Autonomous cargo rockets: an exchange platform, but flying between the same modules carrying loads that the player will put on the rocket . A round-trip flight will cost 1 hydrazine, which is attached to the cargo rocket module. The choice of destination will look like this: each module in the saved world will have its own code (for example: 134,213,450) when you specify the location, you can enter the code of the module to be delivered. After collecting the incoming resource, you can put there a resource that will fly back and press the button, and the cargo rocket will fly back
