Quite doable and still one of the easier winning conditions.
I got an emperor space win today with the Babylonians, 1860, standard, continents, my best speed yet. More typically it happens mid twentieth century with a less science oriented civ.
I planted a lot of great scientists around Babylon, 8 or so. The city was pumping out around 800 bulbs by game's end and my civ was putting out over 1200 total. Lots of RA action, but I didn't burn any scientists on tech until the end when I could be sure that my science output was strong enough to get any tech in a single turn. I saved Oxford until the information age and managed to grab the Hubble telescope, which helped. Full freedom tree and lots of academies is the way to go now.
Need to try this out with Korea for giggles, they might do even better.
