That's not what this is. If you push it, you can describe it as a filibuster.
But, let's be honest, SpaceX isn't doing it to spread American ideals.

Friendly reminder, if Biden wins, buy stocks in Raytheon and Lockheed Martin :)

>>12316835
"American ideals" have nothing to do with manifest destiny you fat cunt and its a good thing no one is spreading your civnat McDonald's worship.

>>12316845
Manifest Destiny is wholly american, you retarded faggot.
It's an american exceptionalism idea that believes that America has an obligation to spread its superior virtues and institutions.

Bitch, what? America isn't going to 'spread its superior virtues and institutions' by removing boomers from boca chica.

>>12316879
Critical thinking dumbass. They remove the boomers they can increase the rate at which they can test and can move to Mars faster. Making the comparison of kicking out boomers and taking over their land is just a joke, but it will actually help with expanding (to Mars that is)

>>12316879
>America isn't going to 'spread its superior virtues and institutions' by removing boomers from boca chica.

Yes it will. Not having to worry about annoying regulations means SpaceX can progress faster and harder

>>12316835
Elon Musk is nearly as pro American as Zubrin and that's saying something

hopefully Elon understands what being an American is all about when he gets to Mars. (Having lots of guns)

this one has been canceled. Next closure the 9th

What material does spacex use for their heat shield? PCBY or something like that? Also any good papers or videos that explains the physics behind their heat shield? How exactly does it work, and how is it better than the shuttle's freeze dried ice cream tiles- is it ablative or something?

>>12316991
TUFROC

>>12316991
They're denser and tougher than Shuttle's tiles, and they work by being really good at radiating heat, withstanding high temperatures, and NOT conducting heat.

>>12317011
>>12317031
Thanks. I'm a geologist by schooling but I've recently been binge watching nilered's videos and it has reawakened the geochemical/material science autism in me. I really want to know more about non-ablative heat shield tech.
I wish we knew a way to make superconductors work at room temp / SUPER high temperatures because that would give us a way to make heat shield superinsulators. But I guess that won't really work because you need to keep it at the critical temp which is always low in order to get the weird quantum effects.

>>12317044
Hopefully we figure out warp bubbles like the ones the aliens use which would insulate craft from experiencing g-forces or ablative heating

Is there an article somewhere comparing the Starship heat shield to the Space Shuttle's?

>>12317063
Starship heatdhield is going to be modular, cheap, welded. Shuttle is highly engineered, expensive, not modular, glued together, etc.

>>12317063
I've been on the lookout for a few hours now. I've mostly found monotonous scientific papers. If I find a nice video or article I'll post it. The shuttle's heat shield was such a piece of shit. The new generation stuff is really interesting

>>12317079
Oh I wanted to ask that earlier. I know a lot about their plans to go with the universal hex shape, which makes sense for like 99% of the cylinder body... but how will that work near the tips and wings of SS where the shape becomes way more complex. The whole idea for hexagons is to keep it simple but won't they need SOME custom shapes to fit the places I mentioned?

>>12317091
Maybe Elon will mention it in last week's update

>>12317091
Maybe some heatshield need to be cut in half but overall hex will do fine.

I hate to make this about politics.
But now that Biden is probably going to be president, what happens with the current US space program?
Does it get de-funded?
Does Elon keep getting government contracts? Is he self-sufficient enough to do it without US support?

This was one of the main factors for me when thinking about who I wanted to win.

>>12317125
Ask that question after the civil war ends. Could last years

>>12317125
2024 Artemis deadline is probably dead but I don't expect him to rock the boat too much

>>12317125
The last time Biden spoke on anything space related was in 2008, when he said China should be made a full partner with NASA. So yeah, no mars for us and Chinese flags on our rockets.

>>12317146
yeah fair enough.
I guess my concern was the drop in budget and non-interest in space during the Obama administration.

>>12317125
This should give a good idea
https://spacenews.com/key-senator-raises-doubts-about-2024-human-lunar-return/

>>12317159
I really hope you're wrong.
If you're not, I hope Elon has generated enough interest and reason for a space program that it progresses anyway.

