space. No other company offers that kind of opportunity. What's the alternative? Slave at NASA/JPL for a decade(s) and hope your project doesn't get canned and actually flies? Imagine dreaming of being a rocket scientist, finally getting your dream job at some contractor, only to watch all your work get molested by middle management and to wait decades for the SLS to blow up. But at least the benefits were good?

We suffer from the same problem as every western country, with the urbanites being the retards at the forefront of progressive ideology that has no connection to reality. I'm pretty sure Handmer is from Sydney or Newcastle.

You'll find that Australians outside of cities are big supporters of gun rights. There's also a lot of gun lovers in certain cities, Adelaide comes to mind. World's biggest country town, bunch of gun nuts (and serial killers) there. Highest rate of gun ownership per capita of any city in Australia iirc.

>>12796069
At least there might be enough still there to investigate.

>>12796556
For other launch companies and NASA it boils down to motivated reasoning. If they admit Starship is real it's a tacit admission that they've been too lazy/greedy/incompetent to do what SpaceX did and that their architecture is fundamentally wrong. That sort of thing causes mass management firings, tanks stock prices, and prompts Congressional hearings. It's much easier for oldspace paper pushers to ignore Starship until it orbits and then treat it as a black swan event because their bosses aren't savvy enough to spot the lie.

For what it's worth, I hope Tory Bruno sees this playing out and is making a list of hundreds of people to fire.

>>12796731
i cant think of anyone to invest in outside of spacex. "newspace" is a farce, elon holds all the talent and capital for good reason. the rest of the industry is grifters and sloths. venture capitalists need to get their cocks out of launch companies and into some fucking payloads. commercial stations, tugs, depots would be a nice start, but are they smart enough to move that way?

once you can reliably put 100t in orbit for not a lot of $$$ the money will come flowing in. this is probably more important that spacex's mars colony dreams.

>>12796759
basically everything we take for granted will have to be (or will be even if what works here anyway does the job fine) invented for use in space or on other bodies. it's potentially trillions of dollars worth of shit that will need to be done again and then serviced. people will become insanely rich on the back of it.

>>12796762

Algae based growth tanks. You can stack a huge volume of nested cylinders inside a starship payload, water extracted locally, nutrients are super dense and easy to ship. Algae doesn't care about day/night cycles and will take whatever sunlight you provide, virtually maintenance free, can be consumed directly, processed into feed for fish/chickens/whatever, used to create all sorts of oil, petroleum and plastic products, hell you could even grow lobsters and shrimp and shit in the same tanks. No need for gigawatts of led grow lights, just let sunlight do it's thing.

Nah, we need to privatize as much as we can because we've seen NASA prioritize keeping some administrator's jobs over Astronaut safety. NASA cares more about brown nosing some senator who's priority is to keep the lobbyist money flowing.

ULA tried to get away from the SLS with fuel depots and when shelby saw refueling as a threat to his giant one-use rocket he had the ULA executive replaced with a yes men.

We need to privatize space because we're seeing growing hostility from people who think that my movie is going to be reality.

>>12796775
> if there's money to be made building a spinning hotel around the moon then that's what will drive space development.

We need to be talking about industrial parks in orbit & not just hotels. Hotels would be attached to a lobby, that would have manufacturing,research,and fuel depot modules attached it as well.

Once we have fuel depots you could build ferries and use small rockets to go to big destinations.

I just saw a video where they told me everything wrong with the SLS and Arthemis is basically Trumps and Jim Bridenstine's fault.

It's not even an argument worth responding to
>give Obama credit for NASA's commercial programs despite him cutting the budget 40% and inheriting those programs from Bush
>blame Trump for Obama's SLS program that came out of Bush's Constellation program that came out of Nixon's Shuttle program
They'll try to pin Starship's success on Biden somehow, I guarantee it.

