How to increase Celestia`s popularity

[AlextheFirst]

Many folks with are running Celestia 4 first time judging this program
from what they see at the once. So thinks like black hole, voyagers,
hektor, additional galaxies, shorex mars, SL 9... in default installer
could be usefull... I think about 2 additional megs could not be painfull.
Chris, what is Your oppinion?

Too Author of black hole: Could You add another one in center of milky
way?

And a question: Where i can find most recently data for ISS and HST orbit? Or how to recount these from http://www.heavens-above.com/ ?

Alex,

Probably the best source of orbital parameters is JPL's Horizons Ephemeris server. http://ssd.jpl.nasa.gov/horizons.html It isn't perfect (e.g. the orbital parameters for the Integral gamma-ray telescope were projections from before the satellite was actually launched, the last time I checked) but for most objects, it's very good.

Otherwise, a Google search for variations on the keywords
orbital parameters ISS
should find some useful pages.

I hope this helps a little.
