Editing Atmosphere

An atmosphere is the nasty sticky bit around a sufficiently large planet. From an Orbiter pilot's point of view, there are basically three sorts:

* Thin enough to give little aerodynamic benefit, thick enough that you can't just ignore them. Example: [[Mars]]

* Thick enough to be useful aerodynamically; re-entry needs some care, but with sufficient preparation no fuel need be expended after the deorbit burn if a runway is available for landing. Example: [[Earth]], [[Titan]]

* Thick enough to impair vehicle thrust if the complex [[flight model]] is enabled. Example: [[Venus]]

-'''Atmosphere''' is the general name for a layer of gases that may surround a material body of sufficient mass. The gases are attracted by the gravity of the body, and held fast if [[gravity]] is sufficient and the atmosphere's temperature is low. Some planets consist mainly of various gases, and thus have very deep atmospheres.
