#6203K

[rocket-enjoyer]

Judging by your setting's name, I'm assuming this is set somewhat far into the future? Did we (humans) make it?

Oh yes, this is a fantastic question!

The name 6203K actually refers to the boiling point of tungsten (the reasons for that are... difficult to explain for now, I may get into that with a later post)

The setting has a wide range - its history splits off from ours only a few years from now, somewhere in the late 2020s, but it keeps going until the late 2300s. So here is a "short" timeline of important events:

Development of moon bases happens throughout the 21st century, first beginning in the 2030s with Artemis and the chinese space program. (They later fuse together thanks to some international treaties trying to prevent space warfare but that's a story for another time)

Venus and Mars are next. Venus is colonized by Russia/Neo-USSR in a fascinating display of totalitarian idiocy in the 2060s and fascist billionaires follow it up with a similar show for Mars in the 2070s. This is one of the key turning points in the lore and has a large effect on the future of the solar system and how nations in space interact with one another. (Ask me about this later! This is something I have thought through a lot)

The Socialist Venetian People's Republic (SVPR for short) and whatever hypercapitalist slave-trading billionaire's wet dream is going on on Mars both collapse on the very same day in the 2130s. (The collapse of Venus is only heard of a lot later though due to how insanely isolationist they were.) Venus is in total chaos and has a planet-wide civil war for the better part of the next century (Now that I think of it further I think I'm just going to write a masterpost of the history of Venus later, it's fascinating) and Mars's billionaires, after realizing they have killed 80% of the workers they depend on for their money and livelihood, give in to some of the demands of the few left over and form an actual country, join the United Nations and give independence to the asteroid belt and Ceres who form the Asteroid Belt Federation (There's a bunch to talk about with them as well, ask about it later)

In the 2150s there was a new trend among companies and investors promising a new "revolutionary step for humankind" as there sometimes tends to be (currently with AI), this time taking the form of attempting to send probes to other star systems. This quickly faded and was forgotten about. Though perhaps it should not have...

Nobody really knows who originally colonized the Jupiter system or when. The more conspiratorially minded claim it was yet another forgotten OO program (OO are fascinating also. I love them), some say it was the SVPR considering nobody really knows what they were ever doing during their whole existence, most think it was some of the original independent asteroid mining colonies in the Jupiter Trojans. They may genuinely have been colonized by several states at once who simply were not documented. Whatever the case, nobody had really heard from Jupiter until the 2170s with the sudden realization that it had resources everybody wanted more of, mainly volatiles. As several space states sent colonizers there, they discovered that Callisto and Ganymede were already somewhat populated. With a few more colony constellations ("fleets" as some less autistic scifi writers would call them) sent, this time armed, the situation got a whole lot more interesting. Turns out people sitting on giant dull ships for years on end armed to the teeth tend to get some pretty revolutionary ideas. They all announce their mutual independence as they reach their destination and so the Jovian Moons' Republic is born. The colonizing states are baffled but understand that this was obvious in hindsight and, since they have not dealt with such a situation before and their military constellations and doctrine are not cut out for this, reluctantly accept JMR's independence.

Hmm, our space telescopes are detecting something odd around Barnard's Star...

The beginning half of the 2200s is pretty devoid of any major singular events. However here are some slower changes:

The Martian Republic (formed after that civil war in the 2130s, remember?) gets more corrupt and deregulated and starts looking more and more like the original colonies first set up there in the 21st century.

JMR gets stronger economically and militarily and becomes the leading power in the solar system. (Unless you count Earth, sort of?)

The many many factions of Venus who still hate each other are starting to do diplomacy rather than simply shooting each other to bits all the time.

Europa and Io are colonized by JMR.

Now, back to the big stuff:

In the 2260s the JMR, at the time led by the populist Jovian Might Party, decides to colonize the Saturn system. Why, you may ask?

...

Anyway, the colony revolts and becomes the Saturnian Demarchy because turns out space travel in the outer system is dreadfully boring and they're too far away for the JMR to really have any reasonable threats on the table.

The JMR reflexively declares war and (after a week or two of politicians yelling at the top commanders of the space force who are desperately trying to explain that this is a bad idea) a pretty hefty fleet of military ships and those same top commanders are sent to Saturn.

They revolt. Of course. However, instead of simply becoming part of the Demarchy, they decide to form their own faction, the Saturnian Militocracy. The name should be enough for you to tell that this is hardly a functioning country and is instead a military attempting to masquerade as one.

The Demarchy and Militocracy are locked in an endless war against each other and it's horrible. But at least the Militocracy made a cool ass helicopter. (Ask about that too)

Barnard's star is periodically dimming. Hmm.

The miners and engineers on Io strike and riot for better conditions at the very beginning of the 2300s. The JMR, whose military is still severely weakened and underexperienced due to the whole Saturn debacle, of course begins a long and painful military campaign to get them back to work by force. Eventua-

Immense aurorae are witnessed around every atmosphered body in the solar system.

Most of the old, young and sick die in under a week. Everybody else gets sudden health issues which get worse and worse until they die.

The great vengeance has been enacted.

Six tremendously bright lights appear at the edge of the Oort cloud, though few are alive to observe the data from the telescopes anymore. Two spacecraft of monumental size screech to a halt from near lightspeed and enter orbits around Neptune.

They search for any signs of humanity. Signals are being sent from somewhere around Io. Perhaps some were protected by Jupiter's magnetic field?

They cannot enter a close orbit around Jupiter. The radiation risks damage to their fleshy insides. They blast Io with what they have until the signals stop.

A new age in the solar system has begun.

I have been trying to design spacecraft for 6203K but as it turns out space is hard.

i should make some posts about my scifi setting i think

Well, I just love everything about this! I’m a big fan of sci-fi that stick to our solar system and it seems like you’ve got some good stuff here. Generation ships have been something I’ve been focused on for a while.

If I may ask—how are things on Earth?
