I have to give a massive thumbs up to Artlav for this tutorial, it made my first few moon runs easy as pie! I havent as yet attempted to land on the Mun, but i have successfully managed several lovely circular orbits of Kerbal, then tranfer to the Mun. After a few more nice circluar orbits of the Mun (I am obsessed with perfectly circular orbits!) I then returned safely to Kerbal! Oh, and as an added bonus, i managed all that, and landed within spitting distance of the launch site!!!