>>12317125
Nah these are all good questions. We've been discussing it here the past few months anyways. I should start by saying that because Biden has been completely silent on his space policies no one knows for sure (not even NASA). But between wild conspiracies and smart conjectures here is what I have come up with:
>what happens with the current US space program?
Unknown at this time. Biden might very well keep Bridenstine because a lot of people on the left really like him. He might equally kick him out and select some climate science goon
>Does it get de-funded?
>Does Elon keep getting government contracts? Is he self-sufficient enough to do it without US support?
Hmmm. Considering SLS was started under the Obama-Biden administration (not to mention the fact that SLS is almost finished despite the memes and they have already started building gateway) I would wager that Artemis will probably still happen. Albeit a long time from now. Elon will most likely keep his contracts
>Is he self-sufficient enough to do it without US support?
In the early days of SpaceX Elon was completely reliant on gooberment money. To the point where he has sued a couple of times to get contracts that were unfairly given to others. He is a billionaire but throwing all of his personal money in his company in the early days was not his style. But now between his tesla shares and starlink he is likely about to become the richest man in the world. Starlink was literally designed to generate a fuck ton of revenue to self-fund spacex for the future so yes Elon is now self-sufficient enough to survive even if NASA cut off every contract for the rest of time.
>This was one of the main factors for me when thinking about who I wanted to win.
Obviously Trump was better for manned spaceflight in the short term, i.e. Artemis because it was stroking trump's ego. But we might still see cool things under Biden. Maybe. Maybe not. Both parties are gay in their own right.

>>12317163
Foust is based

I mean it's pretty obvious that Biden and co are going to gas every single trump programme ever so throw everything NASA out the window. But so long as they don't cuck SpaceX too hard with regulations or commie shit they are pretty much set for funds with starlink.

We'll see I guess.

>>12317167
I'm optimistic that the ball is already rolling for a lot of this.
Artemis has the goal of getting the first women on the moon, so I guess that gives democrats a reason to support it for political purposes.

>>12317183
Exactly, but the way I see it we will probably only see 2 or 3 landings. (maybe a few more). They will get the first woman on the moon and be done with it. And then just turn gateway into ISS 2.0. That way costs will go down and they can still give the thing a use. Sad really, but this is the reality I see

>>12317183
>Artemis

Dude it's 100% cancelled, It's an orange man program. Have you learned anything about politics and NASA from the last, like, four decades? And now the grudge cancelling will be on 10000x steroids because orange man bad.

>>12317189
I really hope at that point private space as kicked off more than just in a spacex capacity.
Either that or some other western countries start getting involved once it gets cheaper.

>>12317196
I'm not American.
But as I said, I'm optimistic.

>>12316739
Honestly if they expect enough overpressure to blow out windows that is well into permanent hearing damage. SpaceX should have to put them up in accommodation outside the area.

I feel as though it's an end of an era although it never really got going

>>12317263
I don't think they're going to crush Space force due to the importance space will play in the future of conflicts and warfare

There are three tenants of Contolism:
1. The Earth is sacred, and must be protected as the birthplace of mankind.
2. Mankind was always meant to move into space.
3. Mankind's offworld colonies must be self-governing.

1. isn't unique, 2 is basically the premise of this general, and if you hate 3 then I don't know what to tell you, you fucking communist

this is supposed to represent Apollo 11's trajectory during its TLI, but it just seems a bit wrong to me

>>12317386
it looks right when you account for earths Axial tilt

>>12317386
Oh I see what you're saying. Yeah I think it's weird because we are looking at a cross section of earth across the plane of the moon-earth system. In reality this path is swinging outward, and I think the moon is also slightly inclined so all we are seeing here is the trajectory doing its inclination. I don't know how else to describe it

Okay I made a pic kinda describing it. If you play KSP you'll know that my orbit around earth is wrong but hey it works for a simple explanation. I think this is what they were going for?

Also I would love to see SLS killed, it would shake up oldspace hard enough they might try being competitive again.

Arianne 6 is most retarded. Even more than SMART Vulcan.

