artemis will end up being a starship that brings people from earth to a starship in LEO which takes people to a starship in LLO and then they take a starship to the moons surface where there is a base, which is composed of a starship. With any luck one of those will have an alpaca glued on
sss

/sfg/, post your post-landing doodles

FUCK JANNIES FUCK THE IMAGE LIMIT

>>12445597
I'm talking about the idea of a large rocket being required to carry the fuel & payload like the Apollo era instead of sending up the payload first, then multiple refueling launches.

I know that reuseable rockets are the future, but will entities like ULA continue to go down the route of a Saturn 5 that could be reused?

get ready for more my niggas

>its was actually waving goodbye...

>>12445626

What?

>>12445638
>Jurczyk
>Polish name
>Poland cannot into space
hmmm

>>12445665
google it

>>12445661
I’m feeling optimism about the future for the first time in awhile. This is fucking amazing.

>>12445664
It's the Rei of rockets.

They way it looked like it was landing slowly but still exploded to a giant mess was KSP as fuck. All the maneuvering before and that.

>>12445665
It's a relatively obscure compound that can be used as rocket fuel. Russians used it before. Made it once a few years ago as a fun chem experiment

>>12445664
Fugg we let ourselves grow attached to SN8, was she the prototype with the longest time on the test stand?

>>12445672
>digits determined that starship would explode and Poland would somehow take the blame
Doesn’t bode well.

>>12445677
Yeah don't get your hopes up
Musk is one of those globohomo freaks who want to put microchips in people unironically

>>12445648
I have an idea about using starship as lunar/martian bases.

Find a crater or other hole in the ground. Land the starship in it. Attach and inflate airbags. Then tip the starship over. Deflate the air bags and lower starship onto its side. Wrap the air bags around the starship. Cover in regolith. Attach a walk way tunnel to the air lock on the side. Set up solar panels, antennas, and radiators. Then run their cables and pipes to the starship. Open up the main tanks to the cabin for more people space. Future starship bring Space Ikea bits to reconfigure the interior for the new orientation.

>>12445682
I saw that but I thought that you were referring to some start up.

soon

I ran the stream footage through some analysis, and I think I found out why there was a pressure loss in the header tank

>>12445695
it'll scrub again and I will laff

>>12445693
if i were ultra rich id order a starship e2e to land on my private island then cut windows into it and use it as a chilling pad

>>12445665
RP-1 but way cooler and better

>>12445695
never

>>12445693
or send tunnel boring equipment to make a settlement 50ft underground, if you need more bedrooms you excavate them from the side of the tunnels.

>>12445693
>not just printing the hab, furniture, food and colonists on mars
NGMI

>>12445703
AWOOOOOOOOOOOOOOOOOOOOOOO

did any of the heat shield tiles fall off before the hard landing? It looks like they were still all there based on spacex's twitter video but I can't really tell for sure

>>12445664
brave little snate..

>>12445703
imagine being the guy that has to draw this for a bunch of boomers lmao

>>12445661
SN9 could literally fly in 2022 and it would still be miles ahead of everyone else desperately trying to make their F9 clones lmao

>>12445710

>>12445706
some people did that in a mining town in australia. unironically pretty great for climate control and expansion of your home, people have their kids dig new rooms kek. sometimes they hit a vein of opal when digging a new room and get a couple hundred thousand dollars

they're bolted on, aren't they? there's no way they're gonna fall off

>>12445704
so if starship doesn't use t-tab why is there green shit coming out of the rocket exhaust on the landing

>>12445661
Nah man it ain't happening this month. Would be too good.

>>12445724
>sometimes they hit a vein of opal when digging a new room and get a couple hundred thousand dollars
sheeeeeeit

>>12445683
Oh fuqq I just realized I won’t have SN8 to look at tomorrow. For the past month i’ve pulled up a stream on my other monitor. Now it will be barren :,(

>>12445677
i know what you mean anon

i even feel more motivated to work on my own little projects now. this sort of stuff is what makes life worth living. fuck cynicism, and fuck people who only see the bad in everything

>>12445728

>>12445729
The combustion chamber is made out of copper and the fuel pressure dropped low enough that regenerative cooling stopped working. It was running engine-rich.

