How to calculate launch to make sat on polar orbit around the Mun

[Pawelk198604]

I need it to put it along Mun Polar orbit like here at the end of video,

The simplest, but probably not the most efficient solution: Go for the Mun as always, don't even bother with making it equatorial, make it as eccentric ad possible at AN/DN, change inclination to polar at the highest AN (make sure you do it in correct direction, otherwise you'd be going retrograde to desired orbit) and fine-tune it to demanded specs.

I made it but thanks

I don't know how to "Calculate" it but you can do it quite easily with maneuver nodes. Eject to Mun as normal, and then plop a maneuver node halfway there. Send it north or south a bit so you pass above or below Mun, and radial/prograde to pass directly under or over a pole. Bam. Done.

Advanced mode: You can acutally do this with the ejection burn.

yes, it can be smart to test out first that is cheapest, note that you have to aim for center of mun and not behind it as you usually do for orbits.

There is nothing to calculate.  Go to Mun any time and make the intercept a polar one.  Circularise into polar orbit; job done.  If you want a polar Mun orbit normal to Kerbin you're out of luck because it will change over the course of a Mun month.

Moving to Gameplay Questions.

Wait in LKO until Mun has moved ~45° forward.

Plan your transferburn, aim for Muns center.

As soon as you entered Muns SOI burn (anti)normal till your PE is at the designated orbit.

Circularise and do an inklination correction till the contract orbit is matched.

Done

Nope, he has to match an orbit from a contract  

[Goody1981]

For a slightly more accurate method (so that you actually arrive at the Mun at close to the correct inclination) you have to eject from Kerbin when your target orbit at the Mun is lined up along the Mun’s orbit path (can focus view on the Mun the check).

If it is, eject, and when you arrive at the Mun (1/4 of the Mun’s orbit later), the target orbit will now be lined up with your incoming path (perpendicular to the Mun’s orbit path). 

Finetune your arrival (well before you get there) so that you either pass above the North Pole, or below the South Pole, depending on the direction of the required orbit.

Oh. He never said that. "How do I do a polar orbit" and "how do I complete a satellite contract" are two different questions.

He did, was a bit hidden in the last 20s of his first video.

Anyway, my advice related to another orbit which could be seen, so my advice was also wrong.

Fortunately he managed it anyway