>>12317715
It's a simplified, possibly less expensive design that is transitional. You don't change philosophy and make a complete 180° turn in government agencies as fast and reliably you do with private companies. Unless you're China maybe, for other reasons.

>>12317709

Elon isnt wrong. Anyone worth their salt is developing reusable rockets.

>>12317718
The reason China can respond to change is long term planning. Few western politicians care about what happens after their terms so don't plan ahead while China sees SpaceX and goes "so it is possible and cheaper therefor the future, let's do it".

>>12317725
Rightfully so, you are most correct.

>>12317718
"Ariane 6 is transitional" is a massive cope. The only thing Ariane 6 transitions us into is a world where euros are forced to stop buying their own rockets if they want to retain any meaningful capability.

>>12317722
didnt the russians say they arent developing this after they got bullied on twitter?

>>12317729

>The only thing Ariane 6 transitions us into is a world where euros are forced to stop buying their own rockets if they want to retain any meaningful capability.

But they allready are buying foreign rockets. A handfull of Soyuz rockets per year.

>>12317722
ISRO is working on two resuable designs, falcon-style with gridfins and another one like dreamchaser.
Hope it takes off, or else our space program will be obsolete.

>>12317734
No they decided to stop talking about it. But really who knows how serious they are about developing it in the first place, any change in plans in Russia has to be cleared through the oligarchs first

>Europe the "scientific" continent
>Can't send people to space
Even China and soon India can do it. What's your excuse Europe?

>>12317729
There is no taxpayer or publicly backed reusable launcher system being developed in the US either. SpaceX is an anomaly (thats has been successful) for a system that since the end of Apollo has seen gradual stagnation and little interest for innovation over political and economical oriented policies. Europe will retain alla capabilities but will lag behind, predictably so for ESA receives even less attention and fundings than crippled NASA.

>>12317739
Fugging depressing, because imo they had a better space program (except the moon part). Hope the health rumors are true and Vlad goes away.

Not enough money, we spend all we have on state-funded homosexuality and demographic replacement.

>>12317743
Didn't New Glenn get $500M from DoD?

>>12317717
Even if the chinks are somehow incapable of making it work, it's still such a delicious BTFO of oldspace sticking their fingers in their ears about reusability.

>>12317753
I suppose I didn't express myself correctly: what I meant to say is that companies such as SpaceX, BO, VO and so on are not products of the declining space industry - though have depended on them and their previous workers, employees and know how to succeed. Government contracts were foundamental to their ascension, but they are not a product of them.

>>12317753
They did but all further DoD funding has been cut because they have nothing to show for it.
The more times goes on the more I think Bezos only got into rocketry because he wanted a cut of the billions Boeing gets for doing nothing.

>>12317735
Yeah, and Ariane has been dropping its launch rate YoY for some time now. Ariane 6 isn't what they need to stop the trend.
>>12317743
>There is no taxpayer or publicly backed reusable launcher system being developed in the US either.
If your government treats space as a jobs program like US & Europe, you need a healthy private environment, which the US does and the Euros just do not. The other option is to have a government that makes decisions guided at least somewhat by real world performance like China & India, which just isn't going to happen in complacent Europe.

>If Artemis gets to Artemis 8, it comes down to below $9 billion average cost for each mission, factoring in the development costs. (Now, reuse of landing system hardware could bring the eventual costs down even further to something a lot more reasonable.)

Blue Origin is on track to be the second company to put a reusable rocket into service in the 2021-2022 time frame and one with more payload than anything that the rest even have in planning stages which are nowhere near fruition. Their engines run Vulcan coming online in a similar timeframe which would also be one of the more important rockets in that timeframe. BO looks like a joke next to SpaceX, sure, but can the rest of the world laugh? No, go do something better.

>>12317933
Rocket Lab will reuse an Electron before New Glenn leaves the pad

>>12317933
I kinda doubt we'll see BO reuse a booster until at least a couple years after maiden launch.

