Cosmonautics | Rockets, Moon & Spacestations

Cosmonautics is a minecraft space plugin done right. turn your survival server into a space program.

Players begin on Earth, learn the technology they need, build launch infrastructure, and gradually push into orbit and toward the Moon. Progress happens in the world: rockets are assembled and fueled, habitats must hold pressure, and a badly planned mission can leave a crew stranded.

It is all part of one connected journey rather than a collection of teleport commands. Multiple rockets, like Artemis, Soyuz, V-2, and Sputnik serve different missions, while oxygen, pressure, decompression, zero-gravity movement, and station construction make leaving Earth feel like a real step into the unknown.

A shared server project

Work together on a direct Earth-to-Moon expedition or build an orbital station along the way. Explore generated lunar terrain, establish sealed habitats, search catacombs, and follow the Space Program advancement path from the first experiments to a safe return home.

Private animated tutorials introduce the larger systems without changing real blocks, inventories, or gameplay state.

Current state

The current supported journey covers Earth, the Moon, and optional Station gameplay. The moon is a completely new dimension, the station is something new entirely, like a revamped skyblock
