Astroneer Wiki

Hello all editors and users of the Astroneer Wiki! We are in the process of updating and switching over to use the new Fandom Desktop skin on the wiki. There will be many changes over the coming days, but the main goal is to keep the wiki feeling the same, as much as we can! If you notice any issues once the swap is made, please post them to the Admin Noticeboard so we can address it right away. We are also going to be completing the update to the Astroneer Wiki:Style guide, so there is a more up to date guide on how to style the wiki going forward.

Tier Small
Group Resource
Type Composite

Hydrazine is a composite resource in Astroneer. It is a purple liquid inside of a Canister, with a purple ring on top to indicate the amount of Hydrazine left. It is the only liquid in the game, and it is also the only composite resource that is not a solid.

Hydrazine is used to craft the following items:

Module Output Input
Chemistry Lab Graphene Hydrazine
  • Despite it appearing unlit in the Chemistry lab panel, a partially used canister can be used to make graphene.
  • Hydrazine can be used to fuel a spacecraft for travel using a Hydrazine Thruster. One canister is equal to 8 fuel units.
    • Takeoff costs 1 fuel unit.
    • Interplanetary travel costs 1 fuel unit.
    • Landing does not require fuel.
  • A canister of Hydrazine can fire a Hydrazine Thruster for 12.7 seconds when not on a spacecraft.
  • A canister of Hydrazine can fuel a single Hydrazine Jet Pack for 133 seconds in total.
  • A canister of Hydrazine can fuel a VTOL for 266 seconds in total. This is exactly twice the efficiency of a single Hydrazine Jet Pack.
  • Hydrazine explodes in a greater radius than Dynamite.
    • However, to detonate it you need either a nearby explosion or to put it in an active Smelting Furnace.


  • Hydrazine used to be stored in a Canister, and while it retains its old model it currently does not actually need a canister to be stored. A canister for it is generated when crafted in the Chemistry Lab, and will disappear when used to fuel a Hydrazine Thruster or craft Graphene in the Chemistry Lab.
  • Hydrazine is based on the real-life inorganic (i.e. not carbon-based) compound N2H4, which has historically been used as rocket fuel or as a component of rocket fuel[1].
  • When landing with a shuttle using a Hydrazine Thruster, explosive plants on Atrox may destroy your hydrazine (in backpack or attached to the thruster) and thus disabling further travelling.
