Interplanetary Engineering

The discipline of designing and building the infrastructure for a multi-planet species. This is civil engineering, but on other worlds with different gravity, no atmosphere, and deadly radiation. It involves constructing pressurized habitats, landing pads, power grids (likely nuclear or solar), and transportation networks (like pressurized rover tubes or orbital elevators). It requires solving novel problems like managing static-cling dust that destroys seals and building with materials you mined on-site yesterday.

Example: "Interplanetary engineering on Ceres is all about spin gravity. They're designing the Canyon Cities—habitats built into massive trenches, with the whole asteroid spun up to create 0.3g on the inner trench walls. The chief engineer's biggest headache is calibrating the sewage flow for a coriolis effect."

Interplanetary Sciences

The focused study of other planets and celestial bodies as places to understand and eventually inhabit. It goes beyond pure astronomy to include planetary geology (are there stable lava tubes for habitats?), comparative climatology, extraterrestrial soil chemistry (for agriculture), and the search for native life that could complicate settlement. It's applied planetary science with a direct goal: to assess resources, evaluate risks, and provide the knowledge needed to build a home off-Earth.

Example: "Her team in interplanetary sciences isn't just looking for water on Mars; they're modeling the perchlorate distribution in the soil to find the best sites for a bioremediation plant that can detoxify the dirt for future farms. It's environmental science for a world that doesn't have an environment yet."
