Extrapolation

Extrapolation is a building game about the logistics of filling the solar system with life. Mine and process resources from the Moon, Mars, asteroids, and beyond to support an increasingly self sufficient space civilization.

Extrapolation was designed to answer questions like:
"What kind of infrastructure would be necessary to build a rotating space habitat with thousands of inhabitants?"

"Is it more practical to mine resources from the asteroid belt or from Mars?"

"Does it make more sense to spread a space civilization out across the solar system, or to concentrate it into a few locations? What kind of resources would be sent across the solar system?"

"What kind of relationship would a space civilization have with Earth? How dependent would it be on Earth, and how could it benefit Earth?"

Extrapolation is set in a 1:1 scale model of the Solar System, including real planet topography data from NASA and thousands of real asteroids. In contrast to many space games which focus on the technical details of rockets and life support, Extrapolation tries to focus on strategic issues without glossing over the fundamental differences between travel in space and on Earth.

Launch resources using realistic orbital dynamics, taking into account fuel consumption and delta-V.

Build orbiting and surface based space habitats and factories. Choose between polar and equatorial orbits (or something in between), taking into consideration the launch cost from different surface locations to these orbital locations.

Send resources back to Earth to combat climate change

Build realistically sized Space Elevators, O'Neill Cylinders, electromagnetic mass drivers, and more, and see how useful they are for your goals.

Use orbital mirrors to illuminate solar panels on the night side. Beam power from orbital power stations.
