Visual Interactive Trajectory Design (VITD) is the process of simply "grabbing and dragging" spacecraft trajectories during the mission design process. Watch as we find a lunar free return trajectory in under 30 seconds, starting from a basic elliptical Earth-centered orbit with apogee just beyond Lunar distance.

This process provides the designer profound insight into the design space, and can be performed in any dynamical environment. Here we use NASA's General Mission Analysis Tool (GMAT, http://gmatcentral.org) along with the new OpenFramesInterface visualization plugin (https://gitlab.com/EmergentSpaceTechn....

Trajectories designed using VITD can be used as preliminary design products; they can be sent to optimizers as "initial guesses", or used in downstream systems engineering tasks such as hardware selection, thermal/radiative analysis, etc.
