Orbital inclination help

[redivh]

I can't figure out how to change the orbital inclination to match Kerbin orbit so that I can get back from Duna.

I was wondering if there are any good guides or add-ons that could help me.

To change the angle of inclination of your orbit, it's player-easiest burn in the orbit-normal, or orbit-anti-normal directions.

If you're not using Mechjeb, orbit-normal and orbit antinormnal are unmarked points on the navball, on the horizon line between the blue and brown hemispheres, and exactly between your orbit prograde, and orbit-retrograde markers. If your orbit is or near-equatorial, you can get away with burning North or South on the navbal.

If you were to draw a line from your current orbit point through the center of the object you're orbiting TGhat's the line that your orbit will rotate around. Burn in the direction that you want the part of your orbit that's ahead of that line to pivot.

If you want to /match orbital planes/ with another target, you'll need to wait until you reach one of the two points on your orbit that go through the plane of the other object (often called orbital nodes). To find those points without Mechjeb, you'll need to go to the map screen, hit tab until the view is centered on the body both you and the other object are orbiting, and swing the view around until you find the angle where both your orbit and your target's orbit appear to reduce to straight lines. When you cross that intersection, that's where you'll need to do your inclination-change burn if you hope to put your eventual orbit into the same plane as your target

It's kind of like a gyroscope. When you apply a force to the edge of a spinning object, the reaction takes place 90 degrees in it's spin later.

You'll find that when you're just burning straight for the entire inclination, that your orbital altitude will begin to increase and the change in inclination will slow down. To counter this and save fuel, you need to constantly adjust to keep your burn at a right angle to your orbit.

Thanks! This really helps
