ORBITER-FORUM will be temporarily closed at 2026-07-23 18:00 UTC while we complete some OF maintenance tasks. The amount of downtime is expected to take up to one hour, but probably less.
Assuming you have configured the video and other options in the Orbiter Launchpad dialog, you are ready to take off. Pick a scenario from the list, and click the "ORBITER" button.
In a nutshell, the most important controls are on the numerical pad of your keyboard: Ctrl+ for increasing main thrust, Ctrl- for decreasing main thrust or engaging retros, Ins and Del for increasing/decreasing hovers (if available), and cursor keys for attitude controls. You should read the Orbiter manual in the Doc folder for a full list of keyboard functions, as well as explanations of the instrumentation.
