Project Hail Mary - Dimensions Mod

Players build a space-capable rocket, fly it off the sky, and reach the next dimension once the vessel passes 500 blocks of altitude. Travel between planets requires fuel, and the rocket is the only transport between the worlds. The mod is inspired by the film Project Hail Mary and is a first release for Minecraft 26.1.2.

Beyond travel, the mod adds tiered equipment built from heavy-duty corrosion-resistant metals, heat-resistant materials for hostile worlds such as Venus, and extraterrestrial mobs including large alien bosses. Players start with a base spacesuit crafted from iron ingots and white wool. Servers that run it need every player to install it too. It requires Fabric API and is released under All rights reserved, so it is not open source.
