Deep Space
by confect1on
Deep Space lets players travel between dimensions by flying above a set height, and it is built for NeoForge with Create and Veil installed.
What it does
Going above a certain Y-level places the player in space, from which they can travel to other planets. The mod allows cross-dimensional travel through a space dimension that players interact with, and server administrators can define which planets act as dimensions. Because the space view is rendered in 3D rather than as a GUI, players can build actual space stations that orbit planets and move between them across dimensions.
Two required dependencies must be installed next to it: Create and Veil. Every player and the server need a copy of the mod. Deep Space is open source under the MIT License, and its source code is public. Files are published for NeoForge across nine release versions, 1.21 – 1.21.8, with 1.4.5-RELEASE for 1.21.1 as the latest file, dated 2026-07-19.
Key features
Cross-dimensional travel
Players travel between the space dimension and planets, moving from one world to another without a loading screen.
Server-defined planets
Server administrators choose which planets act as dimensions, so a server can set its own travel map.
Orbiting space stations
Players can build space stations that orbit planets and move between them while staying intact.
Survival equipment
Angel blocks, a jet suit, a jet helmet and oxygen items are included for life in space.

Use cases
Geopolitical roleplay
The travel system supports roleplay servers where factions claim planets and conflict over space routes.
Who it’s for: Server owners who want a planet-hopping progression on NeoForge, and players who enjoy building stations and exploring other worlds.
How it compares
Advanced Rocketry 3 is also a NeoForge mod for 1.21 – 1.21.1, with client and server environment, but it is released under All rights reserved and is not open source. Space Explore covers 1.21.1 under the MIT License, where Deep Space is open source across nine versions. Create: AeroStar Northstar Comp is open source under the MIT License for 1.21.1 only.
