Space Exploration
Your mission begins in the Overworld, but your destination lies beyond the Sol system. To leave Earth, you must construct a space-capable rocket and fly off into the sky. Once your vessel reaches an altitude of 500 blocks, you will be transported to the next dimension in the following order: Luna, Venus, Adrian, and Erid.
