Satelites are The Main View, Since in other Simulations, It has been invisible due to Full Zoom-Ining, They look a bit realistic. But it can do nothing in the simulation, Just Orbits around and Views the Planet/Moon's Surface. You can use buttons that work on Satelites, But They are quite too hard since there might be no things that would help do things.
Jets are familiar, But orbit faster than Satelites. They are also the Main View and might have buttons that help do things on the Jet, They also are Realiastic, But it uses diffrent parts. Since you find Simulations that add to this, Then just watch.
