About this Mod

A mod for exploring beyond our own planet and into the outer reaches of space!

This is not meant to be a hyper-realistic mod! My goal was to keep the general style and gameplay of vanilla Minecraft the best I could, but with outer space. And some creative liberties, of course.

This is mod is still being updated! Sometimes updates might take a while though.