>>12445729
engine-rich combustion and engine stuff being made out of copper

>>12445727
they shatter sometimes

>>12445661
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA

>>12445729
methane header tank had low pressure. that meant it ran oxygen-rich. Which means it eats itself ('engine-rich' lol). Green is due to injector plate being consumed which is partially copper or something

>>12445706

https://homesoftherich.net/2019/01/45-million-nyc-condo-with-2-story-great-room-floor-plans/

Even if it would cost you a half million to go to Mars you could probably buy such a martian tunnel condo for less than 5 million.

>>12445704
Bro how tf did they get Victor Glover and Kate Rubins for the Artemis video? The CGI artist that made that mistake will never hear the end of it.

I didn't think so at first, but after working through it I think there's a chance they pull it off.

>>12445708
Proonting colonists is the eventual goal. It takes nine months but it's the best method yet devised for increasing population.

>>12445758
Here's the thing. Once Musk goes to the Moon it's going to be the social media start up craze all over again, where college grads launch a platform.

Once Musk goes to the moon every Aerospace Engineering student will want to create SpaceX copy cats.

There would probably be 10 SpaceX clones internationally in a few years after Musk goes to the moon.

>>12445765
Humans don't need houses. The idea that people need houses is a scam made up by the real estate sector.

>>12445773
it takes twenty years, anon

>>12445773
>he didn't get proonted in 7 months
bro...

New Shepard flies for about 1 minute more than SN8 yet gets to 100km rather than 12. Is this the power of hydromeme?

>>12445779
this you?

>>12445780
It’s not reusable though.

>>12445780
it looked like vertical velocity dropped close to zero after they dropped down to a single raptor firing. i think they were just holding altitude until it moved into the right position.

>>12445780
no, it's the power of going supersonic
SN8 was subsonic the whole time and actually stopped and hovered at its apogee
if they just wanted to yeet it up for maximum altitude it would probably take about the same amount of time

>>12445774
Cut it out with this "rocketry=social media boom" crap again. Developing a reusable rocket from scratch would cost hundreds of millions, if not billions before any return on investment is seen.

>>12445793
I thought starship can't hover? wish they had put a altimeter on the screen for us

>>12445796
Starship CAN hover, did you forget about these flights?
it's Falcon 9 that can't hover

>>12445780
SN8 test was various engine test during ascent including but not limited to controlled shutdown of one engine at a time, and controlled hover at 12.8km with one engine for a "net zero" hover.

>>12445765
Nah. Building on the surface of Mars is exponentially more expensive than excavating rooms out of bed rock.

This is much better than what NASA wants to cram 20 people to live in to live in for 4 years, it's a prison cell but you would have personal space to jack off after a stressful day.

@Dr_ThomasZ

>#Congrats to @SpaceX for achieving this milestone. I stopped the NASA meeting I was in and we all watched the flight together. I walked away with a much better understanding of the profound differences of #Starship as compared to other rockets.

>>12445809
NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

>>12445799
very specific anon. what were the froyo flavors today hmm?

>>12445813
Its basic observations and analysis lmao.

I have a feeling Mars will have a ton of creepy "liminal spaces" like old service tunnels, mines, and disused habs.

>>12445817
oh just thought since you said 12.8km, everyone else was reporting 12.5

>>12445821
typo

>>12445795
If the Fed continues to pump money long enough they can get the 2nd cooooming of the bull market.

The Space-Com Bubble.

>>12445774
close but no cigar, it will be goverments who will mimick spacex, the only one who wont will be the us who will just buy starships of them.

probably china india russia and europe have some sort of shelved plan to quickly develop by themselves or with cooperation a falcon 9 then starship clone.

its just that a lot of the work done by spacex cant be kept secret so they are waiting to see how they do before copying them, just like it was much easier for the soviets to do the shuttle after the americans have done it.

Even just having concrete evidence that what youre attempting is possible makes an R&D project inmensely easier.. Everyone knows starhsip will be a revolution theyre just waiting on spacex to finish "standing up" so they can stand up on their shoulders

So like, now its safe to safe to say the Raptor is the first flight proven full flow combustion engine lel

>>12445832
Yeah. First and only.

>>12445826
Europe is nearly dead and in steep decline. They're never colonizing outer space.

Isn't he the guy who was opposed to Musk's idea of how we should go to Mars?

>>12445826
Japanese Falcon 9s

>>12445809
Other NASA employees, ULA, Boeing, Lockheed, BlueOrigin employees must be shitting their pants with this test

>>12445836
What a fucking asshole. He's literally shilling for Simply Orange

>>12445692
If space flight and ISRU become commonplace before it all goes to hell, mankind will unlock a near-eternal frontier that'll ensure the continuation of the rugged individualist spirit for millennia to come.

