Well, if Mathias could simply comment on the issue? What can we expect at what 
timescale? (And how do you know these things - I've never read about any plans 
to include orbital rendering here).

According to the Celestia people, their textures are distributed under variants 
of Creative Commons, prohibiting commerical use. 

So I think in the long run we need to derive them directly from NASA Blue 
Marble. However, for the time being I simply intended this as a demo to get 
things on the way, to be replaced by a more sophisticated solution later, so I 
guess making it available as addon under Creative Commons terms does the trick 
for now.

Okay, so then the limits are probably really the grey, red and dark zone of the 
rendering engine rather than the FMD - can anyone comment on those? I can 
probably fix the issues by re-defining the light in the shaders of spacecraft 
models so that everything doesn't go dark, but that's a truly ugly fix.

That seems like a nice second spacecraft in the collection :-)

Hm, yes - I was rather thinking of real spacecraft than Star Trek. But yes, I 
think the Trekkies might like to take their shuttles into orbit for a ride.
