What would a Soviet Starship look like on the inside?

>>12759068
>What would a Soviet Starship look like on the inside?
as utilitarian as it had to be. as decadent as could be afforded.

>>12759032
It's a shame Berger doesn't elaborate whether that is for the early vehicles or a general statement. The first versions of any rocket are going to be horribly expensive, even more so when the flight rate will be like 1 a year for a while. BO has the other issue that they are setting up an entirely new production line, so they have all these additional costs plus development. It will be far more expensive than its competitors. Also if they go all in on reuse, then the stages they do produce will be more expensive because of fixed costs.

>>12759068
Offwhite and green cloth everywhere with stains and tears, tubes running all over the place, dim lighting, Orthodox icons on every doorway, the slight odor of UDMH in that one room

For You.

>>12759072
I’m sure New Glenn is overall a more expensive rocket than most. It’s huge as shit and uses isogrid construction (I think). Also it’s second stage is the second largest hydrolox stage ever created, and uses two engines. I think their switch to Hydrolox for the upper stage was to save time, but they should’ve stayed with the methane upper stage.

>>12758979
Would it be possible to build a plasma pulsejet that could accelerate a craft high enough to switch to internal gas supply for spaceflight with a compact generator of a few kilowatts?

>>12758983
No one will actually be a permanent colonist, just rotating contingents of terrans. Any attempts at rebellion are squashed so much easier outside Earth-like conditions.

HOP MONDAY

Has anyone really been far even as decided to use even go want to do look more like?

>>12759168
Yes

>>12759026
>implying it's not just old and stained

>>12759143
Yeah it's basically a ULA rocket but built bigger than any ULA rocket ever was lol. They don't have the ethos of "do it as cheap as possible". I think the BO management fell into the Musk meme of "reusable automatically means we make all of our money back" without realizing that that's half the fucking battle

>>12759166
You're the equivalent of a peon or at most a craftsman saying "when we sail to the new land, the crown won't be able to do anything to us!"

>>12759143
I never realized how small the ubiquitous centaur upper stage was until someone pointed out the F9 upper stage actually has more d/v. BO's bigass hydrogen stage is going to be ridiculously expensive, and then they're going to throw it away. It's a mess of a design choice.

>Musk has used the medium of dreaming and exploration to wrap up a package of entitlement, greed, and ego. He has no longing for scientific discovery, no desire to understand what makes Earth so different from Mars, how we all fit together and relate. Musk is no explorer; he is a flag planter.
SpaceX Debunked?

>>12759188
The crown couldn’t effectively put down the American Revolution once the French navy got involved because it took ~3 months to deliver troops and supply them
Once Mars has sufficient anti-spacecraft weaponry, it would be real hard for any earth army to establish itself or effectively put down any military resistance

Out of all the analogies to demonstrate how mars won't become independent, you choose an example from a country that ended up becoming independent?

>>12759215
Who sponsored this hit piece? Reads like something from Bozo's blog.

>>12759208
Yeah, except Mars is not a cornucopia where you can just build a hut out of shit and tree trunks and call it a home. And the metropolis doesn't need to send thousands of soldiers on hundreds of ships. They just need to make the orbiting spacecraft that were there from before the colony proper was even started glass your surface access and then play whack-a-mole for a little while as you try to dig out until boring machines bearing nuclear charges are delivered from Earth.
Or the scorched earth scenario of crashing enough meteors until everyone dies of marsquakes if you really piss them off.

>>12759215
>Heh why don't you fascists just leave then?
>HWHAT NOOOOOOO YOU CAN'T JUST LEAVE
literally I do not understand.

>>12759185
Yeah Falcon 9 is cheap as shit anyways. That’s why reusable rockets owned by governments (VentureStar, the Shuttle, etc) will never work. Because they're expensive right off the bat.

>>12759192
Centaur is tiny yeah. I can’t believe Blue fell for the Hydrolox meme. The only other Hydrolox upper stage that’s bigger is the S-II on the SATURN V and blue thinks they’ll be commercially viable

>>12759218
>Once Mars has sufficient anti-spacecraft weaponry
So never, because it will be terran anti-spacecraft weaponry.

>>12759215

Except we don't. We want to explore and you don't fucking get that.

Oh and she's comparing Sagan to Musk but she doesn't understand the difference between them. Sagan was a person who inspired people to do things, Musk is a person who does things.
Sagan was hoping for people to do things, if that old pot smoker was alive, he'd be grinning like a motherfucker at SpaceX today.

He would not be writing "oh no we can't go to Mars because that'd be racist and capitalist" articles, he'd be saying "awesome, let's go".
You can't fucking explore without being there to plant a flag.

You know, I absolutely despise anime and call those who indulge pedos, but I don't think I could ever write a comprehensive hitpiece on anime pedos. I just dont care enough. What exactly has got her so absolutely seething? Why does she care what people's dreams are??

>>12759255
Sagan and Zubrin are similar in that both really had no power except to get others to dream

>>12759228
Of course. Because the brainlets would bring that shit up immediately, look at the first fucking reply. They don't understand that the parallels end real pretty much at that point. There are no vast swaths of habitable land to run away, hide in and sally out of. You lose your air regenerator and you are fucked. You lose your water regenerator and you are fucked. You lose your hydroponics or whatever enclosed fragile biome you rely upon for food and you are fucked.
Then you have the issue of the metropolis needing literally one guy in orbit commanding the anti-ground satellite network. You retards fail to understand that the metropolis will be there second, right after the pioneers. The pioneers who will depend 100% in pretty much everything for at least decades on the home planet they are so willing to spit at. And because of ooga booga I throw rock the metropolis WILL get there and maintain military presence controlling and directing everything. You've made your bed, now lie in it. I want to say that you could have prevented this but human nature is human nature.

I grew up Cosmos back in the 80s. Shit pretty much made me who I am, which I am very thankful for.
They don't make stuff like that anymore.

Listen up anons, the prophecy goes as follows:
• Currently, there is a political ideology that is openly against manned spaceflight and colonization
• We will get to Mars regardless and create a colony, and there is a high probability that it will turn into a self-sustaining city with huge economic opportunity
• The same people who are against it will then flock to it in the future (only after everyone else has busted their ass to make it survivable of course) and they will try to institute THEIR way of life and their rules
I'm willing to accept Mars as a possible loss. It will be cool for a while but it will turn into the reddit planet very quickly. How do we prevent the downfall of Titan though? I saw we colonize it early, set up a lot of opportunity of trade with Mars and the Earth-Moon system, BUT we institute extremely regulated migration and entrance rules. Unscheduled landings or visits to our Moon will result in you being shot out of the sky. Political treasonists will be thrown into the bottom of the methane lakes.

>one guy in orbit commanding the anti-ground satellite network
Get a rocket on a mobile launcher with a bunch of grapeshot in the warhead at the orbit of your enemy and you fuck up the entire system, the defender only has to win by making it too costly for the attacker, the attacker has to occupy and hold an entire planet while keeping civilian infrastructure intact to maintain a grip over the planet

>>12759290
Oh, so you think only Spain and GB ever sailed across a large body of water to make a colony. Never thought /sci/ can be this retarded. The analogy, not AN example, was vague enough that only a few triggered american retards immediately thought it is about the US. It's just you who can't read well, it would seem.

Does anyone genuinely believe that we'll be seeing SN10 flying within the following 3 months? You'd have to be deluded beyond salvation, i mean, TX has an energy crisis going on, and strongly at that too, so there's no way resources will be diverted so that SpaceX can go for their usual performance. That's right, a performance, it's nothing more than that. The concept of Starship is immensely flawed, it'll never fly officially, be it carrying people or cargo. It's an entertainment venue. A marketing stunt. It's a deranged manchild's wet dream. It's his little fantasy of sending shit upwards and then blowing it up. He's a child. A loser. All of you who cheer him on are losers too. Space should be left to those who've dealt with it thoroughly, through known and extensively-tested tech, so that We, the Human species, can explore the farthest reaches of space with minimal failure probability, and maximum data intake. Quit grasping on to moronic concepts, believe in science instead.

You should care because even this literally who has some 30k followers on twatter, and there are thousands, maybe tens of thousands just like her. It's easy to just pretend that these people hold no power, but they're ultimately an influence on majority opinions, both in the general population and among policy makers. Make no mistake, the commercialisation of space flight will be seriously impacted by these people.

Sure, you can can shit to make a year's worth of supplies. Maybe for two. Do you think you can outlast machines? It's not the XIX century, you don't need "civilian infrastructure" to keep someone in the stone age if they are living in a sealed cave under a wasteland. We have drones blowing up towelheads most likely as we two communicate.

