Water Transport Infrastructure![](https://i.imgur.com/rFOAOK5.png)
Constructed on a water world, rocky-ice planet, frozen planet, or cryovolcanic planet, this structure transports water to another planet in the system. Does not require an artifact. Having it in place allows you to build:
Water Capture Infrastructure![](https://i.imgur.com/dmVAQcH.png)
Constructed on a desert world, this structure receives water and improves the planet to an arid, jungle, tundra, or terran world (depending on temperature). Does not require an artifact.
Cometary Capture Infrastructure![](https://i.imgur.com/dmVAQcH.png)
An alternative approach for desert worlds without a nearby water source, captures water-bearing asteroids to hydrate the planet. Does not require an artifact, but is slower and more expensive than standard water transport/capture infrastructure.

Removes pollution at a hefty credit cost. Does not require an artifact.
Integration Corps / Subjugation Corps

Two options for removing a decivilized population. The integration corps is costlier but greatly increases immigration while in effect; the subjugation corps is cheaper and faster but only slightly increases immigration. Neither requires an artifact.
Atmospheric Filter![](https://i.imgur.com/ne7iyZq.png)
Removes toxic or dense atmospheres. Requires an "atmospheric mineralizer" to complete.
Atmospheric Pump![](https://i.imgur.com/4RahryS.png)
Adds an atmosphere to a planet, removing the effects of null or thin atmosphere. Requires an "atmospheric sublimator" to complete.
Stellar Mirror![](https://i.imgur.com/cxCP3lJ.png)
Removes cold or extreme cold. The latter is costlier and takes longer. Requires a "stellar reflector core" to complete.
Stellar Shade![](https://i.imgur.com/KqwmjmP.png)
Removes heat or extreme heat. The latter is costlier and takes longer. Requires a "stellar reflector core" to complete.
Stellar Distributor![](https://i.imgur.com/cxCP3lJ.png)
Removes poor light. Requires a "stellar reflector core" to complete.
Tectonic Engine![](https://i.imgur.com/iL04OzD.png)
Removes tectonic activity or extreme tectonic activity. The latter is costlier and takes longer. Requires a "tectonic attenuator" to complete.
Cyclonic Regulator![](https://i.imgur.com/Lf7Q4Wp.png)
Removes extreme weather. Requires a "weather manipulation core" to complete.
Genepurge Project![](https://i.imgur.com/qFPucYV.png)
Unleashes engineered viruses to remove a planet's inimical biosphere. Does not require an artifact to complete.
N-Brane Oscillator![](https://i.imgur.com/qyqO4W6.png)
Adjusts the local gravitational field. Requires an "n-brane oscillator core" to have any effect.
Climate Sculpting Project![](https://i.imgur.com/0ZehbNB.png)
Can only be built on a terran or water world. Adds "mild climate," further reducing hazard rating. Requires a "terraformer brainprint" to complete.
Lobster Breeding ProgramAdds Volturnian lobster to a water world, but reduces relations with the Sindrian Diktat.
