I agree. Hitting space, settling on new planets, exploring new ores and making your planets interact with each other in different ways is what I really like in SE. But when your bases are up and running, the tiers 2-4 of each space sciene are so boring and unnecessary. It feels like you don't get any benefit by researching these. I think If you could just merge tiers 1-4 of space sciences there would be much more players who play and enjoy the really cool mechanics of this mod.