You're probably right, third then. All US-based companies.
>>12317943
Aside from Rocketlab with their parachuting smallsat booster and Vulcan with its retarded partial reusability, everybody who's pursuing reusability needs to solve the same retropropulsion issues. It will take trial and error, but it will take just as much for the rest of the world who are even further behind than BO is.

>>12317890
>(Now, reuse of landing system hardware could bring the eventual costs down even further to something a lot more reasonable.)

Does that account the 40B$+ needed for developing SMART recovery, it's running costs, and the need for a totally new VAB because the current one isn't tall enough to support bulkier engine module?

>>12317639
Yes the US must be entirely reliant on the patr- on the diverse and international public-private partner company ULA.

>>12317981
Sure seems like USAF saw BO and Bezoz as their out from sticking to ULA, but Benoz can't seem to get his shit together

The fuck is Bob Smith doing and how long before Benis finally fires him?

I watched an interview with CEO of Masten, and he seems to think the market is becoming saturated for small launch (obv) but also for in space transportation. Keep in mind these are the small moon lander guys. He teased there is one market that is wide open but didn't talk about it so as not to aid possible competitors. What market could he be teasing that fit Masten's business?

The next big opportunity outside of payload construction would have to be satellite busses, but that's already shaping up to be a crowded market. Maybe a bus with integrated landing functionality to make use of their R&D? Not sure how much of a market there would be for that.

>>12318012
lunar prospecting maybe? space manufacturing? I think buses partially fall under the transport banner.

That's not how orbital inclination changes work, either.
I think the original diagram with its blue line isn't showing the actual trajectory, it's showing latitude over altitude. Not an actual representation of the trajectory, but tells you the same thing, because it's basically saying "the ellipse is tilted so that we miss the worst parts of the belts"

>>12318075
He keeps it kinda vague so it's a little hard to follow but I like the practicality of what he's saying. He sees the writing on the wall in the launch market and smartly stays out despite having a working landing concept, and he understands that driving down payload costs is the thing to focus on now.
I think the bottom is going to rapidly fall out of the smallsat market over the next ~5 years just as all these guys are hopping on board.

>>12318208
smallsat launch market** should have specified. Smallsats as a concept aren't really going anywhere but when you can put hundreds of them on a big rocket and bus them into place with an individual contract price much lower than a dedicated launcher, it becomes a no brainer.

>It was later revealed that a potentially dangerous incident occurred during the EVA. Once Grechko was back in the airlock, Romanenko asked to look outside, so Grechko moved aside and Romanenko pushed hard against the airlock. He did not have his safety tether attached and began to float away from the station and thrash about. Grechko grabbed his commander by his untethered safety line and pulled him back in
WTF.

>>12318250
yeah...

>>12318257
>(In an interview afterward, he reported he asked Romanenko, "Yuri, where are you going?") Grechko felt the incident was overblown by author James Oberg to sound more dangerous than it really was. Although Romanenko's safety tether was not attached, there was still the electricity/communications umbilical that would have held him to the station. Another complication occurred when the gauges indicated no air was refilling the airlock. However, it was soon realized the gauges had to be faulty, and they safely reentered the station.[2]

>>12318267
All they have right now is a display concept and a partial spacesuit they stopped genuinely developing 10 years ago. Most likely, outside interest is dependent on completion of a functional prototype and the cost of developing functionality got too high after solving the easy parts.

because you also need to be able to put it on and take it off, so it needs to be able to go from loose enough to remove to tight enough to deliver the necessary PSI. The MIT patents are for a memory metal thread that gets sewn into the suit and constricts when heated, but they haven't really made any progress on a functional prototype in about a decade.

Yeah I can see why he hates that figure so much then kek. He justifies it with talking about volume and power constraints, but it's not as if any of that is unrelated: bigger vehicle means more mass, more volume, more spare dry mass for more or cheaper/more robust power, etc. The fact is small is bad in rocketry, period, but in the current world there's nothing you can do about it, you're limited by launch options.

No I'm pretty sure I was right. I just drew the orbit around earth wrong idk why I didn't draw it correctly. Better yet I don't know why I didn't just attach this image it explains its a lot better

>>12318407
What how the fuck will that work? Any example renders?

