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 EXO Biofuel Obtainment Operation is the fourth community Limited Time Event in Astroneer. It was added with the BOO Update, and was accessible through the EXO Request Platform. It ran from October 19, 2020 to November 30, 2020.


The main objective of the event was to collect Spookysquash samples, Volatile Attactus and Elegant Spewflower Seeds, and combine them in a Cauldrangea to produce biofuels. The biofuels were sent up with an EXO Request Platform to obtain various rewards.

  • You were required to send the resources through the EXO Request Platform with the Medium Gas Canister, which can hold 160 items of one resource at a time. You could also send 8 individual resources on the side of the EXO Request Platform, resulting in a maximum capacity of 168 items per launch. Each launch of the rocket costs 500 Bytes, no matter if the rocket has a full load or not.
  • Players could only send the currently requested resource in the rocket, and would not be able to send any other resources of other tiers of the event.
