About this Mod
This mod adds a space travel system, space stations, satellites (NYI), dyson spheres and planets to GregTechCEu Modern to aid a better and longer GregTech experience with more extreme systems for endgame.
The Dyson sphere can generate massive amounts of energy per tick, but beware! It'll disable the sun and cast eternal night on the solar system you built it on. It also needs maintenance or it'll fall into the sun.
The rockets are built like in advanced rocketry, from block parts, instead of a prebuilt shape.
Satellites do interesting things ranging from tracking entities to a DEADLY LAZER
Interplanetary travel can be achieved easily enough, although harder-to-get-to planets will require better fuel tanks and the like.
