Is there a rule of thumb for getting a rocket out of Kerbin's atmosphere? All that I've gathered thus far is that powerful rockets can get into space at shallower angles. Alternatively, a rocket solely designed for Kerbin orbit requires about a 45 degree angle when it's all said and done. Since target assist is not an option from launch, how do I know from rocket to rocket what the angle should be? Also, does career mode build off of the tutorials, or am I better off playing around in sandbox first?
