Interstellar: Galaxy
by EvBe19
Interstellar: Galaxy is a NeoForge technology mod that adds travel between planets and moons, with galaxy-scale mechanics for players and servers.
What it does
The mod lets players travel across a galaxy of worlds. Rocket and transport mechanics move a player between bodies, and the trip is the central loop of the content. Recipes use dusts and ices from the moons, such as Galilean Dust mixed with Ice, Crushed Ice combined with Sulfur Dust, and Ganymede Dust, which ties the crafting chain to the places visited.
Both the server and every player need the mod, so it has to be installed on both sides. Files exist for 1.21.1, 1.21.4 and 1.21.8, with 1.5.3 for 1.21.8 as the latest NeoForge file, released 2025-12-24. The mod is released under the MIT License and is not open source. The author lists an issue tracker for bug reports.
The author warns that the mod is demanding on hardware. Some of its processes run several times per second, so a slower computer may struggle with it.
Key features
Travel across the galaxy
Players move between worlds in the galaxy, with travel as the main progression route.
Moon-based crafting
Dusts and ices gathered on the moons, such as Galilean Dust and Dirty Ice, feed the recipes.
Ice and sulfur processing
Crushed Ice combines with Sulfur Dust, and Galilean Dust mixes with Ice or Brown Dye for further products.
Frequent timed processes
Some machine and world routines tick four times per second, others twice per second or once per second, and a few run on a five-second cycle.
