Orbiter VS Celestia

Orbiter is more of a hardcore spacesim than a "game" in traditional sense, but also qualify. Source: 5 months ago

Orbiter does it, but I doubt the solution they use (whatever it is) would work with the game engine Nova uses. Reentry does it too. I guess it depends on how the game has been coded. Probably difficult to implement if it wasn't designed with time compression in mind to start with. Source: 7 months ago

Kerbal (KSP) is one way, but I would highly encourage you to seek out Orbiter Space Flight Simulator 2016 here http://orbit.medphys.ucl.ac.uk/ (all free) and its forum here https://www.orbiter-forum.com/. Tens of thousands of hours of work here for your enjoyment, when you look at the base simulator (Dr. Martin Schweiger's work), the rendering engines, the vessels, the mods and the expertise from the community ......

I’ve searched a bit and found this: http://orbit.medphys.ucl.ac.uk/ Has anyone played orbiter ? Source: 11 months ago

This looks amazing! I don't play KSP but Orbiter, not sure if you've heard of that? Would it be easy to make this compatible with the keyboard keys Orbiter uses? Source: 12 months ago

I think Celestia could be a good one. I also thought about SpaceEngine, but AFAIK it was kind of terrible at generating realistic planetary systems, among other things (pricey, huge, etc.). Source: about 1 year ago

Celestia was something I played with before. Pretty interesting. Source: about 1 year ago

Celestia looks as though it would do it. Source: over 1 year ago

I'm looking for data and software to visualize the Apollo 17 trajectory (especially the "powered descent", lunar rendezvous and entry). I'm thinking of using celestia. I'm look for a data tables as well (time stamp, position for each part of the stack). Any tips are appreciated. Source: over 1 year ago

Yes, that's Celestia most likely. I'm not sure it is still maintained though. Source: over 1 year ago
