What sort of Ideological split could cause a solar system wide cold war?

Huh, in a setting I thought up, the cold war happened a bit later on when spaceflight was discovered. The commies lost, and was displaced to Mars, while the capitalists retain control of Earth. The Jovian colonies are split into two, with Ganymede going red and Titan going blue-aligned megacorp (but secretly trades with Ganymede). Pluto, Uranus, and Neptune were too far out for any permanent colony but a rotating crew of scientists a la Antarctica. And the asteroid belt is rife with pirates unaligned with both sides. All a gigantic and slightly smoking powder keg of cold war skirmishes.
and then the alien von neumann probes descend on Pluto, barreling their way through this powder keg and blasting every ship they come across to tinder

Isnt it kinda like that in Gunm:LO?
Venus is full of genetic tinkerers and bio engineers.
People in Jupiter are cyborgs and mind uploaders that are building a dyson sphere around the planet.
Mars is reich themed and in a middle of a 4 way civil war with each side backed by other major powers of the solar system.
Pluto is a harsh frontier and Earth is a mad max style apocalyptic wasteland except a floating city which a much more advanced and is the base of the space elevator. The other end of the elevator is another utopian like city.

Some emperor called another emperor's wife a cunt.

Look up Jovian Chronicles. The entire basis of the setting is a solar system wide cold war. The basic premise is that Earth fucked itself up so badly that it went dark and the colonies across the solar system were left to fend for themselves, they ended up doing fine and established various solar nations from Mercury to Jupiter, then Earth got its shit together and got back into the game and no one is happy about it because the solar nations are all fiercely independent and Earth doesn't like that.
And the setting was kept locked in a cold war so hard that the war game's metaplot started getting pants on head retarded as the writers bent over backwards to ensure the setting forever stayed in a cold war. Every time a major battle broke out with shit going down on the scale of colonies getting destroyed and millions of civilians dying, everyone immediately threw their hands up and shouted 'TRUCE' and all fighting immediately stops because god fucking forbid DP9 actually write a competent story.
Stick with the original green book premise and only the early metaplot it's fantastic.

Warning though, despite being lauded for its fairly realistic treatment of space ships and whatnot, it is still primarily a not!Gundam mecha game.

Normies and their social-democratic governments stay on Earth. Radicals and mega-billionaries leave it to create their own societies, and since they have most of the non-government money and ideology, they take the top 1% of smarts with them.

Earth doesn't like the brain drain or sudden tax shortfall, and stays salty about it while spacers preen over neo-communism, neo-reaction, or pure monetary pragmatism as superior alternatives.

Watch the Expanse.

Fucking Belter peasant.

>and the two moons of mars
These are barely the size of Texas, aren't they? I have a hard time seeing them as being fractured.

>a dyson sphere around the planet
What purpose would this serve.

ignite jupiter into a star?

As always, first post best post

I meant that they are each singular nations but like you said they're not that big and are in competitions with each other and the nations on Mars.

Seig Zeon!

Nothing, unless you turn Jupiter into a star (which is theoretically feasible).

A physics-inspired one.

What is Europe until the last decades ?

>we live somewhere different to those other guys

Heinlein has a bit of this, groundhogs (the 90% of people that never leave Earth) have no idea what life is like off-planet but they still attempt to control every aspect of colonial life. This leads to some really shitty laws and rules, and it also leads to every single colonized planet/moon in the solar system being at war with Earth at some point in time. It's usually a "cold" war up to the point that we join the story.

>Jupiter is hyper-capitalist cyberneticists, Saturn is highly socialist bordering on communist gene-splicers.
Gunm has the opposite actually, Jupiter is communist cyber while Venus is capitalist bio engineers going full survival of the fittest.
During the ZOTT, Jupiter bring a super robot with nano bullshit which is the result of all Jupiter collective effort while Venus bring a team selected during their own tournament.

Turning useless rocks into living space, I think.

I was talking about cybernetics vs bio engineering and the theme of each planet, not the political side.
But yeah.
And it's correct that the sphere is for living space. They used up Jupiter's moons except 3 that were already populated.

Spacer people will develop a very different society from earthlings.
Their society is going to start off with a small, rich and controlled population of only the most educated and prepared people from Earth. Most of them will be scientists and physical work will probably be automated, meaning social classes won't be like the ones we have in Earth.
The internet won't be so fast as to provide seamless communications between planets and their society will develop even more radically in that isolation.

Its not hard to see a conflict happening because both sides will certainly believe their way of living is the best. All we would need then is for politicians to use the other side as bogeyman to help keep their large populations with different cultures stay politically united, like they did in the past.

That assumes the colonisation was the result of some unified effort in the first place.
has the right idea, although there would likely still be the establishment of colonies by nation states (or regional alliances, eg. EU) as a matter of prestige.
This then leads to competing claims for easily accessible resources, with arguments about legal juristiction, possible "claim jumping", piracy , etc.
Thanks to human nature, anything other than a cold war would be an exception.

