The Space Program
The Space Program is a 29-milestone advancement journey through rocketry, survival equipment, orbital operations, cooperation, lunar exploration, and settlement.
Craft or launch a Firework Rocket to reveal the tab. Progress begins after Cosmonautics is installed; earlier accomplishments are not inferred.
The Space Program branches from early rocketry into survival, Station, and lunar progression.
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:
- Reaching low Earth orbit
- Learning RCS course correction and EVA tethering
- Assembling station equipment
- Harvesting real asteroid output
- Visiting another player's dock
- Completing a Station voyage and returning safely
Reaching low Earth orbit awards an EVA Harness.
Moon branch
The supported lunar branch begins with a cleared Artemis launch and One Small Step. It continues through returning home, repeated lunar travel, breathable habitats, settlement, lunar crafting, and entering generated catacombs.
One Small Step awards a Habitat Deployer. Other milestones award experience and occasional one-time items.
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.
