Ad-Astra: Giselle Addon
Giselle Addon adds space suits, diving gear and compatibility armor to the Ad Astra space mod, with oxygen and energy handled by the armor pieces themselves.
What it does
The addon adds a basic space suit and a netherite space suit, each filled with oxygen, plus a jet suit that carries both oxygen and energy. A diving helmet, boots and backtank, and a netherite version of the same set, let players breathe underwater. Oxygen can be filled into all armor and inventory items, and netherite oxygen can be used on hot planets in place of the regular kind.
The addon requires Ad Astra, Botarium, Resourceful Config and Resourceful Lib. Its armor sets for Mekanism and PneumaticCraft are only active when those mods are installed. Other optional integrations include Create, Just Enough Items (JEI), Mekanism, PneumaticCraft: Repressurized and Tinkers' Construct. A server running it needs every connecting player to have it too. Files are published for Fabric, Forge and NeoForge across seven release versions, 1.19.2 – 1.21.1, and the code is open source under the MIT License.

Use cases
Hot planet travel
Netherite oxygen lasts longer on hot planets, so a player can swap it in for the regular oxygen supply.
Underwater exploration
The diving set lets a player breathe underwater, and the Mekanism armor can fill its gas from water or rain.
Who it’s for: Players of Ad Astra who want armor for space travel and underwater work, and server owners who run Ad Astra with Mekanism or PneumaticCraft.
