Hey thanks everybody, I finally made it! The keys were making sure I burn to approach Jupiter prograde, not retrograde. Then once I have a good hyperbolic approach, in Target Intercept tell IMFD to delay Tin until Europa is in a good spot on the other side and moving generally in the same...

Yeah, I just can't get the last burn right. I'm getting the flyby of Jupiter right, and ending up in the neighborhood of Europa at what looks like the right time, but orbit insert never works. Either it won't give me a burn vector at all or it burns me into some (apparently) random orbit...

Specifically, I'm trying to figure out how to sequence maneuvers to approach Jupiter in order to end up orbiting Europa, in a "realistic" way. I'm using IMFD 5.3b, but would be happy to hear any guidance for other tools too. This is with the UCGO arrow in the provided scenario for Europa. If...

FWIW, I just did a very clean orbit insert with IMFD 5.3b at the moon using the UCGO Arrow. The final eccentricity was 0.0001, PeA 48.48k, ApA 48.74k. This with 10x time compression turned on most of the time, or off. Maybe there are specific circumstances where there are a problem, but I...

I meant that Jarmonik could ask the author of the "Full Manual" - mark316 according to orbit hangar - why he thinks it's broken. He (mark316) writes: USE IMFD V4.2.1!!!!!!!! The Orbit Insert program in the later versions of IMFD is highly inaccurate, and it decreases your periapsis...

Just posting this for others in the future who might run into this issue (I couldn't find the answer by searching or reading docs, just found it by experimentation): If you don't have non-spherical gravity enabled, and you initialize an object's state vectors from TLE using this addon, the...

The IMFD Full Manual (IMFD Full Manual/Playbacks) explicitly says you need both 4.2.1 and 5.3 because of a problem with orbit insert, perhaps you could contact the author. Thanks for looking at this, it confused me, too.
