Hi guys, actually i'm a kind of "old" player (about 2 years and half of playing constantly KSP) but only recently i switched to career mode. Changing to this has opened to me the world of science in KSP, now i have a question, if you want to return 100% of the experiment is necessary to land on kerbin the mistery goo or materials bay? There isn't another way? How science recovery works? Thanks, Daze