>>12445638
kringe, i think biden said he wanted to put a womxn of colxr in as new admin too

>>12445840
No. He's the guy who advocated for Mars and hosts Mars conventions where Musk and some other senior SpaceX employees are member of and donates their money to. He's made his suggestions/changes to Musks about Starship and talked with Musk in private convo.

>>12445840
he thought starship was too ambitious and that they should have gone smaller, but it's not like he ever opposed spacex or elon. methane ISRU is his baby and elon's putting up billions of dollars to make it happen.

>>12445832
it was safe to say that after starhopper

>>12445845
I want Musk to send some Shuttle Era NASA engineers ans building caretakers such as Janitors & Lawn keepers to some Low earth Orbits.

That would utterly cuck NASA,BO,and Virgin.

I say NASA because how they blew the shuttle program's premise of making space accessible.

>>12445832
Indeed. All the way to copper lining.

>>12445836
I don't think there's a single picture of that man where his expression doesn't make me chuckle at least a little bit.

>>12445840
He's convinced that a slightly more conservative path that focus entirely on an initial exploration mission is the better path forward. Considering Zubrin's spent most of his career pushing for a minimal-cost Mars exploration architecture to ensure it'd actually work, that's pretty understandable.

>>12445853
>>12445852

Oh, I thought that he was the guy who wanted to send people on a suicide mission to Mars with Mars Direct.

>>12445872
Yes and Elon agrees as well. One way mars trip for the initial colony is the only sustainable way to get to Mars. Just send them tons of food/supplies to last a lifetime and they're good.

>>12445693
I got a better idea

lunar dust is magnetic

You lay the starship on its side, magnetize it, then roll it to collect a layer of dust on it

>>12445872
Colonizing Mars means going and not expecting to return, dummy.

>>12445734
SN8 will not be on your screen.

It won't be in Texas.

It will be in your heart.

So how much money will Musk raise through private equity after today's successful flight?

>>12445734
SN9 is sitting in shade. She will come online in the coming days/weeks.

>>12445706
Yeah, well what company would you even get lunar tunnel boring equipment from?

>>12445885
SN9 will be there soon to fill the void

>>12445886
None, once Starlink gets to orbit, money will print itself for SpaceX.

>>12445826
hope the ruskies dig up the Uragan

>>12445893
...The Boring Company, strangely also owned by Elon Musk

>>12445898
>>12445901
Fucking kek

>>12445901
But you'd need a transport system in the tunnel. Loop System which boring company makes. With a vehicle, which Tesla makes. And battery/solar power which Telsa makes. Which Musk owns.

>>12445905
>ULA pivots to providing lunar rovers as competition against Tesla
>They're gas powered

>>12445835
europe is fucked, but it still has enough punch that if they combine all of theyre countries together they can at least rival russia and china, or maybe achieved something while partnered with russia and or china

expect to see a lot of real politik in play here, pragmatism will be the name of the game when united states has a starship but no one else does, it will be like a world in which only one country has cars and trains but the rest are still just using horse driven carts, a lot of idscrepancies will be put aside at least temporariliy to even the playing field, at least temporarily

>>12445692
>who want to put microchips in people unironically

>>12445893

Musk's boring company.

or

treat it like the construction industry where you have companies competing for customers.

https://www.westinghousenuclear.com/new-plants/evinci-micro-reactor

https://www.youtube.com/watch?v=Sh6BKKFxN_g

That's one company that produces reactors, throw in companies from countries like France, India, China,and Japan.

You'll have companies competing with solutions that takes waste heat to distribute it so it won't go to waste.

>modular micro reactor
How much does it cost? 10x more than Solar panels + batteries? 100x more? 1000x more? 10000x more? Yeah, its not worth it due to expensive hardware.

>>12445872
Mars Direct isn't a one-way architecture. You're thinking of that scam, Mars One.

>>12445942
nicotine will be delivered via gum or patches

>>12445706
It's called Cubic, tovarishch

>>12445944
solar panels must be around 10.000 times more expensive than nuclear reactors in terms of power generated, particularly in mars

>>12445944
Solar panels+Batteries sucks on Earth and it sucks even harder on Mars.

>>12445952
i can at least hit the juul right?

>>12445849
He give so little of a fuck about space that the post will be vacant for half of his term.

>>12445997
have you ever worked with the government on nuclear stuff?

