So I have a theory based on the achievements for enhanced edition. There are three states on interacting with a planet, flyby, orbit, and suborbit. If you think of that in descending order you have to flyby before you orbit and orbit before suborbit.
Because you start on Kerbin you are already in a suborbit and have bypassed flyby and orbit. This was consistent with the corresponding achievement in enhanced edition where you unlock flyby not by entering space but when you return from one body to Kerbin. I got the enhanced edition achievement by returning from solar orbit and having a flyby of Kerbin. So if you returned from another planet this would be the more logical progression to hit the achievement.
Another part of my theory is how the rover achievement was bugged where it was tied to vehicle class. If you look at my guide, a rover that landed on the mun that was classified as a space craft wouldnt unlock the rover achievement. But if you landed any part, even debris, on the mun and reclassified it as a rover it would pop so the game is looking at a vessel by class and treating it as unique or different from the mothership.
I have never tried in depth but if someone could create a ferry to take something to minmus as a named and classed vessel as a spaceship and detach and rename and reclass the smaller vessel that the game then treats as a unique vessel that has only existed on minmus or at least never been to Kerbin. Then launch that new vessel into orbit around the sun and then slow down and flyby Kerbin.
I had tried to take a vessel directly into solar orbit and undock a smaller one and rename etc and it didnt work. I dont know if it didnt register or the trick is to launch from suborbit first since I was in orbit around the sun as opposed to being in a suborbit on minmus. Or that I didnt do the undock and reclass in the correct order. IE make a sub vessel in the aircraft hanger and then add as a sub part in the vehicle assembly building.
