First of all thanx for this really cool proram!
But could it be that Mir, ISS, Hubble, Gemini and F7 are rotating in wrong direction around earth?
As far as i know, space rockets were launched in the direction of earth rotation to use it for additional speed.
Fixed by adding a "-" at the period in solarsys.ssc.
The rotation of Moon seems not to be correct because u can see the backside of Moon from Earth. (does anyone have the correct values?)
One feature that would be cool is reloading all data without restarting celestia per hotkey