>>12445988
a reactor that costs 1 million but has people using it to justifiy 999 million in theft does not cost 1 billion, just as it does not cost 50 billion to put 50 tons of cargo in lunar orbit, even tough thats what sls will cost

>>12445994
>Wheelchair or creepy mind reading device implanted in your body like something from an alien abduction story? You decide

How the hell does some creepy microchip help a quadriplegic anyway?

>>12446001
the point of modular micro reactors is that they're produced in factories in large numbers instead of custom jobs that take decades.

>>12445992
>cyclopropane
I just remember the James Burke Connections episode where it's used as an anesthetic, and a very flammable one.

>>12446001
SpaceX is not working with the government to colonize Mars.

>>12445661
IT'S SNINE TIME

>>12446006
There's no such product online. It takes ton of capital/regulatory processing/time to put a nuclear reactor into space. By the time they get anywhere close to actually producing a viable product, SpaceX would have already gotten hundreds of colonies on mars using solar panels.

>>12445992
It's a clean buring booster. I tell you hwat.

>>12445964
>the metric that matters is just raw dollars baby
No, it's man/hours and resources required for maintenance.

>>12446009
cyclopropane is no more flammable than any other hydrocarbon, but it's much more expensive than propane or methane
methane is the cheapest and has the highest ISP and pretty good density
propane has the best density-impulse and is fairly cheap, with nearly best in class density and ISP only slightly less than methane
the only issue with propane is that nobody has ever used it before so there's a bunch of FUD about soot
also it's harder to ISRU, methane is the best option for Starship, but everybody else who's not trying to go to Mars should be using propane
>>12446013
then they are not using nuclear energy

>>12446022
There's no EPA on mars. Would you want to be the bureaucrat who rejects nuclear energy on Mars?

>>12445661
I don't see it happening, but I'm so high on hopium right now I'll accept it

>>12446030
ah, right
Nuke Mars, brother

>>12446016
https://en.wikipedia.org/wiki/RITM-200

Small modular reactors have existed for decades. They're used in vehicles, primarily.

>>12446031
Pitch over was so smooth, you can also see it slide down it's fins. Also clearly "catches" itself with it's front fins

>>12446005

>>12446036
They've not been used in space or tested in space.

>>12446022
>then they are not using nuclear energy

There is no EPA on Mars, dummy.

>>12446031
What would have happened if they nailed it perfectly with out it blowing up?

>>12446037
Superb control too. Its amazing how they've calculated all that shit.

>>12446037
still can't believe those piece of shit aluminum foil fins worked so flawlessly the first time they were tested

>>12446044
This but a nosecone

>>12446044
Something similar to today, except none of the garbage "Elon Musk rocket explodes in catastrophic failure" tabloid news

>>12446041
>Goalpost successfully moved

Who said anything about "space" anyway? We're talking about a power plant for Mars, not a space station.

>>12445992
but even sub-cooled propane is less than half the density of cyclopropane

>>12446044
have you ever seen a dog catch a car that it's chasing
>>12446041
that's not the problem, the problem is that everybody who wants to use them needs to get the blessing of the US Government

>>12446044
Thunderf00t would make a video trying to debunk it from an economic standpoint, calling it a glorified redstone rocket

>>12446037
that start of the video where it emerged from the smoke and righted itself was an incredible moment. i was beside myself when i realized it was actually working.

>>12446021
That counts as dollars, retard. Cost.

>>12446052
that's because it has half the hydrogen

>>12446039

>>12446022
>propane has the best density-impulse and is fairly cheap
Propane has the best density impulse of the straight chain hydrocarbons. Cyclopropane is expensive but its density impulse is way higher. In fact the density impulse of cyclopropalox is probably higher than most hypergolic mixtures.

>>12446016
Kilopower? Nasa already built prototypes for 20 million.

>>12446063
Cool selfie

>>12446066
how is its density so high?

>>12446060
For a martian colony terran currencies might entirely lose any value at some point.

>>12446051
We don't have teleportation technology. Even if we had one, there would need to be studies on what happens when nuclear reactor is teleported.

>>12446053
Its also problem, NASA/DoD/EPA/US Gov would not allow any nuclear tech to space without proper study on how it affects the reactor/environmental impact/political impact/etc.

>>12446056
He's a grifter like all of the migapede like Tim.

I thought they were actually gonna try a 360 degree flip lol

That turn was exquisite however

>>12446053
>that's not the problem, the problem is that everybody who wants to use them needs to get the blessing of the US Government

Just pay them off. Elon Musk needs to become a swamp monster like Boeing unironically.

