The following is a comprehensive list of the major exoduses from Earth, as well as major worlds colonised and missions undertaken within their respective time periods.
It is important to note the "Earth" is synonymous with the Sol System and the surrounding populated and developed systems in the latter two exoduses, as the appeal to migrate outwards was not limited to Earth in itself. They are referred as "Exoduses from Earth" as Earth was by far the most important world in the area at the time, and most Outer Sphere residents view Earth as synonymous with the Inner Sphere.
Solar Exodus - 2,483 CE to 2,530 CE
The Solar Exodus comprises of the time period where the majority of the Sol System was settled and colonised, from Mars to Saturn. Though the first manned missions to the inner planets had happened centuries earlier, the Solar Exodus marks the first time mass human transit and economic movement between planets happened in history. Many former colonies of Earth became independent, while the Martian Civil War tore the previously united colonies apart at the roots. Mining operations, followed by settlements, and then colonies were established in the Jovian and Saturnian systems respectively, with Titan and Callisto experienced a vast upswell in political influence and power over their respective spheres.
Many major events drove the Solar Exodus, including the development of economical inter-planetary transit, nanotechnology, and self-regulating microbiospheres, plus overcrowding on Earth and the Moon. Human civilization became tenfold more diverse and spread out, as new cultures developed and technology flourished.
| Ship(s) | Target | Benefactor Polity | Year Launched | Status |
|---|---|---|---|---|
|
Jupiter (Callisto) | Federation of Europe | 2 484 CE | Failed, eventually merged with the Sol Nascente settlers after their hab experienced a biosphere collapse |
|
Jupiter (Ganymede) | Federation of Europe/Commonwealth of China | 2 485 CE | Success, established a true presence in the Jovian System, strengthened ties between China and Europe |
|
Mercury | Federation of Europe | 2 487 CE | Success, established a minor colony on Mercury, later grew into Hermes-Icarus Colony |
|
Venus | Commonwealth of China | 2 487 CE | Success, established a major colony in Venus' atmosphere, and in low Venusian orbit |
|
Jupiter (Callisto) | Republic of Brazil | 2 489 CE | Success, recieved European settlers from the collapse of the Daedulus mission, established a major colony on Callisto, grew to become the capital of the moon and of the Jovian System as a whole |
|
Saturn (Titan) | Republic of India | 2 509 CE | Success, first mission to Saturn, established a major colony on Titan, grew to become the capital of the moon |
Of course, it is important to recognise that these are only a small selection of the many hundreds of major missions, and tens of thousands of minor ones, that spread humanity out to the dozens of worlds of the Solar System. The Solar Exodus also only comprises a fraction of all Solar colonisation and exploration - indeed, hominization of the Ice Giants and the Kuiper Belt stretched out many centuries, and even while the first interstellar missions were being undertaken the first people were standing on Pluto.
