The NASA Workbench, also known as Rocket Crafting Table, is a specialized item assembly table which is used to craft a Tier 1 Rocket as well as other unlockable vehicles and items which require schematics in order to unlock them.
This is important because there is no other way of making a spaceship! Once the player has made the 1st spaceship they can then get to the Moon.
Galacticraft 2 and Galacticraft 3:
The NASA Workbench is 4 blocks tall and 3 blocks wide, so be sure to allow ample space when placing.
Right-clicking on the Workbench will pull up the interface. By default this will show the 'Tier 1 Rocket' as it is already unlocked. You can change tabs by pressing the Next or Back buttons on either side of the inventory.
Schematics can be added via the Schematics tab, enabling you to create a broader range of space vehicles. Currently, the only other vehicle schematics available are the Moon Buggy, the Tier 2 Rocket, the Tier 3 Rocket, and the Cargo Rocket.
Adding storage space
Each green box adds 18 slots of storage in the vehicle inventory: 18, 36 and 54. It must be done along with the crafting of the vehicle. It is not possible to add storage in an existing vehicle.
