Start/stop time. When paused the Earth does not rotate and launch simulations do not run.
Toggle coordinate system axis and equatorial plane visualisations.
Mute/enable burn and crash sounds.
Clear all orbits and launches.
× n buttons change the "speed" of time to n-times real-time speed.
OrbitsTo visualise an orbit enter a name for it and click "add orbit". Use the sliders to adjust the elements of the orbit. You can also type in values after clicking the corresponding
icon or the numerical value of the parameter.
Drag this icon into a launch to start a simulation with the current orbital parameters.
Click to toggle the display of the orbital plane and angle visualisations.
Click to toggle only the orbital plane visualisation.
LaunchesTo add a launch simulation enter a name for it and click "add orbit". Use the sliders to adjust latitude (φ) and longitude (λ) of the launch as well as the longitude of the ascending node (Ω). You can also type in values after clicking the corresponding
icon or the numerical value of the parameter. You can select the latitude and longitude of a few well known launch facilities by clicking on the name of the launch.
Toggles the view of the burn profile editors.
Selecting this icon causes the camera to follow the launched rocket as it moves along the trajectory.