>>12446079
No, its better to go with path of least resistance and actually do engineering.

>>12446075
what if you built one on Mars and didn't tell the US government
and when they complained you just dropped rocks on them

>>12446083
Engineers came up with perfect supermega reactors years ago.

>>12446072
That's how all "transhumanists" are gonna look. Sterilized bug people with no souls controlled by megacorporations.

>>12446061
Actually it has a hydrogen to carbon ratio of 2 (six hydrogens and three carbons), vs ~2.66 for straight chain propane. It gets rid of two of eight hydrogen atoms.

I believe that the burn will be clean, and it will not soot, but have no firm data to back it up because nobody's ever run a fuel rich turbopump on propane and oxygen

>is soot really such a non-issue?
He's in love with propane but it can't be used in a FFSC engine because it makes soot deposits under those conditions. In an ideal world, propane would be the best performing hydrocarbon, but in an ideal world we'd actually be using hydrogen, because in the world of the ideal you ignore all of the drawbacks and focus only on the benefits.
Soot formation is what fundamentally limits the performance of some hydrocarbons, because they cannot be used in the best engine cycle. The difference in performance between the best feasible oxygen rich staged combustion methalox engine and the best feasible FFSC methalox engine is large enough to overcome the difference in performance between the best ORSC methalox engine and the best ORSC propalox engine.

>>12446124

But why? What is your logic

>>12446145
>you have no proof

Fine, I'll explain my logic, retard.
Take something we know is sooty, kerosene (aka RP-1). Generally RP-1 consists of a few long chain hydrocarbons, but I'll pick C12H26 as the average constituent.
Next look at something we know isn't sooty, methane. That's easy, CH4.
I will be considering 100% pure fuels in my argument, so don't come to me with "b-but take the sulfur out!!", there IS no sulfur in these fuels.
To understand why propane cokes, you need to understand why coking deposits form. Basically, under the temperatures of carbon-oxygen combustion, hydrocarbon molecules break down into various species of highly reactive radicals. The thing to know is, only the hydrocarbon radicals that have a sufficient number of hydrogen atoms still attached remain volatile gasses; get too many carbon atoms with too few hydrogens and the resulting radical acts more like elemental carbon, which as we all know has the highest sublimation point of any element.
Now, when methane breaks down, the species that can be produced are CH3, CH2, CH, and naked carbon. However, the concentration of hydrogen in the decomposition gas goes up even as methane radicals are losing hydrogen, and the net result is that carbon radicals never manage to break down all the way to pure carbon. Since even CH is a volatile gas, no coking deposits form.
In short form, RP-1 doesn't have enough hydrogen to prevent elemental carbon from forming, and worse some of the radicals produced can still have hydrogen yet not be volatile (say, C6H8 as an example). This leads to thick black tar deposition.

Look at the H to C ratio of each fuel. Methane has 4:1. Kerosene has 13:6. What does propane have? 8:3. In decimals, that's 4, 2.16, and 2.66 respectively.
Given that propane has a H to C ratio far closer to kerosene than methane, I predict it cokes.

>it's about the length of the dissociated hydrocarbon radicals, and I predict propane is short enough not to coke
>Three carbons in propane is much closer to the one carbon in methane than it is in the twelve carbons in your dodecane example
I disagree about the length of the carbon chains being as significant a factor. Acetylene has only two carbons yet cokes extremely easily even burning in an open flame in atmosphere, because it has a H:C ratio of 1.
If carbon chain length were a factor, then propane and neopentane should both burn with the same level of soot formation. If it is not a factor, then neopentane should be more prone to coking than propane. A different test would be to compare burning ethane (C2H6) to burning ethene (C2H4). For even more data you could try comparing a gas mixture of equal molar concentration methane and acetylene to cyclopropane. If my theory of coke formation is correct, then in experiment 1 neopentane should produce more coking, in experiment 2 ethene would produce more coking, and in experiment 3 both gas mixtures should produce the same degree of coking.

(formerly sneight's)

>>12446276
anything with a double or triple bond has increased coking
if the temperature is high enough, then whenever two of the double bonds hit each other then they combine, which doubles the length of the chain
this happening repeatedly is why ethyne cokes so easy

>>12446268

Once Musk goes to the moon I think there's going to be a big block back toward how NASA focused on SJW stuff.

