Using NASA's General Mission Analysis Tool (GMAT), Cartesian coordinates were generated for a trajectory from the Earth to the Moon. The interactive visualization depicts the Earth, Moon, a space probe, and the trajectory. Buttons beneath the visualization include Start, Reset, Big Picture, View Satellite, and View Moon. Click on the Start button to animate the movement of the space probe along the trajectory. The Reset button puts the space probe in the initial position. The View Satellite and View Moon buttons changes the point of view. The view can be panned with a left click and drag and the middle mouse button enables zoom-in and zoom-out. The Big Picture button resets the view to show the entire trajectory.
