Hello,I don't have any problem launching from the moons surface,and getting back to my earth base using IMFD,but I can't figure out how to do it while in orbit around the moon,I always either end up far away from the earth,or crashing into the ground on earth,is there a good procedure?I just can not seem to figure out these steps using IMFD.Something I could print out would be great if possible.
I recommend using LTMFD for this. You can set a target perigee, and then you just perform an EOI when you get there.
It sounds like that its just your first TEI burn is just not accurate enough.
Which is fine. It is actually expected from IMFD, because of the other gravity sources, mainly the Sun, and the fact you jump from one sphere of influence to another, if you use IMFD you are gonna need to do a couple course corrections. When coming back from the moon you may have to do at least 2.
Open orbit mfd, and set reference to Earth. When the number on the center bottom turns green (which it will when it hits 0.50G, perform a mid course correction to set your perigee to what your target. LEO, say that is 220km.
You may need to do another one several hours later if it drifts too much. To see what your projected perigee with more accuracy, use IMFD's map program, set to MAX accuracy. It does a great job taking into all the gravity sources to figure out where you will end up. Orbit MFD is not nearly as reliable, you should only use it for that one number, the G number, which tells you when it becomes the dominate gravity source.
If you use LTMFDs TEI program and set it to orbit insert and not leave it in Reentry mode, you may only need to do one course correct. Or maybe not, if your projected Pergiee say, floats up from 220km to 350, or even up to 500km...that may not be a problem, you are still in LEO up there.