My hunch says that there will be a lot of finger pointing in all directions, and right now there's a big blow back growing against SJWs in general.

Reddit would drive a steam roller over Liberal Arts degree professors if it meant they would gain debt forgiveness. I support the idea of making the universities to pay for the debt of the SJW degrees, that would cripple the universities. Once they're crippled fiscally I would integrate trade schools into their campuses to have the working class rub shoulders with the commie elite that hates their guts.

If the temperature is high enough and there's enough free hydrogen radicals around those carbons don't have much of a chance to find each other, and even if they do they're getting broken apart again/having enough hydrogens bonded to them to keep them volatile.

it just the lessons learned from history. Even the switch from medieval life to industrial life feels so alien that it fucks people up and makes them go really crazy.

Like, just spending too many hours in a factory instead of out in the sun, just having sexual repression everywhere, being told that its wrong to show your instincts, being told sexual desires before 18 is completely unnatural and even after that it has to be done very sparingly and with a lot of fear, it generates all kinds of extreme psychological fuck ups, thats why first world people bond with third world people all the time, they are totally cautivated by someone who is still able to just be calm around life and not be traumatized and scared of every fucking experience.

It's not shocking that people support Space.

The problem with NASA is that their shuttle program degenerated into a jobs program for the Administrators. The public lost interest when NASA stopped innovating.

It also helps that we can watch Space X's progress daily.

That's not going to happen, short of the west liberal order collapsing ,SJWism is useful to liberal societies as it facilitates the conflict of the high-low vs middle, in addition to keeping power relations opaque, and as a means of denying official power.

I forget where I read this years ago, I think it was atomic rockets, but life aboard a spacecraft on a long term mission or on the base of an alien planet is not going to be some grand libertarian paradise, but rather something incredibly regimented and authoritative simply because there's so many ways for things to kill you.

ascent was actually nominal in spite of it looking kinda jank. And the gimble when an engine shut itself off was to nullify the negative force, to put it stupidly. I'm guessing they wanted ascent to be nice and slow so that they could focus on falling and landing.

I want to support people's stock trading such as making 25k for singles and 50k for couples of untaxed profit each year. As well as ending the PDT rule.

So if you made 15k off the stock market this year then you get to keep every last cent because you didn't hit 25,000.000 dollars of profit.

Once you do go past 25k you'll get taxed with the current tax rate. Today's markets beats the dot-com era due to how accessible the markets are, and the elimination of commissions.

So it's not like I'm upset that the guy could make a million dollars, I'm mad at his "Fuck you, I'm getting what's mine!" attitude of his. He's no better than the politicians that we have.

Boomers cry about abortion while they know that they've created so much debt that we're spending 340 billion on the interest each year now. That's money we could use for infrastructure such as new water treatment plants.

I'm retarded so I'll calculate

The most dense thing in minecraft is a 64 stack of gold blocks. Conveniently each block is 1x1x1 meters, so every stack has a mass of 1,235,200 kg.
Shulker boxes are portable chests 1x1x1 meters in volume, which have 27 inventory slots. This means that the single most mass you can carry in ONE inventory slot in minecraft is 33,350.4 metric tons.
A player has 36 normal inventory slots as well as one off-hand slot, for a total of 37. Therefore, the maximum amount of mass that a player can carry in minecraft is 1,233,964.8 metric tons.

So that's definitely a lot, but it's nowhere near enough mass to make something the volume of a typical backpack (~ten liters) smaller than its Schwarzschild radius. Neutron stars for example are many orders of magnitude more dense AND are much larger, yet are still not black holes (obviously).
To put it simply, you are fake news.

Not if it's make of clear plastic. In fact most plastics are a superior radiation shield material compared to water; higher density of hydrogen atoms plus carbon also has a lower atomic mass than oxygen.

Ah, you beat me to it. Also I forgot the offhand slot, kudos.

At worst you could call it a successful test and a partial failure. The flight's purpose was to verify that the aerodynamic control was gonna work, with the secondary purpose of verifying that they could maintain control through the backflip maneuver, and a stretch goal of actually landing the thing.

What would you classify SN8’s flight as? It doesn’t seem fair to say that this flight was a failure because it did exactly what it was supposed to. However it also didn’t land so it’s not a success. Thoughts?

>>12446564
I replied to your deleted post with this >>12446562

>>12446549
The radiation we are concerned about goes through 10 metres of rock. Plastic won't do shit except for UV.

