Which build do you need?

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Cosmic Rocketry

A Mod Made to extend Ad Astra's Tiers of rockets. They do not by default contain any recipes and this mod is mainly meant for modpack developers.

The mod was designed specifically for the modpack "Cosmic Frontiers" https://www.curseforge.com/minecraft/modpacks/cosmic-frontiers

A Huge thanks to the devs of Ad Astra for allowing usage of their models/textures for bases/inspiration for higher tier rockets!