>Get a rocket on a mobile launcher with a bunch of
I really didn't think it is worth replying after this part but the other one gave me a tiny and most likely last impulse:
>the defender only has to win by making it too costly for the attacker
You truly don't see the fucking irony? Of considering the effort of clinging to a dead rock with not even a breathable atmosphere and uncertain chances of producing offspring without fucking centrifuges lesser than one of sending drones to fuck your shit up on the very Starship design that have been used to make your sealed caves under a wasteland a reality?

All one has to do is get enough shit flying fast enough to kill everyone on board and fucking up your orbital bombardment system for months at the very least, and likely launch retaliatory bombardment strikes by starships aloha snackbaring into cities or military targets, which is far more vulnerable to attack than a martian bunker/hive city

The point is it takes Earth fucking months at least to set up a bombardment system that would be taking fire the entire time and be far too expensive to be worth such an endeavor
There's nothing worth Earth taking military action against a mars wanting political independence and if they did, they would get fucked up to the point the political machine would declare it not worth it

>>12759483
Yes, I’ve considered the ethics of leaving the degenerate West—where children are raised learning it’s okay to chop their dick off and kill their children if they get pregnant. Fuck the elites.

The fact that Sanders, a literal outspoken socialist, was even a serious contender for the dem primary speaks volumes of their influence.

>>12759529
>Sanders
>Serious contender
This is what I mean. Sanders lost disastrously in back to back primaries, even with 4 years of national attention. The only reason you think he was a "serious contender" is because you get all of your news and media from twitter and reddit. Get offline, actually look at election results, and you'll see a much different world then the one twitter losers live in.

This is what Lockheed Martin actually did

>>12759706
Oh shit.
It's gonna hop next week and stick the landing except it'll come in just a bit too hard, the legs won't be able to handle it, and it'll still destroy all three raptors and it's bottom.

>>12759728
>
The larger the vehicle the better, this goes for fusion torch drives even moreso than any other rocket, because the stupendously efficient drive requires a comparatively low reaction mass/vehicle ratio.

>>12759735
To be fair: this idea was around before starship, and also it's easy to compare it to SS because of the way it looks but a more accurate interpretation would be "this is a lunar lander on steroids"

>>12759745
Oh man I love this drawing. Iterative design is great. It’s too bad that things take a decade to build now.

>>12759738
Lol I'm taking bets that they have ANOTHER engine problem somehwere and it smacks the concrete again. What else could go wrong now besides not enough fuel, and failure to light?

>>12759752
An engine could fail on ascent. I’m scared of that

>>12759696
>everything checks out, light 'er up

>>12759749
They proposed it to NASA early, before they were even taking Artemis lander proposals. They also offered to skip the first one and go straight to the heavy-landing, fully reusable second design. In classic LockMart fashion they were turned down by NASA despite having a based proposal. It has the "safety" of an oldspace lander like NatTeam, except it is actually pretty cool. They always get cucked in favor of other oldspace people

Yeah RIP the big lander I remember it. I remember they scaled it down and asked again but NASA still said no. LockMart obviously is full of dreamers but sadly the higher ups aren’t them.

>>12759745
>To be fair: this idea was around before starship
Not really. SpaceX's ITS was unveiled in 2016 but the idea of 100t vehicle was announced back in 2014. Lockheed ship design unveiling goes back to 2017. Well after ITS presentation and all. Its a direct response to SpaceX's ambitious goal.

>>12759764
Ay, you ever been fucked by Karma, lad?

>>12759772
What part of putting memey shitpost names implies confidence and assurance of success?

>>12759768
If we lived in a world where SpaceX didn’t exist I’d be more inclined to be excited for LockMart’s vehicle. I always thought a dedicated but reusable Ascent/Descent vehicle was the way to go. You refuel it on the surface and then launch it to orbit. In orbit you load cargo and it then lands back on Mars where it can be refueled.

LockMart’s lander has the advantage of requiring far less fuel than Starship. It only needs 70 tons of Hydrolox. It still needs like 11 or so tons of hydrogen though

>>12759774

>>12759776

it is. gravitywell craft and interplanetary craft are two different things. we only try to combine them both now because of the infancy of spaceflight and cost. fight me all of you.