>Could just be some kind of disagreement with the Raptor comp and the flight comp, maybe they need to give the flight comp a little more authority/stronger priority value so it can overrule the engine comps more aggressively.
Not exactly how it works, but you have the general idea.
The main flight computer has ultimate authority. If it tells the raptor "MORE POWER!" the raptor won't go "nah, I don't think so". Unless an internal sensor on raptor is reading something like too high of chamber pressure and more thrust would result in combustion, the raptor doesn't "think" about when to throttle. It get told "full thrust" and raptor goes "got it!" and manages itself to maintain full power.
It seems more like the raptor could have had bad sensors on itself, such as the flight controller requested full power and the raptor thought it was already there.
They did abort after the first attempt due to raptor(s) reporting too high (chamber?) pressure, so its maybe possible something was out of bounds just enough to allow everything to still work without RUD, but the final landing burn on the single raptor was just enough to make it an issue.
Hopefully they were able to get back all of the data between modules, and the individual raptor readings to pinpoint the problem.

>>12796025
>For landing engines even sacrificing power to get lower throttle would be worth.
The big issue at the moment is they are playing within the SN# series to test a lot of theories and see what real-world results will be. The SN series are much lighter than production SS's will be(both in regards to size/propellant volume), so they have different parameters to deal with. Elon said the largest issue with constantly relighting all 3 raptors is that on the SN models, three raptors would have to throttle so low on landing that flameout risk is highly possible. Hence the thought of only one to land on the final ~150m because SN5/6 did it.
I do believe that relighting all 3 raptors for the flip, then shutting one down would be an ideal situation simply for redundancy. It will make software a lot more complex, but that could be the difference between and landing and a RUD.
Once we get to production SS, the weight will become more realistic and steady, so the raptor count will become more solidified, along with how many to relight and use at specific points during operation.

Only on ascent when tanks are full. Though I keep wondering what happened with the single central engine idea - currently the vehicle always translates when landing due to off axis thrust.

>>12797649
Probably couldn't fit the Vacuum raptors properly if the ground level raptors surrounded a central one but that is only a guess.

>send AI controlled robots to set up mining, production and martian base

I'm writing a sci-fi short story right now. What would a realistic acceleration for some kind of an anti-ship missile be? Right now, I have them at 8 gs for 14 seconds, and I'm wondering if a liquid-fuel rocket engine could do that.

>>12797688
Literally anyone following the space industry have seen this by now

>>12796040
That last bit is important. Typically white Cali tech people leave the places they go in shambles, and use their power to deliberately expunge the local culture and replace it with their own ""superior"" variant. It's great to see Elon not following this trend.

this would be a pretty cool job

Great slow-mo of the SN10 explosion at the end of the video
https://www.youtube.com/watch?v=2CpXxu9W0U8

>>12797693
Falcon Heavy hits 10gs+ and it's got a lot of extra stuff hanging off it that a missile or torpedo wouldn't. A common air-to-air missile can accelerate at up to 30gs for it's 5-10s flight lifespan. A space torpedo will likely not use a liquid bipropellant, it might however use a hybrid rocket with solid fuel and (relatively) stable liquid oxidizer. It could certainly accelerate at punishing speeds for the short 10-20s of it's lifespan.
Fast enough that it would be almost completely impossible to escape from or outmaneuver it once a ship was within the missile's effective range.

Acceleration isn't the issue, it's change of velocity and it's control capability once in flight since space warfare will NOT involve short distances. Projectile might take days to reach its target...

Rock overburden doesn't create heat and neither does pressure.
Rock is a shitty conductor of heat and when you have thousands of meters of it the rate of thermal flux becomes very small.
Common misconception that pressure creates heat, too. It doesn't. A gas going from 1000L to 1L in a perfectly insulated box contains the same amount of heat, but since it's more heat per volume the temperature goes up. If the box is not a perfect insulator (ie, every box in the universe), the increased temperature differential allows heat to flow out of the box into the environment. Eventually the pressurized gas will reach the same temperature as the environment, it won't just stay hot due to pressure forever.
Finally if you take a pressurized gas at ambient temperature and expand it back up to 1000L of volume, its spreading the heat energy from the one liter of pressured gas at ambient temperature across 1000L of ambient pressure gas, which means it cools off significantly.
Now you know how a refrigerator works, including why it needs a compressor and why the back of the fridge gets really hot.

>>12795842
I don't see why it would. BN1 can probably be mounted to the same launch platform that they've been using for the SN prototypes, it's not that much heavier in terms of dry mass and they aren't going to fill it up even close to its full propellant mass. Even if it can't, I honestly don't see why they wouldn't be able to whip together a second test stand with beefier steel beam construction and a clone of the same GSE hookups and shit.