>>12317866
In my experience as a bong the worst are krauts, frogs and - probably worst of all - swamp germans who are unbelievably smug and always patting themselves on the back despite the fact their wealth is based mainly on the dumb luck of having large amounts of oil and gas spread across a small population. Other nationalities know their place, haven't let success go to their heads quite as badly or have managed to properly face what happened in WW2.

>>12318428
Does catching the Moon's SOI from ahead require more fuel? In KSP I think the minimum dV intercept always enters Munar orbit from the rear.

>>12318361
Wouldn't the body expand against the material anyway? And what about those artificial muscle fibres made from fishing-line that made the rounds some years ago? Those seem like a very good fit for this.

>>12317461
>AFAIK the moon is inclined so they had to burn up to it
The launch site is also inclined off the equator. Part of the reason they allegedly chose Cape Canaveral is because it has a similar inclination to that of the moon. As far as I know, they didn’t need to perform a significant plane change maneuver in TLI because they had directly launched into a properly inclined orbit.

>>12318443
I have no clue. I must admit my knowledge of KSP trajectories is fucking abysmal. If I want to do landings I always use cheats to edit my orbit into the body. What I DO know is that the Apollo program preferred this path because you get a free return trajectory in case your engine doesn't fire at the Moon so maybe it does require more fuel as you said, but they did it because of safety?

>>12318443
I think it’d require about the same dV to get there if you timed your window to hit it ahead instead of behind. The main reason they came at the moon from the front was to bleed enough energy to get (close to) a free return trajectory if the lunar orbit injection failed.

The whole "numbers don't lie"/"science doesn't lie" rhetoric is honestly disgusting and anyone who touts and considers themselves scientifically minded should feel ashamed.
First and foremost, politicians have been using numbers and science to lie since the beginning of time and I don't know how they duped anyone into forgetting this. And second, numbers don't lie because numbers don't draw conclusions and drawing conclusions from incomplete data is called a "theory" which must stand up to scrutiny and examination, not followed blindly because it feels good or because you're not willing to accept certain things as outside of your control. It's just a blatant excuse to paint the party's dogma as fact.

>He thinks there's any fuel or oxidizer but Methane and Oxygen onboard

>>12319086
Starship is only fueled by methalox.

>>12319086
Then what toxic fuels are you talking about, retard? Starship is purely methalox, early prototypes are using nitrogen RCS.
>oh no Starship might explode and pollute the nitrogen-oxygen atmosphere with nitrogen and oxygen

>>12319086
there is no other fuel onboard Starship?
I don't think they even have any other liquids, it's Tesla batteries, LOx and cryo methane all the way down

Sorry i'm retarded please ignore me.

Exploding pressure vessels are still bad tho.

>>12319110
there was not a single true statement
>>12319113
yeah, it's still 100 tons of thin skinned pressure vessels falling out of the sky

>>12319113
even oldspace is moving away from good old spicy orange and cancer juice for RCS, ULA's new Centaur V upper stage for Vulcan will use the IVF hydrogen and oxygen RCS that they developed for ACES

>>12319118

don't ever reply to me again

if starship's heat shield was compromised somehow and they couldn't fix it in orbit, could they do a complete propulsive landing after refueling? or are the tanks not big enough

OK BOYS WE GOT 30 DAYS TO GET THIS OVER THE TOP

>>12319130
That would most likely make the starship too dense to reenter safely. It would be easier to just evacuate it and leave it in orbit as a propellant de

>>12319130
>if starship's heat shield was compromised somehow and they couldn't fix it in orbit
That actually brings up an interesting point, with the bolt-on structure even in the case of a failure it's likely it would be easily repairable in orbit (I mean, as easy as it gets to repair anything in orbit I guess)
>could they do a complete propulsive landing after refueling? or are the tanks not big enough
idk what you mean by this tho

>>12319130
I don't know, nobody's ever done a completely propulsive entry from LEO so I have zero frame of reference. I've been advocating this for the NASA HLS Starship if they ever need to get it back for some reason.

