I wish they added rockets to EnderIO (powered by the Rocket Fuel). If there is Rocket fuel, why not Rockets?
Basic Rockets , you plop them down they look space-cool. Then you would place a special destination block where you want your rocket to go, which can be up to 1024 blocks away. Select that "destination block" on a GUI on the rocket and then shift right click to enter the rocket. Now once you are inside press the space bar and you will Blast at that block at 20 blocks per second (sprinting is 5 blocks per second, creative flight is 10).
The drill upgrade lets your rocket go through blocks. The speed upgrade increases the speed to 50 blocks per second.
The Advanced rocket is bigger. It is basically a controllable rocket. It travels at a speed you can set either to 15 or 30 blocks per second. There is no block to select, just hop in and control your rocket to its destination. Press shift to land.
If and only if you have galacticraft installed, the advanced rocket WILL be able to act as a tier 2 rocket to get to Mars.
The Ionic rocket is powered by Redstone Flux and travels at 15 blocks per second.
Nuclear rocket goes 40 blocks per second and runs on Yellorium.
By default, if you ascend 1,200 blocks and have 16 ender pearls in your inventory, you will go to the ender world.