>>12797759

>>12797807
Okay then how do you explain mines getting hotter the deeper you go then. I feel like “because you are closer to the mantle and you are closer to accretive heat and radioactive heat” isn’t the correct answer. It’s overburden heating bro I’m telling you

>>12795851
It's not economical. Also if you're in a place with low heat flow your generator can only run for maybe a decade before you quench the volume of rock you're pulling heat from and the temperatures get too low to boil water. Super high heat flow areas like Iceland are ideal for geothermal power because the heat is cheap enough to dig down to access, and the rate of thermal replacement is high enough that you may be able to run a geothermal plant for 50 years before needing to shut down to "recharge" your thermal mass for a few decades.

That's the major disadvantage of geothermal power; you aren't extracting energy from the flow of heat up through the crust, you're extracting energy from the heat that has already soaked up through the ground over millions of years to warm up a volume of rock. The rate of heat flow even in the very hot places on Earth is necessarily tiny, because rock is a shitty thermal conductor and to get a high thermal flow rate requires a massive temperature differential, to the point that if you wanted to run a 100 MW generator using just the thermal flux 10 km^2 of land area, that land would need to have such a huge temperature gradient that less than a kilometer underground would need to be like 10,000 degrees.

Let's come up with better/more autistic names for currencies of the space-faring future, I'll start;
>Valuicles (val-yoo-kuhls)
Like particles but for value, some economist eggheads may think of this idea and shill for it
>Grams
Because so many things will be viewed through the lens of muh payload mass anyway, it could make sense to refer to purchases of things by their mass because you can directly compare the cost of imports to the cost of native production [ie one ton of iridium shipped to Earth is worth 200,000,000 grams, for 5 grams you can buy a full course meal of naturally grown vegetables and meats on Mars, etc
>Chips
Because the early Moon and Mars colonies are likely going to develop their own underground system of currency not for any official reasons, but for keeping track of personal trades and services happening among the population of the colony. For example, 2000 people living on the Moon, everyone's getting paid in dollars which they can spend once they get back to Earth, but most things are heavily rationed and a lot of things are outright banned/discouraged, so a cheap form of physical, hard-to-counterfeit currency is created to let Sally from hydroponics make a profit giving blowjobs to the sexier millwrights which she can use to buy alcohol brewed by Frank from the electrical department who knows how to make decent wine under his bed but is very much not someone Sally wants to perform sexual favors for. To start off with this currency is completely valueless anywhere except on the Moon or wherever, but to the people living where it is used it's actually just as valuable if not more valuable than their Earth wages, because while they'll get their money when they get back from their tour, in the mean time they want to fuck and get drunk and get high like any other red blooded human.

these are the type of people who think robotic spaceflight is superior to manned spaceflight

>>12797908
i vote grams. that one is actually kinda cool.

>>12797837
Does this also fall into an explanation for what >>12797807 was addressing? Mines are hot because they dig deeper and deeper into rock that has had mil/billions of years to slowly heat up?

>>12795932
Wars around gas/ice giants and in the asteroid belt will include honest to god space-submarine-warfare.

>>12797908
Elon has already said there will be a Marscoin crypto. Proof of stake probably, since PoW mining on a tiny colony is a meme.

>>12797908
Grams would be based. "Oh that will cost 200 kilograms!". Very fucking intuitive actually
But would that mean value of all colony currency would be intimately tied to rocket prices instead of the local economy?

>>12797908
is sally from hydroponics hot?

>>12795951
I don't know shit about shit, but I think the point is to prove a single engine landing like they tried to prove a 2 engine flip. It shows redundancy. If one engine fails you can still flip, if two fail after that you can still land.

Its meant to be caught by the tower not propulsively land on the ground. Also there is no real benefit to testing it when starship still needs testing as they have the same engines, tanks and flight profile. Its also is basically a scaled up Falcon9 booster. So i really think they will just avoid testing it for awhile

>>12797908
I like the Artemis' novel idea of "slugs" that work as the grams that you can use to import stuff from Earth. The name slugs is terrible though, and Grams would be much better. This has the downside of not being an actual currency that you can control in any way, and heavily tied to how much you can import, but this should still work decently enough at first.
