Gregicality Rocketry
Gregicality Rocketry adds a space travel system to GregTech CEu Modern, with rockets, space stations, satellites and Dyson spheres as late-game machines.
What it does
Rockets are assembled from multiblock parts, in the same way as advanced rocketry block parts, rather than placed as a prebuilt shape. Interplanetary travel is reached once a player has the required tech, and planets that are farther away need better fuel tanks than the nearby ones do. Satellites track entities and can fire a deadly laser, and the mod also covers space stations.
The Dyson sphere machine generates a large amount of energy per tick. It disables the sun over the solar system it is built on, which casts eternal night on that system, and it needs maintenance or the sun falls. The mod is meant for players who extend a GregTech world into an endgame of more extreme systems, and it works alongside Modern Space Addon Gregtech.
GregTech CEu Modern is required and must be installed alongside Gregicality Rocketry. The mod is open source under the GNU Lesser General Public License v3.0 or later. Files target 1.19.2 – 1.21.1, with 1.20.1 as the version that has Fabric, Forge and NeoForge files.
Key features
Multiblock rockets

Satellites
Satellites track entities across the solar system and include a laser that can destroy targets.
Dyson spheres
A Dyson sphere machine produces large amounts of energy per tick and dims the sun of its system.
