First Appearance


The Launch Controller is a new block introduced in Galacticraft 2 which allows the automated liftoff of Cargo Rockets.

It requires energy to operate and also has a built-in chunk loader.

UI Settings

The UI of the Launch Controller

By right-clicking the Launch Controller, the user interface will show up.

On the top you will have the Frequency field which allows you to set the Controller's Frequency. It acts like an ID so be sure to make the ID is unique!

Next is the destination frequency which sets the target Landing Pad with its own Launch Controller.

(The screenshot here shows the Launch Controller with ID: 1 and target ID: 2 so with any luck the second Launch Controller does have ID: 2...)

Next we have got two buttons.

The 'Remove pad' button should normally be red. If you set it to green, it will break the launch pad at liftoff, the same as how a launch pad breaks when there is no Launch Controller. But you will have no way to recover the 9 launch pad tiles because when your launch-controlled rocket lands there is no Parachest or lander.

The 'Launch when' button enables multiple scenarios for an automated liftoff:

  • Cargo is Unloaded
  • Cargo is Full
  • Fully Fueled
  • Instantly
  • 10 Seconds
  • 30 Seconds
  • 1 Minute
  • Redstone Signal

Note: the "Cargo is Full" setting will not launch until the rocket detects that it can accept no more items - detected by trying to put an extra item into the rocket and failing. Example: if the cargo rocket has 17 full stacks, and the Cargo Loader is now loading it with wood and it has a half stack of wood in slot 18, then it is not "full" because it can still take more wood. But if the Cargo Loader's next item is coal, there is no slot to put that into, and so the rocket will be detected as "full" and will now launch.


  • Only the chunk where the Launch Controller is will be kept loaded by Galacticraft, not the neighboring chunks.
  • To avoid cutting off energy/fuel supply and item unload/load when you leave the area, put all apparatus needed for your system - including the cargo unloaders and any chests etc - in the loaded chunk, with any needed electrical systems as well (build upwards or downwards if you need more space - you can fit a huge base into one chunk if you try), or use extra chunk loaders from a different mod.
