2044 – Artemis 11: First Successful Manned Mission to Mars
2078 – Beginning of first U.S./German led Lunar Colonization Experiment
2091 – Lunar Colonization Experiment Fails
2096 – Companies and Governments Salvage infrastructure from failed Lunar Experiment and form the underpinnings of Luna Station
2133 – U.S. and Chinese Scientists create temporarily stable Terran Conditions on Mars' Poles
2136 – USSCE launched, spearheaded by China and US. Beginnings with large scale Terraforming effort on Mars.
2186 – After half a century, Martian Ecosystem Stabilizes, habitation rapidly expands
2262 – The "Rubicon Act", formally the International/Interplanetary Act for the Prevention of Technological Disaster, signed and put forth as an addendum to regulations held by the USSCE. The Rubicon Commission formed in 2265 to enforce it.
2275-2280 – The Mercurian Civil War.
2325-2360 – Ice Age of Expansion. Titan colonized and "tundraformed" in 2325 and capital of Hotei in 2327. Many space stations and network waypoints set up out to the distance of Saturn's orbit and just beyond. An outpost is set up on Triton, but contact is lost.
2372-2385 – The Secret Renaissance: Scientists undertake secret research in violation of the Rubicon Act on Galilean Moons.
2385-2388 – Escalation: The Rubicon Commission discovers Galilean activity and heavily sanctions Galilean Colonies. In response the Galilean scientists switch their research to extensive military development in preparation for a declaration of independence.
2388 – The Galilean Union declares its independence from human colonies following the Rubicon Act. Governments of terrestrial colonies pool their military resources to give the the Rubicon Commission enforcement power. The secret Galilean military responds by launching attacks in the Greek and Trojan asteroid camps and quickly overrunning the RC presence there. This is considered by many to be the beginning of The Galilean Wars.
2390 – The Terran Federation forms among all non-Galilean colonies as in the effort to create a force capable of bringing the GU back into the fold, or, if necessary, destroy so much GU infrastructure that it will no longer be a threat to humanity scientifically. Earth is considered the center, with the seat of government inside Luna. The sparse colonies on Venus do not honor this new government, and while extra-Jovian colonies do contribute troops to the cause they only do so grudgingly.
2398 – After helping the inner TF to fight the GU for half a decade while also being cut off from crucial resources, leaders in the extra-Jovian colonies agree to secede from the Terran Federation and form The Outer Free States, a third government with an officially neutral stance on the war. Many soldiers return home, but a strong mercenary presence remains behind.
2405 – The Bombardment of Callisto and The Massacre at Sun-Earth L4. These two attacks each result in massive civilian casualties and damage to infrastructure and weaken motivation, causing both sides to consider peace pursuits.
2410 – The Solar Peace Pact signed by all three nations, but not ratified by the OFS. The Terran Federation grudgingly allows the Galilean Union to continue it's pursuit of formerly forbidden sciences, but enforces the Rubicon Act within it's own borders. The TF establishes The Tycho Group, a secret arm of the Rubicon Commission meant to monitor the activities of GU scientists.
2410-2452 – Pax Solaris, or the Rebuilding. In spite of the existence of organizations such as the Tycho Group, the first half of the 25th century proceeds in relative peace. The TF takes this time to reestablish its infrastructure, including building a new series of habitats with more effective defences at Sun-Earth L4. It generally improves it's defenses and mass-produces an effective and nigh impenetrable military shell around its core colonies. The OFS simply seeks to establish a sustainable infrastructure, which it accomplishes through trade with the other nations. The GU fast-tracks itself to a "technological utopia" and likewise establishes powerful defenses, but for the most part ensures that it won't be attacked by guaranteeing mutual destruction should the TF ever impose itself again.
2452 – Tycho Group surveys reveal that Galilean scientists have discovered how to imprint and replicate consciousness-states, effectively beginning the Age of Transhumanism. TF propagandists make the work public as an affront to humanity. In response, the GU prematurely advertises the technology as a grand achievement.
2452-2461 – "Geisterzeit": The GU aggressively pursues transhumanism and many rush to download their consciousnesses, but the procedures are costly, and attempts to cut-corners coupled wit the immaturity of the techonology lead to many botched attempts. Many downloaded consciousnesses go insane, backfire in their second bodies, or become free consciousnesses roaming the Solar Web. Tycho Group agents almost entirely quarantine these "nomads" in the Galilean web but a few bleed over to the entire systemTerran Federation threatens military action if Transhuman projects don't cease. This time, the Galilean Union complies, as their own information networks have already been rendered unstable by the presence of nomads.
2485 – Tycho agents learn that a derelict Galilean space station, the SHGU Al-Basri, was dicovered by OFS rangers floating between the Uranian and Saturnian orbits. The onboard AI is insane.
2488 – The Centennial of the Galilean Declaration of Independence. Confident that they will execute it properly this time, the Galilean High Council reauthorizes Transhuman downloads, but not directly to the Solar Web.
2489 – Terran and Galilean threats escalate over new tech issues, but peace activists on both sides try to prevent war.
2490s – Tensions over Galilean projects have resurfaced, but no faction is willing to launch a total war for fear of massive civilian death and loss of infrastructure. This opens the door for many mercenaries, hackers, pilots, explorers and freelance investors to work as "contractors" for various governments or free agents who aren't willing to get their hands dirty, including corporate leaders, the Tycho Group, Galilean scientists and various OFS governors.
2496 – The present.
