Gases
<ad_leaderboard_A /> Galacticraft involves dealing with several different gases. Careful handling of gases is important in Outer Space!
Contents
Galacticraft 2
The only gas implemented in Galacticraft 2 is Oxygen which can be collected, piped, and used in several different machines. It an essential part of the life support systems for a player in a Space environment.
- Oxygen (breathable)
Galacticraft 3
Galacticraft 3 adds several gases, some of which can also be converted into liquid form.
List of gases in Galacticraft 3:
List of liquefied gases in Galacticraft 3:
Methane can also be liquefied, in which case it is known as Fuel
Trivia
- In Galacticraft 3, all the gases and liquefied gases are coded as Forge fluids with their scientifically correct density, viscosity and temperature (taken from NASA data). This data is not currently used in Galacticraft 3, but if there is another Forge mod which makes use of this detailed fluid data then it will be accurate
- In real life, methane, ethane, and propane, or a blend of them, are often liquefied for ease of transportation and to make a fuel: Liquefied Natural Gas (or LNG).
Breathable Oxygen
"Oxygen" in Galacticraft can mean either breathable Oxygen, or pure (industrially-made) oxygen.
A range of machines in Galacticraft handle breathable Oxygen so that players can breathe in a space environment. An Oxygen Collector collects oxygen, Oxygen Pipes pipe it to other machines, an Oxygen Storage Module can be used to store it.
The oxygen can be used in:
- Oxygen Compressor - used for filling player air tanks
- Oxygen Distributor - used for making a bubble of breathable air in an unsealed space
- Oxygen Sealer - used to fill a Sealed Space with breathable air.
This breathable Oxygen is not considered pure and so it cannot be used as oxygen for industrial purposes. It can be thought of as impure because it has other gases, for example, nitrogen, mixed in with it, to make a suitable mixture for players to breath in space.
All the air blocks inside a Sealed Space are filled with breathable air. See also: Breathable Air.
Oxygen
Galacticraft 3 introduces a purer form of oxygen made by industrial processes. It can be made either by electrolysing water in the Water Electrolyzer, or simply by feeding air on the Overworld into a liquefaction plant, the Gas Liquefier.
Uses:
- making Liquid Oxygen
- it can be piped through Oxygen Pipes into the Oxygen Storage Module, Oxygen Compressor, Oxygen Distributor or Oxygen Sealer and used in exactly the same way as the breathable kind of oxygen
- it can be used by any other industrial mod which has a use for a Forge fluid named oxygen
So, Oxygen produced industrially can also be used as breathable oxygen. But breathable oxygen cannot be used industrially.
Liquid Oxygen
Liquid Oxygen is a cryogenic (extremely cold) liquid form of Oxygen. It is a useful way of transporting Oxygen in a compact form. It can only be transported in special canisters.
If Liquid Oxygen is used in a normal oxygen-using machine, the liquefied oxygen turns back into a gas. 1 bucket (1000 mB) of Liquid Oxygen can make 5,555 units of breathable oxygen.
Using the Liquid Oxygen Canister, Liquid Oxygen can also be used to refill player oxygen tanks in an emergency.
Trivia
- In real life, Liquid Oxygen is transported in special flasks used for handling super-cold liquids.
- At -183 °C it will be a constantly boiling liquid, whenever exposed to normal room temperatures. It boils rapidly because, to the Liquid Oxygen, room temperature (25 °C) is a very hot temperature, well above its boiling point. When it boils it becomes oxygen gas.
- Because it is pure oxygen, Liquid Oxygen is extremely dangerous used near to any sparks or naked flames: any flammable object will burn almost instantly in pure oxygen (especially if it is dunked in liquid oxygen!)
- In the aeronautics and space industries, Liquid Oxygen is often known as LOX

Nitrogen
Nitrogen is the main component of the Overworld atmosphere, and also found on Mars. It has no special uses in Galacticraft, except that it can be liquefied into Liquid Nitrogen. It can be considered a by-product of the process of making Liquid Oxygen.
Liquid Nitrogen
Liquid Nitrogen is a cryogenic (extremely cold) liquid form of Nitrogen. It is a way of transporting Nitrogen in a compact form. It can only be transported in special canisters.
If a Liquid Nitrogen Canister is used (by right-clicking) on certain blocks, some of it will spill out and can cause the blocks to freeze.
Hydrogen
Hydrogen gas is one of two products made when water is electrolysed using the Water Electrolyzer.
It is used in the Methane Synthesizer.
It can be piped using Forge fluid pipes in other mods, using Pressurized Tubes from Mekanism mod, or using the Hydrogen Pipe in Galacticraft (coming soon).
Methane
Methane is made from carbon and hydrogen. With further processing, it can form a useful Fuel.
Trivia
The very cold outer planets of the Solar System - for example Titan, a moon of Saturn - are known to have lakes of liquid Methane. Liquid Methane is not yet implemented in Galacticraft.
Carbon Dioxide
Carbon Dioxide is the most abundant gas in the atmosphere of Mars.
It can be used as a source of carbon in the Methane Synthesizer if fitted with an Atmospheric Valve.
Trivia
- Unlike other gases, Carbon Dioxide cannot be liquefied. If cooled, it forms a solid which looks like ice or snow, known as dry ice.
- In real life, the cold polar regions of Mars are sometimes covered with Carbon Dioxide snow, causing them to look white like the polar regions of Earth. Mars can also have clouds formed of dry ice.

Argon
Argon is a neutral gas, and one of the components of the atmosphere of Mars. It has no current uses in Galacticraft. It is best to discharge it into the atmosphere using an Atmospheric Valve.
