Ad Astra: GalileoX
GalileoX, an addon for the Ad Astra mod on Fabric, reworks radiation, weather and several existing mechanics and fixes bugs in the main mod.
What it does
Ad Astra and Botarium are both required. GalileoX extends Ad Astra by improving mechanics that already exist in it, enhancing world generation, and adding new mechanics written by the addon author. Some of the content it brings back comes from unused items, textures and code fragments found in the Ad Astra files.
A radiation mechanic based on solar wind is added, along with a Biodosimeter that tracks how much radiation a player has accumulated and how much anti-radiation medication is in effect. Weather systems in the Ad Astra dimensions are reworked. The addon also attempts to fix bugs and unfinished features in Ad Astra, and it can change some of the main mod's settings for modpacks and servers.
Because it runs on client and server, both the server and every player need the mod. The latest Fabric file is 0.4.1 for 1.20.1, published 2026-05-27 under the MIT License, which is not open source.
Key features
Solar wind radiation
Radiation exposure builds up from solar wind, changing how players must prepare for time on certain worlds.
Biodosimeter
The Biodosimeter reads a player's accumulated radiation exposure and the level of anti-radiation medication currently active.
Reworked weather
Weather systems in the Ad Astra dimensions are changed, so conditions on those worlds differ from the main mod.
Configurable settings
Options can be changed in the config file, and a missing or damaged config is regenerated when the file is deleted.
