Seablock but without the sea, and you make a rocket by duplicating resources instead of from water. Build your own space station / satellite / orbital rocket launchpad / factory thing
Just recently discovered Spaceblock is incompatible with the Furnace Recipe Selection mod. not sure if you can update spaceblock to be compatible or not as the recipe mod for furnaces really helps with things like rate calculator and stuff as it allows you to force select a recipe for your furnaces (and you don't accidently smelt stone in an iron line and end up with a mess)