>>12319142
>complete propulsive landing
so you know how you get to orbit, where you burn upwards and then slowly transition to burning sideways? do the opposite of that

>>12319142
>idk what you mean by this tho
to land without a heat shield you need enough fuel to do the braking job the atmosphere normally does at a much slower rate

>>12319130
Can 4ASS invent heat shield tape? Flexible enough to apply over cracks and exposed surfaces, durable at reentry temperatures, sticky-backed. Never go to space without a roll.

>>12319147
Yeah but that's what it normally does. I'm missing the part where the scenario actually makes a difference in this. Presumably you wouldn't want to do it with a refueled ship (because mass) so you would dump the excess fuel using the same process normally used for refueling.

>>12319153
Himalayan cheese expands into a light, thermally insulating foam when microwaved

>>12319166
no, the whole way down
they do not burn the whole way down normally, they use the atmosphere to slow down

>>12319149
Ah okay now I get what you meant sorry.

>>12319166
>be in orbit, 7400m/s
>burn 7km/s retrograde
>literally just fall straight down

>>12319176
I don't think Scott ever doubted the Falcon Heavy.

>>12319168
>>12319176

So is scottlet only acting as if he likes SLS to not burn any bridges or is he really delusional?

What if Branson is right and it's actually more cost effective to use a jet powered aircraft as a first stage?

>>12318626
I don't understand this resueable astronaut meme.

>>12319184
bro science is so fucking RAD how could you have anything as philistine as an informed opinion? go team humanity!!

>>12319185
then let him build one
you need an upper stage with >7km/s dv that's also reusable and can be slung under an aircraft, so good luck

>>12319185
>rocket takes off from the pad under turbine-power
Who needs reusable wings anyway, call it half a stage.

>>12319130
Depends on how compromised the shield is.
Since there is steel underneath it could take some punishment and survive like Atlantis. Though Starship will be entering the atmosphere at higher speeds and a different angle so testing/simulations are required before this option is seriously considered

>>12319185
Its not

>>12319201
what if we just launched faster and higher? you can get Mach 5 with a ramjet

>>12319229
okay, now you need roughly 7 km/s instead of more than that
I think mach 3 in a climb would be enough personally, and you might be able to do it subsonic in a single stage like Virgin Orbit is trying to do if you don't care about reusability

>>12319153
Look, I just sawed this fairing in half! And it re-entered without any trouble at all!

>1.4 Gt yield of Bennu
thanks, Scott

>>12319182
Fuuuuuck okay so do y'all remember that week when Elon went on a twitter tirade back in like July? The whole "pronouns suck," "coup whoever we want" thing? I have a specific memory of Hullo going into damage control mode. I don't remember if it was a tweet or a video but he for sure said "you know, I've never been an Elon fan boy, just an observer". If I remember correctly it was a video because I have a memory of him saying it while he has like 5 spacex rockets behind him on the shelf lmao. I'll try to find it

>>12319130
You don’t need to burn all the way. There were studies after Colombia which suggested it could have landed by extending its glide path

>>12316732
its was a terrible idea
but it was still an option

This stuff can take up to 1000*F, what if you just layer the shit out of it?

>>12319304
1000 F is chump change, anon

>>12319306
I know, but it's the highest temperature tape I'm seeing so far. We need something that can take three or four times that, minimum.

>>12319312
double that should be fine, anything that can survive ~3000 degrees should be more than enough

>>12319136
Approximately 0% chance this will work anon
I signed it anyway

>>12318978
Not trying

>>12317359
it just looks weird because it's flattened to 2D

>>12319319
This stuff claims to be good to 3000, what if you just slather some of this shit over any cracks/missing tiles? Repair equipment required: one tub and a putty knife.

Escapism is the most dangerous of all ideologies. The manchild dream of leaving our planet behind is what lets people rationalize destroying the Earth and ignoring the plight of the third world.
The super rich and their chosen followers escaping a ruined planet is starting to become a real danger. If we don't act now it might be too late. They're already lobbying for stealing more tax money the public desperately needs to fund their way out.
And no, they won't take you with them, /sci/.
