The Space Age

I’ve suggested an order to use when building a fictional world and given you some ideas on how your culture could evolve from non-sentient to sentient beings. Now that your culture is developed on the planet, it’s time to see how you want it to develop in space. Most species will be able to send satellites into orbit before ships or stations are created. Even if a species was able to go to space immediately without dealing with satellites or stations first, they will likely have some sort of fleet of ships or satellites orbiting their planet as defense. You may want to decide what all is orbiting your planet and what defenses your planet has before focusing on an individual or class of ships or a nearby space station. Common planetary defenses are missiles and stations/satellites capable of stopping weapons or destroying ships.
