Hello First I would say sorry for my English as it is not my narrative language. What I have done to get all my science points, and fill up my tech-tree, is to send out a probe with some science equipment and some solar cells and then just scan the different altitude of the moons and planets. The thing that I think is weird is that I am allow to set up an action group and spam click on the transmission button instead of returning any sample because I don't need to. This way I can harvest all the science points quickly. I personally got about 6000 science points for scanning Jool and its moons with a flyby to all of them, with only one probe. It got me thinking that, "Is this really fair?, did the developers know that I can do this". I filled up my tech tree with a days playtime and now I want to create a new career were I only transmit once or return the whole sample. Hope you know what I mean, is this really the way of doing science, maybe in KSP but still, I don't think that the scientist on the ground is interested in the exact same 100 samples of the same thing, even kerbal scientists if you know what I mean
