Ad Astra: Planets+ Add-ons
Ad Astra: Planets+ Add-ons brings Mekanism and Thermal machinery into the Ad Astra planets, with extra planet content and compatibility blends.
What it does
Official add-ons for Planets+ extend Ad Astra with Thermal Space and Thermal Series content, plus Ad Astra Ores and Mekanism content for the same worlds. The add-ons are blended so that Thermal and Mekanism compatibility code does not clash between the two mods, which helps prevent bugs when both are installed together. A hub datapack by DeadbushCarrot, which Planets+ developed, is included.
The mod is built for Forge on Minecraft 1.20.1 and 1.20.4, with files for 1.20.1 and 1.20.4 in the 1.20.1 – 1.20.4 range. Ad Astra, Ad Astra: Planets+, Mekanism and Mekanism: Ad Astra Ores are all required. The server must run it, while a player may leave it out and still join. The code is released under the MIT License and is not open source.
Key features
Planets+ add-ons

Mekanism content
Mekanism machinery and Ad Astra Ores are added for use on the planets, linked to the Mekanism compatibility layer.
Thermal and Mekanism compatibility

Use cases
Who it’s for: Server owners who run Ad Astra with Planets+ and want Thermal and Mekanism machinery on the planets. Players join without installing it, since the server alone needs the mod.
How it compares
Ad Astra: Planet Screen Expanded is for 1.20.1 and is released under the MIT License, so it changes the planet screen rather than adding machinery. Astral Zinc is also for 1.20.1 under the MIT License. Ad Astra: Planetary Swapper is for 1.20.1 under the MIT License and is not open source, so it is a different kind of add-on.
