Can't get a Mun encounter

[bobjohnson6]

I got KSP recently and I'm now ready to attempt a third Mun mission! (don't judge)

One problem: I can't get a Mun encounter. I've tried matching the inclination, which didn't work.

I've just been pulling the prograde handle until I get about as high as the Mun, but it doesn't seem to work. (Yes, I've tried moving the node) I've been able to get an encounter before, but now when I try, nothing happens. The encounter icons don't pop up anymore. Is this an update that I missed?

Mods installed:

=================================

Kerbal Engineer Redux

MechJeb 2 (When I use the MechJeb maneuver planner, I still can't get an encounter)

MechJeb 2 Embedded

EVE

 

I have Breaking Ground and Making History. Oh, and I have KSP through Steam.

 

EDIT 2-10-20: I have been able to get an encounter (with the Mun) before. Not sure if that helps, but thought I'd add it anyways.

No judgement here. Congrats on making it this far!

Not sure what the problem could be. If you could take a couple screen shots of map mode and post them somewhere (we tend to like imgur but anywhere we can see them is fine) maybe something will jump out.

Are you in career mode?   Prior to upgrading the Tracking Center, you don't get such niceties as encounter markers or all the other things we take for granted

Mun has an inclination of zero degrees, as you're having MJ, I suggest you use it to make your inclination around Kerbin zero degrees, and after that, you could try to create a Hohman transfer via MJ.

I don't know if this is the same as your problem, but sometimes after a long game session KSP will stop displaying my markers for closest approach and SOI changes. Restarting the game fixes things.

I attribute my problem to memory leaks or maybe a mod issue (I use a lot of mods). The problem only shows up after a very long play session. I leave the game running and put my PC to sleep, so one load of KSP might last me 20 hours of playing time. That's a lot of time for something to go wrong.

When the problem shows up I never see an intercept no matter how much I fiddle with a new maneuver node. Additionally, ships already maneuvered in flight such as a Duna encounter that is months away, will no longer show the upcoming encounter. That all comes back after restarting.

If you're on Tracking Station level 1, it doesn't show you patched conics on the map, so you'll only ever see your trajectory relative to whatever body you're actually orbiting at the time. TS level 2 shows you patched conics and I think it also allows you to target planets and moons, so setting up a transfer should be easier. Sandbox games have everything at level 3 but career will start at level 1, which may explain why you're having some trouble.

If you want to do it the old fashioned way, in stock KSP one 'month' is 4 Kerbin days and a typical transfer out to the Mun takes 1 day. By the application of "sums"^TM you'll need to time your transfer burn exactly 90 degrees in front of the Mun; or, to put it another way, if you're pointing prograde and the Mun is directly in front of you, BURN! Just try not to crash straight into it...

MechJeb has a maneuver planner feature that can automatically set up Hohmann transfers, although it will set up the transfer to travel straight to the Mun and crash into it- you'll need to tweak the burn slightly to avoid that. It will also execute the burn for you if you want. Useful, yes; cheating? Possibly, but that's what computers are made for! Alternatively, the Astrogator mod can also set up transfers to moons in the same planet's SOI and other planets orbiting the Sun