Belta loda always on top pa you earthers

Unfortunately, the sheer difficulty of extraterrestrial colonies would make total war between them impractical. Using currently existing technology, it takes about 9 months to just get to Mars, and going beyond that even longer. Assuming a hard sci-fi setting, more advanced technology could cut the time, but not by much. Mars has no biosphere of its own, no magnetosphere, no liquid water (although there's plenty of ice in the poles and some underground, but you don't want to waste that), an unbreathable atmosphere, etc. Only the largest and wealthiest sponsors would be able to support large-scale colonies (I'd put the population of an early Martian colony somewhere in the hundreds; any number more than 1,000 is a serious stretch). So, at least initially, any sort of Martian "culture" or ideology would be dependent on the sponsor(s) of a given colony. Things may change if the colonies become closer connected, but nationalism and nativism is still going strong even nowadays. And that assumes a relatively "free" colony; autocratic sponsors like China would want to tightly control who goes there and what they do, so ideological differentiation would be even more difficult.

Continuing the hard sci-fi assumption, anything beyond Mars is going to either be automated research stations or sparsely inhabited orbitals. Any sort of independent "culture" is unlikely; most people out there would be more focused on survival and research than politics or ideology. Think along the lines of Antarctica or the ISS rather than America.

In short, ideological differentiation between extraterrestrial colonies and Earth groups won't be happening for a very, very long time. And spending limited resources on sending fleets/troops that won't get to their destination for months would be a waste. So if any sort of conflict will develop, it will be on the colonies themselves (potentially supported by proxies), but full-fledged interplanetary warfare isn't happening.

Bruce Sterling's Shaper/Mechanist stories do exactly this.

The Shapers are genetically enhanced. They operate out of a series of bases in the rings of Saturn, from which the Ring Council manages a semi-fascist security state based on genetic house politics.

The Mechanists are mostly cyborgs, masters of computers and robotics. Their strongholds are in the asteroid belt, where the Cartels operate a kind of state capitalist system based on cybernetic enhancement.

Each side sees the other as inhuman abominations. War is not open (weapons that can threaten a habitat are taboo) but espionage, intrigue, claim-jumping, assassination, dirty tricks, puppet regimes, bribery, etc are all widely practiced to undermine and eventually destroy one another.

The Mechanists are winning until the alien Investors arrive. At first, humanity tries to present a united front, but both sides also try to cut deals with the aliens for technology. The Shapers have the better diplomats (so they think) and gain an early advantage. Then eventually things even out with both sides realizing that the Investors are playing them against one another. The pretense of peace is dropped and cold war fires up again.

Meanwhile, Earth went luddite after an eco-catastrophe and is a primitive global feudal world a la Ayn Rand's Anthem (odd because Sterling is a passionate Leftist). The early large O'Neil habitats are now backwaters, mostly puppet regimes to one extent or another to the two big factions.

There are almost no planetary bases. Towards the end of the series, there are attempts to terraform Europa and Mars underway. Alien embassies are incredibly important but VERY small and dangerous.

this is one I've been working on for sometime

moon colonies vs Mars and earth.

four of Jupiter moons have been colonised but are not treated the same way Mars is, they don't have a government and are just Mere playthings of the Megas.

the four moon go into a civil war Mars and earth is playing one side and the communist are on the other

cyberneticists Proxy war with Mercenary,

Space Coletivism X Planetary Individualism. Lagrangers have to cooperate very well inside a cramped space habitat. Planeters can afford the luxury of a natural biosphere. Tension comes naturally.

The ideology could be supported by environmental adaptations. The hollow-boned citizens of Saturn's rich phosporus atmosphere see themselves as eagles that should watch over those poor people which can't live without solids underneath them and rely on anything other than aeroponics. The mercurians, whose economy is based on watts and solar energy, disagree and have the gigawatt-scale optical phased arrays to contest it.

A disasterous memetic engineering intervention leads to a revival of the Brazilian Integralist Party memeplex, which advocated a non-racial and meritocratic military nation. Doesn't matter your genetic, percentage of artificial enhancements or planet, it matters what you can do for the Solar System. Of course, the Integralists know what's best for the system.

Even if everybody has democracies, there could be tensions when the "transdemocrats" advocate that all humans should also have net implants to vote all the time on everything instantly. Some bioenhanced chimaeras sapiens try to change the definition of "human" to escape this.

be honest
this is why mankind will nearly annihilate itself in the grim retardation of the far future

Science men made ape smart. Other human not like smart ape, but good human save ape. Now they fight but not real fight, just chest beating, stink eye.

Any.

The exact same set of things that have caused wars before, except a few centuries later and in spess.
