Wow! Thanks to asking in the KSP forums on how to make a good ship, I got a lot of responses and learnt how to make a ship that could escape Kerbins orbit! But as I did this, I managed to miss landing on the Mun AND Minimus (yep I missed a target the size of the moon.....literally!), so that leads me to this question, how do you properly predict where to fly and how? I tried using the apoapsis thing, but as you could expect, I am no genius with it either, help! All answers appreciated! Thanks!

Thanks, to everyone who responded!

I have being playing KSP in career mode for a while, and although I can successfully get a rocket into orbit I still cant get it into the Mun's orbit or even out of Kerbins orbit, is there any advice I could get to help me reach the stars? All advice is greatly appreciated Thanks
