>CAPITALISM HAS POISONED THE MINDS OF ALL EARTHLINGS.
>Before we get into guidelines, however, we cannot emphasize enough how much we do not recommend communicating with Earth. Capitalism has poisoned the minds of of all people, infiltrating their subjectivities; the process of unshackling ourselves will not be easy. Avoid the news. Don’t talk to your loved and hated ones. Let’s face it, if you actually wanted to interact with them or capitalist structures, you would not have moved to Mars. Religion, race, gender, sexual orientation and all other identities will necessarily be redefined and recreated in a non-capitalist context - an overwhelming task that we cannot even begin to comprehend from here on Earth.

Fleet of Starships will be available across the interplanetary distances. The main constraints are engine power/efficiency and the fueling issues. Ships can be built in any configuration. Whether big or small, once engines are powerful enough. We could have delta flyer type "shuttles" that can carry humans between Moon/Earth, a decent Starship sized ships between Earth/Moon.

>>14639427
>Raptor 3 development will start “in a few months.”
Any specific reasons stated for this besides the electric gimbals (not sure about that, they'll need a way to recharge the batteries on Mars, adds another point of failure, it's bugged me since they started doing it with the flaps but I guess if they have if for those already might as well use it for the engines, too)? I guess either he really wants to beat BE-4 or the cooling (and possibly other) issues are still too large for good reliability/reusability. Otherwise I'd have expected a slightly slower upgrade process, get a few orbital flights in for data and then start the next upgrade, also rather block upgrades than a whole new generation, but that might just be semantics.

>>14639482
I think aerospikefags in his audience keep badgering him about it so he probably threw them another bone here. Or he's one himself.

Classic soviet engineering avoided mass autism. They had regular film cameras with rad-hardened film likely taken from US spy balloons that were shot down.

But that's backward. Realism in sci-fi peaked in the 80s and died in the 90s. Back then artists were machine nerds. Now everything is fantasy bullshit magic with superheros and women beating up men 3x their size because "shut up it's cool stop thinking too hard bro"

>>14639474
>It's weird that they had better optics that the US
i mean they're nice pictures but they don't compare to what surveyor had done before

>>14639485
This image is completely ignorant of older sci-fi.
you don't attempt to explain the technology that doesn't exist, TNG gets this wrong. When you can explain something as it exists in reality, you do.
But TNG at least did a good job at world building so you could believe it works.
Current year sci-fi is just fantasy in space, where magic just happens.

>>14639427
>”Saying you have too much thrust is like saying you’re too good looking” - Elon
Retard, every stage has an ideal TWR and it's entirely possible to have too much thrust. More thrust could enable you to take more propellant thus increasing the payload or delta-v but that's not necessarily the case due to structural limitations. Mooooooarrrrr throoost is just one of those KSP like memes that refuses to die. If thrust was that large of a factor outside of getting off the ground you would never see anything besides solids and liquid engines with awful Isp but high propellant mass flow. Reality is much more nuanced and the best upper stages actually have a TWR of <1 but that's not possible with Starship because it has to land.

>>14639520

Very few people, even on /sfg/, realize how far ahead of their time the Lunakhod rovers were

>>14639508
>>14639513
i mean there was a lot of future fantasy material but it wasn't like it was because the authors were unconcerned with realism. they were working for magazines that were trying to sell to as wide an audience as possible and they had tight deadlines too, a lot like tng writers decades later. compare arthur c. clarke's work when he was publishing pulp to 2001 when he got some creative freedom to work with.

>>14639510
Could Surveyor move kilometers at a time? Didn't think so

>>14639541
yes, that's how it got to the moon

>>14639544
It's still where it landed

>>14639534
I'm convinced Lunakhod 2 barreled through the lunar landscape purely to take the crown of most traveled lunar rover at the expense of doing much science
>>14639541
One of the Surveyors fired its engines after landing to hop over to a new spot IIRC

>>14639537
>i mean there was a lot of future fantasy material
I think you'd be hard pressed to find any of it that is even remotely as fantasy as what passes for a "sci-fi movie" today.

Those old sci-fi magazine illustrations certainly weren't peak realism, but I nevertheless view them as part of a trend in rising realism that was abruptly cut short in the 90s, when "computers" and "nano technology" gave writers/artists an excuse to claim literally any magical bullshit was ackshully technology therefore sci-fi. See: webm related. Or nanomachines in the metal gear solid franchise (which is a product of the transition I'm talking about, containing both semi-plausible mecha and absurd magic horseshit.)

>>14639551
>The rover (Lunakhod-2) had two speeds, about 1 and 2 km/h (0.62 and 1.24 mph).
>Opportunity's maximum speed is 5 centimeters per second (2.0 in/s) although average speed was about a sixth of this (0.89 centimeters per second (0.35 in/s)).
>180 meters per hour
man.

