(You) got to have faith!

So we are studying how hard it is to, first of all escape from our planets gravitational pull, and secondly once escaping that field, to be able to take off from a rotation planet and then land on another rotating planet. I mean, you miss by a mile and you can't catch up with a planet with a spaceship. Spaceships do not go that fast. So you are pretty much sunk. So imagine all the work it takes just to figure out how to shoot the rocket and with what speed and angle. Crazy isn't it? MAN! Physics is mindblowing. Insane stuff, insane!!
