Thank you all for the greetings and advice! I look forward to poring over all that (and your helpful Exploring tutorial, Pecan) when I have the chance! I might look into some mods for the future, to simplify things, but I'd like to have a firm understanding of how it works first- rather than just strapping my Kerbals into a rocket without knowing what I'm doing entirely. =p Anyways, once again, thank you very much!
