![]() Depending on the orbital speed of the moon you're shooting for, it's distance from you, and how fast you plan on getting there, you will perform a prograde burn just after passing the opposite side of kerbin. The gimbal in KSP has indicators (green circle for prograde, green circle with an x through it for retrograde)Ĥ. Prograde to speed up/increase altitude of orbit, retrograde to slow down/decrease altitude of orbit. This is because with the exception of changing the inclination of your orbit, burning in any other direction is very inefficient and ineffective. That is to say, you want kerbin to be exactly between you and your target.ģ.NOTE: When doing orbital transfers you always want to burn facing either prograde (the direction your ship is already traveling), or retrograde (the exact opposite direction). After you've established a low, circular (even, as in your apoapsis and periapsis are roughly equal) orbit around Kerbin, wait until your craft is on the opposite side of the planet from the moon you want to get to. (what follows is a very rough description of a hohmann transfer - you can look it up for more details and a better explanation)Ģ. The rotation of the planet is the same as earth, and heading east gives you a speed boost that helps get you into orbit by burning less fuel. If you get the timing right, you can have a nice, neat circular low kerbin orbit without having to do any adjustments. You always want to launch straight upward, until at least around 20k ft, then s-l-o-w-l-y turn through the second half of your launch burn to heading 90 degrees (straight east). ![]() ![]() I carried over a lot of skills and intuition from "Orbiter" (a painfully realistic space flight sim), and might be able to help you a bit:ġ. ![]()
