The State of Earth
At a cursory glance, this Earth looks rather similar to the one we know today – it remains fractured into numerous states, competing and collaborating with each other continually. The average person is still far more concerned about their next paycheck than the worlds beyond the stars, and that is not likely to change at any time in the near future.
And yet, there are differences – some subtle, some profound. While public space programs still exist – and many of the more established ones remain among the leaders of exploration and research – they have been joined by a variety of private corporations, a process mirrored on the surface, as non-governmental entities of numerous varieties have begun to take powerful roles in politics, identity, and daily life – especially in regions which trend towards international cooperation, like Europe, or in regions that remain developing or have recently begun to come into power of their own, like much of Africa and Asia.
More prominently, Earth is no longer the only home of humanity, and the nature of the colonies – which range from small self-sustaining research satellites to massive Martian sprawl – has become quite varied; some remain under the control of their home nations, while others run de facto – or even, more rarely, actual – independence. These complicated relations are not made easier by the presence of large permanent populations in private colonies, which often exist in territory not party to any government, encouraging a unique and politically difficult identity for the people who live there.
The next topic is
the state of technology on Earth. Please paint this in broad strokes - I will, as a general rule, reject proposals which attempt to delineate plasma engines or what not. What I'm looking for instead is a bit more of what fields have seen progress or interest - for example, do we still rely on traditional computers, or have we had research and breakthroughs into other sorts of information systems? Does biotech still have a nasty PR problem, or has it become more embraced - and regardless of its perception, is it used? Stuff like that. Please keep in mind that this question is for Earth as a whole (or the colonies, or developing vs developed nations) rather than specific entities or the expedition.