>>12446564
seems reasonable. It's certainly not a failure considering the criteria for a "success". It's a success by their testing standards but not a success in the sense that it exploded.

The problem here is that this sort of thing is rather without precedent thanks to SpaceX's unique testing platform. Explosions are 100% expected. Not so with every other company.

>>12446564
96% success, with a bonus 10% for the sick green flame and badass explosion.

So 106% successful. A+.

Transhumanists seem primarily concerned with destroying the human experience because they personally dislike it due to their own personal failings.

"I'm weak because I don't exercise, but it'd be so cool if I could get robot arms and beat up Chad!"

"I'm depressed because I stay inside on the computer all day, and don't exercise, but what if we had chips in our heads that made us happy?"

Genetic alteration could be cool, but I'd only use it to become more animalistic.

>>12446564
The goal of SN8 was to test all of the new aspects of the flight, header tanks, aero, 3 raptors, relights, belly flop, flip maneuver, etc. They already tested hover and landing on SN5 and 6. At worst I'd say it was 95% successful, since they achieved all the new difficult parts and old failed with something as simple as tank pressure. Depending on what the cause was (for example if the tank was just underfilled deliberately) it could be argued that the test was actually 100% successful since the actual landing is already a known quantity.

>>12446564
if it isn't a success it's a failure. inventing new categories just to try to keep the failure column at 0 is a cope.

>>12446565
Thanks and yeah I had a typo. I thought about calling it a “partial failure” too but SpaceX seems to think the flight was not a success but did what it was supposed to. I have no idea what to call that but labels like “failure” and “success” don’t work here. Even if SN8 exploded on the pad it wouldn’t be a failure per se, but it would most definitely be a partial failure.

>>12446567
This has never been done before, but the closest are the Russians and their N1, which most definitely did fail on each flight.

Remember when SN3 imploded because some intern pressed the buttons in the wrong order? SN8 did everything it was built to do and surpassed all expectations. The only failure is that there's not nearly as much of it left to scrap for Cybertrucks.

>>12446591
There should at the very least be a category between “Partial Failure” and “Success” which infers that the mission completed the majority of its objectives but not all. Like for example the CRS-1 mission is listed as a partial failure due to the loss of the OG2 spacecraft, despite the fact that its main mission was successful (delivered dragon to the station).

>>12446591
sn8 was built to land in one piece and it didn't. that's fine. it's a test article. there's nothing wrong with failing on a mission nobody really expected to succeed. you can have a promising failure, you can have a failure that you learn from and build from. it's not a dirty word and there's no need to shy away from it.

They use polyethylene as shielding all over the space station you fags.
I tried to post a link but site is being retarded, just google "Polyethylene radiation shielding"

trackeranon here with a progress report:
Tracking the tip of sn8 and the middle of the bottom to get orientation data, some preliminary analysis suggests the rate of rotation maxes out at around 40-60 deg/sec. By no means perfect as there could be some perspective not taken into account, and still have to try to smooth out the data, but should be good enough for some rough g-force estimates. Don't worry about the tape measure on sn8 only showing 43m. I originally wanted to use it as a known length but apparently you can't tell the calibration stick to keep a fixed length when while its endpoints are changing.

OH NO SHELBYBROS WE GOT TOO COCKY

>>12446607
Mark 1 was built to fly to orbit and it never even static fired. Was Mark 1 a failure, or was it a pathfinder that showed their manufacturing techniques needed to be reconsidered?
SN8 existed to test new all of the new aspects of the flight, and it succeeded in everything except potentially regarding the methane header pressure.
I'm sure SN5 and SN6 were built to land without leaning hard to one side, but they hit the ground too hard and smooshed up their landing legs. Does that mean they were failures because the legs got wrecked?

Yes, when you pop on the pad I'm pretty sure that qualifies as an unmitigated failure.

