Thank you very much everyone! I already made it to the Mun, which had a great Impact on my Kerbonauts career (means: I descended a little bit too fast... Boom!). That may have been a small journey for my Kerbonauts, but a big step for my Mun Program. So I´ll try again... and again... and again. I also try to read not too much in the Forums, because most of the fun for me is finding out what works best and I don´t want to get spoiled. So I stick to the default Parts for now and my curiosity and creativity to see with what I come up next. Edit: I had to look up what the KRAKEN is :-) It seems like my Kerbonauts orbiting the Sun are too slow for that (20.000m/s). They will have a slow but steady sight seeing Tour and I´m curious how many KSP Updates they will survive :-)