>>12759790
Starship only needs like 800 tons of propellant to carry 100 tons from the surface of Mars to orbit (and back). That’s a huge save.

>>12759792

>>12759809
Wtf anon that was Elon!

>>12759797
it's optimised for gravity well flight. it will be a huge compromise and an ultimate dead end for interplanetary flight. it's a shuttle. future generations of it will dock with larger ships built in orbit whos design never intends them to come near an atmosphere.

>>12759772
No, because I never remember when I do something overconfident, I forget about it and if something goes wrong I deal with it instead of thinking it was somehow destiny.

>>12759825

Nuclear-electric is close to optimal if you can get the specific power and the thrust high enough.

>>12759925
Conveyor belts in space, I like it

Need more funding for space telescopes. We are so close to actually being able to figure out the chemical composition of exoplanets and their atmospheres. Even continent sized features, as well as exomoons and yes even ayy mega-structures or pollution could be detected with a telescope large enough.

Monies from SLS program should be able to fund several JWST type telescopes or possibly a single megatelescope.

>>12759992
If Biden cancels SLS conservatives will prend to have loved it all along and it's a terrible loss for humanity

>>12760013
we can't wait for several jwst telescopes, they aren't designed to look at the universe when only photons exist.

I wish SLS was called the Space Crew Framework (or something else that makes an SCF acronym) so we could call it the Sunk Cost Fallacy rocket

good. thew government doesn't need to be wasting hundreds of billions in taxpayer money to build overly expensive rockets. let the private sector do this shit, let NASA subsidize and provide expertise when needed

they have, otherwise there never would of been a single hop

>>12760021
Even without cost overruns JWST would be unacceptably expensive if one cares about practicality. It would be much more practical to build many scores of less powerful but much less expensive telescopes and network them together to create a very large virtual objective lens, rather than actually build an ever increasingly impractical giant reflector. Build a hundred telescopes which are individually only a tenth the power and a tenth the size, deploy them as an organized swarm using vehicles like Starship or Vulcan, massively reduced expense, massively improved redundancy, massively increased resolving power.

No. The Ares program was nuked - because it would take too long and too much money to send anything in orbit - and the SLS was born as means by congress to fund strategic jobs during economic crisis. By reusing the Ares program and all its contractors, and contracts, so that there's no need for messy new legally binding things that might let someone else get part of the money.

What do you think about this company? They’re trying to make upper stages reusable. This seems hard because you need to handle several km/s reentry speeds. Also, you’d need to make a tough design decision: be primary stage agnostic to be able to be slotted onto any rocket system or be launcher-specific which hitches your fate to the launcher’s.

Not really, the SLS was an Obama appointment and its hard to get the senate to cancel a program just to restart a new program for the same purpose

>>12760164
Same senator who canceled the Lockheed's CEo for wanting to pursue fuel depots over the SLS?

Interstellar travel is possible man. Fusion aside we can get to Alpha Centauri 100 years from now if we started building an Orion drive ship.
> Later studies indicate that the top cruise velocity that can theoretically be achieved are a few percent of the speed of light (0.08–0.1c).[20] An atomic (fission) Orion can achieve perhaps 9%–11% of the speed of light. A nuclear pulse drive starship powered by fusion-antimatter catalyzed nuclear pulse propulsion units would be similarly in the 10% range and pure Matter-antimatter annihilation rockets would be theoretically capable of obtaining a velocity between 50% to 80% of the speed of light. In each case saving fuel for slowing down halves the maximum speed. The concept of using a magnetic sail to decelerate the spacecraft as it approaches its destination has been discussed as an alternative to using propellant; this would allow the ship to travel near the maximum theoretical velocity.[21]
>At 0.1c, Orion thermonuclear starships would require a flight time of at least 44 years to reach Alpha Centauri, not counting time needed to reach that speed (about 36 days at constant acceleration of 1g or 9.8 m/s2). At 0.1c, an Orion starship would require 100 years to travel 10 light years. The astronomer Carl Sagan suggested that this would be an excellent use for current stockpiles of nuclear weapons.[22]

I'm getting really sick of people defending the Obama administration's actions in regards to NASA

>>12760334
Well you’re a chud so I’m right and you’re not

>>12760331
>36 days at constant acceleration of 1g or 9.8 m/s2
Orion can't accelerate that fast.

