Tier 4 Rocket (More Planets)
For this type of rocket you need to upgrade your NASA Workbench with a Tier 4 Rocket Schematic. This schematic can be acquired in a Moon Dungeon. To build the rocket you will also need Tier 4 Heavy Duty Plate, Tier 4 Nose Cone, Tier 4 Booster, Heavy Rocket Fins, and Tier 4 Rocket Engine
The Rocket is crafted using the NASA Workbench, to craft it you must fill up all the respective slots on the workbench. The Rocket requires one Tier 4 Nose Cone, ten Tier 4 Heavy Duty Plate, two Tier 4 Booster, four Heavy Rocket Fin, and one Tier 4 Rocket Engine. You can get a pre-fueled version of every spaceship in creative mode.
You can use it the same way as the other rockets. Once you have left the atmosphere you will get to the Planet Selection Screen, which allows you to select Mars or the other dimensions.
Note: breaking the vehicle causes it to lose all its fuel.
