Re: Spacecrafts for Celestia

Compton GR Observatory... alternative model... We learn every day. Another subject: do you have a method to generate data .xyz files starting from the ephemeris data of the Horizon site? In this I think of the orbits of the satellites at the point of Lagrange. Yes, Gironde... I have software which c...

Re: Spacecrafts for Celestia

If you send a properly formatted email message to Horizons, it will return an xyz trajectory file which needs only minimal editing to be compatible with Celestia.

Thanks very much Selden...

Re: Spacecrafts for Celestia

Versions of Celestia before v1.5.0 use UTC to calculate times and positions. Unfortunately, UTC includes "leap seconds" in order to stay aligned with the Earth's varying rotation. Leap seconds happen essentially randomly, when they are needed. Although Celestia does incorporate a table of ...

The solar panels of orbital spacecrafts looks like the atmosphere of the planets, around they rotate... if the satellite is on Earth's orbit, then they reflect more of the blue color ... around the moon is the color of the moon ... that is simple ...

Re: Spacecrafts for Celestia

Thank you for your positive reply about my request for Launch pads from Orbiter, and I believe it's not an easy task, but if I can help you with textures (sorry, I'm unable to help in modelling), I'm here.
Thank you very much Goofy... :smile:
