Extractors can be placed on a any planet that you have fully completed. These extractors then last for a certain amount of time before they are available for collection. Once you collect them you are given a bundle of one of the fours resources that the planet in question drops.

In order to get an extractor you must purchase the blueprint from the foundry. Extractors can be reused however as you use them they may lose health, this regenerates over time when they aren't in use.

The number of extractors that you can have deployed at once depends upon your mastery rank.
