Initially reported a month ago by @DaveBowman2001, after #71 was merged. My comments then:

The definition for Huygens with Cassini has FixedRotation { Inclination 90 AscendingNode 90 }
Changing this to 0 or 180 puts Huygens on its side. So rotating it another 90 degrees should fix the orientation, right? No! Values of -90 or 270 result in the original wrong orientation!

Celestia Origin defines Huygens as two separate objects - attached to Cassini, and in free flight - with different Orientation parameters. That may be the only way to make Huygens' orientation always correct, but I really don't want to do that...

Maybe I'll look into this further (along with finally updating asteroids) some time when I'm willing to suffer through trying to get modeled objects' orientations correct. Until then, I'm open to any suggestions. Apparently, the same issue affects Galileo's probe (#76).
