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.

The Oxygen Tank is an oxygen storage item, and a smaller version of the Backpack's internal Oxygen storage. It can be attached to any slot on the backpack, including its widget slots.

  • When connected via a Tether to a base module or vehicle, the Oxygen Tank will fill with Oxygen.
  • The Oxygen Tank attaches to any Tier-1 slot and stores exactly as much Oxygen as the backpack's main tank (72 seconds when idling, 50 seconds when running.)
  • Having one Oxygen Tank in the backpack doubles the player's Oxygen storage.
  • When untethered, the Oxygen Tank's Oxygen is consumed prior to the backpack's. The oxygen gauge on the tank visibly empties as it is used.
  • If the player attaches a full oxygen tank to every auxiliary and widget slot on their backpack and Terrain Tool and idles, they will be able to breathe untethered for about 16 minutes.
  • If running while carrying the same load of Oxygen Tanks, they will be able to breathe untethered for about 12 minutes.