Thought I was getting Mandela'd here, but nope, you guys just can't spell. It's Lunokhod.

>>14639560
Is Marvel considered sci-fi? Also what about Star Wars? It doesn't have as much magic tech, but it pretty much has plain magic.

>>14639570
star wars is space fantasy

'Mueller! Mueller! Mueller!’ goes the refrain. 'A million deaths were not enough for Mueller!'

>>14639570
It's a technicality to get mixed into; correct spelling is Лyнoхoд (Lunokhod), but pronunciation has the first "o" as an "a".

>>14639570
>Is Marvel considered sci-fi?
According to netflix, yes. Ask for sci-fi movies and the media corps recommend capeshit. It's absurd, but evidently the flimsiest of pretexts for magical stuff having a scientific explanation is considered sufficient to call a movie sci-fi.

Take Harry Potter, unambiguously fantasy, not sci-fi. Insert a single scene where Dumbledore says "actually Harry, magic isn't real. it's all advanced science, but I don't have time to explain it now." That's all you need. Now the entire franchise qualifies as sci-fi. Absurd, but that's seems to be the state of things.

>>14639560
i don't keep up with recent stuff enough to say but i think it ebbs and flows how hard or soft people like their scifi.
>Or nanomachines in the metal gear solid franchise
that was just some horrid and lazy writing in a horribly written game after it was perfectly clear from the first three mgs games that nanomachines were NOT behind all the vampires and telekinesis and what have you

>>14639551
Surveyor 6 did do a small reignition and hop as a test of liftoff from lunar regolith, though it moved a total of 2.5 meters

>>14639599
I'm sure it's just a coincidence that almost all are currently ongoing or recently released. Or it's that you're not searching correctly.
>But muh conspiracy
Why would Amazon be advertising for Disney (competitor) or Apple (competitor) or HBO (also competitor)?

>>14639606
I didn't sort nothing, that's the default order Amazon gave me. They're showing people what they think people generally expect. The general public seems to accept and expect marvel shit when they're looking for "sci-fi". I'm using that ranking as evidence of a cultural trend.

>just a coincidence
An artistic trend that's been ongoing for years.
>conspiracy
Nobody here is talking about conspiracies. Computers, the dotcom bubble hype and nanotechnology gave the general public an excuse to fantasize that literally anything could be done with science. Artists included. Nobody is talking about lumernati conspiracies, there's no reason to bring that sort of language into this dicussion.

The absolute state of current entertainment, the worst are the /tv/ fags that say shit like "i know its bad but ill watch it anyway to talk shit about it" like if it wasnt the same thing. and those tv shows have a runtime of like 10 hours, imagine wasting all that time watching mediocre/bad content.
>inb4 "you are wasting time on 4chan as well :)"
at least people here talk interesting stuff, and ive learned a lot since i came to this general.

>>14639589
>that was just some horrid and lazy writing in a horribly written game after it was perfectly clear from the first three mgs games that nanomachines were NOT behind all the vampires and telekinesis and what have you
I generally agree with you, but Ocelot and Solid Snake both claim otherwise in the second game.
>"There's no such thing as a witch."
>"It wasn't magic or new age mumbo jumbo. Certainly wasn't your psychic talents."
(suggesting a distinction between magic and psychics?)
>"There's no such thing as miracles or the supernatural, only cutting edge technology."

...then Fortune proceeds to apparently demonstrate real telekinetic power and prove both Snake and Ocelot wrong. The whole thing is clumsy and ambiguous, but at the very least the seed of everything being technology was planted before MGS4 during MGS2. Psychic/telekinetic abilities is particularly a weird one, not just in Metal Gear Solid but across science fiction. Even in Asimov's robot novels. It seems like 20th century science-fiction writers were somewhat open to the possibility of psychic nonsense maybe being scientific. It's particularly common in Japanese sci-fi of the 80s and 90s (Akira, Serial Experiments Lain, Neo Tokyo), by which time it seems to have mostly died out in western sci-fi.

But I maintain that none of it is as bad as marvel.

Metal Gear literally has psychics and ghosts. I don't care what plot contrivances Kojima comes up with, but he knows how to make a story interesting.

There is no reason why Starship needs nine 230 ton-force engines unless they want it to be capable of launch abort and landing early in flight, otherwise the extra engines don't warrant the added mass. Prove me wrong.

>>14639485
You had me until Vanquish. Vanquish is fucking based

>>14639786
They need nine engines because some of them are tuned for sea-level and some of them are tuned for vacuum.

