# Fuel Tanks

### **Receiving the Fuel Tanks Schematic:**

* Configure Satellite Mission from the Ground Control Station
* Small chance from Aerospace Research
* Participating in the Grab a Hopper Tournament.
* Participating in Marisol's Tournament
* Purchasing From Duskworks Landing

### What does the Fuel Tank do?

The Fuel Tank's main function is the distribution of Rocket Fuel. Due to the volatility of Rocket Fuel, it is unable to be traded on the Marketplace. Duskworks advises settlers to instead set up Fuel Tanks filled with Methalox as rentable "gas stations" for settlers to pick up Rocket Fuel for their Hoppers.

Rocket Fuel can be created out of Pure or Impure Methalox, filling three cryogenic canisters at a time.

{% hint style="danger" %}
Rocket Fuel can not be sold on the in-game market. Additionally, there is no current use for Rocket Fuel but will be used soon for Hoppers.
{% endhint %}

### **Crafting the Fuel Tank:**

**Building: Engineering Bay**

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.milliononmars.com/playerguide/buildings-for-your-martian-homestead/aerospace/the-buildings-of-aerospace/fuel-tanks.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