>stop acting like one side is somehow anti space
Biden has a horrible track record for space so you can cut the shit

>>12760341
? It can take off from the Earth, of course it can

>>12760341
10 years of accelerating at 1 mm/s^2 will get you to 10% the speed of light. You don’t even need propellant to slow down just use a mag sail and your trip is already 50-120 years, what’s 10 more?

>>12760351
Not one large enough to travel to alpha centauri.

>>12760351
nothing you're sending to another system will need to take off from urf. you do that shit in orbit.

>>12760361
It’s easier to build on the Earth than it is to build in orbit... unless you are talking about some magic indefinite future where everything is cheaper in space...

>>12760334
It's just typical "anything bad that happened when my team was in control was the other teams fault"

>>12760367
It was estimated that an Orion ship capable of reaching 10% the speed of light would have 300,000 tons of nuclear bombs, a 50,000 ton structure, and 50,000 tons of payload.

>>12760337
K

>>12760367
We're already talking about some magic indefinite future where interstellar travel is not only possible, but desirable enough that people would spend their entire lives in the void, never return again.

>>12760375
Sounds way undersized like most Orion designs
You need to be big enough to make fission-fusion pulse units viable

>>12760367
it would be easier to build in orbit. nothing of the size needed would be launched from earth unless we've just made anti gravity.

>>12760378
Bruh that’s pretty much what we plan on doing with Mars. I’d definitely go on an interstellar trip. If Elon said tomorrow “hey we’re building an Orion vehicle to get to Alpha Centauri it’ll be done by 2040.” I’d be about 90 when it reaches the star.

>>12760378
>but desirable enough that people would spend their entire lives in the void, never return again
so like the 2070s

>>12760371
Yeah which is frustrating especially here and we need to be critical of everyone especially the "party of science" when they hurt scientific efforts.

>>12760385
You're a fucking idiot and you don't even know what the plans for mars are. Yes, Martians can come home if they feel like it.

>>12760397
>if they feel like it

>>12760397
>Martians
>can come home
home is mars. it's a one way trip for our lifetimes.

>>12760400
>if

>>12760397
Yeah but I’m okay with that. I’d love to spend my last years on another world whether it be mars or Proxima b

We’re learning about the early Paleolithic period in Biology at my Uni. Anyhow I was thinking of how it mirrors our situation with space colonization. The first humans in Africa lived in their single environment until one day they decided to check out newer areas but still on the same geographic location. Then one day the voyage across the continent and into Asia, Europe, the Americas was made. It took generations and no one who began the journey saw its end, but eventually there were people all over the world.

Our first step into a new geographic location will be the colonization of Mars. But we’re still confined to the African continent (the Solar System). We may spread across Africa (the Solar System) but we’ll be stuck here. One day someone will make the trek to another continent (extrasolar planets). I don’t really know what I’m saying but this prehistoric human stuff really gets my feels going.

>NASA says that the assessment of Boeing's safety culture, ordered in the wake of the flawed OFT-1 mission, has been postponed until after OFT-2 because of Covid. That’s a delay of more than a year. The agency says it will complete the review before Boeing’s crewed flight test.

Does anyone have space-related book recommendations? I would like to learn more about space flight in general.

sorry to be cunt here. but how? how developed was man at this point? boats and shit or what happened?

>>12760476
If you haven't already "The Space Shuttle Decision" is required reading to truly be able to seethe at the Space Shuttle with any sort of authority. I'm pretty sure it's free to read on NASA's website.

>>12760475
it's over. you can't fly a prototype for a commercial contract 2 years after the competitor fulfilled and expect to carry on.
or can they?

>>12760475
This is the sorta BS you have to deal with when ur a government contractor
Random year long delays and outside “reviews”

>>12760477
on foot, through land bridges during ice ages

>>12760477
People literally just walked into Asia and then into Europe and then crossed a land bridge into the Americas. It took like 50,000-100,000 years it’s insane. I can’t imagine being born somewhere in Siberia and spending your whole life crossing a few hundred miles of frozen wasteland to enter the Americas. Australia and the pacific islands were colonized by people making boats. This is surprising because no one knows how they crossed thousands of miles of oceans with 100,000 year old tech. Maybe thousands tried and failed but enough made it to start a pooulation

>>12760378
earth is kinda gay t/b/h I'd spend the rest of my life in space even if we were just circling around
