Hey everyone! I currently have researched everything in the heavy rocketry column. I've gone to mun, and minimums several times. I'm wondering what I should try and do next? I can't build a space station yet or any rovers so I don't know if I'm ready to go to other planets yet? Should I keep going to bodies in Kerbal orbit until I get things I can use for missions to other worlds? I also have 559 in science right now and don't know what to use it on. https://drive.google.com/
