Player Guide

Your space program

Craft or launch a Firework Rocket to reveal the Space Program advancement tab. Its milestones guide development from Mission Control and propellant production through rockets, Station operations, and a Moon landing and return.

Advancements guide and reward supported actions; they do not lock recipes, commands, travel, or other features.

Journey to the Moon

  1. Craft a Launch Controller, Rocket Fuel, and Oxidizer.
  2. Run /cosmo tutorial launch-site to learn the private 10×10 Artemis construction lesson.
  3. Run /cosmo tutorial survive-space to learn suit equipment, pressure safety, and airlock operation.
  4. Build and board an Artemis launch site, or take the optional Station branch first.
  5. On the Moon, explore generated catacombs, create a breathable habitat, and find Lunar Scrap in secured colony loot rooms.
  6. Use the lectern inside the lander habitat with Rocket Fuel to launch the ascent stage home with your Scrap.
  7. Visit a Station and use its powered brewing stand to refine the Scrap into Solution, then craft Lunar Alloy for rovers and equipment. /cosmo tutorial moon-workshop demonstrates the process.

Safe tutorial boundary

Tutorials are private client-side lessons. They do not change real blocks, entities, inventories, player state, or gameplay state.

Station and EVA

The Station is optional for direct Earth–Moon travel, but required for the Lunar Alloy production chain. In zero gravity, use movement input for RCS corrections and hold Shift for a forward burst. An EVA harness can tether you to nearby solid surfaces.

At the Station you can assemble modules, process asteroids, produce gases, refine alloy, and visit another player's dock. Moving Station voyages and thrusters remain unreleased.

Run /cosmo tutorial space-station for a private guided demonstration, then read the Orbital Station guide for a concise reference.

When a launch is blocked

Use /cosmo route <destination> to see the missing requirement and next action. /cosmo status summarizes your current destination, suit, oxygen, canisters, and fuel. /cosmo planets shows environmental information and release availability.
