Space Age Planet Order

The commonly recommended first-playthrough planet order, why Vulcanus goes first, and why Aquilo is saved for last.

At a glance

Recommended orderVulcanus, then Fulgora, then Gleba, then Aquilo.
Why Vulcanus firstIts Foundry casts metal from free lava, which dramatically cheapens iron and copper back on Nauvis.
Why Aquilo lastIt needs the most prior infrastructure and gates the endgame.

You reach the planets only after launching your first rocket and building a space platform. Each planet has unique resources, a signature building, and one science pack.

OrderPlanetWhy goSignature building
1VulcanusFoundry cheapens all iron and copperFoundry, Big mining drill
2FulgoraScrap recycling and holmiumElectromagnetic plant, Recycler
3GlebaBiological tech and agricultural scienceBiochamber
4AquiloCryogenic tech, gates the endgameCryogenic plant

Do this in order

  1. Launch a rocket from Nauvis and build a space platform with thrusters.
  2. Fly to Vulcanus first. Stand up Foundry production and ship the savings back to Nauvis.
  3. Go to Fulgora for the Electromagnetic plant and scrap-based components.
  4. Take on Gleba next. Its spoilage mechanic overturns the build-and-forget habit, so expect a rethink.
  5. Save Aquilo for last, once you have cryogenic plants, heating, and fusion power ready.
  6. From Aquilo, push toward the solar system edge for the Space Age victory.