Define "need". Why was 3 SL and 3 vac engines fine before they changed it to 3 SL and 6 vac? The mass didn't increase as far as I know and each engine increased in thrust with the switch to Raptor 2

The most kerbal response, I love it. NASA would've arranged a meeting to whether or not have a committee approve or not the decision of conducting a 20-year-long study to investigate launch abort scenarios, so that it gets cancelled a few years later.

I might have if it wasn't lifting off at 3 am.

I'd just like to interject for a moment. What you're referring to as Orion, is in fact, SLS/Orion, or as I've recently taken to calling it, SLS plus Orion. Orion is not a launch vehicle unto itself, but rather another multibillion dollar component of a partially functioning pork system made useless by the SLS subcontractors, shitty designs, and Alabama river rocks comprising a gigantic scam as defined by the GAO.

Many taxpayers fund a small part of the SLS scam every day, without realizing it. Through a peculiar turn of events, the version of SLS which is widely mocked today is often called "Orion", and many of its victims are not aware that it is basically the SLS scam, developed by the SLS lobbyists.

There really is an Orion, and these people are seeing it blow up, but it is just a part of the scam they fund. Orion is the capsule: the payload in the system that allocates the government's resources to other districts that need pork. The capsule is an essential part of a launch system, but useless by itself; it can only incinerate astronauts in the context of a complete launch system. Orion is normally used in combination with the SLS boondoggle: the whole scam is basically SLS with Orion added, or SLS/Orion. All the so-called "Orion" debris fields are really distributions of SLS/Orion.

>>14639950

The real question is if Raptor can even be started up that quickly. Doesn't matter whether you could theoretically get away quick enough if your engine takes several seconds to reach full thrust and that's before considering pre-chill (MVac starts engine chill about a minute before stage separation, presumably that could be shortened, though) or how well the vacuum engines perform in early flight.

They actually have a fuckton of contracts and I'm surprised.

>>14640191

>>14640210
They have a bit of a niche because their LEO payload is 1000 kg which is a fair amount greater than most of the other small launchers. Still though, 15 million per launch? Bleh

>>14640228
They're also less than half the price of other LVs that are in the same weight class; Vega, Minotaur, and Epsilon all lift about 50% more but are pushing $40 million per flight. $15 mil isn't a bad place to be given the competition.

>>14640228
>>14640241
It's a market space that I can't see surviving, given the tiny demand for unique orbits for smaller payloads and Starship's targeted flight rates.

>>14640241
There are a few nuspace competitors like Abl's RS-1 and Relativity's Terran 1 which both have greater payload despite being 'only' 12 million.
>>14640258
Yes but the original shareholders probably made out pretty well as their company's valuation ballooned and now some poor idiot will be stuck holding the bag. It's a bit sad because the collapse of small-launch could damage other parts of the industry.

>>14639531
>every stage has an ideal TWR
If you build the engine around a rocket, sure. But the idea here is that you build the rocket around the engine, therefore there's no such thing as too much thrust. You just make a bigger rocket.

Printing tanks is just stupid, trying to re-invent the wheel

>In the early 1970s the US Navy looked at a submarine-launched manned spacecraft intended to attack Soviet spy satellites in the event of a war—the idea being that it could be launched from an undetected submarine, perform its mission in less than one orbit, and then return to Earth before being picked up by Soviet radar.
>The basic concept foundered on fitting the so-called “Space Cruiser” into a Poseidon missile tube aboard a sub: even a much stripped-down design was hard pressed to fit into one. Anything that could fit wasn’t even going to get to orbit on its own. There’s not a lot of detail available about this early phase of STAR, but one presumes that a submarine looking to send one into space would have to surface, and then have the sub crew remove it from one tube and place it on top of a warhead-less missile in another.
>Ultimately the Navy lost interest, but one part of the initial design lived on. The Space Cruiser was a very long, thin cone, taking advantage of work that had been done on the hypersonic characteristics of the MIRV warheads for the Poseidon missile—though much larger, the Space Cruiser would have encountered the same conditions during re-entry.

In what order will humans land on solar system bodies? I'm betting on 1 Moon 2 Mars 3 Phobos 4 Deimos 5 Vesta 6 Ceres 7 Callisto. Not sure about Mercury, maybe too much radiation, or maybe the poles could work. Titan would be my first pick at Saturn thanks to aerobraking, followed by Iapetus. Triton at Neptune.

Fun fact: Triton was believed to have formerly had its own orbit around the sun like Pluto and Eris, but was captured by Neptune after passing too close.

This is evident by Triton orbiting in the opposite direction of Neptune's rotation, and the lack of other large moons around Neptune.

