The Space Program

The Space Program is an advancement journey through rocketry, survival equipment, orbital operations, and a Moon landing and return.

Craft or launch a Firework Rocket to reveal the tab. Progress begins after Cosmonautics is installed; earlier accomplishments are not inferred.

Early rocketry

The opening milestones lead from lighting a Firework Rocket to building a launch pad and establishing Mission Control. Rocket Fuel and Oxidizer form parallel preparation branches before experimental V-2 and Sputnik development.

Fuel and Oxidizer milestones each track 30 crafted items. These advancements describe and reward the journey; they do not lock the underlying recipes or commands.

Orbital branch

The optional Station branch includes:

  • Low Earth Orbit: arrive at a Station by a normal rocket mission.
  • Station Online: bring a Station machine online with adequate solar power.
  • Harvest the Heavens: be present when a powered asteroid collector delivers resources.
  • Orbital Defense: destroy an asteroid with the Station's Copper Cannon or Missile Turret.

Reaching low Earth orbit awards an EVA Harness.

Moon branch

The lunar branch begins with Cleared for Launch, earned by boarding a complete, valid Artemis site, and One Small Step, earned by completing the Moon landing. It then branches to The Long Way Home, for completing the lander's return to Earth, and Home Away from Home, for successfully deploying a habitat in an oxygen-controlled world.

One Small Step awards a Habitat Deployer. The Long Way Home awards eight Firework Rockets. Other milestones award experience and occasional one-time items.

Continue beyond the advancement goals by exploring catacombs, refining Lunar Alloy, building a breathable base, and crafting Lunar Rovers. These activities do not require a separate advancement unlock.

Guidance, not gates

Advancements show useful goals and celebrate accomplishments, but they never gate commands, recipes, travel, or other plugin features. Use /cosmo guide for the concise in-game route and /cosmo route <destination> when you are unsure what a launch still requires.
