Genesis: Ad Astra
by G_Mungus
Genesis: Ad Astra connects the Genesis world generator to the Ad Astra space mod, so planets and space travel carry Genesis terrain and skies.
What it does
The mod integrates Genesis with Ad Astra and requires both to run. Once installed, Ad Astra planets are generated with Genesis terrain, and the Ad Astra skyboxes are replaced with Genesis skyboxes, which let a player see nearby planets and their atmospheres from orbit. Players can fly between planets and through the Genesis space content on a ship.
Oxygen and gravity from Ad Astra are also covered. The Oxygen Distributor works on ships, and the Gravity Normalizer works on ships as well, so a vessel can carry its own breathable air and gravity. Players need oxygen to breathe in space, and the integration keeps those systems in step with the Genesis planets.
The mod runs on the Forge loader for Minecraft 1.20.1 only, with the latest file 1.20.1-0.4.0 for 1.20.1, released 2026-04-15. It is open source under the MIT License and is published with source code. Its first file dates from 2026-03-27.