>>12446566
Rock is a shitty radiation shield material though. Trust me, I'm literally a nuclear science student.
Water is actually more effective at blocking radiation of all kinds than rock. Water is especially effective at blocking neutron radiation but it also attenuates gammas very well. Alpha and beta are so easy to block it's hardly worth mentioning other than to watch out that you don't use a thin metal shield to block beta because the Bremsstrahlung x-rays produced can be nasty and are far more penetrating.
For blocking cosmic rays you are concerned with avoiding any and all Bremsstrahlung x-ray production as well as rapidly attenuating all of the particles produced when high energy heavy nuclei hit your shield and shatter into small high energy nuclei. Both of these factors mean you want light elements in your shield, because if a light high energy particle strikes a particle of similar mass they both end up splitting the momentum and velocity ~50-50, but if a high energy particle hits a heavy atom the split in terms of velocity looks more like 5-95. Slowing down particles rapidly increases both the likelihood and the strength of more interactions with matter, meaning if you have light elements in your shield material the stopping power actually goes up dramatically.
Anyway, rock can still work, you just need a shitload of it and it's not transparent. If you're living in a cave 20m down you are fine. If you want to live under a dome that you can see through and not get any cosmic ray dose though, you need to make sure that dome has a very high hydrogen content.
Personally I don't think cosmic ray flux is high enough to be a significant risk even if you lived on an unshielded station in a deep space solar orbit, because it'd only give you a few times your legal dose as a nuclear energy worker and those dose limits are set extremely low for caution's sake. Remember, the paper it takes to print and sign a waiver is really cheap.

>>12446619
I get his point though. If, say, Artemis 1 lifts off and places Orion into its high earth orbit, but fails to inject it into a Trans Lunar Injection, would you call that a success or a failure? It is a test flight?

That being said SN8 literally had no purpose other than to see what problems existed. But one could argue that most rocket’s maiden flights are like this. The N1’s first flight was a massive failure but it DID show the Soviets what they could improve on.

>>12446634
That's pretty much what happened on Apollo 6 and I don't think anyone would have any problem calling that a partial failure since they didn't get to perform the direct abort like they were planning on.

>>12446621
>earth's magnetic field
>blocking cosmic rays
You've literally just outed yourself as being a dummy know-nothing. Even fucking airliner pilots get cosmic ray dose because that shit goes right through our pathetic magnetosphere without even slowing down.

>>12446634
I'm not saying you couldn't consider it a failure, but it depends on what you're measuring. "SN8" as a test vessel could be deemed a failure since it didn't survive and it technically wasn't a test to failure like SN7.1.
However the SN8 test flight fulfilled every objective that was expected. What additional data would have been gained if SN8 landed? If anything the fact that the header pressure went haywire at the last second was the best possible outcome since it revealed a potential weakness in the design AFTER confirming that every other design decision worked flawlessly. If it landed we'd just learn that the shitty temporary landing legs continue to be shitty and temporary.

>>12446634
>If Artemis 1 lifts off and places Orion
>places Orion

>>12446644
I’m willing to agree with this but SpaceX is pretty adamant with the idea that the vehicle successfully completed its objectives. Now I know that’s cope but keep in mind, an Atlas V once a payload into a lower than planned orbit which the customer said was successful, but because ULA didn’t like the orbit, it is still seen as a partial failure. I think success and failure are subjective

>>12446656
It's hard to compare it directly to anything like that because there was no primary objective to this flight other than "let's see what happens" and the flight worked to the degree that they saw how every happening happened. If it RUD'd on the pad it'd be a failure, if it RUD'd before belly flop it'd be a partial failure. The fact that it stressed every one of the new systems means it completed all of it's objectives.

>>12446647
What’s funny is that SN8 made it through EVERY portion of its flight. A failure on ascent for example would suck but be okay because, well, that’s why we test things. But she made it all the way to the finish line! It’s like if a person ran a marathon and cut the rope at the end but ended up passing out without crossing the finish line.

>>12446211
so. fucking. close.

>>12446663
That's why I say the test was successful. If it had malfunctioned any earlier then it would be a partial failure because only a portion of the components would have been tested, but because it made it all the way back they know the engines can be shutdown, they know the aero works (both in terms of aerodynamics and in terms of physically controlling them), we know they can switch from main tanks to headers, we know they can relight the engines and we know they can make an accurate landing from 20,000 feet. The only question is what caused the header tank pressure issue and there's a decent chance it's a minor configuration error or a stuck valve or something.

Nuclear energy is older than spaceflight. With Starship it would be trivial for SpaceX to deploy a uranium enriching plant to the Moon, to produce fuel to be deployed to Mars. The challenge of non-sanctioned nuclear power isn't technical, it's avoiding Uncle Sam bombing your centrifuges. Not a problem when you're the one giving Uncle Sam rides into LEO, and your plants are on the Moon.

>>12446675
This. I also can’t come up with any other spaceflight missions that ended in a similar manner either, except maybe if in an alternate world STs-1 ended with the shuttle’s landing gear breaking upon landing while still demonstrating a successful flight.