Anybody else just randomly stops whatever they're doing and simply stares mesmerized at the Moon countless times every night? I just get so captivated by it, its beauty amid the night sky is something I can't help but feel enchanted by it, almost as if I were in love. It inspires me like a muse would do, invites me to dream of a brighter future as well as undergo a vast myriad of pure, human emotions. In spite of how terrible things might be, of how meaningless everything might seem, or how empty one might feel, whenever my eyes fall upon that white, faraway disk in the sky, at the end of the day I feel like everything will be alright, because there's always the possibility of a better tomorrow.

>>14640487
Mercury doesn't seem that hard to colonize, just hard to reach because of higher delta-v requirements than many of the other planets. There are permanently shadowed areas with water ice right next to areas that are permanently lit, enabled by the low axial tilt.

>>14640517
I sometimes look up at the moon in daylight to see the angle of the sun's shadow across it and ballpark my own latitude. If I were incredibly bored and felt like doing spherical trig I could get an exact value.

>>14640402
Rutherford and Delphin (Rocket 3 first stage) are both 3D printed. Larger engines aren't worth single cast printing but can use printed parts.

>>14639491
You're worried about charging batteries? You realize if we send people and they don't have electricity they will die, right? Either electricity is a non issue or the mission is outright impossible, therefore electrifying the components of Starship is a good idea as long as it doesn't incur prohibitive constraints in other ways.

>The real question is if Raptor can even be started up that quickly

It'd be way easier to use fission plants to desalinate seawater and water the desert.

>>14640488
Probably Titania because it's most dense plus has some smoother patches compared to the others. Either way they're all quite small so landing on them and transferring between them won't be that difficult.

With more understanding of weather patterns a space mirror could control the weather to a great extent maybe even disrupting hurricanes before they make land fall

>>14641036
I think the real potential is with solar shades, not mirrors per-se. Mirrors bouncing light into space, not onto Earth. We can solve climate change like this. With enough solar shades and greenhouse gases (got that covered, lol) we can fine tune earth's climate however we please. Solving runaway global warming becomes easy, but at what cost? You've now invented a thermostat for the entire world to fight over. Still, it's the only practical solution. Carbon sequestering is unworkable BS, and even if we cut emissions to zero today the course has already been plotted. Solar shades are the least environmentally invasive way of fixing this. Much cleaner than salting the oceans with bullshit and all the other geo-engineering proposals.

Furthermore this technology could be used to terraform Venus, into a second Earth. It would take centuries to complete, but so did many european cathedrals. Long-term projects are possible with the right social structure.

It's still only 3 km/s of dV to get off the surface and an additional 8 km/s to escape. Mercury would be a good spot for the production of colony ships or mining material to create a Dyson ring so we can yeet large interstellar craft and power whatever future technologies that haven't yet been conceptualized.

>>14641047
Yeah that be nice if I cared about climate change

so they managed to get a signal from Capstone after all

>>14640691
I don't think you can tell from video footage when the startup command is sent.

>>14641047
You think there will be runaway global warming even with low human emissions? I disagree. It would take tens of thousands of super heavy lift rockets filled with solar shades just to drop the average global temperature slightly and optimistically it would still take a few decades to complete. At that point you may well use SBSP to create methane and then pump it underground, large scale climate engineering on Earth will always be nonstarter due to all the conflicting interests.

It doesn't matter that you can replace the chamber if it still melts again the next time, though. You still need to stop the melting, especially if you want an actually reusable engine, not Shuttle-like refurbishable, even if the refurbishing is easier (but probably still not doable on Mars).

Dropping a nuclear melter needs a tether (will tear) and a laser needs insane power and can't get that deep. A laser on a dropped item will need an even larger tether. And it all can't survive long because Io'niggers wont stop spewing particles into the magnetosphere...

Why is it a meme?

I hear that's because there are now two different BE-4 models, the one they use on the Vulcan and the one that will end up on New Glenn

I get it from a money perspective but doubling the number of people you need to make the same engine is crazy

Nice "first stage"

>>14641986
Why stop there? Make it fly so fast it reaches orbit, ez

>>14641986
hypersonic planes are expensive and complex, specially when compared to just making a bigger first stage

>>14642005
It's not that easy.

That's what big rocket wants you to think

AIPAC is strong because of how much they spend on lobbying. This doesn't change the fact that younger evangelicals are getting less and less zionist by the year.

What if you use a really big balloon?

Telling people you're literally trying to cause the apocalypse because there's a two millennia old prophecy that requires Israel to exist tends to turn kids off, yeah

I do this in KSP to get off Laythe with a smaller lander and no refueling.

>hilarious name
I think you mean a cool name.

Does this correct the problems associated with air-launch?
