Galacticube
Galacticube adds a Moon dimension to Fabric games for 1.20.1, with low gravity, vacuum survival and rockets.
What it does
Galacticube is a Technology mod that adds a new dimension modeled on the Moon. Players reach it through a rocket built from blocks, then stand on the surface, where the air is absent and the gravity is low. A helmet is needed to breathe, and a glass helmet is included as a placeholder for that purpose. Lunar stone and lunar dust can be mined on the surface.
The author describes the mod as an early alpha prototype, not a finished product. Its files are alpha builds for the 1.20.1 range only, and the author warns that bugs, changes and missing features should be expected. The latest Fabric file is 2.0.0 for 1.20.1, released 2026-01-05 on the alpha channel.
Only the client needs the mod, so servers run without it and players install it on their own game. Galacticube is not open source. It is distributed under the Creative Commons Attribution Non Commercial No Derivatives 4.0 license, which governs how the files may be shared and changed.
Key features
Moon dimension
A new dimension with a Moon-like surface, reached by a rocket built from blocks.

Jumps reach higher and falls descend more slowly on the lunar surface, and bounce movement is available.
Vacuum survival
The surface has no air, so a helmet is required, and the glass helmet is a placeholder for a future design.
Lunar resources
Lunar stone and lunar dust can be mined from the Moon surface blocks.

Use cases
Early testing
Testers can try the rocket, dimension travel and vacuum mechanics on 1.20.1 while the mod is still in alpha.
Who it’s for: Players who want to experiment with an early space exploration prototype on Fabric for 1.20.1. The author expects bugs and incomplete features, so it suits testers more than players who want a stable survival addition.
