We often talk about the future of space as if it starts on Mars, in the asteroid belt, or among the stars. Giant habitats and interstellar travel dominate the conversation. Those ideas are exciting, but they skip over a much closer and more practical question.

What happens first.

In this episode of Entropy Rising, we focus on the place where humanity is most likely to learn how to actually live in space: Earth’s orbit. This is not an episode about distant megastructures or speculative technology. It is about infrastructure, economics, and incentives. The groundwork that turns space from a destination into a place where people stay.

Earth’s orbit already matters more than most people realize. GPS, weather satellites, and global communications underpin modern civilization, and all of it exists because we built orbital infrastructure when launch costs were far higher than they are today. Those costs are not fixed. Reusable rockets have already driven them down by an order of magnitude, changing what is economically possible.

We explore what an orbital economy really looks like. Not science fiction trade empires, but a gradual buildup of industries that benefit from being in orbit. Tourism, satellite assembly and servicing, and manufacturing processes that only work in microgravity all appear early. Tourism in particular provides revenue and political momentum long before permanent colonies exist.

We also discuss the constraints that shape early space industry. Launching material from Earth remains expensive, pushing resource extraction toward the Moon and near Earth asteroids. Human biology drives stations toward artificial gravity sooner than many expect.

If humanity ever becomes a spacefaring civilization, it does not begin on Mars. It begins above Earth. This episode is about the step we keep skipping.
